Description
Technical Field
[0001] The utility model relates to the technical field of rolling curtains, in particular to a high-strength windproof rolling curtain. Background Art
[0002] The main function of roller blinds is to isolate the outside world and maintain the privacy of the room. At the same time, it is an indispensable decoration for home decoration. Different settings of indoor curtains will give people completely different feelings and become a beautiful landscape indoors. In order to make roller blinds more practical, more beautiful, and more suitable for the needs of outdoor sun room shading and shielding, the windproof roller blinds came into being.
[0003] The existing windproof roller blinds have poor positioning effect when unfolded. In strong winds, they are easy to move, which reduces the windproof effect. There is no fixing device under the roller blinds, so the lower end is easy to be blown open by strong winds. At the same time, under long-term exposure to the sun, the roller blinds are easy to deform and wrinkle, causing size changes, thus affecting their windproof effect and service life. In view of the above problems, a solution is proposed below. Utility Model Content
[0004] The utility model aims to provide a high-strength windproof rolling curtain, which has the advantages of good positioning windproof effect and can prevent the rolling curtain from being deformed.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:
[0006] A high-strength windproof roller shutter, comprising a roller shutter body, two guide rails and a bottom fixed seat, guide rubber strips are respectively fixed on both sides of the roller shutter body, and the two guide rubber strips are respectively matched with the two guide rails, and a fixed frame is fixed at the lower end of the roller shutter body, and a plurality of rotatable connecting hooks are arranged in the fixing frame, and a plurality of groups of limiting mechanisms are also arranged in the fixing frame, and the plurality of groups of limiting mechanisms are respectively matched with the connecting hooks, and a plurality of guide cylinders are fixed in the bottom fixed seat, and slidable guide columns are respectively passed through the plurality of guide cylinders, and an adjusting spring is respectively fixed in each of the guide cylinders, and the upper end of the adjusting spring is fixedly connected to the lower end of the guide column, and the upper ends of the plurality of guide columns are respectively fixed with fixing rings, and the fixing rings are matched with the connecting hooks.
[0007] Preferably, the limiting mechanism includes a plurality of limiting pins passed through the fixing frame, wherein the plurality of limiting pins are respectively located obliquely below the connecting hook and respectively fit with the lower side of the connecting hook, and each limiting pin is respectively passed through a return spring, and the return spring is connected between the outer wall of the fixing frame and the tail end of the limiting pin.
[0008] Preferably, a plurality of groups of limit blocks are fixedly disposed on the outer sides of the two guide rails, and the plurality of groups of limit blocks are elastic.
[0009] Preferably, a plurality of fixing holes are respectively provided on the inner sides of the two guide rails.
[0010] The beneficial effects of the utility model are:
[0011] 1. When the roller shutter body is unfolded, the guide strips at both ends can be slidably embedded in the two guide rails respectively, so that the roller shutter can be prevented from being blown up by strong wind, thereby playing a windproof role, and pulling force can be applied to both ends of the roller shutter to prevent the roller shutter from being deformed and shrinking and wrinkling under the sun. When the roller shutter is unfolded downward, several connecting hooks can be hooked into the fixing ring respectively. If a strong wind blows the roller shutter, the connecting hook can pull the fixing ring, that is, pull the guide column to slide up and down along the inside of the guide cylinder, so that the adjustment spring can generate elastic force. At this time, the elastic force of the adjusting spring can be adjusted to keep the tension on the roller shutter constant, and the lower end of the roller shutter can be tightened when the roller shutter is exposed to the sun, which can further prevent the roller shutter from being deformed, thereby ensuring the efficient windproof effect of the roller shutter.
[0012] 2. The two guide rails can be installed through several fixed installation holes. In fact, they can be installed on the inner edge of the window frame or door frame to prevent them from protruding and affecting the aesthetic effect. Several sets of limit blocks can prevent the two ends of the roller shutter from escaping from the guide rails to ensure its windproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0019] like Figures 1 to 4 As shown, a high-strength windproof roller shutter comprises a roller shutter body 1, two guide rails 2 and a bottom fixing seat 3. Guide rubber strips are fixed on both sides of the roller shutter body 1, and the two guide rubber strips are respectively matched with the two guide rails 2. When the roller shutter body 1 is unfolded, the guide rubber strips at both ends can be slidably embedded in the two guide rails 2, thereby preventing the roller shutter from being blown up by strong wind, thereby playing a windproof role, and pulling force can be applied to both ends of the roller shutter to prevent the roller shutter from being deformed and shrinking and wrinkling under exposure to the sun.
[0020] Several groups of stop blocks 14 are fixed on the outside of the two guide rails 2. The groups of stop blocks 14 are elastic and can prevent the two ends of the roller blind from coming off the guide rails 2 to ensure its windproof effect. Several fixing holes 15 are respectively opened on the inside of the two guide rails 2. The two guide rails 2 can be installed through the several fixing holes 15. In fact, they can be installed on the inner edge of the window frame or door frame to prevent them from protruding and affecting the aesthetic effect.
[0021] A fixing frame 5 is fixed at the lower end of the roller shutter body 1, and a plurality of rotatable connecting hooks 6 are arranged in the fixing frame 5. A plurality of guide cylinders 8 are fixed in the bottom fixing seat 3, and a plurality of slidable guide columns 9 are respectively penetrated in the plurality of guide cylinders 8. An adjusting spring 10 is fixed in each guide cylinder 8, and the upper end of the adjusting spring 10 is fixedly connected to the lower end of the guide column 9. A fixing ring 11 is fixed at the upper end of the plurality of guide columns 9, and the fixing ring 11 cooperates with the connecting hook 6. When the roller shutter is unfolded downward, the roller shutter can be moved downward. A plurality of connecting hooks 6 are hooked into the fixing ring 11 respectively. When a strong wind blows the rolling curtain, the connecting hook 6 can pull the fixing ring 11, that is, pull the guide column 9 to slide up and down along the inside of the guide tube 8, so that the adjusting spring 10 can generate elastic force. At this time, the elastic force of the adjusting spring 10 can be adjusted to keep the tension on the rolling curtain constant, and the lower end of the rolling curtain can be tightened when the rolling curtain is exposed to the sun, which can further prevent the rolling curtain from being deformed, thereby ensuring the efficient windproof effect of the rolling curtain.
[0022] Several groups of limiting mechanisms 7 are also provided in the fixing frame 5, and the several groups of limiting mechanisms 7 cooperate with the connecting hooks 6 respectively. The limiting mechanisms 7 can support the connecting hooks 6 when the roller blind is retracted, so as to hide the connecting hooks 6 in the fixing frame 5 to ensure its aesthetic effect. The limiting mechanism 7 includes a plurality of limiting pins 12 passed through the fixing frame 5, and the plurality of limiting pins 12 are respectively located obliquely below the connecting hook 6 and respectively fit with the lower side of the connecting hook 6. A reset spring 13 is respectively passed through each limiting pin 12, and the reset spring 13 is connected between the outer wall of the fixing frame 5 and the tail end of the limiting pin 12. By pulling the limiting pin 12 outward, the limiting pin 12 can slide outward along the fixing frame 5. At this time, the reset spring 13 is stretched to generate elastic force. When the limiting pin 12 is separated from the connecting hook 6, the connecting hook 6 can be rotated, so that the connecting hook 6 can be connected to the fixing ring 11. On the contrary, when the limiting pin 12 is in the initial position, it can support the lower side of the connecting hook 6, so that the hook can be hidden in the fixing frame 5.
