Detailed Implementation

[0025] 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.

[0026] Please see Figures 1 to 6This utility model provides a technical solution: an adjustable bracket, comprising: a support base 1; a support base 2 rotatably disposed on the top of the support base 1, and an adjusting screw 14 rotatably disposed inside the support base 2; an inner adjusting support plate 3 installed on the outside of the adjusting screw 14, the inner adjusting support plate 3 being slidably connected to the support base 2, and a top support platform 4 being bolted to the top of the inner adjusting support plate 3; a fixed support platform 5 slidably disposed inside the top support platform 4, and a leg support 7 being bolted to the top of the fixed support platform 5, with a limiting side plate 6 fixedly connected to one side of the fixed support platform 5. The limiting side plate 6 is slidably connected to the top support platform 4; the rotation adjustment part is placed inside the support base 2, and the adjusting screw 14 is connected to the rotation adjustment part; the bottom fixing box 18 is installed at the bottom of the support base 1 by bolts, and the inner rotating round seat 19 is rotatably arranged inside the bottom fixing box 18. The inner rotating round seat 19 is rotatably connected to the support base 1, and the top of the inner rotating round seat 19 is fixedly connected to the support base 2; the first card plate 21 is slidably arranged inside the bottom fixing box 18, and multiple side limiting slots 20 that cooperate with the first card plate 21 are equidistantly opened on the outer side of the inner rotating round seat 19.

[0027] It should be noted that in this embodiment, a suitable leg support 7 is installed on the fixed support 5 using bolts. The leg support 7 provides support for the patient's legs during tumor care. Rotating the first adjusting bolt 10 upwards causes the second locking plate 24 to move upwards and disengage from the top limiting slot 8, allowing for adjustment of the limiting side plate 6, the fixed support 5, and the leg support 7. After adjustment to the appropriate position, rotating the first adjusting bolt 10 downwards causes the second locking plate 24 to move downwards, re-entering the top limiting slot 8 at the top of the current limiting side plate 6, thus fixing the positions of the limiting side plate 6, the fixed support 5, and the leg support 7. The overall position of the support base 2, the inner adjusting support plate 3, and the top support platform 4 is then adjusted by rotation, with the leg support 7 providing support. Rotating the second adjusting bolt 22 further adjusts the position of the leg support 7. When the bolt 22 rotates, it drives the first clamping plate 21 to move into the bottom fixed box 18. The first clamping plate 21 restricts the rotation position of the inner rotating round seat 19 through the side limiting groove 20 on the outside of the inner rotating round seat 19, thereby fixing the rotation angle of the support base 2, the inner adjusting support plate 3 and the top support platform 4, and adapting to different leg support conditions. By rotating the rotating handwheel 17, the rotating handwheel 17 drives the worm gear 16 to rotate in the support base 2. The worm gear 16 drives the meshing worm wheel 15 to rotate. When the worm wheel 15 rotates, it drives the adjusting screw 14 to rotate. The adjusting screw 14 drives the outer inner adjusting support plate 3 to slide and adjust in the support base 2. The support height of the top support platform 4, the fixed support platform 5, the limiting side plate 6 and the leg support 7 is adjusted through the inner adjusting support plate 3 to adapt to different leg support heights. One or two of this device can be set according to the needs of patient care.

[0028] In one embodiment, such as Figures 1 to 4 As shown, the rotation adjustment part includes a worm gear 15, a worm 16, and a rotating handwheel 17. The worm gear 15 is fixedly installed on the outside of the adjusting screw 14. The worm 16 is rotatably arranged inside the support base 2. The worm 16 is meshed with the worm gear 15. The rotating handwheel 17 is rotatably arranged on one side of the support base 2. One end of the worm 16 is fixedly connected to the rotating handwheel 17.

[0029] It should be noted that in this embodiment, the worm gear 15 and worm 16 are meshed together as the transmission method of the rotation adjustment part. The transmission of the worm gear 15 and worm 16 has self-locking property. When the rotation adjustment is completed and the worm 16 stops rotating, the worm gear 15 cannot drive the worm 16 to rotate in the opposite direction. This can stably maintain the rotation position of the adjusting screw 14, thereby ensuring that the height position of the inner adjusting support plate 3 and the top support platform 4 is fixed, and improving the stability of the bracket after height adjustment.

[0030] In one embodiment, such as Figures 1 to 3 As shown, a side fixing box 9 is bolted to one side of the top support platform 4. A second clamping plate 24 is slidably arranged inside the side fixing box 9. Multiple top limiting grooves 8 that cooperate with the second clamping plate 24 are equidistantly opened on the top of the limiting side plate 6. A first adjusting bolt 10 is threadedly installed inside the side fixing box 9. The bottom end of the first adjusting bolt 10 is rotatably connected to the second clamping plate 24. Limiting rods 11 are symmetrically fixed to the top of the second clamping plate 24. The limiting rods 11 are slidably connected to the side fixing box 9.

[0031] It should be noted that in this embodiment, the No. 1 adjusting bolt 10 is threaded inside the side fixing box 9 and its bottom end is rotatably connected to the No. 2 clamping plate 24. By rotating the No. 1 adjusting bolt 10, the No. 2 clamping plate 24 can be moved up and down, thereby realizing the engagement or disengagement of the No. 2 clamping plate 24 with the top limit clamping groove 8, which facilitates the adjustment and fixation of the position of the fixed support 5, and the operation is convenient and flexible.

[0032] In one embodiment, such as Figures 1 to 4 As shown, the bottom of the top support platform 4 is symmetrically fixed with a limiting slide plate 12, the limiting slide plate 12 is slidably connected to the support base 2, and a limiting plate 13 is fixed to the outside of the limiting slide plate 12, the limiting plate 13 is slidably connected to the support base 2.

[0033] It should be noted that in this embodiment, the limiting slide plate 12 and the supporting base 2 are limited to slide. The limiting plate 13 restricts the adjustment height position of the limiting slide plate 12, the top support platform 4 and the inner adjusting support plate 3, thereby improving the stability of the adjustment.

[0034] In one embodiment, such as Figures 4 to 6As shown, the bottom fixing box 18 has a second adjusting bolt 22 installed on its internal thread, and one end of the second adjusting bolt 22 is rotatably connected to the first clamping plate 21.

[0035] It should be noted that in this embodiment, the position of the first card plate 21 in the bottom fixed box 18 is adjusted by the second adjusting bolt 22, and the rotation position of the inner rotating round seat 19 is restricted by the cooperation between the first card plate 21 and the side limiting slot 20.

[0036] In one embodiment, such as Figures 1 to 5 As shown, multiple casters 23 are installed at the bottom of the support base 1.

[0037] It should be noted that in this embodiment, the overall position of the support base 1 is adjusted by moving the caster wheel 23.
