Description
Technical field
The utility model relates to a kind of joint field, and more particularly, it relates to a kind of quick release coupling.
Background technique
It is extensive that quick release coupling uses very in hydraulic pipe line and pneumatic circuit and common pipeline, when usually needing to change different pipelines, open quick release coupling to change on different pipelines, although Placement facilitates many, but needing to close total valve before changing prevents the liquid in pipeline or gas from flowing out, and although some quick release coupling can seal some liquid or gas, but in hydraulic pipe line or pneumatic circuit, internal pipe pressure is larger, inner liquid or gas is caused to be subject to High Pressure and to flow out, thus quick release coupling sealing cannot satisfy the demands.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the quick release coupling providing a kind of good sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of quick release coupling, comprise adapter body, stationary body, described adapter body is fixedly connected with stationary body, described stationary body is arranged with stationary magazine creel, locking elastic part is provided with between described stationary magazine creel and adapter body, locking pellet is provided with between described stationary body and stationary magazine creel, spool is provided with in described stationary body, described valve core upper sleeve is provided with return springs, conflict in adapter body in described return springs one end, described spool comprises airtight head, vent rod, described vent rod one end is wholely set on airtight head, the described vent rod the other end is provided with sealing head, described sealing head excircle side is provided with the seal groove of annular, sealing rubber ring is provided with in described seal groove, described vent rod is provided with ventilation through hole near sealing head one end side, described adapter body is provided with the slip through hole coordinated with vent rod, described slip through hole is provided with the conical surface away from stationary body one end, described stationary body is provided with for airtight spacing limited step away from adapter body one end.
Preferably, described adapter body is provided with step near stationary body one end, and described step is provided with auxiliary rubber circle, and described auxiliary rubber circle is conflicted near stationary body one end packing ring, and described return springs is conflicted on packing ring.
Preferably, described airtight head inner circumference side is provided with fixed groove, is provided with fixing rubber ring in described fixed groove.
Preferably, described spool is made up of engineering plastics.
Compared with prior art, the beneficial effects of the utility model are: after the connecting head be connected with quick release coupling exits, spool loses the conflict power of connecting head, by the effect of return springs, spool is pushed to stationary body side, thus make sealing head enter in slip through hole, sealing head drives sealing rubber ring to slide axially, thus sealing rubber ring carries out compression along the conical surface enters in slip through hole, and when the larger sealing rubber ring of adapter body internal pressure more easily enters in slip through hole, sealing rubber ring is full of seal groove, thus sealing head and slip through hole are effectively sealed, and the pressure in adapter body all acts on spool, and the airtight head on spool is conflicted on limited step, thus spool cannot continue mobile, thus effectively avoid pressure excessive and produce leakage or gas leakage, and spool can effectively close automatically, without the need to closing total valve when making people use.

Embodiment
With reference to Fig. 1, the utility model quick release coupling embodiment is described further.
A kind of quick release coupling, comprise adapter body 1, stationary body 2, described adapter body 1 is fixedly connected with stationary body 2, described stationary body 2 is arranged with stationary magazine creel 3, locking elastic part 31 is provided with between described stationary magazine creel 3 and adapter body 1, be provided with between described stationary body 2 and stationary magazine creel 3 and lock pellet 32, spool 4 is provided with in described stationary body 2, described spool 4 is arranged with return springs 5, conflict in adapter body 1 in described return springs 5 one end, described spool 4 comprises airtight 41, vent rod 42, described vent rod 42 one end is wholely set on airtight 41, described vent rod 42 the other end is provided with sealing head 43, described sealing head 43 excircle side is provided with the seal groove 44 of annular, sealing rubber ring 45 is provided with in described seal groove 44, described vent rod 42 is provided with ventilation through hole 46 near sealing head 43 one end side, described adapter body 1 is provided with the slip through hole 11 coordinated with vent rod 42, described slip through hole 11 is provided with the conical surface 12 away from stationary body 2 one end, described stationary body 2 is provided with for airtight 41 spacing limited steps 33 away from adapter body 1 one end, after the connecting head be connected with quick release coupling exits, spool 4 loses the conflict power of connecting head, by the effect of return springs 5, spool 4 is pushed to stationary body 2 side, thus make sealing head 43 enter in slip through hole 11, sealing head 43 drives sealing rubber ring 45 to slide axially, thus sealing rubber ring 45 carries out compression along the conical surface 12 enters in slip through hole 11, and when the larger sealing rubber ring 45 of adapter body 1 internal pressure more easily enters in slip through hole 11, sealing rubber ring 45 is full of seal groove 44, thus sealing head 43 and slip through hole 11 are effectively sealed, and the pressure in adapter body 1 all acts on spool 4, and airtight 41 conflict on spool 4 is on limited step 33, thus spool 4 cannot continue mobile, thus effectively avoid pressure excessive and produce leakage or gas leakage, and spool 4 can effectively close automatically, without the need to closing total valve when making people use.
Described adapter body 1 is provided with step 13 near stationary body 2 one end, described step 13 is provided with auxiliary rubber circle 14, described auxiliary rubber circle 14 is conflicted near stationary body 2 one end packing ring 15, described return springs 5 is conflicted on packing ring 15, because return springs 5 is conflicted on packing ring 15, and packing ring 15 is conflicted on auxiliary rubber circle 14, thus the thrust that packing ring 15 is subject to return springs 5 makes auxiliary rubber circle 14 can effectively conflict in vent rod 42 excircle side, effectively raises sealing.
Described airtight 41 inner circumference sides are provided with fixed groove 47, are provided with fixing rubber ring 48 in described fixed groove 47, and when connecting head inserts block changing-over head, fixing rubber ring 48 is conflicted with connecting head, effectively raises airtight the sealing between 41 and connecting head.
Described spool 4 is made up of engineering plastics, engineering plastics have excellent combination property, and rigidity is large, and creep is little, mechanical strength is high, good heat resistance, can use for a long time, effectively raise working life in harsher physical environment, and avoid long-time use and produce wearing and tearing, and can form by integral molded plastic in the process manufactured, decrease the subsequent process steps of spool 4, greatly reduce difficulty of processing.
