Description

Technical Field

[0001] This invention relates to the field of gymnastics training protective equipment technology, and in particular to a gymnastics training auxiliary protective device and its usage method. Background Technology

[0002] In daily gymnastics training, protective padding is an indispensable auxiliary protective device. It is mainly used to absorb the impact of athletes' landings, somersaults, and jumps, reducing the risk of falls and sprains. It is widely used in various gymnastics training venues. Its excellent cushioning performance effectively protects athletes' joints, bones, and muscles, playing a vital role in ensuring training safety and preventing sports injuries.

[0003] Existing gymnastics protective mats mostly adopt a one-piece, monolithic sponge-filled structure. The overall hardness and elasticity of the mat are uniform and uniform, lacking differentiated cushioning capabilities. In actual training use, the impact force generated by athletes landing tends to concentrate on the contact point. When subjected to heavy impacts such as high-altitude jumps or somersaults, local collapse is prone to occur, leading to a decrease in the flatness and elasticity uniformity of the mat surface, and consequently causing sports injuries to athletes.

Fixing members are provided on both sides of the pad, and the fixing members are used to connect multiple pads.

[0018] Preferably, the fastener includes:

[0019] Multiple connecting rods, one end of each of the multiple connecting rods being fixedly connected to both sides of the pad sleeve;

[0020] Multiple fixing blocks, one end of each fixing block being fixedly connected to the end of a multiple connecting rod away from the pad, the multiple fixing blocks and connecting rods being used to achieve a detachable stacking connection between multiple pads.

[0021] Preferably, multiple limiting blocks are fixedly installed in each of the multiple fixing slots, and one end of each of the multiple limiting blocks is slidably inserted into the outer wall of the multiple fixing frames.

[0028] The technical effects and advantages of this invention are as follows:

[0029] This invention incorporates multiple buffer springs between the sponge pad and the support frame, employing a zoned independent force principle. When an athlete lands after a high-intensity jump or somersault, the corresponding buffer springs on the sponge pad compress and deform, specifically absorbing the instantaneous impact force. The buffer springs in unloaded areas remain unchanged, preventing overall deformation due to localized impacts. This achieves an adaptive effect of strong cushioning under heavy pressure and stable support under light pressure. The multi-point independent buffer structure disperses concentrated stress in the ankles, knees, and lower back upon landing, avoiding sprains and strains caused by single-point hard impacts. Simultaneously, each buffer component rebounds independently, preventing localized compaction, rebound jamming, or permanent dents. This ensures a flat and uniformly elastic training mat surface throughout the entire process, improving training safety and equipment durability. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides, for example Figure 1-6 Shown:

[0039] Example 1: A gymnastics training auxiliary protective device includes a pad cover 1, a sponge pad 7, a support frame 8, a connecting frame 9, a fixing frame 10, a buffer spring 11, and a buffer element. The top of the sponge pad 7 is fitted against the inner wall of the top of the pad cover 1, and the bottom of the sponge pad 7 has multiple connecting grooves, providing a soft training surface. The bottom of the support frame 8 is fitted against the inner wall of the bottom of the pad cover 1, and the top of the support frame 8 has multiple fixing grooves. One end of each of the multiple connecting frames 9 is inserted into one of the multiple connecting grooves, transmitting the impact force received by the sponge pad 7 downwards. One end of each of the multiple fixing frames 10 is inserted into one of the multiple connecting grooves. Multiple fixing slots are interlocked and connected, and multiple fixing frames 10 are used to transfer the buffering force to the support frame 8; multiple buffer springs 11 are respectively disposed between multiple connecting frames 9 and multiple fixing frames 10, one end of each buffer spring 11 is fixedly connected to the end of each connecting frame 9 away from the sponge pad 7, and the other end of each buffer spring 11 is fixedly connected to the end of each fixing frame 10 away from the support frame 8. The multiple buffer springs 11 absorb energy by compressing and deforming when subjected to high-intensity impact; a buffer element is disposed at the top center of the fixing frame 10, and the buffer element is used to assist the buffer springs 11 in providing support;

[0040] Specifically, the buffer includes multiple buffer cores 12, one end of each buffer core 12 is fixedly connected to the middle of the top of multiple fixed frames 10, and the other end of each buffer core 12 away from the fixed frame 10 is fixedly connected to the bottom of multiple connecting frames 9. The multiple buffer cores 12 are used to preferentially deform under stress and provide stable support.

