Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtains, in particular to a split type rolling curtain shield and a windproof rolling curtain. Background Art

[0002] As a key component of the windproof roller shutter, the roller shutter cover can not only effectively prevent dust and dirt from directly contacting the surface of the roller shutter cloth, but also play a certain buffering and protective role during the raising and lowering process of the roller shutter cloth, avoiding damage to the roller shutter cloth due to accidental collision, thereby extending the service life of the roller shutter cloth.

[0003] Most of the existing roller shutter guards adopt an integrated design to form an integrated appearance, which not only improves the overall aesthetics, but also enhances the stability of the system. With the popularity of outdoor courtyards, large-sized windproof roller shutters are becoming more and more popular. When installing large-sized, integrated windproof roller shutters, especially those with a support structure to support the roller shutter fabric, the following problems are often encountered:

[0004] Since most roller shutter guards adopt an integrated design, and in order to support large-sized (such as 4-6 meters wide) roller shutter fabrics, a cloth support structure is provided on the bottom cover plate of the roller shutter guard. Since the cloth support structure is mostly made of metal materials and the structure occupies a large space, the user usually needs to support the entire roller shutter guard (including the cloth support structure) at the same time during installation, and install the roller shutter guard in the corresponding position. In this process, due to the large weight of the roller shutter guard itself and the weight of the cloth support structure, the total weight can be as high as 300-500 kilograms, which requires the staff to support a large weight during installation. Not only does it require more staff, resulting in high installation costs, but it also requires high labor intensity and is prone to injury risks. At the same time, since the roller shutter guard adopts an integrated design, the cloth support structure located on the bottom cover plate will hinder the staff from installing the roller shutter guard, which not only increases the difficulty of installation, but also leads to inconvenience and high maintenance costs in subsequent maintenance, affecting the user experience.

[0005] Therefore, there is an urgent need to design a split roller shutter guard and windproof roller shutter, which can independently install and disassemble various parts of the roller shutter guard when the user installs the roller shutter, and can be installed without supporting the entire roller shutter guard (including the support cloth structure), and the installation process is simple and quick, which greatly reduces the weight that needs to be supported by labor during installation, effectively reduces the installation difficulty, labor cost and risk of damage, and at the same time, because the various parts of the roller shutter guard are independent of each other, maintenance is convenient, and when the roller shutter guard has problems or is damaged, there is no need to replace the entire roller shutter guard, which effectively reduces maintenance costs.

[0030] When installing existing roller shutters, it is usually necessary to support the entire roller shutter cover with a support cloth structure. Due to the heavy weight of the roller shutter cover with a support cloth structure, not only more workers are required, resulting in high installation costs, but also high labor intensity and the risk of damage. At the same time, since the roller shutter cover adopts an integrated design, there will be problems of inconvenience and high maintenance costs in subsequent maintenance, which affects the user experience.

[0031] In response to the above-mentioned problems, the embodiments of the present application provide a split roller shutter guard and a windproof roller shutter. When the user installs the roller shutter, the various parts of the roller shutter guard can be independently installed and disassembled. There is no need to support the entire roller shutter guard (including the support cloth structure) for installation, and the installation process is simple and quick, which greatly reduces the weight that needs to be supported by manual labor during installation, effectively reducing the installation difficulty, labor cost and risk of damage. At the same time, since the various parts of the roller shutter guard are independent of each other, maintenance is convenient, and when the roller shutter guard has problems or is damaged, there is no need to replace the entire roller shutter guard, which effectively reduces maintenance costs.

[0032] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] See also Figure 1-Figure 5 The split roller shutter guard of the present application comprises a top cover plate 1, a front cover plate 2, a rear cover plate 3, a bottom cover plate 4, a left cover plate, a right cover plate and a fixing block 5. In order to improve the stability of the roller shutter guard structure and facilitate cleaning and maintenance, the material of the roller shutter guard is preferably any one of stainless steel and aluminum alloy.

[0035] Specifically, the top cover plate 1, the front cover plate 2, the rear cover plate 3, the bottom cover plate 4, the left cover plate and the right cover plate are enclosed to form an accommodating inner cavity, and the rolling curtain cloth is arranged in the accommodating inner cavity. Among them, the top cover plate 1 is arranged below the wall and is fixedly connected to the wall. In the actual installation process, the top cover plate 1 can be fixed to the wall by expansion screws. In order to reduce the installation steps while reducing the installation support weight, the left cover plate and the right cover plate are relatively arranged on both sides of the top cover plate 1, and are integrally formed with the top cover plate 1, that is, by fixing the top cover plate 1, the left cover plate and the right cover plate can be fixed synchronously. It should be noted that in order to facilitate the display of the internal structure of the rolling curtain cover, the left cover plate and the right cover plate in the drawings of the specification have been omitted.

