Description

Technical Field

[0001] This utility model relates to the field of windproof roller shutter technology, and specifically discloses an automatically adjustable windproof roller shutter. Background Technology

[0002] The main structural principle of windproof roller blinds is very similar to that of indoor window covering roller blinds. However, windproof roller blinds use special accessory construction and processing technology to effectively integrate the fabric and various accessories into a whole. The fabric is fixed in the guide rails on both sides and can move up and down, thus having wind resistance.

[0003] Traditional windproof roller shutters are prone to deformation of the guide rails, tearing of the curtains, or complete detachment due to concentrated wind pressure in strong wind environments. Existing windproof roller shutters mostly use reinforced frames or additional fixing points, but the structure is complex, the cost is high, and they cannot dynamically respond to instantaneous changes in wind pressure, so there are still safety hazards. Utility Model Content

[0004] This invention proposes an automatically adjustable windproof roller shutter. Through the cooperation of the redundant space of the guide groove and the buffer component, the main body of the roller shutter can be laterally displaced under strong winds to release instantaneous stress, fundamentally avoiding guide rail deformation or curtain tearing.

[0005] This utility model is implemented as follows: an automatically adjustable windproof roller blind includes a roller blind body, a winding mechanism, and a counterweight rod. Guide rails are fixedly connected to both the left and right sides of the lower end face of the winding mechanism. The two guide rails are symmetrically arranged, and slots are opened on opposite sides. Guide grooves are opened at the rear ends of the two guide rails. Sliding members are slidably connected inside the two guide grooves. The width of the guide groove is greater than the width of the sliding member. A buffer plate is provided inside the guide groove and on the side closer to the roller blind body. A buffer assembly is provided between the buffer plate and the inner sidewall of the guide groove.

[0006] In a preferred embodiment of the automatically adjustable windproof roller shutter of this utility model, each of the two sliding members has a vertical block fixedly connected to its front end face, and each of the two vertical blocks has a connecting rib fixedly connected to both ends of the counterweight rod.

[0007] As a preferred embodiment of the automatically adjustable windproof roller shutter of this utility model, the buffer assembly includes a damping rubber fixedly connected to the inner wall of the guide groove, and a compression spring fixedly connected to the side of the damping rubber facing the buffer plate.

[0008] As a preferred embodiment of the automatically adjustable windproof roller shutter of this utility model, the compression springs and damping rubbers are provided in multiple quantities and are evenly spaced along the height direction of the guide groove.

[0009] As a preferred embodiment of the automatically adjustable windproof roller shutter of this utility model, the connecting rib is made of highly elastic polyethylene material with pre-stretching capacity.

[0010] In a preferred embodiment of this utility model of an automatically adjustable windproof roller shutter, the width of the guide groove is 1.2-1.5 times the width of the sliding member.

[0011] The beneficial effects of this utility model are:

[0012] This invention, through the combination of redundant space in the guide groove and buffer component, enables the roller shutter body to move laterally under strong winds to release instantaneous stress, fundamentally avoiding guide rail deformation or curtain tearing. The buffer component self-resets after the wind stops, and the highly elastic connecting ribs and buffer component further disperse dynamic loads, improving impact resistance and reliability. The overall structure only adds a buffer component to the traditional roller shutter, achieving active wind protection without the need for complex external mechanisms, significantly extending service life and simplifying maintenance.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-3An automatically adjustable windproof roller blind includes a roller blind body 1, a winding mechanism 2, and a counterweight rod 3. Guide rails 4 are fixedly connected to the left and right sides of the lower end face of the winding mechanism 2. The two guide rails 4 are symmetrically arranged and have slots on opposite sides. Guide grooves 5 are opened at the rear end of the inner side of the two guide rails 4. Sliding parts 6 are slidably connected inside the two guide grooves 5. The width of the guide groove 5 is greater than the width of the sliding part 6. A buffer plate 9 is provided inside the guide groove 5 and on the side closer to the roller blind body 1. A buffer assembly is provided between the buffer plate 9 and the inner sidewall of the guide groove 5.

