In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-6, fig. 1 is a partial exploded view of a push-pull door lock according to an embodiment of the present invention; FIG. 2 is a schematic view of the lock body of FIG. 1 with the lock body removed; FIG. 3 is a cross-sectional view of the connection of the fixed block and the push-pull block of FIG. 2; FIG. 4 is a front cross-sectional view of FIG. 2; FIG. 5 is an enlarged view of a portion of section I of FIG. 2; FIG. 6 is a schematic diagram of the third gear assembly of FIG. 5.
It should be noted that, the "first direction X", "second direction Y" and "third direction Z" mentioned herein are defined in the direction of the door panel, and are defined in the installed state of the push-pull door lock. Wherein, the first direction X refers to the direction vertical to the plane of the door plate, namely the front-back direction taking the door plate as a reference; the "second direction Y" refers to the width direction of the door panel, i.e., the left-right direction with reference to the door panel; the "third direction Z" refers to the height direction of the door panel, i.e., the up-down direction with reference to the door panel. Therefore, the above directional terms should not be construed to limit the scope of the present invention in any absolute sense.
In a specific embodiment, the present invention provides a transmission device of a push-pull door lock, which is connected to a handle 1 and a lock tongue 41 of the push-pull door lock, and specifically includes a first transmission part connected to the handle 1 and a second transmission part connected to the lock tongue 41, as shown in fig. 1, when the handle 1 moves linearly along a first direction X, the first transmission part and the second transmission part cooperate with each other to drive the lock tongue 41 to extend or retract along a second direction Y. Wherein the second direction Y is perpendicular to the first direction X.
In the invention, the handle 1 does not need to rotate in the process of opening and closing the push-pull door lock and only needs to linearly move along the first direction X, so that the space occupied by the handle 1 in the process of opening and closing the push-pull door lock is smaller, the space arrangement is facilitated, the limitation on the size and shape of the handle 1 is smaller, and the handle can be arranged according to the specific installation environment, thereby improving the user satisfaction of the push-pull door lock. Meanwhile, the push-pull door lock in the invention transmits the linear motion of the handle 1 to the linear motion of the lock tongue 41 through the cooperation between the first transmission part and the second transmission part, and the motion directions of the two parts are mutually perpendicular.
Further, the transmission device of the push-pull door lock further comprises a third transmission part connected with the first transmission part and the second transmission part, and the third transmission part can linearly move along a third direction Z under the drive of the first transmission part, so that the lock tongue 41 is driven to extend or retract along a second direction Y through the second transmission part. Wherein the third direction Z is perpendicular to the first direction X and the second direction Y.
The handle 1 moves along the first direction X, the lock tongue 41 moves along the second direction Y, and the linear motion in the first direction X can also be directly transmitted to the second direction Y through the transmission device, namely, the first transmission part and the second transmission part directly transmit, as shown in fig. 1, when the door panel directly transmits, the motion track of each part of the transmission device is located in a plane formed by the first direction X and the second direction Y. But in general the dimensions in the thickness direction of the door panel (first direction X) are small, which is detrimental to the arrangement of the components of the transmission.
In this embodiment, indirect transmission is realized through the third transmission part between the first transmission part and the second transmission part, specifically, the first transmission part transmits the linear motion of the handle 1 along the thickness direction (the first direction X) of the door panel to the linear motion along the height direction (the third direction Z) of the door panel, and then the linear motion of the lock tongue 41 along the width direction (the second direction Y) of the door panel is converted into the linear motion of the lock tongue 41 along the third direction Z.
In particular, as shown in fig. 2, the transmission of the motion between the first transmission portion and the third transmission portion is achieved by: the first transmission part comprises a first rack 111 and a first gear 23 which are meshed with each other, wherein the first rack 111 is connected to the handle 1 and extends in a first direction X, and the axis of the first gear 23 extends in a second direction Y. Meanwhile, the first gear 23 is fixed with a second gear 24 coaxial therewith, and the third transmission portion is provided with a second rack 21 meshed with the second gear 24, the second rack 21 extending in the third direction Z.
