AI Technical Summary
The existing motor cabinet locks lack anti-counterfeiting features, making it difficult to detect safety hazards in a timely manner.
By combining the locking component with the push block body, when the hook body is pushed alone, the locking component cannot move downwards because it is pressed down by the push block body below. This causes the hook body to be blocked by the protruding surface of the locking component when it is pushed in, thus achieving the anti-false locking function.
It effectively prevents counterfeit locks, improves the security of motor cabinet locks, and simplifies the forming process of sheet metal lower shell.

[0001] This utility model relates to the field of cabinet lock technology, and in particular to a novel motor cabinet lock. Background Technology
[0002] Locks are devices that serve a sealing function, including locks, keys, and their accessories. Generally, they are defined as "sealing devices that can only be opened with a key." Besides keys, locks can also be opened using light, electricity, magnetism, sound, and fingerprint signals. Locks are not only protective devices but also serve management and decorative purposes. With the development of technology, electronic locks have become increasingly popular.
[0003] However, most motor cabinet locks on the market do not have anti-counterfeiting features on the inside. If a counterfeit lock is not detected in time, it can easily cause safety hazards, making the applicability of motor cabinet locks relatively poor. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of motor cabinet lock. By combining the locking component and the push block body, when the hook body is pushed alone, the locking component cannot move downward because it is pressed down by the push block body below. As a result, when the hook body is pushed in, the protruding surface of the locking component blocks it and cannot lock, thereby achieving the function of preventing false lock.
[0005] To solve the above technical problems, this utility model provides the following technical solution: A novel motor cabinet lock, comprising a lower shell, a lock body, an inner cover, and an upper shell. The lock body is composed of a lever detection switch, a drive motor, a motor cam, a pull rod, a locking component, an anti-disengagement torsion spring, a lever body, a hook body, a hook torsion spring, a push block body, a push block spring, a push rod body, a push rod spring, and a PCBA board. A push rod spring is installed inside the PCBA board, and a push rod body is installed at one end of the push rod spring. A power control line is connected to one end of the PCBA board. A drive motor is installed on one side of the top of the PCBA board. A motor cam is installed on one end surface of the drive shaft of the drive motor, and a pull rod is installed on the surface of the motor cam. The pull rod is sleeved on one end surface of the lever body. An anti-disengagement torsion spring is installed on one side of the lever body. A hook body is installed on the inner side of the lock body at the bottom of the lever body. A hook entry is opened on one side of the top of the hook body. A protrusion is provided on one side of the bottom of the lever body. The protrusion engages with the hook entry on one side of the hook body. A lever detection switch is installed on the inner wall of the lock body on one side of the lever. A push block body is installed on the inner wall of the lock body on one side of the lever detection switch. One side of the bottom of the push block body is located inside the hook of the hook body.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0011] 1. By combining the locking component with the push block body, the hook body can be pushed alone. The locking component cannot move downward because it is pressed down by the push block body below. As a result, when the hook body is pushed in, the protrusion of the locking component blocks it and it cannot be locked, thus achieving the anti-false lock function.
[0012] 2. By setting the four rounded corners of the lock body to plastic material, the molding process of the sheet metal lower shell is simplified by replacing sheet metal material with plastic material; by opening an emergency unlocking window on the surface of the lower shell on the upper left of the lever body, when the lock cannot work when powered on, the exposed end of the lever body can be pressed through the emergency window to achieve the purpose of manual unlocking.

Detailed Implementation
[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.
