[0002] Shutter profile structures are widely used in building decoration, such as shutters. Currently, most of them use aluminum alloy or plastic steel window frames, and curtains are also needed. With the trend of convenience of use, built-in shutter hollow glass windows are becoming more and more popular. Built-in shutter hollow glass windows include aluminum alloy frames, hollow glass, shutters and shutter control devices. The connection of the shutter control device is relatively complicated. The shutters and various control components are connected by pull rope transmission, which easily causes the pull rope to be entangled.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides a louver profile structure cover reinforcement and anti-falling device, including a profile body 1, a wire groove 2 is provided on the profile body 1, a detachable cover plate 3 is provided on the wire groove 2, a vertical plate 4 is provided on one side of the wire groove 2, a T-shaped support plate 5 is provided on the other side of the wire groove 2, a slot 6 is formed between the T-shaped support plate 5 and the profile body 1, a slide groove 7 is provided on the inner surface of the T-shaped support plate 5, a reset spring 8 is fixedly connected in the slide groove 7, a slider 9 is slidably connected in the slide groove 7, one end of the slider 9 is fixedly connected to the reset spring 8, and the other end of the slider 9 is fixedly connected to a limiting block 10, and a limiting hole 11 is provided on the inner surface of the cover plate 3.

[0023] The effect achieved by the entire embodiment 1 is that the pull rope, the guide wheel for guiding the pull rope and the fixed seat are installed in the wire groove 2, and then the cover plate 3 is inserted into the slot 6, so that the limit block 10 is subjected to force, thereby driving the slider 9 to slide into the slide groove 7, and the return spring 8 is squeezed by the slider 9 and begins to shrink. When the cover plate 3 is inserted to the target position, under the elastic force of the return spring 8, the slider 9 drives the limit block 10 to squeeze into the limit hole 11, and then the cover plate 3 is limited and fixed, so as to prevent the cover plate 3 from detaching from the slot 6, thereby preventing the pull rope from squeezing out of the wire groove 2. When the pull rope jumps out of the guide wheel or the pull ropes are entangled during use, the elastic characteristics of the return spring 8 are used to facilitate opening the cover plate 3 to sort and repair the pull rope, and to facilitate replacement of other accessories such as the guide wheel, thereby improving the user experience.

[0024] Embodiment 2, as Figure 1 - Figure 4 As shown, a right-angle bending plate 12 is provided at the lower end of the T-shaped support plate 5, and a guide wheel mounting groove 13 is formed between the right-angle bending plate 12 and the T-shaped support plate 5, a first thermal insulation co-extruded film 14 is provided on the outer surface of the cover plate 3, and two second thermal insulation co-extruded films 15 are provided on the outer surfaces of the profile body 1 and the vertical plate 4, a positioning groove 16 is provided on the top of the T-shaped support plate 5, a positioning column 17 is fixedly connected to the inner surface of the cover plate 3, and the length of the positioning column 17 is greater than the depth of the slot 6, a card slot 18 is provided on the top of the vertical plate 4, and a card block 19 is fixedly connected to the inner surface of the cover plate 3, the card block 19 is located in the card slot 18, and the card block 19 matches the card slot 18, the limit block 10 is located in the limit hole 11, and the limit block 10 matches the limit hole 11, the profile body 1 is made of engineering plastics, and the two second thermal insulation co-extruded films 15 and the first thermal insulation co-extruded film 14 are both made of PMMA resin.

[0025] The effect achieved by the entire embodiment 2 is that the installation and fixation of other components are facilitated by providing a guide wheel installation groove 13, and the installation of the pull rope is realized. Then, the first thermal insulation co-extruded film 14 and the second thermal insulation co-extruded film 15 are provided to enhance the thermal insulation effect of the profile body 1 and the cover plate 3. Then, the length of the positioning column 17 is greater than the depth of the slot 6. When the cover plate 3 is inserted into the slot 6, the positioning column 17 on the inner surface of the cover plate 3 first enters the positioning groove 16, which is convenient for positioning the cover plate 3, thereby facilitating the limit fixation of the cover plate 3. When the cover plate 3 is limit fixed, the block 19 is inserted into the slot 18 at the same time, so that the cover plate 3 and the vertical plate 4 are clamped and installed together, thereby improving the stability of the cover plate 3 after fixation, and facilitating further reinforcement of the cover plate 3.

[0026] Working principle: When in use, the pull rope, the guide wheel for guiding the pull rope and the fixing seat are installed in the wire groove 2, and then the cover plate 3 is inserted into the slot 6. Since the length of the positioning column 17 is greater than the depth of the slot 6, when the cover plate 3 is inserted into the slot 6, the positioning column 17 on the inner surface of the cover plate 3 first enters the positioning groove 16 to position the cover plate 3, and then the limit block 10 is stressed, thereby driving the slider 9 to slide into the slide groove 7, and the return spring 8 is squeezed by the slider 9 and begins to shrink. When the cover plate 3 is inserted to the target position, the slider 9 is driven by the elastic force of the return spring 8. The limit block 10 is squeezed into the limit hole 11, thereby limiting and fixing the cover plate 3. At the same time, the clamping block 19 is inserted into the clamping slot 18, so that the cover plate 3 and the vertical plate 4 are clamped and installed together, preventing the cover plate 3 from escaping from the slot 6, improving the stability of the cover plate 3 after being fixed, and preventing the pull rope from squeezing out of the wire groove 2. When the pull rope jumps out of the guide wheel or the pull ropes become entangled during use, the elastic characteristics of the reset spring 8 can be used to facilitate opening the cover plate 3 to sort and repair the pull rope, and to facilitate the replacement of other accessories such as the guide wheel, thereby improving the user experience.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
