DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0032] Figure 1-11 The best embodiment of the present invention is shown below in conjunction with the attached Figure 1-11 The present invention is further described.

[0033] A novel detachable fireproof window device comprises a window frame 1 and a glass 2, both of which are made of fireproof materials. The glass 2 is installed in the middle of the window frame 1. The window frame 1 comprises a crossbar 101 and a longitudinal bar 102. There are two crossbars 101 and two longitudinal bars 102, and the two crossbars 101 and the longitudinal bars 102 are symmetrically distributed. A clamping assembly is connected between the crossbar 101 and the longitudinal bar 102, and the crossbar 101 and the longitudinal bar 102 are connected in a rectangular manner and can be disassembled end to end through the clamping assembly, that is, the window frame 1 can be disassembled. The glass 2 is equipped with a limit block 3, which is slidably installed on the side of the longitudinal bar 102 close to the middle of the window frame 1, and after the glass 2 is placed in the middle of the window frame 1, the limit block 3 can automatically resist the glass 2, and a driving assembly is installed on the side of the longitudinal bar 102, and the limit block 3 is driven to slide and the clamping assembly is operated through the driving assembly.

[0034] Both the horizontal bar 101 and the vertical bar 102 are equipped with a pressure strip 23, and a clamping strip 24 is provided on the surface of the pressure strip 23. The sides of the horizontal bar 101 and the vertical bar 102 are provided with a clamping groove 25. The clamping strip 24 can be clamped in the clamping groove 25. After the clamping strip 24 and the clamping groove 25 are clamped, the pressure strip 23 presses the glass 2. A notch is provided on the pressure strip 23, and the position of the notch corresponds to the limit block 3, thereby ensuring that the pressure strip 23 can cooperate well with the window frame 1.

[0035] When in use, it is only necessary to fix the horizontal rod 101 and the vertical rod 102 on the four sides of the window position of the building in sequence to fix the window frame 1, and then put the glass 2 into the window frame 1. At this time, the limit block 3 will automatically pop up to limit the glass 2, thereby preventing the glass 2 from tipping over. At this time, fix the pressure strip 23 to the window frame 1 to further fix the glass 2, and at the same time cover the limit block 3 to maintain the appearance, so as to complete all the installation steps. During the whole process, the limit block 3 will automatically slide out to limit the glass 2. There is no need to arrange workers to support the glass 2, and the original workers can take the pressure strip 23 by themselves to carry out the next step of installation.

[0036] The driving assembly includes a gear 4, a rack 5, a non-return assembly and a power assembly. The gear 4 is rotatably installed in the longitudinal rod 102, the rack 5 is slidably installed in the longitudinal rod 102, and the rack 5 is meshed with the gear 4. At the same time, the end of the rack 5 is fixedly connected to the limit block 3. The non-return assembly is installed in the longitudinal rod 102, and the rack 5 can only drive the limit block 3 to move toward the middle of the window frame 1 under the action of the non-return assembly. The power assembly is installed in the longitudinal rod 102, and the gear 4 is driven to rotate by the power assembly. In this way, the gear 4 can be driven to rotate by the power assembly to drive the rack 5 to slide, and then drive the limit block 3 to slide out automatically, and the non-return assembly can prevent the limit block 3 from retracting, thereby ensuring the reliability of limiting the glass 2.

[0037] The power assembly includes a reel 6, a pull wire 7 and a trigger assembly. The reel 6 is rotatably installed in the longitudinal rod 102, and the reel 6 is coaxially connected to the gear 4 and rotates synchronously. The end of the pull wire 7 is fixedly connected to the reel 6, and the pull wire 7 is wound on the surface of the reel 6. The trigger assembly is connected to the pull wire 7, and the reel 6 is driven to rotate by the trigger assembly. In this way, the reel 6 can be driven to rotate by simply triggering the pull wire 7 to move, and the reel 6 will drive the gear 4 to rotate.

