Specific implementation

[0027] The preferred embodiments of the utility model will be described in detail in connection with the drawings below, so that the advantages and characteristics of the utility model can be more easily understood by the person skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0028] As Figures 1-7 ​​​The MPP cable sleeve with the support assembly is shown in the embodiment, which comprises a pipe body 1 and a support assembly. The pipe body 1 is a hollow structure and is made of MPP material. Two ends of the pipe body 1 are formed with annular protrusions 2. The support assembly comprises support rods 4 and pressure receiving members 5. The opposite surfaces of the two annular protrusions 2 are processed with penetrating grooves 3. The penetrating grooves 3 are arranged along the circumferential direction of the annular protrusions 2 and are distributed on the outer side of the pipe body 1. The support rods 4 are metal rod structures with designed rigidity. The support rods 4 are installed between the two annular protrusions 2. The two ends of the support rods 4 are movably penetrated into the penetrating grooves 3 on the corresponding side, so as to be movable along the extension direction of the penetrating grooves 3 and have an assembly position which is limited to move towards or away from the pipe body 1. In the specific structure design, the penetrating groove 3 is an L-shaped groove structure with a first channel section 31 and a second channel section 32 which are communicated with each other. The width of the first channel section 31 and the second channel section 32 is matched with the outer diameter of the support rod 4, so that the support rod 4 can move back and forth between the first channel section 31 and the second channel section 32 and is limited to move in the width direction of the first channel section 31 and the second channel section 32. The extension direction of the first channel section 31 forms an angle with the radial direction of the annular protrusion 2. In the embodiment, the angle is preferably 90 degrees or less than 90 degrees. The outer circumferential surface of the annular protrusion 2 is processed with an inlet and outlet 21 for the support rod 4 to enter and exit the penetrating groove 3. The inlet and outlet 21 is formed at one end of the second channel section 32. Through the inlet and outlet 21, the support rod 4 can freely enter and exit the penetrating groove 3 to realize disassembly and assembly.

[0029] In the embodiment, a plurality of pressure receiving members 5 are installed on each support rod 4. The pressure receiving members 5 are made of plastic or metal material. The width of the pressure receiving members 5 is determined according to the actual situation. The pressure receiving members 5 comprise a sleeving part 51 sleeved on the support rod 4 and a spring structure 52 formed on the sleeving part 51. The sleeving part 51 is processed with a penetrating hole matched with the support rod 4. The sleeving part 51 is connected with the support rod 4 in clearance fit through the penetrating hole, so that the sleeving part 51 can rotate around the central axis of the support rod 4. The spring structure 52 is integrally formed with the sleeving part 51. The spring structure 52 comprises a first force arm 521 extending from the sleeving part 51 and a second force arm 522 reversely bent and extended from the end of the first force arm 521. Through the above structure design, the second force arm 522 has elastic force. When the support rod 4 is in the above assembly position, the sleeving part 51 is driven to rotate around the support rod 4, so that the sleeving part 51 has a pressure receiving position and a disengagement position. In the pressure receiving position, the second force arm 522 abuts against the outer wall of the pipe body 1, so that the second force arm 522 elastically supports the pipe body 1. In the disengagement position, the second force arm 522 is away from the pipe body 1 to release the support of the pipe body 1.

[0030] In the specific structural design, at least one U-shaped bending structure is formed between the first force arm 521 and the second force arm 522. The number of the U-shaped structures is determined according to actual needs. Through the U-shaped bending structure, the first force arm 521 has a designed elastic force. The bending direction of the second force arm 522 and the central axis direction of the sleeve part 51 are perpendicular to each other on the preset projection plane. When the sleeve part 51 rotates, the second force arm 522 can move from one side to the other side in the radial direction of the pipe body 1 and abut against the outer wall of the pipe body 1, so as to improve the smoothness when the second force arm 522 contacts the pipe body 1. The end surface of the second force arm 522 facing the pipe body 1 is processed with an anti-skid structure, so as to improve the stability when the second force arm 522 contacts the pipe body 1. The anti-skid structure is a plurality of protruding structures arranged on the second force arm 522. The protruding structures extend along the width direction of the second force arm 522.

[0031] In the embodiment, the first end of the pipe body 1 is formed with a plug-in section 12, and the second end is formed with a counterbore section 11; the outer diameter of the plug-in section 12 is matched with the inner diameter of the counterbore section 11. A plurality of groups of pipe bodies 1 are arranged along the direction of the first end and the second end of the pipe body 1, and have a butt joint state in which the first end and the second end are butt jointed. In the butt joint state, in the two adjacent pipe bodies 1, the plug-in section 12 and the counterbore section 11 are plug-in matched with each other. Through the above structural design, a plurality of groups of pipe bodies 1 can form an overall structure.

[0032] The number of the above-mentioned support rods 4 and the insertion slots 3 and other related structures is determined according to actual design, which can be four or more than four. By changing the number of the support assembly and the number of the insertion slots 3, the strength of the overall MPP cable sleeve can be changed, effectively meeting the actual application requirements of MPP cable sleeves of different pipe diameters.

[0033] In the specific assembly, the pressure bearing pieces 5 are sleeved on the support rods 4 through the sleeve joints 51. The two ends of the support rods 4 are inserted into the insertion slots 3 through the inlets and outlets 21, and the support rods 4 are pushed to move in the insertion slots 3 from the second channel sections 32 to the first channel sections 31. The positions of the pressure bearing pieces 5 on the support rods 4 are adjusted, and the pressure bearing pieces 5 are rotated to the pressure bearing positions, so that the second force arms 522 abut against the outer wall of the pipe body 1. When the support rods 4 need to be disassembled, the pressure bearing pieces 5 are rotated to the disengagement positions, and the support rods 4 are pushed to move in the insertion slots 3 and disengage from the inlets and outlets 21. The above-mentioned combination is that the support rods 4 are installed in the insertion slots 3 in the plug-in mode, so as to facilitate the disassembly and assembly of the support rods 4. The pressure bearing pieces 5 are installed on the support rods 4 in the sleeve mode, so as to facilitate the disassembly and assembly of the pressure bearing pieces 5. When the pressure bearing pieces 5 are rotated to the pressure bearing positions, the elastic sheet structures 52 on the pressure bearing pieces 5 are contracted, so that the elastic sheet structures 52 can abut against the pipe body 1 and apply elastic supporting force to the pipe body 1, thereby being capable of strengthening the support of the pipe body 1. The above-mentioned combination is that the support assemblies are externally arranged on the main body structure of the MPP cable sleeve, so as to be capable of strengthening the strength of the whole MPP cable sleeve, and the main body structure of the MPP cable sleeve is slightly changed, time and labor are saved, and the practical application requirements of the MPP cable sleeve are effectively met.

[0034] The above-mentioned is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation according to the content of the utility model specification, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
