Description

Technical Field

[0001] This utility model relates to the technical field of steel-plastic composite pipe fittings, and in particular to a steel-plastic composite pipe fitting with anti-slip function. Background Technology

[0002] Steel is an iron material, and plastic refers to plastic. The plastic in steel-plastic composite pipes is generally high-density polyethylene. Steel-plastic composite pipes are a new type of composite pipe material. Steel-plastic composite pipes have a higher pressure resistance than ordinary plastic pipes and are easier to install and construct. Therefore, they are increasingly widely used in engineering projects and can be used for oil and natural gas transportation, mining pipes, drinking water pipes, drainage pipes, etc. However, the steel-plastic composite pipe fittings currently in use can cause impact on the inner wall of the steel-plastic composite pipe fitting when the fluid passes through bends. When the impact is too large, it can cause the inner wall of the steel-plastic composite pipe fitting to crack. Utility Model Content

[0003] The main purpose of this utility model is to provide a steel-plastic composite pipe fitting with anti-slip function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A steel-plastic composite pipe fitting with anti-slip function includes a steel-plastic composite pipe outer layer, an inner steel-plastic composite pipe inner layer on the inner wall of the outer layer, anti-slip reinforcing ribs on the outer surface of the outer layer, and a buffer structure on the inner wall of the inner layer. The buffer structure includes a mounting plate, a first shaft, a rectangular buffer plate, a first mounting seat, a second shaft, a rectangular telescopic rod, a rectangular sliding hole, a rectangular slider, a rectangular column, a rectangular sliding groove, a return spring, a third shaft, and a second mounting seat.

[0005] In a further preferred embodiment, an installation plate is installed on the inner wall of the outer layer of the steel-plastic composite pipe near one end, and a first shaft is rotatably mounted on the installation plate via a bearing, with a rectangular buffer plate fixedly installed on the outer surface of the first shaft.

[0006] More preferably, a mounting base is installed at the lower end of the rectangular buffer plate near the other end, and a second shaft is rotatably mounted on the first mounting base via a bearing, and a rectangular telescopic rod is fixedly mounted on the outer surface of the second shaft.

[0007] In a further preferred embodiment, a second mounting base is installed on the inner wall of the inner layer of the steel-plastic composite pipe near the other end. A third shaft is rotatably mounted on the second mounting base via a bearing, and a rectangular column is fixedly mounted on the third shaft.

[0008] More preferably, the upper end of the rectangular column is provided with a rectangular sliding hole, a rectangular telescopic rod is slidably installed in the rectangular sliding hole, and the lower end of the rectangular sliding hole is provided with a rectangular sliding groove.

[0009] More preferably, a rectangular slider is slidably installed in the rectangular groove, a rectangular slider is installed at the lower end of the rectangular telescopic rod, and a return spring is connected to the bottom of the rectangular groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the buffer structure allows the fluid to move downwards at the bend of the inner layer of the steel-plastic composite pipe, thereby causing the rectangular buffer plate to slide downwards. This causes the rectangular telescopic rod installed at the lower end to slide downwards in the rectangular sliding hole, allowing the rectangular slider to slide in the rectangular sliding groove and compress the return spring. The deformation of the return spring can absorb the impact force to a certain extent. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Participation Figure 1-3As shown, a steel-plastic composite pipe fitting with anti-slip function includes an outer layer 1 of steel-plastic composite pipe, an inner layer 3 of steel-plastic composite pipe on the inner wall of the outer layer 1, anti-slip reinforcing ribs 2 on the outer surface of the outer layer 1, and a buffer structure 4 on the inner wall of the inner layer 3. The buffer structure 4 includes a mounting plate 401, a first shaft 402, a rectangular buffer plate 403, a first mounting seat 404, a second shaft 405, a rectangular telescopic rod 406, a rectangular sliding hole 407, a rectangular slider 408, a rectangular column 409, a rectangular sliding groove 410, a return spring 411, a third shaft 412, and a second mounting seat 413.

