Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a lock baffle and a lock with the lock baffle. Background Art

[0002] At present, each unit movable panel of the train platform door (fixed door movable panel / sliding door movable panel / emergency door movable panel) is provided with a locking point, and locking is achieved by the cooperation of a lock equipped with a hook-pull type steel bolt and a baffle, that is, the baffle is fixed on one side of the platform door lintel, and the lock is fixed on one side of the movable panel. The lock is operated by a key to rotate the steel bolt so that the steel bolt is hooked on the baffle to limit the lateral movement of the steel bolt to achieve locking. When unlocking is required, the key is used to turn the lock core to drive the steel bolt to rotate a certain angle, and the steel bolt and the baffle are disengaged, and the lateral movement of the steel bolt is no longer restricted to achieve unlocking. Based on the considerations of safety and convenience of use, the lock is usually designed with a self-resetting locking function, that is, when the lock core is screwed in without a key, the rotated steel bolt can be restored to its state before rotation under the action of the lock core spring force.

[0003] However, due to the long length of the movable panels in the platform door area, each unit movable panel is usually provided with at least two locking points. When it needs to be opened, two people are often required to simultaneously unlock the two locking points to open the movable panel. When a single person operates, it is often necessary to perform irregular operations after unlocking one locking point to limit the self-resetting of the lock. For example, after unlocking one locking point, the movable panel is pulled outward to slightly deform, so that the movable panel and the lintel beam at the unlocking locking point are separated by a greater distance. If necessary, hard objects are inserted to keep the movable panel slightly open to prevent the lock from automatically locking. Then, another locking point is unlocked to open the movable panel. The above operations are more troublesome and can easily cause damage to the lock, affecting the service life of the lock. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a lock baffle which can not only realize locking but also limit the self-reset of the lock after unlocking so as to maintain the unlocking function, and a lock with the lock baffle.

[0012] A further technical solution is as follows: the lock baffle further comprises a limiting rod, and the limiting rod is located on the fixed baffle and above the rotating shaft.

[0013] Its further technical solution is: the fixed baffle includes a third mounting plate and a fourth mounting plate bent outward from the upper end of one side of the third mounting plate, the upper end of the movable baffle can be rotatably connected to the fourth mounting plate, and the middle and lower part of this side of the third mounting plate is provided for the hook-type steel bolt of the lock when the lock is locked.

[0014] A further technical solution is as follows: a lower end portion of the third mounting plate extends outward to form an outer edge, and the outer edge and the fourth mounting plate are located on the same side of the third mounting plate.

[0015] Its further technical solution is: the movable baffle includes a first mounting plate and a movable plate extending downward from one side of the first mounting plate, the first mounting plate can be rotatably connected to the fourth mounting plate, the movable plate is located on one side of the third mounting plate, and the baffle is formed by bending outward from the inner side of the movable plate.

[0016] In order to solve the above technical problems, according to another aspect of the utility model, a lock is disclosed, including a lock body and the above-mentioned lock baffle, the lock body including a shell, a lock core driving mechanism located in the shell, an elastic member and a hook-pull type steel bolt connected to the lock core driving mechanism, the lock core driving mechanism is locked under the action of an unlocking key so that the hook-pull type steel bolt rotates, and when locking, pushes away the movable baffle located on one side of the fixed baffle and hooks on the fixed baffle of the lock baffle to achieve locking or detaches from the fixed baffle to achieve unlocking, and the hook-pull type steel bolt is connected to the elastic member so that it can be reset to the lock by the elastic member when there is no unlocking key after unlocking, and before resetting the lock, the blocking part of the movable baffle blocks the hook-pull type steel bolt to achieve unlocking and retention.

