[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0027] like Figures 1 to 4 An inflatable explosion-proof testing device for tire production is shown, comprising a workbench 1. The bottom surface of the workbench 1 can be installed with universal wheels for easy movement to the work point. A groove 2 is provided on the top surface of the workbench 1. The groove 2 is arranged in an approximately square shape. A rotating block 3 is provided in the inner cavity of the groove 2. The tire to be tested can be placed on the top surface of the rotating block 3. The top surface of the rotating block 3 is higher than the top surface of the groove 2. The diameter of the groove 2 is larger than the width of the rotating block 3, so that the rotating block 3 can rotate in the inner cavity of the groove 2.

[0028] A driving motor 12 is fixedly installed on the bottom surface of the inner cavity of the groove 2, and the driving motor 12 can rotate forward and reverse. The output shaft of the driving motor 12 is fixedly connected to the bottom surface of the rotating block 3. When the driving motor 12 is turned on, the driving motor 12 can drive the rotating block 3 to rotate in the inner cavity of the groove 2, and then drive the tire to rotate. A transverse plate 13 is fixedly installed on the inner wall of the circumferential side of the groove 2 and between the rotating block 3 and the driving motor 12. A circular groove 14 is opened on the top surface of the transverse plate 13. The circular groove 14 is arranged in a circle on the top surface of the transverse plate 13 with the output shaft of the driving motor 12 as the axis. A plurality of rolling balls 15 are placed in the inner cavity of the circular groove 14, and the top surface of each rolling ball 15 is against the bottom surface of the rotating block 3. When the driving motor 12 drives the rotating block 3 to rotate, the rotating block 3 will rotate on the top surfaces of multiple rolling balls 15, so that the multiple rolling balls 15 can assist the rotating block 3 to rotate.

[0029] A left clamping plate 4 is fixedly installed on one side of the top surface of the rotating block 3, and a right clamping plate 5 is arranged on the other side of the top surface of the rotating block 3. Both the left clamping plate 4 and the right clamping plate 5 are arranged as arc-shaped blocks, so that they can better abut the inner wall of the tire rim. After the tire to be tested is placed on the top surface of the rotating block 3, the left clamping plate 4 and the right clamping plate 5 can be placed inside the tire bead. The bottom surface of the right clamping plate 5 is fixedly connected with a connecting block 6, and the bottom end of the connecting block 6 passes through the inner cavity of the rotating block 3, so that the bottom end of the connecting block 6 will be in the upper half of the inner cavity of the rotating block 3, and the top surface of the rotating block 3 is located A slide groove 10 for the movement of the connecting block 6 is laterally opened below the right splint 5, so that the connecting block 6 can move laterally in the inner cavity of the slide groove 10, so that the connecting block 6 can drive the right splint 5 to move laterally on the top surface of the rotating block 3, thereby changing the distance between the left splint 4 and the right splint 5. The inner walls on both sides of the slide groove 10 are fixedly connected with sliding rods 11, and the connecting block 6 is slidably sleeved on the surrounding side of the sliding rod 11, thereby ensuring that the connecting block 6 will always move in the inner cavity of the slide groove 10, so that the right splint 5 can only move laterally along the slide groove 10.

[0030] A hydraulic cylinder 7 is fixedly installed on the bottom surface of the inner cavity of the rotating block 3 and below the left clamping plate 4. The piston rod of the hydraulic cylinder 7 is fixedly connected to a rectangular block 8. A connecting rod 9 is hinged on the top surface of the rectangular block 8. The free end of the connecting rod 9 is hinged to the bottom surface of the connecting block 6. When the left clamping plate 4 and the right clamping plate 5 are put into the inner cavity of the tire bead, the hydraulic cylinder 7 is turned on to drive the rectangular block 8 to move longitudinally, so that the rectangular block 8 can drive the connecting rod 9 to move. Since the free end of the connecting rod 9 is hinged to the connecting block 6, and the connecting block 6 can only move laterally due to the restriction of the sliding rod 11, when the hydraulic cylinder 7 drives the rectangular block 8 to move upward, the rectangular block 8 will push the connecting block 6 through the connecting rod 9, so that the connecting rod 9 is in an inclined state, and the connecting block 6 can drive the right clamping plate 5. Move in the direction away from the left clamping plate 4, so that the right clamping plate 5 can fit the inner wall of one side of the tire bead and push the tire to move, so that the inner wall of the other side of the tire bead can press against the left clamping plate 4, and the left clamping plate 4 and the right clamping plate 5 can press against the inner walls of the two sides of the tire respectively, so that the tire can be fixed. Conversely, when the rectangular block 8 moves downward, the rectangular block 8 pulls the connecting block 6 through the connecting rod 9, so that the connecting rod 9 gradually becomes vertical, so that the connecting rod 9 drives the connecting block 6 and the right clamping plate 5 to move toward the left clamping plate 4, so as to change the distance between the left clamping plate 4 and the right clamping plate 5, so that the left clamping plate 4 and the right clamping plate 5 can fix tires of different sizes, avoid only fixing tires of one size, and improve the efficiency of tire testing.

[0031] Fixed plates 16 are fixedly installed on both sides of the top surface of the workbench 1, and cylinders 17 are fixedly installed on the opposite sides of the two fixed plates 16. The piston rods of the two cylinders 17 are fixedly connected with puncture needles 18 for puncturing the tire. When the tire is fixed on the top surface of the rotating block 3, the two cylinders 17 are turned on, and the two cylinders 17 are respectively driven by the two cylinders 17 to move toward the tire, so that the two puncture needles 18 are pierced into the tire to perform a puncture test on the tire, and in conjunction with the rotation of the rotating block 3, the puncture test can be performed on the circumferential side of the tire. After the puncture is completed, the tire is removed and placed in an external water tank to allow water to overflow the tire and observe whether bubbles appear in the water to refer to the inflation and explosion-proof quality of the tire.

[0032] Working principle:

[0033] The inflatable explosion-proof test device for tire production is to place the tire in need at this time on the top surface of the rotating block 3, and make the left clamping plate 4 and the right clamping plate 5 both in the tire bead, and then open the hydraulic cylinder 7 to make the hydraulic cylinder 7 drive the rectangular block 8 to move longitudinally, so that the rectangular block 8 drives the connecting rod 9 to move, and because the free end of the connecting rod 9 is hinged to the connecting block 6, when the rectangular block 8 moves upward, it will gradually drive the connecting rod 9 to move away from the end of the rectangular block 8, so that the connecting rod 9 can gradually present an inclined style, that is, the connecting block 6 can be The right clamping plate 5 is driven to move so that the right clamping plate 5 fits against the inner wall of one side of the tire bead, and the tire is pushed to move so that the inner wall of the other side of the tire bead can be against the left clamping plate 4, so that the left clamping plate 4 and the right clamping plate 5 can respectively press against the inner walls of both sides of the tire bead, thereby completing the fixation of the tire and facilitating the subsequent puncture test. Since the right clamping plate 5 can be moved on the top surface of the rotating block 3, tires of different sizes can be fixed, avoiding the test device only being able to test tires of the same size, thereby improving the efficiency of tire testing.
