Sealing structure capable of adjusting sealing degree

Abstract

The invention discloses a sealing structure capable of adjusting the sealing degree. The sealing structure comprises an accommodating box, wherein a fixed plate is arranged on the upper side of the accommodating box; a conical sealing plug is fixedly connected with the lower side of the fixed plate; a sealing opening corresponding to the conical sealing plug is formed in the top of the accommodating box; a mounting cover is fixedly connected with the bottom of the accommodating box; and two symmetrical transmission shafts are connected into the mounting cover through a transmission mechanism.According to the sealing structure, through cooperation of the transmission mechanism and a lifting mechanism, the conical sealing plug is driven to move downwards so as to adjust the sealing degree of the sealing opening, so that the conical sealing plug and the sealing opening fit closer; through cooperation of an outer gear ring, a support plate, a first spring, a limiting plate and liming teeth, the position of the conical sealing plug is not changed, so that the conical sealing plug does not move due to change of air pressure to enable the sealing degree of the conical sealing plug to behigher.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing structure with adjustable sealing degree. Background technique [0002] Sealing is a component or measure to prevent fluid or solid particles from leaking from adjacent joint surfaces and to prevent the intrusion of external impurities such as dust and moisture. At present, when sealing liquids, the sealing port is sealed by using a sealing plug. However, due to the air pressure in the containing box, the sealing plug will move up, so that the sealing degree is not good enough, and the contact of the sealing plug with the liquid will cause the loss of the sealing plug, so that the sealing effect is not good enough. Contents of the invention [0003] The purpose of the present invention is to solve the problem in the prior art that the air pressure in the storage box will cause the sealing plug to move up, so that the degree of sealing is not good enough, and the conta...
