Description

Technical Field

[0001] This utility model relates to the field of protection tube technology, and in particular to a power protection tube. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent damage. Cable protection pipes are mainly installed at the intersection of communication cables and power lines to prevent short circuit accidents caused by power line breaks, which could cause communication cables and steel wire ropes to become energized, thus protecting cables, switches, circuit boards, and even the entire machine from being burned out. They also play a certain role in isolating magnetic field interference from power lines. However, conventional power protection pipes are not convenient for splicing and installation.

[0003] The existing patent CN209267035U MPP power protection tube involves splicing two protection tube bodies by connecting the groove end and the slider end. When the two protection tube bodies are fully overlapped, the compression spring pushes out the ball bearing through its elastic force, causing the ball bearing to align with the positioning hole. This fixes the position of the two protection tube bodies during connection, preventing misalignment during splicing. To disassemble the two protection tube bodies, pressing a button moves the push rod, which pushes the ball bearing out of the positioning hole, allowing the groove and slider to be disassembled. When placing the protection tube body, the support plate opens around the axis of rotation, supporting the protection tube body and preventing it from rolling. The insulation layer improves the insulation of the protection tube body, and the polyvinyl chloride coating protects the outside of the protection tube body and slows down the corrosion rate.

[0004] However, in the process of using the above method, the device locks the slider and the slide groove by inserting the ball connected to the compression spring into the positioning hole, thereby locking the two sets of protective tubes. However, if the protective tube is vibrated, the compression spring will undergo elastic deformation, which makes the ball easily disengage from the positioning hole, thereby causing the connection between the two sets of protective tubes to loosen or even fall off. Utility Model Content

[0005] The purpose of this utility model is to provide an electric protection tube that solves the problem of the aforementioned device locking the slider and the slide groove by inserting a ball connected to the compression spring into the positioning hole, thereby locking the two sets of protection tubes. However, if the protection tube is vibrated, the compression spring will undergo elastic deformation, which makes the ball easily disengage from the positioning hole, resulting in loosening or even detachment of the connection between the two sets of protection tubes.

[0006] To achieve the above objectives, this utility model provides a power protection pipe, comprising a pipe body, a first splicing sleeve, a second splicing sleeve, and a partition device. The first splicing sleeve is fixedly installed on the pipe body and has a first stop block. The second splicing sleeve is fixedly installed on the side of the pipe body near the first splicing sleeve and has a second stop block. The partition device is installed inside the pipe body. The device also includes a splicing device, comprising a splicing block, a guide cylinder, a locking rod, a rotating assembly, and a preliminary positioning assembly. The splicing block is fixedly installed on the pipe body and located at the end of the pipe body away from the first splicing sleeve. The guide cylinder is fixedly installed on the first splicing sleeve and communicates with it. The locking rod is threadedly engaged with the guide cylinder. The rotating assembly is disposed on the locking rod. The preliminary positioning assembly is disposed on the pipe body.

[0007] The rotating assembly includes a rotating disk and an arc block, wherein the rotating disk is fixedly mounted on the clamping rod, and the arc block is fixedly mounted on the rotating disk.

[0008] The initial positioning component includes a positioning rod and an annular groove. The annular groove is located on the side of the tube body near the first splicing sleeve. The positioning rod is fixedly installed on the side of the tube body away from the annular groove.

[0009] The partition device includes a partition rod and a limiting block. The partition rod is fixedly installed inside the tube, and the limiting block is fixedly installed on the partition rod.

[0010] The partition device also includes a protective sleeve, which is fixedly installed on the partition rod.

[0011] This utility model discloses a power protection pipe. When the pipe bodies are spliced, the positioning rods of one set of pipe bodies are aligned with the annular grooves of another set of pipe bodies, and the positioning rods are inserted into the annular grooves. Then, the left-side pipe body is rotated counterclockwise, causing the two sets of splicing blocks on the left-side pipe body to rotate into the first splicing sleeve and the second splicing sleeve respectively, until the splicing blocks abut against the first stop block and the second stop block respectively. At this time, rotating the arc block drives the rotating disk to rotate, causing the rotating disk to drive the locking rod to rotate. Since the locking rod is threadedly connected to the guide cylinder, the locking rod is pushed along the guide cylinder towards the first splicing sleeve until the locking rod is locked above the splicing block in the first splicing sleeve, thereby preventing the splicing block from detaching from the first splicing sleeve and the second splicing sleeve, and realizing the stable splicing of the two sets of pipe bodies.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows:

[0018] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a power protection pipe according to this utility model. Figure 2 This is a schematic diagram of the partition device of this utility model.

