Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to an explosive force training equipment. Background Art

[0002] Explosive power refers to the ability to exert maximum force in the shortest time. It is a rapid force output and is usually closely related to speed and strength. Explosive power training equipment is a device that can help athletes improve their muscles' rapid force output ability.

[0003] However, most of the explosive power training equipment currently available on the market can only train one of the lower limbs or upper limbs, making the explosive power training program relatively single and unbalanced. In addition, most of the explosive power training equipment currently available on the market is not convenient for adjusting the training intensity of the equipment, and cannot be adjusted in a targeted manner according to the physical condition of the trainee, resulting in poor training effect.

[0004] Therefore, those skilled in the art provide an explosive force training device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the existing technology and to propose an explosive power training device. The first elastic band in the motion mechanism is used to tighten the support slider, and the second elastic band is used to tighten the stretching rod to achieve lower limb and upper limb training. By shaking the first crank and the second crank in the adjustment mechanism, the tightness of the first elastic band and the second elastic band is changed, thereby changing the training intensity.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0009] Furthermore, a threaded rod is rotatably connected to the middle part of the inner wall at the rear end of the adjusting groove, the front end of the threaded rod passes through the base and is fixedly connected to the first crank, one side of the outer wall at the front end of the base is threadedly connected to the first bolt, the rear end of the outer wall of the threaded rod body is threadedly connected to the adjusting block, the rear end of the second elastic band is fixedly connected to the storage wheel, the upper end of the storage wheel passes through the connecting rod and is fixedly connected to the second crank, and the rear end of the upper end of the connecting rod is threadedly connected to the second bolt;

[0010] Through the above technical solution, by shaking the first crank in the adjustment mechanism, the threaded rod is driven to rotate, and the adjustment block threadedly connected to the threaded rod slides inside the adjustment groove, thereby changing the tightness of the first elastic band, and thus changing the intensity of the lower limb training. By shaking the second crank, the storage wheel is driven to rotate, the second elastic band is rolled up, and the tightness of the second elastic band is changed, thereby changing the intensity of the upper limb training.

[0011] Furthermore, the supporting slider slides inside the slide groove, and the cross bars slide inside the slide groove;

[0012] Through the above technical solution, the supporting slider and the cross bar slide inside the slide groove, so that when the athlete performs leg force during lower limb training, the supporting slider and the cross bar can be pushed, making the movement smoother.

[0013] Furthermore, the upper end of the supporting slider is fixedly connected to a seat, and the outer walls on both sides of the seat are fixedly connected to armrests;

[0014] Through the above technical solution, by supporting the seat fixedly connected to the slider and the armrests on both sides of the seat, athletes can sit on the seat and hold the armrests with their hands when performing lower limb training, thereby improving the stability of training. During the halftime break, the seat can also allow athletes to relax their lower limbs and rest.

[0015] Furthermore, both sides of the front end of the upper end of the base are fixedly connected with pedals, and the upper ends of the support columns are fixedly connected with limit blocks;

[0016] Through the above technical solution, the athlete sits on the chair with his back leaning against the chair back and his feet placed on the two pedals fixedly connected to the base, which facilitates the athlete's leg exertion and performs lower limb training. The limit block fixedly connected to the upper end of the support column can prevent the stretching rod from excessive reverse movement under the action of the second elastic band, thereby preventing the athlete from hitting the athlete, thereby reducing training risks.

[0017] Furthermore, the avoidance grooves are connected to the adjustment grooves and the sliding grooves, and the adjustment blocks slide inside the adjustment grooves;

[0018] Through the above technical solution, the avoidance groove is connected with the adjustment groove and the sliding groove, so that the first elastic band can pass through the avoidance groove and be fixed to the adjustment block, and then the adjustment block can move inside the adjustment groove under the drive of the rotating threaded rod, thereby changing the tightness of the first elastic band fixedly connected to the adjustment block.

[0019] Furthermore, the first bolt is connected to the first crank by a clamping connection, and the second bolt is connected to the second crank by a clamping connection;

[0020] Through the above technical solution, the first bolt and the second bolt are respectively connected to the first crank and the second crank, so that after shaking the first crank and the second crank to adjust the tightness of the first elastic band and the second elastic band to the required requirements, the first bolt and the second bolt can be used to fix the first crank and the second crank to prevent the first crank and the second crank from rotating.

[0021] Furthermore, the front ends of the first elastic bands all pass through the avoidance grooves and are fixedly connected to the adjustment blocks, and the connecting rods are all rotatably connected to the storage wheels;

[0022] Through the above technical solution, the first elastic band passes through the avoidance groove and is fixedly connected to the adjustment block, so that the adjustment block sliding inside the adjustment groove can stretch or relax the first elastic band, and the second elastic band can be rolled up on the storage wheel by using the storage wheel rotatably connected to the connecting rod to achieve stretching or relaxing the second elastic band.

[0025] 2. The utility model proposes an explosive power training device, which drives the threaded rod to rotate by shaking the first crank in the adjustment mechanism, allowing the adjustment block threadedly connected to the threaded rod to slide inside the adjustment groove, thereby changing the tightness of the first elastic band and thus changing the intensity of the lower limb training. By shaking the second crank, the storage wheel is driven to rotate, the second elastic band is rolled up, the tightness of the second elastic band is changed, and thus the intensity of the upper limb training is changed, so that targeted adjustments can be made according to the physical condition of the trainee, which is conducive to improving the training effect.
