Description

Technical Field

[0001] This utility model belongs to the field of power instrument technology, and more specifically, it relates to a smart power instrument. Background Technology

[0002] The intelligent power meter is an intelligent device for medium and low voltage systems. It integrates data acquisition and control functions, and has the functions of power parameter measurement and power metering. It provides a communication interface to connect with a computer monitoring system and supports RS485 interface, MODBUS communication protocol or multiple protocols.

[0003] When installing a smart power meter on a cabinet, the meter must first be placed into a pre-drilled mounting hole in the cabinet. Then, it is installed using plastic clips that match the slots on both sides of the smart power meter. Since the plastic clips and the smart power meter are usually separate components before installation, omitting any clip can easily lead to installation failure, thus limiting its usability. Therefore, this paper researches and improves upon the existing structure and its shortcomings to provide a smart power meter with greater practical value. Utility Model Content

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a smart power meter, including a main body 1. Connecting grooves 2 are provided on both sides of one end of the main body 1. Connecting blocks 3 are slidably connected to the inner sides of both sets of connecting grooves 2. Connecting seats 4 are fixedly installed on one side of each connecting block 3. A light rod 5 is slidably connected to one side of the connecting seat 4. One end of the light rod 5 passes through the connecting seat 4 and is fixedly connected to a pressure plate 6. Receiving grooves 14 are provided on the main body 1 corresponding to the connecting seats 4 and the pressure plate 6. A pad frame 15 is slidably connected to the outer side of the main body 1, and one side of the pressure plate 6 abuts against one side of the pad frame 15.

[0023] The inner side of the connecting seat 4 is rotatably connected to a threaded cylinder 9, and the inner side of the threaded cylinder 9 is threadedly connected to a screw 10. One end of the screw 10 passes through the connecting seat 4 and is fixedly installed with a fixing block 11. The outer side of the fixing block 11 is rotatably connected to a limiting seat 12. One side of the limiting seat 12 is fixedly connected to one side of the pressure plate 6 by fasteners, which can realize the flexible movement of the pressure plate 6.

[0024] The connecting seat 4 is threadedly connected to a worm 7 on its inner side, and a worm wheel 8 is coaxially fixedly connected to the outer side of the threaded cylinder 9. The worm 7 and the worm wheel 8 are meshed and connected, which can drive the threaded cylinder 9 to rotate flexibly.

[0025] The connecting seat 4 has a cover plate 13 fixedly connected to one side by fasteners, which allows for easy disassembly and assembly of the cover plate 13. The cover plate 13 has a through hole corresponding to the worm gear 7. One end of the worm gear 7 is located in the through hole and has an internal hexagonal hole, which can be easily connected to an existing hexagonal wrench to enable flexible rotation of the worm gear 7.

[0026] A limiting rod is fixedly installed on one side of the connecting block 3, and a limiting groove is provided on one side of the connecting groove 2 to slide in connection with the limiting rod, so as to prevent the connecting block 3 from falling out of the connecting groove 2.

[0027] A spring is installed inside the connecting groove 2. The two ends of the spring abut against one side of the connecting block 3 and one side of the inner wall of the connecting groove 2, respectively, so that the connecting block 3 can be automatically ejected after being squeezed into the connecting groove 2.

[0028] A rubber pad 16 is fixedly adhered to the outside of the main body 1 to prevent external dust and water from entering the cabinet through the connection between the main body 1 and the cabinet.

[0029] The working principle of this embodiment is as follows: When the main body 1 needs to be installed, first press the connecting block 3 to move the connecting block 3 and the connecting seat 4 into the connecting groove 2 and the receiving groove 14, and remove the pad frame 15 from the main body 1. Then, pass one end of the main body 1 through the mounting hole on the cabinet. When the connecting block 3 passes through the mounting hole, the mounting hole will squeeze one side of the inclined surface of the connecting block 3, causing it to move into the connecting groove 2. The connecting seat 4 and the pressure plate 6 move into the receiving groove 14. After passing through the mounting hole, the spring will drive the connecting block 3 and the connecting seat 4 to pop out automatically. Then, the pad frame 15 is placed on the outside of the main body 1. At this time, the pad frame 15 is located between the inner wall of the cabinet and the connecting seat 4. Then, use a hex wrench to rotate the worm gear 7 to drive the worm wheel 8 and the threaded cylinder 9 to rotate. The threaded cylinder 9 drives the screw 10 to move. The screw 10 drives the pressure plate 6 to move and push the pad frame 15, so that one side of the pad frame 15 is pressed against the cabinet wall. At this time, one side of the main body 1 is pressed against the outer wall of the cabinet, completing the installation of the main body 1.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
