Description

Technical Field

[0001] This utility model belongs to the field of massage chair slide rail technology, and in particular relates to a slide rail sliding device for a massage chair. Background Technology

[0002] Massage is performed by using the rolling force and mechanical squeezing of a machine, mimicking human actions such as "kneading" and "pinching". The massage is performed by the movement of a mechanical arm, the squeezing of airbags, and the vibration of a massager. The sliding mechanism on the massage chair mainly consists of a slide rail, a slider, and a massage stick.

[0003] The travel distance of the slide rail is generally constant. However, since the sensations of people who need a massage are different, some need to adjust the contact point between the massage stick and the body. In particular, for tapping the back, some people need to tap into the back to different degrees. Therefore, in order to facilitate the adjustment of the different depths into the back by the massage stick, we propose a slide rail sliding device on the massage chair to solve the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a sliding rail device for a massage chair, which facilitates the adjustment of the depth to which the massage stick penetrates the back, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sliding rail device for a massage chair includes a sliding cylinder disposed on one side of the back panel. The bottom of the sliding cylinder is fixedly connected to the back panel through a support plate. A rotating rod is rotatably disposed on one side of the back panel through a bearing seat. A guide rod is slidably connected to the inner surface of the sliding cylinder. A cam is fixedly sleeved on the surface of the rotating rod. The guide rod and the cam are slidably fitted together. A threaded cylinder is rotatably connected to one side of the outer surface of the guide rod through a bearing cylinder. A massage stick is threadedly connected to the inner surface of the threaded cylinder. A limit rod is fixedly connected to the outer surface of the massage stick and located inside the guide rod. A limit groove is formed on the inner surface of the guide rod. The outer surface of the limit rod is slidably connected to the inner surface of the limit groove.

[0006] Preferably, there are multiple massage sticks, and a protrusion is fixedly connected to one side of each massage stick.

[0007] Preferably, a through hole is provided inside the back plate at a position corresponding to the massage stick, and the initial position of the protruding end face of the protrusion is flush with one end face of the massage stick.

[0008] Preferably, the rotation of the rotating rod causes the cam to lift or reset the guide rod.

[0009] Preferably, the outer surface of the back plate may be fitted with an elastic pad, and the connection between the elastic pad and the massage stick may be made by adhesive bonding.

[0010] Preferably, the lever is driven by the cooperation of gears and chains, and the driving force of the gears can be driven by a foot pedal.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the rotation of a rotating rod to drive the cam to rotate, thereby causing the guide rod to deviate in displacement on the inner surface of the sliding cylinder, which in turn causes the massage stick connected to the guide rod to move, thus tapping the user's back. When it is necessary to adjust the depth of tapping into the back, simply rotate the threaded cylinder, causing the threaded cylinder to rotate on the outer surface of the guide rod through the bearing cylinder. Under the rotation of the threaded cylinder, the massage stick is driven to move in a threaded manner, and is limited by the sliding of the limiting rod on the inner surface of the limiting groove, thereby causing the massage stick to move horizontally. Finally, the protrusion taps the back. By setting the above structure, it is convenient to adjust the different depths of the massage stick tapping into the back, thereby meeting the needs of the user.

[0013] 2. This utility model increases the number of contact points for massage by using multiple protrusions, thereby increasing the comfort of the massage.

[0014] 3. This utility model sets the initial position of the protruding end face of the protrusion to be flush with one end face of the massage stick, so that the protrusion does not rise above the end face of the back plate when not in use, which can meet the needs of users who do not need massage.

[0015] 4. The outer surface of this utility model can be fitted with an elastic pad, and the connection between the elastic pad and the massage stick can be made by adhesive bonding to reset the movement of the massage stick. Attached Figure Description

[0025] In the following description, embodiments of the sliding rail device on the massage chair of the present invention will be described with reference to the accompanying drawings.

