Description
Technical field
This utility model belongs to medical apparatus and instruments auxiliary equipment field, is specifically related to a kind of blast connection for inflated type heat-insulation system。
Background technology
Inflated type heat-insulation system is often used during hospital surgical, and it can provide heat to hypothermic patient during operation, reduces operation risk.Existing inflated type heat-insulation system uses frequency the highest be exactly inflatable thermal insulation blanket, the structure such as including air supply system, insulating gasbag and the gas transmission corrugated conduit that is connected with air supply system and insulating gasbag.In actual use, inflated type heat-insulation system also relates to important connection member, i.e. a blast connection.By blast connection, air supply system is attached with gas transmission corrugated conduit so that it is insulating gasbag can be inflated.
But traditional inflated type heat-insulation system blast connection uses overlong time to there will be poorly sealed, easily the phenomenon of gas leakage.And assembly manipulation is loaded down with trivial details, efficiency of assembling is relatively low, disassembles the most cumbersome.
Summary of the invention
The inflated type heat-insulation system blast connection that this utility model mainly solves existing for prior art is poorly sealed, easily leaks gas, assembles, dismantles troublesome technical problem, it is provided that a kind of simple in construction, it is possible to the self-locking blast connection of rapid-assembling/disassembling.
What this utility model was above-mentioned technical problem is that is solved by following technical proposals: described self-locking blast connection includes nut, fittings body and sealing ring；Wherein, described nut includes the gas input being connected with air supply system and the locking-up end being connected with fittings body；Described locking-up end and gas input are cirque structure, and locking-up end inwall is provided with three equally distributed grooves along inwall circumferencial direction, is provided with the inner slide of connection between two adjacent grooves；Described inner slide sidewall is along the direction progressive additive that turns clockwise；Being provided with annular groove bottom described locking-up end, described sealing ring is arranged in annular groove；Described fittings body includes the gas output end being connected with gas transmission corrugated conduit and the locking end being connected with nut；Described locking end and gas output end are cirque structure, and locking end race diameter is identical with gas output end inner ring diameter；Described gas output end is provided with female thread；It is provided with annular boss outside described locking end top, makes to be formed between gas output end and annular boss an annular groove；Described annular boss outer surface is circumferentially with three equally distributed projections, and described projection becomes α angle with boss base；The groove projected through on nut on described fittings body inserts in inner slide, turns clockwise along inner slide and locks.
Preferred as the present invention, the female thread of described fittings body gas output end is M72 levogyrate inner thread, and described nut gas input is the chassis interface of Φ 70.
For prevent from turning clockwise fittings body or nut time hands perspire, skid, the locking-up end outer periphery of the gas output end of described fittings body and nut is provided with fin.
Advantage of the present invention and beneficial effect:
(1) self-locking blast connection simple in construction described in the utility model, easily manufactures, good sealing effect, assembling, convenient disassembly, it is possible to increase the work efficiency of medical and nursing work personnel.
(2) self-locking blast connection installation pipeline described in the utility model is not required to instrument and is inserted directly in pipe joint, fittings body and nut can auto lock pipe fitting, good sealing effect, even if long-time use does not haves the phenomenon of gas leakage yet.

Detailed description of the invention
Refering to Fig. 1, self-locking blast connection described in the utility model includes nut 1, fittings body 2 and sealing ring 3；Wherein, described nut 1 includes the gas input 11 being connected with air supply system and the locking-up end 12 being connected with fittings body 2；Described fittings body 2 includes the gas output end 21 being connected with gas transmission corrugated conduit and the locking end 22 being connected with nut；Described sealing ring 3 uses elastomeric material to make, and it is internal to be arranged on nut 1 locking-up end 12；The gas output end 21 of described fittings body 2 is cirque structure with the locking-up end 12 of nut 1, and outer periphery is provided with fin 211, and 124, the locking-up end 12 on nut 1 is connected with the locking end 22 on fittings body 2 and locks.
Refering to Fig. 1, Fig. 3, described gas input 11 is the chassis interface of Φ 70；Described locking-up end 12 inwall is provided with three equally distributed grooves 121 along inwall circumferencial direction, is provided with the inner slide 122 of connection between two adjacent grooves 121, and described inner slide 122 sidewall is along the direction progressive additive that turns clockwise；Being provided with annular groove (unmarked) bottom described locking-up end 12, described sealing ring 3 is arranged in annular groove.
Refering to Fig. 1, Fig. 2, Fig. 3, described locking end 22 is cirque structure with gas output end 21, and locking end 22 race diameter is identical with gas output end 21 inner ring diameter；Described gas output end 21 is provided with M72 levogyrate inner thread (unmarked)；It is provided with annular boss 221 outside described locking end 22 top, makes to be formed between gas output end 21 and annular boss 221 annular groove 222；Described annular boss 221 outer surface is circumferentially with three equally distributed protruding 223, described protruding 223 and becomes α angle with boss 221 base.
In practical work process, gas transmission corrugated conduit is connected on the gas output end 21 of fittings body 2, the gas input 11 of nut 1 is fixed on air supply system.Then, inserting in inner slide 122 by the projection 223 on fittings body 2 by the groove 123 on nut 1, turning clockwise along inner slide 122 carries out locking.
