Description

Technical Field

[0001] This utility model relates to the field of building smoke curtain technology, specifically a smoke curtain installation structure. Background Technology

[0002] Smoke curtains are devices installed under ceilings or floors to block the spread of smoke and reduce the random dispersal of smoke and hot gases during a fire. They are mainly used in large supermarkets or places with high population density, and can effectively separate smoke and dust, thus protecting people's lives and property.

[0003] Chinese Patent No. CN 215759924 U discloses a smoke curtain installation structure, including: a concrete top, an expansion bolt connected to the lower end of the concrete top, a fixing rod connected to the bottom of the expansion bolt, a first lifting component connected to the bottom of the fixing rod, a U-shaped fixing member connected to the right side of the first lifting component, a smoke baffle plate connected to the bottom inner cavity of the U-shaped fixing member by bolts, and edge posts connected to the left and right ends of the smoke baffle plate, with a second lifting component connected to the inner cavity of the edge posts.

[0004] As can be seen from the above, the device moves up and down by means of a second sliding rod. The upper end of the second sliding rod is fixed to the bottom of the expansion bolt, and the lower end of the second sliding rod is connected to the upper end of the ceiling surface, so that the vertical force of the smoke baffle is distributed on the concrete top and the ceiling surface, increasing its bearing area and reducing the risk of the smoke baffle falling off. However, this solution also has the following shortcomings: the device is not easy to disassemble, and the damage caused to the house after disassembly requires further labor for repair. In addition, the bottom of the smoke baffle is not fixed in a certain way. If strong winds occur during use, the effectiveness of the smoke baffle will be greatly reduced.

[0005] Therefore, a smoke curtain installation structure is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a smoke curtain installation structure that has the advantages of not damaging the wall, enabling rapid installation, and facilitating transportation, thus solving the problem of wall damage caused by existing solutions.

[0007] To achieve the aforementioned goal of installing smoke baffles quickly and to a certain extent, without damaging the wall, this utility model provides the following technical solution: a smoke baffle wall installation structure, including a smoke-blocking cloth, characterized in that: a first locking block is snapped onto the front of the smoke-blocking cloth; a limiting slide bar is slidably connected to the outer surface of the first locking block; a fixing block is fixedly connected to one end of the limiting slide bar; a second screw is fixedly connected to the end of the fixing block away from the limiting slide bar; a first limiting cylinder is threaded onto the outer surface of the second screw; the first limiting cylinder... A third screw is threadedly connected to the inner wall of the first limiting cylinder at the end away from the second screw. A first limiting ring is fixedly connected to the end of the third screw away from the first limiting cylinder. A first limiting block is rotatably connected to the inner wall of the first limiting ring by bolts. A fixing plate is fixedly connected to one side of the first limiting block. A second limiting block is fixedly connected to one side of the fixing plate. A second limiting ring is rotatably connected to the inner wall of the second limiting block by bolts. A fourth screw is fixedly connected to the outer surface of the second limiting ring. A second limiting cylinder is threadedly connected to the outer surface of the fourth screw.

[0008] Furthermore, the end of the second limiting cylinder away from the fourth screw is threadedly connected to the first screw, and the end of the first screw away from the second limiting cylinder is fixedly connected to the third limiting ring. A limiting groove is formed on one side of the fixing block.

[0009] Furthermore, the inner wall of the limiting groove is rotatably connected to a third limiting ring by bolts, the front side of the smoke-proof cloth is snapped with a first clamping block, and the inner wall of the first clamping block is rotatably connected to a second clamping block by a connecting column.

[0010] Furthermore, both ends of the first clamping block are fixedly connected with a first screw head, and both ends of the second clamping block are fixedly connected with a second screw head. The outer surfaces of the first screw head and the second screw head are threadedly connected with a fixing cap.

[0011] Furthermore, a limiting strip is slidably connected to the outer surfaces of the first clamping block and the second clamping block, a weight is fixedly connected to the lower surface of the limiting strip, and a sealing block is movably connected to the left side of the limiting strip.

[0012] Furthermore, the inner wall of the limiting strip is provided with a sliding groove, the inner wall of the first locking block is rotatably connected to the second locking block through a cylinder, and a screw is threadedly connected to one side of the limiting strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, this utility model uses the first and second locking blocks to tighten the top of the smoke-proof cloth, fixing it in place. The limiting slide and screws further tighten the cloth. Simultaneously, by adjusting the relative position between the limiting slide and the first locking block, the fixing blocks on both sides approach the walls at the desired fixing position. Rotating the first limiting cylinder moves the second and third screws away from each other, causing the fixing plate to fit tightly against the wall and be pressed in place. Simultaneously rotating the second limiting cylinder moves the first and fourth screws away from each other, further pressing the fixing plate and forming a triangular stable structure. This design prevents damage to the wall, allows for quick installation, and increases the stability of the device.

[0015] 2. In use, this utility model is used to fix the bottom of the smoke-proof cloth by installing the bottom of the smoke-proof cloth between the first and second locking blocks and installing a fixing cover. The first and second locking blocks that hold the smoke-proof cloth are inserted into the sliding groove and a sealing block is inserted to limit and fix the first and second locking blocks, thereby playing the role of weighting and limiting the bottom of the smoke-proof cloth.

