[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-4 As shown, the present application provides a fireproof window, which mainly includes: a window body 1, including a window frame 11 and a window sash 12, the window sash 12 is installed with fireproof glass, and the window sash 12 is rotatably installed on the window frame 11 to be opened or closed; a driving rod 2, which includes a fixed cone 21 and a movable cone 22, the fixed cone 21 is arranged at the end of the driving rod 2, and the movable cone 22 is sleeved on the driving rod 2 and close to the fixed cone 21; a connecting part 4, one end of which is fixedly connected to the window frame 11, and a radially penetrating axial hole 41 is provided on the outside, the axial hole 41 is provided with at least two symmetrical positions, and a buckle 3 driven by elasticity is provided in the axial hole 41; the driving rod 2 forms a locking or unlocking with the connecting part 4 by maintaining pressure resistance with the buckle 3 through the fixed cone 21 or the movable cone 22, and when the driving rod 2 is locked with the connecting part 4, it is used to drive the window sash 12 to open or close.

[0023] Specifically, when the window sash 12 is in an open state, one end of the driving rod 2 forming the fixed cone 21 is inserted into the connecting portion 4. After insertion, the buckle 3 abuts against one end of the fixed cone 21, so that the driving rod 2 is locked in the connecting portion 4, and the window sash 12 can be pulled. When the window sash 12 is completely closed, it is inserted into the connecting portion 4 again, so that the movable cone 22 continues to slide in along the inclined surface of the locking block 31, the movable cone 22 fits with the fixed cone 21, and the driving rod 2 is unlocked from the connecting portion 4 and can be pulled out.

[0024] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0025] Reference Figure 3-4 As shown, the buckle 3 includes a locking block 31, a latch 32, and a spring 33. The spring 33 is sleeved on the latch 32. One end of the latch 32 is connected to the locking block 31, and the other end is formed with a convex portion abutting against the outside of the connecting portion 4. The spring 33 is used to apply a force to the buckle 3 always toward the inside of the connecting portion 4. The locking block 31 is designed at an angle. With this arrangement, the driving rod 2 can be quickly locked and unlocked inside the connecting portion 4.

[0026] Specifically, when the driving rod 2 is in a locked state, the locking block 31 is located between the movable cone 22 and the fixed cone 21. When the driving rod 2 is in an unlocked state, the locking block 31 is located at the end of the movable cone 22 away from the fixed cone 21. With this arrangement, unlocking and locking can be completed by just pressing, which greatly improves convenience.

[0027] Reference Figure 3 As shown, in order to allow the movable frustum 22 and the fixed frustum 21 to enter the interior of the connecting portion 4 at the same time and complete the unlocking function, the end of the movable frustum 22 with a larger outer diameter and the end of the fixed frustum 21 with a larger outer diameter are arranged opposite to each other, and the two ends of the fixed frustum 21 have the same outer diameter as the two ends of the movable frustum 22.

[0028] Specifically, in order to limit the distance of the active frustum 22 and prevent it from falling off, a limiting portion 23 is formed on the end of the driving rod 2 close to the active frustum 22 with a smaller outer diameter.

[0029] Reference Figure 2 As shown, the window sash 12 includes an upper frame, a lower frame and two side frames, and the connecting portion 4 is arranged in the middle of the lower frame.

[0030] Preferably, in order to facilitate the insertion of the driving rod 2 into the connecting portion 4, the extending axis of the connecting portion 4 has an inclined angle of 45-80° with the length direction of the lower frame, and specifically an angle of 60° is adopted in this embodiment.

[0031] Reference Figure 1 As shown, the window frame 11 is provided with a storage compartment 111 for accommodating the driving rod 2, and elastic components 112 for accommodating the driving rod 2 are provided at both ends of the storage compartment 111. This arrangement can effectively prevent the driving rod 2 from being lost or falling off, so that it can be taken out when needed.

[0032] Preferably, in consideration of emergency situations that may occur during a fire, a window-breaking cone head 24 is provided at one end of the driving rod 2 away from the fixed cone 21, which can quickly break the window glass and provide an escape route for personnel, greatly improving the survival rate in emergency situations.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
