Description

Air nozzle connector

The novel invention provides a gas nozzle connector that can be connected or disconnected from the gas nozzle by one-hand operation.

The general air pump nozzle, as shown in the Republic of China's new patent No. M318073, has a nozzle head with a connected assembly hole and a pipe. The top of the assembly hole is equipped with a wrench, and the bottom is equipped with a nozzle for inserting and positioning an American nozzle. The assembly hole is equipped with a clamp at the top of the nozzle for inserting a French nozzle. The top of the clamp is equipped with a downward-contracting guide. Hole, and then an injection machine is slidably fitted between the clamp and the wrench. A return spring is provided between the injection machine and the clamp, and a movable claw corresponding to the guide hole is provided at the bottom of the injection machine. A spring is connected to a ejector in the injection machine, so that when the wrench drives the injection machine to move downward, the movable claw can force the air nozzle to deform and clamp the American/French nozzle, so that the ejector can be inflated securely.

However, when using the above-mentioned air pump nozzle, the operation process is relatively cumbersome. The user must first insert the nozzle of the inflatable object into the nozzle head, and then pull up the wrench to force the nozzle to clamp the nozzle of the inflatable object. Therefore, the user needs to use both hands to control the positions of the nozzle of the inflatable object, the nozzle head and the wrench at the same time, which makes the operation process quite inconvenient.

The novel invention provides a gas nozzle connector that can be operated with one hand to facilitate connecting or disconnecting the gas nozzle.

The novel inventive embodiment proposes a gas nozzle joint, including a housing, a clamping device, a lever, a driving member and a biasing member.

Please refer to Figures 1 to 4 in sequence, which show the appearance, decomposition and cross-sectional schematic diagrams of an embodiment of the novel gas nozzle connector. The gas nozzle connector of this embodiment includes a housing 10, a clamping device 20, a lever 30, a driving member 40 and a biasing member 50.

The housing 10 has a connection end 11 and an operating end 12, and is provided with a receiving hole 13, a hinge 14, a stopper 15 and an air passage 16. The receiving hole 13 extends from the connection end 11 to the operating end 12 along an axis A10, the hinge 14 is located at the operating end 12 and connected to the receiving hole 13, the stopper 15 is provided at the connection end 11, and the air passage 16 can be connected to an air pump (not shown). The housing 10 can also include a cover 17, which is screwed to the connection end 11 and forms the stopper 15, and the stopper 15 extends inward toward the axis A10.

The clamping device 20 includes a soft airtight ring 21, an injector 22, a clamp 23 and an elastic member 24. The airtight ring 21 is disposed between the stopper 15 and the injector 22 and can be squeezed by the injector 22 to clamp the gas nozzle (not shown). Further, one end of the airtight ring 21 abuts against the stopper 15, and the other end abuts against the injector 22. The injector 22 is movably disposed in the receiving hole 13 and penetrates the airtight ring 21, and the injector 22 is movably connected to the clamp 23 along the axis A10 and can abut against the gas nozzle. The elastic member 24 elastically abuts between the injector 22 and the clamp 23.

The lever 30 has a pivoting portion 31 and a pressing portion 32. The pivoting portion 31 is pivoted to the pivoting groove 14 of the housing 10, and the pressing portion 32 extends from the pivoting portion 31 toward the driving member 40. The clamp 23 can be pressed against the pivoting portion 31 to drive the injection molding machine 22 to move along the axis A10 and squeeze the airtight ring 21, so that the airtight ring 21 is elastically deformed to clamp the gas nozzle. Furthermore, the hinge portion 31 is provided with a first abutting surface 311 and a second abutting surface 312 . The first abutting surface 311 and the second abutting surface 312 are adjacent to each other and form an abutting angle 313 . The first abutting surface 311 and the abutting angle 313 can selectively abut the clamp 23 .

The driving member 40 is pivoted to the pivot groove 14 of the housing 10 and is configured to drive the lever 30 to pivot relative to the housing 10. To this end, the driving member 40 has a driving portion 41 and a linking portion 42 extending from the driving portion 41, and the linking portion 42 is configured to drive the pressing portion 32 of the lever 30 to pivot relative to the housing 10 when the driving portion 41 is driven by an external force and causes the driving member 40 to pivot relative to the housing 10. Therefore, the pressing portion 32 and the linking portion 42 maintain contact.

The biasing member 50 is disposed between the housing 10 and the driving member 40 to bias the driving member 40. Further, the biasing member 50 can be a torsion spring and is disposed in the hinge 14 to bias the driving portion 41 of the driving member 40.

In order to pivot the lever 30 to the pivot groove 14 of the housing 10, the valve joint further includes a first pivot 60 penetrating the pivot portion 31. There is a first distance D1 between the axis of the first pivot 60 and the first abutting surface 311, and there is a second distance D2 between the axis of the first pivot 60 and the second abutting surface 312, and the second distance D2 is smaller than the first distance D1.

In order to pivot the driving member 40 to the hinge 14 of the housing 10 , the air nozzle joint further includes a second pivot 70 passing through the driving member 40 , so that the driving member 40 is configured to pivot with the axis of the second pivot 70 relative to the hinge 14 to drive the lever 30 .

As shown in FIG. 3 , the driving member 40 is in the locked position, the linkage portion 42 of the driving member 40 contacts the pressing portion 32 of the lever 30, the first abutting surface 311 of the hinge portion 31 abuts against the clamp 23, and the injector 22 applies pressure to the airtight ring 21, so that the airtight ring 21 is in a compressed state to clamp the gas nozzle.

As shown in FIG4 , the user can apply force to press the driving portion 41 of the driving member 40, the biasing member 50 is compressed and the driving member 40 pivots relative to the hinge 14, so that the driving member 40 changes from the locked position to the released position. At this time, the linking portion 42 of the driving member 40 drives the pressing portion 32 of the lever 30, so that the lever 30 pivots relative to the hinge 14, the abutting angle 313 abuts against the clamp 23, and the airtight ring 21 changes from the compressed state to the restored state, so that the airtight ring 21 is separated from the gas nozzle, and the gas nozzle can be separated from the gas nozzle joint.

It can be understood that when the gas nozzle is detached from the gas nozzle connector, the user can press the pressing portion 32 of the lever 30 to make the pressing portion 32 push against the linkage portion 42 of the driving member 40, and the lever 30 and the driving member 40 swing synchronously until the driving member 40 changes from the release position to the locking position.

In summary, the above-mentioned embodiment of the present invention controls the lever 30 by pressing the driving member 40 with one hand, so that the airtight ring 21 can be switched between the compression state and the recovery state, thereby realizing the clamping and disengagement functions of the air nozzle.
