Description

Technical Field

[0001] The present invention relates to the technical field of lock bodies, and in particular to an intelligent cabinet lock. Background Art

[0002] A lock refers to a device that serves a sealing function, which includes a lock, a key and its accessories. In addition to being opened with a key, a lock can also be opened with light, electricity, magnetism, sound and fingerprint commands. A lock is not only a protective device, but also has the functions of "management" and "decoration". Smart locks are widely used in various occasions, and their safety and convenience are well received by the public. Usually, in order to reduce power consumption or enhance security, smart locks will design special trigger mechanisms to wake up the smart locks.

[0003] For example, a smart cabinet lock with a protection wake-up switch and publication number CN215485340U includes: a lock body; a storage slot provided on the lock body; a handle movably connected to the lock body and used to open or close the storage slot; a wake-up switch provided on the lock body; and a trigger column provided on the handle and cooperating with the wake-up switch, wherein the trigger column is used to trigger the wake-up switch to wake up the lock body; the handle is stored in the storage slot to protect the wake-up switch and the trigger column.

[0004] The above patent presses down the handle to move the trigger column toward the wake-up switch, and then the trigger column squeezes the wake-up switch to achieve wake-up. However, the above patent does not restrict the movement of the handle in the storage slot, so outsiders can easily trigger the wake-up switch, and can also violently squeeze the handle to indirectly destroy the wake-up switch through the trigger column, and the wake-up switch cannot be protected. Summary of the invention

[0005] The present invention is intended to provide an intelligent cabinet lock to solve the problem in the prior art that the handle movement is not restricted, resulting in limited protection of the handle for the wake-up switch.

[0006] In order to solve the above problems, the present invention provides the following technical solutions: an intelligent cabinet lock comprises a lock body shell, the lock body is provided with a lock slot, a wake-up switch and a storage slot, the lock slot is matched with a key, the storage slot is slidably connected with a handle, and the handle is provided with a trigger column matching with the wake-up switch; the handle is provided with a keyhole, the lock slot and the keyhole are opposite, and a limiting hole is also provided at the bottom of the handle, a driving chamber is provided at the bottom of the lock body shell, the driving chamber is vertically slidably connected to the limiting column extending into the limiting hole, the driving chamber is also vertically slidably connected with a wedge block located between the lock slot and the keyhole, the key is fixedly sleeved with an annular block for pushing the wedge block to move downward, and the driving chamber is rotatably connected with a driving gear and a connecting gear that are meshed with each other, the wedge block is fixedly connected with a first rack meshed with the connecting gear, the limiting column is fixedly connected with a second rack meshed with the driving gear, and a first spring is also provided between the limiting column and the driving chamber.

[0007] Working principle of the present invention: Based on the existing technology, this scheme adds a limit column, and the first spring lifts the limit column. At this time, the limit column is inserted into the limit hole at the bottom of the handle, and the handle and the storage slot are slidably connected. The handle is restricted by the limit column, which can limit the movement of the handle, thereby preventing the trigger column from triggering the wake-up switch.

[0008] When it is necessary to open the cabinet lock, the key is aligned with the lock slot and inserted into the keyhole. Since the key is fixedly sleeved with the limit block, and the driving chamber is vertically slidably connected with a wedge block located between the lock slot and the keyhole, in the process of the key driving the limit block to move, the limit block squeezes the wedge block downward, and the wedge block moves downward to drive the first rack to move; and the driving chamber is rotationally connected with a driving gear and a connecting gear that mesh with each other. The first rack is meshed with the connecting gear, and the first rack drives the connecting gear to rotate in the opposite direction, and the connecting gear drives the driving gear to rotate forward, and the second rack is meshed with the driving gear. The second rack is fixedly connected to the limit column, and the driving gear rotates to drive the second rack to move downward, and the second rack drives the limit column to move toward the driving chamber, the bottom of the limit column compresses the first spring, and the top of the limit column disengages from the limit hole, thereby releasing the restriction of the handle, and the handle can be pressed down to make the trigger column press the wake-up switch to turn on.

[0009] Beneficial effects of the present invention: This solution locks the handle by setting an additional limit column, so that outsiders cannot trigger the wake-up switch, and cannot press the handle violently to indirectly destroy the wake-up switch. The handle can only be released using a key used in conjunction with the lock slot.

[0010] Furthermore, the key hole is hinged with a key cover, which can cover the key hole to prevent foreign objects from entering the key hole.

[0011] Furthermore, a second spring is provided between the first rack and the driving chamber. Similarly, the second spring serves as a support member of the first rack and plays a role in supporting the wedge block.