[0017] The beneficial technical effect of the utility model is as follows: compared with the prior art, the lock baffle of the utility model comprises a fixed baffle for hooking the hook-pull type steel bolt of the lock and a movable baffle located on one side of the baffle, the upper end of the movable baffle is rotatably connected with the fixed baffle, wherein the lower part is bent outward to form a blocking portion that cooperates with the hook-pull type steel bolt, and when the lock baffle is applied to a lock with a hook-pull type steel bolt and the lock is locked, the blocking portion is pushed by the hook-pull type steel bolt to move in a direction away from the fixed baffle without affecting the locking function, the hook-pull steel bolt is blocked by the fixed baffle and continues to rotate until the hook-pull steel bolt is hooked on the fixed baffle to achieve locking; and when in use When the key is used to unlock the door, the hook-pull steel bolt rotates in the opposite direction and leaves the fixed baffle. The hook-pull steel bolt is no longer in contact with the movable baffle, and the movable baffle is no longer subjected to the thrust and returns to the side of the fixed baffle. When the lock resets itself, the blocking part blocks the hook-pull steel bolt, limiting the self-resetting locking of the lock, thereby realizing the unlocking retention function. It can be seen that the lock baffle of the utility model can be applied to the field of doors, windows, and cabinets, and can be used as a normal locking baffle in conjunction with the lock. At the same time, an unlocking retention function is also provided. On the movable panel of the platform door with multiple locking points, there is no need for multiple people to operate and unlock at the same time. It can be unlocked one by one, and the movable panel can be opened by one person, reducing the demand for the number of operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0031] The lock baffle in the utility model can be applied to many technical fields. For example, it can be used on the movable panel of the platform door to realize locking and unlocking of the movable panel. It can also be used in scenes such as doors, windows, cabinets, etc. where locking of movable parts is required. Its scope of use is not limited.

[0032] Reference Figures 1 to 8 , Figures 1 to 8The first embodiment of the lock baffle 100 of the utility model is shown. The lock baffle 100 of the utility model is applied to a lock with a hook-pull type steel bolt 200 to cooperate with the hook-pull type steel bolt 200 to achieve locking and unlocking, and the lock has a self-resetting function. In the embodiment shown in the accompanying drawings, the lock baffle 100 includes a fixed baffle 10 and a movable baffle 20, wherein the fixed baffle 10 is used for hooking the hook-pull type steel bolt 200 of the lock; the movable baffle 20 is located on one side of the fixed baffle 10, and the upper end of the movable baffle 20 can be rotatably connected to the fixed baffle 10, and the middle and lower parts of the movable baffle 20 are bent outward to form a blocking portion 21 to cooperate with the hook-pull type steel bolt 200. When the lock is locked, the blocking portion 21 causes the movable baffle 20 to rotate in a direction away from the fixed baffle 10 under the thrust of the hook-pull type steel bolt 200, and resets after the lock is unlocked, and blocks the hook-pull type steel bolt 200 when the lock is in a self-resetting locked state. Based on the above design, when the lock baffle 100 is applied to a lock with a hook-pull steel bolt 200, and the lock is locked, the hook-pull steel bolt 200 pushes the blocking portion 21 to move in the direction away from the fixed baffle 10, thereby driving the movable baffle 20 to rotate in the direction away from the fixed baffle 10, and the movable baffle 20 is away from the fixed baffle 10, so that the hook-pull steel bolt 200 is hooked on the fixed baffle 10 to achieve locking. When the key is used to rotate and unlock, the hook-pull steel bolt 200 rotates in the opposite direction and leaves the fixed baffle 10. The hook-pull steel bolt 200 is no longer in contact with the movable baffle 20, and the movable baffle 20 is no longer subjected to the thrust, and it returns to the side of the fixed baffle 10. When the lock resets itself, the blocking portion 21 blocks the hook-pull steel bolt 200, restricting the self-resetting locking of the lock, thereby achieving the unlocking function.

[0033] In some embodiments, the upper end of the movable baffle 20 is connected to the fixed baffle 10 via a rotating shaft 30, and the movable baffle 20 can rotate around the rotating shaft 30. Based on this design, the movable baffle 20 can rotate around the rotating shaft 30 under the action of the hook-type steel bolt 200 to move away from the fixed baffle 10, and can also rotate around the rotating shaft 30 in the opposite direction under the action of gravity to return to the initial position, that is, return to the side of the fixed baffle 10.

