Description

Technical Field

[0001] This utility model relates to the field of fire-resistant window technology, specifically to a fire-resistant window structure that is easy to install. Background Technology

[0002] Fire-resistant windows are windows that can meet fire integrity requirements for a specified time. These windows are usually made of specific materials and designed to ensure a certain fire resistance time in a fire, primarily used to prevent the spread of fire and provide valuable time for escape and rescue.

[0003] Existing fire-resistant windows allow for glass removal and installation. However, the close proximity of the glass edges to the frame and the lack of effective stress points make the disassembly process extremely inconvenient. Furthermore, the absence of a restraining mechanism after the removal of the fixing components makes the glass prone to sudden detachment due to stress changes, posing a risk of breakage and safety hazards. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-resistant window structure that is easy to install, solving the problems mentioned in the background art, such as the sharp edges of the glass being close to the frame of the fire-resistant window, making it inconvenient to disassemble, and the possibility of it suddenly falling off during the disassembly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-resistant window structure that is easy to install, comprising a limiting block and an adjusting block. The side wall of the adjusting block is provided with a lifting groove, and a lifting block is vertically slidably connected to the inner side of the lifting groove. A lifting block is fixedly connected to the outer side wall of the lifting block, and a return spring is fixedly connected between the lifting block and the inner top end of the lifting groove. A crossbar is fixedly connected to the left side wall of the limiting block, and a push block is fixedly connected to the surface of the lifting block facing the crossbar.

[0006] In this technical solution, the glass can be directly placed into the main frame during installation without the need for deliberate positioning. The limiting blocks can prevent the glass from suddenly detaching during disassembly. At the same time, the lifting blocks can assist in lifting the glass for easy disassembly, improving the convenience and practicality of the device.

[0007] Preferably, a compression spring is fixedly connected between the limiting block and the inner wall of the extrusion groove, the limiting block is slidably connected to the extrusion groove, a side groove is provided on the inner side of the main frame on the left side of the extrusion groove, and the crossbar is located on the inner side of the side groove.

[0008] In this technical solution, the limiting block has the ability to extend and retract. It retracts into the extrusion groove when the glass is placed and pops out of the extrusion groove after the glass is placed, thus limiting the glass.

[0009] Preferably, the main frame has an extrusion groove at the center of the upper and lower inner sidewalls, a side groove at the interior of the upper and lower sides, an adjustment groove at the left edge of the surface of the main frame, and a support block fixedly connected to the center of the left and right inner sidewalls of the adjustment groove.

[0010] In this technical solution, the side groove mainly provides space for the crossbar to move, making it convenient for the push block to push the crossbar and allow the limit block to retract back into the extrusion groove.

[0011] Preferably, a bidirectional lead screw is rotatably connected between the upper and lower inner walls of the adjusting groove. A driven bevel gear is fixedly sleeved on the surface of the bidirectional lead screw. The driven bevel gear meshes with the driving bevel gear. The driving bevel gear is fixedly connected to the bottom end of the transmission rod. The transmission rod passes through the surface of the support block and is rotatably connected to the support block through a bearing seat.

[0012] In this technical solution, the transmission rod drives the active bevel gear and the driven bevel gear to rotate, thereby causing the bidirectional lead screw to rotate and adjust the position of the adjusting blocks at both ends.

[0013] Preferably, the surface of the bidirectional lead screw has two adjusting blocks that pass through it and are threadedly connected to the adjusting blocks, and the two ends of the adjusting groove are respectively connected to the upper and lower side grooves.

[0014] In this technical solution, the adjusting block moves to push the crossbar, causing the limiting block to retract into the extrusion groove, which facilitates the installation and removal of the glass.

[0015] Preferably, the upper right side wall of the adjusting groove is provided with an inclined groove, the lifting block is located inside the inclined groove and is slidably connected along the inclined groove, the inclined groove is inclined, and the glass is lifted up during the process of the lifting block sliding along the inclined groove, so that the edge of the glass is lifted out, which is convenient for handling.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model utilizes the synergistic effect of a limiting block and a compression spring. During glass installation, the limiting block retracts and pops back up after the glass is in place, forming a stable limiting position. During disassembly, the adjusting block drives the push block to link with the crossbar, allowing the limiting block to retract smoothly into the compression groove. This prevents the glass from breaking due to unrestrained detachment throughout the process, significantly improving the safety of the disassembly and assembly process.

