These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and accompanying drawings.

【Description of drawings】

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of embodiment one;

Fig. 3 is a schematic structural diagram of the second embodiment.

【Detailed ways】

The utility model provides an anti-stealing meter installation sleeve, which includes a bushing installed on the electric meter. The electric meter includes a shell and a wiring hole arranged on the shell. The bushing is connected to the wiring hole. The through hole is threaded with a wire, and the inner wall of the through hole is close to the outer wall of the wire. The sleeve is pressed tightly between the wire and the wiring hole, which can prevent the conductor from passing between the sleeve and the wiring hole, or from passing between the sleeve and the wire, thereby preventing others from short-circuiting and stealing electricity through the conductor.

The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present utility model.

Embodiment one:

Referring to Fig. 1 and Fig. 2, in the meter installation sleeve for preventing electricity theft shown, the casing 1 is connected to the electric meter, and the electric meter includes a housing 6, and the housing 6 is provided with wiring holes for connecting the wires for power supply. A sleeve 1 is inserted into the hole, and a through hole 2 for tightening the wire is arranged in the sleeve 1, and the sleeve can fill the gap between the wire and the wiring hole.

Among them, the material of sleeve 1 can use plastic expansion rods of different specifications, and its material is relatively hard, and the length can be trimmed according to the actual size, so as to adapt to filling the gaps of wiring holes with different apertures.

In the utility model, the outer circular surface of one end of the casing 1 is provided with a boss 11, and the other end of the casing 1 is connected with a limiter, and the side wall of the housing 6 is clamped between the boss 11 and the limiter. When connecting, the sleeve 1 passes through the wiring hole, and the boss 11 is against the outer surface of the housing 6 to prevent the conductor from passing between the sleeve and the wiring hole; The bit piece fixes the casing, which can prevent the casing from being forcibly pulled out, thus losing the anti-theft effect.
