Description

Technical Field

[0001] The utility model relates to the technical field of massage equipment, in particular to a cervical massager. Background Art

[0002] A cervical massage seat is a health care device that combines physical support with massage functions. It usually has a built-in motor-driven massage head that applies pressure to the back of the user's neck, aiming to relax muscles, relieve soreness and promote local blood circulation.

[0003] However, the width of the pillows of existing cervical massage seats is generally fixed, which leads to significant limitations: on the one hand, it cannot adapt to the differences in neck width among different users. A pillow that is too wide will cause the sides of the neck to be suspended in the air and lose support, while a pillow that is too narrow will compress the shoulders and neck and cause discomfort; on the other hand, the fixed width makes it difficult to ensure that the massage head acts accurately on the key muscle groups and acupoints behind the user's neck, affecting the massage effect. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the constant width of the pillow body of the cervical massage seat in the prior art, thereby providing a cervical massager suitable for different groups of people.

[0005] To this end, the present invention provides a cervical massager, comprising: two massage seats, which are arranged opposite to each other; at least one set of adjustment components, including a knob, and a screw driven by the knob and rotating around its own axis, the screw having a first screw portion and a second screw portion with opposite thread screwing directions, and the two massage seats are respectively provided with a first threaded hole and a second threaded hole that are threadedly connected to the first screw portion and the second screw portion.

[0006] The knob is fixedly arranged between the first screw portion and the second screw portion.

[0007] There are two groups of adjustment components, which are respectively installed at two ends of the massage seat in the length direction.

[0008] The massage seat is formed with a mounting groove for accommodating the knob body, and a notch for allowing a portion of the knob to extend out of the notch.

[0009] The ends of the first screw portion and the second screw portion are both provided with a clamping groove for installing a clamping ring, and the clamping ring is used to abut against the side walls of the first threaded hole and the second threaded hole.

[0010] There are two groups of adjustment components, which are respectively installed at two ends of the massage seat in the length direction.

[0011] The technical solution of this utility model has the following advantages:

[0012] 1. The cervical massager provided by the utility model drives the screw to rotate by turning the knob. Since the thread directions of the first screw portion and the second screw portion are opposite, the two massage seats can be moved synchronously toward or in opposite directions to adjust the width between the two massage seats, which is suitable for different groups of people. In addition, a single operation of the knob can synchronously control the massage seats on both sides, avoiding the tedious step-by-step adjustment and making it more convenient for users to use.

[0013] 2. The cervical massager provided by the present invention has two sets of adjustment components respectively arranged at both ends of the massage seat in the length direction, eliminating the risk of tilting caused by single-point adjustment and ensuring that the two massage seats always move in parallel.

[0023] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Example

[0025] This embodiment provides a cervical massager, such as Figure 1 and Figure 2 As shown, it includes two massage seats 1 and an adjustment component.

[0026] The two massage seats 1 are arranged relative to each other. Figure 2 As shown, the two massage seats 1 have two sets of first threaded holes 6 and second threaded holes 7 arranged opposite to each other. Figure 3 and Figure 4 As shown, the massage seat 1 is formed with a mounting groove 8 for accommodating the main body of the knob 2, and a notch 9 for allowing a portion of the knob 2 to extend out.

[0027] Two sets of adjustment components are respectively installed at the two ends of the length direction of the massage seat 1. Figure 2 and Figure 3As shown, the adjustment assembly includes a knob 2 and a screw 3 driven by the knob 2 to rotate about its own axis. The screw 3 has a first screw portion 4 and a second screw portion 5 with opposite threading directions (for example, the first screw portion 4 is left-handed and the second screw portion 5 is right-handed). The two massage seats 1 are respectively provided with a first threaded hole 6 and a second threaded hole 7 that are threadedly connected to the first and second screw portions 4 and 5. In this embodiment, the knob 2 is fixedly disposed between the first and second screw portions 4 and 5. The ends of the first and second screw portions 4 and 5 are each provided with a retaining groove 10 for mounting a retaining ring (not shown). The retaining ring is designed to abut against the side walls of the first and second threaded holes 6 and 7, thereby preventing the screw 3 from being dislodged from the massage seat 1. In this embodiment, the knob 2 and screw 3 are integrally formed by injection molding.

[0028] The cervical massager provided by the utility model drives the screw 3 to rotate by rotating the knob 2. Since the thread directions of the first screw part 4 and the second screw part 5 are opposite, the two massage seats 1 can be moved synchronously towards or in opposite directions to adjust the width between the two massage seats 1. It is suitable for different people. In addition, a single operation of the knob can synchronously control the massage seats on both sides, avoiding the tedious step-by-step adjustment and making it more convenient for users to use.

[0029] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
