Description

Technical Field

[0001] The utility model relates to a massage chair with a light shield. Background Art

[0002] At present, some massage chairs on the market are equipped with shading hoods, which can shield the user's head and isolate the glaring light, thereby improving the user experience of the massage chair. At present, the existing massage chairs with shading hoods are usually rotatably arranged on the massage chairs, and the shading hoods can be rotated according to the needs of the user, and the angle of the shading hood can be adjusted, and the shading hood can also be folded by rotating when not in use.

[0003] The hood needs to be positioned after rotation. Currently, the rotation positioning of the hood on the market usually relies on the damping mechanism at the shaft connection. The damping mechanism mainly relies on the friction between the components to achieve the positioning of the hood after rotation. The damping effect will weaken after long-term use. As the massage chair vibrates during operation, it is easy to cause the hood to rotate by itself, and the reliability is poor. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a massage chair with a light shield, which has a simple structure and better rotation and positioning effect.

[0005] To achieve the above-mentioned purpose, the utility model provides a massage chair with a light shield, comprising a massage chair body and a light shield. The inner sides of the two ends of the light shield and the two sides of the upper end of the massage chair body form a rotational connection, so that the light shield can rotate relative to the massage chair body. The light shield can adjust its shielding angle by rotating. When not in use, the light shield can also be rotated to the rear of the massage chair body for folding. The inner sides of the two ends of the light shield are provided with a first connection seat, and the two sides of the upper end of the massage chair body are provided with a second connection seat. A shaft is passed through the first connection seat and the second connection seat. The first connection seat and the second connection seat form a rotational connection through the shaft. The first connection seat and the second connection seat can move relative to each other along the axial direction of the shaft. The corresponding axial ends of the first connection seat and the second connection seat are both provided with annularly distributed teeth. A spring is provided between the first connection seat and the second connection seat to drive the teeth of the first connection seat and the second connection seat to axially press and bite together, or the light shield includes an elastic component for driving the first connection seat to move toward the second connection seat so that the teeth at one end thereof are axially bitten together.

[0006] In the above structure, the first connection seat and the second connection seat can move relative to each other in the axial direction of the shaft, and the teeth at one end thereof are driven to bite together by a spring or elastic component. When a large driving force is applied to the light shield, the component force generated at the tooth matching position is used to drive the first connection seat and the second connection seat to move in directions away from each other, so that the teeth are disengaged, so that the light shield can be driven to rotate. When the driving force disappears, under the action of the elastic force, the teeth of the first connection seat and the second connection seat bite again, and the light shield can be positioned so that the light shield will not rotate by itself, thus realizing the function of rotation positioning. Compared with the method of relying on friction to achieve positioning in the prior art, this method of using teeth to achieve positioning is more reliable and has a longer service life. In particular, the massage chair is not easy to rotate by itself when it is working and shaking.

[0007] Furthermore, a limiting portion is provided at one end of the shaft corresponding to the second connecting seat, and the limiting portion and the second connecting seat constitute an axial and circumferential limiting fit to prevent the shaft from escaping from the second connecting seat. One end of the shaft corresponding to the first connecting seat is connected to a limiting block by a screw, and the limiting block and the first connecting seat constitute an axial limiting fit to prevent the shaft from escaping from the first connecting seat. The spring sleeve is arranged on the shaft, and both ends of the spring respectively form abutment fit with the second connecting seat and the limiting block, and the spring can drive the first connecting seat to move toward the second connecting seat.

[0008] Furthermore, both ends of the light shield have bosses formed on the inner side, and recesses formed on the corresponding positions of the outer side. The first connecting seat and the bosses are fixed by screws. The outer sides of both ends of the light shield include cover plates that cooperate with the recess to seal. The spring and the limit block are accommodated in the first chamber formed between the recess and the cover plate. The structure is compact and beautiful.

[0009] Furthermore, the second connecting seat and the massage chair body are fixed by screws, and a second chamber is formed at the connection, the limiting portion at one end of the shaft is accommodated in the second chamber, one side of the limiting portion includes a notch, and the second connecting seat includes a stopper that fits in the notch and cooperates with the limiting portion to limit the rotation of the shaft relative to the second connecting seat, and the structure is compact and beautiful.