[0036] The bottom cover plate 4 is arranged below the rear cover plate 3 and is fixedly connected to the rear cover plate 3. Specifically, in order to improve the stability of the structure, the rear cover plate 3 and the bottom cover plate 4 are integrally formed, and the cross-sectional shape after forming is L-shaped, that is, the installed rear cover plate 3 is in a vertical state, and the bottom cover plate 4 is in a horizontal state. At this time, a passage for the rolling curtain cloth to be raised and lowered is reserved between the rear cover plate 3 and the installed front cover plate 2. When the width of the rolling curtain cloth is greater than 3 meters, in order to prevent the rolling shaft from being deformed due to the heavy rolling curtain cloth after long-term use, causing the rolling curtain cloth to bend, a cloth support structure 41 is also provided on the bottom cover plate 4. The cloth support structure 41 is fixed to the bottom cover plate 4 through a fixed bracket, and the cloth support structure 41 is arranged along the length direction of the bottom cover plate 4 to support the rolling curtain cloth.

[0037] like Figure 1 As shown, the front cover plate 2 and the rear cover plate 3 are relatively arranged at the two ends of the top cover plate 1, and are detachably connected to the top cover plate 1 respectively. Specifically, the rear cover plate 3 and the top cover plate 1 are provided with mutually adapted clamping structures 6. The clamping structure 6 includes: an L-shaped connecting block is provided at one end of the top cover plate 1, and a 7-shaped connecting block adapted to the L-shaped connecting block is provided at the top end of the rear cover plate 3. When installing, it is only necessary to pick up the rear cover plate 3, and raise the 7-shaped connecting block of the rear cover plate 3 to the opening 7 of the top cover plate 1, and then move it to the left so that the rear cover plate 3 abuts against the top cover plate 1, that is, when the rear cover plate 3 is connected to the top cover plate 1, the L-shaped connecting block and the 7-shaped connecting block abut up and down.

[0038] Since the above-mentioned clamping structure 6 is a straight structure, in order to further prevent the rear cover plate 3 from falling due to mistaken movement toward the opening 7 and to improve the stability of the clamping structure, a preferred parallel scheme of the above-mentioned clamping structure is provided, such as Figure 2-Figure 3As shown, the snap-on structure 6 includes: a female buckle 61 is provided at one end of the top cover plate 1, and the female buckle 61 is in a U-shape as a whole. A male buckle 62 is provided at the top of the rear cover plate 3, and the male buckle 62 is in an inverted U-shape as a whole. The rear cover plate 3 is fixed to the top cover plate 1 by the interlocking of the female buckle 61 and the male buckle 62. When installing, it is only necessary to pick up the rear cover plate 3, and put the male buckle on the rear cover plate 3 into the female buckle, and the male buckle is positioned on three sides by the female buckle, so as to effectively prevent the rear cover plate 3 from falling from the opening 7, and then stabilize the rear cover plate 3 on the top cover plate 1.

[0039] At the same time, in order to further prevent the rear cover plate 3 from falling from the opening 7, the opening 7 is provided with the fixing block 5. Specifically, the fixing block 5 is clamped between the rear cover plate 3 and the top cover plate 1, and abuts against the rear cover plate 3 and the top cover plate 1 respectively, so as to fix the rear cover plate 3 on the top cover plate 1. Figure 2-Figure 3 As shown, the fixed block 5 includes a first abutting block 51 and a second abutting block 52 connected to each other, the first abutting block 51 abuts against the rear cover plate 3, and the second abutting block 52 abuts against the top cover plate 1. That is, the distance between the abutting surface of the first abutting block 51 and the abutting surface of the second abutting block 52 (that is, the overall thickness of the fixed block 5) is equal to the preset distance, and the preset distance is the distance between the rear cover plate 3 vertically placed on the top cover plate 1 and the mouth wall of the opening 7 opposite thereto.

[0040] In order to facilitate the installation of the card block, the upper end of the first abutting block 51 is provided with an inclined protrusion 511, and the lower surface of the inclined protrusion 511 abuts against the top corner of the rear cover plate 3, and the top corner is a chamfered corner. By providing the inclined surface on the first abutting block 51, the friction between the first abutting block 51 and the rear cover plate 3 is effectively reduced during installation, making the installation of the fixed card block 5 more labor-saving.

