Description

Technical Field

[0001] The invention belongs to the technical field of football training equipment, in particular to a football shooting training device with a football sending back function. Background Art

[0002] In soccer training, shooting practice is a key step in improving players' skills, and efficient training equipment plays a crucial role in achieving effective training. Currently, various shooting practice devices are available on the market. Devices with ball-returning functions significantly improve training efficiency, reducing the time players spend retrieving the ball and enabling more intensive shooting practice.

[0003] For example, patent publication number CN221998819U discloses a soccer shooting practice device with a soccer ball return function, which includes a ball frame and a device housing. By providing a return assembly and a limit assembly, the soccer ball shot into the ball frame can be collected and returned by the return assembly.

[0004] In most football training scenarios, the field is often not completely clean, and the football will inevitably be contaminated with impurities such as mud and sand during use. After the shooting practice is completed, the football with mud and sand is returned to the launch tube for the next launch. In order to improve the stability of the football during launch, the inner diameter of the launch channel is usually adapted to the outer diameter of the football.

[0005] When the football is driven by air pressure to move in the launch tube, the mud and sand frequently rub and scrape against the surface of the football. If this continues for a long time, the surface of the football will easily be scratched, damaged, and peeled. Once the football is scratched, it will not only shorten its service life but also increase training costs.

[0006] To this end, the present invention provides a football shooting practice device with a football sending back function. Summary of the Invention

The present invention is provided with a storage cylinder, a control plug, a connecting shaft and an extrusion plate. The extrusion plate reciprocates to squeeze the coating layer that absorbs the cleaning liquid, so that the coating layer can discharge the sewage absorbed inside, further keeping the coating layer clean. A guide ring and a guide ball are also provided. When the connecting shaft rises and falls and slides along the axis, the guide ball slides along the inner wall of the spiral groove, thereby controlling the rotation of the connecting shaft and driving the extrusion plate to rotate. In the process of the extrusion plate extruding the coating layer, the coating layer is rubbed, further improving the cleaning quality of the coating layer, thereby maintaining the cleaning quality of the coating layer on the football, reducing the wear of the football when it occurs, and increasing the service life of the football.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 10 As shown, a soccer shooting practice device with a soccer ball returning function according to an embodiment of the present invention comprises a supporting portion, a transporting mechanism, a wetting mechanism, a guiding mechanism and a launching portion; The support part includes a ball net frame 1 and a mounting frame 2. The ball net frame 1 can be detachably mounted on the side wall of the mounting frame 2. The ball net frame 1 is used to support a nylon net (not shown in the figure) and to provide a target point when practicing soccer shooting. The ball net frame 1 is connected to the mounting frame 2 by bolts for easy assembly and separation.

[0023] The transfer mechanism includes a carrying plate 8 and a curved plate 13. The carrying plate 8 is rotatably arranged above the mounting frame 2. The curved plate 13 is used to clamp the football and is arranged in the carrying plate 8. The curved plate 13 is made of elastic material and has a "U"-shaped structure. A groove for storing the curved plate 13 is opened on the carrying plate 8, and multiple grooves are evenly arranged along the axis of the carrying plate 8.

[0024] After the shot, the staff pushes the football caught by the nylon net into the arc plate 13, and the arc plate 13 clamps the football. At this time, the supporting plate 8 rotates, driving the football to rotate synchronously along the axis of the supporting plate 8.

[0025] It should be noted that in order to facilitate the rotation of the football along its own center, a steel ball is provided in the arc plate 13 for contacting the football and reducing the friction between the arc plate 13 and the surface of the football when clamping the football.

[0026] The wetting mechanism includes a coating layer 15 and an adapter plate 11. The adapter plate 11 is arranged directly above the supporting plate 8, and a cavity is provided inside for storing cleaning liquid (in this embodiment, the cleaning liquid is clean water as an example). The axis of the adapter plate 11 coincides with the axis of the supporting plate 8. A conduit connecting to an external cleaning liquid storage chamber is provided on the outer wall of the adapter plate 11, which is used to replenish the cleaning liquid when the cleaning liquid level inside the adapter plate 11 is too low.

[0027] The coating layer 15 is fixedly mounted on the bottom of the adapter plate 11 and is made of an elastic water-absorbing material. In this embodiment, the coating layer 15 is made of a sponge to absorb the cleaning liquid in the adapter plate 11, thereby making the coating layer 15 itself moist. When the football is pushed into the curved plate 13, the bottom of the coating layer 15 fits against the outer wall of the football.

[0028] During the rotation of the supporting plate 8, the football inside the arc plate 13 revolves synchronously along the axis of the supporting plate 8. At the same time, affected by the friction between the coating layer 15 and the surface of the football, the football revolves around its own center, thereby wiping the dirt (such as mud and sand) on the surface of the football through the coating layer 15, thereby cleaning the football.

