Description

Technical Field

[0001] The utility model relates to the technical field of sports training tools, in particular to a novel track and field springboard. Background Art

[0002] Track and field jumping events include high jump, long jump, triple jump and pole vault. It is the oldest sport and an Olympic event. Jumping is a basic survival skill for humans. As a modern track and field sport, high jump and long jump are especially easy to learn, have strong appeal, help develop athletic abilities such as strength, speed, bounce, coordination and agility, and have little dependence on venues and equipment. They have become compulsory items in physical education courses at all levels of schools, favorite fitness items for the public, and training items for competitive competitions. Currently, the main auxiliary training equipment for take-off is the springboard.

[0003] In the prior art: a Chinese patent document with publication number: CN216497222U and publication date of May 13, 2022 is proposed. The technical solution disclosed in the patent document is as follows: it includes a base plate and a slot, a slot is provided on one side of the base plate, and rotating rods are provided at both ends of the slot. Each rotating rod is provided with a rotating seat, and a limit plate is inserted under each rotating seat. A groove is provided under the corresponding position of each limit plate, and a support seat is provided on each rotating seat, and a conical spring is provided on each support seat. By setting the device, the components do not need to be disassembled when carrying, which reduces the labor intensity of personnel.

[0004] The structure of common springboards is relatively simple, consisting of a base plate placed at the bottom and a pedal for assisting jumping. The pedal uses multiple sets of springs for jumping. In the above technology, the pedal and the base plate are connected by conical springs, so as to play an auxiliary role in sports training such as long jump. However, if only a single spring structure is used at a high frequency, the spring is prone to fatigue and affects the use of the entire springboard. Therefore, a structure that can assist the spring in jumping is required, and the spring can be quickly disassembled and installed. Therefore, if the spring is damaged when using the springboard, it is not necessary to replace the entire springboard. Therefore, a new track and field springboard is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-5The utility model provides a technical solution: it includes a bottom plate 1, the bottom plate 1 is an I-shaped structure, a stepping plate 2 is glued to one end of the top of the bottom plate 1, the stepping plate 2 is an arc plate, one end of which is in contact with the bottom plate 1, and the other end is on the same horizontal plane as the other end of the bottom plate 1, the bottom plate 1 and the stepping plate 2 are made of wood, which has good bounce and stability, and a support pad 8 made of rubber material is glued to the four corners of the bottom of the bottom plate 1, and a plurality of rows of round holes are opened at the bottom of the support pad 8, and the friction with the ground can be increased by utilizing the characteristics of its structure and material, thereby improving the stability of the springboard, and a layer of stepping pad 9 is wrapped on the top surface of the stepping pad 2, and the material of the stepping pad 9 is felt. When the trainee steps on the stepping pad 9, the friction between the trainee's shoes and the stepping plate 2 can be increased, thereby improving the trainee's stability and preventing him from falling;

[0023] The active base 3 and the auxiliary base 4 are fixed to the top surface of the base plate 1 by screws. An active base 3 and an auxiliary base 4 are respectively arranged on the two horizontal sides of the base plate 1. The active base 3 is fixed to the raised end of the pedal 2 by screws, and the auxiliary base 4 is fixed to the end where the pedal 2 is connected to the base plate 1 by screws. The active spring 5 is fixed to the top of the active base 3 by screws, and the auxiliary spring 6 is fixed to the top of the auxiliary base 4 by screws. The screw connection between the active spring 5 and the active base 3 and the screw connection between the auxiliary spring 6 and the auxiliary base 4 are used. The nail connection mode can quickly replace the active spring 5 and the auxiliary spring 6 when they are damaged during training, thus avoiding the common spring for bouncing being directly fixed on the base plate 1 and the pedal board 2. During the frequent disassembly process, because the base plate 1 and the pedal board 2 are made of wood, the threaded holes will become larger, which will lead to the unstable fixation of the active spring 5 and the auxiliary spring 6. One end of the top of the auxiliary spring 6 is fixed to an arc plate with screws, and then the arc plate is fixed to the bottom of the pedal board 2. The top of the active spring 5 is provided with a buffer component 7;

[0024] The buffer assembly 7 includes a connecting plate 701, which is made of alloy spring steel plate, and has a shape of a reduced version of the bottom plate 1 and the pedal 2, wherein the horizontal surface is connected to the active spring 5 by screws, and the arc surface is connected to the bottom of the pedal 2 by screws. The material of the alloy spring steel plate is utilized to ensure the elasticity of the springboard and also play a supporting role. A rectangular limiting plate 702 is welded above the horizontal surface of the connecting plate 701, and a sliding frame 703 is fixed by screws below the arc surface of the connecting plate 701. The sliding frame 703 consists of a vertical straight rod, and two support rods are connected by a fixed axis below the straight rod. The two support rods can rotate around the straight rod. A first compression spring 708 and a second compression spring 709 are respectively welded at both ends of the limiting plate 702. The first compression spring 708 is welded to the end away from the limiting plate 702 with a first slide plate 706, and the second compression spring 709 is welded to the end away from the limiting plate 702. A second slide plate 707 is welded, a first fixed seat 704 is welded in the middle of one side of the first slide plate 706 relative to the first compression spring 708, and a second fixed seat 705 is welded in the middle of one side of the second slide plate 707 relative to the second compression spring 709. A support rod at the bottom of the sliding frame 703 is fixed to the first fixed seat 704 by a fixed axis, and another support rod is fixed to the second fixed seat 705 by a fixed axis, and the two support rods of the sliding frame 703 can rotate around the first fixed seat 704 and the second fixed seat 705. At the same time, after the straight rod of the sliding frame 703 moves downward, it drives the two support rods to move to both sides, which will also drive the first slide plate 706 and the second slide plate 707 to move to both sides, thereby compressing the first compression spring 708 and the second compression spring 709. Under the action of the special material of the first compression spring 708 and the second compression spring 709 and the connecting plate 701, the active spring 5 and the auxiliary spring 6 can be assisted to bounce, thereby completing the jumping assistance work of the trainee.

[0025] Working principle: When in use, the utility model first uses the support pad 8 at the bottom of the base plate 1 to be placed in the required plane position, and then the trainee starts to run and step on the pedal 2. The friction of the pedal pad 9 can be used to stabilize it. At the moment the trainee steps on the pedal 2, the pedal 2 is pressed down. During the downward movement of the pedal 2, the active spring 5 and the auxiliary spring 6 will be compressed. At the same time, the arc plate of the connecting plate 701 in the buffer assembly 7 will also be pressed down, and then the straight rod of the sliding frame 703 will be driven to move downward, and then the two support rods will be driven to move to both sides of the limit plate 702. Because the two support rods are fixed on the first The fixing seat 704 and the second fixing seat 705 will drive the first slide plate 706 and the second slide plate 707 to move to both sides, thereby compressing the first compression spring 708 and the second compression spring 709. The first compression spring 708 and the second compression spring 709 will rebound after compression, and the active spring 5 and the auxiliary spring 6 will also rebound. During the rebound process, stepping on the pedal 2 will rebound, thereby providing a force for the trainee to complete the bouncing action. When the active spring 5 and the auxiliary spring 6 are damaged, the active spring 5 and the auxiliary spring 6 can be quickly replaced through the screws between them and the active base 3 and the auxiliary base 4.
