Description

Technical Field

[0001] This utility model relates to the field of MPP cable protection pipe technology, specifically a straight-joint MPP cable protection pipe. Background Technology

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

[0003] When using MPP cable protection pipes, it is necessary to splice and fix multiple pipes together. Traditionally, this requires specific tools and the cooperation of multiple people to install the installation accessories between the pipes to form a fixed splice, which makes the installation relatively troublesome. In addition, the fixed ring structure does not have the structure for adjusting direction and position, which restricts the position during splicing and affects the overall installation efficiency. Utility Model Content

When using current MPP cable protection pipes, multiple pipes need to be spliced ​​and fixed together. Traditionally, this requires specific tools and the cooperation of multiple people to install the installation accessories between the pipes to form a fixed splice, which makes the installation relatively troublesome. In addition, the fixed ring structure does not have the structure for adjusting direction and position, which restricts the position during splicing and affects the overall installation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A straight-joint MPP cable protection pipe includes a main protection pipe, a sleeve ring body fitted to the outer side of the main protection pipe, rotating side blocks symmetrically snapped onto the top and bottom surfaces of the sleeve ring body, horizontally and symmetrically welded extension side blocks to the outer side of the sleeve ring body, symmetrically formed mating side grooves on both sides of the extension side blocks, through holes on the sides of the extension side blocks, symmetrically formed snap-fit ​​side grooves on both sides of the extension side blocks, and a plug-in connecting block inserted into the end of the extension side block away from the sleeve ring body. A limiting inner groove is symmetrically formed on the top and bottom surfaces of the inner side of the sleeve ring body. The inner side of the limiting inner groove is engaged with an extrusion inner plate. The extension side block has an end mounting groove at the end away from the sleeve ring body. The outer arc surface of the extrusion inner plate has a mating screw hole. The inner arc surface of the extrusion inner plate is fixedly bonded with an anti-slip rubber plate. The inner side wall of the sleeve ring body is symmetrically inserted with extrusion screws. The inner side wall of the sleeve ring body has a ring retaining groove. The outer side of the extrusion screw is welded with a positioning ring. The two sides of the insertion connecting block are symmetrically provided with locking side grooves. The opening end of the locking side groove is engaged with a snap-fit ​​wedge. The inner side of the locking side groove is engaged with a support spring.

[0007] In a preferred embodiment of this utility model, there are multiple sleeve rings, and the specifications and dimensions of the multiple sleeve rings are all set in the same way. The multiple sleeve rings are arranged in parallel with each other. The rotating side blocks are symmetrically snapped into the center line of the top and bottom surfaces of the sleeve rings, and one end of the rotating side block is fixedly sleeved into the extension end of the extrusion screw.

[0008] In a preferred embodiment of this utility model, the mating side grooves are symmetrically opened at the center of the two symmetrical sides of the extension side block, and the through holes are all opened through the sides of the extension side block near the edge, and the extension ends of the through holes all extend into the interior of the mating side grooves to maintain connection.

[0009] In a preferred embodiment of this utility model: the through end of the snap-fit ​​side groove extends into the interior of the end mounting groove to maintain communication; there are multiple plug-in blocks, and the specifications and dimensions of the multiple plug-in blocks are set in a consistent manner; the two ends of the plug-in blocks are horizontally plugged into the interior of two adjacent end mounting grooves; the end mounting groove is opened at the center of one end of the extended side block.

[0010] In a preferred embodiment of this utility model: the mating screw hole is opened at the center of the outer arc surface of the extrusion inner plate, the side of the anti-slip rubber plate is extruded and set on the outer side of the main protective tube, one end of the extrusion screw extends to the inner side of the limiting inner groove, and the extension end is threaded and set on the inner side of the mating screw hole.

[0011] In a preferred embodiment of this utility model: the positioning ring is horizontally snapped into the inner side of the ring groove, the snapping side grooves are symmetrically opened on both sides of the center line of the plug-in block near both ends, one end of the snapping oblique block is connected to one end of the support spring, and the other end is correspondingly snapped into the inner side of the snapping side groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows the main protective tubes to be placed horizontally or stacked vertically. When these tubes are arranged, the sleeve ring can be pushed to a designated position, allowing the ends of the extended side blocks to align horizontally. Before alignment, the connecting block is inserted into the end mounting groove. Supported by the spring, the snap-fit ​​oblique block is correspondingly snapped into the snap-fit ​​side groove and fixed, forming a fixed connection between the ends of the two extended side blocks. This allows the sleeve ring to be fixedly assembled. Rotating the rotating side block then drives the extrusion screw to rotate, causing the extrusion screw to push the inner plate towards the main protective tube. The outer edge of the protective pipe moves, causing the anti-slip rubber plate to be pressed and fixed on the outer edge of the main protective pipe, forming a direct splicing installation between two adjacent main protective pipes. When it is necessary to fix the assembled pipe body, the fixing rod end can be inserted into the corresponding mating side groove, and the bolt is used to fix the connection through the through hole and the through hole at the end of the connecting rod. The connection is stabilized under the fixed support of the connecting rod. The movable splicing installation allows for adjustment according to the required installation point, and the snap-fit ​​connection makes the installation more convenient and efficient.
