Technical Field
[0001] This utility model relates to the field of roller shutter technology, specifically to a small high-speed metal roller shutter door. Background Technology
[0002] In some testing environments, such as modern factories where humans and machines work together, safety protection devices need to be installed on some potentially dangerous mechanical equipment, such as roller shutters, which can serve as safety isolation. Automatic roller shutters are widely used, but existing roller shutters are not efficient enough. To meet market needs, a small, high-speed metal roller shutter is required.
[0003] Existing roller shutters have a certain time delay during the stopping process, and the trapped objects may suffer some damage. In addition, existing roller shutters are inefficient in raising and lowering, making it difficult to control the curtain's rise or fall efficiently. This also makes roller shutters prone to malfunctions and damage, shortening their lifespan and making them less durable. Utility Model Content
[0004] The purpose of this invention is to provide a small, high-speed metal roller shutter door to solve the problem mentioned in the background art that roller shutter doors are inefficient and not efficient enough during lifting and lowering.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a small high-speed metal roller shutter door, including a door frame, a partition installed on the surface of the center position of the door frame, a frame body installed on the surface of the door frame by screws, a door curtain provided on the inner wall of the frame body, the door curtain slidingly engaging with the inner wall of the linear guide rail, the door curtain being rolled up on the surface of a spiral disc, and a high-efficiency lifting mechanism being provided inside the frame body and the supporting base frame.
[0006] Preferably, the surface of the gantry is fitted with connecting brackets by screws, the interior of the frame is fitted with linear guide rails, and the bottom surface of the gantry is fitted with a supporting base frame.
[0007] Preferably, the bottom surface of the gantry is equipped with casters, which are located inside the supporting base frame. The gantry and the partition are both equipped with spiral discs, and the inner wall of the connecting frame is equipped with a limiting plate for auxiliary support.
[0008] Preferably, the high-efficiency lifting mechanism comprises a top rail box, a bottom rail box, a drive motor, a mounting frame, a rail belt, a guide rail slider, a drive belt guide wheel, and a driven belt guide wheel. The top rail box is installed on the inner wall of the frame, and the bottom rail box is installed inside the frame. The bottom rail box is located below the top rail box. The driven belt guide wheel is installed inside the top rail box, and the driven belt guide wheel rotates with the inner wall of the top rail box. The drive belt guide wheel is installed inside the bottom rail box, and the drive belt guide wheel rotates with the inner wall of the bottom rail box.
[0009] Preferably, a drive motor is installed inside the support base frame. The output end of the drive motor is connected to a rotating shaft via a coupling. One end of the rotating shaft passes through the bottom end box of the linear guide and is fixed to the surface at the center of the drive belt guide wheel. A linear guide belt is installed inside the frame. One end of the linear guide belt passes through the linear guide and extends to the outside of the linear guide. The linear guide belt slides against the inner wall of the linear guide. The bottom end of the linear guide belt passes through the linear guide and the bottom end box of the linear guide in sequence and contacts the surface of the drive belt guide wheel. The top end of the linear guide belt passes through the linear guide and the top end box of the linear guide in sequence and contacts the surface of the driven belt guide wheel.
[0010] Preferably, the surface of the linear guide belt is equipped with a guide rail slider, which slides against the inner wall of the frame. The surface of the guide rail slider is equipped with a mounting bracket via a nail. The surface of the mounting bracket is provided with screw holes, and screws are threaded onto the surface of the screw holes. One end of the screw passes through the mounting bracket and is threadedly fastened to the surface of the curtain.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the small high-speed metal roller shutter door enables the roller shutter door to control the efficient raising or lowering of the curtain during use, and at the same time, it makes the roller shutter door less prone to failure and damage during use, with a longer service life and greater durability;
[0012] Equipped with a high-efficiency lifting mechanism, the drive motor inside the support frame operates. Under the action of the drive motor, the active belt guide wheel rotates inside the bottom box of the linear guide. As the active belt guide wheel rotates, the friction between it and the linear guide belt causes the linear guide belt to slide inside the linear guide rail, guiding the linear guide belt. When the linear guide belt moves, it drives the driven belt guide wheel to rotate on the inner wall of the top box of the linear guide. The combined action of the driven and active belt guide wheels drives the linear guide belt to move within the frame. During this movement, the linear guide belt drives the guide rail slider. The roller shutter moves up and down within the frame. When the guide rail slider moves upward, it drives the mounting frame upward, which in turn drives the curtain upward. At this point, the curtain rolls up onto the surface of the spiral disc, allowing items to pass between the frame and the curtain. When the guide rail slider moves downward, it drives the mounting frame downward, which in turn drives the curtain downward, preventing items from passing between the frame and the curtain. This achieves efficient lifting and lowering of the roller shutter, allowing for precise control of the curtain's ascent and descent. Furthermore, it reduces the likelihood of malfunctions and damage, resulting in a longer service life and greater durability. Attached Figure Description

[0022] The structure of the small high-speed metal roller shutter door provided by this utility model is as follows: Figures 1 to 4 As shown, the system includes a gantry 1, a partition 101 installed on the surface of the center of the gantry 1, a frame 102 installed on the surface of the gantry 1 by screws, a connecting frame 108 installed on the surface of the gantry 1 by screws, a linear guide rail 107 installed inside the frame 102, a support base 103 installed on the surface of the bottom of the gantry 1, and casters 109 installed on the surface of the bottom of the gantry 1, with the casters 109 located inside the support base 103. A spiral disc 106 is installed inside both the gantry 1 and the partition 101. A limiting plate 104 for auxiliary support is installed on the inner wall of the connecting frame 108. A curtain 105 is installed on the inner wall of the frame 102, and the curtain 105 slides and engages with the inner wall of the linear guide rail 107, with the curtain 105 rolled up on the surface of the spiral disc 106.
