Description
Technical Field
[0001] The utility model relates to the technical field of fire-resistant window equipment, in particular to a self-locking fire-resistant window. Background Art
[0002] Fire-resistant windows are generally set in openings or skylights on the exterior walls of buildings where the fire separation distance is insufficient, on fire walls or fire partitions inside buildings where observation is required, and in exterior wall openings where fire prevention and vertical spread of fire are required. A Chinese utility model patent, with the authorization announcement number "CN216894142U", discloses a self-locking fire-resistant window, comprising a window frame, and a fire-resistant window body installed inside the window frame, a handle is provided on the fire-resistant window body, a locking rod body movably connected to the handle is installed inside the fire-resistant window body, a lock body opened on the window frame is provided on one side of the fire-resistant window body, two limit rods movably connected by a spring are symmetrically arranged inside the lock body, a card slot matching the limit rod is symmetrically opened on the lock rod body, and a push rod is installed at one end of the limit rod.
[0003] The above technical solution is achieved by setting a limit rod, a spring, a slot and a push rod. When the locking rod body is inserted into the lock body, the two limit rods symmetrically set in the lock body will rely on the elasticity of the spring to engage in the slot provided on the locking rod body, thereby limiting the locking rod body, effectively preventing displacement, and improving the tightness of the closure, so that the fire-resistant window can be used normally. When there is no fire, when it is opened and closed normally, its self-locking fire-resistant window is not convenient for daily needs of ordinary windows due to its complicated self-locking device. Even if it is convenient to open and close, it is relatively troublesome to open and close. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solutions: a self-locking fire-resistant window, comprising a frame, a fire-resistant window body is rotatably connected to the surface of the frame, a handle shaft is rotatably connected to the surface of the fire-resistant window body, a handle is fixedly connected to the surface of the handle shaft, a second groove is provided on the surface of the fire-resistant window body, and mutually independent double limit devices are arranged inside the second groove;
[0006] The double limiting device comprises a cuboid, the surface of which is slidably connected to the inside of the second groove, and two second slots are provided on the surface of the cuboid;
[0007] Wherein, a third groove is provided on the surface of the fire-resistant window body, and a triangular piece is slidably connected inside the third groove;
[0008] Wherein, a first slot is provided on the surface of the frame, and the interior of the first slot contacts the surface of the triangle piece;

[0010] Preferably, a square hole is opened on the surface of the fire-resistant window body, a push button is slidably connected inside the square hole, and the surface of the push button is fixedly connected to the surface of the cuboid.
[0011] Preferably, a second spring is fixedly connected to the surface of the cuboid, and the other end of the second spring is fixedly connected to the inside of the second groove.
[0012] Preferably, a second rack is fixedly connected to the surface of the triangular piece, and the surface of the second rack is slidably connected to the inside of the third groove;
[0013] The inside of the third groove is rotatably connected with a second gear, the surface of the second gear is meshed with the surface of the second rack, and the surface of the second gear is fixedly connected with the surface;

[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] (1) When there is no fire, the self-locking fire-resistant window adopts a triangular piece in a double limit device. The handle is turned to drive the triangular piece inside the first slot to achieve the closing requirement. In daily use, only this method is used to close the fire-resistant window body. Compared with complex limit devices, although the closing performance is not strong, what is needed when there is no fire is convenience. However, the general self-locking fire-resistant window is not as convenient as the above method when there is no fire. When there is a fire, another independent limit device is used for double limiting, so that the closure is sufficient when a fire occurs and the opening and closing is convenient when there is no fire.
[0019] (2) There are two ways to rescue trapped people with the self-locking fire-resistant window. The first is to have firefighters enter the room to rescue. When the fire is too big to enter, the other is to enter the room from the outside through the window to rescue. The fire-resistant window needs to be closed while waiting, and when rescue is needed, the fire-resistant window needs to be opened quickly. By setting a second spring, the external force rotates the rotating button to drive the two clips out of the corresponding second slot, and the limiting device can be driven by the second spring to quickly escape from the first slot, saving the time required for pushing the button to drive the limiting device out of the first slot. Then, the handle is turned to drive the fire-resistant window body to open the window, thereby saving the window opening time and reducing the difficulty of rescue from the window.

[0047] When the fire-resistant window body 7 is locked in daily use, the handle 8 is driven to move by external force, the movement of the handle 8 drives the handle shaft 1 to move, the movement of the handle shaft 1 drives the fire-resistant window body 7 to rotate, the movement of the fire-resistant window body 7 drives the third groove 24 to move, the movement of the third groove 24 drives the triangular piece 18 to move until it coincides with the position of its first slot 9, the third spring 23 resets and drives the second rack 17 to move, the movement of the second rack 17 drives the triangular piece 18 to move to the inside of the first slot 9 to limit the positional relationship between the fire-resistant window body 7 and the frame 4.
[0048] When the fire-resistant window body 7 is opened in daily use, the handle 8 is rotated by external force to drive the handle shaft 1 to rotate, the rotation of the handle shaft 1 drives the second gear 16 to move, the movement of the second gear 16 drives the second rack 17 to move, the movement of the second rack 17 drives the third spring 23 to be compressed, the movement of the second rack 17 drives the triangle 18 to disengage from the inside of the first slot 9, and then the handle 8 is rotated to drive the fire-resistant window body 7 to rotate.

[0053] When there is no fire, a double limit device is provided in which a triangle piece 18 is driven by rotating the handle 8 to close the triangle piece 18 inside the first slot 9. In daily use, only this method is used to close the fire-resistant window body 7. Compared with a complex limit device, although the closing property is not strong, convenience is needed when there is no fire. General self-locking fire-resistant windows are not as convenient to close as the above method when there is no fire. When there is a fire, another independent limit device is used for double limiting, so that the closure is sufficient when a fire occurs and it is convenient to open and close when there is no fire.
[0054] There are two ways to rescue trapped people. The first is to have firefighters enter the room to rescue. When the fire is large and it is inconvenient to enter, the other is to enter the room from the outside through the window to rescue. The fire-resistant window needs to be closed while waiting, and when rescue is needed, the fire-resistant window needs to be opened quickly. By setting a second spring 21, the external force rotates the rotating button 3 to drive the two clips 14 out of the corresponding second slot 19, and the limiting device can be driven by the second spring 21 to quickly disengage from the first groove 15, saving the time required for the push button 6 to drive the limiting device to disengage from the first groove 15, and then the handle 8 is rotated to drive the fire-resistant window body 7 to open the window, thereby saving the window opening time and reducing the difficulty of rescue from the window.
