step two: after the cabinet door 2 rotates 180 degrees, the cabinet door 2 and the follower plate 20 will keep a static state;
step three: pressing the electric energy meter body 3 towards the follow-up plate 20 until the electric energy meter body 3 is in abutting connection with the clamping assembly, and continuing to apply force to the electric energy meter body 3 so as to enable the elastic rod to act and cooperate with the clamping assembly to fix the electric energy meter body 3 on the follow-up plate 20;
step four: after the electric energy meter body 3 is fixed, the cabinet door 2 is closed, so that the electric energy meter body 3 enters the shell 1 along with the follower plate 20, and the electric energy meter body 3 is installed.
To sum up, when cabinet door 2 is opened, when cabinet door 2 rotates 90, rotatory sleeve plate 5 rotates 45 under the effect of drive chain 4, no. one gear 11 is not meshed with No. one rack board 12 this moment, be threaded connection between lead screw 8 and the screw sleeve 9 simultaneously, make the connection stability between rotatory sleeve plate 5 and the expansion plate 6 higher, avoid when rotatory sleeve plate 5 rotates 45, the total length of rotatory sleeve plate 5 and expansion plate 6 changes, namely in this process, the radius of circular motion is constantly made to No. one pulley 7, simultaneously in this state, no. one pulley 7 slides in arc cell body 14, the circumference radius of arc cell body 14 is unanimous with the total length of rotatory sleeve plate 5 and expansion plate 6 in this state, and the centre of a circle of arc cell body 14 is concentric with the center of rotation of rotatory sleeve plate 5 in this state, make when No. one pulley 7 is circular motion, through this setting, can effectively avoid in the process that cabinet door 2 opens 90, because electric energy meter body 3 moves towards shell 1 outside, and interfere with cabinet door 2.
Further, when the cabinet door 2 continues to rotate for 90 degrees, the rotary sleeve plate 5 also continues to follow the rotation for 45 degrees, at this time, the first gear 11 is meshed with the first rack plate 12, and drives the screw rod 8 to rotate through the bevel gear group 10, so that the threaded sleeve 9 arranged on the screw rod 8 moves in the axial direction of the screw rod 8, so as to drive the telescopic plate 6 to move towards the outside of the rotary sleeve plate 5, namely, the radius of the circular motion of the first pulley 7 is gradually increased, and meanwhile, in the process of rotating the rotary sleeve plate 5 for 45 degrees, the first pulley 7 slides into the straight groove body 15, so that when the first pulley 7 performs the circular motion, the extension plate 13 can be ejected towards the outside of the shell 1, so that the electric energy meter body 3 moves towards the outside of the shell 1, until the cabinet door 2 rotates 180 degrees, and when the rotary sleeve plate 5 rotates for 90 degrees, the first pulley 7 is clamped with the groove 16, and in the state, the rotary sleeve plate 5, the telescopic plate 6 and the straight groove body 15 are in the vertical state, and under the action of the first spring 19, the cabinet door 2, the electric energy meter body 3 and the follower plate 20 are kept stationary, and when the cabinet door 2 is completely closed, the electric energy meter body 3 is completely removed, and when the electric energy meter body 3 is completely is opened, and the stability is completely is kept, and when the cabinet door 2 is completely closed, on the other side, and the stability is kept, when the cabinet door is completely is opened, and when the door is 20 is completely closed;
meanwhile, after the cabinet door 2 is opened, the electric energy meter body 3 is positioned outside the shell 1, so that the visual field is better when the electric energy meter body 3 is overhauled or meter reading is performed, the operation of personnel is facilitated, and the risk of electric shock caused by visual field loss of personnel is greatly reduced.
When cabinet door 2 opens, follow-up board 20 is stable after, can carry out more convenient installation and dismantlement to electric energy meter body 3, compare in current electric energy meter mounting means, avoided because operating in comparatively narrow and small space and causing the incident, avoid simultaneously because adopting bolted connection, the in-process that takes place to rock at shell 1 makes the connection between electric energy meter body 3 and the shell 1 take place not hard up condition.
For convenience of understanding, in order to describe the process of installing the electric energy meter body 3, first, in this state, the No. two springs 30 are in a compressed state, the No. two pulleys 35 are at one end of the sliding groove 34 away from the follower plate 20, the opening of the arc-shaped clamping member 31 faces the outside of the housing 1, when the electric energy meter body 3 is installed, the convex columns 24 provided at both sides of the electric energy meter body 3 are aligned with the guide grooves 25, and the electric energy meter body 3 is pushed toward the installation plate 21, since the inclined guide surfaces 26 are provided on the front end side walls of the guide grooves 25, a certain foolproof effect is provided in the process of the convex columns 24 entering the guide grooves 25, so that the convex columns 24 can be aligned with the guide grooves 25 better, and when the convex columns 24 enter the guide grooves 25, the convex columns 23 are engaged with the arc-shaped clamping members 31, when the second pulley 35 continuously acts on the electric energy meter body 3 to move, the second pulley 35 moves along the length direction of the sliding groove 34, the second spring 30 is further compressed, the sliding sleeve plate 27 moves towards the inside of the swinging sleeve plate 28, meanwhile, in the process, the second gear 32 generates transverse displacement, the second gear 32 rotates under the action of the second rack plate 33, the arc-shaped clamping piece 31 rotates, the sliding sleeve plate 27 and the swinging sleeve plate 28 are perpendicular to the sliding groove 34, the second spring 30 releases elastic potential energy, the electric energy meter body 3 is driven to move towards the inside of the shell 1 rapidly, the second spring 30 is still in a compressed state after the second pulley 35 moves to the stroke end of the sliding groove 34, the arc-shaped clamping piece 31 rotates 180 degrees, the convex column 24 moves to the end of the guide groove 25, and the electric energy meter body 3 is fixed on the follower plate 20.
Through the above-mentioned setting, realized the quick installation of electric energy meter body 3, replace traditional bolt and nut to connect simultaneously for fixed mode is simpler, and the operation is more convenient, and under No. two spring 30's effect, makes between electric energy meter body 3 and the follower 20 be elastic connection, thereby to when external wind-force etc. factor acts on shell 1 and makes its vibration, the connection between electric energy meter body 3 and the follower 20 can carry out certain buffering to the vibration, makes both can keep stable connected state.
