Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to a mesh anti-theft roller shutter. Background Technology

[0002] In the field of modern commercial and residential security, burglarproof roller shutters are widely used as an important security facility.

[0003] In the existing technology, most roller blinds on the market are solid. When closed, the air circulation between indoors and outdoors is severely obstructed. Especially in the hot summer or in places with high ventilation requirements, prolonged use can lead to stuffy and humid indoor air, affecting environmental comfort and air quality. On the other hand, existing anti-theft roller blinds have openings in them to achieve ventilation, but their function is relatively simple and lacks a flexible adjustment mechanism. They cannot adjust the ventilation volume and direction according to actual needs, making it difficult to meet the diverse usage scenarios of users. Therefore, a mesh anti-theft roller blind is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mesh anti-theft roller shutter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mesh anti-theft roller shutter includes a mounting housing. Door frames are installed on the left and right sides of the lower end of the mounting housing. A winding roller is rotatably connected inside the mounting housing. Multiple sets of door panels are wound onto the outer wall of the winding roller. Each set of door panels slides within two sets of door frames at its two side edges. Ventilation holes are provided through the outer walls of the multiple sets of door panels close to the mounting housing. A transmission box is installed on the outer wall of each door frame. A mounting frame is fixedly connected between two sets of transmission boxes. The mounting frame is located at the multiple sets of ventilation holes. Multiple sets of air guide plates are rotatably connected inside the mounting frame. Each set of air guide plates is rotatably connected to each other via connecting plates. A drive assembly is installed inside the transmission box to drive the multiple sets of air guide plates to rotate synchronously.

[0006] Preferably, the drive assembly includes a toothed plate slidably connected in the transmission box, a gear rotatably connected in the transmission box and meshing with the toothed plate, and the gear being coaxially and fixedly connected with its adjacent air guide plate.

[0007] Preferably, a threaded rod is rotatably connected to the bottom of the transmission box, and a slider is threadedly connected to the threaded section of the threaded rod, with the toothed plate fixedly connected to the end face of the slider.

[0008] Preferably, a limiting rod is fixedly connected to the bottom of the transmission box, the slider is slidably connected to the outer wall of the limiting rod, and a limiting block is fixedly connected to the end of the threaded rod, the radius of the limiting block being larger than the radius of the threaded rod.

[0009] Preferably, both sets of door frame outer walls are fixedly connected with a card plate, and the end face of the card plate is provided with an installation groove. Both sets of transmission box outer walls are fixedly connected with a card block. The outer wall of the card block and the inner wall of the card plate are both T-shaped, and the card block is engaged in the installation groove.

[0010] Preferably, a servo motor is fixedly connected to the lower end of the transmission box, and a drive motor is installed inside the mounting housing. The servo motor and the drive motor are respectively fixedly connected coaxially to the threaded rod and the take-up roller.

[0011] This utility model has the following beneficial effects: 1. This utility model uses a servo motor to drive a threaded rod to synchronously deflect the air guide plate. Operators can easily adjust the ventilation area and airflow direction of the ventilation holes. It can maintain the maximum ventilation volume under normal conditions, reduce the ventilation area and change the airflow direction in strong winds, and completely close the ventilation holes when needed. This effectively solves the problem that traditional roller shutters have a single ventilation function and cannot adapt to diverse usage scenarios.

[0012] 2. This utility model ensures the anti-theft security of the roller shutter when it is closed by cooperating with the door panel and the door frame. The T-shaped cooperation structure of the card block and the card plate makes the disassembly and assembly of the transmission box simple and quick, which not only avoids the loosening of parts caused by frequent use, but also facilitates later maintenance and improves the practicality and service life of the product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-5 The mesh anti-theft roller shutter includes a mounting housing 1. Door frames 3 are installed on the left and right sides of the lower end of the mounting housing 1. A winding roller 2 is rotatably connected inside the mounting housing 1. Multiple sets of door panels 4 are wound up on the outer wall of the winding roller 2. The edges of each set of door panels 4 slide within the two sets of door frames 3. Ventilation holes 5 are opened through the outer wall of the multiple sets of door panels 4 close to the mounting housing 1. A transmission box 6 is installed on the outer wall of each door frame 3. A mounting frame 11 is fixedly connected between the two sets of transmission boxes 6. The mounting frame 11 is located at the multiple sets of ventilation holes 5. Multiple sets of air guide plates 10 are rotatably connected inside the mounting frame 11. Each set of air guide plates 10 is rotatably connected to each other through a connecting plate 12. A drive assembly for driving the multiple sets of air guide plates 10 to rotate synchronously is installed inside the transmission box 6. Furthermore, by setting ventilation holes 5 on the door panel 4, the problem of severe obstruction of indoor and outdoor air circulation when the traditional solid roller shutter is closed is effectively solved, avoiding stuffy and humid indoor air in hot summers or places with high ventilation requirements, thus improving environmental comfort and air quality. In addition, multiple sets of rotatable air guide plates 10, together with the drive components, can flexibly adjust the ventilation volume and ventilation direction according to actual needs, which can better meet the diverse usage scenarios of users.

