Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, and in particular to a shock-resistant PE pipe. Background Technology

[0002] PE pipe, also known as polyethylene pipe, is made primarily of polyethylene resin, a polymer compound formed by the polymerization of ethylene monomers. A search revealed that patent application number 201922301800.8 discloses a PE pipe comprising a PE layer, expansion joints spaced between the PE layers, a diameter reduction section between the expansion joints, a flame-retardant layer on the outside of the PE layer, and an anti-corrosion layer on the outside of the flame-retardant layer. It features a simple structure, reasonable design, and long service life.

[0003] However, existing PE pipes have poor seismic resistance and are prone to deformation. Moreover, the splicing operation of PE pipes is cumbersome and has low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shock-resistant PE pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-vibration PE pipe includes two rubber mating sleeves installed sequentially at two ends of the PE pipe body. The PE pipe body is provided with equally spaced support components. Both ends of the PE pipe body are provided with centering clamping components. The support components include support seats and rubber shock-absorbing pads symmetrically bonded to the bottom outer wall of the support seats.

[0007] As a preferred technical solution of this utility model, the PE pipe body includes an inner pipe, an outer pipe, and a shock-absorbing sponge filled between the inner pipe and the outer pipe.

[0008] As a preferred technical solution of this utility model, the centering clamping assembly includes a hollow component, which is fixedly connected to the outer wall of the PE pipe body. A double-ended screw is rotatably installed inside the hollow component. A connecting strip is threaded to each of the two opposite threaded ends of the double-ended screw. A clamping plate is fixedly connected to the outer wall of the bottom end of each of the two connecting strips, and the two clamping plates are symmetrically distributed.

[0009] As a preferred technical solution of this utility model, the two clamping plates have a C-shaped structure on one adjacent side, and the two clamping plates have a contact with the outer wall surface of the rubber mating sleeve on one adjacent side.

[0010] As a preferred technical solution of this utility model, the hollow component is provided with a sliding opening, and the outer walls of the two connecting strips are slidably connected to the inner wall of the sliding opening.

[0011] As a preferred technical solution of this utility model, one end of the double-ended screw passes through one side of the hollow part and is fixedly connected to a knob, and the external thread of the double-ended screw 6 is connected to a locking nut 11.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When the PE pipe is in a vibrating environment, this utility model can effectively reduce the vibration inside the PE pipe by filling the space between the inner and outer pipes with shock-absorbing sponge. In addition, multiple support seats provide stable support for the PE pipe, preventing it from deforming due to excessive stress. Furthermore, the rubber shock-absorbing pads at the bottom of the support seats can further improve the seismic performance of the PE pipe.

[0014] 2. When PE pipes are being joined, this utility model utilizes rubber coupling sleeves at both ends of the PE pipe and two centering clamping components to connect the PE pipes to the rubber coupling sleeves. Then, by controlling the rotation of the double-ended screw with a knob, and under the limiting position of the sliding port, the two connecting strips threaded to the double-ended screw drive the two clamping plates to clamp the joint area of ​​the two PE pipes towards the center. After clamping, the rubber coupling sleeves effectively seal the joint area of ​​the two PE pipes, thus facilitating the jointing operation of the two PE pipes. The jointing operation is simpler and faster, effectively improving the jointing efficiency between PE pipes. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-3 A shock-resistant PE pipe, comprising two rubber mating sleeves 4 installed sequentially at two ends of the PE pipe body 1;

[0022] In this embodiment, the PE pipe body 1 is provided with equally spaced support components, the support components include support base 2 and rubber shock-absorbing pads 3 symmetrically bonded to the bottom outer wall of support base 2;

[0023] In this embodiment, the PE pipe body 1 includes an inner pipe 101, an outer pipe 102, and a shock-absorbing sponge 103 filled between the inner pipe 101 and the outer pipe 102;

[0024] This embodiment is implemented in a PE pipe in a vibrating environment. First, by filling the space between the inner pipe 101 and the outer pipe 102 with damping sponge 103, the vibration inside the PE pipe can be effectively reduced. Second, the PE pipe is stably supported by multiple support seats 2 to prevent it from deforming due to excessive force. Furthermore, the rubber damping pads 3 at the bottom of the support seats 2 can further improve the seismic performance of the PE pipe.

[0025] Example 2, refer to Figure 1 and Figure 4 This embodiment is an optimization based on embodiment 1. Specifically, centering clamping components are provided at both ends of the PE pipe body 1.

[0026] In this embodiment, the centering clamping assembly includes a hollow part 5, which is fixedly connected to the outer wall of the PE pipe body 1. A double-ended screw 6 is rotatably installed inside the hollow part 5. A connecting strip 7 is threaded to each of the two opposite threaded ends of the double-ended screw 6. A clamping plate 8 is fixedly connected to the outer wall of the bottom end of each of the two connecting strips 7. The two clamping plates 8 are symmetrically distributed.

[0027] Furthermore, the two clamping plates 8 have a C-shaped structure on one adjacent side, and the two clamping plates 8 have a contact with the outer wall surface of the rubber mating sleeve 4 on one adjacent side. This design makes it easier for the two clamping plates 8 to fit and squeeze the rubber mating sleeve 4 better.

[0028] Furthermore, a sliding opening 9 is provided on the hollow part 5, and the outer walls of the two connecting strips 7 are slidably connected to the inner wall of the sliding opening 9. The movement of the two connecting strips 7 can be limited through the sliding opening 9 to ensure the stability of the linear movement of the two connecting strips 7.

[0029] Furthermore, one end of the double-ended screw 6 passes through one side of the hollow part 5 and is fixedly connected to a knob 10. The knob 10 facilitates manual control of the rotation of the double-ended screw 6. The external thread of the double-ended screw 6 is connected to a locking nut 11. The locking effect of the locking nut 11 can prevent the two clamping plates 8 from pushing the double-ended screw 6 to rotate under the action of external force.

[0030] This embodiment is used in the scenario of PE pipe docking. The PE pipes to be docked are connected to the rubber docking sleeve 4. Then, the double-ended screw 6 is rotated by the knob 10. Then, under the limit of the sliding port 9, the two connecting strips 7 threaded to the double-ended screw 6 will drive the two clamping plates 8 to clamp the docking area of ​​the two PE pipes towards the center. After clamping, the rubber docking sleeve 4 can effectively seal the docking area of ​​the two PE pipes. In this way, the setting of the centering clamping component can facilitate the docking operation of the two PE pipes, making the docking operation simpler and faster, and effectively improving the docking efficiency between PE pipes.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
