Description

Technical Field

[0001] The present application relates to the field of lockers, and in particular to a locker lock capable of improving the safety of storing items. Background Art

[0002] Lockers are used in all areas of life to facilitate the storage of people's personal belongings or mail items. Lockers have multiple doors, each of which is equipped with a lock. When storing and retrieving items, each door must be opened and closed once. Therefore, locks are one of the most frequently used components of lockers. At the same time, these locks are also the most numerous components on lockers. Therefore, for lockers, the possibility of problems with locks is relatively high, and the requirements for their reliability are also high.

[0003] In the related art, the above-mentioned locks generally adopt the form of electric unlocking. Usually, a lock bolt set on the cabinet door pushes the lock into a locked state when the door is closed. When the control part confirms that the lock needs to be unlocked, the electromagnet is driven to attract and drag the lock component, so that the lock bolt pops out to unlock.

[0004] However, the prior art only uses one micro switch to detect the unlocking status, and there is no data for comparison, so that the system may consider the state to be locked in the event of a switch failure. Due to the frequent operation of opening and closing the door, the probability of failure of the switch is relatively high. Such misjudgments occur from time to time, affecting the safe storage of customers' belongings, and needs to be improved. Utility Model Content

[0005] In order to reduce the occurrence of misjudgment, the present application provides a locker lock that can improve the safety of item storage.

[0006] The present application provides a locker lock that can improve the safety of storing items, which adopts the following technical solutions:

[0007] A locker lock capable of improving the safety of storing articles, comprising a shell, a lock buckle hinged on the shell, and a slider slidably connected to the shell, the slider being used to push the lock buckle to flip so that the lock buckle switches between a locked state and an unlocked state, the shell being provided with a control component, the control component being used to drive the slider to move, the slider being provided with a guide surface 1 and a guide surface 2, the shell being provided with a detection switch 1 and a detection switch 2, the detection switch 1 and the detection switch 2 being located on a side of the slider close to the guide surface 1, the guide surface 1 and the guide surface 2 being respectively located on a side of the detection switch 1 and the detection switch 2 being away from each other, and the guide surface 2 being located on a side of the detection switch 2 close to the lock buckle, and the distance between the guide surface 1 and the guide surface 2 gradually increases in a direction away from the slider;

[0008] When the guide surface one is pressed against the detection switch one, the detection switch one is used to feed back a signal to the background monitoring to display that the lock is in an unlocked state. When the guide surface two is pressed against the detection switch two, the detection switch two is used to feed back a signal to the background monitoring to display that the lock is in a locked state.

[0009] By adopting the above technical solution, the control component drives the slider to move, so that the guide surface one is pressed against the detection switch one, and the detection switch one feeds back a signal to the background monitoring to show that the lock is in the unlocked state. When the lock needs to be locked, the control component drives the slider to move in the opposite direction, so that the guide surface two is pressed against the detection switch two, and the detection switch two feeds back a signal to the background monitoring to show that the lock is in the locked state. By comparing the signal feedback obtained by the detection switch one and the detection switch two with each other, an accurate lock state can be obtained. Even if one of the detection switches fails, the lock state can be judged based on the remaining detection switches to achieve switching between the locked state and the unlocked state, thereby reducing the situation where the locker door is unlocked due to a failure and improving the safety of item storage.

[0010] Optionally, the control component includes a worm rotatably connected to the housing, a transmission gear set, a driven gear and a driving member arranged on the housing, the driving member drives the worm to rotate, the worm drives the driven gear to rotate through the transmission gear set, the slider is provided with a tooth surface, and the tooth surface is meshed with the driven gear.

[0011] By adopting the above technical solution, the driving member drives the worm to rotate, the worm drives the driven gear to rotate through the transmission gear set, and the driven gear drives the slider to move through the meshing cooperation with the tooth surface, which can reduce the volume of each component of the control assembly, thereby facilitating full use of the accommodation space in the shell and reducing the volume of the locker lock.

[0012] Optionally, the slider includes a block body 1 slidably connected to the shell, a block body 2 slidably connected to the block body 1, and an elastic member arranged on the block body 1, the sliding direction of the block body 2 is parallel to the sliding direction of the block body 1, the tooth surface, the guide surface 1 and the guide surface 2 are all arranged on the block body 2, the lock includes a main body hinged on the shell and a limiting shaft arranged on the main body, a clearance groove is provided on the block body 1, the limiting shaft is located in the clearance groove, a limiting groove is provided on the block body 1, a through hole is provided on the block body 2, and the elastic member is located in the limiting groove and passes through the through hole.

