Description

Technical Field

[0001] This utility model relates to the field of aircraft pipe fittings, and in particular to a complete set of dustproof and sealing aircraft plugs. Background Technology

[0002] When an aircraft is in a state of engine malfunction in the field, various oil lines and pipe joints on the aircraft and engine are exposed to the air, making them highly susceptible to contamination. Currently, in the field, when the engine is in a state of engine malfunction, the common practice is to use simple plastic bags to cover the pipe joints and tighten them with rubber bands to ensure dust and contamination prevention. However, this method of contamination prevention is crude and has the following problems:

[0003] 1. Poor dustproof effect: the plastic bag itself may be covered with dust, and it cannot guarantee a sealing effect on oil pipe joints at all;

[0004] Second, there is no clear requirement for whether plastic bags should be reused or replaced after use, and the same plastic bag is used in various pipe interfaces in a cross manner.

[0005] Third, the aesthetics are poor, and the simple bagging method is arbitrary, which affects the overall appearance. Utility Model Content

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] As attached Figures 1-2 The dustproof sealing aircraft complete set of plugs shown includes a handle 1, a housing 2, EVA foam 3, a plug, a nut 7, EVA foam gaps 8, a plug name label 9, and a mold 10.

[0025] The handle 1 is located on the lower part of the box body 2, the plug is embedded in the EVA foam 3, the nut 7 is located in the middle of the plug, the EVA foam gap 8 contacts the box body 2, the plug name label 9 is located on the plug, and the engraving 10 is located below each plug and corresponds to the plug name label 9.

[0026] Furthermore, a complete set of dustproof sealing caps for aircraft, the caps including small caps 4, medium caps 5, large caps 6, and extra-large caps 11;

[0027] The small plug 4, medium plug 5, and large plug 6 are installed on the first layer of the box 2;

[0028] The extra-large plug 11 is installed on the second layer of the box body 2.

[0029] Furthermore, a complete set of dustproof sealing caps for aircraft, wherein the small cap 4 is smaller in volume than the medium cap 5, smaller than the large cap 6, and smaller than the extra-large cap 11.

[0030] Furthermore, a dustproof and sealing aircraft complete set of plugs, wherein the engraving 10 is disposed on EVA foam 3.

[0031] Furthermore, a complete set of dustproof and sealing aircraft covers, wherein the dimensions of the housing 2 are 479×333×127mm or 380×280×90mm.

[0032] Furthermore, a dustproof and sealing aircraft complete set of plugs, wherein the housing 2 comprises two layers of EVA foam 3.

[0033] Furthermore, a complete set of dustproof sealing caps for aircraft, wherein the small cap 4, medium cap 5, and large cap 6 are arranged in order of volume from top to bottom.

[0034] A complete set of dustproof and sealing caps for aircraft is implemented by using a handle 1 to make the box 2 portable. The caps are customized in size according to the type of aircraft, engine, accessory housing, and corresponding pipe joints. The caps are placed in the box according to their size, ensuring the feasibility of sealing each pipe joint after the aircraft is damaged. Each cap has a name label 9 on the top and a mold 10 in the EVA foam 3 below that corresponds to the name label 9. If a cap is found to be missing in a certain layer of the box, it can be checked whether the cap was left on the product, preventing human error.
