The top of the slide rail connector is fixedly connected to the ceiling, and the bottom is provided with a slide rail. The top of the slide groove connector is provided with a slide groove that mates with the slide rail, and the bottom is provided with a fixing groove that mates with the smoke curtain. The top of the smoke curtain is provided with a first rigid edging, which is inserted into the fixing groove. During installation, the first rigid edging is inserted into the fixing groove from one end, the slide groove is inserted into the slide rail from one end, and finally the top of the slide rail connector is fixedly connected to the ceiling.

[0003] During installation, the smoke curtain only requires the sliding rail connector to be fixedly connected to the ceiling, eliminating the need to connect the angle iron to the smoke curtain, saving installation time and improving work efficiency.

[0004] The technical solution in the prior art has the effect of saving installation time and improving work efficiency. However, the use of a sliding rail structure for connection and installation, especially in large-scale installation operations, requires sliding the vertical walls one by one into the sliding rail, which takes a long time and is still not fast enough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a smoke curtain that solves the problem that using a sliding rail structure for connection and installation, especially in large-scale installation operations, requires sliding the curtains one by one into the sliding rail, resulting in a long sliding time and still not being fast enough.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smoke curtain, including an installation groove, a slot is provided on the bottom surface of the installation groove, a connecting component is engaged inside the installation groove through the slot, a flexible curtain is fixedly connected to the bottom surface of the connecting component, and a counterweight component is fixedly connected to the bottom surface of the flexible curtain.

[0007] The connecting assembly includes a connecting block fixedly connected to the top surface of the flexible vertical wall, and several inclined spring steel plates are fixedly connected at equal intervals from top to bottom on both sides of the connecting block.

[0008] The counterweight assembly includes a counterweight tube fixedly connected to the bottom surface of the flexible vertical wall. One end of the counterweight tube has a threaded inlet, and a sealing cap is threadedly connected to the surface of the threaded inlet. A sealing ring is fitted inside the sealing cap.

[0009] In one specific embodiment, the spring steel plates on both sides of the connecting block are distributed at equal intervals along the vertical height of the connecting block.

[0010] In one specific embodiment, the side of the sealing cap is provided with annular anti-slip texture, and the outer wall of the threaded inlet of the counterweight tube is provided with an external thread that matches the internal thread of the sealing cap.

[0011] In one specific embodiment, the counterweight tube has a through-hole structure inside, and the chamber structure is connected to the outside through a threaded inlet.

[0012] In one specific embodiment, the sealing ring has a trapezoidal cross-section and its outer diameter matches the inner diameter of the sealing cap. The sealing ring is made of fluororubber.

[0013] In one specific embodiment, the inner wall surface of the mounting groove is provided with wavy anti-slip protrusions extending along its length.

[0014] Compared with the prior art, the present invention provides a smoke curtain with the following advantages:

[0015] In the technical solution disclosed in this utility model, the inclined spring steel plates set on both sides of the connecting block in the connecting component are squeezed and contracted when inserted into the installation groove. After entering, they form a snap-fit ​​limiting structure through elastic rebound, so that the flexible vertical wall can be quickly snapped and installed in the vertical direction. Compared with the sliding installation method of the prior art, it saves the tedious operation of sliding in one by one, and is especially suitable for large-area continuous installation scenarios.

[0016] The connecting component of this utility model fixes the top surface of the flexible vertical wall to a connecting block. Several inclined spring steel plates are welded at equal intervals along the vertical height on both sides of the connecting block using a stamping process. The inclination angle of the spring steel plates is 30°-45°, and their free ends extend outward to form an elastic snap-fit ​​part. During installation, the spring steel plate on the top of the connecting block is aligned with the snap-fit ​​opening on the bottom surface of the mounting groove and inserted vertically. The spring steel plate is squeezed against the side wall of the connecting block by the inner wall of the snap-fit ​​opening and contracts. When the connecting block is completely inserted into the mounting groove, the spring steel plate rebounds outward through its own elasticity and unfolds. Its maximum width after unfolding is greater than the width of the snap-fit ​​opening, forming a multi-level snap-fit ​​limiting structure. Attached Figure Description

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4 In one embodiment of this utility model, a smoke curtain includes an installation groove 1, a slot is provided on the bottom surface of the installation groove 1, a connecting component 2 is engaged inside the installation groove 1 through the slot, a flexible curtain 3 is fixedly connected to the bottom surface of the connecting component 2, and a counterweight component 4 is fixedly connected to the bottom surface of the flexible curtain 3.

[0025] The specific problem addressed in this embodiment is that using a slide rail structure for connection and installation, especially in large-scale installation operations, requires sliding the vertical walls one by one into the slide rail, resulting in a long sliding time and still being insufficiently fast. This utility model utilizes inclined spring steel plates 22 on both sides of the connecting block 21 in the connecting component 2. These plates are compressed and contracted when inserted into the installation groove 1, and after entering, they elastically rebound to form a snap-fit ​​limiting structure, enabling the flexible vertical wall 3 to achieve rapid vertical snap-fit ​​installation. Compared to the slide rail sliding installation method in the prior art, this eliminates the tedious operation of sliding in one by one, making it particularly suitable for large-area continuous installation scenarios.

