Abstract

The utility model relates to an improved structure of antitheft lock box on bicycle storage frame, relating to the improved structure of a lock box on bicycle storage frame for preventing a bicycle from being stolen. The improved structure of antitheft lock box on bicycle storage frame is mainly characterized in that one end of a lock rod is connected with a cross rod, the cross rod is also connected with a lever, and the other end of the lever is contracted with an electromagnet; a fixed block is arranged at the mutual connecting position among the lock rod, the cross rod and the lever, and a spring is arranged between the cross rod and the fixed block. The improved structure of antitheft lock box on bicycle storage frame uses lever principle, the electromagnet is not directly connected with the lock rod, but the electromagnet is connected with the lock rod via the lever and the cross rod; opening power can be increased even the electromagnet and the lock rod can not be clamped.

Description

The improvement structure of lock box on the antitheft parking frame

Technical field:

The utility model relates to the improvement structure that can prevent lock box on the stolen bicycle storing frame of bicycle.

Background technology:

I have the technology of just applying for a patent of a remote-control anti-theft parking device, and it mainly is made of parking frame and the lock box that is fixed on the vehicle frame, and parking frame is provided with triangular support bracket, is provided with strut bar between the two triangle bracing frames, is fixed with several lock boxes on the strut bar; Lock box is " U " shape, in be provided with the latch hook of two symmetries, circular after the two latch hook closures, latch hook is fixed on the locking bar by hinge plate and straight pin activity respectively again, locking bar is connected with lock core; Also be provided with remote-control receiving circuit unit, switch and warning circuit unit, source switch, junction block in the lock box.The shortcoming that it mainly exists is that lock box is not often opened, and reason is that electromagnet directly is stuck in the locking bar groove, is easy to block cause activity dumb.

Summary of the invention:

The purpose of this utility model is to overcome above deficiency and a kind of simple in structure, the improvement structure that can open the lock box of lock box easily is provided.

The utility model is achieved by the following technical solution: the improvement structure of lock box on this antitheft parking frame, comprise that the latch hook that is provided with two symmetries in lock box, the lock box, latch hook are fixed on the locking bar, also are provided with electromagnet in the lock box by the fixed block activity by hinge plate and straight pin respectively again, its major technique feature is that described locking bar one end connects locking bar, cross bar is connected with lever again, and the lever other end and electromagnet are collided; There is a fixed block at described locking bar, locking bar, the lever place of interconnecting, are provided with spring between cross bar and the fixed block; Latch hook and locking bar bonded assembly fixed block are " worker " font, and the centre is provided with the hole.

The utility model utilization lever principle, electromagnet directly is not connected with locking bar, but pass through lever, cross bar is connected with locking bar, even can not block between electromagnet and the locking bar, can increase again and turn on the power.

Description of drawings:

Fig. 1 is the scheme drawing of the improvement structure of lock box on the antitheft parking frame;

The fixed-block-architecture (FBA) scheme drawing that Fig. 2 is connected for the latch hook locking bar.

The specific embodiment:

As shown in Figure 1, lock box is " U " shape, in be provided with the latch hook 1 of two symmetries, circular after the two latch hook closures, locking bar 2 one ends connect cross bar 3, and cross bar is connected with lever 4 again, and the lever other end and electromagnet 5 are collided, there is a fixed block 8 at locking bar, locking bar, the lever place of interconnecting, are provided with spring 6 between cross bar and the fixed block 8.

As Fig. 2, shown in Figure 3, latch hook and locking bar bonded assembly fixed block 7 are " worker " font, and the centre is provided with the hole, and the hole is used for fixing locking bar and uses.

Claims

1, the improvement structure of lock box on a kind of antitheft parking frame, comprise that the latch hook that is provided with two symmetries in lock box, the lock box, latch hook are fixed on the locking bar, also are provided with electromagnet in the lock box by the fixed block activity by hinge plate and straight pin respectively again, it is characterized in that described locking bar one end connects cross bar, cross bar is connected with lever again, and the lever other end and electromagnet are collided.

2, the improvement structure of lock box on a kind of antitheft parking frame as claimed in claim 1 is characterized in that there is a fixed block at described locking bar, locking bar, the lever place of interconnecting, are provided with spring between cross bar and the fixed block.

3, the improvement structure of lock box on a kind of antitheft parking frame as claimed in claim 1 is characterized in that described latch hook and locking bar bonded assembly fixed block are " worker " font, and the centre is provided with the hole.
