Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, specifically to an adjustable track inside a massage chair. Background Technology

[0002] A massage chair is a piece of furniture that provides massage functions. It typically uses electric, pneumatic, or manual methods for massage and usually has multiple massage functions and different massage techniques, such as kneading, rubbing, tapping, and massaging. These can help relieve muscle fatigue, reduce body tension, promote blood circulation, and relieve stress. During the operation of a massage chair, the internal massage heads need to move back and forth within the track to achieve the purpose of massage. Therefore, the track is an important component of a massage chair.

[0003] In the prior art, Chinese patent publication number CN112450635A discloses an integrated track and track assembly for a massage chair. The track includes a track section and a rack section, wherein the track section and the rack section are integrally molded curved structures made of plastic. The track cross-section has parallel upper and lower edges, as well as a vertical wall connecting the upper and lower edges. The rack section is located on the outer side of the lower edge, and the track section is formed between the inner side of the lower edge and the vertical wall. The track assembly also includes a channel steel that matches the curved shape of the track. The channel steel is used to lock the track and plays a role in positioning and bearing weight, integrating the rack and the track section into one piece. It is molded in one piece of plastic material to ensure the precision of the fit between the curved rack and the track, so that the massage mechanism running on it moves more smoothly and reduces noise caused by gaps.

[0004] The aforementioned tracks work together to reduce noise. However, in actual use, the distance between the two tracks corresponds to the distance between the massage heads on both sides. Different people have different body shapes, so the distance between the massage heads on the left and right sides is also different. The aforementioned device cannot adjust the distance, so it cannot adapt to the massage needs of different people and cannot achieve the best massage effect. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable track inside a massage chair to solve the problem of the inability to adjust the spacing mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable track inside a massage chair, comprising two curved mounting tracks, and further comprising:

[0007] The mounting track is installed inside the massage chair using an upper fixed frame, a middle fixed frame, and a lower fixed frame located on the back.

[0018] Furthermore, the controller can be activated by different people to make the telescopic cylinder work, which in turn moves the connecting block up and down. During the movement of the connecting block, the connecting rod drives the adjusting rod to rotate, thereby causing the adjusting rod to pull or push the installation rails on the left and right sides to change their positions, thus achieving the purpose of adjusting the spacing.

[0019] Furthermore, during the movement of the mounting track, the limiting slider at the rear slides accordingly within the adjusting groove to achieve the purpose of limiting. At the same time, the friction rollers on the upper and lower sides of the limiting slider can reduce the frictional resistance during sliding.

[0020] 2. When the massage roller moves to the top, the sponge brush and the temporary sponge squeeze each other, thereby squeezing the lubricant in the temporary sponge into the sponge brush, achieving the purpose of automatic lubrication. The lubricant in the temporary sponge is replenished by the storage box. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figures 1-3To address the problem of traditional tracks being unable to adjust their spacing during use, this embodiment provides the following technical solution: The spacing is adjusted by pulling or pushing the mounting track 1 left or right using an adjustment mechanism. Specifically, it discloses two curved mounting tracks 1. The mounting tracks 1 are installed inside the massage chair using an upper fixing frame 2, a middle fixing frame 3, and a lower fixing frame 4 located on their backs. Massage rollers 5 for massaging the back of the user are slidably mounted on the front side of the mounting tracks 1. An adjustment mechanism for adjusting the spacing between the two mounting tracks 1 is located below the middle fixing frame 3. The adjustment mechanism includes components fixedly mounted on the middle fixing frame 3. The controller 11 is located in the middle of the front outer surface of the fixed frame 3. An automatic lubrication mechanism for adding lubricating oil to the upper end of the mounting rail 1 is provided for maintenance. The automatic lubrication mechanism includes a storage box 14 for storing lubricating oil. The adjustment mechanism also includes an adjustment rod 7 rotatably installed between the two mounting rails 1, and the two adjustment rods 7 rotate crosswise. A connecting rod 8 for pulling the adjustment rod 7 is rotatably installed above the adjustment rod 7, and the upper end of the connecting rod 8 is rotatably installed between the connecting rod 8 and the connecting block 9. A telescopic cylinder 10 is fixedly installed between the connecting block 9 and the controller 11, and the connecting block 9 moves up and down through the telescopic cylinder 10.

[0030] During installation, the upper fixed frame 2, middle fixed frame 3, and lower fixed frame 4 are first fixed inside the massage chair using bolts. Then, the two mounting tracks 1 are symmetrically installed on the front of the upper fixed frame 2, middle fixed frame 3, and lower fixed frame 4. During massage, the massage rollers 5 move up and down within the mounting tracks 1 to massage the back. When facing different people, the controller 11 activates the telescopic cylinder 10, causing the telescopic cylinder 10 to drive the connecting block 9 to move up and down. During the movement of the connecting block 9, the connecting rod 8 rotates, thereby driving the adjusting rod 7 to rotate. This allows the adjusting rod 7 to push or pull the mounting tracks 1 on the left and right sides to change their positions, ultimately achieving the purpose of adjusting the spacing to suit different people.

[0031] Example 2: Please refer to Figure 4 In order to reduce the frictional resistance when adjusting the installation track 1, this embodiment provides the following technical solution, which specifically discloses that: the upper fixed frame 2, the middle fixed frame 3 and the lower fixed frame 4 are all provided with adjustment grooves 6 on their front outer surfaces, and the rear outer surface of the installation track 1 is fixedly installed with a limit slider 12, and the limit slider 12 and the adjustment groove 6 form a left and right sliding structure, and friction rollers 13 for reducing friction are rotatably installed on the upper and lower sides of the limit slider 12.

[0032] When the installation track 1 moves, the limiting slider 12 fixedly installed on its rear outer surface slides accordingly in the adjusting groove 6 to achieve the purpose of limiting and prevent the installation track 1 from tilting. At the same time, the friction rollers 13 on the upper and lower sides of the limiting slider 12 rotate to reduce the frictional resistance during sliding.

[0033] Example 3: Please refer to Figure 5 and Figure 6 In order to solve the problem that it is inconvenient to add lubricating oil for maintenance during the use of traditional tracks, this embodiment provides the following technical solution: setting up an automatic lubrication mechanism, specifically disclosing that: a filling tube 15 extending to the outside of the massage chair is fixedly installed on the upper end of the storage box 14, and a temporary sponge 16 is fixedly installed inside the upper end of the mounting track 1. The temporary sponge 16 is connected to the storage box 14 through a connecting tube 17, and the position of the temporary sponge 16 corresponds vertically to the position of the sponge brush 18. The sponge brush 18 is fixedly installed above the slider at the rear end of the massage roller 5.

[0034] When the mounting track 1 needs lubrication, first move the massage roller 5 to the top (the massage roller 5 will not move to the top during normal use), so that the sponge brush 18 connected to the massage roller 5 squeezes the temporary sponge 16, thereby squeezing the lubricant in the temporary sponge 16 into the sponge brush 18 (the lubricant in the storage box 14 flows into the temporary sponge 16 through the connecting pipe 17, and can be added to the storage box 14 through the filling pipe 15). Then the sponge brush 18 moves with the massage roller 5, applying the lubricant to all parts of the mounting track 1 to achieve automatic lubrication.