[0012] Furthermore, the top of the limiting column is a pointed end, and the setting of the pointed end facilitates the limiting column to be inserted into the limiting hole.

[0013] Furthermore, a return spring is provided between the handle and the lock body shell. When the handle is squeezed, the return spring is compressed, and when the handle is released, the return spring returns to the initial position.

[0014] Furthermore, an inspection port is provided at the bottom of the lock body shell, through which the driving gear and the connecting gear can be inspected. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is further described in detail through specific implementation methods:

[0020] The figure marks in the drawings of the specification include: lock slot 1, lock body shell 2, reset spring 3, trigger column 4, wake-up switch 5, key hole 6, key 7, drive chamber 8, wedge block 9, second spring 10, first rack 11, connecting gear 12, drive gear 13, first spring 14, limit column 15, second rack 16, limit hole 17, limit block 18, handle 19.

[0021] Embodiment: A smart cabinet lock, such as Figure 1 and Figure 3 As shown, it includes a lock body shell 2, which is made of metal material. A lock slot 1 and a wake-up switch 5 are fixedly arranged on the left side of the lock body shell 2, and a key 7 is matched with the lock slot 1, and a ring-shaped limit block 18 is fixedly sleeved on the key 7; a storage slot is arranged on the right side of the lock body, and a handle 19 sliding toward the wake-up switch 5 is slidably connected to the storage slot, and a reset spring 3 is fixedly connected between the handle 19 and the lock body shell 2, and the handle 19 is provided with a key hole 6 and a trigger column 4 used in conjunction with the wake-up switch 5, and a limit hole 17 is also arranged at the bottom of the handle 19.

[0022] A driving chamber 8 is also provided at the bottom of the lock body shell 2, and the driving chamber 8 is rotatably connected to a driving gear 13 and a connecting gear 12 that mesh with each other. A wedge block 9 located between the lock slot 1 and the key hole 6 is vertically slid on the left side of the driving chamber 8, and a limiting column 15 is vertically slid and extended into the limiting hole 17 on the right side of the driving chamber 8, wherein the wedge block 9 is fixedly connected to a first rack 11 that meshes with the connecting gear 12, and the limiting column 15 is fixedly connected to a second rack 16 that is connected to the driving gear 13, and a second spring 10 is fixedly connected between the bottom of the wedge block 9 and the bottom of the driving chamber 8, and a first spring 14 is fixedly connected to the limiting column 15 and the bottom of the driving chamber 8.

[0023] In this solution, a limit column 15 is added on the basis of the prior art. The first spring 14 lifts up the limit column 15. At this time, the limit column 15 is inserted into the limit hole 17 at the bottom of the handle 19. The handle 19 and the storage slot are slidably connected. The handle 19 is restricted by the limit column 15, which can limit the sliding of the handle 19, thereby preventing the trigger column 4 from triggering the wake-up switch 5.

[0024] like Figure 2 and Figure 4 As shown, when the cabinet lock needs to be opened, the key 7 is aligned with the lock slot 1 and inserted through the key hole 6. Since the key 7 is fixedly sleeved with the limit block 18, and the driving chamber 8 is vertically slidably connected with the wedge block 9 located between the lock slot 1 and the key hole 6, during the process of the limit block 18 driven by the key 7 to move, the limit block 18 presses the wedge block 9 downward, and the wedge block 9 moves downward to drive the first rack 11 to move; and the driving chamber 8 is rotatably connected with the driving gear 13 and the connecting gear 12 that mesh with each other, and the first rack 11 and the connecting gear 12 mesh, then the first rack 11 drives the connecting gear 12 to mesh with each other. The connecting gear 12 rotates in the opposite direction, and the connecting gear 12 drives the driving gear 13 to rotate forward, and the second rack 16 meshes with the driving gear 13. The second rack 16 and the limiting column 15 are fixedly connected. After the driving gear 13 rotates, it drives the second rack 16 to move downward, and the second rack 16 drives the limiting column 15 to move toward the driving chamber 8. The bottom of the limiting column 15 compresses the first spring 14, and the top of the limiting column 15 disengages from the limiting hole 17, thereby releasing the restriction of the handle 19. The handle 19 can then be moved to allow the trigger column 4 to press the wake-up switch 5 to turn on.

[0025] This solution locks the handle 19 by providing an additional limit column 15, so that outsiders cannot trigger the wake-up switch 5, and cannot forcibly press the handle 19 to indirectly destroy the wake-up switch 5. The handle 19 can only be released by using the key 7 used in conjunction with the lock slot 1. It is particularly suitable for cabinet doors that require a mechanical lock and an electronic lock to cooperate and a double unlocking method to open.

[0026] It should be pointed out that for those skilled in the art, multiple variations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
