Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-3, the present invention provides a quick connector for cable ducts, comprising: the connector comprises a connector body 1 and elastic clamping jaws 2;
the connector body 1 is provided with a cavity 11 inserted with the cable guide pipe 3, and the elastic clamping jaws 2 are fixedly connected with the inner wall of the cavity 11; the elastic claw 2 comprises a circular ring 21 and a plurality of elastic sheets 22 which are distributed at intervals along the circumferential direction, one end of each elastic sheet 22 is connected with the circular ring 21, and the other end of each elastic sheet 22 is a free end and gradually approaches to the central axis of the cavity 11 along the insertion direction of the cable guide 3;
the diameter of the ring 21 is larger than the diameter of the cable guide 3 and the diameter of the circumference enclosed by the free end is smaller than the diameter of the cable guide 3.
The quick coupler of the cable guide pipe 3 has the advantages that through the arrangement of the elastic clamping jaws 2, when the guide pipe 3 is inserted into the quick coupler, the elastic sheets 22 of the elastic clamping jaws 2 can be opened, so that the guide pipe can smoothly enter the quick coupler; when the conduit 3 is pulled out from the quick connector, the conduit 3 drives the elastic sheet 22 to contract, the elastic sheet 22 and the conduit 3 form interference fit, the larger the outward pulling force of the conduit 3 is, the more the elastic sheet 22 contracts, the larger the friction force between the elastic sheet 22 and the conduit 3 is, and therefore the conduit 3 can not fall off from the quick connector under the action of external force.
In this embodiment, for mounting the elastic jaws 2, the chamber 11 is divided into a first portion 111 and a second portion 112 communicating with each other along the insertion direction of the cable guide 3; the first portion 111 has a larger diameter than the second portion 112; the inner wall of the first portion 111 is provided with a slot along the circumferential direction for fixing the ring 21.
In this embodiment, the joint body 1 is provided with two cavities 11. In this way, two lengths of conduit 3 can be inserted. As a simple alternative, the number of chambers 11 may also be increased further as required. And the included angle between chamber 11 and chamber 11 also can set by oneself according to actual conditions, and two chambers 11 are 180 degrees contained angle in this embodiment.
In addition, in order to realize that the conduit 3 and the quick coupler can be separated when the conduit needs to be disassembled and assembled, in the embodiment, the quick coupler further comprises a push ring 4 movably connected with the opening of the cavity 11, and the upper end 41 of the push ring 4 along the central axis of the cavity is exposed out of the coupler body 1; the lower end 42 of the push ring 4 along the central axis of the chamber falls on the spring plate 22 along a projection parallel to the central axis of the chamber.
