AI Technical Summary

Technical Problem

Existing electricity meters lack effective anti-theft devices, resulting in electricity bill losses and safety hazards. Traditional designs have significant security shortcomings and cannot effectively prevent electricity theft.

Method used

An anti-theft and locking mechanism was designed, including a mounting block, a support plate, a connecting rod, a spring, a movable plate, a fixed block, a limit plate, bolts, and a wedge block. The meter box is double-locked by specially manufactured bolts and grooves to prevent unauthorized opening.

Benefits of technology

This improves the security of electricity meters, enabling them to identify electricity theft and effectively prevent the meter box from being forcibly broken into, thus enhancing the anti-theft function of the meters and improving the safety of users' electricity use.

Abstract

本实用新型公开了一种防窃电功能的密封式电表,防盗机构包括固定连接于电表箱一侧中部的安装块,安装块的内壁开设有安装槽,安装槽的内部固定连接有两个支撑板,两个支撑板一侧的两端均穿插连接有第一连接杆,每个第一连接杆的外壁均套设有弹簧,每两个第一连接杆的一侧均固定连接有活动板,本实用新型,特殊制造的螺栓的一端会进入到固定块一侧的凹槽的内部,并且会对凹槽进行挤压,当对凹槽进行挤压时,使其高度会高于安装块的内部,进而达到固定的目的,当有人想要窃电时,若使用仿冒的螺栓进行固定时,其则会达不到相应的位置,内部的凹槽则不会受到挤压,两端的限位板也不会伸出,从而可以更加方便地识别出有人想要窃电的目的。
