Abstract

A valve connector suitable for a Presta valve comprises a housing and a clamping device. The housing is provided with a sliding slot along a reference longitudinal axis. The clamping device is positioned within the sliding slot and includes a pushing seat and at least one engaging member. The pushing seat is provided with a valve insertion hole along an axial direction of the reference longitudinal axis. The pushing seat further has at least one accommodating slot, in which the engaging member is movably arranged along a reference line. The reference line forms an oblique angle with the reference longitudinal axis, and the angle is less than 90 degrees. When the clamping device is in a clamping position, the engaging member is close to the reference longitudinal axis. When the clamping device is in a release position, the engaging member is farther from the reference longitudinal axis. This structure makes the operation convenient and provides a good clamping effect.

Description

Suitable for Presta valve connector

The present invention mainly discloses a connector, particularly a connector suitable for Presta valves.

Please refer to Taiwan's patent No. M641881, "Press-button anti-retraction type air nozzle connector structure", which is a press-button anti-retraction type air nozzle connector structure, including a main body and two press-button devices; the main body has two external joint surfaces respectively combined with press-button devices, each press-button device is provided with an integrally formed buckle and an embedded protruding button; thereby, When the button is pressed by external force, the buckle teeth of the buckle member can be driven to withdraw 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 buckle teeth of the buckle member can be restored to the channel of the main body, so that the two buckle teeth of the two buckle devices are respectively clamped on the outer sides of the tire valve.

However, the aforementioned valve connector requires pressing the snap-on device whenever the valve is inserted or removed, and both snap-on devices must be pressed simultaneously with two fingers to complete the operation. This is not only inconvenient to operate, but also, when the thrust of the high-pressure air drives the valve backward, the backward force of the valve generates a radial component of force on the contact surface between the snap-on device and the valve, which may cause the snap-on device to unfold and detach from the valve due to the pressure of the valve.

When the clamping device 30 is in the release position, the two clamping members 32 are away from the virtual axis L.

The receiving groove 312 extends axially along the base line B1. One end of the receiving groove 312 is connected to the air nozzle insertion hole 311 and the other end is connected to the outer periphery of the push seat 31. The two receiving grooves 312 are respectively disposed on opposite sides of the push seat 31.

The front baffle 34 is fixedly coupled to the inner periphery of the slide groove 21. The end of the push seat 31 adjacent to the first end 22 is inserted into the front baffle 34. The opposite ends of the clamping member 32 protrude from the accommodating groove 312 and respectively abut against the baffle portion 341. The clamping portion 321 is disposed between the two ends of the clamping member 32. When the clamping device 30 is in the clamping position, the clamping portion 321 protrudes into the valve insertion hole 311.

The clamping device 30 includes an elastic member 35, which is sleeved on the outer periphery of the push seat 31. One end of the elastic member 35 pushes the push seat 31 and the other end pushes the clamping member 32 to protrude from the side of the accommodating groove 312 adjacent to the second end 23. The elastic member 35 provides a thrust to keep the clamping member 32 in contact with the baffle portion 341.

The fastening portion 321 is in the shape of a square rod, and the tooth 322 is disposed on a side of the fastening portion 321 adjacent to the valve insertion hole 311 . The two ends of the fastening member 32 protruding from the receiving groove 312 are both in the shape of round rods.

The clamping device 30 includes a rear cover 36, which is connected to the end of the push seat 31 opposite to the first end 22 and protrudes from the second end 23. When the clamping device 30 is in the clamping position, the push seat 31 and the rear cover 36 move synchronously toward the second end 23. When the clamping device 30 is in the release position, the push seat 31 and the rear cover 36 move synchronously toward the first end 22.

An annular protrusion 211 is provided around the inner periphery of the slide groove 21 with the virtual axis L as the center. The push seat 31 is provided between the annular protrusion 211 and the first end 22, and the rear cover 36 is provided between the annular protrusion 211 and the second end 23. When the clamping device 30 is in the clamping position, the push seat 31 contacts the end of the annular protrusion 211 adjacent to the first end 22. When the clamping device 30 is in the release position, the rear cover 36 contacts the end of the annular protrusion 211 adjacent to the second end 23.

The housing 20 is radially provided with a side channel 24 along the virtual axis L. The side channel 24 is connected to the slide groove 21 and is disposed between the first end 22 and the second end 23 .

The connector 10 is easy to operate and has a good clamping effect through the above structure. When using the connector 10, the Presta valve 90 can be directly inserted into the valve socket 311. The Presta valve 90 can push the clamping portion 321 apart. After the Presta valve 90 is inserted between the two clamping members 32, it will be clamped by the clamping portion 321 and cannot be disengaged. If the Presta valve 90 is pulled out in the opposite direction, the two clamping members 32 will be clamped tighter. The curved tooth 322 increases the contact area and achieves a better engagement effect. To remove the Presta valve 90, the outer housing 20 is grasped and the rear cover 36 is pressed, causing the clamping device 30 to move to the release position. The front blocking ring 34 pushes the clamping member 32 away, allowing the Presta valve 90 to be pulled out.
