The device for releasing the first locking member 50 and the second locking member 60 in linkage can adopt a commonly used linkage releasing device, which is described in detail here.
[0025] Please continue to refer to Figure 2The escape assembly 200 also includes two retractable guide rods 70 provided at the mounting end 131 of the frame 13. Both ends of the support member 35 are slidably connected to the guide rods 70. The escape device 100 is in a standby state, and the guide rods 70 are located in the storage space 11; the escape device 100 is in a working state, and the guide rods 70 extend out under the action of gravity. The guide rods 70 are utilized to facilitate the stable sliding of the support member 35, which is safe and reliable. When the bottom cover 15 is opened, the guide rods 70 can extend downward by gravity. Furthermore, both ends of the support member 35 are provided with C-shaped slide grooves 72 that cooperate with the guide rods 70. The purpose of setting the C-shaped slide grooves 72 is to facilitate the setting of a retractable protective cloth 90 on the periphery of the box body 10. Please refer to Figure 4 Specifically, the present application provides four fixed positions (not shown) on the frame 13 for installing the protective cloth 90. When the escape device 100 is in the extended state, the protective cloth 90, the telescopic ladder 20 and the guide rod 70 automatically extend downward to the next escape device 100, wherein the telescopic ladder 20 and the descender 30 are surrounded by the protective cloth 90, which is conducive to the escape of people who are afraid of heights. At the same time, in order to prevent someone from using the escape device 100 to reach the private floor, a zipper 91 is provided on the outer surface of the protective cloth 90, and the zipper 91 can only be opened from the outside of the protective cloth 90 to enter the escape device 100.
[0026] Please refer to Figure 2 A first connecting rod 71 is provided between the bottoms of the two guide rods 70, and a second connecting rod 73 is provided between the bottoms of the two guide rods 70 and the bottom of the telescopic ladder 20. The first connecting rod 71 and the second connecting rod 73 are used to connect the guide rods 70 and the guide rods 70 and the telescopic ladder 20, so as to improve the stability of the guide rods 70 and the telescopic ladder 20. Further, a plurality of escape devices 100 are arranged at intervals in the vertical direction, and the guide rod 70 of the escape device 100 located above the two adjacent escape devices 100 can abut against the box body 10 of the escape device 100 located below after being extended, and the connection is smooth. Specifically, the bottom of the guide rod 70 located above and the top of the guide rod 70 located below can be set to be convex and concave, but it is not limited to this. At the same time, the first connecting rod 71 of the escape device 100 located above abuts against the first locking member 50 of the escape device 100 located below, and can drive the first locking member 50 and the traction member 40 to release the lock. It is understandable that when the escape device 100 located at the top is in working state, the telescopic ladder 20 and the guide rod 70 extend under the action of gravity, thereby abutting against the escape device 100 located below, so that the escape devices 100 are connected to each other. Among them, the first connecting rod 71 abuts against the first locking member 50 of the escape device 100 located below and can be released, that is, the escape device 100 located below is released by the first connecting rod 71 to open the telescopic ladder 20 and the descender 30 in the escape device 100 located below.
[0027] Please refer to Figure 2The bearing member 35 includes a bearing plate 351, a slide plate 353, and an elastic member (not shown) disposed between the bearing plate 351 and the slide plate 353. The elastic member constantly folds the bearing plate 351 to the descending traction member 33. In other words, when the bearing plate 351 is not subjected to force, it is always folded to the descending traction member 33; when the user is riding, the bearing plate 351 is in an open position. In this embodiment, C-shaped slide grooves are disposed at both ends of the slide plate 353.
[0028] Combine the following Figure 1-Figure 4 The following describes the use and working principle of the escape assembly 200 of the present invention:
[0029] The escape assembly 200 is installed on the outer wall of the building floor. When not in use, the escape device 100 is in a standby state. At this time, the telescopic ladder 20, the descender 30, and the guide rod 70 are all retracted and stored in the storage space 11, the bottom cover 15 is engaged with the second locking member 60, the traction member 40 pulls the frame 13 in a retracted state, and the traction member 40 is engaged with the first locking member 50. The protective cloth 90 is retracted and tightly attached to the bottom of the frame 13, and the auxiliary fence 80 is retracted to the frame 13.
[0030] When the escape device 100 is needed, the user operates the traction member 40 and the first locking member 50 to release the lock, and the bottom cover 15 and the second locking member 60 are driven to release the lock. Under the action of the spring, the frame 13 moves from the mounting end 131 to the extension end 132 to be in the extended state. Since the bottom cover 15 and the second locking member 60 are released, the bottom cover 15 is opened, and the telescopic ladder 20 and the guide rod 70 extend downward under the action of gravity until they abut against the box 10 located below, and the first connecting rod 71 abuts against the first locking member 50 of the escape device 100 located below, that is, the escape device 100 located below is released by the first connecting rod 71, so as to open the telescopic ladder 20 and the descender 30 in the escape device 100 located below. At the same time, the user operates the auxiliary fence 80 to move upward, and under the action of the spring, when the engaging protrusion is engaged with the engaging hole, the auxiliary fence 80 is in a stable state. The user reaches a suitable position with the help of the auxiliary fence 80, and chooses the telescopic ladder 20 or the descender 30 to escape according to the situation, and reaches the escape device 100 located below, and also enters from the opening 138 to choose the telescopic ladder 20 or the descender 30 to escape, and so on, and can reach a safe area through the escape devices 100 on different floors.
[0031] Compared with the prior art, the escape assembly 200 of the present application includes several escape devices 100 installed on the outer wall of the building floor, and the personnel in the high-rise fire can escape from the fire scene to a safe place with the help of several escape devices 100. Among them, the escape device 100 includes a box 10 and a telescopic ladder 20 and / or a descender 30 connected to the box 10. When the escape device 100 is not needed, the escape device 100 is in a standby state, and the telescopic ladder 20 and the descender 30 are both retracted and located in the storage space 11 of the box 10 to avoid being fully exposed, which can extend their service life and avoid human damage. When encountering an emergency such as a fire, the escapee operates the bottom cover 15 to disengage from the frame 13, and the bottom cover 15 will automatically open under the action of gravity after disengaging. At the same time, under the action of gravity, the telescopic ladder 20 automatically extends downward until it abuts against the box 10 or the ground of the next escape device 100. In this process, the escapee can choose the descender 30 or the telescopic ladder 20 to escape according to the situation. In particular, people with limited mobility can choose the descender 30 and ride on the carrier 35 to escape safely and quickly. Therefore, the escape device 100 can meet the needs of various groups of people. In addition, the escape device 100 is arranged on the outer wall of the building floor to prevent the thick smoke from the fire on the floor from affecting the escaping personnel, and can ensure that the escaping personnel can escape from the fire scene quickly and safely to avoid accidents. At the same time, the escape device 100 has a simple structure, and when not in use, it is in a standby state, which is convenient for maintenance.
