A linkage structure is connected in between, and two end plates are sleeved on the roller shaft, which are respectively installed at both ends of the base tube. The end plates are slidably installed with multiple strip drive plates corresponding to the linkage structure along the circumferential direction, and the strip drive plates are attached to the outer side of the roller shaft. The brush roller structure has a working mode and a disassembly mode. When the brush roller structure is in the working mode, the movable connecting part cooperates with the fixed connecting part to make the corresponding arc-shaped brush plate close to the base tube; when the brush roller structure is switched to the disassembly mode, the sliding strip drive plate drives the corresponding linkage structure to link the two axially opposite movable connecting parts to move synchronously and separate from the corresponding fixed connecting parts, so that the corresponding arc-shaped brush plate can be removed from the base tube; at this time, it is only necessary to pull the strip plug-in part out of the strip plug-in hole to make the corresponding arc-shaped brush plate can be removed from the base tube.

DETAILED DESCRIPTION

[0027] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Figures 1 to 8 As shown, the present invention provides a brush roller structure with an insert-type convenient brush strip replacement, comprising a roller shaft 1, a base tube 2 installed coaxially with the roller shaft 1, an outer wall of the base tube 2 is evenly distributed along the axial direction with a plurality of arc-shaped brush plates 3 with brush strips 32 arranged thereon, an inner wall of the arc-shaped brush plate 3 is provided with a strip-shaped inserting portion 31, a plurality of strip-shaped inserting holes 21 are evenly distributed along the circumferential direction on the outer side of the arc-shaped brush plate 3, the strip-shaped inserting portions 31 are correspondingly inserted into the strip-shaped inserting holes 21, so that the arc-shaped brush plate 3 remains fixed in the axial direction. A connecting assembly is provided between the two ends of the strip plug-in portion 31 and the outer side of the roller shaft 1, and the connecting assembly includes a fixed connecting piece arranged on the strip plug-in portion 31 and located in the base tube 2, and a movable connecting piece arranged on the outer side of the roller shaft 1 and corresponding to the fixed connecting piece; a linkage structure is connected between every two movable connecting pieces that are opposite to each other axially along the roller shaft 1, and two end plates 4 are respectively installed on the roller shaft 1 at both ends, and a plurality of strip driving plates 6 corresponding to the linkage structure are installed on the end plates 4 in a circumferentially sliding manner, and the strip driving plates 6 are attached to the outer side surface of the roller shaft 1. The brush roller structure has a working mode and a disassembly mode. When the brush roller structure is in the working mode, the movable connecting part cooperates with the fixed connecting part to make the corresponding arc-shaped brush plate 3 close to the base tube 2. At this time, the brush roller structure can grind the steel plate normally; when the brush roller structure switches to the disassembly mode, the sliding strip drive plate 6 drives the corresponding linkage structure to link the two axially opposite movable connecting parts to move synchronously and separate from the corresponding fixed connecting parts, so that the corresponding arc-shaped brush plate 3 can be removed from the base tube 2. At this time, you only need to pull the strip plug-in part 31 out of the strip plug-in hole 21 to make the corresponding arc-shaped brush plate 3 removable from the base tube 2.

[0029] Further, in this embodiment, the connecting component is a hook-type component. Specifically, the fixed connecting part is a fixed hook 311 arranged on the strip-shaped plug-in portion 31, and the movable connecting part is a plurality of movable hooks 11 evenly distributed along the circumferential direction on the roller shaft 1; specifically, a plurality of column pairs 13 are evenly distributed along the circumferential direction on the roller shaft 1, and the corresponding movable hook 11 is rotatably installed between the two columns of the column pair 13, and the column pair 13 provides a carrier for the rotatable installation of the movable hook 11; the movable hook 11 can swing on the roller shaft 1 and disengage from the fixed hook 311, so that the corresponding arc-shaped brush plate 3 can be separated from the base pipe 2. When the brush roller structure is in working mode, the movable hook 11 and the fixed hook 311 are interlocked so that the corresponding arc-shaped brush plate 3 is tightly attached to the base tube 2; when the brush roller structure is switched to disassembly mode, the strip drive plate 6 slides axially along the roller shaft 1 and drives the corresponding linkage structure to link the two axially opposite movable hooks 11 to swing synchronously and separate from the corresponding fixed hooks 311, so that the corresponding arc-shaped brush plate 3 can be removed from the base tube 2.

