Description

Connector suitable for various valves

The present invention primarily discloses a connector, particularly a connector suitable for various valves.

Please refer to Chinese Patent No. M641881, "A Press-fit Anti-reverse Type Air Nozzle Connector Structure," which describes a press-fit anti-reverse type air nozzle connector structure, including a main body and two press-fit devices. The main body has two external mating surfaces respectively joined with the press-fit devices. Each press-fit device has an integrally formed latching element and a protruding button embedded inside. Therefore, When the button is pressed by external force, the locking teeth of the locking device can be disengaged from the channel of the main body, allowing the tire valve to be inserted into the channel of the main body; when the button is not pressed by external force, the locking teeth of the locking device return to the channel of the main body, causing the two locking teeth of the two pressing devices to clamp onto the two outer sides of the tire valve respectively.

However, the aforementioned valve connector requires pressing the snap-fit device when inserting or removing the valve, and two snap-fit devices must be pressed simultaneously with two fingers to complete the operation. This is not only cumbersome, but also causes the valve to retract due to the thrust of the high-pressure air. The backward force of the valve will generate a radial component force at the contact surface between the snap-fit device and the valve, which may cause the snap-fit device to unfold and detach from the valve due to the pressure of the valve.

In view of the shortcomings of the above-mentioned conventional structures, the inventors have designed a connector applicable to a variety of valves, which can overcome all the shortcomings of the above-mentioned conventional structures.

The present invention is applicable to various valve connectors. Its main objective is to provide a connector comprising a housing and a clamping device. The housing has a groove along a virtual through-axis. The housing has a first end and a second end opposite to the first end along the through-axis. The groove extends from the first end to the second end. The clamping device is disposed within the groove and includes a push base and at least one jaw. The push base is adjacent to the first end and has a valve insertion hole along the through-axis. The push base has at least one receiving... The connector has a slot, in which at least one jaw is disposed. The jaw includes a pivot seat and a clamping arm. The pivot seat has a first pivot, and the clamping arm is pivotally disposed on the pivot seat. The clamping arm has a clamping portion. The clamping device is slidable between a clamping position and a releasing position. When the clamping device is in the clamping position, the clamping portion and the first pivot are close to the through shaft. When the clamping device is in the releasing position, the clamping portion and the first pivot are away from the through shaft. The connector has the above structure to make operation convenient and clamping effect good.

The inner periphery of the slide is provided with a push surface adjacent to the first end. The pivot seat is provided with a second pivot, which is pivotally located on the push seat. When the clamping device is in the release position, the first pivot disengages from the push surface and moves the clamping part away from the shaft. When the clamping device is in the clamping position, the first pivot contacts the push surface and moves the clamping part closer to the shaft.

The first pivot portion forms a first depth along the axial direction of the penetrating axis to the first end, and the clamping portion forms a second depth along the axial direction of the penetrating axis to the first end. The first depth is less than the second depth. The clamping device slides between the release position and the clamping position, which allows the jaw to rotate relative to the push base.

The second hub forms a third depth along the axial direction of the axis to the first end, and the third depth is greater than the second depth.

The clamping device includes at least one elastic element, which is a torsion spring and is disposed in the first pivot. The two ends of the at least one elastic element push against the pivot seat and the clamping arm, respectively.

The push base is provided with at least one pin, which is connected to the push base by a plug-in connection. The pin is inserted into the receiving groove, and the second pivot is sleeved on the pin and pivotally mounted on the push base with the pin as the center.

The push surface is arranged around the inner periphery of the slide groove with the central axis as the center. The clamping device includes three clamping jaws. The push base has three receiving slots, which are connected to the air nozzle insertion holes. The three clamping jaws are respectively disposed in the three receiving slots. The clamping device includes three elastic elements. Each of the three jaws has a first pivot, and the push base has three pins. The three pins are connected to the push base by a plug-in connection. The three pins are inserted into the three receiving slots. Each of the three jaws has a first pivot sleeved on the three pins and pivoted on the push base with each pin as the center.

The clamping device includes a back cover that is screwed to the pusher. When the clamping device is in the clamping position, the pusher and the back cover move synchronously toward the second end, and the back cover protrudes from the second end of the outer shell. When the clamping device is in the releasing position, the pusher and the back cover move synchronously toward the first end, and the pusher protrudes from the first end of the outer shell.

