Automobile water storage bottle pressure cover with good sealing performance

Abstract

The invention provides an automobile water storage bottle pressure cover with good sealing performance, and belongs to the technical field of automobile accessories. The problem that an existing water bottle pressure cover is poor in sealing performance is solved. The pressure cover sealing structure of the automobile water storage bottle comprises a cover body, a hollow cavity is formed in the cover body, and an upper opening and a lower opening which are communicated with the interior of the cavity are formed in the upper end and the lower end of the cover body respectively. A first sealing assembly and a second sealing assembly which are matched with each other, used for sealing the upper opening and the lower opening and capable of moving up and down are arranged in the cavity, an adjusting compensation plate is arranged between the first sealing assembly and the second sealing assembly, and the upper end of the adjusting compensation plate abuts against the first sealing assembly. The lower end of the adjusting compensation plate is in movable contact with the second sealing assembly, and the outer surface of the upper end of the cover body is sleeved with a sealing ring. The sealing structure has the advantage of being good in sealing performance.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a pressure cap for an automobile water storage bottle with good sealing performance. Background technique [0002] The pressure cap used in the car water storage bottle plays a vital role in the cooling system, and in order to ensure that the pressure cap can better seal and relieve pressure, the requirements for the sealing spring structure are particularly important. All of the pressure caps of the company are springs acting on the sealing structure, but because the springs are twisted during use and cannot meet the entire flatness requirements, etc., the pressure caps will leak in advance, resulting in lower product qualification rates. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above problems, and to provide a sealing structure for the pressure cap of an automobile water bottle with good sealing performance. [0004] To achieve ...
