[0029] Reference example Figures 1 to 7, an electric energy metering box with an alarm function, comprising a box body 1, and a box door 2 hinged to the box body 1, the box body 1 is provided with a lock hole 11, and a conductive sheet 12 is provided in the lock hole 11, the box door 2 is provided with a fixed block 3, a handle 4, a lock body 5, a sliding switch 6, and a disconnection alarm 7, one end of the disconnection alarm 7 is electrically connected to the fixed block 3, and the other end is electrically connected to the conductive sheet 12, the handle 4 engages the fixed block 3, and the handle 4 is rotated to make the fixed block 3 move into the lock hole 11 and abut the conductive sheet 12, the box door 2 is provided with a first spring 9, and abuts the sliding switch 6, which is used to turn on the sliding switch 6; the sliding switch 6 is electrically connected to the disconnection alarm 7, and is used to control the start and stop of the disconnection alarm 7; the lock body 5 is rotated and abuts the handle 4, which is used to prevent the handle 4 from rotating;

[0030] It is worth mentioning that the box door 2 is provided with a guide block 21, and is located on both sides of the fixed block 3. The guide block 21 is provided with a guide groove 22. The box door 2 is provided with a limit block 23, and abuts against the end face of the fixed block 3. The box door 2 is provided with a top plate 24, and the top plate 24 is provided with a cylinder 25. The box door 2 is provided with a remote alarm module 8, and is electrically connected to the disconnection alarm 7. The guide groove 22 provides a guiding function for the fixed block 3, and the limit block 23 limits the retracted activity distance of the fixed block 3. The top plate 24 provides a support point for the first spring 9, and the cylinder 25 prevents the first spring 9 from detaching. The remote alarm module 8 reminds the monitoring personnel, and the maintenance personnel are sent to protect and maintain the electric energy metering box that has been violently disassembled;

[0031] It is worth mentioning that the fixed block 3 is provided with extension blocks 31 on both sides and is arranged in the guide groove 22. The extension block 31 is provided with a plurality of balls 32 and abuts the guide groove 22. The fixed block 3 is provided with a conductive rod 33. The outer wall of the conductive rod 33 is provided with an insulating layer 34. The side of the fixed block 3 is provided with a plurality of gear teeth 35. The extension block 31 is used in conjunction with the guide groove 22. The balls 32 improve the smoothness of the movement of the fixed block 3. The conductive rod 33 is used in conjunction with the second spring 14. The insulating layer 34 isolates the electrical connection between the conductive rod 33 and the fixed block 3, thereby reducing the contact resistance value of the conductive rod 33. The gear teeth 35 are used in conjunction with the gear 41.

[0032] It is worth mentioning that the conductive sheet 12 is provided with a countersunk hole 13, and the countersunk hole 13 is welded with a second spring 14. When the fixed block 3 abuts against the conductive sheet 12, the second spring 14 abuts against the conductive rod 33. The countersunk hole 13 provides a positioning function for welding the second spring 14. Due to tolerances in the manufacturing process or the handle 4 is touched by a non-staff member by mistake, the fixed block 3 retreats slightly. In order to compensate for the tolerance, the second spring 14 is electrically connected to the conductive rod 33 to ensure that the conductive sheet 12 and the conductive rod 33 are electrically connected stably.

[0033] It is worth mentioning that the handle 4 is provided with a gear 41 and meshes with the gear teeth 35. The handle 4 is provided with a fixing groove 42. The fixing block 3 is driven to move by the gear 41. The fixing groove 42 cooperates with the locking tongue 52.

[0034] It is worth mentioning that the lock body 5 is provided with a lock core 51, and the lock core 51 is provided with a rotatable lock tongue 52. When the lock core 51 is rotated, the lock tongue 52 rotates and abuts against the fixed groove 42. The lock core 51 is equipped with a matching key. Only when the lock core 51 is unlocked, the lock tongue 52 can rotate;

[0035] It is worth mentioning that the sliding switch 6 is provided with a slider 61, which is arranged on the track of the movement of the lock tongue 52. The slider 61 controls whether the sliding switch 6 is turned on or off, and the sliding switch 6 is closed by rotating the lock tongue 52;

[0036] It is worth mentioning that the first spring 9 is arranged on the outer wall of the cylinder 25 and abuts against the top plate 24 and the slider 61. The elastic force of the first spring 9 drives the slider 61 to move, thereby turning on the sliding switch 6 and starting and operating the disconnection alarm 7.

[0037] The use principle of the utility model is now described as follows:

[0038] In the initial state, the lock tongue 52 abuts against the slider 61, the sliding switch 6 is in a closed state, the disconnection alarm 7 is not powered, and the first spring 9 is in an energy storage state;

[0039] Rotate the handle 4 to rotate the gear 41 and drive the fixed block 3 to move in the direction of the lock hole 11 until the fixed block 3 abuts against the conductive sheet 12. After the second spring 14 abuts against the conductive rod 33, the handle 4 stops rotating when encountering great resistance. At this time, the conductive rod 33 and the conductive sheet 12 have been pre-electrically connected. Insert the key into the lock cylinder 51, turn the key, the lock cylinder 51 rotates, the lock tongue 52 moves with the lock cylinder 51, and the slider 61 loses the resistance of the lock tongue 52. The first spring 9 releases its elastic force and pushes the slider 61 to move, so that the sliding switch 6 is in the on state. The disconnection alarm 7 starts to operate until the lock tongue 52 abuts against the fixed groove 42, and the lock cylinder 51 stops rotating. At this time, the handle 4 is fixed.

[0040] When non-staff violently dismantles the box door 2 or the lock core 51, the electrical connection between the conductive rod 33 and the conductive sheet 12 is interrupted, and the circuit board built into the disconnection alarm 7 detects that the line is disconnected. The speaker inside the disconnection alarm 7 starts to sound an alarm. At the same time, the remote alarm module 8 is powered on and sends a signal to the monitoring personnel, indicating that maintenance personnel need to be sent to protect and maintain the violently dismantled electric energy metering box;

[0041] During normal maintenance, the key is inserted into the lock cylinder 51, and the key is turned. The lock cylinder 51 rotates, and the lock tongue 52 moves with the lock cylinder 51. The lock tongue 52 resets and pushes the slide to move toward the top plate 24, so that the sliding switch 6 is closed and the first spring 9 stores energy. The disconnection alarm 7 stops running. At this time, the electrical connection between the conductive rod 33 and the conductive sheet 12 is interrupted, and no whistle alarm sound is emitted.

[0042] The above design scheme can enable the product to have the advantages of alarm function, high safety and increased difficulty of disassembly.

[0043] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