[0019] This utility model provides a power protection tube, comprising a tube body 101, a first splicing sleeve 102, a second splicing sleeve 103, and a partition device, and also includes a splicing device, which includes a splicing block 106, a guide cylinder 107, a locking rod 108, a rotating assembly, and a preliminary positioning assembly. The rotating assembly includes a rotating disk 109 and an arc block 110. The preliminary positioning assembly includes a positioning rod 111 and an annular groove 112. The partition device includes a partition rod 113 and a limiting block 114. The partition device also includes a protective sleeve 115. The aforementioned solution solves the problem that the aforementioned device locks the slider and the groove by inserting a ball connected to a compression spring into the positioning hole, thereby locking the two sets of protection tubes. However, if the protection tube is vibrated, the compression spring will undergo elastic deformation, which makes it easy for the ball to detach from the positioning hole, resulting in loosening or even detachment of the connection between the two sets of protection tubes.

[0020] In this embodiment, the rotating component drives the locking rod 108 to move into the guide cylinder 107, so that the locking rod 108 is locked above the splicing block 106 in the first splicing sleeve 102, thereby preventing the splicing block 106 from disengaging from the first splicing sleeve 102 and the second splicing sleeve 103, and realizing the stable splicing of the two sets of tubes 101.

[0021] The splicing block 106 is fixedly installed on the pipe body 101 and located at the end of the pipe body 101 away from the first splicing sleeve 102. The guide cylinder 107 is fixedly installed on the first splicing sleeve 102 and communicates with the first splicing sleeve 102. The clamping rod 108 is threadedly engaged with the guide cylinder 107. The rotating component is disposed on the clamping rod 108. The initial positioning component is disposed on the pipe body 101. The splicing block 106 is fixed to the outside of the pipe body 101 by screws. The guide cylinder 107 has internal threads, and the clamping rod 108 has external threads (not shown in the figure). At that time, the initial positioning component is used to position the two sets of tubes 101. By rotating the left tube 101 counterclockwise, the splicing blocks 106 on both sides are rotated into the first splicing sleeve 102 and the second splicing sleeve 103 respectively. The rotating component drives the locking rod 108 to be pushed into the guide cylinder 107, so that the locking rod 108 is locked above the splicing block 106 in the first splicing sleeve 102, thereby preventing the splicing block 106 from disengaging from the first splicing sleeve 102 and the second splicing sleeve 103, and realizing the stable splicing of the two sets of tubes 101.

[0022] Secondly, the rotating disk 109 is fixedly installed on the clamping rod 108; the arc block 110 is fixedly installed on the rotating disk 109, the rotating disk 109 is welded to the end of the clamping rod 108, and the arc block 110 is arranged in a ring on the outside of the rotating disk 109. By rotating the arc block 110, the rotating disk 109 is rotated, thereby causing the rotating disk 109 to drive the clamping rod 108 to rotate.

[0023] Furthermore, the annular groove 112 is disposed on the side of the tube body 101 near the first splicing sleeve 102; the positioning rod 111 is fixedly installed on the side of the tube body 101 away from the annular groove 112, and the positioning rod 111 is disposed on both sides of the end of the tube body 101. The length of the positioning rod 111 is the same as the depth of the annular groove 112. By inserting the positioning rod 111 into the annular groove 112, the initial positioning of the two sets of tube bodies 101 when splicing can be achieved.

[0024] Furthermore, the partition rod 113 is fixedly installed inside the tube body 101; the limiting block 114 is fixedly installed on the partition rod 113. The partition rod 113 is arranged in a ring inside the tube body 101, and the limiting block 114 is welded to the bottom end of the partition rod 113. Through the setting of the partition rod 113, the cables inside the tube body 101 can be separated to avoid entanglement between the cables.

[0025] Finally, the protective sleeve 115 is fixedly installed on the partition rod 113. The protective sleeve 115 is fixed to the partition rod by adhesive. The protective sleeve 115 is made of sponge material. The protective sleeve 115 can reduce the wear between the partition rod 113 and the cable.

[0026] In this embodiment, when the tube bodies 101 are spliced, the positioning rods 111 of one set of tube bodies 101 are aligned with the annular grooves 112 of another set of tube bodies 101, and the positioning rods 111 are inserted into the annular grooves 112. Then, the left tube body 101 is rotated counterclockwise, so that the two sets of splicing blocks 106 on the left tube body 101 rotate into the first splicing sleeve 102 and the second splicing sleeve 103 respectively, until the splicing blocks 106 abut against the first stop block 104 and the second stop block 105 respectively. At this time, The rotation of the arc block 110 drives the rotating disk 109 to rotate, which in turn drives the locking rod 108 to rotate. Since the locking rod 108 is threadedly connected to the guide cylinder 107, the locking rod 108 is pushed along the guide cylinder 107 towards the first splicing sleeve 102 until the locking rod 108 is locked above the splicing block 106 inside the first splicing sleeve 102. This prevents the splicing block 106 from disengaging from the first splicing sleeve 102 and the second splicing sleeve 103, thus achieving stable splicing of the two sets of pipe bodies 101.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
