[0033] Embodiment 1

[0034] Reference Figure 1-Figure 3 , an electricity monitoring instrument with anti-theft protection function, comprising:

[0035] Protection box 1;

[0036] The mounting plate 2 is mounted on the inner wall of the protection box 1. The electrical monitoring instrument body 3 is placed on the top of the mounting plate 2. A rotating block 10 is rotatably connected to one side of the protection box 1. A door panel is rotatably connected to the protection box 1. A wiring hole 11 is opened at the bottom of the protection box 1.

[0037] The clamping mechanism is mounted on the mounting plate 2 and is transmission-connected to the rotating block 10;

[0038] The alarm mechanism is installed between the electrical monitoring instrument body 3 and the protection box 1 . A controller 19 is installed on the inner wall of one side of the protection box 1 . The controller 19 is connected to the alarm mechanism. An alarm 20 is installed on the top of the protection box 1 .

[0039] In this embodiment, the clamping mechanism includes two wedge-shaped clamping plates 4, which are slidably installed on the top of the mounting plate 2, and the two wedge-shaped clamping plates 4 cooperate with the electrical monitoring instrument body 3. Two sliding holes 5 are provided on the mounting plate 2, and a sliding rod 7 is fixedly installed on the inner wall of the sliding hole 5. A connecting block 6 is slidably connected to the sliding rod 7, and the connecting block 6 is fixedly connected to the corresponding wedge-shaped clamping plates 4. A bidirectional screw 8 is fixedly installed on the rotating block 10, and two symmetrically arranged moving blocks 9 are threadedly connected to the bidirectional screw 8. The moving block 9 is fixedly connected to the corresponding connecting block 6. The two wedge-shaped clamping plates 4 are close to each other and can clamp and press the electrical monitoring instrument body 3. The sliding rod 7 is slidably connected to the connecting block 6, so that the activity trajectory of the wedge-shaped clamping plates 4 can be limited by the connecting block 6. The rotating bidirectional screw 8 is threadedly connected to the two moving blocks 9, so that the two moving blocks 9 can be driven to approach each other, and then the wedge-shaped clamping plates 4 are driven to move through the connecting block 6.

[0040] In this embodiment, the alarm mechanism includes a mounting seat 12, which is mounted on one side of the electrical monitoring instrument body 3. A push rod 14 is slidably connected to one side of the mounting seat 12. One end of the push rod 14 passes through the protective box 1 and is slidably connected to the protective box 1. A groove 13 is provided on one side of the mounting seat 12. A mounting rod 15 is fixedly mounted on the inner wall of one side of the groove 13. A contact switch 16 is installed at one end of the mounting rod 15. An electric metal block 17 is fixedly mounted on one end of the push rod 14. The electric metal block 17 and the contact switch 16 are in contact with each other. A top spring 18 is fixedly mounted on the inner wall of one side of the groove 13. One end of the top spring 18 is fixedly connected to the electric metal block 17. Limiting grooves are provided on the top inner wall and the bottom inner wall of the groove 13. The sliding connection in the limiting groove A limit block is connected, which is fixedly connected to the push rod 14. The push rod 14 passes through the protective box 1 and is slidably connected to the protective box 1, so that the electric monitoring instrument body 3 can be connected and contacted with the installation wall. When the electric monitoring instrument body 3 and the protective box 1 move in position, it is detected by the push rod 14. The contact setting of the electric metal block 17 and the contact switch 16 makes the alarm 20 in a stable state. When the electric metal block 17 is separated from the contact switch 16, the switching state of the contact switch 16 is triggered, so that the alarm 20 sounds an alarm. The setting of the top spring 18 enables the push rod 14 to move when the push object is lost. The sliding connection between the limit block and the limit groove can facilitate the limiting of the push rod 14.

[0041] Working principle: during operation, the electrical monitoring instrument body 3 is placed on the mounting plate 2, and the rotating block 10 is rotated. The rotating block 10 drives the bidirectional screw 8 to rotate. The rotating bidirectional screw 8 is connected to the two moving blocks 9 through a threaded connection, thereby driving the two moving blocks 9 to approach each other, and then driving the wedge-shaped clamping plate 4 to move through the connecting block 6, so that the electrical monitoring instrument body 3 can be clamped, pressed and fixed. The contact setting of the electric metal block 17 and the contact switch 16 makes the alarm 20 in a stable state. When the protective box 1 and the electrical monitoring instrument body 3 are displaced, the electric metal block 17 is separated from the contact switch 16, which triggers the switching state of the contact switch 16, thereby causing the alarm 20 to sound an alarm. The setting of the top spring 18 enables the push rod 14 to push the push rod 14 to move when the push object is lost. The sliding connection between the limit block and the limit groove can facilitate the limiting of the push rod 14.

[0043] The difference between this embodiment and the first embodiment is that a signal transmitter 21 is installed on the top inner wall of the protective box 1. The setting of the signal transmitter 21 can remotely transmit the switch state generated by the contact switch 16, which is convenient for remote monitoring. All structures in this application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.

[0044] The above is only a preferred specific implementation of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of this embodiment within the technical scope disclosed in this embodiment, which should be covered by the protection scope of this embodiment.
