A kind of trackless translation door bottom girder directive wheel
Technical field
The utility model relates to translation door part field, relates in particular to a kind of trackless translation door bottom girder directive wheel.
Background technology
Door is the important component part of building circumference, and common door comprises that retractable door, rail translation door, trackless translation door, double fan horizontal drawing door realize sealing and the unlatching of enclosing boundary, to reach the object of enclosing boundary's security control.For needs attractive in appearance and that coordinate, trackless translation door replaces traditional translation door gradually, is employed more and more widely.Translation door door leaf consists of doorframe (claiming again bound edge) and door-plate.According to translation door doorframe, divide three kinds, the one, aluminium alloy extrusions translation door doorframe (being called for short aluminium horizontal sliding door), the 2nd, stainless steel translation door doorframe (being called for short stainless steel translation door), the 3rd, galvanized steel plain sheet translation door doorframe (be called for short zinc-plated translation door, claim again simple door).
Along with scientific and technological development, trackless translation door is applied to the occasions such as factory, school more and more.In prior art, be all generally, on trackless translation door bottom girder, directive wheel is installed, translation door is moved by gear driven tooth bar, thereby realizes the movement of translation door directive wheel.Wheel design is in the market complicated, in long-term use procedure, weares and teares more serious, causes maintenance cost to improve.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of trackless translation door bottom girder directive wheel is provided.
The utility model is to be achieved through the following technical solutions:
A kind of trackless translation door bottom girder directive wheel, comprise and be arranged on the panel of bottom girder end and be arranged on the pole on panel, described pole is provided with screwed hole, described pole is connected with support bar, described support bar is used for connecting guide wheel units, described guide wheel units is provided with directive wheel by rotating shaft, and described directive wheel external surface is coated with wearing layer.
As preferably, described wearing layer is chromium coating or nickel coating.
As preferably, the thickness of described wearing layer is 3mm.
As preferably, described directive wheel is provided with self-locking mechanism.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, and single directive wheel is set can meet the demands, and increase wearing layer on directive wheel simultaneously, improve its wear-resisting effect.
