Description

Technical Field

[0001] This utility model relates to MPP pipes, and more particularly to an MPP pipe that is easy to splice. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, is divided into open-cut and trenchless types. MPP trenchless pipe is also known as MPP jacking pipe or drag pipe. MPP pipe uses modified polypropylene as the main raw material and has the characteristics of high temperature resistance and external pressure resistance. It is suitable for medium and low voltage power transmission cable ducts below 10KV.

[0003] However, the current MPP pipes have some shortcomings. Due to their limited length, multiple MPP pipes need to be spliced ​​together when used. However, when splicing MPP pipes, the two spliced ​​MPP pipes cannot be limited, so the MPP pipes will rotate at an angle after splicing, which is not conducive to subsequent splicing and installation. Utility Model Content

[0004] The main purpose of this invention is to provide an MPP tube that is easy to splice, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An MPP pipe that is easy to splice includes a pipe body, a plug, a first limiting plate, and a second limiting plate. The plug is movably embedded on the surface of the pipe body and at the front end. The first limiting plate is movably installed on the front surface of the plug, and the second limiting plate is movably installed on the rear surface of the plug.

[0007] More preferably, the tube body has a docking groove on its surface and at its rear end, a slot numbered 1 is formed on the lower inner surface of the docking groove and at its rear end, a storage groove is formed on the surface of the tube body and at its front end, a limiting sliding groove is formed on both inner sides of the storage groove, and a slot numbered 2 is formed on the lower inner surface of the storage groove near the front end.

[0008] More preferably, the front and rear surfaces of the insert block are provided with lifting grooves longitudinally near both sides, and the two side surfaces of the insert block are fixedly installed with limit sliders at the rear.

[0009] More preferably, lifting blocks are fixedly installed on the rear surfaces and near the upper sides of the second and first limiting plates, the lifting blocks are embedded in the lifting grooves, and the second and first limiting plates are movably connected to the insert blocks through the lifting blocks.

[0010] More preferably, the lower end of the second limiting plate is embedded in the second slot, the insert is movably embedded in the storage groove, the limiting slider is embedded in the limiting groove, and the insert is movably connected to the tube body through the limiting slider.

[0011] More preferably, the number of the storage slots and docking slots is four, and the four storage slots and docking slots are distributed in a matrix.

[0012] More preferably, the length of the insert is less than the length of the receiving groove and the docking groove.

[0013] Compared with the prior art, this utility model proposes an MPP tube that is easy to splice, which has the following beneficial effects:

[0014] In this invention, by setting up a tube body, a plug block, a first limiting plate, and a second limiting plate in a cooperative manner, when two MPP tubes need to be spliced ​​together, the plug block is pushed forward so that it is embedded in the docking groove of the other tube body. Then, the first limiting plate and the second limiting plate are pressed down so that the first limiting plate is embedded in the first slot of the other tube body, and the second limiting plate is embedded in the second slot. In this way, the angle of the two spliced ​​tube bodies can be positioned, which will make the subsequent installation process more convenient. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-4 As shown, an MPP pipe that is easy to splice includes a pipe body 1, a plug 2, a first limiting plate 3 and a second limiting plate 4. The plug 2 is movably embedded on the surface of the pipe body 1 at the front end. The first limiting plate 3 is movably installed on the front surface of the plug 2, and the second limiting plate 4 is movably installed on the rear surface of the plug 2.

[0022] Furthermore, a docking groove 101 is provided on the surface of the tube body 1 at the rear end, and a slot 102 is provided on the lower inner surface of the docking groove 101 at the rear. A receiving groove 103 is provided on the surface of the tube body 1 at the front end, and limiting grooves 104 are provided on both inner sides of the receiving groove 103. A second slot 105 is provided on the lower inner surface of the receiving groove 103 near the front. The cooperation between the limiting grooves 104 and the limiting slider 201 can assist the insertion block 2 to move smoothly and prevent the insertion block 2 from disengaging from the receiving groove 103.

[0023] Furthermore, the front and rear surfaces of the insert 2 are provided with lifting grooves 202 in the longitudinal direction near both sides, and the two side surfaces of the insert 2 are fixedly installed with limit sliders 201 at the rear.

[0024] Furthermore, lifting blocks 401 are fixedly installed on the rear surface and near the upper sides of the second limiting plate 4 and the first limiting plate 3. The lifting blocks 401 are embedded in the lifting groove 202. The second limiting plate 4 and the first limiting plate 3 are movably connected to the insert block 2 through the lifting blocks 401. There is a certain friction between the lifting blocks 401 and the lifting groove 202, so that the first limiting plate 3 and the second limiting plate 4 will not shake due to vibration.

[0025] Furthermore, the lower end of the second limiting plate 4 is embedded in the second slot 105, the insert 2 is movably embedded in the storage groove 103, the limiting slider 201 is embedded in the limiting slide groove 104, and the insert 2 is movably connected to the tube body 1 through the limiting slider 201; the storage groove 103 can store the insert 2 when not in use. When the insert 2 of one tube body 1 is inserted into the docking groove 101 of another tube body 1, the first limiting plate 3 and the second limiting plate 4 are pressed down, which can connect the two tube bodies 1 together, thus facilitating subsequent installation operations.

[0026] Furthermore, there are four storage slots 103 and four docking slots 101, which are arranged in a matrix.

[0027] Furthermore, the length of the insert 2 is less than the length of the receiving groove 103 and the docking groove 101.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
