Fig. 2 is the side view of the split type upper rail of subway sliding door of the present utility model；
Fig. 3 is the side, sectional of subway sliding door of the present utility model some other embodiment of split type upper rail
Figure.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, mounting base, 2, upper rail, 11, supporting part, 12, limiting section, 13, chute, 21, traction grooved, 22, sliding block.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Embodiment：As illustrated in fig. 1 and 2, the split type upper rail of the subway sliding door of the present embodiment, it is characterised in that：Bag
Include mounting base 1 and two upper rails 2；
Above-mentioned mounting base 1 and two upper rails 2 are laterally set；
Two above-mentioned upper rails 2 are arranged on the lower front of above-mentioned mounting base 1 side by side；
Above-mentioned upper rail 2 is the trough body structure of front openings, is provided with the inside of the cell wall of the above-mentioned lower end of upper rail 2 along left and right
The traction grooved 21 that direction extends and walked with the roller for sliding door upper end.
In installation process, by the roller of door upper end as in the notch of upper rail 2, and roller lower end is set to stretch into traction grooved 21
Interior, the guide rail of door lower end and lower section is slidably matched, and plays a supporting role on the door, makes the roller of its upper end without departing from traction grooved,
Under external force, sliding door so that roller can move in the interior edge traction grooved 21 of upper rail 2, accordingly, in each upper rail 2
Place is respectively mounted a door, and two badges draw the action for coordinating and can be achieved to open the door and close the door.
Preferably, the rear side of each above-mentioned upper rail 2 passes through multiple spaced bolts through it and installation bottom
Plate 1 is connected, and its installation strength is higher, and structure is more stable, durable in use, it is preferred that equidistantly interval is set multiple bolts
Put, and form a line in left-right direction.
Preferably, as shown in figure 3, in certain embodiments, the rear side of each above-mentioned upper rail 2 between the upper and lower every transverse direction
Sliding block 22 provided with two bar shapeds, it is respectively equipped with the anterior end surface of above-mentioned mounting base 1 one-to-one with above-mentioned sliding block 22
Two chutes 13, above-mentioned sliding block 22 stretch into corresponding in chute 13, and can be slided along corresponding chute 13, and can be by multiple
Bolt is stated to be connected with mounting base 1, only need to be by upper rail 2 from being pushed away to the other end on front side of one end of mounting base 1 during installation
Enter, but must assure that sliding block 22 can it is deep enough corresponding to chute 13 and moved along chute 13, pull upper rail 2 can will be upper
