Description
Technical field
The utility model relates to a kind of data digging system, especially relates to one and to oppose electricity-stealing ammeter.
Background technology
After entering 21 century, the level of informatization of human society is more and more higher, informationized society is entered gradually from industrialization society, the infotech of rising with the transformation of social pattern and related application thereof allow the every aspect of society create the change of matter, wherein also comprise electric system, " oppose electricity-stealing " as the FAQs of in electric system, its whole content also there occurs change thereupon.
Current ammeter comprises the base be fixed on body of wall, is located at base top for holding the upper outlet body of ammeter and being located at base bottom for holding the lower cover of user's operating item, upper and lower cover body and base releasable connection.During use, user can open the plug-in strip of lower cover to its inside, the user operation parts such as leakage switch operate, and upper outlet body can only be opened by electric power maintenance personnel, locking device poor stability between cover body and base, ammeter is arranged on open air and is easy to cause ammeter stolen, sneak current to prevent lawless person, the method of current employing is after tighting a bolt, bolt hole is shut by the method for ultrasonic soldering by mounting hole made of plastic, bolt cannot be opened, but the sealing of hole sheet that plastics are made easily is copied, be arranged on ammeter and be also not easy to be found, electric administrative department is difficult to find this table by stealing.
Summary of the invention
The purpose of this utility model is exactly provide a kind of easy for installation to overcome defect that above-mentioned prior art exists, and use simple, cost is low, is easy to the ammeter of opposing electricity-stealing checking out whether ammeter is sneaked current.
The purpose of this utility model can be achieved through the following technical solutions: one is opposed electricity-stealing ammeter, comprise box-type watchcase (1), watchcase (2) is provided with safety door (3), this safety door (3) is provided with safety lock, safety lock comprises lock body (4) and shank of the key (5), shank of the key (5) inserts locking in lock body (4), it is characterized in that, described safety door (3) periphery is provided with Two-dimensional electron code sheet metal (2), is provided with and is provided with FRID chip in described lock body (4).
Described lock body (4) has an opening, extends to form an opening draw-in groove along opening in lock body, the shape of opening draw-in groove, size and described shank of the key (5) adapt.
Described lock body (4) is provided with latch (6), and described shank of the key (5) is provided with the elastic card (7) mating clamping with latch (6).
Compared with prior art, the utility model is easy for installation, and use simple, cost is low, is easy to check out whether ammeter is sneaked current.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model lock body shank of the key partial schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Fig. 1 ~ 2, one is opposed electricity-stealing ammeter, comprise box-type watchcase 1, watchcase 2 is provided with safety door 3, this safety door 3 is provided with safety lock, and safety lock comprises lock body 4 and shank of the key 5, and shank of the key 5 inserts locking in lock body 4, described safety door 3 periphery is provided with Two-dimensional electron code sheet metal 2, is provided with and is provided with FRID chip 8 in described lock body 4.
Described lock body 4 has an opening, extends to form an opening draw-in groove along opening in lock body, the shape of opening draw-in groove, size and described shank of the key 5 adapt.Described lock body 4 is provided with latch 6, and described shank of the key 5 is provided with the elastic card 7 mating clamping with latch 6.
By in shank of the key 5 insertion opening draw-in groove during use, press shank of the key 5 and make elastic card 7 snap in latch 6 can to pin.Be provided with on FRID chip 8 in lock body, can carry out information locking and tracking, and be difficult to remove because this FRID chip 8 is arranged in lock body, therefore, antifalse effect is good.In addition, easy for installation, use simple, cost is low, judges whether ammeter is sneaked current by Two-dimensional electron code sheet metal.
