Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of 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.

[0021] Embodiment 1: As Figures 1-3 shown, the present utility model provides a test device for measuring the abrasion rate of silicone rubber, including a bottom plate 1. One side of the upper end of the bottom plate 1 is fixedly provided with a bracket 2. The upper side of one end of the bracket 2 is fixedly provided with a vertical plate 21. The upper and lower sides of one end of the vertical plate 21 are respectively rotatably provided with a second rotating shaft 23 and a first rotating shaft 22. The upper end of the bracket 2 is fixedly provided with a motor 24. The output end of the motor 24 is fixedly connected to the first rotating shaft 22. The outer surfaces of the first rotating shaft 22 and the second rotating shaft 23 are jointly sleeved with a linking belt 25. One end of the second rotating shaft 23 is detachably provided with a rotating column 3. The bottom plate 1 serves as a support and placement structure. After the motor 24 on the bracket 2 is started, its output end drives the first rotating shaft 22 on the vertical plate 21 to rotate. Since the first rotating shaft 22 and the second rotating shaft 23 are connected by the linking belt 25, the rotation of the first rotating shaft 22 will drive the second rotating shaft 23 to rotate through the linking belt 25.

[0022] The outer surface of the rotating column 3 is sleeved and connected with the second rotating shaft 23 and the vertical plate 21, and the rotating column 3 and the second rotating shaft 23 are connected by six bolts. The outer surface of the rotating column 3 is detachably provided with a plurality of half - disks 31. The half - disks 31 serve as components for carrying silicone rubber specimens and rotate with the rotation of the rotating column 3.

[0023] On one side of the upper end of the bottom plate 1, a vertical plate 26 is fixedly provided. On the upper side of one end of the vertical plate 26, a turntable 27 is rotatably provided. At one end of the turntable 27, a cross block 28 is fixedly provided. At one end of the rotating column 3, a cross groove 29 used in cooperation with the cross block 28 is opened. When the second rotating shaft 23 rotates, it will drive the rotating column 3 connected to it by bolts to rotate. The cross groove 29 at one end of the rotating column 3 cooperates with the cross block 28 at one end of the turntable 27. The turntable 27 can rotate on the vertical plate 26, playing a role in supporting and assisting in stabilizing the rotating column 3 to ensure that the rotating column 3 can rotate smoothly. When the second rotating shaft 23 rotates, it will drive the rotating column 3 connected to it by bolts to rotate.

[0024] One end of the opposite surfaces of two vertically corresponding half disks 31 is fitted together. A plurality of clamping blocks 32 are fixedly provided on the outer surface of the rotating column 3, and a clamping member 33 is fixedly provided between two adjacent clamping blocks 32. A clamping groove 34 used in cooperation with the clamping member 33 is opened at the inner end of the half disk 31. Connecting blocks 35 are fixedly provided on both sides at one end of the half disk 31, and the two vertically corresponding connecting blocks 35 are connected by bolts in cooperation. The outer surface of the rotating column 3 is fitted with the clamping groove 34 of the half disk 31 through the clamping blocks 32 and the clamping member 33. At the same time, the vertically corresponding half disks 31 are fixedly connected through the connecting blocks 35 and bolts. In this way, a plurality of half disks 31 can be firmly installed on the rotating column 3. Different numbers of silicone rubber specimens can be installed according to requirements for testing. The power transmission part is simply designed and reliable in use. The rotating structure for carrying the silicone rubber is designed in a detachable connection manner, which facilitates the installation, disassembly and maintenance of the device, and also facilitates the replacement of different carrying rotating structures to adapt to different test requirements.

[0025] Embodiment 2: As Figures 1-4 shown, on one side of the upper end of the bottom plate 1, a cross plate 4 is fixedly provided. On one side of one end of the cross plate 4, a knob 41 is rotatably provided. One end of the knob 41 penetrates through the cross plate 4 and is fixedly provided with a lead screw 42. One end of the vertical plate 26 is fixedly provided with a support block 49, and one end of the lead screw 42 is rotatably connected to the support block 49. One end of the lead screw 42 is rotatably connected to the cross plate 4. A moving plate 43 is threadedly sleeved on the outer surface of the lead screw 42. Two limiting columns 45 are fixedly provided on one side of one end of the cross plate 4. A limiting plate 46 is fixedly provided at the same side end of the two limiting columns 45. The outer surface of the limiting column 45 is sleeved and connected with the moving plate 43. A friction plate 44 is provided at one end of the moving plate 43. The friction plate 44 contacts the surface of the silicone rubber during rotation to measure the wear rate. When it is necessary to adjust the position of the friction plate 44, rotate the knob 41 on the cross plate 4. The knob 41 drives the lead screw 42 to rotate. Since the lead screw 42 is threadedly sleeved with the moving plate 43 and the moving plate 43 is restricted from rotating by the limiting column 45, the rotation of the lead screw 42 will cause the moving plate 43 to move along the axial direction of the lead screw 42. The limiting plate 46 limits the moving range of the moving plate 43, and the support block 49 improves the stability of the rotation of the lead screw 42.