[0041] When the rear cover plate 3 is fixed to the top cover plate 1 by the fixing block 5, in order to reduce the difficulty of installing the rear cover plate 3, as shown in FIG. Figure 4 As shown, the male buckle 62 includes an active groove 621, and the female buckle 61 includes an active protrusion 611 that is inclined upward; the depth of the active groove 621 is greater than the height of the active protrusion 611, and the width of the active groove 621 is greater than the width of the active protrusion 611, so that the active protrusion 611 can be movably arranged in the active groove 621, and thus the active protrusion 611 does not need to be accurately and tightly fixed in the active groove 621, which reduces the difficulty of installation. During installation, the male buckle 62 on the rear cover plate 3 is placed on the female buckle 61, so that the active protrusion 611 is located in the active groove 621. At this time, as shown in FIG. Figure 4As shown, since the bottom cover plate 4 and the rear cover plate 3 are integrally connected, the center of gravity problem causes the lower end of the rear cover plate 3 to move in the direction away from the front cover plate 2, that is, the rear cover plate 3 is in an inclined state, and then the fixed card block 5 is placed at the opening 7, and then an upward force is applied to the fixed card block 5, and then an upward force is applied to the top end of the rear cover plate 3, so that the lower end of the rear cover plate 3 moves toward the direction of the front cover plate 2 until the rear cover plate 3 is in a vertical state, and the fixed card block 5 is respectively in contact with the rear cover plate 3 and the top cover plate 1 (as shown in FIG. Figure 5 shown).

[0042] In order to facilitate the removal of the fixed block 5, the fixed block 5 further includes a removal groove 53, which is arranged at the bottom end of the first abutting block 51, and the notch of the removal groove 53 faces the front cover plate 2. When removing, the fixed block 5 can be taken out from the opening 7 by simply inserting a hand or other tool into the removal groove 53 and then applying a downward force to the lower groove wall of the removal groove 53.

[0043] The other end of the top cover plate 1 is provided with an arc-shaped groove 8, and the top end of the front cover plate 2 is provided with an arc-shaped convex strip 9 adapted to the arc-shaped groove 8. When installing the front cover plate 2, the arc-shaped convex strip 9 is first placed in the arc-shaped groove 8, and then the lower end of the front cover plate 2 is respectively connected to the left cover plate and the right cover plate through expansion screws, thereby completing the installation and fixation of the front cover plate 2.

[0044] During installation, first, according to the installation position of the rolling shutter guard, fix the top cover plate 1 (the left cover plate and the right cover plate are integrally connected to it) on the wall by expansion screws, then pick up the rear cover plate 3 (the bottom cover plate 4 and the support structure 41 are integrally connected to it), and position the rear cover plate 3 on the top cover plate 1 by the clamping structure 6 between the rear cover plate 3 and the top cover plate 1, and then place the fixed card block 5 at the opening 7, and apply an upward thrust to the fixed card block 5, so that the fixed card block 5 can be clamped at the opening 7 and respectively with the The rear cover plate 3 and the top cover plate 1 are abutted, and then the bottom cover plate 4 is connected to the left cover plate and the right cover plate respectively by expansion screws, so that when the rolling curtain cloth is placed on the cloth support structure 41 on the bottom cover plate 4, the left cover plate and the right cover plate can simultaneously share the weight of the rolling curtain cloth, making the structure of the entire rolling curtain guard more stable, and finally the arc convex strip 9 of the front cover plate 2 is installed at the arc groove 8 of the top cover plate 1, and then the lower end of the front cover plate 2 is connected to the left cover plate and the right cover plate respectively by expansion screws, thereby completing the installation of the entire rolling curtain guard. When disassembling, you only need to reverse the steps, which will not be repeated here.

[0045] In the first embodiment, the split roller shutter guard provided by the present application includes a top cover plate, a front cover plate, a rear cover plate, a bottom cover plate, a left cover plate, a right cover plate and a fixed block. By setting the top cover plate and the bottom cover plate to be detachably connected, the personnel can sequentially install the top cover plate and the left cover plate and the right cover plate integrally connected thereto, the rear cover plate and the bottom cover plate and the support cloth structure integrally connected thereto, the roller shutter cloth, and the front cover plate during installation. Compared with the existing installation method that requires the entire roller shutter guard (including the support cloth structure) to be supported at the same time, the solution provided by the present application can independently install and disassemble various parts of the roller shutter guard, and can be installed without supporting the entire roller shutter guard (including the support cloth structure), and the installation process is simple and quick, which greatly reduces the weight that needs to be supported by manual labor during installation, effectively reducing the difficulty of installation, labor costs and damage risks. At the same time, since the various parts of the roller shutter guard are independent of each other, maintenance is convenient, and when the roller shutter guard has problems or is damaged, there is no need to replace the entire roller shutter guard, which effectively reduces maintenance costs.
