Description

A kind of flexible pipe structure

Technical field

This utility model relates to a kind of spider, particularly a kind of flexible pipe structure.

Background technology

Spider telescopic leg structure of the prior art, it is by turning (rotation) lock sleeve, Thus drive retaining ring to unclamp and locking state, and in the loosened condition, the tail end of a upper joint muscle pipe Muscle inner telescoping tube can be saved at next, now go up meeting phase mutual friction between a pipe joint with next pipe joint, And hang between the muscle pipe caused and muscle pipe and damage, damage product appearance.

Summary of the invention

The purpose of this utility model is contemplated to the weak point avoided in background technology, it is provided that one Planting flexible pipe structure, it has the friction avoided between a joint muscle pipe and next joint muscle pipe.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that a kind of telescoping tube knot Structure, including the most end to end some muscle pipes, the tail end wherein going up a joint muscle pipe can be at next Joint muscle inner telescoping tube, and head end of next joint muscle pipe be provided with can a joint muscle pipe on positioning and locking Locking mechanism, is characterized in that: described locking mechanism includes lock sleeve, retaining ring, adapter sleeve, Adapter sleeve is sheathed on and saves outside the head end end of muscle pipe with next, and its radial outside is provided with outer spiral shell Stricture of vagina, is provided with axial bell inside its upper end, the tail end of a described upper joint muscle pipe runs through retaining ring And stretch in the pipe of next joint muscle pipe, the radial outside of described retaining ring is provided with axial conical section, Axially conical section is connected with axial bell, is provided with on front side of the lower end of axial conical section Extension set, this extension set can be inserted in the pipe of next joint muscle pipe, and described lock sleeve is sheathed on lock The radial outside of tight ring, its lower end inside is provided with female thread, is provided with button portion, institute inside its upper end State and outside the upper end of retaining ring, be provided with groove portion, button portion and groove portion snapping, female thread and external thread rotary Connect.

For a kind of optimization of the present utility model, a upper joint muscle pipe tail end end radial outside is sheathed There is anti-turn-taking, be connected by the anti-inwall radial rotation turn-taked with next joint muscle pipe.

For a kind of optimization of the present utility model, the radial outside of lock sleeve is arranged with rubber sleeve.

For a kind of optimization of the present utility model, the radial outside rear and front end of described lock sleeve is divided Not being provided with latch closure, described rubber sleeve is sheathed on the lock sleeve outer wall between the latch closure of rear and front end.

This utility model, compared with background technology, has by turning (rotation) lock sleeve, Thus drive retaining ring to unclamp and locking state, due to the axial conical section lower end of retaining ring Front side is provided with extension set, during retaining ring can be inserted into muscle pipe in locking state, is avoided that one Joint muscle pipe directly contacts with next joint muscle pipe thus produces friction, thus plays outside protection muscle pipe Wall is damaged from extension；This locking mechanism also can play increase locking force simultaneously, can allow foot tube more Adding stable, locking force is more preferable, and avoids muscle pipe locking and under half releasing orientation, can Prevent the friction between muscle pipe and muscle pipe.

Detailed description of the invention

Embodiment 1: with reference to Fig. 1～8.A kind of flexible pipe structure, including some head and the tail phases successively The muscle pipe connect, the tail end wherein going up a joint muscle pipe 6 can be flexible in next joint muscle pipe 5, and under The head end of one joint muscle pipe 5 is provided with can the locking mechanism 8 of a joint muscle pipe 6, institute on positioning and locking Stating locking mechanism 8 and include lock sleeve 2, retaining ring 3, adapter sleeve 4, adapter sleeve 4 is sheathed on Outside the head end end of next joint muscle pipe 5, its radial outside is provided with external screw thread 41, on it Being provided with axial bell 42 inside end, the tail end of a described upper joint muscle pipe 6 runs through retaining ring 3 And stretch in the pipe of next joint muscle pipe 5, the radial outside of described retaining ring 3 is provided with axial taper Section 32, axial conical section 32 is connected with axial bell 42, axial conical section 32 Being provided with extension set 33 on front side of lower end, this extension set 33 can be inserted into next joint muscle pipe 5 In pipe, described lock sleeve 2 is sheathed on the radial outside of retaining ring 3, in its lower end inside is provided with Screw thread 22, is provided with button portion 23, is provided with groove outside the upper end of described retaining ring 3 inside its upper end Portion 31, button portion 23 and groove portion 31 snapping, female thread 22 spins with external screw thread 41.Upper one Joint muscle pipe 6 tail end end radial outside is arranged with anti-turn-takes 7,7 is saved with next by anti-turn-taking The inwall radial rotation of muscle pipe 5 connects.The radial outside of lock sleeve 2 is arranged with rubber sleeve 1. The radial outside rear and front end of described lock sleeve 2 is respectively equipped with latch closure 21, described rubber sleeve 1 On lock sleeve 2 outer wall being sheathed between rear and front end latch closure 21.

It is to be understood that: although this utility model is contrasted specifically by the present embodiment Bright, but these explanations, simply to simple declaration of the present utility model rather than to this practicality Novel restriction, any without departing from the innovation and creation in this utility model connotation, each fall within In protection domain of the present utility model.
