Field of the Invention The present invention relates to a cylinder lock protection device that can prevent damage of a cylinder lock provided in a two-wheeled vehicle or the like. 1 〇 [Prior Art] In the past, there has been a case in which a cylinder lock for preventing a bicycle or the like from being placed in a two-wheeled vehicle or the like is illegally inserted into a keyhole of the cylinder lock by using a scissors or a screwdriver or the like. The cylinder lock protection device that is opened and broken (for example, see Patent Document 1). The protection device includes a baffle that can be rotated from a closed position in which the keyhole is closed to an open position in which the keyhole is opened, a torsion spring for pushing the baffle from the open position to the closed position, and a Fixing a baffle button at the open position, a magnetic 20 lock for locking the baffle by holding the baffle at the closed position, thereby closing the keyhole, and a function for releasing a magnet A magnetic key that locks the magnetic magnetic lock. According to the foregoing protection device, when the button is pressed, the shutter is rotatably moved to the closed position by the urging force of the torsion spring, whereby the keyhole can be closed, and when the magnetic lock (locking mechanism) is used When the magnetic key unlocks 200936861, the baffle can be rotatably moved to the open position. The baffle is constructed separately from the magnetic lock (locking mechanism) and thus they are operated through a slider. [Patent Document 1] JP-A-2003-239581 5 However, according to the above-described conventional cylinder lock protection device, since the shutter and the locking mechanism are formed separately from each other and thus they are separately operated by a slider, the following occurs. problem. That is, in order to obtain the operating range of the slider, the size of the device becomes large. Further, since the shutter is rotatably moved to the open position when the magnetic lock (locking mechanism) is unlocked by the magnetic key, the structure of the apparatus is complicated. SUMMARY OF THE INVENTION One or more embodiments of the present invention provide a cylinder lock protector that maintains its operability and that can be used with a simplified structure to reduce its manufacturing cost and its size. According to one or more embodiments of the present invention, a cylinder lock protection device for protecting a cylinder lock includes: a casing 1 disposed in a keyhole Sa formed in the cylinder lock S a baffle 2, rotatable within the housing 1 and movable between a closed position and an open position to open and close the keyhole Sa; the push mechanism 3 for the baffle 2 Pushing to the closed position by the open position; the locking mechanism 4' is for locking the shutter in the closed position; and the opening mechanism is "艮" for releasing the locked state of the shutter 2 locked by the locking mechanism 4 to The baffle 2 is moved from the closed position to the open position; and the operating mechanism 5 is configured to fix the baffle 6 at the open position. The 200936861 includes an operating portion protruding from the housing 1 and the operation is performed. The simple part is still released. The baffle 2"" is locked into a single member. 5 According to the cylinder lock protection device, since the operation portion can be used to release the state of the plate, and the plate and the locking mechanism are integrally formed as a single-member, the operation of the cylinder lock protection device can be maintained. And the structure is simplified, thereby reducing the manufacturing cost and size of the device. In addition, the baffle 2 can include a rounded edge portion 2 core #1, the striker 2 1 is inserted into the cylinder lock S with a key When the keyhole Sa is moved to the closed position, the rounded edge portion can be in contact with the key. When the edge portion of the seesaw to be in contact with the key is rounded, even if the opening mechanism is erroneously operated, the key is inserted into the key hole of the cylinder lock and the shutter is thus moved to the closed position. The key is held 15 and held in the baffle, and the key can be easily withdrawn. Further, the urging mechanism 3 may include a torsion spring 3 disposed on a shaft L different from the shaft lab of the baffle 2. When the urging mechanism is constituted by a torsion spring disposed on a shaft different from the shaft of the slab, the thickness of the structure of the present invention is compared with a structure in which a torsion spring is disposed on the rotation 20 of the damper Can be reduced. In addition, the baffle 2 may include a protrusion 2c' which is in contact with the torsion spring 3 and which can receive the urging force of the torsion spring 3, and the protrusion 2c and the torsion spring 3 may be respectively formed to have a damper 2 according to the baffle 2 The rotation angle changes the direction of the urging force applied to the projection 2c by the torsion spring 3 and the shape of the contact position between the springs 3 at the projection 200936861. The large and torsion spring is formed to have a shape that can change not only the direction of the pushing force applied to the protrusion by the torsion spring but also the position of the contact between the torsion spring and the protrusion. At this time, the twisting spring <the pushing force can efficiently transmit the torsion spring' so that the baffle can be surely operated. Further, a contact portion between the operation portion 5a and the shutter 2 may include a tapered portion 2ba. The contact portion between the operation portion and the baffle includes a tapered shape. The fixed state of the operation portion of the baffle plate can be more smoothly achieved. Other aspects and advantages of the present invention will be apparent from the following description, drawings and claims.

