Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described further.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
nullAs shown in Figures 1 and 2，Bottom guiding mechanism for city railway train door leaf of the present utility model，Guide rail 1 is drawn including the plug being arranged on car body 2，Described plug draws the groove 16 having on guide rail 1 for positioning changeover module 11，The upper end plug of described groove 16 is drawn and is additionally provided with guide roller baffle plate 15 on guide rail 1，It is socketed with guiding trestle 6 on described changeover module 11，Two ends of described guiding trestle 6 are respectively fixed with the first switching roller 10、Second switching roller 14，The side of described first switching roller 10 is provided with roller supporting bar 7，Described roller supporting bar 7 is provided with detent 8，The described front end having detent 8 is provided with support bar baffle plate 9，Described roller supporting bar 7 is fixed on the door leaf 3 below slide block 5，Described slide block 5 is embedded in line slideway assembly 4，Described line slideway assembly 4 is arranged on door leaf 3，Described first switching roller 10 can be absorbed in or depart from the detent 8 of roller supporting bar 7，Described second switching roller 14 can be absorbed in or depart from the groove 16 that plug draws guide rail 1，When closing door leaf，Described first switching roller 10 is absorbed in detent 8，Described second switching roller 14 departs from groove 16；During opened door leaf, described first switching roller 10 departs from detent 8, and described second switching roller 14 is absorbed in groove 16.
Being provided with cover plate 12 between described first switching roller the 10, second switching roller 14, described cover plate 12 is fixed on guiding trestle 6 by screw 13.
nullBottom guiding mechanism for city railway train door leaf of the present utility model，Specific works process is as follows，When door leaf is by closed mode to opening，Time initial, second switches roller 14 and draws at plug and roll on guide rail 1，First switching roller 10 is then absorbed in the detent 8 of roller supporting bar 7，Then at the end of door leaf motion draws guide rail 1 to plug，Second switching roller 14 is directed to roller baffle plate 15 to be stopped，Now，The the second switching roller 14 drawing guide rail 1 to contact on changeover module 11 with plug enters groove 16，First switching roller 10 departs from from the detent 8 of roller supporting bar 7，It is rolled in the plane of roller supporting bar 7，Simultaneously，Slide block 5 setting in motion in line slideway assembly 4 is until door leaf is opened fully to the stroke required，Bottom after door leaf is opened guides mechanism structure schematic diagram，As shown in Figure 3.
When door leaf is begun to shut off by full open position, first slide block 5 setting in motion, the first switching roller 10 is driven to move to contact with the support bar baffle plate 9 on roller supporting bar 7, now the first switching roller 10 embeds the detent 8 of roller supporting bar 7, second switching roller 14 of the other end departs from from groove 16, and the second switching roller 14 draws surface scrolls smooth on guide rail 1 at plug, until door leaf completely closes, bottom after door leaf cuts out guides mechanism structure schematic diagram, as shown in Figure 4.
In sum, bottom guiding mechanism for city railway train door leaf of the present utility model, can be suitable in the case of space between the edge-on cover of car body and vehicle body side wall structure is less, and need not synchronizing bar, the design integrated for the edge-on cover of car body is provided convenience, and reduces the space that guiding mechanism takies in the height direction, simple in construction, easily realize, have a good application prospect.
