Description
Technical field
The utility model relates to a kind of elevator landing door, particularly a kind of elevator landing door of impact resistance.
Background technology
Include bank base plate in elevator landing door, be articulated in the layer door hanging plate in the rail sections of bank base plate and layer door, wherein layer door hanging plate does straight reciprocating motion along rail sections, and the upper end of layer door fixes with corresponding layer door hanging plate.
Elevator landing door collides when layer door is subject to external force in actual use, lift or the situation such as inclination time, in order to the rail sections of preventing layer door strap from upper bank base plate comes off, so that generation use safety accident.As shown in Figure 1, existing above-mentioned layer door hanging plate 2 also has additional spacing gear wheel 14, axle section 16 activity of spacing gear wheel 14 penetrates in skewed bar hole 15 that layer door hanging plate 2 is offered in advance, once spacing gear wheel 14 can be locked with layer door hanging plate phase nut 17 after adjusting position, then formed in the bottom of upper bank base plate 1 and coordinate above-mentioned spacing gear wheel 14 and level is carried out or/and vertical direction is carried out spacing limit sliding chutes 5 to this spacing gear wheel 14.Because limit sliding chutes is all carried out spacing to the side-to-side movement direction of spacing gear wheel and up-and-down movement direction in said structure, namely above-mentioned layer door hanging plate all can only do trace adjustment in side-to-side movement direction and up-and-down movement direction in space, thus also just improve the anti-collision performance of layer door, layer door above-mentioned under external force also cannot by lift, the safety in operation of whole elevator landing door can promote.But the elevator landing door of said structure design still has following technical matters: first, owing to layer door hanging plate adds additional limiting block wheel assembly, this can make the piece-production cost of layer door hanging plate be increased sharply undoubtedly; Because spacing gear wheel is fixed in skewed bar hole by mechanical interlocking modes such as nuts in next said structure, consider during elevator car systems runs the operational vibration that inherently there is trace, to such an extent as to above-mentioned in spacing gear wheel and the mechanical interlocking place of layer door hanging plate easily occur after a long time use being connected situations such as loosening, thus buried potential safety hazard to the operation of whole elevator landing door.Therefore, be necessary to do further technological improvement to the elevator landing door in above-mentioned.
Utility model content
The purpose of this utility model is the elevator landing door providing a kind of impact resistance in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the elevator landing door of a kind of impact resistance designed by the utility model, comprise bank base plate and layer door hanging plate, on described bank base plate waist location on be formed with the rail sections that vertical section is horizontal serpentine, the bottom position of described rail sections is connected with the bending sheet metal of vertical section in horizontal " Contraband " shape, and both surround limit sliding chutes jointly, described layer door hanging plate has additional the first punching, its punching clout is connected with the edge, hole of side, and be punched and be shaped to the first positive stop hook, first hook head portions of this first positive stop hook enters in the guide-track groove of the rail sections of above-mentioned upper bank base plate, and be free-running fit shape with rail sections, described layer door hanging plate also has additional the second punching, its punching clout is connected with the edge, hole of side equally, and be punched and be shaped to the second positive stop hook, this second positive stop hook is positioned at above-mentioned limit sliding chutes, clearance distance between its end face and the upper edge of limit sliding chutes is 0.5 ~ 2 ㎜, the upwards extension of its second hook head portions and limit sliding chutes end overlaps spacing in the horizontal direction in space.
The elevator landing door of above-mentioned a kind of impact resistance, by one-body molded first positive stop hook and the second positive stop hook on layer door hanging plate in its structure, and the first hook head portions of the first above-mentioned positive stop hook enters in the guide-track groove of corresponding upper bank base plate, the second above-mentioned positive stop hook entirety is positioned at corresponding limit sliding chutes.Namely relative to upper bank base plate, above-mentioned layer door hanging plate can only make the adjustment of trace on its side-to-side movement direction and up-and-down movement direction, thus makes elevator landing door provided by the utility model possess impact resistance function; Simultaneously, be the structure of integral type just because of the first positive stop hook in above-mentioned and the second positive stop hook and layer door hanging plate main body, therefore the globality of layer door hanging plate structure is strong, in long-time use procedure, also can not occur because of outer application force two situation reducing structural stability.
As further technological improvement, above-mentioned layer door hanging plate has additional be positioned at above-mentioned on the spacing gear wheel of limit sliding chutes of bank base plate, the concrete connection structure of this spacing gear wheel on layer door hanging plate is: described layer door hanging plate offers skewed bar hole, and the axle section of described spacing gear wheel is run through above-mentioned bar hole and locked by nut.In this Technological improvement plan, spacing gear wheel combines with the position limiting structure of upper bank base plate with first, second positive stop hook on above-mentioned middle layer door hanging plate with the position limiting structure of upper bank base plate, thus further improve the intensity of layer door hanging plate impact resistance in elevator landing door, the phenomenon occurring that layer door hanging plate comes off from upper bank base plate can be avoided to the full extent.
The elevator landing door of a kind of impact resistance that the utility model obtains, by the layer door hanging plate elevator door be articulated on upper bank base plate, there is very high impact resistance intensity in its structure, simultaneously also cannot by external force by lift, when therefore using in whole elevator device, its safety of structure is higher, thus the safety performance that can promote when whole elevator device runs, ensure the security of the lives and property that elevator ride.
