Description

Technical Field

[0001] The utility model relates to the field of electric power pipes, in particular to an MPP pipe. Background Art

[0002] At present, many buried and installed power pipes mostly use MPP pipes. When burying MPP pipes, it is often involved to connect the MPP pipes to assemble the required length of the pipe. Among them, the current connection of MPP pipes is mostly done by hot-melt connection. Before connection, you need to prepare a hot-melt welding machine, a cutting machine, and a cleaning cloth; then clamp the ends of the two MPP pipes to be connected together into the hot-melt welding machine; then place the cutting machine on the hot-melt welding machine, and use the cutting machine to cut and trim the ports of the two MPP pipes; then use the hot-melt welding machine to try to connect the ports of the two MPP pipes together to check whether the cutting and trimming treatment is in place; if not, continue the cutting and trimming treatment until it is in place; if in place , wipe the ports of the two MPP pipes with a cleaning cloth; then place the hot plate of the hot melt welding machine between the ports of the two MPP pipes, and make the ports of the two MPP pipes stick to the hot plate, so as to use the hot plate to heat the ports of the two MPP pipes to a hot melt state (the heating temperature is generally controlled at 200-220℃ to avoid excessive deformation and ensure accurate and stable docking); then use the hot melt welding machine to make the ports of the two MPP pipes close together; then you need to wait for a long time so that the docking point can be fully cooled and solidified, so as to achieve effective docking of the MPP pipes. The process of docking MPP pipes in this way is very cumbersome, which not only easily leads to a high labor intensity for workers, but also easily leads to low docking efficiency, which easily leads to low construction efficiency of related projects. Therefore, it is very necessary to redesign the structure of the MPP pipe. Utility Model Content

[0007] Preferably, a locking screw capable of being locked on the embedded sleeve is passed through the positioning sleeve and / or a locking screw capable of being locked on the positioning sleeve is arranged on the embedded sleeve.

[0008] Preferably, a first limiting convex ring is provided on the outer circumferential surface of one end of the tube body, and a first positioning convex ring is provided on the inner wall of the positioning sleeve, so that the first positioning convex ring can be abutted against the end surface of the first limiting convex ring close to the middle of the tube body.

[0009] Preferably, a second limiting convex ring is provided on the outer circumferential surface of the other end of the tube body, and a second positioning convex ring is provided on the inner wall of the embedded sleeve, so that the second positioning convex ring can be abutted against the end surface of the second limiting convex ring close to the middle of the tube body.

[0010] Preferably, at least one buckle groove is formed on the inner wall of the positioning block, and the buckle block is provided with buckle convex parts whose number is equal to the buckle grooves and whose positions correspond one to one.

[0011] Preferably, a first guiding slope is provided on a corner of the positioning block, and a second guiding slope is provided on a corner of the buckle block.

[0025] like Figures 1 to 4 As shown, the utility model is a method for fixing an MPP pipe, comprising a pipe body 1, a positioning sleeve 2, and an embedding sleeve 3, wherein the positioning sleeve 2 can be rotatably mounted on one end of the pipe body 1, and the embedding sleeve 3 can be rotatably mounted on the other end of the pipe body 1, and the inner wall of the positioning sleeve 2 is provided with a plurality of positioning blocks 21 arranged around its axial center line, and the outer wall of the embedding sleeve 3 is provided with a plurality of snap blocks 31 which can be embedded in the positioning sleeve 2 and can rotate with the embedding sleeve 3 and are respectively snapped on the inner walls of each positioning block 21.

[0026] In the MPP pipe that is easy to fix, a rotatable positioning sleeve 2 and an embedded sleeve 3 are respectively provided at both ends of the pipe body 1, and a plurality of positioning blocks 21 arranged around its axial center line are provided on the inner wall of the positioning sleeve 2, and a plurality of snap blocks 31 that can be embedded in the positioning sleeve 2 and can rotate with the embedded sleeve 3 and snap onto the inner wall of the positioning block 21 are also provided on the outer wall of the embedded sleeve 3. In this way, when two MPP pipes need to be butt-jointed, by embedding the embedded sleeve 3 on one MPP pipe on the positioning sleeve 2, and then rotating the embedded sleeve 3 or the positioning sleeve 2, each snap block 31 can be snapped onto the inner wall of each positioning block 21. This can help to quickly and stably connect the two MPP pipes together, and can avoid relative movement of the positioning sleeve and the embedded sleeve in the axial and radial directions, which can help to ensure that the connection is very stable and reliable. The easy fixation of the MPP pipe can greatly simplify the connection process of the MPP pipe, which can not only help to greatly reduce the labor intensity of workers, but also help to greatly improve the efficiency of the connection, thereby helping to improve the construction efficiency of related projects.

[0027] like Fig. 9 and Fig.10 As shown, when docking the MPP pipe 10 of the utility model, first make the ports of the two MPP pipes 10 close together, and clamp the sealing rubber ring 20 between the ports of the two MPP pipes 10; then make the buckle blocks 31 on the embedded sleeve 3 embedded in the positioning sleeve 2; then make the positioning sleeve 2 and the embedded sleeve 3 rotate relative to each other, so that each buckle block 31 is buckled on the inner wall of each positioning block 21; this can dock the two MPP pipes together. This docking of MPP pipes is very simple and convenient, which can not only greatly reduce the labor intensity of workers, but also greatly improve the efficiency of docking, thereby improving the construction efficiency of related projects.

