In order to solve the technical problem, the utility model provides a following technical scheme: including MPP cable protection pipe, MPP cable protection pipe grafting end is provided with the screw rod that can rotate, be provided with the stopper that can lock the screw rod on the screw rod, MPP cable protection pipe locking end is provided with the thread groove.

Preferably, the MPP cable protection pipe plug end is provided with the turning block, the stopper sets up on the turning block.

Preferably, the MPP cable protection pipe plug end is provided with an elastic block, and the elastic block wraps the rotating block and the limiting block.

Preferably, a plurality of inserting holes are formed in the corresponding positions of the surfaces of the elastic block and the limiting block in a circumferential array mode.

Preferably, the MPP cable protection pipe locking end is provided with the protection storehouse, the protection storehouse surface is provided with the seal groove.

Preferably, a bolt is arranged on the surface of the sealing groove corresponding to the insertion hole.

Preferably, the elastic block is made of rubber, and the outer diameter of the elastic block is the same as the inner diameter of the sealing groove.

Preferably, the plug pin and the plug hole are matched and plugged with each other.

Compared with the prior art, the beneficial effects of the utility model are that:

wholly when splicing, insert the screw rod of MPP cable protection pipe plug-in connection end in the seal groove of another MPP cable protection pipe locking end, can contact each other and produce the extrusion with the thread groove along with continuous inserting screw rod, under the combined action of extrusion and screw thread, the screw rod begins to rotate, and with the continuous screw thread combination of thread groove, the elastic block can contact each other with the surface of seal groove, because the elastic block is made by rubber, and its outside diameter is the same with seal groove internal diameter, rubber has fine leakproofness, and have certain elasticity, with the help of external application force and its elasticity itself, let it insert in the seal groove, and outside diameter between them is the same with the internal diameter, the seal groove can produce great extrusion to the elastic block like this, finally form seal structure under the effect of extrusion, insert the bolt in the spliced eye on stopper surface through the external force, thereby spacing the screw rod, and lock whole device, and can realize holistic dismantlement through extracting bolt reverse operation, whole device need not to realize tradition connection and dismantlement with the help of a large amount of external tools when connecting, its safety of hot melt welding operation that compares is higher, and can's under the effect of protection storehouse directly, can's on a large scale, the MPP is applicable to the cable protection pipe on a large scale more.

Detailed Description

In order to facilitate the problem of solution, the embodiment of the utility model provides a need not external adapter sleeve directly to splice formula MPP cable protection pipe. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, this embodiment provides a direct splicing type MPP cable protection tube without an external connection sleeve, including an MPP cable protection tube 1, a plugging end of the MPP cable protection tube 1 is provided with a rotatable screw 7, a limiting block 9 capable of locking the screw 7 is arranged on the screw 7, a locking end of the MPP cable protection tube 1 is provided with a thread groove 10, a plugging end of the MPP cable protection tube 1 is provided with a rotating block 8, the limiting block 9 is arranged on the rotating block 8, a plurality of plugging holes 6 are arranged in a circumferential array at positions corresponding to the surfaces of the elastic block 5 and the limiting block 9, a plug pin 4 is arranged at a position corresponding to the plugging hole 6 on the surface of the sealing groove 3, and the plug pin 4 and the plugging hole 6 are mutually matched and plugged.

In this embodiment, wholly when splicing, insert the screw rod 7 of 1 grafting end of MPP cable protection pipe in the seal groove 3 of 1 locking end of another MPP cable protection pipe, along with continuous insert screw rod 7 can with thread groove 10 contact each other and produce the extrusion, under the combined action of extrusion and screw thread, screw rod 7 begins to rotate, and combine with the continuous screw thread of thread groove 10, insert bolt 4 in the spliced eye 6 on stopper 9 surface through external force, thereby it is spacing to carry out screw rod 7, and then lock whole device, and can realize holistic dismantlement through extracting 4 reverse operations of bolt.

Referring to fig. 1-3, the embodiment provides a direct splicing type MPP cable protection tube without an external connection sleeve, an elastic block 5 is disposed at a splicing end of the MPP cable protection tube 1, the elastic block 5 wraps a rotating block 8 and a limiting block 9, a protection bin 2 is disposed at a locking end of the MPP cable protection tube 1, a sealing groove 3 is disposed on a surface of the protection bin 2, and the elastic block 5 is made of rubber and has an outer diameter the same as an inner diameter of the sealing groove 3.
