Description

Technical Field

[0001] This invention relates to the field of sanitary ware, specifically to an economical ball joint and its processing method. Background Technology

[0002] With the rapid development of modern technology, people's demands for living standards are increasing. Nowadays, most family bathrooms are equipped with overhead shower systems to meet people's showering needs. Typically, an overhead showerhead has a ball joint (as shown in patent CN201220406255.4) installed between the water outlet panel and the shower hose to adjust the water outlet angle. Because overhead showerheads are relatively heavy, if the ball joint is made of plastic, the material strength is insufficient, resulting in a short lifespan; if it is made of copper alloy, the cost is high due to the material and wall thickness, making it uneconomical. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an economical ball joint and its processing method, which uses stainless steel and has a thinner wall thickness, resulting in better cost-effectiveness.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An economical ball joint includes a joint section, a connecting section, and a ball head section; the joint section, connecting section, and ball head section are integrally formed from stainless steel; an outlet is formed on the ball head section; a joint cavity is formed in the joint section, a connecting cavity is formed in the connecting section, and a spherical cavity is formed in the ball head section; the joint cavity, connecting cavity, spherical cavity, and outlet are sequentially connected; the diameter of the spherical cavity is larger than the diameter of the connecting cavity.

[0006] Furthermore, the inner wall of the connector cavity is formed with a threaded section, and the connector section and the shower pipe are threadedly connected through the threaded section.

[0007] Furthermore, the diameter of the joint cavity is larger than the diameter of the connecting cavity, and a step is formed between the joint cavity and the connecting cavity.

[0008] Furthermore, the outer diameter of the ball head segment is larger than the outer diameter of the connecting segment.

[0009] Furthermore, a rotating platform is formed on the outer wall of the joint section.

[0010] A method for processing a ball joint, which utilizes the economical ball joint described above, includes the following steps:

[0011] S01, stainless steel bars are extruded into joint sections, joint cavities, connecting cavities, and the upper half of the inner wall of the spherical cavity on a cold heading die using a cold heading process (as shown in the figure).

[0012] S02, the cold-forged part is clamped on a lathe, and the lower part of the part is rotated and extruded through a spinning process to form the lower half of the spherical surface of the outer wall of the ball head section and the lower half of the inner wall of the spherical cavity, while retaining the outlet.

[0013] S03, the upper half of the spherical surface of the outer wall of the ball joint section, the outer wall of the connecting section, and the threaded section are machined on a lathe; the machining is completed.

[0014] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0015] 1. In use, the connector section is connected to the water outlet of the shower pipe, and the ball head section is connected to the water inlet of the overhead shower head. Water flows from the shower pipe through the inside of the ball head connector to the overhead shower head. Since the diameter of the ball cavity is larger than the diameter of the connecting cavity, the wall thickness of the ball head section is thinner, thus saving more materials and reducing the cost. In addition, stainless steel is more economical than copper alloy.

[0016] 2. The end of the shower pipe abuts against the abutting step, and a sealing gasket can be installed between the abutting step and the end of the shower pipe.

[0017] Third, the outer diameter of the ball head section is larger than the outer diameter of the connecting section, and the diameter of the spherical cavity is larger than the diameter of the connecting cavity. The overall wall thickness of the ball head joint is thinner and more uniform, thus saving more materials and having better economic efficiency.

[0018] Compared with the prior art, the present invention provides an economical ball joint and processing method, using stainless steel material, with thinner and more uniform wall thickness, and thus better economic efficiency. Attached Figure Description

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see the appendix Figures 1 to 3 As shown, this invention provides an economical ball joint, comprising a joint section 1, a connecting section 2, and a ball joint section 3; the joint section 1, connecting section 2, and ball joint section 3 are integrally formed of stainless steel; a water outlet 32 ​​is formed on the ball joint section 3; a joint cavity 11 is formed inside the joint section 1, a connecting cavity 21 is formed inside the connecting section 2, and a spherical cavity 31 is formed inside the ball joint section 3; the joint cavity 11, connecting cavity 21, spherical cavity 31, and water outlet 32 ​​are sequentially connected; the diameter of the spherical cavity 31 is larger than the diameter of the connecting cavity 21. In use, the joint section 1 is connected to the water outlet of the shower pipe, and the ball joint section 3 is connected to the water inlet of the overhead shower head. Water flows from the shower pipe through the inside of the ball joint to the overhead shower head. Because the diameter of the spherical cavity 31 is larger than the diameter of the connecting cavity 21, the wall thickness of the ball joint section 3 is thinner, thus saving more material and reducing the cost. In addition, stainless steel is more economical than copper alloy.

[0028] Preferably, the inner wall of the connector cavity 11 is formed with a threaded section, and the connector section 1 and the shower pipe are threadedly connected through the threaded section 12.

[0029] Preferably, the diameter of the connector cavity 11 is larger than the diameter of the connecting cavity 21, and abutting step 13 is formed between the connector cavity 11 and the connecting cavity 21. The end of the shower pipe abuts against the abutting step 13, and a sealing gasket can be installed between the abutting step 13 and the end of the shower pipe.

[0030] Preferably, the outer diameter of the ball joint 3 is larger than the outer diameter of the connecting section 2. This allows the water outlet panel to have a certain degree of movement after the ball joint 3 is installed, preventing interference from the connecting section 2. The diameter of the spherical cavity 31 is larger than the diameter of the connecting cavity 21, resulting in a thinner and more uniform wall thickness for the ball joint, thus saving material and improving economic efficiency.

[0031] Preferably, such as Figure 1 As shown, a rotating platform 14 is formed on the outer wall of the joint section 1. There are two rotating platforms 14, which facilitates clamping and fixing with a wrench when installing the ball joint.

[0032] A method for processing a ball joint, which utilizes the economical ball joint described above, includes the following steps:

[0033] S01, stainless steel bars are cold-forged into joint section 1, joint cavity 11, connecting cavity 21, and the upper half of the inner wall of spherical cavity 31 by cold forging on a cold forging die (e.g., Figure 3 (as shown)

[0034] S02, the cold-forged part is clamped on the lathe and the lower part of the part is rotated and extruded by spinning process to form the lower half of the spherical surface of the outer wall of the ball head section 3 and the lower half of the inner wall of the spherical cavity 31, while retaining the water outlet 32.

[0035] S03, the upper half of the spherical surface of the outer wall of the ball head section 3, the outer wall of the connecting section 2, and the threaded section 12 are machined on a lathe; the machining is completed.

[0036] Compared with the prior art, the present invention provides an economical ball joint and processing method, using stainless steel material, with thinner and more uniform wall thickness, and thus better economic efficiency.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
