[0001] This utility model relates to the field of faucet technology, specifically to a welded stamped washbasin faucet. Background Technology

[0002] A faucet is a widely used appliance in daily life and work. A faucet connects to a water pipe via a base, directing water from the pipe into the faucet. The water then flows through a channel within the faucet and is directed to the spout, where it is discharged outwards. A washbasin faucet is a type of faucet used on washbasins. It's a switch above the bathroom sink used to control the flow of hot and cold water. It mainly consists of the faucet body, valve core, and spout. The valve core controls the faucet's operation, the faucet body directs the water flow, and the spout discharges the water. It is convenient, simple to use, and highly adaptable.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: existing basin faucets are formed by casting, and during processing, they often need to be used with sand cores to make the interior of the outer shell hollow. After processing, the sand cores cannot be recycled and can only be discarded, which can easily lead to environmental pollution. At the same time, the production cost is high, and the faucet also needs to be polished and trimmed after processing, which makes the production speed slow, the process more complicated, and the yield rate low. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a welded stamped washbasin faucet with low cost, simple processing technology, and high yield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a welded stamped washbasin faucet, comprising a faucet body and a water outlet pipe on the side wall of the faucet body. The faucet body includes an outer shell cut from a pipe and a connector with a penetrating opening welded to the lower end of the outer shell.

The outer edge of the one-piece structure is welded to the lower end of the outer shell. The recessed part is provided with internal threads.

[0007] A further improvement is that the connector includes a connector body formed by cutting a pipe at the lower end of the outer shell and an upper sealing plate welded to the top edge of the connector body and formed to connect with the bottom end of the water inlet pipe. The upper sealing plate is formed by cutting a plate and the connector body is provided with internal threads.

[0008] A further improvement is that the bottom outer wall of the connector body also has a lower sealing piece, and the outer edge of the lower sealing piece is welded to the lower end of the outer shell.

[0009] A further improvement is that the connector includes a shrink tube integrally formed on the lower end of the outer shell by stamping. The outer wall of the shrink tube is provided with external threads. A sealing plate is also welded to the bottom end of the shrink tube to seal the bottom end of the shrink tube. The sealing plate has an opening. The bottom end of the water inlet pipe is welded to the sealing plate at the position of the opening.

[0010] A further improvement is that the valve core seat structure includes a valve core seat body integrally formed by stamping with its top edge welded to the top of the outer shell, and a water outlet hole integrally formed on the side wall of the valve core seat body.

Detailed Implementation

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1:

[0017] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a welded stamped washbasin faucet, including a faucet body 1 and a water outlet pipe 2 on the side wall of the faucet body 1. The faucet body 1 includes an outer shell 11 cut from a pipe fitting and a connector 12 with a penetrating opening welded to the lower end of the outer shell 11. A water inlet pipe 14 is welded to the penetrating opening of the connector 12. A valve core seat structure 15 is welded to the top of the outer shell 11. The top of the water inlet pipe 14 penetrates the bottom surface of the valve core seat structure 15 and is welded to the bottom surface of the valve core seat structure 15. 5 includes a valve core seat body 151 integrally formed by stamping and having its top edge welded to the top of the outer casing 11, and a water outlet hole 152 integrally formed on the side wall of the valve core seat body 151. The bottom surface of the valve core seat body 151 is provided with a water inlet pipe interface 153 through which the water inlet pipe 14 can pass. During the forming process, the faucet body 1 is formed first, the outer casing 11 is formed by cutting a thicker pipe, and a hole for water outlet is formed on the side wall of the outer casing 11. A thinner pipe is cut to form the water inlet pipe 14. Then, the valve core seat body 15, which includes the connector 12 and the valve core seat structure 15, is formed by stamping. 51. A water outlet hole 152 is opened on the edge of the valve core seat body 151, and an opening with the same diameter as the water inlet pipe 14 is opened on both. Then, the water inlet pipe 14 is welded to the water inlet interface 153 formed at the bottom of the valve core seat body 151 of the valve core seat structure 15. The valve core seat structure 15 is then inserted into the outer shell 11 from the top, and the connector 12 is inserted from the bottom of the outer shell 11. Then, the top of the valve core seat body 151 of the valve core seat structure 15 is welded to the top of the outer shell 11, and the edge of the connector 12 is welded to the bottom of the outer shell 11. At the same time, the water inlet is welded. The upper and lower ends of the pipe 14 are fixedly connected to the valve core seat structure 15 and the connector 12. Then, the valve core is installed on the valve core seat structure 15 to form the faucet body 1. Then, the water outlet pipe 2 is welded to the hole position of the outer shell 11 to form the faucet. The processing technology is simple, the cost is low, the forming speed is fast and the yield is high. Moreover, no sand core is needed, which reduces the pollution to the environment during the production process. When in use, the faucet is installed into the end of the external water pipe, so that the faucet can input water flow through the water inlet pipe 14 and output water flow through the water outlet pipe 2 under the control of the valve core. The connector 12 is a one-piece structure. The one-piece structure is formed by stamping and recessing into the outer shell 11. The top of the recess is provided with an opening. The recess is located at the opening and is welded to the bottom end of the water inlet pipe 14. The outer edge of the one-piece structure is welded to the lower end of the outer shell 11. The recess is provided with an internal thread 13, which is convenient for inserting into the end of the external water pipe through the recess, making the faucet installation simpler and more convenient. The internal thread 13 is used to engage with the thread on the external water pipe, making the installation more convenient and secure. A connecting ring 154 is also welded to the top surface of the valve core seat body 151. The connecting ring 154 can be integrally formed by punching after expanding the top hole of the valve core seat body 151, or it can be cut from a plate and welded to the top outer wall of the valve core seat body 151. This is beneficial for positioning the valve core seat body 151 by the edge of the connecting ring 154, preventing it from going too far down into the inner wall of the outer shell 11, and making welding simpler and more convenient.

