Abstract
Description
Technical Field
[0001] This utility model relates to the field of kneading and pushing disc technology, and in particular to a kneading and pushing disc structure for fitness equipment. Background Technology
[0002] Exercise plays an irreplaceable and crucial role in maintaining health. Currently, an increasing number of fitness equipment items are being installed in urban public places such as residential communities, parks, squares, and schools. There are many types of fitness equipment on the market, such as treadmills, exercise bikes, parallel bars, and rowing machines. These types of equipment are mostly designed to help people relax and stretch their muscles during leisure time, thus achieving the purpose of exercise. However, the number of elderly people in my country is increasing year by year. People with hemiplegia, lower limb mobility impairments, and wrist and shoulder joint dysfunctions lack even the most basic usable and exercise equipment, making it impossible for them to access basic professional exercise equipment.
[0003] The existing kneading and pushing disc can rotate at a constant speed in the same or opposite directions, which can enhance joint mobility: it can significantly improve the mobility of the shoulder, elbow, wrist, hip, knee and other parts. However, when the kneading and pushing disc rotates, it is easy to cause accidental impact, which can lead to danger. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a kneading and pushing disc structure for fitness equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A kneading and pushing plate structure for fitness equipment includes a mounting rod, with kneading and pushing plates inclined at both ends of the mounting rod. Several mounting grooves are opened on one side of each of the two kneading and pushing plates, and ball bearings are rotatably installed in each of the several mounting grooves.
[0007] Preferably, the mounting rod is U-shaped, and mounting components are installed at both ends of the mounting rod. The kneading plate is installed at both ends of the mounting rod through the mounting components.
[0008] Preferably, the mounting assembly includes two mounting plates fixedly mounted at both ends of the mounting rod and several bolts that move through the mounting plates. The pushing and kneading plate has several threaded holes on one side, and the positions of the bolts correspond to the threaded holes.
[0009] Preferably, the mounting plate is circular.
[0010] Preferably, each of the mounting grooves covers half of the position of the ball bearing, and the ball bearing is made of environmentally friendly POM.
[0011] Preferably, the bottom of both kneading plates is provided with a plurality of drainage holes, and the plurality of drainage holes are connected to a plurality of mounting grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention, through the installation rod, can be welded to the device, allowing the user to stand naturally with legs slightly bent, hands firmly against the rolling balls, and perform rolling massage on two kneading and pushing plates, similar to the alternating kneading and pushing motions in Tai Chi. This exercises the shoulder muscles and enhances the flexibility and stability of the wrist and shoulder joints. In this way, the kneading and pushing plates do not need to rotate; the exercise is achieved solely through the rolling of the balls, reducing the risk of accidents and solving the problem of accidental impacts and dangers in existing technologies.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1 to 4 A kneading and pushing plate structure for fitness equipment includes a mounting rod 1, with kneading and pushing plates 2 inclinedly arranged at both ends of the mounting rod 1. Several mounting grooves 3 are opened on one side of each of the two kneading and pushing plates 2, and ball bearings 4 are rotatably installed in each of the several mounting grooves 3.
[0021] When using this device, the mounting rod 1 can be welded onto the instrument, allowing the user to stand naturally with legs slightly bent, hands firmly against the rolling balls 4, and perform rolling massage on the two kneading and pushing plates, similar to the alternating kneading and pushing motion of Tai Chi, to exercise the shoulder muscles and enhance the flexibility and stability of the wrist and shoulder joints. In this way, the kneading and pushing plates 2 do not need to rotate, and the exercise is only carried out by the rolling of the rolling balls 4, reducing the risk and solving the problem of accidental impact and danger in existing technologies.
[0022] Currently, the standard hand grip size for Tai Chi kneading and pushing products on the market is between 350mm and 550mm. Due to safety regulations and national standards regarding the anti-snagging gap between the conventional dimensions of the rotating discs, the width between the two discs is generally greater than 230mm. This product, taking into account the natural distance between the palms of the human body, calculates and determines the distance between the two massage discs to be 600mm, with the height controlled at 1200mm, meeting the exercise needs of normal people. In addition, referring to the angle of the massage contact surface of the wrist when the human body is standing, the kneading and pushing plate 2 is set at a 40° angle to maximize the contact surface of the touch massage and the optimal angle for force application.
[0023] Furthermore, the mounting rod 1 is U-shaped, and mounting components are installed at both ends of the mounting rod 1. The kneading plate 2 is installed at both ends of the mounting rod 1 through the mounting components. The mounting components include two mounting plates 5 fixedly installed at both ends of the mounting rod 1 and several bolts 6 that move through the mounting plates 5. Several threaded holes are opened on one side of the kneading plate 2, and the bolts 6 are positioned corresponding to the threaded holes. The mounting plate 5 is circular. Through the bolts 6, the bolts 6 can be threaded through the mounting plate 5 and connected to the threaded holes, so that the kneading plate 2 is installed on one side of the mounting plate 5. In this way, the kneading plate 2 will not rotate when the user uses it.
[0024] Furthermore, each of the aforementioned mounting grooves 3 covers half of the ball bearing 4, and the ball bearing 4 is made of environmentally friendly POM. By having the mounting grooves 3 cover more than half of the ball bearing 4, the ball bearing 4 can rotate during use and is also prevented from detaching from the mounting grooves 3. The use of environmentally friendly POM makes the ball bearing 4 environmentally friendly, aesthetically pleasing, lightweight, and textured, as well as waterproof, wear-resistant, aging-resistant, acid and alkali resistant, UV resistant, and has high strength.
[0025] Furthermore, both of the kneading plates 2 have several drainage holes 7 at their bottoms, and these drainage holes 7 are connected to several mounting grooves 3. Through the drainage holes 7, rainwater enters the mounting grooves 3 when it rains, allowing the rainwater to pass through the mounting grooves 3 and then flow out through the drainage holes 7, preventing rainwater from accumulating in the mounting grooves 3 and affecting the service life of the device.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
