Description

Technical Field

[0001] This application relates to the field of smoke curtain technology, and in particular to a fireproof and smoke-proof glass fixed linear smoke curtain. Background Technology

[0002] Glass smoke curtains are smoke-blocking facilities made primarily of glass, typically fire-resistant glass. Their core function is to create a vertical partition through the hanging glass components during a fire, preventing smoke from spreading horizontally within the building and buying time for evacuation and fire rescue. However, during installation, the actual dimensions of the building structure may have construction errors or design changes. Existing smoke curtain frames have fixed dimensions and cannot be adjusted according to the actual installation situation or the size of the glass. This necessitates the customization of frames to meet installation requirements, increasing costs and making them unsuitable for different spaces, resulting in insufficient flexibility. Utility Model Content

[0003] The purpose of this invention is to provide a fireproof and smoke-proof fixed linear smoke curtain by addressing the aforementioned problems.

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

[0005] This application provides a fireproof and smokeproof glass fixed linear smoke curtain, including a profile frame and a side plate frame. The profile frame has a receiving cavity, and connecting bushings are respectively provided on both sides of the receiving cavity. Parts of the connecting bushings extend to the outside of the profile frame and are provided with baffles. A shaft member is installed in the connecting bushing. The side plate frame has a through hole and is sleeved on the shaft member. Parts of the side plate frame are located in the receiving cavity.

[0006] The connecting bushing has a threaded groove, and the shaft has a convex thread that matches the threaded groove. Through the cooperation of the threaded groove and the convex thread, the shaft is threadedly connected to the connecting bushing.

[0007] The side panel frame also has a slot, and a bracket is provided at the bottom of the side panel frame. A base is provided between the two sets of brackets, and the base has a mounting groove. The cooperation between the base and the two sets of side panel frames forms a receiving area for placing glass.

[0008] The rotation of the shaft member within the connecting bushing causes the side plate frame to move closer to or further away from the connecting bushing, thus expanding or shrinking the accommodating area.

[0009] The base has protective components on both sides, including pads located on the outside of the base.

[0010] In one embodiment, the protective component further includes an elastic element, and grooves are provided on both sides of the base. The elastic element is located in the grooves, one end of the elastic element is connected to the groove, and the other end is connected to the pad.

[0011] The elastic element allows the pad to move closer to or further away from the groove.

[0012] The area of ​​the groove is larger than the area of ​​the pad. When the pad is close to the groove, part of the pad is located inside the groove.

[0013] In one embodiment, the bracket has an opening at the bottom and the shaft has an inner hole at the bottom. When the bracket is installed at the bottom of the side plate frame, the opening, the inner hole, and the through hole are aligned.

[0014] The inner hole is provided with an internal thread. When the opening is aligned with the inner hole, the bracket is equipped with a screw rod. The rod passes through the opening and the through hole and is threaded into the inner hole, so that the bracket is fixed on the side plate frame.

[0015] In one embodiment, a magnetic suction plate is provided on the top of the profile frame, and the profile frame has a limiting hole, one end of which extends into the receiving cavity, and the other end extends through the magnetic suction plate to the outside of the profile frame.

[0016] The bottom end face of the retaining pad is provided with a magnetic layer. When the connecting bushing is located in the accommodating cavity, the bottom end face of the retaining pad abuts against the magnetic plate. Through the cooperation of the magnetic layer and the magnetic plate, the retaining pad is magnetically connected to the magnetic plate.

[0017] In one embodiment, several limiting holes are provided and spaced apart along the length direction of the profile frame;

[0018] When the connecting bushing is installed at different limits, the accommodating area expands or shrinks.

[0019] In one embodiment, sealing gaskets are provided on both sides of the mounting groove. When the glass is installed in the mounting groove, the two sets of sealing gaskets abut against the two end faces of the glass, so that the sealing gaskets are located between the glass and the end faces of the mounting groove.

[0020] In one embodiment, a side groove is provided on the side of the side plate frame away from the card slot.

