Abstract
The utility model discloses a kind of pressure ventilation pipe of mine compressed air self-help apparatus, and there is the pressure ventilation pipe structure of certain sealing performance, comprise tee piece, connect pipe box, described connection pipe box two ends are respectively provided with a position limiting convex ring, connect between pipe box both ends of the surface to position limiting convex ring and be provided with internal thread, and screwing fixing with the external screw thread of tee piece end, the tee piece after screwing inserts between the end face of connection pipe box one end and position limiting convex ring and is provided with joint ring.The utility model structure is simple, has good sealing performance, conveniently carries out partial disassembly in later maintenance; The utility model has limit function when being threaded, and it is suitable for excessively screwing caused damage effectively to prevent from selecting.
Description
Technical field
The utility model relates to a kind of mine compressed air self-help apparatus, particularly relates to a kind of detachable pressure air pipe of mine compressed air self-help apparatus.
Background technology
The pressure air pipe of existing mine compressed air self-help apparatus is generally entirety, and this mode is unfavorable for maintenance, the replacing in later stage.Adopt segmentation structure in addition, be namely divided into a lot of section, adopt between every section and be threaded, this mode is very inconvenient when carrying out partial disassembly, even cannot carry out partial disassembly in the mounted state.And adopt and be threaded and sometimes do not reach good sealing performance, the breathing gas of rescue can be wasted during use.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide one and is applied on mine compressed air self-help apparatus easy to maintenance, and has the pressure ventilation pipe structure of certain sealing performance.
For achieving the above object, the utility model provides a kind of pressure ventilation pipe of mine compressed air self-help apparatus, comprise tee piece, connect pipe box, described connection pipe box two ends are respectively provided with a position limiting convex ring, connect between pipe box both ends of the surface to position limiting convex ring and be provided with internal thread, and screwing fixing with the external screw thread of tee piece end, the tee piece after screwing inserts between the end face of connection pipe box one end and position limiting convex ring and is provided with joint ring.
Further, described joint ring longitudinal thickness is not more than position limiting convex ring longitudinally height, and is provided with short slot with the end face cooperation place being connected pipe box one end.
Further, described sealing ring adopts elastomeric material to make, and tee piece, connection pipe box and position limiting convex ring all adopt stainless steel to make.
The beneficial effects of the utility model are: the utility model structure is simple, has good sealing performance, conveniently carries out partial disassembly in later maintenance; The utility model has limit function when being threaded, and it is suitable for excessively screwing caused damage effectively to prevent from selecting.

Fig. 1 is the structural representation of the pressure ventilation pipe detailed description of the invention of a kind of mine compressed air self-help apparatus of the utility model.
Fig. 2 is A place enlarged drawing in Fig. 1.
Fig. 3 is structural representation after the improvement of the pressure ventilation pipe detailed description of the invention of a kind of mine compressed air self-help apparatus of the utility model.
Fig. 4 is B place enlarged drawing in Fig. 3.
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 pressure ventilation pipe of mine compressed air self-help apparatus, comprise tee piece 1, connect pipe box 2, described connection pipe box 2 two ends are respectively provided with a position limiting convex ring 3, connect pipe box 2 both ends of the surface and be provided with internal thread between position limiting convex ring 3, and screw fixing with the external screw thread of tee piece 1 end, tee piece 1 after screwing inserts between the end face of connection pipe box 2 one end and position limiting convex ring 4 and is provided with joint ring 4, described joint ring 4 longitudinal thickness is not more than position limiting convex ring 3 longitudinally height, and is provided with short slot 5 with the end face cooperation place being connected pipe box 2 one end;
Described sealing ring 4 adopts elastomeric material to make, and tee piece 1, connection pipe box 2 and position limiting convex ring 3 all adopt stainless steel to make.
See Fig. 3 to Fig. 4, described tee piece be connected pipe box and tube connector can also be adopted to overlap insert the mode of tee piece link by threaded engagement, to be now arranged on tee piece link inner for position limiting convex ring 3, other assembling mode and the same in Fig. 1.
This structure is not only for convenience detach, but also there is good sealing function, can more save the air sent here outside in use, most importantly connect in pipe box 2 and be provided with position limiting convex ring 3, described position limiting convex ring 3 can avoid excessively being screwed in by the external screw thread of tee piece 1 end when assembling the connection instability, the even externally threaded situation in damage tee piece end that connect and cause in pipe box 2 effectively.
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 technician 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.