[0010] In another optional scheme, the elastic component is connected between the first connecting seats on the inner sides of the two ends of the light shield, the end of the shaft corresponding to the first connecting seat is fixed to the first connecting seat, and the end of the shaft corresponding to the second connecting seat forms a detachable plug-in fit with the second connecting seat, and the elastic component keeps the tooth portion at one end of the first connecting seat and the tooth portion at one end of the second connecting seat in a bite state. Specifically, when the light shield is not installed on the massage chair body, the distance between the two first connecting seats on the inner sides of the two ends of the light shield is smaller than when it is installed on the massage chair body, and the elastic component can always press the two first connecting seats tightly in contact with the two second connecting seats.

[0011] In a further refinement, the light shield is made of an elastic material such as metal, nylon, etc., and the elastic component is formed by the light shield. The elasticity of the light shield itself drives the first connection seat to press and contact the second connection seat.

[0012] In another further refined scheme, a U-shaped elastic metal plate is tightly fixed to the inner side of the light shield, the elastic component is composed of the elastic metal plate, and the first connecting seats on the inner sides of the two ends of the light shield are respectively fixed at the two ends of the elastic metal plate. The elastic metal plate can reduce the requirements for the material of the light shield, and can play a role in maintaining the stability of the overall structural shape of the light shield, and improve the effect of the elastic force applied to the two first connecting seats.

[0013] The beneficial effects of the present invention are as follows: compared with the prior art, the rotation positioning structure between the light shielding cover and the massage chair body of the massage chair of the present invention is simple in structure and more reliable to use; the light shielding cover is not easy to loosen or rotate by itself after being positioned, and the effect is more obvious especially when the massage chair is working and shaking.

[0019] The massage chair with a light shield of the utility model is implemented as follows Figure 1-4As shown: it includes a massage chair body 1 and a light shield 2. The inner sides of the two ends of the light shield 2 and the two sides of the upper end of the massage chair body 1 form a rotational connection, so that the light shield 2 can rotate relative to the massage chair body 1. The light shield 2 can adjust its shielding angle by rotating. When not in use, the light shield 2 can also be rotated to the rear of the massage chair body 1 for folding. The inner sides of the two ends of the light shield 2 are provided with a first connecting seat 3, and the two sides of the upper end of the massage chair body 1 are provided with a second connecting seat 4. A shaft 5 is passed through the first connecting seat 3 and the second connecting seat 4. The first connecting seat 3 and the second connecting seat 4 form a rotational connection through the shaft 5. The first connecting seat 3 and the second connecting seat 4 can move relative to each other along the axial direction of the shaft 5. The corresponding axial ends of the first connecting seat 3 and the second connecting seat 4 are both provided with annularly distributed teeth (31, 41). The shaft 5 is passed through the center position of the first connecting seat 3 and the second connecting seat 4, and the annularly distributed teeth (31, 41) are arranged along the center circumference of the first connecting seat 3 and the second connecting seat 4.

[0020] In this embodiment, a spring 6 is provided between the first connection seat and the second connection seat 4 to drive the teeth (31, 41) of the first connection seat 3 and the second connection seat 4 to axially press and bite together. When the two are bitten, the convex / concave part of the teeth of the first connection seat 3 and the concave / convex part of the teeth of the second connection seat 4 fit together, which can prevent the first connection seat 3 from rotating relative to the second connection seat 4, thereby preventing the light shield 2 from rotating. However, when a large driving force is applied to the light shield 2, the component force generated at the tooth matching position drives the first connection seat 3 and the second connection seat 4 to move in a direction away from each other, so that the teeth are disengaged, so that the light shield 2 can be driven to rotate. When the driving force disappears, under the action of the elastic force, the teeth of the first connection seat 3 and the second connection seat 4 are re-engaged, and the rotation of the light shield 2 is re-positioned, so that the light shield 2 will not rotate by itself. Compared with the method of relying on friction to achieve positioning in the prior art, this method of using teeth to achieve positioning is more reliable and has a longer service life. In particular, it is not easy for the massage chair to rotate by itself when it is shaking during operation.

