The first connecting rod is welded to the right side of the first mounting rod, and the first connecting rod is connected to the left side of the transmission roller. The outer surface of the transmission roller is meshed with the inner surface of the composite rubber roller sleeve. The right side of the transmission roller is connected to the second connecting rod, and the second mounting rod is welded to the right side of the second connecting rod. However, in the above patent, when using the printing rubber roller, it is necessary to put a sleeve on the rotating shaft to protect the rotating shaft of the printing rubber roller. Since the sleeve is usually directly put on the outer wall of the rotating shaft, due to the lack of a limiting mechanism, the sleeve will deviate from the outer wall of the rotating shaft, and there is a possibility of falling off.

[0004] Therefore, in view of the above problems, an electrostatic printing rubber roller with a detachable shaft sleeve is proposed. Utility Model Content

[0028] Example:

[0029] See also Figure 1-4 , a kind of electrostatic printing rubber roller with a detachable sleeve, comprises a rotating shaft 1 and a rubber roller body 11, a mounting hole 12 is opened in the middle of the rubber roller body 11, the rotating shaft 1 is fixedly connected to the inside of the mounting hole 12, the outer wall of the rotating shaft 1 is slidably connected to the sleeve body 14, and a fixing mechanism 2 is arranged inside the rotating shaft 1, the fixing mechanism 2 comprises a sliding plate 21, the sliding plate 21 is slidably connected to the outer wall of the rotating shaft 1, and the outer wall of the rotating shaft 1 is sleeved with a No. 1 spring 22, and the No. 1 spring 22 is located between the rotating shaft 1 and the sliding plate 21. In this scheme, when the sliding plate 21 slides along the direction of the end of the rotating shaft 1, the side of the sliding plate 21 close to the rotating shaft 1 will squeeze the No. 1 spring 22, and the No. 1 spring 22 will undergo elastic deformation and compression after being squeezed and store a certain amount of elastic potential energy, and when the end of the sliding plate 21 slides to fit the rotating shaft 1, the sliding plate 21 can release the blockage of the top block 26.

[0030] See also Figure 1-4The interior of the rotating shaft 1 is slidably connected with a slide rod 23, one end of the slide rod 23 is fixedly connected to a limiting block 24, and the other end of the slide rod 23 is fixedly connected to a top block 26. In this solution, when the sliding plate 21 releases the blockage of the top block 26, the slide rod 23 can slide with the top block 26 toward the outside of the rotating shaft 1.

[0031] See also Figure 1-4 The outer wall of the slide bar 23 is sleeved with a No. 2 spring 25, and the No. 2 spring 25 is located between the top block 26 and the rotating shaft 1. In this solution, when the sliding plate 21 completes the blocking of the top block 26 inside the rotating shaft 1, the top block 26 will squeeze the No. 2 spring 25 and cause the No. 2 spring 25 to undergo elastic deformation and compression and store a certain amount of elastic potential energy. When the sliding plate 21 releases the blocking of the top block 26, the No. 2 spring 25 in the compressed state is reset, driving the slide bar 23 to slide toward the outside of the rotating shaft 1.

[0032] See also Figure 1-4 The outer wall of the sleeve body 14 is provided with a limiting groove 15, and the limiting block 24 is clamped inside the limiting groove 15. In this solution, since the end of the limiting block 24 is provided with a chamfer, when the end of the sleeve body 14 is inserted into the interior of the rotating shaft 1, the chamfer provided by the limiting block 24 will be squeezed, so that the sliding rod 23 slides toward the outside of the rotating shaft 1.

[0033] See also Figure 1-4 A positioning groove 13 is formed on the outer wall of the rotating shaft 1, and a fixing block 16 is fixedly connected to the inside of the sleeve body 14. In this solution, the positioning groove 13 and the fixing block 16 play a positioning role in the installation between the sleeve body 14 and the rotating shaft 1.

[0034] See also Figure 1-4 , six slide bars 23 are evenly distributed inside the rotating shaft 1, and both ends of the six slide bars 23 are fixedly connected to the limiting blocks 24 and the top blocks 26. In this solution, the six limiting blocks 24 are all clamped inside the limiting grooves 15 to facilitate the fixation between the sleeve body 14 and the rotating shaft 1.

[0035] See also Figure 1-4 The fixing block 16 is slidably connected to the inside of the positioning groove 13. In this solution, the fixing block 16 is slidably connected to the inside of the positioning groove 13, so that the sleeve body 14 can be rotated and the rotating shaft 1 can be driven to rotate at the same time.

[0036] Working principle: If the user needs to install between the sleeve body 14 and the rotating shaft 1, the sliding plate 21 can be moved along the direction of the end of the rotating shaft 1. When the sliding plate 21 slides along the direction of the end of the rotating shaft 1, the side of the sliding plate 21 close to the rotating shaft 1 will squeeze the No. 1 spring 22. After being squeezed, the No. 1 spring 22 will be elastically deformed and compressed and store a certain amount of elastic potential energy. When the end of the sliding plate 21 slides to fit the rotating shaft 1, the sliding plate 21 can release the blockage of the top block 26, and then the sleeve body 14 is inserted into the interior of the rotating shaft 1. During the insertion process, because the end of the limit block 24 is chamfered, the end of the sleeve body 14 will be inserted into the interior of the rotating shaft 1. The chamfered corner of the limit block 24 is squeezed to make the slide bar 23 slide toward the outside of the rotating shaft 1. As the sleeve body 14 is gradually inserted, when the limit groove 15 moves to the bottom of the limit block 24, the sliding plate 21 is moved again to reset it. The sliding plate 21 will squeeze the top block 26. After being squeezed, the top block 26 will drive the slide bar 23 to slide toward the inside of the rotating shaft 1, so that the limit block 24 is clamped in the inside of the limit groove 15. In addition, by blocking the top block 26 with the sliding plate 21, the limit block 24 can always be clamped in the inside of the limit groove 15. If the sleeve body 14 needs to be removed, the sliding plate 21 can be moved and the sleeve body 14 can be pulled out from the inside of the rotating shaft 1.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
