Description

Wind nozzle

This creation mainly discloses a nozzle head, especially a nozzle head that only needs a single airtight component to achieve airtightness.

Please refer to the patent case of "Press-lock anti-retractable air nozzle joint structure" of Taiwan Patent No. M641881, which is a press-lock anti-retractable air nozzle joint structure, including a main body and two press-lock devices; the main body has two external joint surfaces respectively combined with press-lock devices, and each press-lock device has an integrally formed buckle and a protruding button embedded therein; 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; and when the button is not pressed by external force, the buckle teeth of the buckle member are 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the above-mentioned gas nozzle connector requires pressing the buckle device when the gas nozzle is inserted or withdrawn, and the two buckle devices must be pressed simultaneously with two fingers to complete the operation. Not only is the operation inconvenient, but also when the thrust of the high-pressure air drives the gas nozzle backward, the backward force of the gas nozzle will generate a radial component force on the contact surface between the buckle device and the gas nozzle, so that the buckle device may be expanded and separated from the gas nozzle due to the squeezing of the gas nozzle.

In view of the defects of the above-mentioned learned structure, the author has designed a tuyere head which can overcome all the defects of the above-mentioned learned structure.

One end of the elastic member pushes the convex portion and the other end pushes the clamping member to protrude from one side of the two ends of the accommodating groove adjacent to the second end. The elastic member provides a thrust to keep the clamping member in contact with the front stop.

One end of the inner periphery of the slide groove adjacent to the second end is connected to a rear cover. When the clamping device is in the clamping position, the push seat moves toward the direction adjacent to the second end and abuts against the rear cover. When the clamping device is in the releasing position, the push seat moves toward the direction adjacent to the first end and separates from the rear cover.

The clamping device 30 is disposed in the slide groove 23. The clamping device 30 includes a push seat 31, at least one clamping member 32 and an airtight member 33. The push seat 31 has an end adjacent to the first end 21 and an air nozzle plug hole 311 axially arranged along the through axis L, and the other end protrudes from the second end 22 and is provided with an air inlet 312. The air inlet 312 is connected to the air nozzle plug hole 311. The push seat 31 is provided with at least one accommodating groove 313. The clamping member 32 can be movably arranged along a virtual reference line B. Placed in the accommodating groove 313, an oblique angle A is formed between the reference line B and the side of the through-axis L adjacent to the second end 22, and the oblique angle A is less than 90 degrees. The clamping device 30 can slide between the clamping position and the release position. When the clamping device 30 is in the clamping position, the fastening member 32 is close to the through-axis L. When the clamping device 30 is in the release position, the fastening member 32 contacts the front stopper 231 and makes the fastening member 32 away from the through-axis L. The airtight member 33 is annular and is arranged in the air nozzle socket 311.

The push seat 31 has an annular recess 314 formed on the inner periphery of the air nozzle insertion hole 311 . The annular recess 314 is disposed on a side of the air inlet 312 adjacent to the second end 22 . The airtight member 33 is disposed in the annular recess 314 .

The clamping device 30 includes two clamping members 32, and the push seat 31 is provided with two accommodating grooves 313. The two clamping members 32 are movably arranged in the two accommodating grooves 313 respectively. When the clamping device 30 is in the clamping position, the two clamping members 32 are close to the through-axis L. When the clamping device 30 is in the releasing position, the two clamping members 32 are far away from the through-axis L.

The receiving groove 313 extends axially along the reference line B, one end of the receiving groove 313 is connected to the air nozzle socket 311 and the other end is connected to the outer periphery of the push seat 31, the two clamping members 32 and the two receiving grooves 313 are symmetrically arranged on opposite sides of the push seat 31, and the opposite ends of the clamping member 32 protrude from the receiving groove 313 and respectively abut against the front stopper 231. The clamping member 32 is provided with a clamping portion 321, and the clamping portion 321 is arranged 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 air nozzle socket 311.

The fastening portion 321 is in the shape of a square rod, and the two ends of the fastening member 32 protruding from the receiving groove 313 are in the shape of round rods.

The push seat 31 is provided with a protrusion 315 along the outer periphery of the radial direction of the through axis L. The clamping device 30 includes an elastic member 34, which is sleeved on the outer periphery of the push seat 31. One end of the elastic member 34 pushes the protrusion 315 and the other end pushes the clamping member 32 to protrude from one side of the two ends of the accommodating groove 313 adjacent to the second end 22. The elastic member 34 provides a thrust to keep the clamping member 32 in contact with the front stop 231.

An end of the inner periphery of the slide groove 23 adjacent to the second end 22 is connected to a rear cover 232. When the clamping device 30 is in the clamping position, the push seat 31 moves toward the direction adjacent to the second end 22 and abuts against the rear cover 232.
