Inner clamp type handle lock

Abstract

The invention discloses an inner clamp type handle lock. The inner clamp type handle lock comprises a first handle component, a second handle component, a lock box, a lock catch box, a key switching mechanism, a gear rack fixing device, an inner clamp type lock tongue movement mechanism and a manual rotary switching mechanism, wherein a lock cylinder is clamped with one end of a gear sleeve by a clutch lever sleeve, a clutch spring and an outer clutch lever; a rotary switch is clamped with the other end of the gear sleeve by an outer clutch lever; and the gear sleeve is meshed with a rack and drives a pair of inner clamp type lock tongues to perform front and back curvilinear motion, so that the lock catch box can be clamped or opened. With the adoption of the inner clamp type handle lock, a door with double leafs, a sliding door with double leafs or a single sliding door can be firmly and reliably locked; and the handle lock is simple and convenient to use, high in mechanical strength and excellent in prying-resistant performance and anti-theft performance, thereby adding a new element for the development of handle lock industry.

Description

technical field [0001] The invention relates to the technical field of handle locks, in particular to an internal clamp type handle lock. Background technique [0002] The existing handle locks generally use the form of heaven and earth locks to lock the door, but this type of handle lock can only lock one door. For double doors, two handle locks need to be equipped. Installation and use It is very troublesome and expensive. And because this kind of handle lock is locked in the form of a sky lock, the handle tube must be very long to connect the ground or the top frame of the door, and the handle tube must be made into a straight cylinder to facilitate the connection of the sky lock tongue or The deadbolt has caused this handle lock to have a single shape and a huge shape, which cannot adapt to people's aesthetic and humanized requirements of the times. And the straight bolt type handle lock will directly transmit the prying power to the inside of the lock body when being ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an internal clamp type handle lock, which solves the problems of double doors or double sliding doors or single sliding doors that cannot be locked firmly and reliably or require two locks to be locked and the single shape and straight lock. The tongue handle lock has poor anti-push and anti-prying performance. The internal clamp handle lock can firmly clamp and lock the two doors or the sliding door body and the lock box with the internal clamp lock tongue. Its installation And easy to use, high mechanical strength, anti-pry, anti-push, anti-shock, anti-theft performance is superior
