Description
Technical Field
The invention relates to a door lock, in particular to a door lock with a rotary cover.
Background
Locks are generally classified into mechanical locks and electronic locks according to unlocking recognition modes. Mechanical locks typically identify the identity of a user by adapting the lock cylinder to a key. The electronic lock generally uses an information collection device, such as an IC card collection head, to collect IC card information, or uses a fingerprint information collection head to collect fingerprint information of a user, and then sends the collected information to a recognition center for identity recognition. In a conventional electronic lock, in order to facilitate information collection, the information collection device is generally directly exposed on a panel of the lock. However, the exposed arrangement mode makes the information acquisition device easily gather dust and contact water vapor to influence the acquisition precision, and is also very easily damaged by collision of other foreign objects. In order to solve the above-mentioned problems, a new generation of electronic locks are generally provided with a protective cover, for example, in chinese patent No. 201310575498.X, which is filed in 11/18 of 2013, a lock with a movable cover is described, and the lock includes a cover capable of being mounted on a door leaf and a movable cover rotatably mounted on the cover. The surface cover comprises a surface cover main body and a small panel embedded on the surface cover main body, wherein the small panel is provided with a shaft hole, the movable cover is provided with a rotating shaft capable of rotating in the shaft hole, the rotating shaft comprises a transition part, and the cross section outline of the transition part is at least provided with an arc part and a protruding fulcrum part opposite to the arc part; the face cover is also provided with an elastic arm, the arc-shaped part is propped against the elastic arm, and the fulcrum part is propped against the wall body of the shaft hole. An auxiliary positioner is further arranged between the movable cover and the small panel, and the auxiliary positioner comprises two jacks arranged on the small panel and two pins arranged on the movable cover. The movable cover is positioned onto the small panel when pins are inserted into the receptacles. After the movable cover 2 is pried by hands, the movable cover 2 can automatically swing under the coordination action of the arc-shaped part, the fulcrum part and the elastic arm. After observing the lockset product of the patent 201310575498.X, it can be found that in the process of swinging the movable cover, the inner side surface of the movable cover, pins arranged on the movable cover, fingers for operating the rotary cover and the like can form friction with the outer side surface of the panel, so that the friction is accumulated and tired day by day, obvious scratches are formed on the outer side surface of the panel, the appearance of the panel is seriously influenced, and particularly, the outer side surface of the panel is a smooth surface and is more prominent; therefore, it is necessary to further change the positioning structure of the screw cap to improve the use effect.

In view of the above, the present invention proposes a door lock with a screw cap, the door lock comprising a panel and a screw cap capable of swinging; the method is characterized in that: the panel is provided with a window peripheral wall protruding out of the panel, a central area surrounded by the window peripheral wall is provided with a window which can be covered by the spiral cover, the spiral cover is positioned at the outer side of the window peripheral wall, and the outer surface of the spiral cover is provided with a spiral cover decorative relief pattern; the rotary cover is characterized by further comprising a rotary shaft fixedly connected to the rotary cover and a rotary shaft connecting device used for connecting the rotary shaft, wherein the rotary shaft connecting device is arranged above the window, and the rotary shaft is rotatably arranged on the rotary shaft connecting device.
The panel is provided with a window peripheral wall protruding out of the panel, a window which can be covered by the spiral cover is arranged in the central area of the window peripheral wall, the window peripheral wall is firstly defined to be arranged on the panel, the window peripheral wall can be an independent part and can be detachably embedded on the panel, can also be an independent part connected to the panel in a welding, threaded connection mode and the like, and can also be a protrusion integrally formed with the panel. It is further defined that the window is disposed in a central region of the peripheral wall of the window, either in a configuration penetrating the panel or in a configuration not penetrating the panel. In addition, the window peripheral wall is defined to protrude from the panel such that an outer side surface of the window peripheral wall is higher than an outer surface of the panel around the window peripheral wall.
The peripheral wall of the window may be continuous and extend around the window, or may be discontinuous and extend around the window after removing portions. As for the surrounding range, it is also possible that the window peripheral wall may be one full, half or quarter turn around the window. In addition, a peripheral area of the peripheral wall of the window protruding from the panel position is defined, namely, a certain height difference distance is formed between the outer side face of the peripheral wall of the window and the outer side face of the peripheral area of the panel position. In this way, there is also a certain distance between the inner side of the screw cap arranged outside the peripheral wall of the window and the surrounding area of the panel position where the peripheral wall of the window is located.
