Description

technical field

[0001] The invention relates to the technical field of train accessories, in particular to an air inlet protective plug for a train brake rear cover and a preparation method thereof. Background technique

[0002] There is an air inlet on the rear cover of the train brake. Because the corresponding train accessories are easy to collide with each other during transportation, the paint on the air inlet connector will be peeled off or worn, which will affect the service life of the accessories. At the same time, if the air inlet is not protected, it will cause damage. Dust, liquid, etc. enter the air inlet, affecting the normal operation of the equipment. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, and provide a protective plug for the air inlet of the train brake rear cover and a preparation method thereof.

[0004] In order to solve the above technical proble...
