[0003] A connecting device for HDPE same-layer siphon drainage pipe fittings is disclosed in Publication No. CN208670403U. The device comprises a pipe body, a connecting buckle and a screw. The connecting ports of the pipe body are fixedly connected through the connecting buckle. The connecting ports of the pipe body are provided with a connecting positive pole. The connecting ports at both ends of the connecting buckle are provided with a connecting negative pole. The connecting positive pole and the connecting negative pole are both composed of a groove ring and a protrusion ring. The diameter of the groove ring of the connecting positive pole is greater than that of the protrusion ring. The diameter of the protrusion ring of the connecting negative pole is greater than that of the groove ring. The groove ring and the protrusion ring are adjacently arranged.

[0006] The technical scheme adopted by the application is as follows: a connecting device for HDPE same-layer siphon drainage pipe fittings comprises a connecting main body. A platform is arranged on the upper surface of the connecting main body and provided with a connecting plate. A plurality of threaded holes are arranged in the upper surface of the connecting plate. A connecting block is fixedly connected to the upper surface of the connecting plate. An oil injection nozzle cover plate is arranged at one end of the connecting block relative to the connecting plate.

[0012] In a preferred embodiment, one side of the connecting main body is provided with a socket.

[0013] By adopting the technical scheme, the main use of the sealing rubber ring is to fill the gap between the connecting device and the pipeline, and by virtue of its good elasticity and sealing performance, it can effectively prevent water flow from leaking through the connection after the pipe and pipe fitting are connected, and plays a crucial role in the anti-leakage work of the entire drainage system.

[0020] In a preferred embodiment, the connecting body is fixedly connected with a reinforcing rib on one side.

[0021] By adopting the technical scheme, the reinforcing rib is used to enhance the overall structural strength of the drainage pipe and fitting connecting device, can prevent the connecting device from deforming, damaging and the like, ensure the stability of the structure, maintain the correct connection relationship between the components, and further ensure that the entire drainage system can operate normally for a long time, prolonging the service life of the device.

[0022] In summary, due to the adoption of the above technical scheme, the beneficial effects of the present application are:

When installing the pipe fittings, sometimes it may be difficult to insert, such as the friction between the pipe and the fitting is large, which makes it difficult to butt joint. Through the detachable lubricating oil injection nozzle structure, an appropriate amount of lubricant can be injected into the connecting part, effectively reducing the friction, so that the pipe can be more smoothly inserted into the fitting, thereby improving the convenience of installation, saving installation time and labor cost. During the long-term operation of the drainage system, friction will continuously occur between the pipes and fittings, especially under conditions such as water pressure changes and water impact, which may exacerbate the friction and cause parts to wear. Regularly injecting lubricant through the lubricating oil injection nozzle structure can continuously maintain the good lubrication state of the connecting part, reduce wear and tear, prolong the overall service life of the pipe fitting connecting device, and reduce replacement cost.

[0034] Referring to Figure 4 , the socket 8 is arranged on one side of the connecting body 1. The socket 8 provides a positioning basis for the connection between the pipes and fittings, and cooperates with the sealing rubber ring 9 to enhance the sealing performance of the connection, prevent leakage during drainage, and is one of the key structures to ensure the normal operation of the drainage system.

[0035] Referring to Figure 4 , the sealing rubber ring 9 is arranged on one side of the socket 8 at one end of the connecting body 1.

The fixed thread groove 11 provides a threaded space for connecting the pipe and the connecting device, and by being able to butt together the fixed thread groove 11 and the water pipe threaded connection port 13, the connection of them can be more firm and stable, avoiding loosening phenomenon due to water flow impact, external force vibration and other factors during use, and ensuring long-term reliable operation of the drainage system.

[0037] With reference to Figure 4 The inner side of one end of the connecting body 1 is provided with a limiting clamping groove 12. The limiting clamping groove 12 ensures that the standard insertion depth can be achieved every time the pipe and fitting are connected, and guarantees the stability and sealing of the connection, which is an important structural detail to ensure the connection quality.

[0039] With reference to Figure 2 The side of the connecting body 1 is fixedly connected with a reinforcing rib 15. The reinforcing rib 15 is used to enhance the overall structural strength of the drainage pipe and fitting connecting device, and can prevent the connecting device from deforming, damaging and the like, ensure the stability of the structure, maintain the correct connection relationship between the components, and thus ensure that the entire drainage system can operate normally for a long time, and prolong the service life of the device.

[0040] The implementation principle of the connecting device embodiment of the HDPE same layer siphon drainage pipe and fitting of the application is:
