Description

BACKGROUND OF THE INVENTION
Field of the Invention

The present invention relates to an air connector for inflating air, and more particularly to an air connector structure of the air connector which is adapted to connect the Presta (French) valve and the Schrader (American) valve.

Description of the Prior Art

Conventional valves for tires contain a Presta (French) valve and a Schrader (American) valve, and the Presta (French) valve and the Schrader (American) valve have two air connectors, respectively. User has to purchase the two air connectors to cause using inconvenience and high using cost.

The inventor of the present invention invented an air connector structure of the air connector which is adapted to connect the Presta (French) valve and the Schrader (American) valve and is disclosed in TW Patent Publication 1498479. The air connector is not replaced and is not operated complicatedly, but when it mates with the Schrader (American) valve to inflate air, inner threads of a Schrader (American) inserting hole of the air connector screw with outer threads of the Schrader (American) valve so that an opening of the Schrader (American) valve is pushed to open, thus inflating the air inconveniently and wasting using time. Furthermore, connection manners of the Schrader (American) valve and the Presta (French) valve are different to cause using confusion.

To improve above-mentioned problems, a quick air connector structure of an air connector is disclosed in TW Patent Publication 1544147 and contains a Presta (French) retainer configured to retain the Presta (French) valve, and the quick air connector structure contains a Schrader (American) retainer configured to retain the Schrader (American) valve so as to eliminate screwing time of the air connector and the Schrader (American) valve and to operate the air connector easily. However, when the air connector mates with the Schrader (American) valve, an operation ring is rotated so as to press a fixing element, the fixing element moves into an accommodation groove of a pushing needle to fix the pushing needle, and the Schrader (American) valve inserts into the air connector, thus having using inconvenience and long using time. The operation ring is rotated before the air connector is in connection with the Schrader (American) valve, so connecting operations of the Schrader (American) valve and the Presta (French) valve are different to cause using confusion.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

The two fixing blocks 40 are accommodated and move in the two receiving orifices 122 individually so as to enter into or go away from the Presta (French) inserting hole 12, and each of the two fixing blocks 40 includes an abutting segment 41 formed on a first end of each fixing block 40 corresponding to the Presta (French) inserting hole 12. Each fixing block 40 also includes a third locking segment 42 formed on a second end thereof, and between each fixing block 40 and the body 10 is defined a third push spring 43 configured to push each fixing block 40 away from the Presta (French) inserting hole 12.

The control set 50 is disposed on the body 10 and controls the first limiting segment 22 of each Schrader (American) retainer 20, the second limiting segment 32 of each Presta (French) retainer 30, and the third limiting segment 42 of each fixing block 40, such that the first locking segment 21 and the multiple first locking teeth 21A of each Schrader (American) retainer 20 move in or away from the Schrader (American) inserting hole 11, the second locking segment 31 and the multiple second locking teeth 31A of each Presta (French) retainer 30 move in or away from the Presta (French) inserting hole 12, and the abutting segment 41 of each fixing block 40 moves in or away from the Presta (French) inserting hole 12. The control set 50 is a rotatable ring and is fitted with the body 10. The control set 50 includes a first press protrusion 51, a second press protrusion 52, and two trenches 521 defined on the second press protrusions 52. The control set 50 also includes two slide rails 16 formed on two connection areas of the two trenches 521 and the body 10 so that the two trenches 521 slide along the two slide rails 16. When the two trenches 521 slide away from the two slide rails 16, the control set 50 is rotated so as to drive the second press protrusion 52 to stop the two slide rails 16. The control set 50 controls the first press protrusion 51 to stop the first limiting segment 22 of each Schrader (American) retainer 20, after the first limiting segment 22 moves. The control set 50 controls the second press protrusion 52 to stop the second limiting segment 32 of each Presta (French) retainer 30, after the second limiting segment 22 moves. Furthermore, the control set 50 controls the second press protrusion 52 to stop the third limiting segment 42 of each fixing block 40, after the third limiting segment 42 moves.

The movable post 60 is mounted in and is limited by the Presta (French) inserting hole 12 and the accommodation groove 13 of the body 10, and the movable post 60 includes a positioning slot 61 and a biasing segment 62 corresponding to the Schrader (American) inserting hole 11, such that the movable post 60 allows the air flowing therethrough. The biasing segment 62 corresponds to the Schrader (American) inlet part 2B, and the positioning slot 61 of the movable post 60 and two abutting segments 41 of the two fixing blocks 40 have a pushing structure. In this embodiment, the pushing structure is two tilted faces 611, 411. When the two abutting segments 41 of the two fixing blocks 40 move into the Presta (French) inserting hole 12, the pushing structure drives the movable post 60 to move toward the Schrader (American) inserting hole 11 by using component of force, and when the two abutting segments 41 of the two fixing blocks 40 move into the positioning slot 61 of the movable post 60, the movable post 60 is positioned. The movable post 60 further includes a slidable rib 63 arranged on a peripheral side thereof, the Presta (French) inserting hole 12 and the accommodation groove 13 of the body 10 have a trough 17 matching with the slidable rib 63, hence when the movable post 60 is controlled to move, the slidable rib 63 slides in the trough 17 so as to stop the movable post 60.

The forcing spring 70 is defined between the accommodation groove 13 of the body 10 and the movable post 60.

