[0001] The utility model relates to the technical field of neck and shoulder massage devices, in particular to a kneading massage movement. Background Art

[0002] With the development of society, people's work and life pace is getting faster and faster, work pressure is getting greater and greater, and the time for relaxation is getting less and less. Over time, they will feel physically and mentally exhausted. Especially for people who work at a desk for a long time, the cervical spine is in a specific state for a long time, and the neck muscles are also in a non-coordinated stress state for a long time. The muscles and ligaments at the back of the neck are easily stretched and strained. Coupled with excessive torsion and lateral flexion, it is very easy to cause cervical spondylosis.

[0003] Therefore, various massagers for neck and shoulder massage have appeared on the market. However, these massagers, such as the Chinese patent No. 201510924022.1, disclose a kneading massager, in which the kneading movement structure includes a connecting rod structure. Due to the double-headed movable scheme of the connecting rod structure, the product assembly is difficult and the production efficiency is low, resulting in a high factory cost and low cost performance of the shoulder massager. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a connecting rod kneading massage movement which can realize the kneading massage function without a connecting rod structure, thereby effectively reducing the difficulty of assembling the massage product and improving the production efficiency and cost performance.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a kneading massage movement, comprising a shell, two groups of swing arms, two groups of torsion swing arms, a main shaft installed on the shell and a driving mechanism for driving the main shaft to rotate, the main shaft is fixedly equipped with two groups of eccentric cams and two groups of offset groove wheels, the two groups of torsion swing arms are movably connected to the two groups of eccentric cams respectively, and the two groups of torsion swing arms are movably connected to the two groups of offset groove wheels respectively, the inner end of the swing arm is provided with a linkage ring movably mounted on the eccentric cam, the linkage ring protrudes outward and is provided with an L-shaped anti-rotation portion, the shell is provided with a vertical slide groove, and the end of the L-shaped anti-rotation portion is laterally movably embedded in the vertical slide groove.

[0006] Preferably, the two groups of offset groove wheels are respectively arranged at two ends of the main shaft, the two groups of eccentric cams are respectively located on the inner sides of the two groups of offset groove wheels, and the eccentric cams and adjacent offset groove wheels are integrally injection molded.

[0007] Preferably, the L-shaped anti-rotation portion includes a protruding seat fixed to the outer wall of the linkage ring and a sliding column extending laterally from the protruding seat, and the sliding column is movably embedded in the vertical sliding groove.

[0008] Preferably, the upper end of the vertical slide groove extends upward to the opening.

[0009] Preferably, the driving mechanism comprises a driving inner shell, a brushless motor and a reduction wheel set installed in the driving inner shell, and the vertical slide groove is opened on the outer wall of the driving inner shell.

[0010] In another preferred embodiment, a vertical plate standing upright upward is provided at the bottom of the shell, and the vertical sliding groove is opened on the side wall of the vertical plate.

[0011] The beneficial effect of the utility model is that the utility model provides a kneading massage movement. The main shaft, eccentric cam and offset groove wheel in this scheme rotate under the action of the driving mechanism, and the swing arm performs a swinging motion under the driving action of the eccentric cam, so that the massage head at the outer end of the swing arm repeatedly presses the shoulder to achieve the massage effect of pressing and kneading. The torsion swing arm performs a torsion swing motion under the driving action of the offset groove wheel, so that the double massage balls at the outer end of the torsion swing arm twist. When the two groups of symmetrically arranged double massage balls twist, the distance between them constantly approaches and moves away, and when acting on the neck and shoulder area, a repeated grasping and pinching massage effect is produced. The design of the L-shaped anti-rotation part and the vertical slide groove is adopted to replace the design of the connecting rod structure on the market, which greatly simplifies the internal structure and assembly process of the kneading massage movement, significantly improves the assembly efficiency, reduces the production cost, and has high cost performance.
