Problems solved by technology

[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

Abstract

The invention discloses a protective plug of an air inlet of a train brake rear cover. The protective plug comprises a protective sleeve arranged on a connector of the air inlet in a sleeving mode andan air inlet threaded plug matched with an internal thread of the air inlet, an open groove matched with the connector of the air inlet in shape is formed in the protective sleeve, wherein the air inlet threaded plug comprises a threaded rod and a plugging stopper arranged at the end portion of the threaded rod, and the diameter of the plugging stopper is larger than that of the air inlet. The invention further discloses a preparation method of the protective plug of the air inlet of the train brake rear cover. According to the protective plug of the air inlet of the train brake rear cover and the preparation method thereof, the connector of the air inlet is protected through the protective sleeve, the air inlet is closed through the air inlet threaded plug, so that dust, a liquid and thelike are prevented from entering the air inlet, and the prepared protective plug of the air inlet is quite high in wear resistance.

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...
