Detailed ways

In order to have a further understanding and understanding of the structure, technical features and effects of the present utility model, hereby give some embodiments, and in conjunction with the accompanying drawings, describe in detail as follows:

Referring to Fig. 1, the first embodiment of the present utility model is a car anti-theft device, which mainly includes: a seat body 1, an electromagnet 2, a limiting block 3 and a clamping block 4; wherein:

The seat body 1 is provided with a positioning plate 11 at one end, and a through hole 111 is provided on the positioning plate 11. An accommodating hole 112 is provided inside the through hole 111, and an accommodating hole 113 is respectively recessed on the upper and lower sides of the through hole 111. The content of the cavity 113 is provided with an elastic element 114, and the elastic element 114 pushes against the embedded bead 115 outwards. The other end of the base body 1 is provided with a positioning block 12 corresponding to the positioning plate 11, and the positioning block 12 corresponds to the through hole of the positioning plate 11. 111 is provided with a through hole 121 , and the inner ends corresponding to the two sides of the positioning block 12 of the seat body 1 are respectively provided with fixing blocks 13 , while the inner ends of the positioning block 12 are provided with switches 14 .

The electromagnets 2 are respectively fixed on both sides of the base body 1 , each electromagnet 2 protrudes from a linkage rod 21 , and the linkage rod 21 is fixedly connected to the lug 31 of the limiting block 3 by means of a fixing member 211 .

The limiting block 3 is just arranged between the positioning plate 11 and the positioning block 12 of the seat body 1, and is fixed and limited by two fixing blocks 13. The corresponding positioning plate 11 of the positioning plate 11 is concavely provided with an embedding hole at the position of the limiting block 3 32, the embedding hole 32 is connected with the embedding hole 34 on the other side by the guide groove 33, for the bead 115 to slide and position in the embedding holes 32, 34 and the guide groove 33, and the limit block 3 corresponds to the seat body 1 A perforation 35 is formed at the receiving hole 112 of the positioning plate 11 , and a through groove 36 is connected to one side of the perforation 35 .

The clamping block 4 is just set and fixed on the steel cable 41 of the switch engine cover, and the clamping block 4 can be accommodated in the accommodation hole 112 of the positioning plate 11 through the perforation 35 of the limiting block 3. The clamping block 4 cannot pass through the slot 36 so as to keep in contact with the switch 14 .

As shown in Figure 2-4, when in use, when the user activates the lock, the electromagnet 2 pushes the limit block 3 to move to one side through the linkage rod 21, so that the slot 36 of the limit block 3 just moves to Corresponding to the steel cable 41 set by the clamping block 4, the embedded bead 115 pushed by the elastic element 114 in the hole 113 of the positioning plate 11 of the seat body 1 is just embedded in the embedded hole 32 of the limiting block 3, and at the same time, the external connection is opened. At this time, if a robber pulls the steel cable 41 forcibly and wants to open the engine cover (not shown in the figure), the steel cable 41 is under the restriction of the stop block 3, then Unable to drive the clamping block 4 to continue to move forward, so the engine cover cannot be opened, and because the clamping block 4 is in a conflicting state with the switch 14 at this moment, once the steel cable 41 is pulled, the clamping block 4 is shifted, and it is no longer pushed up. When the switch 14 is reached, another spare alarm can be triggered to give an alarm, so that unscrupulous people cannot directly forcibly steal the vehicle away, so it has a reliable and effective anti-theft function.

As shown in Figure 5-7, when the locked state is released, the electromagnet 2 will drive the limit block 3 to slide to the other side, so that the limit block 3 will correspond to the steel plate of the clamping block 4 with the perforation 35 cable 41, and the embedded beads 115 in the seat body 1 positioning plate 11 cavity 113 are also moved to the other embedded hole 34 along the guide groove 33 for positioning. The block 4 passes through the perforation 35 of the limiting block 3 and is accommodated in the accommodating hole 112 of the positioning plate 11 of the seat body 1, so that the engine cover can be opened smoothly.

Referring to Fig. 8, the structure of the second embodiment of the utility model is basically the same as that of the first embodiment, the difference is that an arc-shaped guide block 15 is provided on the seat body 1, and an arc-shaped guide block 15 is provided with a channel hole 151, and an arc-shaped stop block 3' is pivotally arranged on the inner edge of the arc-shaped guide block 15. When the lock is locked or unlocked, the electromagnet 2 can be used to drive the stop block 3' on the arc-shaped guide block 15. The inner edge moves in an arc, and the clamping block 4 can also be used to lock the outside of the slot 36' of the limit block 3' for anti-theft, or unlock it through the perforation 35' of the limit block 3', and it can be opened smoothly hood.

In addition, the utility model can be fixed with an oil pressure device or an air pressure device (not shown in the figure) that is pivotally connected with the lug 31 of the limit block 3 on the seat body 1, and the oil pressure device or air pressure device can also be used to drive the limit position. Block 3 slides to achieve the purpose of locking or unlocking.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model. Those who are familiar with this art can use the principles and technical characteristics of the present utility model to make various changes and decorations. , should be covered within the scope of protection of the claims.
