Abstract
The utility model discloses an improved horseshoe lock sawing-resistant structure, so that a horseshoe lock used on a bicycle has the better breakage-proof function. The improved horseshoe lock sawing-resistant structure is mainly characterized in that the two ends of a protective board of a shell track portion are provided with a first extending board and a second extending board respectively, the first extending board is provided with an annular plunger latch, the tail end of the first extending board compensates for an interval, and the second extending board extends into a reinforcement cover of a lock cylinder seat, so that no interval exists in the splicing positions of the reinforcing components of a horseshoe lock track portion, the disadvantage that the structure is prone to being sawn off is avoided, and when a burglar wants to destroy the splicing positions of the two ends of the protective board through a steel saw tool, the first extending board and the second extending board of the protective board can block and prevent a horseshoe lock from being sawn off. In this way, the improved horseshoe lock sawing-resistant structure can obtain better breakage-proof and antitheft effects.

This protected apron 18 still has with the stitching portion, two ends of the collar 14 and reinforcement cover 21 weakness that gap formation can be destroyed, make to want theft and can with hacksaw, cut housing 10,11 (note: housing often adopts the little allumen of intensity to make) herein, cause horseshoe lock can disconnect bending and can pirate of the open lock steal bicycle.
Utility model content
The utility model main purpose is to address the above problem, and provides a kind of improved horseshoe lock anti-saw structure, has better antitheft, practical effect.
The utility model provides a kind of improved horseshoe lock anti-saw structure, the holding part of housing upper end is provided with the coated lock core base of reinforcement cover, in the orbit portion of its lower end, group is established annular lock bolt, spring, this orbit portion both ends open is provided with the collar, this spring one end is connected in annular lock bolt, the other end connects, is fixed on the collar, and is provided with protected apron between this collar ora terminalis and reinforcement cover; This protected apron one end is provided with the first extension board.
This cover is equipped with the groove of corresponding the first extension plate.
This protected apron other end is provided with the second extension board.
This second extension board and reinforcement cover are overlapping.
The advantage the utlity model has is:
The utility model is provided with the first extension board and the second extension board in protected apron rear and front end, in cover, be equipped with the groove of corresponding the first extension board, make to form gapless between protected apron and lock bolt, and strengthen locating effect, and obtain making up the weakness of stitching portion, protected apron two ends, reach and strengthen preventing by the practical function of sawed-off horseshoe lock.
