Description

Technical Field

[0001] The present invention relates to the technical field of physical therapy devices, and in particular to a massage device for rehabilitation physical therapy. Background Art

[0002] Tui Na, also known as massage, is a traditional Chinese medical treatment method. It uses hands, elbows, feet or instruments to apply certain techniques to specific parts of the human body to regulate the body's physiological and pathological conditions. It is often used in human rehabilitation therapy because it can promote blood circulation, relieve pain, and improve muscle and joint functions.

[0003] The patent specification with the publication number CN115105386B discloses a meridian massage device for traditional Chinese medicine rehabilitation nursing. The invention comprises two support seats symmetrically distributed on the left and right, both of which are connected to a lifting sliding frame for sliding upward and downward sliding movement, both of which are connected to a rotating lead screw for rotation in the lifting sliding frame, and the sliding frame is threadedly connected to the rotating lead screw, the two sliding frames are symmetrically distributed, a crossbeam frame is connected between the two sliding frames, the two rotating lead screws are connected through a transmission mechanism, one of the rotating lead screws is connected to a driving motor fixedly connected to the lifting sliding frame, a massage frame is connected in the crossbeam frame, and a plurality of massagers connected end to end are connected in the massage frame; This scheme installs a crossbeam frame on a rotating screw, and installs multiple massage balls on the crossbeam frame. At the same time, a spring is arranged on the top of the crossbeam frame, and a spring is also installed at the bottom of the massage balls. All the massage balls are moved laterally as a whole through the movement of the rotating screw, and the massage balls are moved vertically through the vertically installed electric telescopic rod and two springs in the same vertical direction, thereby realizing the massage action. However, the disadvantage of this technical scheme is that the action mode of the massage balls under this scheme is always to repeatedly press a single point on the back of the therapist, and the pressing direction is always perpendicular to the back of the therapist. The horizontally moving rotating screw and the two springs do not change the massage mode of the massage balls' periodic single-point repeated pressing. However, the actual massage action is a circumferential oblique push on a certain area of ​​the therapist's back, that is, the massage device cannot effectively simulate the actual massage action. Summary of the invention

[0013] Beneficial effects of the present invention: 1. In the present invention, a rack, a limit bar and a slot are arranged in the shell, and the driving assembly is installed in the shell. A motor 1 is installed on the bottom plate of the driving assembly, and the motor 1 and the multi-gear are used to transmit the power to the rack. A motor 2 is installed on the other side of the bottom plate, and the motor 2 is transmitted to the rotating base through a transmission gear set. A bevel cylinder is installed on the top of the rotating base, and an oblique limit ring groove is arranged in the middle of the bevel cylinder. A push plate is installed in the limit ring groove, and massage balls are installed on both sides of the top of the push plate. When in use, the motor 1 is transmitted to the rack by means of a worm gear and a gear set, and each massage ball can be moved as a whole along the rack. At the same time, the motor 2 is transmitted to the bevel cylinder by means of a transmission gear set, and the massage ball can move vertically along the overall moving direction, thereby realizing comprehensive massage of the back area of ​​the therapist; The present invention utilizes motor 2 and a transmission gear group to drive the rotating base to rotate, and the side rotating shaft at the top of the rotating base drives the inclined plane cylinder to perform circular motion. During the rotation process, one end of the push plate installed on the limiting ring groove is limited by the limiting seat fixed on the top cover, and the massage balls installed on the side of the other end cause the movement height to change back and forth due to the inclined surface. At the same time, because the push plate rotates sideways along the inclination direction of the axis center line of the inclined plane cylinder during movement, the massage balls installed on the push plate perform circular motion in the horizontal direction at the same time, and the vertical and horizontal motions of the massage balls are performed simultaneously. With the spring connection between the massage ball and the push plate, a certain area of ​​the back of the therapist is massaged with regular changes in weight and oblique pushing along the rotation direction of the massage ball. This technical means can make the movement of the massage ball closer to the actual manual massage movement during massage, thereby improving the massage therapy effect of the device and avoiding the cyclic pressing phenomenon perpendicular to a single point on the back of the therapist.

