The inner tube is an air-bearing container for inflation and vibration reduction. It is used as an auxiliary air pressure container in the inner cavity of the tire of trucks, motorcycles, bicycles, and rickshaws. It is generally made of butyl rubber.

[0003] During the production process, rubber inner tubes need to have different properties in order to adapt to different usage environments. The maximum puncture force that rubber can withstand is a very important mechanical indicator in industrial applications.

By setting multiple groups of cylinders, the cost of the test equipment is increased. At the same time, because the slide plate is sleeved on the column, during the test, the slide plate is lifted to a certain height, and then the slide plate is loosened, and the impact head hits the rubber. The performance of the rubber is tested by testing the height of the impact head rebound. Because the slide plate contacts the column during the test and has a certain friction, the test accuracy of the rubber inner tube mechanical test is affected. Therefore, it is necessary to design a rubber inner tube mechanical performance testing device to solve the above problems.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] like Figure 1-Figure 2As shown, the present application provides a rubber inner tube mechanical property testing device, comprising a workbench 1, a test bench 2 is fixedly installed on the workbench 1, and a fixed platform 3 is fixedly installed on the test bench 2, and the fixed platform 3 is used to place the rubber inner tube;

[0027] A testing mechanism 4 is installed on the test bench 2, and the testing mechanism 4 is used to test the mechanical properties of the rubber inner tube. The testing mechanism 4 includes two groups of support rods 401 fixedly installed on the test bench 2, a top plate 403 is connected between the two groups of support rods 401, and a linear bearing 402 is slidably mounted on the support rod 401, and the linear bearing 402 is suitable for moving along the linear direction of the support rod 401, so as to be suitable for adjusting the position of the linear bearing 402 on the support rod 401;

[0028] A receiving plate 404 is connected between the two sets of linear bearings 402, a pressure sensor is engaged on one side of the receiving plate 404 close to the top plate 403, and an impact head (not shown in the figure) is fixedly installed on one side of the receiving plate 404 close to the fixed platform 3, and the impact head is suitable for contacting the rubber inner tube to detect the mechanical properties of the rubber inner tube;

[0029] Meanwhile, a column 405 is fixedly mounted on the receiving plate 404. A side of the column 405 close to the top plate 403 has a groove, and a weight 406 is sleeved on the column 405. The column 405 is suitable for restricting the weight 406 to prevent the weight 406 from falling off the receiving plate 404.

[0033] Meanwhile, an adjusting rod 505 is fixedly mounted on the slider 503. The adjusting rod 505 has a movable groove, in which a movable rod 506 is mounted. The movable rod 506 is adapted to move along the linear direction of the movable groove, so as to be adapted to adjust the position of the movable rod 506 in the movable groove.

[0034] At the same time, an insertion rod 508 is inserted on the adjustment rod 505, and the insertion rod 508 has a fixing piece 510, and the fixing piece 510 is used to prevent the insertion rod 508 from falling off the adjustment rod 505, and the fixing piece 510 is attached to the adjustment rod 505, and the insertion rod 508 passes through the movable rod 506 and is inserted on the adjustment rod 505, and at the same time, the movable rod 506 and the adjustment rod 505 are equidistantly provided with plug holes (not shown in the figure) that are adapted to the size of the insertion rod 508, and the movable rod 506 has a connecting surface 507, and a pressing plate 511 is fixedly installed on the connecting surface 507, and at the same time, a fixing pin 509 is inserted on the insertion rod 508, and the fixing pin 509 is used to prevent the insertion rod 508 from falling off the adjustment rod 505;

[0036] In order to initially fix the receiving plate 404, in order to prevent the impact head from being placed on the fixed platform 3 when not in use and causing wear to the contact end thereof, as shown in FIG. Figure 2-Figure 3 As shown, a mounting mechanism is provided on the top plate 403, and the mounting mechanism includes a fixing column 407 fixedly mounted on the top plate 403 near the fixed platform 3, the fixing column 407 has a plurality of circular holes 408, and a spring 409 is fixedly mounted in the circular hole 408, a round buckle block 410 is fixedly mounted on one end of the spring 409 away from the circular hole 408, and a buckle hole matching the size of the round buckle block 410 is opened in the groove;
