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 upper roller and the bottom roller arranging on it, it is characterized in that: described guide rail is formed by the bending that makes progress of the bottom of described upper bank base plate, described in the upper end edge of described guide rail, the extension of the length direction of upper bank base plate is provided with the upper rail with groove, described upper roller only can move along the length direction of described upper bank base plate and be arranged in described groove, the both sides of described groove are respectively arranged with the described upper roller of restriction along madial wall and the lateral wall of self axial motion, described in the lower end edge of described guide rail, the extension of the length direction of upper bank base plate is provided with lower guideway, and described bottom roller only can move along the length direction of described upper bank base plate and be arranged on the below of described lower guideway.
Preferably, described lower guideway is served as reasons described upper bank base plate through the flat guide that vertically bending forms, the cylinder roller of described bottom roller for rolling on described flat guide, and the outer circumference surface of described cylinder roller matches with described flat guide.Flat guide has limited cylinder roller upward movement, thereby prevents that upper roller from deviating from from the groove of upper rail, the danger of also just having avoided link plate to depart from from guide rail.
Preferably, the described lower guideway arc guide rail that described upper bank base plate forms through circular arc bending of serving as reasons, described bottom roller is the track roller with arc groove, the arc groove of described track roller upper end matches with described arc guide rail.Arc guide rail had both limited track roller upward movement, had also limited track roller and had moved vertically, thereby further prevented that link plate from coming off from guide rail.
Owing to adopting technique scheme, in upper bank base plate lower end, direct bending forms guide rail to the elevator landing door of anti-collision and dropping-proof of the present utility model, and at guide rail upper and lower side, upper rail and lower guideway are set respectively, by the upper roller of link plate only can be moved along the length direction of upper bank base plate and is arranged in the groove of upper rail, and then depart from from groove by the engagement limits upper roller of bottom roller and lower guideway, guarantee that link plate can not come off when clashing into from guide rail, has improved the safety of elevator landing door.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Embodiment mono-
Refer to Fig. 1 and Fig. 2, 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 upper roller 4 and the bottom roller arranging on it.
Guide rail 2 is formed by the bending that makes progress of the bottom of upper bank base plate 1, and on the upper end edge of guide rail 2, the length direction of bank base plate 1 extends and is provided with the upper rail 21 with groove 210, and upper roller 4 only can move along the length direction of upper bank base plate 1 and be arranged in groove 210.The both sides of groove 210 are respectively arranged with restriction upper roller along madial wall 211 and the lateral wall 212 of self axial motion.
On the lower end edge of guide rail 2, the extension of the length direction of bank base plate 1 is provided with lower guideway, and described bottom roller only can move along the length direction of upper bank base plate 1 and be arranged on the below of lower guideway.In the present embodiment, lower guideway is served as reasons upper bank base plate 1 through the flat guide 22 that vertically bending forms, the cylinder roller 5 of described bottom roller for rolling on described flat guide, and the outer circumference surface of cylinder roller 5 matches with flat guide 22.
In the present embodiment, as shown in Figure 2, the length direction along upper rail 21 on link plate 3 is arranged at intervals with two upper rollers 4.In order to make, rolling is more smooth, vibrations are less, and the quantity of upper roller 4 also can be more than two.A plurality of upper rollers 4 preferably even interval are arranged.Similarly, on link plate 3, the length direction along flat guide 22 is also arranged at intervals with two bottom rollers.
Elevator landing door middle guide 2 of the present utility model is by upper bank base plate 1 one bending and molding, simple in structure, easy to process.Due to upper roller 4 only can be in groove 210 along on the length direction of bank base plate 1 move, the madial wall 211 of groove 210 both sides and lateral wall 212 have limited the axial motion of upper roller 4, the motion that coordinates and limited upper roller 4 above-below directions of lower guideway and bottom roller, thereby when occurring to clash into, because above-below direction and the axial direction of roller 4 is all restricted, avoided causing upper 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.
Embodiment bis-
Refer to Fig. 3 and Fig. 4, the basic structure of the elevator landing door of the present embodiment is identical with embodiment mono-, difference is: the arc guide rail 23 that upper bank base plate 1 forms through circular arc bending of serving as reasons of lower guideway described in the present embodiment, described bottom roller is the track roller 6 with arc groove 61, and the arc groove 61 of track roller 6 upper ends matches with arc guide rail 23.
