Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 1 to 4, a kind of passive locking device for city railway train door system, comprise screw mandrel 1, nut pin assembly 2, supporting slide track 3, position adjustment pad 4, latch 5, transmission pull-fork assembly 6 and torsion spring 7, described screw mandrel 1 is arranged on the pedestal of door system carrying driving mechanism, described nut pin assembly 2 comprises the nut 201 be socketed on screw mandrel 1, be fixed on the roller bolt 202 on nut 201 outer wall, form spiral between described nut 201 and screw mandrel 1 and pass pair, nut 201 is plastic nut, certain cushioning effect is had with before screw mandrel 1, postpone to use, and, plastic nut firmness of the present utility model is higher, can not easily along bad, roller bolt 202 be positioned at screw mandrel 1 side supporting slide track 3 and keep in touch, closing the door in course of action, the moment of torsion that screw mandrel 1 brings makes nut pin assembly 2 produce the trend of rotating to a direction, therefore, nut pin assembly 2 roller bolt be fixed on the supporting slide track 3 held on driving mechanism pedestal and will keep in touch, the nut 201 of restriction nut pin assembly 2 can not rotate by wire winding rod axis before entering locking, supporting slide track 3 is positioned at immediately below roller bolt 202, described transmission pull-fork assembly 6 is arranged on the both sides of nut 201, the aperture of the fork portion of transmission pull-fork assembly 6 is greater than the diameter of screw mandrel, between bigger 1-2mm, thus realize transmission pull-fork assembly 6 and only can realize translation relative to screw mandrel, transmission pull-fork assembly 6 with hang up the door frame of taking putting door leaf and be connected, the axially-movable of nut 201 on screw mandrel 1 passes to door leaf by transmission pull-fork assembly 6, realize unlatching or the closing motion of door leaf, latch 5 is arranged on the end of supporting slide track 3, and be fixed on the pedestal of door system carrying driving mechanism, described latch 5 is provided with groove 501, described groove 501 blocks roller bolt 202 when putting in place for door leaf closing motion, as shown in Figure 4, position adjustment pad 4 is arranged on supporting slide track 3, between latch 5, for the position that door leaf closing motion puts in place, torsion spring 7 is two sections, between nut 201 end being separately positioned on transmission pull-fork assembly 6 tip inside and respective side, described transmission pull-fork assembly 6 is provided with spacing block set 601, in door opening process, the moment of torsion passed over due to screw mandrel 1 is contrary with door closing procedure, the rotation trend away from supporting slide track 3 is there is in nut pin assembly 2 under this torsional interaction, spacing block set 601 can prevent the roller bolt 202 of nut pin assembly 2, rotated wide-angle, the stroke that impact is opened the door.
The course of work of the passive locking device for city railway train door system of the present utility model is as follows,
As Fig. 2, Fig. 3 is in electronic door closing procedure, nut 201 moves to direction of closing the door under the effect of screw mandrel 1, roller bolt 202 is close to the side of supporting slide track 3, when nut 201 advances to the position of door-closing in-place, can not move on due to the mutual extruding between door leaf, now screw mandrel 1 is rotated further under motor effect, drive nut 201 rotates by screw mandrel together, under the acting in conjunction of screw mandrel 1 torque and torsion spring 7, roller bolt 202 turn enters in the groove 501 of latch 5, the extruding force of door leaf adhesive tape acts on the side of latch 5, the moment of friction produced and the elastic force of torsion spring will prevent screw mandrel 1 from reversing away, thus play the effect of locking,
In electric open-door process, because nut 201 is in the groove 501 of latch 5, locking cannot carry out axially-movable along screw mandrel 1, therefore nut 201 overcomes the active force realization reversion of aforementioned friction moment and torsion spring 7 together with screw mandrel 1 under motor effect, roller bolt 202 is screwed out groove 501, roller bolt 202 is made to get back to the position flushed with supporting slide track 3, now due to spacing block set 601, nut 201 is stoped to reverse further, therefore nut 201 leans against spacing block set 601, on under the effect of screw mandrel to enabling direction motion, until open the door put in place, as shown in Figure 1.
When manually closing the door, nut pin assembly 2 with electronic identical regular movement of closing the door to lock position, because screw mandrel 1 is now driven member, therefore can not continue to rotate as electronic closing the door, now torsion spring 7 need overcome the rotational resistance square of screw mandrel 1, roller bolt 201 is fallen in the groove 501 of latch 5, thus realizes the manual locking of door leaf.
Passive locking device for city railway train door system of the present utility model, can apply in the door system lock structure with double door or single open-door, be a simplified the structure of locking system, in new lock structure, associated core part only has 7 (screw mandrels 1, nut pin assembly 2, supporting slide track 3, position adjustment pad 4, latch 5, transmission pull-fork assembly 6 and torsion spring 7), and existing LS lock and global locking device number of parts this numerical value far super, and the surface to coordinate with bearing and Rectangular Spring needs fine finishining, the processing of the screw mandrel locking section of LS lock is also relatively difficult, no matter be from number of parts, or compare from the angle of the complexity of part processing, required cost of the present utility model is all lower than present common technology, and, traditional door system in the latched condition screw mandrel locking section is easy to flange under adhesive tape active force, damage screw mandrel, the cost changing screw mandrel is higher, and in structure of the present utility model, latch 5 bears adhesive tape active force, for consumable accessory, change latch much easier, the cost of latch wants considerably cheaper relative to screw mandrel, reliability is high, has a good application prospect.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
