Abstract

The invention discloses a protecting device used for a pipe opening and belongs to the technical field of cooler parts. The invention aims at solving the technical problems that the sealing and protecting effects of water inlet and outlet pipes in the prior art are poor, and product inner cleanliness cannot be ensured. The invention adopts the technical scheme that the protecting device comprisesa dust cover, wherein the bottom end of the dust cover is provided with a plurality of fall-proof sealing ribs surrounding the inner wall of the dust cover, and a ventilation hole is formed in the central part of the top end surface of the dust cover. The device has great sealing and protecting effects and can ensure product inner cleanliness.

Description

technical field [0001] The invention relates to the technical field of radiator components, in particular to a protective device for nozzles. Background technique [0002] At present, automotive radiators, intercoolers and other products are equipped with water inlet and outlet pipes or air inlet and outlet pipes. In order to ensure the internal cleanliness during the product turnover process, no foreign matter, impurities, dust, etc. will enter the product cavity. There are plastic films or plastic dust-proof covers for sealing protection. [0003] For example, the patent 201621396781.1 is named "water chamber connection structure". The technical scheme adopted in this patent is: including the lower water chamber, the core body assembly, the upper water chamber, the water outlet pipe and the water inlet pipe. The inlet and outlet pipes are equipped with dust-proof covers. It has the functions of dustproof and sealing; there are many kinds of traditional dustproof covers, b...
