Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-5, the present invention relates to a swimming pool cleaning brush, which comprises a handle 100, a rotating head 110, a brush plate 200, a limiting component 300 and a limiting bolt 320.

One end of the handle 100 is provided with the rotary head 110, the brush board 200 is arranged on the rotary head 110, the brush board 200 can rotate relative to the rotary head 110, the rotary head 110 is internally provided with a limiting component 300 for limiting the rotation of the brush board 200 relative to the rotary head 110, a spring 310 is arranged between the limiting component 300 and the rotary head 110, the limiting component 300 is connected with the brush board 200 through a limiting bolt 320, and the limiting bolt movably penetrates through the brush board, when people need to rotate the brush board 200 relative to the handle 100 and the rotary head 110, people only need to press the limiting component 300, as the limiting component 300 is in threaded connection with the limiting bolt 320, the limiting bolt 320 also synchronously moves along with the limiting component 300, so that the limiting bolt 320 no longer limits the rotation of the brush board 200 relative to the rotary head 110, meanwhile, the spring 310 is stressed and compressed, therefore, people can actually need to rotate the brush board 200, when the brush board 200 rotates to a preset angle relative to the rotary head 110, the acting force on the limiting, at this time, the limiting member 300 is subjected to the elastic force of the spring 310, and the limiting member 300 and the limiting bolt 320 are simultaneously reset, so that the brush plate 200 is not rotated relative to the rotating head 110 any more, and thus, the swimming pool cleaning brush can clean the corners of the swimming pool.

The limiting component 300 comprises a movable column 330 movably inserted in the rotary head 110, one end of the movable column 330 is provided with a through column 340, the other end of the movable column 330 is provided with a pressing column 350, the diameter of the movable column 330 is larger than that of the through column 340, the diameter of the pressing column 350 is larger than that of the movable column 330, the through column 340 is connected with a limiting bolt 320, a pressing hole 111 for inserting the pressing column 350 is arranged in the rotary head 110, an inner sleeve 112 arranged in an inverted manner is arranged in the rotary head 110, a movable hole 113 for inserting the through column 340 is arranged in the inner sleeve 112, the pressing hole 111 is communicated with the movable hole 113, a spring 310 is sleeved on the through column 340, one end of the spring 310 abuts against the movable column 330, the other end of the spring 310 abuts against the bottom of the inner sleeve 112, a through hole 220 corresponding to the through column is arranged on the brushing plate 200, an annular groove 114 is arranged between the rotary head 110 and the inner sleeve 112, a plurality of upper clamping plates 115 are arranged in the annular array around the central axis of, the outer side of the convex ring 210 is provided with a lower clamping plate 211 corresponding to the upper clamping plate 115 in an annular array around the central axis thereof, and the through holes 220 are communicated with the convex ring 210.

When a person presses the pressing column 350, the through column 340 is fixedly connected with the movable column 330, the movable column 330 is fixedly connected with the pressing column 350, the limiting bolt 320 is in threaded connection with the through column 340, so that the pressing column 350 moves downwards relative to the pressing hole 111, the movable column 330 moves downwards relative to the movable hole 113, the through column 340 moves downwards relative to the movable hole 113 and the through hole 220, the limiting bolt 320 no longer blocks the brush plate 200, the brush plate 200 moves downwards relative to the rotary head 110, the convex ring 210 is separated from the annular groove 114, therefore, the lower clamping plate 211 is separated from between the two corresponding upper clamping plates 115, the convex ring 210 can rotate along the central axis of the convex ring 210 due to the fact that the convex ring 210 is fixedly connected with the brush plate 200, the brush plate 200 also rotates along the central axis of the convex ring 210, and meanwhile, the spring 310 is stressed and compressed; when the rotation angle of the brush plate 200 relative to the rotor 110 meets the actual requirement of people, the acting force acting on the pressing column 350 is removed, so that the limiting assembly 300 at this moment automatically resets through the spring 310, specifically, the spring 310 pushes the pressing column 350, the movable column 330, the penetrating column 340 and the limiting bolt 320 to move upwards relative to the rotor 110, so that the limiting bolt 320 drives the brush plate 200 to move upwards until the convex ring 210 is inserted into the groove again, and the lower clamping plate 211 is clamped between the two corresponding upper clamping plates 115, and because the upper clamping plates 115 are fixedly connected with the rotor 110, the lower clamping plates 211 are fixedly connected with the convex ring 210, so that the upper clamping plates 115 block the convex ring 210 from rotating, that is, the convex ring 210 cannot rotate relative to the rotor 110, that is, the brush plate 200 cannot rotate relative to the rotor 110 any more.

At least one end setting of brush board 200 is the arc of 90 degrees, is equipped with a plurality of brush hairs 230 on the bottom surface of brush board 200, through the setting of this mechanism for the wall corner of clean swimming pool, the waterline of clean wall and swimming pool step etc. that this brush board 200 can be better.

The utility model discloses in, can cup joint handle cover (not marking in the figure) on the side of handle 100 and use as the hand brush, perhaps connect the extension rod (not marking in the figure) that is applicable to this handle on the handle and use, specifically, can adopt threaded connection between handle 100 and the extension rod (not marking in the figure).

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
