Description
Technical field
The utility model relates to elevator landing door, especially a kind of elevator landing door of anti-collision and dropping-proof.
Background technology
The upper bank base plate of existing elevator landing door and the roller joint face in link plate are plane, in knockout process link plate be easy to from come off in bank, thereby cause relevant accident.Especially when reply passenger is clashed into, cannot guarantee that the roller of layer door gear link plate in knockout process can not deviate from guide rail, thereby layer door can be rushed open in the scope of the power that can apply a people, elevator accident easily occurs.For this situation, need at present the structure of improving elevator landing door badly, to prevent that link plate from coming off, thereby reduce the accident causing because of door system reason.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of elevator landing door of anti-collision and dropping-proof.
For achieving the above object, the utility model by the following technical solutions:
A kind of elevator landing door of anti-collision and dropping-proof, comprise bank base plate, guide rail and link plate, described link plate is slidably mounted on described guide rail by the roller arranging on it, on the rolling surface of described roller, along circumferential hoop, be arranged with circular groove, it is characterized in that: the bottom of described guide rail is provided with protuberance under the circular arc raising up, under described circular arc, protuberance matches with described circular groove; The top of described guide rail is provided with the circular arc upper convex portion to lower convexity, and described circular arc upper convex portion snaps in the circular groove of upper end of described roller, between the circular groove of the upper end of described circular arc upper convex portion and described roller, has gap; Described roller clip is under described circular arc upper convex portion and described circular arc between protuberance and only can rollably be supported on along the length direction of described guide rail under described circular arc on protuberance.
Preferably, described upper bank base plate and described guide rail are formed in one, and under described circular arc upper convex portion and described circular arc, protuberance is formed by the direct bending of described guide rail respectively.
Preferably, on described link plate, the length direction along described guide rail is arranged at intervals with a plurality of described rollers.
Owing to adopting technique scheme, the elevator landing door of anti-collision and dropping-proof of the present utility model is by adopting the roller of circular groove to be rollably supported under the circular arc of guide rail on protuberance, and then to the axial location of circular arc roller and upper-lower position, carry out spacing by the circular arc upper convex portion of guide rail, roller is clipped in wherein and only and can rolls along the length direction of guide rail by protuberance under the circular arc of guide rail and circular arc upper convex portion, thereby in knockout process, can prevent that roller from departing from from guide rail, and then prevent that link plate from coming off in knockout process, improved the safety of elevator landing door.
Accompanying drawing explanation
Fig. 1 is the schematic side view of elevator landing door of the present utility model.
Fig. 2 is that the master of the link plate in the utility model looks schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1, a kind of elevator landing door of anti-collision and dropping-proof, comprises bank base plate 1, guide rail 2 and link plate 3.
Link plate 3 is slidably mounted on guide rail 2 by the roller 4 arranging on it, on the rolling surface of roller 4, along circumferential hoop, is arranged with circular groove 41.
The bottom of guide rail 2 is provided with protuberance 21 under the circular arc raising up, and under circular arc, protuberance 21 matches with the circular groove 41 of roller 4.The top of guide rail 2 is provided with the circular arc upper convex portion 22 to lower convexity, and circular arc upper convex portion 22 just snaps in the circular groove 41 of upper end of roller 4.Stuck for fear of roller 4, between the circular groove 41 of the upper end of circular arc upper convex portion 22 and roller 4, there is gap.
Roller 4 is clipped under circular arc upper convex portion 22 and circular arc between protuberance 21 and only can be rollably supported on along the length direction of guide rail 2 under circular arc on protuberance 21.In the present embodiment, as shown in Figure 2, the length direction along guide rail 2 on link plate 3 is arranged at intervals with two rollers 4, and in order to make, rolling is more smooth, vibrations are less certainly, and the quantity of roller 4 also can be more than two.A plurality of rollers 4 preferably even interval are arranged.
For the ease of processing, upper bank base plate 1 and guide rail 2 are formed in one, and under circular arc upper convex portion 22 and circular arc, protuberance 21 is formed by the direct bending of guide rail 2 respectively.
Because roller 4 is sandwiched under circular arc upper convex portion 22 and circular arc between protuberance 21, when clashing into, because above-below direction and the axial direction of roller 4 is all restricted, thereby avoided causing roller 4 derailings to cause the phenomenon that link plate 3 comes off to occur because clashing into.Therefore, elevator landing door of the present utility model has the function of anti-collision and dropping-proof, and safety is higher.
