Abstract
The utility model discloses an anti-falling device for an elevator. The anti-falling device comprises an elevator door (1) and an elevator car door sill (2) arranged below the elevator door (1); a bottom plate (3) is arranged below the elevator car door sill (2); an elastic plate (4) is arranged between the elevator car door sill (2) and the bottom plate (3); a limiting plate (5) is arranged at the rear part of the elevator car door sill (2); a propping device (6) is arranged at the rear part of the elastic plate (4); and a baffle (7) is arranged on the lower side of the elevator door (1). Compared with the prior art, the utility model has the advantage that the elastic plate and the propping device are arranged below the elevator car door sill, and the baffle is arranged at the lower part of the elevator door, so that during the opening and the closing of the elevator door, the popup and the withdrawal of the elastic plate can be automatically realized without additional transmission devices. The elastic plate can better shield gaps by adopting the manner of regular arrangement of special elastic plates; and meanwhile, the popup and the withdrawal of the elastic plate can enabled to be more stable, so that the unnecessary abrasion is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of anti-dropping apparatus, particularly a kind of elevator anti-dropping apparatus.
Background technology
Shanghai Mitsubishi Elevator Co. Ltd has applied for that in 2007 a key name is the patent (patent No.: 200620045532.8) of elevator protection brush.This patent disclosure a kind of elevator protection brush, by on lift car door or entrance hall door, bristle being set, fill the slit between lift car door and the entrance hall door, thereby prevent that small articles from falling into elevator by the slit.This set is simple in structure, but owing to have the slit between the bristle, can not play the effect of complete filling, and some volumes are little but article that quality is bigger still can pass layers of brush bristles falls into elevator.Because the long-term friction between bristle and the door can cause bristles bend and damage, lose safeguard function simultaneously.
The utility model content
The purpose of this utility model is, provides a kind of elevator anti-lost natural and graceful device; The utlity model has the slit of effectively blocking between lift car door and the entrance hall door, not fragile, the characteristics of long service life.
The technical solution of the utility model: a kind of elevator bleeds off dropping control device, comprise elevator door and the lift car door of being located at the elevator door below, lift car door below is provided with base plate, be provided with diving board between lift car door and the base plate, the rear portion is provided with positioning plate, the diving board rear portion is provided with device for ejecting, and the elevator door downside is provided with baffle plate.
In the aforesaid elevator anti-dropping apparatus, device for ejecting is a spring, and an end of spring is connected with diving board, and the other end is connected with positioning plate.
In the aforesaid elevator anti-dropping apparatus, device for ejecting can also be shell fragment, and shell fragment one end is fixed on the upper surface of base plate, and the other end links to each other with the rear portion of diving board.
In the aforesaid elevator anti-dropping apparatus, diving board is that the benchmark symmetry closely is provided with the elevator door center line.
In the aforesaid elevator anti-dropping apparatus, diving board is divided into two parts, part away from the elevator door center line is the rectangular pyramid type, is the right-angled trapezium of hypotenuse at downside near the cross section of the part of diving board center line, and the angle of the angle of inclined-plane and horizontal surface and rectangular pyramid upper surface and horizontal surface is identical.
In the aforesaid elevator anti-dropping apparatus, diving board is divided into two parts, can also be wedge away from the partial shape of elevator door center line, can also be cuboid near the shape of the part of diving board center line.
Compared with prior art, the utility model is put diving board and device for ejecting by dividing at the lift car door, in the elevator door bottom baffle plate is set, and can realize the ejection of diving board and withdrawal automatically and need not to add devices such as transmission in elevator door opening and closing process.Adopt the method for special-shaped diving board regular arrangement can make diving board can better block the slit, make the ejection of diving board and withdrawal process more stable simultaneously, reduce unnecessary wearing and tearing, increase the service life.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment of the present utility model:
Embodiment 1.The elevator anti-dropping apparatus, constitute as shown in Figures 1 to 3, comprise elevator door 1 and the lift car door 2 of being located at elevator door 1 below, lift car door 2 belows are provided with base plate 3, be provided with diving board 4 between lift car door 2 and the base plate 3, the rear portion is provided with positioning plate 5, and diving board 4 rear portions are provided with device for ejecting 6, and elevator door 1 downside is provided with baffle plate 7.Device for ejecting 6 is a spring, and an end of spring is connected with diving board 4, and the other end is connected with positioning plate 5.Diving board 4 is a benchmark symmetry close arrangement with the elevator door center line.Diving board 4 is divided into two parts, is the rectangular pyramid type away from the part of elevator door center line, is the right-angled trapezium of hypotenuse at downside near the cross section of the part of diving board center line, and the angle of the angle of inclined-plane and horizontal surface and rectangular pyramid upper surface and horizontal surface is identical.
Embodiment 2.The elevator anti-dropping apparatus, constitute as Fig. 1, Fig. 2 and shown in Figure 4, comprise elevator door 1 and the lift car door 2 of being located at elevator door 1 below, lift car door 2 belows are provided with base plate 3, be provided with diving board 4 between lift car door 2 and the base plate 3, the rear portion is provided with positioning plate 5, and diving board 4 rear portions are provided with device for ejecting 6, and elevator door 1 downside is provided with baffle plate 7.Device for ejecting 6 is a shell fragment, and shell fragment one end is fixed on the upper surface of base plate 3, and the other end links to each other with the rear portion of diving board 4.Diving board 4 is a benchmark symmetry close arrangement with the elevator door center line.Diving board 4 is divided into two parts, is wedge away from the partial shape of elevator door center line, near the cuboid that is shaped as of the part of diving board center line.
