Description

Technical Field

[0001] The invention relates to the technical field of vacuum brushes, and more specifically to a vacuum brush supporting structure. Background Art

[0002] The vacuum brush is usually installed at the end of the vacuum tube of the vacuum cleaner, and the user pushes the vacuum brush to move back and forth on the ground to sweep up the garbage and dust on the ground so that they can be sucked in by the vacuum cleaner. In order to make it easier for the user to push, a roller is usually installed on the support structure of the vacuum brush.

[0003] However, the existing vacuum brush support structure usually installs rollers at both ends and outside the vacuum brush, so that when cleaning corners, the rollers will block the vacuum brush, making it difficult for the vacuum brush to clean the corners.

[0004] Therefore, it is necessary to provide a vacuum brush supporting structure to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a vacuum brush support structure to facilitate cleaning of corners.

[0006] The technical solution adopted by the present application to solve its technical problem is: a vacuum brush support structure, including a support plate, vacuum brushes are fixed on both sides below the support plate, an access pipe is fixed in the middle of the upper side of the support plate, the access pipe is connected to the lower side of the support plate, and a plurality of rollers are arranged on the lower side of the support plate, and the rollers are all located on the inner sides of two vacuum brushes.

[0007] Furthermore, both ends of the support plate are provided with mounting openings, mounting plates are fixedly mounted at the mounting openings, and the rollers are mounted on the lower side of the mounting plates.

[0008] Furthermore, a plurality of first through holes are distributed on the edge of the mounting port, a plurality of second through holes corresponding to the positions of the first through holes are arranged on the edge of the mounting plate, screws are arranged on the upper sides of the second through holes, and one end of the screw passes through the second through hole and the first through hole and is threadedly connected with a nut.

[0009] Furthermore, a shaft sleeve is fixed on the mounting plate, a lifting shaft is arranged in the shaft sleeve, the lower end of the lifting shaft passes through the shaft sleeve, the mounting plate and the mounting port and is fixed with the lifting plate, the roller is rotatably connected to the lower side of the lifting plate, an elastic part is arranged between the lifting plate and the mounting plate, and the upper end of the lifting shaft extends out of the upper end of the shaft sleeve and is threadedly connected with a threaded sleeve.

[0010] Furthermore, a handle is provided on the upper edge of the threaded sleeve.

[0011] Furthermore, a slot is provided on one side of the lifting shaft, and a block corresponding to the slot is provided inside the shaft sleeve.

[0012] The beneficial effects of the utility model are:

[0013] Since the roller is located on the inner side of the two vacuum brushes, when cleaning corners, the roller will not block the vacuum brushes, allowing the vacuum brushes to reach and clean the corners;

[0014] The elastic part will push the support plate upward through the mounting plate due to its own elasticity. At this time, the threaded sleeve will hold the top of the shaft sleeve, thus limiting the height of the support plate. With the threaded sleeve moving up and down on the lifting shaft, the height of the support plate can be controlled to avoid the problem that the support plate is too low, causing the dust brush to rub against the bottom surface too much and be damaged too quickly, or the support plate is too high, causing the dust brush to be unable to sweep up the garbage.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0026] like Figure 1-3 As shown, the present application provides a dust brush support structure, including a support plate 1, dust brushes 11 are fixed on both sides below the support plate 1, and an access pipe 12 is fixed in the middle of the upper side of the support plate 1, and the access pipe 12 is connected to the lower side of the support plate 1. It can be understood that the access pipe 12 is used to connect to the dust pipe of an external vacuum cleaner (not shown).

[0027] Both ends of the support plate 1 are provided with mounting openings 13, and a plurality of first through holes 14 are distributed on the edge of the mounting openings 13. A mounting plate 2 is provided on the upper side of the mounting openings 13, and a plurality of second through holes 21 corresponding to the positions of the first through holes 14 are provided on the edge of the mounting plate 2, and a screw 22 is provided on the upper side of the second through hole 21, and one end of the screw 22 passes through the second through hole 21 and the first through hole 14 and is threadedly connected with a nut 23.

[0028] By passing one end of the screw 22 through the second through hole 21 and the first through hole 14, and then connecting and tightening the screw 23, the mounting plate 2 can be fixedly mounted to both ends of the support plate 1, thereby achieving the effect of convenient disassembly and assembly.

[0029] A shaft sleeve 24 is fixed in the middle of the mounting plate 2, and a lifting shaft 3 is arranged in the shaft sleeve 24. A lifting plate 31 is fixed to the lower end of the lifting shaft 3 after passing through the shaft sleeve 24, the mounting plate 2 and the mounting opening 13. A roller 32 is rotatably arranged at the lower side of the lifting plate 31. An elastic member 33 is arranged between the lifting plate 31 and the mounting plate 2. In this embodiment, the elastic member 33 is a spring, and the elastic member 33 is sleeved on the lifting shaft.

[0030] The upper end of the lifting shaft 3 extends out of the upper end of the shaft sleeve 24 and is threadedly connected to a threaded sleeve 34 . A handle 35 is provided on the upper edge of the threaded sleeve 34 .

[0031] A clamping groove 36 is provided on one side of the lifting shaft 3 , and a clamping block 25 corresponding to the clamping groove 36 is provided inside the shaft sleeve 24 .

[0032] The rollers 32 are located on the inner sides of the two vacuum brushes 11 .

[0033] By rotating the threaded sleeve 34 through the handle 35 , the threaded connection between the lifting shaft 3 and the threaded sleeve 34 can be utilized to move the threaded sleeve 34 up and down on the lifting shaft 3 , thereby adjusting the distance between the threaded sleeve 34 and the lifting plate 31 .

[0034] The elastic member 33, through its own elasticity, pushes the support plate 1 upward through the mounting plate 2, and at this time, the threaded sleeve 34 presses against the top of the shaft sleeve 24, thereby limiting the height of the support plate 1. With the threaded sleeve 34 moving up and down on the lifting shaft 3, the height of the support plate 1 can be controlled, thereby avoiding the problem that the support plate 1 is too low, causing the dust brush 11 to rub against the bottom surface too much and be damaged too quickly, or the support plate 1 is too high, causing the dust brush 11 to be unable to sweep up the garbage.

[0035] The roller 32 facilitates the user to push the support plate 1 forward and backward, so that the dust brush 11 can sweep up the garbage. After the garbage is swept up, it will be sucked away by the dust pipe of the external vacuum cleaner through the access pipe 12, so as to achieve the effect of cleaning the garbage.

[0036] The elastic member 33 can also facilitate the movement of the support plate 1 on uneven ground through its own elastic deformation.

[0037] By locking the locking slot 36 with the locking block 25, the lifting shaft 3 can be prevented from rotating. On the one hand, it is convenient for the user to directly adjust the height of the support plate 1 by rotating the threaded sleeve 34; on the other hand, since the support plate 1 is moved back and forth when the vacuum cleaner is in use, this structure can avoid the rolling direction of the roller 32 from being offset, making it easier for the user to use.

[0038] Since the roller 32 is located at the inner side of the two vacuum brushes 11, when cleaning a corner, the roller 32 will not block the vacuum brushes 11, so that the vacuum brushes 11 can contact and clean the corner.
