[0025] The schemes in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features.

[0026] In view of the technical defects in the related art, the present application provides a self-adaptive protection tube, please refer to Figures 1 to 4 The self-adaptive protection tube comprises a strip body 100, an insertion slot 200 and at least two clamping structures. The strip body 100 has two long edge ends 110 extending along the length direction thereof and two short edge ends 120 extending along the width direction thereof. The length of the strip body 100 can be determined according to the length of the optical cable 600 to be wrapped. The insertion slot 200 is arranged on one long edge end 110 of the strip body 100 and is throughly arranged. The other long edge end 110 of the strip body 100 can pass through the insertion slot 200, so that the strip body 100 forms a tubular cavity 130, and the two short edge ends 120 surround the two ports of the tubular cavity 130.

[0027] That is, when it is necessary to wrap the optical cable 600 with the protection tube, the optical cable 600 can be gathered together, then wrapped with the strip body 100, and then one long edge end 110 of the strip body 100 is inserted into the insertion slot 200 arranged on the other long edge end 110, so that the optical cable 600 can be located in the tubular cavity 130. In this way, the length of the strip body 100 passing through the insertion slot 200 can be adjusted to adapt to the wrapping of different numbers of optical cables 600, so that the protection tube can self-adaptively meet the laying requirements of different numbers of optical cables 600, thereby avoiding the problem of frequent replacement of the traditional fixed pipe diameter, and significantly improving the applicability and construction efficiency of the protection tube.

[0028] Further, at least two clamping structures are arranged on the insertion slot 200 in a spaced manner along the length direction of the insertion slot 200, and each clamping structure is used for clamping the part of the strip-shaped sheet body 100 passing through the insertion slot 200. The use of the clamping structure can make the strip-shaped sheet body 100 keep a stable form after bending adjustment.

[0029] The specific arrangement structure of the clamping structure for clamping the strip-shaped sheet body 100 has various designs. For example, in the embodiment, the clamping structure includes a clamping piece 300 and a plurality of clamping blocks 400. The clamping piece 300 is rotatably arranged at the slot opening of the insertion slot 200, each clamping block 400 is arranged on the surface of the strip-shaped sheet body 100, each clamping block 400 is arranged in a spaced manner along the width direction of the strip-shaped sheet body 100, and the clamping piece 300 is used for clamping the corresponding clamping block 400. In this way, the cooperation of the clamping piece 300 and the different clamping blocks 400 makes the inner diameter adjustment operation of the tubular cavity 130 formed by the strip-shaped sheet body 100 more convenient.

[0030] For another example, in another embodiment, the clamping structure can include a pressing block and an elastic piece. One end of the elastic piece is arranged on the side of the insertion slot 200 facing the strip-shaped sheet body 100, and the other end of the elastic piece is connected with the pressing block. When the strip-shaped sheet body 100 passes through the insertion slot 200, the pressing block can be supported by the elastic support force of the elastic piece on the part of the strip-shaped sheet body 100 located in the insertion slot 200, so that the strip-shaped sheet body 100 can keep a stable form after bending adjustment.

[0031] Through the above technical solutions, the self-adaptive protection tube of the utility model is arranged with the insertion slot 200 on the strip-shaped sheet body 100, so that the one end of the strip-shaped sheet body 100 can be inserted and matched with the insertion slot 200 to form the tubular cavity 130, and at least two clamping structures are arranged on the strip-shaped sheet body 100 for clamping the part of the strip-shaped sheet body 100 passing through the insertion slot 200. In this way, the inner diameter of the tubular cavity 130 formed by the strip-shaped sheet body 100 can be adjusted and wrapped around different numbers of optical cables 600, the laying requirements of different numbers of optical cables 600 can be met, the problem that the traditional fixed pipe diameter needs to be frequently replaced is avoided, and the applicability and construction efficiency of the protection tube are significantly improved. In addition, the arrangement of the clamping structure can ensure that the tubular cavity 130 keeps a stable form after adjustment, and prevent the strip-shaped sheet body 100 from rebounding or deforming due to external force.

[0032] It should be noted that each clamping block 400 can be separately arranged on the strip-shaped sheet body 100 by means of adhesion, ultrasonic welding or other connection methods, or each clamping block 400 can be integrally formed with the strip-shaped sheet body 100. The specific connection method of each clamping block 400 with the strip-shaped sheet body 100 is not limited herein.

[0033] In order to facilitate the construction personnel to adjust the inner diameter of the tubular cavity 130, in the embodiment, the clamping piece 300 has a clamping end 310 and a pressing end 320, the clamping end 310 is clamped with the corresponding clamping block 400, and the pressing end 320 can make the clamping end 310 and the corresponding clamping block 400 disengage under the action of external force. In this way, when the construction personnel needs to adjust the inner diameter of the tubular cavity 130, they only need to press the pressing end 320 of the clamping piece 300 to make the clamping end 310 and the corresponding clamping block 400 disengage, and then pull out the strip-shaped piece 100 in the insertion slot 200 to adjust the tubular cavity 130. At this time, the adjustment can be to increase the inner diameter of the tubular cavity 130 to adapt to more optical cables 600, or to reduce the inner diameter of the tubular cavity 130 to adapt to fewer optical cables 600. Through the pressing disengagement design of the clamping end 310, the construction personnel can quickly unlock without the help of tools, which is convenient for adjustment and disassembly, and significantly reduces the maintenance difficulty.

[0034] In addition, in order to facilitate the setting of the clamping piece 300, in the embodiment, the clamping piece 300 is made of plastic material, and the clamping piece 300 has a certain elastic deformation ability. When the pressing end 320 of the clamping piece 300 is pressed, the clamping piece 300 itself can make the clamping end 310 and the clamping block 400 separate due to its certain elastic deformation ability. Similarly, after the force on the pressing end 320 is removed, the clamping piece 300 can continue to clamp the corresponding clamping block 400 through its elastic deformation.

[0035] In the embodiment, at least two clamping structures are arranged at both ends of the length direction of the strip-shaped piece 100. The clamping structures at both ends of the length direction of the strip-shaped piece 100 can form multi-point balanced force, ensure the overall structural stability of the tubular cavity 130, and effectively prevent the protective tube from loosening.

[0036] In addition, the two short edge ends 120 of the strip-shaped piece 100 are both provided with thickened layers for edge sealing. The thickened layer edge sealing of the short edge end 120 can enhance the compression strength and crack resistance of the port, and prevent the edge from cracking or wearing when the optical cable 600 is threaded.

[0037] In the embodiment, the slot length of the insertion slot 200 is greater than the length of the long edge end 110 of the strip-shaped piece 100. The redundant design that the slot length of the insertion slot 200 is greater than the length of the long edge end 110 of the strip-shaped piece 100 makes the long edge end 110 of the strip-shaped piece 100 more easily pass through the slot of the insertion slot 200, which is convenient for the construction personnel to thread.

[0038] Further, the strip-shaped piece 100 of the embodiment is made of polyurethane material, and a waterproof layer is coated on the surface of the strip-shaped piece 100, the polyurethane material endows the strip-shaped piece 100 with excellent flexibility, elastic deformation capability, corrosion resistance and anti-aging performance, so that the strip-shaped piece 100 is suitable for harsh environments such as high and low temperature, humidity or chemical corrosion, reduces the risk of pipe body cracking, the surface waterproof layer further blocks the penetration of moisture, avoids the condensation of the inner wall of the pipe body or the dampening of the optical cable 600, and improves the long-term protection capability of the protection pipe in the rain, underground humid environment.

[0039] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
