Description
Technical field
The utility model relates to a kind of mining rescue equipment, particularly relates to a kind of compressed oxygen self-lifesaving device.
Background technology
Mostly be provided with filter tracheae in the peace and quiet tank of existing compressed oxygen self-rescuer for mineral, but toward in peace and quiet tank during powder charge, due to filter tracheae from peace and quiet tank mouth close to and filter tracheae and sidewall comparatively closely, this can cause powder charge and get it filled very not easily.Have because filled medicine is generally calcium hydroxide again, its water imbibition is very strong, if the improper meeting of peace and quiet Jar opening sealer causes calcium hydroxide to absorb water, accelerates the inefficacy of medicine.Mostly adopting the peace and quiet tank mouth of sealing-plug jam-pack in prior art, or directly adopt seal with screwed joint, there is following defect in these two kinds of modes: 1, the words of employing sealing-plug can be very difficult when extracting; 2, adopt its sealing effectiveness of words of screw thread to be nothing like sealing-plug, sealing effectiveness is undesirable, and seal cover dismounting difficulty, lacks special detaching structure and extracting tool.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model be to provide a kind of peace and quiet tank mouth adopt seal cover by thread seal, good airproof performance, be easy to dismounting and powder charge, compressed oxygen self-lifesaving device easily of getting it filled.
Another object of the present utility model is the instrument of the seal cover provided in a kind of above-mentioned purpose for convenience detach.
For achieving the above object, the utility model provides a kind of compressed oxygen self-lifesaving device, comprise in peace and quiet tank, described peace and quiet tank and be provided with filter tracheae, described peace and quiet pot bottom is provided with peace and quiet tank mouth, screwed by screw thread and seal cover outside described peace and quiet tank mouth, described seal cover is also provided with a sealing-plug; Described filter tracheae is Rotary-table structure, its diameter compared with small end near peace and quiet tank mouth; Described seal cover outside in petal, and be at least provided with 8 circular arc evaginations and connect the circular arc indent of circular arc evagination.
Further, described sealing-plug adopts gluing mode to be fixed on seal cover and adopts elastomeric material to make.
Further, described sealing-plug and seal cover link seal cover completely with peace and quiet tank mouth outside screw time, sealing-plug has at least three millimeters stretch out peace and quiet tank mouth and form gap with seal cover.
Further, described circular arc evagination is identical with circular arc indent radian and arc length.
For an opener for opening encapsulation lid, comprise handle and engaging head, described engaging head is provided with the arc concave shape coordinated with circular arc evagination on seal cover, and described arc concave shape connects into a circle by arc evagination.
The beneficial effects of the utility model are: the utility model structure is simple, good airproof performance, seal cover are easily dismantled, powder charge, convenience of getting it filled, and have special opener, can improve maintenance efficiency widely.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 2, a kind of compressed oxygen self-lifesaving device, comprise peace and quiet tank 1, peace and quiet tank mouth 11 is provided with bottom described peace and quiet tank 1, screwed by screw thread and seal cover 5 outside described peace and quiet tank mouth 11, described seal cover 5 is also provided with a sealing-plug 4, described sealing-plug 3 can adopt gluing mode to be fixed on seal cover 5 and adopt elastomeric material to make;
Be provided with in described peace and quiet tank 1 filter tracheae 2, described filter tracheae 2 is Rotary-table structure, its diameter compared with small end near peace and quiet tank mouth 11;
Described sealing-plug 3 and seal cover 5 link seal cover 5 completely with peace and quiet tank mouth 11 outside screw time, sealing-plug 3 has at least three millimeters stretch out peace and quiet tank mouth 11 and form gap 4 with seal cover; Even if when taking out seal cover 5, sealing-plug 3 comes off like this, also can be easy to be taken out by its extension;
Described seal cover outside in petal, and be at least provided with 8 circular arc evaginations 51 and connect the circular arc indent 52 of circular arc evagination 51, described circular arc evagination 51 and circular arc indent 52 preferably structure identical (radian is identical with arc length).
For an opener for opening encapsulation lid 5, comprise handle 6 and engaging 7, described engaging 7 is provided with the arc concave shape 71 coordinated with circular arc evagination 51 on seal cover 5, and described arc concave shape 71 connects into a circle by arc evagination 72.
When needing powder charge or get it filled, first use opener opening encapsulation lid 5, then directly carry out powder charge or get it filled, now, owing to filtering tracheae 2 diameter compared with small end towards peace and quiet tank mouth 11, this section and peace and quiet tank skin have larger distance, understand easily in powder charge or when getting it filled.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
