Abstract

The invention discloses a connecting nozzle capable of being widely applied to different types of inflation nozzles. Trepanning holes combined with a valve plug in an air nozzle head in an air tight mode are formed in the inner end of the connecting nozzle in a concaved mode. The connecting nozzle is provided with nozzle holes penetrating through the inner end and the outer end. The aperture of each nozzle hole is large in exterior but small in interior, and therefore a nozzle to be inflated can be inserted and positioned in the corresponding nozzle hole; the nozzle holes and the trepanning holes are coaxially formed, and the diameter of the nozzle holes is smaller than that of the trepanning holes. Pressure storage chambers are arranged in the connecting nozzle in the direction from the trepanning holes to the outer end in a concaved mode and are annularly, symmetrically and concentrically arranged outside the nozzle holes, an annular and flexible forced wall is defined between the pressure storage chambers and the nozzle holes, the inner ends of the pressure storage chambers can be controlled to be communicated with the valve plug so that when the valve plug inflates the American or France nozzle to be inflated in the nozzle holes, the pressure storage chambers can be synchronously inflated, the pressure storage chambers are forced to act on the forced wall, the diameter of the nozzle holes is reduced, the American or France nozzle to be inflated can be restrained through the nozzle holes, and it can be ensured that when the nozzle to be inflated through the nozzle holes, it is not possible that the nozzle to be inflated loosens and leaks air at will.

Description

technical field [0001] The invention relates to a tuyere head of an inflatable device, in particular to a tuyere head with an aerodynamically tightened American or French style to-be-inflated nozzle and its joint. Background technique [0002] Existing tuyere heads are just as shown in patents such as No. 095107665 and No. 097203517 in Taiwan, China. However, these prior patents mainly force the axial deformation of the joint through the downward movement of the pressure cylinder, so as to "Indirectly" activates the radial deformation of the clamping nozzle of the American or French type to be inflated. There are disadvantages of air leakage or looseness. [0003] In view of this, the inventor of the present invention aimed at the many defects and inconveniences caused by the imperfect structural design of the above-mentioned tuyere head and joint, and conceived deeply, and actively researched and improved the trial production to develop and design this case.
