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
Bottom roller joint face in upper bank base plate and the link plate of existing elevator landing door is plane, in knockout process link plate be easy to from come off in bank, thereby cause relevant accident.Especially in the time that reply passenger is clashed into, can not 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 upper bank base plate 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 upper change gear and the bottom roller that arrange on it, on the rolling surface of described upper change gear, be arranged with limited impression along circumferential hoop, the top of described guide rail is provided with stretches into described limited impression upper convex portion with matching, it is characterized in that: the bottom of described guide rail is provided with horizontally disposed fitting surface, the rolling surface of described bottom roller and described fitting surface are slidingly fitted, the lower end of described guide rail is provided with from the below of described bottom roller extends also the upwards bending edges of bending towards described link plate, described bending edges surrounds and forms positioning groove below described bottom roller, described bottom roller is arranged in described positioning groove, the upper surface height of described bending edges is higher than the lower surface of described bottom roller.
Preferably, the lower surface height of described bottom roller is higher than the bottom land of described positioning groove.
Preferably, the cross sectional shape of described limited impression is arc, and the cross sectional shape of described upper convex portion is arc.
Further, the cross sectional shape of described upper convex portion is semicircular arc, and the arc radius of described limited impression is greater than or equal to the arc radius of described upper convex portion.
Owing to adopting technique scheme, the elevator landing door of anti-collision and dropping-proof of the present utility model has improved the structure of upper bank base plate, utilize the bending edges of guide rail lower end to the bottom roller location in link plate, in knockout process, bending edges is limited in bottom roller in positioning groove, prevent that link plate from coming off in knockout process, improved the safety of elevator landing door.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1, an elevator landing door for anti-collision and dropping-proof, comprises bank base plate 1, guide rail 2 and link plate 3, and guide rail 2 is for being horizontally disposed with, link plate 3 is slidably mounted on described guide rail 2 by the upper change gear 4 and the bottom roller 5 that arrange on it, and bottom roller 5 is fixed on link plate 3 by roller mount 6.On the rolling surface of upper change gear 4, be arranged with limited impression 41 along circumferential hoop, the top of guide rail 2 is provided with the upper convex portion 21 that stretches into limited impression 41, and limited impression 41 and upper convex portion 21 match.Wherein, upper bank base plate 1 and guide rail 2 are formed in one, and guide rail 2 is formed by the direct bending of upper bank base plate 1.The bottom of guide rail 2 is provided with horizontally disposed fitting surface 22, the rolling surface of bottom roller 5 and fitting surface 22 are slidingly fitted, the lower end of guide rail 2 is provided with from the below of bottom roller 5 extends also the upwards bending edges 7 of bending towards link plate 3, described bending edges 7 surrounds and forms positioning groove 8 below described bottom roller 5, and bottom roller 5 is arranged in described positioning groove 8.Wherein, bending edges 7 is arranged in the gap of bottom roller 5 and link plate 3, and the upper surface height of bending edges 7 is higher than the lower surface of bottom roller 5.
Wherein, the cross sectional shape of limited impression 41 is arc, and the cross sectional shape of upper convex portion 21 is semicircular arc, and the arc radius of described limited impression 41 is greater than or equal to the arc radius of described upper convex portion 21.
In the present embodiment, the lower surface height of bottom roller 5 is higher than the bottom land of positioning groove 8, and bottom roller 5 in vacant state, and also has gap with respect to positioning groove 8 between normal bottom roller 5 in service and bending edges 7.When clashing into, when shock strength is slighter, the upper convex portion 21 of guide rail 2 and the mating reaction of upper change gear 4 can alleviate to a certain extent impact in knockout process.When shock strength is larger, because bottom roller 5 is owing to being subject to the restriction of bending edges 7, be all positioned at all the time positioning groove 8, thereby avoided causing the phenomenon that link plate 3 comes off from upper bank base plate 1 to occur because clashing into.Therefore, elevator landing door of the present utility model has the function of anti-collision and dropping-proof.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
