Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a high-compression-resistant HDPE silicon core pipe. Background Technology

[0002] Silicon core pipe is a new type of composite pipe with a silicone solid lubricant on its inner wall. Its full name is high-density polyethylene silicon core pipe. It is made of HDPE as the main raw material, with the addition of appropriate additives, and is manufactured by extrusion molding. HDPE has excellent properties of corrosion resistance, aging resistance and environmental stress cracking resistance, which can ensure the long-term use of the pipe under different environmental conditions. It is widely used in optical cable laying projects in the fields of communication and power. In communication engineering, it is often used as a protective pipe for optical cables of long-distance communication, local network communication and cable TV network. In power engineering, it can be used as a protective sleeve for power cables for urban power grid transformation and power construction projects in industrial parks.

[0003] A search revealed Chinese Patent Publication No. CN220475325U, which discloses a high-compression-resistant HDPE silicon core tube, comprising a main body structure, a compression-resistant structure, and a fixing structure. The compression-resistant structure is located inside the main body structure, and the fixing structure is located on the outer ring of the main body structure. The main body structure includes an outer HDPE silicon core tube, an anti-corrosion layer, and an inner HDPE silicon core tube. The outer ring of the anti-corrosion layer is fixedly connected to the inner ring of the outer HDPE silicon core tube, and the inner HDPE silicon core tube is located inside the outer HDPE silicon core tube. The compression-resistant structure includes a first supporting compression-resistant layer and a first supporting plate. The high-pressure-resistant HDPE silicon core pipe consists of a support block, a second support and pressure-resistant layer, a second support plate, an outer buffer layer, an inverted triangular rack, an inner buffer layer, an equilateral triangular rack, a first rubber pad, and a second rubber pad. The outer ring of the first support and pressure-resistant layer is fixedly connected to the inner ring of the anti-corrosion layer. Through the structure of the anti-corrosion layer, the high-pressure-resistant HDPE silicon core pipe can avoid corrosion of the silicon core pipe when buried underground for a long time during actual use. However, when subjected to external pressure, temperature changes, or soil stress, separation and sliding phenomena may easily occur between the layers, leading to the failure of the overall structure and affecting the pressure resistance and anti-corrosion performance of the silicon core pipe. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a high-compression-resistant HDPE silicon core pipe, aiming to improve the problem of interlayer separation in the existing technology, which affects the compression resistance and corrosion resistance of the silicon core pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-compression-resistant HDPE silicon core pipe, comprising an inner pipe, a buffer layer fixedly connected to the outer wall of the inner pipe, multiple buffer foams equidistantly installed on the outer wall of the buffer layer, multiple buffer columns equidistantly installed on the outer wall of the buffer layer, multiple telescopic rods equidistantly fixedly connected around the outer wall of the buffer columns, springs provided on the outer wall of the telescopic rods, and a pressure-resistant outer pipe fixedly connected to the ends of the multiple telescopic rods, with a fixing mechanism provided on the adjacent side of the outer wall of two pressure-resistant outer pipes, the fixing mechanism being used to fix the inner pipe.

[0006] Through the above technical solution: when the HDPE silicon core pipe is subjected to external force, the pressure-resistant outer pipe first bears the pressure, and then transmits the force to the telescopic rod. The telescopic rod then contracts inward, compressing the spring. The spring generates a reverse elastic force to offset part of the pressure. At the same time, the buffer column and the buffer foam absorb the impact energy through their own deformation, while the buffer layer further disperses and buffers the pressure. Through the combined action of these multiple buffer structures, the adverse effects of external force on the inner pipe and its internal cables can be significantly reduced, ensuring that the internal silicon core layer and cables can still maintain their excellent performance and structural integrity when subjected to greater pressure. A fixing mechanism is set on the adjacent side of the outer wall of the two pressure-resistant outer pipes to fix the inner pipe.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a lower clamp body, which is disposed on an adjacent side of the outer wall of the two pressure-resistant outer tubes. An upper clamp body is disposed on the top wall of the lower clamp body. A connecting block one is fixedly connected to the rear side of the outer wall of the lower clamp body, and a connecting block two is fixedly connected to the rear side of the outer wall of the upper clamp body. The connecting block one and the connecting block two are rotatably connected. A locking block is rotatably connected to the middle of the front side of the outer wall of the lower clamp body, and a fixing block is fixedly connected to the middle of the front side of the outer wall of the upper clamp body. A locking groove is provided on the right side of the outer wall of the fixing block, and the locking block engages with the locking groove.

[0009] The above technical solution involves placing the pressure-resistant outer tube onto the lower clamp, rotating the upper clamp to cause the connecting block 2 of the upper clamp to rotate and close within the connecting block 1 of the lower clamp, and then rotating the locking block at the front end of the lower clamp to engage with the locking groove on the fixing block at the front end of the upper clamp, thereby locking the upper and lower clamps and ensuring that the two pressure-resistant outer tubes are tightly clamped, achieving a stable fixation of the pressure-resistant outer tubes, ensuring the stability of the pipe position during use, and avoiding unnecessary displacement or loosening.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the pressure-resistant outer tube is fixedly connected with an anti-corrosion layer.