[0020] The drive assembly includes a toothed plate 16 slidably connected in the transmission box 6, a gear 17 rotatably connected in the transmission box 6 and meshing with the toothed plate 16, and the gear 17 is coaxially fixedly connected to its adjacent air guide plate 10. Furthermore, the drive structure in which the toothed plate 16 and the gear 17 mesh with each other can stably and reliably convert the linear motion of the toothed plate 16 into the rotational motion of the gear 17 and the air guide plate 10, ensuring that multiple sets of air guide plates 10 can rotate synchronously and accurately, thereby achieving precise adjustment of ventilation volume and ventilation direction, and avoiding unstable ventilation adjustment.

[0021] A threaded rod 13 is rotatably connected to the bottom of the transmission box 6. A slider 15 is threadedly connected to the threaded section of the threaded rod 13. A toothed plate 16 is fixedly connected to the end face of the slider 15. A limit rod 14 is fixedly connected to the bottom of the transmission box 6. The slider 15 is slidably connected to the outer wall of the limit rod 14. A limit block 18 is fixedly connected to the end of the threaded rod 13. The radius of the limit block 18 is larger than the radius of the threaded rod 13. Furthermore, the threaded transmission design of the threaded rod 13 and the slider 15 allows the slider 15 to slide easily and smoothly by rotating the threaded rod 13, thereby driving the toothed plate 16 to move.

[0022] Both sets of door frames 3 are fixedly connected to the outer walls of the card plates 8, and the end face of the card plates 8 is provided with an installation groove. Both sets of transmission boxes 6 are fixedly connected to the outer walls of the card blocks 9. The outer wall of the card blocks 9 and the inner wall of the card plates 8 are T-shaped, and the card blocks 9 are locked in the installation groove. The lower end of the transmission box 6 is fixedly connected to the servo motor 7. The mounting housing 1 is equipped with a drive motor. The servo motor 7 and the drive motor are respectively fixedly connected to the threaded rod 13 and the winding roller 2 on the same axis. Furthermore, the mating structure of this T-shaped card block 9 and the mounting groove of the card plate 8 makes the installation and disassembly process between the transmission box 6 and the door frame 3 simple and quick.

[0023] In this invention, the device is used as follows: When the operator starts the device, the winding roller 2 rotates under the action of the drive motor, causing multiple sets of door panels 4 to unfold downwards along the door frame 3 until the mesh anti-theft roller shutter is completely closed. At this time, the ventilation holes 5 are open, and outdoor air can flow naturally into the room through the ventilation holes 5, alleviating the airflow obstruction problem caused by traditional solid roller shutters. The air guide plate 10 is horizontally unfolded in the initial position, maximizing the ventilation area of ​​the ventilation holes 5, which is suitable for scenarios with conventional ventilation needs.

[0024] When it is necessary to adjust the ventilation volume or airflow direction, the operator drives the threaded rod 13 to rotate by controlling the servo motor 7. When the threaded rod 13 rotates, the slider 15 slides in a straight line under the constraint of the limit rod 14, driving the toothed plate 16 to move synchronously. The toothed plate 16 meshes with the gear 17, converting the linear motion into the rotational motion of the gear 17, which in turn drives the air guide plate 10, which is fixed coaxially with it, to deflect around the rotation axis of the mounting frame 11. Since multiple sets of air guide plates 10 are linked in pairs through the connecting plate 12, the rotation of one side of the air guide plate 10 is transmitted to the adjacent air guide plate 10 through the connecting plate 12, realizing the synchronous angle adjustment of multiple sets of air guide plates 10.

[0025] When the air guide plate 10 deflects upward, the effective ventilation area of ​​the ventilation hole 5 gradually decreases, and the airflow direction is guided to the upper angle, which is suitable for scenarios that require reducing the direct airflow speed or controlling the ventilation volume, such as in strong winds. When the air guide plate 10 deflects downward, the ventilation area of ​​the ventilation hole 5 further expands, and the airflow direction tends to be horizontal, which can improve air exchange efficiency and meet the rapid ventilation needs in high temperature and high humidity environments. Through the precise control of the rotation angle of the threaded rod 13 by the servo motor 7, the air guide plate 10 can stay at any intermediate angle, realizing stepless adjustment of ventilation volume and airflow direction.

[0026] In the anti-theft mode with the roller shutter fully closed, the door panel 4 and the door frame 3 fit tightly together, and together with the air guide plate 10, it can effectively prevent external tools from entering through the ventilation hole 5. If it is necessary to completely block ventilation, the operator can rotate the air guide plate 10 to a vertical closed state through the drive component, so that multiple sets of air guide plates 10 are tightly stacked, completely sealing the ventilation hole 5 and forming a continuous protective surface.

[0027] The T-shaped mating structure of the locking block 9 and the locking plate 8 ensures the connection stability between the transmission box 6 and the door frame 3, preventing component loosening due to frequent opening and closing of the roller shutter. If disassembly and maintenance are required, the operator can slide the transmission box 6 laterally along the mounting groove of the locking plate 8 to quickly separate the locking block 9 from the mounting groove, allowing for modular disassembly and assembly without additional tools.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