[0026] The connecting component 2 includes a connecting block 21 fixedly connected to the top surface of the flexible vertical wall 3. Several inclined spring steel plates 22 are fixedly connected at equal intervals from top to bottom on both sides of the connecting block 21. In this specific embodiment, the spring steel plates 22 on both sides of the connecting block 21 are distributed at equal intervals along the vertical height of the connecting block 21. The connecting block 21 is fixed to the top surface of the flexible vertical wall 3. Several inclined spring steel plates 22 are welded at equal intervals along the vertical height on both sides of the connecting block 21 using a stamping process. The inclination angle of the spring steel plates 22 is 30°-45°, and their free ends extend outwards to form elastic locking parts. During installation, the spring steel plates 22 on the top of the connecting block 21 are aligned with the locking slots on the bottom surface of the mounting groove 1 and inserted vertically. The spring steel plates 22 are pressed against the side wall of the connecting block 21 by the inner wall of the locking slots of the mounting groove 1 and contract. When the connecting block 21 is fully inserted into the mounting groove 1, the spring steel plates 22 rebound outwards through their own elasticity and unfold. The maximum width after unfolding is greater than the width of the locking slots, forming a multi-level locking and limiting structure.

[0027] In this specific embodiment, the counterweight assembly 4 includes a counterweight tube 41 fixedly connected to the bottom surface of the flexible vertical wall 3. One end of the counterweight tube 41 is provided with a threaded inlet. A sealing cap 42 is threadedly connected to the surface of the threaded inlet. A sealing ring 43 is sleeved inside the sealing cap 42.

[0028] The structure is linked through the counterweight tube 41, the sealing cap 42, and the sealing ring 43: The counterweight tube 41 adopts a through-hole structure, with one end having a threaded inlet formed by machining external threads, which engages with the internal threads on the inner wall of the sealing cap 42. When the sealing cap 42 is screwed, its side ring anti-slip texture provides operating friction, ensuring the stability of the thread engagement during tightening. The sealing ring 43 is made of fluororubber molded into a trapezoidal cross-section structure and embedded in the annular groove inside the sealing cap 42. Its outer diameter is slightly larger than the inner diameter of the sealing cap 42. When the sealing cap 42 is screwed into the threaded inlet of the counterweight tube 41, the sealing ring 43 undergoes elastic deformation due to radial compression, and the trapezoidal cross-section... The inclined surface forms a multi-layer sealing interface with the root of the external thread of the counterweight tube 41 and the inner wall of the sealing cap 42, achieving dynamic sealing through elastic compression. The through-cavity of the counterweight tube 41 allows for on-site filling with gravel or water through the threaded inlet. After filling, the material is evenly distributed in the cavity, avoiding local weight concentration that could cause deformation of the flexible vertical wall 3. The linkage sealing mechanism of the sealing cap 42 and the sealing ring 43 can quickly close the inlet to prevent leakage. In the overall structure, the threaded connection provides a detachable function, the elastic deformation of the sealing ring 43 compensates for the thread meshing gap, and the high temperature resistance of fluororubber adapts to the thermal expansion changes in a fire environment. The three work together to ensure the adjustability of the counterweight, lightweight transportation, and long-term sealing reliability.

[0029] Working principle: During installation, the inclined spring steel plate 22 on the top of the connecting block 21 in the connecting assembly 2 is aligned with the slot on the bottom of the mounting groove 1 and inserted vertically. The spring steel plate 22 is squeezed against the side wall of the connecting block 21 by the inner wall of the mounting groove 1 and contracts. When the connecting block 21 is fully inserted into the mounting groove 1, the spring steel plate 22 rebounds outward due to its own elasticity and unfolds. Its maximum width after unfolding is greater than the width of the slot, forming a multi-level elastic locking limit. At the same time, the wavy anti-slip protrusions on the inner wall of the mounting groove 1 contact the surface of the spring steel plate 22 to generate frictional resistance, preventing the flexible vertical wall 3 from shaking due to airflow disturbance; the distribution structure at the bottom of the flexible vertical wall 3 In component 4, after the counterweight tube 41 is filled with sand or water through the threaded inlet, the sealing cap 42 is tightened and the fluororubber sealing ring 43 inside is compressed, so that the outer diameter of the sealing ring 43, the inner diameter of the sealing cap 42, and the root of the external thread of the counterweight tube 41 form a multi-seal interface to prevent the counterweight material from leaking. The through-cavity structure of the counterweight tube 41 makes the filling material evenly distributed, and the flexible vertical wall 3 is kept vertical by gravity traction. The spring steel plates 22 on both sides of the connecting block 21 are arranged at equal intervals and staggered in the mounting groove 1 to form symmetrical elastic support. Combined with the counterweight of the counterweight tube 41, they jointly resist the impact of external airflow and ensure the overall stability of the smoke curtain.
