AI Technical Summary
Traditional fireproof windows are difficult to disassemble and assemble in emergency situations, requiring the unlocking of four fixing blocks one by one. This is cumbersome, and the fixing blocks at higher positions are difficult to access, increasing the difficulty and time required for the operation.
The limit block system, which uses a bidirectional threaded rod and a stepper motor to drive, enables the synchronous establishment or release of the four corner limits via a synchronous belt. Combined with magnetic positioning blocks and damping rotation blocks, it simplifies the disassembly process.
In an emergency, the four corner limit blocks retract simultaneously, allowing the mounting frame to quickly rotate to a vertical position, simplifying the disassembly process and enabling rapid and safe evacuation.

[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] Please see Figures 1 to 6 A fireproof window that is easy to disassemble includes a fixed frame 1 and an installation frame 4. Fireproof glass 5 is inlaid and installed on the installation frame 4. The fixed frame 1 needs to be stably fixed in the corresponding wall by means of expansion screws, etc. The installation frame 4 achieves stable installation of fireproof glass 5 by means of glass glue and pressure strips.
[0025] Two bidirectional threaded rods 9 are rotatably mounted inside the fixed frame 1. A synchronous belt 10 is provided between the two bidirectional threaded rods 9 via a pulley. Two nut pairs 11 are threadedly mounted on the bidirectional threaded rods 9. When one of the bidirectional threaded rods 9 is rotated manually or by a corresponding drive source, the presence of the synchronous belt 10 allows the two bidirectional threaded rods 9 to rotate synchronously.
[0026] Preferably, the synchronous belt 10 and the pulley can be connected by chain drive or gear drive to avoid slippage.
[0027] A movable plate 12 is fixedly installed between two nut pairs 11 on the same side. Two limiting blocks 2 are fixedly installed on the side of the two movable plates 12 facing the mounting frame 4. The mounting frame 4 has a limiting groove 6 that matches the limiting block 2 at the corresponding position.
[0028] The fixed frame 1 is equipped with a positioning component to facilitate positioning and installation activities.
[0029] A stepper motor 7 is mounted on the fixed frame 1, and the output end of the shaft of the stepper motor 7 is fixedly connected to one of the bidirectional threaded rods 9.
[0030] The two-way threaded rod 9 has threads in different directions on both sides. The two nut pairs 11 on the same two-way threaded rod 9 are located in different thread orientations. When the two-way threaded rod 9 rotates, the two nut pairs 11 can move closer to each other or further away from each other.
[0031] When the stepper motor 7 starts, the two bidirectional threaded rods 9 rotate synchronously through the action of the synchronous belt 10, and then the two nut pairs 11 on the same side drive the moving plate 12 to move synchronously, so the two moving plates 12 move closer or further away synchronously.
[0032] When the two movable plates 12 approach each other, the limiting block 2 will be inserted into the corresponding limiting groove 6, thereby realizing the fixed movement of the mounting frame 4, so that the mounting frame 4 is stably installed on the fixed frame 1 and will not move unexpectedly.
[0033] In case of an emergency, by moving the two movable plates 12 away from each other, the limiting block 2 can be moved out of the limiting groove 6, facilitating escape.
[0034] Rotating blocks 3 are fixedly installed at the top and bottom of one side of the mounting frame 4. The rotating blocks 3 are rotatably installed on the fixed frame 1. The mounting frame 4 can rotate so that during escape, the mounting frame 4 can be in a state perpendicular to the fixed frame 1, without the need for any destructive activities, and is convenient for continued use afterward.
[0035] Preferably, the rotation of the rotating block 3 should be damped so that the mounting frame 4 can be stably positioned at a fixed angle without swaying back and forth and without causing unnecessary impact on the escapees.
[0036] There are two positioning components, located on the top and bottom sides of the fixed frame 1, respectively.
[0037] The positioning assembly includes an operating lever 13, which is rotatably mounted on a fixed frame 1. A positioning block 14 is fixedly mounted on the operating lever 13. The positioning block 14 is n-shaped, and the fixed frame 1 has a receiving groove 8 at the corresponding position to accommodate the positioning block 14.
[0038] When the mounting frame 4 is rotated to the designated position (parallel to the fixed frame 1) by means of suction cups, the positioning block 14 can be rotated synchronously by manually rotating the operating lever 13. At this time, the mounting frame 4 is in the n-shaped space between the positioning blocks 14. The mounting frame 4 can limit the positioning blocks 14, which facilitates subsequent docking activities.
[0039] A magnetic block 15 is embedded on the side of the positioning block 14 facing the receiving groove 8. The magnetic block 15 can magnetically engage with the receiving groove 8. When not in use, the positioning block 14 cannot move due to the engagement between the magnetic block 15 and the receiving groove 8, thus not affecting the movement trajectory of the mounting frame 4.
[0040] It is worth noting that after installation, the positioning block 14 needs to be moved into the receiving groove 8 to ensure that the mounting frame 4 can rotate normally afterwards.
[0041] The working process of this utility model is as follows: First, the installation activity is carried out. The fixed frame 1 is fixed in the wall with expansion screws, etc. The fireproof glass 5 on the mounting frame 4 is firmly installed with glass glue and pressure strip. The mounting frame 4 is rotated to a position parallel to the fixed frame 1 using a suction cup or other tools. Then, the upper and lower operating rods 13 are manually rotated to make the mounting frame 4 enter the n-shaped space to limit the position of the mounting frame 4.
[0042] Then, the stepper motor 7 is started to drive the bidirectional threaded rod 9 to rotate. The synchronous belt 10 ensures that the two bidirectional threaded rods 9 rotate synchronously. Since the threads on both sides of the bidirectional threaded rod 9 are opposite, when they rotate, the two nut pairs 11 will move closer to each other. The moving plate 12 moves with the nut pairs 11, so that the limiting block 2 can be inserted into the limiting groove 6 on the mounting frame 4, thereby firmly fixing the mounting frame 4 to the fixed frame 1.
[0043] Then rotate the upper and lower operating levers 13 so that the positioning block 14 is in the receiving groove 8. The magnetic force between the magnetic block 15 and the receiving groove 8 ensures that the positioning block 14 will not affect the movement trajectory of the mounting frame 4 when it is not in use.
[0044] In an emergency, the stepper motor 7 reverses (which can be linked with the alarm), causing the two nut pairs 11 to move away from each other, thereby causing the limit block 2 to exit from the limit groove 6. Pushing the mounting frame 4 causes the rotating block 3 to rotate, thus making the mounting frame 4 perpendicular to the fixed frame 1, allowing for rapid escape without damaging the window.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
