Preferably, the quantity of described main skid mechanism is two groups and is evenly distributed on described skid mainboard, and described in every group, main skid mechanism includes running roller seat and is installed on the first running roller on described running roller seat; Two described running roller seats lay respectively at the both sides of described skid mainboard; The line of centers of described skid mainboard is all departed from the axle center of two described the first running rollers, and is partial to respectively the both sides of described skid mainboard.
Preferably, the two ends of described skid mainboard are also respectively arranged with secondary skid mechanism, described secondary skid mechanism comprises bearing, travel(l)ing rest and the second running roller, described bearing is installed on the two ends of described skid mainboard, described travel(l)ing rest is installed on described bearing by the first rotating shaft, and described the second running roller is installed on described travel(l)ing rest by the second rotating shaft.
Preferably, described bearing lays respectively at the both sides of described skid mainboard.
Preferably, the two ends of described skid mainboard are also provided with the respectively diving board of corresponding described secondary skid mechanism.
Preferably, one end of described diving board is installed on the two ends of described skid mainboard, and lays respectively at the both sides of described skid mainboard with described bearing, and the other end of described diving board props up described travel(l)ing rest by side.
By technique scheme, elevator door orienting lug provided by the invention, it designs by running roller, and tool has the following advantages compared to existing technology:
1. the rolling of running roller has effectively reduced the resistance of elevator door when operation, does not have the slider wear problem of quality of rubber materials;
2. effectively reduce elevator faults rate, guaranteed the safety performance of elevator operation, and this inventive principle and simple in structure, be easy to apply.

The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
According to Fig. 3 and 4, elevator door orienting lug provided by the invention, comprises skid mainboard 11' and is installed on the main skid mechanism on skid mainboard 11'; Main skid mechanism comprises running roller seat 21 and is installed on the first running roller 22 on running roller seat 21.
The quantity of main skid mechanism is two groups and to be evenly distributed on skid mainboard 11' upper, and Mei Zuzhu skid mechanism includes running roller seat 21 and is installed on the first running roller 22 on running roller seat 21; Two running roller seats 21 lay respectively at the both sides of skid mainboard 11'; The line of centers of skid mainboard 11' is all departed from the axle center of two the first running rollers 22, and the both sides of being partial to respectively skid mainboard 11'.
The two ends of skid mainboard 11' are also respectively arranged with secondary skid mechanism, pair skid mechanism comprises bearing 23, travel(l)ing rest 25 and the second running roller 26, bearing 23 is installed on the two ends of skid mainboard 11', travel(l)ing rest 25 is installed on bearing 23 by the first rotating shaft 24 and take the first rotating shaft 24 and as axle center, carries out respective angles rotation, and the second running roller 26 is installed on travel(l)ing rest 25 by the second rotating shaft 32 and take the second rotating shaft 32 and as axle center, carries out respective angles rotation; The bearing 23 at skid mainboard 11' two ends lays respectively at the both sides of skid mainboard 11', by this design, makes the first running roller 22 of the main skid mechanism of midway location be partial to all the time the center of elevator door axis in service.Wherein, the first running roller 22 and the second running roller 26 preferentially select nylon wheel that fastness to rubbing is good and highly polished to improve the first running roller 22 and the second 26 life-spans of running roller, and reduce the friction force between the first running roller 22 and the second running roller 26 and the guide groove of sill as far as possible, but specifically do not limit, can carry out multiple choices according to actual conditions.
On skid mainboard 11', be also provided with the respectively diving board 31 of corresponding secondary skid mechanism, one end of diving board 31 is installed on the two ends of skid mainboard 11', and lays respectively at the both sides of skid mainboard 11' with bearing 23, and the other end of diving board 31 props up travel(l)ing rest 25 by side.The object that diving board 31 is set is by travel(l)ing rest 25 is applied to lateral pressure, make second running roller 26 at skid mainboard 11' two ends eccentric to the both sides of skid mainboard 11' respectively, thereby the first running roller 22 that makes skid mainboard 11' midway location is partial on the axis of elevator door operation all the time, has effectively guaranteed elevator traveling comfort.
Elevator door orienting lug provided by the invention, it designs by running roller, the rolling of running roller has effectively reduced the resistance of elevator door when operation, due to the slide block of application of rubber material not, therefore, there is not slider wear problem, effectively reduce elevator faults rate, guaranteed the safety performance of elevator operation, and this inventive principle and simple in structure, be easy to apply.
To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.
