Description

Horseshoe lock anti-saw structure improvement

This creation is a modification of the horseshoe lock anti-saw structure, especially one that enhances the strength of the joints at both ends of the guard plate of the track portion.

Since bicycle horseshoe locks are very convenient to use, many bicycles in their daily life use horseshoe locks as anti-theft locks. For example, as shown in the first and second figures, the housing portion 12 of the upper end of the two pairs of housings 10 and 11 is assembled with the lock core seat 20, and the receiving portion 12 is further provided with reinforcement. The cover 21 covers the lock core seat 20, so that when the housings 10, 11 are subjected to foreign matter damage, the reinforcing cover 21 is still protected from the lock core seat 20, so as to prevent the lock core seat 20 from being damaged and stolen. In addition, an annular latch 16 and a spring 17 are disposed in the rail portion 13 at the lower end of the housing 10, 11. The rail portion 13 is open at both ends with collars 14, 15 which are connected at one end to the annular latch 16 and One end is connected and fixed to the collar 14, so that the spring 17 is elastically stretched, and the annular latch 16 is slid in the rail portion 13, and a shield 18 is disposed between the housing 10, 11 and the spring 17, and one end thereof is abutted. At the end edge of the collar 14, the other end abuts against the edge of the reinforcing cover 21, and after the horseshoe lock is locked, there is no defect that the phase of the annular latch 16 in the rail portion 13 is easily sawn off. Therefore, the current rail portion 13 When subjected to foreign object damage or sawing, there is still a protective plate 18 to protect the horseshoe lock from being sawn and the bicycle is stolen; however, the above structure has the following disadvantages: the protective plate 18 and the collar 14 and The joints at both ends of the reinforcing cover 21 still have a gap to form a weak point that can be destroyed, so that the person who wants to steal will saw the shells 10 and 11 with a hacksaw (Note: the shell is often made of zinc aluminum alloy with little strength) Made), causing the horseshoe lock to break and bend and steal the lock to steal the bicycle.

The main purpose of this creation is to solve the above problems, and to provide a horseshoe lock anti-saw structure improvement, with better anti-theft and practical effects, the main technology and purpose are:

Attached to the front and rear ends of the fender are provided with a first extension plate and a second extension plate, in the collar The groove corresponding to the first extension plate is provided to form a gap between the reinforcing plate and the latch, and the positioning effect is enhanced, and the weak point of the joint at both ends of the protection plate is compensated for, thereby enhancing the practical effect of preventing the sawhorse from being cut off. .

In order for your review board to have a better understanding of the creation, a preferred embodiment will be described in conjunction with the drawings, as detailed below:

Referring to Figures 3 and 4, the accommodating portion 32 of the upper end of the housing 30, 31 is provided with a reinforcing cover 41 covering the lock core seat 40, and the lower end rail portion 33 is provided with an annular latch 36 and a spring 37. The ends of the rail portion 33 are respectively provided with collars 34 and 35. The spring 37 is connected at one end to the annular latch 36, and the other end is coupled and fixed to the collar 34, so that the spring 37 is elastically stretched, and the ring latch 36 can be a sliding plate is disposed in the rail portion 33, and a shielding plate 38 is disposed between the housing 30, 31 and the spring 37. One end thereof abuts against the end edge of the collar 34, and the other end abuts against the edge of the reinforcing cover 41. The end is provided with a first extension plate 381 and a second extension plate 382. The collar 34 is provided with a corresponding groove 341 corresponding to the first extension plate 381, and the reinforcement cover 41 is provided with a corresponding second extension plate. 382 and overlap with the reinforcing cover 41; by the above configuration, the first and second extension plates 381, 382 are blocked to prevent the sawhorse from locking off the horseshoe lock.

The composition of this creation, the details are as follows: Please refer to Figures 3 and 4, the housing 30, 31, spring 37 of the horseshoe lock is made of zinc-aluminum alloy with low strength and general metal material, and its ring latch 36 The collar 34, the protective plate 38 and the reinforcing cover 41 are heat-treated high-strength steel materials, so that they can resist drilling and anti-saw and prevent the bicycle from being easily damaged; when the horseshoe lock is in a locked state (such as 4, the annular latch 36 is closed through the rail portion 33 to close the two end openings, the end of the annular latch 36 is inserted into the collar 34, and one end of the shield 38 is abutted against the end edge of the collar 34. The other end is abutted against the reinforcing cover 41, and the first extending plate 381 is embedded in the groove 341 of the collar 34 to compensate for the gap between the protective plate 38 and the end edge of the collar 34, and the second extending plate 382 is overlapped with the reinforcing cover 41. Moreover, the thickness of the overlap does not affect the sliding of the annular latch 36, so that when the protective plate 38 is slightly loosened, no gap is generated, and the positioning function is better, so that the rail portion 33 has the annular latch 36, the protective plate 38, and the sleeve. The ring 34, the first and second extension plates 381 and 382, and the reinforcing cover 41 are connected to form a ring-shaped reinforcing structure, and the position of the track portion 33 is not weakened by any sawing, thereby preventing the thief from cutting the horseshoe lock. So forced to open the stolen bicycle.

As can be seen from the above, this creation has the following functions and advantages:

(1) The track portion 33 of the horseshoe lock forms a "comprehensive annular reinforcement", and any position has a protective member made of steel to achieve the anti-theft and anti-saw anti-theft effect of the horseshoe lock.

(2) The first and second extension plates 381 and 382 are arranged to overlap the plurality of reinforcing members, thereby increasing the difficulty of being sawed and achieving a better anti-theft effect.

In summary, the structure of this creation does have excellent practicality and enhanced efficiency. It is in line with the provisions of the Patent Law, and it is submitted in accordance with the law.