Therefore, when the handle 1 moves along the first direction X, the first rack 111 is driven to move along the first direction X, so as to drive the first gear 23 meshed with the first rack to rotate, the first gear 23 drives the second gear 24 fixedly connected with the first gear to rotate, and the second gear 24 drives the second rack 21 meshed with the second gear to move along the third direction Z, that is, drives the third transmission part to move along the third direction Z. As described above, when the third transmission portion moves in the third direction Z, the latch 41 can be driven to extend or retract in the second direction Y by the second transmission portion, and transmission of movement between the third transmission portion and the second transmission portion is described in detail below.
More specifically, as shown in fig. 2, the first gear 23 and the second gear 24 are integrally formed or fixed to each other, and the diameter of the first gear 23 is smaller than that of the second gear 24.
In this embodiment, since the first gear 23 and the second gear 24 are coaxially fixed, the rotational angular speeds of the two gears are equal, and meanwhile, since the diameter of the first gear 23 is smaller than that of the second gear 24, the arc length rotated by the second gear 24 is longer than that rotated by the first gear 23 in the same time, so that when the moving distance of the handle 1 along the first direction X is H, the moving distance of the third transmission part along the third direction Z is longer than H, and the space occupied by the transmission device along the first direction X is further reduced, so as to adapt to the installation requirement of the push-pull door lock.
Further, as shown in fig. 2, the handle 1 is fixed with a push-pull block 11, the push-pull block 11 is provided with the first rack 111 extending along the first direction X, and the push-pull block 11 can move linearly along the first direction X under the driving of the handle 1.
Further, as shown in fig. 2 and 3, the transmission device further includes a fixing block 31 fixed to the fixing plate 3 of the push-pull door lock, and along the second direction Y, the fixing block 31 is disposed close to the push-pull block 11, and at the same time, one of the end surfaces of the push-pull block 11 and the fixing block 31, which is close to each other, is provided with a groove extending along the first direction X, and the other has a stopper 112 extending toward the direction of the groove.
As shown in fig. 3, the fixed block 31 has a stopper 112, the push-pull block 11 is provided with a groove, and the groove and the fixed block 31 enclose a sliding rail 311, meanwhile, the dimension of the sliding rail 311 along the first direction X is greater than the dimension of the stopper 112 along the X direction, so that the stopper 112 can move along the first direction X in the sliding rail 311, and when the stopper 112 abuts against the inner wall of the sliding rail 311 along the first direction X, the stopper 112 and the inner wall of the sliding rail 311 limit the push-pull block 11 to move continuously, thereby preventing the push-pull block 11 from falling out from the sliding rail 311 when the handle 1 is pulled.
In the above embodiments, the transmission of the motion between the first transmission portion and the third transmission portion is described, and the transmission of the motion between the second transmission portion and the third transmission portion is described in detail below.
On the other hand, as shown in fig. 1 and 2, the second transmission part includes a third gear 25 and a driving rod 26, and the axis of the third gear 25 and the axis of the driving rod 26 both extend along the first direction X, wherein one end of the driving rod 26 is vertically fixed with the lock tongue 41, and the other end of the driving rod 26 is fixed to the third gear 25, specifically, the axis of the driving rod 26 coincides with the axis of the third gear 25, so that when the third gear 25 rotates, the driving rod 26 is driven to rotate around the axis (the first direction X) thereof, and thereby the lock tongue 41 is driven to linearly move along the axis (the second direction Y) thereof by the driving rod 26, so as to realize the extension and retraction of the lock tongue 41.
Specifically, as shown in fig. 5 and 6, the third transmission part is provided with a third rack 221 engaged with the third gear 25, the third rack 221 extending in the third direction Z, and thus, when the third transmission part is moved in the third direction Z by the drive of the second gear 24 in the first transmission part, the third rack 221 is moved in the third direction Z accordingly, thereby driving the third gear 25 engaged therewith to rotate and thus driving the driving lever 26 to rotate about its axis.
