Description

Technical Field

[0001] This utility model relates to the field of sports training equipment, and in particular to a football goalkeeper reaction trainer. Background Technology

[0002] As one of the world's most popular sports, football places a crucial role on the goalkeeper. A goalkeeper's reaction speed, agility, and ball handling ability directly impact a team's defensive effectiveness and the outcome of the match. Therefore, effective training for goalkeeper reaction abilities is essential, leading to the development of various goalkeeper reaction training devices.

[0003] While existing football goalkeeper reaction trainers can help goalkeepers improve their reaction skills to some extent, several problems remain. Especially during high-intensity, full-load training, goalkeepers experience a gradual buildup of fatigue, particularly in the arms. At this point, when using the trainer to catch and bounce the ball, insufficient hand strength makes it difficult to maintain stable control. This can cause the metal frame of the trainer to easily malfunction upon impact with the ball, potentially striking the goalkeeper's face or head, posing a serious threat to their safety. This potential safety risk not only affects the continuity and motivation of goalkeeper training but also limits further improvements in training intensity and effectiveness. Furthermore, frequent such accidents can create psychological stress for goalkeepers, negatively impacting their technical performance. Utility Model Content

[0004] The main purpose of this invention is to propose a football goalkeeper reaction trainer, which aims to solve the problem that while existing football goalkeeper reaction trainers can help improve reaction skills, when goalkeepers are under high-intensity, full-load training and their arms become exhausted, they are unable to stabilize the trainer due to insufficient hand strength. The U-shaped trainer is also prone to losing control and hitting the goalkeeper's face or head under the impact of the football, which poses a safety risk, affects the continuity, motivation, and intensity of training, and may also cause psychological pressure that affects technical performance.

[0005] To address the aforementioned problems, this utility model proposes a football goalkeeper reaction trainer, comprising a U-shaped metal frame and a U-shaped mesh frame disposed on the inner wall of the U-shaped metal frame. The U-shaped mesh frame is fixedly connected to the U-shaped metal frame by multiple embedded screws. A football rebound net is disposed inside the U-shaped mesh frame. The football rebound net is woven in a grid pattern with equal spacing by multiple high-strength elastic ropes inside the U-shaped mesh frame. The football rebound net is taut when not under stress inside the U-shaped mesh frame. Inflatable buffer protection devices are provided at both the upper and lower ends of the U-shaped metal frame.

[0006] In one embodiment, the inflatable buffer protection device at the top of the metal frame of the U-shaped trainer includes an adhesive fixing piece, an L-shaped hollow rubber airbag, and an inflation / deflation rubber nozzle. The adhesive fixing piece is attached to the top and the outer wall of the top rear end of the metal frame of the U-shaped trainer. The L-shaped hollow rubber airbag is attached to the top and the outer wall of the rear end of the adhesive fixing piece. An inflation / deflation rubber nozzle is provided on the right side of the center of the top of the L-shaped hollow rubber airbag, and the inflation / deflation rubber nozzle communicates with the interior of the L-shaped hollow rubber airbag.

[0007] In one embodiment, the inflatable buffer protection device further includes a vent hole and a conical self-sealing plug. The conical self-sealing plug is disposed inside the center of the inflation / deflation rubber nozzle, and the conical self-sealing plug is fixedly connected to the inner wall of the inflation / deflation rubber nozzle by an adhesive and a sealant. The vent hole is disposed inside the center of the conical self-sealing plug.

[0008] In one embodiment, the conical self-sealing plug is arranged in a conical downward position inside the inflation / deflation rubber nozzle. The conical self-sealing plug can automatically shrink the vent hole at its center through its own material properties and elasticity, so that the vent hole is in a contracted and closed state. The injection head of the syringe can be forcefully inserted into the vent hole, and the L-shaped hollow rubber air bag can be inflated or deflated through the syringe. After the injection head of the syringe is withdrawn, the vent hole automatically contracts and closes.

[0009] In one embodiment, the inflatable buffer protection device further includes a sealing patch and a rubber sealing plug. The top of the inflation / deflation rubber nozzle is provided with a sealing patch, and the bottom of the sealing patch is provided with a rubber sealing plug, which is inserted into the top opening of the inflation / deflation rubber nozzle.

