Definitions

  • the present invention relates to an aeration nozzle, and more particularly to an inflation nozzle for specifically inflating a French air nozzle. Background technique
  • the gas nozzle is generally disposed on an inflated object such as a tire of a vehicle; when an inflation is required, an inflator provided in the inflator of the gas pipe or an inflator of the inflator is connected to the nozzle, and the inflator can be operated to inflate the gas into the inflated air.
  • an inflator provided in the inflator of the gas pipe or an inflator of the inflator is connected to the nozzle, and the inflator can be operated to inflate the gas into the inflated air.
  • the air inlet of the air nozzle is provided with a gas valve ejector pin; when the gas valve ejector pin is not subjected to an external force, the air pressure inside the gas inflated body causes the gas valve to be in a sealed state to avoid gas leakage; When a force is applied to the ejector pin, the gas valve is opened, so that the inside of the inflated body communicates with the outside, so that the gas can be discharged outside the inflated object, or the gas can be charged into the inflated object.
  • the French gas nozzle has a structure different from that of the general gas nozzle.
  • the French air nozzle 5 has a two-stage thread (a first external thread 51 including a larger outer diameter, and a second outer thread 52 having a smaller outer diameter and close to the free end, the first external thread 51 A shoulder portion 53 is formed between the second external thread 52. Since there is no inflatable nozzle on the market that specifically cooperates with the French air nozzle, when the French air nozzle is to be inflated, the general inflation nozzle A must be combined with the adapter. B, and then the second external thread 52 of the French air nozzle 5 is locked by the internal thread B 1 provided on the adapter B (as shown in Fig. 7).
  • the inner diameter of the adapter B must also be When the vent ring B2 is set, when the adapter B is locked to the French vent 5, the stagnation ring B2 is brought into close contact with the shoulder 53 of the French ventilator.
  • the technical problem to be solved by the present invention is that in the prior art, when the general air nozzle is to inflate the French air nozzle, it must be matched with the adapter to complete the inflation, and thus it is troublesome in operation and use.
  • a primary object of the present invention is to provide a pneumatic nozzle for a French air nozzle which is provided with a compact structure by means of a small number of components to provide a French air nozzle for providing inflation.
  • the technical means of the present invention is to provide a special nozzle for a gas nozzle, comprising: a casing having a first end provided with an inflation hole, and an opposite second end provided with the inflation hole, and the nozzle is provided The inner space in which it is placed;
  • a nozzle plug having a first end having an enlarged diameter and being insertable into a space inside the outer casing, the end of the head being provided with a chamber for the nozzle plug to be inserted, and the second end has a a gas transmission hole communicating with the chamber;
  • a cap is assembled to the second end of the outer casing to prevent the nozzle plug from disengaging the outer casing.
  • the inner diameter of the inflation hole of the outer casing is provided with a first internal thread, and the second end of the outer casing is provided with a second inner thread, and the cap is provided with an external thread for screwing with the second internal thread.

  • the structure of the French air nozzle is thus provided to be dedicated to inflating the French air nozzle.
  • the nozzle plug is provided by a machining or integral molding technique, and one end portion is provided with an enlarged diameter head seat, and the head seat has a chamber for accommodating the nozzle plug, so that the side wall of the head seat is gas
  • the isolation function is provided between the nozzle plug and the inner diameter of the outer casing, thereby preventing the rubber nozzle and the metal material's outer casing from contacting each other and affecting the rotation function of the outer casing.
  • the through hole of the nozzle plug is linearly corresponding to the air inlet hole of the nozzle plug seat, and the through hole is available for the French nozzle
  • the pressure of the gas automatically pushes up the needle valve of the French nozzle, so that the air is filled into the inflated object.
  • the end edge of the through hole of the nozzle plug forms an inner edge corresponding to the shape of the shoulder of the French air nozzle, so that the French air nozzle is screwed to the inflation nozzle, the inner edge is adhered to the shoulder to prevent Air leaks.