In summary, the motion transmission among the first transmission part, the second transmission part and the third transmission part in the transmission device is realized through a rack-and-pinion transmission mechanism, and those skilled in the art can understand that the transmission of the mutually perpendicular linear motion among the three transmission parts can also be realized through other mechanisms in the art, for example, the first transmission part and the second transmission part can respectively comprise mutually perpendicular sliding grooves, and further comprise right angle rods, two ends of each right angle rod are respectively positioned in the two sliding grooves and can slide along the corresponding sliding grooves, and the second transmission part and the third transmission part are similar to each other; or the first transmission part and the second transmission part can be respectively provided with sector gears, one ends of the two sector gears provided with tooth parts are mutually meshed, and the other ends of the two sector gears can move along mutually perpendicular tracks in a straight line. However, the rack and pinion transmission mechanism has the advantages of small occupied space and stable motion transmission, so the arrangement in the embodiment can be suitable for the characteristic of small internal installation space of the push-pull door lock.
Specifically, the second transmission part includes a third gear assembly, which includes a fixed cylinder 251, as shown in fig. 5 and 6, the fixed cylinder 251 being externally coated with the third gear 25 described above and being capable of rotating synchronously with the third gear 25. Meanwhile, as shown in fig. 1, one end of the driving rod 26 is fixed to the central hole of the fixed cylinder 251, and the other end extends into the lock body 4 of the push-pull door lock and is fixed to the lock tongue 41, so that when the fixed cylinder 251 rotates with the third gear 25, the driving rod 26 can be driven to rotate around its axis (first direction X).
Meanwhile, the axial dimension of the fixed cylinder 251 is larger than that of the third gear 25, so that the matching dimension with the driving rod 26 can be increased, and the connection reliability of the fixed cylinder and the driving rod can be improved.
Specifically, as shown in fig. 5 and 6, the central hole of the fixed cylinder 251 is a square hole 252, and accordingly, the driving rod 26 is a square rod fitted with the square hole 252.
In this embodiment, when the square driving rod 26 is matched with the square hole 252, the driving rod 26 and the fixed cylinder 251 can be ensured to be relatively static, so that the accuracy of the motion transmission between the third transmission part and the second transmission part is improved.
Further, as shown in fig. 2, the sliding door lock has a bottom plate 3, the bottom plate 3 is disposed parallel to the handle 1 and fixed to the door panel, and the fixing block 31 is fixed to the bottom plate 3. Meanwhile, the third transmission part is specifically a transmission plate 2 arranged parallel to the bottom plate 3 and the handle 1, and the transmission plate 2 can slide relative to the bottom plate 3 under the drive of the first transmission part.
Specifically, as shown in fig. 2 and 5, the driving plate 2 is provided with a driving hole 22, and the sidewall of the driving hole 22 is provided with the third rack 221, and the third gear 25 is located in the driving hole 22 and is engaged with the third rack 221.
In the present embodiment, the plate-like third transmission portion can further reduce the size of the transmission in the first direction X.
On the other hand, as shown in fig. 2, the transmission device further includes a return spring 5 extending along the third direction Z, one of two ends of the return spring 5 along the axial direction is a fixed end, and the other end is a movable end, and may be configured as: the fixed end is fixed on the bottom plate 3, and the movable end is fixed on the transmission plate 2. Therefore, when the push-pull door lock is opened by an external force, the driving plate 2 moves along the third direction Z and drives the return spring 51 to move so as to compress or elongate the return spring 51, when the push-pull door lock is closed, the external force disappears, the return spring 51 stretches or retracts to an initial state under the action of the return force, so that the driving plate 2 is driven to move along the third direction Z, and the moving direction is opposite to that of the opening, and the driving plate 2 drives the handle 1 and the lock tongue 41 to reset through the first driving part and the second driving part respectively.
