[0003] As an advanced, intelligent, and digital power grid front-end data acquisition component, power meters have been widely used. Traditionally, after a power meter is fixed, the connecting wires need to be installed in the reserved holes with screws or the connecting wires of the power meter need to be connected to the connecting wires of the equipment. This method of connecting power meters is cumbersome and inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-connect power meter to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an easy-to-connect power meter, including a meter, a fixing structure is provided above the meter, and an automatic connection structure is fixedly connected to the upper surface of the meter;

[0008] Preferably, a connecting block is fixedly connected to the outer surface of each sliding groove plate, and the bottom surface of each connecting block is fixedly connected to the upper surface of the instrument.

[0009] Preferably, a pressing ring is fixedly connected to the top of each sliding rod, and anti-slip strips arranged at equal intervals are fixedly connected to the upper surface of each pressing ring.

[0010] Preferably, each threaded rod has a fixedly connected screw ring at the end away from the sliding frame, and each screw ring has anti-slip openings arranged at equal intervals on its outer surface.

[0011] Preferably, a limiting plate is fixedly connected to the front side of each sliding groove plate, and the upper surface of each limiting plate is in contact with the bottom surface of the sliding frame.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] This invention, through the combination of a fixed structure and an automatic connection structure, enables convenient connection and use of instruments. Simultaneously, the rotation of the threaded rod allows it to move within a sliding frame. This movement of the threaded rod secures the connecting wire within the sliding frame. The sliding rod, moving within a fixed cylinder, drives the sliding frame downwards within a sliding groove. This sliding movement of the frame moves the secured connecting wire into a conductive frame. A battery provides power to the brake motor, which, controlled by a controller, rotates in both directions. This rotation drives the threaded shaft, which, along with its own thread, slides within the sliding groove along with the brake motor. The rotation of the inner and outer rings of the rotating bearing further drives the threaded shaft to move the pressing block within the sliding groove towards the conductive frame. The contact between the pressing block and the conductive frame secures the connecting wire within the conductive frame, further enhancing the convenience of connecting instruments.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-6 An easy-to-connect power meter includes a meter 1, a fixing structure 2 is provided above the meter 1, and an automatic connection structure 3 is fixedly connected to the upper surface of the meter 1.

[0029] The fixed structure 2 includes two sets of sliding groove plates 201. Each sliding groove plate 201 has a sliding frame 204 slidably connected inside. Each sliding groove plate 201 has a fixed cylinder 202 fixedly connected to its inner wall. Each fixed cylinder 202 has a sliding rod 203 slidably connected to its back. The bottom end of each sliding rod 203 is fixedly connected to the upper surface of the sliding frame 204. Each sliding frame 204 has a threaded rod 205 threadedly connected to its inner wall. By setting the sliding frame 204, the connecting wire can be placed inside. At the same time, through the rotation of the threaded rod 205 and its own thread, the connecting wire can be fixed inside the sliding frame 204. Then, by sliding the sliding rod 203 inside the fixed cylinder 202, the sliding frame 204 can be driven to slide inside the sliding groove plate 201. By using the sliding of the sliding frame 204, the fixed connecting wire can be moved to a designated position. Furthermore, during connection, the connecting wire can be fixed first to prepare for connection with the instrument 1.

[0030] Each sliding groove plate 201 has a connecting block 12 fixedly connected to its outer surface. The bottom surface of each connecting block 12 is fixedly connected to the upper surface of the instrument 1. Through the connecting block 12, it can be fixed on the sliding groove plate 201 and fixed to the instrument 1, so that the sliding groove plate 201 can be fixed on the instrument 1 for use.

[0031] Each sliding rod 203 is fixedly connected to a pressing ring 7 at its top end. Each pressing ring 7 is fixedly connected to an anti-slip strip 10 arranged at equal intervals on its upper surface. The pressing ring 7 allows the operator to press the sliding rod 203 easily when sliding it, while the anti-slip strip 10 prevents slipping when pressing.

[0032] Each threaded rod 205 is fixedly connected to a rotating ring 14 at the end away from the sliding frame 204. Each rotating ring 14 has anti-slip holes 15 arranged at equal intervals on its outer surface. The rotating ring 14 facilitates the operation of the threaded rod 205 for the operator, and the anti-slip holes 15 provide an anti-slip effect.

[0033] Each sliding groove plate 201 is fixedly connected to a limiting plate 11 on its front side. The upper surface of each limiting plate 11 is in contact with the bottom surface of the sliding frame 204. The limiting plate 11 can be fixed on the sliding groove plate 201 and can block the sliding frame 204 when it moves, thus achieving the effect of limiting the sliding frame 204.

[0034] The specific implementation method of this embodiment is as follows: First, the connecting wire is placed inside the sliding frame 204. At the same time, the threaded rod 205 is turned by the turning ring 14 in conjunction with the anti-slip port 15. Through the rotation of the threaded rod 205 and its own thread, it moves to one side. At the same time, when the threaded rod 205 moves, it squeezes the connecting wire into the sliding frame 204. After squeezing, the sliding rod 203 slides downward in the fixed cylinder 202 by pressing the pressing ring 7. At the same time, it drives the sliding frame 204 to slide downward, and the sliding frame 204 drives the connecting wire to move downward. When the sliding frame 204 contacts the limiting plate 11, the pressing stops.

