A clamping groove adapted to the clamping block is provided on the connecting platform. An inclined block is fixedly connected to the bottom of the clamping block. An inclined block slidably connected to the frame is fixedly connected to the clamping block. By setting the clamping mechanism, the installation of the brush can be quickly completed, the assembly speed of the square brush is improved, and the installation difficulty of the brush for the staff is reduced.

[0004] When this application is in use, the square brush is mainly quickly replaced and installed through the clamping mechanism. However, the clamping mechanism used in this application has a relatively complex structure, and the rotating rod needs to be manipulated for a long time during disassembly and assembly, thus affecting the installation efficiency of the square brush. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the purpose of the present utility model is to provide a square brush for a sweeper that is easy to disassemble, so as to solve the technical problems mentioned in the above background technique.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A square brush for a sweeper that is easy to disassemble, includes a cleaning disc. A number of installation grooves are provided on the outer peripheral side of the cleaning disc. The installation grooves are arranged in a circular array. An upper positioning shaft and a lower positioning shaft are fixedly connected in the installation groove. A brush block member is arranged in the installation groove;

[0008] The brush block includes an upper positioning block, a lower positioning block and bristles. The upper positioning block is U-shaped and is rotatably mounted on the upper positioning shaft. The lower positioning block is J-shaped and is snap-fitted on the lower positioning shaft. The bristles are fixedly connected to the bottom side of the lower positioning block.

The springs are arranged outside the corresponding limiting shafts, and the upper and lower ends of the springs are respectively fixedly connected to the bottom side of the upper positioning block and the top side of the lower positioning block.

[0010] In a preferred example of the present utility model, it can be further configured that: there is a gap between the top side of the upper positioning block and the top side wall of the installation groove.

[0011] In a preferred example of the present utility model, it can be further configured that: the bottom of the installation groove is open, and the lower positioning block is slidably connected to the installation groove.

[0012] In a preferred example of the present utility model, it can be further configured that: there is a gap between the top end of the limiting shaft and the top side wall of the upper insertion hole, and there is a gap between the bottom end of the limiting shaft and the bottom side wall of the lower insertion hole.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] 1. For the easily detachable square brush for a road sweeper, during use, the upper positioning block can be directly snapped onto the upper positioning shaft, then the lower positioning block is pulled down, and then the lower positioning block is snapped onto the lower positioning shaft. This square brush has a simple structure, rapid installation and disassembly, achieving the effects of simple steps and reduced operation time, and at the same time ensuring the stability after installation, avoiding the effect of detaching from the cleaning disk under high-speed rotation.

[0015] 2. For the easily detachable square brush for a road sweeper, the gap between the top side of the upper positioning block and the installation groove enables the upper positioning block to tilt outwards when inserted into the installation groove, causing the lower positioning block to move away from the lower positioning shaft, so that the upper positioning block is inserted into the installation groove obliquely, and then rotatably connected to the upper positioning shaft. After the upper positioning block is rotatably connected to the upper positioning shaft, it is convenient for the lower positioning block to be pulled down and snapped onto the lower positioning shaft.

[0016] 3. The detachable square brush for a road sweeper has an open bottom of the installation groove. After the lower positioning block is pulled down, the positioning block rotates to the bottom opening of the installation groove. Subsequently, the side of the lower positioning block close to the inner wall of the installation groove will slide upward along the inner wall of the installation groove, so that the bent part of the lower positioning block is clamped on the lower positioning shaft.

[0017] 4. For the detachable square brush for a road sweeper, there is a gap between the top end of the limiting shaft and the top side wall of the upper jack, and a gap between the bottom end of the limiting shaft and the bottom side wall of the lower jack. When the lower positioning block is pulled down, while not affecting the limiting of the spring by the limiting shaft, it provides a certain space for the movement of the lower positioning block, preventing the limiting shaft from disengaging from the upper jack and the lower jack after the lower positioning block is pulled down, which may cause the spring to lose its limitation and easily lead to bending deformation of the spring, affecting the installation of the square brush.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described in detail below with reference to the drawings.

[0024] Embodiment:

[0025] Refer to Figures 1-3The utility model discloses a detachable block brush for a sweeper, comprising a sweeping disc 1, a plurality of mounting grooves 2 are provided on the outer peripheral side of the sweeping disc 1, the mounting grooves 2 are arranged in a circular array, an upper positioning shaft 3 and a lower positioning shaft 4 are fixedly connected in the mounting groove 2, and a brush block 5 is arranged in the mounting groove 2;

[0026] The brush block 5 includes an upper positioning block 6, a lower positioning block 7 and bristles 8. The upper positioning block 6 is U-shaped and rotatably mounted on the upper positioning shaft 3. The lower positioning block 7 is J-shaped and is clamped on the lower positioning shaft 4. The bristles 8 are fixedly connected to the bottom side of the lower positioning block 7. The upper positioning block 6 and the lower positioning block 7 are connected by a limiting member 9.

