Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, and in particular to an MPP power pipe connector. Background Technology
[0002] MPP power conduit, short for modified polypropylene power conduit, is a type of pipe specifically designed for power engineering. MPP power conduit boasts high compressive strength, capable of withstanding soil and ground pressure, as well as vehicle loads, and is resistant to deformation, ensuring the safe operation of power cables. For example, during road construction, even when large construction machinery operates on the surface, the buried MPP power conduit remains intact.
[0003] Connecting MPP power conduits to connectors may require complex methods, such as traditional heat fusion or threaded connections. Heat fusion requires specialized equipment and time-consuming processes involving cooling and solidification. Threaded connections require manual tightening, which is difficult and slow for large-diameter conduits, leading to inefficient installation. Separating the conduit may require damaging the connector or conduit, wasting materials and increasing installation time and costs. After connecting two MPP power conduits, even slight tension, thrust, or vibration can cause relative displacement between the connector and the conduit, leading to loosening or even separation of the two conduits. This affects the normal operation of the power system. Over time, the connector may not be able to withstand the weight and pressure of the conduit, causing deformation and loosening of the connection. This can affect the insulation performance of the cables inside the conduit, increasing the risk of power transmission failures and compromising the stability and integrity of the entire system. Utility Model Content
[0004] The main purpose of this utility model is to provide an MPP power pipe connector that can effectively solve the problems of low installation efficiency, which require damage to the connector or power pipe to separate them. This not only wastes materials, but also increases installation time and cost, and affects the insulation performance of the cables inside the pipe, increases the risk of power transmission failure, and damages the stability and integrity of the entire system.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an MPP power pipe connector, comprising a front hoop, two first inclined blocks fixedly connected to the upper and lower sides of the front hoop, a rear hoop provided on the rear side of the front hoop, and two second inclined blocks fixedly connected to the upper and lower sides of the rear hoop, the front hoop and the rear hoop being correspondingly arranged, a guide rail groove being provided inside each of the first and second inclined blocks, a fixing cover being provided on the outer side of each of the first and second inclined blocks, and two sliders fixedly connected to the front and rear sides of the interior of each fixing cover, with each pair of sliders disposed inside the guide rail groove.
[0006] Furthermore, a first sealing ring is fixedly connected to both the left and right ends of the front hoop and the rear hoop, and a second sealing ring is fixedly connected to the inside of both the front hoop and the rear hoop.
[0007] Furthermore, the right side walls of the two first inclined blocks and the second inclined blocks are fixedly connected to connecting blocks, and the right side walls of the four connecting blocks are fixedly connected to locking blocks.
[0008] Furthermore, the right side walls of both fixed covers are fixedly connected to outer shells, and each outer shell is slidably connected to sliding rods on both the front and rear sides.
[0009] Furthermore, each of the slide bars has two first springs fixedly connected to its inner sidewall, and the other end of every four first springs is fixedly connected to an internal slot in the housing.
[0010] Furthermore, two placement slots are provided on the left side of the interior of both housings, and two second springs are fixedly connected inside each placement slot. A baffle is fixedly connected to the other side of each pair of second springs.
[0011] Furthermore, the outer side of each card block is correspondingly set with the inside of a placement slot, and the internal hole slot of each card block is correspondingly set with the bottom of the slide bar.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, through its front clamp, rear clamp, second inclined block, fixing cover, first sealing ring, and second sealing ring, solves the problem of low installation efficiency, which previously required damaging connectors or power pipes to separate them. This not only wastes materials but also increases installation time and cost. The fixing cover is installed on the outside of the first and second inclined blocks, and the sliders on the front and rear sides of the fixing cover are embedded in guide rail grooves. By pushing the fixing cover along the guide rail grooves, the sliders slide within the grooves, causing the fixing cover to gradually approach and press against the first and second inclined blocks. As the fixing cover moves, the first and second inclined blocks are compressed, and the front and rear clamps gradually approach and clamp the MPP power pipe, thus fixing the pipe. This significantly shortens the overall installation time, reduces material waste and maintenance workload, and lowers maintenance costs.
