Problems solved by technology

The above-mentioned various objects may involve various environments in application. The original design may not take into account the protection requirements of the new environment or when the protection of the original design fails, it also needs to be re-sealed. However, the existing sealing protection is complicated and has poor reliability. not easy to achieve

Embodiment 1

[0019] like figure 1 As shown, the protected part is the connection between the optical cable plug and the socket, and the sealing and protection method includes the following steps:

[0020] (1) Carry out profiling and enlarging design on the shape of the junction of the optical cable plug 6 and the socket 7 and make the corresponding shell skeleton 1, the shell skeleton 1 is a half-cut shape, which can clamp the junction of the optical cable plug 6 and the socket 7 , the two contact and position, and form a certain gap with the protected part;

[0021] (2) The shell frame 1 split in half is installed at the junction of the optical cable plug 6 and the socket 7. Apply adhesive to the contact part of the connection between the skeleton 1 and the optical cable plug 6 and the socket 7, so that the gap space between the shell skeleton 1 and the optical cable plug 6 and the socket 7 is basically closed;

[0022] The shell frame 1 split in half is clamped to the junction of the o...

Embodiment 2

[0027] like figure 2 As shown, the part to be protected is a right-angled elbow pipeline 8 elbows, and its sealing and protection method includes the following steps:

[0028] (1) Carry out profiling and enlarging design on the shape of the bend pipe 8 at right angles, and make the corresponding shell frame 1. The shell frame 1 is a half-cut shape, which can clamp the bend pipe line at right angles. 8 At the elbow, the two are positioned in contact and form a certain gap with the part of the guard;

[0029] (2) The shell frame 1 split in half is installed at the right-angled elbow pipeline 8 bends, when the shell frame 1 split in half is installed, the butt joint surface of the shell frame 1 split in half The shell skeleton 1 and the right-angled elbow pipeline 8 are coated with adhesive on the contact part, so that the gap space between the shell skeleton 1 and the right-angle elbow pipeline 8 is basically closed;

[0030] Clamp the shell frame 1 that has been cut in half ...

Abstract

The invention discloses a sealing method, in particular a sealing protection method. The method is characterized in that profile of the appearance of the position requiring protection is modeled and amplified so as to prepare corresponding shell framework which is half-split; the part to be protected is clamped; a clearance in sealing state is formed between the two shell frameworks; a high through hole and a low through hole are drilled on the framework; a hole plug matched with the aperture is designed; adhesive or sealant is injected into the clearance through the low through hole by an injector; when the adhesive or the sealant bursts out of the high through hole, the high through hole is plugged by the hole plug, the injector is pulled out and the low through hole is plugged by the hole plug. The method is simple and reliable, can be widely applicable to the sealing protection of a plurality of articles, can extend the usage environment range of the article to be protected and can carry out repairing when the protection of the article to be protected is invalidated.

Description

technical field [0001] The invention belongs to a sealing method, in particular to a sealing protection method. Background technique [0002] In various industrial application fields and daily life, it often involves the sealing of various objects such as electrical connectors, optical cable connection plugs, pipeline connections, etc., in order to isolate various media and dust from the outside world and prevent internal media. The role of leakage. The above-mentioned various objects may involve various environments in application. The original design may not take into account the protection requirements of the new environment or when the protection of the original design fails, it also needs to be re-sealed. However, the existing sealing protection is complicated and has poor reliability. Not easy to achieve. Contents of the invention [0003] The purpose of the present invention is to provide a simple and reliable sealing protection method. [0004] Realize the techn...
