There is through hole inside the table top that projected square part indent rises, the base of described hydraulic jack has the through hole coordinated with the through hole,
The very useful bolt of described hydraulic jack is arranged in the projected square part of lower seated by through hole, and described upper connecting socket is installed described
In piston in hydraulic jack, described upper connecting socket is made up of two annulars, and described one end annular section is enclosed within support arm
The upper other end is arranged on the piston, and described fixing device is made up of annular section and projected square part, the annular section
It is installed above with upper connecting socket on piston, described fixing device projected square part is connected by screw on furnace upper cover, described
Big nut described piston is installed topmost.
Further, the little annular section of described upper connecting socket has one section into 50 degree of a concave station, and described upper connecting socket can be with
Move up and down on support arm.
Further, the piston of described hydraulic jack is made up of two sections of cylinders of size, and the top of small column carries
Screw thread, described hydraulic jack is also equipped with the handle supporting with crank.
Further, described fixing device annular section lower surface mid portion has a rectangular boss.
Further, there is an annulus of protrusion the centre of described support arm, described annulus it is uniform 4 it is threaded heavy
There is the boss with four screwed holes of protrusion hole, described furnace upper cover side.

Specific embodiment
In order to be better understood by technical scheme, vacuum sintering furnace of the present invention is risen with reference to Figure of description
Lid arrangement is further illustrated.
A kind of vacuum sintering furnace plays lid arrangement by lower seated 1, hydraulic jack 2, upper connecting socket 3, fixing device 4, big nut 5
Five parts constitute.Lower seated 1 is made up of annular section and projected square part, and on the annular section of lower seated 1 screwed hole is distributed, and is supported
There are the annulus of protrusion and uniform 4 threaded counterbores in the centre of arm 9, and the lower annular section of seated 1 is arranged on by screwed hole
On the support arm 9 of body of heater, it is ensured that lower seated is fixedly mounted on motionless on support arm 9, the table top that the projected square part indent of lower seated 1 rises
There is through hole inside.The base 8 of hydraulic jack 2 has the through hole as the lower projected square part of seated 1, with bolt hydraulic jack
2 and lower seated 1 coupled together by both middle through hole, upper connecting socket 3 is arranged in hydraulic jack in 2 piston 6, upper connecting socket
3 are made up of two annular sections, and wherein one end annular section is enclosed within support arm 9, and the other end is arranged on the work of hydraulic jack 2
On plug 6, the little annular section of upper connecting socket 3 has one section into 50 degree of a concave station, the movement that upper connecting socket 3 can be on support arm 9 back and forth,
Fixing device 4 is made up of annular section and square two parts, and annular section and upper connecting socket 3 are installed along with piston 6, on body of heater
There is the boss with four screwed holes of protrusion the side of lid 10, and the projected square part of fixing device 4 is arranged on furnace upper cover by screw
Above 10, while the annular section lower surface mid portion of fixing device 4 has a rectangular boss.The piston 6 of hydraulic jack 2
It is made up of two sections of cylinders of size, the top of small column is threaded, big nut 5 above small column by being threadably mounted at work
