AI Technical Summary
In the case of a power outage or motor jam in existing electronic locks, the locking push rod of the lock body cannot be reset, resulting in problems such as being unable to unlock and abnormal switching.
An anti-stuck mechanical lock body structure is designed, including a locking push rod assembly, a rotating shaft, a main gear, a lower paddle and a push rod reset spring. The locking push rod assembly is pushed by rotating the key paddle, and the inclined surface of the lower paddle is separated from the main gear to achieve the anti-stuck effect.
It effectively prevents the lock body locking push rod from not resetting due to the lock motor being stuck or abnormal power failure, ensuring the normal opening and unlocking functions of the lock.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical locks, and in particular relates to an anti-jamming mechanical lock body structure. Background Art
[0002] An electronic lock is an electronic product that uses a circuit or chip-based access control system to control the closing of a mechanical switch to complete unlocking and locking tasks. With the development of society, electronic locks have gradually become the mainstream locks in the market due to their ease of use. The lock body is one of the important components of an electronic lock and plays an important role in anti-theft. In the event of a power outage or motor jam, the locking push rod of the existing lock body cannot be reset, resulting in problems such as being unable to unlock or switch abnormalities. To this end, we propose an anti-jamming mechanical lock body structure to solve the above problems. Utility Model Content
[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides an anti-stuck mechanical lock body structure, which effectively solves the problem that the lock body of the existing electronic lock is easily unable to reset the locking push rod in the event of power outage or motor jamming, resulting in the inability to unlock and abnormal switching.
[0004] The technical solution adopted by the present invention is as follows: The present invention proposes an anti-stuck mechanical lock body structure, including a locking push rod assembly and a rotating shaft, the locking push rod assembly is fixed to the external cover plate by rivets, the rotating shaft is arranged above the locking push rod assembly, the locking push rod assembly includes a locking push rod 1 and a push rod guide column, the push rod guide column is vertically arranged on the side of the locking push rod 1, a main gear and a lower paddle are sequentially provided on the rotating shaft, and the side edge of the main gear is sleeved on the push rod guide column, a push rod reset spring is sleeved on the push rod guide column, and the other end of the push rod reset spring is arranged on the main gear.
[0005] Furthermore, one side of the lower paddle is engaged with a sub-gear, and one movable end of the sub-gear is slidably connected to a lock tongue, and a key paddle is provided on the outer side of one end of the locking push rod, and the key paddle is in contact with the side end surface of the locking push rod.
[0006] Furthermore, a slope is provided at the lower end of the lower paddle, and one side of the locking push rod is L-shaped.
[0007] The beneficial effects achieved by the utility model using the above structure are as follows:
[0008] The locking push rod assembly is pushed upward by the thrust force to push the main lock tongue into place and then separates against the lower paddle slope to prevent jamming. At this time, the handle opening and key transmission do not interfere with each other, which can prevent the lock motor from getting stuck or abnormal power failure, resulting in the lock body locking push rod not being reset and causing the abnormal unlocking.
