the upper part of the vertical section of the L-shaped plate and the upper part of the lock shell are transversely provided with a through hole A, a through hole B and a through hole C in a penetrating manner;
the rod body part of the anti-theft nail sequentially penetrates through the through hole C, the through hole B and the through hole A in a sliding mode, a limiting plate is fixedly sleeved on the part of the accommodating cavity, and a spring is sleeved on the left part of the limiting plate;
the lower part of the lock shell is provided with a mounting hole, the lock body is cylindrical, the lock body extends into a position close to the anti-theft nail through the mounting hole, and a lock cylinder is arranged in the lock body;
the upper end of the lock shell is provided with a circular through hole communicated with the lock cylinder;
the blocking mechanism consists of a cross rod, a blocking rod fixed at the upper part of the left end of the cross rod and a connecting rod fixed at the lower part of the right end of the cross rod; the position of the cross rod is lower than that of the lower edge of the limiting plate; the stop lever is matched with the limiting plate in an abutting mode or rotates to the outer side of the limiting plate in the rotating process of the lock core.
The right end of the anti-theft nail is fixedly connected with a pressing plate.
The L-shaped plate and the lock shell are integrally formed.
In the invention, the rod body of the anti-theft nail transversely penetrates through the through holes A, B and C, so that the anti-theft nail can slide into the locking space to lock the commodity and can also slide out of the locking space to release the commodity. The spring can be arranged to eject the anti-theft nail to the right side when the limiting plate is not blocked, so that the anti-theft nail can be removed from the locking space. The blocking mechanism connected to the lock core can block the limiting plate in the rotation process of the lock core and release the limiting plate, so that the locking state and the unlocking state can be maintained conveniently. The mechanism can play a good anti-theft role and can meet the anti-theft requirements of some special commodities.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. the anti-theft lock comprises a lock shell, 2 parts of anti-theft nails, 3 parts of a lock body, 4 parts of a blocking mechanism, 5 parts of an accommodating cavity, 6 parts of an L-shaped plate, 7 parts of a locking space, 8 parts of a through hole A, 9 parts of a through hole B, 10 parts of a through hole C, 11 parts of a limiting plate, 12 parts of a spring, 13 parts of a lock core, 14 parts of a circular through hole, 15 parts of a cross rod, 16 parts of a connecting rod, 17 parts of a stop lever.
Detailed Description
The present invention will be further explained below.
As shown in fig. 1, a locking mechanism for theft prevention comprises a lock case 1, a theft prevention nail 2, a lock body 3 and a blocking mechanism 4; an accommodating cavity 5 is formed in the middle of the lock shell 1, an L-shaped plate 6 is fixedly connected to the left side of the lock shell 1, the horizontal section of the L-shaped plate 6 is fixedly connected with the lower end of the lock shell 1, and a locking space 7 is formed between the vertical section of the L-shaped plate and the left end face of the lock shell 1;
the upper part of the vertical section of the L-shaped plate 6 and the upper part of the lock shell 1 are transversely provided with a through hole A8, a through hole B9 and a through hole C10 in a penetrating manner;