The spiral cover is positioned on the outer side of the window peripheral wall, and the characteristic meaning includes that the inner side face of the spiral cover is attached to the outer side face of the window peripheral wall, or a very small distance is reserved between the inner side face of the spiral cover and the outer side face of the window peripheral wall.
The rotating shaft is fixedly connected to the rotating cover, and the characteristic meaning comprises that the rotating shaft and the rotating cover are of an integrally formed structure, so that a relatively stable connecting structure is formed between the rotating shaft and the rotating cover; or the rotating shaft and the rotating cover are in a split structure but are connected into a whole through threaded connection and other structures.
Wherein, the spiral cover decorative relief pattern is a stereoscopic decorative pattern or texture with a certain modeling of rugged.
Wherein the spindle connection is arranged above the window, which means that the spindle connection may be arranged either on the window peripheral wall above the window or on the panel around the window peripheral wall above the window.
According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that:
1. The window peripheral wall protruding from the panel is arranged around the window, and the spiral cover is positioned on the outer side of the window peripheral wall, so that the window peripheral wall can become a decorative frame of the window, and the edge line of the window is roughened, so that the window is plump, stable and good in atmosphere. In addition, the peripheral wall of the window can keep a certain distance between the inner side surface of the spiral cover and the panel, so that the spiral cover is prevented or reduced from scratching the outer side surface of the panel in the swinging process, and meanwhile, friction resistance between the inner side surface of the spiral cover and the panel is reduced, and the spiral cover is enabled to slide more lightly in the swinging process.
2. The outer side surface of the spiral cover is provided with the spiral cover relief decorative pattern. In this way, the relief decorative patterns of the spiral cover can be firstly interspersed on the outer side surface of the spiral cover, so that the decorative effect of the spiral cover is optimized. In addition, because the relief decorative pattern of the spiral cover has an uneven three-dimensional shape, a human hand can apply force to the spiral cover more easily through the relief decorative pattern, and the relief decorative pattern of the spiral cover becomes an adhesive force part for screwing or unscrewing the spiral cover. Therefore, the hands of the person do not need to contact the panel too much, dust or bacteria adhered to the panel are reduced or prevented from contaminating the hands of the person, and dust, greasy dirt or water adhered to the hands of the person can be reduced or prevented from contaminating the panel, so that the appearance or the service life of the panel is influenced.
Further, the panel relief decorative pattern may be provided on the panel located at the periphery of the peripheral wall of the window. In this way, the panel relief decorative pattern and the spiral cover relief decorative pattern are mutually reflected, and the appearance effect of the door lock is further optimized.
In order to enable the spiral cover to have a light sliding hand feeling in the left and right swinging process, the further technical scheme can be that the rotating shaft connecting device comprises a bearing, a bearing positioning hole is formed in the upper portion of the window, the bearing positioning hole is in a step shape and comprises a first hole with a small diameter and a second hole with a large diameter, the first hole is close to the outer side of the panel, the bearing is tightly matched with the second hole, and the rotating shaft is axially inserted into the bearing hole of the bearing. Therefore, the bearing can provide rotary support for the rotating shaft, reduce friction resistance generated in the moving process of the rotating shaft, enable the rotating cover to slide slightly and feel better in the left and right swinging process. The bearing positioning holes can also enable the bearing to be positioned on the panel in a relatively simple structure, and the bearing positioning holes can be positioned in a shared arrangement space with part of the wall body in the peripheral wall of the window, so that the structure of the panel is more compact and concise, and the bearing positioning holes can also be positioned in other proper areas of the panel above the peripheral wall of the window. The bearing can be a ball bearing, a sliding bearing or the like, and the sliding bearing can be a standard sliding bearing purchased from outsourcing or a sliding support structure which is directly machined on the panel and is equivalent to the sliding bearing.
