Abstract

The utility model relates to a high-security bicycle horseshoe lock, which comprises a lock shell, a lock ring, a tension spring, a lock gate and a spanner. The lock shell is provided with a C-shaped tubular lock ring cavity and a lock head cavity, the lock ring and the tension spring are arranged in the lock ring cavity in a sliding way, the lock shell is formed by combination of a bottom plate and a cover plate, the outer edge of the bottom plate is folded up to wrap the outer edge of the cover plate, and the inner wall of the lock ring cavity is lined with a lock ring cavity liner. Since the outer edge of the bottom plate is folded up to wrap the outer edge of the cover plate, the strength of combination is enhanced, and the difficulty in burglary is increased. In addition, since the inner wall of the lock head cavity is lined with a high-strength lock head cavity liner subject to heat treatment, the defect that the corresponding lock ring liner part in the lock ring cavity can be easily sawed off after locking can be overcome, and the security of a whole lock body can be improved.

Description

High anti-theft bicycle horseshoe lock
Technical field
The utility model relates to a kind of bicycle lock, especially a kind of high anti-theft bicycle horseshoe lock with pick-proof, anti-saw function.
Background technology
Because the bicycle horseshoe lock is very easy to use, therefore still have many bicycles to select for use horseshoe lock in daily life as lock.The bicycle horseshoe lock comprises lock shell, lock ring, extension spring, stop and spanner; Said lock shell is provided with C shape tubulose lock ring cavity volume and tapered end cavity volume, and lock ring and extension spring are slidably disposed in the lock ring cavity volume, and an end of lock ring is connected with an end of extension spring; The other end of extension spring is fixed; Spanner is connected with stapled, is provided with tapered end and stop in the tapered end cavity volume, is provided with transmission mechanism between tapered end and the stop.Because the lock shell of existing horseshoe lock is directly fitted by two of front and back and forms, and pastes part mutually and leaves obvious gaps, is prized easily; In addition, also have some positions relatively weaker, do not have the position of lock ring phase contrast in the back lock lock ring cavity volume of particularly locking; By sawed-off, cause bicycle stolen easily.
Summary of the invention
In order to overcome the deficiency of prior art, utility model provides a kind of high anti-theft bicycle horseshoe lock with pick-proof, anti-saw function.
To achieve these goals, the technical scheme that utility model adopts is: a kind of high anti-theft bicycle horseshoe lock comprises lock shell, lock ring, extension spring, stop and spanner; Said lock shell is provided with C shape tubulose lock ring cavity volume and tapered end cavity volume, and lock ring and extension spring are slidably disposed in the lock ring cavity volume, and an end of lock ring is connected with an end of extension spring; The other end of extension spring is fixed, and spanner is connected with stapled, is provided with tapered end and stop in the tapered end cavity volume; Be provided with transmission mechanism between tapered end and the stop; It is characterized in that: the lock shell is formed by base plate and two merging of cover plate, and folding encases the cover plate outer rim on the said plate outer side edge, and said tapered end cavity volume inwall is lined with tapered end cavity volume liner plate.
Adopt such scheme,, strengthened the intensity that mutually combines, increase the difficulty of robber's picking lock because folding encases the cover plate outer rim on the plate outer side edge; In addition, be lined with through heat treated high strength tapered end cavity volume liner plate at tapered end cavity volume inwall, having remedied the back interior correspondence of lock lock ring cavity volume of locking does not have lock ring phase contrast position easily by sawed-off defective, has improved the whole theftproof performance of lock body.
As the further setting to the utility model, the both sides, front and back of tapered end all are lined with tapered end cavity volume liner plate in the said tapered end cavity volume, can prevent further that like this robber from cutting the destruction stop with the tapered end cavity volume, thereby illegally will lock unlatching.
As the further setting to the utility model, said tapered end key insertion end is provided with anti-drilling sheet, tapered end is destroyed with electric drill further to prevent the robber, thereby illegally will lock unlatching.
Below in conjunction with accompanying drawing and specific embodiment utility model is further described.
