Description

Metering box Technical Field The utility model relates to the technical field of shells of electromechanical devices, in particular to a metering box. Background The ammeter box is a box body for internally installing an ammeter, and can play a certain role in isolating and protecting the ammeter. The ammeter case is provided with the upper cover that can open whole box generally on the box, still is provided with the qianmen that can open and shut relatively the upper cover on the upper cover, and the qianmen can be convenient for the staff to inspect ammeter incasement portion. The utility model discloses a little door waterproofing mechanism of table case as disclosed in the chinese patent document of the bulletin number CN209927911U of the authority, this little door waterproofing mechanism of table case is provided with the upper cover on the table case, rotates through the pivot and is equipped with little door on the upper cover, and little door is equipped with the clamp bar towards the one side of upper cover, covers and is equipped with the recess correspondingly to be equipped with the sealing washer in the recess, so when little door is closed relative to the upper cover, the clamp bar can press in the recess and support tightly with the sealing washer, thereby reinforcing the leakproofness and the waterproof dustproof effect of table case. Simultaneously be provided with square hole on the dodge gate, be equipped with the lamellar lock nose that corresponds with square hole on the upper cover, the lock nose can pass square hole when the relative upper cover of dodge gate is closed, still is equipped with a lockhole that is used for setting up the padlock on the lock nose, so can add the padlock on the lock nose after the dodge gate is closed, can avoid irrelevant personnel to open the dodge gate to improve the security and the anti-theft electric capacity of table case. The locking assembly is further arranged on the watch box and comprises a copper insert which is arranged on the upper cover and provided with a threaded hole, and a knob which is used for being in threaded connection with the copper insert, a small hole which is used for the knob to pass through is formed in the small door, the knob is closed and then passes through a through hole of the small door to be in threaded connection with the threaded hole on the copper insert, the knob cap at the upper end of the knob gradually compresses the small door in the rotating process of the knob, and a pressing rib on the inner side surface of the small door is forced to press a sealing ring on the upper cover, so that the effect of pressing and sealing is achieved, and automatic loosening of the small door due to tension of the sealing ring is avoided.
