Description

Pre-sports leg press

技术领域 technical field

本实用新型涉及体育器械，具体涉及一种体育运动前用压腿装置。 The utility model relates to sports equipment, in particular to a leg pressing device before sports.

背景技术 Background technique

在体育运动前，需要做热身拉筋热身活动，以提升运动能力，避免运动伤害。现在的压腿运动一般借助具有一定高度的物体，例如高台、桌椅、双杠等，将腿放置其上进行压腿运动。但是这种简易的压腿辅助设备容易出现站不稳、甚至腿部韧带受伤等问题。压腿运动需要将腿放在与腰同高的物体上，才能获得满意的效果。 Before sports, it is necessary to do warm-up and stretching to improve sports ability and avoid sports injuries. The current leg pressing exercise generally relies on objects with a certain height, such as high platforms, tables and chairs, parallel bars, etc., on which the legs are placed to perform the leg pressing exercise. However, this kind of simple leg press auxiliary equipment is prone to problems such as unstable standing and even leg ligament injury. Leg presses require the legs to be placed on an object at waist height in order to achieve satisfactory results.

发明内容 Invention content

本实用新型要解决的技术问题是提供一种效果好的体育运动前用压腿装置。 The technical problem to be solved by the utility model is to provide a leg press device with good effect before sports.

为了解决上述技术问题，本实用新型的技术方案为： In order to solve the problems of the technologies described above, the technical solution of the utility model is:

一种体育运动前用压腿装置，包括两个并置的“Г”形支架，每个“Г”形支架均包括固定在基础上的支腿和支腿上端的悬臂，悬臂端部具有贯穿的螺纹孔，螺纹孔内穿设立置的丝杠，丝杠上端设置手轮，矩形截面横梁的两端分别通过滚动轴承与两丝杠下端转动连接，矩形截面横梁的上表面间隔设置两个用于承托腿部的凹陷部。 A leg press device used before sports, including two juxtaposed "Г"-shaped brackets, each "Г"-shaped bracket includes a leg fixed on the foundation and a cantilever at the upper end of the leg, and the end of the cantilever has a penetrating The threaded hole of the threaded hole is installed with a lead screw, and the upper end of the lead screw is provided with a handwheel. The hollow part that supports the legs.

上述体育运动前用压腿装置，位于手轮下方且靠近手轮的丝杠上设置链轮，两链轮通过链条连接。 The above-mentioned leg pressing device for physical exercise is located below the handwheel and is provided with a sprocket on the lead screw close to the handwheel, and the two sprockets are connected by a chain.

上述体育运动前用压腿装置，凹陷部的上表面附着一层橡胶垫。 In the above-mentioned leg pressing device before physical exercise, a layer of rubber pad is attached to the upper surface of the concave part.

上述体育运动前用压腿装置，悬臂的长度为1-1.2m。 The above-mentioned leg press device is used before sports, and the length of the cantilever is 1-1.2m.

上述体育运动前用压腿装置，悬臂的截面为圆柱形。 The above-mentioned leg pressing device is used before sports, and the section of the cantilever is cylindrical.

矩形截面横梁通过两根立置的丝杠悬吊在两个并置的“Г”形支架上，压腿时，通过旋转手轮使得丝杠转动，进而矩形截面横梁上下移动，使得矩形截面横梁的高度合适，然后将腿放置于凹陷部上，进行压腿运动即可，在压腿的过程中，手可以握住悬臂以保持身体平衡。矩形截面横梁的高度可以调节，手可以握住悬臂，故活动效果好。 The rectangular cross-section beam is suspended on two juxtaposed "Г"-shaped brackets through two vertical screw screws. When pressing the legs, the screw rotates by rotating the hand wheel, and then the rectangular cross-section beam moves up and down, so that the rectangular cross-section beam The height is appropriate, and then the legs are placed on the concave part, and the leg pressing exercise can be performed. During the leg pressing process, the hand can hold the cantilever to keep the body balanced. The height of the rectangular cross-section beam can be adjusted, and the cantilever can be held by hand, so the activity effect is good.
