Description

A new type of anti-theft lock

technical field

The invention relates to a novel anti-theft lock, which is especially suitable for motorcycles, electric bicycles and various door-control anti-theft locks.

Background technique

In the existing locks, since the lock cylinders are all on the exposed plane, the lock cylinders are susceptible to abnormal opening due to the action of various mechanical appliances, and the reliability and safety are poor.

Contents of the invention

In view of the above-mentioned technical deficiencies, the present invention provides a novel anti-theft lockset, which is composed of a round tube, a lock core, an iron chain, a connecting card, a lock bolt, and a key.

The present invention adopts the following scheme to realize: a new type of anti-theft lock, which is characterized in that: a lock core is installed in the middle of the section of the circular tube, the key insertion port of the lock core is facing the upper port of the circular tube, and the wall of the circular tube is There is a lock bolt insertion opening on the side, and one end of the lock bolt is connected with the connecting card at the lower end of the round pipe through an iron chain. The connecting card is welded on the round pipe, and the key can be inserted into the The long key to the lock cylinder.

The present invention is novel and unique in conception, and the realization scheme is concrete and practical. It can be widely used in various anti-theft places.

Description of drawings

Fig. 1, Fig. 2 are embodiment figure of the present invention.

Detailed ways

As shown in Figure 1, the purpose of the present invention is to provide a new type of anti-theft lock. In Figure 1, 1 represents a round tube, 2 represents a lock cylinder, 3 represents a lock bolt, 4 represents an iron chain, and 5 represents a connecting card. It is characterized in that: a lock core is installed in the middle of the section of the round tube, the key insertion port of the lock core is facing the upper port of the round tube, the wall side of the round tube has a lock bolt insertion opening, and one end of the lock bolt is The iron chain is connected with the connecting clip at the lower end of the round pipe, the connecting clip is welded on the round pipe, and the key is a long key that can be inserted into the lock cylinder through the upper port of the round pipe.

Fig. 2 is the embodiment figure of this novel anti-theft lock key, and the key is made of a long metal object, and its length is determined by the position of the lock core in the wall of the circular tube, generally 15-20 cm.

The specific working process of a new type of anti-theft lockset of the present invention is as follows: when the motorcycle or electric vehicle is to be anti-theft locked, first put the key into the round tube and touch the lock cylinder, rotate the key in a certain direction to move the lock bolt from It pops out from the opening on the side of the round pipe wall. One end of the lock bolt has been welded to one end of the iron chain, and the other end of the iron chain has also been welded to the connecting clip welded on the round pipe wall. . Like this, after the lock bolt that will be connected with iron chain passes through the wheel of electric vehicle or the wheel of motorcycle, the other end of the lock bolt that does not have welded iron chain is inserted in the opening of circular pipe wall side and buckles on the lock core. In this way, the effect of locking the wheels of electric vehicles or motorcycles is achieved. And because the lock cylinder is located in the round tube instead of being exposed on the plane at this time, it can prevent the lock cylinder from being easily affected by various mechanical appliances and cause abnormal opening, which improves the reliability and safety of the lockset and achieves a real anti-theft effect. When unlocking, you only need to insert the key into the lock core located in the wall of the round tube, and turn the lock core to eject the lock bolt from the opening on the side of the tube wall to achieve the unlocking effect.

The above are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