[0020] In this embodiment: the roller blind body 1 is controlled to rise and fall by the winding mechanism 2, the counterweight rod 3 improves the stability of the blind body, the guide groove 5 opened inside the guide rail 4 forms a sliding pair with the sliding member 6, the width of the guide groove 5 is greater than the width of the sliding member 6, thus reserving a buffer zone for the lateral displacement of the sliding member 6. Under normal conditions, the sliding member 6 and the buffer plate 9 do not contact each other. The counterweight rod 3 is made of flexible material. When there is a strong wind, the wind pressure drives the roller blind body 1 to move backward. The counterweight rod 3 drives the connecting ribs 8 on both sides to move towards the center, thereby driving the sliding member 6 to squeeze the buffer plate 9. The compression spring 11 contracts and the damping rubber 10 deforms to absorb energy, dynamically releasing stress to avoid hard damage. After the wind stops, the buffer assembly automatically resets, so that the roller blind body 1 can release instantaneous stress by lateral displacement under strong wind, fundamentally avoiding guide rail deformation or curtain tearing. Active windproofing is achieved without the need for a complex external mechanism, significantly extending the service life and simplifying maintenance.

[0021] As a technical optimization of this utility model, the front ends of the two sliding parts 6 are fixedly connected with the upright blocks 7, and the two upright blocks 7 are fixedly connected with the two ends of the counterweight rod 3 with the connecting ribs 8.

[0022] In this embodiment: when wind pressure acts on the main body 1 of the roller shutter, the counterweight rod 3 drives the connecting ribs 8 on both sides to move closer to the center, thereby driving the sliding part 6 to squeeze the buffer plate 9, the compression spring 11 to contract and the damping rubber 10 to deform and absorb energy, and the connecting ribs 8 to elastically extend to help disperse stress and reduce local impact.

[0023] As a technical optimization of this utility model, the buffer assembly includes a damping rubber 10 fixedly connected to the inner wall of the guide groove 5, and a compression spring 11 fixedly connected to the side of the damping rubber 10 facing the buffer plate 9.

[0024] In this embodiment: the damping rubber 10 absorbs high-frequency vibrations, the compression spring 11 buffers and provides the main body's rebound force, and the multi-level buffer adapts to different wind pressure intensities to avoid resonance damage.

[0025] As a technical optimization of this utility model, multiple compression springs 11 and damping rubbers 10 are provided and evenly arranged at intervals along the height direction of the guide groove 5.

[0026] In this embodiment, multiple compression springs 11 and damping rubbers 10 are provided and evenly spaced along the height direction of the guide groove 5, so that the buffer plate 9 is subjected to uniform force.

[0027] As a technical optimization of this utility model, the connecting rib 8 is made of highly elastic polyethylene material with pre-stretching.

[0028] In this embodiment, the connecting rib 8 is made of high-elasticity polyethylene, which has good elasticity and strong toughness. When subjected to wind pressure, the connecting rib 8 itself can buffer and absorb part of the pressure and impact, thereby improving the buffering effect.

[0029] As a technical optimization of this utility model, the width of the guide groove 5 is 1.2-1.5 times the width of the sliding member 6.

[0030] In this embodiment, the width of the guide groove 5 is 1.2-1.5 times the width of the slider 6, which controls the maximum displacement of the slider 6 and balances the sealing performance and wind resistance.

[0031] The working principle and usage process of this utility model: Under normal conditions, the sliding part 6 and the buffer plate 9 do not contact each other. The counterweight rod 3 is made of flexible material. When there is a strong wind, the wind pressure drives the main body 1 of the roller blind to move backward. The counterweight rod 3 drives the connecting ribs 8 on both sides to move towards the center, thereby causing the sliding part 6 to squeeze the buffer plate 9. The compression spring 11 contracts and the damping rubber 10 deforms to absorb energy, dynamically releasing stress to avoid hard damage. After the wind stops, the buffer assembly automatically resets, so that the main body 1 of the roller blind can move laterally under strong wind to release instantaneous stress, fundamentally avoiding guide rail deformation or curtain tearing.
