[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0026] A reinforced PVC electric power protection tube according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 5 As shown, a reinforced PVC electric power protection tube according to an embodiment of the utility model may include a first tube body 1 , a connecting portion 11 and a mounting portion 12 .

[0028] Among them, the connecting part 11 may include an outer ring seat 111, and the mounting part 12 may include an inner ring seat 121. The outer ring seat 111 and the inner ring seat 121 are respectively arranged on the outer surfaces of both ends of the first tube body 1, and the inner ring seat 121 is located inside the outer ring seat 111 in an adjacent group of first tube bodies 1, and is slidably connected to the inner wall of the outer ring seat 111.

[0029] It should be noted that the outer diameter of the inner ring seat 121 matches the inner diameter of the outer ring seat 111 .

[0030] A limiting protrusion 122 and a limiting groove 112 are respectively arranged at the outer edge of the inner ring seat 121 corresponding to the inner wall position of the outer ring seat 111. The limiting protrusion 122 is slidably connected to the inner wall of the limiting groove 112. An opening groove 113 is opened at the outer surface of the outer ring seat 111 corresponding to the position of the limiting groove 112. The opening groove 113 is connected to the inside of the limiting groove 112.

[0031] It can be understood that the limiting protrusion 122 enters the limiting slide groove 112 through the opening groove 113, and the rotation of the first tube body 1 and the inner ring seat 121 will synchronously drive the limiting protrusion 122 to move on the inner wall of the limiting slide groove 112. The limiting protrusion 122 and the limiting slide groove 112 cooperate with each other to achieve a quick connection between the two groups of first tube bodies 1. When the limiting protrusion 122 moves to the end of one end of the limiting slide groove 112 and abuts against the inner wall of the limiting slide groove 112, the position of the first tube body 1 and the inner ring seat 121 is limited and the rotation is stopped.

[0032] An elastic clamp 114 and a limit clamp block 123 are respectively provided at corresponding positions of the outer surface of the outer ring seat 111 and the outer surface of the inner ring seat 121 , and one end of the elastic clamp 114 is clamped and fixed to the limit clamp block 123 .

[0033] It should be noted that the elastic clamp 114 and the limiting clamp block 123 cooperate with each other to effectively prevent the two groups of first tube bodies 1 from rotating, and the use effect is good.

[0034] Specifically, when in use, align one end of the adjacent group of first tube bodies 1 with the mounting portion 12 with one end of the first group of first tube bodies 1 with the connecting portion 11. After alignment, insert one end of the adjacent group of first tube bodies 1 with the mounting portion 12 into one end of the first group of first tube bodies 1 with the connecting portion 11. During the insertion process, ensure that the limiting protrusion 122 is aligned with the opening groove 113. After the end of the adjacent group of first tube bodies 1 with the mounting portion 12 is inserted, the inner ring seat 121 is located inside the outer ring seat 111, and the limiting protrusion 122 enters the limiting sliding groove 112 through the opening groove 113, and then Rotate an adjacent group of first tube bodies 1, and the rotation of an adjacent group of first tube bodies 1 synchronously drives the inner ring seat 121 and the limiting protrusion 122 to rotate, the inner ring seat 121 rotates and slides on the inner wall of the outer ring seat 111, and the limiting protrusion 122 rotates and slides toward the other end of the limiting slide groove 112, and the two groups of first tube bodies 1 can be quickly connected through the cooperation between the limiting protrusion 122 and the limiting slide groove 112. When the limiting protrusion 122 moves to the end of one end of the limiting slide groove 112 and abuts against the inner wall of the limiting slide groove 112, the position of the adjacent group of first tube bodies 1 and the inner ring seat 121 is limited and the rotation is stopped.

[0035] In order to ensure that the position of the limiting protrusion 122 inside the limiting slide groove 112 remains unchanged and to ensure the connection stability, an elastic clamp head 114 and a limiting clamp block 123 are specially provided. The elastic clamp head 114 and the limiting clamp block 123 are respectively installed on the surface of the outer ring seat 111 and the surface of the inner ring seat 121. When the inner ring seat 121 rotates, the limiting clamp block 123 is simultaneously driven to rotate. When the position of the inner ring seat 121 is limited and stops rotating, the limiting clamp block 123 moves to the position of the elastic clamp head 114 and is clamped and fixed with one end of the elastic clamp head 114. The elastic clamp head 114 and the limiting clamp block 123 cooperate with each other, thereby effectively preventing the first tube body 1 from rotating and ensuring the connection stability.

