[0014] (III) Beneficial effects

[0015] The present invention provides an electric energy meter with an anti-theft function. It has the following beneficial effects:

[0016] (1) The electric energy meter with anti-theft function can complete the wiring by inserting the wire into the interior of the terminal. When the wire is directly pulled out from the interior of the terminal, the elastic force of the second spring sheet will push the extrusion block to move toward the interior of the terminal, and the top of the extrusion block will push the swing plate and the elastic expansion plate to move to the left.

When the wire is pulled out of the terminal, the extrusion block will not push the elastic expansion plate to move. The extrusion block can be pushed to move by the push rod and the connecting rod, thereby conveniently confining the wire inside the terminal.

[0017] (2) The electric energy meter with anti-theft function can transfer the heat on the device body to the sealing frame through the heat conductive sheet, so that the hollow frame can absorb the heat, thereby concentrating the heat at the bottom of the fan. The fan can discharge the heat from the device body through the exhaust frame, thereby improving the heat dissipation effect inside the device body.

[0018] (3) For the electric energy meter with anti-theft function, when the temperature inside the device body is about to reach the temperature of self-ignition, the expansion of gas inside the sealing frame will push the sealing plate and the fixing rod to move, and the fixing rod will drive the transmission rod and the locking rod to move. The locking rod will move away from the through hole on the L-shaped rod, so that the locking rod cannot limit the L-shaped rod and the elastic telescopic connecting rod. Under the action of the elastic force of the elastic telescopic connecting rod itself, the trapezoidal block will be pushed downward, and the trapezoidal block will push the wire to separate from the conductive block, so that the trapezoidal block will push the wire to move to the outside of the terminal, so that the wire is disconnected from the device body, so as to prevent the device body from continuing to work when it is powered on, and force the device body to stop working, thereby preventing the device body from spontaneously igniting.

[0019] (4) The electric energy meter with anti-theft function can push the control lever to move when reading the meter. When the control lever moves upward, it will push the swing block and the linkage rod to move. When the linkage rod contacts the horizontal plate, it will not be able to move upward, so that the control lever will push the swing block to rotate downward on the control lever. When the swing block rotates downward, it will push the filter plate to rotate. When the swing block contacts the protrusion, it will push the filter plate to shake. The shaking of the filter plate can improve the ventilation inside the device body and the heat dissipation inside the device body, thereby preventing foreign matter from adhering to the filter plates and affecting the ventilation effect of the filter plates. When the filter plates rotate, the scraper will move on the left side of the filter plates. By moving the scraper on the filter plate, foreign matter adhering to the right side of the filter plate can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A heat absorption device is arranged on the inner wall of the device body 1, and the heat absorption device comprises a sealing frame 51, and the sealing frame 51 is fixedly installed on the inner wall of the device body 1, and a heat conductive sheet 52 is fixedly installed on the surface of the sealing frame 51, and the bottom of the heat conductive sheet 52 is attached to the inner wall of the device body 1, and a hollow frame 53 is fixedly installed on the top of the sealing frame 51, and a fan 54 is fixedly installed on the top of the hollow frame 53, and the heat conductive sheet 52 can transfer the heat on the device body 1 to the sealing frame 51, so that the hollow frame 53 can absorb the heat, thereby concentrating the heat at the bottom of the fan 54, and the heat can be discharged from the device body 1 through the exhaust frame 3 through the fan 54, thereby improving the effect of heat dissipation inside the device body 1, and the top of the exhaust frame 3 is downward, which can prevent rain and dust from entering the inside of the device body 1.

[0034] The sealing frame 51 is provided with a high temperature protection device, which includes a sealing plate 55, which is slidably mounted on the inner wall of the sealing frame 51, and a No. 4 spring sheet is arranged between the sealing plate 55 and the sealing frame 51, a fixing rod 56 is fixedly mounted on the right side of the sealing plate 55, a transmission rod 57 is fixedly mounted on the right side of the fixing rod 56, and a positioning rod 58 is fixedly mounted on the bottom of the transmission rod 57, an elastic telescopic connecting rod 59 is fixedly sleeved on the bottom of the device body 1, an L-shaped rod 510 is fixedly mounted on the free end of the elastic telescopic connecting rod 59, a through hole is opened on the L-shaped rod 510, and a trapezoidal block 511 is fixedly mounted on the free end of the elastic telescopic connecting rod 59. When the temperature inside the device body 1 is about to reach the temperature of self-ignition, the sealing frame 5 The internal gas expansion will push the sealing plate 55 and the fixing rod 56 to move, and the fixing rod 56 will drive the transmission rod 57 and the locking rod 58 to move. The locking rod 58 will be away from the through hole on the L-shaped rod 510, so that the locking rod 58 cannot limit the L-shaped rod 510 and the elastic telescopic connecting rod 59. Under the action of the elastic force of the elastic telescopic connecting rod 59 itself, the trapezoidal block 511 will be pushed downward, and the trapezoidal block 511 will push the wire to separate from the conductive block 6, so that the trapezoidal block 511 will push the wire to move to the outside of the terminal 41, so that the wire is disconnected from the device body 1, so as to prevent the device body 1 from continuing to work when it is powered on, and forcibly stop the device body 1 from working, so as to prevent the device body 1 from spontaneous combustion.

