Abstract
The utility model provides a rapid and efficient sealing structure. The rapid and efficient sealing structure comprises an installing hole of the electrical chamber and a sealing cover, wherein the electrical chamber is formed in a casting box; the sealing cover is arranged on the installing hole and comprises an upper sealing cover and a lower sealing cover; the middle of the lower sealing cover is provided with a connecting rod; the upper sealing cover is provided with a through hole which is opposite to the connecting rod; the connecting rod extends into the through hole and penetrates out of the upper sealing cover; the size of the upper sealing cover is larger than that of the installing hole; the size of the lower sealing cover is equal to that of the installing hole. According to the rapid and efficient sealing structure, the sealing is reliable and the installation and detachment is convenient; during installation, the rapid and efficient sealing structure does not need to be fixed on the box of a casting to be tested through screws and can be fixed through the differential pressure inside and outside the electrical chamber of the box; the structure is simple and the working efficiency is high.
Description
Technical field
The utility model relates to a kind of 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, generally by water pressure resistance, test to judge the quality of foundry goods; 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 conventionally, when installation and removal, wastes time and energy, and operating process is complicated.
Model utility content
Problem to be solved in the utility model is to provide a kind of rapidly and efficiently sealing configuration.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rapidly and efficiently sealing configuration, it is tested for Shell-Class foundry goods water pressure resistance, this structure comprises mounting hole (hereinafter to be referred as mounting hole) and the sealing cover in electric chamber in foundry goods casing, and sealing cover is arranged on described mounting hole;
Sealing lid comprises top cover labyrinth, lower sealing cover, lower sealing cover middle part is provided with connecting rod, top cover labyrinth has the through hole relative with connecting rod position, connecting rod stretches 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 equates with mounting hole size.
Described top cover labyrinth is provided with decenter clutch, and this decenter clutch is comprised of eccentric wheel and handle, and eccentric wheel and connecting rod are hinged, and the length difference of described eccentric wheel major semi axis, semi-minor axis equates 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.
Advantage and the good effect that the utlity model has are: the utility model provides a kind of rapidly and efficiently sealing configuration, and it possesses following advantage:
(1) sealing is reliable, easy installation and removal;
(2) while installing, without being screwed on foundry goods casing to be measured, by the pressure difference inside and outside the electric chamber of casing, guarantee that it maintains static;
(3) simple in structure, working efficiency is high.

Embodiment
Embodiment:
As shown in Figure 1, 2: a kind of rapidly and efficiently sealing configuration, 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 electric chamber in foundry goods casing;
Sealing lid comprises top cover labyrinth 3, lower sealing cover 5, lower sealing cover 5 middle parts are provided with connecting rod 2, top cover labyrinth 3 has the through hole relative with connecting rod 2 positions, connecting rod 2 stretches in through hole and wears out top cover labyrinth 3, described top cover labyrinth 3 sizes are greater than mounting hole 6 sizes, lower sealing cover 5 sizes equate with mounting hole 6 sizes, 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 comprised of eccentric wheel 101 and handle 102, and eccentric wheel and connecting rod 2 are hinged, and the length difference of described eccentric wheel major semi axis, semi-minor axis equates 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, in its joint, form a circular groove, seal ring 4 is put into groove, then pack this structure into mounting hole 6, now seal ring 4 does not form intact seal action with top cover labyrinth 3, lower sealing cover 5, 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, wobbler action due to decenter clutch 1, lower sealing cover 5 is being followed and is being raised, and then cause the width of circular groove to diminish, seal ring 4 is squeezed and is compressed in the space of whole circular groove, now reach quick-sealing effect completely, in process of the test because electric chamber pressure outside is greater than electric cavity pressure, 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 embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
