Description

Dustproof and waterproof meter box

technical field

The utility model belongs to an electric meter box, in particular to a dustproof and waterproof electric meter box.

Background technique

Existing electric meter box is mostly made of iron sheet, has the box bottom and the box cover to form by hinge connection. The edge of the box cover is made with flanging, so that it can play a sealing role when it is buckled with the bottom of the box. However, the dustproof and waterproof sealing effects of this structure are not ideal enough, and it is difficult to ensure the safe use of the meter box for a long time in relatively harsh environments such as rural outdoor open-air environments. In addition, the existing electric meter box also has disadvantages such as poor visibility and difficulty in replacing internal wearing parts.

Contents of the invention

In order to solve the above-mentioned defects in the prior art, the purpose of this utility model is to provide a dustproof and waterproof electric meter box with good sealing structure and dustproof and waterproof effects, so that it can be used in harsh environments such as outdoors in rural areas .

In order to achieve the above purpose, the technical solution adopted by the utility model is: the dustproof and waterproof electric meter is composed of a box bottom and a box cover to form an electric meter box, and the box bottom and the box cover are connected by hinges, and the feature is that the box bottom and the box cover are combined There is a sealing structure at the bottom of the box. The sealing structure is made of an L-shaped frame with a groove in the cross section for the edge of the box bottom. The edge of the box cover has a card platform that can extend into the groove and form a sealing structure together with the groove.

A flexible sealing strip is arranged in the groove at the bottom of the box.

The cross-sectional shape of the groove at the bottom of the box is V-shaped.

The beneficial effect of adopting the above technical solution is: the dustproof and waterproof electric meter is composed of a box bottom and a box cover, and there is a sealing structure at the junction of the box bottom and the box cover. There is a card platform on the edge of the cover. When the box cover is closed, the card platform on the box cover can extend into the groove of the bottom frame of the box, so that the matching gap is twisted and turned to form a sealed structure, which increases the travel of external dust and rainwater entering the meter box. distance, forming an ideal labyrinth sealing effect, a flexible sealing strip is provided in the groove of the bottom of the box, which plays a good sealing role, and at the same time, the flexible sealing strip under pressure deforms to both sides, filling the side of the buckle between the box cover and the bottom of the box The gap further plays a sealing effect, and the groove at the bottom of the box is V-shaped, which can facilitate the flow of water entering the gap. Therefore, it can effectively prevent dust and water, and keep the meter box clean and dry even if it is used in a harsh environment.

Description of drawings

Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail.

Fig. 1 is the structural representation of the dustproof and waterproof electric meter box of the present utility model.

Figure 2 is a partial cross-sectional view of the enlarged edge section when the meter box is closed.

Detailed ways

The dustproof and waterproof electric meter box shown in Figures 1 and 2 is composed of a box bottom 1 and a box cover 2. The box body is formed by connecting the box bottom 1 and the box cover 2 through hinges. There is a glass observation window 3 on the top, which can observe the working conditions of the internal devices at any time without opening the box, find faults in time, and can observe signs of stealing and leakage, so as to take preventive measures in time. The frame at the bottom of the box is made into an L-shaped frame 4 in cross-section. The L-shaped frame 4 has a groove 5. The cross-sectional shape of the groove 5 can also be V-shaped. The bottom of the groove is provided with a flexible sealing strip 7, and the edge of the box cover has a card platform. 6. The card table 6 can extend into the groove 5 to form a sealed structure. The L-shaped frame also enhances the strength of the meter box, and the flexible sealing strip plays a good sealing role. At the same time, the compressed flexible sealing strip deforms to both sides, filling the side gap between the box cover and the bottom of the box. It further plays a sealing effect, so it can effectively prevent dust and water, even if it is used in a harsh environment, it can also keep the meter box clean and dry.

The utility model is not limited to the above-mentioned embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the utility model.