[0026] One end of the friction plate 44 is fixedly provided with two T-shaped sliding bars 47, and two T-shaped sliding grooves 48 for cooperating with the friction plate 44 are opened at one end of the moving plate 43. When the moving plate 43 moves, the friction plate 44 connected to the moving plate 43 through the T-shaped sliding bars 47 and the T-shaped sliding grooves 48 at one end thereof will also move accordingly, so as to adjust the relative position between the friction plate 44 and the upper half plate 31 of the rotating column 3, so as to realize different friction test conditions. In this way, the friction plate 44 can also be replaced, and friction materials of different materials can be replaced according to the quality requirements of the silicone rubber. By adjusting parameters such as the position and pressure of the friction plate 44, the wear conditions of the silicone rubber under a variety of actual use conditions can be simulated, providing more accurate test conditions for the determination of the abrasion rate of silicone rubber in different application fields.

[0027] Working principle: The bottom plate 1 serves as a supporting placement structure. After the motor 24 on the bracket 2 is started, its output end drives the first rotating shaft 22 on the vertical plate 21 to rotate. Since the first rotating shaft 22 and the second rotating shaft 23 are connected by a linkage belt 25, the rotation of the first rotating shaft 22 will drive the second rotating shaft 23 to rotate through the linkage belt 25.

[0028] The half plate 31 serves as a component for carrying the silicone rubber specimen and rotates with the rotation of the rotating column 3.

[0029] When the second rotating shaft 23 rotates, it will drive the rotating column 3 connected to it by bolts to rotate. The cross groove 29 at one end of the rotating column 3 cooperates with the cross block 28 at one end of the turntable 27. The turntable 27 can rotate on the vertical plate 26, playing a role in supporting and assisting the stability of the rotating column 3 to ensure that the rotating column 3 can rotate smoothly. When the second rotating shaft 23 rotates, it will drive the rotating column 3 connected to it by bolts to rotate.

[0030] The outer surface of the rotating column 3 is matched with the card slot 34 of the half plate 31 through the card block 32 and the card part 33. At the same time, the upper and lower corresponding half plates 31 are fixedly connected by the connecting block 35 and bolts. In this way, multiple half plates 31 can be firmly installed on the rotating column 3. Different numbers of silicone rubber specimens can be installed for testing according to needs. The power transmission part is simply designed and reliable in use. The rotating structure for carrying the silicone rubber is designed as a detachable connection method, which facilitates the installation, disassembly and maintenance of the device, and also facilitates the replacement of different carrying rotating structures to meet different test requirements.

[0031] The friction plate 44 contacts the surface of the silicone rubber during rotation to measure the abrasion rate. When it is necessary to adjust the position of the friction plate 44, rotate the knob 41 on the cross plate 4. The knob 41 drives the lead screw 42 to rotate. Since the lead screw 42 is threadedly sleeved with the moving plate 43, and the moving plate 43 is restricted by the limiting column 45 and cannot rotate, the rotation of the lead screw 42 will cause the moving plate 43 to move along the axial direction of the lead screw 42. The limiting plate 46 limits the moving range of the moving plate 43, and the support block 49 improves the stability of the rotation of the lead screw 42.

[0032] When the moving plate 43 moves, the friction plate 44 connected to the moving plate 43 through the T-shaped slide bar 47 and the T-shaped chute 48 will also move accordingly, so as to adjust the relative position between the friction plate 44 and the upper half plate 31 of the rotating column 3 to achieve different friction test conditions. In this way, the friction plate 44 can also be replaced, and friction materials of different materials can be replaced according to the quality requirements of the silicone rubber. By adjusting parameters such as the position and pressure of the friction plate 44, the wear conditions of the silicone rubber under various actual use conditions can be simulated, providing more accurate test conditions for the determination of the abrasion rate of silicone rubber in different application fields.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
