Description

Technical Field

[0001] The utility model relates to the technical field of health care equipment, in particular to a massage head structure with a clip spring limiting function. Background Art

[0002] Currently commonly used massage sticks generally include telescopic function, bead function and vibration function. The telescopic mechanism that realizes the telescopic function and the vibrator installed inside the massage head are generally driven by a hollow tube through the wire to drive the motor. The telescopic mechanism can move up and down and rotate, thereby driving the massage head to move up and down and rotate, and at the same time, the massage head can also realize the vibration function.

[0003] Existing massage heads are usually connected to the telescopic mechanism through a hollow tube, and the other end of the hollow tube is directly connected to the massage head through upper and lower gaskets. During use, the stamping pressure will cause the hollow tube to deform, causing the outer diameter of the hollow tube to increase and thus jam the massage head. The inner hole size of the hollow tube will also be deformed. Therefore, this process technology has poor structural stability, affecting the life of the vibration function and thus affecting the normal operation of the massage head. Utility Model Content

[0004] The purpose of the present invention is to provide a massage head structure with a retaining spring, aiming to solve the above-mentioned technical problems. The present invention ensures the firmness and stability of the connection between the hollow tube and the mounting shell, fills and adjusts the gaps in different parts, and thus ensures that the inner hole of the hollow tube does not deform, thereby ensuring the normal operation and safety of the massage head, reducing the probability of malfunction and extending the service life of the massage head.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions:

[0006] A massage head structure with a retaining spring limiter includes a vibrating outer cylinder, a retaining spring limiter assembly, a mounting shell and a hollow tube. The lower end of the vibrating outer cylinder is connected to the mounting shell, and the upper end of the hollow tube is connected to the retaining spring limiter assembly. The retaining spring limiter assembly includes an upper retaining spring limiter group, a movable rotor and a lower retaining spring limiter group, which are arranged in sequence from top to bottom. The upper retaining spring limiter group and the movable rotor are both installed in the mounting shell. The lower retaining spring limiter group is located below the mounting shell. The upper end of the hollow tube extends upward through the lower retaining spring limiter group, the movable rotor and the upper retaining spring limiter group in sequence.

[0007] Furthermore, the hollow tube is provided with an upper clamping groove, an upper limit portion, a rotor mounting portion, a lower limit portion, and a lower clamping groove in order from top to bottom, and the movable rotor is sleeved on the rotor mounting portion.

The upper retaining spring is engaged with the upper retaining groove, and the upper gasket is sleeved onto the upper limit portion. The lower end surface of the upper gasket abuts the upper end surface of the movable rotor. The upper retaining spring secures and maintains the position of the components. The upper gasket prevents the upper retaining spring from loosening, adjusts the pressure of the upper retaining spring, improves reliability, fills and adjusts gaps in different locations, ensures the secureness and stability of the connection, and also provides a certain sealing effect.

[0009] Furthermore, the lower retaining spring assembly includes a lower retaining spring and a lower gasket. The lower retaining spring is engaged with the lower retaining groove, and the lower gasket is sleeved onto the lower retaining portion. The upper end surface of the lower gasket abuts the lower end surface of the movable rotor. The lower retaining spring secures and maintains the position of the components. The lower gasket prevents the lower retaining spring from loosening, adjusts its pressure, improves reliability, fills and adjusts gaps in different locations, ensures a secure and stable connection, and also provides a certain sealing effect.

When the massage head is in use, the stamping pressure can be effectively avoided to cause deformation of the hollow tube, thereby preventing the outer diameter of the hollow tube from becoming larger and thus jamming the massage head, and avoiding deformation of the inner hole size of the hollow tube, and other problems, and has good stability.

[0016] 2. The massage head structure with a retaining spring limiter in this utility model ensures the firmness and stability of the connection between the hollow tube and the mounting shell, fills and adjusts the gaps in different parts, and thus ensures that the inner hole of the hollow tube does not deform, thereby ensuring the normal operation and safety of the massage head, reducing the probability of malfunction and extending the service life of the massage head.
