[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions: an EPTU steady drain pipe joint includes an elastic rubber ring, an anti-dropping buckle, a connecting groove, and a connecting sleeve. Connecting grooves are arranged on the inner walls at both ends inside the connecting sleeve, and the connecting grooves are clamped and matched with the inner pipe. An anti-dropping buckle is also arranged between the connecting grooves and the inner pipe, and the anti-dropping buckle is matched with a retaining hoop. An elastic rubber ring is arranged at the matching part between the connecting sleeve and the inner pipe.

[0005] Preferably, the upper end of the connecting sleeve is circular, and the lower end is flat, and the connecting sleeve is matched with the shape of the EPTU steady drain pipe.

[0006] Preferably, the anti-dropping buckle is a retaining piece.

[0015] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation manners.

[0016] Referring to Figures 1-5 , the following technical solutions are adopted in this detailed implementation manner: A pipe joint for an EPTU steady-state drainage pipe includes an elastic rubber ring 1, an anti-disengagement buckle 2, a connection slot 3 and a connection sleeve 4. Connection slots 3 are provided on the inner walls at both ends inside the connection sleeve 4. The connection slots 3 are in snap-fit with the inner pipe 5. An anti-disengagement buckle 2 is also provided between the connection slots 3 and the inner pipe 5. The anti-disengagement buckle 2 cooperates with a backstop hoop 6. An elastic rubber ring 1 is provided at the mating part of the connection sleeve 4 and the inner pipe 5.

[0017] The upper end of the connection sleeve 4 is circular, and the lower end is flat. The connection sleeve 4 is shaped to match the EPTU steady-state drainage pipe.

[0018] The anti-disengagement buckle 2 is a backstop piece.

[0019] The pipe joint of this detailed implementation manner is applied to an EPTU steady-state drainage pipe. The upper end is circular and the lower end is parallel. Its shape matches that of the EPTU steady-state drainage pipe, and it has good mechanical properties and installation stability..

[0020] The joint of this detailed implementation manner is composed of an elastic rubber ring, an anti-disengagement buckle (backstop piece), a connection slot and a connection sleeve. By using the elastic rubber ring, the elasticity and sealing property of the rubber can be utilized to ensure close contact at the joint, effectively preventing water leakage or seepage. The design of the anti-disengagement buckle (backstop piece) can ensure that the joint will not easily become loose when subjected to pulling or vibration, enhancing the safety and stability of the connection. The combined use of the connection slot and the connection sleeve simplifies the installation process, making the connection between the pipe and the joint more convenient and rapid, and at the same time can provide sufficient mechanical strength and pressure resistance.

[0021] This detailed implementation manner has a simple structure, which not only reduces the manufacturing cost but also reduces the labor cost during installation and maintenance. At the same time, due to the use of rubber materials with good elasticity and aging resistance, the service life of the joint is improved, and the frequency of pipe maintenance caused by joint aging or damage is reduced.

[0022] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will also have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
