Description

Technical Field

[0001] This utility model relates to the field of lifting roller blind technology, specifically an automatic lifting roller blind. Background Technology

[0002] In daily life, many shops use roller blinds as security doors. Currently used roller blinds typically require manual upward pushing to allow them to rise and fall using inertia, resulting in a relatively slow rising and falling rate. Therefore, designing an automatic roller blind is crucial. For example:

[0003] A type of lifting roller blind for a venetian awning, authorized by announcement number CN221920776U, is installed between a ring beam and a column. It includes a roller blind shaft installed within the ring beam, with both ends of the shaft fixed to end caps at the ends of the ring beam. A torque assembly is installed between the roller blind shaft and the end cap at at least one end. A roller blind fabric is wound around the roller blind shaft, with its top fixedly connected to the shaft, a counterweight at its bottom, and several anti-sway buckles on both sides securing it within the column. The fabric then rolls up and down along the column. A pre-tension force is applied to the roller blind shaft via the torque assembly, the magnitude of which is consistent with the weight of the roller blind fabric and the counterweight. This pre-tension force controls the rolling up of the roller blind fabric by applying upward or downward force. In the absence of external force, the roller blind fabric can be suspended at any height. Compared with the prior art, this utility model has the following advantages: The structure is simple and easy to operate, enabling the roller blind to be freely suspended at any height. Specifically, by setting a torque component in cooperation with the roller blind shaft, the torque component applies a pre-tension force to the roller blind shaft. This pre-tension force is consistent with the weight of the roller blind and the counterweight block. When an upward pushing force or a downward pulling force is applied to the counterweight block (i.e., the roller blind), the unfolding or rewinding of the roller blind can be controlled. In the absence of external force (i.e., no external force is applied to the roller blind), the roller blind can be suspended at any height based on the balance between the pre-tension force of the torque component and the weight of the roller blind and the counterweight block. Furthermore, by setting anti-sway buckles on both sides of the roller blind, and placing the anti-sway buckles inside the uprights, not only is the stability of the roller blind's lifting and lowering guaranteed, but also its wind resistance is ensured, preventing the roller blind from swaying due to wind or other external forces.

[0004] Based on existing solutions and actual production and processing, existing roller shutters have the following defects, such as:

[0005] While existing roller blinds prevent the blind fabric from swaying due to wind or other external forces, they are difficult to raise and lower in a short time, resulting in low efficiency. Therefore, this invention provides an automatic roller blind to solve the aforementioned problems. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: an automatic lifting roller blind, including a protective frame 1, a balance plate 2, a roller blind body 3, a protective edge strip 4, a vertical frame 5, a connecting seat body 6, a threaded connecting bolt 7, a force application handle 8, a connector 9, a limiting sleeve 10, a connecting bolt 11, a drive rod body 12, a drive motor 13, a control room 14, a driven block body 15, a drive belt 16, a drive roller body 17, a handwheel 18, and a protective cover body 19.

[0028] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, first, the protective frame 1 is placed horizontally. A vertical frame 5 is set at the lower end of the protective frame 1. The vertical frame 5 is symmetrically arranged about the center line of the protective frame 1. The outer side of the vertical frame 5 is bricked with the wall. The protective cover body 19 is set on the back side of the brick wall and is connected to the protective frame 1 and the vertical frame 5 by bolts. Next, the balance plate 2 is placed horizontally. Connectors 9 are set on both the left and right sides of the balance plate 2. The longitudinal section of the connector 9 is "T" shaped. The balance plate 2 is set at an equal angle about the center of the connector 9. A limiting sleeve 10 is selected.

[0029] Next, after aligning the opening of the limiting sleeve 10 with the center of the connector 9, push it. Friction is generated between the inner wall of the limiting sleeve 10 and the outer wall of the connector 9, and the limiting sleeve 10 and the connector 9 slide together until the outer end face of the connector 9 contacts the limiting sleeve 10. At this time, the connector 9 and the limiting sleeve 10 are engaged. Tighten the connecting bolt 11 at the connection between the connector 9 and the limiting sleeve 10. The connecting bolt 11 has a threaded connection on the outside. When the connecting bolt 11 is tightened, the connection gap between the connector 9 and the limiting sleeve 10 is shortened. Both the connector 9 and the limiting sleeve 10 are threadedly connected to the connecting bolt 11. Under the action of the connecting bolt 11, the connector 9 and the limiting sleeve 10 are fastened together.

[0030] Then, the limiting sleeve 10 is placed inside the protective frame 1, so that the left limiting sleeve 10 is connected to the driven block body 15, and the right limiting sleeve 10 is connected to the drive rod body 12. Finally, the upper ends of the roller shutter body 3 and the protective edge strip 4 are welded to the outside of the balance plate 2, and the force application handle 8 is held so that the bottom end of the connection between the roller shutter body 3 and the protective edge strip 4 is engaged with the connecting seat body 6. The protective edge strip 4 is symmetrically arranged about the center line of the roller shutter body 3. After the connecting seat body 6 is engaged with the roller shutter body 3 and the protective edge strip 4, the threaded connecting bolt 7 is screwed on at the connection between the connecting seat body 6 and the protective edge strip 4 so that the connecting seat body 6 and the protective edge strip 4 are fastened, which facilitates the quick assembly and disassembly of the lifting roller shutter.

[0031] Specific examples Figure 1 , Figure 2 and Figure 4 As shown, a control room 14 is provided at the right end of the protective frame 1. A drive motor 13 is installed inside the control room 14. After the drive motor 13 is powered on, the drive motor 13 drives the drive rod body 12 connected on the left to rotate.
