[0001] The utility model relates to the technical field of cable protection tube production, in particular to a cable protection tube structure. Background Art

[0002] CPVC cable protection tube uses PVC-C resin with excellent heat resistance and insulation performance as the main material. It is widely used in cable laying in urban power grid construction and road and bridge engineering construction. Its excellent physical and chemical properties are receiving more and more attention from the industry. CPVC cable protection tube is spliced ​​by multiple sections during laying, and multiple pipes are docked using a docking frame. The cable protection tubes used in some existing projects are relatively long as a whole. After installation, the middle section of the pipe has a small amount of sag. After long-term use in scenes with more vibrations such as the bottom of the highway, both ends of the pipe are severely damaged by pulling, which shortens the overall service life. There is also a risk that the pipe will detach from the docking frame, which can easily cause pulling and damage to the cable. It is not convenient to provide auxiliary support for the middle sections of multiple CPVC cable protection tubes, and it is not convenient to extend the service life of the CPVC cable protection tubes, and it is not convenient to use.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 8 In an embodiment of the utility model, a cable protection tube structure includes a protection mechanism 10, and the protection mechanism 10 includes a plurality of protection tube bodies 11. Two arc plates 12 are movably clamped on the outer wall of the protection tube body 11. The two arc plates 12 are symmetrically distributed at an oblique angle. The adjacent ends of the two arc plates 12 are movably clamped. Two limiting grooves 123 are provided on the outer wall of the arc plate 12.

One end of the clamping rod 131 can be movably clamped with another adjacent docking tube 13. A limiting module 14 for reinforcing the docking of the arc plates 12 is provided inside the arc plate 12.

[0026] Specifically, by rotating and connecting a plurality of docking tubes 13 on the outer wall of the arc plate 12, the two arc plates 12 can be assembled end to end and clamped on the outer wall of the protection tube body 11, which does not affect the stacking and transportation of the protection tube body 11. After the protection tube body 11 is docked with the docking frame 20, the docking tube 13 to be used can be rotated and leaked out according to the position of the protection tube body 11, and the screw ring 132 on any of the two adjacent docking tubes 13 is rotated to leak out the clamping rod 131, so that the two docking tubes 13 are docked, so that the middle sections of the plurality of protection tube bodies 11 can be connected to each other, and the force is evenly shared, so that the installation of the protection tube body 11 is more stable and durable, and convenient to use.

[0027] Embodiment 1

[0028] like Figure 3-5 As shown, in this embodiment, docking frames 20 are provided at both ends of the protection tube body 11, and multiple fixing grooves 21 are equidistantly provided on both sides of the docking frames 20. Multiple docking grooves 111 are provided at both ends of the protection tube body 11, and the docking grooves 111 are movably connected with adjacent fixing grooves 21. An installation groove 112 is provided on the outer wall of the protection tube body 11, and two positioning grooves 113 are provided on the outer wall of the installation groove 112. An insert block 124 is fixedly connected to the inner wall of the arc plate 12, and the insert block 124 is movably connected with the adjacent positioning groove 113.

[0029] In this embodiment, the protective tube body 11 is axially positioned by cooperating with the fixing groove 21 and the docking groove 111, so that it is more stable during installation. At the same time, the positions of multiple docking tubes 13 can be limited by cooperating with the arc plate 12, so that the connection and reinforcement between multiple protective tube bodies 11 are more convenient. The installation groove 112 is used to accommodate the arc plate 12. When installing the arc plate 12, the two arc plates 12 are clamped on the outer wall of the installation groove 112 end to end, and the plug block 124 is ensured to be inserted into the positioning groove 113, so as to limit the positioning position of the two arc plates 12, and then the two arc plates 12 are docked and fixed to each other.

[0030] like Figure 6-7 As shown, in the present embodiment, a fixing screw 121 is screwed on an inner wall of the limit groove 123, and an insert rod 122 is fixedly connected to one end of the fixing screw 121. A plug hole 135 is provided on the outer wall of the butt joint 13, and the plug rod 122 can penetrate the adjacent plug hole 135 and be movably engaged with it. Two sliders 133 are symmetrically fixedly connected to the outer wall of the clamping rod 131, and the sliders 133 are slidably connected between the inner walls of the butt joint 13. A screw ring 132 is rotatably embedded on the inner wall of the butt joint 13, and the clamping rod 131 penetrates the adjacent screw ring 132 and is screwed on it. An adjusting groove 134 is provided on the outer wall of the butt joint 13.

[0031] In specific implementation, the limiting groove 123 is used to accommodate the insertion hole 135, so as to ensure that before the installation state, the stacking and transportation of the protection tube body 11 as a whole are not affected. At this time, the insertion rod 122 is stuck in the insertion hole 135, so as to limit the position of the butt joint 13 and prevent the butt joint 13 from deviating and rotating to the outside. The fixing screw 121 can be rotated to withdraw the insertion rod 122 from the insertion hole 135 to release the limit of the butt joint 13. At this time, the butt joint 13 can be rotated normally. The limiting of the slider 133 realizes the sliding limiting of the entire clamping rod 131. The screw ring 132 can be rotated by the regulating groove 134, and the clamping rod 131 is driven to move by the rotational matching between the screw ring 132 and the clamping rod 131, so as to adjust the clamping rod 131 so that the clamping rod 131 can be leaked out from the docking tube 13 to complete the clamping. Among the two adjacent clamping rods 131 on different arc plates 12, any one can be screwed out and clamped into the other docking tube 13, so as to quickly complete the docking reinforcement.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to make the connection between the two arc-shaped plates 12 faster and more stable, the arc-shaped plates 12 are not prone to abnormal separation.

[0034] like Figure 5-8 As shown, in this embodiment, the limit module 14 includes an auxiliary plate 142 fixedly connected to one end of the arc plate 12, one end of the arc plate 12 is symmetrically fixedly connected to two round blocks 141, the other end of the arc plate 12 is provided with two round holes 144 and a rectangular groove 143, the round block 141 can be movably engaged with adjacent round holes 144, the auxiliary plate 142 can be movably engaged with adjacent rectangular grooves 143, one end of the arc plate 12 is internally slidably connected with a round rod 145, the outer wall of the round rod 145 is fixedly connected with a shift block 146, the shift block 146 passes through the arc plate 12 and is slidably connected thereto, a retaining ring 147 is fixedly sleeved on the outer wall of the round rod 145, a spring 148 is fixedly connected between one side of the retaining ring 147 and the arc plate 12, one end of the round rod 145 passes through the round hole 144 and is movably engaged with the adjacent round block 141.

[0035] In specific implementation, when the two arc plates 12 are docked, they are close to each other end to end and stuck on the outer wall of the installation groove 112, and then the round block 141 is stuck into the adjacent circular hole 144, and the auxiliary plate 142 is stuck into the adjacent rectangular groove 143, so as to complete the preliminary docking of the two arc plates 12. The auxiliary plate 142 can evenly share the force, making the docking more stable. Before the adjacent ends of the two arc plates 12 are docked, the two adjacent shifting blocks 146 are moved closer to each other, so that the two round rods 145 are moved out of the circular hole 144. At this time, normal docking can be achieved. After the docking is completed, the two shifting blocks 146 are released, and the round rod 145 is driven by the spring 148 to penetrate the adjacent round blocks 141 to complete the clamping, so that the round block 141 cannot be moved out of the circular hole 144, making the connection reinforcement docking more stable.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
