[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The lumbar support assembly of a medical bed shown includes a bed board 1, with support legs 2 installed at the bottom of the bed board 1. A cavity 3 is reserved inside the bed board 1, and a light rod 4 is fixedly connected to the inner wall of the cavity 3. A square block 5 is slidably connected to the outer ring of the light rod 4 through a sliding limiting assembly 7. The square block 5 is restricted to the light rod 4 through a limiting assembly 8, and a lumbar support pad 6 is fixedly connected to the outer wall of the square block 5.

[0025] During use, the position of the lumbar support pad 6 can be moved by sliding the square block 5, making it convenient for patients of different heights to use. At the same time, the position of the square block 5 and the lumbar support pad 6 within the narrow area of ​​the cavity 3 is limited by the sliding limiting component 7, preventing the lumbar support pad 6 from shifting during use. In addition, different patients have different preferences, and the two lumbar support pads 6 are available in different firmness levels. The firmness level can be changed by flipping the lumbar support pad 6. The angle of the flipped lumbar support pad 6 is limited by the limiting component 8, which facilitates the subsequent movement of the lumbar support pad 6.

[0026] The cavity 3 is T-shaped, and the inner wall of the narrow cavity 3 is attached to the outer wall of the square block 5 and forms a sliding connection. The inner square area of ​​the cavity 3 is rotatably connected to the lumbar support pad 6, ensuring that the square block 5 and the lumbar support pad 6 can move and flip smoothly.

[0027] Two lumbar support pads 6 are provided, and the two lumbar support pads 6 are fixedly connected to the opposite side walls of the square block 5. The opposite straight surfaces of the two lumbar support pads 6 can be attached to the surface of the bed board 1 to achieve a sliding connection, which facilitates the replacement and use of the lumbar support pads 6.

[0028] Different patients have different preferences. The two lumbar support pads are 6-point softness. You can change the softness by flipping the lumbar support pads 6-point.

[0029] The sliding limit component 7 includes a groove 701 pre-set inside the square block 5. Two grooves 701 are symmetrically arranged inside the square block 5 with reference to the central axis of the square block 5. A slider 702 is movably connected inside the groove 701 by a spring 704. The slider 702 is in active engagement with a slot 705. The slot 705 is connected to the narrow cavity of the cavity 3. The ends of the slider 702 that match the slot 705 have inclined surfaces 703 with opposite inclination directions on both sides. The inclination of the inclined surface 703 is 35 degrees. During the movement of the square block 5, the corner of the narrow area of ​​the cavity 3 abuts against the inclined surface 703, thereby squeezing the slider 702 into the groove 701, facilitating the movement of the square block 5. Subsequently, the spring 704 pushes the slider 702 to move, causing the slider 702 to match the slot 705, ensuring that the position of the lumbar support pad 6 is fixed.

[0030] There are several slots 705, which are evenly spaced and arranged in a straight line. The slots 705 are divided into upper and lower groups. After the square block 5 slides, it is limited to restrict the position of the lumbar support pad 6. In this way, when the lumbar support pad 6 is flipped, the square block 5 is flipped synchronously, and the slider 702 can still match the slots 705 set in the lower row to achieve the position restriction of the lumbar support pad 6.

[0031] The limiting component 8 includes a vertical groove 801 pre-set inside the square block 5. The vertical groove 801 is connected to the through hole through which the light rod 4 passes inside the square block 5. The inside of the vertical groove 801 is movably connected to the locking rod 803 by a spring 802. The top of the locking rod 803 is fixedly connected to a ball end 804, which matches the locking groove 805 reserved inside the light rod 4. There are two slots 805, which are symmetrically arranged with reference to the central axis of the rod 4. The inner wall of the slot 805 is attached to the arc-shaped outer wall of the ball end 804 to achieve a sliding connection. In this way, when the lumbar support pad 6 flips and drives the square block 5 to flip, the ball end 804 can be separated from the slot 805 in the moving state, so as not to affect the flipping operation of the square block 5. At the same time, the subsequent spring 802 applies pressure to cause the locking rod 803 to drive the ball end 804 to move and match the corresponding position of the slot 805, which facilitates the position limitation after the lumbar support pad 6 rotates. The lumbar support pad 6 can be moved and used after being limited.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
