Description

Technical Field

[0001] The utility model belongs to the field of health care equipment and relates to an eccentric rotating chair with adjustable rotation radius. Background Art

[0002] Application document CN201120263603.2 discloses an eccentric rotating chair that utilizes the principles of revolution and rotation to fully mobilize the user's cervical and lumbar vertebrae. The technical solution also includes a horizontal telescopic rod secured by a fixing bolt. Adjusting the length of the rod adjusts the radius of the chair's revolution. The greater the extension of the telescopic rod, the greater the torque. However, the telescopic rod is typically hollow, so a horizontally arranged telescopic rod poses a risk of bending. Adjusting the length of the telescopic rod also requires tightening the bolt, which is cumbersome. Utility Model Content

[0003] In order to solve the above-mentioned problems of instability and inconvenient adjustment, the utility model provides an eccentric rotating chair with a stable structure and convenient adjustment.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an eccentric rotating chair with an adjustable rotation radius, comprising a base, an eccentric rotating arm being inserted above the center of the base, the two ends of the eccentric rotating arm having different distances from the center of the base, and sockets being respectively provided at both ends of the eccentric rotating arm, and a seat being inserted into any one of the sockets.

[0005] Preferably, the base includes a revolving bearing seat, a revolving shaft is rotatably connected above the revolving bearing seat, the revolving shaft is provided with an annular protrusion, and the rotating arm is provided with a socket corresponding to the revolving shaft.

[0006] Preferably, the socket is in the shape of a hollow cylinder.

[0007] Preferably, the seat includes a rotating bearing seat at the bottom, and a rotating shaft is rotatably connected to the top of the rotating bearing seat.

[0008] Preferably, the diameter of the rotating bearing seat gradually decreases from top to bottom, the diameter of the lower end of the rotating bearing seat is smaller than the inner diameter of the socket, and the diameter of the upper end of the rotating bearing seat is larger than the inner diameter of the socket.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] When the eccentric rotating arm of the present invention rotates, the rotation radius at both ends is different. Therefore, when the seat is inserted into different ends of the eccentric rotating arm, the revolution radius of the seat is different. Therefore, the user can insert the seat into any end of the eccentric rotating arm as needed. This adjustment process is simple and convenient, and the eccentric rotating arm has stronger bearing capacity, simple structure and stability.

[0011] The utility model can conveniently adjust the revolution radius of the chair and is suitable for users of different body shapes.

[0012] The utility model can help the user to move the body while sitting, so as to achieve the purpose of exercising the waist. Moreover, this activity is highly safe and can be performed indoors, so it is suitable for use by the elderly. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1 、 Figure 2 As shown, in order to provide a rotating chair with a stable structure and easy to adjust the rotation radius, the utility model provides an eccentric rotating chair with an adjustable rotation radius, including a base 1, an eccentric rotating arm 2 is inserted above the center of the base 1, and the eccentric rotating arm 2 can rotate. The distances between the two ends of the eccentric rotating arm 2 and the center of the base 1 are different, so the rotation radius of the two ends of the eccentric rotating arm 2 is different. Sockets 21 are respectively provided at both ends of the eccentric rotating arm 2, and a seat 3 is inserted into any socket 21, so the seat 3 can realize revolution and rotation.

[0020] Specifically, when the eccentric rotating arm 2 of the present invention rotates, the rotation radius at its two ends is different. Therefore, when the seat 3 is inserted into different ends of the eccentric rotating arm 2, the revolution radius of the seat 3 is different. Therefore, the user can insert the seat 3 into any end of the eccentric rotating arm 2 as needed. This adjustment process is simple and convenient, and the eccentric rotating arm 2 has stronger bearing capacity, simple structure and stability.

[0021] In order to reduce friction during revolution and rotation:

[0022] Furthermore, the base 1 includes a revolving bearing seat 11, to which a revolving shaft 12 is rotatably connected. The revolving shaft 12 is provided with an annular protrusion 13. The eccentric rotating arm 2 is provided with a socket corresponding to the revolving shaft 12, with the socket being located at different distances from the ends of the eccentric rotating arm 2. A bearing is provided within the revolving bearing seat 11 to reduce resistance to the revolving shaft 12 during rotation. The diameter of the annular protrusion 13 is larger than the diameter of the socket. When the revolving shaft 12 is inserted into the socket, the annular protrusion 13 supports the revolving shaft 12, preventing it from falling and contacting the revolving bearing seat 11.

[0023] Furthermore, the socket 21 is in the shape of a hollow cylinder.

[0024] Furthermore, the seat 3 includes a rotation bearing seat 31 at the bottom, and a rotation shaft 32 is rotatably connected to the top of the rotation bearing seat 31. The rotation bearing seat 31 reduces the resistance of the rotation shaft 32 when it rotates.

[0025] Furthermore, the diameter of the rotating bearing seat 31 gradually decreases from top to bottom. The diameter of the lower end of the rotating bearing seat 31 is smaller than the inner diameter of the socket 21, and the diameter of the upper end of the rotating bearing seat 31 is larger than the inner diameter of the socket 21. Therefore, when the rotating bearing seat 31 is inserted into the socket 21, the rotating bearing seat 31 will not pass through the socket 21. At the same time, friction is generated between the rotating bearing seat 31 and the socket 21, making it difficult for the rotating bearing seat 31 and the socket 21 to rotate relative to each other.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