The bearing positioning hole is in a step shape and comprises a first hole with a small diameter and a second hole with a large diameter, the first hole is close to the outer side of the panel, and the bearing is tightly matched in the second hole. In this way, a radially extending step surface is formed between the first and second holes, by which the bearing can be initially positioned axially without being able to easily run out to the outer space of the panel. In addition, the bearing is tightly matched and installed in the second hole, so that radial movement of the bearing can be reduced, the spiral cover is enabled to swing leftwards and rightwards more stably, meanwhile, the outer ring of the bearing is reduced or avoided to obviously rotate radially in the second hole, and abrasion occurs due to long-term friction with the inner wall of the second hole, so that the installation stability and the rotation stability of the whole bearing are affected.
Under the action of the bearing, the rotary cover can swing left and right to open or cover the window. After opening the window, the screw cap may be rotated to an improper position by its own weight without properly positioning the screw cap. In view of this, it is necessary to position the screw cap in the open state. Further technical scheme can be, pivot connecting device still includes set screw, spring pad the inboard tip of pivot is provided with the pivot screw thread, the set screw passes through the pivot screw thread connection to in the pivot, the spring pad sets up the set screw the screw head with between the bearing, so when the set screw is in the axial taut pivot, the spiral cover can stay in the arbitrary angular position in the swing range.
The rotating shaft threads can be external threads, and the external threads are arranged on the outer side wall of the inner side end part of the rotating shaft. At this time, the positioning screw is provided with an axially extending screw connection hole, the screw connection hole is provided with an internal thread, and the inner side end part of the rotating shaft is screwed in the screw connection hole. The rotating shaft threads can also be internal threads, and the internal threads are arranged in axially extending rotating shaft connecting holes on the inner side end part of the rotating shaft. At this time, an external thread is arranged on the outer side wall of the positioning screw, and the positioning screw is screwed in the rotating shaft connecting hole.
And a spring pad is arranged between the screw head of the positioning screw and the bearing. Thus, when the set screw is locked to narrow the interval between the screw head and the bearing to press the spring pad, the elastic acting force exerted on the set screw by the spring pad can give a certain axial tensioning force to the rotating shaft, so that the rotating shaft can maintain a constant tensioning state for a long time.
When the set screw tightens the rotating shaft in the axial direction, the rotating cover can stay at any angle position in the swing amplitude. The above features define the way and structure of positioning the screw cap within the swing amplitude. For example, when the set screw tightens the rotating shaft in the axial direction, the rotating shaft connecting part of the rotating cover is directly attached to the window peripheral wall, so that continuous friction resistance can be formed between the rotating shaft connecting part of the rotating cover and the window peripheral wall. Or a transition flat gasket which will be discussed below is arranged, the transition flat gasket is sleeved on the rotating shaft and is positioned between the rotating shaft connecting part of the spiral cover and the peripheral wall of the window, and when the positioning screw stretches the rotating shaft in the axial direction, the transition flat gasket is simultaneously attached and arranged between the rotating shaft connecting part of the spiral cover and the peripheral wall of the window, so that continuous friction resistance can be formed between the transition flat gasket and the spiral cover. Thus, when the positioning screw tightens the rotating shaft in the axial direction, the rotating cover can overcome the dead weight by means of friction resistance and stay at any angle position in the swinging amplitude.
It should be noted that the "tightening" first defines an operation of changing the axial position of the rotation shaft by screwing the set screw. When the set screw tightens the spindle in an axial direction, the spindle will move in an axial direction in a direction away from the cover portion, thereby bringing the screw cap relatively closer to the panel, reducing the axial gap between the panel and the screw cap. Second, the "pull-up" defines the amount of axial force applied to the shaft by the set screw. The axial force is not too great to cause the screw cap to be tightly attached to the panel so that the screw cap cannot swing within the swing amplitude. The axial force is not too small to cause an excessive axial clearance between the screw cap and the panel to cause the screw cap to fail to stay in any angular position within the swing amplitude. In order to enable the screw cap to swing left and right on the panel and stay at any angular position within the swing range, the force of the set screw to tighten the rotating shaft in the axial direction must be proper.
