Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a medical footstool. Background Technology

[0002] In order to flexibly increase the standing height of medical staff, footstools are usually provided in the operating room.

[0003] In existing technologies, most footstools are height-adjustable to accommodate medical staff of different heights. For example, Chinese Patent [Publication No.: CN219439472U] discloses a lightweight adjustable medical surgical footstool, including a support platform and a support frame. The main body of the support platform is a rectangular plate, and sleeves are fixedly connected to the four corners of the rectangular plate. The sleeves are slidably mounted on the longitudinal rods of the support frame. One support frame is set on each of the left and right sides of the support platform, and the main body of the support frame is a rectangular frame. Several spring pins are installed on the longitudinal rods, and the sleeves are provided with through holes that cooperate with the spring pins.

[0004] However, when adjusting the height of this device, multiple spring pins need to be pressed back into the sleeve, which is inconvenient and troublesome to operate. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a medical footstool that solves the problem in the prior art where adjusting the height of the footstool requires pressing multiple spring pins back into the sleeve, which is inconvenient and troublesome.

[0006] This utility model solves the above-mentioned technical problems through the following technical means: A medical footstool includes a footboard. Support frames are provided at both ends of the bottom of the footboard. Each support frame includes a first support plate and a second support plate. One end of the first support plate is provided with a hinge shaft, which is hinged to the bottom of the footboard. The other end of the first support plate is hinged to the second support plate. A sliding shaft is rotatably mounted on the free end of the second support plate. The sliding shaft is slidably mounted on the footboard along its length. An elastic element is provided between the first and second support plates to maintain a tendency for the first and second support plates to rotate closer together. A limiting element is provided on the footboard to restrict the movement of the sliding shaft along its length.

[0007] By setting up the above structure, when adjusting the height, the operating limit member is operated to disengage from the limit of the sliding shaft, and the elastic member causes the first support plate and the second support plate to rotate closer to each other, thereby raising the height of the pedal. Pressing down the pedal forcefully can lower the height of the pedal. The operation is simple, convenient and quick.

[0008] Furthermore, the limiting member is slidably installed on the pedal along the height direction of the pedal. A groove is provided on the limiting member corresponding to the position of the sliding shaft along the length direction of the pedal. The end of the sliding shaft is located in the groove. Multiple limiting grooves are provided on the upper wall of the groove along the length direction of the groove. When the sliding shaft is locked in the limiting groove, the limiting member restricts the sliding shaft from sliding along the length direction of the pedal.

[0009] By setting up the above structure, pulling the limiting member upwards causes the sliding shaft to disengage from the limiting groove and enter the sliding channel, thus releasing the limiting member's restriction on the sliding shaft. Pressing the limiting member downwards causes the sliding shaft to enter the limiting groove, restricting its movement along the length of the pedal and further improving operational convenience.

[0010] Furthermore, the limiting member has a waist-shaped groove at the position of the hinge shaft along the height direction of the pedal, and the free end of the hinge shaft is slidably disposed in the waist-shaped groove.

[0011] By setting the above structure, the sliding connection between the limiting component and the pedal is realized with the help of the hinge shaft, which effectively simplifies the structure of the limiting component.

[0012] Furthermore, the limiting member has a buckle groove on both sides.

[0013] By setting up the above structure, hand grip space is provided, making it easy to pull the limiting component upward.

[0014] Furthermore, a support block is provided between the first support plate and the second support plate, and the two ends of the support plate are respectively rotatably connected to the ends of the first support plate and the ends of the second support plate.

[0015] By setting up the above structure, the support surface at the bottom of the support frame is increased, effectively improving stability.

[0016] Furthermore, a base is provided below the pedal, and the support block is slidably disposed on the base along the length direction of the base.

[0017] By setting up the above structure, the two support frames are connected through the base, increasing the stability of the footstool during use.

[0018] Furthermore, the elastic element includes a tension spring, and both ends of the tension spring are fixedly connected to mounting blocks, with the two mounting blocks respectively rotatably mounted on the hinge shaft and the sliding shaft.

[0019] The beneficial effects of this utility model are: 1. This utility model, by setting a first support plate, a second support plate, a sliding shaft, and an elastic element, allows for height adjustment. When adjusting the height, the operating limit element disengages from the limit of the sliding shaft, and the elastic element causes the first support plate and the second support plate to rotate closer to each other, thereby raising the height of the pedal. Conversely, pressing down on the pedal forcefully lowers the height of the pedal. The operation is simple, convenient, and quick.

[0020] 2. This utility model, by setting a sliding groove and a limiting groove, allows the sliding shaft to disengage from the limiting groove and enter the sliding groove when the limiting member is pulled upward, thus releasing the limiting member's restriction on the sliding shaft. Pressing the limiting member downward allows the sliding shaft to enter the limiting groove, restricting the movement of the sliding shaft along the length of the pedal, further improving the convenience of operation.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] like Figs. 1-3 As shown, a medical footstool of this utility model includes a footboard 1. Support frames 2 are provided at both ends of the bottom of the footboard 1. Each support frame 2 includes a first support plate 21 and a second support plate 22. A hinge shaft 211 is provided at one end of the first support plate 21, which is hinged to the bottom of the footboard 1 via the hinge shaft 211. The other end is hinged to the second support plate 22. A sliding shaft 221 is rotatably mounted on the free end of the second support plate 22. The sliding shaft 221 is slidably mounted on the footboard 1 along its length. In this embodiment, through grooves 11 are provided on both sides of the footboard 1 along its length, and both ends of the sliding shaft 221 are slidably inserted into the through grooves 11. An elastic element 3 is provided between the first support plate 21 and the second support plate 22. The elastic element 3 is used to keep the first support plate 21 and the second support plate 22 tending to rotate closer to each other. A limiting element 4 is provided on the footboard 1 to restrict the movement of the sliding shaft 221 along its length. When adjusting the height, operate the limiting member 4 to disengage from the limiting of the sliding shaft 221. The elastic member 3 causes the first support plate 21 and the second support plate 22 to rotate closer to each other, thereby raising the height of the pedal 1. Pressing down the pedal 1 forcefully will lower the height of the pedal 1. The operation is simple, convenient and quick.

