Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, specifically to an MPP pipe structure that facilitates connection. Background Technology
[0002] MPP pipes are mainly made of modified polypropylene material, which has excellent properties such as high temperature resistance, external pressure resistance, aging resistance, chemical corrosion resistance and low water absorption, making them suitable for power engineering and other special construction environments.
[0003] Currently, most MPP pipe connections are made using heat fusion, which results in a slow connection speed. Additionally, heat fusion equipment is not easy to move, leading to poor connection efficiency. Furthermore, the sealing ring may detach from the pipe internally, resulting in poor sealing performance and leakage, ultimately causing the internal components to lose their protection. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an MPP pipe structure that is easy to connect, with advantages such as easy connection and high fit between the sealing ring and the pipe, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: an MPP pipe structure that facilitates connection, including a connecting pipe, a fixing plate fixedly installed on the outer wall of the connecting pipe, an MMP pipe body provided on the inner wall of the fixing plate, a spring provided on the inner wall of the connecting pipe, a push cylinder slidably connected to the inner wall of the connecting pipe, a first sealing ring fixedly installed on the inner wall of the connecting pipe, a second sealing ring fixedly installed on the side of the push cylinder away from the spring, an extension ring fixedly installed on the outer wall of the MMP pipe body, a locking plate slidably connected to the inner wall of the fixing plate, a limit groove formed on the inner wall of the connecting pipe, a limit block fixedly installed on the outer wall of the push cylinder, a double-ended screw rotatably connected to the inner wall of the fixing plate, a limit rod fixedly installed on the inner wall of the fixing plate, a connecting plate fixedly installed on the top of the locking plate, a sliding plate fixedly installed on the top of the connecting plate, a rotating head fixedly installed on the outer wall of the double-ended screw, and a movable groove formed on the outer wall of the fixing plate.
[0006] As a preferred technical solution of this utility model: there are two limiting rods and two connecting plates, and the two limiting rods and the two connecting plates are symmetrically arranged, and the two limiting rods pass through the two connecting plates.
[0007] As a preferred technical solution of this utility model: the double-ended lead screw passes through the sliding plate, and the double-ended lead screw and the sliding plate are connected by threads.
[0008] As a preferred technical solution of this utility model: the number of the locking plate, sliding plate, connecting plate and limiting rod is two, and the two locking plates, sliding plates, connecting plates and limiting rods are symmetrically arranged, and the inner wall of the two locking plates is adapted to the outer wall diameter of the MMP tube body.
[0009] As a preferred technical solution of this utility model: the limiting block is located on the inner wall of the limiting groove, and the limiting block is in contact with the inner wall of the limiting groove.
[0010] As a preferred technical solution of this utility model: the size of the side of the pusher near the spring is adapted to the shape of the inner wall of the connecting tube, and the outer wall of the side of the pusher near the spring is in contact with the inner wall of the connecting tube.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This easy-to-connect MPP pipe structure, by rotating the rotating head, causes the double-ended screw to rotate, which in turn causes the double-ended screw to move the two connecting plates towards the center through the connection with the two connecting plates. In turn, the two connecting plates move the bottom locking plate towards the center through the two sliding plates, so that the two locking plates fit against the outer wall of the MMP pipe body. At this time, the two locking plates limit the extension ring to the inner wall of the connecting pipe, thereby fixing the extension ring to the inner wall of the connecting pipe and fixing the MMP pipe body.
[0013] 2. This easy-to-connect MPP pipe structure, by shifting the end of the MMP pipe body near the extension ring inward towards the interior of the fixing plate, allows the end of the MMP pipe body near the extension ring to overlap with the outer surface of the second sealing ring. At this time, the extension ring is further pushed towards the second sealing ring, causing the second sealing ring to move inward. This causes the second sealing ring to drive the push cylinder to move, compressing the spring. After the MMP pipe body is fixed, the spring's rebound pushes the push cylinder and the second sealing ring towards the extension ring, ensuring that the second sealing ring and the extension ring are always in contact. This prevents the sealing ring from failing to fully connect with the locking plate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 - Figure 5 An MPP pipe structure for easy connection includes a connecting pipe 1, a fixing plate 2 fixedly installed on the outer wall of the connecting pipe 1, an MMP pipe body 3 provided on the inner wall of the fixing plate 2, a spring 4 provided on the inner wall of the connecting pipe 1, a push cylinder 5 slidably connected to the inner wall of the connecting pipe 1, a first sealing ring 6 fixedly installed on the inner wall of the connecting pipe 1, a second sealing ring 7 fixedly installed on the side of the push cylinder 5 away from the spring 4, an extension ring 8 fixedly installed on the outer wall of the MMP pipe body 3, a locking plate 9 slidably connected to the inner wall of the fixing plate 2, a limit groove 10 formed on the inner wall of the connecting pipe 1, a limit block 11 fixedly installed on the outer wall of the push cylinder 5, a double-ended screw 12 rotatably connected to the inner wall of the fixing plate 2, a limit rod 13 fixedly installed on the inner wall of the fixing plate 2, a connecting plate 14 fixedly installed on the top of the locking plate 9, a sliding plate 15 fixedly installed on the top of the connecting plate 14, a rotating head 16 fixedly installed on the outer wall of the double-ended screw 12, and a movable groove 17 formed on the outer wall of the fixing plate 2.
