Description
Technical field
The utility model is related to a kind of step axles suitable on escalator step chain, refer in particular to a kind of versatile and valency
The cheap hollow step axle of lattice.
Background technology
With the fast development and application of escalator, the competition of escalator manufacturing firm is more and more fierce.Each staircase
Manufacturer releases the product of oneself one after another, and the step axle form of a variety of different structures occurs, some of which step axle knot
Structure is partially complicated also uneconomical, and versatility is extremely low, it is impossible to meet the requirement of most different manufacturers.
Utility model content
The utility model aim is provided a kind of versatile and cheap for overcome the deficiencies in the prior art
Hollow step axle.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of hollow step axle, including central hollow
Axis；Symmetrical first resilient key there are two being set on the central hollow axis；It is located on the central hollow axis outside the first resilient key
Side is arranged with axle sleeve respectively；The axle sleeve is located at dowel hole one side equipped with gasket, and opposite side is equipped with spring, and gasket one side
It is positioned and fixed by the bolt for being inserted into the first resilient key；Axle bush sleeve is equipped between the axle sleeve and gasket；The central hollow axis two
End is respectively equipped with the second resilient key；The central hollow axis both sides are inserted with axis pin respectively, and axis pin is by being inserted into the second resilient key
Bolt fix；Sleeve is arranged on the axis pin exposed part, and main wheel is arranged on sleeve；The main wheel both sides are set respectively
There is the inner plate being arranged in parallel through axis pin；The outer plate through axis pin is respectively equipped on the outside of the inner plate.
Preferably, fixed on the outside of the axis pin by baffle ring.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Hollow step axle described in the utility model takes hollow design, as long as axis outer diameter and both ends aperture and total length ruler
Very little work is corresponding to be changed, with regard to that can meet the requirement of most different manufacturers；Hollow step axle described in this practicality is at low cost
It is honest and clean, versatile, simple in structure and easy to process.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the structure diagram of hollow step axle described in the utility model.
Attached drawing 2 is the structure diagram of central hollow axis described in the utility model.
Wherein：1st, central hollow axis；2nd, the first resilient key；3rd, axle sleeve；4th, gasket；5th, spring；6th, axle bush sleeve；7th, axis pin；
8th, the second resilient key；9th, sleeve；10th, main wheel；11st, inner plate；12nd, outer plate；13rd, baffle ring.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Attached drawing 1-2 is hollow step axle described in the utility model, including central hollow axis 1；On the central hollow axis 1
If there are two symmetrical first resilient keys 2；It is located at 2 outside of the first resilient key on the central hollow axis 1 and is arranged with axle sleeve respectively
3；The axle sleeve 3 is located at 2 one side of the first resilient key equipped with gasket 4, and opposite side is equipped with spring 5, and 4 one side of gasket is by insertion first
The bolt positioning of resilient key 2 is fixed；Axle bush sleeve 6 is equipped between the axle sleeve 3 and gasket 4；1 both ends of the central hollow axis difference
Equipped with the second resilient key 8；1 both sides of central hollow axis are inserted with axis pin 7 respectively, and axis pin 7 is by being inserted into the second resilient key 8
Bolt is fixed；Sleeve 9 is arranged on 7 exposed part of axis pin, and main wheel 10 is arranged on sleeve 9；10 both sides of main wheel
It is respectively equipped with the inner plate 11 being arranged in parallel through axis pin 7；11 outside of inner plate is respectively equipped with the outer plate through axis pin 7
12；7 outside of axis pin is fixed by baffle ring 13.
It is more with regard to that can meet as long as being changed in use, outer diameter and internal diameter and the overall length dimension work of central hollow axis 11 are corresponding
The requirement of the different manufacturers of number.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Hollow step axle described in the utility model takes hollow design, as long as axis outer diameter and both ends aperture and total length ruler
Very little work is corresponding to be changed, with regard to that can meet the requirement of most different manufacturers；Hollow step axle described in this practicality is at low cost
It is honest and clean, versatile, simple in structure and easy to process.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
