Connecting device

Abstract

The invention discloses a connecting device. A first lever and a second lever are hinged in a crossed mode and arranged in a moving cavity of an outer column, and two keys are arranged above the outercolumn and connected with a first part of the first lever and a first part of the second lever respectively. Two moving parts are arranged in corresponding moving channels respectively and connectedwith a second part of the first lever and a second part of the second lever respectively, and the first lever and the second lever enable the two moving parts to extend out to be connected with a connecting assembly through a second elastic part. The two keys press the two levers to rotate relatively, so that the two moving parts retract to be separated from the connecting assembly through first elastic parts. According to the connecting device, the principle of connecting two connecting pieces is simple, the two connecting pieces can be connected and disconnected quickly, and the connecting device is stable in connection, not prone to being lost or damaged and long in service life.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a connecting device. Background technique [0002] In order to facilitate the convenience of carrying items and the safety of items when people go out, more and more wearable devices have entered people's work and life. For example, the electronic watch can be fixed on the wrist through the strap, which is convenient for people to grasp the time; the bag, bag and other containers can be fixed on the upper body of the human body through a single or double strap, so as to avoid the influence of the bag and bag on the movement of the limbs; Connect the front and rear covers of protective cases for devices such as tablets and mobile phones to avoid structural damage caused by device collisions. [0003] In related technologies, watch straps are generally connected by elastic connecting pins at both ends, which is difficult to connect and disassemble, and the connecting pin ...

AI Technical Summary

Problems solved by technology

[0003] In related technologies, watch straps are generally connected by elastic connecting pins at both ends, which is difficult to connect and disassemble, and the connecting pin parts are easy to be lost and damaged; quick release structures such as backpack straps are generally connected by hooks inserted into the fixed ends. When the hook is deformed inward, after insertion, the hook returns to its original shape and interferes with the fixed end to generate a holding force. The low holding force caused by the deformation of the buckle is not suitable for fixing wearable devices, and the hook is easily lost due to fatigue after multiple uses. Elasticity, which makes the snap-fit ​​failure not durable, and the disassembly efficiency is low and the operation is cumbersome
