Abstract
The utility model discloses an unlocking key special for an electromagnetic lock of a high-pressure switch device, which comprises an operation rod and a bump. The bump is fixedly connected to one end of the operation rod and a supporting rod, the other end of the supporting rod is movably connected to a movable board, a return spring is sleeved on the supporting rod, and two ends of the return spring are respectively supported on the bump and the movable board. A button block is fixedly arranged on the movable board, a switch, an alarm and a battery are fixedly arranged on the bump, the button block and the switch are arranged face to face, and the switch is in series connection between the alarm and the battery. The unlocking key special for the electromagnetic lock does not change the operation method of an existing unlocking key, and is simple in structure and capable of reminding users to operate in time, thereby guaranteeing the performance of the electromagnetic lock.
Description
Technical field
The utility model relates to a kind of unlock key, refers in particular to be used for the unlock key of high voltage switchgear equipment with electromagnetic lock.
Background technology
Electromagnetic lock is one of high voltage switchgear equipment lockset commonly used, is installed on the high-tension switch cabinet door, and the equipment in the switchboard is worked to prevent maloperation.The structure of electromagnetic lock commonly used is: locking bolt, coil and lock core are installed in lock body; Lock core is installed in the coil rack; By the front and back action of coil switching electric control lock core, the front and back action of lock core realizes the locking and unlocking of locking bolt, realizes the electromagnetic lock operation thereby manually spur locking bolt.
For preventing the malfunctioning of coil and lock core action; All electromagnetic locks all are equipped with the emergency release key; This emergency release key is that the front end at action bars is provided with a convex structure; Stretch into the corresponding position of lock body, just can forcibly promote lock core by rotation convex structure and move to unlocked position, thereby realize the emergency release function from the locking bolt latched position.During practical operation, operating personnel generally are the left-handed operation unlock keys, right hand pulling locking bolt; After the locking bolt release; Operating personnel often forget unlock key are taken off or unlock key is restored to the original state that this just causes electromagnetic lock to be in released state all the time, and operating personnel are when carrying out next step operation; Locking bolt still can be freely movable, causes electromagnetic lock optionally to be locked and to open.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of existing unlock key when operating, provide a kind of electromagnetic lock special-purpose unlock key, can reminding operating personnel after using unlock key, should take off perhaps constantly unlock key is restored to the original state.
The technical scheme that the utility model adopts is: comprise action bars and projection; Affixed action bars one end of projection, the affixed support bar of projection, the support bar other end flexibly connects portable plate; Be with back-moving spring on the support bar, the two ends of back-moving spring are supported in respectively on projection and the portable plate; Fixedly install a button piece on the portable plate, be set with switch, alarm and battery on the projection, the button piece arranges face-to-face mutually that with switch switch series is connected between alarm and the battery.
The utility model does not change the mode of operation of original unlock key, and is simple in structure, ability instant alerts operating personnel, thereby the performance of assurance electromagnetic lock.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain;
Fig. 1 is the structural representation of the utility model;
Among the figure: 1. action bars; 2. projection; 3. back-moving spring; 4. support bar; 5. portable plate; 6. button piece; 7. switch; 8. alarm; 9. battery.
The specific embodiment
Referring to Fig. 1, the utility model comprises action bars 1 and projection 2, and projection 2 is fixed on an end of action bars 1, and the other end of action bars 1 supplies the hand-held usefulness of operating personnel.On projection 2, be fixedly connected a support bar 4; The other end of support bar 4 flexibly connects portable plate 5, and portable plate 5 can be established back-moving spring 4 along support bar 4 move left and right on support bar 4; Back-moving spring 4 is enclosed within on the support bar 4, and the two ends of back-moving spring 4 are supported in respectively on projection 2 and the portable plate 5.Fixedly install a button piece 6 on the portable plate 5, also fixedly install switch 7, alarm 8 and battery 9 on the projection 2; Button piece 6 and switch 7 arrange mutually face-to-face, and the distance between button piece 6 and the switch 7 with less than the unlock key distance that the promotion lock core moves when the work.Switch 7 is electrically connected alarm 8 and battery 9 respectively, is about to switch 7 and is serially connected between alarm 8 and the battery 9.
The utility model is when work, thereby rotary manipulation bar 1 drives projection 2 rotations, is promoted the lock core of electromagnetic lock earlier by portable plate 5; At the lock core continued rotary manipulation bar 1 that puts in place; Otherwise lock core promotion portable plate 5 overcomes the spring power of back-moving spring 4 to be moved to the left, and by button piece 6 push switches 7, thereby opens alarm 8; Alarm 8 is reported to the police, and this moment, the release of unlock key ability put in place.After having operated electromagnetic lock, if not immediately to the unlock key commence operation, then alarm 8 is in alarm condition all the time, plays the effect of reminding operating personnel.
