Description

Technical Field

[0001] The utility model relates to the technical field of meter boxes, in particular to a meter box with a dustproof function. Background Art

[0002] The meter box is a box used to install power measuring equipment such as energy meters, current transformers, voltage transformers, etc. The meter box is usually made of metal materials and has functions such as protection, sealing, and anti-theft to ensure the safe and accurate operation of power measuring equipment.

[0003] The patent with publication number CN220209664U discloses a meter box with dustproof function, which includes a dustproof component, and the dustproof component includes a box body, a box door, a mounting plate, a heat dissipation hole, a connecting shell, a slot, a mounting frame, a fixed plate, a support plate, a slide bar, a pressure plate, a spring, a pull plate, a rotating shaft, a card plate, a fixed magnetic block, a movable magnetic block and a dustproof cloth. The device pulls the pull plate outward and rotates the rotating shaft so that the rotating shaft drives the card plate to move between the pull plate and the support plate to clamp the pull plate. At this time, the spring is in a compressed state, and the dustproof cloth is placed between the pressure plate and the fixed plate. The rotating shaft is rotated so that the card plate no longer blocks the pull plate. The spring stretches and pushes the pressure plate to press the dustproof cloth to fix the dustproof cloth. However, the device has The heat dissipation holes are blocked by dustproof cloth to intercept the dust entering from the heat dissipation holes, and then the dustproof cloth is removed and replaced by using the cooperation of the mounting frame, the pull plate and other structures. Although this dust-proof measure for the meter box effectively intercepts the dust with the dustproof cloth, as the interception time increases, more and more dust will be accumulated on the dustproof cloth, and the heat dissipation holes are easily blocked by the dustproof cloth that slowly accumulates dust, thereby making the heat dissipation of the meter box worse and worse. Even if the dustproof cloth is easy to replace, it is difficult to ensure the heat dissipation effect of the meter box before replacement. For this reason, a meter box with dustproof function is proposed to solve the problem that the heat dissipation holes of the existing meter box are easily blocked by dust, resulting in reduced heat dissipation effect.
