Description

法式气嘴专用的充气嘴 技术领域  Inflatable nozzle for French air nozzle
本发明涉及一种充气嘴， 尤其涉及一种用来专门对法式气嘴进行充气的 充气嘴。 背景技术  The present invention relates to an aeration nozzle, and more particularly to an inflation nozzle for specifically inflating a French air nozzle. Background technique
气嘴普遍被设置在诸如车辆轮胎等被充气物； 当需要充气时， 将设在输 气管的充气嘴或打气筒的充气嘴连接于该气嘴， 便能操作打气筒将气体打入 被充气物内。  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. Inside.
现有技术中的气嘴进气口均设有气阀顶针； 当气阀顶针不受到外力作用 时， 被充气物内部的气压会促使气阀处于密闭状态， 以避免气体外泄； 当外 物对该气阀顶针施加作用力时， 则会开启该气阀， 从而使被充气物的内部与 外界相通， 使气体能够排出被充气物外， 或是将气体充入被充气物内。  In the prior art, 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.
另外， 气嘴的规格很多， 其中的法式气嘴具有不同于一般气嘴的结构。 如图 6所示， 所述法式气嘴 5具有两段式螺纹 (包含较大外径的第一外螺纹 51， 以及较小外径且接近自由端的第二外螺紋 52， 第一外螺纹 51与第二外 螺纹 52之间形成有肩部 53。 由于目前市面上并没有专门配合该法式气嘴的 充气嘴， 因此欲对法式气嘴进行充气时， 必须在一般的充气嘴 A组合转接头 B， 再利用设于转接头 B的内螺纹 B 1锁合于法式气嘴 5的第二外螺纹 52(如 图 7所示)。 此外， 为了避免空气外泄， 该转接头 B 内径还必须设置止泄环 B2 , 使转接头 B锁合于法式气嘴 5时， 让止泄环 B2密合于法式气嘴的肩部 53 ο 发明内容  In addition, the specifications of the gas nozzle are many, and the French gas nozzle has a structure different from that of the general gas nozzle. As shown in FIG. 6, 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). In addition, in order to avoid air leakage, 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.
本发明所要解决的技术问题， 是现有技术中的一般充气嘴要对法式气嘴 进行充气时， 必须配合转接头才能完成充气， 因此在操作使用上较麻烦。  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.
本发明的主要目的在于提供一种法式气嘴专用的充气嘴， 其借助少量的 组件组成精简的结构， 便能提供法式气嘴专用而提供充气。 本发明的技术手段是提供的 种法式气嘴专用的充气嘴， 包括： 一外壳， 其第一端设有充气孔， 相对的第二端设有与该充气孔相通， 并 且提供该气嘴塞座置于其中的内空间； SUMMARY OF THE INVENTION 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;

再者， 当所述气嘴塞设于该气嘴塞座的腔室后， 恰好使气嘴塞的贯穿孔 与气嘴塞座的输气孔直线对应， 且该贯穿孔可供法式气嘴穿入， 当充入压缩 气体时，气体的压力自动将法式气嘴的针阀顶开，从而使空气充入被充气物。  Furthermore, when the nozzle plug is disposed in the chamber of the nozzle plug seat, 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 When it is filled in, when the compressed gas is charged, 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.
此外， 当所述气嘴塞的贯穿孔端缘形成对应该法式气嘴的肩部形状的内 缘，使得法式气嘴螺合于充气嘴时，让该内缘密贴于该肩部而防止空气泄露。  In addition, when 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.
本发明通过前述组件组成的充气嘴结构， 可以直接对法式气嘴进行充 气， 不需要如现有技术中的一般气嘴般必须配合转接头才能充气， 因而使用 更为方便。 附图说明  The inflating nozzle structure composed of the foregoing components can directly inflate the French air nozzle, and does not need to be matched with the adapter to inflate as in the conventional gas nozzle of the prior art, so that the use is more convenient.
