Abstract

The utility model discloses a high-vacuum cabin body sealing door hinge which comprises a cabin body fixed end hinge base, an end face bearing, a hinge intermediate assembly, a flat head pin, an elastic check ring, a door body fixed end hinge base assembly and a shaft position screw.

Description

High vacuum cabin sealing door hinge

Technical Field

The utility model relates to the technical field of food vacuum cold drying equipment, in particular to a high-vacuum-degree cabin sealing door hinge.

Background

The vacuum freeze-drying equipment for food is a technology for freeze-drying food under low vacuum degree, and the equipment has strict requirement on vacuum degree, so that the requirement on the sealing performance of the equipment is high. The requirement of the equipment on the strength is high, a lot of equipment adopts a welding structure, the bonding surface of the cabin body and the door is difficult to ensure to be absolutely flat during welding, and therefore the sealing surface of the door is required to be adopted to press the elastic sealing rubber strip so as to ensure the sealing of the position where the elastic body is not filled to be flat. The traditional hinge only has one degree of freedom of rotation, so that if the sealing effect is good, the opening and closing of the cabin door are difficult and the operation is not very good due to the large weight of the cabin door, so that the hinge is improved, and the high-vacuum cabin body sealing door hinge is provided.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in fig. 1-5, the high vacuum degree cabin sealing door hinge of the utility model comprises a cabin fixed end hinge base 1, an end face bearing 2, a hinge intermediate assembly 3, a flat head pin 4, an elastic retainer ring 5, a door fixed end hinge base assembly 6 and a shaft position screw 7, wherein a mounting groove is formed on one side of the surface of the cabin fixed end hinge base 1, the hinge intermediate assembly 3 is rotatably mounted in the mounting groove, mounting holes are formed in the surfaces of the mounting groove and the hinge intermediate assembly 3, the flat head pin 4 is mounted in the mounting hole, the elastic retainer ring 5 is clamped and mounted at the bottom end of the flat head pin 4, a plurality of mounting holes are formed in one side of the surface of the door fixed end hinge base assembly 6, the shaft position screw 7 is mounted in the mounting hole, and the door fixed end hinge base assembly 6 is in threaded connection with the hinge intermediate assembly 3 through the shaft position screw 7.

The hinge intermediate assembly 3 includes a hinge intermediate 9 and a sliding shaft 10, and the hinge intermediate 9 and the sliding shaft 10 are connected by interference fit.

The door fixed end hinge base assembly 6 comprises a door fixed end hinge base 11 and a graphite copper sleeve 8, and the door fixed end hinge base 11 is connected with the graphite copper sleeve 8 in an interference fit mode.

The working principle is as follows: according to the high-vacuum cabin sealing door hinge, a cabin fixed end hinge base 1 and a door fixed end hinge base assembly 6 are respectively fixed on a cabin and a door body through bolt connection. The hinge seat 1 at the fixed end of the cabin body, the end face bearing 2 and the hinge intermediate body 3 are connected with the elastic retainer ring 5 through the flat head pin 4 to form a rotary kinematic pair.