[0012] Through the above technical solution, the anti-corrosion layer can isolate the pressure-resistant outer pipe from external corrosive substances, prevent the pipe from being chemically corroded, and thus extend the service life of the pipe.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the pressure-resistant outer tube is fixedly connected to protective layers on both the left and right sides.

[0015] Through the above technical solution, the protective layer provides additional protection to the left and right sides of the pressure-resistant outer pipe, reducing the risk of pipe rupture or decreased pressure resistance due to mechanical damage.

[0016] As a further description of the above technical solution:

[0017] A sealing gasket is provided on each adjacent side of the outer wall of the two protective layers.

[0018] The above technical solution uses a sealing gasket to prevent external water, air, dust, and substances from entering the pipe.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the anti-corrosion layer is provided with marking lines.

[0021] Through the above technical solutions, the marking lines can provide clear identification for construction or maintenance personnel, which helps to correctly carry out construction, installation, and subsequent maintenance management.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the card block is fitted with an anti-slip sleeve.

[0024] The above technical solution uses an anti-slip sleeve to increase the friction between the hand and the locking block, allowing the operator to rotate the locking block more steadily.

[0025] As a further description of the above technical solution:

[0026] A rubber pad is installed on the front side of the top wall of the lower clamp.

[0027] Through the above technical solution, the rubber pad is used to provide stability and fixation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the HDPE silicon core pipe is subjected to external force, the pressure-resistant outer pipe first bears the pressure and transmits it to the telescopic rod. The telescopic rod compresses the spring to generate a reverse elastic force. The buffer column and buffer foam absorb the impact energy, and the buffer layer disperses the pressure. The multiple buffer structures work together to reduce the impact of external force on the inner pipe and cable, protect the silicon core layer and cable, and enable them to maintain good performance and integrity even when subjected to greater pressure.

[0030] 2. In this utility model, the pressure-resistant outer tube is placed in the lower clamping body, and the upper clamping body is rotated. The connecting block 2 of the upper clamping body rotates inside the connecting block 1 of the lower clamping body to close it. The locking block and the fixing block cooperate with the locking groove to achieve a stable fixation of the pressure-resistant outer tube, ensuring that the tube is stable in position during use and will not easily shift or loosen.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-pressure resistant HDPE silicon core pipe, comprising an inner pipe 1, which directly accommodates and protects the silicon core layer and internal cables. A buffer layer 3 is fixedly connected to the outer wall of the inner pipe 1, absorbing and dispersing external impact forces. Multiple buffer foams 4 are equidistantly installed on the outer wall of the buffer layer 3, further absorbing and buffering impact forces to reduce the overall pressure on the pipe and protect the internal structure. Multiple buffer pillars 5 are equidistantly installed on the outer wall of the buffer layer 3, resisting a certain degree of external force. Multiple telescopic rods 6 are equidistantly fixedly connected around the outer wall of the buffer pillars 5, with springs 7 installed on the outer wall of each telescopic rod 6. The telescopic rods 6 and springs 7 are used to resist external forces from multiple directions. To resist external pressure, the pipe has good pressure resistance in all directions. The ends of multiple telescopic rods 6 are fixedly connected to pressure-resistant outer pipes 8. The pressure-resistant outer pipes 8 have high rigidity and pressure resistance. The outer walls of two pressure-resistant outer pipes 8 are provided with fixing mechanisms 2 on adjacent sides. The fixing mechanisms 2 are used to fix the inner pipe 1. The outer walls of the pressure-resistant outer pipes 8 are fixedly connected with anti-corrosion layers 9. The anti-corrosion layers 9 can isolate the pressure-resistant outer pipes 8 from external corrosive substances, avoid chemical corrosion of the pipe, and thus extend the service life of the pipe. The outer walls of the pressure-resistant outer pipes 8 are fixedly connected with protective layers 10 on the left and right sides. The protective layers 10 are used to provide additional protection for the left and right sides of the pressure-resistant outer pipes 8 and reduce the risk of pipe rupture or decreased pressure resistance due to mechanical damage.

[0041] Specifically, when the HDPE silicon core pipe encounters external force, the pressure-resistant outer pipe 8 first bears the pressure and then transmits the force to the telescopic rod 6. The telescopic rod 6 then contracts inward, compressing the spring 7. The spring 7 generates a reverse elastic force to offset part of the pressure. At the same time, the buffer column 5 and the buffer foam 4 absorb the impact energy through their own deformation, while the buffer layer 3 further disperses and buffers the pressure. Through the combined action of these multiple buffer structures, the adverse effects of external force on the inner pipe 1 and its internal cables can be significantly reduced, thereby protecting the internal silicon core layer and cables. This ensures that even under greater pressure, it can still maintain its excellent performance and structural integrity. The outer walls of the two pressure-resistant outer pipes 8 are provided with a fixing mechanism 2 on adjacent sides. The fixing mechanism 2 is used to fix the inner pipe 1. The anti-corrosion layer 9 can isolate the pressure-resistant outer pipe 8 from external corrosive substances, preventing the pipe from being chemically corroded, thereby extending the service life of the pipe. The protective layer 10 is used to provide additional protection for the left and right sides of the pressure-resistant outer pipe 8, reducing the risk of pipe rupture or decreased pressure resistance due to mechanical damage.

