Description

Technical Field

[0001] This utility model relates to the field of cable protection pipes, and in particular to a power communication cable protection pipe. Background Technology

[0002] Power and communication cable protective sleeves are key components for protecting cables in power and communication engineering. When protecting long-distance cables such as those buried underground or strung across bridges, tubular protective sleeves are generally used to directly cover the cable surface, and the two sections of tubular protective sleeves are fixed together by glue, heat fusion or clips.

[0003] The reference patent title is: "An MPP Power Cable Protection Pipe for Easy Assembly" (Patent Publication No.: CN219535510U). The pipe body is divided into two halves, each half having a connecting groove on one side and a connecting block adapted to the groove on the other. A reinforcing structure is provided on the pipe body to strengthen the connection between the halves and increase the sealing at the connection point. The two pipe sections are positioned by connectors. Limiting blocks are fixed to the surface of the halves, and the connectors are configured as two semi-circular sleeves with limiting grooves. The limiting blocks and limiting grooves are inserted into each other, directly connecting the two pipe sections. This facilitates partial replacement of the cable or protective sleeve.

[0004] However, the following problems exist when implementing the above technical solutions: there are certain limitations to the connection between the two pipe sections in the above device, and pipe sections of a specific size need to be equipped during use or replacement; the positioning between the two pipe sections is mainly achieved by positioning the limiting blocks fixed on the surface of the half-pipe and the limiting groove inside the semi-circular sleeve. Limiting blocks must be used when connecting the two pipe sections, and it is difficult to ensure that the length of the cable to be protected matches the length of the pipe section during use. At the same time, the half-pipe is connected by grooves and blocks and has a reinforcing structure, making it difficult to connect directly with glue or hot melt. Therefore, a protective sleeve of a specific size may be required during the laying process.

