Through the setting of second sealing member, further improve holistic sealed effect.

Wherein, be equipped with first vertical part on the upper cover, first vertical part is connected through first horizontal part and first portion of stretching into and is formed the structure of falling U style of calligraphy, and first vertical part is located the outside of base outer wall and is parallel arrangement with the base outer wall.

Adopt the setting of first vertical part, play and shelter from the effect, prevent that outside liquid from entering into to the base in.

Wherein, the first vertical part is consistent with the first extending part in length.

The two are arranged with the same length, so that the processing is more convenient.

And a third sealing element is arranged between the first vertical part and the outer wall of the base.

Through the setting of third sealing member, further improve holistic protection level, guarantee through the multilayer protection in the use, outside liquid hardly gets into to the base in.

Wherein, the third sealing member is formed on the base by secondary injection molding.

Through the setting of twice moulding plastics for fixed effect between third sealing member and the base is better, and the third sealing member need not to assemble moreover, reduces the installation procedure.

The third sealing element is positioned on a side wall of the base facing upwards.

Because the whole back of installing of ammeter case, top one side is holistic top surface promptly, and the top surface is the face that the rainwater erodees most, so sealing strength is greater than other all the other faces on this face for whole seal structure is better.

Detailed Description

Example 1:

referring to fig. 1-4, an electric meter box with a sealing structure comprises an upper cover 1 and a base 2. Here, the base 2 is integrally disposed, and two cavities are disposed in the base 2 and respectively correspond to the two upper covers 1, and since the structure between the upper covers 1 and the base 2 is the same, only one of the upper covers 1 will be described.

1 right-hand member of upper cover is connected with base 2 with the rotary type, and the other end is fixed with base 2 for upper cover 1 has formed the connection of hinge with base 2, and the connection can pass through hinge connection here to rotate, also can be connected through the pivot, and it is here not adding repetitious description.

The base 2 is provided with a first protrusion 21 and a first groove 22, the first protrusion 21 is located outside the first groove 22, specifically, the first protrusion 21 is located on the outermost side of the base 2, and the first protrusion 21 is provided with a second sealing element 4 on one side facing the upper cover 1. The first groove 22 is provided with a first sealing element 3, and the first sealing element 3 is provided with a second groove 31, where it should be noted that the first sealing element 3, the second sealing element 4, and the third sealing element 5 all have certain elasticity.

The base 2 is provided with a third sealing element 5 on the side facing the first vertical portion 13, where the third sealing element 5 is formed on the outer wall of the base 2 by two-shot injection molding, and here the third sealing element 5 is preferably formed by two-shot injection molding through a TPE injection molding process. Through the setting of twice moulding plastics for the fixed effect between third sealing member 5 and the base 2 is better, and third sealing member 5 need not to assemble moreover, reduces the installation procedure.

The upper cover 1 is provided with a first extending part 11 and a first horizontal part 12, the first extending part 11 is vertical downward, one end of the first horizontal part 12 is vertically connected with the first extending part 11, the other end extends towards the side surface of the upper cover 1, and the first horizontal part 12 is matched with the first bulge 21 to form a sealing structure.

After the upper cover 1 is matched with the base 2, the first extending portion 11 extends into the second groove 31, at least one half of the first extending portion 11 extends into the second groove 31, and preferably two thirds of the first extending portion 11 extends into the second groove 31. Further, the first extending portion 11 is provided with a small lower portion and a large upper portion. Adopt big setting in the end down, play the guide effect, secondly for it is inseparable to stretch into to be connected between portion 11 and the second recess 31 for first, because first sealing member 3 self possesses certain elasticity, so both cooperate the back, and sealed effect is better.

A multi-layer sealing structure is formed between the first horizontal portion 12 and the first protrusion 21 by the second sealing member 4.

Further, a first vertical part 13 which faces vertically downwards is arranged on the upper end of the upper cover 1, wherein the upper end specifically refers to the topmost surface after the whole electric meter box is hung on a wall, namely the surface which is most easily drenched by rainwater or other liquid.

The first vertical portion 13 is parallel to the outer wall of the base 2, and when the cover 1 is engaged with the base 2, the first vertical portion 13 is located outside the outer wall of the base 2. The first vertical portion 13 is connected to the first extending portion 11 through the first horizontal portion 12 to form an inverted U-shaped structure, that is, the first vertical portion 13 is vertically connected to the first horizontal portion 12, and the length of the first vertical portion 13 is the same as that of the first extending portion 11.

The third sealing member 5 is located between the first vertical portion 13 and the outer wall of the base 2, forming a multiple sealing effect. And the arrangement of the first vertical part 13 forms a shielding effect to prevent external liquid from entering the base 2.

Here, the first vertical portion 13 is not provided below the upper cover 1, which provides an effect of saving material cost.

Adopt this kind of structure setting, at first through the setting of first arch 21 and first recess 22, the effect of cascaded isolation has been formed, separate the shelves with outside liquid most on whole outside, be equipped with the setting of first sealing member 3 on the first recess 22, improve holistic sealed effect, be equipped with second recess 31 on the first sealing member 3, and the first portion 11 and the cooperation of second recess 31 of stretching into of upper cover 1, set up second sealing member 4 between first arch 21 and the first horizontal part 12, first vertical part 13 sets up third sealing member 5 with 2 outer walls of base, form the sealed effect of multilayer isolation, improve holistic seal structure, adopt the sealed isolation of multilayer, the sealed effect of holistic has been improved, guarantee the ammeter case in the use, difficult situations such as seepage take place.