[0014] 2. By incorporating a locking block, sliding rod, first spring, placement groove, second spring, and baffle, the system effectively addresses issues that could compromise the insulation performance of cables inside the conduit, increase the risk of power transmission failures, and disrupt the stability and integrity of the entire system. The locking block pushes the sliding rod within the casing, compressing the first spring. Once the first spring is breached, the right side wall of the locking block contacts the baffle, compressing and deforming the second spring. When the locking block fully enters the placement groove, the first spring immediately releases pressure, causing the sliding rod to reset. Upon reset, the sliding rod inserts into the locking block's slot, firmly fixing the locking block within the casing and ensuring that the front and rear clamps tightly hold the MPP power pipe, guaranteeing a stable connection. This effectively reduces maintenance costs and workload, avoids decreased connection reliability due to wear of connectors, and promotes the long-term stable operation of the power pipe system.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] like Figure 1 - Figure 9 As shown: An MPP power pipe connector includes a front clamp 1, with two first inclined blocks 2 fixedly connected to both the upper and lower sides of the front clamp 1. A rear clamp 3 is provided on the rear side of the front clamp 1, with two second inclined blocks 4 fixedly connected to both the upper and lower sides of the rear clamp 3. The front clamp 1 and the rear clamp 3 are arranged correspondingly. The first inclined blocks 2 on the outer side of the front clamp 1 and the second inclined blocks 4 on the outer side of the rear clamp 3 form a positioning frame to place the ports of the two MPP power pipes to be connected on the outside.
[0030] Each of the first inclined blocks 2 and the second inclined block 4 has a guide groove 5 inside, which serves as a guide for the sliding of the externally fixed device. Each of the first inclined blocks 2 and the second inclined block 4 has a fixing cover 6 on its outer side. Two sliders 7 are fixedly connected to the front and rear sides of the interior of each fixing cover 6. Each pair of sliders 7 is located inside the guide groove 5. By installing the fixing cover 6 on the outside of the first inclined blocks 2 and the second inclined blocks 4, the sliders 7 on the front and rear sides of the fixing cover 6 are embedded in the guide groove 5. By pushing the fixing cover 6 along the guide groove 5, the sliders 7 slide within the guide groove 5, causing the fixing cover 6 to gradually approach and press against the first inclined blocks 2 and the second inclined blocks 4. As the fixing cover 6 moves, the first inclined blocks 2 and the second inclined blocks 4 are compressed, and the front clamp 1 and the rear clamp 3 gradually approach and clamp the MPP power pipe, thus fixing the pipe.
[0031] Both ends of the front clamp 1 and the rear clamp 3 are fixedly connected with first sealing rings 8, and both the front clamp 1 and the rear clamp 3 are fixedly connected with second sealing rings 9. Through the first sealing rings 8 at both ends of the front clamp 1 and the rear clamp 3, during the clamping process of the pipe, they are compressed and deformed, tightly fitting against the outer surface of the MPP power pipe and the connection gap between the front and rear clamps, forming the first line of defense to prevent external water, dust, and other impurities from entering the connection area from both ends of the clamps. Simultaneously, the second sealing rings 9 inside the front clamp 1 and the rear clamp 3 also come into close contact with the inner wall of the pipe due to the clamping force, forming a second line of defense to further prevent impurities from entering the pipe, ensuring the sealing and insulation of the power pipe connection area, and guaranteeing the safety of power transmission.
[0032] Connecting blocks 10 are fixedly connected to the right side walls of the two first inclined blocks 2 and the second inclined blocks 4. Locking blocks 11 are fixedly connected to the right side walls of the four connecting blocks 10. Outer shells 12 are fixedly connected to the right side walls of the two fixed covers 6. The connecting blocks 10 on the right side walls of the first inclined blocks 2 and the second inclined blocks 4 are connected to the locking blocks 11, and the locking blocks 11 are connected to the outer shells 12 on the right side walls of the fixed covers 6 to strengthen the fixation of the front hoop 1 and the rear hoop 3.
