[0015] The following is combined with Figure 1-4 This application is described in further detail.

[0016] The present application embodiment discloses an escape device for an elevator car, referring to Figure 1 , Figure 2 and Figure 3 , including an installation frame 1, a baffle 2 and a movable part 64. The baffle 2 is movably hinged to the installation frame 1 through three hinges 3, so that the baffle 2 can be flipped on one side of the installation frame 1, thereby completely covering the interior of the installation frame 1. Six hexagon socket bolts 5 are threaded through the edge of one of the inner side walls of the installation frame 1. The six hexagon socket bolts 5 are rotated by an external hexagonal screwdriver so that the six hexagon socket bolts 5 are all threadedly connected to the inner wall of the elevator car, so that the installation frame 1 can be fixedly installed on the elevator car. A support part 61 is welded to the middle part of the inner side wall of the installation frame 1, and four first pedals 62 are welded to the inner side wall of one of the support parts 61. One end of the four first pedals 62 is welded to the other inner side wall of the support part 61, and the distances between the four first pedals 62 are the same. Slide grooves are provided on both sides of the support part 61, and L-shaped sliders 63 are slidably connected to the inside of the two slide grooves. The movable part 64 is located inside the installation frame 1, and the two One end of each L-shaped slider 63 is welded to the two sides of the movable part 64 respectively, and the two L-shaped sliders 63 cooperate to enable the movable part 64 to only be lifted and lowered vertically on one side of the support part 61. Four second pedals 65 are welded to the inner side wall of one of the movable parts 64, and one end of the four second pedals 65 are welded to the other inner side wall of the movable part 64. The spacing between the four second pedals 65 is the same. The bottom end of the movable part 64 is provided with a limiting component 7 for fixing the movable part 64 and the support part 61. After the limiting component 7 is pulled out to release the fixation between the movable part 64 and the support part 61, the movable part 64 will drive the four second pedals 65 to fall, and at the same time, the two L-shaped sliders 63 will slide to the inner bottom of the two slide grooves respectively. After that, the trapped personnel can climb the four second pedals 65 inside the movable part 64 and the four first pedals 62 inside the support part 61 to the escape hole at the top of the elevator car, and finally escape from the elevator car.

[0017] Reference Figure 1 and Figure 4 A first fixing block 41 is welded in the middle of the other side of the installation frame 1, and a second fixing block 42 is welded in the middle of the other side of the baffle 2. The second fixing block 42 is located at the bottom of the first fixing block 41. A plug 43 is movably penetrated in the middle of the top of the first fixing block 41, and the bottom end of the plug 43 is movably penetrated through the second fixing block 42. In this way, the baffle 2 and the installation frame 1 can be fixed after closing to prevent the baffle 2 from moving at will.

[0018] Reference Figure 2 and Figure 3The limiting assembly 7 is composed of an insert block 71 and a pull block 72. A clamping hole is provided at the bottom end of the movable portion 64 and the bottom end of the supporting portion 61. The two clamping holes correspond to each other. One end of the insert block 71 movably passes through the clamping hole provided at the bottom end of the movable portion 64 and is movably inserted into the inside of the clamping hole provided at the bottom end of the supporting portion 61. In this way, the movable portion 64 can be supported on one side of the supporting portion 61. The pull block 72 is welded to the other end of the insert block 71. The pull block 72 provided can facilitate pulling the insert block 71 out of the two clamping holes in turn, and then the support of the insert block 71 to the movable portion 64 can be released. At this time, the movable portion 64 can fall under the action of its own gravity.

[0019] Reference Figure 1 A first groove 81 is provided in the middle of the front side of the baffle 2, and a billboard can be pasted inside the first groove 81, which can serve as an advertisement. A second groove 82 is provided at the bottom end of the front side of the baffle 2, and a signboard with information on how to open the baffle 2, operate the movable part 64 to fall, and how to climb to escape can be pasted inside the second groove 82, so that trapped people can escape quickly after referring to this information.

[0020] The implementation principle of an escape device for an elevator car in an embodiment of the present application is as follows: when in use, refer to the information on the signboard pasted inside the second groove 82, operate the bolt 43 so that the bolt 43 is disengaged from the inside of the second fixing block 42 and the first fixing block 41, thereby opening the baffle 2, and then pull the plug block 71 out of the two card holes in turn through the pull block 72, and then the support of the plug block 71 on the movable part 64 can be released, and then the movable part 64 can fall under the action of its own gravity, and at this time the movable part 64 will drive the four second pedals 65 to fall, and at the same time make the two L-shaped sliders 63 slide to the inner bottom of the two slide grooves respectively, and then the trapped person can climb the four second pedals 65 inside the movable part 64 and the four first pedals 62 inside the support part 61 to the escape hole at the top of the elevator car, and finally escape from the elevator car.
