Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a connection structure of a water outlet pipe of a faucet. Background Art

[0002] In the traditional faucet manufacturing industry, the connection process between the outlet pipe and the main pipe has always been a technical challenge. Although the welding connection method commonly used in the past can achieve a relatively stable structural connection, the problems it brings cannot be ignored. The 90° welded joint not only increases the difficulty of polishing, making the surface treatment work extremely cumbersome and costly, but may also cause defects in the aesthetics and durability of the final product. In addition, the heat-affected zone generated during the welding process may have an adverse effect on the material properties, and the welding parts are prone to become risk points for corrosion and leakage in future use.

[0003] As consumers' requirements for the quality of household products continue to improve, and the trend of environmental protection and sustainable development is promoted, traditional welding connection technology can no longer meet the market's demand for higher standards for faucet products. Therefore, it is particularly important to develop a new connection technology that can ensure connection strength and sealing, simplify production processes, reduce costs, and facilitate installation and maintenance.

[0004] Under this background, the present invention proposes an innovative faucet water outlet pipe connection structure. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a connection structure for a water outlet pipe of a faucet.

[0006] The technical solution adopted by the utility model is: a connection structure of a faucet water outlet pipe, comprising a main body and a water outlet pipe, wherein the side of the main body is provided with an outlet, and further comprises a connecting pipe fixedly connected to the outlet, a hollow screw member sleeved in the connecting pipe, and a connecting screw ring fixed in the water outlet pipe, wherein a pressed step is provided in the connecting pipe and pressed against the screw head of the hollow screw member, and an internal screw hole is provided in the connecting screw ring and is threadedly connected to the above-mentioned hollow screw member.

[0007] Furthermore, the connecting pipe is laser welded to the outlet.

[0008] Furthermore, a sealing groove is provided on the pipe body of the connecting pipe, and a sealing ring is provided in the sealing groove.

[0009] Furthermore, the end of the connecting pipe located at the compressed step is provided with a rounded corner.

[0010] Furthermore, a welding step is provided in the water outlet pipe, and the connecting screw ring is laser welded to the welding step.

[0011] The beneficial effects of the utility model are:

[0012] 1. Simplify the production process and reduce costs: The combined structure of the connecting pipe, hollow screw and connecting screw ring adopted in this application avoids the welding process between the main body and the outlet pipe, greatly simplifying the production process. There is no need for complex welding operations and subsequent high-cost polishing treatment, which significantly reduces manufacturing costs and improves production efficiency.

[0013] 2. Improve product quality and aesthetics: Through non-welding connection, this design effectively solves the problem of difficult polishing of welded joints, ensuring the smoothness and aesthetics of the joints of the faucet parts. The overall appearance of the product is more unified and harmonious, meeting the requirements of modern consumers for high-value household products.

[0014] 3. Easy to install and maintain: The modular connection structure makes the installation process easier and faster. Users or technicians can complete the assembly or replacement without professional welding tools. The main pipe and the outlet pipe can be replaced separately, which greatly reduces the maintenance cost and difficulty.

[0015] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