[0020] For an example, please refer to... Figure 1 As shown, this utility model provides a novel motor cabinet lock, including a lower shell 1, a lock body 2, an inner cover 10, and an upper shell 11. The lock body 2 is composed of a lever detection switch 3, a drive motor 4, a motor cam 5, a pull rod 6, a locking component 7, an anti-disengagement torsion spring 8, a lever body 9, a hook body 12, a hook torsion spring 13, a push block body 14, a push block spring 15, a push rod body 16, a push rod spring 17, and a PCBA board 18. A push rod spring 17 is installed inside the PCBA board 18, and a push rod body 16 is installed at one end of the push rod spring 17. A power control line is connected to one end of the PCBA board 18. A drive motor 4 is installed on one side of the top of the PCBA board 18. A motor cam 5 is installed on one end of the drive shaft of the drive motor 4. A pull rod 6 is installed on the surface of the motor cam 5. The pull rod 6 is sleeved on one end of the lever body 9. An anti-disengagement torsion spring 8 is installed on one side of the lever body 9. A hook body 12 is installed inside the lock body 2 at the bottom of the lever body 9. A hanging entrance is provided on one side of the top of the body 12. A protrusion is provided on one side of the bottom of the lever body 9. The protrusion engages with the hanging entrance on one side of the hook body 12. A lever detection switch 3 is installed on the inner wall of the lock body 2 on one side of the lever 6. A push block body 14 is installed on the inner wall of the lock body 2 on one side of the lever detection switch 3. One side of the bottom of the push block body 14 is located inside the hook of the hook body 12. A fixing rod is provided on one side of the hook of the hook body 12. A hook torsion spring 13 is sleeved on the surface of the fixing rod. A push block spring 15 is installed on the inner side of one end of the push block body 14. A locking part 7 is installed on the surface of the push block body 14 at the top of the push block spring 15. A protrusion is provided on the surface of the locking part 7. By matching the locking part 7 with the push block body 14, when the hook body 12 is pushed alone, the locking part 7 cannot move downward because it is pressed down by the push block body 14 below. As a result, when the hook body 12 is pushed in, it is blocked by the protrusion of the locking part 7 and cannot be locked, thus realizing the anti-false lock function.
[0021] like Figure 3 As shown, the lock body 2 and the inner cover 10 are fixedly installed by screws. The lock body 2 and the inner cover 10 are installed inside the lower shell 1 and the upper shell 11. The lower shell 1 and the upper shell 11 are fixed by bolts. By installing the lock body 2 and the inner cover 10 inside the lower shell 1 and the upper shell 11, the lower shell 1 and the upper shell 11 can play an effective protective role.
[0022] like Figure 3 As shown, the four R-corners of the lock body 2 are made of plastic. By setting the four R-corners of the lock body 2 to be made of plastic, the molding process of the sheet metal lower shell 1 is simplified by replacing the sheet metal material with plastic.
[0023] like Figure 3 As shown, an emergency unlocking window is provided on the surface of the lower left shell 1 of the lever body 9. By providing an emergency unlocking window on the surface of the lower left shell 1 of the lever body 9, when the lock cannot work when powered on, the exposed end of the lever body 9 can be pressed through the emergency window to achieve the purpose of manual unlocking.
[0024] like Figure 3 As shown, the inner wall of the lock body 2 is provided with a limiting block, and a slot is opened on one side surface of the hook body 12. One end of the hook torsion spring 13 is located inside the slot, and the other end of the hook torsion spring 13 is located inside the limiting block. Through the matching of the limiting block and the slot, the hook torsion spring 13 is supported at both ends.
[0025] Specific working principle:
[0026] Unlocking process: When the lock receives an unlocking signal from the power control line connected to one end of the PCBA board 18, the drive motor 4 is energized, causing its drive shaft to rotate. The rotation of the drive shaft drives the motor cam 5 to rotate as well. The pull rod 6 mounted on the surface of the motor cam 5 moves downward. The tail end of the lever body 9 moves downward under the force of the pull rod 6. The other end of the lever body 9 rotates clockwise upward around its center hole under the torque of the anti-disengagement torsion spring 8. When the protrusion on one side of the bottom end of the lever body 9 disengages from the hook inlet of the hook body 12, the pull rod 6 moves downward and touches the contact of the lever detection switch 3. At this time, the lever detection switch 3 provides an output signal. Under the torque of the anti-disengagement torsion spring 8, the hook body 12 rotates clockwise, popping out the lock hook, thereby achieving the purpose of unlocking.
[0027] Locking process: When the hook body 12 and the push block body 14 are pushed in from right to left at the same time, the hook body 12 overcomes the torque of the hook torsion spring 13 and rotates counterclockwise around its central hole. The push block body 14 compresses the push block spring 15 and moves to the left. The locking part 7 is pushed down by the hook body 12. Continuing to push the hook in will achieve the locking state.
