[0002] Smoke curtains are passive fire-resistant partitions used in buildings. Their main function is to limit the spread of smoke and flames during a fire, providing time and space for evacuation and fire rescue. Existing flexible smoke curtains are often fixed in a way that prevents them from being removed, to ensure their stability after installation. However, over time, the smoke curtain may lose its original performance due to material aging and other reasons, requiring replacement. In such cases, the entire smoke curtain system needs to be replaced, not just the fabric, leading to higher costs. Utility Model Content

[0003] The purpose of this invention is to provide an installation and fixing device for smoke curtains in order to solve the above-mentioned problems.

[0004] The technical solution of this application is achieved as follows:

[0019] In one embodiment, mounting holes are provided around the top perimeter of the mounting plate.

[0020] The advantages or beneficial effects of the above technical solutions include at least the following:

[0021] This application discloses an installation and fixing device for a smoke curtain. By pressing a support plate in an elastic clamping assembly, the support plate is brought close to the bottom of the receiving groove. Since the support plate is connected to a guide rod with a bearing seat, pressing the support plate moves the bearing seat away from the limiting protrusions in the mounting base, and one end of the smoke curtain passes through the clamping opening in the bearing seat. Then, by resetting the support plate away from the bottom of the receiving groove, the bearing seat moves the smoke curtain into the limiting area formed by two sets of limiting protrusions, and the end face of the limiting protrusions abuts against the end face of the smoke curtain. At the same time, the bottom frame is installed on the bottom of the smoke curtain, thus completing the installation of the smoke curtain. When disassembly is required, pressing the support plate again allows the smoke curtain to be pulled out. The elastic clamping assembly improves the convenience of installing the smoke curtain on the mounting base and solves the problem that existing smoke curtains are fixed during installation and cannot replace the smoke curtain as needed.

[0040] Reference Figure 1-Figure 4 An installation and fixing device for a smoke curtain includes a mounting base 1, a smoke curtain 2, and an elastic clamping assembly 3. The mounting base 1 has a cavity 11. When the smoke curtain 2 is installed in the mounting base 1, it is located in the cavity 11. The top of the mounting base 1 is provided with a mounting plate 12. The top of the mounting plate 12 is provided with mounting holes 122 around its perimeter. The mounting plate 12 is used to connect to the ceiling and is fixed through the mounting holes 122. The mounting plate 12 has a receiving groove 121 that extends into the mounting base 1. The elastic clamping assembly 3 is disposed in the receiving groove 121.

[0041] The elastic clamping assembly 3 includes a support plate 31, a guide rod 32, and a bearing seat 33. The support plate 31 is located in the receiving groove 121 and is connected to the guide rod 32. One end of the guide rod 32 extends into the cavity 11 and is connected to the bearing seat 33. The bearing seat 33 has a clamping opening for accommodating the smoke-proof cloth 2 to pass through. By changing the position of the support plate 31, the position of the bearing seat 33 can be changed synchronously.

[0042] Limiting protrusions 13 are provided on both sides of the interior of the mounting base 1. A limiting area is formed between the two sets of limiting protrusions 13. With the cooperation of the support plate 31 and the guide rod 32, when the support plate 31 is close to or away from the bottom of the receiving groove 121, the bearing base 33 drives the smoke baffle 2 away from or within the limiting area. When the smoke baffle 2 is within the limiting area, the outer side of the smoke baffle 2 abuts against the end face of the limiting protrusion 13.

[0043] The bottom of the smoke shield 2 is equipped with a bottom frame 4, which is made of rigid metal and can support the smoke shield 2.

[0044] Based on the above structure, by pressing the support plate 31, the position of the bearing seat 33 is changed with the cooperation of the guide rod 32, so that the bearing seat 33 is away from the limiting area formed by the two sets of limiting protrusions 13. Then, one end of the smoke-blocking cloth 2 is installed in the mounting base 1 and passes through the clamping opening on the bearing seat 33. Then, the support plate 31 is reset, so that the guide rod 32 drives the bearing seat 33 to move between the two sets of limiting protrusions 13. During the movement, the bearing seat 33 drives the smoke-blocking cloth 2 to move synchronously, so that the smoke-blocking cloth 2... The outer side of the smoke curtain 2 abuts against the limiting protrusion 13, thereby limiting the smoke curtain 2. The mounting base 1 is installed on the top through the support plate 31. When the smoke curtain 2 needs to be replaced, the support plate 31 and the guide rod 32 cooperate to move the bearing seat 33 away from the limiting protrusion 13, thereby pulling out the smoke curtain 2. The elastic clamping component 3 allows for flexible installation or removal of the smoke curtain 2, solving the problem that the smoke curtain 2 cannot be replaced after installation in existing smoke curtains, and only the entire smoke curtain can be replaced.

