Abstract
The utility model discloses a device for automatically recording number of box opening times of an electric meter box through the electric meter box, which comprises a bottom column, a support and a button which are successively connected from bottom to top. The bottom column is fixed in the lower box of the electric meter box. A press block which corresponds with the position of the bottom column is fixed in the upper box of the electric meter box. The button is elastic, and the lower end of the button is connected with two leads which are connected with auxiliary terminals of the electric meter. Recording for the number of box opening times of the electric meter box is realized through pressing down the button or connecting/disconnecting the leads with the electric energy meter in a loosen state. When the electric meter normally works, the electric energy box is locked; the press block presses down the button for switching on the lead; and a loop is formed between the leads and the electric meter. When the upper box of the electric energy meter is opened, the press block in the upper box is separated from the button; the button rebounds for switching off the leads; and the electric meter detects switching-off of the leads, automatically stores and adds one box opening record in a liquid crystal screen displaying area; so that box opening record of personnel can be checked in a record, or analysis for checking whether illegal electric meter opening operation exists is facilitated, thereby finding electric energy theft in time.
Description
Technical field
The utility model relates to a kind of ammeter box, is specifically related to a kind of by the device of the unpacking number of times of the automatic recording electrical meter case of ammeter.
Background technology
After ammeter work a period of time, need to detect maintenance, to ensure its normal accurate-metering and to show user's power consumption.Because ammeter is in use likely placed on outdoor rugged surroundings, or prevent the equiprobable hazardous act of illegal operation, so ammeter generally all by power department staff by ammeter box by it under lock and key, to strengthen protection.Current ammeter box does not all also have the writing function of opening times, and power department staff cannot judge its repair rate or illegally open the power stealing behavior of table case.
Utility model content
It is a kind of by the device of the unpacking number of times of the automatic recording electrical meter case of ammeter that the purpose of this utility model is to provide, and is convenient to analyze in time have or not power stealing behavior to occur.
The utility model is disclosed this by the device of the unpacking number of times of the automatic recording electrical meter case of ammeter, comprise from the bottom up the foundation, pillar and the button that connect successively, foundation is fixed in the lower box of ammeter box, in the upper box of ammeter box, be fixed with the briquetting corresponding with foundation position, button is elastic button, and its lower end is connected with two wires that are connected with ammeter auxiliary terminal.
In the axial center hole of described foundation, there is embedded nut.
Described pillar is the cylinder of hollow, has the slotted hole about axial centre face symmetry on the length direction of its sidewall.
Described wire is connected with ammeter after passing the slotted hole on described pillar.
The crisscross screw that has external diameter to mate with described embedded nut internal diameter in the center pit of described pillar, is connected fastening by the cooperation of crisscross screw and embedded nut by described pillar with foundation.
Principle of work of the present utility model is as follows: by button depress or releasing orientation makes wire be communicated with ammeter or disconnects and realize the unpack record of number of times of ammeter box.When ammeter is normally worked, ammeter box is locked, and button down is made the closing of polygon by briquetting, forms a loop between wire and ammeter.When the upper box of ammeter box is opened, briquetting on it leaves button, button resilience disconnects wire, ammeter detects that wire disconnects, automatically deposit in and accumulate once open case record in liquid crystal display viewing area, staff's open case record is had good grounds, or be convenient to analyze whether have and illegally open ammeter box operation, find in time power stealing behavior.
Brief description of the drawings
Fig. 1 is blast structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is disclosed this by the device of the unpacking number of times of the automatic recording electrical meter case of ammeter, comprise from the bottom up the foundation 1, pillar 2 and the button 3 that connect successively, foundation 1 is fixed in the lower box of ammeter box, is fixed with the briquetting 4 corresponding with foundation 1 position in the upper box of ammeter box.
In the axial center hole of foundation 1, there is embedded nut 5.The cylinder that pillar 2 is hollow, has the slotted hole about axial centre face symmetry on the length direction of its sidewall.Button 3 is elastic button, and its lower end is connected with two wires 6, after the slotted hole that wire 6 passes on pillar 2, is connected with the auxiliary terminal of ammeter.
Prop up the crisscross screw 7 that has external diameter to mate with embedded nut 5 internal diameters in the center pit of 2 posts, by the cooperation of crisscross screw 7 and embedded nut 5, pillar 2 is connected fastening with foundation 1.
Principle of work of the present utility model is as follows: by button 3 depress or releasing orientation makes wire 6 be communicated with ammeter or disconnects and realize the unpack record of number of times of ammeter box.When ammeter is normally worked, ammeter box is locked, and briquetting 4 is depressed button 3 to make the closing of polygon, forms a loop between wire 6 and ammeter.When the upper box of ammeter box is opened, briquetting 4 on it leaves button 3, button 3 resiliences disconnect wire 6, ammeter detects that wire 6 disconnects, automatically deposit in and accumulate once open case record in liquid crystal display viewing area, staff's open case record is had good grounds, or be convenient to analyze whether have and illegally open ammeter box operation, find in time power stealing behavior.