[0021] The advantages or beneficial effects of the above technical solutions include at least the following:

[0022] This application discloses a fixed linear smoke curtain made of fireproof and smoke-proof glass. It comprises two sets of spaced-apart connecting sleeves within a profile frame. The connecting sleeves have threaded grooves, and the shaft members mounted on them have protruding threads, allowing the shaft members to be threadedly connected to the connecting sleeves. Side plate brackets are mounted on the shaft members. Therefore, by rotating the shaft members on the connecting sleeves, the side plate brackets move closer to or further away from the connecting sleeves, thus changing the height position of the side plate brackets. Furthermore, since the bottom of the side plate brackets is supported by a base via a bracket, when both ends of the glass are embedded into the slots provided in the side plate brackets, the bottom of the glass... The glass is clamped and supported around its perimeter by the mounting groove in the base. When the height of the side panel changes, the area that can accommodate the glass also changes accordingly, making it suitable for glass of different sizes and improving installation flexibility. Furthermore, the protective components on both sides of the base can block the impact when the smoke curtain collides, thus buffering the impact and improving the safety of the smoke curtain. Through the cooperation of the connecting bushing and shaft, the installation range can be flexibly adjusted according to the actual situation, solving the problem of the fixed installation range of existing smoke curtains, which leads to installation limitations.

[0047] Reference Figures 1-9 A fireproof and smoke-proof fixed linear smoke curtain includes a profile frame 1 and a side plate frame 2. The profile frame 1 has a receiving cavity 11. Connecting bushings 3 are respectively provided on both sides of the receiving cavity 11. Parts of the connecting bushings 3 extend to the outside of the profile frame 1 and are provided with baffles 31. A shaft member 4 is installed in the connecting bushings 3. The side plate frame 2 has a through hole 21 and is sleeved on the shaft member 4. Parts of the side plate frame 2 are located in the receiving cavity 11. The receiving cavity 11 provides installation space for the side plate frame 2 and the shaft member 4. The symmetrical connecting bushings 3 achieve balanced support for the side plate frames 2 on both sides. The design of the connecting bushings 3 extending to the outside ensures the rotational freedom of the shaft member 4 and forms a physical barrier through the baffles 31 to prevent dust and foreign objects from entering the receiving cavity 11.

[0048] The connecting bushing 3 is provided with a threaded groove 32, and the shaft member 4 is provided with a convex thread 41 that matches the threaded groove 32. Through the cooperation of the threaded groove 32 and the convex thread 41, the shaft member 4 is threadedly connected to the connecting bushing 3. The threaded drive has a self-locking characteristic. When the shaft member 4 rotates to the target position, when the side plate frame 2 is located on the shaft member 4, the rotation of the shaft member 4 can drive the side plate frame 2 to adjust its position and height.

[0049] The side panel frame 2 also has a slot 22, which is used to accommodate the side 14 of the glass. The bottom of the side panel frame 2 is provided with a bracket 5, and a base 6 is provided between the two sets of brackets 5. The base 6 has an installation groove 61. The base 6 and the two sets of side panel frames 2 cooperate to form an area for placing glass. The bracket 5 is used to support the side panel frame 2 and the base 6.

[0050] By rotating the shaft member 4 within the connecting bushing 3, the side panel frame 2 moves closer to or further away from the connecting bushing 3, expanding or shrinking the accommodating area. As the side panel frame 2 rotates with the shaft member 4, its position changes synchronously, and the bracket 5 synchronously drives the base 6 to move, thereby adjusting the range of glass accommodating area. Furthermore, the profile frame 1 has a side 14 with a certain length, ensuring that during the connection between the shaft member 4 and the connecting bushing 3, part of the side panel frame 2 remains within the profile frame 1, thus maintaining a sealed and smoke-proof effect when installing glass of different sizes.

[0051] Protective components 7 are provided on both sides of the base 6. The protective components 7 include a pad 71. The pad 71 is located on the outside of the base 6 and covers the exposed area of ​​the glass edge to prevent the glass corners from being damaged by collision during transportation and installation.

