When the rolling roller body 1 and the rolling shaft body 2 are installed using the threaded rod 3, the device sets a positioning column 35 to limit the rotating plate 31 on the threaded rod 3, so as to avoid the threaded rod 3 from becoming loose and affecting the use of the rolling roller body 1 when the rolling shaft body 2 and the rolling roller body 1 are in use. The positioning column 35 is inserted into the positioning groove 24 to limit the threaded rod 3, thereby preventing the threaded rod 3 from rotating loose.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution in the embodiment of the present application is to effectively solve the technical problem that when the roller body 1 and the roller shaft body 2 are used to roll the metal plate, the threaded rod 3 may become loose, which may cause the roller body 1 and the roller shaft body 2 to be not fixed tightly, affecting the use effect of the roller body 1. The overall idea is as follows: a connecting structure of a roller and a roller shaft, including a roller body 1 and a roller shaft body 2, the roller body 1 and the roller shaft body 2 are provided with a fixing mechanism for facilitating the connection between the roller body 1 and the roller shaft body 2, the fixing mechanism includes a first fixing plate 11, a second fixing plate 22 and a threaded Rod 3, the number of first fixed disks 11 is two, and the two first fixed disks 11 are fixedly installed on the circumferential end of the roller body 1, the number of roller shaft bodies 2 is two, and the two roller shaft bodies 2 are respectively located at the two side ends of the roller body 1, and the circumferential ends of the two roller shaft bodies 2 are fixedly installed with second fixed disks 22, and the user can insert the roller shaft body 2 into the inner side wall of the roller body 1 when installing between the two roller shaft bodies 2 and the roller body 1, and when the second fixed disk 22 approaches the first fixed disk 11, the threaded rod 3 on the second fixed disk 22 will approach the thread groove 12;

[0023] The side ends of the two second fixed disks 22 are penetrated with mounting grooves 23, the number of threaded rods 3 is at least two, each threaded rod 3 is rotatably mounted on the inner side wall of the mounting groove 23, the side ends of the two first fixed disks 11 are penetrated with two threaded grooves 12, the side ends of the two first fixed disks 11 are also penetrated with two limiting grooves 13, the side ends of the two roller shaft bodies 2 are fixedly mounted with limiting shafts 21, the two limiting shafts 21 are slidably mounted on the inner side walls of the two limiting grooves 13, the side ends of the two roller shaft bodies 2 and the outer sides of the mounting grooves 23 are penetrated with at least two positioning grooves 24, each threaded rod 3 is threadedly rotatably mounted on the inner side wall of the threaded groove 12, the user can turn the threaded rod 3 to make the threaded rod 3 enter the threaded groove 12, fix and tighten the second fixed disk 22 on the roller shaft body 2 and the first fixed disk 11 on the roller body 1, after the second fixed disk 22 and the first fixed disk 11 are fixed and tightened;

[0024] A rotating plate 31 is fixedly installed on the side end of each threaded rod 3, and a cylindrical groove 32 is penetrated through the side end of each rotating plate 31, and an L-shaped fixing plate 33 is fixedly installed on the side end of each rotating plate 31, and a magnetic block 34 is fixedly installed on the side end of each L-shaped fixing plate 33, and a positioning column 35 is slidably installed on the inner side wall of each cylindrical groove 32, and a pull plate 37 is fixedly installed on the side end of each positioning column 35, and two springs 36 are fixedly installed between each pull plate 37 and the rotating plate 31. When the threaded rod 3 approaches the threaded groove 12, the user can pull the pull plate 37 to move, and the movement of the pull plate 37 drives the positioning column 35 to move. When the positioning column 35 moves away from the inner side wall of the positioning groove 24, the spring 36 is stretched, and the pull plate 37 will be adsorbed by the magnetic block 34, and the threaded rod 3 is no longer limited.

[0025] In view of the problems existing in the prior art, the utility model provides a connection structure between a rolling roller and a rolling shaft. The device cooperates with a positioning column 35, a positioning groove 24 and a threaded rod 3. When the threaded rod 3 is used to install the rolling roller body 1 and the rolling shaft body 2, the device limits the rotating plate 31 on the threaded rod 3 by setting the positioning column 35, so as to prevent the threaded rod 3 from generating loose threads and affecting the use of the rolling roller body 1 when the rolling shaft body 2 and the rolling roller body 1 are in use. The positioning column 35 is inserted into the positioning groove 24 to limit the threaded rod 3, thereby preventing the threaded rod 3 from rotating loose threads.

[0026] Working principle:

[0027] When installing between the two roller shaft bodies 2 and the roller body 1, the user can insert the roller shaft body 2 into the inner side wall of the roller body 1. When the second fixed plate 22 approaches the first fixed plate 11, the threaded rod 3 on the second fixed plate 22 will approach the thread groove 12. When the threaded rod 3 approaches the thread groove 12, the user can pull the pull plate 37 to move, and the movement of the pull plate 37 drives the positioning column 35 to move. When the positioning column 35 moves away from the inner side wall of the positioning groove 24, the spring 36 is stretched, and the pull plate 37 is attracted to the magnetic block 34. At this time, the threaded rod 3 is no longer limited. The user can turn the threaded rod 3 so that the threaded rod 3 enters the threaded groove 12, and fixes and tightens the second fixed plate 22 on the roller shaft body 2 and the first fixed plate 11 on the roller body 1. After the second fixed plate 22 and the first fixed plate 11 are fixed and tightened, the user can stop rotating the threaded rod 3 and push the pull plate 37. When the pull plate 37 moves and is no longer attracted to the magnetic block 34, the spring 36 no longer receives the tension and rebounds. The spring 36 rebounds and drives the pull plate 37 to move. The movement of the pull plate 37 drives the positioning column 35 to enter the positioning groove 24 again to limit the rotating plate 31. At this time, the threaded rod 3 The rod 3 is limited, and the limiting shaft 21 on the roller shaft body 2 enters the limiting groove 13, completing the installation of the roller body 1 and the roller shaft body 2. In the existing installation of the roller body 1 and the roller shaft body 2, the threaded rod 3 is mostly used for fixing. However, when the roller body 1 and the roller shaft body 2 are used to roll the metal plate, the threaded rod 3 may become loose, which may cause the roller body 1 and the roller shaft body 2 to be not fixed tightly, affecting the use effect of the roller body 1. The device is provided with a positioning column 35, a positioning groove 24 and a threaded rod 3. When the threaded rod 3 is used, the positioning column 35, the positioning groove 24 and the threaded rod 3 are matched. When installing the roller body 1 and the roller shaft body 2, the device sets a positioning column 35 to limit the rotating plate 31 on the threaded rod 3 to prevent the threaded rod 3 from affecting the use of the roller body 1 when the roller shaft body 2 and the roller body 1 are in use. The positioning column 35 is inserted into the positioning groove 24 to limit the threaded rod 3, thereby preventing the threaded rod 3 from rotating freely. In addition, the device sets a limiting shaft 21 and a limiting groove 13 to cooperate. The limiting shaft 21 is inserted into the roller body 1 to further limit and fix it, thereby increasing the stability between the roller shaft body 2 and the roller body 1.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
