Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can prevent by the electric energy meter pried open.
For achieving the above object, the utility model provides following technical scheme: a kind of electric energy meter, include the rectangular parallelepiped housing be made of plastics, described enclosure interior hollow is formed with container cavity, described container cavity is formed with opening at the end face of described housing, removably be covered with lid over said opening, described lid is provided with fixed head, described fixed head offers observation window, also include first to renovate, described first to renovate one end be stiff end, described fixed end cap is connected in a rotating shaft, described rotating shaft is fixed on described fixed head, described first other end renovated is free end, described free end can overturn around described rotating shaft, described free end is provided with slot, described fixed head offers the fastener with described slot adaptation,
Offer deep-slotted chip breaker in described lid side, be embedded with second and renovate in described deep-slotted chip breaker, described second renovates one end is formed with the arc strip with described deep-slotted chip breaker adaptation, and described arc strip can slide along cambered surface in described deep-slotted chip breaker;
Described fixed head offers through hole, described second arc strip renovated is provided with vertical fixed leg, described fixed leg extends in described fixed head top through described through hole, and described first renovate cover on described fixed head time, described first renovate can the top of stationary shaft described in pressing; Renovate described second and be provided with erection column, described erection column hollow is formed with via, in described via, offer internal thread.
As improvement of the present utility model, described removably lid is established and is referred to described housing offers at least two the first threaded holes, described lid offers the pilot hole identical with described first threaded hole quantity, and each pilot hole all faces first threaded hole, in described pilot hole and the first threaded hole, be equipped with bolt.
As further improvement of the utility model, described fixed head also offers the second threaded hole, described first renovates and offers mounting hole, and when described first renovate cover on described fixed head time, described mounting hole and described second threaded hole just right.
Compared with prior art, the utility model has the advantage of: there is multiple flip structure lid is protected.Lid is prized by force once artificial, the linkage structure between each cover plate and lid can be made to lose efficacy, and then cause the destruction of irrecoverability, thus maintenance personal and other staff can be found by situation about prizing the very first time, carry out keeping in repair and investigating.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of electric energy meter in the utility model;
Fig. 2 is the using state schematic diagram of electric energy meter in the utility model embodiment;
Fig. 3 is the electric energy meter using state schematic diagram in the utility model embodiment under another kind of state.
Embodiment
With reference to Fig. 1-Fig. 3, the embodiment of electric energy meter in the utility model is described further.
As shown in Figure 1, the present embodiment is a kind of electric energy meter, includes the rectangular parallelepiped housing 1 be made of plastics, and described enclosure interior hollow is formed with container cavity, can put into the relevant accessory of ammeter as wiring board and chip etc. in above-mentioned container cavity.
Described container cavity is formed with opening 11 at the end face of described housing, removably be covered with lid 2 over said opening, described lid is provided with fixed head 3, described fixed head offers observation window 31, user can by information such as the readings of instrument in observation window reading power meters, in order to prevent dust etc. from entering into ammeter housing, observation window is provided with glass or transparent plastic etc., ammeter housing and the external world are completely cut off.
Described electric energy meter also includes first and renovates 4, described first to renovate one end be stiff end 41, described fixed end cap is connected in a rotating shaft 42, described rotating shaft 42 is fixed on described fixed head 3, described first other end renovated is free end 43, described free end can overturn around described rotating shaft, and described free end is provided with slot 431, and described fixed head offers the fastener 31 with described slot adaptation;