The inner periphery of the slide is provided with a limiting flange. The American-style pusher is disposed between the limiting flange and the first end, and between the limiting flange and the second end. When the clamping device is in the released position, the American-style pusher contacts the end of the limiting flange near the first end. When the clamping device is in the clamping position, the pusher contacts the end of the limiting flange near the second end.

Other objectives, advantages, and novelty of the invention will become more apparent from the following detailed description and accompanying figures.

When the clamping device 30 is in the clamping position, the clamping part 324 and the first pivot 323 are close to the through shaft L. When the clamping device 30 is in the releasing position, the clamping part 324 and the first pivot 323 are far away from the through shaft L.

The inner periphery of the slide groove 21 is provided with a push surface 211 adjacent to the first end 22. The pivot seat 321 is provided with a second pivot 325, which is pivotally located on the push seat 31. When the clamping device 30 is in the release position, the first pivot 323 disengages from the push surface 211 and causes the clamping part 324 to move away from the through shaft L. When the clamping device 30 is in the clamping position, the first pivot 323 contacts the push surface 211 and causes the clamping part 324 to move closer to the through shaft L.

The first pivot 323 forms a first depth D1 along the axial direction of the penetrating axis L to the first end 22, and the clamping part 324 forms a second depth D2 along the axial direction of the penetrating axis L to the first end 22. The first depth D1 is less than the second depth D2. The clamping device 30 can slide between the release position and the clamping position to allow the jaw 32 to rotate relative to the push base 31.

The second hub 325 forms a third depth D3 along the axial direction of the penetrating axis L to the first end 22, and the third depth D3 is greater than the second depth D2.

The clamping device 30 includes at least one elastic element 33, which is a torsion spring and is disposed in the first pivot 323. The two ends of the at least one elastic element 33 push against the pivot seat 321 and the clamping arm 322 respectively.

The push base 31 is provided with at least one pin 313, which is connected to the push base 31 by a plug-in connection. The pin 313 is inserted into the receiving groove 312. The second pivot 325 is sleeved on the pin 313 and pivotally mounted on the push base 31 with the pin 313 as the center.

The push surface 211 is arranged around the inner periphery of the slide groove 21 with the through shaft L as the center. The clamping device 30 includes three clamping jaws 32. The push base 31 has three receiving grooves 312, which are connected to the air nozzle insertion hole 311. The three clamping jaws 32 are respectively disposed in the three receiving grooves 312. The clamping device 30 includes three elastic members 33, which are respectively Each of the three jaws 32 has a first pivot 323 disposed thereon. The push base 31 is provided with three pins 313. The three pins 313 are connected to the push base 31 by a plug-in connection. The three pins 313 are respectively inserted into the three receiving slots 312. Each of the three jaws 32 has a first pivot 323 sleeved on the three pins 313 and pivotally mounted on the push base 31 with each pin 313 as the center.

The clamping device 30 includes a back cover 34, which is screwed to the push base 31. When the clamping device 30 is in the clamping position, the push base 31 and the back cover 34 move synchronously toward the second end 23, and the back cover 34 protrudes from the second end 23 out of the outer shell 20. When the clamping device 30 is in the releasing position, the push base 31 and the back cover 34 move synchronously toward the first end 22, and the push base 31 protrudes from the first end 22 out of the outer shell 20.

The inner periphery of the slide 21 is provided with a limiting flange 212. The American-style pusher 31 is disposed between the limiting flange 212 and the first end 22. The pusher 31 is disposed between the limiting flange 212 and the second end 23. When the clamping device 30 is in the released position, the American-style pusher 31 contacts the end of the limiting flange 212 near the first end 22. When the clamping device 30 is in the clamping position, the pusher 31 contacts the end of the limiting flange 212 near the second end 23.

The connector 10, through the aforementioned structure, facilitates operation and provides excellent clamping performance. When using the connector 10, the French nozzle 90 can be directly inserted into the nozzle socket 311. When the clamping device 30 is in the clamping position, the French nozzle 90 will be clamped by the clamping part 324 and cannot be detached. If the French nozzle 90 is pulled out in the opposite direction, the clamping part 324 will clamp even tighter. To remove the French nozzle 90, you can grasp the outer shell 20 and press the back cover 34 to move the clamping device 30 to the release position. The first pivot 323 will be released from the restriction of the first push surface 211. When the French nozzle 90 is pulled out, the French nozzle 90 pushes the clamping part 324 to make the claw 32 retract, thus allowing the French nozzle 90 to be pulled out.