[0041] It should be noted that the pad 1 is a flexible outer sleeve, which houses the sponge pad 7 and the support frame 8. The top of the sponge pad 7 is fitted against the inner top wall of the pad 1, and the bottom of the sponge pad 7 has multiple connecting grooves. The bottom of the support frame 8 is fitted against the inner bottom wall of the pad 1, and the top of the support frame 8 has multiple fixing grooves. One end of each of the multiple connecting frames 9 is inserted into the corresponding connecting groove, and the other end of each of the multiple connecting frames 9 extends downward. One end of each of the multiple fixing frames 10 is inserted into the corresponding fixing groove, and the other end of each of the multiple fixing frames 10 extends upward. A buffer spring 11 is provided between the multiple connecting frames 9 and the corresponding fixing frames 10. The upper end of the buffer spring 11 is fixedly connected to the end of the connecting frame 9 away from the sponge pad 7, and the lower end of the buffer spring 11 is fixedly connected to the end of the fixing frame 10 away from the support frame 8. A buffer core 12 is fixedly installed at the middle of the top of each of the multiple fixing frames 10. The buffer core 12 is a columnar or block-shaped component made of flexible material. The end of the buffer core 12 away from the fixing frame 10 is connected to the bottom of the connecting frame 9. The fixed connection and the buffer core 12 located inside the buffer spring 11 adopt the principle of independent force distribution. When the athlete lands lightly or adjusts their posture, the flexible buffer core 12 deforms slightly to support the body, maintaining stable support and preventing collapse, thus ensuring the accuracy of training movements. When the athlete lands from a high jump or somersault, generating a high-intensity impact, the buffer spring 11 and buffer core 12 in the corresponding force-bearing area compress and deform synchronously to absorb the instantaneous impact force. The buffer spring 11 and buffer core 12 in the unforced area remain in their original shape and will not deform as a whole with local impact, achieving an adaptive effect of heavy pressure large buffer and light pressure stable support. The multi-point independent buffer structure can disperse the local concentrated stress on the ankle, knee, and waist when landing, avoiding sprains and strains caused by single-point hard impact. At the same time, each set of buffer springs 11 and buffer core 12 rebounds independently, preventing local compaction, rebound jamming, and permanent dents. This ensures that the training mat surface is flat and elastic throughout the entire process, improving training safety and equipment durability.

[0042] The bottom of the support frame 8 is provided with multiple adjustment slots, which are connected to multiple fixing slots respectively. Adjustment components are provided in the multiple adjustment slots. The adjustment components are used to adjust the position of the fixing frame 10 in the vertical direction and change the degree of contact between the connecting frame 9 and the sponge pad 7 and the pre-compression amount of the buffer spring 11.

[0043] Specifically, the adjusting component includes multiple adjusting bolts 13, one end of which is inserted into the bottom of the support frame 8, and the threaded ends of the multiple adjusting bolts 13 are respectively inserted into the bottom threads of multiple fixing frames 10.