[0025] In this embodiment, the limiting member 4 is slidably mounted on the pedal 1 along the height direction of the pedal 1. A groove 41 is formed on the limiting member 4 along the length direction of the pedal 1 at the position corresponding to the sliding shaft 221. The end of the sliding shaft 221 is located within the groove 41. Multiple limiting grooves 42 are provided on the upper wall of the groove 41 along its length direction. When the sliding shaft 221 is engaged within the limiting groove 42, the limiting member 4 restricts the sliding shaft 221 from sliding along the length direction of the pedal 1. In other embodiments, one end of the limiting member 4 can be hinged to the pedal 1, and the engagement or disengagement of the sliding shaft 221 from the limiting groove 42 can be achieved by rotation. In this embodiment, by slidably mounting the limiting member 4 on the pedal 1 along the height direction of the pedal 1, when adjusting the height, the limiting member 4 is pulled upwards, causing the sliding shaft 221 to disengage from the limiting groove 42 and enter the groove 41, thus releasing the limiting member 4 from restricting the sliding shaft 221. Pressing the limiting member 4 downwards allows the sliding shaft 221 to enter the limiting groove 42, restricting the sliding shaft 221 from moving along the length of the pedal 1, thus further improving the convenience of operation.

[0026] In this embodiment, the limiting member 4 has a waist-shaped groove 43 at the position corresponding to the hinge shaft 211 along the height direction of the pedal 1, and the free end of the hinge shaft 211 is slidably disposed in the waist-shaped groove 43. In some other embodiments, a locking block and a locking groove can also be used to achieve a sliding connection. In this embodiment, the sliding connection between the limiting member 4 and the pedal 1 is achieved by means of the hinge shaft 211, which effectively simplifies the structure of the limiting member 4.

[0027] In this embodiment, the limiting member 4 has a buckle groove 44 on both sides to provide hand grip space and facilitate pulling the limiting member 4 upward.

[0028] In this embodiment, a support block 23 is provided between the first support plate 21 and the second support plate 22, and the two ends of the support plate are rotatably connected to the ends of the first support plate 21 and the second support plate 22, respectively. This raises the support surface at the bottom of the support frame 2, effectively improving stability.

[0029] In this embodiment, a base 5 is provided below the footrest 1, and a support block 23 is slidably disposed on the base 5 along its length. This connects the two support frames 2 via the base 5, increasing the stability of the footrest during use. In this embodiment, each end of the support block 23 is provided with a connecting shaft 231, and the support block 23 is rotatably connected to the first support plate 21 and the second support plate 22 via the two connecting shafts 231 respectively. A slot 51 is provided on the base 5 at the position corresponding to the support block 23 along its length, and the connecting shaft 231 is slidably disposed within the slot 51.

[0030] In this embodiment, elastic elements 3 are provided on both sides of the support frame 2. The elastic elements 3 include tension springs 31, and mounting blocks 32 are fixedly connected to both ends of the tension springs 31. The two mounting blocks 32 are respectively rotatably mounted on the hinge shaft 211 and the sliding shaft 221. In some other embodiments, torsion springs can be provided at the hinge ends of the first support plate 21 and the second support plate 22 instead of tension springs 31. The torsion springs can keep the first support plate 21 and the second support plate 22 tending to rotate closer to each other.

[0031] The working principle of this medical footstool is as follows: When adjusting the height: First, apply pressure to pedal 1, then lift the limiting member 4 upwards, causing the limiting member 4 to move upwards relative to pedal 1. Specifically, press pedal 1 with both thumbs and hook the other fingers into the latch groove 44 to lift the limiting member 4 upwards (or you can press pedal 1 with one foot and lift the limiting member 4 upwards with both hands). During this process, the sliding shaft 221 disengages from the limiting groove 42 and enters the sliding groove 41, releasing the limiting member 4 from restricting the sliding shaft 221.

[0032] If it is necessary to raise the height of pedal 1, while keeping the relative height of the limiting member 4 and pedal 1 unchanged, reduce the pressure applied to pedal 1 by both thumbs, and the tension spring 31 causes the first support plate 21 and the second support plate 22 to rotate closer to each other, thereby raising the height of pedal 1.

[0033] If it is necessary to lower the height of pedal 1, while keeping the relative height of the limiting member 4 and pedal 1 unchanged, increase the pressure applied to pedal 1 by both thumbs, so that the first support plate 21 and the second support plate 22 rotate away from each other, and further stretch the tension spring 31, thereby lowering the height of pedal 1.

[0034] After the height adjustment is completed, the pressure applied by both thumbs to the pedal 1 remains unchanged, the other fingers release the latch 44, and push the limiting member 4 downward so that the sliding shaft 221 enters the limiting groove 42, restricting the sliding shaft 221 from moving along the length of the pedal 1, locking the height of the pedal 1, and finally the hands are removed from the pedal 1.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
