Specifically, the metering box 18 includes a power supply end electric energy metering module and a plurality of user end electric energy metering modules. The power supply end electric energy metering module is used for the electric energy metering of each user end electric energy metering module, and the user end electric energy metering module is used for the electric energy metering of the corresponding user end. A first cavity is opened on one side of the box door 2, and a driving motor 3 is arranged inside the first cavity.

On the front of the box door 2, a keyhole 17 is also provided for inserting the key. On the back of the box door 2, a maintenance door 19 for maintaining the locking mechanism 14 is provided.

[0025] In summary, when the key is inserted into the keyhole 17 and directly rotated clockwise, the locking mechanism 14 will lock the rotating shaft 5 so that it cannot rotate, and then the box door 2 cannot be opened; when the key is inserted into the keyhole 17 and first rotated counterclockwise and then clockwise, the locking mechanism 14 will unlock the rotating shaft 5, and the rotating shaft 5 can rotate to open the box door 2.

[0026] Embodiment 2: On the basis of Embodiment 1, combined with Figure 3 , specifically, the pushing mechanism 6 includes a first threaded rod 61 fixedly connected to the right end of the rotating shaft 5.

[0027] Sliding blocks 64 for horizontally limiting the first threaded block 62 are fixedly connected to the upper and lower surfaces of the first threaded block 62, and the sliding blocks 64 slide horizontally in the first cavity.

[0028] In the above structure, when the rotating shaft 5 rotates, it drives the first threaded rod 61 to rotate, and then drives the first threaded block 62 and the first guide rod 63 to slide horizontally, and then drives the lock block 7 to slide horizontally in the first cavity.

[0029] Combined with Figure 4 , specifically, the transmission mechanism 10 includes a connecting rack 101 fixedly connected to the right side of the extrusion block 9. A connecting plate 114 is fixedly connected to the right end of the connecting rack 101. A spring 115 is fixedly connected to the right side of the connecting plate 114. The right end of the spring 115 is fixedly connected to the right inner wall of the second cavity.

[0030] In the above structure, when the lock block 7 moves to the right and enters the second cavity to achieve preliminary locking. Secondly, the lock block 7 will drive the extrusion block 9 to move further to the right, drive the connecting rack 101 and the connecting plate 114 to move to the right, and compress the spring 115 to provide a reverse restoring force.

[0031] On the upper side of the connecting rack 101, there is an engaged connection with a connecting gear 102. The connecting gear 102 is further connected to a rotating positioning shaft 111 through a transmission assembly. Specifically, the transmission assembly includes a first connecting shaft 103 fixedly connected to the middle of the connecting gear 102. On the outer wall of the first connecting shaft 103, there is fixedly connected a first driving wheel 104. The outer wall of the first driving wheel 104 is drivingly connected to a first conveyor belt 105. On the upper side of the first conveyor belt 105, there is a driving connection with a first driven wheel 106. In the middle of the first driven wheel 106, there is fixedly connected a second driving wheel 108 through a second connecting shaft 107. The outer wall of the second driving wheel 108 is drivingly connected to a second conveyor belt 109. On the left side of the second conveyor belt 109, there is a driving connection with a second driven wheel 110. The positioning shaft 111 is fixedly connected to the middle of the second driven wheel 110. At the front end of the positioning shaft 111, there is fixedly connected a first bevel gear 112. At the bottom of the first bevel gear 112, there is an engaged connection with a second bevel gear 113. The rotating rod 11 is fixedly connected to the middle of the second bevel gear 113.

[0032] In the above structure, as the connecting rack 101 moves to the right, it will drive the connecting gear 102 to rotate, drive the first driving wheel 104 to rotate. Under the transmission of the first conveyor belt 105, it drives the first driven wheel 106 to rotate, and drives the second driving wheel 108 to rotate. Under the transmission of the second conveyor belt 109, it drives the second driven wheel 110 to rotate. Under the connection of the first bevel gear 112 and the second bevel gear 113, it drives the rotating rod 11 to rotate.

[0033] Secondly, the moving mechanism 12 includes a second threaded rod 121 fixedly connected to the bottom end of the rotating rod 11. On the outer wall of the second threaded rod 121, there is a longitudinally moving second threaded block 122 threadedly connected. At the bottom of the second threaded block 122, there is fixedly connected a second guide rod 123. The bottom of the second guide rod 123 is fixedly connected to the insertion rod 13.

[0034] In summary, under the rotation of the rotating rod 11, it drives the second threaded rod 121 to rotate, thereby driving the second threaded block 122 and the second guide rod 123 to slide longitudinally, thereby driving the insertion rod 13 to move downward and engage with the locking groove 8, realizing further locking and improving the anti-theft effect.

[0035] Embodiment Three: On the basis of Embodiment Two, combined with Figure 5 and Figure 6, Specifically, the locking mechanism 14 includes a third bevel gear 141 fixedly connected to the outer wall of the rotating shaft 5 and a lock rod 145 inserted into the front of the box door 2. A fourth bevel gear 142 is meshed and connected to one side of the third bevel gear 141. A docking shaft 143 is fixedly connected to the middle of the fourth bevel gear 142. The other end of the docking shaft 143 is fixedly connected to a turntable 144. The inner end of the lock rod 145 is fixedly connected to a connecting rod 146. A torsion spring 147 is arranged at the bottom of the connecting rod 146. The other end of the torsion spring 147 is connected to the turntable 144. The upper end of the connecting rod 146 is fixedly connected to a spring rod 148. A card slot 149 is arranged at the end of the spring rod 148. An unpenetrated first jack 150 is arranged on the left side of the surface of the turntable 144. A second jack 151 penetrates through the right side of the surface of the turntable 144. An elastic ball 152 adapted to the card slot 149 is arranged on the inner wall of the second jack 151.

