Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft car locks, and more specifically to an anti-theft car lock. Background Art

[0002] With the development of society, transportation is becoming more and more convenient, among which electric bicycles are everywhere, so theft has also occurred. In order to effectively protect electric bicycles from theft, people will lock anti-theft locks on the wheels after the vehicles are parked. Traditional anti-theft locks are generally composed of a U-shaped frame and a lock head. Among them, the "anti-theft lock" disclosed in the application number "201620280667.6" has solved the various disadvantages of this structure of lock, such as applying force downward from the bar lock body, the end (lock tongue) of the U-shaped lock rod is easy to be disengaged from the lock hole, and this lock is violently opened, causing the vehicle to be stolen. However, in actual use, anti-theft locks with similar structures still have many defects, such as: the size of traditional anti-theft locks is fixed, and the size cannot be freely adjusted according to needs. If it is too small, it is easy to cause the vehicle to be unable to be locked. If it is too large, it is inconvenient to carry. At the same time, the keyhole of the traditional anti-theft lock lacks an effective protective structure, and it is easy to get dust and dirt, which makes it impossible for the key to be smoothly inserted into the keyhole, causing the anti-theft lock to be unusable. In view of this, we propose an anti-theft car lock. Utility Model Content

In order to limit the telescopic rod 2, it is ensured that the telescopic rod 2 can be stably telescoped inside the socket 101 and will not rotate. At least two groups of equidistant bayonet holes 201 are provided on the opposite sides of the two groups of telescopic rods 2. Through holes 301 are provided at both ends of the lock head 3, and a lock tongue 302 is provided on the side corresponding to the bayonet hole 201 inside the through hole 301. The two groups of telescopic rods 2 are inserted and installed with the lock head 3. When the lock head 3 is inserted into the two groups of telescopic rods 2, the lock tongue 302 of the through hole 301 of the lock head 3 will be stuck in the bayonet hole 201 of the telescopic rod 2, so as to lock it. A key hole 303 is provided at the center of the bottom of the lock head 3, and the key hole 303 is convenient for personnel to insert a key to unlock;

[0025] In this embodiment, when locking the vehicle to prevent theft, after the vehicle is parked, the U-shaped frame 1 is inserted into the vehicle wheel, and the telescopic rod 2 at the bottom of the U-shaped frame 1 can be freely adjusted and lowered as needed, and then the lock head 3 is inserted into the two sets of telescopic rods 2. At this time, the lock tongue 302 of the through hole 301 of the lock head 3 will be stuck in the bayonet 201 of the telescopic rod 2, thereby locking.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a protective structure 4 is fixedly installed at a position corresponding to the key hole 303 at the bottom of the lock 3, and the protective structure 4 is used to protect the key hole 303 from dust and water.
