Description
Technical field
The invention belongs to gas nozzle connector appliance technology more particularly to a kind of gas nozzle connectors of quick assembling.
Background technology
For ease of flexible Application of the vacuum pump on vehicle, its Rapid matching and more structure choices are improved, was usually adopted in the past
Change product structure with mould development, and then realizes vehicle layout path demand.Current many products are all to pass through change
Mold changes product structure, so that whole flow process is more troublesome, and the period is longer, expends larger.So for
Product is subjected to modularization, without carrying out die adjustment, can quick-replaceable gas nozzle, realize flexible Application, tissue is quick, matching
Convenient, the requirement for reducing the risk of change is more and more urgent.
Invention content
It is an object of the invention to solve the problems, such as techniques discussed above, a kind of Quick replacing structure is provided, letter
Single reliable, sealing performance is high, and the gas nozzle connector of quick assembling easy to assembly, its technical solution is as follows：
The gas nozzle connector of quick assembling, which is characterized in that the end of quick assembling gas nozzle connector one end is provided with end
Mating surface, end mating surface are clearance fit with smooth mating surfaces；Groove is offered on quick assembling gas nozzle, and O is assembled in groove
Shape circle is provided with elastic card on quick assembling gas nozzle, and quick assembling gas nozzle stretches into cavity when connect with the pump housing, elastic card
It is inserted into back taper slot, boss is provided on the quick assembling gas nozzle, quick assembling gas nozzle is stretched into cavity and connect with the pump housing
When, boss is fastened in groove；The end of the quick assembling gas nozzle other end is provided with the connecting rod of quick assembling, connection
Bar be connected with quick assembling, anti-dropout step；Quick assembling gas nozzle is linear type shape.Two small boss are set, quick assembling is used for
Gas nozzle determines angle direction, and design flexibility card does not fall off convenient for being assembled in the pump housing, designs ditch shape annular groove, assembles O-ring, is used for
Sealing structure.O-ring is used for radial seal function, on the one hand end part seal ring seals, meanwhile, axial elastic force is provided,
The elastic card of quick assembling gas nozzle is set to ensure close-fitting with pump housing back taper slot always.
Preferred embodiment is that the thin rear end in elastic card front end is thick, and elastic card front end is inclined-plane.The inclined-plane of elastic card front end
Lower cavity and upper plenum are formed with wedge block when setting can make elastic card be inserted into back taper slot, so that elastic card
Front end have part be in contact with wedge block, due to the elastic reaction of elastic card so that the front end of elastic card is close to wedge block,
It is provided as using to play card.The upper plenum being formed simultaneously is communicated with through-hole, and since the front end of elastic card is inclined-plane, lead to bullet
Property card front end with wedge block be that part is connect, so when thering is tool to enter upper plenum from through-hole to contact with elastic card,
It can stir elastic card with smaller power to be detached from wedge block, to facilitate elastic card from back taper slot to deviate from.
The beneficial effects of the invention are as follows：Quick replacing structure implements flexible, simple and reliable, sealing performance height, assembly side
Just.
