Abstract

An inflator valve connector includes a housing, a connection assembly, a valve seat, and a pushing member. The connection assembly is rotatably arranged in the housing and includes a first connection hole adapted to connect a Presta valve and a second connection hole adapted to connect a Schrader valve. The valve seat has a first abutting portion faced to the first connection hole and adapted to abut a lock nut of the Presta valve, and a second abutting portion faced to the second connection hole and adapted to abut a valve core of the Schrader valve. The pushing member removably contacts the connection assembly and has a pushing portion adapted to enter the housing via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the housing and to close to the second connection hole.

First claim

The invention claimed is:

1. An inflator valve connector comprising:
a housing having a head, an axial hole arranged in the head, a body extended outwardly from the head, and a through hole arranged in the body and intercommunicated with the axial hole;
a connection assembly rotatably arranged in the axial hole and including a first connection hole adapted to threadedly connect a Presta valve, a second connection hole adapted to threadedly connect a Schrader valve, and a receiving hole intercommunicated with the first and second connection holes, wherein the first and second connection holes are screw holes;
a valve seat movably arranged in the receiving hole and having a first abutting portion disposed at a first end thereof and a second abutting portion disposed at a second end thereof opposite to the first end, wherein the first abutting portion is faced to the first connection hole and is adapted to abut a lock nut of the Presta valve, wherein the second abutting portion is faced to the second connection hole and is adapted to abut a valve core of the Schrader valve; and
a pushing member removably contacting the connection assembly and having a pushing portion adapted to enter the receiving hole via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the receiving hole and to close to the second connection hole, wherein the pushing member has a connection portion connected with the body, wherein the pushing member is made of a flexible material, so that the pushing portion is able to sway relative to the connection portion.

2. The inflator valve connector as claimed in claim 1 , wherein the first abutting portion forms an abutting recess adapted to abut the pushing portion and the lock nut of the Presta valve.

3. The inflator valve connector as claimed in claim 1 , wherein the connection portion is ring-shaped and is sleeved on the body.

4. The inflator valve connector as claimed in claim 1 , wherein the pushing member has a cover portion disposed between the pushing portion and the connection portion, wherein the pushing portion is formed on an end face of the cover portion, and wherein the cover portion covers the first connection hole when the pushing portion enters the receiving hole via the first connection hole.

5. The inflator valve connector as claimed in claim 4 , wherein the connection assembly includes a first connection member and a second connection member connected to the first connection member, wherein the first connection hole and the receiving hole are arranged in the first connection member, and wherein the second connection hole is arranged in the second connection member.

6. The inflator valve connector as claimed in claim 5 , wherein the connection assembly includes an air passage formed between an inner periphery of the axial hole and an outer periphery of the first connection member, wherein the first connection member has an air vent penetrating therethrough and intercommunicated with the air passage and the through hole, wherein an airtight ring is mounted around an outer periphery of the valve seat and is abutted against an inner periphery of the receiving hole, wherein the airtight ring is located between the air vent and the second connection hole when the pushing portion pushes against the first abutting portion and the valve seat closes to the second connection hole, and wherein the airtight ring passes over the air vent and is located between the air vent and the first connection hole when the second connection hole connects the Schrader valve and the second abutting portion is pushed by the valve core of the Schrader valve to cause the valve seat moving relative to the receiving hole and closing to the first connecting hole.

7. The inflator valve connector as claimed in claim 6 , wherein the first connection member has a first shoulder formed between the first connection hole and the receiving hole, wherein the second connection member has a second shoulder formed between the second connection hole and the receiving hole, wherein an airtight sleeve is mounted around the second abutting portion and abuts the inner periphery of the receiving hole, and wherein the first abutting portion and the airtight sleeve respectively selectively abut the first shoulder and the second shoulder as the valve seat moves relative to the receiving hole.

8. The inflator valve connector as claimed in claim 6 , wherein the first connection member has two annular grooves respectively formed at two opposite sides of the air vent, and wherein the connection assembly includes two seal rings respectively arranged in the two annular grooves and abutted against the inner periphery of the axial hole.

9. The inflator valve connector as claimed in claim 6 , wherein the first connection member has a large diameter section and a small diameter section connected to the large diameter section, wherein the large diameter section is exposed to the axial hole, wherein the small diameter section passes through the axial hole and is connected to the second connection member, wherein the first connection hole is formed in the large diameter section, wherein the receiving hole is formed in the small diameter section, and wherein the air passage is formed between the inner periphery of the axial hole and an outer periphery of the small diameter section.

10. An inflator valve connector comprising:
a housing having a head, an axial hole arranged in the head, a body extended outwardly from the head, and a through hole arranged in the body and intercommunicated with the axial hole;
a connection assembly rotatably arranged in the axial hole and including a first connection hole adapted to threadedly connect a Presta valve, a second connection hole adapted to threadedly connect a Schrader valve, and a receiving hole intercommunicated with the first and second connection holes, wherein the first and second connection holes are screw holes;
a valve seat movably arranged in the receiving hole and having a first abutting portion disposed at a first end thereof and a second abutting portion disposed at a second end thereof opposite to the first end, wherein the first abutting portion is faced to the first connection hole and is adapted to abut a lock nut of the Presta valve, wherein the second abutting portion is faced to the second connection hole and is adapted to abut a valve core of the Schrader valve; and
a pushing member removably contacting the connection assembly and having a pushing portion adapted to enter the receiving hole via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the receiving hole and to close to the second connection hole, and wherein the pushing member further has a connection portion connected with the body and integrally formed with the pushing portion.
