Description

Technical Field

[0001] This utility model belongs to the technical field of smoke curtains, and more specifically, it relates to a hanging and detachable smoke curtain. Background Technology

[0002] In public buildings such as shopping malls, office buildings, and commercial streets, smoke curtains are needed to divide smoke-proof zones, prevent the lateral spread of fire smoke, and ensure the unobstructed evacuation routes and safety of people. This ensures the effectiveness of smoke-proof separation and also meets the needs of later inspection and maintenance.

[0003] However, traditional smoke curtains often only have basic smoke-blocking and separation functions, and are mostly fixed by welding or non-removable bolts during installation. They lack a convenient disassembly structure, which means that when it is necessary to inspect the pipelines in the ceiling or replace the smoke curtain, the smoke curtain must be forcibly disassembled, damaging the ceiling or wall structure. This makes the smoke curtain unusable and increases the maintenance cost of traditional devices. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a detachable, hanging smoke curtain to solve the technical problem that traditional devices lack a detachable structure for fixed installation.

[0005] The purpose and effect of this utility model of a hanging, detachable smoke curtain are achieved by the following specific technical means:

[0006] A detachable, wall-mounted smoke curtain includes a suspended ceiling and a wall fixed above the ceiling. A smoke curtain body is provided on one side of the wall. The top of the smoke curtain body passes through the suspended ceiling and is detachably connected to the wall via an installation strip and multiple sets of fixing strips. The installation strip is fitted onto the top of the smoke curtain body. The multiple sets of fixing strips are respectively fixed to the side of the wall near the smoke curtain body by bolts. The multiple sets of fixing strips are detachably connected to the installation strip by multiple sets of buckles. The installation and removal of the smoke curtain body are completed by opening and closing the multiple sets of buckles.

[0007] Ideally, the mounting strip has a groove on one side near the multiple sets of fixing strips, and multiple sets of slots on the other side. Each set of fixing strips has a protrusion and two sets of limiting blocks integrally formed on the side near the mounting strip. The groove is fitted onto the multiple sets of protrusions to form a preliminary hanging, which is detachable.

[0008] Ideally, the buckle is provided with a rotating shaft on the side near the fixing strip, and the two ends of the rotating shaft are respectively set in the horizontal sliding grooves opened by the two sets of limiting blocks to provide guidance for the opening and closing of the buckle; the side of the buckle near the mounting strip is engaged in the slot, and a top rod is slidably provided between the fixing strip and the wall, and the top rod is set vertically.

[0009] Ideally, the top of the top rod is provided with an inclined surface, which is connected to the buckle by a pin. One end of the pin is fixed to the buckle near the mounting strip, and the other end passes through the fixing strip and contacts the inclined surface. A spring is sleeved on the pin. The spring is normally in a compressed state. One end of the spring is fixed to the pin, and the other end is fixed to the fixing strip near the buckle.

[0010] Ideally, a finishing keel is provided between the fixing strip and the wall and the ceiling. The top of the finishing keel is bolted to the wall, and the bottom of the finishing keel is fixed inside the ceiling and connected to the bottom of the top rod by a disassembly bolt. The top of the disassembly bolt is fixed to the bottom of the top rod, and the disassembly bolt passes through the finishing keel and is threaded to the finishing keel.

[0011] Ideally, tightening the mounting bolts drives the top rod to rise vertically, the inclined surface presses against the pin to extend the spring, which in turn causes the buckle to open around the pivot and release its lock with the slot; loosening the mounting bolts causes the top rod to fall vertically, the spring to reset and drive the pin to retract, causing the buckle to engage in the slot, completing the final mounting.

[0012] Ideally, sealant is filled between both sides of the smoke curtain body and the ceiling to reduce the entry of impurities. The mounting strip is fixed to the smoke curtain body by multiple sets of fixing nails, which are spaced apart along the length of the mounting strip.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through the coordinated design of disassembly bolts, top rods, pins, and buckles, allows users to drive the top rod to rise and fall simply by tightening the disassembly bolts, thereby automatically opening and closing the buckles. This eliminates the need for complex tools or violent disassembly, improving the ease of disassembly and assembly of the device. After completing the inspection of pipelines in the ceiling or the maintenance of the smoke curtain, users can complete the hanging and fixing by reversing the operation, making the smoke curtain reusable and reducing additional replacements. This reduces material waste and damage to the building structure, improving the economic practicality and environmental friendliness of the device.

