Description

Wind mouth and its mouth

The invention relates to the technical field of a pneumatically tightened American or French to be inflated nozzle for a nozzle of a tuyere.

Press, the previous wind mouth will be like China's application No. 095107665, No. 097203517. . As shown in the previous patent case, the patents are mainly forcing the axial deformation of the nozzle through the downward movement of the cylinder to "indirectly" actuate the radial deformation of the nozzle. Inflatable nozzle, the radial deformation of the nozzle is quite limited, so the force of the nozzle to be inflated is quite limited, so when inflating, it is very easy to have the disadvantage of air leakage or looseness.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

The invention provides a tuyere head and a mouthpiece thereof, which mainly makes the mouthpiece have a pneumatic tight-fitting American or French-style inflatable nozzle design, so that the nozzle bundle can be more stable and stable.

In order to meet the above technical requirements, the nozzle of the present invention has at least: a sleeve hole recessed by the inner end, the sleeve hole is provided for airtightly engaging the valve plug inside the wind nozzle; a mouth hole penetrating the inner end and the outer end, the aperture hole of the mouth hole is arranged to be small and large inside, so that it can provide an American or French to be inserted into the inflation nozzle, and the nozzle hole is coaxial with the sleeve hole. , but the diameter of the mouth hole is smaller than the diameter of the sleeve hole; and a pressure accumulation chamber recessed along the outer end direction of the sleeve hole, the pressure accumulation chamber is annularly symmetric and concentrically arranged outside the mouth hole, so as to facilitate An annular and flexible forced wall is defined between the pressure accumulating chamber and the nozzle hole, and the end of the pressure accumulating chamber is connected to communicate with the valve plug, so that the valve plug is inflated in the American or French air inlet nozzle in the mouth hole At the same time, the accumulator chamber can be simultaneously inflated, so that the accumulator chamber can be used as the diameter of the wall of the retracting wall to further maintain the mouth hole to conceal the American or French to be inflated nozzle, so that the air leaking when inflating can be performed. The situation is minimized and there is no need to loosen the aeration nozzle.

From the above description, the present invention has at least the following advancement:

1. The invention only needs to manipulate the gymnastics to be inserted into any nozzle through one hand, that is, the valve plug can be pushed to the fixed point by the direction, so that the valve hole can actuate the corresponding jaw and the mouth for automatic use. The one-hand operation mode is far more convenient than the conventional two-hand operation.

2. The nozzle of the present invention is through the coaxial interlocking relationship between the valve hole and the clamping jaw, so that it can "directly and fully" radially deform the strong force to clamp the to-be-inflated nozzle, and pneumatically press or maintain the opposite connection through the accumulator chamber. The radial deformation of the mouth, the double bundle structure relationship, can minimize the air leakage during air pumping, and does not require the possibility of looseness of the air nozzle.

Third, the overall structure of the present invention is far more streamlined than conventional.

Please refer to the tenth, eleventh and twelfth drawings, which further illustrate that the mouthpiece of the present invention can be implemented in a single air nozzle, and the first nozzles 40 shown in the tenth and eleventh figures are individually implemented in the wind mouth. In this case, the wind mouth can only provide the second specification of the second to-be-inflated nozzle 80. The same reason, when the second nozzle 30 shown in the twelfth is implemented in the wind nozzle, the tuyer head can only provide The American standard first to be inflated nozzle 70 is used.

It is known from the above description that the overall structural configuration of the present invention is novel, and the leakage of the air can be minimized, and the possibility that the inflation nozzle is loose is not required, which is a high-invention in the technical concept, and should be patented. Apply for the requirements and apply in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention should still be covered by the present invention.
