Novel heaven and earth lock structure

Abstract

The invention relates to a lock structure, in particular to a novel heaven and earth lock structure which is connected with primary and secondary lock bodies through a heavy and earth rod. The novel heavy and earth lock structure comprises a lock side frame as well as a primary lock box and a secondary lock box which are mounted in the lock side frame, wherein the primary lock box is positioned above the secondary lock box; an upper sheet-shaped connecting rod is arranged on the primary lock box; a lower sheet-shaped connecting rod is arranged on the secondary lock box; and the upper sheet-shaped connecting rod and the lower sheet-shaped connecting rod are connected through the heavy and earth rod. The novel heaven and earth lock structure is characterized in that a passing position of the heavy and earth rod on the end surfaces of the primary lock box and the secondary lock box is provided with a through hole, wherein an elastic limiting part for limiting the heavy and earth rod is arranged in the through hole. According to the novel heavy and earth lock structure, the elastic limiting part is arranged for limiting the periphery of the heavy and earth rod, so that normal operation, in a up-down direction, of the heavy and earth rod is guaranteed, a normal function of the lock is guaranteed, displacement, in a side direction, of the lock is restrained, the lock is prevented from releasing connection with the primary lock box and the secondary lock box, and stability, in transporting and mounting processes, of the lock is improved.

Description

technical field [0001] The invention relates to a lock structure, in particular to a novel sky-earth lock structure in which main and auxiliary lock bodies are connected by a sky-earth rod. Background technique [0002] In order to improve the anti-theft performance of the existing home door, while equipped with the main lock (open / close with the key), the configuration of the sky / ground lock is added to increase the number of lock points of the home door. According to the conventional design, the sky and earth lock and the main lock are arranged in The same side of the door leaf is connected with the main lock through the sky and earth lock rod. When the main lock is opened / closed, the sky and earth lock is driven to open / close by the action of the sky and earth rod. Generally, the one above the main lock is called the sky lock, and the one below the main lock is called the ground lock. [0003] Due to the limitation of the internal structure of the lock and the structure ...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitation of the internal structure of the lock and the structure diagram, shape, size and installation position of the door leaf, the existing main lock and auxiliary lock are connected freely, that is, through the elongated hole on the sky and earth rod and the piece on the main lock / auxiliary lock. The connecting rods are connected with each other, relying on gravity to maintain the connection relationship between the two, and there is no restriction on the degree of freedom. During the use of the door, especially during the transportation process, the placement position of the door will be changed from vertical / upright to sideways. Putting it horizontally or even upside down will cause the sky-earth rod to be separated from the main lock / sky-earth lock, resulting in the inability to open the sky-earth lock, which will cause great trouble to the user. If the lock column is damaged or even the entire door is destroyed, it will also bring users Economic losses
