Referring to fig. 1 and 2, the embodiment of the limiting structure of the lock of the present invention is provided:

a limiting structure of a lockset comprises a bolt 1 and an extending hole arranged on a lock body shell. The bolt 1 is arranged in the lock body through the elastic resetting structure, and the bolt head 11 extends out of the extending hole under the action of the elastic resetting structure. The bolt head 11 comprises a curved slide-in surface 111 for sliding the bolt head 11 into a corresponding bolt hole in the door frame and a curved slide-out surface 112 for sliding the bolt head 11 out of the bolt hole.

As shown in fig. 1, the connection between the slide-in curved surface 111 and the slide-out curved surface 112 is a plug head 113, and the plug head 11 extends from the plug head 113 along the length direction and gradually outward to form a symmetrical structure with a narrow top and a wide bottom. The end adjacent to the plug head top 113 is a first spring contact surface 114 of the plug head 11, and a movable portion 12 of the plug is formed by extending from the first spring contact surface 114 to the end away from the plug head 11.

As shown in fig. 2, the elastic reset structure comprises a spring 2, a position-limiting component connected with the head part 11 of the bolt, and a mounting seat 4 movably connected with the movable part 12, and the position-limiting component 3 is positioned in the lock body shell. The mount 4 includes a mounting surface 42 fixedly connected to the lock body case and a second spring contact surface 41 contacting the spring 2, and the second spring contact surface 41 faces the plug pin 1 and is provided with a movable hole 411 for the movable portion 12 to pass through. The spring 2 is fitted to the movable portion 12, and one end of the spring 2 abuts against the first spring abutment surface 114 and the other end abuts against the second spring abutment surface 41. The bolt head 11 moves towards the direction of the mounting seat 4 under the action of external force and compresses the spring 2; when the bolt head 11 is free from external force, the bolt head 11 extends out of the lock body shell, and the limiting part is propped against the inner side surface of the lock body shell, so that the bolt 1 is not separated from the lock body shell.

In the embodiment of the present invention, the movable portion 12 is rod-shaped and has one end connected to the plug head 11. The plug 1 is a flat metal plate in the shape of an arrow. The mounting surface 42 of the mount 4 is perpendicular to the second spring abutment surface 41.

Specifically, the limiting component is a U-shaped metal limiting needle 3, the plug pin head 11 is provided with two limiting holes 115, and two ends of the limiting needle 3 respectively penetrate out of the two limiting holes 115. When the head part 11 of the bolt is not subjected to external force, the U-shaped surface of the limiting pin 3 is abutted against the inner side surface of the lock body shell; when the bolt head 11 is acted by external force, the limiting pin 3 moves towards the direction of the mounting seat 4 together with the bolt head 11.

Two applications of embodiments of the present invention are presented below:

will the utility model discloses limit structure and the tool to lock that is equipped with spring bolt structure combine, and the pore wall that slides in curved surface 111 and door frame bolt hole when closing the door collides, and bolt head 11 removes towards the lock body under the effect of external force, and bolt head 11 stretches out the lock body and blocks in the bolt hole under the effect of elasticity reset structure after that. Because the elastic coefficient of the elastic reset structure of the limit structure is greater than that of the spring bolt structure, the problem of door rebounding caused by collision between the spring bolt and the wall of the spring bolt hole due to excessive force can be effectively avoided. When the door is opened, the sliding curved surface 112 collides with the wall of the bolt hole of the doorframe, and the bolt head 11 moves towards the lock body under the action of external force and is separated from the bolt hole.

When the demand of tool to lock privacy protection, the lock body shell is equipped with the utility model discloses the limit structure need not to set up the lock core, can realize opening the door and close the effect of door for tool to lock simple structure.
