[background technology]

Along with being on the increase of inflation appliance, the kind of thing followed charging connector is also more and more various, charging connector is for being inflated aerated product and exitting, and some charging connectors are due to the deficiency in structure, when venting, after taking away mouth cap, gas can leak outside, and is unfavorable for daily use, and some charging connector sealing properties are inadequate, actually used process will occur the phenomenon of gas leakage often, reduce the experience degree of aerated product greatly.

In order to ensure the long-term maintenance of aerated product internal gas, air tight, and after user takes away mouth cap, gas will not leak automatically, being easy to the gas flow from Row sum-equal matrix interiors of products, thus reaching to regulate the purpose of product global comfort, those skilled in the art has carried out substantial amounts of R&D work, internal structure for charging connector has been improved, and also achieves good effect.

[utility model content]

For overcoming the problem existing for prior art, this utility model provides a kind of practical, the charging connector of good airproof performance.

This utility model solves the scheme of technical problem and is to provide a kind of charging connector, including charging connector body, charging connector body includes charge valve, ventilation cavity and spring, one end of charge valve connects piston sheet, the other end extends to form extension laterally, and spring one end withstands extension, and the other end withstands the ventilation interlayer of ventilation inside cavity, under the effect of spring force, piston sheet fits tightly with ventilation cavity.

Preferably, described charge valve, through the centre bore of ventilation interlayer, realizes moving up and down under the restriction effect of centre bore.

Preferably, the internal diameter of described ventilation cavity is less than the diameter of piston sheet.

Preferably, described ventilation interlayer offers multiple passage.

Preferably, described ventilation interlayer is arranged at the middle part of charging connector intracoelomic cavity.

Preferably, described charging connector is also included mouth cap, mouth cap and charging connector body and is connected by connector, and connector and mouth cap are formed in one.

Preferably, one end of described connector is set to circular, and annulus is set in the connection realizing connector and charging connector body on charging connector body.

Preferably, the quantity of described passage is three.

Preferably, described charging connector body and mouth cap are plastic cement material.

Preferably, the arranged outside of described mouth cap has lifting ear.

Compared with prior art, this utility model charging connector is by arranging piston sheet, and is controlled the position of piston sheet by spring, under normal operating condition, piston sheet is in the state of fitting tightly, good seal performance with ventilation cavity under the elastic force effect of spring, gas will not flow out, when needs are exitted, user only need to somewhat press the upper end of charge valve, and piston sheet realizes separating with ventilation cavity, gas can flow out, easy to use, simple in construction, effective.

Fig. 1 is the perspective view of this utility model charging connector.

Fig. 2 is the cross section structure schematic diagram of this utility model charging connector.

[detailed description of the invention]

For making the purpose of this utility model, technical scheme and advantage are clearly understood, below in conjunction with drawings and Examples, this utility model are further elaborated. Should be appreciated that specific embodiment described herein is used only for explaining this utility model, be not used to limit this utility model.

Refer to Fig. 1 and Fig. 2, this utility model charging connector 1 includes charging connector body 15, charging connector body 15 includes charge valve 151, ventilation cavity 152 and spring 153, one end of charge valve 151 connects piston sheet 157, the other end extends to form extension 1511 laterally, extension 1511 is withstood in spring 153 one end, the other end withstands ventilation ventilation interlayer 155 within cavity 152, under the effect of spring 153 elastic force, piston sheet 157 fits tightly with ventilation cavity 152, under normal operating condition, piston sheet 157 is in, under the elastic force effect of spring 153, the state of fitting tightly with ventilation cavity 152, good seal performance, gas will not flow out, when needs are exitted, user only need to somewhat press the upper end of charge valve 151, piston sheet 157 realizes separating with ventilation cavity 152, gas can flow out, easy to use, simple in construction, effective.

Charge valve 151, through the centre bore of ventilation interlayer 155, realizes moving up and down under the restriction effect of centre bore, and the operation of charge valve 151 is played restriction effect by centre bore, it can be ensured that stablizing of charge valve 151, improves experience degree.

The internal diameter of ventilation cavity 152 is less than the diameter of piston sheet 157, and piston sheet 157 covers all ventilation cavity 152, in a state of use, it is possible to play good sealing effectiveness.

Ventilation interlayer 155 offers multiple passage 1551. Passage 1551 is easy to the circulation of gas, and after piston sheet 157 separates with ventilation cavity 152, gas, from piston sheet 157 and inflow the gap of ventilation cavity 152, can flow out through passage 1551.

Preferably, ventilation interlayer 155 is arranged at the middle part of charging connector body 15 inner chamber.

Charging connector 1 is also included mouth cap 11, mouth cap 11 and charging connector body 15 and is connected by connector 13, and connector 13 and mouth cap 11 are formed in one. Mouth cap 11 covers on charging connector body 15, plays a protective role, and also can improve sealing.
