Description

Technical Field

[0001] The invention relates to the technical field of escape devices, and in particular to a pop-up device for an escape bar on an escape window. Background Art

[0002] An escape window is a window installed inside a building, usually located on a burglar-proof window net, with a specific size and opening method to provide an escape route in an emergency.

[0003] For example, the Chinese patent: application number is 202310704057.9, and the patent name is a glass guardrail hidden escape device, "including a guardrail frame, and a glass block sealed on the guardrail frame, the guardrail frame is connected to at least one glass block by a locking structure, and the guardrail frame is connected to an escape bar through a wire release mechanism, and the escape bar includes a folding form and an unfolding form, the folding form is used for storage and hiding in the guardrail frame, and the unfolding form is used for escape." The existing escape bars are all stored in the storage cavity of the escape window, and in the event of a fire, the escaper needs to unlock the escape window and then manually push the escape bar out of the storage cavity, and the escape bar will be unfolded to allow the escaper to escape, but in the event of a fire, every minute is life time, and every minute faster the escape is, the safer the escaper is. The existing escape bar has too many operating steps, which greatly slows down the escape time of the escaper;

[0004] Existing escape windows all use a hinged swing rod as a support rod after the escape bar is unfolded, and this swing rod needs to bear the combined weight of the escapee and the escape bar. However, because the swing rod needs to be hinged to be stored in the escape window, when the escape bar is unfolded, the hinge point of the swing rod almost needs to bear the combined weight of the escapee and the escape bar. In this way, the hinge point of the swing rod is prone to breakage due to being unable to withstand such a heavy weight. Since the application scenario of the escape window is high in the air, when the hinge point of the swing rod breaks, the escapee will be in danger of falling from the building. Summary of the invention

[0005] The purpose of the invention is to provide a pop-up device for an escape bar on an escape window.

[0006] In order to achieve the above object, the present invention adopts the following scheme:

[0013] As a further solution of the present invention, a first inclined surface is provided at one end of the first buckle, and a second inclined surface is provided at one end of the second buckle. The buckling end of the second buckle extends upward, and the buckling end of the first buckle extends downward. The second buckle is made of elastic and restorative material, and through holes are symmetrically provided on both sides of the inner wall of the storage cavity.

[0014] As a further solution of the present invention, the fixing seat includes a fixing shaft symmetrically fixed on the top of the storage cavity, a limiting plate is fixed on the bottom of the fixing shaft, and a bearing is sleeved on the fixing shaft.

[0015] As a further solution of the present invention, the fixed shaft is designed to be inclined, and one end of the fixed shaft extends obliquely toward the inside of the storage cavity.

[0016] As a further solution of the present invention, the rotating rod includes a rotating sleeve arranged at the bottom of the fixed shaft and wrapping the limit plate and the bearing, and a load-bearing rod is fixed at the bottom of the rotating sleeve, and the load-bearing rod is L-shaped.

[0017] As a further solution of the present invention, the lifting rope group includes a fixing plate fixed in the storage cavity on one side of the fixing seat, the lifting rope is fixed on the fixing plate, and a rotating shaft is provided at the front end of the load-bearing rod for horizontal rotation. One end of the lifting rope passes through the fixing shaft and passes around the rotating shaft and then extends out of the load-bearing rod. One end of the lifting rope extending out of the load-bearing rod is connected to the escape fence, screw holes are provided on the fixing plate and the storage cavity, and the fixing plate is fixed to the storage cavity by screws.

[0018] As a further solution of the present invention, the lifting rope group includes a fixing plate fixed in the storage cavity on one side of the fixing seat, the lifting rope is fixed on the fixing plate, and a rotating shaft is provided at the front end of the load-bearing rod for horizontal rotation.

[0020] In summary, the invention has the following beneficial effects compared with the prior art: when a fire occurs, when the escapee opens the escape window, the escape bar automatically pops out from the storage cavity in the escape window under the action of the trigger mechanism, thereby omitting the operation steps of the escapee, greatly shortening the escape time of the escapee, allowing the escapee to escape from the fire faster, and improving the survival rate of the escapee;

[0021] In case of fire, after the escapee unfolds the escape bar, the reinforcement structure arranged between the inner wall of the storage cavity and the front end of the rotating rod will share part of the weight for the connection point between the fixed seat and the rotating rod on the swing rod, so that the total weight of the escapee and the escape bar will not be all applied to the connection between the fixed seat and the rotating rod, thereby increasing the upper limit of the maximum weight that the escape window can withstand and preventing the connection between the fixed seat and the rotating rod from breaking and causing the escapee to fall from the building. The fixed axis on the swing rod is arranged at an angle, so when the escape window is opened, due to the weight of the swing rod itself, the rotating rod will unfold automatically under the action of the weight, and after the rotating rod is unfolded, it will not close automatically without the action of external force, and will always remain in the unfolded state.

[0045] In use: when a fire occurs, the escapee unlocks the escape window to open it. In the initial state, the swing rod 3 is hung in the hanging plate 4 and stored in the storage cavity 2 of the window frame 1, and the first buckle 21 and the second buckle 22 are in a buckled state, the storage spring 6 is also in a compressed state, and one end of the pull rope 23 passes through the through hole 32 and is fixed on the expansion structure 200 of the escape window. When a fire occurs, the escapee unlocks the escape window to open it, and while the escape window is opened, the expansion structure 200 on the escape window is 00 will pull the pull rope 23. When the deployment structure 200 fully deploys the escape window, the deployment structure 200 will tighten the pull rope 23 and deform the second buckle 22. When the second buckle 22 is deformed, the first buckle 21 will separate from the second buckle 22, and the storage spring 6 will be released, thereby pushing the swing rod 3 to deploy under the action of the spring force of the storage spring 6, and at the same time driving the escape bar to pop out of the storage cavity of the escape window and deploy.

Figure 2 and Figure 5 As shown: It can be clearly seen from the figure that the fixed axis 111 is designed to be inclined, and one end of the fixed axis 111 extends obliquely toward the inside of the storage chamber 2. Therefore, when a fire occurs, after the escape window is unfolded, the rotating rod 120 will automatically unfold along the axis of the fixed axis 111 under the action of its own weight. Because after unfolding, the front end of the rotating rod 120 is inclined downward, so in the absence of external force, it will not close automatically and will always remain in the unfolded state. This can prevent the escapee from closing the rotating rod 120 due to misoperation when escaping. Because the fixed axis 111 is designed to be inclined, the rotating rod 120 will also unfold automatically, preventing the escape fence from having an accident when the escapee escapes because the rotating rod 120 is not fully unfolded. The reinforcement structure 140 can share part of the weight of the connection point between the fixed seat 110 and the rotating rod 120 after the escape fence is fully unfolded, so that the total weight of the escapee and the escape fence will not be all applied to the connection between the fixed seat 110 and the rotating rod 120.
