Please in conjunction with the accompanying drawings 1 and 2e shown in, safety door latch of the present invention comprises the two large divisions, promptly be installed in assembly and the assembly that is installed on the fixed gate 12 on the dodge gate 11, driving-belt 1212 wherein is fixed on the motor driving wheel of fixed gate 12 and the driven pulley (not shown go out), and fixedlys connected with dodge gate 11 by connector 1101.Assembly on fixed gate 12 comprises: form the first swing armed lever by gear wheel 1201, armed lever 1202, spring spacer pin 1203 and spring 1204 and axle 1206, wherein gear wheel 1201 is fixed on the rear side of armed lever 1202, depression bar 1205 is fixed on the armed lever 1202, axle 1206 links together armed lever 1202 and adjustment seat 1207, adjustment seat 1207 is embedded in pedestal 1208, pedestal 1208 is fixed on the fixed gate 12, and spring spacer pin 1203 and spring 1204 are fixed on the below of armed lever 1202.On this first swing armed lever and dodge gate second swung armed lever and matched.

Assembly on the dodge gate 11 comprises following components: the one, and connector 1101, upper cover plate 1102, slide block 1103, pinch roller 1104, Slide Box 1105, spring 11063 and spring spacer pin 11073 are formed a gear box, wherein connector 1101 and pinch roller 1104 are fixing with slide block 1103 on Z-direction, upper cover plate 1102 is fixed on the top of slide block 1103, and spring 11063 and spring spacer pin 11073 are fixed on the X-direction of Slide Box 1105.The second swing armed lever is made up of spring 11062, spring spacer pin 11072, pedestal 1109, axle 1110, armed lever 1111 and jumping wheel 1112, it is fixing with pedestal 1109 by axle 1110 wherein to have fixed the armed lever 1111 of jumping wheel 1112, and be connected with carriage 1108, spring 11062 and spring spacer pin 11072 be fixed on the Y direction pedestal 1109 below.Gear box is fixed on the carriage 1108 by its Slide Box 1105, and two parts are combined.

Above-mentionedly be mechanical composition of the present invention, in addition, the present invention also include cooperatively interact near switch 1209 with near inductive switching sheet 1116, the former is connected the lower-left end of armed lever 1202 by a connection piece (not shown go out), the latter is arranged on the lower-left end of the armed lever 1111 of dodge gate 11.Be that guiding needs, the present invention also comprises one stroke switching guide 1115, is fixed on the afterbody of dodge gate, matches to use with the travel switch 1210 of closing the door on the fixed gate 12 and plays guiding.

Describe the course of work of the present invention in detail below in conjunction with said structure.

See also Fig. 2 a-2d, wherein Fig. 2 a is that station platform safety door of the present invention is locked in to be in and closes and locking state, and the height that jump wheel 1112 this moment is lower than gear wheel 1201.Fig. 2 b begins to start release, dodge gate 11 moves to left, slide block 1103 rolls on depression bar 1205 and presses down this depression bar 1205, jumping wheel 1112 clockwise rotates around the axle 1110 of the second swing armed lever, gear wheel 1201 rotates counterclockwise around the axle 1206 of the first swing armed lever, idle stroke drive slide block 1103 by driving-belt 1212 makes this slide block 1103 to left dislocation, on the dodge gate 11 near inductive switching sheet 1116 gradually with fixed gate 12 on be separated near switch 1209, from Fig. 2 d to 2e, realized two-part separation fully, because the change of the two position relation, make near inductive switching sheet 1116 and leave detected scope, send the signal that lock is untied fully, dodge gate 11 continues to slide left then, travel switch guiding 1115 on the dodge gate 11 shifts out left near switch 1210, should send enabling signal near switch 1210 then.

The locking process of Fig. 3 a-3c is opposite with above-mentioned releasing process, and the first swing armed lever clockwise rotates around axle 1206, and the second swing armed lever rotates counterclockwise around axle 1110, during to Fig. 3 c position, jumps wheel 1112 and highly is lower than gear wheel 1201.In case door is closed, near inductive switching sheet 1116 and overlapping, transmit locking signal near switch 1209 near switch 1209, travel switch 1210 and travel switch guiding 1115 spreads out of the buttoned-up signal of door by closing the door.Again by spreading out of the locked signal of door near switch 1209 with near inductive switching sheet 1116.

If when running into special circumstances and need open Door by Hand, the operator raises manual unlocking spacing 1117 and triggers manual unlocking travel switches 1211 and provide the manual unlocking signal by lifting manual unlocking steel wire 1113, the formation of the trip switch 1211 and the travel switch 1210 of closing the door is in full accord, in this process, mention armed lever 1111, make jumping wheel 1112 cross gear wheel 1201 and reach the release purpose, after the release, dodge gate 11 skids off and provides enabling signal, in like manner, when closing, dodge gate 11 also can send the signal of closing the door and locking, the manual unlocking signal that spreads out of by release fixation with steel wire device 1114 and manual unlocking spacing 1117 and manual unlocking travel switch 1211.Travel switch guiding 1115 is fixed on the dodge gate, is used with the travel switch 1210 of closing the door and plays guide effect.This manual unlocking part is used by the manual unlocking travel switch 1211 on release fixation with steel wire device 1114 and the fixed gate 12.Specifically see also Fig. 4 a-4d and illustrated the process of manual unlocking.

More than all embodiment only for the explanation the present invention usefulness, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present invention and should be limited by each claim.
