DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a spliced ​​rubber roller, comprising a rotating shaft 1, a rotating shaft sleeve 101 is sleeved on the side surface of the rotating shaft 1, and a plurality of positioning holes 103 are opened on the outer surface of the rotating shaft sleeve 101, a rubber roller ring 2 is sleeved on the outer side of the rotating shaft sleeve 101, and a positioning seat 4 is fixedly connected to the inner side surface of the rubber roller ring 2, and a positioning column 402 is slidably connected to the interior of the positioning seat 4, one end of the positioning column 402 is snapped into the interior of the positioning hole 103, and a side surface of the positioning seat 4 is opened. A strip-shaped through hole 403 is provided, and a horizontal plate 405 is slidingly provided inside the strip-shaped through hole 403. A rotating roller 404 is fixedly installed on one end of the horizontal plate 405, and the other end of the horizontal plate 405 is fixedly connected to the lower end side surface of the positioning column 402. A driving mechanism is provided on one side of the rotating roller 404, and a reset mechanism is provided on the other end of the positioning column 402. The outer surface of the rubber roller ring 2 is fixedly connected to the hard rubber layer 202, and the outer surface of the hard rubber layer 202 is fixedly connected to the rubber roller sleeve 201.

[0021] As a technical optimization solution of the present invention, the outer surface of the rotating shaft sleeve 101 is fixedly connected to the limiting plate 102, and the inner surface of the rubber roller ring 2 is provided with a limiting groove 204, and the limiting groove 204 corresponds to the limiting plate 102. The rubber roller ring 2 can be limited by the limiting plate 102 and the limiting groove 204 to prevent the rubber roller ring 2 from slipping relative to the rotating shaft 1.

[0022] As a technical optimization solution of the present invention, the driving mechanism includes a push plate 3, and a squeeze block 301 is fixedly connected to one side surface of the push plate 3, one end of the squeeze block 301 is provided with a slope, and one end of the squeeze block 301 is aligned with the rotating roller 404. By pushing the push plate 3 and the squeeze block 301, the rotating roller 404 can be squeezed, so that the positioning column 402 is retracted into the inside of the positioning seat 4, thereby making the positioning column 402 disengage from the positioning hole 103 to facilitate the movement and disassembly of the rubber roller ring 2.

[0023] As a technical optimization solution of the present invention, a sliding groove 303 is provided on the inner wall of the rubber roller ring 2, and a slide plate 302 is slidably connected to the inside of the sliding groove 303. One end of the slide plate 302 is fixedly connected to the push plate 3. The push plate 3 can be limited by the slide plate 302 and the sliding groove 303, thereby improving the sliding stability of the push plate 3.

[0024] As a technical optimization solution of the present invention, the reset mechanism includes a spring 401, and the upper end of the spring 401 is fixedly connected to the lower end of the positioning column 402, and the lower end of the spring 401 is fixedly connected to the inner wall of the positioning seat 4, which can push the positioning column 402 to return to its original position, so that the rubber roller ring 2 can be quickly positioned when installing it.

[0025] As a technical optimization solution of the present invention, one side surface of the rubber roller ring 2 is fixedly connected to the limiting rod 205, and the other side surface of the rubber roller ring 2 is provided with a limiting hole 203, and the limiting hole 203 is aligned with the limiting rod 205. Therefore, when installing the rubber roller ring 2, the adjacent rubber roller rings 2 can be plugged in through the limiting hole 203 and the limiting rod 205, thereby preventing the adjacent rubber roller rings 2 from separating.

[0026] When the present invention is in use, when the staff increases the length of the rubber roller according to the use requirements, first remove the rotating shaft 1 from the equipment, then take the increased rubber roller ring 2, and then align the limiting groove 204 on the inner surface of the rubber roller ring 2 with the limiting plate 102 on the outer surface of the rotating shaft sleeve 101. At the same time, the staff uses their fingers to push the push plate 3 inside the rubber roller ring 2. At this time, the push plate 3 will push the extrusion block 301 to squeeze the positioning column 402, and then the positioning column 402 will move downward along the inclined surface of one end of the extrusion block 301. At this time, the positioning column 402 drives 420 to retract into the interior of the positioning seat 4 through the cross plate 405. Then the staff pushes the rubber roller ring 2 It is sleeved on the outside of the rotating shaft sleeve 101 and slides along the limit plate 102. When the added rubber roller ring 2 is close to the rubber roller ring 2 originally installed on the outside of the rotating shaft sleeve 101, the limit rod 205 on the surface of one side of the added rubber roller ring 2 is inserted into the limit hole 203 on the other side surface of the originally installed rubber roller ring 2. At this time, the staff releases the push plate 3, so the positioning column 402 is pushed by the spring 401 in the reset mechanism to snap into the inside of the positioning hole 103, and then the installation is completed. When the rubber roller ring 2 needs to be removed, the staff only needs to push the push plate 3 to make the positioning column 402 retract to the inside of the positioning seat 4, and then the rubber roller ring 2 can be removed.