[Embodiment 1] DETAILED DESCRIPTION OF THE EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. One of the cylinder lock protection devices of this embodiment is a device disposed on the upper side of a keyhole of a cylinder lock disposed in a 10-wheeled vehicle, according to which the keyhole can be opened and closed by the outside. Thereby, the cylinder lock can be protected. As shown in Figures 1 to 4, the cylinder lock protection device mainly comprises a casing 1 having a box portion 1a and a cover portion 1b, a baffle plate 2, a torsion spring 3 as a pushing mechanism, and a composition The magnetic lock locking mechanism 4 (see Fig. 2), a magnetic key MK as an opening mechanism, and a button 5 as an operating mechanism. As shown in Fig. 2, the box portion 1a made of a molded article includes not only an insertion hole laa substantially formed in the center thereof (see Figs. 3 to 5), but also includes a setting in the insertion. The magnetic lock protrusion portion near the hole laa 2〇lab. A cylinder lock S of a vehicle can be inserted into the insertion hole laa, and the insertion hole laa also allows the keyhole Sa of the cylinder lock to face above the insertion hole laa. The magnetic lock projection portion lab includes a plurality of (in the embodiment, four) receiving holes lac on the front end surface thereof for receiving the associated magnet 透过 through its associated spring S1; and is also configured to lock the lock The circular portion 4a of the mechanism 4 can be rotatably 9 200936861 to fit the outer peripheral surface of the magnetic lock projection portion lab. Here, in Fig. 2, the symbol "a" indicates a loop for sealing between the circular portion of the lock mechanism 4 such as the magnetic lock projection portion lab. a cover portion lb made of a predetermined molded molding covers the surface side of the upper portion 5 of the casing portion ia to receive a component of the cylinder lock protection device such as the baffle 2, and is formed in the casing portion 1a In the inner space between the cover portions lb. The cover portion 1b includes a hole 1b formed at a position corresponding to an insertion hole iaa for inserting a start key (not shown) into the key hole Sa, and an operation portion into which the button 5 can be inserted A hole lbb of the portion 5a, and a hole 1bc into which the fitting portion 4a of the lock 10 mechanism 4 can be inserted. The operation portion 5a of the button 5 is assembled by the upper surface side of the cover portion lb and the button 5 and the locking mechanism 4 are respectively positioned on both sides and the hole lba facing the key hole Sa is disposed therebetween. . Here, the upper surface of the cover portion 1b is formed to be substantially flat except for the operation portion 5a of the button 5. The locking mechanism 4 is made of a non-magnetic material and is formed as a single member with the baffle 2, and the locking mechanism 4 includes a fitting portion 4b on the front surface side thereof, and most of them A fitting hole 4c on the back side. A magnetic key (opening mechanism) MK is engageable with the fitting portion 4b, and a magnet rim disposed on the front end of the magnetic lock projection portion lab can be fitted and fixed in the fitting hole 4c. When the locking mechanism 4 is assembled to the magnetic lock projection portion lab, the fitting holes 4c can be fitted and fixed to the magnet bore pushed up by the spring S1. That is, when the baffle 2 is positioned in the closed position, the receiving hole 1 formed in the front end of the magnetic 200936861 lock projection portion lab can be aligned with the fitting holes; and, at the closed position The magnets are moved into the plate holes 4c to thereby fix and lock the locking mechanism 4. On the other hand, the magnetic key MK is used to release the locked state of the shutter 2 generated by the locking mechanism 4, and the shutter 2 is moved from the closed position to the open position. The magnetic key MK is constituted by, for example, a portion integrally formed with a grip portion (a portion made of a resin) of a start key of a two-wheeled vehicle. Further, in detail, in the front end of the magnetic key MK, a plurality of magnets are buried at positions corresponding to the magnets. These magnets are provided such that the polarities of the magnets having different polarities on the upper surface side of the magnets are placed in a state in which the one magnetic key is fitted to the fitting portion 4b of the lock mechanism 4, respectively. The polarity of the surface side of the magnet Μ. According to this configuration, when the locking mechanism 4 (baffle 2) is locked, when the magnetic spoon is inserted into the embedded portion 4b, since the magnets 15 are disposed in the magnetic key MK The repulsive force generated between the magnets moves downward against the urging force of the spring S1, thereby releasing the locked state of the lock mechanism 4 (baffle 2). In this state, when the magnetic recording key is rotated, the locking mechanism 4 moves with the magnetic key MK due to the fitting of the fitting portion 4b with