A first limiting ring 11 is fixedly connected to one end of the first limiting cylinder 9 away from the first limiting cylinder 9. A first limiting block 12 is rotatably connected to the inner wall of the first limiting ring 11 by bolts. A fixing plate 13 is fixedly connected to one side of the first limiting block 12. A second limiting block 14 is fixedly connected to one side of the fixing plate 13. A second limiting ring 15 is rotatably connected to the inner wall of the second limiting block 14 by bolts. A fourth screw 16 is fixedly connected to the outer surface of the second limiting ring 15. A second limiting cylinder 17 is threadedly connected to the outer surface of the fourth screw 16.

[0029] During operation, the top of the smoke-proof cloth 3 is tightened and fixed by the first locking block 4 and the second locking block 28. The smoke-proof cloth 3 is further tightened by the limiting slide 5 and the screw 29. At the same time, the relative position between the limiting slide 5 and the first locking block 4 is adjusted so that the fixing blocks 7 on both sides are close to the two walls of the desired fixing position. The first limiting cylinder 9 is rotated so that the second screw 8 and the third screw 10 move away from each other, so that the fixing plate 13 is tightly pressed and fixed to the wall. At the same time, the second limiting cylinder 17 is rotated so that the first screw 6 and the fourth screw 16 move away from each other, further pressing the fixing plate 13, forming a triangular stable structure. This structure does not damage the wall, allows for quick installation, and increases the stability of the device.

[0030] Furthermore, the end of the second limiting cylinder 17 away from the fourth screw 16 is threadedly connected to the first screw 6, and the end of the first screw 6 away from the second limiting cylinder 17 is fixedly connected to the third limiting ring 18. A limiting groove 19 is opened on one side of the fixing block 7.

[0031] During operation, the third limiting ring 18 rotates the second limiting cylinder 17 to change the angle of the fixing plate 13, so that the fixing plate 13 can fit tightly against the wall at any angle.

[0032] Furthermore, the inner wall of the limiting groove 19 is rotatably connected to a third limiting ring 18 by bolts, the front side of the smoke-proof cloth 3 is snapped with a first clamping block 21, and the inner wall of the first clamping block 21 is rotatably connected to a second clamping block 27 by a connecting column 25.

[0033] During operation, the connecting column 25 connects the first clamping block 21 and the second clamping block 27, enabling the first clamping block 21 and the second clamping block 27 to clamp the smoke-proof cloth 3.

[0034] Furthermore, both ends of the first clamping block 21 are fixedly connected with a first screw head 22, and both ends of the second clamping block 27 are fixedly connected with a second screw head 26. The outer surfaces of the first screw head 22 and the second screw head 26 are threadedly connected with a fixing cap 23.

[0035] During operation, the fixing cover 23 fixes the first screw head 22 and the second screw head 26, so that the first clamping block 21 and the second clamping block 27 can clamp the smoke-proof cloth 3.

[0036] Furthermore, a limiting strip 20 is slidably connected to the outer surfaces of the first clamping block 21 and the second clamping block 27. A weight block 1 is fixedly connected to the lower surface of the limiting strip 20, and a sealing block 2 is movably connected to the left side of the limiting strip 20.

[0037] During operation, the weight block 1 limits the bottom of the smoke barrier cloth 3 to a certain extent, thereby increasing the working effect.

[0038] Furthermore, the inner wall of the limiting strip 20 is provided with a sliding groove 24, the inner wall of the first locking block 4 is rotatably connected to the second locking block 28 via a cylinder, and a screw 29 is threadedly connected to one side of the limiting strip 5.

[0039] During operation, the screws 29 fix the first locking block 4, the second locking block 28 and the limiting slide 5 to achieve the optimal installation position.

[0040] Working principle: By installing the bottom end of the smoke-proof cloth 3 between the first locking block 4 and the second locking block 28, and installing the fixing cover 23, the bottom end of the smoke-proof cloth 3 is reinforced and fixed. The first locking block 4 and the second locking block 28 that reinforce the smoke-proof cloth 3 are inserted into the slide groove 24, and the sealing block 2 is inserted to limit and fix the first locking block 4 and the second locking block 28, which serves to reinforce and limit the bottom of the smoke-proof cloth 3. Then, the top of the smoke-proof cloth 3 is tightened by the first locking block 4 and the second locking block 28 to fix the smoke-proof cloth 3. The limiting slide strip 5 and the screw 29 are used for fixing and advancing. The smoke-proof cloth 3 is tightened in one step. At the same time, the relative position between the limiting slide bar 5 and the first locking block 4 is adjusted so that the fixing blocks 7 on both sides are close to the two walls of the desired fixing position. The first limiting cylinder 9 is rotated so that the second screw 8 and the third screw 10 move away from each other, so that the fixing plate 13 is tightly pressed and fixed to the wall. At the same time, the second limiting cylinder 17 is rotated so that the first screw 6 and the fourth screw 16 move away from each other to further press the fixing plate 13, forming a triangular stable structure. This has the effect of not damaging the wall, enabling quick installation, and increasing the stability of the device.