[0036] During this process, the end of the first tube body 1 of the first group with the connecting portion 11 needs to be kept in a fixed state.

[0037] The overall operation of the device is simple, and it is convenient to disassemble and assemble for use, thereby effectively improving work efficiency.

[0038] In one embodiment of the present invention, Figure 1 As shown, the number of limiting protrusions 122, limiting slide grooves 112, opening grooves 113, elastic clamps 114 and limiting blocks 123 is equal, and the number of limiting protrusions 122, limiting slide grooves 112, opening grooves 113, elastic clamps 114 and limiting blocks 123 is at least four groups.

[0039] Specifically, the number of the limiting protrusions 122 , the limiting sliding grooves 112 , the opening grooves 113 , the elastic clamps 114 and the limiting clamping blocks 123 is further limited, and four or more groups can further ensure the connection stability and achieve good use effect.

[0040] In one embodiment of the present invention, Figure 4 As shown, the limiting block 123 may include a block body 1231 , a locking hole 1232 and a tapered groove 1233 .

[0041] Among them, the block 1231 is arranged on the outer surface of the inner ring seat 121, the clamping hole 1232 is opened on the surface of the block 1231, and the conical groove 1233 is opened on the side surface of the block 1231 close to the elastic clamp head 114. One end of the elastic clamp head 114 enters the clamping hole 1232 through the conical groove 1233 and is clamped and fixed with the clamping hole 1232.

[0042] It should be noted that the design of the tapered groove 1233 described in this embodiment facilitates the retraction of one end of the elastic clamp 114 so that it can enter the interior of the clamp hole 1232 more easily.

[0043] Specifically, the structure and connection relationship of the limit block 123 are further explained. The limit block 123 moves synchronously with the rotation of the inner ring seat 121. When the limit block 123 contacts one end of the elastic clamp 114, the elastic clamp 114 is squeezed and retracted by the conical groove 1233. When the elastic clamp 114 moves to the internal position of the clamping hole 1232, the squeezing force disappears, and the elastic clamp 114 enters the inside of the clamping hole 1232 under the action of the elastic force, thereby being clamped and fixed with the clamping hole 1232.

[0044] In one embodiment of the present invention, Figure 3 As shown, a sealing ring 124 is sleeved on the surface of the first tube body 1 and is located on one side of the inner ring seat 121 .

[0045] It should be noted that the design of the sealing ring 124 described in this embodiment improves the sealing performance of the connection and has a good use effect.

[0046] In one embodiment of the present invention, Figure 5 As shown, a convenient disassembly mechanism 13 is disposed on the surface of the first tube body 1 , and the convenient disassembly mechanism 13 includes a guide rail 131 , a ring frame 132 and a protruding rod 133 .

[0047] The guide rail 131 is arranged on the surface of the first tube body 1 , the ring frame 132 is slidably connected to the surface of the guide rail 131 and sleeved on the outside of the first tube body 1 , and the protruding rod 133 is arranged on the surface of the ring frame 132 and corresponds to the position of the clamping hole 1232 .

[0048] It should be noted that the easy disassembly mechanism 13 described in this embodiment is used to quickly separate the two groups of first tube bodies 1 .

[0049] It should be noted that a limiting portion (not shown in the figure) is provided on the guide rail 131 , and the limiting portion is provided to limit the travel of the ring frame 132 and prevent it from falling off the guide rail 131 .

[0050] Specifically, when the outer ring seat 111 needs to be separated from the inner ring seat 121, the ring frame 132 is pushed to move along the surface of the guide rail 131 toward the side of the inner ring seat 121. When the protruding rod 133 enters the clamping hole 1232 and squeezes the elastic clamping head 114 to retract, the first tube body 1 is rotated to separate the elastic clamping head 114 from the limiting clamping block 123. The operation is simple and the use effect is good.

[0051] In summary, the reinforced PVC electric power protection tube of the embodiment of the utility model can realize the quick connection between the outer ring seat 111 and the inner ring seat 121 through the cooperation between the limiting protrusion 122 and the limiting slide groove 112, and the rotation angle of the first tube body 1 can be limited by the cooperation between the elastic clamp 114 and the limiting clamp block 123 to prevent it from rotating and ensure the connection stability. The elastic clamp 114 can be quickly separated from the limiting clamp block 123 through the convenient disassembly mechanism 13, which is convenient for the disassembly and assembly of the two groups of first tube bodies 1. The overall operation is simple, easy to disassemble and use, and effectively improves work efficiency.
