Keeper on bottom plate, the conveyor screw has a spiral protrusion, and the keeper has an oblique slot, the spiral protrude with it is oblique
Groove snap fit, position limiting structure is provided between the conveyor screw and switching knob.
As the improvement of above-mentioned technical proposal, the position limiting structure is connecting rod, and the spiral body side surface has screwed hole, institute
State connecting rod and be fixedly installed threaded rod close to the side of conveyor screw, the threaded rod is threadedly coupled with screwed hole；The switch rotation
Extension, which is formed in rotating bar, the rotating bar, in the lateral drawer of button one has on block, the connecting rod close to the side of rotating bar
Positive stop end with constraint block rotation.
As the improvement of above-mentioned technical proposal, the number of the block is two, is symmetrically distributed in up and down the two of rotating bar
There is arc groove, the arc groove is fitted with rotating club body between side, the positive stop end.
It is described when conveyor screw is rotated and reaches fastening state with keeper as the improvement of above-mentioned technical proposal, screw thread
Bar opposed helical body is relatively rotated and produces lateral displacement, and the arc groove of connecting rod is slided along rotating bar and on connecting rod
Positive stop end staggers with block.
As the improvement of above-mentioned technical proposal, cross spacing block, the transverse direction are provided with the rotating bar between block
Limited block is in connecting rod side, the cross spacing block constrained linkage transverse shifting when turning to close to conveyor screw side.
As the improvement of above-mentioned technical proposal, the side on the conveyor screw away from screwed hole is provided with locking hole.
As the improvement of above-mentioned technical proposal, the height and position phase of switching knob and the locking hole of conveyor screw on the drawer
Together, display screen and handle are additionally provided with the drawer.
In above-mentioned technical proposal, when drawer is active, conveyor screw is separate with keeper, now connecting rod
Positive stop end is mutually constrained with block, and now switching knob can not be rotated freely when mechanical interlock mechanism is not locked；Work as conveyor screw
When rotating and reaching fastening state with keeper, the positive stop end on connecting rod staggers with block, and now switching knob is in mechanical interlocking
Mechanism can be rotated freely after having locked, so as to avoid power initiation when mechanical lock mechanism is not opened in the prior art from existing
Potential safety hazard, beneficial effect is notable.

Embodiment
As shown in Figure 1 and Figure 2, the invention provides a kind of fool proof draw-out type low voltage switch cabinet, including drawer 10,
The drawer 10 is supported on the base plate 20, has switching knob 30 and mechanical interlock mechanism, the mechanical lock on the drawer 10
Tight mechanism includes the conveyor screw 40 being arranged in drawer 10 and sets keeper 50 on the base plate 20, and the conveyor screw 40 has
Spiral protrudes 42, and the keeper 50 has oblique slot 51, and the spiral protrudes 42 and the snap fit of oblique slot 51, the spiral
Be provided with position limiting structure between body 40 and switching knob 30, wherein spiral protrudes 42 and can rotated, rotation rear screw protrude 42 with
The gradually snap fit of oblique slot 51, realizes the mechanical caging to drawer 10.
Further, the position limiting structure is connecting rod 60, and the side of conveyor screw 40 has screwed hole 43, the connecting rod 60
Side close to conveyor screw 40 is fixedly installed threaded rod 61, and the threaded rod 61 is threadedly coupled with screwed hole 43；The switch
Extension is formed in rotating bar 31, the rotating bar 31 to have and leaned on block 32, the connecting rod 60 in the lateral drawer 10 of knob 30 1
The side of nearly rotating bar 31 has the positive stop end 62 that constraint block 32 rotates.Wherein, in order to improve stop 32 binding effect, institute
The number for stating block 32 is two, and being symmetrically distributed between the both sides up and down of rotating bar 31, the positive stop end 62 has arc recessed
Groove 63, the arc groove 63 is fitted with the shaft of rotating bar 31.In the preferred scheme, when drawer 10 is active, spiral shell
Revolve body 40 and keeper 50 is separate, now the positive stop end 62 of connecting rod 60 is mutually constrained with block 32, and rotating bar 31 can not be certainly
By rotating, i.e., switching knob 30 can not be rotated freely when mechanical interlock mechanism is not locked；When conveyor screw 40 rotate and with positioning
When part 50 reaches fastening state, the opposed helical body 40 of threaded rod 61 relatively rotates and produces lateral displacement, the arc of connecting rod 60
Connected in star 63 is slided along rotating bar 31 and the positive stop end 62 on connecting rod 60 staggers with block 32, and now rotating bar 31 can be free
Rotate, i.e., switching knob 30 can be rotated freely after mechanical interlock mechanism has been locked, so as to avoid machinery in the prior art
The potential safety hazard that power initiation is present when locking mechanism is not opened.
Further, as shown in figure 3, being provided with cross spacing block between two blocks 32 in the rotating bar 31
33, the cross spacing block 33 is in the side of connecting rod 60, the cross spacing block 33 when turning to close to 40 side of conveyor screw
The transverse shifting of constrained linkage 60, the preferred scheme passes through cross spacing block 33 so that switching knob in the technology of such scheme
30 after power-on, and mechanical interlock mechanism can not unlock, only after switching knob 30 rotates and closes power supply, laterally
Limited block 33 just releases the lateral confinement to connecting rod 60, and then just can release mechanical interlocking machine by the rotation of conveyor screw 40
The lock-out state of structure.
In the above-described embodiments, the side on the conveyor screw 40 away from screwed hole 43 is provided with locking hole 41, the locking
The effect in hole 41 is to coordinate convenient to the progress rotation process of conveyor screw 40 with corresponding spanner；Further, the drawer 10
Upper switching knob 30 is identical with the height and position of the locking hole 41 of conveyor screw 40, limit both position relationship be with drawer
Mechanical interlock mechanism is mutually corresponded to, it is ensured that mechanical interlock mechanism is normally worked, also, display is additionally provided with the drawer 10
Screen 11 and handle 12.