[0023] Furthermore, such as Figure 5 , Figure 6 and Figure 7As shown, the frame 102 and the supporting base 103 are equipped with a high-efficiency lifting mechanism 2. The high-efficiency lifting mechanism 2 consists of a top rail box 21, a bottom rail box 22, a drive motor 23, a mounting frame 24, a rail belt 25, a guide rail slider 26, a drive belt guide wheel 27, and a driven belt guide wheel 28. The top rail box 21 is installed on the inner wall of the frame 102, and the bottom rail box 22 is installed inside the frame 102. The bottom rail box 22 is located at the top rail box 21. Below, the top box 21 of the linear guide is equipped with a driven belt guide wheel 28, which rotates and engages with the inner wall of the top box 21. The bottom box 22 of the linear guide is equipped with a driving belt guide wheel 27, which rotates and engages with the inner wall of the bottom box 22. The support frame 103 is equipped with a drive motor 23, and the output end of the drive motor 23 is connected to a rotating shaft via a coupling, with one end of the rotating shaft penetrating the bottom of the linear guide. The box 22 is fixed to the surface at the center of the active belt guide wheel 27. The frame 102 is equipped with a linear guide belt 25. One end of the linear guide belt 25 passes through the linear guide rail 107 and extends to the outside of the linear guide rail 107. The linear guide belt 25 slides and engages with the inner wall of the linear guide rail 107. The bottom end of the linear guide belt 25 passes through the linear guide rail 107 and the bottom box 22 and contacts the surface of the active belt guide wheel 27. The top end of the linear guide belt 25 passes through the linear guide rail 107 and the top box 21 and contacts the surface of the driven belt guide wheel 28. A guide slider 26 is installed on the surface of the linear guide belt 25. The guide slider 26 slides and engages with the inner wall of the frame 102. A mounting bracket 24 is installed on the surface of the guide slider 26 through a nail. The surface of the mounting bracket 24 is provided with screw holes, and screws are threaded onto the surface of the screw holes. One end of the screw passes through the mounting bracket 24 and is threaded and fastened to the surface of the curtain 105.
[0024] During implementation, the drive motor 23 inside the control support frame 103 operates. Under the action of the drive motor 23, the active belt guide wheel 27 rotates inside the bottom box 22 of the linear guide. When the active belt guide wheel 27 rotates, the friction between the active belt guide wheel 27 and the linear guide belt 25 causes the linear guide belt 25 to slide inside the linear guide rail 107, guiding the linear guide belt 25. When the linear guide belt 25 moves, it drives the driven belt guide wheel 28 to rotate on the inner wall of the top box 21 of the linear guide. Under the combined action of the driven belt guide wheel 28 and the active belt guide wheel 27, the linear guide belt 25 moves along the frame 102. The internal transmission mechanism of the roller shutter door is as follows: When the linear guide belt 25 is in operation, it drives the guide slider 26 to move up and down on the inner wall of the frame 102. When the guide slider 26 moves upward, it drives the mounting frame 24 to move upward. At this time, the mounting frame 24 drives the curtain 105 to move upward. The curtain 105 is then rolled up on the surface of the spiral disc 106, allowing items to pass between the frame 1 and the curtain 105. When the guide slider 26 moves downward, it drives the mounting frame 24 to move downward. At this time, the mounting frame 24 drives the curtain 105 to move downward, preventing items from passing between the frame 1 and the curtain 105, thus achieving the efficient lifting and lowering function of the roller shutter door.
[0025] Working principle: In use, first place the gantry 1 in the designated position. The support base 103 supports the bottom of the gantry 1. The user operates an external controller to control the drive motor 23 inside the support base 103. The drive motor 23 drives the active belt guide wheel 27 to rotate inside the bottom box 22 of the linear guide. When the active belt guide wheel 27 rotates, the friction between the active belt guide wheel 27 and the linear guide belt 25 causes the linear guide belt 25 to slide inside the linear guide rail 107. Under the action of 107, the linear guide belt 25 is guided. When the linear guide belt 25 moves, it drives the driven belt guide wheel 28 to rotate on the inner wall of the top box 21 of the linear guide. Under the combined action of the driven belt guide wheel 28 and the driving belt guide wheel 27, the linear guide belt 25 is driven to move inside the frame 102. When the linear guide belt 25 is driven, it drives the guide slider 26 to move up and down on the inner wall of the frame 102. When the guide slider 26 moves upward, it drives the mounting frame 24 to move upward. Mounting bracket 24 drives the curtain 105 upward, at which point the curtain 105 rolls up onto the surface of the spiral disc 106, allowing items to pass between the door frame 1 and the curtain 105. When the guide rail slider 26 moves downward, it drives the mounting bracket 24 downward, preventing items from passing between the door frame 1 and the curtain 105. When the curtain 105 rises or falls to the designated position, the limit switch inside the drive motor 23 restricts the curtain 105 from rising or falling. The height is controlled to prevent the curtain 105 from rising or falling excessively. When the limit switch reaches the upper or lower limit, it sends a stop command to the external controller. The controller receives the signal and controls the drive motor 23 to close. The limit switch inside the drive motor 23 is existing technology and will not be described in detail here. This achieves the efficient lifting and lowering function of the roller shutter door, so that the curtain 105 can be controlled to rise or fall efficiently during use. At the same time, it makes the roller shutter door less prone to failure and damage, with a longer service life and greater durability, ultimately completing the use of the roller shutter door.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