[0022] In the above structure, the first sealing ring 6 seals the inner wall of the connecting pipe 1 near the push cylinder 5, thereby forming a sealed space between the connecting pipe 1 and the inner wall of the push cylinder 5, so that there is no leakage to the inner wall of the connecting pipe 1 near the push cylinder 5.
[0023] In a preferred embodiment, there are two limiting rods 13 and two connecting plates 14, and the two limiting rods 13 and the two connecting plates 14 are symmetrically arranged, with the two limiting rods 13 passing through the two connecting plates 14.
[0024] In the above structure, the two connecting plates 14 are penetrated by the two limiting rods 13, so that the two connecting plates 14 are limited by the two limiting rods 13. This allows the two connecting plates 14 to slide only on the outer wall of the two limiting rods 13 when they move, thus preventing the two connecting plates 14 from tilting when they move, and preventing the locking plate 9 from tilting when it moves.
[0025] In a preferred embodiment, the double-ended lead screw 12 passes through the sliding plate 15, and the double-ended lead screw 12 and the sliding plate 15 are threadedly connected.
[0026] In the above structure, by rotating the rotating head 16, the rotating head 16 drives the sliding plate 15 to move through the threaded connection with the sliding plate 15, which in turn drives the bottom connecting plate 14 to move, which in turn drives the bottom locking plate 9 to move.
[0027] In a preferred embodiment, there are two locking plates 9, sliding plates 15, connecting plates 14 and limiting rods 13, and the two locking plates 9, sliding plates 15, connecting plates 14 and limiting rods 13 are symmetrically arranged, and the inner wall of the two locking plates 9 is adapted to the outer wall diameter of the MMP tube body 3.
[0028] In the above structure, by moving the two locking plates 9 toward the center, the two locking plates 9 are made to fit against the outer wall of the MMP tube body 3. At this time, the two locking plates 9 limit the extension ring 8 to the inner wall of the connecting pipe 1, thereby fixing the extension ring 8 to the inner wall of the connecting pipe 1, and fixing the MMP tube body 3.
[0029] In a preferred embodiment, the limiting block 11 is located on the inner wall of the limiting groove 10, and the limiting block 11 is in contact with the inner wall of the limiting groove 10.
[0030] In the above structure, the limiting groove 10 and the limiting block 11 are fitted together, so that the limiting block 11 is limited when it moves, and thus the limiting block 11 will not tilt when it moves, so that the push cylinder 5 will not rotate when it moves.
[0031] In a preferred embodiment, the size of the push cylinder 5 near the spring 4 is adapted to the shape of the inner wall of the connecting pipe 1, and the outer wall of the push cylinder 5 near the spring 4 is in contact with the inner wall of the connecting pipe 1.
[0032] In the above structure, the push cylinder 5 and the inner wall of the spring 4 are attached together, so that the push cylinder 5 can only slide on the inner wall of the spring 4 when it moves, thus preventing the push cylinder 5 from tilting when it moves.
[0033] Working principle: When using the equipment, the end of the MMP tube body 3 near the extension ring 8 is moved inward towards the fixed plate 2, so that the end of the MMP tube body 3 near the extension ring 8 overlaps with the outer surface of the second sealing ring 7. At this time, the extension ring 8 is pushed towards the second sealing ring 7, so that the second sealing ring 7 moves inward, causing the second sealing ring 7 to drive the push cylinder 5 to move, causing the push cylinder 5 to compress the spring 4. When the extension ring 8 is pushed into the innermost part of the equipment and cannot move further, the rotating head 16 is rotated, so that the rotating head 16, through the threaded connection with the sliding plate 15, drives the sliding plate 15 to move, causing the sliding plate 15 to drive the bottom... The connecting plate 14 moves, which in turn causes the locking plate 9 at the bottom to move. As the two locking plates 9 move toward the center, they come into contact with the outer wall of the MMP tube body 3. At this time, the two locking plates 9 limit the extension ring 8 to the inner wall of the connecting tube 1, thus fixing the extension ring 8 to the inner wall of the connecting tube 1 and fixing the MMP tube body 3. After the MMP tube body 3 is fixed, the spring 4 pushes the push cylinder 5 and the second sealing ring 7 toward the extension ring 8, so that the second sealing ring 7 and the extension ring 8 are always in contact, thus preventing the sealing ring from failing to fully connect with the locking plate 9.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