[0026] Example 1:

[0027] Figure 1-6 This invention illustrates a sliding mechanism for a massage chair according to an embodiment of the present invention. The mechanism includes a sliding cylinder 2 disposed on one side of a back panel 1. The bottom of the sliding cylinder 2 is fixedly connected to the back panel 1 via a support plate 3. A rotating rod 5 is rotatably mounted on one side of the back panel 1 via a bearing seat. The rotating rod 5 is driven by a gear and a chain. The driving force of the gear can be provided by a foot pedal. A guide rod 4 is slidably connected to the inner surface of the sliding cylinder 2. Rotation of the rotating rod 5 causes a cam 6 to lift or reset the guide rod 4. The cam 6 is fixedly sleeved on the surface of the rotating rod 5, and the guide rod 4 and the cam 6 slide against each other. One side of the outer surface of the guide rod 4 is connected to a bearing cylinder 8. A threaded cylinder 9 is rotatably connected, and a massage stick 10 is threadedly connected to the inner surface of the threaded cylinder 9. An elastic pad 14 can be fitted on the outer surface of the back plate 1, and the connection between the elastic pad 14 and the massage stick 10 can be connected by adhesive. The massage stick 10 is reset by repositioning. A limiting rod 11 is fixedly connected to the outer surface of the massage stick 10 and inside the guide rod 4. A limiting groove 12 is opened on the inner surface of the guide rod 4, and the outer surface of the limiting rod 11 is slidably connected to the inner surface of the limiting groove 12.

[0028] The rotation of the rotating rod 5 drives the cam 6 to rotate, which in turn causes the guide rod 4 to deviate from its position on the inner surface of the sliding cylinder 2. This, in turn, moves the massage stick 10 connected to the guide rod 4, thereby tapping the user's back. When it is necessary to adjust the depth of the tapping, simply rotate the threaded cylinder 9, which rotates on the outer surface of the guide rod 4 via the bearing cylinder 8. The rotation of the threaded cylinder 9 causes the massage stick 10 to move in a threaded manner. The massage stick 10 is then limited by the sliding of the limiting rod 11 on the inner surface of the limiting groove 12, thus moving the massage stick 10 horizontally. Finally, the massage stick 10 taps the back through the protrusion 13. By setting up the above structure, it is convenient to adjust the depth of the massage stick tapping the back, thereby meeting the user's needs.

[0029] Example 2:

[0030] Figure 1-6 This invention illustrates a sliding mechanism for a massage chair according to an embodiment of the present invention. It includes a sliding cylinder 2 disposed on one side of a back panel 1. The bottom of the sliding cylinder 2 is fixedly connected to the back panel 1 via a support plate 3. A rotating rod 5 is rotatably mounted on one side of the back panel 1 via a bearing seat. A guide rod 4 is slidably connected to the inner surface of the sliding cylinder 2. A cam 6 is fixedly sleeved on the surface of the rotating rod 5, and the guide rod 4 and the cam 6 are slidably engaged. A threaded cylinder 9 is rotatably connected to one side of the outer surface of the guide rod 4 via a bearing cylinder 8. Massage rods 10 are threadedly connected to the inner surface of the threaded cylinder 9. Multiple massage rods 10 are present. A protrusion 13 is fixedly connected to one side of each massage rod 10. The back panel 1... An internal through hole 7 is provided at a position corresponding to the massage stick 10. The initial position of the convex end face of the protrusion 13 is flush with one end face of the massage stick 10. By using multiple protrusions 13, the number of massage contact points can be increased, thus increasing the comfort of the massage. By setting the initial position of the convex end face of the protrusion 13 to be flush with one end face of the massage stick 10, the protrusion 13 is not higher than the end face of the back plate 1 when not in use, which can meet the needs of users who do not need massage. A limiting rod 11 is fixedly connected to the outer surface of the massage stick 10 and inside the guide rod 4. A limiting groove 12 is provided on the inner surface of the guide rod 4. The outer surface of the limiting rod 11 is slidably connected to the inner surface of the limiting groove 12.

[0031] Working principle: When using this invention, the user can pedal the foot pedal, which drives the rotating rod 5 to rotate through the cooperation of the chain and gears. The rotation of the rotating rod 5 drives the cam 6 to rotate, thereby causing the guide rod 4 to deviate in displacement on the inner surface of the sliding cylinder 2. This, in turn, moves the massage stick 10 connected to the guide rod 4, thus tapping the user's back. When it is necessary to adjust the depth of tapping into the back, simply rotate the threaded cylinder 9, which rotates on the outer surface of the guide rod 4 through the bearing cylinder 8. Under the rotation of the threaded cylinder 9, the massage stick 10 moves in a threaded manner. The limiting rod 11 slides on the inner surface of the limiting groove 12 to limit the movement of the massage stick 10, thereby causing the massage stick 10 to move horizontally. Finally, the protrusion 13 taps the back, making it easy to adjust the depth of tapping into the back to meet the user's needs.
