This plastics expansion pipe is through going into the screw soon in the expansion pipe main part, makes expansion pipe main part head and tail end expand because of pulling, causes the expansion pipe main part inflation, realizes and the inseparable laminating between the wall to under the effect of a plurality of enhancement connecting portion, make to connect more firm, inseparabler, overall function is perfect, and the practicality is strong.

Description

Plastic expansion pipe

Technical Field

The utility model relates to an expansion nail technical field, more specifically say, it relates to a plastics expansion pipe.

Background

The plastic expansion pipe is used for the wall-entering part of an expansion screw, is also called as a wall-entering expansion colloidal particle, has the characteristics of good elasticity, large tension, impact resistance, no fracture, strong hardness, no rust and large elasticity, is formed by injection molding of PP, PA and PE materials, and is suitable for fixing products on concrete solid and hollow walls, gypsum boards, compact natural stone materials, bottom plates, support plates, brackets, railings, windows, doors, curtain walls, machines, girders, stringers, stairs, exterior wall decorations, electrical equipment accessories and the like.

At present, the existing plastic expansion pipe is usually added with a tooth block or other limiting structures on the outer wall of the pipe body, the plastic expansion pipe can loosen in a gypsum board for a long time, the plastic expansion pipe is easily separated from the gypsum board, the fixing effect cannot be achieved, and the overall effect is not good. Therefore, the utility model provides a plastics expansion pipe.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the above-mentioned prior art, provide a plastics expansion pipe, this plastics expansion pipe has novel structure, connects firm characteristics.

In order to solve the technical problem, the purpose of the utility model is to realize like this: the utility model relates to a plastic expansion pipe, including the expansion pipe main part, the one end of expansion pipe main part is equipped with the tailboard, the left and right sides of expansion pipe main part is equipped with respectively and makes the pterygoid lamina of extension towards the tailboard direction, the expansion hole that both ends all are linked together with the external world around seting up in the expansion pipe main part sets up the guide breach of bending that is close to the middle part position on the left and right sides pore wall in expansion hole respectively, the left and right sides of expansion pipe main part has still seted up a plurality of enhancement breachs of arranging, adjacent two along its axial respectively strengthen forming one between the breach and strengthen connecting portion.

The utility model discloses further set up to: the side surface of the expansion pipe main body is provided with a plurality of anti-rotation spoke pieces which are close to the tail plate and distributed in an annular array around the axis of the tail plate.

The utility model discloses further set up to: the interval included angles between two adjacent anti-rotation spoke pieces are equal.

To sum up, the utility model discloses following beneficial effect has: the utility model relates to a plastics expansion pipe through go into the screw at the expansion pipe main part internal rotation, makes expansion pipe main part head and tail end because of pulling the expansion, causes the expansion pipe main part inflation, realize and the wall between closely laminate to under the effect of a plurality of enhancement connecting portion, make to connect more firm, inseparabler, whole function is perfect, and the practicality is strong.