[0015] 2. When using this device, the user can initially position the smoke curtain body by using the groove of the mounting strip and the protrusion of the fixing strip. The horizontal sliding groove of the limiting block provides guidance for the opening and closing of the buckle, thereby realizing the alignment and installation of the smoke curtain body. This improves the installation accuracy and stability of the device. Then, the gap between the smoke curtain body and the ceiling is filled with sealant to reduce the entry of impurities. At the same time, the sealant allows the device to be refilled with sealant when the smoke curtain is reinstalled, ensuring the integrity of the sealing structure and improving the smoke prevention reliability and service life of the device.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a detachable smoke curtain, including a ceiling 1, a wall 2 fixed above the ceiling 1, a smoke curtain body 3 on one side of the wall 2, the top of the smoke curtain body 3 passing through the ceiling 1 and detachably connected to the wall 2 via an installation strip 4 and multiple sets of fixing strips 5, the installation strip 4 being sleeved on the top of the smoke curtain body 3, and the multiple sets of fixing strips 5 being fixed to the side of the wall 2 near the smoke curtain body 3 by bolts, and the multiple sets of fixing strips 5 being detachably connected to the installation strip 4 via multiple sets of buckles 6, the installation and removal of the smoke curtain body 3 being completed by opening and closing the multiple sets of buckles 6.

[0025] Specifically, the ceiling 1 and the wall 2 form the installation reference. The smoke curtain body 3 serves as the smoke-blocking component. Its top penetrates through the ceiling 1 to achieve hanging and fixing with the wall 2, reducing the problem of traditional floor-mounted installation occupying ground space. The installation strip 4 and the smoke curtain body 3 are fitted together to provide a connection base for the two. The fixing strip 5 serves as a transition connection component between the wall 2 and the installation strip 4. The opening and closing of the buckle 6 realizes the closed-loop operation of hanging, locking and disassembly, solving the problem of disassembly difficulties caused by traditional smoke curtains relying on welding or non-removable bolts.

[0026] The mounting strip 4 has a groove 7 on one side near the multiple sets of fixing strips 5, and multiple sets of slots 8 on the other side. Each set of fixing strips 5 has a protrusion 9 and two sets of limiting blocks 10 integrally formed on the side near the mounting strip 4. The groove 7 is fitted onto the multiple sets of protrusions 9 to form a preliminary hanging, and it is detachable.

[0027] Specifically, the interlocking of the groove 7 and the protrusion 9 enables the initial mounting. During installation, simply align the groove 7 of the mounting strip 4 with the protrusion 9 of the fixing strip 5 to complete the temporary positioning of the smoke curtain body 3. This eliminates the need for multiple people to lift and align, improving installation efficiency. This interlocking method also provides detachability, reducing the need for adjustments after initial positioning and providing a stable foundation for the subsequent engagement of the buckle 6.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a rotating shaft 11 is inserted through the side of the buckle 6 near the fixing strip 5. The two ends of the rotating shaft 11 are respectively set in the horizontal sliding grooves opened by the two sets of limiting blocks 10, which provide guidance for the opening and closing of the buckle 6. The side of the buckle 6 near the mounting strip 4 is locked in the slot 8. A top rod 12 is slidably set between the fixing strip 5 and the wall 2. The top rod 12 is set vertically.

[0029] Specifically, the cooperation between the rotating shaft 11 and the horizontal sliding groove of the limiting block 10 limits the horizontal movement trajectory of the buckle 6, reduces the offset and jamming of the buckle 6 during operation, and ensures that it can be engaged or disengaged from the slot 8 of the mounting strip 4. The engagement of the buckle 6 and the slot 8 realizes the final fixation of the smoke curtain body 3, while the vertically set top rod 12 serves as the power transmission component of the buckle 6, providing a stable driving force for the opening and closing of the buckle 6 through its own lifting and lowering.

[0030] The top of the top rod 12 is provided with a slope, which is connected to the buckle 6 through a pin 13. One end of the pin 13 is fixed to the buckle 6 near the mounting strip 4, and the other end passes through the fixing strip 5 and contacts the slope. A spring 14 is sleeved on the pin 13. The spring 14 is normally in a compressed state. One end of the spring 14 is fixed to the pin 13, and the other end is fixed to the fixing strip 5 near the buckle 6.

[0031] Specifically, the inclined structure of the top rod 12 realizes the conversion of vertical force to horizontal force. Under normal conditions, the compressed spring 14 applies pressure to the pin 13 towards the top rod 12, thereby driving the buckle 6 to maintain its tendency to fit against the mounting strip 4, ensuring that the buckle 6 and the slot 8 are in a stable engagement state, reducing the possibility of the buckle 6 loosening due to vibration and other factors during use. This elastic pre-tightening structure also provides convenience for disassembly. The buckle 6 can be driven to open simply by breaking the balance state through the top rod 12.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 3 As shown, a finishing keel 15 is provided between the fixing strip 5, the wall 2 and the ceiling 1. The top of the finishing keel 15 is bolted to the wall 2, and the bottom of the finishing keel 15 is fixed inside the ceiling 1. It is connected to the bottom of the top rod 12 by a disassembly bolt 16. The top of the disassembly bolt 16 is fixed to the bottom of the top rod 12. The disassembly bolt 16 passes through the finishing keel 15 and is threadedly connected to the finishing keel 15.

