Description
Technical field
The present invention relates to a kind of movable escalator movable support mechanism, in movable escalator, belong to movable escalator technical field.
Background technology
In movable escalator technical field, when wheel in the past needs static, be all need people first brake to be slammed when upper staircase, or people directly get on after utilize the body weight of people to make wheel stationary.These two kinds of modes are owing to being all on people after staircase, and wheel is stressed, so very large to the infringement of wheel, first kind of way operation is more loaded down with trivial details, the second way is owing to being utilize the body weight of people to reach the effect of fixing staircase, and wheel can still be puted forth effort, so can be more dangerous.
Summary of the invention
After the technical problem to be solved in the present invention is to provide the upper staircase of a kind of people, wheel can be liftoff unsettled, and wheel is not stressed, and avoids the movable escalator movable support mechanism of the unfixing danger brought of the loss of wheel and wheel.
In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide a kind of movable escalator movable support mechanism, it is characterized in that: comprise the lever assembly and spring assembly that are connected to each other;
Lever assembly comprises lever, and lever one end is connected with spring assembly, the lever other end connect wheel, lever with fulcrum support plate for fulcrum is welded on staircase;
Spring assembly comprises outer jointing jacket, and outer jointing jacket is welded with staircase by support plate, and outer jointing jacket also connects lever; Spring protection stay pipe is with being located in inside outer jointing jacket, and spring protection stay pipe lower end and fulcrum support plate are weldingly connected; Spring retainer stay pipe is with being located in inside spring protection stay pipe, and spring retainer stay pipe lower end connects below support plate, and below support plate is positioned at bottom fulcrum support plate; Be provided with spring between spring protection stay pipe and spring retainer stay pipe, spring protection cap is positioned at spring top and is connected with spring retainer stay pipe, outer jointing jacket linking springs protective cap and spring retainer stay pipe.
Preferably, described lever one end is connected with described outer jointing jacket by connection side's plate.
Preferably, described outer jointing jacket is connected with described spring protection cap, spring retainer stay pipe screw thread respectively.
Preferably, stopper slot for spacing described spring is provided with on described fulcrum support plate with inside spring protection stay pipe junction.
When movable escalator provided by the invention uses, after the upper staircase of people, spring downward, lift on the wheel on lever assembly, wheel can be liftoff unsettled, and below support plate will be supported in ground, adds the safety of people on movable escalator, reduce the loss to wheel, make the use of movable escalator succinctly more convenient.
Device provided by the invention overcomes the deficiencies in the prior art, simple and compact for structure, with low cost, by being fixed on mechanism on staircase and lever principle, after the upper staircase of guarantor, wheel can be liftoff unsettled, wheel is not stressed, avoids loss and the unfixing danger brought of wheel of wheel.
Accompanying drawing explanation
Fig. 1 is movable escalator movable support mechanism provided by the invention front view;
Fig. 2 is movable escalator movable support mechanism side view provided by the invention.
Detailed description of the invention
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 1 and Fig. 2 is respectively movable escalator movable support mechanism's front view provided by the invention and lateral view, and described movable escalator movable support mechanism comprises the lever assembly 1 and spring assembly 2 that are connected to each other.
Lever assembly 1 comprises lever 11 and fulcrum support plate 13, and lever 11 one end is connected with spring assembly 2 by connection side's plate 12, lever 11 other end connect wheel 14, lever 11 with fulcrum support plate 13 for fulcrum is welded on staircase.
Spring assembly 2 is made up of outer jointing jacket 21, spring protection stay pipe 22, spring retainer stay pipe 23, spring protection cap 24 and spring 25.Outer jointing jacket 21 is welded with staircase by support plate 26, and lever 11 one end is connected with outer jointing jacket 21 by connection side's plate 12.Spring protection stay pipe 22 is coaxially arranged on inside outer jointing jacket 21, and spring protection stay pipe 22 lower end and fulcrum support plate 13 are weldingly connected.Spring retainer stay pipe 23 is coaxially arranged on inside spring protection stay pipe 22, and spring retainer stay pipe 23 lower end connects below support plate 221, and below support plate 221 is positioned at bottom fulcrum support plate 13.Spring 25 is housed between spring protection stay pipe 22 and spring retainer stay pipe 23; spring protection cap 24 is positioned at spring 25 top and is connected with spring retainer stay pipe 23; outer jointing jacket 21 is connected with spring protection cap 24, spring retainer stay pipe 23 screw thread respectively; convenient replacement spring 25, also makes this mechanism be suitable for the staircase of Different Weight by replacing spring.
A stopper slot 131 is opened, for limit spring 25 on fulcrum support plate 13 with inside spring protection stay pipe 22 junction.Spring retainer stay pipe 23 can not double swerve for restraining spring 25.Below support plate 221 is for when people stands upper staircase, and after spring 25 presses down, lift on the wheel 14 on lever assembly 1, below support plate 221 will be supported in ground.
When movable escalator provided by the invention uses, after the upper staircase of people, spring downward, lift on the wheel on lever assembly, wheel can be liftoff unsettled, and below support plate will be supported in ground, adds the safety of people on movable escalator, reduce the loss to wheel, make the use of movable escalator succinctly more convenient.
Device provided by the invention overcomes the deficiencies in the prior art, simple and compact for structure, with low cost, by being fixed on mechanism on staircase and lever principle, after the upper staircase of guarantor, wheel can be liftoff unsettled, wheel is not stressed, avoids loss and the unfixing danger brought of wheel of wheel.
