Description

Sealing cover body and oil barrel Technical Field The utility model belongs to the technical field of plastic barrels, and particularly relates to a sealing cover body and an oil barrel. Background In the prior art, oil barrels are widely used in industry, agriculture, and daily life for storing and transporting various kinds of oil. However, the traditional oil barrel has poor sealing performance, is easy to leak oil, is easily influenced by external environment particularly in the transportation process, causes oil leakage, and causes resource waste and environmental pollution. Therefore, how to improve the sealing performance of the oil barrel is a problem to be solved. Disclosure of utility model In order to overcome the defects in the prior art, the utility model aims to provide a sealing cover body and an oil charging bucket, which are mainly used for solving the defects of poor sealing performance and the like of the traditional oil charging bucket. In order to solve the problems, the technical scheme adopted by the utility model is as follows: in a first aspect, the present utility model provides a sealing cap for sealing a tub, comprising: The bottom of the cover body is provided with an assembly groove, an inner seal is embedded in the assembly groove, a first sealing boss positioned at the bottom of the groove, a second sealing boss positioned at the wall of the groove and a third sealing boss are arranged at the groove of the inner seal, the first sealing boss is used for being abutted with the top wall of the matching part at the top end of the barrel body, and the second sealing boss and the third sealing boss are respectively used for being abutted with the side wall of the matching part at the top end of the barrel body; The cover body comprises an outer edge back-off part, and the outer edge back-off part is used for limiting connection with the buckling position of the matching part. In some embodiments, the mating clearance between the first sealing boss and the outer rim undercut is less than the distance between the mating portion top wall and the undercut. In some embodiments, the mating surfaces of the second and third sealing bosses are beveled and are interference fit with the mating portion. In some embodiments, the inner seal is made of polyethylene material. In some embodiments, the top surface of the cover body is further provided with an oil outlet member, and the oil outlet member comprises an inner cover and an outer cover; the inner cover is fixed on the abdication hole on the top surface of the cover body, and is provided with a tearing opening; The outer cover comprises a fixing part and a protecting part, wherein the fixing part is connected to the top of the inner cover, and the protecting part is connected with the fixing part through a plurality of bridge points.
