Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an electricity metering box. Background Technology

[0002] In the production process of electrical equipment, electricity meters are often directly installed in electricity metering boxes using screws or bolts and other locking devices. During installation or maintenance, it is necessary to constantly disassemble and reassemble the locking devices. After the operation is completed, the locking devices must be reinstalled, which is cumbersome and inconvenient to use. In addition, the direct contact between the electricity metering box and the electricity meter can easily lead to electrical conductivity, which is not safe. Utility Model Content

[0003] The purpose of this utility model is to provide an electricity metering box. When installing an electricity meter, the hanging block presses down on the inclined surface to drive the stop block to retract and embed the hanging block into the hanging groove. The stop block is then driven by a spring to return, tightly locking the hanging block between the stop block and the hanging groove. When removing the electricity meter, the meter can be removed by pulling the transmission rod outward. The installation and removal of the electricity meter can be completed quickly, and the operation is simple and convenient. Moreover, both the mounting base and the stop block are insulators, which can separate the box body from the electricity meter, ensuring good safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electricity metering box includes a box body and at least one mounting base; an operating port is provided on one side of the box body; the mounting base is installed inside the box body; a hanging groove with a "T"-shaped cross-section is provided on one side of the upper end of the mounting base, and a hanging block with a "T"-shaped cross-section is fixed to the rear end of the electricity meter; the hanging block is tightly embedded in the hanging groove from top to bottom to hang the electricity meter on the mounting base; a limiting hole is provided horizontally on the mounting base above the hanging block; a limiting component is provided on the limiting hole; the limiting component includes a stop block, a transmission rod, a mounting tube, and a spring; the outer wall of the mounting tube is threaded to the limiting hole; the inner end of the transmission rod is fixedly connected to the stop block, and the outer end of the transmission rod is sleeved in the mounting tube and extends outward; the spring is sleeved on the transmission rod between the stop block and the mounting tube; the hanging block is located below the stop block, and the upper end of the stop block is provided with an installation slope; both the mounting base and the stop block are insulators.

[0006] Furthermore, both the mounting base and the stop are made of ceramic.

[0007] Furthermore, the inner wall of the mounting tube is provided with a positioning groove in the axial direction; the outer wall of the transmission rod is fixed with a positioning strip in the axial direction, and the rotation of the transmission rod is restricted by the positioning strip being embedded in the positioning groove.

[0008] Furthermore, a nut is provided at the outer end of the transmission rod; the nut is threadedly connected to the outer end of the transmission rod.

[0009] Furthermore, a support block is fixed to the front side of the lower end of the mounting base, and the lower end of the energy meter abuts against the support block.

[0010] Furthermore, a guide slope is provided at the upper end of the hanging groove.

[0011] Furthermore, the mounting base on the outside of the electricity meter is provided with multiple mounting holes, and mounting bolts pass through the mounting holes to lock the mounting base onto the housing.

[0012] Furthermore, a door is hinged to the box body, and the door cover is located on the operating port.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1. This utility model relates to an electricity metering box. When installing an electricity meter, the hanging block presses down on the inclined surface to drive the stop block to retract and embed the hanging block into the hanging groove. The stop block is then driven by a spring to return, tightly locking the hanging block between the stop block and the hanging groove. When disassembling the electricity meter, the meter can be removed by pulling the transmission rod outward. This allows for quick installation and disassembly of the electricity meter, and the operation is simple and convenient. Furthermore, both the mounting base and the stop block are insulators, which can separate the box from the electricity meter, ensuring good safety.

[0015] 2. This utility model provides an electricity metering box with an axially oriented positioning groove on the inner wall of the mounting tube and an axially oriented positioning strip fixed on the outer wall of the transmission rod. The positioning strip is embedded in the positioning groove to restrict the rotation of the transmission rod, which keeps the mounting slope on the stop block in an upward state. This facilitates the downward pressure of the hanging block on the mounting slope to drive the stop block to retract and embed the hanging block into the hanging groove. However, the upward pressure of the hanging block on the stop block will not drive the stop block to move outward. Furthermore, the nut prevents the transmission rod from slipping off the mounting tube, resulting in good performance.

[0016] 3. The present invention provides an electricity metering box with multiple mounting holes on the mounting base on the outside of the electricity meter. This not only allows the mounting base to be locked onto the box body by passing mounting bolts through the mounting holes, but also prevents the mounting bolts from contacting the electricity meter, thus minimizing electrical conductivity.
