Abstract

The utility model discloses a special plastic pipe, belonging to the technical field of plastic pipes. The plastic pipe is similar to the ordinary plastic pipes in terms of appearance, has an external wall and an internal wall and is characterized in that the internal wall is provided with a plurality of longitudinal ribs. The utility model is simple and novel in structure. The role of the ribs are equal to the arrangement of steel bars onto the plastic pipe, which increases the strength of the plastic pipe without bringing any negative impact, so that the plastic pipe has a good bending ability. Compared with the ordinary plastic pipes, in the circumstance of the same mass, the anti-bending ability of the plastic pipe of the utility model is a plurality of times stronger than the ordinary plastic pipes.

Description

Profiled tubes consisting of synthetic material

The utility model relates to the plastic tube technical field.

Plastic tube has light weight, pliability is good, performances such as cost is low, so be widely used in a lot of fields, along with social development, technology is constantly progressive, people are requiring plastic tube to have the flexible while, also require it should have suitable intensity, people have taked multiple measure for this reason, for example increase pipe thickness, use high-strength polyethylene raw material etc., but these measures or increased fabricating cost, or only increased a little intensity, can not adapt to the use of particular surroundings, for example, when the aquaculture net box of the deep-sea of the coastal used for aquiculture of making, tubing is in the bending process or meet with and marinely bending takes place when clashing into than high sea easily or squeeze flat phenomenon, cause and do over again or scrap, therefore people carry out special processing to the PE plain edition tubing of the Φ 200-350mm of use, or increase wall thickness, or take biexhaust pipe, or the pipe in the filling waste material, but effect is all undesirable, so is badly in need of a kind of light weight on the market, pliability is good, the bending resistance of anti-folding, plastic tube with low cost is for people to use.

The purpose of this utility model is intended to improve above-mentioned deficiency, and a kind of good pliability that both had is provided, and has bending resistance folding endurance preferably again, and profiled tubes consisting of synthetic material simple in structure, easy to make.

The purpose of this utility model realizes by following proposal, a kind of profiled tubes consisting of synthetic material, and its profile is similar to plain end pipe, has pipe outer wall, inner tube wall, and its special way is to be provided with several longitudinal ribs on inner tube wall.The shape of rib can be designed to multiple pattern, and convenient according to varying strength demand and Mould Machining, its transverse section can be square, trapezoidal, circular arc multiple geometrical shapies such as (arches).

In order to gain in strength, can also in pipe, add inner sleeve again, inner sleeve fixedly abuts against with rib, watches similar big pipe box tubule outward, adopts several ribs to connect between two pipes.

The utility model is simple in structure, novel, and the effect of rib is equivalent to add reinforcing bar to plastic tube, neither influences the pliability of pipe, has increased intensity again.Make pipe have good bend resistance performance, compare with common plastics tube, under the situation of same quality, its bend resistance intensity can improve several times.

Below in conjunction with drawings and Examples the utility model is explained further.

Description of drawings:

Fig. 1-structural representation of the present utility model;

Fig. 2-second kind of structural representation of the present utility model;

Fig. 3-the third structural representation of the present utility model.

The explanation of accompanying drawing drawing:

1 pipe outer wall, 2 inner tube walls, 3 ribs, 4 inner sleeves.

Embodiment 1

With reference to figure 1, plastic tube adopts common PE material, and it has pipe outer wall 1, inner tube wall 2,8 trapezoidal longitudinal ribs 3 evenly are set on inner tube wall 2, rib 3 is fixed on the inner tube wall 2, and for easy to make, rib 3 can adopt the mould single injection-molded with pipe.

Embodiment 2

With reference to figure 2, the plastic tube structure is substantially the same manner as Example 1, it has pipe outer wall 1, inner tube wall 2, on inner tube wall 2, evenly be provided with 8 arc longitudinal ribs 3, it also is provided with an inner sleeve 4, and the tube wall of inner sleeve 4 is fixed on the rib 3, for easy to make, outer tube, rib 3, inner sleeve 4 also can adopt the Shooting Technique time processing to form, and can make whole plastic tube more solid like this.Present embodiment is compared with embodiment 1, and the warping resistance intensity of plastic tube is higher, is fit to use under high standard, the particular surroundings.

In order to satisfy the special requirement of higher standard, several ribs 3 also can be set on the inwall of inner sleeve 4, structure is improved the warping resistance intensity of plastic tube more as shown in Figure 3.

From the foregoing description as can be seen, the quantity of rib of the present utility model, inner sleeve can increase or reduce according to different needs, within the prepared structure subordinate protection domain of the present utility model.

The utility model has only changed the geometry of plastic pipe inner wall, is not changing plastic tube profile, pipe Protonatomic mass only increases the warping resistance intensity that has improved pipe in a little the situation, with existing increase thickness of pipe wall The measures such as degree, raising material quality are compared, and have simple in structure, with low cost, intensity advantages of higher, It is a kind of more satisfactory plastic pipe.
