Lock body with double-quick function

Abstract

The invention provides a lock body with a double-quick function. Due to the fact that an avoiding opening is formed in the right side of the upper end of a lower guiding straight groove of a linkage plate of the lock body, and an elastic piece capable of making the linkage plate swing towards a lock cylinder is arranged on the linkage plate, when people turn a knob in a room to drive rotating of a dial wheel of the lock cylinder to push a lock tongue component to lock or open a door and the knob is continuously and slightly turned to enable the dial wheel to return, even if the dial wheel can make contact with the linkage plate, the dial wheel can act on the linkage plate, and the linkage plate slightly swings clockwise by an angle after acting force of the elastic piece is overcome, a lower guiding column slides into the avoiding opening, rotating returning of the dial wheel cannot be affected by the linkage plate, and thus the lock cylinder is not stuck by the linkage plate; and once pushing for the linkage plate is released by the dial wheel, the linkage plate can be straightened automatically, so that a heaven and earth pin linked by lifting of the linkage plate is not affected. The lock body with the double-fast function is more reasonable in structure and more reliable in using.

Description

technical field [0001] The invention belongs to a double fast function lock body. Background technique [0002] We know that whether it is a mechanical lock body or an electronic lock body, there are often bolt components, square tongue components, heaven and earth pins, linkage plates, etc., and people operate the handle or key to lock the bolt components inside and outside the door. 1. When the square tongue assembly is pushed out to lock the door or pulled back and retracted into the housing to open the door, the sky and earth pin is pushed out through the linkage plate to lock the door or pulled back into the housing to open the door. In addition, people can also turn the knob in the room, and the knob drives the dial on the lock cylinder to open and lock the door. Once the door is opened and locked, the knob must be manually turned to return the dial on the lock cylinder. Otherwise, when the door is locked or opened later, the dial may jam the deadbolt. In the current...

AI Technical Summary

Problems solved by technology

In the current lock body, when turning the dial to return to the original position, sometimes the linkage plate blocks the dial and affects the return to the original position.