the magnetic key, so that the locking mechanism 4 can be The 20 baffle 2 rotates. As previously mentioned, the baffle 2 is integrally formed with the locking mechanism 4 and is made of a non-magnetic material. Moreover, the baffle 2 includes a closing portion 2a for covering the key hole Sa at the closed position, an arm portion 2b disposed and protruding outward from the closing portion 2a, and a The back surface of the baffle 2 protrudes from the projection 2c of 200936861. Thus, when the locking mechanism 4 is in contact with the magnetic lock projection portion lab and the former rotates around the latter, the closing portion remains in a position to close the hole 1ba of the cover portion 1b (a closed position) and - and The hole lba is separated to move between its open position (-open position), whereby the wheel (10) 5 can be opened and closed by the outside. Here, the overall shape of the baffle 2 can be arbitrarily changed depending on the overall shape and size of the casing 1 and the configuration of other constituent elements. The dog is 2c疋-which can be in contact with the torsion spring 3 and can accept the thrust of the torsion spring, and by this driving force, the baffle will be pushed from the opening position to the "Hei closed position" 2. The torsion spring 3 is a part constituting the pushing mechanism of the present invention; and, in order to push the push plate 2 from the open position to the closed position, the torsion spring 3 is disposed on the rotating shaft of the baffle 2 ( That is, the magnetic lock projection portion (4) is different on the shaft L. In detail, the torsion spring 3 is wound around a machine disposed on and protruded from the box portion a (or the cover finger), and the base end side thereof is defined The box portion is closed and the front end 3a side is in contact with the protrusion 2c so as to transmit its driving force thereto and 'as shown in Fig. 7' during the turning operation of the jaw board 2, © the torsion spring 3 The front end % side is always in contact with the protrusion ^. Further, the protrusion 2C and the torsion spring 3 are respectively formed to have a rotation angle ′ according to the rotation direction, and not only the direction of the driving force applied to the protrusion by the torsion spring 3 but also The opening position of the torsion spring 3 and the protrusion 2c can be changed. As shown in the figure, the protrusion 2c is formed to have a substantially elliptical opening in a predetermined direction when viewed from above. And the side of the front end 3a of the torsion spring 3 is formed such that it can be bent by a predetermined angle 12 200936861 With the position of the baffle 2, the driving force of the twisting elastic 3 can be efficiently transmitted to the projection 2c. ' 5 Q 10 15 Ο 20 ie 'as in Figures 7A to 7〇*' #The baffle 2 is rotated to the closed position by the open position (see Figure 7A) through the state shown in the fourth (4), respectively. See the 7D figure), the contact position and the connection between the front end 3a of the torsion spring 3 and the protrusion (four) degrees continuously change, whereby the urging force of the torsion spring 3 can effectively face the baffle 2 The direction of rotation is transmitted. Therefore, the urging force of the torsion magazine 3 can be efficiently transmitted to the baffle 2, whereby the actual operation of the baffle 2 is made. The arm portion 2b疋 can contact the portion of the arm material of the button 5 when the baffle 2 is positioned at the closed position; and the back surface of the coffee maker (the surface that can be in contact with the arm portion 5b of the button 5) ) formed as a tapered portion. In this way, the (four) tapered portion 2ba is formed in the contact portion (contact surface) between the arm portion and the broadcast plate 2 (arm portion 2b), so that the baffle 2 can be obtained more smoothly. It is fixedly coupled to the button 5 (operating portion). Here, the tapered portion may be formed on the arm portion 5b side of the flank 5 or on both the arm portion % and the arm portion 2b. The above-mentioned 'the striker 2' positioned at the open position without pressing the milk also includes - the part of the heart that is disposed and operated by the housing, that is, the remaining 5 can be relieved of the pressurizing operation The operating portion & produces the E1 state of the baffle 2. The plate is made of a resin member and includes the operating portion 5a and the arm portion %. Thus, when the baffle When the position 2 is positioned at the position, the milk is pushed up by the pushing force of the screw, and the arm 5bm is fixed to the arm 2b of the flap 2, thereby limiting 13 200936861. The rotation of the direction of the push (the direction toward the closed position of the shutter 2). On the other hand, when the button 5 is pressed against the urging force of the coil spring 82, it is pressurized. In this case, the arm portion 5b is also moved downward by 5 according to the pressing operation of the button 5. This releases the fixed state of the arm portion 2b of the baffle 2, whereby