[0010] In one embodiment, the bottom edge of the rubber sealing plug is rounded to facilitate accurate insertion into the top opening of the inflation / deflation rubber nozzle. The rubber sealing plug and the inflation / deflation rubber nozzle are interference-fitted, and the rubber sealing plug can further prevent air inside the L-shaped hollow rubber airbag from leaking out through the inflation / deflation rubber nozzle.

[0011] In one embodiment, the corners of the metal frame of the loop-shaped trainer are all treated with large arc surfaces, and the inner and outer edges of the loop at both ends of the metal frame of the loop-shaped trainer are treated with small arc surfaces. Both the metal frame and the loop-shaped mesh frame of the loop-shaped trainer are made of aluminum alloy, and the outer walls of both the metal frame and the loop-shaped mesh frame are coated with paint.

[0012] In one embodiment, the metal frame of the U-shaped trainer is provided with U-shaped metal training handles at both ends of the rear end and on the outer wall of the rear end. The top and bottom corners of the rear end of the two U-shaped metal training handles are treated with arc surface passivation, and the two U-shaped metal training handles are arranged symmetrically on the left and right.

[0013] In one embodiment, handle fixing blocks are welded to both ends of the U-shaped opening of the U-shaped metal training handle. The handle fixing blocks are attached to the outer rear wall of the metal frame of the U-shaped trainer, and the handle fixing blocks are fixedly connected to the metal frame of the U-shaped trainer by handle fixing screws.

[0014] In one embodiment, the handle fixing screw is an internal hexagon screw, and the rear half of the handle fixing block is also provided with an anti-disengagement groove, and the internal hexagon screw head of the handle fixing screw is inserted into the anti-disengagement groove.

[0015] Beneficial Effects: The technical solution of this utility model adds a novel inflatable cushioning protection device to the top and bottom of the metal frame of the loop-shaped training device. When a soccer goalkeeper holds two U-shaped metal training handles with both hands to catch a shot of the soccer ball and bounce it off the net for reaction training, if the goalkeeper's arms become weak due to full-load training, the metal frame of the loop-shaped training device may strike the goalkeeper's face or head during the catching and bouncing of the ball. This novel inflatable cushioning protection device addresses this by modifying the L-shaped hollow rubber airbag. The internal inflation volume of the L-shaped hollow rubber bladder can be flexibly adjusted to accommodate various training intensities. When soccer goalkeepers are engaged in full-load reaction training, their arms experience greater fatigue, making it easier and more frequent for the metal frame of the training device to impact their face or forehead. In this situation, a fully inflated L-shaped hollow rubber bladder can effectively cushion the impact of the metal frame, reducing injury to the goalkeeper's face and head. During low-intensity training, the inflation volume can be reduced appropriately, without affecting the training experience, while also reducing the device's weight and improving training flexibility. This device greatly improves training safety, ensuring goalkeepers can better focus on their training. Attached Figure Description

