At the same time, it has good wear resistance and heat resistance, improves service life, and is highly practical. The above utility model can replace the components separately after long-term use and aging, avoiding the capital cost of overall replacement. At the same time, the device has certain wear resistance, which reduces the capital expenditure to a certain extent. However, although rubber itself is an insulator, a certain amount of charge will be accumulated on its surface due to long-term friction, which will cause sparks to be easily generated during long-term use of rubber, resulting in damage to the rubber. Therefore, it is necessary to design an antistatic coated rubber roller. Utility Model Content

[0010] Preferably, a fixing screw is provided on one side of the exterior of the telescopic rod 1, and the fixing screw is threadedly connected to the telescopic rod 1.

[0011] Preferably, a limit seat is arranged above the second telescopic rod, and a rotating rod is arranged inside the limit seat, and the rotating rod is rotatably connected to the limit seat.

[0016] The electrons generated by extrusion inside the rubber layer will be transmitted to the antistatic coating through the heat-resistant layer and neutralized in the antistatic coating. At the same time, the electrons generated by external friction cannot pass through the antistatic coating to enter the rubber roller and contact the rubber layer, so that the rubber layer is isolated from the outside. At the same time, if the electrons of the rubber layer move downward through the fixed sleeve to the outside of the insulating layer, they can be isolated by the insulating layer to avoid sparks generated by contact between the electrons and the metal axis, so that the inside of the rubber roller is in an almost oxygen-free state, reducing the probability of sparks generated by electronic contact. At the same time, the fixed sleeve can play a certain supporting and fixing role between the rubber layer and the metal axis, so that the rubber roller can maintain a certain stability when rolling.

The antistatic coating 6 can have a certain insulating effect on the electrons generated by the rubber roller when rolling, so as to prevent the electrons from entering the inside of the rubber roller and contacting the rubber layer 4. At the same time, the heat-resistant layer 5 can isolate the rubber layer 4 from the external temperature in hot seasons, thereby reducing the possibility of the external temperature being transmitted to the rubber layer 4, thereby reducing the possibility of the rubber layer 4 melting. At the same time, the sealing cover 7 can seal the rubber layer 4 inside the rubber roller, so that the inside of the rubber roller is in an almost oxygen-free state, reducing the probability of sparks generated by electronic contact. At the same time, the fixed sleeve 3 can play a certain supporting and fixing role between the rubber layer 4 and the metal axis 1, so that the rubber roller can maintain a certain stability when rolling.

[0026] like Figure 1-5As shown, a mounting hole 9 is provided inside the fixed shaft 8, and the mounting hole 9 and the fixed shaft 8 are an integrated structure, a telescopic rod 10 is provided outside the fixed shaft 8, and the telescopic rod 10 is distributed around the central axis of the fixed shaft 8, four telescopic rods 10 are provided, a telescopic rod 2 11 is provided inside the telescopic rod 10, and the telescopic rod 10 and the telescopic rod 2 11 are slidably connected, a fixing screw 12 is provided on one side of the outside of the telescopic rod 10, and the fixing screw 12 and the telescopic rod 10 are threadedly connected, a limited seat 13 is provided above the telescopic rod 2 11, and a rotating rod 14 is provided inside the limiting seat 13, and the rotating rod 14 is rotatably connected to the limiting seat 13, a rotating seat 15 is provided above the outside of the rotating rod 14, and the rotating seat 15 is rotatably connected to the rotating rod 14, a limited block 16 is provided above the rotating seat 15, and the left side of the limited block 16 An arc-shaped limit rod 17 is provided at the lower side, and a pressing handle 18 is provided at the rear of the limit block 16, and a spring 19 is provided below the pressing handle 18. The mounting hole 9 can be engaged with the rotating shaft of the component to be installed to prevent the rotating shaft from sliding when rotating. At the same time, a groove is provided inside the telescopic rod 11 to ensure that the telescopic rod 11 and the telescopic rod 1 10 can be fixed together by rotating the fixing screw 12. At the same time, the diameter of the component engaged with the rubber roller can be increased by sliding between the telescopic rod 10 and the telescopic rod 1 11. At the same time, the arc-shaped limit rod 17 inside the limit block 16 can prevent the mounting seat from sliding when it is fixedly engaged with the mounting seat outside the rotating shaft, so that the rubber roller can be more stable when fixed. At the same time, the optimal fixing size of the limit block 16 and the mounting seat can be detected by sliding the telescopic rod 11 and the telescopic rod 1 10.

[0027] In this embodiment, when in use, the fixing screw 12 can be firstly rotated to separate the telescopic rod 11, so that the telescopic rod 11 is loose, and then the limit block 16 above the telescopic rod 10 is moved so that the limit block 16 is away from the component to be connected, so that a distance is generated between the limit block 16 and the component to be connected, which facilitates the connection of the component with the mounting hole 9, and then the mounting hole 9 inside the fixed shaft 8 is aligned with the mouth of the component to be connected, so that the rotating shaft of the component is engaged with the mounting hole 9, and then the telescopic rod 11 is rotated to the right by sliding. The movable shaft is moved in the direction of the mounting seat outside, so that the bottom surface of the arc-shaped limiting rod 17 inside the limiting block 16 contacts the mounting seat, and then the telescopic rod 10 and the telescopic rod 2 11 are fixed together by rotation, so that the limiting block 16 is fixed. At this time, the pressing handle 18 is pressed, so that the pressing handle 18 starts to squeeze the spring 19, and the right side of the pressing handle 18 starts to move downward, so that the rotating seat 15 starts to rotate to the lower right direction. At the same time, the rotating rod 14 and the rotating seat 15 are rotatably connected, and the rotating rod 14 is rotatably connected, so that the rotating seat 15 can be rotated to the right with the rotating rod 14 as the fulcrum. The rubber roller 16 is moved so that the mouth of the limit block 16 is larger than the diameter of the mounting seat outside the rotating shaft. At this time, the rubber roller is pressed to the left so that the bottom right side of the mounting hole inside the fixed shaft 8 contacts and fixes with the rotating shaft. At the same time, the pressing handle 18 can be loosened so that the spring 19 returns to its original state, so that the limit block 16 returns to a horizontal state, so that the bottom of the arc-shaped limit rod 17 inside the limit block 16 is fixed to the bottom surface of the mounting seat groove. At this time, the right side of the rubber roller can be fixed in the same way as the left side, and then the rubber roller is fixed to the component to be installed. At the same time, the component can be started to measure. The stability performance of the rubber roller was tested. After the device was rolled for a long time, the electrons generated by extrusion inside the rubber layer 4 would be transmitted to the antistatic coating 6 through the heat-resistant layer 5 and neutralized in the antistatic coating 6. At the same time, the electrons generated by friction outside could not pass through the antistatic coating 6 to enter the rubber roller and contact the rubber layer 4, so that the rubber layer 4 was isolated from the outside. At the same time, if the electrons of the rubber layer 4 moved downward through the fixed sleeve 3 to the outside of the insulating layer 2, they could be isolated by the insulating layer 2 to avoid the electrons from contacting the metal axis 1 to generate sparks, so that the rubber roller could maintain a certain insulating state for rolling.
