Description

Escape device Technical Field The invention relates to an escape device, in particular to an escape device combined with an iron window or a flower stand for use. Background In recent years, public safety incidents are frequently transmitted, people are extremely injured or even casualty is caused every time, particularly, once a fire accident happens, most people are choked by thick smoke and are faint and cannot escape under the condition that escape is not enough, however, a common iron window is provided with an escape opening so as to facilitate firefighters to connect and escape by using an aerial ladder, but the occurrence of the fire is usually suddenly insufficient, and after the occurrence, the firefighters usually have a plurality of mistakes in waiting processes until reaching the firefighters through notification and relief, so that the escape device can be combined with the iron window, and people can save oneself before the occurrence of the fire and waiting for the arrival of the firefighters, so that the best escape and prevention can be achieved. The existing safety escape structure is also combined with the iron window, but the existing escape iron window has the problems of complex structure and unfavorable emergency use, and is not suitable for common use of floors with multiple floors. Disclosure of Invention In order to solve at least part of the above problems, the escape device of the present invention is provided with a movable ladder on the periphery of a first and a second frame rails, so that the total length of the movable ladder is equal to the total length of the outer frames of the first and the second frame rails, and therefore, after the movable ladder is completely pulled down, the escape device can be used on the second to the fourth floors of the building to conform to the application of the common household floor. When an arch ladder is added to the bottoms of the first frame rail and the second frame rail, the total length of the movable ladder is lengthened again, so that the escape device is used for the fifth floor of the house floor. The escape device cuts off the first frame rail and the second frame rail to form four L-shaped rail structures so as to form a rectangular frame body, and the combined frame pieces are beneficial to carrying and assembling. Therefore, the escape device provided by the invention comprises a first frame rail and a second frame rail which are rectangular, are parallel and correspond to each other at intervals, and define an open track space, wherein the first frame rail and the second frame rail are respectively provided with an upper frame part, a lower frame part and two side frame parts. The frames are in an inverted U shape, each frame is bridged between one inner side face of the first frame rail and one inner side face of the second frame rail respectively, and the frames are provided with an open space communicated with the track space. And the fixed ladder is connected to the bottom of one side frame part of the first frame rail and the second frame rail. The pedal is erected on the lower frame parts of the first frame rail and the second frame rail and is at least erected on one of the frames of the lower frame parts of the first frame rail and the second frame rail.

According to the escape device of the invention, the height of the baffle plate is lower than the bottom of a top plate of the frame, so that the baffle plate can pass through the open space of the frame to move back and forth in the track space when moving along with the movable ladder. The escape device according to the invention further comprises a locking plate, wherein the locking plate is arranged at the lower frame parts of the first frame rail and the second frame rail and is adjacent to one side of the fixed ladder, the locking plate is provided with a locking hole, and the baffle is provided with an lug corresponding to the locking hole, so that the lug of the baffle can pass through the locking hole of the locking plate to be convenient for locking and positioning. The escape device according to the present invention further comprises a descent control device having a hanging portion for hanging on one of the frames. The escape device according to the present invention further comprises a plurality of triangular frames fixed at the bottoms of the lower frame portions of the first frame rail and the second frame rail, so as to be locked on a wall surface. The escape device according to the present invention further comprises an arch ladder and a hook chain connected to the end of the arch ladder, wherein the arch ladder has two arc rods and a plurality of step rods connected between the two arc rod
