[0021] Please refer to Figures 1-5. This utility model provides an embodiment: a rubber tight-ring elasticity testing device, including a storage sleeve 1, a measuring component, and an electromagnetic component.

The measuring column 101 is fixed to the inner wall of the first groove 16, and the positioning rings 102 are uniformly distributed and fixed to the outer wall of the measuring column 101. The third groove 103 is formed on the outer wall of the measuring column 101 and is located close to the measuring column 101. A second limiting groove 104 is provided through one end along the axis, and a fourth groove 105 is provided through both the upper and lower ends of the measuring column 101. A column 106 is slidably mounted on the inner wall of the second limiting groove 104.

Inside the tank 105, when the metal block 109 on the column 106 is attracted upward by magnetic force, and when the attraction stops, the column 106 falls downward under the influence of gravity, touching the lower end of the block 108 and contacting the outer wall of the rubber ring to generate a rebound. Then, the rebound position of the marker column 107 on the measuring column 101 is recorded. By setting multiple measuring components, multiple rubber rings can be tested simultaneously, and then the average value is taken, thereby realizing the test of the elasticity of the rubber ring, improving the accuracy and efficiency of the test.

[0022] Please refer to Figures 1-3. In this embodiment, the front end of the storage sleeve 1 has a placement groove 3. First limiting grooves 2 are provided on the left and right ends of the inner wall of the placement groove 3 on the storage sleeve 1. A first magnet 4 is provided on the rear end of the storage sleeve 1 at the placement groove 3. A first fixing block 5 is fixedly connected to the upper end of the storage sleeve 1. A stop block 6 is fixedly connected to the front end of the first fixing block 5. The stop block 6 passes through the inner ring of the rubber ring placed in the storage groove 13, thereby fixing the rubber ring while simultaneously blocking and supporting the lower part of the rubber ring protruding from the storage groove 13, thus facilitating subsequent testing. A storage block 10 is slidably arranged on the placement groove 3. A second magnet 12 is provided at the rear end of the storage block 10. The rear end of the second magnet 12 and the front end of the first magnet 4 are mutually attached and attracted to each other. The first magnet 4 on the sleeve 1 attracts the second magnet 12 on the storage block 10, thereby fixing the storage block 10 on the storage sleeve 1. The outer walls of the left and right ends of the storage block 10 are fixed with the first limiting block 11, which is adapted to the first limiting groove 2. The upper end of the storage block 10 is provided with a storage groove 13. The front end of the storage block 10 is fixed with the handle 14. The lower end of the stop block 6 is in contact with the upper end of the storage block 10. The outer wall of the left end of the storage sleeve 1 is fixed with the second fixing block 7. The upper end of the second fixing block 7 is fixed with the placement platform 8. The placement platform 8 is equipped with a high-speed camera 9. The camera end of the high-speed camera 9 faces the L-shaped connecting frame 15. The high-speed video captured by the high-speed camera 9 can effectively record the up and down rebound position of the marker column 107 on the measuring column 101.

[0023] Please refer to Figures 1 and 4. In this embodiment, an electromagnetic assembly is provided on the connecting frame 15. The electromagnetic assembly includes a connecting block 18, a PCB board 19, a battery 20, wire strips 21, a coil 22, and a magnetic core 23. The right end of the connecting block 18 is fixedly connected to the PCB board 19. The battery 20 is provided on the PCB board 19. The PCB board 19 is provided with evenly distributed wire strips 21. The number of wire strips 21 corresponds one-to-one with the number of measuring columns 101 in the measuring assembly. The upper end of the measuring column 101 is fixedly connected to the coil 22, and the lower end of the coil 22 is provided with... There is a magnetic core 23, the outer wall of which is in contact with the upper part of the inner wall of the fourth groove 105. The coil 22 and the wire strip 21 are electrically connected to each other. The PCB board 19 can control the start and stop of multiple coils 22. The battery 20 can provide power to the coils 22. When the coil 22 is turned on, the magnetic core 23 attracts the metal block 109 in the fourth groove 105, so that the column 106 can move upward in the second limiting groove 104. When the coil 22 is turned off, the column 106 moves downward under the force of gravity to perform an elasticity test.

[0024] First, the rubber ring to be tested is placed into the storage slot 13 on the storage block 10. Then, the first limiting block 11 on the storage block 10 is slid into the first limiting slot 2 on the storage sleeve 1, causing the first magnet 4 and the second magnet 12 to attract each other, thereby fixing the storage block 10 in the placement slot 3 on the storage sleeve 1. During the sliding insertion, the stop block 6 passes through the inner ring of the rubber ring placed in the storage slot 13, thereby fixing the rubber ring and supporting the lower part of the rubber ring protruding from the storage slot 13, thus facilitating subsequent testing. When the storage block 10 is placed in the placement slot 3, by... The coil 22 is made conductive, causing the magnetic core 23 to attract the metal block 109 in the fourth groove 105 upwards, and the column 106 to slide upwards on the inner wall of the second limiting groove 104. Then, the high-resolution camera 9 is turned on, and the power supply to the coil 22 is stopped, causing the column 106 on the measuring column 101 to fall downwards under the influence of gravity. When falling, it rebounds through the contact of the contact block 108 with the outer wall of the rubber ring, causing the high-resolution camera 9 to record the bounce of the positioning column 107 on the measuring column 101, thereby testing the elasticity of the rubber ring. The average value can be calculated by the multiple measuring components to detect whether the product meets the standard.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
