Example 1

The utility model provides an adjustable foot rest, includes bottom plate 2 and locates support 1 on the bottom plate, support 1 includes two support legs 12 and a whippletree 11, support leg 12 has a top and a bottom, whippletree 11 connects two the top of support leg 12 makes prop up framework 1 and become n type, the quantity of support 1 is greater than 2, is located on the bottom plate 2 support 1 along the axis of bottom plate 2 is arranged.

The plurality of supports 1 are matched to play a role of supporting the lower limbs, for example, in one embodiment, the heights of the supports 1 are not consistent, and preferably, the supports 1 are arranged from high to low along the axis of the base plate 2, so that the structure shown in fig. 1 is formed. When the leg supporting device is used, the leg supporting device can be used for supporting the lower leg to enable the lower leg to keep a certain inclination degree, so that a doctor can conveniently check or perform an operation, and due to the fact that a large gap exists between the lower part of the lower. In another embodiment, without changing the height arrangement of the front support, as shown in fig. 9, the sole plate can step on the bar 11 of one support 1, and the leg can be supported by the other supports 1, so as to bend between the thigh and the lower leg. Preferably, the bottom plate 2 is provided with 1 or more than 1 heel placing groove 22, the shape of which is matched with the heel, and the heel placing groove is used for accommodating and positioning the heel, and can also play a certain limiting role to limit the movement of the heel. Preferably, the heel placement groove 22 is not placed under the bar 11.

The adjustable foot rests with the brackets 1 arranged in sequence from high to low can support various bending modes of the lower limbs under the condition of not changing the basic structure of the adjustable foot rests, and the trouble of manual fixation is reduced.

In the preferred embodiment, the bar 11 is wrapped with a soft layer. Preferably, the outer side of the cross bar 11 is wrapped with a soft sponge layer or a silica gel layer. The soft material can reduce the oppression sense of the lower limb support position and improve the comfort level.

The design shown in fig. 3, the upper part of the horizontal bar is a concave surface. In use, for example, in fig. 8, the concavity may conform to the shape of the lower limb, improving comfort, and additionally providing a positioning function to center the lower limb.

As shown in FIG. 4, two side plates 110 are respectively disposed on two sides of the bar 11, and the top of the side plates 110 extends upward beyond the side surfaces of the bar. The side plate 110 is used to limit the range of movement of the lower limbs and prevent the lower limbs from falling off the stand 1.

Example 2

Unlike embodiment 1, the holder 1 is detachably fixed to the base plate 2. By means of the detachable manner, a plurality of supports 1 of different heights can be arranged to achieve different inclinations, and some supports 1 can also be used for fixing the lower leg as shown in fig. 10 and 11.

In one embodiment, the disassembling is realized by the following structure: as shown in fig. 5, the adjustable footrest further includes a transverse plate 13, the transverse plate 13 is fixed on the two support legs 12, the two support legs 12 penetrate through the transverse plate 13, and the cross section of the support leg 12 at the penetrating position is located in the transverse plate 13; the bottom plate 2 is provided with two sliding grooves 21 in parallel, the opening of the sliding groove 21 is positioned at the top of the bottom plate 2, the width of the sliding groove 21 is larger than that of the bracket legs 12, the bottoms of the two bracket legs 12 are positioned in the sliding groove 21, the bottom of the transverse plate 13 is in contact with the top of the bottom plate 2, and the transverse plate is fixed on the bottom plate 2 through a fixing piece 14.

As shown in fig. 6, before the stand 1 is fixed, the bottom of the stand leg 12 is moved to a proper position in the slide groove 21, and then the stand is fixed to the base plate by the fixing member 14.