[0034] Continue to refer to Figures 1 to 4In some embodiments, the fixed baffle 10 includes a third mounting plate 12 and a fourth mounting plate 13 formed by bending outward from the inner upper end of the third mounting plate 12, the upper end of the movable baffle 20 is rotatably connected to the fourth mounting plate 13 through the rotating shaft 30, and the middle and lower part of the third mounting plate 12 on this side is provided for the hook-type steel bolt 200 of the lock to be hooked when the lock is locked. Further, in this embodiment, the lower end of the third mounting plate 12 extends outward to form an outer edge 11, the outer edge 11 and the fourth mounting plate 13 are located on the same side of the third mounting plate 12, and the outer edge 11 below the third mounting plate 12 is provided with a mounting hole 14, so that the lock baffle 100 can be fixed to the fixed frame such as the platform door lintel beam through the mounting hole 14 and the screw. Based on the above design, the outer edge 11 can limit the rotation angle of the movable baffle 20.

[0035] In some embodiments, the movable baffle 20 includes a first mounting plate 22 and a movable plate 23 extending downward from one side of the first mounting plate 22, the first mounting plate 22 can be rotatably connected to the fourth mounting plate 13, the movable plate 23 is located on one side of the third mounting plate 12, and the stopper 21 is formed by bending outward from the inner side of the movable plate 23; preferably, in this embodiment, the bending angle a of the stopper 21 bending outward from the inner side of the movable plate 23 is 25° to 45°. Based on the above design, the stopper 21 is tilted outward relative to the movable plate 23, and the bending angle is set to 25° to 45°, which does not affect the normal opening of the movable panel, and when the lock is self-reset, it blocks the hook-pull type steel bolt 200 to prevent the movable baffle 20 from rotating due to accidents such as vibration, thereby disengaging from the hook-pull type steel bolt 200 and causing the lock to reset.

[0036] Furthermore, in this embodiment, the lock baffle 100 further includes a limiting rod 40, which is located on the fixed baffle 10 and above the rotating shaft 30. Based on the design of the limiting rod 40, the rotation angle of the movable baffle 20 can also be limited.

[0037] It can be understood that if the hook-pull type steel bolt 200 has a notch 201, when the lock baffle 100 of the utility model is used in conjunction with the lock having the hook-pull type steel bolt 200, the initial state is that the movable panel is closed. At this time, the state of the hook-pull type steel bolt 200 and the lock baffle 100 is as follows: Figure 6As shown, the hook-pull type steel bolt 200 of the lock is hooked on the fixed baffle 10 in the lock baffle 100, and the notch 201 is clamped on the third mounting plate 12 of the fixed baffle 10, and the movable plate 23 of the movable baffle 20 is away from the third mounting plate 12. When the movable panel needs to be opened, the key is used to turn the lock core to drive the hook-pull type steel bolt 200 to rotate, and the notch 201 of the hook-pull type steel bolt 200 is separated from the third mounting plate 12 to achieve unlocking. At this time, the movable plate 23 of the movable baffle 20 is reset under the action of gravity and returns to the side of the third mounting plate 12. The key is pulled out, and the blocking portion 21 can block the hook-pull type steel bolt 200 when the lock is reset (as shown in FIG. Figure 7 and Figure 8 As shown in the figure, the notch 201 of the hook-pull steel bolt 200 is restricted from entering the fixed baffle 10 and maintaining this state, thereby realizing unlocking and holding. When the other lock point is also unlocked and in the unlocking and holding state, the user can push the movable panel, and the hook-pull steel bolt 200 moves with the movable panel and separates from the stopper 21, thereby opening the movable panel; when it is necessary to close the lock, the movable panel returns to its original position, and the hook-pull steel bolt 200 pushes the stopper 21 to move away from the fixed baffle 10, thereby driving the first securing member 10 to move in a direction away from the fixed baffle 10. The mounting plate 22 rotates around the rotating shaft 30 and rotates in the direction away from the fixed baffle 10, so that the movable plate 23 is away from the fixed baffle 10, giving way to the third mounting plate 12 of the fixed baffle 10, and the notch 201 of the hook-pull type steel bolt 200 is clamped on the third mounting plate 12, that is, in the process of the hook-pull type steel bolt 200 pushing the movable baffle 20 to move, the movable baffle 20 and the hook-pull type steel bolt 200 remain in contact, and the movable baffle 20 is always located on the outside or above the hook-pull type steel bolt 200 and cannot be reset, thereby achieving locking.