[0044] It should be noted that the support frame 8 has multiple adjustment slots at its bottom. The adjustment slots are vertical through holes, and each adjustment slot is connected to the bottom of the corresponding fixed slot. One end of the adjustment bolt 13 passes through the adjustment slot from the bottom of the support frame 8. The threaded end of the adjustment bolt 13 extends upward and is threadedly connected to the bottom of the fixed frame 10. By rotating the adjustment bolt 13, the position of the fixed frame 10 in the vertical direction can be changed, thereby adjusting the fit between the connecting frame 9 and the sponge pad 7 and the pre-compression of the buffer spring 11. When it is found that the connecting frame 9 cannot fit tightly with the connecting slot at the bottom of the sponge pad 7 during use, the height of the fixed frame 10 can be adjusted by rotating the adjustment bolt 13, so that the connecting frame 9 moves upward and fits back into the connecting slot, eliminating the gap. At the same time, adjusting the height of the fixed frame 10 will also change the pre-compression of the buffer spring 11, thereby adjusting the initial elasticity of the buffer spring 11 to adapt to the needs of different weights or different training intensities.

[0045] A sponge bracket 14 is fixedly installed at the bottom of the sponge pad 7. The bottom of the sponge bracket 14 is attached to the top of the support frame 8. The sponge bracket 14 is used to provide uniform support for the sponge pad 7 and prevent the buffer springs 11 from getting tangled or interfering with each other.

[0046] Multiple limiting blocks 15 are fixedly installed in multiple fixed slots. The ends of the multiple limiting blocks 15 that are close to each other are slidably inserted and connected to the outer walls of multiple fixed frames 10. The multiple limiting blocks 15 are used to restrict the circumferential rotation of the fixed frames 10.

[0047] It should be noted that the bottom of the sponge pad 7 is fixedly connected to the top of the sponge bracket 14. The sponge bracket 14 has a mesh structure, and its bottom is fixedly connected to the top of the support frame 8, placing the sponge bracket 14 between the sponge pad 7 and the support frame 8. The top of the support frame 8 has multiple fixing grooves, and multiple limiting blocks 15 are fixedly installed in each of the fixing grooves. The limiting blocks 15 are protruding block structures distributed circumferentially along the inner wall of the fixing groove. The ends of the limiting blocks 15 that are close to each other are slidably inserted into the outer wall of the fixing frame 10, so that the fixing frame 10 can only move axially within the fixing groove and cannot rotate around its own axis. The sponge bracket 14 fills the sponge pad 7 and... The gaps between the support frames 8 provide uniform support for the sponge pad 7, preventing local collapse of the sponge pad 7. At the same time, the sponge bracket 14 separates the multiple buffer springs 11 into their own independent spaces, avoiding entanglement or interference between the buffer springs 11, ensuring that each set of buffer springs 11 and the buffer core 12 work independently. The limiting block 15, through sliding cooperation with the outer wall of the fixed frame 10, constrains the circumferential freedom of the fixed frame 10, effectively preventing the fixed frame 10 from rotating under the action of the adjusting bolt 13 or the buffer springs 11, ensuring that the fixed frame 10 always maintains the correct alignment with the connecting frame 9, ensuring that the compression direction of the buffer springs 11 is always vertical, and avoiding off-center loading.

[0048] Multiple anti-slip blocks 6 are fixedly installed on the top of the pad 1. The multiple anti-slip blocks 6 are used to increase friction. A pull strap 5 is fixedly installed on the front end of the pad 1. The pull strap 5 is used to easily pull the pad 1 to move or adjust its position.

[0049] Both sides of the pad 1 are fixedly installed with connecting straps 2. Multiple connecting straps 2 are provided with multiple fixing grooves at the ends away from the pad 1. Fixing members are provided on both sides of the pad 1. The fixing members are used to connect multiple pads 1.

[0050] The fasteners include connecting rods 3 and fixing blocks 4; one end of each connecting rod 3 is fixedly connected to both sides of the pad 1; one end of each fixing block 4 is fixedly connected to the end of each connecting rod 3 away from the pad 1; the fixing blocks 4 and connecting rods 3 are used to realize the detachable stacking connection between the multiple pads 1.

