Rotating latch head and latch beating mechanism with the same

Abstract

The invention discloses a revolving bolt head and a bolt beat mechanism with the revolving bolt head. The invention relates to a revolving bolt head which comprises a main bolt head and is characterized by also comprising an upper bolt head, a lower bolt head and a rotary shaft; wherein, the main bolt head is internally provided with a radial hole and a axial hole; the upper bolt head and the lower bolt head are inserted in the radial hole oppositely and can slide up and down relatively to the radial hole; the rotary shaft is inserted in the radial hole and can rotate relatively to the radial hole; the inner end of the upper bolt head is provided with an upper connection hole and the inner end of the lower bolt is provided with a lower connection hole; the internal end surface of the rotary shaft is provided with two connection columns which are inserted in the upper connection hole and the lower connection hole respectively so as to allow the rotary shaft to rotate and bring the upper and the lower bolt head to slide up and down relatively to the radial hole. The rotary shaft brings the upper and the lower bolt head to slide up and down relatively to the radial hole so as to go out of or withdrawn in the main bolt head by the matching of the connection columns and the connection holes of the upper and lower bolt heads at the front end of the rotary shaft; and therefore, the upper bolt and the lower bolt head can hook the interior wall of the bolt hole respectively, thereby enhancing the pick-proof effect of the bolt head.

Description

technical field [0001] The invention relates to a revolving bolt head and a latch mechanism with the revolving bolt head. The revolving bolt head and the bolt mechanism can be applied to various safes, anti-theft cabinets, storage boxes, filing cabinets, and weapons. Anti-theft doors for cabinets, safes and households. Background technique [0002] The structure of the existing safe cabinet door mainly includes a door frame, a door body pivotally connected to the door frame, and a bolt structure arranged between the door body and the door frame. The interlocking door bolt is provided with a bolt hole corresponding to the side door bolt on the door frame. The door bolt is cylindrical, and the bolt hole is a cylindrical hole matched with the door bolt. There are some defects in this kind of safe cabinet door. If the criminals pry the door frame instead of the lock, since there is no obstructing structure between the bolt and the bolt hole, as long as the criminals only need ...

AI Technical Summary

Problems solved by technology

[0005] 1. Although the existing revolving door latch has a special-shaped head combined with the sleeve of the corresponding part of the box to form a buckle, it is added on the basis of the ordinary door latch, and the "L"-shaped chute hole and the connector are required. Cooperating with each other, the rotary bolt can rotate relative to each other, and cannot be integrated with the ordinary door latch, the production cost is relatively high, and the transmission is not easy

[0006] 2. During the working process of the aforementioned bolt mechanism, with the movement of the bolt, the bolt rotates passively, that is to say, as long as the bolt head can move normally, the safety bolt can be opened, and the bolt head is generally driven by a slide plate, and the slide plate It is locked by a lock structure to determine whether the slide plate moves, so as long as the lock structure is destroyed, the safety latch can be opened, so the safety of the aforementioned safety latch is not enough
