Embodiment 1

[0041] A sealing device with a convenient loading and unloading cover, comprising a three-dimensional box body 1 with a box opening and a box cover 2, including a three-dimensional box body 1 with a box opening and a box cover 2, and a box cover is connected to the inside of the box opening The rectangular frame 3 that provides support, the upper end surface of the rectangular frame is lower than the port of the box body, the box cover is a rectangular flat plate with a shape corresponding to the box mouth, and its four side end faces are 45° inclined planes, and the box cover is connected to the inside of the box body. There is a small gap, and there is a small hole 21 for vacuuming on the box cover, and a detachable vacuum suction cup 7 is connected to the small hole, and the vacuum suction cup has a threaded joint for connecting the air pipe ； The outer periphery of the box is provided with a rectangular iron hoop 5 for reinforcing the box and reducing the deformation of the...

Embodiment 2

[0045] The sealing method of the above-mentioned sealing device with a convenient loading and unloading cover comprises the following steps:

[0046] (1) Apply a continuous and uniform layer of thin glass glue on the 45-degree slope on the four sides of the box cover;

[0047] (2) Take a thin-walled plastic cloth that is not bonded to the glass glue, and apply a layer of wax oil on the plastic cloth;

[0048] (3) Before the glass glue starts to harden, cover and tighten the box cover coated with glass glue with the above-mentioned plastic cloth, so that there are no wrinkles and breaks on the edge of the bevel;

[0049] (4) Apply a continuous and uninterrupted layer of glass glue on the top surface of the rectangular frame of the box to form a 45° slope;

[0050] (5) Before the glass glue starts to harden, slowly join and press the box cover covered with plastic cloth with the 45° inclined glass glue on the top surface of the rectangular frame:

[0051] A. Grasp the pressin...

Abstract

A sealing device with a stubborn unloading cover, including a three -dimensional box and box cover with the box mouth, is connected to the inner side of the box to provide a rectangular border to provide support for the box cover.Cover the small holes that are used for vacuum, and the small holes are connected with a vacuum suction cup that can be convenient for disassembly.The sealing method of this sealing device includes the following: apply glass glue on the 45 -degree slope of the four sides of the box lid; cover and tighten the box cover with plastic cloth to the box cover before the glass glue starts to harden.Apply it to a 45 ° diagonal glass glue, combine the lid with the slope glass glue, press, press, reduce the box cover, and tear off the plastic cloth; then cover the box cover according to the original corresponding position, and the vacuum is vacuum.This sealing device is reliable and tightly connected, convenient to connect to the outside, convenient opening and closing the lid, good sealing and reliable, small deformation of the box, and no collapse.

Description

technical field [0001] The invention relates to a test device and a sealing method, in particular to a sealing device with a convenient loading and unloading cover for vacuuming experiments and a sealing method thereof. Background technique [0002] For some special experiments, there are strict requirements on the box where the experimental equipment is arranged: 1. The box needs to be vacuumed, and the box must be sealed; 2. The box needs to be connected to the outside world through pipelines; 3. It needs to be frequently Open and close the box cover for repeated placement or removal of equipment. At present, there is no sealing device that can meet the above requirements. In the existing experimental sealing device, the two adjacent side plates are mostly connected by bolts. The number of connecting bolts is large, and it is troublesome to disassemble and install; the seal is not strict and easy to leak; Moreover, it is not suitable for occasions that require strict oper...
