Abstract
Description
Technical Field
[0001] This utility model relates to the field of smoke curtain technology, and more particularly to a fixed smoke curtain. Background Technology
[0002] Smoke curtains play a vital role in various public places, especially in densely populated areas such as office buildings and hotels. Their main function is to separate smoke from the ceiling during a fire, allowing the smoke extraction system to function more effectively and ensuring people's safety. Fixed smoke curtains are the most widely used type in practice.
[0003] However, traditional fixed smoke curtains have some shortcomings during installation. Typically, they are installed using multiple bolts and clamps, requiring installers to use specific tools to secure each bolt to the building structure. This process is time-consuming and labor-intensive, and also presents difficulties for later maintenance and replacement. To address these shortcomings, a new type of fixed smoke curtain is proposed. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fixed smoke curtain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fixed smoke curtain includes a hanging frame, a mounting bracket, and a hanging body. The hanging frame has a mounting groove corresponding to the mounting bracket. The inner wall of the mounting groove has a movable groove. A sliding rod is provided in the movable groove. A limiting bracket is slidably fitted on the sliding rod through an elastic mechanism. A rotating wheel is provided on the limiting bracket through a connecting frame. The inner wall of the mounting groove has a rotating opening. The bottom wall of the mounting groove has an upper top groove. A contact block is provided in the upper top groove through an upper top mechanism. The mounting bracket has a contact groove. The mounting bracket and the hanging body are connected by a hook-and-connect mechanism.
[0007] Preferably, the elastic mechanism includes an upper spring sleeved on the outside of the slide bar, with both ends of the upper spring elastically connected to the inner wall of the movable groove and the outer wall of the limiting frame, respectively.
[0008] Preferably, the upper lifting mechanism includes a lower spring disposed in the upper lifting groove, and the two ends of the lower spring are elastically connected to the outer wall of the contact block and the inner wall of the upper lifting groove, respectively.
[0009] Preferably, the hanging mechanism includes a hanging block disposed on the mounting frame, and the hanging body is provided with a hanging hole corresponding to the hanging block.
[0010] Preferably, the mounting bracket is provided with an inclined surface, and the limiting bracket is also provided with an inclined surface.
[0011] Preferably, a protective frame is installed on the hanging body, and the protective frame is provided with a support groove.
[0012] The beneficial effects of this utility model are:
[0013] 1. The T-shaped vertical cross-section of the mounting bracket and mounting slot allows the mounting bracket to move laterally only to be assembled and disassembled with the mounting slot, simplifying operation. Simultaneously, the inclined surfaces on the mounting bracket and the limiting bracket engage, allowing for direct lateral movement and compression of the limiting bracket during installation, enabling smooth entry into the mounting slot without complex installation steps.
[0014] 2. After the mounting bracket enters the mounting slot, the limiting bracket descends under the action of the upper spring, thereby limiting both ends of the mounting bracket and preventing it from moving laterally and disengaging from the mounting slot, thus ensuring the stability of the installation.
[0015] 3. The contact block inside the mounting slot is positioned within the contact slot of the mounting bracket under the action of the spring, further ensuring the horizontal stability of the mounting bracket when it is placed in the mounting slot.
[0016] 4. When it is necessary to disassemble the hanging body, grasp the lifting groove part on the protective frame with your palm and push the hanging body and mounting bracket upwards. The mounting bracket rises and pushes the rotating wheel, causing the limit bracket to move upwards and retract into the movable groove at the same time, losing the limit on both ends of the mounting bracket. Then the mounting bracket can be moved horizontally to be removed from either end of the mounting groove to complete the disassembly. The operation is convenient and quick.
[0017] 5. A protective frame is installed on the hanging body to protect the exposed edges of the hanging body and extend its service life.
[0018] 6. The lifting groove on the protective frame makes it easy to grip with the palm, thus smoothly lifting the hanging body and mounting bracket and other components, improving the convenience of operation. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-3 A fixed smoke curtain includes a hanging frame 1, a mounting frame 3, and a hanging body 4. The hanging frame 1 is provided with a mounting groove 2 corresponding to the mounting frame 3. The inner wall of the mounting groove 2 is provided with a movable groove 11. A sliding rod 12 is provided in the movable groove 11. A limiting frame 8 is slidably sleeved on the sliding rod 12 through an elastic mechanism. A rotating wheel 15 is provided on the limiting frame 8 through a connecting frame 14. The inner wall of the mounting groove 2 is provided with a rotating opening 16. The bottom wall of the mounting groove 2 is provided with an upper top groove 17. A contact block 18 is provided in the upper top groove 17 through an upper top mechanism. The mounting frame 3 is provided with a contact groove 9. The mounting frame 3 and the hanging body 4 are connected by a hanging mechanism.