[0038] The trigger assembly includes a trigger block 8, a slide plate 9, a first spring 10, a hook block 11 and a second spring 12. The trigger block 8 is slidably mounted on the side of the longitudinal rod 102 close to the middle of the window frame 1, and the glass 2 can push the trigger block 8 to slide. The slide plate 9 is slidably mounted in the longitudinal rod 102, and the end of the pull wire 7 away from the reel 6 is fixedly connected to the slide plate 9. The first spring 10 is mounted between the slide plate 9 and the longitudinal rod 102, and the slide plate 9 slides in a direction away from the reel 6 under the action of the first spring 10. The hook block 11 is rotatably mounted in the longitudinal rod 102, and the second spring 12 is mounted between the hook block 11 and the side wall of the longitudinal rod 102, and the hook block 11 hooks the slide plate 9 under the action of the second spring 12. The side of the trigger block 8 is tightly attached to the hook block 11, and the trigger block 8 can push the hook block 11 to rotate to separate from the slide plate 9.

[0039] In this way, after the glass 2 is placed in the middle of the window frame 1, the trigger block 8 will be synchronously pushed to retract into the longitudinal rod 102. In this way, the trigger block 8 will push the hook block 11 to rotate, thereby separating the hook block 11 from the slide plate 9 to release the limit on the slide plate 9. At this time, the slide plate 9 will slide upward under the action of the first spring 10, thereby pulling the pull wire 7 to drive the reel 6 to rotate.

[0040] The surface of the hook block 11 away from the part connected with the slide plate 9 is a wedge-shaped surface, and when the slide plate 9 moves toward the direction of the reel 6, the hook block 11 can be pushed away under the guidance of the wedge-shaped surface on the hook block 11. In this way, the reel 6 only needs to rotate the winding wire 7 to drive the slide plate 9 to move downward, and the slide plate 9 can automatically push the hook block 11 away and move to the bottom of the hook block 11. Then the hook block 11 can hook the slide plate 9 again under the action of the second spring 12, thereby providing conditions for the detachability of the entire fireproof window.

[0041] The non-return assembly includes a ratchet 13 and a pawl 14. The ratchet 13 is fixedly mounted on the rotating shaft of the gear 4. The pawl 14 is rotatably mounted in the longitudinal rod 102. The pawl 14 is equipped with a coil spring, and the pawl 14 is engaged with the ratchet 13 under the action of the coil spring. After the pawl 14 is engaged with the ratchet 13, the gear 4 can only drive the rack 5 to move toward the middle of the window frame 1. In this way, the limit block 3 can be limited in one direction to prevent it from retracting into the longitudinal rod 102 under pressure.

[0042] The driving assembly also includes a reset assembly, which includes a rotating rod 15 and a lever 16. A groove 17 is provided on the surface of the longitudinal rod 102, and a detachable cover plate 18 is covered at the opening of the groove 17. The rotating rod 15 is rotatably installed in the groove 17, and the rotating rod 15 is coaxially connected with the rotating shaft of the gear 4 and rotates synchronously. A slide groove is provided in the groove 17, and the lever 16 is slidably installed in the slide groove. The end of the lever 16 extends into the longitudinal rod 102 and is fixed to the surface of the pawl 14. When the lever 16 slides, it can drive the pawl 14 to rotate. The pawl 14 is separated from the ratchet 13. In this way, when disassembling the entire fireproof window, it is only necessary to pry open the cover plate 18 to slide the lever 16, and the lever 16 will drive the pawl 14 to separate from the ratchet 13. Then, the rotating rod 15 is rotated, and the rotating rod 15 will drive the gear 4 to rotate. The gear 4 will drive the rack 5 to slide, thereby driving the limit block 3 to retract into the longitudinal rod 102, thereby completely releasing the limit on the glass 2. At this time, the glass 2 is removed, and then the bolts fixing the cross bar 101 and the longitudinal bar 102 are removed to complete the disassembly.

[0043] The clamping assembly includes a clamping sleeve 19 and a clamping pin 20. The clamping sleeve 19 is fixedly installed in the cross bar 101, and the clamping pin 20 is fixedly installed on the slide 9. After the cross bar 101 is aligned with the longitudinal bar 102, the clamping pin 20 can be inserted into the clamping sleeve 19 under the action of the slide 9. In this way, all the longitudinal bars 102 and the cross bar 101 can be connected as a whole to ensure that the entire window frame 1 is more stable.

[0044] A through hole 21 is provided in the middle of the horizontal bar 101 and the vertical bar 102, and bolts can pass through the through hole 21 to facilitate installation. Baffles 22 are fixedly installed on the sides of the horizontal bar 101 and the vertical bar 102, and the edge of the baffle 22 extends to the middle of the window frame 1. At the same time, the distance between the baffle 22 and the limit block 3 is the same as the thickness of the glass 2. In this way, when installing, you only need to press the glass 2 against the baffle 22, and then when the limit block 3 slides out, the glass 2 can be fixed.

