[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 - Figure 3, an embodiment provided by the utility model: a liftable fireproof glass, including a load-bearing wall 1 for supporting the overall device. A fireproof layer is provided inside the load-bearing wall 1, which can block flames. A lifting component is provided inside the load-bearing wall 1, and the lifting component can lower the glass frame 31 and the fireproof glass 2, greatly exposing the window sill for people to pass through conveniently. A quick-release component is provided inside the load-bearing wall 1, and the quick-release component can quickly disassemble the glass frame 31 and the fireproof glass 2. The quick-release component includes the glass frame 31, and the inner wall of the top end of the glass frame 31 is fixedly connected with the fireproof glass 2. The fireproof glass 2 and the load-bearing wall 1 can relieve the spread of fire. The lifting component includes a gear two 43. The inner wall of the load-bearing wall 1 is elastically connected with a round block 46 through a limit spring 47. The limit spring 47 can limit the position of the gear two 43. The front surface of the gear two 43 is fixedly connected with a round rod 44. The front surface of the round rod 44 is fixedly connected with a turntable 45. The round rod 44 and the turntable 45 can rotate synchronously. The front surface of the turntable 45 is fixedly connected with a handle, and the handle is convenient to grip.
[0031] Refer to Figure 1 - Figure 3 , one end of the limit spring 47 is fixedly connected to the rear surface of the round block 46, and the other end of the limit spring 47 is fixedly connected to the inner wall at the rear side of the load-bearing wall 1. When the round block 46 moves forward, it will stretch the limit spring 47 to generate a reaction force. The front surface of the round block 46 is rotatably connected to the rear surface of the gear two 43, and when the gear two 43 rotates, it will not drive the round block 46 to rotate.
[0032] Refer to Figure 1 - Figure 3 , the round rod 44 penetrates through the front surface of the load-bearing wall 1, and the outer wall of the round rod 44 is in contact with the load-bearing wall 1. The load-bearing wall 1 can provide support for the round rod 44. The rear surface of the round rod 44 is fixedly connected to the center of the front surface of the gear two 43, and the front surface of the round rod 44 is fixedly connected to the center of the rear surface of the turntable 45. The centers of the round rod 44, the turntable 45, and the gear two 43 are on the same horizontal line. The rear surface of the handle is fixedly connected to a position on the front surface of the turntable 45 away from the center. Moving the handle can drive the turntable 45 to rotate.
[0033] Refer to Figure 1 - Figure 3 , the lifting component further includes a gear one 42. The gear one 42 is larger than the gear two 43. When the gear two 43 drives the gear one 42 to rotate, it is a labor-saving structure and is relatively easy to rotate. The inner wall of the load-bearing wall 1 is slidably connected with a rack 41, which slides up and down. A limit groove 401 is opened on the inner wall at the rear side of the load-bearing wall 1. The limit groove 401 is opened in a gear shape and has a size that fits the gear two 43.
[0034] Refer to Figure 1 - Figure 3, the rear surface of the first gear 42 is rotatably connected to the inner wall at the rear side of the load-bearing wall 1. The first gear 42 meshes with the second gear 43. When the second gear 43 rotates, it can drive the first gear 42 to rotate. The first gear 42 meshes with the rack 41. When the first gear 42 rotates, it can drive the rack 41 to move longitudinally. The second gear 43 is inserted into the inner wall of the limiting groove 401, and the second gear 43 will be limited and unable to rotate. When the second gear 43 is inserted into the limiting groove 401, the first gear 42 and the second gear 43 will be in a meshing state. When the second gear 43 is limited, the first gear 42 will also be limited.
[0035] Refer to Figure 1 , Figure 4 , the quick-release assembly further includes a connecting block 32. A wedge block 34 is elastically connected to the inner wall of the glass frame 31 through a compression spring 33. The compression spring 33 can limit the position of the wedge block 34. A clamping groove 301 is formed on the right surface of the rack 41.
[0036] Refer to Figure 1 , Figure 4 , the connecting block 32 penetrates and is slidably connected to the front surface of the glass frame 31 for easy movement. The wedge block 34 penetrates and is slidably connected to the left surface of the glass frame 31.
[0037] Refer to Figure 1 , Figure 4 , one end of the compression spring 33 is fixedly connected to the right surface of the wedge block 34, and the other end of the compression spring 33 is fixedly connected to the inner wall on the right side of the glass frame 31. When the wedge block 34 moves to the right, it will squeeze the compression spring 33 to generate a reaction force. The rear surface of the connecting block 32 is fixedly connected to the front surface of the wedge block 34, and the connecting block 32 and the wedge block 34 will move synchronously. When the wedge block 34 is inserted into the inner wall of the clamping groove 301, the glass frame 31 and the fireproof glass 2 can be fixed to the load-bearing wall 1.
[0038] Working principle: When a fire occurs, people need to escape through the emergency exit of the building. Windows provide people with an additional channel for emergency escape. When the fire approaches, the handle can be pulled forward to drive the turntable 45 to rotate. The handle moving forward will drive the turntable 45, the round rod 44, the second gear 43 and the round block 46 to move forward. The second gear 43 moving forward will disengage from the limit groove 401 to release the limit. The round block 46 moving forward will stretch the limit spring 47 to generate a reaction force. The rotating turntable 45 will drive the round rod 44 and the second gear 43 to rotate. The rotating gear 2 43 will drive the gear 1 42 to rotate in the opposite direction. The gear 1 42 rotating in the opposite direction will drive the rack 4 1. The glass frame 31 and the fireproof glass 2 are moved downward to the inside of the load-bearing wall 1, and then the gear 2 43 is released. The reaction force of the limit spring 47 will pull the round block 46 and the gear 2 43 to move backward. The gear 2 43 will be plugged into the limit groove 401 to ensure the stability of the device. At this time, the window sill will be in an open state, which is convenient for people to escape. In daily use, if ventilation is needed, the fireproof glass 2 can be lowered by rotating the turntable 45. When the fireproof glass 2 needs to be raised, just rotate the turntable 45 in the opposite direction. Compared with traditional glass windows, the present device can open the window sill to a large extent, which is convenient for people to pass through, and there will be no situation where the glass window sways and blocks people from passing.
[0039] When the fireproof glass 2 needs to be replaced, first move the connecting block 32 to the right to drive the wedge block 34 to move to the right to disengage from the slot 301 and release the limit, then remove the fireproof glass 2, and align the new fireproof glass 2 with the windowsill, then move the connecting block 32 to the right to drive the wedge block 34 to move to the right to release the obstruction, and the wedge block 34 moving to the right will squeeze the compression spring 33 to generate a reaction force, then install the fireproof glass 2 into the load-bearing wall 1, and release the connecting block 32, the reaction force of the compression spring 33 will push the wedge block 34 to move to the left and plug into the slot 301 to complete the installation of the fireproof glass 2.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
