Description

[Detailed Description of the Invention] The present invention relates to an improvement of an autoclave door hinge.

As shown in FIG. 1, the conventional autoclave door hinge has a hinge shaft 3, which is separate from the hinge 2, inserted into the hollow part of the hinge 2, which is integrated with the autoclave door 1, and is hinged by a collar 4 and a pin 5. A hinge shaft 3 is connected to the autoclave body 2, and a bearing 7 is connected to a bearing 6 with both ends of the hinge shaft 3 fixed to the autoclave body.
Adjustment bolt 8 fitted through the bearing 6 and provided on the bearing 6
The vertical position of the hinge shaft 3 can be adjusted, and the left-right and front-back positions of the hinge 2 and the hinge shaft 3 can be adjusted using adjustment bolts 9 provided on the hinge 2.

Therefore, the structure is complicated and it takes time to assemble, and the adjustment is difficult because the gap between the hinge shaft 3 and the hinge 2 is small and the mounting angle of the adjustment bolts 8 and 9 is not appropriate. It was hot.

The purpose of the present invention is to eliminate such drawbacks and provide an autoclave door hinge that is simple in structure and easy to adjust.The main points of this invention are as follows:
A hinge shaft integrated with the door is loosely fitted into a bearing box fixed to the autoclave body, and the hinge shaft can be adjusted freely using an adjustment bolt provided in the bearing box. This will be explained with reference to FIG.

A hinge shaft 12 is integrally formed at both ends of the hinge 11 of the autoclave door 10, and a bearing 1
The stopper 17 is fitted into the housing 14 via a stopper 17, which is sealed by an oil seal 16 housed in an oil case 15.
is engaged with the groove 12a of the hinge shaft 12, the stopper 17 is fixed to the housing 14 with the oil case 15 in between by a bolt 18, and the hinge shaft 12 is rotatably supported by the housing 14.

The bearing box 19, which is provided integrally with the autoclave main body, has a box shape with a front wall plate 19a that can be attached and detached with bolts 20, and the housing 14 is loosely fitted inside the box with a predetermined gap. Adjustment bolts 21 and 22 are provided on the outer circumferential wall of the autoclave, so that the hinge shaft 12, that is, the autoclave door 10, can be directly adjusted freely in the up, down, right, left, and back directions.

Also, when assembling, the front wall 19a of the bearing box 19
Since it has a structure that can be attached and detached using bolts 20, by removing these bolts, the hinge 11 can be attached and detached from the bearing box 19 with the housing 14 still attached.

As described above, in the present invention, the hinge shaft is integrally formed with the hinge, and the housing that rotatably supports the hinge shaft is provided in the bearing part of the autoclave body so that its position can be adjusted, so the structure is simple and assembly is easy. Its effects are remarkable, such as ease of manufacture.
