However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0023] 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.

[0024] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0025] In order to solve the problem that the scraper of the tire anti-leakage self-sealing adhesive test device is very likely to shake when testing the self-sealing adhesive, resulting in uneven thickness of the self-sealing adhesive and reducing the test accuracy of the self-sealing adhesive, please refer to Figures 1 to 4 The structure of the device body is a test bench 1, an electronic universal testing machine body 3 for testing the self-sealing glue, and a heating test plate 4. The heating test plate 4 is energized by an external device to heat the self-sealing glue on its top. The self-sealing glue is squeezed and retracted by the extension and contraction of the pressure head of the electronic universal testing machine body 3. The maximum force obtained by the test is evaluated as the adhesion strength of the self-sealing glue by recording the changes in displacement and force. The greater the force value, the higher the quality of the self-sealing glue. The bottom end of the heating test plate 4 is fixedly connected to the test bench 1. The set test bench 1 provides support for the heating test plate 4. Linear motors 5 are installed at both ends of the top of the test bench 1. The set linear motor 5 provides power. The moving part of the linear motor 5 is fixedly connected to the fixed plate 6, which is convenient for the moving part of the linear motor 5 to drive the fixed plate 6 to move its position.

[0026] The side of the fixed plate 6 is fixedly connected with a sliding bar 7 through a through groove, so that the top and bottom ends of the sliding bar 7 are fixedly connected to the fixed plate 6, and a sliding plate 8 is slidably connected to the side of the sliding bar 7, so that the sliding plate 8 can move longitudinally along the path of the sliding bar 7, thereby improving the movement stability of the sliding plate 8. Both sides of the sliding plate 8 are slidably connected to the fixed plate 6 to further improve the movement stability of the sliding plate 8, thereby preventing the sliding plate 8 from shaking during the movement of the sliding plate 8, thereby improving the structural stability of the device. The two sliding plates 8 are fixedly connected with a moving plate 9 on the adjacent sides, and the bottom and top ends of the moving plate 9 are respectively fixedly connected with a scraper 10 and a pulling plate 11. The self-sealing glue heated at the top of the heated test plate 4 is flattened by the set scraper 10. At the same time, the fixed plate 6 and the sliding bar 7 that are set improve the longitudinal movement stability of the sliding plate 8, and prevent the scraper 10 from shaking when the self-sealing glue is flattened under the drive of the moving part of the linear motor 5, thereby reducing the uniformity of the flattened thickness of the self-sealing glue, thereby achieving the improvement of the test accuracy of the performance test device for the self-sealing glue.

[0027] The pull plate 11 is set in a U-shaped inverted state, which is convenient for pulling the pull plate 11 to make the movable plate 9 move longitudinally, and then control the longitudinal height of the scraper 10, so as to control the test thickness of the self-sealing glue and improve the convenience of using the device. The end of the slide plate 8 away from the movable plate 9 is threadedly connected with a bolt 12, and the end face of the bolt 12 is fixedly connected with a rubber block 13, and the end face of the rubber block 13 is in contact with the slide bar 7. The set bolt 12 drives the rubber block 13 to move along the threaded path of the slide plate 8, so that the rubber block 13 is in close contact with the slide bar 7, so as to fix the position of the slide plate 8, prevent the scraper 10 from shaking longitudinally when flattening the self-sealing glue, resulting in uneven flattening thickness of the self-sealing glue, and further improve the test accuracy of the performance testing device for the self-sealing glue.

