Description

Technical Field

[0001] The utility model relates to the technical field of football elasticity detection, in particular to a football elasticity detection device. Background Technique

[0002] Football is a sport that mainly uses feet to control and dominate the ball. Two teams play offensive and defensive confrontations on the same rectangular field according to certain rules. Due to the characteristics of strong confrontation, changeable tactics, and a large number of participants in football, it is known as the "world's first sport". During the production of football, a detection device is usually used to detect the elasticity of the football.

[0003] During the process of using the detection device to detect the football, the football is usually made to fall freely, and then the height of the football bouncing up is observed to detect the elasticity of the football. However, during the detection process, universal wheels are usually installed at the bottom of the device for easy movement, which may cause instability of the whole when the football is in free fall. At the same time, the existing floor is usually directly fixed on the top of the base. After the floor is subjected to the free fall of the football for a long time, it is very easy to be damaged, and it is not convenient to replace the floors of different materials for detection.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Referring to Figures 1-4 , the present utility model provides a technical solution, a football elasticity detection device, including a base 1. Four groups of universal wheels 18 are arranged at the bottom of the base 1 and are arranged in an array. A box body 2 is fixedly installed on the top of the base 1. A glass door 19 is hinged to the front of the box body 2. A handle 20 is fixedly installed on the front of the glass door 19. A scale line 21 is fixedly installed on the front of the box body 2. A slide rail 6 is installed on the top of the box body 2 through a lifting mechanism. The lifting mechanism includes a first motor 3 fixedly installed on the top of the box body 2. The output end of the first motor 3 is fixedly installed with a lead screw 4. A first moving block 5 is threadedly sleeved on the surface of the lead screw 4. One side of the first moving block 5 and one side of the slide rail 6 are fixedly installed, which is convenient for driving the slide rail 6 to move. A chute 22 is opened on the inner wall of the box body 2. The inner wall of the chute 22 is fitted with the surface of the first moving block 5 to limit the first moving block 5, making the movement of the first moving block 5 more stable. A moving plate 10 is installed on the inner wall of the slide rail 6 through a moving mechanism. The moving mechanism includes a second motor 7 fixedly installed on the inner wall of the slide rail 6. The output end of the second motor 7 is fixedly installed with a bidirectional threaded rod 8. A second moving block 9 is threadedly sleeved on the surface of the bidirectional threaded rod 8. The bottom of the second moving block 9 and the top of the moving plate 10 are fixedly installed, which is convenient for driving the moving plate 10 to move.

[0023] Specifically, a clamping plate 11 is fixedly installed on one side of the moving plate 10. The number of the second moving blocks 9, the moving plates 10 and the clamping plates 11 is two groups and they are symmetrically arranged. A notch 12 is opened at the bottom of the inner wall of the box body 2, a positioning groove 13 is opened on the inner wall of the notch 12, and a placing plate 14 is slidably installed on the inner wall of the positioning groove 13. One side of the base 1 is fixedly installed with a mounting plate 15, and a supporting mechanism is arranged on the top of the mounting plate 15. The supporting mechanism includes an electric push rod 16 fixedly installed on the top of the mounting plate 15, and a supporting plate 17 is fixedly installed at the output end of the electric push rod 16. The base 1 can be driven to move through the universal wheels 18. After moving to the designated position, the supporting plate 17 is driven to descend through the electric push rod 16, and then the base 1 can be supported by the supporting plate 17, making the subsequent football detection more stable. By driving the two clamping plates 11 to move towards each other through the second motor 7, the football can be clamped by the two clamping plates 11. By driving the football to rise and fall through the first motor 3, the football can be driven to the designated height. By driving the two clamping plates 11 to move in the opposite direction through the second motor 7, the football can be released, making the football do a free fall motion. The football falls onto the top of the placing plate 14 and rebounds through the elasticity of the football. By comparing the scale lines 21, the height of the football rebound can be detected, and then the elasticity of the football can be obtained. By pulling out the placing plate 14, the placing plate 14 can be taken out, and then a new placing plate 14 is inserted into the inner wall of the positioning groove 13, and the placing plate 14 can be replaced. The purpose of facilitating the support and movement of the base 1 is achieved, making the football test more stable. At the same time, it is convenient to replace the placing plate 14, so that different materials of floors can be used to detect the elasticity of the football. The structure is simple and easy to use.

[0024] The electrical components appearing in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0025] During use: When using this football elasticity detection device, the base 1 can be driven to move through the universal wheels 18. After moving to the designated position, the support plate 17 is driven to descend by the electric push rod 16, and then the support plate 17 can be used for support, making the subsequent football detection more stable. By placing the football between the two sets of clamping plates 11, the bidirectional threaded rod 8 is driven to rotate by the second motor 7. The bidirectional threaded rod 8 drives the two sets of second moving blocks 9 to move towards each other. The second moving blocks 9 drive the two sets of moving plates 10 to move towards each other. The moving plates 10 drive the two sets of clamping plates 11 to move towards each other, and then the football can be clamped by the two sets of clamping plates 11. After clamping, the lead screw 4 is driven to rotate by the first motor 3. The lead screw 4 drives the first moving block 5 to move up and down. The first moving block 5 drives the slide rail 6 to move up and down. The slide rail 6 drives the football to move up and down, and then the football can be driven to the designated height. The glass door 19 is closed, and the two sets of clamping plates 11 are driven to move in the opposite direction by the second motor 7, so as to loosen the football, making the football do a free fall motion. The football falls onto the top of the placement plate 14 and rebounds due to the elasticity of the football. By comparing the scale lines 21, the rebound height of the football can be detected, and then the elasticity of the football can be obtained. By pulling out the placement plate 14, the placement plate 14 can be taken out, and then a new placement plate 14 is inserted into the inner wall of the positioning groove 13, so as to replace the placement plate 14. It achieves the purpose of facilitating the support and movement of the base 1, making the football test more stable.
