PE communication pipe with built-in heat dissipation pipe

Abstract

This utility model discloses a PE communication tube with a built-in heat dissipation pipe, relating to the field of PE tube technology. It includes a tube body with multiple ratchet teeth arranged in a circumferential array at one end, and a second ring fitted at the other end. Multiple locking units are arranged in a circumferential array within the second ring. Each locking unit includes a rotating shaft and a pawl. The rotating shaft is located within the second ring, and the pawl is rotatably fitted onto the rotating shaft. A reset component is provided between the pawl and the rotating shaft to drive the pawl to rotate towards the tube body axis. Each pawl and each ratchet tooth are engaged in a one-to-one engagement. An unlocking component is provided on the tube body to drive each pawl to rotate away from the tube body axis. When two tube bodies are joined together, the conical or smooth surface of the ratchet teeth pushes the pawl away, causing the pawl to rotate and lift against the force of the reset component. When the ratchet teeth reach the pawl position, the pawl rotates and resets under the action of the reset component. Due to the unidirectional nature of the ratchet teeth, pulling backward causes the pawl tip to engage more deeply into the tooth groove, achieving locking.

Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, specifically a PE communication pipe with a built-in heat dissipation pipe. Background Technology

[0002] PE pipe, or polyethylene pipe, is widely used in my country, with water supply pipes and gas pipes being its two largest application markets. Internationally, polyethylene pipe materials are classified into five grades: PE32, PE40, PE63, PE80, and PE100. Existing multi-hole PE communication pipes, also known as plum blossom pipes or honeycomb pipes, are widely used in communication cables and optical cables. This type of pipe has high utility value and a long service life.

[0003] In the existing technology, two PE pipes are usually connected by socket flexible connection or electrofusion connection. However, these two methods are time-consuming and inefficient. Furthermore, if the communication line fails and needs to be repaired and maintained, the two PE pipes are not easy to disassemble and separate, which is inconvenient for maintenance work. Utility Model Content

[0004] The purpose of this invention is to provide a PE communication tube with a built-in heat dissipation tube to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The PE communication pipe with built-in heat dissipation pipe includes a pipe body. One end of the pipe body is provided with a plurality of ratchet teeth arranged in a circumferential array, and the other end of the pipe body is fitted with a second sleeve ring. The second sleeve ring is provided with a plurality of locking units arranged in a circumferential array. Each locking unit includes a rotating shaft and a pawl. The rotating shaft is disposed in the second sleeve ring, and the pawl is rotatably sleeved on the rotating shaft. A reset component is provided between the pawl and the rotating shaft for driving the pawl to rotate in the direction of the pipe body axis. Each pawl and each ratchet tooth are engaged in a one-to-one corresponding engagement. The pipe body is provided with an unlocking component for driving each pawl to rotate in a direction away from the pipe body axis.

[0006] Furthermore, each of the reset components includes a torsion spring, and each torsion spring is sleeved with each rotating shaft in a one-to-one correspondence.

[0007] Furthermore, the unlocking component includes multiple racks, each pawl is provided with a first gear, a first collar is fixedly sleeved on the tube body, each rack is radially slidably connected to one side of the first collar in a circumferential array, and each rack meshes with each first gear in a one-to-one correspondence.

[0008] Furthermore, the first ring has multiple sliding grooves arranged in a circular array, each groove is rotatably connected to a screw, each screw is screwed to a slider, each slider is slidably connected in its respective groove, and each slider is fixedly connected to one side of each rack.

[0009] Furthermore, a face gear is vertically rotatably connected inside the first sleeve, and a second gear is coaxially fixedly connected to one end of each screw, with each second gear meshing with the face gear.

[0010] Furthermore, an arc-shaped guide groove is provided on the side of the first ring near the second ring, and a push rod is slidably connected in the guide groove. The push rod is fixedly connected to one end of the end face gear.

