Abstract
The invention provides a fast and efficient sealing structure which comprises a sealing cover and an installation hole in an electrical cavity in a casting box body. The sealing cover is installed on the installation hole. The sealing cover comprises an upper sealing cover body and a lower sealing cover body. A connecting rod is arranged in the middle of the lower sealing cover body. A through hole opposite to the connecting rod is formed in the upper sealing cover body. The connecting rod stretches into the through hole and penetrates out of the upper sealing cover body. The size of the upper sealing cover body is larger than that of the installation hole. The size of the lower sealing cover body is equal to that of the installation hole. The fast and efficient sealing structure has the advantages of being reliable in sealing, convenient to assemble and disassemble, simple in structure and high in working efficiency, and being fixed to the to-be-measured casing box body by means of the difference of pressures inside and outside the box body electrical cavity without bolts.
Description
Technical field
The present invention relates to one rapidly and efficiently sealing configuration.
Background technique
In Shell-Class mo(u)lded piece is produced, need to carry out certain pressure test to foundry goods, tested the quality judging foundry goods under normal circumstances by water pressure resistance; Water pressure resistance experimental setup in the past, sealing cover is fixed by screw with the mounting hole of Shell-Class foundry goods to be detected usually, when mounting and dismounting, wastes time and energy, and operating process is complicated.
Summary of the invention
The problem to be solved in the present invention is to provide one rapidly and efficiently sealing configuration.
For solving the problems of the technologies described above, the technical solution used in the present invention is: one is sealing configuration rapidly and efficiently, it is for the test of Shell-Class foundry goods water pressure resistance, and this structure comprises mounting hole (hereinafter referred to as mounting hole) and the sealing cover in electrically chamber in foundry goods casing, and sealing cover is arranged on described mounting hole;
Sealing lid comprises top cover labyrinth, lower sealing cover, connecting rod is provided with in the middle part of lower sealing cover, top cover labyrinth has the through hole relative with connecting rod position, connecting rod to stretch in through hole and wears out top cover labyrinth, described top cover labyrinth size is greater than mounting hole size, and lower sealing cover size is equal with mounting hole size.
Described top cover labyrinth is provided with decenter clutch, and this decenter clutch is made up of eccentric wheel and handle, eccentric wheel and connecting rod hinged, the length difference of described eccentric wheel major semi axis, semi-minor axis is equal with the width that top cover labyrinth, lower sealing cover form gap.
Described top cover labyrinth and the joint of lower sealing cover form a circular groove, establish a seal ring in circular groove.
Described lower sealing cover and connecting rod are integrally formed.
Described lower sealing cover is threaded with connecting rod.
The advantage that the present invention has and good effect are: the invention provides one rapidly and efficiently sealing configuration, it possesses following advantage:
(1) sealing is reliable, easy installation and removal;
(2) without the need to being screwed on foundry goods casing to be measured when installing, ensure that it maintains static by the pressure difference inside and outside the electric chamber of casing;
(3) structure is simple, working efficiency is high.

Embodiment
Embodiment:
As shown in Figure 1, 2: one is sealing configuration rapidly and efficiently, it is for the test of Shell-Class foundry goods water pressure resistance, and this structure comprises mounting hole 6 and the sealing cover in electrically chamber in foundry goods casing;
Sealing lid comprises top cover labyrinth 3, lower sealing cover 5, connecting rod 2 is provided with in the middle part of lower sealing cover 5, top cover labyrinth 3 has the through hole relative with connecting rod 2 position, connecting rod 2 to stretch in through hole and wears out top cover labyrinth 3, described top cover labyrinth 3 size is greater than mounting hole 6 size, lower sealing cover 5 size is equal with mounting hole 6 size, and top cover labyrinth 3 forms a circular groove with the joint of lower sealing cover 5, establishes a seal ring 4 in circular groove.
This top cover labyrinth 3 is provided with decenter clutch 1, and this decenter clutch is made up of eccentric wheel 101 and handle 102, eccentric wheel and connecting rod 2 hinged, the length difference of described eccentric wheel major semi axis, semi-minor axis is equal with the width that top cover labyrinth, lower sealing cover form gap.
Working principle: during installation, first top cover labyrinth 3 is connected with lower sealing cover 5, a circular groove is formed in its joint, seal ring 4 is put into groove, then this structure is loaded mounting hole 6, now seal ring 4 and top cover labyrinth 3, lower sealing cover 5 do not form intact seal action, and each parts are all in loosening state (now decenter clutch is in Fig. 1 position).When decenter clutch 1 is pulled to Fig. 2 position, due to the wobbler action of decenter clutch 1, lower sealing cover 5 followed by and promoted, and then cause the width of circular groove to diminish, seal ring 4 be squeezed be compressed to whole circular groove space in, now reach quick-sealing effect completely, because electric chamber pressure outside is greater than electric cavity pressure in process of the test, therefore sealing cover is fixed on mounting hole firmly, after off-test, treat that pressure is steady, decenter clutch 1 is turned back to Fig. 1 position, total can be taken off.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
