DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all 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 belong to the scope of protection of the present utility model.

[0018] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0019] Refer to Figure 1 And Figure 2A switching mechanism of a detachable and installable rubber roller module as shown, which includes a slider 3 and a buckle groove 21. The slider 3 is arranged on the paper bin cover 1 and can reciprocate horizontally on the paper bin cover 1. A protruding buckle claw 31 is arranged at the upper end of the slider 3. An elastic member 4 is also arranged between the slider 3 and the paper bin cover 1. Under normal state, the elastic member 4 is compressed by force so that the elastic member 4 always exerts a force on the slider 3 to drive it to move horizontally relative to the paper bin cover 1. The buckle groove 21 is arranged at the lower end of the rubber roller bracket 2. The rubber roller is rotatably installed on the rubber roller bracket 2. When installing the rubber roller bracket 2, the rubber roller bracket 2 moves longitudinally horizontally relative to the paper bin cover 1 until the buckle claw 31 is buckled into the buckle groove 21, so as to fixedly install the rubber roller bracket 2 on the paper bin cover 1. When disassembling the rubber roller bracket 2, a person manually moves the slider 3 horizontally, and the buckle claw 31 moves with the slider 3 to disengage from the buckle groove 21, and the rubber roller bracket 2 can be quickly disassembled from the paper bin cover 1.

[0020] It should be noted that, in order to ensure the fixed connection between the rubber roller bracket 2 and the paper bin cover 1, a limiting protrusion is also arranged on one side of the rubber roller bracket 2 close to the paper bin cover 1, and a limiting groove 13 is correspondingly arranged on the paper bin cover 1. When the rubber roller bracket 2 is installed in place, the limiting protrusion is inserted into the limiting groove 13 to limit the horizontal and vertical movement of the rubber roller bracket 2 relative to the paper bin cover 1, and its cooperation with the buckle claw 31 and the buckle groove 21 structure ensures the fixed connection between the rubber roller bracket 2 and the paper bin cover 1.

[0021] In some possible embodiments, an installation part is arranged at one end of the slider 3, and an installation groove 11 for accommodating the button part 32 is arranged on the side surface of the paper bin cover 1. The depth of the installation groove 11 is greater than the thickness of the button part 32 to ensure that the button part 32 can drive the slider 3 to move horizontally.

[0022] In some possible embodiments, there are two buckle claws 31 which are spaced apart and arranged on the slider 3, and the purpose is to ensure the balance of the installation of the rubber roller bracket 2 on the paper bin cover 1.

[0023] In some possible embodiments, a receiving groove 33 is formed at the position on the slider 3 between the two buckle claws 31. A fixed stop block is arranged at the lower end of the paper bin cover 1, and the fixed stop block extends into the receiving groove 33. The elastic member 4 is located in the receiving groove 33 and one end of the elastic member 4 is pressed against the side wall of the receiving groove 33, and the other end is pressed against the fixed stop block, so that the elastic member 4 always exerts a force on the slider 3, and the slider 3 always has a tendency to move horizontally relative to the paper bin cover 1, that is, after the rubber roller bracket 2 is installed, the buckle claw 31 is always buckled into the buckle groove 21 to avoid the problem that the connection between the rubber roller bracket 2 and the paper bin cover 1 is unstable due to vibration.

[0024] In some possible embodiments, a perforation 14 through which the claw 31 can pass is formed in the paper bin cover 1. The claw 31 passes through the end face of the paper bin cover 1 and is snapped into the snap groove 21 to ensure the fixed connection between the rubber roller bracket 2 and the paper bin cover 1.

[0025] In some possible embodiments, an inclined guiding surface 34 is provided on the side of the claw 31 away from the center of the paper bin cover 1. When installing the rubber roller bracket 2, the side wall of the rubber roller bracket 2 / the edge of the snap groove 21 can press against the inclined guiding surface 34 to drive the slider 3 to move horizontally and laterally relative to the paper bin cover 1. The claw 31 moves with the slider 3 to yield to the rubber roller bracket 2. After the side wall of the rubber roller bracket 2 / the edge of the snap groove 21 passes over the claw 31, the elastic restoring force of the elastic member 4 acts to drive the claw 31 / the slider 3 to reset, and the claw 31 is automatically snapped into the snap groove 21, thereby fixing the rubber roller bracket 2. It can be seen that such a design can facilitate the installation of the rubber roller bracket 2 onto the paper bin cover 1.

[0026] In some possible embodiments, a guiding strip 12 along the horizontal longitudinal direction is provided on the paper bin cover 1, and a guiding groove 22 is correspondingly provided on the rubber roller bracket 2. The cross section of the guiding strip 12 is wedge-shaped, and the cross section of the guiding groove 22 is also correspondingly set to be wedge-shaped. In this embodiment, the cooperation between the guiding strip 12 and the guiding groove 22 can accurately install the rubber roller bracket 2 on the paper bin cover 1.

[0027] As described above, only the specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
