Abstract
The invention relates to a sealing structure for a sealing box, comprising a concave sealing groove, a sealing rubber ring and a strip-stake shaped convex boss. The periphery of the strip-stake shaped convex boss and the periphery of the concave sealing groove are sealed; the strip-stake shaped convex boss is arranged on the top of the box of the electrical sealing box; the concave sealing groove is arranged on the cover of the electrical sealing box; and the concave sealing groove is matched with the sealing rubber ring. When the electrical sealing box is covered by the cover, the strip-stake shaped convex boss is rightly arranged in the concave sealing groove. The strip-stake shaped convex boss is matched with the concave sealing groove and the sealing rubber ring, thus the problems that the sealing rubber ring of the prior electrical sealing box can be easily damaged by the outside corrosive medium and the protection level of the electrical sealing box is hereby reduced are solved.
Description
Technical field
The present invention relates to a kind of hermetically-sealed construction, relate generally to a kind of hermetically-sealed construction that is used for electric sealed box.
Background technology
Along with the development of the modernization of industry and the progress of science and technology; domestic manufacturing industry; the various great complete automatic control equipment of industries such as the Important Project project of especially many countries such as subway, harbour, power station, shipbuilding, petrochemical industry and mine metallurgy need badly a large amount of have high-protection level, shock proof, corrosion resistant and fire-retardant nontoxic electric sealed box comes various electrical and electronic parts and control device in the protection equipment, can safe and reliable work in various rugged environments and weather to guarantee equipment.Generally adopt macromolecular materials such as Merlon, polyester, ABS to make the electric sealed box of high-protection level by the technology of injection mo(u)lding at present at western developed country, at home, electric sealed box adopts O-ring seal to seal in the design of hermetically-sealed construction, the shortcoming of this design is: O-ring seal is subjected to erosion, the corruption of external environment easily, in case O-ring seal is aging, the sealing effectiveness of electric sealed box reduces greatly.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of hermetically-sealed construction of electric sealed box, makes the degree of protection of electric sealed box reach IP67.
For solving the problems of the technologies described above, the hermetically-sealed construction of stuffing box of the present invention includes spill seal groove, O-ring seal and strip short wooden stake shape boss.Sealing around strip short wooden stake shape boss and the spill seal groove, strip short wooden stake shape boss is arranged on the top of electric sealed box casing, and the spill seal groove is arranged on the electric sealed box case lid, and the spill seal groove is equipped with O-ring seal, when case lid closed, strip short wooden stake shape boss just in time placed in the spill seal groove.
The hermetically-sealed construction of stuffing box of the present invention, strip short wooden stake shape boss cooperates the design of spill seal groove and O-ring seal to solve in the past well, and the O-ring seal of electric sealed box is destroyed the problem that causes the electric sealed box degree of protection to reduce easily by the Korrosionsmedium in the external world.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Symbol description among the figure:
Electric sealed box case lid 1, spill seal groove 2, O-ring seal 3, electric sealed box casing 4, strip short wooden stake shape boss 5.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in drawings, spill seal groove 2, O-ring seal 3 and strip short wooden stake shape boss 5 have been the present invention includes.Sealing around strip short wooden stake shape boss 5 and the spill seal groove 2, strip short wooden stake shape boss 5 is arranged on the napex of electric sealed box casing 4, spill seal groove 2 is arranged on the electric sealed box case lid 1, spill seal groove 2 is equipped with O-ring seal 3, when case lid 1 closed, strip short wooden stake shape boss 5 just in time placed in the spill seal groove 2.The hermetically-sealed construction of stuffing box of the present invention, strip short wooden stake shape boss 5 cooperates the design of spill seal groove 2 and O-ring seal 3 to solve in the past well, and the O-ring seal 3 of electric sealed box is destroyed the problem that causes the electric sealed box degree of protection to reduce easily by the Korrosionsmedium in the external world.
