In the process of household electricity use, the electric meter is used to calculate the amount of electricity used by the user. The electric meter box is a carrier for centralizing the household electricity meters.

[0003] According to a transparent electric meter box with a flame-retardant structure disclosed (publication number: CN217692278U), in the above application, the fire extinguishing component provided can extinguish the open flame generated inside the box, avoiding the existing electric meter box that does not have a flame-retardant structure. That is, when smoke or open flame is generated inside the box, the smoke alarm sounds an alarm and transmits the alarm signal to the controller through the connecting line. The controller controls the solenoid valve to open and release the dry powder inside the dry powder tank, thereby achieving the effect of extinguishing open flames and improving the safety of the electric meter box.

[0004] The above-mentioned meter box releases dry powder through a dry powder tank to extinguish the open flame inside the box, but the meter box installs the dry powder tank inside the box through a clamp, which causes the dry powder tank to release dry powder only in a fixed direction.

The sound of the bell can be used to warn the surrounding people to prevent strangers from approaching the box, and can also remind relevant staff so that they can take corresponding measures in time.

[0017] 3. The transparent electric meter box with a flame-retardant structure moves downward through the sealing plate, and at the same time, the limit plate can release the limit on the limit rod by cooperating with the inclined block and the push rod. At this time, the elasticity of the torsion spring can drive the rotating rod to rotate and reset. When the rotating rod is rotated and reset, it will drive the protective cover to cover the control panel. The protective cover can be used to protect the control panel to prevent the open flame inside the box from causing damage to the control panel; and in the process of rotating and resetting, the rotating rod can use the sliding rod and the sliding groove on the side wall of the protective cover to push the T-shaped rod, so that the T-shaped rod drives the cross rod to push the hollow rod. At this time, the hollow rod will drive the cover plate to rotate on the inner wall of the box door, and the cover plate will expose the back of the control panel while rotating, so that the surface of the control panel can contact with the external air, thereby achieving the effect of heat dissipation of the control panel, preventing the open fire inside the box from causing high temperature of the control panel.

The gear 79 reciprocates while the rack 710 meshing with it can be used to make the gear 79 rotate reciprocatingly. The reciprocating rotation of the gear 79 drives the driving rod 78 to reciprocate at the bottom of the latch 75. The reciprocating rotation of the driving rod 78 drives the reed 711 to rotate synchronously. At this time, the reed 711 drives the steel ball 712 to repeatedly strike the bell 77, causing the bell 77 to emit a rapid sound. The sound emitted by the bell 77 can be used to warn the surrounding personnel and prevent strangers from approaching the box body 1.

[0041] When the sealing plate 72 moves downward, the inclined surface block 88 will be driven to move downward synchronously. When the inclined surface block 88 contacts the push rod 87 during the downward movement, the push rod 87 will be squeezed, so that the push rod 87 pushes the limit plate 85, which will cause the limit plate 85 to slide on the inner wall of the box door 2 and stretch the limit spring 86. In the process of sliding, the limit plate 85 will gradually move away from the limit rod 84. When the limit plate 85 is completely separated from the limit rod 84, the limit plate 85 will release the limit on the limit rod 84. At this time, the elasticity of the torsion spring 82 can push the limit rod 84, so that the limit rod 84 drives the rotating rod 81 to rotate and reset on the inner wall of the box door 2. When the rotating rod 81 rotates and resets, it will drive the protective cover 83 to cover the control panel 5. The rotating rod 81 rotates and resets During the positioning process, the protective cover 83 will drive the sliding rod 811 to move against the inner wall of the sliding groove 810, and the sliding rod 811 will push the T-shaped rod 89, so that the T-shaped rod 89 gradually slides out of the box body 1 on the inner wall of the box door 2, and the T-shaped rod 89 will drive the cross bar 814 to fit the inner wall of the hollow rod 813 during the sliding process, and the cross bar 814 will push the hollow rod 813, so that the hollow rod 813 drives the cover plate 812 to rotate on the inner wall of the box door 2, and as the cover plate 812 gradually rotates, the back side of the control panel 5 can be exposed, so that the surface of the control panel 5 can be in contact with the external air, thereby achieving the effect of heat dissipation of the control panel 5, preventing the open fire inside the box body 1 from causing the control panel 5 to reach high temperature.
