Description

Technical Field

[0001] This utility model belongs to the field of support technology, and in particular relates to an adaptive support structure for a massage bed. Background Technology

[0002] Currently, massage beds on the market generally suffer from insufficient support. Traditional massage beds typically have fixed leg supports or simple hinged designs, offering limited adjustment range and failing to automatically adapt to the needs of users with different body types. Rigid support structures result in poor comfort during position changes, uneven pressure distribution, and easy wear and tear on mechanical parts, leading to a shorter lifespan and making them unsuitable for high-frequency use in commercial settings. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an adaptive support structure for a massage bed.

[0004] To achieve the above objectives, the technical solution adopted is: An adaptive support structure for a massage bed includes a main bed frame. One end of the main bed frame is connected to a leg support. The leg support can reciprocate in the horizontal direction relative to the main bed frame, moving away from or towards the main bed frame to achieve opening and closing. The end of the leg support away from the main bed frame is rotatably connected to a support assembly. The support assembly includes a first roller, a torsion spring, and a housing. One end of the housing is rotatably connected to the leg support, the first roller is connected to the other end of the housing, and the torsion spring is located inside the housing.

[0005] The beneficial effects of adopting the above technical solution are as follows: the horizontal movement of the leg support adapts to different user body shapes, expanding the scope of use; the torsion spring-roller combination structure realizes dynamic adjustment of support force. When the user changes position, the torsion spring absorbs the impact through elastic deformation, and the roller assists in fine-tuning the position, improving comfort.

[0006] Based on the above technical solution, the present invention can be further improved as follows: Preferably, the main bed body and the leg support are connected by a swing arm.

[0007] The beneficial effect of adopting the above-mentioned preferred technical solution is that the main bed body and the leg support are hinged by a swing arm, and the swing arm mechanism converts the horizontal movement into an arc trajectory including three states: open, upright and closed, thus avoiding the jamming problem of the linear guide rail.

[0008] Preferably, the lower end of the swing arm is rotatably connected to the main bed body, and the upper end of the swing arm is rotatably connected to a sliding frame, which is slidably connected to the leg support.

[0009] The advantages of adopting the above-mentioned preferred technical solution are: the sliding connection between the sliding frame and the leg support allows the leg support to remain stable during movement, reduces friction and jamming, and improves the smoothness of adjustment.

[0010] Preferably, the inner side of the leg support is provided with a slide rail, and the two ends of the sliding frame are provided with second rollers. The second rollers roll along the slide rail to realize the sliding connection between the sliding frame and the leg support.

[0011] The advantages of adopting the above-mentioned preferred technical solution are: the cooperative design of the slide rail and roller further reduces sliding friction, making the movement of the leg support easier and smoother, which is suitable for application scenarios that require frequent adjustments.

[0012] Preferably, the torsion spring includes a spring coil and two lever arms connected to both ends of the spring coil. One lever arm of the torsion spring is connected to the inner wall of the housing, and the other lever arm of the torsion spring is connected to the leg support.

[0013] The beneficial effects of adopting the above-mentioned preferred technical solution are that the torsion spring stores energy when the user presses down and releases energy when the user lifts up, thus maintaining the balance of the supporting force.

[0014] Preferably, the support assembly is connected to the leg support via a connector.

[0015] More preferably, the connector includes a connecting rod that passes through both ends of the housing, and the spring coil of the torsion spring is sleeved around the outer periphery of the connecting rod.

[0016] The beneficial effects of adopting the above-mentioned preferred technical solution are as follows: the connecting rod serves as the rotation axis, and the torsion spring and the housing can rotate relative to the connecting parts, thereby changing the tilt angle of the housing.

[0017] Preferably, the connector further includes a connecting plate, and the connecting plate has hanging ears at both ends. The hanging ears at both ends are respectively located at both ends of the outer side of the housing, and the connecting rod passes through the housing and connects to the hanging ears.

[0018] Preferably, the upper part of the housing is provided with a front limiting protrusion and a rear limiting protrusion.

[0019] More preferably, the front limiting protrusion is located on the side of the housing near the main bed, and the rear limiting protrusion is located at the top of the housing.

[0020] The beneficial effects of adopting the above-mentioned preferred technical solution are as follows: the front limiting protrusion and the rear limiting protrusion are used to limit the rotation angle of the shell relative to the leg support, and prevent excessive torsion from causing plastic deformation of the torsion spring. The front limiting protrusion is located on the side of the shell close to the main bed, and is used to cooperate with the connecting plate to limit the tilt angle of the shell when the leg support is away from the main bed, i.e., when it is open. The rear limiting protrusion is located at the top of the shell, and is used to cooperate with the connecting plate to limit the tilt angle of the shell when the leg support is close to the main bed, i.e., when it is closed.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves three optimizations through a horizontally movable leg support and a roller support assembly with torsion springs: 1) horizontal telescopic adaptation to different body shapes; 2) automatic adjustment of support force by the torsion springs; 3) rollers assist in fine-tuning of body position. The rollers can contact the ground to support the weight of the legs and feet. The improved swing arm mechanism and limiting protrusion make the structure more stable and reliable. The whole structure has the characteristics of flexible adjustment, comfortable use and long service life, and is particularly suitable for commercial massage scenarios. Attached Figure Description