[0021] like Figure 3 , 4 As shown, one end of the shaft 5 corresponding to the second connecting seat 4 is provided with a limiting portion 51, and the limiting portion 51 and the second connecting seat 4 constitute an axial and circumferential limiting fit to prevent the shaft 5 from escaping from the second connecting seat 4. One end of the shaft 5 corresponding to the first connecting seat 3 is connected to a limiting block 52 by a screw, and the limiting block 52 and the first connecting seat 3 constitute an axial limiting fit to prevent the shaft 5 from escaping from the first connecting seat 3. The spring 6 is sleeved on the shaft 5, and the two ends of the spring 6 respectively form abutment fit with the second connecting seat 4 and the limiting block 52, and the spring 6 can drive the first connecting seat 3 to move toward the second connecting seat 4.

[0022] The two ends of the light shield 2 are formed with a boss 21 on the inner side, and a recess 22 is formed at a corresponding position on the outer side. The first connecting seat 3 and the boss 21 are fixed by screws. The outer sides of the two ends of the light shield 2 include a cover plate 23 that cooperates with the recess 22 to close. The cover plate 23 is fixed to the light shield 2 by buckles or screws. The spring 6 and the limit block 52 are accommodated in the first chamber a formed between the recess 22 and the cover plate 23. The structure is compact and beautiful.

[0023] The second connecting seat 4 and the massage chair body 1 are fixed by screws, and a second chamber b is formed at the connection. The limiting portion 51 at one end of the shaft 5 is accommodated in the second chamber b, and one side of the limiting portion 51 includes a notch 511. The second connecting seat 4 includes a stopper 42 that fits in the notch 511 and cooperates with the limiting portion 51 to limit the rotation of the shaft 5 relative to the second connecting seat 4. The structure is compact and beautiful.

[0024] Another embodiment of the present invention is Figure 5 As shown, the difference from the above embodiment is that in another embodiment, there is no limiting structure between the second connecting seat 4 and the shaft 5, and there is no spring 6 between the first connecting seat 3 and the second connecting seat 4. Specifically: the light shield 2 includes an elastic component for driving the first connecting seat 3 to move toward the second connecting seat 4 so that the teeth (31, 41) at one end thereof are axially engaged together.

[0025] The elastic component is connected between the first connecting seats 3 on the inner sides of both ends of the light shading hood 2, the end of the shaft 5 corresponding to the first connecting seat 3 is fixed to the first connecting seat 3, and the end of the shaft 5 corresponding to the second connecting seat 4 forms a detachable plug-in fit with the second connecting seat 4, which is convenient for disassembly and assembly. The shaft 5 supports the weight of the light shading 2, and the shaft 5 can also be used to realize the relative rotation of the first connecting seat 3 and the second connecting seat 4. The elastic component keeps the tooth portion 31 at one end of the first connecting seat 3 and the tooth portion 41 at one end of the second connecting seat 4 in a bite state. Specifically, when the light shading hood 2 is not installed on the massage chair body 1, the distance between the two first connecting seats 3 on the inner sides of both ends of the light shading hood 2 is smaller than when it is installed on the massage chair body 1, and the elastic component can always press the two first connecting seats 3 tightly in contact with the two second connecting seats 4 respectively.

[0026] A U-shaped elastic metal plate 7 is tightly fixed to the inner side of the light shield 2, and the elastic component is composed of the elastic metal plate 7. The first connecting seats 3 on the inner sides of the two ends of the light shield 2 are respectively fixed on the two ends of the elastic metal plate 7. The elastic metal plate 7 can reduce the requirements on the material of the light shield 2, and can play a role in maintaining the stability of the overall structural shape of the light shield 2, and improve the effect of the elastic force applied to the two first connecting seats 3.

[0027] In other similar embodiments, the light shield 2 is made of an elastic material such as metal, nylon, etc., the elastic component is composed of the light shield 2, and the elasticity of the light shield 2 itself drives the first connecting seat 3 to be pressed and contacted on the second connecting seat 4.

[0028] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the technical solution of the present invention are all included in the protection scope of the present invention.
