Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical nursing equipment, in particular to a leg exercise equipment. Background Art
[0002] During or after the treatment of leg problems, neurosurgery patients generally cooperate with appropriate auxiliary exercises to ensure the overall rehabilitation effect. For example: leg clamping, leg lifting, knee flexion and extension, ankle flexion and extension, etc. According to the current market and various public documents, exercise equipment related to leg lifting, knee flexion and extension, and ankle flexion and extension are relatively common. However, when performing leg clamping exercises, there is currently a lack of relevant equipment. Only some sports training equipment has relevant functions. However, in clinical nursing, considering the requirements of convenience and cost, this type of sports equipment is not suitable for widespread promotion in clinical practice. Summary of the invention
[0003] The utility model aims to provide a small-sized leg exercise device with low requirements on the use environment.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a leg exercise device, comprising two symmetrically arranged leg clamps, the leg clamps are L-shaped, and the vertical sides of the L-shape face inward; the rear sides of the leg clamps are provided with inclined connecting arms, and the connecting arms of the two leg clamps are hinged to the hinge seat located between the leg clamps to form a V-shaped structure;
[0005] It also includes an elastic antagonism mechanism, which includes a center rod extending along the front-to-back direction and arranged between the two leg clamping plates, and the rear end of the center rod is fixedly connected to the hinge seat; a sliding disk is provided in the middle of the center rod, and a resisting disk is provided on the center rod in front of the sliding disk; an antagonism spring is provided on the outer sleeve of the center rod between the sliding disk and the resisting disk; the elastic antagonism mechanism also includes two connecting rods, one end of the connecting rod is hinged to the rear side of the leg clamping plate, and the other end is hinged to the sliding disk.
[0006] Preferably, the retaining disc is sleeved on the center rod and forms a threaded fit with the center rod.
[0007] Preferably, a soft pad is provided on the surface of the leg clamping plate, and the soft pad is composed of a sponge core and a mesh cloth sleeved on the surface of the sponge core.
[0008] Preferably, an anti-pinch protection cover is provided outside the hinge seat.
[0009] Preferably, a pad is provided at the bottom of the horizontal edge of the leg clamping plate, a plurality of ball grooves are evenly provided at the bottom of the pad, and rolling balls are embedded in the ball grooves.
[0010] The beneficial effects of the utility model are mainly reflected in that it can assist patients in performing leg clamping exercises, and at the same time, it is compact and easy to arrange and use in the ward. Specifically, the utility model is mainly used for patients who need to perform leg clamping exercises. When using it, first place the utility model flat on a hard chair, bench or other flat surface. After the patient sits down, place both legs on the two leg clamping boards respectively, and clamp the legs inward to perform leg clamping exercises. During the leg clamping exercise, the counter spring can effectively increase the intensity of the exercise and ensure the effect of the exercise. The utility model has a simple and compact structure and a compact size, and is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the top view structure of the utility model;
[0012] Figure 2 for Figure 1 Center AA view. DETAILED DESCRIPTION
[0013] like Figure 1-2 The leg exercise device shown is mainly used in clinical practice to assist patients who need to perform leg clamping exercises to achieve the effect of leg exercise. It includes two leg clamping boards 1 that are symmetrically arranged on the left and right. The leg clamping boards 1 are L-shaped, and the vertical sides of the L-shaped sides face inward. The leg clamping boards 1 and related components (such as the rigid components such as the connecting arm 2, the hinge seat, the center rod 4, the connecting rod 8, etc. described below) are uniformly made of hard plastic parts, which have the characteristics of light weight and high structural strength, and can be low-cost, so as to facilitate popularization and promotion.
[0014] like Figure 1 As shown, the rear side of the leg clamp board 1 of the utility model is provided with an inclined connecting arm 2, and the connecting arms 2 of the two leg clamp boards 1 are hinged to the hinge seat 3 located between the leg clamp boards 1 to form a V-shaped structure. In the description of the utility model, the front, back, left, and right are based on the front, back, left, and right of the patient in actual use. Figure 1 As shown in , the top is the front and the bottom is the back. Since the hinge seat 3 is hinged with each component, in order to prevent pinching, a better approach may be that the hinge seat 3 is provided with an anti-pinch protective cover.
[0015] The utility model also includes an elastic counter mechanism, which includes a center rod 4 extending in the front-to-back direction and arranged between the two leg clamping plates 1. The rear end of the center rod 4 is fixedly connected to the hinge seat 3, and the connection form can be that the two are integrally formed. Alternatively, the two can be connected by bolts after being processed separately. The middle part of the center rod 4 is sleeved with a sliding plate 5, which is a circular sleeve body, and a connecting ear for the hinged connecting rod 8 is usually arranged on the left and right sides.
[0016] A resisting plate 6 is arranged on the center rod 4 on the front side of the sliding plate 5, and an antagonistic spring 7 is arranged on the outer sleeve of the center rod 4 between the sliding plate 5 and the resisting plate 6. The antagonistic spring 7 is a spiral spring. The main function of the resisting plate 6 is to lean against one end of the antagonistic spring 7. It can be fixed or adjustable. The former is simpler, but the antagonistic strength cannot be adjusted. The latter can adjust the antagonistic strength of the antagonistic spring 7 by adjusting the position of the resisting plate 6. The adjustment method usually adopts thread adjustment, such as Figure 1 As shown in , that is to say, the blocking plate 6 is sleeved on the central rod 4 and forms a threaded fit with the central rod 4.
[0017] The elastic antagonism mechanism further comprises two connecting rods 8, one end of the connecting rod 8 is hinged to the rear side of the leg clamping plate 1, and the other end is hinged to the sliding plate 5. When the leg clamping plate 1 moves inward, the sliding plate 5 can be pushed by the connecting rod 8 to move, thereby compressing the antagonism spring 7 to achieve the leg clamping antagonism exercise.
[0018] Considering that the leg clamp 1 is used as a support component for the legs during use, in order to improve comfort, a cushion 9 is provided on the surface of the leg clamp 1, and the cushion 9 is composed of a sponge core and a mesh cloth sleeved on the surface of the sponge core. In addition, since the leg clamp 1 is in direct contact with the plane of the bench and chair during general use, some patients have heavy legs, resulting in large friction, which is not conducive to the sliding of the leg clamp 1 on the table. For this reason, the utility model can also provide a pad 10 at the bottom of the horizontal edge of the leg clamp 1, and a plurality of ball grooves are evenly provided at the bottom of the pad 10, and rolling balls 11 are embedded in the ball grooves to improve the sliding property.
