Description

Technical Field

[0001] This utility model relates to the field of power pipelines, and in particular to a power pipeline connection device. Background Technology

[0002] Power pipelines are important infrastructure used for cable laying and protection in power engineering. They are mainly divided into types such as power ducts and buried power pipes, and are characterized by high strength and low frictional resistance.

[0003] By seamlessly connecting multiple sections of power pipelines to form a continuous and closed pipeline system, a channel is provided for cable laying, thereby ensuring electrical continuity and safety. When connecting existing power pipelines, a special hot melt machine is used to heat the pipe ends to a hot melt state, and then they are quickly connected and pressure is applied. After cooling, a strong and integrated connection is formed.

[0004] In summary, the existing technology of connecting pipes by heat fusion makes the power pipes almost identical to the base material. This makes the permanent integrated structure formed by heat fusion more difficult to maintain. When a section of the pipe is damaged, the entire section must be cut off and then the new pipe section must be re-fused to the original pipe using a heat fusion machine. This results in problems with low flexibility and maintainability. Utility Model Content

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides an electrical conduit connection device, including a conduit assembly 1, and a fastening assembly 2 is sleeved on the outside of the conduit assembly 1. Pipe assembly 1 includes a first pipe 11, one end of which is fitted with a second pipe 12. A groove 110 is provided at the connection between the first pipe 11 and the second pipe 12. Multiple balls 13 are provided at one end of the second pipe 12, which are used to fix the second pipe 12 to one end of the first pipe 11. Fastening assembly 2 includes a disassembly ring 21 and a fixing ring 23. A pressure block 211 protrudes from the center of the disassembly ring 21. A movable groove 210 is provided at one end of the disassembly ring 210, and a return spring 22 is provided inside the movable groove 210. An inclined groove 212 is provided at the other end of the disassembly ring 21. After one end of the second pipe 12 is engaged with the balls 13 inside the blind hole 121 in the groove 110, a preliminary connection is made between the first pipe 11 and the second pipe 12. Due to the return spring 22 inside the movable groove 210, the connection is maintained. Under its own elasticity, the pressure block 211 set in the middle of the disassembly ring 21 is always pressed against the top of the blind hole 121, limiting the position of the ball 13. Under the snapping action of the ball 13, the first pipe 11 and the second pipe 12 can always be connected. The inclined groove 212 is used to connect the blind hole 121 and the inclined groove 212 when it is necessary to disconnect the connection between the first pipe 11 and the second pipe 12. By sliding the disassembly ring 21 sleeved on the outside of the second pipe 12, the ball 13 is connected to the blind hole 121. At this time, there is no structure to limit the top of the ball 13. At the same time, the first pipe 11 and the second pipe 12 are pulled to both ends. One end surface of the first pipe 11 can apply a pushing force to the ball 13, causing the ball 13 to disengage from the inside of the slot 110, thereby disconnecting the connection between the first pipe 11 and the second pipe 12.

[0022] Multiple blind holes 121 are formed around the second pipe 12. Ball bearings 13 are movably connected inside the blind holes 121. The walls of the blind holes 121 are tapered surfaces that gradually expand from the center outwards to both ends. A sealing ring 112 extends outwards from the center of one end of the second pipe 12. A limiting groove 111 protrudes from the circumferential side of the first pipe 11. One end of the second pipe 12 is engaged inside the limiting groove 111, and the sealing ring 112 fits against the circumferential side of the first pipe 11. A baffle 120 protrudes from the circumferential side of the second pipe 12 and is engaged at one end of the movable groove 210. A reset spring... Spring 22 surrounds the cavity formed by movable groove 210 and the surface of second pipe 12. Blind hole 121 can limit the position of ball 13. At the same time, the diameter of ball 13 is greater than the depth of blind hole 121. Ball 13 can connect the first pipe 11 and the second pipe 12 by changing the convex state at both ends of blind hole 121. Sealing ring 112 is made of rubber material and can seal the gap between the first pipe 11 and the second pipe 12. Under the limiting effect of fixed ring 23 and the surface of first pipe 11, the sealing performance is better.

[0023] The disassembly ring 21 is sleeved on one end of the second pipe 12 by the elastic action of the return spring 22, and the pressure block 211 abuts against the top of the blind hole 121. The ball 13 is locked inside the second pipe 12 through the blind hole 121. The diameter of the ball 13 is larger than the depth of the blind hole 121. After part of the spherical surface of the ball 13 protrudes from the blind hole 121, it is locked inside the slot 110. There is a gap between the inclined groove 212 and the circumferential side of the second pipe 12. An arc-shaped slot 213 is provided at one end of the inclined groove 212. Under the support of the return spring 22 on the baffle 120 inside the movable groove 210, the disassembly ring 21 is stabilized outside the connection part of the first pipe 11 and the second pipe 12, thereby achieving the function of fastening the connection part of the first pipe 11 and the second pipe 12.

[0024] The surface of the fixing ring 23 is symmetrically provided with locking protrusions 230, which are engaged inside the arc-shaped locking groove 213. The contours of the locking protrusions 230 and the arc-shaped locking groove 213 are complementary. The locking protrusions 230 can be engaged into the interior of the arc-shaped locking groove 213 along a non-axial path. A pressure plate 231 extends from one end of the fixing ring 23 near the second pipe 12. The sealing ring 112 is engaged in the gap formed between the bottom of the pressure plate 231 and the surface of the first pipe 11. Since the disassembly ring 21 needs to be fixed to prevent the ball 13 from disengaging from the interior of the locking groove 110 when the disassembly ring 21 moves due to external force, the connection between the first pipe 11 and the second pipe 12 is released. Rotating the fixing ring 23 allows the locking protrusions 230 to be engaged into the interior of the arc-shaped locking groove 213 along the rotation path, thereby fixing the position of the disassembly ring 21.

[0025] Working principle: When connecting the first pipe 11 and the second pipe 12, the end of the first pipe 11 with the groove 110 is first aligned with the end of the second pipe 12 with the ball bearing 13. The ball bearing 13 engages to keep the first pipe 11 and the second pipe 12 connected. Because the diameter of the ball bearing 13 is larger than the depth of the blind hole 121, the bottom of the blind hole 121 limits the position of the ball bearing 13. The ball bearing 13 can connect the first pipe 11 and the second pipe 12 by changing the protrusion at both ends of the blind hole 121. The sealing ring 112, made of rubber, can seal the gap between the first pipe 11 and the second pipe 12. With the limiting effect of the fixing ring 23 and the surface of the first pipe 11, the sealing performance is better. When it is necessary to disconnect the connection between the first pipe 11 and the second pipe 12, the first pipe 11 and the second pipe 12 are pulled to both ends. One end of the first pipe 11 can apply a pushing force to the ball 13, causing the ball 13 to disengage from the inside of the groove 110, thereby disconnecting the connection between the first pipe 11 and the second pipe 12.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
