Description

Technical Field

[0001] This utility model belongs to the field of health and wellness, and specifically relates to a dual-track single-drive massage chair frame. Background Technology

[0002] In modern society, people's pursuit of health and quality of life is constantly improving. As a device that can provide a comfortable massage experience and relieve physical fatigue, massage chairs have received increasing attention. With the continuous advancement of technology and people's increasing demands for massage chair performance, dual-track single-drive massage chair frames have emerged. This design combines the stability of dual tracks with the simplicity of single drives, ensuring smooth and reliable operation of the massage chair while reducing production costs and maintenance difficulties.

[0003] Existing equipment has drawbacks: users cannot easily adjust to a suitable position according to their preferences and needs, resulting in an uneven distribution of body weight, causing greater pressure on certain parts of the body and affecting the massage effect. Additionally, the footrest angle may be unsuitable, and the footrest length may be inconsistent with different users' leg lengths, leading to user discomfort. Therefore, we have proposed a dual-track single-drive massage chair frame. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-track single-drive massage chair frame. By using a threaded rod and a sliding plate, it solves the problems that users may find it inconvenient to adjust to a suitable position according to their own preferences and needs, resulting in an incomplete distribution of body weight, causing greater pressure on certain parts of the body and affecting the massage effect. At the same time, the footrest may be at an unsuitable angle, and the footrest may be of different lengths depending on the user's leg length, leading to user discomfort.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dual-track single-drive massage chair frame, comprising a base, with several fixed supports fixedly connected to the inner wall of the base, a rotating shaft rotatably connected to the inner wall of each fixed support, a fixed plate fixedly connected to the outer wall of the rotating shaft, several seat frames fixedly connected to the outer wall of the fixed plate, a support plate fixedly connected to the outer wall of each seat frame near the base, and a seat fixedly connected to the outer wall of each seat frame. An adjustment mechanism is provided at the top of the base, the adjustment mechanism including a fixed frame fixedly connected to the base, several circular holes formed in the inner wall of the fixed frame, a rotating rod rotatably connected to the inner wall of the fixed frame, and an extension mechanism provided on the outer wall of the seat, the extension mechanism including a limiting frame fixedly connected to the seat, a rolling rod rotatably connected to the inner wall of the limiting frame, and a leg rest fixedly connected to the outer wall of the rolling rod.

[0007] By using the above technical solution, the seat frame is fixed with a fixing plate, so the seat frame will not wobble during use, making it more stable.

[0008] Furthermore, a turntable is fixedly connected to the outer wall of the rotating rod on the side away from the rolling rod, an insert rod is slidably connected to the inner wall of the turntable, and a gripping rod is fixedly connected to the outer wall of the turntable on the side away from the rolling rod.

[0009] The above technical solution uses a plug rod to fix the turntable in place when it is not needed to rotate, thus locking the turntable in place.

[0010] Furthermore, a universal joint is fixedly connected to the outer wall of the rotating rod on the side away from the turntable, a threaded pipe is fixedly connected to the outer wall of the universal joint on the side away from the turntable, a threaded rod is threadedly connected to the inner wall of the threaded pipe, a fixing block is fixedly connected to the outer wall of the threaded rod on the side away from the turntable, and a joint shaft is rotatably connected to the inner wall of the fixing block.

[0011] The above technical solution uses a universal joint to drive the threaded pipe. Even when the angle changes as the threaded pipe rotates, the universal joint can still drive the threaded pipe to rotate.

[0012] Furthermore, a support frame is fixedly connected to the bottom of the seat frame, the support frame is fixedly connected to the joint shaft, and a sliding rod is fixedly connected to the end of each support frame. A limiting plate is fixedly connected to the outer wall of one end of each fixed bracket near the leg rest, and the sliding rod is slidably connected to the limiting plate. A sliding rod is slidably connected to the inner wall of each seat frame.

[0013] The above technical solution ensures that the seat frame moves along a track by using a limiting plate, preventing deviation or excessive movement.

