Description
Technical field
This utility model relates to a kind of elevator landing door system, particularly open a kind of self-closing weight of elevator door.
Background technology
The self-closing power of current most of elevator door is all that the gravity utilizing weight is transformed, and realizes the self-closing of layer door by weight slide downward in weight guide pipe.The weight of elevator is particularly important for Lift car type elevator, and especially can hall door system be opened the door smoothly and be closed the door serves vital effect.On major part layer door gear, weight used all uses square steel to be made in the market, and processing cost and material cost are higher.
And if do not use square steel to make, by the weight often insufficient strength of the structure fabrications such as filling, there is certain potential safety hazard.The most presently disclosed patent: the self-closing weight of CN204224060U elevator door, the upper weight main body of its design is cavity body, and make weight reach the mode of predetermined weight for filling, the defect of this mode is that the weight main body loading implant is once by external force collision or erosion, weight body shell is caused to rupture, its implant will leak and cause weight weight not enough, so cause layer door cannot self-closing and door, produce certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of while meeting and ensureing personal effect and the performance closing weight, simple in construction, easily manufactured, and the self-closing weight of lower-cost elevator door.
This utility model is achieved in that a kind of self-closing weight of elevator door, including weight main body, weight guide, steel wire rope connector, described weight guide it is respectively fixed with around the two ends of described weight main body, it is characterized in that: described weight main body is in cuboid or cylindrical foundry goods, the inside of described weight main body is provided with built-in fitting, the two ends of described weight main body are stretched out at the two ends of described built-in fitting and wherein one end of built-in fitting is connected as a single entity with described steel wire rope connector, and described built-in fitting is chosen any one kind of them in reinforcing bar or sheet metal component；The two ends end face that two ends end face is plane or weight main body of described weight main body is provided with and convexes to form step.
When described built-in fitting is reinforcing bar, described steel wire rope connector is annular or reverse U shape or in screwed straight rod type.
When described built-in fitting is sheet metal component, described steel wire rope connector is provided with connecting hole.
Being provided with when convexing to form step in the middle of the two ends end face of described weight main body, described weight guide is fixed on around described projection.
Described weight guide is nylon guide or rubber guides, and described weight guide is fixed on the two ends of described weight main body by bolt nut.
The beneficial effects of the utility model are: simple in construction, reasonable in design, the structure that weight main body in prior art uses solid square steel is improved to one-part cast, make overall the simplifying the structure and diversification of weight so that the assembling in later stage is more the simplest and convenient.This utility model is overall reduces processing cost and material cost while ensureing self-closing effect.