[0052] Based on the above structure, when the connecting bushing 3 is located in the receiving cavity 11 of the profile frame 1, the profile frame 1 is connected to the top of the wall to complete the installation and fixation of the profile frame 1. Then, the shaft member 4 is installed on the connecting bushing 3, so that the protruding thread 41 on the shaft member 4 is threadedly connected to the threaded groove 32 of the connecting bushing 3. Since the side plate frame 2 is sleeved on the shaft member 4 through the through hole 21, the rotation of the shaft member 4 in the connecting bushing 3 can drive the side plate frame 2 to move closer to or away from the connecting bushing 3. Thus, the height position of the side plate frame 2 can be changed according to the size of the glass to be installed. After the adjustment is completed, the glass is placed between the two sets of side plate frames 2. Since the side plate frame 2 has a slot 22 and a bracket 5 is provided at the bottom, the two ends of the glass are embedded in the slot 22, and the bottom part is supported by the bracket 5. A base 6 is also provided between the two sets of brackets 5. When the glass is located between the two sets of slots 22, By embedding the bottom part of the glass into the mounting groove 61 of the base 6, the bottom and sides of the glass can be supported and clamped. Since the rotation of the shaft member 4 in the connecting bushing 3 can adjust the position of the side plate frame 2, different lengths of glass can be installed without changing the width, thus achieving flexibility in installation. In addition, the pad 71 of the protective components 7 on both sides of the base 6 is located on the outside of the base 6. When the smoke curtain is hit, it can contact the pad 71, thereby buffering and blocking the impacting object and preventing the object from directly contacting the glass of the smoke curtain and causing damage to the glass. Through the cooperation of the connecting bushing 3 and the shaft member 4, the height of the side plate frame 2 that supports the glass can be adjusted, improving the adaptability and installation flexibility for different types of glass and solving the problem of the fixed size of the existing smoke curtain, which leads to the limitation of installation.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2, Figure 4 and Figure 10 The protective component 7 also includes an elastic element 72. The base 6 has grooves 62 on both sides, and the elastic element 72 is located in the grooves 62. One end of the elastic element 72 is connected to the groove 62, and the other end is connected to the pad 71. The elastic element 72 adopts the pressure spring or extension spring in the prior art, which has a certain elastic deformation performance. Through the cooperation of the elastic element 72, the pad 71 is moved closer to or away from the groove 62. When the smoke curtain collides, it will first contact the pad 71 in the protective component 7. When the pad 71 is impacted, it will drive the elastic element 72 to undergo elastic deformation, thereby buffering the impact force and preventing the external force from directly contacting the frame of the smoke curtain.

[0054] The area of ​​the groove 62 is larger than the area of ​​the pad 71. When the pad 71 is close to the groove 62, part of the pad 71 is located inside the groove 62. This design, in which part of the pad 71 is located inside the groove 62, can limit the movement of the pad 71 and prevent it from moving excessively and detaching from the groove 62, thus ensuring the stability and reliability of the structure.

[0055] In one embodiment, reference is made to Figure 1 , Figure 6 and Figure 8 The bracket 5 has an opening 51 at its bottom and the shaft member 4 has an inner hole 42 at its bottom. When the bracket 5 is installed on the bottom of the side plate frame 2, the opening 51 is aligned with the inner hole 42 and the through hole 21. The alignment design of the opening 51, the inner hole 42 and the through hole 21 provides a precise path to ensure that the bracket 5 can be accurately installed on the side plate frame 2.

[0056] An internal thread 421 is provided in the inner hole 42. When the opening 51 is aligned with the inner hole 42, the bracket 5 is equipped with a screw rod 8. The rod of the screw rod 8 passes through the opening 51 and the through hole 21 and is threaded into the inner hole 42, so that the bracket 5 is fixed on the side plate frame 2. During the installation process, simply place the bracket 5 in the appropriate position, align the three holes, insert the screw rod 8 and tighten it to complete the fixation. The operation is simple and quick, improving the installation efficiency. The connection between the screw rod 8 and the internal thread 421 can improve stability and reliability, and at the same time prevent the bracket 5 from loosening or falling off due to external forces during use. This fixing method makes the bracket 5 and the side plate frame 2 form a solid integral structure, which can effectively withstand the various forces that the smoke curtain is subjected to during operation. When the smoke curtain needs to be maintained or repaired, simply unscrew the screw rod 8 to easily disassemble the bracket 5, which is convenient and quick and reduces maintenance costs.