Alternatively, the return spring 5 may be provided as follows: as shown in fig. 4, two ends of the return spring 5 along the axial direction are respectively fixed on the first movable baffle plate 52 and the second movable baffle plate 53, and the first movable baffle plate 52 and the second movable baffle plate 53 are both fixed on the transmission plate 2, and both can move along with the transmission plate 2. Meanwhile, the structure shown in fig. 4 is formed by the first fixing plate 54 and the second fixing plate 55 fixed on the bottom plate 3, and the first movable baffle piece 52 and the second movable baffle piece 53 are both positioned between the first fixing plate 54 and the second fixing plate 55 and are abutted against the corresponding fixing plates.
In this embodiment, since the two ends of the return spring 5 are fixed to the driving plate 2 through the corresponding movable blocking pieces, both can be used as the movable ends, and by providing two fixing plates, both can also be used as the fixed ends. The specific working process is as follows:
When the handle 1 is pulled up, the transmission plate 2 moves along the arrow b direction in fig. 2, the two movable baffle plates move along with the movement, and the first movable baffle plate 52 is blocked due to the arrangement of the first fixed plate 54, so that one end of the return spring 5 connected with the first movable baffle plate 52 is a fixed end, one end connected with the second movable baffle plate 53 is a movable end, and the return spring 5 is in a compressed state in the opening process of the push-pull door lock; when the external force is removed, the handle 1 and the lock tongue 41 are restored under the resilience force of the restoring spring 5.
Further, as shown in fig. 4, the spring shaft 51 is fixed to the first fixing plate 54 and the second fixing plate 55, and the restoring spring 5 is sleeved on the spring shaft 51, so that the restoring spring 5 can stretch along the spring shaft 51, and meanwhile, the first movable baffle plate 52 and the second movable baffle plate 53 can move along the spring shaft 51.
In this embodiment, by providing the spring shaft 51, the stability of the telescopic movement of the return spring 5 can be improved, and the return spring can be used as a guide rail for the movement of the two movable flaps.
In the above embodiments, as shown in fig. 2, if the push-pull door lock is in the open state and the handle 1 is pulled up, the first gear 23 and the second gear 24 rotate anticlockwise, so as to drive the driving plate 2 to move along the arrow b direction in fig. 2, and the third gear 25 drives the driving rod 26 to rotate anticlockwise, so as to drive the lock tongue 41 to retract leftwards; when the push-pull door lock is in the closed state, the transmission plate 2 moves in the direction of arrow a in fig. 2, thereby driving the second gear 24 and the third gear 25 to rotate clockwise, thereby driving the handle 1 to reset, and simultaneously driving the latch tongue 41 to extend rightward, and the push-pull door lock is restored to the locked state.
Meanwhile, since the fitting relation of the components of each rack and pinion transmission mechanism is fixed, in each of the above embodiments, when the handle 1 is pulled up, the latch tongue 41 moves leftward, and when the handle 1 is restored to the original state downward, the latch tongue 41 moves rightward.
In general, according to the difference of installation environments, the door may be opened to the left or may be opened to the right, wherein opening to the left means that the hinge of the door is located at the left side of the door panel, and the push-pull door lock is located at the right side of the door panel, and at this time, the lock tongue 41 is opened to the left and closed to the right, that is, in this state, the handle 1 is pulled up, the push-pull door lock is opened, the handle 1 is pressed down, and the push-pull door lock is closed. The right opening means that the hinge of the door is positioned on the right side of the door plate, the push-pull door lock is arranged on the left side of the door plate, at this time, the lock tongue 41 is closed leftwards and opened rightwards, namely, in the state, the handle 1 is pulled upwards, the door lock is closed, the handle 1 is pressed downwards, the door lock is opened, and the initial state of the push-pull door lock is the state that the door lock is opened, so that the use habit of a user is obviously not met. Therefore, the push-pull door lock in each of the above embodiments is not suitable for a door opened rightward.
In order to enable the push-pull door lock to be suitable for doors which are opened leftwards and rightwards, the invention further provides the following structure:
