Embodiment
Following execution mode can make those skilled in the art more fully understand the present invention, but does not limit the present invention in any way.
The present invention includes switchgear column 5, door-plate 7, Yi Bian switchgear column 5 is equipped with the fixedly hinge 13 of door-plate 7; The another side of switchgear column 5 is equipped with locking pin 4, is used for locking door-plate 7, door-plate 7 another side the guide plate 2 of upper and lower slip is housed; Have hardy hole 15 Fig. 9 on the guide plate 2, locking pin 4 is locked in the hardy hole 15, and the rotation door lock 6 that pins guide plate 2 is housed in door-plate 7 fronts; On the rotation door lock 6 eccentric locking plate 8 is housed; Eccentric locking plate 8 links to each other with guide plate 2 through locking bar 9, through the locking of guide plate 2 with locking pin 4, realizes that the switchgear door-plate must lock and open; Must lock with guide plate 2 through rotation door lock 6, to prevent misoperation.
The guide plate side has slotted hole 16, and door-plate 7 sides are provided with circular hole 17, and slotted hole 16 and circular hole 17 are fixing through pin 3.Locking bar 9 is welded on the front of guide plate 2, and 3 the right sides of slotted hole and door-plate through a guide plate side left side of pinning are to company.To be installed in be the right side of door-plate Fig. 8 to guide plate Fig. 4 through pinning 3, and can slide up and down through the Chang Yuan hole 16 on the guide plate.
The bent plate 14 that has been welded on the guide plate 2, the screw rod 11 that has been welded on the bent plate 14 is equipped with handle ball 12 on the screw rod 11, be used for making its upper and lower moving.
Guide plate is positioned at the ornamental strip 1 of riveting dress on the door-plate 7.Make its appearance looks elegant.
Utilize locking that hardy hole 15 on the guide plate runs stop pin nail 4 on the equipment column of pass jointly and open.During opening door operation, open the rotation door lock 6 on the door-plate with key, the rotation dead bolt makes eccentric locking plate 8 rotations; Locking bar 9 moves to the door lock direction under spring 10 effects, guide plate 2 releases, and portable handle ball 12 moves up guide plate; Guide plate can the upper and lower slip along the door-plate side; Spacing by the slotted hole 16 of guide plate side when putting in place, the locking pin 4 on the column is in the great circle of hardy hole 15 on the guide plate at this moment, has removed the locking of guide plate 2 and column 3.
When closing door operation, portable handle ball 12 makes guide plate be moved upwards up to upper, the door-plate that closes, and pressing down handle ball 12, that guide plate is moved down into is the most the next; Lean on the pin 3 of door-plate side spacing with slotted hole 16 when putting in place, the locking pin 4 on the column 5 is in the aperture of hardy hole 15 on the guide plate at this moment, and guide plate 2 is locked on the column 5; Both door-plate 7 was locked on the column, rotation Door-lock bolt, eccentric locking plate 8 rotations; Promote locking bar 9 and move to right, insert in the circular hole 17 of guide plate 2 sides, and pin with key; At this moment, guide plate 2 is locked, and can not upwards lift again.