[0038] Reference Figures 9 to 11 , Figures 9 to 11The second embodiment of the lock baffle 100 of the utility model is shown. The difference between this embodiment and the first embodiment is that a reset torsion spring 50 is added, and a limit rod is not provided. The other structures are the same or similar. In this embodiment, the lock baffle 100 also includes a reset torsion spring 50, and the reset torsion spring 50 is sleeved on the rotating shaft 30, and one end of the reset torsion spring 50 is connected to the fixed baffle 10, and the other end is connected to the upper end of the movable baffle 20. Based on the above design, when the lock baffle 100 is applied to a lock with a hook-pull type steel bolt 200, and the lock is in a rotating locked state, the hook-pull type steel bolt 200 rotates, and in this process, the blocking portion 21 is pushed to move in a direction away from the fixed baffle 10, thereby driving the movable baffle 20 to rotate in a direction away from the fixed baffle 10, and the movable baffle 20 is away from the fixed baffle 10, so that the hook-pull type steel bolt 200 is hooked on the fixed baffle 10 to achieve locking. In this process, the reset torsion spring 50 is twisted. It can be understood that when the reset torsion spring 50 is twisted, Due to the limitation of rotation, the limit rod 40 may not be provided in this embodiment; when the key is used to rotate and unlock, the hook-pull steel bolt 200 rotates in the opposite direction and leaves the fixed baffle 10, the hook-pull steel bolt 200 no longer abuts against the movable baffle 20, and the reset torsion spring 50 returns to its original position. The movable baffle 20 is reset under the action of the reset torsion spring 50 and returns to the side of the fixed baffle 10. The lock baffle 100 of this embodiment is also when the lock is self-reset. The blocking part 21 on the movable baffle 20 can block the hook-pull steel bolt 200, thereby limiting the self-reset locking of the lock, thereby maintaining the unlocking function.

[0039] Specifically, Fig. 9 and Fig.10 As shown, in this embodiment, a first elongated hole 131 is provided on the fourth mounting plate 13 of the fixed baffle 10 and is located obliquely above the rotating shaft 30, and a second elongated hole 221 is provided on the first mounting plate 22 of the movable baffle 20 and is located next to the rotating shaft 30, and one end of the reset torsion spring 50 passes through the first elongated hole 131, and the other end passes through the second elongated hole 221.

[0040] In summary, it can be seen that the lock baffle 100 of the utility model can be used in conjunction with the lock to achieve normal locking, and can prevent the lock from resetting to lock after being unlocked with the key, that is, the unlocking and holding function, which is a beneficial extension of the baffle with only a locking function. The lock baffle 100 of the utility model adopts a modular design and can be used as a whole. It can increase the function by simply replacing the baffle with only a locking function by utilizing the existing installation interface, and there is no need to change the fixed frame or other structures on the lock. In addition, since the lock baffle 100 of the utility model has the unlocking and holding function, it can be unlocked in sequence on the movable panel of the platform door with multiple locking points, and a single person can open the movable panel, reducing the demand for the number of operating personnel.

[0041] Understandably, the utility model can also provide a lock, the lock includes a lock body and the lock baffle 100 described in the first embodiment / second embodiment, the lock body includes a shell, a lock core drive mechanism located in the shell, an elastic member, and a hook-pull type steel bolt 200 connected to the lock core drive mechanism, the lock core drive mechanism works under the action of the unlocking key to make the hook-pull type steel bolt 200 rotate, hooked on the fixed baffle 10 of the lock baffle 100 to achieve locking or detached from the fixed baffle 10 to achieve unlocking, and the hook-pull type steel bolt 200 is connected to the elastic member, so that when there is no unlocking key after unlocking, the elastic member is reset to achieve reset locking, and when resetting the lock, the blocking portion 21 of the movable baffle 20 blocks the hook-pull type steel bolt 200. It can be seen that the lock with the lock baffle 100 of the utility model can not only achieve locking and meet the closing of the movable panel, but also prevent the lock from self-resetting and locking when the key is used to unlock, so as to maintain the unlocking function.

[0042] The above-mentioned preferred implementation modes should be regarded as examples of the implementation modes of the utility model scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the utility model scheme or made based on it should be regarded as within the scope of protection of this patent.
