Problems solved by technology

[0003] For example, the patent No. CN201810428742.2 is an easy-to-detach rainproof device for the meter box. By setting the rainproof shed to achieve the purpose of rainproof, the present invention can disassemble the rainproof shed from the meter box for easy use. Such technical solutions Quite a lot, although it can achieve a better rainproof and waterproof effect on the meter itself, once the meter itself is contaminated with rainwater, it is still easy for rainwater to enter the inside of the meter. Therefore, there has been a technical solution for improving the rainproof of the meter itself;
[0004] For example, the patent No. is CN201711400104.1 for a waterproof mechanical electric meter. The present invention is provided with a waterproof casing closely fitted to the electric wire in the threading hole of the electric wire, which can prevent water from entering the electric meter from the threading hole, increasing the The waterproof performance of the meter prolongs the service life of the meter, but this technical solution is only aimed at the waterproof improvement of the inlet pipe position, and most of the existing meters have set the wiring position at the bottom of the meter and covered it with a cover, so the waterproof of the meter itself It is still necessary to improve the connection between the cover plate and the watch case in order to achieve the optimal waterproof and rainproof purpose. Therefore, it is necessary to conduct further research on the basis of the existing waterproof mechanical ammeter to provide a new effective Electric meter with rainproof structure

Embodiment 1

[0024] See Figure 1-3 and Figure 5 In the embodiment of the present invention, the front surface of the electroslatase 1 is nested in the front side, and the back portion of the electric film shell 1 penetrates through the tube 101, and the tube 101 is adjacent to the tube 102, and the shell shell 1 and the cover A lock screw 3 is connected between the plates 2, and the cover plate 2 is provided with a projection edge 202 on the side of the film casing 1, and a groove is provided on both sides of the projection 202, and the bump edge 202 and the electric meter are provided. The housing 1 is embedded in the front side, and the cover 2 is fixed to the locking screw 3 connection is fixed to the push base 201, and the moving surface shell 1 is slid in the front side, and the electroslastic housing 1 is located on the left and right side of the pusher 106. The swing is provided with the sprinkle rod 105, and the hosted rod 105 is connected to the electric shaft and the electroslax 1 in...

Embodiment 2

[0029] See Figure 4 and Image 6 In this embodiment, the upper portion of the locking edge 103 is fixedly coupled to the waterproof air bag 1031, and the waterproof airbag 1031 is provided in a hemispherical shape, and the waterproof airbag 1031 is high greater than the projection 202 groove depth to the raised edge 202. A more well extrusion package effect is achieved, and the top of the waterproof airbag 1031 is provided with an inwardly recessed curved groove, and the surface of the curved groove is smooth, and the bump edge 202 recess is embedded in the groove 203, and the airbag strip 203 is also provided with a concave smooth curved groove in the side of the waterproof air bag 1031.

[0030] In this embodiment, when the locking edge 103 is gradually adjacent to the groove of the convex edge 202, the waterproof airbag 1031 is synchronized to complete the filling of the gap, further in the waterproof airbag 1031 and the airbag strip 203 is close to each other. After the match, ...

Abstract

The invention provides an electric meter with a rainproof structure, and belongs to the technical field of electrical equipment, a cover plate is nested in the front of an electric meter shell, a penetrating pipe penetrates through the back of the electric meter shell, a sealing rubber plug is nested in the top of the penetrating pipe, the electric meter shell and the cover plate are connected through a locking screw, and a protruding edge is arranged on the side, close to the electric meter shell, of the cover plate. A threaded base is fixedly connected to the joint of the interior of the cover plate and the locking screw. The electric meter with the rainproof structure is provided with the waterproof air bag and the air bag strip, after the locking edge strip gradually approaches the groove of the protruding edge, the waterproof air bag and the air bag strip can be attached, smooth arc-shaped grooves formed in the waterproof air bag and the air bag strip approach each other and extrude each other until the waterproof air bag and the air bag strip are completely attached, and air is exhausted. The two attached arc-shaped grooves are forced to be tightly attached due to the air pressure difference, so that external rainwater is not prone to penetrating through a gap between the two arc-shaped grooves, and a better rainwater-proof effect is achieved.

Description

Technical field [0001] The present invention relates to the technical field of electrical equipment, and more particularly to a meter. Background technique [0002] The electric meter is an indispensable device for statistics, and is very common in household and construction sites, but as electrical equipment typically disposed in an outdoor environment, the function of rainwater waterproof is essential, most of them are electric meter. Set inside the electric meter to achieve rainwater; [0003] For example, a patent number CN201810428742.2 is an easy-to-dismounting mesh box, which provides a rainy opening to reach the rainfall, and the present invention can be dismantled from the electric meter box, which is easy to use, and the like. Very much, although the electric table can achieve a better rainwater waterproof effect, once the electric meter itself is contaminated to the rain, it is easy to enter the inside of the electric meter, therefore, there is a technical solution for...