[0028] This utility model provides, for example Figure 1-5The illustrated football goalkeeper reaction trainer includes a U-shaped metal frame 1 and a U-shaped mesh frame 5 disposed on the inner wall of the U-shaped metal frame 1. The U-shaped mesh frame 5 is fixedly connected to the metal frame 1 by multiple embedded screws. A football rebound net 6 is disposed inside the U-shaped mesh frame 5. The football rebound net 6 is composed of multiple high-strength elastic ropes woven in a crisscross pattern at equal intervals inside the U-shaped mesh frame 5. The football rebound net 6 is taut when not under stress inside the U-shaped mesh frame 5. The football rebound net 6 disposed inside the U-shaped mesh frame 5 is the core of the trainer. The training component, the soccer rebound net 6, is made of multiple high-strength elastic ropes woven in a crisscross pattern at equal intervals inside the loop-shaped net frame 5. When not under stress, it is taut. When a soccer ball is shot at the rebound net at different speeds and angles, due to the elasticity of the ropes and the weaving structure, the ball will bounce back according to corresponding physical laws. This rebound simulates the situation in an actual match where a soccer ball is shot at the goalkeeper from different directions and with different forces. The goalkeeper holds the U-shaped metal training handles 3 located on the outer walls of the rear ends of the metal frame 1 of the loop-shaped trainer, and changes position by moving the trainer. To train the ability to anticipate and react quickly to footballs bouncing in different directions, the metal frame 1 of the loop-shaped trainer features large arc-shaped corners and small arc-shaped inner and outer edges at both ends. Both the metal frame 1 and the loop-shaped mesh frame 5 are made of aluminum alloy and are painted. The trainer mainly consists of the metal frame 1 and the loop-shaped mesh frame 5, which are securely connected to the ball's trajectory using multiple embedded screws. The inner wall of the metal frame 1 of the loop-shaped trainer is designed to ensure the stability of the overall structure and withstand the impact of the football. Both the metal frame 1 and the mesh frame 5 are made of aluminum alloy, which combines lightweight and high strength. This allows goalkeepers to move the trainer flexibly during training while ensuring it is not easily damaged by frequent football impacts over a long period. In addition, the outer walls of the metal frame and mesh frame are painted, which not only enhances the appearance but also prevents the metal from rusting and corroding, extending the service life of the trainer.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, U-shaped metal training handles 3 are provided at both ends of the metal frame 1 of the loop-shaped trainer and on the outer wall of the rear end. The top and bottom corners of the rear end of the two U-shaped metal training handles 3 are rounded and blunted. The two U-shaped metal training handles 3 are symmetrically arranged. Handle fixing blocks 4 are welded to both ends of the U-shaped opening of the U-shaped metal training handle 3. The handle fixing blocks 4 are attached to the outer wall of the rear end of the metal frame 1 of the loop-shaped trainer and are fixedly connected to the metal frame 1 of the loop-shaped trainer by handle fixing screws 2. The handle fixing screws 2 are internal hexagon screws. The rear half of the handle fixing block 4 is also provided with an anti-disengagement groove, and the internal hexagon screw head of the handle fixing screw 2 is inserted into the anti-disengagement groove. The U-shaped metal training handles 3 provide a good grip point for the goalkeeper, making it convenient for him to... During training, the trainer can be moved quickly to deal with footballs from different directions. The top and bottom corners of the two U-shaped metal training handles 3 are rounded and blunted. This design can effectively prevent sharp edges from causing accidental injury to the goalkeeper during training. The handle fixing blocks 4 welded to both ends of the U-shaped opening of the handle are fixedly connected to the metal frame 1 of the U-shaped trainer by the handle fixing screws 2. The handle fixing screws 2 are hexagonal screws, and the rear half of the handle fixing block 4 is provided with an anti-disengagement groove. The hexagonal screw head is inserted into the anti-disengagement groove. This connection method not only ensures the stability of the connection between the handle and the metal frame of the trainer and prevents the handle from loosening and falling off during training, but also further enhances the reliability of the connection through the anti-disengagement groove design, ensuring the safety and stability of the training process.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, the metal frame 1 of the spiral-shaped trainer is equipped with inflatable cushioning protection devices 7 at both the top and bottom. The inflatable cushioning protection device 7 at the top of the metal frame 1 includes an adhesive fixing piece 8, an L-shaped hollow rubber airbag 9, and an inflation / deflation rubber nozzle 10. The adhesive fixing piece 8 is attached to the top and the outer wall of the top rear end of the metal frame 1. The L-shaped hollow rubber airbag 9 is attached to the top and the outer wall of the rear end of the adhesive fixing piece 8. An inflation / deflation rubber nozzle 10 is located on the right side of the center of the top of the L-shaped hollow rubber airbag 9. The inflation / deflation rubber nozzle 10 communicates with the interior of the L-shaped hollow rubber airbag 9. The inflatable cushioning protection device 7 is installed on the metal frame 1 of the spiral-shaped trainer. Taking the device at the top of the metal frame 1 of the loop-shaped trainer as an example, the connection with the metal frame is first achieved by attaching the fixing plate 8. The fixing plate 8 is attached to the top of the metal frame 1 of the loop-shaped trainer and the outer wall of the top rear end, providing a stable attachment base for subsequent components. The L-shaped hollow rubber airbag 9 is attached to the top of the fixing plate 8 and the outer wall of the rear end. This layout allows the airbag to be reasonably distributed on the edge of the metal frame, providing buffer protection in the position where the goalkeeper may be hit. The inflation / deflation rubber nozzle 10 is located on the right side of the center of the top of the L-shaped hollow rubber airbag 9 and is connected to the inside of the airbag. It is the key channel for realizing the inflation and deflation of the airbag.