[0033] Each outer shell 12 has a sliding rod 13 slidably connected to its front and rear sides. Each sliding rod 13 has two first springs 14 fixedly connected to its inner side wall. The other end of every four first springs 14 is fixedly connected to the internal slot of the outer shell 12. When the operator presses the sliding rod 13, the sliding rod 13 will slide inside the outer shell 12 to squeeze the first springs 14. When the sliding rod 13 is released, the first springs 14 release the pressure and drive the sliding rod 13 to spring back to its original position.
[0034] Two placement slots 15 are formed on the left side of the interior of each of the two outer shells 12. Two second springs 16 are fixedly connected inside each placement slot 15. A baffle 17 is fixedly connected to the other side of each pair of second springs 16. The outer side of each locking block 11 corresponds to the interior of one placement slot 15. The internal hole of each locking block 11 corresponds to the bottom of the slide rod 13. When the locking block 11 is inserted into the placement slot 15, the locking block 11 will first push the slide rod 13 to slide inside the outer shell 12 to compress the first When the first spring 14 is broken, the right side wall of the locking block 11 will contact the baffle 17, causing the baffle 17 to compress and deform the second spring 16. When the locking block 11 is fully inserted into the placement groove 15, the first spring 14 will immediately release pressure to drive the slide rod 13 to reset. When the slide rod 13 is reset, it will be inserted into the slot of the locking block 11, so that the locking block 11 is firmly fixed in the inside of the outer shell 12, and ensure that the front clamp 1 and the rear clamp 3 tightly hold the MPP power pipe to ensure a stable connection.
[0035] It should be noted that this utility model is an MPP power pipe connector. Firstly, when connecting two MPP power pipes, the front clamp 1 and the rear clamp 3 are placed on either side of the pipe to be connected. The first inclined blocks 2 on the upper and lower sides of the front clamp 1 and the second inclined blocks 4 on the upper and lower sides of the rear clamp 3 are correspondingly distributed, forming a preliminary positioning frame. At this time, the guide grooves 5 inside the first inclined blocks 2 and the second inclined blocks 4 provide tracks for the subsequent installation and movement of components.
[0036] The fixing cover 6 is installed on the outside of the first inclined block 2 and the second inclined block 4. The sliders 7 on the front and rear sides of the fixing cover 6 are embedded in the guide rail grooves 5. By pushing the fixing cover 6 along the guide rail grooves 5, the sliding of the sliders 7 within the guide rail grooves 5 causes the fixing cover 6 to gradually approach and press against the first inclined block 2 and the second inclined block 4. As the fixing cover 6 moves, the first inclined block 2 and the second inclined block 4 are compressed, and the front clamp 1 and the rear clamp 3 gradually approach and clamp the MPP power pipe, thus fixing the pipe.
[0037] When the fixed cover 6 moves to the predetermined position, the locking block 11 on the connecting block 10 aligns with the placement slot 15 inside the housing 12. During the insertion of the locking block 11 into the placement slot 15, it first pushes the slide rod 13 to slide inside the housing 12 to compress the first spring 14. After breaking through the first spring 14, the right side wall of the locking block 11 will contact the baffle 17, causing the second spring 16 to compress and deform. When the locking block 11 is fully inserted into the placement slot 15, the first spring 14 will immediately release pressure to drive the slide rod 13 to reset. When the slide rod 13 resets, it will insert into the slot of the locking block 11, so that the locking block 11 is firmly fixed inside the housing 12, and ensures that the front clamp 1 and the rear clamp 3 tightly hold the MPP power pipe, ensuring a stable connection.
[0038] When disassembly is required, the operator presses the slide bar 13, causing it to slide inside the housing 12 and compress the first spring 14. At this time, the bottom of the slide bar 13 slides out of the slot of the locking block 11, pushing the fixing cover 6 to the right. This allows the locking block 11 to slide out of the placement slot 15, and the slider 7 inside the fixing cover 6 to slide out of the guide rail slot 5. When the slide bar 13 is released, it will spring back to its original position via the first spring 14. Additionally, the second spring 16 inside the placement slot 15 will cause the baffle 17 to spring back, sealing the interior of the placement slot 15 to prevent dust and impurities from entering the depths of the placement slot 15.