[0013] By adopting the above technical solution, when the driven gear drives block two to move close to the lock buckle through the meshing cooperation with the tooth surface, block two squeezes the elastic part, and the elastic part presses against the inner wall of the limiting groove to drive block one to move. Block one presses against the limiting shaft through the inner wall of the giving groove to push the body to flip and realize unlocking.

[0014] When the driven gear drives block two to move away from the lock buckle through the meshing cooperation with the tooth surface, if the lock buckle is stuck, block two presses against the elastic member to cause the elastic member to deform so that block two can continue to move, so that the output shaft of the driving member can keep rotating, reducing the situation where the output shaft of the driving member is damaged by the reaction force due to the lock buckle being stuck, which is beneficial to extending the service life of the driving member. At this time, the lock buckle can be released from the stuck state by tapping the shell, and then the elastic member is reset to drive block one to push the limit shaft, so that the body flips over and switches to the locked state.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. By comparing the signal feedbacks obtained by detection switch 1 and detection switch 2, the accurate lock status can be obtained. Even if one of the detection switches fails, the lock status can be judged based on the remaining detection switches to switch between the locked and unlocked states, reducing the situation where the locker door is unlocked due to failure and improving the safety of item storage;

[0017] 2. The driving member drives the worm to rotate, and the worm drives the driven gear to rotate through the transmission gear set. The driven gear drives the slider to move through the meshing cooperation with the tooth surface, which can reduce the volume of each component of the control assembly, thereby making full use of the accommodation space in the shell and reducing the volume of the locker lock;

[0018] 3. When the lock is stuck, block two presses against the elastic member to deform the elastic member so that block two can continue to move, thereby allowing the output shaft of the driving member to keep rotating, reducing the possibility that the output shaft of the driving member is damaged by the reaction force due to the lock being stuck, which is beneficial to extending the service life of the driving member.

In this embodiment, the detection switch 10 and the detection switch 2 11 are both miniature detection switches.

[0035] When the guide surface 8 is pressed against the detection switch 10, the detection switch 10 is used to feed back a signal to the background monitoring to show that the lock buckle 2 is in an unlocked state. When the guide surface 2 9 is pressed against the detection switch 2 11, the detection switch 2 11 is used to feed back a signal to the background monitoring to show that the lock buckle 2 is in a locked state.

[0036] The implementation principle of a locker lock that can improve the storage safety of items in the embodiment of the present application is as follows:

[0037] When the driven gear 53 drives the connecting part 321 to move closer to the lock buckle 2 through the meshing cooperation with the tooth surface 12, the sliding part 322 squeezes the elastic part 33, and the elastic part 33 presses against the inner wall of the limiting groove 312 to drive the block 31 to move. The block 31 presses against the limiting shaft 22 through the inner wall of the giving groove 311 to push the main body 21 to flip. At this time, the guide surface 8 presses against the detection switch 10, and the detection switch 10 feeds back the signal to the background monitoring to show that the lock buckle 2 is in the unlocked state.

[0038] When it is necessary to lock the door, the driven gear 53 is controlled to drive the connecting part 321 to move away from the lock buckle 2, so that the detection switch 2 11 is inserted into the groove 2 7, until the guide surface 2 9 is pressed against the detection switch 2 11. The detection switch 2 11 feeds back a signal to the background monitoring to show that the lock buckle 2 is in a locked state. The signal feedback obtained by the detection switch 1 10 and the detection switch 2 11 are used as a reference to obtain an accurate lock state. Even if one of the detection switches fails, the lock state can be judged based on the remaining detection switches to achieve switching between the locked state and the unlocked state, thereby reducing the situation where the locker door is unlocked due to a failure and improving the safety of item storage.

[0039] If the lock buckle 2 is stuck, the sliding portion 322 presses against the elastic member 33 to deform the elastic member 33 so that the connecting portion 321 continues to move, thereby allowing the output shaft of the driving member 54 to keep rotating, thereby reducing the situation in which the output shaft of the driving member 54 is damaged by the reaction force due to the lock buckle 2 being stuck, which is beneficial to extending the service life of the driving member 54. At this time, the lock buckle 2 can be released from the stuck state by tapping the shell 1, and then the elastic member 33 is reset to drive the block 1 31 to push the limit shaft 22, so that the main body 21 flips over and switches to the locked state.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