[0042] Reference Figure 2 , Figure 5 and Figure 6 The fixing mechanism 2 includes a lower clamping body 201, which is disposed on the adjacent side of the outer wall of the two pressure-resistant outer tubes 8. An upper clamping body 202 is disposed on the top wall of the lower clamping body 201. A connecting block 1 203 is fixedly connected to the rear side of the outer wall of the lower clamping body 201, and a connecting block 204 is fixedly connected to the rear side of the outer wall of the upper clamping body 202. The connecting block 1 203 and the connecting block 204 are rotatably connected. Rotating the upper clamping body 202 causes the connecting block 204 of the upper clamping body 202 to rotate and close within the connecting block 1 203 of the lower clamping body 201. A locking block 205 is rotatably connected to the middle of the front side of the outer wall of the lower clamping body 201, and the middle of the front side of the outer wall of the upper clamping body 202 is rotatably connected to the locking block 205. A fixing block 206 is fixedly connected to the lower clamp 201. A slot 207 is provided on the right side of the outer wall of the fixing block 206. The locking block 205 engages with the slot 207. The locking block 205 at the front end of the lower clamp 201 is rotated so that it engages with the slot 207 on the fixing block 206 at the front end of the upper clamp 202, thereby locking the upper clamp 202 and the lower clamp 201. An anti-slip sleeve 13 is installed on the outer wall of the locking block 205. The anti-slip sleeve 13 is used to increase the friction between the hand and the locking block 205, so that the operator can rotate the locking block 205 more stably. A rubber pad 14 is installed on the front side of the top wall of the lower clamp 201. The rubber pad 14 is used to stabilize and fix the clamp.

[0043] Specifically, the pressure-resistant outer tube 8 is placed on the lower clamp 201, and the upper clamp 202 is rotated so that the connecting block 204 of the upper clamp 202 rotates and closes inside the connecting block 203 of the lower clamp 201. Then, the locking block 205 at the front end of the lower clamp 201 is rotated so that it engages with the slot 207 on the fixing block 206 at the front end of the upper clamp 202, thereby locking the upper clamp 202 and the lower clamp 201. In this way, the two pressure-resistant outer tubes 8 are tightly clamped to ensure their stable fixation and to ensure the stability of the position of the pipes during use, avoiding unnecessary displacement or loosening. The anti-slip sleeve 13 is used to increase the friction between the hand and the locking block 205, so that the operator can rotate the locking block 205 more stably. The rubber pad 14 plays a role in stabilizing and fixing.

[0044] Reference Figure 2 and Figure 5 Sealing gaskets 11 are provided on adjacent sides of the outer walls of the two protective layers 10. Sealing gaskets 11 are used to prevent external water, air, dust and substances from entering the pipe. Identification lines 12 are provided on the outer wall of the anti-corrosion layer 9. Identification lines 12 can provide clear identification for construction or maintenance personnel, which helps to carry out construction, installation and subsequent maintenance management correctly.

[0045] Specifically, the sealing gasket 11 is used to prevent external water, air, dust and substances from entering the pipe, and the marking line 12 can provide clear markings for construction or maintenance personnel, which helps to carry out construction, installation and subsequent maintenance management correctly.

[0046] Working principle: When the HDPE silicon core pipe is subjected to external force, the pressure-resistant outer pipe 8 first bears the pressure and transmits the force to the telescopic rod 6. The telescopic rod 6 retracts inward to compress the spring 7. The spring 7 generates a reverse elastic force to offset part of the pressure. At the same time, the buffer column 5 and the buffer foam 4 absorb the impact energy through their own deformation. The buffer layer 3 further buffers and disperses the pressure. Through the synergistic effect of multiple buffer structures, the impact of external force on the inner pipe 1 and the internal cables is effectively reduced, protecting the internal silicon core layer and cables, so that they can still maintain good performance and integrity under greater pressure.

[0047] Place the pressure-resistant outer tube 8 onto the lower clamp 201, rotate the upper clamp 202, and the connecting block 204 of the upper clamp 202 rotates within the connecting block 203 of the lower clamp 201 to close it. Rotate the locking block 205 in front of the lower clamp 201 to engage with the locking groove 207 on the fixing block 206 in front of the upper clamp 202, thereby locking the upper clamp 202 and the lower clamp 201, thus tightly clamping the two pressure-resistant outer tubes 8, achieving a stable fixation of the pressure-resistant outer tubes 8, ensuring that the position of the pipe is stable during use and will not easily shift or loosen.
