[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] The inventors discovered through analysis of existing technologies that when using medical devices such as gastrointestinal machines and delivery beds, it is necessary to adjust the angle at which the patient's legs are spread apart. Patients of different body types have different knee and lower leg positions when their legs are spread apart. Existing leg support structures are generally one-piece molded or can only adjust the height and position, which is difficult to adapt to all patients and will cause discomfort during use. Therefore, it is necessary to design a more comfortable leg support structure.
[0024] Reference Figure 1 This application illustrates a leg support structure, which includes: a lifting rod 10, a rotating assembly, a telescopic cross arm 30, a support plate 50, and an angle adjustment assembly 40 for adjusting the angle of the support plate 50.
[0025] The lifting rod 10 is vertically arranged, and the rotating component is connected to the lifting rod 10 and is driven to rise and fall by the lifting rod 10.
[0026] The telescopic cross arm 30 is connected to the rotating assembly and is driven to rotate by the rotating assembly; wherein the rotation axis of the rotating assembly is parallel to the lifting rod 10.
[0027] The angle adjustment component 40 is connected to the telescopic cross arm 30 and is driven to extend and retract by the telescopic cross arm 30; wherein, the rotation axis of the angle adjustment component 40 is perpendicular to the lifting rod 10 and the telescopic cross arm 30 respectively.
[0028] In the embodiments of this application, addressing the issue of insufficient comfort in existing leg support structures, this application provides a leg support structure that can be adjusted at multiple angles. Specifically, the leg support structure includes: a lifting rod 10, a rotating assembly, a telescopic cross arm 30, a support plate 50, and an angle adjustment assembly 40 for adjusting the angle of the support plate 50. The lifting rod 10 is vertically arranged, and the rotating assembly is connected to and driven by the lifting rod 10 to rise and fall. The telescopic cross arm 30 is connected to and driven by the rotating assembly to rotate. The rotation axis of the rotating assembly is parallel to the lifting rod 10. The angle adjustment assembly 40 is connected to and driven by the telescopic cross arm 30 to extend and retract. The rotation axis of the angle adjustment assembly 40 is perpendicular to both the lifting rod 10 and the telescopic cross arm 30. Through the cooperation of the lifting rod 10, the rotating assembly, the telescopic cross arm 30, and the angle adjustment assembly 40, the leg support structure can freely adjust its position, height, and angle according to different patients and usage conditions, achieving a more comfortable leg support.
[0029] The following will further describe a leg support structure in this exemplary embodiment.
[0030] In an embodiment of this application, the leg support structure includes: a lifting rod 10, a rotating assembly, a telescopic cross arm 30, a support plate 50, and an angle adjusting assembly 40 for adjusting the angle of the support plate 50;
[0031] The lifting rod 10 is vertically arranged, and the rotating component is connected to the lifting rod 10 and is driven to rise and fall by the lifting rod 10.
[0032] The telescopic cross arm 30 is connected to the rotating assembly and is driven to rotate by the rotating assembly; wherein the rotation axis of the rotating assembly is parallel to the lifting rod 10.
[0033] The angle adjustment component 40 is connected to the telescopic cross arm 30 and is driven to extend and retract by the telescopic cross arm 30; wherein, the rotation axis of the angle adjustment component 40 is perpendicular to the lifting rod 10 and the telescopic cross arm 30 respectively.
[0034] It should be noted that the height of the leg rest is adjusted by the lifting rod 10, the horizontal position of the leg rest is adjusted by the telescopic cross arm 30, the distance between the two leg rests is adjusted by the rotating component, and the angle of the support plate 50 is adjusted by the angle adjustment component 40; wherein, the angle adjustment component 40 is a spherical rotating structure; so that the adjusted leg rest adapts to the position of the patient's legs, making the use of the leg rest more comfortable.
[0035] In embodiments of this application, a clamping base is also included, which is fixedly connected to the lower end of the lifting rod 10.
[0036] It should be noted that the leg support structure can be adapted to various medical devices by means of the detachable connection between the clamping base and the medical device, and the overall position of the leg support structure can also be changed by means of the clamping base.

The horizontal slider is sleeved on the telescopic horizontal arm 30 and slides along the telescopic horizontal arm 30; wherein the telescopic horizontal arm 30 is perpendicular to the lifting rod 10.
[0038] It should be noted that the vertical slider can rotate around the lifting rod 10 or slide along the lifting rod 10 and the telescopic cross arm 30. That is, this application achieves lifting and lateral movement by sliding the rotating component on the lifting rod 10 and the telescopic cross arm 30.

[0041] When the upper clamping block and the lower clamping block are in contact with each other, a clamping hole is formed between the grooves of the upper clamping block and the lower clamping block for the telescopic cross arm 30 to pass through.

When the upper clamping block and the lower clamping block are loosened, the horizontal slider can slide along the telescopic horizontal arm 30. When the upper clamping block and the lower clamping block are tightened, the horizontal slider is fixed on the telescopic horizontal arm 30.
[0043] In an embodiment of this application, the vertical slider is provided with a second fastener for fixing the vertical slider to the lifting rod 10; the vertical slider is provided with a through hole for the lifting rod 10 to pass through.
