Abstract

An operating mechanism for an automatic transfer switch belongs to the technical field of low-voltage electrical appliances, and comprises a shell, a manual operating rod and a shifting rod. The shell is provided with a manual operating hole, a first position, a second position and a third position are used for indicating an automatic operating state, a manual operating state and a locked state of the operating mechanism respectively and marked on the outer lateral side of a panel of the shell. The shifting rod is slidably arranged on the shell and moves among the first position, the second position and the third position. The operating mechanism is characterized in that the operating mechanism further comprises a baffle which is pivoted to the shell and connected with the shifting rod, the shifting rod can drive the baffle to rotate during sliding, and the manual operating hole on the shell is opened or closed by the baffle. The operating mechanism for the automatic transfer switch has the advantages that manual misoperation can be effectively prevented when the operating mechanism is in the automatic operating state or the locked state, so that the operating mechanism is protected from damage, and personal safety of operators can be guaranteed.

Technical field

The utility model belongs to the low voltage electrical apparatus technology field, is specifically related to a kind of operating mechanism that is used for automatic change-over

Background technology

will use all in low-voltage electrical apparatus such as automatic change-over switch equipment that operating mechanism closes, separating brake or other action.Operating mechanism generally all is to accomplish automatic operating process by controller, but toward the contact meeting manual operation function is provided, so that under the situation that operation failure perhaps needs go to operate by hand automatically, can remove to operate this operating mechanism by manpower.During manual operation, operating personnel can insert the manual operation interface at the manual lever top of operating mechanism with handle or other annex, thereby drive the manual lever action, accomplish the manual operation process.

The manual operation interface of existing operating mechanism directly is positioned on the panel of operating mechanism housing, and this form benefit is simple in structure, easily manufactured.But its drawback also is conspicuous; One of which, because be under the automatic mode of operation at it; The manual operation interface of this kind structure promptly still can be activated by handle or other annex still by visible, so cause the damage of operating mechanism easily even threaten operating personnel's personal safety; Two, when the user in when maintenance; Usually operating mechanism is placed lock-out state, but since the manual operation interface still by visible, promptly still can be activated by handle or other annex; So limit others removes to operate electrically operated device effectively, therefore there is potential safety hazard.

In view of above-mentioned prior art; Be necessary the existing operating mechanism that is used for automatic change-over is improved, for this reason, the applicant has carried out good try; Found the way that solves the problems of the technologies described above, the technical scheme that will introduce below produces under this background

Summary of the invention

The purpose of the utility model is that a kind of operating mechanism that is used for automatic change-over will be provided; It can be at operating mechanism and effectively stop artificial manual misoperation under automatic operation or the lock-out state; Thereby can make operating mechanism exempt from damage, and ensure operating personnel's personal safety.

The purpose of the utility model reaches like this; A kind of operating mechanism that is used for automatic change-over; Comprise housing, manual lever and driving lever; Offer the manual operation hole that is used to supply the manual lever inserting on the described housing; Identify respectively on the lateral surface of the panel of said housing to be useful on and represent that operating mechanism is in the primary importance of automatic mode of operation, the second place of manual operation state and the 3rd position of lock-out state, described driving lever is slidingly arranged on the housing and between described primary importance, the second place and the 3rd position, moves, and be characterized in: described operating mechanism also comprises a baffle plate; This baffle plate is positioned at the below of described driving lever; And pivotal connection is rotated when described driving lever can drive described baffle plate when sliding, and is realized the opening and closing of fault to the manual operation hole on the housing by baffle plate on housing.

In the specific embodiment of the utility model, offer elongated slot on the described housing; One end pivoting of said baffle plate is connected on the housing, the middle part offers guide groove, offer the manual operation via hole on the other end; Described driving lever convexes with push rod, turns round on a side side of housing, convexing with to dial on a side side of housing dorsad, described push rod holds and fits in the described guide groove, turns round to hold for described group to fit in the described elongated slot.

are in another specific embodiment of the utility model; Be equipped with muscle portion on the medial surface of the panel of said housing; In described muscle portion, be formed with and be used to the sliding chamber that supplies described driving lever to slide within it; Be respectively arranged with bayonet socket in the described muscle portion and on corresponding to primary importance, the second place, the 3rd position, corresponding ground extends on described driving lever and is useful on the card base that matches with bayonet socket.

also convex with one first on the medial surface of the panel of said housing in another specific embodiment of the utility model, narrow the contracting in said first top has second, offers screw hole in the axial centre at second top; Offer through hole on one end of said baffle plate; Baffle plate is set on first through through hole; On one gasket sleeve the is located at second and surface of packing ring and the boss of first and second formation lean; One screw revolves with screw hole after passing packing ring, through hole successively joins, and makes an end of baffle plate rotate and realize the pivotal connection with housing around first.

the utility model is through being provided with baffle plate; Slip by driving lever drives the baffle plate rotation; Realization is under the automatic mode of operation at operating mechanism the unlatching and the sealing of manual handle hole, and manual lever is covered by baffle plate; Handle can't insert and carry out manual operation in the manual lever, thereby has prevented that effectively operating mechanism from artificial misoperation occurring under the mode of operation automatically; When the needs manual operation, the push rod of driving lever drives baffle plate through guide groove and rotates, and the position in manual operation via hole and manual operation hole is coincided, and at this moment manual lever is not covered by baffle plate, and handle can insert and carry out manual operation in the trigger rod; When needs locked, baffle plate was again with the manual operation maskaperture mask on the housing, and promptly handle can't be operated this operating mechanism, had prevented that artificial misoperation from appearring in operating mechanism under lock-out state, guaranteed maintainer's personal safety.
