Meter Box Locking Assembly Tool-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for utility meter boxes are difficult to install quickly and safely, as they require users to reach into the meter box and expose themselves to electrical components, increasing the risk of electrical shock and taking too much time.
Innovation Solution
A locking assembly with a mounting bracket and locking bracket that uses a hooking structure to secure the cover over the meter box opening without requiring tools or access inside the box, featuring a stud and barrel lock mechanism for easy installation and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used to secure the mounting bracket to the meter box, then the bracket is firmly attached, but the installation becomes time-consuming and requires reaching into the box near electrical components
Solution Approach 1:
The mounting bracket is divided into separate components: the bracket body and the screw, allowing the bracket to be positioned first and the screw to be inserted later through an accessible opening, eliminating the need to reach into the electrical box during bracket installation
Solution Approach 2:
A long access opening is provided in the meter box wall that serves as an intermediary pathway, allowing the screw to be inserted from the outside while still reaching the mounting bracket inside the electrical box, thus avoiding direct contact with electrical components
2Reliability
If a screw is used to secure the mounting bracket, then the bracket is firmly attached, but the user is exposed to electrical components increasing shock risk
Solution Approach 1:
The installation process is segmented into two separate actions: first positioning the bracket (no exposure to electricity), then inserting the screw through a protected opening (still no exposure to electricity), thereby eliminating electrical shock risk while maintaining firm attachment
Solution Approach 2:
The access opening acts as an intermediary that allows the screw to pass through the meter box wall without requiring the user to reach into the electrical box, thus providing firm attachment while protecting the user from electrical shock
3Reliability
If a traditional locking device is used, then the meter box can be secured, but the installation process is complex and time-consuming
Solution Approach 1:
The locking device is segmented into a mounting bracket and a locking bracket that can be installed independently, with the locking bracket being attached to the cover from the outside, simplifying the overall installation process while maintaining security
Solution Approach 2:
Instead of installing the locking mechanism from the inside of the electrical box, the locking bracket is installed from the outside on the cover, reversing the traditional approach and greatly simplifying the installation process

AI summary
A locking assembly for locking a cover over an opening of an enclosure includes a mounting bracket including a first wall having opposing first and second ends, a second wall joined to said first end and extending in a first direction away from the first wall. A stud joined to the first wall extends in a second direction away from the first wall. Hooking structure extends from the second wall of the mounting bracket for extending into the opening of the enclosure and engaging the enclosure to secure the mounting bracket relative to the enclosure. A locking bracket includes a first wall having opposing first and second ends and a first surface facing the first wall of the mounting bracket. A second wall is joined to the first end of the mounting bracket and extends in a first direction away from the first wall of the locking bracket. In one embodiment, a lock housing is fixed to the first wall of the locking bracket. The lock housing defines a cavity for receiving a barrel lock and an opening intersecting said cavity. The opening receives the stud for engaging the barrel lock received in the cavity.