Further technical scheme may be, still including the cover is established the uide bushing on the set screw, thereby the uide bushing is T and has horizontal pullover and vertical cover main part, wherein horizontal pullover top is leaned on the bearing, vertical cover main part inserts in the bearing hole of bearing, the spring pad is located the screw head of set screw with between the horizontal pullover, vertical cover main part with have axial clearance in axial direction between the pivot. In this way, the lateral sleeve provides relatively smooth support and uniform force to the spring pad, avoiding significant uneven deformation of the spring pad that could affect the tension applied to the spindle. The longitudinal sleeve main body is inserted into the bearing hole of the bearing, so that the radial clearance between the set screw and the wall of the bearing hole of the bearing can be reduced, the radial displacement of the set screw is reduced, and the release of the set screw caused by long-term radial displacement of the set screw is reduced or avoided. In addition, an axial gap is formed between the longitudinal sleeve body and the rotating shaft in the axial direction. In this way, the longitudinal sleeve body does not directly contact the rotating shaft to interfere the radial rotation of the rotating shaft, and the rotating shaft is not propped up to death to influence the adjustment of the axial position of the rotating shaft. The axial gap can provide an axial adjustment space for axial displacement of the shaft.
The further technical scheme may be that the screw cap includes a rotating shaft connecting portion and a covering portion, and the covering portion of the screw cap can expose the window and cover the window in the swing process of the screw cap; the rotating shaft is fixedly connected to the rotating shaft connecting part; a transition flat gasket is arranged between the rotating shaft connecting part of the spiral cover and the peripheral wall of the window, and the transition flat gasket is sleeved on the rotating shaft. Therefore, by means of the transition flat gasket, an extremely small axial distance is formed between the rotating shaft connecting part of the spiral cover and the peripheral wall of the window, and the phenomenon that the rotating shaft connecting part of the spiral cover and the peripheral wall of the window are rubbed with each other for a long time to be worn so as to influence the tightness of the rotating shaft can be avoided. And when the set screw tightens the rotating shaft in the axial direction, friction resistance can be formed between the transition flat gasket and the rotating shaft connecting part of the rotating cover so that the rotating cover can stay at any angle position within the swing amplitude. Secondly, under the condition of reasonably setting the connection part of the rotating shaft or the combination structure of the peripheral wall of the window and the transition flat gasket, the transition flat gasket can be used for enabling the covering part of the spiral cover to form extremely small axial distance with the peripheral wall of the window, so that the covering part is prevented from being directly attached to the peripheral wall of the window to slide and scratch the peripheral wall of the window, and meanwhile, the influence on the light sliding degree caused by the resistance applied by the peripheral wall of the window in the swing process of the spiral cover is reduced.
The further technical scheme can be that an inductor is arranged on the inner side of the peripheral wall of the window, and an electric signal of the inductor is connected with a central controller of the door lock; a trigger magnet corresponding to the inductor is arranged below the spiral cover, and the trigger magnet can trigger the inductor to generate an induction signal. Therefore, after receiving the induction signal, the central controller can automatically judge the next action such as starting a certain device on the door lock, so that the use of a user is facilitated.
The further technical scheme can be that an unlocking signal acquisition device is further arranged in the window area, and the unlocking signal acquisition device is electrically connected with a central controller of the door lock; the unlocking signal acquisition device is operated in response to the unscrewed cap. Thus, after the screw cap is unscrewed, the unlocking signal acquisition device can respond to the unscrewed screw cap to perform the next operation, for example, the unlocking signal acquisition device is started immediately, so that the manual starting operation of the signal acquisition device can be omitted, and the application friendliness of the door lock is optimized.
Since the present invention has the above-mentioned features and advantages, it can be applied to a door lock having a screw cap.

Detailed Description
The door lock structure with the portable screw cap, which applies the technical scheme of the invention, is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the door lock with the portable screw cap 2 comprises a panel 1, the screw cap 2, a rotating shaft connecting device 3, an unlocking signal collecting device 4, an inductor 5, a lock body (not shown in the figures) and the like.
A window 10 is arranged on the panel 1, a circle of window peripheral wall 11 protruding out of the window 10 is arranged around the window 10, the window peripheral wall 11 and the panel 1 are integrally formed, and the window 10 is positioned in a central area surrounded by the window peripheral wall 11; as a further embodiment, the peripheral wall 11 of the window may be provided as a separate plastic or metal part and connected to the panel 1 by means of a snap-fit or screw connection, the window 10 being located in a central region of the separate plastic or metal part and penetrating the panel 1.
