Air inflation tool and air inflation method for refrigerating machine

Abstract

The invention belongs to the technical field of refrigerators, and discloses a refrigerator inflation tool which comprises an inflation cylinder body, an inflation shaft and an adjusting mechanism. The two ends of the inflation shaft penetrate through the inflation cylinder body and extend out of a top opening and a bottom opening of the inflation cylinder body respectively, the bottom opening of the inflation cylinder body is connected with an inflation connector of a refrigerating machine, an inflation pipe of the inflation cylinder body is connected with a high-pressure gas cylinder, and the bottom structure of the inflation shaft is matched with a blocking nail in the inflation connector. The adjusting mechanism comprises a rotary handle, a rotary fixing block, a bearing, a first anti-rotation switch and a second anti-rotation switch, and the first anti-rotation switch controls the rotary handle and the inflation shaft to rotate simultaneously or asynchronously; the second anti-rotation switch controls the rotary fixing block and the inflation cylinder body to rotate simultaneously or asynchronously. The inflation tool is only provided with one adjusting mechanism, the structure is simple, the weight is light, and operation is convenient and efficient in the using process.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to an inflatable tool for a refrigerator and an inflation method, and more particularly, to a single adjustment mechanism, an inflatable tool for a Stirling refrigerator with multiple adjustment functions, and an inflation method. Background technique [0002] As an important part of the detector, the rotating integral Stirling refrigerator (hereinafter referred to as "refrigerator") is mainly used to provide a stable ultra-low temperature working environment for the normal operation of the detector and improve the performance of the detector. After the refrigerator is coupled with the Dewar, in order to meet the normal operation of the refrigerator, it is necessary to fill the refrigerator body with high-pressure gas (such as helium) with a certain pressure, which requires a high-pressure gas cylinder and the refrigerator for gas transportation. of inflatable tooling (or fixt...

AI Technical Summary

Problems solved by technology

[0004] (1) When screwing the threaded joint of the inflatable tooling and the inflatable threaded joint of the refrigerator, by rotating the body of the refrigerator or the inflatable tooling body, because the inflatable tooling is a cylinder, and the side is generally equipped with a gas pipe, which is easy to touch. When it is tight, it is easy to cause the trachea of ​​the inflatable tool to be twisted;

[0005] (2) There are many adjustment mechanisms and rotating handles. During use, multiple adjustment mechanisms or operating rotating handles are required to be replaced, which makes the operation complicated, and also increases the structural composition and weight of the inflatable fixture;

[0006] (3) Part of the inflatable tooling does not have an adjustment mechanism, and it is pressed purely by hand, which is time-consuming and laborious
