Description

Technical Field

[0001] This utility model relates to the technical field of one-way valve cores for car massage chairs, specifically a valve core for car massage chairs with a protective structure. Background Technology

[0002] A car massage chair is a massage system designed for vehicle seats, typically integrated into the seat back and cushion. It provides massage functions through pneumatic, mechanical, or hybrid methods to enhance driving and riding comfort. Its core structure includes a control system, power unit, actuators (airbags / mechanical components), and various valves.

[0003] One-way valves are used in car massage chairs to ensure stable airbag pressure, prevent air leakage, and protect the air pump from backflow. However, the one-way valve cores currently used in car massage chairs require a sealing ring to be installed on the valve core before assembly. Currently, the sealing ring needs to be opened first before it is fitted onto the valve core, which is quite troublesome during installation and when the sealing ring needs to be replaced later. Therefore, we propose a valve core for car massage chairs with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a valve core for a car massage chair with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve core for a car massage chair with a protective structure, comprising a valve core body, a mounting base and a support spring, wherein a sealing ring is provided on the left side of the valve core body, and a fastening device for installing the sealing ring is provided on the left side of the valve core body;

[0006] The fastening device includes:

[0007] Embedded groove, used for installing sealing rings;

[0008] The contact plate is used to fix the sealing ring in conjunction with the valve core body;

[0009] Bolts are used to secure the contact plate.

[0010] Preferably, the left side of the mounting base is fixed to one end of the support spring, and the other end of the support spring is fixed to the inside of the valve core body. The valve core body has through holes at the top and bottom. The valve core body can be installed by threading the mounting base to the valve body, and the valve core body is supported by the support spring.

[0011] Preferably, the embedding groove is located on the left side of the valve core body, and the abutment plate has an installation groove. The bolt passes through the installation groove and is threaded to the left side of the valve core body. By fitting the sealing ring into the embedding groove, passing the bolt through the installation groove, and making the abutment plate abut against the sealing ring, the bolt is threaded to the valve core body and tightened, thus completing the installation of the sealing ring. When it is necessary to disassemble the sealing ring, simply unscrew the bolt to remove the abutment plate, and then the sealing ring can be replaced, making replacement convenient.

[0012] Preferably, a threaded hole is provided on the left side of the valve core body, and a bolt can be threaded into the threaded hole on the left side of the valve core body to facilitate the disassembly and assembly of the contact plate.

[0013] Compared with the prior art, this utility model provides a valve core for a car massage chair with a protective structure, which has the following beneficial effects:

[0014] This car massage chair valve core with a protective structure uses a fastening device to install the sealing ring. By fitting the sealing ring into the embedded groove, passing the bolt through the mounting groove, and making the contact plate abut against the sealing ring, the bolt is threadedly connected to the valve core body and tightened. When the sealing ring needs to be removed, simply unscrew the bolt to remove the contact plate, and then the sealing ring can be replaced, making replacement convenient. Attached Figure Description

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a valve core for a car massage chair with a protective structure, including a valve core body 1, a mounting base 2 and a support spring 5. A sealing ring 4 is provided on the left side of the valve core body 1, and a fastening device 3 for installing the sealing ring 4 is provided on the left side of the valve core body 1. The fastening device 3 includes: an embedding groove 31, a contact plate 32, a bolt 33, and a mounting groove 34.

[0020] The left side of the mounting base 2 is fixed to one end of the support spring 5, and the other end of the support spring 5 is fixed to the inside of the valve core body 1. The top and bottom of the valve core body 1 are provided with through holes 6. By threading the mounting base 2 to the valve body, the installation of the valve core body 1 and the valve body can be completed. The support spring 5 supports the valve core body 1.

[0021] An embedded groove 31 is located on the left side of the valve core body 1. An installation groove 34 is provided on the abutment plate 32. A bolt 33 passes through the installation groove 34 and is threadedly connected to the left side of the valve core body 1. By fitting the sealing ring 4 into the embedded groove 31 and passing the bolt 33 through the installation groove 34, the abutment plate 32 abuts against the sealing ring 4. The bolt 33 is then threadedly connected to the valve core body 1 and tightened, thus completing the installation of the sealing ring 4. When it is necessary to disassemble the sealing ring 4, simply unscrew the bolt 33 to remove the abutment plate 32, and the sealing ring 4 can be replaced. This facilitates replacement. Furthermore, the contact between the abutment plate 32 and the valve body protects the valve core body 1, preventing direct contact between the valve core body 1 and the valve body. This prevents wear of the valve core body 1 from prolonged use and affects normal operation.

[0022] A threaded hole 7 is provided on the left side of the valve core body 1. The bolt 33 can be threaded into the threaded hole 7 on the left side of the valve core body 1 to facilitate the disassembly and assembly of the contact plate 32.

[0023] In this utility model, during use, the sealing ring 4 is first fitted into the embedding groove 31, the bolt 33 is passed through the mounting groove 34, so that the contact plate 32 abuts against the sealing ring 4, the bolt 33 is threadedly connected to the valve core body 1 and tightened, thus completing the installation of the sealing ring 4. When it is necessary to disassemble the sealing ring 4, simply unscrew the bolt 33 to remove the contact plate 32, and then the sealing ring 4 can be replaced, which is convenient for replacement.

[0024] After the sealing ring 4 is installed, the valve core body 1 and the valve body can be installed by threading the mounting base 2 to the valve body.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