[0045] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 It also includes a fastening assembly 5, which includes a snap fastener 51 and a female snap fastener 52. The bottom sides of the mounting base 1 are provided with sliding grooves 14. The snap fastener 51 and the female snap fastener 52 are respectively movably disposed in the sliding grooves 14 on both sides. The moving arrangement can improve the flexibility of use of the snap fastener 51 and the female snap fastener 52.

[0046] The slide groove 14 has several through holes 141 penetrating the mounting base 1. These through holes 141 are spaced apart along the length of the slide groove 14. The arrangement of these through holes 141 allows for fastening of the smoke-blocking cloth 2 at different positions. The fastening part 51 has a shaft 511, and the female fastening part 52 has a recess 521. When the smoke-blocking cloth 2 is located on the bearing base 33, one end of the shaft 511 passes through the through hole 141 and the smoke-blocking cloth 2 and is embedded in the recess 521. This further improves the installation of the smoke-blocking cloth 2 on the mounting base 33. The stability of the seat 1 is ensured when the smoke shield 2 is positioned between the two sets of limiting protrusions 13 with the cooperation of the bearing seat 33. By installing the fastener 51 and the female fastener 52 into the sliding grooves 14 on both sides, the fastener 51 and the female fastener 52 are positioned on both sides of the smoke shield 2. When the shaft 511 of the fastener 51 passes through the through hole 141 and through the smoke shield 2 and the recess 521 of the female fastener 52, the shaft 511 can support and limit the smoke shield 2, preventing the smoke shield 2 from falling off the mounting seat 1.

[0047] A magnetic layer 5111 is provided at the bottom of the shaft 511, and a magnetic block 5211 is provided in the recess 521. Through the cooperation of the magnetic layer 5111 and the magnetic block 5211, when the shaft 511 is located in the recess 521, the shaft 511 and the recess 521 are magnetically connected. The magnetic connection allows the shaft 511 to be quickly installed in the recess 521 and prevents it from falling out of the recess 521 due to shaking.

[0048] In one embodiment, reference is made to Figures 2-4 The elastic clamping assembly 3 also includes an elastic element 34. One end of the elastic element 34 is connected to the bottom of the receiving groove 121, and the other end is connected to the support plate 31. The elastic element 34 is a telescopic spring or a compression spring in the prior art, which has a certain elastic deformation effect.

[0049] With the cooperation of the elastic element 34 and the guide rod 32, when the elastic element 34 is not in a compressed state, the top end face of the support plate 31 is parallel to the top end face of the support plate 31. Several elastic elements 34 are provided and distributed at intervals along the length direction of the support plate 31. The arrangement of several elastic elements 34 can support the support plate 31. When the support plate 31 is pressed, the elastic element 34 will be compressed. When the pressure applied to the support plate 31 is released, the elastic element 34 will reset, thereby driving the support plate 31 to change position, thereby further improving the ease of use of the elastic clamping assembly 3.

[0050] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4The limiting protrusion 13 is provided with a groove 131. Several grooves 131 are provided and are distributed at intervals along the length direction of the limiting protrusion 13. Several grooves 131 form anti-slip texture on the limiting protrusion 13. The setting of several grooves 131 can increase the friction when the limiting protrusion 13 contacts the smoke shield 2, so that the smoke shield 2 is not easy to slip when it is located on the limiting protrusion 13, thus enhancing the stability of the smoke shield 2.

[0051] In one embodiment, reference is made to Figure 1 and Figure 7 Magnetic blocks 41 are provided on both sides of the bottom frame 4. When two sets of smoke curtains are adjacent, the smoke curtains can be connected to each other by mutual attraction between the magnetic blocks 41.

[0052] In one embodiment, reference is made to Figure 2 Several guide rods 32 are provided, and the guide rods 32 are distributed at intervals along the length direction of the support plate 31. The guide rods 32 and the elastic element 34 are staggered. The guide rods 32 can guide the support plate 31 when it moves, and the arrangement of several guide rods 32 can improve the stability of the support plate 31 when it moves.