[0029] The launching part includes a guide tube 6 and a connecting nozzle 7 for connecting to an external high-pressure chamber. The connecting nozzle 7 is fixedly installed in the inner cavity of the guide tube 6. The external high pressure is transmitted to the inner cavity of the guide tube 6 through the connecting nozzle 7. The cleaned football is placed in the interior of the guide tube 6, and the football is launched by high pressure to realize the return of the football.

[0030] The guide mechanism is used to transport the football after the coating layer 15 is wiped to the inside of the guide tube 6. After the football is cleaned, it is launched, which can effectively reduce the risk of scratching the surface of the football and extend the service life of the football. At the same time, it prevents scratches on the inside of the guide tube 6, keeps the inner wall of the guide tube 6 smooth, and reduces friction with the guide tube 6 when the football is launched, thereby reducing damage to the football.

[0031] At the same time, since the football is launched by air pressure, water stains remain on the surface of the football after the coating layer 15 is wiped. After the surface of the football is soaked, the moisture can form a water film between the football and the inner wall of the guide tube 6, effectively reducing the friction between the two, thereby improving the launch speed and efficiency.

[0032] The guide mechanism includes a pneumatic telescopic rod 22 , a connecting tube 16 and a transfer tube 9 .

[0033] The mounting end of the pneumatic telescopic rod 22 is fixedly connected to the inner wall of the carrying plate 8, and the movable end of the pneumatic telescopic rod 22 passes through the arc plate 13. A rubber pad is provided at the movable end of the pneumatic telescopic rod 22, and the football wiped clean in the arc plate 13 is pushed out through the pneumatic telescopic rod 22.

[0034] One end of the connecting tube 16 is communicated with the inner cavity of the transfer tube 9 , and the other end of the connecting tube 16 is connected to the air pressure interface of the pneumatic telescopic rod 22 , so as to provide an air source for the movable end of the pneumatic telescopic rod 22 .

[0035] The transfer tube 9 is fixedly mounted at the center of the axial end of the carrier plate 8 , and a sealed bearing is provided inside the transfer tube 9 so that when the carrier plate 8 rotates, the transfer tube 9 is connected to the external air source, thereby providing power for the pneumatic telescopic rod 22 .

[0036] As a preferred embodiment of the present invention, a bearing plate 5 is fixedly mounted on the upper end surface of the mounting frame 2 , a support ring 28 is rotatably mounted on the outer wall of the bearing plate 5 , and the bearing plate 5 provides a mounting and supporting position for the support ring 28 .

[0037] The outer wall of the support ring 28 is fixedly connected to the bottom surface of the carrying plate 8 , and the support ring 28 is used to realize the rotational connection between the carrying plate 5 and the carrying plate 8 .

[0038] The upper end surface of the supporting plate 5 is fixedly mounted with a closed ring 4, and the bottom surface of the adapter plate 11 is fixedly connected to the upper end of the closed ring 4, so that when the supporting plate 8 rotates, the football is subjected to centrifugal force and falls off.

[0039] The bottom surface of the adapter plate 11 is provided with a drain port, in which a capillary layer 19 is fixedly installed. The capillary layer 19 is made of common cotton wool and is used to reduce the discharge speed of the cleaning liquid while keeping the coating layer 15 in a moist state. In order to keep the coating layer 15 absorbing the cleaning liquid as evenly as possible, multiple drainage ports are provided, and multiple drainage ports are evenly arranged in a ring shape along the axis of the adapter plate 11. By increasing the water absorption position of the coating layer 15, the coating layer 15 can be kept as evenly absorbing the cleaning liquid as possible.

[0040] A scraper plate 14 is fixedly installed on the upper end surface of the carrier plate 8. The scraper plate 14 is made of elastic material and is set at an angle. During the rotation of the carrier plate 8, the scraper plate 14 rotates synchronously, thereby squeezing and scraping the surface of the coating layer 15, thereby achieving the cleaning of the coating layer 15 itself, maintaining the water absorption efficiency of the coating layer 15, and improving the wiping and cleaning quality of the coating layer 15.

[0041] A V-shaped groove is provided on the upper end surface of the supporting plate 5, and a guide ball 17 is installed thereon for rolling. The guide ball 17 is provided to support the football on the supporting plate 5 and reduce the friction of the football's rotation. A sewage outlet 18 is provided at the bottom of the supporting plate 5 to facilitate the discharge of sewage generated by wiping and cleaning.

[0042] As a preferred embodiment of the present invention, the outer wall of the guide tube 6 is fixedly connected to the outer wall of the closed ring 4, and the inner cavities are interconnected, so that the football pushed out from the arc plate 13 can enter the inner cavity of the guide tube 6.

[0043] A feeding plug 37 is slidably provided in the inner cavity of the guide cylinder 6 , and the outer wall of the feeding plug 37 is in sealing contact with the inner cavity of the guide cylinder 6 .