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the inflatable buffer protection device 7 also includes a vent hole 12 and a conical self-sealing plug 14. A conical self-sealing plug 14 is disposed inside the center of the inflation / deflation rubber nozzle 10, and the conical self-sealing plug 14 is fixedly connected to the inner wall of the inflation / deflation rubber nozzle 10 by adhesive and sealant. A vent hole 12 is disposed inside the center of the conical self-sealing plug 14, which is arranged in a conical, downward-facing manner inside the inflation / deflation rubber nozzle 10. The conical self-sealing plug 14 can automatically contract the vent hole 12 inside its center through its own material properties and elasticity, keeping the vent hole 12 in a contracted and closed state. An injection head of a syringe can be forcefully inserted into the vent hole 12, and the L-shaped hollow rubber airbag 9 can be inflated or deflated through the syringe. After the injection head of the syringe is withdrawn, the vent hole 12 automatically contracts and closes. The conical self-sealing plug 14 and... The vent 12 design enables convenient and reliable inflation and deflation. The conical self-sealing plug 14 is located inside the center of the inflation / deflation rubber nozzle 10 and is firmly fixed to the inner wall of the inflation / deflation rubber nozzle 10 by adhesive and sealant. The vent 12 is set inside the center of the plug and is installed in a conical downward position. Under normal conditions, the conical self-sealing plug 14 automatically contracts the vent 12 based on its own material properties and elasticity, keeping it in a closed state to prevent gas leakage from the airbag. When it is necessary to inflate or deflate the L-shaped hollow rubber airbag 9, the syringe head can be inserted into the vent 12 by forceful insertion. At this time, the syringe can smoothly inject or extract gas into the airbag. After the syringe head is withdrawn, the vent 12 will automatically contract and close under the elasticity of the conical self-sealing plug 14 to ensure that the gas in the airbag remains stable.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, the inflatable buffer protection device 7 also includes a sealing patch 11 and a rubber sealing plug 13. The top of the inflation / deflation rubber nozzle 10 is also provided with a sealing patch 11, and the bottom of the sealing patch 11 is provided with a rubber sealing plug 13. The rubber sealing plug 13 is inserted into the top opening of the inflation / deflation rubber nozzle 10. The bottom edge of the rubber sealing plug 13 is rounded to facilitate accurate insertion into the top opening of the inflation / deflation rubber nozzle 10. The rubber sealing plug 13 and the inflation / deflation rubber nozzle 10 are press-fitted. The rubber sealing plug 13 further prevents air inside the L-shaped hollow rubber airbag 9 from leaking out through the inflation / deflation rubber nozzle 10. To further prevent air leakage from inside the L-shaped hollow rubber airbag 9, the device... A sealing patch 11 and a rubber sealing plug 13 are also provided. The sealing patch 11 is located at the top of the inflation / deflation rubber nozzle 10, and the rubber sealing plug 13 at its bottom end is inserted into the top opening of the inflation / deflation rubber nozzle 10. The bottom edge of the rubber sealing plug 13 is rounded, which facilitates accurate insertion into the top opening of the inflation / deflation rubber nozzle 10. The rubber sealing plug 13 and the inflation / deflation rubber nozzle 10 are interference-fitted and fit tightly. This interference-fit connection can effectively prevent the air inside the L-shaped hollow rubber airbag 9 from leaking out through the inflation / deflation rubber nozzle 10, ensuring stable air pressure inside the airbag, thereby ensuring that the buffer protection device can play a continuous and effective role throughout the training process.
