Description
Technical field
The utility model is related to technical field of elevator equipment, specifically disclose a kind of elevator door slide block assembly.
Background technology
Chinese elevator industry experienced a high-speed development period at past 10 years, and the sustained production of elevator increases, Nian Zeng
20% or so, China successively becomes elevator market maximum in the world, elevator manufacture and using state long rate.
And in face of elevator safety Frequent Accidents in recent years, elevator door sliding block is easy to wear to lead to noise occur, influences passenger and multiplies
Ladder impression causes the rate of complaints to be continuously increased.This elevator door sliding block can effectively solve the problems, such as that easy to wear and noise is big, meets simultaneously
National standard.
Retrieval at present existing patented technology, such as it is presently disclosed application No. is 201420368293.4 utility model patent
A kind of elevator door sliding block, wherein door sliding block designs for H-type, each side opens up there are one groove, when sliding block works, mainly
It is sliding block two sides and wall friction in sill sliding slot.However, the elevator door sliding block two sides of the utility model patent are slided with sill
It is contacted during wall friction for face in slot, it thus can the defects of big, easy to wear and noise is big there are frictional force.
Invention content
The purpose of the utility model is to overcome defects in the prior art, provide a kind of superior, wearability
Height, manufacturing process are simple, operation noise is small and lower-cost elevator door slide block assembly.
The utility model is realized in this way：A kind of elevator door slide block assembly is connected including door sliding block axis, with door sliding block axis
And the door slider body in sill sliding slot, it is characterised in that：The door slider body includes left side, right side, front side
The curved surface of smooth protrusion outside with respect to surrounding, described centered on the shape difference of face and trailing flank, the left side and right side
The shape of left side and right side is symmetrical, the left side, right side the inner wall point contact with the sill sliding slot respectively,
The middle part of the door slider body is equipped with the cavity for connecting the door sliding block axis lower part, and the door sliding block axis lower part is located at the type
It is clearance fit between intracavitary and the door sliding block axis lower part and the cavity.
The leading flank and trailing flank are respectively plane.
The lower sides of the door sliding block axis are equipped with annular groove, and the cavity is cylindrical cavity, the cavity
Inner wall is equipped with 1 ~ 6 anticreep boss, and the anticreep boss is limited in the annular groove by the annular groove.
The leading flank and the width of trailing flank are respectively smaller than the width of left side and right side；The left side, right side
The height in face, leading flank and trailing flank is equal.
The beneficial effects of the utility model are：The left side and right side of the door slider body are curved surface, door sliding block
There is cavity in the centre of ontology, and entire door slider body is sunk in sill sliding slot, is point contact with sill sliding slot inner wall, and entire
It is always point contact in door slider body operational process, the utility model runs small noise, easy production and processing simple in structure and peace
Dress, wearability are good, and service life is long.
