Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

As shown in fig. 1-3, the front side brush structure of a sweeper comprises a turntable 1, a first connecting member 2, a second connecting member 3, a brush component and a pressing component, wherein the turntable 1 is internally provided with a containing cavity 11, and the brush component and the pressing component are arranged below the bottom of the turntable 1. The turntable 1 is in transmission connection with a driving structure so as to drive the turntable 1 to rotate around the axis of the turntable 1. The side surface of the rotary table 1 is provided with a transverse groove 12 and a vertical groove 13 which are intersected and communicated. The transverse grooves 12 and the vertical grooves 13 are both communicated with the accommodating cavity 11. The lower edge of the transverse groove 12 is higher than the inner bottom wall of the accommodation chamber 11. The first connecting piece 2 is movably arranged in the accommodating cavity 11 and enters and exits the accommodating cavity 11 through the transverse groove 12. The first connector 2 is preferably a disc-shaped structure. Specifically, the first connecting member 2 is movably mounted in the accommodating chamber 11 up and down, and the outer peripheral surface thereof is in close fit connection with the inner wall of the accommodating chamber 11 located below the transverse groove 12. The bottom of the rotary table 1 is provided with an avoiding groove 14 communicated with the accommodating cavity 11. The escape grooves 14 are arranged extending in the front-rear direction. One end of the escape slot 14 forms an opening on the side of the turntable 1, the specific location of which opening is on the same side of the turntable 1 as the transverse slot 12. The lower end of the vertical groove 13 extends downward and intersects and communicates with the avoidance groove 14 at the opening. The second connecting piece 3 is movably arranged in the avoiding groove 14, the upper end of the second connecting piece 3 is connected with the first connecting piece 2, and the lower end of the second connecting piece 3 is connected with the bristle component. The pressing component is installed above the first connecting piece 2 and used for pressing the first connecting piece 2 downwards on the inner bottom wall of the accommodating cavity 11 or releasing the first connecting piece 2. Through the above structural design, the first connecting piece 2, the second connecting piece 3 and the bristle assembly form an integral structure, and when the first connecting piece 2 enters and exits the accommodating cavity 11 through the transverse groove 12, the second connecting piece 3 synchronously enters the bottom lower part of the rotary table 1 through the vertical groove 13 and the avoiding groove 14. The pressing component and the accommodating cavity 11 of the rotary disc 1 limit the first connecting piece 2, the first connecting piece 2 is fixed on the rotary disc 1, and then the brush hair component is also fixed on the rotary disc 1.

The second connecting part 3 is preferably a plate-shaped structure, the width of which corresponds to the width of the escape slot 14 and can limit the rotation of the first connecting part 2 in the accommodating cavity 11. The bristle sub-assembly comprises a disc 4 and bristles 41 distributed at the bottom of the disc, and the second connecting member 3 is connected with the disc 4. The second connecting member 3 may be connected to the disc 4 by welding, integral molding, or the like.

As shown in fig. 1, 3, 4 and 6, a threaded through hole 6 communicated with the accommodating cavity 11 is formed on the side surface of the rotary table 1. A plurality of threaded through holes 6 may be arranged at a position between the lower edge of the transverse groove 12 and the inner bottom wall of the accommodating chamber 11, and a set screw is screwed into the threaded through holes 6. The end of the set screw corresponds to the first connecting piece 2 mounted in the housing chamber 11. And screwing a set screw, wherein the end part of the set screw abuts against the first connecting piece 2, and the first connecting piece 2 is further fixed in the accommodating chamber 11, so that the fixing stability of the first connecting piece 2 is improved.

As shown in fig. 1, 2 and 3, the pressing assembly preferably comprises a plurality of bolts 5, the bolts 5 are screwed on the top of the rotating disk 1, and the lower ends of the bolts 5 extend into the accommodating cavities 11. Screwing the bolt 5, the lower end of the bolt 5 moves downwards, and the lower end of the bolt 5 abuts against the upper surface of the first connecting piece 2, so that the first connecting piece 2 is pressed tightly. The bolts 5 are turned in the opposite direction, and the first connecting member 2 can be loosened. In order to expand the operating space for screwing the bolt 5, the bolt 5 is arranged at the edge position close to the turntable 1. Of course, the pressing component can also be selected from spring pins, hydraulic rods and other structures.

When the brush is installed, the first connecting member 2, the second connecting member 3 and the brush assembly are previously installed together. The first connecting part 2 is aligned with the transverse slot 12, the second connecting part 3 is aligned with the vertical slot 13, the first connecting part 2 is inserted into the receiving cavity 11, and the second connecting part 3 moves into the avoiding slot 14. Then, the bristle assembly is pulled downwards to drive the first connecting member 2 to move downwards in the accommodating cavity 11, and the first connecting member 2 is tightly matched and connected with the inner wall of the accommodating cavity 11 below the transverse groove 12. Then, the bolt 5 is screwed, and the end of the bolt 5 abuts against the upper surface of the first connecting member 2 to press the first connecting member 2. Finally, the set screw is screwed, the end of which abuts against the side of the first connecting part 2. And when the device is disassembled, the same principle is reversed.

Due to the fact that the bolt 5 and the accommodating cavity 11 form good limiting for the first connecting piece 2, meanwhile, the second connecting piece 2 is located in the avoiding groove 13, and rotation of the first connecting piece 2 is also limited. By combining the above manners, the first connecting piece 2 is firmly fixed and cannot be loosened in the rotating process, and then the bristle component connected below the rotary table 1 cannot easily fall off. In addition, first connecting piece 2 and second connecting piece 3 can freely come in and go out from the side of carousel 1, and parts such as bolt 5 and holding screw are located the top surface or the side of carousel, need not wholly raise preceding brush, can dismantle the brush hair subassembly, have effectively improved the convenience of brush hair subassembly installation and dismantlement.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