[0025] The elastic mechanism includes an upper spring 13 sleeved on the outside of the slide rod 12. The two ends of the upper spring 13 are elastically connected to the inner wall of the movable groove 11 and the outer wall of the limiting frame 8, respectively. The upper spring 13 realizes the downward pressing operation of the limiting frame 8. When the mounting frame 3 is installed in the mounting groove 2, the two limiting frames 8 limit the two ends of the mounting frame 3, thereby preventing it from moving laterally out of the mounting groove 2.
[0026] As shown in the figure, both the vertical cross-section of the mounting slot 2 and the mounting bracket 3 are T-shaped, so the mounting bracket 3 can only move laterally to complete the assembly and disassembly with the mounting slot 2.
[0027] The upper lifting mechanism includes a lower spring 19 disposed within the upper lifting groove 17. The two ends of the lower spring 19 are elastically connected to the outer wall of the contact block 18 and the inner wall of the upper lifting groove 17, respectively. The lower spring 19 enables the contact block 18 to be lifted. When the mounting bracket 3 is installed in the mounting groove 2, the contact block 18 is located within the contact groove 9. Therefore, to a certain extent, the stability of the mounting bracket 3 when placed in the mounting groove 2 can be guaranteed.
[0028] The mounting mechanism includes a mounting block 6 mounted on the mounting frame 3, and a mounting hole 10 corresponding to the mounting block 6 on the hanging body 4. The horizontal part of the mounting block 6 is located within the mounting hole 10, which can ensure the stability of the hanging body 4 when it is installed on the mounting frame 3. The mounting block 6 is mainly composed of two vertical plates and a horizontal axis, which is the horizontal part of the mounting block 6.
[0029] The mounting bracket 3 has an inclined surface, and the limiting bracket 8 also has an inclined surface. The above-mentioned inclined surface ensures that when the mounting bracket 3 is on either side of the mounting slot 2, it can move laterally to compress the limiting bracket 8 and make it rise, so as to smoothly enter the mounting slot 2 for installation.
[0030] A protective frame 5 is installed on the hanging body 4, and the protective frame 5 has a support groove 7. The protective frame 5 can protect the exposed edge of the hanging body 4, and the support groove 7 makes it easy for the cane to grip, so as to smoothly lift the hanging body 4 and the mounting bracket 3 and other components.
[0031] In use, the hanging body 4 is installed by the hanging block 6 and the mounting frame 3. The hoisting frame 1 can be hoisted and installed on the top of the wall. The mounting frame 3 can move laterally from any side of the mounting groove 2 to enter the mounting groove 2. First, the inclined surface on the mounting frame 3 cooperates with the inclined surface of the limiting frame 8 to push the limiting frame 8 up so that it does not obstruct the lateral movement of the mounting frame 3. Then, after the mounting frame 3 enters the mounting groove 2, the limiting frame 8 descends under the action of the upper spring 13 to realize the limiting of both ends of the mounting frame 3, which can prevent the mounting frame 3 from moving laterally and separating from the mounting groove 2. At this time, there is a distance between the upper end face of the mounting frame 3 and the rotating wheel 15, and the bottom wall of the mounting frame 3 contacts the inner bottom wall of the mounting groove 2. The contact block 18 is in the corresponding contact groove 9 to ensure that the mounting frame 3 is horizontally stable in the mounting groove 2.
[0032] When it is necessary to disassemble the hanging body 4, grasp the upper groove 17 on the protective frame 5 with your palm, and then lift the hanging body 4 and the mounting bracket 3. The mounting bracket 3 rises in the mounting groove 2 and lifts the rotating wheel 15. As the rotating wheel 15 is lifted, the limiting bracket 8 will also move upwards simultaneously. At this time, the limiting bracket 8 retracts into the movable groove 11 and loses the limiting at both ends of the mounting bracket 3. Then, maintain this height and move the mounting bracket 3 horizontally so that it can be moved out from either end of the mounting groove 2 to complete the disassembly.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