[0030] Furthermore, the linkage structure needs to simultaneously link the movable hook 11 to swing synchronously, so as to achieve the cooperation or separation with the fixed hook 311. The linkage structure is an elastic V-shaped rod 5 connected between two axially opposite movable hooks 11. The strip drive plate 6 slides toward the inside of the base tube 2, presses and causes the elastic V-shaped rod 5 to deform, so as to link the two axially opposite movable hooks 11 to swing synchronously. When subjected to the pressure of the strip drive plate 6, the elastic V-shaped rod 5 can convert its own elastic force into a linkage force to act on the movable hook 52 to act on the movable hook 11. When the strip drive plate 6 separates from the elastic V-shaped rod 5, the elastic V-shaped rod 5 can quickly reset, so that the movable hook 11 cooperates with the fixed hook 311 on the new arc brush plate 3 to prevent the arc brush plate 3 from detaching.

[0031] Furthermore, the strip drive plate 6 includes arms connected to two axially opposite movable hooks 11 respectively. In order to enable the two axially opposite movable hooks 11 to synchronously disengage from the fixed hooks 311, the two movable hooks 11 should be subjected to the same linkage force so as to produce the same swing amplitude. Therefore, in this embodiment, the junction of the strip drive plate 6 and the two arms corresponds to each other; the strip drive plate 6 presses the junction of the two arms on the elastic V-shaped rod 5 and causes the elastic V-shaped rod 5 to deform so as to link the two axially opposite movable hooks 11 to swing synchronously; the strip drive plate 6 can cause the two arms to produce the same amplitude of deformation, so that each two axially opposite movable hooks 11 can stably disengage from the corresponding fixed hooks 311.

[0032] Furthermore, in order to enable the movable hook 11 to be quickly reset, the brush roller structure also includes an elastic member, which acts on the movable hook 11. When the strip drive plate 6 acts on the corresponding linkage structure, the movable hook 11 swings and causes the elastic member to deform. When the strip drive plate 6 is separated from the linkage structure, the elastic member releases the elastic force and causes the movable hook 11 to reset. The elastic member can provide a reset elastic force for the movable hook 11, so that when the brush roller structure is in the working mode, the movable hook 11 can form a buckle fit with the fixed hook 311. Specifically, the movable hook 11 is rotatably connected to the column pair 13 through a rotating shaft, and the elastic member is a torsion spring 12 that is sleeved on the rotating shaft and acts on the movable hook 11. The torsion spring 12 can provide sufficient reset elastic force for the movable hook 11, and at the same time, it occupies a small space and is easy to arrange.

[0033] Further, in order to ensure that the end plate 4 is stably installed at the two ends of the base tube 2, the inner and outer sides of the end plate 4 are respectively connected to the inner ring plate 41 and the outer ring plate 42 in one piece; the inner ring plate 41 is sleeved on the outer side of the roller shaft 1; the outer ring plate 42 is coaxially installed on the inner side of the base tube 2; the inner ring plate 41 is fixedly installed on the outer side of the roller shaft 1 by screws, and the outer ring plate 42 is fixedly installed on the inner side of the base tube 2 by screws. Specifically, the end plate 4 is evenly distributed along the circumferential ring to form limiting holes 43 that penetrate the inner ring plate 41; the limiting holes 43 correspond to the column pairs 13 one by one, and the width of the limiting holes 43 is smaller than the spacing between the two columns of the column pair 13, so as to ensure that the strip drive plate 6 can slide smoothly along the axial direction of the roller shaft 1, thereby driving the elastic V-shaped rod 5 to deform; the strip drive plate 6 passes through the corresponding strip drive plate 6 and the two columns of the column pair 13 in sequence. More specifically, the cross-section of the strip driving plate 6 is arc-shaped, so that the inner side of the strip driving plate 6 matches the outer side of the roller shaft 1; in order to enable the strip driving plate 6 to smoothly extend into the junction of the two arms of the elastic V-shaped rod 5, a wedge-shaped surface 61 is provided on the outer side of one end of the strip driving plate 6, so that the insertion of the strip driving plate 6 is convenient and smooth; a plurality of magnets are embedded in the inner side surface of the strip driving plate 6; a plurality of magnets are provided to ensure that when the strip driving plate 6 is not driving, the strip driving plate 6 can be stably adsorbed on the outer side of the roller shaft 1, that is, to ensure stable placement when idle.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