[0028] A U-shaped inverted support plate 2 is fixedly connected to the two sides of the test bench 1, and the bottom end of the support plate 2 is fixedly connected to the main body 3 of the electronic universal testing machine. The support plate 2 is set to fix the position of the main body 3 of the electronic universal testing machine. Four equidistantly arranged support rods 14 are fixedly connected to the bottom end of the test bench 1. The set support rods 14 provide preliminary support for the test bench 1. The bottom end of the support rod 14 is slidably connected to a movable plate 15 through an inner cavity. The inner cavity of the support rod 14 is square, and the movable plate 15 is square to prevent the movable plate 15 from rotating when moving along the inner cavity of the support rod 14, thereby improving the functional structural stability of the device. A threaded rod 16 is fixedly connected to the bottom end of the movable plate 15 to achieve synchronous movement of the movable plate 15 and the threaded rod 16. The threaded rod 16 is threadedly connected to a threaded ring 18, so that the threaded rod 16 moves along the threaded path of the threaded ring 18. The side of the threaded ring 18 is rotatably connected to the support rod 14, and the top end of the threaded ring 18 extends into the interior of the support rod 14. The top end of the threaded ring 18 is fixedly connected to the inner ring of the limited bearing 20.

[0029] The outer ring side of the limit bearing 20 is fixedly connected to the support rod 14. The limit bearing 20 is set to fix the rotation position of the threaded ring 18, and at the same time it is convenient to realize the relative rotation of the threaded ring 18 and the support rod 14, so as to realize the adjustment of the extension length of the threaded rod 16 and the support rod 14 to prevent the ground from being uneven. During the transmission process, the heating test plate 4 is tilted, causing the self-sealing glue at the top of the heating test plate 4 to flow under the action of gravity, making the thickness of the self-sealing glue uneven, and reducing the test accuracy of the performance test device for the self-sealing glue. Push plates 19 are fixedly connected at both ends of the outer ring surface of the threaded ring 18. The set push plates 19 facilitate the rotation of the threaded ring 18 and improve the convenience of using the device. The bottom end of the threaded rod 16 is fixedly connected to the base 17. The set base 17 increases the contact area with the ground and improves the support stability.

[0030] The linear motor 5 is a prior art, and its working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] How it works

[0032] When using the device for testing the adhesion performance of the tire leak-proof self-sealing adhesive, the user places the self-sealing adhesive on the top of the heating test plate 4 for heating testing, rotates the bolt 12 to release the rubber block 13 from fixing the position of the slide plate 8, pulls the pull plate 11, and moves the slide plate 8 along the path of the slide bar 7 during the transmission process. At the same time, both sides of the slide plate 8 are slidably connected with the fixed plate 6 to improve the stability of the movement path of the slide plate 8, thereby controlling the flattening thickness of the self-sealing adhesive by the scraper 10, and realizing accurate testing of the self-sealing adhesive. By rotating the bolt 12, the bolt 12 drives the rubber block 13 It extends into the interior of the slide plate 8 and contacts with the slide rod 7 to fix the position of the slide plate 8. During the transmission process, the scraper 10 is prevented from shaking when it is flattening the self-sealant, resulting in uneven thickness of the self-sealant and reducing the test accuracy of the performance testing device for the self-sealant. After the self-sealant is flattened, the pressure head of the electronic universal testing machine body 3 supported and fixed by the support plate 2 is telescopically moved to squeeze and retract the self-sealant on the top of the heated test plate 4. By recording the changes in displacement and force, the maximum force obtained by the test is evaluated as the test adhesion of the self-sealant. The larger the force value, the higher the quality.

[0033] When the performance testing device is used on an uneven ground, the heating test plate 4 is prevented from tilting due to the uneven ground, causing the self-sealing glue at the top thereof to flow under the action of gravity, resulting in uneven thickness of the self-sealing glue, thereby reducing the testing accuracy of the self-sealing glue of the performance testing device. By pushing the push plate 19, the threaded rod 16 is moved along the threaded path of the threaded ring 18. During the transmission process, the extension length of the threaded rod 16 and the support rod 14 are controlled to achieve horizontal support for the performance testing device, thereby improving the convenience of the device and the testing accuracy of the self-sealing glue. The limit bearing 20 is set to fix the rotation position of the threaded ring 18, and at the same time realize the relative rotation of the threaded ring 18 and the support rod 14, so that the threaded rod 16 drives the square movable plate 15 to move in the square inner cavity of the support rod 14, thereby preventing the movable plate 15 from rotating while improving the movement stability of the threaded rod 16 and improving the functional structural stability of the device.
