Description

Technical Field

[0001] The utility model relates to a leg press, belonging to the technical field of fitness devices. Background Art

[0002] Most leg press devices are a kind of exercise device implemented in large fitness equipment. For example, by clamping the legs to pull a heavy weight block through a steel wire rope, etc. Such exercise equipment is large in size, heavy, inconvenient to carry, and has a relatively high cost price. It is not a popular commodity suitable for families or individuals. In the prior art, a small leg press device has emerged. For example, as described in the patent application number "202210257755.4" and the patent name "A Leg Beautifying Device", the leg beautifying device includes a first pressing plate, a second pressing plate, a connecting member. One end of the first pressing plate is provided with a first stress plate, and the other end is provided with a first connecting plate. One end of the second pressing plate is provided with a second stress plate corresponding to a second connecting plate. The first connecting plate and the second connecting plate are connected by a connecting member. An elastic member is provided between the surface of the first connecting plate away from the second connecting plate or the surface of the second connecting plate away from the first connecting plate and the connecting member. When the legs squeeze the first stress plate and the second stress plate, the distance between the first connecting plate and the second connecting plate increases, and the elastic member is squeezed. The elastic member will have an elastic force on the connecting plate to reset the first stress plate and the second stress plate. In the above structure, although a convenient and simple leg press function is provided, there are still many disadvantages found in use. For example, during the process of clamping the legs, the distance and angle between the left and right thighs are changed. Therefore, there will be a gap between the thighs and the stress plate when using the leg beautifying device, and the thighs and the stress plate cannot fit together, resulting in local small-area extrusion causing tenderness and poor comfort.
