Description

A kind of safe antitheft ammeter box

The utility model has related to electricity consumption measuring apparatus field, is particularly for a kind of safe antitheft ammeter box, is applicable to that various types of families use with ammeter, is particularly useful for the electric card type watt-hour meter that the user buys electricity valuation management voluntarily and uses.

Existing ammeter box mostly is the integral cavity formula table case that a usefulness iron sheet is manufactured, and is made up of casing and chamber door, and it is good that ammeter is put into the case internal fixation, and cover at table and stamp lead sealing, at the chamber door outside locking, the own admin table case of user.This ammeter box brings confusion and loss for the management of electricity consumption because ammeter is to be exposed to the outside fully in case, and the user can cause short circuit to carry out stealing at incoming line by various means and way, and this ammeter box is obviously inadvisable.There is a kind of ammeter box practical, the table case by about the chest of two band doors form, knife switch is housed in the right-hand part, go up lock control by user oneself, ammeter is housed in the left side, on the cabinet door, be provided with a glass window, in order to observe the power consumption indication of ammeter, the below of window has a rectangle gathering hole, power supply cassette ammeter user plug-in card usefulness, and the table case is by lock control on the power supply department.Be extended with fixedly ear in the outside of casing.Though this ammeter box can play certain anti-electricity-theft effect, but structurally with on using still there are some defectives, the unlatching of all ammeter boxes is grasped by power supply department, make troubles and inconvenience obviously can for the management of power supply department, bigger gathering hole is exposed to the outside and is easily filled in foreign matter destruction by other people, casing uses dangerous by fixedly ear is fixing from the outside realization.Therefore, this ammeter box is promoted the use of and is still had many inconvenience.

The purpose of this utility model is to release a kind of novel structure, can effectively prevent stealing, can be user-friendly to ammeter box---the safe antitheft ammeter box of managing with power supply department again,, safety utilization of electric power economical, reasonable with better assurance improve management of power use level.

Task of the present utility model is to realize by the way that installs double-deck case lid on ammeter box additional.Concrete ammeter box is made up of casing and case lid, the rectangle housing of casing for making of an iron sheet or engineering plastics, for the ease of installing and wiring, on the back plate of casing, have the mounting hole of static housing, hook, screw hole and the inlet wire notch of location ammeter, be equipped with in the housing leakage switch support is installed, on two blocks of side plates about casing and base plate, have the notch that rolls off the production line.The case lid of table case is made up of inside and outside two case lids, and interior case lid is the large cover that has a rectangle concave surface above, directly is fixed on the casing equipped with casing with screw.(or up and down) two windows about having on the concave surface of cover plate, in order to holding ammeter and leakage switch, on the periphery of cover plate and concave face plate, have inside and outside twice lead seal hole, a lock nose is arranged on the top of cover plate, equipped with the lockhole that outer container covers, in order to the locking list case.Outer case lid in the utility model is a minor flaps, is can pin on the concave face plate of case lid in being movably connected in, and blocks in order to ammeter, leakage switch and interior lead sealing on the case lid in will being exposed to.Have viewport on the case lid outside, observe at ordinary times, monitor the electricity consumption situation of ammeter for the user.Also be provided with lockhole on the case lid, for user's self-locking table case.In order to satisfy the needs in different user and place, the utility model ammeter box can be made that a plurality of table casees fuse in conjunction with body structure, generally connect together to be integral and be advisable with 2-3 casing, each unit box of combination box is identical with the ammeter box structure of single casing, all have inside and outside two case lids and on interior case lid, offer inside and outside two lead seal holes, ammeter on the interior case lid concave face plate, leakage switch window can be to be left and right sides arranged, and layout also can be arranged above and below.

The utility model is when normal the use, and whole ammeter is covered by inside and outside case lid and sealed, and user's (or power supply department) grasps and understands ammeter electricity consumption situation by the observation slotted hole that covers outward.Be exactly that user's case lid outside opening is when checking ammeter or plug-in card, also can only see the ammeter dial plate, whole ammeter and lead-in wire are all lived by the inner cap block, under the prerequisite of not destroying lead sealing and ammeter, can't implement stealing, effectively prevented the generation of electricity filching behavior, the setting of inside and outside twice lead sealing has prevented that other people from destroying the lead sealing stealing, guaranteed user's Electrical Safety.

The ammeter box that the utility model provides has been owing to designed the case lid of inside and outside two-track tape window and viewport and had inside and outside twice lead seal hole on case lid, make ammeter box have compact conformation, safe and reliable, anti-stealing electricity function is strong, easy to install, be convenient to advantage such as management.
