[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0032] Reference Figures 1 to 10 A hidden escape window includes an escape basket 1, a receiving cavity 2 disposed on a wall and capable of receiving the escape basket 1, and a window 3 disposed on the wall and capable of covering the receiving cavity 2. The escape basket 1 includes a folded form for receiving the escape basket in the receiving cavity 2 and an unfolded form for escaping. The escape basket 1 includes a first frame 11 disposed on the front side, a second frame 12 disposed on the rear side, and also includes:

[0033] Suspension wire 4: arranged in the receiving chamber 2 and used for suspending the escape basket 1;

[0034] Swing arm mechanism 5: rotatably disposed at the upper end of the receiving chamber 2 and used to provide auxiliary support for the suspension wire 4;

[0035] The storage mechanism 6 is disposed in the first frame 11 and is used to store the suspension wire 4;

[0036] A wire-releasing mechanism 7 is provided on the first frame 11 and can release the hanging wire 4 to make the escape basket 1 descend;

[0037] The balance support mechanism 8 is arranged on the suspension wire 4 and can make the escape basket 1 descend smoothly.

[0038] In this way, the suspension line 4 of the escape basket 1 is supported by the swing arm mechanism 5 when the escape basket 1 is in the unfolded state, ensuring that the escape basket 1 can be released and lowered, and the swing arm mechanism 5 can also drive the escape basket 1 to separate from the receiving chamber 2 during the swinging process, which is conducive to pushing the escape basket 1 out of the receiving chamber 2. The escape basket 1 is stored in the receiving chamber 2, making the window 3 look more simple and beautiful as a whole, and does not affect the appearance of the building. In addition, the suspension line 4 is only set on one side of the first frame 11, and the structure is simpler. In addition, through the provided balance support component, the escape basket 1 will not be overturned due to the force concentrated on only one side of the first frame 11 during the descent process, thereby ensuring the safety performance of the escape basket 1 during the descent process, so that it can be smoothly descended.

[0039] In this solution, the swing arm mechanism 5 includes a fixed shaft 51 obliquely arranged in the receiving chamber 2, and a swing rod 52 rotatably arranged in the fixed shaft 51. When the escape basket 1 is in a folded state, the swing rod 52 is stored in the receiving chamber 2 and is in a horizontal state. When the escape basket 1 is in an unfolded state, the swing rod 52 extends out of the receiving chamber 2 and tilts downward. The swing rod 52 is hollow, and the suspension line 4 passes through the entire swing rod 52 and is fixed in the receiving chamber 2. A support shaft 53 that can support the suspension line 4 is provided inside the swing rod 52 and at the extended end. Furthermore, a first ring is provided outside the swing rod 52 and at the extended end, a second ring is provided inside the receiving chamber 2 and at the front side of the fixed shaft 51, and a support line that can connect the first ring and the second ring is provided between the first ring and the second ring, and the swing rod 52 is supported by the support line to prevent it from being bent. In this way, after the window 3 is opened, the swing rod 52 will rotate and unfold automatically due to its own weight, and after unfolding, the swing rod 52 will not swing due to the effect of weight, thereby ensuring the stability of the escape basket 1 during the descent process.

[0040] In the present embodiment, a pop-up mechanism is provided in the receiving chamber 2, which can push the rocker arm 52 out of the receiving chamber 2. The pop-up mechanism includes a push plate 91 which is arranged in the receiving chamber 2 and can move forward and backward to push the rocker arm 52 out of the receiving chamber 2, a spring 92 which is arranged on the rear side of the push plate 91 and drives the push plate 91 to move, a fixing seat 93 which is arranged on the inner wall of the receiving chamber 2 and is used to assemble the spring 92, and a trigger structure 94 which is arranged in the spring 92 and can keep the spring 92 in a compressed state. The push plate 91 has a C-shaped groove on one side which cooperates with the rocker arm 52. Specifically, the trigger structure 94 includes a first buckle 941 arranged on the fixed seat 93, a second buckle 942 arranged on the push plate 91 and engageable with the first buckle 941, and a pull rope 943 arranged at the bottom of the second buckle 942, one end of the first buckle 941 is provided with a first inclined surface, and one end of the second buckle 942 is provided with a second inclined surface, the engaging end of the second buckle 942 extends upward, and the engaging end of the first buckle 941 extends downward, and the second buckle 942 is made of a material with elasticity and restorability, the window 3 includes a telescopic frame 31 arranged on the wall, and a glass plate 32 arranged on the telescopic frame 31, a through hole (not shown in the figure) for the pull rope 943 to pass through is provided in the accommodating cavity 2, and the protruding end of the pull rope 943 passes through the through hole and is connected to the telescopic frame 31. In this way, after the window 3 is opened, the pull rope 943 will be pulled to unlock the trigger structure 94, and then the push plate 91 will push the swing rod 52 out of the receiving chamber 2, thereby accelerating the speed at which the swing rod 52 swings out, ensuring enough time for escape.
