Description
Technical field
The utility model relates to a kind of LP gas cylinder connector.
Background technique
The LP gas cylinder of using is connected with the liquefied petroleum gas (LPG) utensil by behind the reduction valve now, after liquid gas uses up, when needing to change LP gas cylinder, after needing to screw out reduction valve, again reduction valve is screwed in new LP gas cylinder, whole replacing process is loaded down with trivial details, and the bad gas leak that easily causes is installed.Therefore, a kind of LP gas cylinder connector has appearred.This kind connector is made up of joint and connecting sleeve.One end of joint screws in LP gas cylinder, and an other end can insert connecting sleeve, and an other end of connecting sleeve then connects reduction valve.Joint inside by a copper ball that is pressed with spring realize its air vent open with or the sealing.When joint separated with connecting sleeve, copper ball was subjected to the spring compressing and blocks air vent, and after joint inserted connecting sleeve, joint and connecting sleeve were locked mutually, and copper ball is compressed by external force simultaneously, and pressure spring is opened air vent.But when the airflow passes copper ball, copper ball can ceaselessly vibrate with air-flow owing to be not subjected to the contact location of inner nosepiece wall, makes Throughput inhomogeneous, and copper ball and spring are come off, and makes copper ball lose forcing down of spring.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to use, even, durable LP gas cylinder connector of ventilating.
In order to achieve the above object, the utility model is by the following technical solutions: described LP gas cylinder connector is made up of joint and connecting sleeve, all there is a cavity joint and connecting sleeve inside, one end of joint is the connecting end that can be connected with LP gas cylinder, one end of connecting sleeve is the connecting end that can be connected with reduction valve, joint and connecting sleeve interconnect and are automatically locked between the end and trip gear, there is a top that is pressed with the air intake of spring and sealed adapter sleeve cavity to fill in the connecting sleeve cavity, in the plug of top an air vent is arranged, side, air vent two ends has through hole, in the internal cavities of joint, have one with cavity vent plug movingly, have vent on the vent plug, vent plug one end is pressed with spring, and an other end and the joint cavity air outlet of vent plug are sealed and matched.
Adopt LP gas cylinder connector described in the utility model, one end and the gas cylinder of joint are connected and fixed, one end and the reduction valve of connecting sleeve are fixed, connecting sleeve is inserted in joint, between them be automatically locked and trip gear is automatically locked, joint and connecting sleeve are connected together, the front end of the top of connecting sleeve inside plug stretches in the joint cavity simultaneously, the top plug all suffers oppression with vent plug and moves backward, removed the sealing between the air intake of sealing between vent plug and the joint cavity air outlet and top plug and connecting sleeve cavity, joint is communicated with the cavity of connecting sleeve; Be automatically locked and trip gear when stirring, joint and connecting sleeve are thrown off automatically, top plug, vent plug decompression power, under the effect of spring, rebound, the air intake of the air outlet of vent plug and joint and top plug and connecting sleeve all forms again and is sealed and matched, and can prevent that liquid gas residual in the connecting tube between liquid gas apparatus and the connecting sleeve from overflowing.LP gas cylinder connector described in the utility model is simple to operate, safety, simultaneously since vent plug and joint cavity for movingly, vent plug can not be subjected to the impact of air-flow and produce vibration, minimizing has improved the working life of connector because of the damage that vibration causes, and gives vent to anger evenly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.

Embodiment
Embodiment:
As shown in Figure 1, joint a comprises steel cylinder top plug 1, spring top cover 2, spring 3, adapter sleeve 4, vent plug 5, seal ring 6 and seal ring 15; Connecting sleeve comprises thrust spring 7, ball 8, fittings body 9, interior sleeve spring 10, connects block set 11, outer casing spring 12, connects overcoat 13, thrust slide block 14, top plug 20.
The spring that steel cylinder top plug 1 is fixed in the front end of adapter sleeve 4 pushes up on the cover 2, being used for forming hermetic seal with steel cylinder is connected, vent plug 5 is positioned at the cavity of adapter sleeve 4, between itself and adapter sleeve 4 inwalls for movingly, be pressed with spring 3 between vent plug 5 and the spring top cover 2, have vent 16 on it, between vent plug and adapter sleeve 4 right output port seal ring 6 is arranged, make vent plug and adapter sleeve right-hand member form tightness and be connected.Inboard right output port at adapter sleeve 4 is furnished with three seal rings 15.
Connection block set 11 inside of connecting sleeve b have the gas ventilation road, its right-hand member can be connected with reduction valve, have a top that is pressed with the air intake of spring 21 and sealed adapter sleeve cavity to fill in 20 in the connecting sleeve internal cavities, in the top plug 20 air vent 22 is arranged, air vent two ends sidewall has through hole 23.Top plug convex portion 18 is slidingly matched for 19 one-tenth with the top plug sliding sleeve of connecting sleeve internal projection, and the outside of top plug sliding sleeve 19 can form hermetic seal with the seal ring 16 of adapter sleeve 4 and cooperate.Fittings body 9 is placed in and connects on the block set 11, installs on it to be automatically locked and trip gear.
Between joint a and the connecting sleeve b be automatically locked and trip gear is a prior art, as long as it can be realized being automatically locked mutually of joint a and joint b and throw off, being automatically locked between described joint a of present embodiment and the connecting sleeve b comprises the V-shaped groove 17 of the adapter sleeve 4 right outer ends that are positioned at joint a with trip gear, and the ball 8 on the connecting sleeve b, connection overcoat 13, outer casing spring 12, thrust slide block 14 and interior sleeve spring 10.Have through hole on the fittings body 9, ball 8 is embedded in the through hole, and the ball outside is with and connects overcoat 13, connects between overcoat 13 and the fittings body 9 to be pressed with outer casing spring 12, ball 8 inboards are with a thrust slide block 14, thrust slide block 14 be connected be pressed with between the block set 11 in sleeve spring 10.At fittings body 9 left ends one thrust spring 7 is arranged in addition.