[0035] Example 2

[0036] Please see Figure 1-6 The automatic connection structure 3 includes a fixed housing 301. Two sets of sliding brackets 305 are fixedly connected to the inner top and bottom walls of the fixed housing 301. A threaded shaft 306 is threadedly connected to the inner wall of each sliding bracket 305. Two sets of conductive brackets 309 are fixedly connected to the inner bottom wall of the fixed housing 301. A rotating bearing 308 is fixedly connected to one end of each threaded shaft 306 near the conductive bracket 309. A pressing block 304 and a brake motor 307 are slidably connected inside each sliding bracket 305. A controller 302 is located above the fixed housing 301, and a battery 303 is located on the front of the fixed housing 301. The battery 303 provides power to the controller 302 and the brake motor. 307 provides power and, using controller 302, controls the forward and reverse rotation of the brake motor 307. The rotation of the brake motor 307 drives the threaded shaft 306 to rotate within the sliding groove 305. When the sliding groove 305 rotates, the rotating bearing 308 follows suit, allowing the threaded shaft 306 to use its own thread to drive the brake motor 307 and the pressing block 304 to slide within the sliding groove 305. Through the sliding of the pressing block 304, it can contact the conductive frame 309, thereby pressing and fixing the connecting wire within the conductive frame 309. With the conductive frame 309 and the pressing block 304 working together, the instrument 1 can be easily connected and used.

[0037] An insulating ring 9 is fixedly connected to the back of the outer ring of each rotating bearing 308. The back of each insulating ring 9 is fixedly connected to the front of the extrusion block 304. Through the insulating ring 9, the extrusion block 304 and the rotating bearing 308 can be connected and fixed. At the same time, the insulating ring 9 can play an insulating role by utilizing its own insulating material.

[0038] Each brake motor 307 has a protective shell 16 fixedly connected to its outer surface. Each protective shell 16 has a heat dissipation vent 13 on its front side. The protective shell 16 can protect the brake motor 307, and the heat dissipation vent 13 can dissipate heat from the brake motor 307, thereby extending the service life of the brake motor 307.

[0039] The bottom surface of the controller 302 is fixedly connected to the support base 8, and the bottom surface of the support base 8 is fixedly connected to the upper surface of the fixed shell 301. The controller 302 can be fixed on the fixed shell 301 through the support base 8. The controller 302 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0040] A battery box 4 is fixedly connected to the upper surface of the instrument 1. The inner wall of the battery box 4 is in contact with the outer surface of the battery 303. The battery box 4 can be fixed on the instrument 1 and the battery 303 can be placed therein, so that the battery 303 can be used stably.

[0041] The upper surface of the battery box 4 is connected to a protective door 6. Two ventilation openings 5 ​​are provided on the upper surface of the protective door 6. The protective door 6 can be used to open or close the battery box 4, and the ventilation openings 5 ​​can be used to ventilate the inside of the battery box 4.

[0042] The specific implementation method of this embodiment is as follows: First, the storage battery 303 is connected to the power supply. When in use, the protective door 6 is opened, and the storage battery 303 is installed in the battery box 4. The controller 302 and the brake motor 307 are connected to the storage battery 303 through wires. After the connection is completed, the controller 302 starts the brake motor 307 to rotate through the wires. The brake motor 307 drives the threaded shaft 306 to rotate in the sliding groove frame 305. At the same time, the inner and outer rings of the rotating bearing 308 follow the rotation. When the threaded shaft 306 rotates, it drives the brake motor 307 and the pressing block 304 to move towards the position of the conductive frame 309 through the thread. When the pressing block 304 moves into the conductive frame 309, the brake motor 307 is continuously started to rotate, so that the pressing block 304 presses and fixes the connecting wire in the conductive frame 309, thereby enabling the instrument 1 to automatically connect.

[0043] Example 3

[0044] Please see Figure 1-6The specific implementation method of this embodiment is as follows: First, the connecting wire is placed inside the sliding frame 204. At the same time, the threaded rod 205 is turned by the turning ring 14 in conjunction with the anti-slip port 15. Through the rotation of the threaded rod 205 and its own thread, it moves to one side. At the same time, when the threaded rod 205 moves, it squeezes the connecting wire into the sliding frame 204. After squeezing, the pressing ring 7 is pressed to make the sliding rod 203 slide downward in the fixed cylinder 202, which in turn drives the sliding frame 204 to slide downward. The sliding frame 204 also drives the connecting wire to move downward. When the sliding frame 204 contacts the limiting plate 11, the connecting wire moves into the conductive frame 309. Then, the pressing is stopped, and the battery 303 is connected to the power supply. The protective door 6 is opened, and the connecting wire is then... The battery 303 is installed in the battery box 4, and the controller 302 and the brake motor 307 are connected to the battery 303 via wires. After the connection is completed, the controller 302 starts the brake motor 307 to rotate via the wires. The brake motor 307 drives the threaded shaft 306 to rotate in the sliding groove frame 305. At the same time, the inner and outer rings of the rotating bearing 308 follow the rotation. When the threaded shaft 306 rotates, it drives the brake motor 307 and the pressing block 304 to move towards the position of the conductive frame 309 through the thread. When the pressing block 304 moves into the conductive frame 309, the brake motor 307 continues to rotate, so that the pressing block 304 presses and fixes the connecting wire in the conductive frame 309, thereby enabling the instrument 1 to connect automatically.
