Fig. 2 is the profile of operating mechanism in the status lock buckle device of a kind of draw out switchgear electrical equipment of the present invention.
Embodiment
Below in conjunction with diagram, the preferred embodiments of the present invention are elaborated.
As shown in Figure 1, the status lock buckle device of this draw out switchgear electrical equipment is placed in main body frame, is used in conjunction with Switch main body, the latch gear 2 and the sensitive switch 3 that comprise operating mechanism 1, link with operating mechanism 1.Operating mechanism 1 is located in main body frame, comprises the slide block 101 that can slide up and down in holder 102 and the release spanner 103 that can slide up and down with movable slider 101, and wherein, holder 102 is to be fixed by screws on the left plate of main body frame.Latch gear 2 comprises the lock pin frame 201 being fixed on main body frame base plate and is arranged on the lock pin 202 on lock pin frame 201 by elastic reset member, and lock pin 202 coordinates with the lockpin hole that is positioned at Switch main body bottom, and lock pin 202 can link with above-mentioned slide block 101.Sensitive switch 3, for the intrinsic circuit of cut-off switch, is fixed on main body frame by switch base 4, and can with described slide block 101, link by the rotating part 7 being rotatably installed in main body frame.
The operation principles of said structure is, release spanner 103 be with movable slider 101 in holder 102 upwards or down sliding, thereby band pendulum lock pin 201 in lock pin frame 201 upwards or move downward.When lock pin 201 moves upward, lock pin 201 can engage with the lockpin hole of Switch main body bottom, plays the effect of lockup switch body, and Switch main body can not skid off in main body frame; When moving downward, lock pin 201 withdraws from pine in lockpin hole, play the effect of release, and Switch main body can freely be come in and gone out in main body frame.When release, slide block 101 can touch rotating parts 7, and rotating part 7 can trigger sensitive switches 3 and move, thereby the intrinsic circuit of cut-off switch cuts off the power supply of Switch main body, has guaranteed the safe operability of Switch main body.
Preferably, above-mentioned holder 102 is equipped with mounting hole with slide block 101, one end of release spanner 103 is connected with the rotating shaft 6 being fixed on main body frame through the mounting hole of holder 102 and slide block 101, one end of release spanner 103 can 6 be swung up and down around the shaft in mounting hole, and the hunting range of release spanner 103 is subject to the restriction of above-mentioned mounting hole.Above-mentioned release spanner 103 swings up and down is with movable slider 101 to slide up and down in holder 102 then.
Further, above-mentioned rotating part 7 is for can rotate around the axis, and has at least two ends, and its one end is connected with the left plate of main body frame by elastic reset member, and the other end contacts with the shell fragment 8 for triggering sensitive switch 3.When above-mentioned release spanner 103 upwards swings, slide block 101 upward sliding thereupon, thus the end shake-up rotating part 7 of slide block 101 is swayed, now, the other end of rotating part 7 can trigger sensitive switch 3 and move, the intrinsic circuit of cut-off switch.After this process completes, rotating part 7 can be got back to original position under the effect of elastic reset member.It should be noted that herein and can also contact by this rotating part 7 and the device that driving switch body skids off main body frame.For example, device for switching itself possesses a kind of driving switch body and skids off the device of main body frame, and this device is the slip that drives actuator drives Switch main body by the rotation of shake handle 12 (as shown in Figure 1), above-mentioned rotating part 7 can be set to have so a kind of element of three ends, one of them end is positioned at the holder for fixing shake handle 12, the end that can touch the rotating part 7 that is positioned at this holder when shake handle 12 inserts in above-mentioned holder, thereby rotating part 7 is rotated, touching sensitive switch 3 moves, the intrinsic circuit of cut-off switch.
Further, above-mentioned latch gear 3 comprises the left latch gear and the right latch gear that are symmetricly set on main body frame base plate both sides.Between left latch gear and right latch gear, be provided with connecting rod 9, under the draw of connecting rod 9, can realize the synchronization action of left latch gear and right latch gear, and left latch gear and right latch gear lock pin by the first pendulum plate 10, be connected with connecting rod 9 respectively, first pendulum plate 10 is connected with connecting rod 9 bearing pins.Preferably, the first pendulum plate 10 is leg-of-mutton connecting plates, is fixed on the base plate of main body frame by fixed head (not shown), be connected, and the first pendulum plate 10 is fixedly connected with lock pin 201 between the first pendulum plate 10 and fixed head by bearing pin.In addition, one end of connecting rod 9 is connected with one end bearing pin of slide block 101 by the second pendulum plate 11, and preferably, the structure of this second pendulum plate 11 is identical with the structure of the first pendulum plate 10.When slide block 101 moves upward, the second pendulum plate 11 meeting traction link 9 are to left movement, and connecting rod 9 drives again the first pendulum plate 10 being attached thereto to pull lock pin 201 to move downward.
What preferably, above-mentioned elastic reset member all adopted is spring 5.
Above embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement accordingly, can not limit the scope of the invention.All equalizations of doing with the claims in the present invention scope change and modify, and all should belong to the covering scope of the claims in the present invention.
