Description

Technical Field

[0001] This utility model relates to the field of steel wire mesh reinforced composite pipe technology, specifically a steel wire mesh reinforced composite pipe that is easy to splice. Background Technology

[0002] Steel wire mesh reinforced plastic (polyethylene) composite pipe uses a high-strength copper-plated steel wire spirally wound into a mesh structure as reinforcement, high-density polyethylene (HDPE) as the matrix, and high-performance HDPE modified bonding resin. The final composite molding is achieved through continuous, multi-stage extrusion on a production line. It is widely used in long-distance buried water supply, gas supply, metal ore powder, and other special corrosive fluid pipeline systems, and is currently the preferred pipe material in China for replacing traditional pipes such as steel pipes. Steel wire mesh reinforced plastic (polyethylene) composite pipes are connected using two methods: electrofusion welding and flange connection.

[0003] For example, utility model patent CN215568797U discloses a high-strength, high-compression-resistance steel wire mesh skeleton composite pipe, comprising two pipe bodies. Each pipe body has an external compression-resistant mechanism. Mounting plates are fixedly installed on the exterior of both pipe bodies. Each mounting plate has a disassembly / assembly mechanism, including a clamping plate. The clamping plate is fixedly installed on the right side of the left mounting plate, with one end penetrating and extending into the interior of the right mounting plate. Fixing chambers are fixedly installed at the top and bottom of the right mounting plate. Two limiting sleeves are fixedly installed on opposite sides of the inner wall of each fixing chamber. A first spring is fixedly installed on opposite sides of the inner wall of each limiting sleeve. This high-strength, compressive-resistant steel wire mesh reinforced composite pipe features a disassembly and assembly mechanism, facilitating quick installation and disassembly while improving installation stability. This significantly enhances efficiency and user convenience. However, the mechanism transmits external vibrations to the connecting pipes, causing the screw to reverse. This displacement of the screw leads to the displacement of the sleeve plate, indirectly causing the positioning plate to move away from the clamping plate. Consequently, the two pipes may detach due to separation at the disassembly and assembly mechanism, reducing its stability during pipe use. Therefore, we propose a steel wire mesh reinforced composite pipe that is easy to splice. Utility Model Content

[0024] Please see Figure 1-Figure 5 This utility model provides a technical solution: a steel wire mesh skeleton composite pipe that is easy to splice, including a composite pipe body 1. Two symmetrically distributed L-shaped insert plates 4 are fixedly connected to the front end of the outer periphery of the composite pipe body 1.

The second spring 614 is located outside the rotating shaft 611. The inner end face of the claw 612 is slidably connected to multiple circumferentially distributed ratchet grooves 604 on the outer periphery of the rotating ratchet 603. A rotating rod 602 is fixedly connected to the lower end face of the rotating ratchet 603. A threaded groove is provided on the outer periphery of the rotating rod 602. A placement box 601 is rotatably connected to the outer surface of the rotating rod 602 through a bearing. The lower end face of the placement box 601 is fixedly connected to the composite tube body 1. A movable sleeve 605 is threadedly connected to the outer surface of the rotating rod 602. A movable plate 606 is fixedly connected to the lower end of the movable sleeve 605. A pin 607 is provided at the lower end of the movable plate 606.

[0025] In this embodiment, a guide rod 608 is slidably connected to the surface of the movable plate 606 and the guide rod 608 passes through the movable plate 606. The guide rod 608 is located on the side of the movable sleeve 605 near the placement box 601, and the upper end face of the guide rod 608 is fixedly connected to the placement box 601.

[0026] Specifically, the guide rod 608 guides the moving plate 606 during its movement, thereby improving the stability of the moving plate 606.

[0027] In this embodiment, a first spring 610 is fixedly connected to the upper end of the movable plate 606, and a placement box 601 is fixedly connected to the upper end of the first spring 610. The first spring 610 is located on the outside of the guide rod 608.

[0028] Specifically, the first spring 610 can perform a pre-tensioning action on the movable plate 606.

[0029] In this embodiment, a sealing groove 2 is provided at the front end of the composite pipe body 1, and a sealing ring 3 is fixedly connected to the end of the composite pipe body 1 away from the sealing groove 2.

[0030] Specifically, the sealing groove 2 and the fixedly connected sealing ring 3 at the front end of the composite pipe body 1 effectively improve the sealing performance of the pipe connection, prevent liquid or gas leakage, and ensure the normal operation of the pipeline system.

[0031] In this embodiment, the outer surface of the rotating shaft 611 is rotatably connected to the placement box 601 via a bearing, and the lower end of the second spring 614 is fixedly connected to the placement box 601.

[0032] Specifically, ensure that the rotating shaft 611 does not interfere with the placement box 601.

[0033] In this embodiment, a limiting post 615 is fixedly connected to the inner side of the lower end of the pawl 612, and an arc-shaped groove 616 is provided on the right side of the upper end of the placement box 601. The arc-shaped groove 616 is slidably connected to the outer surface of the limiting post 615.

[0034] Specifically, the design of the limiting post 615 and the arc groove 616 enables the angle control of the pawl 612 during rotation.

[0035] In this embodiment, a limiting plate 609 is fixedly connected to the lower end of the guide rod 608, and the outer diameter of the limiting plate 609 is larger than the outer diameter of the guide rod 608.

[0036] Specifically, the lower limit of the movement of the movable plate 606 can be controlled by setting the limit plate 609.

[0037] In this embodiment, an operating handle 613 is provided on the upper end face of the pawl 612, and the operating handle 613 is L-shaped.

[0038] Specifically, by providing an operating handle 613, when it is necessary to rotate the ratchet 603 counterclockwise, it is convenient to perform work on the pawl 612, so that the rotating rod 602 can be directly worked by rotating the ratchet 603.

[0039] Working principle: Align the L-shaped insert plate 4 of one composite pipe body 1 with the placement box 601 of the quick-release locking assembly 6 on another composite pipe body 1. At this time, the L-shaped insert plate 4 abuts against the inner wall of the placement box 601. Next, rotate the ratchet 603 clockwise. The ratchet 603 drives the rotating rod 602 to rotate clockwise, which in turn drives the moving sleeve 605 to move downward. The moving sleeve 605 drives the moving plate 606 to move downward, which in turn drives the insertion post 607 to move downward. During the downward movement, the insertion post 607 slowly inserts into the insertion hole 5. During the rotation of the ratchet 603, the pawl 612 contacts the ratchet 603. The pawl 612 drives the rotating shaft 611 to reciprocate in a counterclockwise direction at a certain angle. The limiting post 615 reciprocates in the arc groove 616. At this time, the pawl 612 will be engaged in the appropriate position of the ratchet groove 604, realizing the lock. When it is necessary to disassemble the two composite pipe bodies 1, the ratchet 603 can be rotated clockwise at a small angle first (at this time, the pawl 612 can be disengaged from the ratchet groove 604). Next, the pawl 612 can be rotated counterclockwise to the maximum angle through the operating handle 613. At this time, the limiting post 615 is at the upper limit position of the arc groove 616. Then, the ratchet 603 can be rotated counterclockwise. The ratchet 603 drives the rotating rod 602 to rotate counterclockwise, which in turn drives the moving sleeve 605 to move upward. The moving sleeve 605 indirectly drives the insertion post 607 to slowly disengage from the insertion hole 5. This utility model realizes that the ratchet and pawl 612 locking mechanism ensures that the composite pipe has stable connection strength after splicing, prevents external vibration from affecting the rotating ratchet 603, can withstand greater internal pressure and external force, and ensures the safety and stability of the pipeline system.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