[0014] 2. In the present invention, a worm and a worm wheel are driven by a motor to transmit the gears, and the transmission is transmitted to the rack so that the driving assembly can move in the shell. At the same time, a motor is installed on the other side of the driving assembly, and the massage ball is driven to move by the transmission of the worm and the worm wheel as well as the transmission gear set. Since the transmission of the two worm wheels is vertical reversing transmission, the overall structure of the physiotherapy device is assembled and packaged between the bottom plate and the top cover. Compared with the vertical structure of the output end of the existing device using the cylinder, the overall thickness of the device is much smaller than that of the existing device due to the reversing transmission during operation. This technical means can be packaged in the chair back shell structure by virtue of its more compact structure and thinner operating thickness. Its purpose is to improve the convenience of the device when used, avoid its operation occupying a large space, resulting in it being only used as a physiotherapy facility of a physiotherapy institution, so that it has a wider range of application scenarios.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, a massage device for rehabilitation therapy comprises a shell 1, a driving assembly 2 is installed inside the shell 1, the driving assembly 2 reciprocates vertically inside the shell 1, a motor 2 3 is installed on one side of the driving assembly 2, a transmission gear set 4 is arranged on both sides of the output end of the motor 2 3, a rotating base 12 is arranged on one side of the transmission gear set 4, a bevel cylinder 15 is installed on the top of the rotating base 12, an oblique limiting ring groove 16 is arranged in the middle of the bevel cylinder 15, a top cover 23 is installed on the top of the driving assembly 2, a push plate 18 is installed between the top cover 23 and the limiting ring groove 16, two massage balls 5 are installed on both sides of the top of the push plate 18, and the massage balls 5 make circular motion in the horizontal direction while reciprocating vertically; It should be noted that the shell 1 is long and narrow, with a cavity set on one side, and five buckles 6 installed on one side of the cavity. The outer shell 1 can be installed on the outside of the device through each buckle 6 to connect with the seat backrest. The user can then perform rehabilitation therapy and massage by sitting on the seat and leaning against the device.

[0020] like Figure 2 and Figure 3 As shown, a limit bar 7 is provided in the middle of the shell 1, a slot 8 is provided on the side of the buckle 6 close to the limit bar 7, a rack 9 is fixedly connected to the side of the inner side of the shell 1 away from the slot 8, and the driving component 2 includes a bottom plate 201 installed inside the shell 1, the middle of the bottom surface of the bottom plate 201 is slidably connected to the limit bar 7, and a side bar 10 is provided on the side of the bottom plate 201, and the side bar 10 is clamped between the slots 8, that is, when the driving component 2 moves, the side bar 10 slides between the slots 8; The driving assembly 2 further includes a motor 1 202 mounted on one side of the top of the bottom plate 201, a worm 1 203 is mounted on the output end of the motor 1 202, one side of the worm 1 203 is meshed with a worm wheel 1 204, the bottom surface of the worm wheel 1 204 is fixedly connected to a gear 1 205, one side of the gear 1 205 is meshed with a gear 2 206, one side of the gear 206 is meshed with a gear 3 207, and the gear 3 207 is meshed with the rack 9; It should be noted that after the motor 1 202 is driven, the worm 1 203 at the output end is driven to rotate, the worm 1 203 drives the gear 1 205 at the bottom to rotate, the gear 1 205 drives the gear 2 206 to rotate, and the gear 2 206 drives the gear 3 207 to rotate. Since the gear 3 207 is meshed with the rack 9, the rotation of the gear 3 207 drives the bottom plate 201 to move along the rack 9, thereby controlling the rotation direction of the motor 1 202 and realizing the vertical reciprocating motion function of the driving component 2 in the housing 1. Specifically, during the reciprocating motion, due to the rotation of one side of the bottom plate 201, the bottom plate 201 is rotated. The side strips 10 are limited and clamped between the slots 8, and the moving direction of the bottom plate 201 is limited by the limit strips 7 inside the shell 1, so the stability of the driving component 2 during operation can be guaranteed, and the massage balls 5 installed together on the bottom plate 201 can move back and forth stably. The purpose is to ensure that the massage balls 5 can avoid vibration interference during the movement of the device when they move back and forth during massage, thereby improving the comfort during massage, through the limited movement of the limit strips 7, the slots 8 and the rack 9, in conjunction with the transmission of multiple gears, when the device is used as a part of a physiotherapy chair.