[0018] All of the above components are made of stainless steel, which is clean, hygienic, and not prone to contamination. Example 2:

[0019] See Figure 1-2 , Figure 4 As shown, the difference between this specific embodiment and Embodiment 1 is that the valve core seat structure 15 includes a valve core seat body 151 formed by cutting a pipe fitting and having its top edge welded to the top of the outer shell 11, and a water outlet hole 152 integrally formed on the side wall of the valve core seat body 151. A sealing plate 155 is welded to the bottom surface of the valve core seat body 151. The bottom surface of the sealing plate 155 is provided with a water inlet pipe interface 153 through which the water inlet pipe 14 can pass. When forming the valve core seat structure 15, the valve core seat body 151 can be formed by cutting a pipe fitting, and a hole is drilled in its side wall to form the water outlet hole 152. At the same time, the sealing plate 155 is placed at the bottom of the valve core seat body 151, and the edge of the sealing plate 155 is welded to the bottom end of the valve core seat body 151. Then, a hole is drilled in the bottom surface of the sealing plate 155 to form the water inlet pipe interface 153. At this time, the valve core seat structure 15 can be formed. Compared with stamping, the valve core seat structure 15 formed by this method is simpler to process and has lower requirements for processing technology. Example 3:

[0020] See Figure 1-2 , Figure 5 As shown, the difference between this specific embodiment and Embodiment 1 and Embodiment 2 is that the connector 12 includes a connector body 121 formed by cutting a pipe fitting at the lower end of the outer shell 11 and an upper sealing plate 122 welded to the top edge of the connector body 121 and formed to connect with the bottom end of the water inlet pipe 14. The upper sealing plate 122 is formed by cutting a plate. The connector body 121 is provided with an internal thread 13. The connector body 121 is formed by cutting the pipe fitting, and the upper sealing plate 122 is formed by cutting the plate. The two are then welded together to form the connector 12. Compared with the connector 12 formed by stamping, the connector formed in this way does not require stamping by controlling the stamping machinery with precision instruments. The processing is simpler and more convenient for mass production. The bottom outer wall of the connector body 121 also has a lower sealing piece 123. The lower sealing piece 123 can be integrally formed by punching after expanding the hole of the connector body 121, or it can be a plate cut and welded to the bottom outer wall of the lower sealing piece 123. The outer edge of the lower sealing piece 123 is welded to the lower end of the outer shell 11, which is conducive to sealing the bottom of the outer shell 11 through the lower sealing piece 123 to prevent water leakage. Example 4:

[0021] See Figure 6 As shown, the difference between this specific embodiment and Embodiments 1, 2, and 3 is that the connecting member 12 includes a shrink tube 222 integrally formed by stamping at the lower end of the outer shell 11. The outer wall of the shrink tube 222 is provided with external threads 223. A sealing plate 224 is also welded to the bottom end of the shrink tube 222 to seal the bottom end of the shrink tube 222. The sealing plate 224 has an opening. The bottom end of the water inlet pipe 14 is welded to the sealing plate 224 at the opening. The sealing plate 224 is used to prevent water from leaking out from the lower end of the shrink tube 222. At this time, the shrink tube 222 can be directly formed by stamping and external threads 223 are formed on its outer wall, so that the bottom of the outer shell 11 does not need to be additionally assembled with separate connecting pipes and multiple sealing parts during installation. Therefore, there are fewer steps in use and installation, and it is simpler and more convenient to use.

[0022] The working principle of this utility model is as follows: During the molding process, the faucet body 1 is first formed. A thicker pipe is cut to form the outer shell 11, and a hole for water outlet is formed on the side wall of the outer shell 11. A thinner pipe is cut to form the inlet pipe 14. Then, the valve core seat body 151 of the connector 12 and valve core seat structure 15 is formed by stamping. A water outlet hole 152 is opened on the edge of the valve core seat body 151, and openings with the same diameter as the inlet pipe 14 are made on both. The inlet pipe 14 is then welded to the inlet pipe interface 153 formed at the bottom of the valve core seat body 151 of the valve core seat structure 15. The valve core seat structure 15 is then inserted into the outer shell 11 from the top, and the connector 12 is inserted from the bottom of the outer shell 11. Then... The top of the valve core seat body 151 of the valve core seat structure 15 is welded to the top of the outer shell 11, and the edge of the connector 12 is welded to the bottom of the outer shell 11. At the same time, the upper and lower ends of the water inlet pipe 14 are welded to fix it to the valve core seat structure 15 and the connector 12. Then, the valve core is installed on the valve core seat structure 15 to form the faucet body 1. Then, the water outlet pipe 2 is welded to the hole position of the outer shell 11 to form the faucet. The processing technology is simple, the cost is low, the molding speed is fast and the yield is high. Moreover, no sand core is needed, which reduces the pollution to the environment during the production process. When in use, the faucet is installed into the end of the external water pipe, so that the faucet can input water flow through the water inlet pipe 14 and output water flow through the water outlet pipe 2 under the control of the valve core.
