Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] Such as Figure 1-6 The ejection device shown includes a tubular housing with a three-way structure, such as figure 1 , the left end is the damper end that communicates with the outside atmosphere, the right end is the air outlet end that communicates with the air bag, the upper end is the intake end that connects the high-pressure gas, the intake end is connected with an intake valve, and the valve body 11 lower part of the intake valve is inserted into the shell, The upper internal thread is screwed with an air inlet nozzle 3, and a first sealing ring 15 is provided between the air inlet nozzle 3 and the valve body 11. There is a pipeline for communicating with the inner cavity of the housing in the valve body 11. There is a one-way valve in the pipeline so that the gas can only flow in one direction from the pipeline inlet to the gas outlet. The o...

Abstract

The invention relates to an injection device for a life-saving air bag, comprising a three-way shell, one end of the shell is an intake end for communicating with a high-pressure gas intake while the other end of which is an outtake end for communicating with the air bag and the final end of which is an air door end for communicating with outside atmosphere, the three ends are intercommunicated, an end cover is arranged on the air door end, an air door hole is formed on the end cover, an air door pressing plate capable of opening and closing the air door hole through elastic deformation under air pressure at two sides of the air door hole is fixed at an inner side of the end cover, and the air door pressing plate comprises a fixed part which is fixed on the end cover, and an elastic bending part which covers and seals the air door hole. The device not only can be reused, but also has no chemical safety problems; air is inhaled under negative pressure which is generated while injecting high-pressure gas in the air bag, and the air door can be automatically closed in an air inflation process. The whole device is light in weight, reliable in sealing, large in injection ratio, automatic in pull-in after injection and very convenient in use and maintenance.

Description

technical field [0001] The invention relates to a special injection device for inflating a rescue air bag. Background technique [0002] Existing life-saving airbags and other life-saving equipment often use chemical methods to react two substances in a crisis situation, and a large amount of gas is instantly generated to fill the rescue airbag. Because this method is disposable, the cost itself is relatively high, and the reactants may have problems due to long-term storage, resulting in low safety and reliability. Contents of the invention [0003] The object of the present invention is to provide an injector for a life-saving airbag to solve the problems of high cost and low reliability of the existing airbag inflation method. [0004] In order to achieve the above object, the solution of the present invention is: an ejector device for rescue airbags, which includes a three-way housing, one end of the housing is used to communicate with the inlet end of the high-pressu...
