DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-6 The utility model provides a technical solution: an arm strength training device, comprising an arm trainer body 1; handles 2, which are located at both ends of the arm trainer body 1 and are used by a user to grasp and pull the arm trainer body 1; a protection mechanism 3, which is located at one end of the handle 2 and is used to protect the safety of the user during exercise. The user holds the handles 2 at both ends of the arm trainer body 1 with both hands, and at the same time puts the protection mechanism 3 on the user's wrists, and uses both arms to pull the arm trainer body 1 to move to both ends. During the exercise, the user can be protected by the protection mechanism 3 to prevent the user from losing strength and losing the arm trainer body 1 during exercise, so that the arm trainer body 1 rebounds and accidentally injures the user, causing a safety hazard to the user, which is beneficial for the user to perform daily exercise tasks.

[0023] The protection mechanism 3 includes an airbag 30 fixedly connected to the inner wall of the handle 2. The airbag 30 is elastic and can squeeze the gas inside the airbag 30 into the conduit 31 when pressed, and re-inhale the air in the conduit 31 after recovering and rebounding. One end of the airbag 30 is fixedly connected to the conduit 31, so that the air in the airbag 30 will not leak out after being squeezed out manually. The inner wall of the conduit 31 is slidably connected to a guide rod 32, which can reciprocate on the inner wall of the conduit 31 under the pressure of the air in the airbag 30. The inner wall of the handle 2 is slidably connected to a first ratchet 33, which can be used in conjunction with a second ratchet 35 to prevent the second ratchet 35 from reversing. The lower end of the first ratchet 33 is fixedly connected to a spring 34, so that when the second ratchet 35 slides on the surface of the first ratchet 33, the second ratchet 35 The spring 34 is squeezed, and under the reaction of the spring 34, the second ratchet 35 makes a reciprocating motion on the inner wall of the handle 2. The spring 34 is fixedly connected to the inner wall of the handle 2. The surface of the first ratchet 33 is slidably connected with the second ratchet 35, which can slide on the surface of the first ratchet 33 to control the rotation direction of the cylinder 36. The second ratchet 35 is rotatably connected to the inner wall of the handle 2. The end of the second ratchet 35 away from the first ratchet 33 is fixedly connected with the cylinder 36, which can be wound around the length of the contracted long rope 37 so that the length of the long rope 37 can adapt to the wrists of different users. The surface of the cylinder 36 is wound with the long rope 37, which can be wound around the wrist of the user to fix the arm trainer body 1 on the wrist of the user, which can prevent the arm trainer body 1 from slipping out of the hand and accidentally injuring the user. The long rope 37 is slidably connected to the inner wall of the handle 2;

[0024] The user wraps the long rope 37 around the wrist and holds the handle 2 tightly, so that the airbag 30 is squeezed and deformed, and the air in the airbag 30 is squeezed into the catheter 31, pushing the guide rod 32 to move in the catheter 31. When the user pulls the length of the long rope 37, the cylinder 36 rotates clockwise and drives the second ratchet 35 to slide on the surface of the first ratchet 33, so that the first ratchet 33 slides linearly on the inner wall of the handle 2 and squeezes the spring 34 at the same time. Under the reaction of the spring 34, the second ratchet 35 repeatedly contacts and separates from the first ratchet 33.

[0025] The guide rod 32 forms a sealing area 38 with the airbag 30 on the inner wall of the catheter 31, which can prevent the gas in the airbag 30 from dissipating in the sealing area 38, resulting in insufficient air pressure in the airbag 30, affecting the normal recoverable deformation of the airbag 30. The end of the guide rod 32 away from the airbag 30 is fixedly connected to the first trapezoidal block 39, which can contact and squeeze the second trapezoidal block 313 when the airbag 30 is restored, so that the first ratchet 33 is fixed to the inner wall of the handle 2 and will not move linearly on the inner wall of the handle 2. When the user squeezes the airbag 30, the first trapezoidal block 39 is separated from the second trapezoidal block 313, so that the second ratchet 35 can slide on the surface of the first ratchet 33, and the first ratchet 33 can squeeze the spring 34 and move linearly on the inner wall of the handle 2. After the airbag 30 recovers its deformation, the first trapezoidal block 39 contacts the second trapezoidal block 313, so that the second ratchet 35 is fixed on the surface of the first ratchet 33, and the first ratchet 33 is fixed to the inner wall of the handle 2.

[0026] A limit block 310 is provided on the surface of the first ratchet tooth 33, which can be used in conjunction with the limit groove 311, so that the first ratchet tooth 33 can slide linearly along the limit groove 311 on the inner wall of the handle 2. The limit groove 311 is provided on the inner wall of the handle 2, which can prevent the first ratchet tooth 33 from rotating on the inner wall of the handle 2 under the pressure of the second ratchet tooth 35. The limit groove 311 is slidably connected with the limit block 310. An arc plate 312 is provided at the lower end of the first ratchet tooth 33, which can make the first trapezoidal block 39 move in the inner wall of the arc plate 312, and make the first trapezoidal block 39 contact and separate with the second trapezoidal block 313, and the arc plate 312 can be used to prevent the first ratchet tooth 33 from rotating on the inner wall of the handle 2 under the pressure of the second ratchet tooth 35. A second trapezoidal block 313 is symmetrically provided at the lower end of the arc plate 312, which can contact the first trapezoidal block 39 to limit the first ratchet 33 from sliding along the limiting groove 311 on the inner wall of the handle 2. The second trapezoidal block 313 is slidably connected to the first trapezoidal block 39. When the airbag 30 is squeezed, the first trapezoidal block 39 slides on the inner wall of the arc plate 312 and separates from the second trapezoidal block 313. When the airbag 30 recovers its deformation, the first trapezoidal block 39 moves in the opposite direction on the inner wall of the arc plate 312, contacts the second trapezoidal block 313, and limits the first ratchet 33 from moving linearly on the inner wall of the handle 2.

[0027] The inner wall of the cylinder 36 is fixedly connected with a retaining spring 314, which can make the cylinder 36 rotate counterclockwise to shorten the length of the long rope 37, which is helpful for the user to adjust the length of the long rope 37 and exercise better. The retaining spring 314 is fixedly connected to the inner wall of the handle 2, and the cylinder 36 is rotatably connected to the inner wall of the handle 2.

[0028] One end of the long rope 37 is fixedly connected to a ring 315 , so that one end of the ring 315 can slide along the long rope 37 to fix the user's wrists at both ends of the arm trainer body 1 , and the ring 315 is sleeved on the surface of the long rope 37 .

[0029] Embodiment 2

[0030] A safety zone 316 is set between the ring 315 and the connection position of the long rope 37. After contacting the user's wrist, if the arm trainer body 1 slips out of the hand, the safety zone 316 can shrink and fix one end of the long rope 37 to the user's wrist to prevent the arm trainer body 1 from slipping out of the hand and accidentally injuring the user. The inner wall of the safety zone 316 is provided with a wide cloth 317, which can form a larger contact area with the user's wrist to prevent the safety zone 316 from suddenly shrinking and causing damage to the wrist.
