Abstract
The utility model discloses a four-bar linkage mechanism adjusting device with a major loop and a subsidiary loop which are connected with each other, and aims at solving the problem that installation space of an auxiliary contact is restricted by connection of the major loop and the subsidiary loop. The four-bar linkage mechanism adjusting device comprises a four-bar linkage mechanism, wherein the four-bar linkage mechanism comprises an auxiliary contact support piece, a lower supporting piece, a lower end supporting piece, an upper support piece, a lower support piece and an adjusting screw rod, two ends of the adjusting screw rod are respectively provided with the upper support piece and the lower support piece, the upper support piece is connected with the auxiliary contact support piece through an upper pin, the auxiliary contact support piece is connected with a rotary shaft of an auxiliary contact block, the lower support piece is connected with the lower supporting piece through a lower pin, and the lower supporting piece is connected with a rotary shaft of a contactor through the lower end supporting piece. The four-bar linkage mechanism adjusting device converts motions of the contactor through the four-bar linkage mechanism, and then transmits the motions to the subsidiary loop, and therefore available space of the auxiliary contact is greatly enlarged. Parameters of the auxiliary contact can be randomly adjusted through lengths of supporting pieces and can be guaranteed easily according to needs.
Description
Technical field
The utility model relates to the quadric chain adjusting device that a kind of A.C. contactor major loop is connected with subsidiary loop.
Background technology
Mostly the connected mode of domestic existing rotary type A.C. contactor major loop and subsidiary loop is in the major loop rotating shaft, to add an auxilliary top board that touches; Through top board subsidiary loop is directly passed in the action of major loop; The dynamic/static contact of subsidiary loop is connected and disjunction; So just limited the installing space of auxiliary contact, made auxiliary contact or can only be made of one the waste resource; Make modular, be difficult for guaranteeing because of the size of space little auxiliary contact is restricted parameter.
The utility model content
The purpose of the utility model provides the quadric chain adjusting device that a kind of major loop is connected with subsidiary loop, to have limited the problem of auxiliary contact installing space in solving major loop and subsidiary loop being connected.
The utility model technical scheme is following:
A kind of quadric chain adjusting device; Comprise quadric chain; Said quadric chain comprise the auxiliary contact supporter, down supporter, lower end supporter, on prop up part, prop up part and adjusting screw(rod) down; The two ends of said adjusting screw(rod) are equipped with a part and a following part, and a said part of going up links to each other with the auxiliary contact supporter through last pin, and said auxiliary contact supporter is connected with the rotating shaft of auxiliary contact group; A said following part links to each other with following supporter through downside pin, and said supporter down is connected with the contactor rotating shaft through said lower end supporter.
The utility model passes to subsidiary loop after through the movement conversion of quadric chain with contactor, has strengthened the free space of auxiliary contact greatly, makes auxiliary contact be easy to accomplish modular construction; The parameter of auxiliary contact can arbitrarily be adjusted through the length of supporter; Be easy to as required guarantee.Realized that effectively A.C. contactor often leaves many groups, normally closed, normally closed time-delay reaches the Synchronization Control of often driving the multiple auxiliary contact of time-delay.
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Description of drawings
Fig. 1 is a kind of structural representation of quadric chain adjusting device;
Fig. 2 is a kind of scheme of installation of quadric chain adjusting device.
Embodiment
A kind of quadric chain adjusting device; Comprise quadric chain 3; Quadric chain 3 comprise auxiliary contact supporter 2, down supporter 5, lower end supporter 12, on prop up part 91, prop up part 92 and adjusting screw(rod) 11 down; The two ends of adjusting screw(rod) 11 are equipped with part 91 and a following part 92, on prop up part 91 and pass through last pin 81 and link to each other with auxiliary contact supporter 2, auxiliary contact supporter 2 is connected with auxiliary contact group rotating shaft 7; Under prop up part 92 and link to each other with following supporter 5 through downside pin 82, following supporter 5 passes through lower end supporter 12 and is connected with contactor rotating shaft 6.Adjusting screw(rod) 11 two ends are provided with clamp nut 10.
The position in hole is to confirm according to the parameter of auxiliary contact on auxiliary contact supporter 2 and the following supporter 5.
Practical implementation process: moving iron core 4 and fixed core adhesive when contactor coil is charged; Driving contactor rotating shaft 6 rotates; The dynamic and static contact of contactor major loop is connected; Drive correspondingly down that supporter 5 turns an angle, through under prop up part 92, adjusting screw(rod) 11 passes motion to auxiliary contact supporter 2, drives connection and the disjunction that auxiliary contact group rotating shafts 7 realize auxiliary contacts 1 through auxiliary contact supporter 2 again.
