Description
Technical Field
[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a limiting mechanism for anti-theft rolling shutter doors in the financial industry. Background Art
[0002] Rolling shutter doors are made up of multi-jointed door panels connected in series. In a specific slide, the upper and lower doors rotate around the reel above the door, playing the same role as a horizontal partition like a wall. A block is provided in the slide of the rolling shutter door to prevent the door panel from being directly rolled back to the inside of the door head by the reel. The door panel can rise by itself under the rotation of the reel without the need for external force. Rolling shutter doors have the advantages of simple structure and easy maintenance.
[0003] When the rolling door is in use, the door piece returns to the storage bin driven by the rotating shaft. However, due to the setting of the limiting device, a collision will occur between the door piece and the limiting device, which will limit the door piece. The impact force of the collision on the door piece and the door frame is relatively large, and damage is easy to occur. Secondly, when the door piece slides up and down in the door frame, there is a lack of certain restrictions. The distance between the door piece and the door frame is large. During use, the door piece is prone to torsion and deformation, and the gap between the door piece and the door frame is large, which is unsafe to use. Finally, during the use of the door piece, a lot of dust adheres, and the rolling door lacks a self-cleaning function. Therefore, in view of the above problems, a limiting mechanism for anti-theft rolling door in the financial industry is proposed. Utility Model Content

[0022] See also Figure 1-3 , the utility model provides a technical solution:
[0023] A limiting mechanism for an anti-theft rolling shutter door in the financial industry comprises a door head 1, a transverse axis 2, a rolling door 3 and a door frame 17, wherein the door head 1 is rotatably connected to the inside of the transverse axis 2, the rolling door 3 is arranged outside the transverse axis 2, a handle 4 is fixedly connected to the outer end of the rolling door 3 near the edge, a stopper 5 is fixedly connected to one side of the rolling door 3, a groove 6 is arranged at the top of the stopper 5, a first spring 7 is fixedly connected to the bottom end of the groove 6, a baffle 8 is fixedly connected to the top of the first spring 7, the bottom end of the door head 1 is fixedly connected to the door frame 17, a positioning groove 9 is arranged on one side of the door frame 17, a straight shaft 10 is fixedly connected to the inside of the positioning groove 9, and a roller 11 is rotatably connected to the outside of the straight shaft 10.
[0024] A vertical rod 12 is fixedly connected to the inside of the door head 1, and a connecting plate 13 is slidably connected to the outside of the vertical rod 12. A pressure plate 14 is fixedly connected to one end of the connecting plate 13, and a rag 15 is provided at the bottom of the pressure plate 14. A second spring 16 is provided on the outside of the vertical rod 12; the width of the rolling door 3 is slightly smaller than the width of the door frame 17, and the rolling door 3 is wrapped around the outside of the horizontal axis 2; the number of positioning grooves 9, straight shafts 10 and rollers 11 is several, and they are evenly arranged inside the door frame 17; the number of vertical rods 12 and the second spring 16 is four, and the second spring 16 is arranged at the top of the connecting plate 13.
[0025] Working process: The rolling door has been installed at the designated position before use. The main components include the door head 1, the rolling door 3 and the door frame 17. When the rolling door needs to be closed, the rolling door 3 is pulled downward by the handle 4. The rolling door 3 moves downward on the outside of the horizontal axis 2, and the horizontal axis 2 rotates. During the downward movement of the rolling door 3, the roller 11 inside the positioning groove 9 contacts the rolling door 3. When the rolling door 3 moves downward, the roller 11 rotates around the straight axis 10. The rollers 11 are provided on both the inner and outer sides of the rolling door 3, which can adjust the rolling door 3 and the door frame. The spacing between the frames 17 is limited to keep the rolling door 3 in the slideway of the door frame 17, and there will be no collision between the rolling door 3 and the door frame 17. After the rolling door 3 falls to the specified position, the bottom end of the stopper 5 just contacts the blocking part at the bottom end of the door frame 17. At this time, the rolling door 3 reaches the locking position. When it is necessary to open the rolling door, pull the handle 4, and the rolling door 3 is wound around the outside of the horizontal axis 2 through the horizontal axis 2. After the rolling door 3 rises to a certain distance, the baffle 8 at the top of the stopper 5 hits the door frame 17, and the first spring 7 inside the groove 6 The second spring 16 is provided above the connecting plate 13, and the rag 15 is provided above the connecting plate 13. When the rolling door 3 falls, the rag 15 is kept on cleaning the rolling door 3 by the double action of the gravity of the pressing plate 14 and the elastic force of the second spring 16. During the rising process of the rolling door 3, since the rolling door 3 is wound around the outer side of the horizontal axis 2, the pressing plate 14 and the rag 15 are pushed upward by the wound rolling door 3. Due to the action of the second spring 16, the cleaning force of the rag 15 on the rolling door 3 is greater, the cleaning effect is also better, and the dust and other impurities adhered to the rolling door 3 during use can be cleaned.
