The specific implementation mode is as follows:

referring to the figures, the paddle damping type competition starting strength trainer comprises a box body 4, a long shaft 10, a transverse long shaft 10 in the box body 4, an oil tank 11, a paddle wheel 12, a large rope winder 13, a small rope winder 14 and an automatic rewinding spring 20 are arranged on the long shaft 10 in a penetrating mode, six rectangular paddles are uniformly distributed on the paddle wheel 12 and are arranged in the oil tank 11, a traction rope 2 is wound on the large rope winder 13 and the small rope winder 14, one end of the traction rope 2 is fixed on the large rope winder 13 and the small rope winder 14 respectively, the other end of the traction rope 2 penetrates through a rope outlet guide hole 6 and extends to the outside of the box body 4, the rope outlet guide hole 6 is arranged on the side wall of the box body 4, the traction rope 2 is connected with one end of a connecting and fixing section 3 respectively, and the other end of the connecting and fixing section 3 is connected with a double-span shoulder belt 1. The paddle wheel 12, the large rope winder 13, the small rope winder 14 and the automatic rewinding spring 20 are fixed on the long shaft 10 through key slots. The oil tank 11 is internally provided with gear oil. The oil storage tank 15 is arranged in the tank body 4, the oil storage tank 15 is arranged below the large rope winder 13 and the small rope winder 14, the oil storage tank 15 is connected with the oil tank 11 through two oil pipes 18, an oil level reset bolt 19 is arranged on one oil pipe 18, a one-way hand-pressed oil pump 17 is arranged on the other oil pipe 18, and an oil nozzle cap 16 is arranged on the oil storage tank 15. A pull spring 21 is arranged at the joint of the tail end of the traction rope 2 and the large rope winder 13 and the small rope winder 14. And sealing stuffing boxes 9 are arranged at the joints of the oil tank 11 and the two ends of the long shaft 10. The rope outlet guide hole 6 is formed in the side wall of the box body 4, and a guide hole reinforcing plate 7 is arranged at the rope outlet guide hole 6. The box body 4 is provided with a box cover 8 with a detachable shell, and four corners of one side wall of the box body 4 are provided with base angles 5.

The paddle damping type competition starting strength trainer is arranged in a cuboid shell box body 4 and is provided with a paddle wheel 12, a large rope winder 13, a small rope winder 14, an automatic rewinding spring 20, an oil tank 11 and an oil storage tank 15. Wherein 6 rectangular paddles are uniformly distributed on the paddle wheel 12 and are arranged in the oil tank 11, the paddle wheel, the large rope winder 13, the small rope winder 14 and the automatic rewinding spring 20 are fixed on the long shaft 10 through key slots, and a certain amount of gear oil is stored in the oil tank 11. An oil storage tank 15 is arranged at the corner below the large rope winder 13 and the small rope winder 14 and is connected with the oil tank 11 through an oil pipe 18, a one-way hand-pressure oil pump 17 and an oil level reset bolt 19.

The traction rope 2 adopts a reinforced wear-resistant flat woven belt which can bear large force, and the tail end of the traction rope is provided with a pull spring 21.

The one-way hand-pressed oil pump 17, the oil level reset bolt 19, the automatic rollback spring 20 and the sealing stuffing box 9 are various finished products which can meet the requirements of the invention, and the invention is only selected.

The large rope winder 13 and the small rope winder 14 are wound on the traction rope 2 and extend to the outside of the case 4 along the rope outlet guide hole 6, and are connected with the double-shoulder harness 1 through a connecting and fixing section. The guide hole reinforcing plate 7 at the rope outlet guide hole 6 is made of PP materials so as to reduce the abrasion of the double-straddle shoulder harness 1.

The position of the long shaft 10 penetrating through the box wall of the box body 4 is provided with a sealing stuffing box 9, and a mechanical sealing ring is arranged in the sealing stuffing box, so that the sealing stuffing box can be used for supporting the long shaft 10 and lubricating the long shaft 10.

When the automatic rewinding device is used, the traction rope 2 is pulled outwards to drive the long shaft 10 to rotate, the blades of the paddle wheel 12 stir gear oil in the oil tank 11, and the automatic rewinding spring 20 starts to be gradually tightened. When the traction rope 2 is loosened, the device is driven to reset under the action of the automatic rewinding spring 20, and the traction rope 2 is wound back.

When the resistance needs to be reduced, the oil level returning bolt 19 is opened, and the oil in the oil tank 11 flows into the oil reservoir 15 by gravity. The oil storage tank 15 is provided with an oil nozzle cap 16, which can open the air bleed to accelerate the flow and also can supplement oil products.

The automatic rewinding spring 20 is adopted, because of the viscous action of gear oil and the weight inertia of each wheel disc, the speed of recovering the mesh belt is very low, manual operation and control are convenient, and people cannot be hurt by bouncing due to too high speed.

The paddle damping type competition starting strength trainer is used by falling on the ground by adopting a metal box body 4. Adopt rag bolt fixed when carrying out the exercise of big dynamics, can provide the training of two kinds of run-off distances of length. The training can be performed on any field, and the training can be performed by one person or by a plurality of persons in combination of instruments, so that the training device is suitable for relevant training on any scale and under any condition.

The invention fully utilizes the principle of the plectrum damper and the viscous characteristic of gear oil, and adds the inertia of each wheel disc (rope winder) and the resistance of the automatic rewinding spring, so that the invention has only general dragging feeling during the run-off preparation, and the resistance is the largest during the run-off initial, at this time, the invention can fully exercise the strength of quadriceps femoris muscle, popliteal muscle, hip flexor, gluteus muscle and calf muscle of the human body, and has great strengthening effect on the ligament strength of the related muscle groups.

After the running-starting moment, each wheel disc has certain kinetic energy and inertia, the resistance of the plectrum in oil is weakened to a certain extent, and the speed of the second stage of running-starting is improved to a certain extent.

Near the normal running phase, the resistance drops to a minimum and the relevant muscle group enters the speed sensation and begins the speed exercise. Because speed training can be completed in other ways, the invention is only used as adaptive training in this stage, the process is short, namely the total length of the traction rope is not too long, the three stages of actions are completely completed, and the length of the traction rope is not more than 20 meters. If only two stages before starting, a short hauling rope is adopted, generally not more than 10 meters is adopted, and only a few steps of the outbreak starting action are completed. Meanwhile, the diameter of the short rope wheel disc is smaller, the power distance is shortened, and the strength training effect is more obvious.

In order to ensure that quick-motion personnel are not mechanically damaged by the traction rope after the rope is completely discharged, the tail end of the traction rope is provided with a pull spring, and the force of the traction rope is relieved by the elasticity of the pull spring.

In summary, the paddle damping type competition starting strength trainer mainly provides strength required by training of all items including starting actions through damping action, can be used for starting training in competition items, can also be used for starting high jump and throwing items of field competition items, and can also be used for body building.
