Invention content

The utility model is mainly solving the technical problems that provide a kind of multistation positioning of universal circuit breaker drawer seat Structure.

Technical solution is used by the utility model solves its technical problem：A kind of universal circuit breaker drawer seat Multistation location structure, including main body, wherein main body include planker, push plate, fixed plate, main shaft, instruction axis, tripper with And resetting shaft, main shaft, instruction axis and resetting shaft are to be arranged in parallel, and three both passes through push plate and fixed plate, main shaft and Resetting shaft is arranged with planker in linkage, and main shaft and resetting shaft are arranged with push plate in linkage, and resetting shaft is equipped with locking member, locking Part is set there are three groove, and instruction axis is equipped with protrusion, and protrusion radially engages with groove, and protrusion switches in different grooves to be realized Indicate the instruction of axis different conditions；Tripper is used to release the fixation of protrusion and groove.

When main shaft rotates clockwise, drive planker sliding, planker sliding that instruction axis can be driven to be rotated counterclockwise, this When protrusion mutually block with groove, main shaft can not move, and be now placed in discrete state；It presses resetting shaft to unlock, continues rotation master Axis is now placed in trystate at this point, protrusion is mutually blocked with second groove；It presses resetting shaft to unlock, continues rotation master Axis is now placed in connection status at this point, protrusion is mutually blocked with third groove；Conversely, when spindle axis counterclockwise rotation and phase State switching is realized with principle.

Wherein, further include surface frame, tripper is located in surface frame, and tripper includes unlock piece and torsional spring, unlock piece Including ontology, ontology is equipped with lug boss and extension, and torsional spring is set on ontology；Resetting shaft is equipped with and is adapted to lug boss Bayonet, bayonet and raised portion fits locking resetting shaft is axially moved, and instruction axis is equipped with the convex block being adapted to extension, when convex When rising with groove cooperation, convex block pushes extension so that bayonet and lug boss latch-release, resetting shaft are axially movable.

Tripper is located at the setting in surface frame so that tripper is easier to replace；Pass through bayonet elder generation and lug boss card Close so that resetting shaft can not move axially, and when lug boss and groove coordinate, convex block pushes extension so that the other end it is convex The portion of rising is detached with bayonet, at this point, resetting shaft can be arbitrarily axially moved, realizes the unlock of protrusion and groove；Torsional spring, which plays, quickly to be divided From effect.

Wherein, it is equipped with indicator at the top of instruction axis, indicator is embedded in surface frame.

Setting of the indicator in surface frame so that operator in operation, is not easy to influence the normal of indicator Instruction, prevents from indicating abnormal.

Wherein, unlock piece is separately positioned with main shaft, and ontology is equipped with through-hole, and it is that main shaft cooperation is real that rocking bar, which may pass through through-hole, Now link.

Unlock piece is with main shaft using separately positioned so that replacement is more convenient, and ontology is equipped with through-hole, and rocking bar can easily be worn It crosses and coordinates with main shaft, through-hole also acts as certain guide-localization effect, prevents rocking bar from coordinating deviation.

Wherein, locking member is equipped with fastening part, interconnecting piece and tight lock part, and fastening part is connect with tight lock part by interconnecting piece, Fastening part is fixed with resetting shaft, and tight lock part is semicircle, and groove is located on tight lock part.

Locking member uses such setting so that protrusion more closely, prevents maloperation with groove cooperation.

Wherein, locking member is integrally formed with resetting shaft.

It is arranged using being integrally formed so that process more convenient, cost reduction, reduce manual assembly time.

Wherein, interconnecting piece is equipped with via, and main shaft passes through via.

Wherein, spring is equipped between fixed plate and push plate.

Pass through the setting of spring so that reset is more convenient, without by going to operate manually.

Wherein, further include bearing, bearing is set on main shaft, and is arranged in rotation with fixed plate.

The use of bearing so that main axis is protected, and rotation is more smooth.

Wherein, resetting shaft is equipped with position limiting structure, and position limiting structure includes hook portion and blocking portion, and fixed plate is located at blocking Between portion and hook portion, resetting shaft moves forward, and blocking portion offsets with fixed plate, and resetting shaft moves backward, hook portion and fixation Plate offsets.

The setting of blocking portion prevents resetting shaft is excessive from stretching in main body, overall structure is caused to damage；Hook portion is set It sets, prevents restoring force of the resetting shaft due to spring, excessive extend out to outside main body；Position limiting structure ensured integrated model be not easy by Damage.
