The side of nut 2 is fixed with the connector 4 for connecting door leaf, and opposite side is fixed with roller 3 by connecting pin 31.In addition, also
Including the roller slideway 5 being be arranged in parallel with screw mandrel 1 and bit switch 6 is locked into, the roller slideway 5 matches somebody with somebody to merge with roller 3 can guide rolling
Wheel 3 moves axially along screw mandrel 1.Specifically, in the present embodiment, the roller slideway 5 is groove profile slideway 5, the wheel face of roller 3 and the rolling
The top and bottom sidewall contact of slideway 5 is taken turns, so as to solve tripping problems of the door leaf during switch gate.To make roller 3 protect all the time
Hold the state contacted with the top and bottom sidewall of roller slideway 5, torsion spring (not shown) is provided with nut 2 in the present embodiment.
The side of above-mentioned rollers slideway 5 is provided with fixed seat 8, and the fixed seat 8 includes being used for the first fixation for fixing screw mandrel 1
Block 81 and the second fixed block 82 for fixed idler whell slideway 5, the fixed block 82 of the first fixed block 81 and second are mutually perpendicular to set
Put.The opposite side of roller slideway 5 is provided with locking seat 7, and the locking seat 7 is connected with the end of roller slideway 5, when above-mentioned rollers 3
When being moved to the locked position corresponding to door leaf, the roller 3 leaves roller slideway 5 and the axial rotation of wire winding rod 1 occurs, after
And fall into above-mentioned locking seat 7 and the triggering of nut 2 is locked into bit switch 6, motor power-off, door leaf stops movement, and door-closing in-place is in
Locking device.Specifically, the locking seat 7 includes U-shaped holding groove 71 and guide housing 72, and the guide housing 72 is arranged on holding groove 71
Overthe openings and can guide roller 3 fall into the holding groove 71.
Further, in the present embodiment, guide housing 72 includes the guide section 722 of linear boot segment 721 and arc-shaped, on
Boot segment 721 is stated to flush and be connected with the upper end edge of the end of roller slideway 5, and the free end of guide section 722 and holding groove 71
One end connects, and the other end of the holding groove 71 is connected with the lower end edge of the end of roller slideway 5, carried out more preferably so as to pair roller 3
Ground is spacing.When roller 3 is moved to the locked position corresponding to door leaf, roller 3 slips into boot segment in the presence of inertia first
721, then due to nut 2 rotates, while imported in the presence of guide section 722 in holding groove 71.To make roller 3 more
Locking seat 7, holding groove 71 and the junction formation rounding off of the end of roller 3 are fallen into well, while to enable guide section 722
Preferably guide roller 3, the vertical side walls and guide section 722 of holding groove 71 are tangent.
In the present embodiment, the junction that bit switch 6 is fixed on the end of roller slideway 5 and guide housing 72 is locked into, so as to protect
For card when roller 3 falls into holding groove 71, the trigger unit 21 on nut 2 can trigger immediately is locked into bit switch 6.To make in the present embodiment
Passive locking apparatus structure it is simple, locking seat 7 and roller slideway 5 are integrated part, i.e., locking seat 7 is by rigid material in the present embodiment
Material is made, such as Steel material.
The elastic component 73 for accepting roller 3 is provided with the bottom surface of above-mentioned holding groove 71, when roller 3 falls into holding groove 71
When, elastic component 73 can pair roller 3 enter row buffering, so as to which effective cushion idler 3 falls into the rigid shock power of holding groove 71, avoid pair
The parts such as screw mandrel 1, roller 3 and locking seat 7 cause to damage.Preferably, the elastic component 73 is cushion, and it is laid in holding groove
On 71 bottom surface, and the thickness of the neighbouring side of screw mandrel 1 is more than other side, top surface of its upper end formed with arc transition, so
When roller 3 is fallen into, elastic component 73 can preferably be buffered to it, in addition, when opening the door, the top surface of the arc transition can aid in
Roller 3 slips into roller slideway 5 again.Further, the side evagination of above-mentioned holding groove 71 is formed for branch in roller slideway 5
The supporting part 711 of nut 2 is supportted, and elastic component 73 stretches out and fills the supporting part 711.By setting supporting part 711 to spiral shell
Mother 2 is supported, buffered, and switch gate action can be made more steady.
The course of work of passive locking device is as follows in the present embodiment：
Door closing procedure：Screw mandrel 1 rotates under motor driving, and under the drive of screw mandrel 1 along screw mandrel 1 axle occurs for nut 2
To rectilinear movement, the roller 3 on nut 2 moves linearly along roller slideway 5, drives door leaf to move by connector 4 by nut 2
It is dynamic.When roller 3 is moved to the locked position corresponding to door leaf, the roller 3 leaves roller slideway 5, while screw mandrel 1 runs into axle
To resistance and the resistance can not be overcome so that nut 2 is changed into rotation by axially rectilinear movement, and roller 3 is fallen into along guide housing 72
In holding groove 71, and depress the trigger unit 21 on nut 2 and be locked into bit switch 6, motor power-off, door leaf stops movement, and shutdown is arrived
Position is simultaneously in locking device.
Door opening process：Screw mandrel 1 rotates backward, and when enabling originates, the axial resistance of holding groove 71 causes nut 2 reversely to revolve
Turn, so that roller 3 enters in roller slideway 5 along guide housing 72, then the reverse linear of nut 2 is moved, and realizes door opening action.