[0011] Compared with the prior art, the beneficial effects provided by this utility model are as follows: the two tubes of the PE communication tube with built-in heat dissipation pipe are connected to each other. The conical or smooth surface of the ratchet pushes open the pawl tip. The pawl rotates slightly and lifts up against the force of the reset component. When the ratchet reaches the pawl position, the pawl rotates and resets under the action of the reset component. The pawl tip falls into the tooth groove of the ratchet. Due to the unidirectional nature of the ratchet, pulling it backward will make the pawl tip lock deeper into the tooth groove to achieve locking. The two PE communication tubes can be automatically connected by only one plug-in action. When disassembling, the two PE communication tubes can be separated by rotating the push rod. It can be quickly connected, improves the connection efficiency, and facilitates maintenance work. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-6 The present invention provides a technical solution: a PE communication tube with a built-in heat dissipation pipe includes a tube body 1. One end of the tube body 1 has a plurality of ratchet teeth 4 arranged in a circumferential array, and the other end of the tube body 1 is fitted with a second collar 3. The second collar 3 has a plurality of locking units arranged in a circumferential array within it. Each locking unit includes a rotating shaft 7 and a pawl 5. The rotating shaft 7 is disposed within the second collar 3, and the pawl 5 is rotatably fitted onto the rotating shaft 7. A reset member is provided between the pawl 5 and the rotating shaft 7 for driving the pawl 5 to rotate toward the axis of the tube body 1. Each pawl 5 and each ratchet tooth 4 are engaged in a one-to-one locking fit. The body 1 is equipped with an unlocking component for driving each pawl 5 to rotate in a direction away from the axis of the tube body 1. Specifically, a heat dissipation pipe can be installed inside the tube body 1. Each reset component includes a torsion spring 8, and each torsion spring 8 is sleeved with each rotating shaft 7 in a one-to-one correspondence. When two tube bodies 1 are in contact, the conical or smooth surface of the ratchet 4 pushes open the pawl tip of the pawl 5. The pawl 5 rotates slightly and lifts against the force of the torsion spring 8. When the ratchet 4 reaches the position of the pawl 5, the pawl 5 rotates and resets under the action of the torsion spring 8, and the pawl tip falls into the tooth groove of the ratchet 4. Due to the unidirectional nature of the ratchet 4, pulling backward will cause the pawl tip to be inserted deeper into the tooth groove to achieve locking.

[0022] As a preferred technical solution, the unlocking component includes multiple racks 9, each pawl 5 is provided with a first gear 6, and a first ring 2 is fixedly sleeved on the tube body 1. Each rack 9 is radially slidably connected to one side of the first ring 2 in a circumferential array, and each rack 9 meshes with each first gear 6 in a one-to-one correspondence. Specifically, when the two tube bodies 1 are connected, each rack 9 does not mesh with the corresponding gear. By driving each rack 9 to move synchronously radially toward the axis of the tube body 1, each rack 9 drives the corresponding gear to rotate, pushing the tail of the pawl 5, forcing the pawl 5 to overcome the force of the torsion spring 8 and rotate and lift up, and the pawl tip disengages from the groove of the ratchet tooth 4, so that the two tube bodies 1 can be disassembled.

[0023] As a preferred technical solution, the first ring 2 has multiple grooves 10 arranged in a circular array. Each groove 10 is rotatably connected to a screw 11, and each screw 11 is screwed with a slider 12. Each slider 12 is slidably connected in each groove 10. Each slider 12 is fixedly connected to one side of each rack 9. Specifically, multiple screws 11 can be rotated simultaneously. Through the helical transmission of the screws 11, and the grooves 10 restrict the axial rotation of the corresponding sliders 12, each slider 12 drives the corresponding rack 9 to slide radially.

[0024] As a preferred technical solution, a face gear 14 is vertically rotatably connected inside the first ring 2, and a second gear 13 is coaxially fixedly connected to one end of each screw 11. Each second gear 13 meshes with the face gear 14. Specifically, an arc-shaped guide groove 16 is opened on the side of the first ring 2 near the second ring 3. A push rod 15 is slidably connected inside the guide groove 16. The push rod 15 is fixedly connected to one end of the face gear 14. By rotating the push rod 15, the face gear 14 is driven to rotate. The face gear 14 drives each second gear 13 to rotate synchronously, so that each screw 11 rotates synchronously, and each pawl 5 disengages from the ratchet 4 synchronously.

[0025] Working principle: The two PE communication tubes 1 with built-in heat dissipation pipes are connected to each other. The conical or smooth surface of the ratchet 4 pushes open the pawl tip of the pawl 5. The pawl 5 rotates slightly and lifts against the force of the torsion spring 8. When the ratchet 4 reaches the position of the pawl 5, the pawl 5 rotates back to its original position under the action of the torsion spring 8, and the pawl tip falls into the tooth groove of the ratchet 4. Due to the unidirectional nature of the ratchet 4, pulling it backward will cause the pawl tip to be locked deeper into the tooth groove. The two PE communication tubes can be automatically connected with just one insertion action. When disassembling, the push rod 15 is rotated to drive the end face gear 1. 4. Rotation: The end face gear 14 drives each second gear 13 to rotate synchronously, causing each screw 11 to rotate synchronously. Through the helical transmission of the screw 11, the slide groove 10 restricts the axial rotation of the corresponding slider 12, causing each slider 12 to drive the corresponding rack 9 to slide radially. Each rack 9 drives the corresponding gear to rotate, pushing the tail of the pawl 5, forcing the pawl 5 to overcome the force of the torsion spring 8 and rotate and lift up. The pawl tip disengages from the groove of the ratchet tooth 4, which can separate the two PE communication tubes, enabling quick connection, improving connection efficiency, and facilitating maintenance work.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