[0018] 2. This utility model sets up a lifting groove and a lifting block on the adjusting block. When the push block on the adjusting block pushes the crossbar, the lifting block on the side wall of the lifting block will slide along the inclined groove. During the sliding process, the glass in the main frame will be lifted, so that the edge of the glass is raised, which is convenient for handling and improves the disassembly efficiency of the device.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0027] A fire-resistant window structure that is easy to install, see [link / reference]. Figures 1 to 5 The device includes a limiting block 301 and an adjusting block 7. The side wall of the adjusting block 7 has a lifting groove 702. The inner side of the lifting groove 702 is vertically slidably connected to a lifting block 703. The outer side wall of the lifting block 703 is fixedly connected to a lifting block 704. A return spring 705 is fixedly connected between the lifting block 704 and the inner top of the lifting groove 702. The upper end of the right side wall of the adjusting groove 5 has an inclined groove 8. The lifting block 704 is located inside the inclined groove 8 and is slidably connected along the inclined groove 8. When the adjusting block 7 moves towards the edge of the adjusting groove 5, the lifting block 703 will slide along the lifting groove 702, and the lifting block 704 will slide along the inclined groove 8. During the sliding process, the glass will be lifted, making the glass easier to handle.

[0028] Specifically, the top of the main frame 1 is connected to the sub-frame 2 by a hinge. When the sub-frame 2 is closed, bolts can be screwed into the bolt holes on its surface to complete the fixation. The upper and lower inner sidewalls of the main frame 1 are provided with extrusion grooves 3. The upper and lower sides of the main frame 1 are provided with side grooves 4. The left edge of the surface of the main frame 1 is provided with an adjustment groove 5. The left and right inner sidewalls of the adjustment groove 5 are fixedly connected with support blocks 10.

[0029] It should be noted that after the sub-frame 2 is closed, the limiting block 301 will retract into the extrusion groove 3 due to the compression of the sub-frame 2. At this time, the sub-frame 2 will replace the limiting block 301 to limit and protect the glass. When the glass is placed inside the main frame 1 and close to the inner wall of the main frame 1, there is a certain gap between the limiting block 301 and the surface of the glass. This is only to avoid the limiting block 301 scratching the glass surface and to facilitate the lifting of the glass.

[0030] It should be noted that during the process of the adjusting block 7 pushing the crossbar 302 and sliding the lifting block along the inclined groove 8, since the lifting block 704 is a certain distance from the bottom surface of the glass, and there is also a certain gap between the limiting block 301 and the glass, when the lifting block 704 contacts the glass and pushes the glass, the limiting block 301 has already retracted into the pressing groove 3. Therefore, it is avoided that the lifting block 704 is blocked by the limiting block 301 and gets stuck, so that the glass can be lifted normally.

[0031] Specifically, a bidirectional lead screw 6 is rotatably connected between the upper and lower inner walls of the adjusting groove 5. Two adjusting blocks 7 pass through the surface of the bidirectional lead screw 6 and are threadedly connected to the adjusting blocks 7. The two ends of the adjusting groove 5 are respectively connected to the upper and lower side grooves 4. After the bidirectional lead screw 6 rotates, the adjusting blocks 7 on both sides will move towards their respective side grooves 4. Since the adjusting groove 5 is connected to the side grooves 4, the push block 701 can directly enter the side groove 4 and push the crossbar 302 to move, so that the limiting block 301 retracts into the extrusion groove 3.

[0032] Furthermore, such as Figure 4 As shown, a driven bevel gear 601 is fixedly sleeved on the surface of the bidirectional lead screw 6. The driven bevel gear 601 meshes with the driving bevel gear 901. The driving bevel gear 901 is fixedly connected to the bottom end of the transmission rod 9. The transmission rod 9 passes through the surface of the support block 10 and is rotatably connected to the support block 10 through the bearing seat. The outer surface of the transmission rod 9 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the support block 10 to prevent it from falling off. When the transmission rod 9 is manually rotated, the driving bevel gear 901 at the bottom of the transmission rod 9 drives the driven bevel gear 601 and the bidirectional lead screw 6 to rotate, thereby moving the adjusting blocks 7 on both sides toward the side groove 4. At the same time, the limiting block 301 is stored and the glass is lifted, which improves the convenience and practicality of the device.

[0033] It is worth noting that, such as Figure 3 As shown, a compression spring 303 is fixedly connected between the limiting block 301 and the inner wall of the compression groove 3. The limiting block 301 is slidably connected to the compression groove 3. During the glass insertion process, the limiting block 301 pushes the compression spring 303 and retracts into the compression groove 3. After the glass has completely passed through, the limiting block 301 is pushed out of the compression groove 3 again by the compression spring 303. A side groove 4 is opened on the inner side of the main frame 1 on the left side of the compression groove 3. The crossbar 302 is located inside the side groove 4. The crossbar 302 is fixedly connected to the left side wall of the limiting block 301. A push block 701 is fixedly connected to the surface of the lifting block 704 facing the crossbar 302. The push block 701 pushes the crossbar 302 to slide in the side groove 4, thereby making the limiting block 301 slide, releasing the limitation on the glass, and facilitating the removal of the glass.