The accommodation groove 13 of the body 10 has a first shoulder 18 proximate to the Presta (French) inserting hole 12, and the movable post 60 includes a second shoulder 64 formed thereon, such that when the movable post 60 moves in the accommodation groove 13 and the second shoulder 64 abuts against the first shoulder 18, the movable post 60 does not move toward the Schrader (American) inserting hole 11.

When the air connector 1 is in connection with the Schrader (American) valve 2 to inflate the air, as shown in FIGS. 5 to 7, the Schrader (American) valve 2 is coupled to the Schrader (American) inserting hole 11 of the body 10 and presses the airtight washer 15 which is fixed between the Schrader (American) inserting hole 11 and the Presta (French) inserting hole 12 so that the Schrader (American) threads 2A align with the multiple first locking teeth 21A of each Schrader (American) retainer 20, and the Schrader (American) valve 2 and the Schrader (American) inserting hole 11 are airproofed by the airtight washer 15, wherein the movable post 60 is pushed a distance D1 toward the accommodation groove 13 so as to press the forcing spring 70, hence the positioning slot 61 of the movable post 60 aligns with the two abutting segments 41 of the two fixing blocks 40. Referring to FIGS. 8 to 10, when the control set 50 slides on the body 1 so that the first limiting segment 22 of each Schrader (American) retainer 20 is pressed and limited by the first press protrusion 51 of the control set 50, each Schrader (American) retainer 20 is controlled to move into the Schrader (American) inserting hole 11, and the multiple first locking teeth 21A of each Schrader (American) retainer 20 engage with the Schrader (American) threads 2A of the Schrader (American) valve 2, thus fixing the Schrader (American) valve 2. In the meantime, the second press protrusion 52 of the control set 50 is biased against and limits the two fixing blocks 40 so that the two fixing blocks 40 move toward and are fixed in the Presta (French) inserting hole 12. The component of force pushes the movable post 60 toward the Schrader (American) inserting hole 11 by using the two tilted faces 611, 411 of the pushing structure so that the Schrader (American) inlet part 2B of the Schrader (American) valve 2 is pressed by the movable post 60 to open, and when the two abutting segments 41 of the two fixing blocks 40 move into the positioning slot 61 of the movable post 60, they fix the movable post 60, hence the air is inflated into the Schrader (American) valve 2 via the air connector 1.

As the air connector 1 is connected with the Presta (French) valve 3, as illustrated in FIG. 11, the Presta (French) valve 3 is coupled to the Presta (French) inserting hole 12 of the body 10 so as to push the movable post 60 toward the accommodation groove 13, hence the movable post 60 presses the forcing spring 70 so that the movable post 60 removes from the Presta (French) inserting hole 12, the Presta (French) threads 3A align with the multiple second locking teeth 31A of each Presta (French) retainer 30, and the outer peripheral side of the Presta (French) valve 3 engages with the airtight washer 15 to as to form an airtight state. Referring further to FIG. 12, the control set 50 is slid on the body 10 so that the second limiting segment 32 of each Presta (French) retainer 30 is pressed and limited by the second press protrusion 52 of the control set 50, and each Presta (French) retainer 30 is controlled to move and fix in the Presta (French) inserting hole 12, hence the multiple second locking teeth 31A of each Presta (French) retainer 30 engage with the Presta (French) threads 3A of the Presta (French) valve 3, thus positioning the Presta (French) valve 3. Thereafter, the Presta (French) inlet part 3B is opened by a pressure as inflating the air so that the air is inflated into the Schrader (American) valve 2 via the air connector 1.

When the spring 70 is not used, the movable post 60 is urged by a force to move toward the Schrader (American) inserting hole 11, wherein the force is pneumatic force.

The body 10 is comprised of a first part 10A, a second part 10B, and a third part 10C, wherein the first part 10A is in connection with the second part 10B, the second part 10B is coupled with the third part 10C, and connection of the first part 10A and the second part 10B is obtained in a right-angle turning manner. The air intake 14 is defined on the first part 10A. The accommodation groove 13, the Presta (French) inserting hole 12, the two second through orifices 121, and the two receiving orifices 122 are arranged on the second part 10B, the Schrader (American) inserting hole 11 is defined between the second part 10B and the third part 10C, and the two first through orifices 111 are formed on the third part 10C.

After the air connector 1 is connected with the Schrader (American) valve 2, it is manually rotated based on Schrader (American) valve 2 of various sizes so that the Schrader (American) threads 2A of the Schrader (American) valve 2 mate with the multiple first locking teeth 21A of each Schrader (American) retainer 20 to move toward the accommodation groove 13, hence the air connector 1 is connected with the Schrader (American) valve 2 in an optimal connection position.

The connector structure of the air connector of the present invention has advantages as follows:

the connector structure of the air connector 1 is adapted to valves of two sizes, for example, one end of the air connector 1 is adapted to connect the Presta (French) valve 2 and the Schrader (American) valve simultaneously so as to inflate the air, and the control set 50 slides as operating the air connector 1 to press each Schrader (American) retainer 20, each Presta (French) retainer 30, and the two fixing blocks 40. Accordingly, the air connector 1 is connected with the Presta (French) valve 2 or the Schrader (American) valve easily and clearly.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
