Description

Technical Field

[0001] The utility model relates to lower limb training, in particular to a footrest device in lower limb training, belonging to the field of mechanical technology. Background Art

[0002] In lower limb training equipment, the footrest is used to restrain the feet and is a commonly used configuration on rehabilitation training equipment. It is a common configuration in applications related to training equipment in Chinese patents. For example, the technical solutions disclosed in CN209884684U (Lower Limb Joint Rehabilitation Trainer), CN106618968A Ankle Joint Training Device, and CN116327551A An Ankle Joint Rehabilitation Training Device all use footrests. The footrests used in current such equipment are a footrest plate connected with foot restraint straps. Such a footrest is okay for simple foot fixation and restraint, but it cannot adapt to the force on the feet during foot training and cannot simulate the movements of the feet. Moreover, the existing above-mentioned footrests have poor adaptability to patients with foot valgus or varus. These patients often feel uncomfortable after being restrained by the existing footrests. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above problems existing in the current footrest device and provide a footrest device.

[0004] To achieve the purpose of the utility model, the following technical solution is adopted: A footrest device includes a footrest plate, on which a restraint strap is fixedly connected. The front part of the footrest plate is rotatably connected to an upper support through a horizontal first shaft, the upper support is rotatably connected to a lower support through a horizontal second shaft, a indexing pin is installed on the upper support, and a limit pin hole corresponding to the indexing pin is opened on the lower support. After the limit pin is inserted into the limit pin hole, the upper support cannot rotate around the second shaft.

[0005] Further; a vertically arranged connecting rod is fixedly connected to the lower support, the other end of the connecting rod is fixedly connected with a ball head, spherical cavities are processed on the opposite surfaces of two split clamping blocks, the ball head is located in the spherical cavities, and the two split clamping blocks are fixedly connected together through a handle bolt.

[0006] Further; the front end of the upper support is U-shaped, there are two ears below the front part of the footrest plate, the first shaft is a bolt shaft, and the ears are rotatably connected to the U-shaped edges through the bolt shaft, and a nut is screwed on the bolt shaft to lock the nut so that the footrest plate cannot rotate around the first shaft.

[0007] The positive and beneficial technical effects of the utility model are as follows: In addition to being able to achieve the functions of the existing footrest, this footrest device can also simulate various foot movements, which will be specifically described in combination with the specific embodiments.

[0012] To more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only elaborations of the present utility model and do not limit the scope of the present utility model.

[0013] With reference to the accompanying drawings, the present utility model is further explained in detail. The marks in the drawings are as follows: 1: footrest; 2: restraint strap; 3: upper support; 4: first shaft; 5: ear; 6: lower support; 7: indexing pin; 8: second shaft; 9: limit pin hole; 10: connecting rod; 11: ball head; 12: handle bolt; 13: two-piece clamping block.

[0014] The horizontal direction and vertical direction in this application are the corresponding directions in the figure, which are for better explaining and illustrating the content of the technical solution and do not represent the actual direction in use.

[0015] As shown in the accompanying drawings, a footrest device includes a footrest. A restraint strap 2 is fixedly connected to the footrest. The front part of the footrest is rotatably connected to the upper support through a horizontally arranged first shaft 4. In this embodiment, the front end of the upper support is U-shaped. There are two ears 5 below the front part of the footrest. The ears are rotatably connected to the U-shaped edge through a bolt shaft. The first shaft is a bolt shaft, and a nut is screwed on the bolt shaft. Locking the nut makes the footrest unable to rotate around the first shaft. After the locking nut and the indexing pin are inserted into the limit pin hole, the footrest, the upper support, and the lower support become an integral body, which is the same as the traditional footrest structure. When the first shaft is rotatable, the footrest can rotate around the first shaft, and the movement of standing on tiptoe can be simulated.

[0016] The upper support 3 is rotatably connected to the lower support 6 through a horizontally arranged second shaft 8. An indexing pin 7 is installed on the upper support, and a limit pin hole 9 corresponding to the indexing pin is opened on the lower support. After the limit pin is inserted into the limit pin hole, the upper support cannot rotate around the second shaft. After the indexing pin is pulled out, the upper support can rotate around the second shaft, and the movement of taking a step can be simulated.

[0017] A vertical connecting rod 10 is fixedly connected to the lower support 6 described above. The other end of the connecting rod 10 is fixedly connected to a ball head 11. Spherical cavities are machined on two opposite surfaces of the two-piece clamping block 13, and the ball head is located in the spherical cavity. The two-piece clamping block is fixedly connected together by a handle bolt. By loosening the handle bolt, the direction of the connecting rod can be adjusted to accommodate patients with foot deformities.

[0018] After the embodiments of the present invention are described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention all belong to the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments described in the specification.