[0015] Specifically, the anti-slip reinforcing ribs 2 on the outer surface of the outer layer 1 of the steel-plastic composite pipe can increase the bonding between the pipe and the soil when large-diameter pipes are buried underground, making the pipes less prone to displacement.

[0016] Participation Figure 2-3 As shown, an installation plate 401 is installed on the inner wall of the outer layer 1 of the steel-plastic composite pipe near one end. A first shaft 402 is rotatably installed on the installation plate 401 via a bearing. A rectangular buffer plate 403 is fixedly installed on the outer surface of the first shaft 402. A first mounting seat 404 is installed at the lower end of the rectangular buffer plate 403 near the other end. A second shaft 405 is rotatably installed on the first mounting seat 404 via a bearing. A rectangular telescopic rod 406 is fixedly installed on the outer surface of the second shaft 405.

[0017] Specifically, a first shaft 402 is rotatably mounted on the mounting plate 401 via a bearing, and a rectangular buffer plate 403 is fixedly mounted on the outer surface of the first shaft 402. When the fluid passes through the bend of the inner layer 3 of the steel-plastic composite pipe, it impacts the rectangular buffer plate 403, causing one end of the rectangular buffer plate 403 to drive the first shaft 402 to rotate on the mounting plate 401. This causes the rectangular buffer plate 403 to rotate downwards around the first shaft 402 as the center, thereby causing the first mounting seat 404 mounted at the lower end of the rectangular buffer plate 403 to move downwards.

[0018] Participation Figure 2-3 As shown, a second mounting base 413 is installed on the inner wall of the inner layer 3 of the steel-plastic composite pipe near the other end. A third shaft 412 is rotatably mounted on the second mounting base 413 via a bearing. A rectangular column 409 is fixedly mounted on the third shaft 412. A rectangular sliding hole 407 is opened at the upper end of the rectangular column 409. A rectangular telescopic rod 406 is slidably installed in the rectangular sliding hole 407. A rectangular sliding groove 410 is opened at the lower end of the rectangular sliding hole 407. A rectangular slider 408 is slidably installed in the rectangular sliding groove 410. A rectangular slider 408 is installed at the lower end of the rectangular telescopic rod 406. A return spring 411 is connected to the bottom of the rectangular sliding groove 410.

[0019] Specifically, by rotating the third shaft 412 on the second mounting base 413 via a bearing, and fixing the rectangular column 409 on the third shaft 412, when the first mounting base 404 moves downward, the upper end of the rectangular telescopic rod 406 drives the second shaft 405 to rotate on the first mounting base 404, and the lower end of the rectangular column 409 drives the third shaft 412 to rotate on the second mounting base 413. At the same time, the rectangular telescopic rod 406 slides downward in the rectangular sliding hole 407, and the rectangular slider 408 installed at the lower end of the rectangular telescopic rod 406 slides downward in the rectangular sliding groove 410, and squeezes the return spring 411. The deformation of the return spring 411 can absorb the impact force to a certain extent.

[0020] It should be noted that this utility model is a steel-plastic composite pipe fitting with anti-slip function. When the fluid passes through the bend of the inner layer 3 of the steel-plastic composite pipe, it will impact the rectangular buffer plate 403, causing one end of the rectangular buffer plate 403 to drive the first shaft 402 to rotate on the mounting plate 401, causing the rectangular buffer plate 403 to rotate downward around the first shaft 402 as the center, thereby causing the first mounting seat 404 installed at the lower end of the rectangular buffer plate 403 to move downward, causing the upper end of the rectangular telescopic rod 406 to drive the second shaft 405 to rotate on the first mounting seat 404, causing the lower end of the rectangular column 409 to drive the third shaft 412 to rotate on the second mounting seat 413, and at the same time causing the rectangular telescopic rod 406 to slide downward in the rectangular sliding hole 407, causing the rectangular slider 408 installed at the lower end of the rectangular telescopic rod 406 to slide downward in the rectangular sliding groove 410, and squeezing the return spring 411. The deformation of the return spring 411 can absorb the impact force to a certain extent.
