Description

Anti-demolition motorcycle, electric vehicle, bicycle lock

technical field

The utility model relates to the technology in the field of anti-theft locks applied to motorcycles, electric vehicles, bicycles, etc., in particular to an anti-disassembly lock for motorcycles, electric vehicles, and bicycles.

Background technique

In order to prevent theft of motorcycles, electric vehicles, bicycles, etc., relevant personnel have designed a variety of lock structures, such as wire chain locks and U-shaped locks. The rotation of the wheel is limited to achieve the purpose of locking the car. In fact, the steel wire chain lock or U unlocking etc. are easy to be cut off due to the long part extending out from the hub, thereby causing the motorcycle, electric car or bicycle to be stolen. Simultaneously, this kind of lock needs lockset to be taken off from the car when unblanking, and needs to put on again when locking, and makes user bring a lot of inconveniences.

In view of this situation, a kind of lock set that is directly mounted on the car appeared later. This lock set no longer needs to be taken off from the car when it is unlocked, and it does not need to be reinstalled when it is locked, which greatly facilitates people's use. Because the lock bolt is stuck between the hubs when it is locked, unlike the wire chain lock or U unlocking that has a longer part protruding from the hub, this kind of lock can prevent the lock from being cut off. However, in use, this kind of lock also has disadvantages, for example, the position where the lock is installed is exposed at the top, and the thief can still disassemble the lock from the installation through the firm screw to achieve the purpose of stealing.

Therefore, it is necessary to develop a new technical solution to solve the above problems.

Utility model content

The utility model aims at the deficiency of the prior art, and provides an anti-disassembly lock for motorcycles, electric vehicles and bicycles which can effectively prevent criminals from stealing by disassembling the lock.

For reaching above-mentioned purpose, the technical scheme that the utility model adopts is as follows:

An anti-disassembly lock for motorcycles, electric vehicles and bicycles, comprising a lock body and a lock cylinder, the lock body is provided with fastening positions for fixed connection with motorcycles, electric vehicles and bicycles, the lock body is A cover plate is provided at the fastening position, and a limit block is extended downward from the cover plate, and a limit hole is provided on the limit block, and a retractable protrusion matching the limit hole is provided in the aforementioned lock core. Post: In the locked state, the protruding post protrudes and is inserted into the limit hole; in the unlocked state, the protruding post shrinks away from the limit hole.

As a preferred solution, the lock body is fixed with the front insertion rod of the motorcycle, electric vehicle or bicycle by the fastener at the fastening position, and the cover plate is provided with a socket for accommodating the head of the fastener. Give way to grooves.

As a preferred solution, the lock body includes a sleeve portion and a main body, the sleeve portion has a gap, the lock core is arranged in the sleeve portion and can move up and down in the sleeve portion, the cover plate A fitting portion corresponding to the notch of the sleeve portion is provided, and the aforementioned limiting block is formed by extending downward from the fitting portion.

As a preferred solution, the main body of the lock body is provided with a limit plate, and the lock body is provided with a recess between the lock core and the limit plate. When the cover plate is combined with the lock body, the matching The part is sealed in the notch of the sleeve part, and the bottom of the limiting block is inserted into the recess.

As a preferred solution, an accommodating groove is provided at one end of the protruding post located inside the lock cylinder, and a return spring is arranged in the accommodating groove.

As a preferred solution, the protruding column is located at one end of the accommodating groove and extends a hook in a transverse direction. When locking, the internal components of the lock cylinder are snapped into the hook and drive the protruding column to shrink. The core moves in the sleeve part, and when it moves to the locking position, the aforementioned return spring pushes the protruding column out and inserts it into the aforementioned limiting hole, and the end of the protruding column approaches or touches the limiting plate; when the lock is unlocked, the lock cylinder The internal component is clipped to the hook and drives the protruding post to shrink, and the protruding post moves out of the locking position along with the lock cylinder.

As a preferred solution, the cover plate is fixed to the upper end of the lock body by fastening screws.

Compared with the prior art, the utility model has obvious beneficial effects by adopting the above technical scheme. By setting a cover plate at the fastening position where the lock body is fixedly connected with motorcycles, electric vehicles, and bicycles, the cover plate faces A limit block is extended from the bottom, the limit block is provided with a limit hole, and the aforementioned lock core is provided with a retractable boss that matches the limit hole, when the lock is in the locked state, the boss protrudes, It is inserted into the limit hole, thereby achieving the purpose of locking the cover plate from the inside when it is locked, so that the cover plate is not easy to be disassembled when it is locked. Since the cover plate covers the lock body fastened to the motorcycle, In addition to the fasteners on the electric car or bicycle, the phenomenon that the entire car lock is disassembled in the traditional technology and causes the motorcycle, electric car or bicycle to be stolen is prevented.

Secondly, the main body of the lock body is also provided with a limiting plate, and the limiting block of the cover plate is located between the lock cylinder and the limiting plate. When locking, the boss is inserted into the limiting hole, and the end of the boss is Close to or against the limit plate, so that the limit block has no space to move out of the boss, thereby ensuring that the cover plate will not be forcibly pried open, and further improving the safety of the use of the lock.
