Description

Technical Field

[0001] This utility model belongs to the technical field of rheumatoid arthritis physiotherapy equipment, and in particular relates to a rheumatoid arthritis physiotherapy device. Background Technology

[0002] Traditional physiotherapy methods for rheumatoid arthritis mainly include hot compresses, massage, and acupuncture. These methods can promote local blood circulation and relieve pain to some extent, but their effects are often limited and require patients to adhere to them for a long time.

[0003] Because the surface of the knee joint is curved, existing massage devices on the market only use vibration motors to simulate the effect of massage. Although this method can provide a certain massage effect, it is inferior to the effect of massage components rolling on the skin surface. Furthermore, because the surface of the human knee is curved, the massage balls in the massage components cannot adjust their height according to the changes in the surface of the human knee during the rolling massage. As a result, the massage balls cannot provide targeted massage to the human knee area, and the massage ball massage method still cannot achieve a good massage effect. Utility Model Content

[0004] The purpose of this invention is to provide a rheumatic joint physiotherapy device in which the massage ball can adapt to changes in the surface of the human knee during the rolling massage process, thereby improving the massage effect to a certain extent.

[0005] The aforementioned rheumatoid arthritis physiotherapy device includes a housing with a knee brace that can be fixed to the knee of a human body. A motor is installed on the inner top of the housing, and the drive end of the motor is connected to a rotating shaft. Several pressing arms distributed around the circumference of the rotating shaft are hinged to the rotating shaft. All pressing arms swing up and down. Massage balls are provided at the pressing ends of the pressing arms. Adjustment components are provided between the pressing arms and the rotating shaft to allow the massage balls to closely adhere to the surface of the human skin for massage.

[0006] Furthermore, the adjustment assembly includes a sleeve, inside which a freely movable rod is inserted. One end of the sleeve is hinged to a pressing arm, and one end of the movable rod is hinged to a rotating shaft. A spring is provided between the movable rod and the sleeve to push both to extend.

[0007] Furthermore, a first limiting ring is fitted onto the sleeve, a second limiting ring is fitted onto the movable rod, and the two ends of the spring abut against the first limiting ring and the second limiting ring respectively and are independently fitted onto the movable rod and the sleeve.

[0008] Furthermore, each pressing end of the pressing arm is fixed with a ball seat, and the massage ball is installed in the ball seat and can roll freely.

[0009] Furthermore, the opening of the outer casing is provided with a protective cloth that encloses all the massage balls inside the casing.

[0010] Furthermore, there are 6 pressing arms, which are evenly distributed along the circumference of the rotating shaft.

[0011] Furthermore, the pressing arm has a "V" shaped structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention provides an adjustment component between the pressing arm and the rotating shaft to allow the pressing arm to swing, enabling the massage ball to adapt to changes in the surface of the human knee and maintain constant contact with the knee surface for massage, thereby improving the massage effect to a certain extent.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0020] The rheumatoid arthritis physiotherapy device described in this embodiment, such as Figures 1 to 3 As shown, it includes an outer shell 1, on which a knee brace 8 is provided to fix it to the knee of a human body. The knee brace 8 is made of elastic fabric, which fixes the outer shell 1 to the knee of a human body through its high resilience.

[0021] like Figure 2As shown, the knee pad 8 has a through hole that connects the inside and outside. The outer shell 1 has a structure that is wider at the bottom and narrower at the top. The diameter of the lower half is larger than the diameter of the through hole, and the diameter of the upper half is smaller than the diameter of the through hole. When in use, the upper half of the outer shell 1 passes through the through hole of the knee pad 8 from the inside to the outside. When the lower half of the outer shell 1 can no longer pass through the through hole, the knee pad 8 is worn on the knee of the human body, thereby fixing the outer shell 1 to the knee of the human body.

[0022] A motor 3 is installed on the inner top of the outer casing 1. The drive end of the motor 3 is connected to a rotating shaft 4. The center line of the rotating shaft 4 is on the same straight line as the center line of the drive end of the motor 3. The upper end of the rotating shaft 4 has a socket for inserting the drive end of the rotating shaft 4. During installation, the drive end of the motor 3 is inserted into the socket to connect with the rotating shaft 4.

[0023] A number of pressing arms 5 are hinged to the rotating shaft 4, distributed along the circumference of the rotating shaft 4. All pressing arms 5 swing up and down. There are 6 pressing arms 5, which are evenly distributed along the circumference of the rotating shaft 4. 6 hinge seats are fixed to the lower end of the rotating shaft 4, and the hinge ends of the pressing arms 5 are hinged to the lower end of the rotating shaft 4 through the hinge seats.