[0051] It should be noted that multiple anti-slip blocks 6 are fixedly installed on the top of the pad 1. The anti-slip blocks 6 are raised particles used to increase friction. A pull strap 5 is fixedly installed on the front end of the pad 1 for pulling the pad 1. A connecting strap 2 is fixedly installed on each side of the pad 1. The connecting strap 2 is a flexible strip. Multiple fixing grooves are opened at the end of the connecting strap 2 away from the pad 1. The fixing grooves are through holes. Multiple connecting rods 3 are also fixedly installed on both sides of the pad 1. The ends of the multiple connecting rods 3 away from the pad 1 extend outward and are fixedly connected to fixing blocks 4. The fixing blocks 4 are block-shaped components. The shape of the fixing blocks 4 is larger than the fixing grooves. The pull strap 5 facilitates pulling. The entire auxiliary protection device can be moved. The anti-slip block 6 is used to prevent the pad 1 from sliding during use, thus improving safety. When multiple pads 1 need to be stacked, the fixing grooves on the connecting strips 2 on both sides of the upper pad 1 are aligned with the connecting rods 3 and fixing blocks 4 on both sides of the lower pad 1 and snapped together. The connecting strips 2 are fixed by the fixing blocks 4, thereby connecting multiple pads 1 to each other. Different numbers of pads 1 can be spliced ​​together to meet different training height requirements. When not in use, the fixing grooves on the connecting strips 2 themselves can be snapped together with the connecting rods 3 and fixing blocks 4 on the pad 1 on the same side to gather and fix the connecting strips 2 for easy storage.

[0052] Example 2: A method of using a gymnastics training auxiliary protection device, comprising the above-mentioned gymnastics training auxiliary protection device, the method of use includes the following steps:

[0053] First, put the buffer spring 11 on the outside of the buffer core 12, and then connect the connecting frame 9 and the fixed frame 10 through the buffer spring 11 and the buffer core 12. The two ends of the buffer core 12 are fixedly connected to the bottom of the connecting frame 9 and the top of the fixed frame 10 respectively. Insert the lower end of the fixed frame 10 into the fixing groove at the top of the support frame 8 so that the outer wall of the fixed frame 10 slides with the limiting block 15 to prevent rotation. If necessary, adjust the height of the fixed frame 10 by rotating the adjusting bolt 13 at the bottom of the support frame 8 so that the upper end of the connecting frame 9 is aligned with the connecting groove at the bottom of the sponge pad 7 to be installed later, and adjust the pre-compression amount of the buffer spring 11.

[0054] The second step is to place the sponge bracket 14 on top of the support frame 8, align the through holes on the sponge bracket 14 with each connecting frame 9, and then place the sponge pad 7 on the sponge bracket 14, so that the connecting groove at the bottom of the sponge pad 7 is inserted and connected to the top of the corresponding connecting frame 9, ensuring that the connecting frame 9 is completely embedded in the connecting groove, and the sponge bracket 14 provides uniform support for the sponge pad 7.

[0055] Third, place the assembled sponge pad 7 and support frame 8 into the pad sleeve 1, ensuring that the top inner wall of the pad sleeve 1 is flush with the top of the sponge pad 7 and the bottom inner wall of the pad sleeve 1 is flush with the bottom of the support frame 8. After adjusting the position, close the opening of the pad sleeve 1, so that the pad sleeve 1 wraps and secures the sponge pad 7 and support frame 8.

[0056] Fourth, when the training height needs to be increased, stack multiple packaged gymnastics training auxiliary protection devices one on top of the other. Align and snap the fixing grooves on the connecting straps 2 on both sides of the upper pad 1 with the connecting rods 3 and fixing blocks 4 on both sides of the lower pad 1. Lock the connecting straps 2 with the fixing blocks 4 to fix the multiple pads 1 together. Repeat this operation until the desired height is reached. When not in use, the fixing grooves on the connecting straps 2 themselves can be snapped with the connecting rods 3 and fixing blocks 4 on the pad 1 on the same side to fold and fix the connecting straps 2 for easy storage.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
