Description

Technical Field

[0001] The present application relates to the technical field of sports training equipment, and in particular to a shot put throwing trainer. Background Art

[0002] The shot put throwing trainer is an auxiliary device specially used to improve the shot put throwing skills. It can help athletes to practice skills and strength training without coaches or teammates. Most of the existing shot put throwing trainers are composed of an inclined guide rod and a simulated shot put sliding on the guide rod. During training, athletes hold the simulated shot put and throw it. The simulated shot put slides upward on the outer side of the guide rod. After the kinetic energy of the simulated shot put is completely converted into gravitational potential energy, the simulated shot put immediately slides down along the outer side of the guide rod and returns to the bottom.

[0003] Specifically, during use, the simulated shot put accelerates during its descent. If an athlete stands still at the throwing location, the high-speed returning shot put can easily injure him. At the same time, the inclination angle of the guide rod on the existing shot put throwing trainer cannot be adjusted, which is very inconvenient to use. Summary of the invention

[0004] The present application provides a shot put throwing trainer, which can adjust the inclination angle of the guide rod according to the height of the user, effectively improving the convenience of use. At the same time, the simulated shot put can be decelerated by a damper during the return process, thereby avoiding the simulated shot put returning at a high speed from injuring the operator, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a shot put throwing trainer, comprising two symmetrically arranged hollow bases; a hollow vertical pole is provided on the upper surface of the hollow base, a screw is threadedly connected to the upper end of the inner side surface of the hollow vertical pole, the upper end surface of the screw is rotatably connected to a hinge support, a slide rail is provided between the two hinge supports, the outer side surface of the slide rail is slidably connected to a sliding mechanism, and the sliding mechanism is connected to a simulated shot put through a support arm arranged on its outer side surface.

[0006] The sliding mechanism includes an outer shell, the inner side surface of the outer shell is rotatably connected to a positioning wheel, the number of the positioning wheels is not less than four, and the not less than four positioning wheels are arranged closely against the outer side surface of the slide rail, the inner side surface of the outer shell is provided with a damping mechanism, the damping mechanism includes a slide groove arranged on the inner side surface of the outer shell, the inner side surface of the slide groove is slidably connected to a slider, the slide rail is inclined, a spring is arranged at the lower end of the inner side surface of the slide groove, the outer side surface of the slider is rotatably connected to a brake shaft, the outer side surface of the brake shaft is rotatably connected to a brake roller, the brake roller is arranged closely against the outer side surface of the slide rail, a brake pad is arranged inside the outer shell near the slide groove, the brake pad and the spring are respectively arranged on both sides of the brake shaft, and the brake pad is arranged above the spring.

[0007] Preferably, a detachable cover is provided on the outer side surface of the hollow base, and handles are provided at both the front and rear ends of the upper surface of the hollow base.

[0008] Preferably, the outer side surface of the hollow upright pole is connected to the upper surface of the hollow base via a triangular support frame, and the lower end surface of the hollow upright pole is connected to the upper surface of the hollow base via a mounting seat.

[0009] Preferably, the outer side surface of the screw rod is linearly and evenly distributed with adjustment holes from top to bottom.

[0010] Preferably, a baffle is slidably connected to the outer side surface of the slide rail.

[0011] Preferably, the baffle is provided with a stud, and the end of the stud is tightly pressed against the outer side of the slide rail.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This shot put throwing trainer can adjust the inclination of the guide rod according to the height of the user, which effectively improves the convenience of use. At the same time, the simulated shot put can be decelerated by the damper during the return process, thereby preventing the simulated shot put from hitting the operator during the high-speed return process;

[0014] 2. The user holds the simulated shot put and pushes it out. Pushed by the user, the simulated shot put drives the sliding mechanism to slide upward along the slide rail. While the outer shell slides upward, the brake roller drives the slider downward and contacts the spring under the action of friction. At this time, the friction resistance acting on the brake shaft is small. When the simulated shot put drives the sliding mechanism to slide downward along the slide rail for the return journey, the brake roller drives the slider upward under the action of friction. At this time, the brake shaft contacts the brake pad, and the friction resistance acting on the brake shaft increases greatly. At this time, the friction between the brake roller and the slide rail increases greatly, and the downward acceleration of the simulated shot put is significantly reduced, which can effectively prevent the simulated shot put from injuring the operator.

