Above-mentioned water meter outer lead compartment, wherein, described lower cover comprises the first column b and the second column b, the length of described first column b is less than the length of described second column b, spacing b is formed between described first column b and described second column b, described O-ring seal b is arranged in described spacing b, described second column b is arranged in described spacing a, the top end face of described second column b contacts with the bottom end face of described O-ring seal a, described first column a is arranged in described spacing b, the bottom end face of described first column a contacts with the top end face of described O-ring seal b.
Above-mentioned water meter outer lead compartment, wherein, the outside wall surface of described first column a and the outside wall surface same level of described first column b are arranged.
Above-mentioned water meter outer lead compartment, wherein, forms the angle of 45 DEG C between the dip plane of described buckle and surface level.
Above-mentioned water meter outer lead compartment, wherein, described buckle is provided with multiple draw-in groove for placing wiring board from top to bottom.
Above-mentioned water meter outer lead compartment, wherein, is also provided with coupled, for supporting reinforcement in the side of described buckle.
Compared with prior art, the utility model has the following advantages:
The utility model has the advantages such as structure is simple, cost is low, easy installation.Because upper cover adopts the mode fastened to be arranged on the top of lower cover, and between upper cover and lower cover, be also arranged with two O-ring seals, therefore, the sealing effectiveness of compartment entirety can be improved, thus avoid water to enter its inside by the gap of box body;
By being arranged on multiple buckles of upper cover bottom end face, wiring board can be made to stablize, be arranged in compartment efficiently.

Embodiment
The water meter outer lead compartment that the utility model provides comprises upper cover and is fastened on the lower cover bottom it, upper cover with under cover and be arranged with O-ring seal a and O-ring seal b respectively, in the bottom of upper cover, multiple buckle for placing wiring board is installed.
As shown in Figures 1 and 2, upper cover 1 is fastened on lower cover 4, and is fixed by screw 6.Upper cover 1 comprises the first column a7 and the second column a8, and wherein, the first column a7 is arranged on the outside of the second column a8.The length of the first column a7 is greater than the length of the second column a8, and between the first column a7 and the second column a8, be formed with spacing a13, O-ring seal a2 is arranged in spacing a13.
Lower cover 4 comprises the first column b9 and the second column b10, and wherein, the first column b9 is arranged on the then outer of the second column b10.The length of the first column b9 is less than the length of the second column b10, and between the first column b9 and the second column b10, be formed with spacing b14, O-ring seal b3 is arranged in spacing b14.Second column b10 is arranged in spacing a13, and the top end face of the second column b10 contacts with the bottom end face of O-ring seal a2.First column a7 is arranged in spacing b14, and the bottom end face of the first column a7 contacts with the top end face of O-ring seal b3.
Owing to being arranged with two O-ring seals between upper cover and lower cover, therefore, the measure of twice waterproofing protection is formed.
The outside wall surface of the first column a7 and the outside wall surface same level of the first column b9 are arranged.
In the present embodiment, the buckle 5 be arranged on upper cover bottom end face has four.Wherein, in each buckle, be provided with multiple draw-in groove 11 for placing wiring board from top to bottom.In addition, the dip plane in buckle and form the angle of 45 DEG C between surface level.
Also be provided with in the side of each buckle 5 coupled, for that support, leg-of-mutton reinforcement 12, wherein, the angle of the bottom angle of triangle reinforcement is 45 DEG C.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
