[0002] MPP power pipe is also called MPP cable pipe, MPP power cable protection pipe. The raw material is PP powder (modified polypropylene) as the main masterbatch.

[0003] However, the existing MPP cable protection pipes are generally connected and fixed by bolts when connecting the pipes. This connection method not only requires a lot of labor, but also has low installation efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a heat-resistant MPP cable protection tube, which solves the problem that in the prior art, when MPP cable protection tubes are connected between tubes, they are generally connected and fixed by bolts, which not only requires a lot of labor, but also has low installation efficiency.

[0006] The technical problem to be solved by the utility model is achieved by the following technical solutions: a heat-resistant MPP cable protection tube, comprising a plurality of tube bodies, adjacent tube bodies are connected by a connecting structure, the connecting structure comprises a plurality of embedded blocks arranged in an array at equal intervals along the circumferential direction on the outer peripheral wall of one end of the tube body, the embedded blocks are plastic blocks and one end of the embedded blocks extends out of the tube body, a plurality of connecting blocks are arranged on the outer peripheral wall of the tube body away from the embedded blocks, connecting grooves for the embedded blocks to be inserted are formed between adjacent connecting blocks, a plurality of latching teeth are arranged on the inner wall of the embedded blocks, and a plurality of latching grooves for the latching teeth to be inserted are opened on the outer peripheral wall of the tube body corresponding to the connection groove positions, wherein the latching teeth have a triangular cross-section and one end away from the other tube body to be connected thereto is a vertical surface, and the other end is an inclined surface

[0007] The utility model is further configured as follows: an embedding groove is opened on the outer wall of the connecting block and the embedding block, a binding belt for being inserted into the embedding groove is arranged in the embedding groove of an embedding block, and a fixing structure for being connected with the binding belt is arranged on a connecting block.

[0008] Specifically, the fixing structure includes a capping member arranged on the top of a connecting block, a fixing cavity for one end of a strap to be inserted into is formed between the capping member and the inner wall of the embedding groove of the connecting block, a plurality of fixing teeth 1 are arranged in an array on the bottom wall of the fixing cavity, a fixing groove is formed between adjacent fixing teeth 1, a plurality of fixing teeth 2 for being inserted into the fixing groove are arranged at one end of the binding band, a guiding inclined surface is arranged at one end of the fixing tooth 2, and a limiting plane is arranged at the other end.

[0009] The beneficial effects of the utility model are:

[0010] 1. When connecting two tubes, it is only necessary to butt the two tubes so that a plurality of inserts on one tube can be inserted into the connection groove of the other tube in sequence. The connection block limits the insert so that the two tubes cannot rotate in the circumferential direction. Moreover, since the insert is a plastic block, it has elasticity. When the insert is inserted into the connection groove, the insert expands outwards due to the abutment of the teeth against the end of the tube. When a plurality of teeth are inserted into the groove, the ends of the two tubes abut against each other. The groove limits the teeth so that the two tubes cannot be pulled outwards from each other, thereby ensuring a stable connection. The connection operation is convenient and the installation efficiency is high.

[0011] 2. After the two pipes are butt-jointed, the binding belt only needs to be rotated in a circular direction to insert the binding belt into the grooves on the surface of the connecting block and the embedding block in turn until the binding belt is inserted into the fixing cavity and then pulled out from the fixing cavity, so that the binding belt can bind the butt joint of the two pipes tightly, thereby greatly improving the connection strength of the two pipes;

