Description

Technical Field

[0001] The utility model relates to a sweeping disc assembly of a sweeper which is convenient to replace. Background Art

[0002] Compared to manual cleaning, sanitation sweepers offer higher efficiency and better cleaning results. However, the sweeping disc assembly is the primary cleaning method and a vulnerable part of the vehicle. The sweeping disc assembly consists of a mounting disc connected to the motor power end and a cleaning brush at its base. Replacing the sweeping disc as a whole is costly, raising questions about its overall economic viability.

[0003] The purpose of the utility model is to provide a sweeping disc assembly for a sweeper that is easy to replace, so as to solve the related problems raised in the above background technology. Utility Model Content

[0005] Preferably, a Farah disc is fixedly connected to the upper end of the mounting rod, and the Farah disc is detachably connected to the outside world via a fastener.

[0006] Preferably, the rotating sleeve is rotatably connected to the bottom of the sleeve rod via a bearing, and a damping pad is further provided between the rotating sleeve and the sleeve rod.

[0007] Preferably, a reinforcing rib is provided between the plug-in rod and the brush plate, and an abutment plate abutting against the bottom of the mounting plate is fixedly sleeved on the outer side of the plug-in rod.

[0008] Preferably, the surface of the plug rod above the abutment plate is provided with a smooth surface and a threaded surface from top to bottom, the smooth surface above the plug rod is movable through the rotating sleeve, and the threaded surface above the plug rod is threadedly connected to the rotating sleeve.

[0009] Preferably, a guide groove is longitudinally provided on the surface of the plug rod above the abutment plate, and a guide block is fixedly connected to the inner wall of the sleeve rod near the bottom and is engaged with the guide groove. Beneficial effects

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] The utility model is achieved by splitting the sweeping disc and bristles of a traditional sweeper and arranging multiple groups of brush plates to integrate the bristles in various directions. On this basis, the brush plates are connected to the plug-in holes at the bottom of the mounting disc through plug-in rods, and are locked by rotating the rotating sleeve to cooperate with the threaded surface of the outer wall of the plug-in rod, so that the brush plates can be portablely disassembled and assembled. In an environment of long-term use, the severely worn brush plates can be directly disassembled and replaced without the need to disassemble and replace the entire sweeping disc assembly. The operation is simple and convenient, and the overall use cost is effectively saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0019] See also Figure 1-3 The utility model relates to a sweeping disc assembly of a sweeper which is easy to replace, comprising a mounting disc 1 and a brush plate 3 arranged at the bottom of the mounting disc 1. The bottom of the brush plate 3 is evenly provided with bristles 4 for cleaning the road surface. The upper end of the mounting disc 1 is fixedly connected to the mounting rod 2. A plurality of sleeve rods 5 are arranged above the mounting disc 1, which are connected to the upper end of the brush plate 3. The outer side of the sleeve rod 5 is fixedly connected to the mounting rod 2 through a reinforcing rod 6. The outer side of the lower end of the sleeve rod 5 is rotatably connected to a rotating sleeve 7. The rotating sleeve 7 is rotatably connected to the bottom of the sleeve rod 5 through a bearing 701. The mounting disc 1 is penetrated by a plug hole 8 which is connected to the bottom of the rotating sleeve 7. The upper end of the brush plate 3 is fixedly connected to a plug rod 9. The plug rod 9 movably passes through the plug hole 8 and the rotating sleeve 7. The movable sleeve 7 extends to the inner cavity of the sleeve rod 5, and a reinforcing rib 901 is provided between the plug-in rod 9 and the brush plate 3. The outer side of the plug-in rod 9 is also fixedly provided with an abutment plate 902 that abuts against the bottom of the mounting plate 1. The surface of the plug-in rod 9 above the abutment plate 902 is provided with a smooth surface 903 and a threaded surface 904 from top to bottom. The smooth surface 903 above the plug-in rod 9 is movable through the rotating sleeve 7, and the threaded surface 904 above the plug-in rod 9 is threadedly connected to the rotating sleeve 7. The surface of the plug-in rod 9 above the abutment plate 902 is also longitudinally provided with a guide groove 905, and the inner wall of the sleeve rod 5 near the bottom is fixedly connected with a guide block 906 that is clamped in the guide groove 905.

[0020] When the brush plate 3 is installed, the staff connects the plug-in rod 9 at the upper end of the brush plate 3 to the plug-in hole 8 at the bottom of the installation disk 1, and the guide groove 905 on the outside of the plug-in rod 9 connects the guide block 906 in the sleeve rod 5. (It should be noted that the guide block 906 can be installed on the inner wall of the plug-in hole 8 as needed.) When the plug-in rod 9 is close to the sleeve rod 5, the smooth surface 903 on the outside of the plug-in rod 9 passes through the rotating sleeve 7 and extends to the inner cavity of the sleeve rod 5. Then, the rotating sleeve 7 is adjusted to rotate and thread the threaded surface 904 on the outside of the plug-in rod 9. Due to the clamping limit between the guide groove 905 and the guide block 906, the rotating sleeve 7 drives the plug-in rod 9 to move up and down until the abutment plate 902 on the outside of the plug-in rod 9 abuts against the bottom of the installation disk 1, and the installation of the brush plate 3 is completed. The same is true for the subsequent disassembly of the brush plate 3. The operation is also very convenient, which increases the overall portability and reduces the replacement cost of the sweeping disc assembly.

[0021] Among them, the upper end of the mounting rod 2 is fixedly connected to a Farah disk 201, and the Farah disk 201 is detachably connected to the outside world through a fastener 202. The power end of the sweeper's cleaning motor is also fixedly connected to the Farah disk 201, and is fixedly connected to the Farah disk 201 at the upper end of the mounting rod 2 through a fastener 202, and the whole is to be installed in the sweeper for use.

[0022] Among them, a damping pad 702 is also provided between the rotating sleeve 7 and the sleeve rod 5. During the rotation of the rotating sleeve 7, the threaded surface 904 on the outside of the plug-in rod 9 can be threadedly driven. During this process, the damping pad 702 will produce some obstruction, so it needs to be rotated with a little force when used. However, during the overall operation, the damping pad 702 can also ensure the overall stability of use, and the rotating sleeve 7 will not become loose due to shaking, thereby ensuring the stability of the installation of the brush plate 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
