DETAILED DESCRIPTION

[0023] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0024] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0025] refer to Figure 1A , 1B , 1C and 1D, the scheme shown in the figure is the specific structure of Example 1 of the present application. The foot therapy fixing device of Example 1 of the present application includes a base plate 100, a foot support plate 200 arranged above the base plate 100, and a calf support plate 300 with two ends respectively hinged to the first two, and the hinged positions are the ends on the same side of the base plate 100 and the foot support plate 200; the calf support plate 300 can maintain a certain angle with the base plate 100 after rotation, and the foot support plate 200 can maintain a certain angle with the calf support plate 300 after rotation.

[0026] The calf support plate 300 and the base plate 100 are hinged in such a way that a first groove 110 is provided at one of the ends where the calf support plate 300 and the base plate 100 are hinged to each other, the other end is rotatably disposed in the first groove 110, and a first pivot 120 is provided that passes through both hinged ends.

[0027] The method for keeping the angle unchanged after the calf support plate 300 is realized is as follows: an angle adjustment assembly 400 is provided between the bottom plate 100 and the calf support plate 300, which includes two vertical plates 410 respectively fixed on both sides of the hinged end of the bottom plate 100, a support rod 420 supported at the bottom of the calf support plate 300, and a first fixing nut 430 threadedly connected to both ends of the support rod 420, the vertical plate 410 is provided with an arc opening 411, and both ends of the support rod 420 are respectively slidable through the two arc openings 411, and the first fixing nut 430 is located on the outside of the vertical plate 410. A scale for measuring the angle between the calf support plate 300 and the bottom plate 100 is provided on the outside of the vertical plate 410. When the calf support plate 300 rotates, the support rod 420 moves to different positions in the arc-shaped opening 411. When it is adjusted to the desired angle, the first fixing nut 430 is tightened. Since a scale is provided on the outside of the vertical plate 410, the rotation angle can be understood through the scale, and the calf support plate 300 can be rotated to the same position during the next treatment.

[0028] The manner in which the foot support 200 and the calf support 300 are hinged and the angle is adjustable is as follows: a second groove 210 is provided at one of the ends where the foot support 200 and the calf support 300 are hinged to each other, the other end is rotatably provided in the second groove 210, and a second pivot 220 is provided that passes through both hinged ends at the same time; the second pivot 220 is fixedly connected to the calf support 300, and at least one end is exposed to the side edge of the foot support 200, and this end is threadedly connected with a second locking nut 230; an indicator groove 221 parallel to the calf support 300 is provided at the exposed end of the second pivot 220, and a scale is provided on the side edge of the foot support 200 near the end of the second pivot 220, and this scale is used to measure the angle between the foot support 200 and the calf support 300. After the foot support plate 200 is rotated, it can be kept at a desired angle by tightening the second fixing nut 230 ; the side edge of the foot support plate 200 is also provided with a scale, which mainly cooperates with the indicator groove 221 to understand the specific angle change.

[0029] Since the body shapes of patients are different, the lengths of the calves are also different, so it is necessary to set the calf support plate 300 in an adjustable length. Specifically, the calf support plate 300 includes a first plate 310 and a second plate 320, one end of the first plate 310 is hinged to the bottom plate 100, and the second plate 320 is telescopically connected to the other end of the first plate 310. A slot 311 is provided on the end surface of the non-hinged end of the first plate 310, and a fastening screw 330 is threadedly connected to the side edge, and the end of the fastening screw 330 can penetrate into the slot 311; one end of the second plate 320 is provided with a plug plate 321 with a thinned thickness, and the plug plate 321 can be pushed and pulled and plugged into the slot 311. When it is necessary to adjust the length of the calf support plate 300, loosen the fastening screw 330, then push and pull the second plate 320 to a suitable position, and then re-tighten the fastening screw 330. Furthermore, two side edges of the top of the first flat plate 310 and the second flat plate 320 are provided with raised side plates 340 to prevent the patient's legs from slipping.

[0030] As for the material of the bottom plate 100, the calf support plate 300 and the foot support plate 200, any material can be used as long as it does not hinder the examination and treatment of the patient's foot and does not affect the patient's health. For example, a layer of soft rubber can be laid on the top of the calf support plate 300 and the foot support plate 200 to improve comfort; the main part of the calf support plate 300 and the foot support plate 200 is made of organic glass to reduce the impact on the examination radiation.

[0031] refer to Figure 2A , 2B2C, the scheme shown in the figure is the specific structure of Example 2 of the present application. The difference between this embodiment and Example 1 is that the second fixing nut 230 is eliminated and an angle control assembly 500 is added. The angle control assembly 500 is used to keep the foot support plate 200 always parallel to the base plate 100, that is, to keep the foot support plate 200 in a horizontal or nearly horizontal position under normal circumstances. This embodiment is mainly used for general situations where the patient's feet are kept flat, and there is no need to specially adjust the foot support plate 200 during use, which reduces the number of operating steps.

[0032] Specifically, the angle control component 500 includes a telescopic rod 510 that can be extended and retracted synchronously with the second flat plate 320. The two ends of the telescopic rod 510 are respectively hinged to the foot support plate 200 and the base plate 100. A parallelogram mechanism is formed between the base plate 100, the calf support plate 300, the foot support plate 200 and the telescopic rod 510.

[0033] The angle control assembly 500 further includes a sliding bar 520 and a sleeve 530; the telescopic rod 510 includes a screw 511 and an inner screw barrel 512, one end of the screw 511 is hinged to the bottom plate 100, and the other end is threadedly connected to one end of the inner screw barrel 512, one end of the inner screw barrel 512 is rotatably connected to one end of a connecting rod 514, and the other end of the connecting rod 514 is hinged to the foot support plate 200; the sleeve 530 is sleeved on the inner screw barrel 512, and the side walls of the inner screw barrel 512 at both ends are provided with limiting convex rings 513; the side of the second flat plate 320 is provided with a slot 322, one end of the sliding bar 520 can be slidably inserted into the slot 322, and the other end is fixedly connected to the sleeve 530. Among them, the two ends of the slot 322 are connected, and the slot is provided with a limiting bar 323 for preventing the sliding bar 520 from falling off.

[0034] The connecting rod 514 realizes the rotational connection in the following manner: the end of the connecting rod 514 connected to the inner screw barrel 512 is inserted into the inner screw barrel 512, and a disc 515 is fixedly connected to the end; a limiting ring 516 and a blocking plate 517 are fixed to the inner screw barrel 512 on both sides of the disc 515; the blocking plate 517 is located on the inner side of the disc 515, and is used to prevent the disc 515 from moving inward; the limiting ring 516 is located on the outer side of the disc 515, passes through the connecting rod 514, and has an inner diameter smaller than the diameter of the disc 515.

[0035] When in use, first loosen the fastening screw 330, then rotate the inner screw barrel 512. During the rotation process, the inner screw barrel 512 can not only adjust the length of the entire telescopic rod 510, but also can synchronously adjust the position of the second plate 320 due to the push of the connecting rod 514. After adjustment, tighten the fastening screw 330. Since the bottom plate 100, the calf support plate 300, the foot support plate 200 and the telescopic rod 510 form a parallelogram mechanism, it can ensure that the foot support plate 200 maintains a horizontal position.

[0036] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
