The working principle and the using method of the invention are as follows: when a worker needs to inquire power consumption information, the door plate 4 is opened, at the moment, the two rotating shafts 3 rotate synchronously, the upper rotating shaft 3 pulls the pull rope 8 in the rotating process, the pull rope 8 drives the short rod 601 to rotate through the guiding of the guide shaft 7, at the moment, the first torsion spring 602 twists, the gear 603 rotates synchronously along with the short rod 601, the gear 603 drives the rack 902 and the wedge 903 to approach to the middle in the rotating process, the wedge 903 can extrude the sliding rod 1002 to move downwards in the moving process, the sliding rod 1002 is matched with the base 1001 and the lantern ring 1003 to extrude the second spring 1004, and meanwhile, the sliding rod 1002 drives the round rod 1101 to descend from the inside of the housing 5 to the front upper part of the ammeter body 2 through the boss 1102, so that the protection effect on the ammeter body 2 is achieved; in the rotation process of upper pivot 3, pawl 1403 is laminated with ratchet 15 all the time, and the contact between ratchet 15 and pawl 1403 can become to have the flank of tooth from the arc surface, can realize effective spacing to ratchet 15, upper pivot 3 and door plant 4 this moment, prevents that door plant 4 from being blown by wind to influence the inspection power consumption information and to ammeter body 2 overhaul, change.
When the door panel 4 is closed, the shift lever 1404 needs to be moved firstly to separate the pawl 1403 from the toothed surface of the ratchet wheel 15, then the door panel 4 is continuously closed, the shift lever 1404 can be released when the door panel 4 is to be closed, at this time, the pawl 1403 is reset to be in arc contact with the ratchet wheel 15, and then the door panel 4 can be completely closed; in the process, the first torsion spring 602 enables the short rod 601 and the gear 603 to rotate reversely, the rack 902 and the wedge 903 are separated towards two sides, and under the action of the second spring 1004, the sliding rod 1002 automatically ascends and drives the round rod 1101 to ascend through the boss 1102 and hide in the interior of the housing 5.
When the ammeter body 2 needs to be disassembled, overhauled and replaced, the door plate 4 is kept open, then the square rod moves the bottom of the round rod 1101, the square hole 1103 is aligned to be inserted upwards, the edge of the square rod extrudes the clamping block 1009 to enable the clamping block to move towards the corresponding placing groove 1006, at the moment, the boss 1102 and the round rod 1101 can be taken down, and then the ammeter body 2 can be loosened and taken down; after overhaul and change, aim at draw-in groove 1005 with boss 1102 and upwards hold up, the top of boss 1102 can extrude fixture block 1009 and make it move in the standing groove 1006 that corresponds to extrude third spring 1008 simultaneously, then again under the effect of baffle 1007 and third spring 1008, fixture block 1009 automatic re-sets and block in the corresponding card hole 1104, can realize effective spacing between slide bar 1002 and boss 1102 and the round bar 1101 again this moment.
After the electric meter body 2 is installed, electric wires to be connected penetrate through the threading holes 16 and are correspondingly connected; the first spring 18 arranged obliquely can generate an upward force on the electric wire by matching with the ferrule 19, and further, the electric wire falling off during installation and use can be reduced.
Through the matching of the structures such as the gear 603, the rack 902, the wedge 903, the slide bar 1002 and the like, the up-and-down movement of the round bar 1101 can be realized, the effective protection of the ammeter body 2 can be realized, the installation reliability of the ammeter body 2 is improved, and meanwhile, the electricity utilization inquiry and the maintenance and replacement of the ammeter body 2 cannot be influenced; through the matching of the structures such as the clamping groove 1005, the boss 1102, the clamping block 1009 and the clamping hole 1104, the round rod 1101 can be quickly installed and detached, and the maintenance and the replacement of the ammeter body 2 by workers are facilitated; through the matching of the structures such as the ratchet wheel 15, the pawl 1403, the shifting rod 1404 and the like, the effective limit on the ratchet wheel 15 and the door plate 4 in the rotating process can be realized, and the door plate 4 is prevented from moving randomly to influence the work of workers; through the matching of structures such as the chute 17, the first spring 18, the ferrule 19 and the like, the electric wire falling in the installation and use process can be avoided, the normal use of the electric meter body 2 is ensured, the whole practicability is higher, the anti-creeping device for the electric meter is organically linked with the electric meter with the dampproof and anti-theft functions, when the device does not leak electricity, the sliding rod is clamped in the limiting groove and is not triggered, when the shell leaks electricity due to the humidity or special conditions, the electromagnet is electrified due to the non-insulated connection of the anti-creeping device and the shell, the sliding rod is pushed outwards due to the magnetism same as the end part of the sliding rod, the limiting function disappears, the insulating curtain wound on the scroll downwards spreads out to comprise the whole shell, the device is effectively insulated to ensure that the device is not touched by mistake and is damaged when the device leaks electricity, a worker can know that the device leaks electricity when seeing that the insulating curtain is put down, and can take safety measures, has safe operability. .