The peripheral wall 11 may be formed to extend continuously around the window 10, or may be formed to extend intermittently around the window 10 after removing a part thereof. As for the surrounding range, it is also possible that the window peripheral wall 11 may be one full, half or quarter turn around the window 10. In this embodiment, the window peripheral wall 11 extends continuously around the window 10 for a complete revolution. A rotating shaft connecting device 3 is further arranged on the panel 1, and the rotating shaft connecting device 3 is positioned above the window 10. The door lock further comprises a rotary cover 2 arranged on the panel 1 in a swinging mode, the rotary cover 2 comprises a covering portion 21, a rotating shaft 22 and a rotating shaft connecting portion 23, the covering portion 21 is arranged on the outer side of the window peripheral wall 11, the outer side end portion of the rotating shaft 22 is fixedly connected to the rotating shaft connecting portion 23 of the rotary cover 2 and integrally formed with the rotating shaft connecting portion 23, and the inner side end portion of the rotating shaft 22 is rotatably arranged on the rotating shaft connecting device 3. The covering portion 21 of the screw cap 2 can expose the window 10 and also cover the window 10 during the swing of the screw cap 2. Of course, in other embodiments, the shaft 22 and the shaft connecting portion 23 of the screw cap 2 may be separate structures but may be integrally connected by a threaded connection or the like. A screw cap decorative relief pattern 210 is provided on the outer side surface of the screw cap 2, and a panel relief pattern 12 is also provided on the panel 1 located on the periphery of the window peripheral wall 11. The spiral cover decorative relief image 210 and the panel relief decorative image 12 are three-dimensional decorative patterns or textures having a patterned relief. The panel relief decorative pattern 12 and the screw cap relief decorative pattern 210 are mutually reflected, so that the door lock is more beautiful.
According to the technical scheme, the following steps are found: since a ring of window peripheral walls 11 protruding from the panel 1 is provided around the window 10, the screw cap 2 is disposed on the outer side of the window peripheral walls 11. In this way, the peripheral wall 11 of the window can become a decorative border of the window 10, and the border of the window 10 is roughened, so that the window 10 is plump, stable and air-friendly. The window peripheral wall 11 may further maintain a certain distance between the inner side surface of the cover portion 21 and the outer side surface of the panel 1, so as to avoid or reduce the scraping of the cover portion 21 on the outer side surface of the panel 1 during the swinging process, and at the same time, facilitate reducing the friction resistance between the inner side surface of the cover portion 21 and the outer side surface of the panel 1, so that the swing process of the screw cap 2 is lighter. In addition, the outer side surface of the spiral cover 2 is provided with the embossment decorative pattern of the spiral cover 2. In this way, the relief decorative pattern of the spiral cover 2 can be firstly interspersed on the outer side surface of the spiral cover 2, so as to optimize the decorative effect of the spiral cover 2. Secondly, since the relief decorative pattern of the screw cap 2 has an uneven three-dimensional shape and is relatively smooth, a human hand can apply a force to the screw cap 2 through the relief decorative pattern more easily. The relief decorative pattern of the spiral cover 2 becomes an adhesive force part for screwing or unscrewing the spiral cover 2. In this way, the human hand does not need to contact the panel 1 too much, so that dust or bacteria adhering to the panel 1 can be reduced or prevented from contaminating the human hand, and dust, greasy dirt or water adhering to the human hand can be reduced or prevented from contaminating the panel 1, thereby affecting the appearance or service life of the panel 1.
As shown in fig. 3 and 4, a bearing positioning hole 13 is arranged on the window peripheral wall 11 above the window 10, the bearing positioning hole 13 is stepped to include a first hole 131 of a small diameter and a second hole 132 of a large diameter, a radially extending stepped surface 133 is formed between the first hole 131 and the second hole 132, and the first hole 131 is located close to the outside of the panel 1. The shaft connecting means 3 comprises a bearing 31, such as a ball bearing, which bearing 31 fits tightly in the second hole 132. The inner end of the rotating shaft 22 is axially inserted into the bearing hole of the bearing 31 so that the rotary cover 2 can swing left and right on the panel by means of the combination of the rotating shaft 22 and the bearing 31. Thus, the bearing 31 can be initially axially positioned by the step surface 133 and cannot easily run to the outer space of the panel 1, and can provide rotation support for the rotating shaft 22, and reduce friction resistance generated by the rotating shaft 22 in the moving process, so that the rotating cover 2 is lighter and smoother in the left and right swinging process, and has better handfeel. In addition, the bearing 31 is tightly fitted in the second hole 132 in a mounting manner, so that radial movement of the bearing 31 can be reduced, the process of swinging the rotary cover 2 left and right is more stable, and meanwhile, obvious radial rotation of the outer ring of the bearing 31 in the second hole 132 is reduced or avoided, and abrasion is caused due to long-term friction with the inner wall of the second hole 132, so that the mounting stability and the rotation stability of the whole bearing 31 are affected. In addition to positioning the bearing 31 through the bearing positioning hole 13, the bearing 31 may be positioned on the panel 1 by welding, bonding, or the like in other embodiments.
