Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a fast rolling device for a fireproof rolling curtain. Background Art

[0002] In real life, fireproof roller shutters, as a fire-fighting device in the fire-fighting field, have the functions of fire resistance and fire prevention. When a fire occurs, the roller shutters can be automatically retracted and lowered to play a role in fire prevention and protect people from evacuation.

[0003] The rapid winding device for the fireproof roller shutter disclosed in the Chinese utility model patent application disclosure CN214273422U, although, through the winding mechanism arranged on the fireproof roller shutter, the winding of the fireproof roller shutter is different from the winding of the general winding device, and its winding speed is improved to a certain extent. The moving mechanism and cleaning mechanism arranged on both sides of the fireproof roller shutter regularly clean the track of the fireproof roller shutter to ensure that there will be no debris affecting its winding and descending speed in the event of a fire.

[0004] However, there are still certain defects in the above application: when the cleaning mechanism in the above application cleans the track, the debris generated by cleaning the inner wall of the track will fall to the bottom of the track. Over time, as the debris accumulates, the roller shutter may not be able to close normally. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0008] As a further solution of the utility model: the driving assembly includes a third shaft body symmetrically installed at the ends of the two second shaft bodies, a gear is installed on the third shaft body, and a spur rack meshing with the gear is installed on the inner wall of the support track.

[0009] As a further solution of the utility model: the diameter of the gear is smaller than the diameter of the second shaft.

[0010] As a further solution of the utility model: a U-shaped plate is fixedly arranged in the support track, and the end surface of the fireproof roller shutter is slidably arranged in the U-shaped plate.

[0011] As a further solution of the utility model: a plurality of rollers are symmetrically rotatably mounted on the inner wall of the U-shaped plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a cleaning mechanism, and when the fireproof rolling shutter moves from top to bottom, a driving component in the cleaning mechanism can drive the cleaning brush to rotate, which can not only clean the debris on the inner wall of the supporting track, but also throw the debris out of the supporting track, so as to avoid the accumulation of cleaned debris in the supporting track, which makes the fireproof rolling shutter unable to descend normally.

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] See also Figure 1-3A fast winding device for a fireproof rolling curtain 2 comprises a winding mechanism 1 and a fireproof rolling curtain 2, wherein a supporting track 3 is symmetrically arranged below the winding mechanism 1, wherein the side of the fireproof rolling curtain 2 is slidingly arranged in the supporting track 3, and a cleaning mechanism is installed at the bottom thereof, wherein the cleaning mechanism comprises a mounting shaft 4, a cleaning brush 10 and a driving assembly, wherein the mounting shaft 4 comprises a first shaft body 5 and a second shaft body 6 symmetrically arranged at both ends of the first shaft body 5, wherein the diameter of the first shaft body 5 is larger than the diameter of the second shaft body 6, and the first shaft body 5 is rotatably installed on the protective rolling curtain through a bearing sleeve 7, and the first shaft body 5 is rotatably installed on the protective rolling curtain through a bearing sleeve 7. The first limiting nut 8 is symmetrically threadedly installed on both sides of the shaft body 5. The cleaning brush 10 is sleeved on the second shaft body 6 and fixed by the second limiting nut 9. The driving component is used to provide power for the rotation of the installation shaft 4. By setting a cleaning mechanism, when the fireproof roller shutter 2 moves from top to bottom, the driving component in the cleaning mechanism can drive the cleaning brush 10 to rotate, which can not only clean the debris on the inner wall of the support track 3, but also throw the debris out of the support track 3, so as to avoid the accumulation of cleaned debris in the support track 3, causing the fireproof roller shutter 2 to fail to descend normally.

[0020] It is necessary to explain that the winding mechanism 1 is an existing module component, so this embodiment will not be elaborated on it in detail.

[0021] Preferably, the drive assembly includes a third shaft 11 symmetrically installed at the ends of the two second shafts 6, a gear 12 is installed on the third shaft 11, and a spur rack 13 meshing with the gear 12 is installed on the inner wall of the support track 3. The setting of this drive assembly does not require an additional drive element to drive the rotation of the installation shaft 4, and has the advantages of simple structure and low cost.

[0022] In order to ensure that the installation shaft 4 can be smoothly installed on the fireproof roller shutter 2 and the first limiting nut 8 and the second limiting nut 9 can be installed, the diameter of the gear 12 in this application is smaller than the diameter of the second shaft body 6.

[0023] In addition, a U-shaped plate 14 is fixedly arranged in the support rail 3, and the end face of the fireproof roller shutter 2 is slidably arranged in the U-shaped plate 14. The setting of the U-shaped plate 14 can further limit the lifting and lowering of the fireproof roller shutter 2, ensuring that the gear 12 can always engage with the spur rack 13.

[0024] Furthermore, a plurality of rollers 15 are symmetrically mounted on the inner wall of the U-shaped plate 14 for rotation. The arrangement of the rollers 15 reduces the friction between the fireproof rolling shutter 2 and the inner wall of the U-shaped plate 14, making the lifting and lowering of the fireproof rolling shutter 2 smoother.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
