The utility model aims at providing an elasticity wall bushing, under the inhomogeneous condition in wall hole, deformation can take place for sleeve pipe self to accomplish sheathed tube smooth installation, the sleeve pipe after the installation possesses locking function simultaneously under receiving the spring action.

Description

Elastic wall bushing

Technical Field

The utility model relates to an elasticity wall bushing.

Background

The wall bushing is a common building material, the existing wall bushing is generally in a circular tube shape, and two ends of the bushing are provided with end covers; when people need to arrange electric wires, gas pipes or water pipes, the wall body is punched firstly, then the sleeve is inserted into the wall hole, and then the electric wires, the gas pipes or the water pipes are inserted into the sleeve, so that the purposes of moisture prevention, extrusion resistance and wear resistance are achieved. And at the in-process that the wall body punched, the wall hole was inhomogeneous most of the time, and the sleeve pipe is very difficult to insert the wall downthehole, needs expand the wall hole very big, and can lead to the sleeve pipe installation too loose like this.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide an elasticity wall bushing, under the inhomogeneous condition in wall hole, deformation can take place for sleeve pipe self to accomplish sheathed tube smooth installation, the sleeve pipe after the installation possesses locking function simultaneously under receiving the spring action.

In order to realize the above purpose, the utility model adopts the technical scheme that: it includes sleeve pipe and end cover, and the quantity of end cover is two and sets up both ends about the sheathed tube respectively, and the middle part of end cover is provided with the round hole, and the symmetry is provided with the elastic section of two inside recesses on the sheathed tube pipe wall, when the inhomogeneous of wall hole brill, alternates the sheathed tube in-process and can meet the resistance that the side brought, and elastic section can take place deformation this moment to avoid the inhomogeneous condition that leads to being difficult to the installation of wall hole.

The utility model provides an elasticity section can regard as preferred mode for the V font structure.

The utility model is convenient for installing the end cover on the sleeve; preferably, be provided with two at least to the socket strip in sheathed tube pipe wall inboard, be provided with to the jack hole on the socket strip, the end cover includes the end plate, and the terminal surface of end plate is provided with to inserted block and stopper, to inserted block and adopt interference fit between the jack hole, the stopper be the arc and with sleeve pipe inside wall elastic contact.

The utility model discloses an it is the triangle-shaped structure to the jack-hole with to the inserted block, as the preferred structure to inserting, easy to assemble.

The utility model discloses a to the socket strip with be two that the symmetry set up to the inserted block, as the preferred structure of end cover installation on the sleeve pipe, easy to assemble.

The utility model provides a quantity of stopper is four and distributes respectively in the left and right sides to the inserted block, as a spacing preferred structure, has made things convenient for the installation of end cover.

The utility model has the advantages that: the utility model provides an elasticity wall bushing, under the inhomogeneous condition in wall hole, deformation can take place for sleeve pipe self to accomplish sheathed tube smooth installation, the sleeve pipe after the installation possesses locking function simultaneously under receiving the spring action.