[0005] Therefore, this utility model proposes a protective pipe for power communication cables. 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 5As shown in the figure, an embodiment of the present invention provides a power communication cable protection pipe, comprising: Two separate contact rings 21, both of which are in contact with the ends of the two protective tubes 1. Several elastic rods 22 are fixedly connected inside the contact rings 21, and the elastic rods 22 are evenly distributed on the surface of the contact rings 21. Two closed rings 23 are provided, each in contact with a contact ring 21, and the two closed rings 23 are symmetrically arranged relative to the center of the protective tube 1. An elastic ring 24 is slidably disposed inside each closed ring 23. The cross-section of the elastic ring 24 is trapezoidal, and the side of the elastic ring 24 contacts an elastic rod 22. An adjustment component for changing the size of the elastic ring 24 is provided between the closed rings 23 and the elastic rings 24. The relative positions of the two closed rings 23 are defined by a fixing component. In summary, the power communication cable protection pipe provided by this utility model embodiment includes a split contact ring 21 that contacts the protection pipe 1, and several elastic rods 22 are fixedly arranged inside the contact ring 21; a closing ring 23 is then provided, and an elastic ring 24 that contacts the elastic rods 22 is arranged inside the closing ring 23. Through the contact between the elastic ring 24 and the elastic rods 22, the elastic rods 22 can be squeezed, causing the elastic rods 22 to change position and increase the contact area with the protection pipe 1; the friction between the elastic rods 22 and the protection pipe 1 prevents the ends of the two sections of the protection pipe 1 from separating; the position of the protection pipe 1 is directly defined by squeezing and friction, without limiting the protection pipe 1 to a specific position for connection; therefore, the protection pipe 1 does not need to be equipped with a specific size when in use, and the protection pipe 1 can be arbitrarily cut according to the use requirements when assembling the cable, and then the contact ring 21 and the closing ring 23 are assembled according to the requirements to connect the next section of the protection pipe 1, thus having a wider range of applications; In some specific implementations, the adjusting assembly includes two support blocks 31 slidably disposed inside the elastic ring 24, and a support rod 32 slidably connected inside the closed ring 23. The support rod 32 is slidably connected to the support ring, and the two support blocks 31 are symmetrically arranged relative to the support rod 32. Both the support rod 32 and the support blocks 31 are in contact with the inner wall of the elastic ring 24. By changing the position of the support rod 32, the position of the support blocks 31 can be changed, thereby achieving the purpose of changing the size of the elastic ring 24. In a further embodiment, a drive shaft 33 is fixedly connected to the surface of the support rod 32, and drive grooves 34 are formed on the surface of each support block 31. The drive shaft 33 is adapted to the drive grooves 34. The drive grooves 34 are inclinedly arranged on the surface of the support block 31. When the support rod 32 slides, it can move through the drive shaft 33, which will move under the action of the drive grooves 34 and change the distance between itself and the support rod 32. In a further embodiment, a rotating column 35 is slidably connected inside the support rod 32. The rotating column 35 is rotatably disposed inside the closed ring 23. The position of the rotating column 35 on the surface of the closed ring 23 is limited by a limiting component. A spiral column 36 is fixedly connected to the surface of the rotating column 35. A spiral groove 37 is opened inside the support rod 32. The spiral column 36 is adapted to the spiral groove 37. In a further embodiment, the limiting component includes a limiting rod 38 slidably disposed on the surface of the rotating column 35, a limiting spring fixedly connected between the limiting rod 38 and the rotating column 35, and a plurality of limiting grooves 39 are formed on the surface of the closed ring 23, the limiting grooves 39 being adapted to the limiting rod 38. In some specific implementations, the support block 31 includes a control block and an extension column. The control block is fixedly connected to the extension column, and the drive groove 34 is formed on the surface of the control block. The two support blocks 31 are staggered. The two support blocks 31 are configured as a combination of a control block and an extension column, and the two support blocks 31 are staggered. During the sliding process of the two support blocks 31, the two control blocks are prevented from contacting and restricting the sliding. In some specific implementations, the fixing component includes a fixing screw 42 and a fixing nut, the fixing screw 42 and the fixing nut being threadedly connected, and the surface of the closed ring 23 having a fixing groove 41, the fixing groove 41 being adapted to the fixing screw 42; In some specific implementations, the contact ring 21 includes a placement ring and a limiting ring, both of which are semi-circular. An insertion rod 51 is fixedly connected to both ends of the placement ring, and an insertion groove 52 is provided on the surface of the limiting ring, which is adapted to the insertion rod 51. In a further embodiment, the cross-section of the insertion rod 51 is L-shaped, and the convex portion is made of elastic material; the insertion groove 52 has two openings on the surface of the limiting ring; when the insertion rod 51 is placed inside the insertion groove 52, the insertion rod 51 will automatically pop out from the non-insertion opening position and insert into the opening, thereby limiting the position. In some specific implementations, the protective tube 1 includes two semi-ring sleeves, one of which has an assembly groove at its end, and the other of which has an assembly shaft 53 fixedly connected to its end, the assembly shaft 53 being adapted to the assembly groove. The working principle of this utility model: When fixing the positions of the two protective sleeves, first, contact the two placement rings with the two protective tubes 1, then place the closing ring 23 between the two placement rings, with the elastic ring 24 in contact with the elastic rod 22. Then, pull the limiting rod 38 to disengage it from the limiting groove 39. Rotate the rotating column 35 to make the support rod 32 slide. The sliding of the support rod 32 causes the support block 31 to slide through the driving shaft 33 and the driving groove 34, changing the size of the elastic ring 24. At the same time, move the placement rings in opposite directions so that the elastic rod 22 continuously contacts the protective tube 1 and most of the elastic rod 22 contacts the protective tube 1. After the placement ring positions and the size of the elastic ring 24 are determined, release the limiting rod 38 to insert it into the limiting groove 39. Then, place two limiting rings corresponding to the placement ring positions. Place another closing ring 23 between the two limiting rings and adjust the position of the elastic ring 24 to make the elastic rod 22 contact the protective tube 1. Finally, use the fixing screw 42 and the fixing nut to limit the position of the closing ring 23.

[0022] 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.