[0033] Specifically, the closing keel 15 provides structural support. Its fixed connection with the wall 2 and the ceiling 1 provides an installation carrier for the top rod 12 and the disassembly bolt 16. At the same time, it covers the gap between the transmission components such as the fixing strip 5 and the top rod 12 and the ceiling 1, improving the overall integrity of the device. The threaded engagement between the disassembly bolt 16 and the closing keel 15 allows the user to control the raising and lowering of the top rod 12 by rotation. The operation is convenient and the force transmission is stable, reducing the possibility of jamming or deviation during the raising and lowering of the top rod 12.

[0034] Tightening the disassembly bolt 16 drives the top rod 12 to rise vertically, and the inclined surface presses the pin 13 to extend the spring 14, which in turn drives the buckle 6 to open around the rotating shaft 11, releasing the lock with the slot 8; loosening the disassembly bolt 16 causes the top rod 12 to fall vertically, the spring 14 to reset and drive the pin 13 to retract, causing the buckle 6 to snap into the slot 8, completing the final mounting.

[0035] Specifically, this paragraph clarifies the complete operational logic for disassembling and mounting the device. During disassembly, tightening the disassembly bolt 16 causes it to move upward along the threaded hole of the constricting keel 15, simultaneously pushing the top rod 12 upward. The inclined surface of the top rod 12 presses the pin 13, moving it away from the top rod 12. The spring 14 extends accordingly, and the pin 13 drives the buckle 6 to open around the rotating shaft 11, disengaging from the slot 8 to unlock. During mounting, loosening the disassembly bolt 16 causes the top rod 12 to descend under gravity. The spring 14 returns to its compressed state and pushes the pin 13 back, causing the buckle 6 to re-engage in the slot 8 to complete the locking. The entire process can be achieved by simply operating the disassembly bolt 16, reducing the use of complex labor and improving the practicality of the device.

[0036] The space between the smoke curtain body 3 and the ceiling 1 on both sides is filled with sealant 17 to reduce the entry of impurities. The mounting strip 4 is fixed to the smoke curtain body 3 by multiple sets of fixing nails 18, which are spaced apart along the length of the mounting strip 4.

[0037] Specifically, the sealant 17 fills the gap between the smoke curtain body 3 and the ceiling 1, which can reduce the entry of impurities into the ceiling and contaminate the transmission components, while improving the smoke-blocking sealing performance of the device. At the same time, the filling of the sealant 17 allows the device to ensure the integrity of the sealing structure when the smoke curtain body 3 is reinstalled by refilling the sealant 17, thus improving the smoke-proof reliability of the device. The fixing nails 18 are spaced along the length of the mounting strip 4, so that the fixing force between the mounting strip 4 and the smoke curtain body 3 is evenly distributed, reducing the deformation of the mounting strip 4 caused by excessive local stress and ensuring connection stability.

[0038] The specific usage and function of this embodiment are as follows:

[0039] During actual installation, firstly, multiple sets of fixing strips 5 are fixed to the preset positions on the wall 2 with bolts, ensuring that the protrusions 9 of the fixing strips 5 face the same direction and are at the same horizontal height. Then, the top of the finishing keel 15 is bolted to the wall 2 and the bottom is fixed in the ceiling 1 to complete the basic frame construction.

[0040] Next, the mounting strip 4 is fixed to the top of the smoke curtain body 3 by multiple sets of fixing nails 18. The fixing nails 18 need to be evenly distributed along the length of the mounting strip 4 to ensure that the mounting strip 4 and the smoke curtain body 3 are firmly connected without loosening.

[0041] Next, pass the top of the smoke curtain body 3 through the ceiling 1, align the groove 7 of the mounting strip 4 with the protrusion 9 of the fixing strip 5, and put it on to achieve initial hanging and positioning. At this time, the smoke curtain body 3 will naturally droop under its own weight. Then, check whether the buckle 6 corresponds to the position of the slot 8 of the mounting strip 4. If there is a deviation, the position of the smoke curtain body 3 can be slightly adjusted to ensure that the buckle 6 can be smoothly inserted into the slot 8.

[0042] Finally, loosen the disassembly bolts 16 at the bottom of the closing keel 15. The top rod 12 descends vertically under the restoring force of the spring 14, causing the pin 13 to retract, so that the buckle 6 rotates around the pivot 11 and engages in the slot 8, completing the final installation of the smoke curtain body 3. Then, fill the gap between the two sides of the smoke curtain body 3 and the ceiling 1 with sealant 17, and it can be put into use. When disassembly is required, simply tighten the disassembly bolts 16. The top rod 12 rises and presses the pin 13 through the inclined surface, causing the spring 14 to extend and drive the buckle 6 to open and disengage from the slot 8. Then, separate the groove 7 of the mounting strip 4 from the protrusion 9 of the fixing strip 5, and the smoke curtain body 3 can be removed as a whole. The whole process is simple to operate and will not damage the structure of the ceiling 1 or the wall 2, ensuring the reuse of the smoke curtain body 3.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