[0014] Furthermore, a massage plate is fixedly connected to the top of the sliding rod, a plurality of pivots are fixedly connected to the top of the massage plate, a massage frame is rotatably connected to the outer wall of the plurality of pivots, a plurality of rubber wheels are rotatably connected to the outer wall of the plurality of massage frames, and a rack is fixedly connected to the outer wall of the plurality of seat frames.

[0015] The above technical solution uses rubber wheels to massage the user, and the rubber wheels can move according to the body's contours.

[0016] Furthermore, a number of dampers are fixedly connected to the top of the massage plate, and springs are fixedly connected to the outer walls of the dampers. A support bracket is fixedly connected to the bottom of the massage plate, and a motor is fixedly connected to the inner wall of the support bracket. A drive shaft is fixedly connected to the bottom output end of the motor via a coupling.

[0017] The above technical solution uses a support bracket to fix the motor in place, preventing it from shaking when it moves.

[0018] Furthermore, a gear is fixedly connected to the outer wall of the transmission shaft on the side away from the motor, and several reinforcing plates are fixedly connected to the bottom of the massage plate. A transmission rod is rotatably connected to the inner wall of the reinforcing plate, and several spur gears are fixedly connected to the outer wall of the transmission rod. The spur gears mesh with the gears, and the spur gears mesh with the rack.

[0019] The above technical solution uses a gear to drive a spur gear to rotate, and when the spur gear rotates, it drives the massage plate to move through a rack.

[0020] Furthermore, a triangular plate is fixedly connected to the outer wall of the support frame near the leg rest. The inner wall of the triangular plate has several slots. A sliding plate is slidably connected to the inner wall of the leg rest. The inner wall of the sliding plate has several holes. A crossbar is slidably connected to the inner wall of the leg rest. A second joint shaft is fixedly connected to the outer wall of the leg rest near the grip bar. A support rod is rotatably connected to the outer wall of the second joint shaft.

[0021] The above technical solution allows for the extension of the footrest using a skateboard, enabling adjustments to the appropriate length for different users.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model incorporates a threaded rod. When the turntable rotates, it drives the rotating rod to rotate, which in turn drives the universal joint to rotate, which in turn drives the threaded tube to rotate, which in turn drives the threaded rod to rotate. As the threaded rod rotates, it moves out of the threaded tube. The movement of the threaded rod causes the fixed block to move, which in turn drives the joint axis to move, which in turn drives the support frame to move. The support frame then moves along a track within the limiting plate via a sliding rod, which in turn drives the seat frame to move. Once the seat frame is in the appropriate position, the insertion rod is inserted into the round hole for fixation. This allows the user to adjust to the most comfortable posture according to their preferences and needs. Changes in angle allow for better distribution of body weight, reducing localized pressure and enabling complete relaxation during the massage.

[0024] 2. This utility model incorporates a sliding plate that allows the leg rest to be raised. Raising the leg rest causes the rolling rod to rotate, and the support rod moves as the leg rest is raised. When the leg rest is raised to a suitable angle, the support rod can be inserted into the corresponding slot on the triangular plate, maintaining the leg rest at a fixed angle. Simultaneously, the sliding plate can be pulled out, moving within the leg rest and extending it. After extending to a suitable position, the crossbar is inserted into the hole for fixation. This improves comfort, allowing the user's legs to be straightened, making the user more comfortable. Furthermore, the length can be adjusted for different users, ensuring comfortable rest for all.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

As the support frame 212 moves, it moves along a track within the limiting plate 214 via the slide rod 213. This movement of the support frame 212 also moves the seat frame 104. After the seat frame 104 reaches the appropriate position, the insertion rod 205 is inserted into the round hole 202 for fixation. Simultaneously, the leg rest 305 can be lifted. When the leg support 305 is raised, the roller 304 will rotate. When the leg support 305 is raised, the support rod 310 will move. When the leg support 305 is raised to a suitable angle, the support rod 310 can be put into the corresponding slot 302 on the triangle plate 301, so that the leg support 305 maintains an angle and does not change angle. At the same time, the slide plate 306 can be pulled out. When the slide plate 306 is pulled out, it will move inside the leg support 305 and be extended. After being extended to a suitable position, the crossbar 308 is inserted into the hole 307 for fixation.