[0045] Therefore, the complete use process is to first install the window frame 1 on the window installation position, that is, to fix the window frame 1 to the wall by passing the bolts through the through holes 21. In this process, the horizontal bar 101 and the vertical bar 102 are installed in sequence, and the horizontal bar 101 and the vertical bar 102 need to be aligned;

[0046] After that, the glass 2 is placed in the middle of the window frame 1. During this process, the glass 2 will push the trigger block 8 to slide inside the longitudinal rod 102, and the trigger block 8 will push the hook block 11 to release the limit on the slide plate 9. At this time, the slide plate 9 will slide upward under the action of the first spring 10, thereby pulling the pull wire 7, the pull wire 7 will drive the reel 6 to rotate, the reel 6 will drive the gear 4 to rotate, the gear 4 will drive the rack 5 to slide, and then the limit block 3 will slide out from the side of the longitudinal rod 102 to support the glass 2, and then the card strip 24 on the pressure strip 23 is clamped with the card slot 25, so that the glass 2 and the window frame 1 can be fixed, and finally the structural glue is applied to the joint between the pressure strip 23 and the glass 2 to complete the installation;

[0047] When the slide plate 9 slides, it also drives the latch pin 20 to move synchronously, so that the latch pin 20 is inserted into the sleeve 19 . In this way, the cross bar 101 and the longitudinal bar 102 can be connected together, thereby further ensuring the stability of the glass 2 .

[0048] When dismantling is necessary, it is only necessary to cut off the structural glue, pry off the pressure strip 23, and then pry open the cover plate 18 to slide the lever 16, which will drive the pawl 14 to separate from the ratchet 13, and then rotate the rotating rod 15, which will drive the gear 4 to rotate, and the gear 4 will drive the rack 5 to slide, thereby driving the limit block 3 to retract into the longitudinal rod 102, thereby completely releasing the limit on the glass 2. At this time, remove the glass 2, and then remove the bolts fixing the cross bar 101 and the longitudinal rod 102 to complete the dismantling.

[0049] It should be noted that in the above steps, when the gear 4 rotates, the reel 6 will also be driven to rotate, and the reel 6 will reel the pull wire 7, thereby pulling the slide plate 9 downward to release the cooperation between the latch pin 20 and the sleeve 19. At the same time, during the downward movement of the slide plate 9, the hook block 11 will be pushed open. When the slide plate 9 is under the hook block 11, the hook block 11 will re-hook the slide plate 9 under the action of the second spring 12 to achieve reset;

[0050] At the same time, during the downward movement of the slide plate 9, it can move downward first under the action of the first spring 10. During this period of travel, the slide plate 9 will not contact the hook block 11, and during this period of travel, the limit block 3 will be completely retracted into the longitudinal rod 102, thereby avoiding the glass 2 pressing against the trigger block 8 and causing the trigger block 8 to be stuck and unable to slide.

[0051] In summary, during the entire use process, when installing the glass 2, the glass 2 can be limited by the limit block 3 that slides out automatically. In this way, there is no need to arrange workers to support the glass 2, which can greatly simplify the installation process, while reducing the number of workers and reducing installation costs.

[0052] At the same time, during use, the frame of the entire fireproof window is composed of a connecting component plus a horizontal rod 101 and a vertical rod 102. Under this structure, it can be disassembled during transportation, thereby greatly reducing the occupied space to facilitate transportation. After the glass 2 is installed, it can be automatically connected as a whole through the connecting component, which is also convenient to install.

[0053] It should also be noted that the trigger block 8 and the side of the limit block 3 close to the glass 2 are both wedge-shaped surfaces, so that the glass 2 can easily push the trigger block 8 to slide. At the same time, the wedge-shaped surface of the limit block 3 can also facilitate the gradual positioning of the glass 2 to avoid the end being blocked by the glass 2 and unable to be pushed to the middle of the glass 2;

[0054] Moreover, during the installation process, the trigger block 8 and the limit block 3 are staggered, that is, when the trigger block 8 is outside the longitudinal rod 102, the limit block 3 is inside the longitudinal rod 102. After the trigger block 8 is pushed into the longitudinal rod 102, the limit block 3 will be pushed out under the action of the driving component.

[0055] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
