[0002] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. A single-phase electronic fee-controlled smart electric energy meter is a type of electric energy meter. It is designed and manufactured using today's most advanced electric energy meter-specific integrated circuits, microprocessors, non-volatile memory that permanently stores information, wide-temperature liquid crystal displays, and other technologies and SMT processes.

[0003] When existing electric energy meters are installed and used, they are generally fixedly connected with the mounting base by means of a guide rail. Since the buckle of this connection method is a plastic component, during the process of installation or disassembly, the electric energy meter body can only be pushed hard to separate or engage the buckle. The buckle is very likely to break during operation, which makes it impossible to install and use. Another part of the electric energy meter is installed by bolt fixing. The entire installation and disassembly process requires the use of corresponding tools, which is time-consuming and labor-intensive. In summary, the existing electric energy meters are inconvenient to install and disassemble. Therefore, in view of the above situation, an electric energy meter that is easy to install is proposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figure 1-4 This application is further described in detail.

[0027] The present application embodiment discloses an electric energy meter that is easy to install. Figure 1 , Figure 2 , Figure 3 and Figure 4 , an electric energy meter that is easy to install, includes an assembly plate 1 and an electric energy meter body 3.

[0028] A pair of positioning plates 101 are disposed on the surface of the assembly plate 1 , and a pair of cylinders 2 are disposed on the positioning plates 101 .

[0029] The cylinder 2 has a circular groove 201 , the inner wall of which is provided with a pair of limiting cavities 202 , and the cylinder 2 has a pair of sockets 203 , which are respectively connected to the limiting cavities 202 . A spring 204 is arranged in the circular groove 201 , and a resisting plate 205 is fixedly connected to the spring 204 .

[0030] A pair of connecting parts 4 are provided at the top and bottom of the electric energy meter body 3. The connecting parts 4 include a base 401 fixedly connected to the surface of the electric energy meter body 3. A telescopic rod 402 is threadedly engaged on the base 401. A circular plate 403 is provided at the end of the telescopic rod 402 away from the base 401. A connecting rod 404 is provided on the top of the circular plate 403. The connecting rod 404 is inserted into the circular groove 201 through the socket 203 and cooperates with the limiting cavity 202.

[0031] Reference Figure 1 The outer surface of the assembly plate 1 is provided with two pairs of arc plates, each of which has a threaded hole.

[0032] Furthermore, when using the device, the assembly plate 1 can be fixed on the electric meter box by firstly passing bolts through the threaded holes on the arc-shaped plate.

[0033] Reference Figure 1 A guide block 102 is provided on the outer surface of the assembly plate 1, and a groove adapted to the guide block 102 is opened on the back of the electric energy meter body 3, and the guide block 102 is slidably matched with the groove.

[0034] Furthermore, the sliding cooperation between the guide block 102 and the groove realizes the preliminary installation of the electric energy meter body 3 , and provides convenience for the subsequent positioning of the electric energy meter body 3 .

[0035] Reference Figure 2 The top of the base 401 has a thread groove, and the outer wall of the telescopic rod 402 has a thread structure that matches the thread groove.

[0036] Furthermore, the threaded connection between the telescopic rod 402 and the base 401 allows the telescopic rod 402 to be detached from the electric energy meter body 3, thereby having the benefit of being reused.

[0037] Furthermore, the base 401 is in a cylindrical structure, and the telescopic rod 402 is composed of a first rod body and a second rod body. The first rod body is gap-fitted with the second rod body, and the second rod body is connected to the circular plate 403 .

[0038] Reference Figure 2 and Figure 3 , the radius of the circular plate 403 is the same as the radius of the circular groove 201.

[0039] Furthermore, the radius of the circular plate 403 is the same as the radius of the circular groove 201 , thereby ensuring that the circular plate 403 smoothly enters the circular groove 201 to complete the subsequent positioning operation.

[0040] Reference Figure 3 and Figure 4 A pair of limiting cavities 202 are symmetrically arranged in the circular groove 201.

[0041] Furthermore, a pair of limiting cavities 202 are symmetrically arranged in the circular groove 201, thereby ensuring that after the connecting rod 404 rotates 90 degrees, both ends of the connecting rod 404 rotate into the corresponding limiting cavities 202 to complete the fixation of the connecting rod 404.

[0042] Reference Figure 3 The shape of the abutment plate 205 is circular, and the radius of the abutment plate 205 matches the radius of the circular groove 201 .

[0043] Furthermore, when the abutment plate 205 is not squeezed, the abutment plate 205 blocks the limiting cavity 202 . After being squeezed by the connecting rod 404 , the limiting cavity 202 is exposed and the abutment plate 205 cooperates with the rotated connecting rod 404 .

[0044] Reference Figure 2 and Figure 3 , the distance between the upper surface and the lower surface of the limiting cavity 202 is the same as the distance between the upper surface and the lower surface of the connecting rod 404.

[0045] Furthermore, it can be ensured that the rotating connecting rod 404 cooperates with the limiting cavity 202 .

[0046] Working principle: When installing the electric energy meter body 3, first fix the assembly plate 1, align the groove on the back of the electric energy meter body 3 with the guide block 102 and slide it onto the guide block 102, then move the movable end of the telescopic rod 402 upward to insert the connecting rod 404 into the socket 203, and rotate the telescopic rod 402 after squeezing the contact plate 205 by the connecting rod 404, so that the connecting rod 404 can be rotated into the limiting cavity 202, thereby realizing the positioning of the connecting rod 404, that is, realizing the positioning of the telescopic rod 402, thereby fixing and installing the electric energy meter body 3. Compared with the traditional installation method, the device is more convenient for the installation of the electric energy meter body 3, has higher installation efficiency, and can avoid damage to related accessories during installation.

[0047] In addition, after the connecting rod 404 rotates into the limiting cavity 202 to position the telescopic rod 402, since the spring 204 is in a compressed state at this time, the resistance plate 205 has a downward force on the connecting rod 404, which can further limit the connecting rod 404 and prevent the connecting rod 404 from accidentally rotating and slipping off the socket 203, thereby ensuring the stability of the device when in use.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
