Description

waist exercise chair

technical field

The invention relates to a seat capable of exercising the waist, in particular to a sports seat which is movable and drives the waist to be exercised.

Background technique

The existing seat is fixed, and only has the effect of protecting the waist, and cannot realize the purpose of exercising.

Even if it is purely electric, it is not environmentally friendly and cannot exercise other parts of the body.

Contents of the invention

The technical problem to be solved by the present invention is to provide a waist exercising chair with simple structure, which can be used as an ordinary seat and has the function of exercising.

A waist exercise chair, characterized in that it includes a seat base, a first bevel gear rotating shaft vertically installed on the seat base, and a first bevel gear installed on the first bevel gear rotating shaft, and the seat base is eccentrically installed through the seat rotating shaft on the end face of the first bevel gear; it also includes a pulley shaft vertically installed on the first bevel gear shaft through a bearing; it also includes a third pulley, a fourth pulley, and a second bevel gear fixedly installed on the shaft, wherein the second bevel gear It is engaged with the first bevel gear; it also includes a first pulley and a second pulley respectively located on both sides of the rotating shaft installed on the seat base, and a first seat rocker which is fixedly connected with the first pulley and the second pulley respectively, The second seat rocker; the first pulley is connected to the third pulley through the first belt, the second pulley is connected to the fourth pulley through the second belt, and only one of the first belt and the second belt is Cross installation.

The invention is a waist exercising chair with simple structure, which can be used as an ordinary seat and has an exercising function. The seat support shaft is eccentrically installed on the bevel gear, and the bevel gear rotates the seat around the center of the bevel gear to achieve the purpose of seat swing. The bevel gear rotation is driven by the handle, and the driving speed of the handle determines the amplitude and speed of the seat swing. , so it also exercises the coordination ability of the arms and body.

The above-mentioned first pulley is connected with the first pulley fixed pillar fixedly installed on the seat base through the first pulley rotating shaft.

The above-mentioned second pulley is connected with the second pulley fixed support fixedly installed on the seat base through the second pulley rotating shaft.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a three-dimensional schematic diagram of a seat capable of exercising the waist. The rotation of the second seat rocker 3 and the first seat rocker 2 drives the second bevel gear 6 to rotate through the rotation of the first pulley 5 and the second pulley 7, and the second bevel gear 6 meshes with the first bevel gear 4, The rotation of the first bevel tooth 4 makes the seat 1 move.

Seat shown in Fig. 2,3,4,5,6,7 comprises seat base 8, rotating shaft 9, the 3rd pulley 10, the 4th pulley 11, the first belt 12, the second belt 13, the first bevel tooth rotating shaft 14, seat rotating shaft 15, the first pulley fixed pillar 16, the second pulley fixed pillar 17, the first pulley rotating shaft 18, the second pulley rotating shaft 19. In the present invention, the center of the second pulley 7 has a through hole, the first seat rocker 2 and the second pulley 7 are fixedly installed on the second pulley shaft 19, and the second pulley shaft 19 is installed on the second pulley fixed pillar 17 and the second pulley The second pulley rotating shaft 19 can rotate freely, and the second pulley fixing pillar 17 is fixedly installed on the seat base 8 . The second belt 13 connects the second pulley 7 and the third pulley 10 in a cross transmission manner, and the third pulley 10 is fixedly mounted on the rotating shaft 9 through a hole in the center. The center of the first pulley 5 has a hole, the second seat rocker 3 and the first pulley 5 are fixedly installed on the first pulley shaft 5, the first pulley shaft 18 is installed on the first pulley fixed pillar 16 and the first pulley shaft 18 It can rotate freely, and the first pulley fixing pillar 16 is fixedly installed on the seat base 8 . The first belt 12 connects the first pulley 5 and the fourth pulley 11 in a parallel transmission manner, and the fourth pulley 11 is fixedly mounted on the rotating shaft 9 through a hole in the center. The second bevel gear 6 is fixedly installed on one end of the rotating shaft 9, and the rotation of the rotating shaft 9 makes the second bevel gear 6 rotate simultaneously. The other end of the rotating shaft 9 is sleeved on the first bevel gear rotating shaft 14, and the side of the first bevel gear rotating shaft 14 has a hole, and the rotating shaft 19 can rotate freely in the first bevel gear rotating shaft 14. The first bevel teeth 4 and the second bevel teeth 6 mesh with each other, and the rotation of the second bevel teeth 6 makes the first bevel teeth 4 rotate synchronously. The seat 1 and the first bevel teeth 4 adopt an eccentric design, and the rotation of the first bevel teeth 4 moves the seat, thereby achieving the purpose of exercising the waist.
