Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, an arm bending and stretching exercise frame for exercise and muscle strain prevention comprises a frame 1, a seat cushion 2 fixedly connected to the front of the frame 1, the frame 1 and the seat cushion 2 fixedly connected through a T-shaped support 19, a rotating shaft 5 rotatably connected to the top of the frame 1, a back cushion 3 fixedly connected to the front of the frame 1, a steering wheel 9 fixedly connected to the inner wall of the frame 1 below a speed reduction fluted disc 12, a wire coil 6 sleeved on the outer wall of the rotating shaft 5, a pull rod 4 fixedly connected to the bottom axis of the wire coil 6, a speed reduction wheel 18 fixedly connected to the back of the frame 1, a speed reduction shaft 11 sleeved inside the speed reduction wheel 18, a speed reduction fluted disc 12 fixedly connected to the left end of the speed reduction shaft 11, a fixed frame 10 fixedly connected to the front of the speed reduction fluted disc 12, a chute 16 formed in the front of the fixed frame 10, a non-newton liquid contained in the, the front face of the reduction gear 13 is rotatably connected with a reduction connecting rod 14, the reduction gear 13 and the reduction connecting rod 14 are rotatably connected through a fixing shaft 17, the bottom end of the reduction connecting rod 14 is rotatably connected with a sliding block 15, the bottom end of the back face of the rack 1 is fixedly connected with a counterweight cabin 7, and the counterweight cabin 7 is slidably connected with a counterweight block 8.

The working principle is as follows: when the balance weight cabin 7 is connected with a proper balance weight block 8 and sits on the seat cushion 2 after being connected with a steel wire rope, the arm tightens the pull rod 4 to stretch and close, the pull rod 4 drives the wire coil 6 to pull the steel wire rope with one end fixed on the wire coil 6 to be meshed with or separated from a wire groove of the wire coil 6, when the balance weight block 8 drives the steel wire rope to rapidly fall due to improper operation or insufficient strength, the steel wire rope drives the speed reducing wheel 18 to rapidly rotate clockwise, the speed reducing wheel 18 drives the speed reducing shaft 11 fixedly connected with the speed reducing wheel 18 to rapidly rotate clockwise, the speed reducing shaft 11 drives the speed reducing gear 13 to rapidly rotate clockwise so as to drive the speed reducing connecting rod 14 rotationally connected to the front side of the speed reducing gear 13 to rapidly pull the sliding block 15 to rapidly slide in the sliding groove 16, the sliding block 15 rapidly extrudes non-Newtonian liquid in the sliding groove 16, the condensed non-Newtonian liquid provides, the reduction gear 13 slows down the slew velocity of

reduction shaft

11, and 18 rotational speeds of the reduction gear of being connected with reduction shaft 11 fixed slow down, and the many wire ropes of 18 wire casing internal thread of reduction gear block wire rope's slip with great frictional force to prevent or slow down the whereabouts of balancing weight 8, avoid pulling user's muscle.

In conclusion, according to the arm bending and stretching exercise frame for body building and muscle strain prevention, the steel wire rope falls rapidly to drive the speed reducing wheel 18 to rotate rapidly, so as to drive the speed reducing gear 13 fixedly connected with the speed reducing wheel 18 to rotate rapidly, the speed reducing gear 13 rotates to drive the speed reducing connecting rod 14 to pull the sliding block 15 to slide in the sliding groove 16, the sliding block 15 moving rapidly impacts non-Newtonian liquid in the sliding groove 16, the condensed non-Newtonian liquid provides certain counter braking power for the sliding block 15, and the speed reducing wheel 18 brakes the steel wire rope, so that the rapidly falling balancing weight 8 is prevented from strain muscles; the wire coil 6 which is fixedly connected with the pull rod 4 is driven to rotate by stretching the pull rod 4 through the arm to pull the steel wire rope fixed with the balancing weight 8, the pull rod 4 which limits the degree of freedom can only swing along the specified direction, muscles at the specified position can be effectively exercised, and the body-building forming effect is good.

Having shown and described embodiments of the present invention, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