[0024] The pressing end of the pressing arm 5 is equipped with massage balls 7, and each pressing end of the pressing arm 5 is fixed with a ball seat 6. The massage balls 7 are installed in the ball seat 6 and can roll freely. When driven by the motor 3, all the massage balls 7 rotate in a circle around the rotating shaft 4. During the rotation, the massage balls 7 also have a massage effect. During the massage, they come into contact with the surface of the human skin, and friction is generated between the massage balls 7 and the surface of the human skin. The ball seat 6 between the massage balls 7 and the pressing arm 5 allows the massage balls 7 to roll freely in the ball seat 6, thereby reducing the friction generated between the massage balls 7 and the surface of the human skin. This also reduces the resistance of the rotating shaft 4 during the rotation process, making the rotation of the rotating shaft 4 smoother.

[0025] like Figure 1 and Figure 4 As shown, a sleeve 10 is hinged to the pressing arm 5, and a movable rod 12 is hinged to the rotating shaft 4. The movable end of the movable rod 12 is inserted into the sleeve 10 and can extend and retract freely. A spring 11 is provided between the movable rod 12 and the sleeve 10 to push both to extend. This section constitutes an adjustment component for allowing the massage balls 7 to adhere closely to the surface of the human skin for massage. In the natural state of the spring 11, all the massage balls 7 can adhere to the surface of the human knee skin. During use, the pressing arm 5 swings, and the length between the sleeve 10 and the movable rod 12 extends and retracts relative to each other. When shortened, the spring 11 is compressed, and the massage balls 7 adhere to the surface of the human skin under the push of the spring 11. The spring 11 needs to have a certain strength; otherwise, although the massage balls 7 can roll along the human knee, they will not have sufficient pressing strength, resulting in poor massage effect. Therefore, the spring 11 must have a certain strength.

[0026] A first limiting ring 14 is fitted onto the sleeve 10, and a second limiting ring 15 is fitted onto the movable rod 12. The two ends of the spring 11 abut against the first limiting ring 14 and the second limiting ring 15, respectively, and are independently fitted onto the movable rod 12 and the sleeve 10. Under the push of the spring 11, the sleeve 10 and the movable rod 12 are in an extended state. When the pressing arm 5 swings upward, the movable rod 12 retracts into the sleeve 10, and the spring 11 is compressed.

[0027] A first hinge support is fixed on the pressing arm 5, a second hinge support is fixed on the rotating shaft 4, a first connecting ring 17 is fixed on the hinge end of the sleeve 10, and a second connecting ring 16 is fixed on the hinge end of the movable rod 12. The first connecting ring 17 and the second connecting ring 16 are respectively hinged to the first hinge support and the second hinge support through the hinge post 18.

[0028] In addition, the adjustment component can also be a spring plate, which is arc-shaped, with one end hinged to the outer wall of the rotating shaft 4 and the other end hinged to the pressing arm 5.

[0029] like Figure 1 As shown, the pressing arm 5 has a "V" shaped structure. Setting the pressing arm 5 in a "V" shaped structure allows the force of the outer shell 1 to be applied more effectively to the pressing arm 5.

[0030] The opening of the outer casing 1 is equipped with a protective cloth 9 that encloses all the massage balls 7 inside the casing 1. Due to the series of mechanical structures inside the casing 1, the protective cloth 9 isolates the interior of the casing 1 from the outside to ensure practical safety. Because the protective cloth 9 is made of soft fabric, the massage balls 7 maintain a good massage effect even when separated by the protective cloth 9. During production, protrusions can also be set on the outer surface of the protective cloth 9, similar to an acupressure plate. During the massage process, the pressure generated by the spring 11 of the massage balls 7 acts on the protective cloth 9, and the protrusions on the protective cloth 9 stimulate acupoints during the rolling motion of the massage balls 7, thereby better promoting blood circulation.

[0031] The top of the outer casing 1 is equipped with a display screen 13, which can control the massage mode during massage. The outer casing 1 can be connected to a controller, which controls the speed and forward / reverse rotation of the motor 3, and distinguishes different modes according to the rotation of the motor 3.

[0032] In actual use, motor 3 drives shaft 4 to rotate, shaft 4 drives all pressing arms 5 to rotate, pressing arms 5 drive massage ball 7 to roll continuously on the human knee, and under the action of spring 11, massage ball 7 can roll in close contact with the human knee. Adjustment is completed by spring 11 driving sleeve 10 and fixed sleeve 2 to extend and retract, so that massage ball 7 can adapt to the undulations of the human knee surface and adjust to fit the knee for massage, thereby improving the massage effect.