[0057] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 7 and Figure 8A magnetic suction plate 12 is provided on the top of the profile frame 1. The profile frame 1 has a limiting hole 13. One end of the limiting hole 13 extends into the receiving cavity 11, and the other end extends through the magnetic suction plate 12 to the outside of the profile frame 1. The setting of the limiting hole 13 provides precise positioning for the installation of the connecting bushing 3 and the retaining pad 31.

[0058] A magnetic layer 311 is provided on the bottom end face of the retaining pad 31. When the connecting sleeve 3 is located in the accommodating cavity 11, the bottom end face of the retaining pad 31 abuts against the magnetic suction plate 12. Through the cooperation of the magnetic layer 311 and the magnetic suction plate 12, the magnetic poles between the magnetic layer 311 and the magnetic suction plate 12 attract each other, so that the retaining pad 31 is magnetically connected to the magnetic suction plate 12. When installing the connecting sleeve 3, it is only necessary to pass the connecting sleeve 3 through the limiting hole 13. When the magnetic layer 311 of the retaining pad 31 approaches the magnetic suction plate 12, the retaining pad 31 will automatically be attracted to the magnetic suction plate 12 under the action of magnetic force. At the same time, the setting of the retaining pad 31 only requires the application of a certain external force to overcome the magnetic force, which makes it easy to remove the connecting sleeve 3, improving the flexibility of installation and disassembly.

[0059] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 5 The limiting holes 13 are provided in several places and are distributed at intervals along the length of the profile frame 1. When the connecting bushing 3 is installed in different limiting positions, the accommodating area expands or shrinks. Users can install the connecting bushing 3 on the limiting holes 13 at different positions according to actual needs. This allows the accommodating area to be expanded or reduced by changing the installation position of the connecting bushing 3 when installing glass components of different sizes, thereby improving the versatility of the smoke curtain. At the same time, the spaced distribution structure facilitates installation and adjustment. Installers can quickly find the appropriate position of the limiting holes 13 according to specific installation requirements without the need for complex measurements and calculations, thus improving installation efficiency.

[0060] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 10 Sealing gaskets 611 are provided on both sides of the mounting groove 61. The sealing gaskets 611 are made of rubber. When the glass is installed in the mounting groove 61, the two sets of sealing gaskets 611 abut against the two end faces of the glass, so that the sealing gaskets 611 are located between the glass and the end faces of the mounting groove 61. The sealing gaskets 611 effectively prevent smoke and flames from leaking through the gap between the mounting groove 61 and the glass. In the event of a fire, smoke and flames will spread through any tiny gap, and the tight fit of the sealing gaskets 611 can form a sealing barrier to ensure the smoke and fire prevention performance of the smoke curtain. At the same time, it can also protect and buffer the glass, reduce the hard contact between the glass and the mounting groove 61, and prevent the glass from breaking due to uneven force.

[0061] In one embodiment, reference is made to Figure 1 and Figure 2 The side panel frame 2 is provided with a side groove 23 on the other side away from the slot 22. The side groove 23 provides more functions and possibilities for the side panel frame 2. It can be used to install other auxiliary components, such as decorative strips and reinforcing ribs. At the same time, the side groove 23 can also be used as a cable tray to arrange wires, signal lines, etc., making the wiring layout more neat and orderly, avoiding the safety hazards caused by exposed wires, and also facilitating the maintenance and replacement of the wiring. In addition, the structural design of the side groove 23 also facilitates the connection of the side panel frame 2 with other components, improving installation efficiency.

[0062] In one embodiment, reference is made to Figure 2 , Figure 3 and Figure 6 The shaft member 4 has a limiting seat 43. When the side plate frame 2 is installed on the shaft member 4, the top of the side plate frame 2 abuts against the limiting seat 43. The limiting seat 43 can play a role in precise limiting and positioning during the installation of the side plate frame 2. When installing the side plate frame 2, after the side plate frame 2 is sleeved on the shaft member 4, it is only necessary to abut the top of the side plate frame 2 against the limiting seat 43 to determine the accurate position of the side plate frame 2 on the shaft member 4, thus avoiding structural instability or functional failure caused by positional deviation during the installation process.

[0063] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0064] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