The movable end of the control cylinder 10 extends to the inner cavity of the guide cylinder 6 and is fixedly connected to the outer wall of the feed plug 37. After the football enters the inner cavity of the guide cylinder 6, the feed plug 37 is driven to slide by the control cylinder 10 until the feed plug 37 passes the connection position between the guide cylinder 6 and the closed ring 4 (at this time, the outer wall of the feed plug 37 is flush with the connecting nozzle 7), and then high-pressure gas is introduced into the inner cavity of the guide cylinder 6 through the connecting nozzle 7, and the football is discharged by air pressure. After the football is discharged, the control cylinder 10 controls the feed plug 37 to reset.

[0045] As a preferred embodiment of the present invention, a storage cylinder 21 is fixedly installed on the inner wall of the carrier plate 8, and a control plug 29 is elastically installed in the inner cavity of the storage cylinder 21. The radial outer wall of the control plug 29 is sealed with the inner wall of the storage cylinder 21, and the control plug 29 is driven to slide by adjusting the air pressure in the inner cavity of the storage cylinder 21.

[0046] A connecting shaft 32 is rotatably mounted on the upper end surface of the control plug 29, and an extrusion plate 20 is fixedly mounted on the other end of the connecting shaft 32. During the sliding of the control plug 29, the extrusion plate 20 is driven to slide by the connecting shaft 32, and the coating layer 15 that absorbs the cleaning liquid is reciprocated by the extrusion plate 20, so that the coating layer 15 can discharge the sewage absorbed inside, thereby further keeping the coating layer 15 itself clean.

[0047] A guide ring 31 is fixedly mounted on the inner wall of the storage tube 21 , and the connecting shaft 32 passes through the guide ring 31 , and the outer wall and the inner wall of the guide ring 31 are slidably fitted together. The provision of the guide ring 31 can effectively improve the sliding stability of the connecting shaft 32 .

[0048] A spiral groove 35 is provided on the radial outer wall of the connecting shaft 32, and a plurality of spiral grooves 35 are evenly arranged along the axis of the connecting shaft 32. A guide ball 24 that slides with the spiral groove 35 is fixed to the inner wall of the guide ring 31. When the connecting shaft 32 rises and falls and slides along the axis, the guide ball 24 slides along the inner wall of the spiral groove 35, thereby controlling the rotation of the connecting shaft 32 and driving the extrusion plate 20 to rotate. In the process of the extrusion plate 20 extruding the coating layer 15, the coating layer 15 is rubbed, further improving the cleaning quality of the coating layer 15, thereby maintaining the cleaning quality of the coating layer 15 on the football, reducing the wear of the football when it occurs, and increasing the service life of the football.

[0049] A control cylinder 30 is fixedly mounted on the inner wall of the support ring 28 , and a movable plug 33 is slidably mounted on the inner wall of the control cylinder 30 . The movable plug 33 is made of rubber, and its outer wall is sealed and fitted with the inner wall of the control cylinder 30 .

[0050] The inner wall of the control cylinder 30 is fixedly mounted with a guide frame 23 , and the outer wall of the guide frame 23 is connected to the side wall of the movable plug 33 via an elastic member. The elastic member is a spring, one end of which is connected to the movable plug 33 and the other end is connected to the guide frame 23 .

[0051] A connecting rod 34 is slidably installed on the inner wall of the guide frame 23, and the other end of the connecting rod 34 is fixedly connected to the outer wall of the movable plug 33. The movable plug 33 is driven to slide by the reciprocating sliding connecting rod 34, and the inner cavity of the control cylinder 30 is connected with the inner cavity of the storage cylinder 21 through the conduit, thereby driving the control plug 29 to slide back and forth, so that the extrusion plate 20 reciprocates to extrude the coating layer 15 while kneading the coating layer 15.

[0052] A control box 3 is fixedly mounted on the upper end surface of the mounting frame 2 , and a worm gear and a worm that mesh with each other are arranged inside the control box 3 .

The one-way transmission member is a one-way clutch. When the transmission disc 36 rotates forward, it drives the transmission shaft 26 and the carrying disc 8 to rotate, thereby transporting the football and cleaning the football at the same time.

[0054] A transmission ring 25 is installed on the axial end of the transmission disk 36 through a one-way transmission member. A cam 27 for pressing the connecting rod 34 is fixedly installed on the outer wall of the transmission ring 25. The one-way transmission member is a one-way clutch. When the transmission disk 36 rotates in the opposite direction, it drives the transmission ring 25 to rotate, thereby driving the cam 27 to rotate. When the cam 27 rotates to press the connecting rod 34, the elastic force exerted on the movable plug 33 controls the reciprocating adjustment of the air pressure in the inner cavity of the storage cylinder 21.

[0055] A drive motor 12 for controlling the rotation of the transmission disk 36 is fixedly mounted on the outer wall of the control box 3 . The drive motor 12 is a waterproof motor, and its output shaft is connected to the worm to control the rotation of the worm wheel and the transmission disk 36 .