[0021] like Figures 4 to 6 As shown, the motor 2 3 is installed in the middle of one side of the bottom plate 201 away from the motor 1 202, and its output end is fixedly connected to the worm 2 11, and the transmission gear set 4 is installed on both sides of the worm 2 11. The transmission gear set 4 includes a worm wheel 2 401 meshing with the worm 2 11, and the bottom surface of the worm wheel 2 401 is fixedly connected to the gear 4 402, and the gear 402 meshes with the gear 5 403. The rotating base 12 is fixedly connected to the top of the gear 5 403; A central axis hole is provided in the middle of the top of the rotating base 12, and a side rotating shaft 13 is fixedly connected to one side. A side rotating cylinder 14 is installed on the top of the rotating base 12. A connecting hole is provided on the side rotating cylinder 14 to match the central axis hole. The side rotating shaft 13 is installed between the rotating base 12 and the side rotating cylinder 14. It should be noted that a connecting shaft (not shown) is installed between the central axis hole and the connecting hole of the rotating base 12 and the side rotating cylinder 14, which is used to connect the rotating base 12 and the side rotating shaft 13; after the motor 23 is started, it drives the worm 2 11 to rotate, and the worm 2 11 drives the worm wheel 2 401 to rotate, and the worm wheel 2 401 is transmitted to the gear 5 403, and then the rotating base 12 starts to rotate. During the rotation of the rotating base 12, the side rotating shaft 13 connected thereto drives the side rotating cylinder 14 to rotate.

[0022] The inclined cylinder 15 is fixedly connected to the top of the side rotating cylinder 14, a snap ring 17 is installed on the outer side of the limiting ring groove 16, and the central through hole of the push plate 18 is connected to the snap ring 17. A spring 19 is fixedly connected between the bottom surface of the massage ball 5 and the push plate 18. Guide rods 20 are arranged on both sides of the bottom surface of the massage ball 5. The top of the push plate 18 is adapted to the guide rod 20 and fixedly connected to the guide cylinder 21. A limiting rod 22 is arranged on one side of the push plate 18. A top cover 23 is fixedly connected to the top of the bottom plate 201. The top cover 23 is fixedly connected to a limiting seat 24 on one side of the limiting rod 22. A limiting strip hole 25 is arranged in the middle of the limiting seat 24, and one end of the limiting rod 22 is limitedly inserted in the limiting strip hole 25. It should be noted that the side rotating shaft 13 drives the side rotating drum 14 to rotate under the drive of the motor 23. When the side rotating drum 14 rotates, the inclined drum 15 fixedly connected to the top end thereof rotates together. Figure 6 ) Since the limiting ring groove 16 in the middle part has an angle with the horizontal plane, the snap ring 17 in the limiting ring groove 16 is used to connect with the push plate 18, wherein the snap ring 17 and the limiting ring groove 16 are fixedly connected, and the snap ring 17 is engaged with the through hole in the middle part of the push plate 18, and its function is to limit the push plate 18 while maintaining relative rotation with the push plate 18. During the movement of the push plate 18, one end of the push plate 18 will not rotate synchronously with the rotation of the snap ring 17 due to the connection between the limiting rod 22 and the limiting bar hole 25. Therefore, when it is limited by the limiting ring groove 16 and the limiting seat 24 together, it will change in height with the rotation of the limiting ring groove 16; Specifically, when the lower position of the limiting ring groove 16 is close to the limiting seat 24, the upper position of the limiting ring groove 16 is below the massage ball 5, and the massage ball 5 is in a high position. When the upper position of the limiting ring groove 16 is close to the limiting seat 24, the lower position of the limiting ring groove 16 is below the massage ball 5, and the massage ball 5 is in a low position. Since the height of the massage ball 5 is changed, in addition, since the massage ball 5 is not coaxial with the axis of the inclined cylinder 15 when the height is changed, it will make a circular motion in the horizontal direction while the height changes, and the vertical reciprocating motion and the horizontal circular motion occur synchronously. In addition, since a spring 19 is installed between the bottom surface of the massage ball 5 and the push plate 18, the spring 19 is extended when the massage ball 5 is in a low position, and the spring 19 is compressed when the massage ball 5 is in a high position, thereby ensuring that the device is always in contact with the back of the therapist. It can be seen that when the motor 1 202 moves to a certain place, the motor 2 3 rotates to drive the massage balls 5 on both sides to massage, so as to synchronously massage both sides of the therapist's back, and during the massage, the massage ball 5 can perform a switching push from light to heavy on a certain area of ​​the therapist's back. The horizontal rotation of the massage ball 5 and the closest point to the therapist's back will frequently change and change periodically due to the lateral periodic rotation. At the same time, due to the annular push, the massage of this part of the area and the thrust direction of the therapist's back are oblique, that is, the patient's back is pushed obliquely with regular light and heavy changes within the annular range, which is consistent with the actual action of manual massage. It is essentially different from the vertical repeated pressing of the point position on the therapist's back in the prior art, and has better anthropomorphic performance and massage therapy experience.

[0023] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