[0027] After the brush 8 is installed, the upper positioning block 6 is first clamped on the upper positioning shaft 3, and then the lower positioning block 7 is pulled down to increase the spacing between the lower positioning block 7 and the upper positioning block 6, and then the bending part of the lower positioning block 7 passes over the lower positioning shaft 4, and then the upper positioning shaft 3 is used as the axis to rotate the upper positioning block 6 on the upper positioning shaft 3 so that the lower positioning block 7 approaches the lower positioning shaft 4 until the inner side wall of the lower positioning block 7 contacts the lower positioning shaft 4, and then the lower positioning block 7 is released so that the spacing between the upper positioning block 6 and the lower positioning block 7 is reduced through the limiting member 9, so that the bending part of the lower positioning block 7 is clamped on the lower positioning shaft 4, thereby achieving the effect of limiting the upper positioning block 6 and the lower positioning block 7, and then achieving the effect of quickly installing the square brush. When removing the bristles 8, the lower positioning block 7 is pulled down and rotated at this time, so that the lower positioning shaft 4 is separated from the retraction path of the lower positioning block 7, and then the lower positioning block 7 is released, and the upper positioning block 6 can be directly pulled out.

[0028] In a further preferred embodiment of the present invention, Figures 1-3 As shown, the limiting member 9 includes two limiting shafts 10 and two springs 11, the bottom side of the upper positioning block 6 is provided with two upper plug holes 12, and the top side of the lower positioning block 7 is provided with two lower plug holes 13, the two limiting shafts 10 are respectively inserted into the corresponding upper plug holes 12, and the bottom ends of the limiting shafts 10 extend into the corresponding lower plug holes 13, and the springs 11 are arranged on the corresponding outer sides of the limiting shafts 10, and the upper and lower ends of the springs 11 are respectively fixedly connected to the bottom side of the upper positioning block 6 and the top side of the lower positioning block 7.

[0029] In this embodiment, when the lower positioning block 7 is pulled, the provided limiting shaft 10 will slide within the upper insertion hole 12 and the lower insertion hole 13, and at the same time, two springs 11 will be stretched. After the lower positioning block 7 is clamped onto the lower positioning shaft 4, the lower positioning block 7 is then released. Subsequently, the reaction force of the spring 11 will pull the lower positioning block 7 in the direction of the upper positioning block 6. At the same time, the limiting shaft 10 will continue to be within the corresponding upper insertion hole 12 and lower insertion hole 13 to limit the spring 11, preventing the spring 11 from bending and tilting during stretching and retraction, which may affect the limitation of the lower positioning block 7. Subsequently, the bent portion of the lower positioning block 7 will be clamped onto the lower positioning shaft 4, preventing the square brush from falling off due to external shaking and improving the stability.

[0030] In a further preferred embodiment of the present utility model, as Figure 2 shown, there is a gap between the top side of the upper positioning block 6 and the top side wall of the installation groove 2.

[0031] In this embodiment, a gap is provided between the upper positioning block 6 and the top side wall of the installation groove 2. When the upper positioning block 6 is inserted into the installation groove 2 and positioned and connected to the upper positioning shaft 3, at this time, the lower positioning block 7 will be blocked by the lower positioning shaft 4, resulting in the upper positioning block 6 being unable to be normally inserted into the installation groove 2. At this time, the gap between the top side of the upper positioning block 6 and the installation groove 2 allows the upper positioning block 6 to tilt outward when inserted into the installation groove 2, causing the lower positioning block 7 to move away from the lower positioning shaft 4. Thus, the upper positioning block 6 can be tilted and inserted into the installation groove 2, and then rotatably connected to the upper positioning shaft 3. After the upper positioning block 6 is rotatably connected to the upper positioning shaft 3, it is convenient for the lower positioning block 7 to be pulled down and clamped onto the lower positioning shaft 4.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-2 shown, the bottom of the installation groove 2 is open, and the lower positioning block 7 is slidably connected to the installation groove 2.

[0033] In this embodiment, the bottom of the installation groove 2 is open, such that after the lower positioning block 7 is pulled down, the positioning block rotates to the bottom opening of the installation groove 2. Subsequently, the side of the lower positioning block 7 close to the side wall of the installation groove 2 will slide upward along the inner side wall of the installation groove 2, thereby clamping the bent portion of the lower positioning block 7 onto the lower positioning shaft 4.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, there is a gap between the top end of the limiting shaft 10 and the top side wall of the upper insertion hole 12, and there is a gap between the bottom end of the limiting shaft 10 and the bottom side wall of the lower insertion hole 13.

[0035] In this embodiment, a gap is left between the top end of the limiting shaft 10 and the top side wall of the upper jack 12, and a gap is left between the bottom end of the limiting shaft 10 and the bottom side wall of the lower jack 13. When the lower positioning block 7 is pulled down, while not affecting the limiting of the spring 11 by the limiting shaft 10, a certain space is provided for the movement of the lower positioning block 7, avoiding the separation of the limiting shaft 10 from the upper jack 12 and the lower jack 13 after the lower positioning block 7 is pulled down, which may cause the spring 11 to lose its limitation and thus easily lead to bending deformation of the spring 11, affecting the installation of the square brush.

[0036] The embodiments of this specific implementation mode are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
