Abstract

A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

First claim

The invention claimed is:

1. A valve connector switchable between locking and releasing, comprising:
a housing including an operative end and a coupling end opposite to the operative end along a longitudinal axis of the housing, and wherein the housing includes a through-hole extending from the operative end through the coupling end along the longitudinal axis; and
a pressing device includes a push seat and a lever, wherein the push seat is received in the through-hole and is located between the lever and the coupling end, wherein the push seat includes a first passageway extending therethrough, wherein the lever is pivotably connected to the housing and is pivotable between a release position and a locking position, wherein the lever is adjacent to the operative end, wherein the lever abuts against the push seat and is operable to move the push seat along the longitudinal axis, wherein the lever includes a second passageway, wherein when the lever is in the release position, the first passageway does not intercommunicate with the second passageway, and the push seat is adjacent to the operative end, and wherein when the lever moves from the release position to the locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

2. The valve connector switchable between locking and releasing as claimed in claim 1 , wherein the housing includes a sleeve and a connector, wherein the sleeve includes the coupling end, wherein the connector is connected to the sleeve and includes the operative end, wherein the through-hole extends through the sleeve and the connector, and wherein the lever is pivotably connected to the connector.

3. The valve connector switchable between locking and releasing as claimed in claim 2 , wherein an inner periphery of the connector surrounding the through-hole includes a first coupling groove and a second coupling groove, wherein each of the first and second coupling grooves extends from an end of the connector adjacent to the sleeve towards but spaced from the operative end, wherein the first coupling groove and the second coupling groove are located on two opposite sides of the through-hole, respectively, wherein a first protrusion and a second protrusion are located on two opposite sides of the lever, respectively, wherein the first protrusion is received in the first coupling groove, and wherein the second protrusion is received in the second coupling groove.

4. The valve connector switchable between locking and releasing as claimed in claim 3 , wherein the connector is in threading connection with the sleeve.

5. The valve connector switchable between locking and releasing as claimed in claim 3 , wherein the pressing device includes an airtight ring disposed in the through-hole and adjacent to the coupling end, wherein the airtight ring abuts against an end of the push seat opposite to the lever, wherein when the lever is in the locking position, the push seat compresses and deforms the airtight ring, and wherein when the lever is in the release position, the airtight ring restores to its original shape and pushes the push seat towards the operative end.

6. The valve connector switchable between locking and releasing as claimed in claim 3 , wherein the first passageway includes a wider section and a narrower section, wherein the wider section is in an end of the push seat adjacent to the lever, wherein the narrower section is connected to an end of the wider section opposite to the lever, wherein an anti-leak ring is disposed in the wider section, wherein an end of the anti-leak ring abuts against an end face of the wider section adjacent to the narrower section, wherein another end of the anti-leak ring extends beyond the wider section and abuts against the lever, and wherein when the lever is in the locking position, the anti-leak ring abuts against an outer periphery of the lever.

7. The valve connector switchable between locking and releasing as claimed in claim 3 , wherein an end of the lever opposite to the push seat includes a coupling portion, wherein the lever includes a locking portion between two ends thereof, wherein the coupling portion has a width smaller than a width of the locking portion, wherein the lever is connected to a jacket in threading connection with the locking portion, and wherein the jacket surrounds but is spaced from the coupling portion.

8. The valve connector switchable between locking and releasing as claimed in claim 2 , wherein an inner periphery of the connector surrounding the through-hole includes a first insertion groove and a second insertion groove on two opposite sides of the through-hole, respectively, wherein each of the first insertion groove and the second insertion groove extends radially from an outer periphery of the connector to the through-hole, wherein the lever includes a third insertion groove extending therethrough in a direction perpendicular to the longitudinal axis, wherein the third insertion groove does not intercommunicate with the second passageway, wherein a pin extends through the first, second, and third insertion grooves, and wherein the lever is pivotable between the release position and the locking position about a pivotal axis defined by the pin.

9. The valve connector switchable between locking and releasing as claimed in claim 8 , wherein the connector is in threading connection with the sleeve.

10. The valve connector switchable between locking and releasing as claimed in claim 8 , wherein the pressing device includes an airtight ring disposed in the through-hole and adjacent to the coupling end, wherein the airtight ring abuts against an end of the push seat opposite to the lever, wherein when the lever is in the locking position, the push seat compresses and deforms the airtight ring, and wherein when the lever is in the release position, the airtight ring restores to its original shape and pushes the push seat towards the operative end.

11. The valve connector switchable between locking and releasing as claimed in claim 8 , wherein the first passageway includes a wider section and a narrower section, wherein the wider section is in an end of the push seat adjacent to the lever, wherein the narrower section is connected to an end of the wider section opposite to the lever, wherein an anti-leak ring is disposed in the wider section, wherein an end of the anti-leak ring abuts against an end face of the wider section adjacent to the narrower section, wherein another end of the anti-leak ring extends beyond the wider section and abuts against the lever, and wherein when the lever is in the locking position, the anti-leak ring abuts against an outer periphery of the lever.
