Description
Technical field：
It the utility model is related to building auxiliary equipment technical field, and in particular to a kind of plastic expansion pipe.
Background technology：
At present, plastic expansion pipe is often used in construction and decoration field, its main function is to play to strengthen stable fixed work
With existing plastic expansion pipe, although the annexation of enhancing between the two is served to a certain extent, for some special necks
Domain, when particularly connector is heavier or during two connector right angle settings, because stress is larger, causes plastic expansion pipe to come off, cause
Two connector Joint failures.
Utility model content：
The purpose of this utility model is exactly to make up the deficiencies in the prior art, there is provided a kind of plastic expansion pipe, it has
Bilayer connection, more firm, simple in construction, low cost and other advantages are connected, solve problems of the prior art.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of plastic expansion pipe, including outer layer plastic wall, outer layer plastic wall is interior to be provided with inner plastic wall, inner plastic wall one end
Provided with opening, the cavity of closing is provided between inner plastic wall and outer layer plastic wall, is provided with glue in cavity, on outer layer plastic wall
Portal provided with some glue, the sealing of the glue place of portalling is provided with membrane wall.
The outer layer plastic wall outer wall is provided with some projections.
Some demarcation strips are provided between the inner plastic wall and outer layer plastic wall, if cavity is separated into by the demarcation strip
Dry areola.
The outer layer plastic wall is provided with rubber seal close to one end of opening.
The rubber seal is frustum cone structure.
The outer layer plastic wall and inner plastic wall are made up of polyethylene or nylon material.
The inner plastic wall inwall is provided with screw thread, and screw thread is connected with expansion bolt.
The utility model uses such scheme, for deficiency existing for existing plastic dowel sleeve, devises a kind of plastic expanding
Pipe, by the way that plastic expansion pipe is designed into outer layer plastic wall and inner plastic wall double-layer structure, and cavity is formed, glue is set in cavity
Water, outer layer plastic wall, which is provided with, to portal, and the place of portalling is provided with membrane wall, realizes when expansion bolt is screwed into inner plastic wall, is pressing
In the presence of power, the glue in cavity breaks through membrane wall, into the gap between outer layer plastic wall and connector, so as to play
Strengthen the connection of connector and plastic expansion pipe；It is raised by being designed on outer layer plastic wall, effectively strengthen outer layer plastic wall and company
Coefficient of friction between fitting, increasing friction force；By designing rubber seal, can not only play prevents glue from flowing out, and
And effectively strengthen sealing and fastness.
Brief description of the drawings：
Fig. 1 is the utility model structure diagram；
Fig. 2 is A-A views in the utility model Fig. 1；
Wherein, 1, outer layer plastic wall, 2, inner plastic wall, 3, opening, 4, cavity, 5, glue, 6, glue portal, 7, film
Wall, 8, raised, 9, demarcation strip, 10, areola, 11, rubber seal, 12, expansion bolt.
Embodiment：
The utility model is described further with embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1-2, a kind of plastic expansion pipe, including outer layer plastic wall 1, outer layer plastic wall 1 is interior to be provided with inner plastic wall
2, the one end of inner plastic wall 2 is provided with opening 3, and the cavity 4 of closing, cavity 4 are provided between inner plastic wall 2 and outer layer plastic wall 1
Interior to be provided with glue 5, outer layer plastic wall 1 portals 6 provided with some glue, and glue sealing at 6 of portalling is provided with membrane wall 7, pass through by
Plastic expansion pipe is designed to outer layer plastic wall 1 and the double-layer structure of inner plastic wall 2, and forms cavity 4, and glue 5 is set in cavity 4,
Outer layer plastic wall 1, which is provided with, portals 6, portals and sets membrane wall 7 at 6, realizes when expansion bolt 12 is screwed into inner plastic wall 2,
In the presence of pressure, the glue 5 in cavity 4 breaks through membrane wall 7, into the gap between outer layer plastic wall 1 and connector, from
And play the connection of enhancing connector and plastic expansion pipe.
The outer wall of outer layer plastic wall 1 is provided with some raised 8, strengthens the coefficient of friction between outer layer plastic wall 1 and connector,
And then prevent from coming off.
Some demarcation strips 9 are provided between inner plastic wall 2 and outer layer plastic wall 1, cavity 4 is separated into some by demarcation strip 9
Areola 10, some areolas 10 are separated into, make its stress bigger, it is easier to break through membrane wall 7, glue 5 more uniformly enters
Enter between connector and outer layer plastic wall 1 in gap.
Outer layer plastic wall 1 is provided with rubber seal 11 close to one end of opening 3, and while preventing that glue 5 from flowing out, increase is outer
Connection between layer plastic wall 1 and connector.
Rubber seal 11 is frustum cone structure, and it is easy to make it into connector, and is extracted difficult therefore easy for installation same
When, effectively prevent plastic expansion pipe from coming off.
Outer layer plastic wall 1 and inner plastic wall 2 are made up of polyethylene or nylon material.
The inwall of inner plastic wall 2 is provided with screw thread, and screw thread is connected with expansion bolt 12.
It is of the present utility model as follows using process：
Punch on wall, then by the plastic expansion pipe patchhole of the application, subsequently twist expansion bolt 12 first
Enter in inner plastic wall 2, with being screwed into for expansion bolt 12 so that the glue 5 in cavity 4 is under pressure, and glue 5 is in pressure
The membrane wall 7 that glue portals at 6 is broken through under effect, glue 5 flows out out of cavity 4, between wall and outer layer plastic wall 1
In gap, so as to play more preferable fixed plastics tube expansion.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within guarantor of the present utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
