Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figures 1 to 4, draw out switchgear cabinet is interlocked, and comprises bedplate 111, first latch 120, second latch 130 and thrust unit.Bedplate 111 is provided with supporting plate 112, described supporting plate 112 to be arranged on described bedplate 111 and to project upwards in described bedplate 112.Described supporting plate 112 is provided with spaced upper backup pad 113 and lower supporting plate 118.Upper backup pad 113 is provided with guide through hole 119.Bedplate 111 is also provided with the first fixed head 114, first fixed head 114 to be arranged on bedplate 111 and to protrude from bedplate 111.First fixed head 114 is provided with the second fixed head 115 and the 3rd fixed head 116.Second fixed head 115 is arranged on the first fixed head 114 upper end, is positioned at above bedplate 111.3rd fixed head 116 is arranged on the bottom of the first fixed head 114 above-below direction.Supporting plate 112 in the utility model, supporting bracket 113, first fixed head 114, second fixed head 115 and the 3rd fixed head 116 both can integral type be arranged, and also independently can arrange and connect.
Thrust unit is push pedal 140.Push pedal 140 runs through supporting plate 112, and two ends lay respectively at supporting plate 112 both sides.Push pedal 140 runs through the 3rd fixed head 116.Supporting plate 112 and the 3rd fixed head 116 support push pedal 140, and push pedal 140 can be arranged with moving horizontally.Push pedal 140 is set with the second Compress Spring 141.Second Compress Spring 141 one end is resisted against on supporting plate 112, and the other end is connected with push pedal 140 or is resisted against in push pedal 140.During driven forward push pedal 140, the second Compress Spring 141 is produced elastic deformation force by compressing.After second Compress Spring 141 is compressed, push pedal 140 can be helped to reset.Push pedal 140 is provided with the second chute 142.First fixed head 114 is provided with the second lead 143.Second lead 143 can be plugged in the second gathering sill 142 slidably along the second chute 142 horizontal direction.Push pedal 140 is provided with inclined-plane 144.Push pedal 140 is also provided with draw-in groove 145.
First latch 120 runs through bedplate 111 and the second fixed head 115, and liftably arranges.First latch 120 is provided with the first lead 121.First lead 121 is across above push pedal 140.Push pedal 140 stops that the first lead 121 declines, and can prevent the first latch 120 from dropping.Described first lead 121 protrudes from described first latch 120, and is positioned on the moving direction on described inclined-plane 144; When described push pedal 140 is pushed and moves in the horizontal direction, described first lead 121 is supported on described inclined-plane 144, makes described first lead 121 drive described first latch 120 to rise.First latch 120 is set with the first Compress Spring 122.First Compress Spring 122 one end is resisted against in the second supporting bracket 115, and the other end is resisted against on the first latch 120 or with the first latch 120 and is connected.First latch 120 makes the first Compress Spring 122 compress and produces elastic deformation force when rising.First Compress Spring 122 can help the first latch 120 to reset.
Second latch 130 runs through upper backup pad 113 and lower supporting plate 118, and liftably arranges.Second latch 130 is provided with clamp 131.When clamp 131 inserts in draw-in groove 145, restriction push pedal 140 is moved; Clamp 131 exits after rising with the second latch 130 in draw-in groove 145, and push pedal 140 can move horizontally.Second latch 130 is supported on lower supporting plate 118, prevents from dropping.Second latch 130 is also provided with lower through-hole 132 and upper through hole 133.
Supporting plate 112 is provided with handle (not shown) and rotating disk 151.Handle is connected with rotating disk 151, arranges all rotationally.Rotating disk 151 is provided with the first projection 151 and the second projection 153.Described first projection 152 can be inserted in described lower through-hole 132 rotating clockwise in process with rotating disk 151, and exits in lower through-hole 132 rotating counterclockwise in process with rotating disk 151.When described rotating disk 151 rotates clockwise, described first projection 152 upwards supports described second latch 130 makes described second latch 130 rise.Described second projection 153 inserts in described guide through hole 119 when rotating clockwise with described rotating disk 151, oppresses described second latch 130 and described second latch 130 is declined.The hole wall of described guide through hole 119 is for limiting the rotational angle of described second projection 153, and described second projection 153 rotates clockwise in process when being resisted against described guide through hole 119 right-hand member and cannot be continued to be rotated counterclockwise by described upper backup pad 113 stop.Described second projection 153 can insert in described upper through hole 133 when rotating counterclockwise.
Draw out switchgear cabinet interlocking in the utility model and middle-low voltage switch cabinet, be arranged on extraction structure drawer by interlocking, distribution component relies on the extraction of drawer or pushes control circuit and disconnects or close.Cabinet is arranged two jacks to match with the first latch, the second latch respectively, when the first latch and the second latch insert in jack, drawer and cabinet are locked.When drawer and cabinet lock by interlocking, the first latch and the second latch insert in the jack on cabinet respectively, and clamp inserts in draw-in groove.Now due to the restriction of clamp, thrust unit cannot promote.When needing to extract drawer out, rotatable handle drives rotating disk and the first projection to rotate, and promote the second latch when the first projection rotates and rise, exit when the second latch rises in the jack of cabinet, clamp exits in draw-in groove simultaneously, and now thrust unit can promote.Support when thrust unit promotes after the first latch makes the first latch rise and exit in the jack of cabinet, remove the locking of drawer and cabinet.At released state, the first resetting means and the second resetting means all have elastic force.When needing locking, remove the thrust to thrust unit, thrust unit resets under the effect of the second resetting means, and remove and support power to the first latch, the first latch resets and reinserts in the jack of cabinet under the effect of the first resetting means.Reverse rotation handle drives rotating disk and the second projection reverse rotation, and the second projection is oppressed after the second latch declines and inserted in the jack of cabinet.Drawer and cabinet lock by the first latch and the second latch.
Upper and lower, left and right in the present embodiment, clockwise, counterclockwise all with accompanying drawing 4 for reference, for more clearly describing the relative concept that the utility model uses, do not form the restriction to right.
Embodiment in the utility model, only for being described the utility model, does not form the restriction to right, other equivalent in fact substituting, all in the utility model protection range that those skilled in that art can expect.
