AI Technical Summary
Due to the adhesion of foreign objects such as dust, the observation sheet of the self-rescue device in the mine is difficult for the staff to clearly observe the values on the pressure gauge.
A mining self-rescue device is designed, using a baffle and an observation port structure, and the observation port is opened by rotating the baffle, which facilitates staff to observe the pressure gauge. At the same time, the baffle can seal the observation port to prevent dust from entering.
It is achieved to prevent foreign objects such as dust from entering the self-rescue device without affecting the cleaning of the observation sheet, ensuring that the staff can clearly observe the values on the pressure gauge.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of emergency rescue equipment, and in particular to a mining self-rescuer. Background Art
[0002] The mine self-rescuer is an emergency escape device specially designed for underground coal mine accidents. It is used to protect the safety of miners in the event of harmful gas leakage or hypoxia.
[0003] A self-rescuer in the related art includes an upper shell and a lower shell. An oxygen tank is arranged in the lower shell. A pressure gauge is arranged on the end face of the oxygen tank facing the upper shell. An observation hole aligned with the pressure gauge is opened on the upper shell, and an observation piece is arranged in the observation hole.
[0004] There is a lot of dust in the environment under the mine, and the dust will adhere to the surface of the self-rescuer, that is, the surface of the observation piece. When the staff needs to check the pressure gauge, they usually clean the observation piece directly with their fingers. However, the above cleaning action will still leave dust, oil or fingerprints on the observation piece, making it difficult for the staff to clearly observe the value on the pressure gauge, so it needs to be improved.

The hinge 3 includes a connecting member 31 and a rotating shaft 32. The connecting member 31 is a sheet body, and the connecting member 31 is elastic. The connecting member 31 is provided with a first mounting hole on the end surface facing the cover body 2. The cover body 2 is provided with a second mounting hole, and the first mounting hole is aligned with the second mounting hole. The bolt 33 passes through the first mounting hole and is threadedly connected to the second mounting hole. The rotating shaft 32 is passed through the connecting member 31 and is rotatably connected to the shell 1.
[0043] Reference Figure 3 and Figure 4 , refer to Figure 4The end surface of the cover body 2 facing the connecting member 31 is fixedly connected to the limiting strip 4, and the limiting strip 4 includes two first limiting portions 41 and a second limiting portion 42. One first limiting portion 41 is located on one side of the horizontal connecting member 31, and the other first limiting portion 41 is located on the other side of the horizontal connecting member 31. The second limiting portion 42 is located on the side of the connecting member 31 away from the cover body 2, and is located between the two first limiting portions 41.
[0044] Reference Figure 5 and Figure 6 The locking structure 8 includes a locking tongue 81, a buckle 82, a hook 83 and a rotating rod 84. The rotating rod 84 is rotatably connected to the housing 1. The locking tongue 81 is sleeved outside the rotating rod 84. The buckle 82 is rotatably connected to the locking tongue 81.
[0045] Reference Figure 5 and Figure 6 The hook 83 is fixedly connected to the cover body 2. The buckle 82 can cooperate with the hook 83 to lock the cover body 2 and the housing 1.
[0046] Reference Figure 2 and Figure 3 An oxygen tank 5 is arranged in the receiving tank 11, and one end of the oxygen tank 5 is inserted into the storage tank 21. A pressure gauge 51 is arranged on the side of the oxygen tank 5 away from the bottom wall of the receiving tank 11, and the pressure gauge 51 is used to display the pressure in the oxygen cylinder so that the user can understand the remaining oxygen amount. A mouthpiece 52 is connected to the oxygen tank 5. The mouthpiece 52 is stored in the storage tank 21.
[0047] Reference Figure 3 and Figure 7 An observation port 23 is formed on the end surface of the cover body 2 away from the shell body 1 , and the observation port 23 is communicated with the storage slot 21 .
[0048] Reference Figure 2 and Figure 7 , the observation port 23 is aligned with the pressure gauge 51 on the oxygen tank 5. An observation sheet 24 is fixedly connected in the observation port 23, and the observation sheet 24 is transparent.
[0049] Reference Figure 7 The end face of the cover body 2 away from the cover body 2 is rotatably connected with a baffle 6, and the baffle 6 is transparent. The baffle 6 is used to block the observation port 23.
