Description

Prevent outer wall of inner tube from scratching structure between a kind of flexible pipe fitting

Technical field

The utility model belongs to electric tail gate correlative technology field, and in particular to prevents outer wall of inner tube between a kind of flexible pipe fitting Scratch structure.

Background technique

As China's automobile industry continues to develop, electric tail gate is stepped up as the aptitude manner that automobile tail gate is opened Above car, and electric tail gate is supported using metal (iron pipe) outer tube at present, and pipe fitting need to do paint layer and be protected, and pipe fitting exists Inside and outside telescopic process, friction will cause internal pipe fitting paint layer from surface and scratch between two pipes, so as to cause bad order, further cause Pipe fitting gets rusty etc. bad.

Utility model content

The purpose of this utility model is to provide preventing outer wall of inner tube from scratching structure between a kind of flexible pipe fitting, telescoping tube is solved Outer wall of inner tube is scraped off paint layer from surface problem between part.

To achieve the above object, the utility model provides the following technical solutions: preventing outer wall of inner tube between a kind of flexible pipe fitting Structure, including inner and outer tubes, said inner tube and outer tube sliding contact are scratched, said inner tube is mounted on the inside of outer tube；

Said inner tube includes extra heavy pipe, tubule, inner tube convex ribs and inclined-plane, and one end of inner tube is arranged in the extra heavy pipe, described thin The other end of inner tube is arranged in pipe, and several groups said inner tube convex ribs isogonism is distributed on the end circumference of tubule, and the inclined-plane is set It sets between extra heavy pipe and tubule；The outer tube includes the first convex ribs of outer tube and outer tube convex ribs, the first convex ribs of outer tube described in several groups Isogonism is distributed on outer tube wall circumference, and the side of the first convex ribs of outer tube described in several groups is arranged in the outer tube convex ribs, described One end of outer tube is arranged at nozzle in outer tube convex ribs.

Compared with prior art, the utility model has the beneficial effects that

1, the utility model inner and outer pipes telescopic process, outer wall of inner tube will not be generated with outer tube wall and directly be contacted, stretch Journey relies primarily on inner tube convex ribs part and contacts with outer tube, and friction part is the convex rib part, not will cause outer wall of inner tube damage phenomenon.

2, part is improved using source, not will increase part processing charges, and greatly reduces production and appearance is not after sale It is good, enterprise's production cost and after-sales service cost can be substantially reduced.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: preventing outer wall of inner tube from scratching between a kind of flexible pipe fitting Structure, including inner tube 1 and outer tube 2, said inner tube 1 and 2 sliding contact of outer tube, said inner tube 1 are mounted on the inside of outer tube 2.

Specifically, said inner tube 1 includes extra heavy pipe 101, tubule 102, inner tube convex ribs 103 and inclined-plane 104, the extra heavy pipe 101 One end of inner tube 1 is set, and the other end of inner tube 1,103 isogonism of several groups said inner tube convex ribs point is arranged in the tubule 102 On the end circumference of tubule 102, the inclined-plane 104 is arranged between extra heavy pipe 101 and tubule 102 cloth.

Specifically, the outer tube 2 includes the first convex ribs of outer tube 201 and outer tube convex ribs 202, outer tube first described in several groups is convex 201 isogonism of muscle is distributed on 2 inner wall circumference of outer tube, and the first convex ribs of outer tube 201 described in several groups are arranged in the outer tube convex ribs 202 Side, one end of outer tube 2 is arranged at nozzle in the outer tube convex ribs 202.

As shown in Figure 2-5, the tubule 102 in inner tube 1 is mounted in outer tube 2 through the first convex ribs of outer tube 201 on outer tube 2 Portion, the inner tube convex ribs 103 in inner tube 1 are contacted with the inner wall of outer tube 2.

Working principle: the tubule 102 in inner tube 1 is mounted on the inside of outer tube 2 through the first convex ribs of outer tube 201 on outer tube 2, Inner tube convex ribs 103 in inner tube 1 are contacted with the inner wall of outer tube 2, inner tube 1 and 2 sliding contact of outer tube, in inner and outer pipes telescopic process, The outer wall of inner tube 1 will not be generated with the inner wall of outer tube 2 and directly be contacted, and telescopic process relies primarily on 103 part of inner tube convex ribs and outer Pipe 2 contacts, and friction part is 103 part of inner tube convex ribs, not will cause the outer wall damage phenomenon of inner tube 1.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
