As an optimized technical scheme, a sealing groove is arranged on the inner side surface of the door inner plate, the sealing groove surrounds the edge of the door inner plate, the sealing groove is positioned on the inner side of the pressing frame, and an O-shaped sealing ring is arranged in the sealing groove.
As a preferable technical scheme, both sides of the door outer plate are provided with door side covers, a door fixing seat is fixed in the door side covers, and a connecting hole site is arranged on the door fixing seat.
The beneficial effects of the utility model are as follows: the vacuum floating door has the advantages that the distance between the inner plate and the outer plate of the door can be changed by using the spring, the door is changed from a hard contact door to a soft contact door, the vacuum tightness is enhanced, the door body is tightly closed, and the spring is used for buffering in the door closing process.
Drawings
The utility model is described in further detail below with reference to the drawings and examples.
FIG. 1 is a schematic view of the overall structure of a vacuum floating door according to an embodiment;
fig. 2 is an internal structural view of a vacuum floating door according to an embodiment.
In fig. 1 to 2:
1. a door outer panel; 2. a stiffener frame; 3. a door inner panel; 4. vacuum cavity position; 5. a spring; 6. pressing a frame; 7. a spring seat; 8. an O-shaped sealing ring; 9. a door side cover; 10. a door fixing seat; 11. and connecting the hole sites.
Detailed Description
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 2, in this embodiment, a vacuum floating door includes an outer door plate 1, a reinforcing rib frame 2 and an inner door plate 3, a vacuum cavity 4 is formed on the inner side of the outer door plate 1, the reinforcing rib frame 2 is located in the vacuum cavity 4, a spring 5 is disposed between the reinforcing rib frame 2 and the inner door plate 3, a pressing frame 6 is disposed on the edge of the vacuum cavity 4, the pressing frame 6 presses the inner side of the edge of the inner door plate 3, and the pressing frame 6 is fixedly connected with the edge of the outer door plate 1.
When the vacuum furnace needs to be sealed and closed, the door outer plate 1 moves to the front of the vacuum furnace, the reinforcing rib frame 2 and the door inner plate 3 are gradually close to the opening of the vacuum furnace under the driving of the door outer plate 1, the spring 5 in the vacuum cavity position 4 starts to act when the door inner plate 3 is pressed at the opening of the vacuum furnace, the pressure caused by direct collision is buffered, the pressing speed of the door inner plate 3 is slowed down under the condition that the final pressure is not influenced, and meanwhile, under the vacuum action of the vacuum cavity position 4, the heat loss in the vacuum furnace is reduced, and the normal baking temperature of the vacuum furnace is ensured.
Be fixed with a plurality of spring holders 7 on the strengthening rib frame 2, spring 5 installs at spring holder 7's middle part, in order to prevent that spring 5 from removing at will in strengthening rib frame 2, the welding has spring holder 7 on strengthening rib frame 2, is responsible for spacing spring 5's position, and the distribution is even, and door inner panel 3's resilience effect can not slope.
The inner side of the door inner plate 3 is provided with a sealing groove, the sealing groove surrounds the edge of the door inner plate 3, the sealing groove is positioned on the inner side of the pressing frame 6, an O-shaped sealing ring 8 is placed in the sealing groove, when the door inner plate 3 is pressed on the vacuum furnace, the O-shaped sealing ring 8 in the sealing groove is firstly contacted with the edge of the opening of the vacuum furnace to seal, and the sealing effect is ensured by deformation after stress extrusion.
Both sides of the door outer plate 1 are provided with door side covers 9, a door fixing seat 10 is fixed in the door side covers 9, a connecting hole site 11 is arranged on the door fixing seat 10, when the whole floating door is controlled to move up and down, the door fixing seat 10 is inserted from the connecting hole site 11 by means of an external supporting rod, the door side covers 9 on both sides of the door outer plate 1 are driven to draw, move up and down in the vertical direction and aim at the opening of the vacuum furnace to close the door.
It should be noted that the above embodiments are merely preferred embodiments of the present utility model and the applied technical principles, and any changes or substitutions easily conceivable to those skilled in the art within the scope of the present utility model are included in the scope of the present utility model.
