Plug-in connecting square bar structure

Abstract

The invention discloses a plug-in connecting square bar structure which comprises an outer square bar body and an inner square bar body, wherein a plug-in hole is used for being connected with the outer square bar body is formed in one end part of the inner square bar body; an elastic hook is arranged on one side surface of the end part of the inner square bar body; one end part of the elastic hook extends forward into the plug-in hole; a locking pin is arranged at the end part of the elastic hook; a plug-in column matched with the plug-in hole is arranged on the outer square bar body; and a ring-shaped groove is formed in the plug-in column. According to the plug-in connecting square bar structure, the plug-in column is inserted into the plug-in hole, and the locking pin is locked into the ring-shaped groove under the action of elastic force, thereby finishing the mounting operation; at the moment, the outer square bar body is hooked by the elastic hook and cannot be pulled out, but both the inner square bar body and the outer square bar body can freely rotate; during the unlocking and replacement of the outer square bar body, all that is needed for pulling out the outer square bar body is to separate the locking pin of the elastic hook from the ring-shaped groove, and then a square bar body with the required length needs to be inserted into the inner square bar body; and accordingly, the inner square bar body and the outer square bar bod can be freely mounted, dismounted and combined, thereby achieving the application to different door thicknesses and then reducing the cost.

Description

technical field [0001] The invention relates to the field of locks, more specifically, it relates to a plug-type connecting square bar structure. Background technique [0002] At present, smart locks are becoming more and more popular in the market. Most of the lock body functions are double-fast functions. Only a square rod is installed between the lock body and the handle. Synchronous action, the disadvantage of this lock body structure using a square rod is that the lock can be opened from the outside with a peephole unlocking tool, which is very unsafe. [0003] With the improvement of technology, the current lock body is designed as an anti-cat eye lock body, so that the inner and outer handles will not move synchronously when opening the door. Divide the square rod into two. When the door is unlocked, the outer handle drives the outer rod, and the outer rod drives the fork on the outer layer of the lock to unlock. When the door is unlocked, the inner handle drives the...

[0002] At present, smart locks are becoming more and more popular in the market. Most of the lock body functions are double-fast functions. Only a square rod is installed between the lock body and the handle. Synchronous action, the disadvantage of this kind of lock body structure using a square rod is that the lock can be opened from the outside with the cat's eye lock tool, which is very unsafe

[0003] With the improvement of technology, the current lock body is designed as an anti-cat eye lock body, so that the inner and outer handles will not move synchronously when opening the door. Divide the square rod into two. When the door is unlocked, the outer handle drives the outer rod, and the outer rod drives the fork on the outer layer of the lock to unlock. When the door is unlocked, the inner handle drives the inner rod, and the inner rod drives the inner layer of the lock. The fork realizes unlocking. When you go out, you only need to turn the anti-peephole safety button inside the door to the locked position, and the inner handle cannot be pressed, so the peephole tool cannot open the door.

[0004] In practical application, the existing inner and outer square rods are riveted as a whole, and the inner and outer square rods can rotate relative to each other. Due to the wide variety of door thickness specifications on the market, and the length specifications of the other rods also require changes, in order to meet market requirements, generally in Several lengths of square rods riveted as a whole will be provided during delivery, and the desired length specification can be selected according to the needs during installation, but this method wastes a lot and virtually increases its use cost
