DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide a body exercise device with intelligently adjustable force to solve the problems existing in the above-mentioned prior art, and to use an axis buffer to provide different damping forces of the exercise device, so that the damping force can be adjusted simply and conveniently with a high safety factor.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 5 As shown: This embodiment provides a body exercise equipment with intelligently adjustable force, including a bracket 1, a movable arm 3 and a handle 4. The bracket 1, the movable arm 3 and the handle 4 are two and symmetrically arranged. The bracket 1 is fixed vertically and can be fixed vertically on the ground, or a support can be set at the bottom to fix the bracket 1 vertically on the support. The movable arm 3 is rotatably connected to the bracket 1 through the shaft buffer 2. The maximum torque of the shaft buffer 2 can reach 90KG. The handle 4 is fixedly connected to the movable arm 3 for the exerciser to grab. A bench 5 is fixed between the two brackets 1 so that the exerciser can sit and exercise his arms to improve comfort.

[0027] The shaft buffer 2 includes a rotating shaft 8 and a sleeve 9. The movable arm 3 is rotatably connected to the bracket 1 through the rotating shaft 8. A blade 10 is fixedly connected to the rotating shaft 8. In this embodiment, there are two blades 10, and the two blades 10 are symmetrically fixed on the rotating shaft 8. The sleeve 9 sealing sleeve is arranged at one end of the rotating shaft 8. A damping liquid is injected between the sleeve 9 and the rotating shaft 8. The damping liquid has different viscosities. In this embodiment, the damping liquid is preferably silicone oil. The sleeve 9 is fixedly connected to the bracket 1. The sleeve 9 is fixedly connected to the bracket 1 through a first fixed sleeve 7. The rotating shaft 8 outside the bracket 1 is sleeved with a second fixed sleeve 6. One end of the sleeve 9 away from the movable arm 3 is fixedly connected to a base. The viscosity of the silicone oil is different. When the rotating shaft 8 rotates, the resistance of the silicone oil to the blade 10 is different. Therefore, the shaft buffer 2 with different damping forces can be prepared by using silicone oils of different viscosities. When different training weights are required, the shaft buffer 2 can be replaced to meet various training requirements. Replacement is quick and easy, completely avoiding the drawbacks of traditional methods of replacing counterweights or using expensive and unsafe electric equipment such as electric motors.

[0028] Specifically, the rotating shaft 8 is a stepped shaft, the rotating shaft 8 with a small diameter is rotatably connected to the bracket 1, and the rotating shaft 8 with a large diameter is fixedly connected to the movable arm 3 and rotatably connected to the shaft buffer 2. The top of the blade 10 is connected with a forward and reverse combination buckle 11, and the forward and reverse combination buckle 11 includes a front wall 13, a top wall 14 and a rear wall 15 which are vertically fixedly connected in sequence. The two ends of the top wall 14 are respectively fixed on the blade 10, and there is a gap between the front wall 13 and the rear wall 15 and the blade 10, so that the blade 10 can contact the front wall 13 and the rear wall 15. A front long strip slit is provided on the front wall 13, and a rear long strip slit is provided on the rear wall 15. The width of the front long strip slit is different from the width of the rear long strip slit, or the width of one of the front long strip slit and the rear long strip slit is set to zero. A liquid outlet can also be provided on the top wall 14, and the widths of the front long strip slit and the rear long strip slit are both smaller than the width of the liquid outlet. Two buckles 12 are provided on the inner side of the shaft sleeve 9. The buckles 12 match the clockwise and counterclockwise combination buckles 11. The angle between the two buckles 12 is 120°, which can realize the positioning of the shaft buffer 2 during clockwise and counterclockwise rotation. In this embodiment, the width of the front long strip slit on the front wall 13 is smaller than the width of the rear long strip slit and is zero. When the handle 4 is pushed backward, the movable arm 3 drives the rotating shaft 8 to rotate counterclockwise in the shaft buffer 2. At the same time, the blade 10 stirs the silicone oil. Under the extrusion resistance of the silicone oil, the blade 10 fits with the front wall 13. At this time, because the silicone oil being dialed cannot pass through the clockwise and counterclockwise combination buckle 11, the clockwise and counterclockwise combination buckle 11 plays the role of a paddle, so that the silicone oil produces a large extrusion damping force on the blade 10; on the contrary, when the handle 4 is pulled forward, the movable arm 3 The rotating shaft 8 is driven to rotate clockwise in the shaft buffer 2, and the blades 10 are stirring the silicone oil. Under the extrusion resistance of the silicone oil, the blades 10 fit against the rear wall 15, and the silicone oil enters from the rear long strip gap and flows out from the gap between the front wall 13 and the blades 10 or the liquid outlet on the top wall 14. At this time, since the rear long strip gap is larger, the silicone oil produces a certain flow, and the blades 10 produce a smaller damping force, thereby achieving a large resistance when pushing backwards and achieving the purpose of exercising the arms, and a small resistance when pulling forward, so that the movable arm 3 can be pulled back and reset with great effort.

[0029] It should be noted that, in this embodiment, a movable arm for leg movement and a movable arm for shoulder pulling up and down can be added to the rotating shaft, thus forming a three-in-one exercise device.

[0030] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
