Referring to fig. 1, an electric energy metering box comprises a box body 1, a box door 2 and a transparent observation window 3 arranged on the box door 2, wherein connecting pieces 4 are arranged at four corners of the box door 2, and the connecting pieces 4 are used for being matched with expansion bolts, so that the electric energy metering box is fixed on a wall.

Referring to fig. 2, 3 and 4, the connecting piece 4 in this embodiment is a swingable movable structure, one end of the connecting piece 4 is rotatably connected to the case 1, the other end of the connecting sheet 4 is provided with a first waist-shaped hole 5, the first waist-shaped hole 5 is used for the expansion bolt to penetrate, a locking piece 7 is arranged in front of the connecting piece 4, the locking piece 7 is fixedly connected with the box body 1, a locking groove 8 is arranged on the locking piece 7 along the vertical direction, a second waist-shaped hole 6 is also arranged in the middle of the connecting sheet 4, the locking groove 8 is positioned in a fan-shaped area formed by the second waist-shaped hole 6 along with the swinging of the connecting sheet 4, a movable locking block 10 is arranged in the locking groove 8, regular tooth grooves 9 are symmetrically arranged on two side walls of the locking groove 8, convex teeth 12 are symmetrically arranged on two side walls of the locking block 10, the shape and size of the convex teeth 12 are matched with the tooth grooves 9, and threaded holes 11 are formed in the locking block 10. The locking piece 7 is further provided with a locking bolt 13, the bolt body of the locking bolt 13 comprises a threaded section and a smooth section, the locking bolt 13 penetrates through the threaded hole 11, the threaded section of the locking bolt 13 is in threaded fit with the threaded hole 11, the smooth section of the locking bolt 13 is inserted into the second kidney-shaped hole 6, the front end of the locking bolt 13 is connected with a screwing cap 14, and the surface of the screwing cap 14 is provided with anti-skidding threads. The diameter of the smooth section of the locking bolt 13 is slightly smaller than the width of the second kidney-shaped hole 6, so that the locking bolt 13 can move in the second kidney-shaped hole 6, and the contact gap between the locking bolt 13 and the connecting piece 4 is small. The connecting piece 4 is limited from swinging by inserting the locking bolt 13 into the second kidney-shaped hole 6, and when the locking block 10 is clamped into the locking groove 8, the connecting piece 4 is locked.

Referring to fig. 5, a concave and fan-shaped containing groove 16 is formed in the back of the four corners of the box body 1, a shaft hole 17 is formed in one end of the connecting piece 4 connected with the box body 1, a fixing shaft 18 penetrates through the shaft hole 17, the fixing shaft 18 is fixedly connected with the box body 1, the connecting piece 4 can swing around the fixing shaft 18, the swing range of the connecting piece 4 is the fan-shaped coverage range of the containing groove 16, a first limiting piece 19 is further connected to the end portion of the fixing shaft 18, and the first limiting piece 19 can prevent the connecting piece 4 from being separated from the box body 1. Further, a second stopper piece 20 is connected to the rear end of the lock bolt 13. In this embodiment, the range of the swing angle of the connecting piece 4 is ± 30 degrees (the swing angle of the connecting piece 4 is O degrees when it is in a horizontal state).

The installation steps of the electric energy metering box are as follows: the worker drills holes at the marked positions on the wall, then drives expansion bolts into the four holes, then screws the locking bolts to increase the distance between the locking block 10 and the second limiting piece 20, then pulls the locking bolt 13 forwards to separate the locking block 10 from the locking groove 8, at the moment, the connection is unlocked and can swing freely, the box body 1 is attached to the wall after the four connecting pieces 4 are all unlocked, then each connecting piece 4 is adjusted, the head end parts of the four collision bolts exposed out of the wall respectively penetrate through the first waist-shaped holes 5 on the four connecting pieces 4, nuts are mounted at the ends of the expansion bolts, at the moment, the nuts are not screwed tightly, and therefore the position of the box body 1 can be finely adjusted. The box body 1 is finely adjusted while the locking bolt 13 is screwed down, so that each locking block 10 can accurately enter each locking groove 8, and the locking bolt 13 is completely screwed down after the locking block 10 completely enters each locking groove 8 (when the locking block 10 and the second limiting piece 20 clamp the connecting piece 4, the locking bolt 13 cannot be continuously rotated, and at the moment, the locking bolt 13 is completely screwed down), so that each connecting piece 4 can be locked and fixed. Then, the nuts of the respective expansion bolts are tightened, thereby firmly fixing the cabinet 1 to the wall.

This electric energy metering box is because connection piece 4 is adjustable movable structure, can adjust the angle of connection piece 4 according to expansion bolts's position in the installation, and first waist shape hole 5 all is the scope that can normally squeeze into expansion bolts along with the swept region of connection piece 4 swing, therefore this electric energy metering box still can normally install when expansion bolts has great positioning error, can reduce drilling and squeeze into expansion bolts's the degree of difficulty, is applicable to various installation conditions.

In this embodiment, an elastic pad 15 is further provided on the surface of the locking piece 10 that contacts the connecting piece 4. When the locking bolt 13 is tightened, the locking piece 10 and the second stopper piece 20 clamp the connecting piece 4, and the elastic pad 15 is clamped. When the locking block 10 is slightly loosened, the locking block 10 is tensioned by the elastic force generated by the elastic pad 15, so that the locking block 10 is stably kept in the locking groove 8, the connecting sheet 4 is prevented from being slightly loosened, and the mounting reliability is improved.

The elastic pad 15 in this embodiment is a rubber pad, and the rubber pad is adhered and fixed to the locking block 10. And the rubber pad is made of porous foaming rubber material, and a plurality of micropores are formed in the rubber pad. Compared with a solid rubber pad, the porous rubber pad has better elastic deformation capacity and is not easy to age and lose elasticity.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
