Detailed Description
The clearance type plug of the electric meter box comprises a driving pin 6, a sliding rod 7, a copper plug 4, a guide sleeve 3 and a return spring 5 (see the attached figures 1 and 2 in the specification).
One end of a flip cover 1 of the electric meter box plug connector is eccentrically provided with an extrusion rotating shaft 2; the electric meter box plug connector is provided with a guide sleeve 3; the lower part of the guide sleeve 3 is crosswise provided with a copper plug 4 (see the description attached to fig. 1 and 2).
The copper plug 4 is made of a conductive material, is of a step-shaped cylindrical structure, and the diameter of the copper plug close to the root part is larger than that of the copper plug at the top part; the top part of the bracket is in a conical structure;
a plurality of lap joint elastic sheets 8 are arranged at one cylindrical end; the lap joint elastic sheets 8 are positioned on the same circumferential surface; a control bulge 9 is arranged inside each lapping elastic sheet 8; the control bulge 9 is of an arc structure; the inner part of each lapping elastic sheet 8 is provided with a control bulge 9 which is positioned on the same circumferential surface (refer to the attached figures 2 and 4 of the specification). The purpose of thus providing the copper plug 4 is: when the electric energy meter works, the control protrusion 9 extrudes the lapping elastic sheet 8, the lapping elastic sheet 8 expands outwards and opens, and after the control protrusion 9 loses support, the lapping elastic sheet 8 can be folded mutually, so that the purpose of facilitating the insertion and the extraction of the electric energy meter into and from the copper plug 4 is achieved.
A driving pin 6 is mounted in the guide sleeve 3 through a return spring 5 (see the description attached to fig. 1 and 2). The upper end of the driving pin 6 is provided with a limit flange 14 (see the description and the attached figure 3); a return spring 5 is arranged between the driving pin 6 below the limiting flange 14 and the copper plug 4 (see the attached figures 1 and 2 in the specification). Under the effect of 5 elasticity of reset spring, driving pin 6 has the trend of upward movement all the time, so can ensure that driving pin 6 can remain conflict with extrusion pivot 2 all the time and be connected.
The pressing rotating shaft 2 on the flip cover 1 of the electric meter box is eccentrically arranged (refer to the attached figures 1 and 2 in the specification). When the flip cover 1 is in an open state, the plane of the extrusion rotating shaft 2 is in contact with the transmission pin 6, and the transmission pin 6 is in an upper limit position; when flip 1 is in the closed condition, the convex surface of extrusion pivot 2 contacts with driving pin 6, and extrusion pivot 2 passes through convex surface extrusion driving pin 6, makes driving pin 6 move down to the lower limit position.
The lower end of the driving pin 6 is provided with a wedge-shaped plug 11 (see the description and the attached figure 3); the wedge-shaped plug 11 extends through the copper plug 4 into the interior thereof.
The copper plug 4 is internally provided with a sliding rod 7 in a sliding way (see the description attached to figures 1 and 2); the sliding rod 7 can slide back and forth in the copper plug 4 when being stressed.
A control inclined hole 10 is arranged in one end of the sliding rod 7. The driving pin 6 is connected with the control inclined hole 10 of the sliding rod piece 7 in a sliding plug-in mode through a wedge plug 11 (see the attached figure 3 in the specification). The structure of the control inclined hole 10 is consistent with that of the wedge-shaped plug 11 (see the description and the attached figure 3); the purpose of thus arranging the driving pin 6 and the sliding bar 7 is: so that in the process of the transmission pin 6 moving down, the transmission pin 6 can extrude the control inclined hole 10 through the left inclined surface, so that the sliding rod piece 7 can move backwards (namely leftwards), and in the process of the transmission pin 6 moving up, the transmission pin 6 can extrude the control inclined hole 10 through the right inclined surface, so that the sliding rod piece 7 can slide rightwards in the copper plug 4.
The other end of the sliding rod piece 7 is provided with an extrusion flange 12; the inner side of the extrusion flange 12 is provided with an extrusion slope 13 (see the description and the attached figure 3); the glide rod 7 is connected to the control protrusion 9 via the press ramp 13 (see the description of fig. 4). The purpose of the extrusion flange 12 being so arranged is: so that during the operation, the sliding rod 7 moves backwards (leftwards), the extrusion flange 12 can extrude the lapping elastic sheet 8 of the copper plug 4 outwards through the extrusion slope 13 under the cooperation of the control bulge 9, and the lapping elastic sheet 8 expands outwards. When the sliding rod 7 moves forwards (rightwards), the control protrusion 9 of the lapping elastic sheet 8 gradually loses the support of the extrusion flange 12, and the lapping elastic sheets 8 can be mutually folded under the action of self elastic force in the process.
This clearance formula plug during operation of ammeter case, when the flip 1 of ammeter case plug connector was in the closed condition, the convex surface and the contact of transmission round pin 6 of extrusion pivot 2, extrusion pivot 2 passes through convex surface extrusion transmission round pin 6, makes transmission round pin 6 be in the lower limit position (see description attached figure 2). At this time, the sliding rod 7 is at the leftmost position, and the sliding rod 7 provides support for the overlapping elastic sheet 8 of the copper plug 4 through the extrusion flange 12 and the control protrusion 9, so that the overlapping elastic sheet 8 expands outwards and is connected with the electric energy meter (see the attached figure 2 in the specification).
When the turning cover 1 of the electric meter box is opened, the plane of the extrusion rotating shaft 2 is contacted with the transmission pin 6; at this time, the driving pin 6 is moved upward to the upper limit position by the elastic force of the return spring 5. During the upward movement of the driving pin 6, the driving pin 6 can press the control inclined hole 10 through the right inclined surface, so that the sliding rod 7 can slide to the right inside the copper plug 4. In the process that the sliding rod piece 7 slides rightwards, the control protrusion 9 of the overlapping elastic sheet 8 gradually loses the support of the extrusion flange 12, and in the process, the overlapping elastic sheets 8 can be mutually folded under the action of self elastic force (see the attached figure 1 of the specification). When the flip cover 1 is opened, the copper plug 4 can be automatically contracted, so that the aim of conveniently pulling out the electric energy meter by people is fulfilled.
When the turning cover 1 is closed after the electric energy meter is reassembled, the convex surface of the extrusion rotating shaft 2 extrudes the transmission pin 6 to enable the transmission pin to overcome the elastic force of the return spring 5 and move downwards. During the downward movement of the driving pin 6, the driving pin 6 can press the control inclined hole 10 through the left inclined surface, so that the sliding rod 7 can slide leftwards in the copper plug 4. In the process that the sliding rod piece 7 moves leftwards, the extrusion flange 12 can extrude the lapping elastic sheet 8 of the copper plug 4 outwards through the extrusion slope 13 under the matching of the control bulge 9, so that the lapping elastic sheet 8 expands outwards and is connected with the electric energy meter again.
This clearance formula plug of ammeter case, compact structure, design benefit, when the flip 1 of ammeter case plug connector is opened, copper plug 4 will contract automatically, and copper plug 4 is automatic to be expanded when the flip 1 of ammeter case plug connector is closed, has solved current ammeter case plug connector from this and has deposited the problem that the electric energy meter inserts and extract hard loaded down with trivial details, is particularly suitable for people's user demand.
