Antenna installation hole sealing plug for power system and using method thereof

Abstract

The invention relates to an antenna mounting hole seal plug for a power system, comprising a plug body, a conical sleeve, a locking jaw disc, a sealing set, and a protective vertical tube; the plug body comprises an outer plug, a circular cavity, an inner plug, a screw, a receiving passage, a first circular plate, a first convex ring, a screwing tube and a retaining block; the conical sleeve is provided with a receiving hole, a second circular plate and a second convex ring; the locking jaw disc includes a nut, a support jaw, a ball support and a ball; the sealing set sleeves the outer wall of the outer plug and includes a disc spring, an upper ring and a lower ring from top to bottom, the lower end surface of the upper ring is upwardly recessed gradually to the inside in the radial direction, and the lower ring is a wedged ring with wide inside and narrow outside; the protective vertical tube at least includes a wide tube made of hard material and screwed to the screwing tube, and a narrow tube made of elastic material and arranged on the wide tube; the plug provides regular maintenance for its sealing by using double-layer sealing, can support an antenna to prevent its breakage and also has anti-theft function.

Description

technical field [0001] The invention relates to the technical field of sealing devices, in particular to a sealing plug for an antenna installation hole in a power system and a method for using the same. Background technique [0002] During the operation of the power system, it is often encountered that the electronic instrument installed in the meter box needs to set up an antenna. At this time, it is necessary to open a mounting hole on the upper end of the metal meter box, and then lead the antenna out through a mounting hole, but directly The punching method destroys the airtightness on the top of the watch box, so that the outside rainwater can easily flow into the watch box through the installation hole when it rains, and damage the electronic equipment in the watch box. Therefore, it is necessary to install a sealing plug at the installation hole. [0003] The application date is 2015.06.23, and the patent application number 201520431941.0 discloses an antenna plug fo...

AI Technical Summary

Problems solved by technology

[0004] However, the above scheme has the following problems: 1. The antenna plug is an elastic plug, which is directly inserted into the mounting hole and sealed by tight extrusion between the antenna plug and the mounting hole. However, due to problems such as antenna swing and elastic plug aging, the The tightness between the elastic plug and the mounting hole gradually decreases, and in severe cases, the elastic plug may even come out; 2. The antenna plug lacks a support and protection structure for the antenna. Since the antenna has a certain length, it is easy to be exposed to wind under the action of the wind. Bending occurs; 3. The antenna plug is fixed by friction force, and the fixing force is poor, so the antenna plug and the antenna are easy to be stolen