[0012] 3. When the strap enters the fixed cavity, the second fixing tooth can easily enter the fixed cavity through the guiding effect of the guiding inclined surface and gradually abut against the first fixing tooth and get stuck in a number of fixing grooves, so that the installation operation of the strap is convenient, and the limiting effect of the limiting plane makes it impossible for the strap to be pulled out of the fixed cavity in the reverse direction, thereby improving the connection stability of the strap.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0020] like Figures 1 to 5 As shown, a heat-resistant MPP cable protection tube comprises a plurality of tube bodies 1, wherein adjacent tube bodies 1 are connected by a connecting structure, wherein the connecting structure comprises a plurality of embedded blocks 2 arranged in an array at equal intervals along the circumferential direction on the outer peripheral wall of one end of the tube body 1, wherein the embedded blocks 2 are plastic blocks and one end of the embedded blocks 2 extends out of the tube body 1, and a plurality of connecting blocks 3 are arranged on the outer peripheral wall of the tube body 1 away from the embedded blocks 2, and connecting grooves 4 for the embedded blocks 2 to be inserted are formed between adjacent connecting blocks 3, and a plurality of latching teeth 5 are arranged on the inner wall of the embedded blocks 2, and a plurality of latching grooves 6 for the latching teeth 5 to be inserted are provided on the outer peripheral wall of the tube body 1 corresponding to the connecting grooves 4, wherein the cross-section of the latching teeth 5 is triangular, and the end away from the other tube body 1 to be connected thereto is a vertical surface, and the other end is an inclined surface.

[0021] When connecting two tube bodies 1, it is only necessary to butt the two tube bodies 1 so that the several inserts 2 on one tube body 1 can be inserted into the connecting groove 4 of the other tube body 1 in sequence. The inserts 2 are limited by the connecting block 3 so that the two tube bodies 1 cannot rotate in the circumferential direction. In addition, since the inserts 2 are plastic blocks and thus have elasticity, during the process of the inserts 2 being inserted into the connecting groove 4, the inserts 2 will expand outwards due to the abutment of the teeth 5 against the ends of the tube bodies 1. When the several teeth 5 are all inserted into the slots 6, the ends of the two tube bodies 1 abut against each other. The teeth 5 are limited by the slots 6 so that the two tube bodies 1 cannot be pulled outwards from each other, thereby ensuring a stable connection. The connection operation is convenient and the installation efficiency is high.

[0022] like Figures 1 to 5 As shown, the outer walls of the connecting block 3 and the insert block 2 are both provided with an embedding groove 7, a strap 8 for being inserted into the embedding groove 7 is provided in the embedding groove 7 of one insert block 2, and a fixing structure for being connected to the strap 8 is provided on one connecting block 3.

[0023] Specifically, the fixing structure includes a capping 9 arranged on the top of a connecting block 3, and a fixing cavity 10 for one end of the strap 8 to be inserted into is formed between the capping 9 and the inner wall of the embedding groove 7 of the connecting block 3. A plurality of fixing teeth 11 are arranged in an array on the bottom wall of the fixing cavity 10, and a fixing groove 12 is formed between adjacent fixing teeth 11. A plurality of fixing teeth 2 13 for inserting into the fixing groove 12 are arranged at one end of the strap 8, and a guiding inclined surface 14 is provided at one end of the fixing tooth 2 13, and a limiting plane 15 is provided at the other end.

[0024] After the two tube bodies 1 are butted against each other, it is only necessary to rotate the binding belt 8 in a circular direction so that the binding belt 8 is sequentially inserted into the embedding grooves 7 on the surfaces of the connecting block 3 and the embedding block 2 until it is inserted into the fixing cavity 10 and then pulled out of the fixing cavity 10, so that the binding belt 8 can bind the butt joint of the two tube bodies 1 tightly, thereby greatly improving the connection strength of the two tube bodies 1.

[0025] In addition, since one end of the strap 8 is provided with a plurality of fixing teeth 13 for inserting into the fixing grooves 12, one end of the fixing teeth 13 is provided with a guiding slope 14, and the other end is provided with a limiting plane 15, when the strap 8 enters the fixing cavity 10, the fixing teeth 13 can easily enter the fixing cavity 10 and gradually abut against the fixing teeth 1 11 and insert into a plurality of fixing grooves 12 through the guiding effect of the guiding slope 14, so that the installation operation of the strap 8 is convenient, and the limiting effect of the limiting plane 15 makes it impossible for the strap 8 to be pulled out from the fixing cavity 10 in the reverse direction, thereby improving the connection stability of the strap 8.
