[0007] A sealing gasket is provided between the escape capsule bodies and is connected by a plurality of fixing screws; a sealing gasket is provided between the connecting door and the escape sealed capsule body and is connected by a plurality of fixing screws.

[0008] Both sides of the escape sealed cabin are provided with tempered glass, and the connection between the multiple escape cabins is provided with tempered glass.

[0009] The filtering device includes a connecting shell, a first filter screen and a second filter screen. The connecting shell is fixed on the top of the escape capsule body. The first filter screen is provided on both side walls of the connecting shell. The second filter screen is provided on the bottom of the connecting shell. A fan is provided under the second filter screen.

[0010] A motor is provided on the inner side of the bottom of the escape capsule, and wheels are rotatably connected to the outer side of the bottom of the escape capsule. The motor output shaft passes through the escape capsule and the wheels to connect to a bevel gear set, and the motor drives the bevel gear set to rotate the wheels.

[0011] The connecting doors are all provided with handles.

[0012] The beneficial effects of the utility model are as follows: the utility model seals and splices a plurality of escape capsules together to form an escape sealed capsule through fixing screws, and connects the connecting doors to both sides of the escape sealed capsule through fixing screws, thereby achieving the effect of being able to splice and adjust according to the conditions of the coal mine tunnel and the number of workers in the coal mine, so as to adapt to the use needs of different coal mines.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] An improved coal mine safety emergency escape closed cabin, such as Figure 1-Figure 3 As shown, it includes an escape capsule 1, tempered glass 2, a connecting shell 3, a first filter 4, a second filter 5, a fan 6, a motor 7, a bevel gear set 8, a wheel 9, a sealing gasket 10, a fixing screw 11, and a connecting door 12. Multiple escape capsules 1 are sealed and connected to form an escape sealed capsule 13. Both sides of the escape sealed capsule 13 are sealed and connected to the connecting door 12. A sealing gasket 10 is provided between the escape capsules 1 and connected by multiple fixing screws 11; a sealing gasket 10 is provided between the connecting door 12 and the escape sealed capsule 13 and connected by multiple fixing screws 11; tempered glass is provided on both sides of the escape sealed capsule 13, and tempered glass is provided at the connection between multiple escape capsules 1.

[0019] A filtering device is provided at the top of the escape capsule body 1, and a fan 6 fixed to the inner side of the top of the escape capsule body 1 is provided below the filtering device; the filtering device includes a connecting shell 3, a first filter screen 4, and a second filter screen 5. The connecting shell 3 is fixed to the top of the escape capsule body 1, and the two side walls of the connecting shell 3 are provided with a first filter screen 4, the bottom of the connecting shell 3 is provided with a second filter screen 5, and a fan 6 is provided below the second filter screen 5.
