Quick-plug connector connecting structure

Abstract

The invention provides a quick-plug connector connecting structure comprising a mounting head, outer baffles, sliding grooves, knobs, driving conical surfaces, anti-sliding grooves, pressing plates, driven conical surfaces, spring grooves, pressing anti-slip patterns, nylon tubes and annular springs; the inner part of the mounting head is slidably connected with a plurality of groups of pressing plates; the outer sides of the pressing plates are elastically pressed with a group of annular springs; a group of nylon tubes are connected between the pressing plates and the mounting head in a pressing way; and the top of the mounting head is in threaded connection with a group of knobs. According to the quick-plug connector connecting structure, the pressing plates are pulled outwards through the cooperation of the knobs and the conical surfaces of the pressing plates, so that the nylon tubes are fixed, meanwhile, the nylon tubes are well fixed by arranging the pressing anti-slip patterns,the fixing strength is high, the nylon tubes are not easy to detach, simultaneously, damage to the nylon tubes is avoided, the risks of taking-off and cracking of the nylon tubes are greatly reduced,the operation is simple in the using process, and the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of connection components, and more specifically relates to a connection structure of a push-in joint. Background technique [0002] Nylon tube has great stability in wear resistance, tensile and bending properties, and is easy to install. Its good comprehensive performance is unmatched by copper tube, steel tube and rubber tube. It is an ideal material to replace copper, steel and rubber. During the connection of nylon tubes, nylon tube quick-plug connectors are generally used for connection. [0003] Based on the above, the existing push-in connectors use barb thorns for internal connection. When connecting, the barbs will scratch the body to a certain extent. At the same time, the connecting parts are weak against lateral force during use. There is a risk of detachment of the connected parts and the connection strength is low. [0004] Therefore, in view of this, researches and improvements are made on t...