[0035] A conductive block 6 is fixedly mounted on the inner wall of the terminal 41 , and a locking rod 58 is located inside the through hole. The locking rod 58 can limit the elastic telescopic connecting rod 59 and the L-shaped rod 510 .

[0036] The device body 1 is provided with an air intake dredging device, which includes a control rod 71, which is slidably sleeved on the device body 1, and an air inlet is provided on the device body 1. A filter plate 72 is rotatably installed on the inner wall of the air inlet, a swing block 73 is rotatably installed on the surface of the control rod 71, and a linkage rod 74 is fixedly installed on the surface of the swing block 73. A transverse plate 75 is fixedly installed on the inner wall of the device body 1, and a protrusion 710 is fixedly installed on the surface of the filter plate 72. When reading the meter, the control rod 71 can be pushed to move. When the control rod 71 moves upward, it will push the swing block 73 and the linkage rod 74 to move. When the linkage rod 74 contacts the transverse plate 75, it will not be able to enter. When the swing block 73 contacts the protrusion 710, the filter plate 72 is pushed to shake. The shaking of the filter plate 72 can improve the ventilation inside the device body 1, and the heat dissipation inside the device body 1 can be improved. The swinging of the filter plate 72 can prevent foreign matter from adhering to the filter plates 72 and affecting the ventilation effect of the filter plates 72. A volute spring is arranged between the filter plate 72 and the device body 1, a No. 3 spring is arranged between the linkage rod 74 and the cross plate 75, and a torsion spring is arranged between the swing block 73 and the control rod 71.

[0037] A guide plate 76 is fixedly installed on the inside of the air inlet, an elastic rod 77 is fixedly installed on the top of the guide plate 76, a bracket 78 is fixedly installed on the surface of the elastic rod 77, and a scraper 79 is fixedly installed on the end of the bracket 78 away from the elastic rod 77.

[0039] When a criminal steals the device body 1 and directly pulls the wire to separate from the terminal 41, the elastic force of the second spring sheet will push the extrusion block 45 to move inside the terminal 41. When the extrusion block 45 moves inside the terminal 41, it will contact the swing plate 44. The swing plate 44 is limited by the baffle 49. When the extrusion block 45 moves to the left, the swing plate 44 cannot rotate, so that the extrusion block 45 will push the swing plate 44 and the elastic expansion plate 43 to move to the left. When the elastic expansion plate 43 moves to the left, the notch on the elastic expansion plate 43 will squeeze the alarm device 42. The alarm device 42 will be squeezed and the alarm effect will be triggered. When the wire is normal, the control rod 46 is pushed upward.

[0040] The heat inside the device body 1 can be transferred to the sealing frame 51 through the heat conducting sheet 52, and the heat can be absorbed by the hollow frame 53. The heat around the hollow frame 53 can be discharged from the device body 1 through the exhaust frame 3 through the fan 54. When the device body 1 reaches the temperature of high-temperature self-ignition, the gas expansion inside the sealing frame 51 will push the sealing plate 55 to move to the outside of the sealing frame 51. When the sealing plate 55 moves, it will drive the fixing rod 56 to move. When the fixing rod 56 moves, it will drive the transmission rod 57 and the positioning rod 58 to move. When the positioning rod 58 moves, it will disengage from the through hole on the L-shaped rod 510, so that the positioning rod 58 will contact the limit of the L-shaped rod 510 and the elastic telescopic connecting rod 59. The elastic telescopic connecting rod 59 will push the trapezoidal block 511 to move downward under the action of its own elastic force. When the trapezoidal block 511 moves downward, it will push the wire to disengage from the conductive block 6 and the wire will move to the outside of the terminal 41.

[0041] When reading the meter of the device body 1, the control rod 71 can be pushed to move upward. When the control rod 71 moves upward, it will drive the swing block 73 and the linkage rod 74 to move upward. When the linkage rod 74 moves upward, it will contact the cross plate 75, so that the cross plate 75 can limit the upward movement of the linkage rod 74. When the control rod 71 continues to move upward, it will push the swing block 73 to rotate on the control rod 71. When the swing block 73 rotates, it will push the filter plate 72 to rotate toward the outside of the device body 1. When the swing block 73 contacts the protrusion 710 on the filter plate 72, the swing block 73 will push the filter plate 72 to vibrate. When the filter plate 72 rotates, it will push the scraper 79 to move on the right side of the filter plate 72.