Under the action of the bearing 31, the rotary cover 2 can swing left and right in a light sliding manner to open or cover the window 10. After opening the window 10, the screw cap 2 may be rotated to an improper position by self gravity if the screw cap 2 is not properly positioned. In view of this, it is necessary to position the screw cap 2 in the open state. As shown in fig. 3 and 4, the shaft connecting device 3 further includes a set screw 32, a spring pad 34, a shaft thread 220 is disposed at an inner end of the shaft 22, the set screw 32 is connected to the shaft 22 through the shaft thread 220, and the spring pad 34 is disposed between a screw head 321 of the set screw 32 and the bearing 31. So that the screw cap 2 can stay at an arbitrary angular position within the swing amplitude when the set screw 32 tightens the rotation shaft 22 in the axial direction.
The spindle thread 220 may be an external thread, which is disposed on an outer sidewall of an inner end of the spindle 22. At this time, an axially extending screw connection hole is provided in the set screw 32, an internal thread is provided in the screw connection hole, and an inner end of the rotating shaft 22 is screwed into the screw connection hole. In this embodiment, the spindle thread 220 is an internal thread, and the internal thread is disposed in an axially extending spindle connection hole on the inner end of the spindle 22. At this time, an external thread is provided on the outer sidewall of the set screw 32, and the set screw 32 is screwed into the spindle connection hole.
Wherein a spring pad 34 is provided between the screw head 321 of the set screw 32 and the bearing 31. Thus, when the set screw 32 is tightened to narrow the space between the screw head 321 and the bearing 31 and compress the spring pad 34, the spring pad 34 is elastically deformed and then gives a certain axial tension to the rotating shaft 22 by the set screw 32, so that the rotating shaft 22 can maintain a constant tension state for a long time.
Wherein, when the set screw 32 tightens the rotating shaft 22 in the axial direction, the screw cap 2 can stay at any angular position within the swing amplitude. The above features define the positioning structure of the screw cap 2 within the swing amplitude. For example, when the set screw 32 tightens the rotation shaft 22 in the axial direction, the rotation shaft connecting portion 23 of the screw cap 2 is directly attached to the window peripheral wall 11, so that a continuous frictional resistance can be formed between the rotation shaft connecting portion 23 of the screw cap 2 and the window peripheral wall 11. In the present embodiment, a transition flat gasket 6 is provided between the rotating shaft connecting portion 23 of the screw cap 2 and the window peripheral wall 11, and the transition flat gasket 6 is sleeved on the rotating shaft 22. A gasket positioning groove 134 for arranging the transition flat gasket 6 is arranged on the peripheral wall 11 of the window, and the groove depth of the gasket positioning groove 134 is smaller than the thickness of the transition flat gasket 6. When the set screw 32 tightens the rotating shaft 22 in the axial direction, friction resistance can be formed between the transition flat gasket 6 and the rotating shaft connecting part 23 of the rotating cover 2 so that the rotating cover 2 can stay at any angle position within the swing amplitude; in addition, by means of the transition flat gasket 6, firstly, a very small axial distance can be formed between the rotating shaft connecting part 23 of the rotary cover 2 and the window peripheral wall 11, so that abrasion caused by long-term mutual friction between the rotating shaft connecting part 23 of the rotary cover 2 and the window peripheral wall 11 is avoided, and the tightness of the rotating shaft 22 is further influenced; secondly, an extremely small axial distance is formed between the covering portion 21 and the peripheral wall 11 of the window, so that the covering portion 21 is prevented from directly attaching to the peripheral wall 11 of the window to slide and scratch the peripheral wall 11 of the window, and meanwhile, the influence on the light sliding degree caused by the resistance applied by the peripheral wall 11 of the window in the swinging process of the spiral cover 2 is reduced. In the case that the window peripheral wall 11 is not provided, the transition flat gasket 6 is sleeved on the rotating shaft 22 and is positioned between the rotating shaft connecting portion 23 of the rotating cover 2 and the panel 1.
