Background technology
In order to prevent that electric energy meter from being trespassed by the outside, the general needs of electric energy meter programming control section install secret device additional.At present; Lead sealing is means relatively more commonly used, and lead sealing is to be formed by the plumbous cap scolding tin of copper wire (copper wire and galvanized wire combine) with φ 15.5mm, and the program switch lid is locked with the crossed cylinder screw; Pass copper wire (copper wire and galvanized wire combine) through hole of program switch lid and crossed cylinder screw cap then; Then hand over knot to copper wire (copper wire and galvanized wire combine) two-end-point, fill in the plumbous cap groove position by the tight jail of clockwise button again, last scolding tin is locked.The safe and secret structural disadvantages of this kind is: be not easy in inspection table line to add the operation of automatic plastic packaging assembly production chain, can only artificial assemble, complicated operation, time-consuming feed consumption, cost height, efficient are low.
Summary of the invention
The utility model technical matters to be solved provides a kind of secret device of electric energy meter programming control section; Solve the deficiency of existing plastic packaging; Be implemented in the automatic plastic packaging assembly production chain of adding operation in the inspection table line, increase the reliability and the efficient of assembling, reduce cost.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of secret device of electric energy meter programming control section comprises program switch lid, is used for fixing the fixed screw of said program switch lid, the base of fixing with electric energy meter and the loam cake that cooperates with said base; Said base middle part is provided with the screw storage tank that is used for ccontaining said fixed screw, and said screw storage tank both sides are respectively equipped with buckle slot, are provided with stopper in the said buckle slot; Corresponding said buckle slot position, said loam cake bottom surface is provided with buckle, and said buckle is contained in the said buckle slot and with said stopper and offsets.During assembling, earlier base is installed on the electric energy meter, the fixed screw that is used for fixing the program switch lid is accomplished the installation of base after can being contained in the screw storage tank of base; And then on base upper cover loam cake; After covering loam cake, elastic deformation takes place when getting in the buckle slot in the buckle of loam cake, after buckle gets into buckle slot fully; Buckle receives the restriction of stopper in the buckle slot and can not extract once more, so makes loam cake and base strong bonded.Utilize loam cake and cooperating of base that fixed screw is hidden, effectively prevent outside the forcible entry, could open fixed screw only if destroy loam cake.On the other hand, assembling is employed in and adds the operation of automatic integratedization squash type plastic packaging assembly production chain in the inspection table line, has increased the reliability and the efficient of assembling, reduces cost.
As improvement, said screw storage tank both sides are respectively equipped with the buckle bone, and said buckle bone is provided with lug boss, and said lug boss stretches in the said buckle slot.
As improvement; Said buckle is made up of connecting portion, first fixture block and second fixture block; Said first fixture block is connected with said loam cake bottom surface through said connecting portion with second fixture block, and said first fixture block and said stopper offset, and the lug boss of said second fixture block and said buckle bone offsets.After buckle got into buckle slot, second fixture block received the extruding of lug boss, and buckle is squinted to another side, and first fixture block is engaged with stopper, and the completion buckle combines with base.
As improvement, said loam cake bottom surface is provided with some grooves and forms frangible, and when loam cake ran into illegal invasion, frangible face was prone to be destroyed, and can't repair again, is convenient to the maintainer and whether understands electric energy meter by illegal invasion.
The beneficial effect that the utility model is compared with prior art brought is:
Elastic deformation takes place when getting in the buckle slot in the buckle of loam cake, and after buckle got into buckle slot fully, buckle received the restriction of stopper in the buckle slot and can not extract once more, so makes loam cake and base strong bonded.Utilize loam cake and cooperating of base that fixed screw is hidden, effectively prevent outside the forcible entry, could open fixed screw only if destroy loam cake.On the other hand, assembling is employed in and adds the operation of automatic integratedization squash type plastic packaging assembly production chain in the inspection table line, has increased the reliability and the efficient of assembling, reduces cost.

Embodiment
Below in conjunction with Figure of description the utility model is described further.
A kind of secret device of electric energy meter programming control section comprises program switch lid 2, is used for fixing the fixed screw 6 of said program switch lid 2, the base of fixing with electric energy meter 14 and the loam cake 3 that cooperates with said base 4.As shown in Figure 2, said base 4 middle parts are provided with the screw storage tank 15 that is used for ccontaining said fixed screw 6, and said screw storage tank 15 both sides are respectively equipped with buckle slot 12, are provided with stopper 13 in the said buckle slot 12.Said screw storage tank 15 both sides are respectively equipped with buckle bone 14, and said buckle bone 14 has elasticity, and buckle bone 14 is provided with lug boss 11, and said lug boss 11 stretches in the said buckle slot 12.As shown in Figure 1; Corresponding said buckle slot 12 positions, said loam cake 3 bottom surfaces are provided with buckle 7; Said buckle 7 is made up of connecting portion 8, first fixture block 9 and second fixture block 10; Said first fixture block 9 is connected with said loam cake 3 bottom surfaces through said connecting portion 8 with second fixture block 10, and first fixture block, 9 to the second fixture blocks 10 are long, and first fixture block 9 and second fixture block 10 all cooperate formation hook-shaped with connecting portion 8; And first fixture block, 9 ends can offset with said stopper 13, and second fixture block 10 can offset with the lug boss 11 of said buckle bone 14.Said loam cake 3 bottom surfaces are provided with some grooves 5 and form frangible, and when loam cake 3 ran into illegal invasion, frangible face was prone to be destroyed, and can't repair again, was convenient to the maintainer and whether understood electric energy meter 1 by illegal invasion.
