Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in fig. 1, 2, 3 and 4, the anti-theft device for the sliding door comprises a lock body 1, a wheel body 4, a T-shaped strip, a cross lath 5 and an inclined lath 6; the lock body 1 comprises a key hole 11, a rotary wheel 15 and a convex head 16, wherein the rotary wheel 15 and the convex head 16 are integrally formed; the wheel body 4 comprises a wheel shaft 8, a roller 7, a first convex head 9 and a second convex head 10, the roller 7 is connected with the wheel shaft 8 in a rolling way, and the first convex head 9, the second convex head 10 and the roller 7 are integrally formed; the T-shaped strip comprises a transverse pin 3 and a vertical plate strip 2, the transverse pin 3 and the vertical plate strip 2 are integrally formed, a groove 14 is formed at one end, close to the end part, of the vertical plate strip 2, close to the protruding head, and the transverse pin 3 is provided with a chute 13; one end of the transverse lath 5 close to the end is provided with a groove 14, and the inclined lath 6 is integrally formed with the other end of the transverse lath 5.