The spring pad 34 is one of key components that enables the rotation shaft 22 to maintain a constant tension state for a long period of time, so that the stress condition of the spring pad 34 cannot be ignored. In order to be able to apply a uniform force to the spring washer 34, a first embodiment may be used (this way, which is relatively simple, the relevant view is omitted), in which a screw flat washer is provided, which is arranged between the spring washer 34 and the bearing 31 or between the screw head 321 of the set screw 32 and the spring washer 34, which screw flat washer has an axial distance in the axial direction from the spindle 22. Wherein the screw flat gasket has a working surface of relatively large radial extension. The working surface of the flat washer gives the spring pad 34 a relatively smooth support and a uniform force, avoiding a significantly uneven deformation of the spring pad 34 that would affect the tightening force applied to the spindle 22. In addition, since the screw flat gasket and the rotating shaft 22 have an axial distance in the axial direction, the screw flat gasket does not directly contact the rotating shaft 22 to interfere with the radial rotation of the rotating shaft 22, and does not top dead the rotating shaft 22 to affect the adjustment of the axial position of the rotating shaft 22. The axial gap can provide axial adjustment space for axial displacement of the shaft 22.
As shown in fig. 3 and 4, a second embodiment may be adopted, and the device further includes a guide sleeve 33 sleeved on the set screw 32, where the guide sleeve 33 is T-shaped and has a transverse sleeve head 331 and a longitudinal sleeve body 332, the transverse sleeve head 331 abuts against the bearing 31, the longitudinal sleeve body 332 is inserted into a bearing hole of the bearing 31, the spring pad 34 is located between the screw head 321 of the set screw 32 and the transverse sleeve head 331, and an axial gap L is provided between the longitudinal sleeve body 332 and the rotating shaft 22 in an axial direction. In this way, the lateral sleeve 331 provides relatively smooth support and uniform force to the spring pad 34, avoiding significant uneven deformation of the spring pad 34 that could affect the tension applied to the shaft 22. The insertion of the longitudinal sleeve body 332 into the bearing hole of the bearing 31 can reduce the radial clearance between the set screw 32 and the bearing hole wall of the bearing 31, and reduce the radial displacement of the set screw 32, thereby reducing or avoiding the occurrence of loosening caused by long-term radial displacement of the set screw 32. In addition, there is an axial gap between the longitudinal sleeve body 332 and the rotating shaft 22 in the axial direction. In this way, the longitudinal sleeve body 332 does not directly contact the rotating shaft 22 to interfere with the radial rotation of the rotating shaft 22, and does not press the rotating shaft 22 against the outside to affect the adjustment of the axial position of the rotating shaft 22. The axial gap can provide axial adjustment space for axial displacement of the shaft 22.
As shown in fig. 1 and 4, locking devices such as an unlocking signal collecting device 4 and an indicator lamp (not shown in the drawings) are arranged in the area where the window 10 is located, and the unlocking signal collecting device 4 and the indicator lamp are respectively connected with a central controller (not shown in the drawings) of the door lock in an electric signal manner and respectively work in response to the unscrewed rotary cover 2. An inductor 5 is arranged on the inner side of the peripheral wall 11 of the window, the inductor 5 is electrically connected with a central controller of the door lock, a trigger magnet 51 corresponding to the inductor 5 is arranged below the covering part 21 of the rotary cover 2, and the trigger magnet 51 can trigger the inductor 5 to generate a sensing signal. Thus, when the cover portion 21 of the screw cap 2 is unscrewed, the trigger magnet 51 arranged below the cover portion 21 is far away from the sensor 5 to trigger the sensor 5 to generate a sensing signal, after the sensing signal is transmitted to the central controller, the central controller respectively starts the unlocking signal acquisition device 4 and the indicator lamp, so that manual starting operation on the signal acquisition device can be omitted, the unlocking signal acquisition device 4 in the window area can be illuminated through the indicator lamp, and a user can observe the unlocking signal acquisition device 4 conveniently, so that the application friendliness of the door lock is optimized.