[0021] See also Figure 1-3 The present application provides the following technical solutions: a shot put throwing trainer, comprising two symmetrically arranged hollow bases 3; a hollow vertical rod 5 is provided on the upper surface of the hollow base 3, a screw rod 7 is threadedly connected to the upper end of the inner side surface of the hollow vertical rod 5, and a hinge support is rotatably connected to the upper end surface of the screw rod 7, a slide rail 12 is provided between the two hinge supports, and a sliding mechanism 10 is slidably connected to the outer side surface of the slide rail 12, and the sliding mechanism 10 is connected to a simulated shot put 8 through a support arm 11 arranged on its outer side surface.

[0022] Specifically, the slide rail 12 is rotatably connected to the hinge support, and the simulated shot put 8 can reciprocate along the slide rail 12 under the thrust of the user, which can effectively improve the training efficiency.

[0024] Specifically, the user holds the simulated shot put 8 and pushes it out. The simulated shot put 8 drives the sliding mechanism 10 to slide upward along the slide rail 12 under the push of the user. While the outer shell 104 slides upward, the brake roller 102 drives the slider 108 to move downward under the action of friction and contact with the spring 101. At this time, the friction resistance acting on the brake shaft 105 is small.

[0025] More specifically, when the simulated shot put 8 drives the sliding mechanism 10 to slide downward and return along the slide rail 12, the brake roller 102 drives the slider 108 to move upward under the action of friction. At this time, the brake shaft 105 contacts the brake pad 103, and the friction resistance acting on the brake shaft 105 is greatly increased. At this time, the friction force between the brake roller 102 and the slide rail 12 is greatly increased, and the downward acceleration of the simulated shot put 8 is significantly reduced, which can effectively prevent the simulated shot put 8 from injuring the operator.

[0028] Furthermore, the outer side surface of the hollow upright pole 5 is connected to the upper surface of the hollow base 3 through the triangular support frame 4, and the lower end surface of the hollow upright pole 5 is connected to the upper surface of the hollow base 3 through the mounting seat 2.

[0032] Furthermore, a baffle 9 is slidably connected to the outer side surface of the slide rail 12 .

[0033] Specifically, the position of the baffle 9 can be adjusted, and the baffle 9 is used to limit the stroke of the simulated shot put 8.

[0034] Furthermore, the baffle plate 9 is provided with a stud, and the end of the stud is tightly pressed against the outer side surface of the slide rail 12 .

[0035] Specifically, the locking studs can fix the position of the baffle 9.

[0036] When in use: when adjusting the height of the screw rod 7 , the adjustment rod is inserted into the adjustment hole 6 , and the screw rod 7 can be rotated by the adjustment rod, so as to control the lifting and lowering of the screw rod 7 , thereby realizing the tilting adjustment of the slide rail 12 .

[0037] During training, the user holds the simulated shot put 8 and pushes it out. The simulated shot put 8 drives the sliding mechanism 10 to slide upward along the slide rail 12 under the push of the user. While the outer shell 104 slides upward, the brake roller 102 drives the slider 108 to move downward under the action of friction and contact with the spring 101. At this time, the friction resistance acting on the brake shaft 105 is small.

[0038] When the simulated shot put 8 drives the sliding mechanism 10 to slide downward and return along the slide rail 12, the brake roller 102 drives the slider 108 to move upward under the action of friction. At this time, the brake shaft 105 contacts the brake pad 103, and the friction resistance acting on the brake shaft 105 is greatly increased. At this time, the friction force between the brake roller 102 and the slide rail 12 is greatly increased, and the downward acceleration of the simulated shot put 8 is significantly reduced, which can effectively prevent the simulated shot put 8 from hitting the operator.