[0028] like Figures 5 to 8 As shown, at least one first toggle protrusion 22 is provided on the outer wall of the positioning ferrule 2, and at least one second toggle protrusion 32 is provided on the outer wall of the embedded sleeve 3. The first toggle protrusion 22 and the second toggle protrusion 32 can be operated by hand, which can facilitate the operation of rotating the positioning ferrule 2 and the embedded sleeve 3 when docking the MPP pipe to avoid slipping, thereby further improving the convenience of docking.

[0029] like Figure 2 and Figure 6As shown, the positioning sleeve 2 is penetrated with a locking screw 4 that can be locked on the embedded sleeve 3 and / or the embedded sleeve 3 is provided with a locking screw 4 that can be locked on the positioning sleeve 2. The locking screw 4 can lock the positioning sleeve 2 and the embedded sleeve 3 together after the positioning sleeves 2 and the embedded sleeves 3 of the two MPP tubes are nested and the snap block 31 snaps the positioning block 21, which helps to further improve the stability and reliability of docking, thereby helping to further improve the reliability and applicability of the MPP tube fixing. Only one or two locking screws 4 are needed here to achieve effective locking, so the setting of the locking screw 4 will not make the docking operation too cumbersome, which can still ensure that the docking of the MPP tube is very convenient.

[0030] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a first limiting convex ring 11 is provided on the outer circumferential surface of one end of the pipe body 1, and a first positioning convex ring 23 is provided on the inner wall of the positioning ferrule 2, so that the first positioning convex ring 23 can be abutted against the end surface of the first limiting convex ring 11 close to the middle of the pipe body 1. In this way, not only can the rotation requirements of the positioning ferrule 2 be met very well, but also the positioning ferrule 2 can be accurately and stably positioned, thereby improving the stability and reliability of docking.

[0031] like Figure 5 and Figure 6 As shown, the first positioning convex ring 23 and each positioning block 21 are respectively located on the two port edges of the positioning ferrule 2, and a clearance ring groove 210 for the buckle block 31 to enter and exit is reserved between the positioning block 21 and the first positioning convex ring 23. This can make the positioning ferrule 2 have a very compact and reliable structure, which can not only reduce the use of raw materials, but also ensure that the docking is very stable and reliable.

[0032] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, a second limiting protrusion 12 is provided on the outer circumferential surface of the other end of the pipe body 1, and a second positioning protrusion 33 is provided on the inner wall of the embedded sleeve 3, so that the second positioning protrusion 33 can be abutted against the end surface of the second limiting protrusion 12 close to the middle of the pipe body 1. In this way, not only can the rotation requirements of the embedded sleeve 3 be met very well, but also the embedded sleeve 3 can be accurately and stably positioned, thereby improving the stability and reliability of docking.

[0033] like Figure 7 and Figure 8 As shown, the second positioning protruding ring 33 and each buckle block 31 are respectively located on the inner and outer circumferential edges of both ends of the embedded sleeve 3. This can make the embedded sleeve 3 have a very compact and reliable structure, which can not only reduce the use of raw materials, but also ensure that the docking is very stable and reliable.

[0034] like Figure 5 and Figure 7 As shown, at least one buckle groove 211 is formed on the inner wall of the positioning block 21, and the buckle block 31 is provided with buckle convex portions 311, which are equal in number and position to the buckle grooves 211. This enables the corresponding positioning block 21 and the buckle block 31 to achieve very stable and reliable buckling during docking, thereby ensuring very stable and reliable docking.

[0035] like Figure 7 As shown, the side wall of the buckle convex part 311 is a circular arc guide surface 3111, and the notch edge of the buckle groove 211 matches the circular arc guide surface 3111. This not only facilitates the buckle convex part 311 to be buckled, but also facilitates disassembly, thereby better meeting the needs of actual use, which helps to further improve the applicability of the MPP tube that is easy to fix.

[0036] like Figure 5 and Figure 7 As shown, the corners of the positioning block 21 are provided with first guiding slopes 212, and the corners of the buckle block 31 are provided with second guiding slopes 312. The first guiding slopes 212 and the second guiding slopes 312 can play a guiding role when the buckle block 31 is embedded, so that the buckle block 31 can be buckled more smoothly and accurately, thereby helping to further improve the convenience of assembly.

[0037] like Figures 1 to 8 As shown, the positioning sleeve 2 and each positioning block 21 are an integrated stainless steel structure, and the embedded sleeve 3 and each buckle block 31 are an integrated stainless steel structure. This can not only improve the structural strength, but also improve the durability, thereby helping to further improve the reliability and service life of the MPP pipe fixing device.

[0038] like Figures 1 to 4 As shown, the end surfaces of both ends of the pipe body 1 are respectively provided with positioning ring grooves 13 surrounding the pipe opening. Fig.10 As shown, the positioning ring groove 13 can be used to accurately position the sealing rubber ring 20, so as to ensure that the sealing effect after docking is very stable and reliable, thereby helping to further improve the reliability and applicability of the MPP pipe fixing device.

[0039] like Figures 1 to 4 , Fig.10 As shown, in order to make the positioning ring groove 13 have a sufficient groove width, the positioning ring groove 13 can be extended to the first limiting convex ring 11 or the second limiting convex ring 12, which can help increase the contact area of ​​the sealing rubber ring 20, thereby further improving the sealing performance.