[0036] The locking mechanism 14 further includes an emergency battery 155 and an electric telescopic rod 153. The emergency battery 155 independently supplies power to the electric telescopic rod 153. Even if the external power supply is cut off by a thief, the emergency battery 155 can still work. A stop block 154 is fixedly connected to the extending end of the electric telescopic rod 153 to play a blocking role. The stop block 154 is spaced 1-2 cm from the turntable 144.

[0037] The locking mechanism 14 further includes a fixing rod 156. A bearing 157 is fixedly connected to the upper end of the fixing rod 156. The bearing 157 is sleeved on the outer wall of the docking shaft 143 for limiting and fixing.

[0038] In summary, when the key is inserted into the keyhole 17, the key will squeeze the lock rod 145 to move inward. When the key is rotated counterclockwise, it will drive the lock rod 145 to rotate counterclockwise, causing the connecting rod 146 and the spring rod 148 to rotate counterclockwise around the lock rod 145, and the end of the spring rod 148 is closely attached to the turntable 144. When it rotates to the first jack 150, the end of the spring rod 148 will be squeezed into the first jack 150. At this time, when the key is rotated clockwise, the lock rod 145 and the turntable 144 can be driven to rotate clockwise together. The turntable 144 drives the fourth bevel gear 142 to rotate clockwise, and then drives the third bevel gear 141 to rotate, finally realizing the rotation of the rotating shaft 5 to open the box door 2. This operation method is rehearsed for the staff in advance; When the key is inserted into the keyhole 17, the key will squeeze the lock rod 145 to move inward. When the key is rotated clockwise, it will drive the lock rod 145 to rotate clockwise, causing the connecting rod 146 and the spring rod 148 to rotate clockwise around the lock rod 145. The end of the spring rod 148 is in close contact with the turntable 144. When it rotates to the second jack 151, the end of the spring rod 148 will extend and penetrate into the second jack 151. At the same time, the elastic ball 152 will snap into the card slot 149, making the spring rod 148 unable to rebound, and the stopper 154 hinders the continued rotation of the spring rod 148. At this time, it will be impossible to drive the turntable 144 to rotate. Whether the key is rotated clockwise or counterclockwise, the rotation of the rotating shaft 5 cannot be achieved, making the box door 2 unable to be opened.

[0039] Embodiment 4: The embodiment of the present invention provides a usage method of the intelligent anti-theft power metering device in Embodiment 3, including the following steps: Step 1: Under the condition of power on (the driving motor 3 and the electromagnetic clutch 4 work): Normal: The staff presses the fingerprint on the fingerprint recognition area 16. After the fingerprint recognition module in the fingerprint recognition area 16 recognizes the fingerprint of the staff, it transmits information to the control switch through the information processor, thereby realizing the control of the driving motor 3. The driving motor 3 works, and the lock block 7 and the lock slot 8 are snapped into the box body 1. During the movement, the insertion rod 13 moves downward and is snapped into the lock slot 8, and the box door 2 is locked for the second time; similarly, when the driving motor 3 works in the reverse direction, the lock block 7 and the lock slot 8 return, the insertion rod 13 moves upward and disengages from the lock slot 8, and the box door 2 is opened; Abnormal: When a thief maliciously recognizes the fingerprint or uses the key to unlock, the camera 15 monitors in real time and transmits information to the remote end; Step 2: Under the condition of power off (the driving motor 3 and the electromagnetic clutch 4 fail): Normal: The staff inserts the key into the keyhole 17 and rotates it counterclockwise first. When hearing a "click" sound, it means that the end of the spring rod 148 is squeezed into the first jack 150, and then rotates it clockwise to open the box door 2; Abnormal: When a thief illegally obtains the key, the key will be inserted into the keyhole 17 and the key will be directly rotated clockwise subconsciously, causing the end of the spring rod 148 to extend and penetrate into the second jack 151. At the same time, the elastic ball 152 will snap into the card slot 149, making the spring rod 148 unable to rebound, and the stopper 154 hinders the continued rotation of the spring rod 148. At this time, it will be impossible to drive the turntable 144 to rotate. Whether it is rotated clockwise or counterclockwise or the key is pulled out, the rotation of the rotating shaft 5 cannot be achieved, making the box door 2 unable to be opened; Step 3: Emergency treatment: Subsequently, the staff urgently controlled the operation of the electric telescopic rod 153 to drive the stopper 154 to retract, that is, to cancel the obstruction to the spring rod 148. Then, by continuing to turn the key, the box door 2 can be opened again; After the box door 2 is opened, since the elastic ball 152 is still locked in the card slot 149, that is, the spring rod 148 cannot return to its original position. The staff can open the inspection door 19 and push it out. At this time, the spring rod 148 returns to its original position under the action of the torsion spring 147.