the baffle 2 is caused by the torsion spring 3 The driving force is automatically rotated to the closed position. Therefore, the pressing operation on the operating portion 5a of the button 5 only needs a stroke amount for releasing the fixed state of the shutter 2, so that the pressing operation is performed. In addition, in order to operate the button 5, only one thrust equivalent to 10 degrees of the coil spring § 2 is required, and therefore, the pressurizing operation can be performed by using a small force of one finger, thereby enhancing the protection. The operability of the device. When the baffle 2 reaches the closed position in the aforementioned manner, as previously described, the magnet cymbal is engaged with the locking mechanism 4, thereby locking the baffle 2. Further, when the magnetic key is utilized ΜΚ releasing the locked state of the shutter 2 locked by the locking mechanism 4, when the locking mechanism 4 is rotated, the shutter 2 also rotates against the urging force of the torsion spring 3. Since the arm portion 2b The cam action generated when the tapered portion 2ba contacts the arm portion 5b, The arm portion 2b of the baffle 2 can be smoothly fixed to the arm portion 2b of the button 5, whereby the baffle 2 can be held in the open position. Further, according to this embodiment, the edge of the baffle 2 is The portion 2d (lower surface side) is formed in a rounded shape. The edge portion 2d is moved when the shutter 2 is inserted into the keyhole & of the cylinder lock S with a key (a start key) When the closed position is as shown in Figures 5 and 6, the portion of the shutter 2 that is in contact with the key. With this configuration, even when the button 5 (operating mechanism) is erroneously operated, 14 200936861 becomes the key insertion. When the shutter 2 is in the keyhole Sa and the shutter 2 is thus moved to the closed position and the key is held in the shutter 2, the key can be easily withdrawn.

When the extended portion 5c is pressurized, the extended portion 5c can also be moved downward. Below the extended portion 5c, a micro switch 6 is provided. When the button 5 is pressurized and the extension portion 5c is moved downward, the front end of the extension portion 5c is pressed against the operation portion 6a of the microswitch 6, whereby the microswitch 6 can be activated. With this configuration, for example, an illumination mechanism respectively provided on 10 vehicles of one two-wheeled vehicle can be activated, whereby the keyhole sa can be illuminated. According to the foregoing embodiment, since the button 5 (operating mechanism) capable of releasing the fixed state of the shutter 2 by pressurizing the operating portion 5a is provided, and since the shutter 2 and the locking mechanism 4 are also integrally formed, Therefore, when compared with a device in which the baffle 2 and the locking mechanism 4 are respectively formed, the structure of the present invention can be simplified and the manufacturing cost of the device can be reduced while maintaining the operability of the device for protecting the cylinder lock 15 With size. The pushing mechanism for pushing the shutter 2 from the open position to the closed position is constituted by the torsion spring 3 disposed on the machine 20 different from the rotating shaft of the shutter 2, so that when the towel is twisted When the structure of the hinge of the seesaw 2 (i.e., the 'magnetic lock projection part lab') is compared with the thicker shot of the job, the torsion spring 3 can also be replaced when there is a job board 2 Thereby, the maintenance convenience of the device can be increased. Although the cylinder lock protection device of this embodiment has been described herein, the present invention is not limited thereto, and for example, in addition to the button 5, it is also possible to use = 15 200936861 to fix only the baffle at the open position and include A further operating mechanism (e.g., a sliding or a rotary operating mechanism) disposed on the housing and projecting the operating portion of the projection, whereby the fixed state of the shutter can be released by operating the operating portion. Further, although a magnetic lock for fixing the magnet cartridge to the lock mechanism 4 is used as the lock mechanism in the embodiment, other types of lock mechanisms may be used. Further, in addition to the torsion spring, other types of pushing mechanisms that push the shutter from the open position to the closed position may be used. 10 [Industrial Applicability] The present invention is applicable to a cylinder lock protection device including a baffle, and the baffle can be rotated in a casing and thus can be moved between a closed position and an open position to open A keyhole is closed, and in the cylinder lock protector, the baffle is integrally formed 15 with a locking mechanism for locking the baffle as a single member. Further, the present invention can be similarly applied to a device having a different shape from the foregoing device or a device having an additional function attached thereto as long as it has the aforementioned structure.
