Description

Technical Field

[0001] This utility model relates to a component for pipe connection, specifically a double anti-detachment component for pipes, belonging to the technical field of pipe material fittings. Background Technology

[0002] Common pipe connection methods include sleeve connections and threaded connections. To ensure tightness and reliability of the connection and effectively prevent leakage, common methods include using sealing rings and adding anti-detachment components.

[0003] For example, Chinese utility model patent CN223411709U discloses a pipe joint in which anti-detachment structures are formed by buckles on the first straight section, the flared section, and the second straight section, directly on the outer side of the inner core and the inner side of the outer sleeve of the pipe. Chinese utility model patent application CN120868280A discloses a multi-layer high-temperature wear-resistant composite pipe with an anti-detachment linkage system composed of an annular mounting ring, gears, and hinged connecting rods. It can be seen that existing anti-detachment structures suffer from problems such as easy damage to rigid structural connections or complex structures. Utility Model Content

[0004] The purpose of this utility model is to provide a soft, simple, and widely applicable double anti-detachment component for pipelines.

[0005] This utility model is implemented as follows:

[0006] A double anti-detachment component for pipelines includes a rubber strip with long and short columns spaced apart on it.

[0007] A further step is:

[0008] The rubber strip is a long strip with a rectangular cross-section, which provides strong shear resistance for the connection between the long and short columns, ensuring that the components are not pulled into the flared inner diameter when under stress, thus preventing the anti-detachment function from failing.

[0009] A further step is:

[0010] The rubber strip has a disassembly ramp on one end of the long column and the other end of the short column to facilitate installation and disassembly.

[0011] A further step is:

[0012] The tops of the long and short columns are rounded for easy installation.

[0013] A further step is:

[0014] The number of both long and short columns is at least two, and more can be set according to actual needs to achieve better sealing and anti-detachment effects.

[0015] This utility model is used to install between the connection between a straight pipe and the outer flared end. The long column increases the stability of the straight pipe within the inner diameter of the flared end, and the short column contacts the sealing ring to further restrict the movement of the straight pipe and ensure that the sealing ring is limited and fixed, preventing it from falling off and causing leakage.

[0016] This utility model has a simple structure, is easy to install, and has a dual anti-fall-off effect, making it a promising application. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 As shown, this embodiment provides a dual anti-detachment component for pipelines, including a rubber strip 1, with long posts 2 and short posts 3 spaced apart on the rubber strip. The rubber strip has a certain degree of rigidity to facilitate a tight fit with the curved surface of the pipeline.

[0024] The rubber strip 1 is a long strip with a rectangular cross-section, which provides strong shear resistance for the connection between the long and short columns, ensuring that the components are not pulled into the flared inner diameter when under stress, thus preventing the anti-detachment function from failing.

[0025] The rubber strip 1 has a disassembly ramp 4 at one end of the long column and the short column side, which facilitates installation and disassembly.

[0026] The tops of the long column 2 and the short column 3 are rounded for easy installation.

[0027] As a specific embodiment of this utility model, the utility model provides a specific application of the double anti-detachment component 5 for pipelines, as shown in the attached figure. Figure 2-5 As shown.

[0028] From the appendix Figure 2 , 3 It can be seen that the double anti-detachment component 5 of the pipeline is installed between the connection between the straight pipe 6 and the outer flared end 7. The straight pipe 6 has an inner diameter of 63, and a large outer diameter of 61 and a small outer diameter of 62 on the outer wall of the straight pipe. The flared end 7 has an inner diameter of 73, and a large outer diameter of 71 and a small outer diameter of 72 on the outer wall of the flared end.

[0029] As attached Figure 4 As shown, the long column 2 of the double anti-detachment component 5 of the pipeline is installed between the outer large diameter 61 and the outer small diameter 62 of the straight pipe to achieve the first layer of anti-detachment fixation and ensure that the straight pipe does not move relative to the inner diameter of the flared opening.

[0030] As attached Figure 5 As shown, the small column 3 of the double anti-detachment component 5 of the pipeline can break under overload when the relative movement between the straight pipe and the flared end is too large due to thermal expansion and contraction of the pipeline or geological subsidence. This provides space for the relative movement of the pipeline. At this time, the small column 3 comes into contact with the sealing ring 8 to form a second layer of anti-detachment.

[0031] Under the constraint of the double anti-detachment component 5 provided in this embodiment, the sealing ring 8 in the straight pipe is always within the inner diameter 73 of the flared opening, and the liquid in the pipe will never leak out of the pipe.

[0032] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
