Abstract
The present invention relates to a kind of common hand strap tensioning device, relate to handrail and truss, comprise that one is fixedly connected on the open slot that Open Side Down on the truss, hang in the described open slot and be connected with transversely movable triangle flat plate, described triangle flat plate and one can drive its horizontal linear moving apparatus that transverse translation takes place and be connected, described in addition triangle flat plate is provided with the arc roller set, described handrail is stretched on the roller set, then know thus, control by horizontal linear moving apparatus, can realize the side travel of triangle flat plate, promptly guarantee to be arranged at the arc roller set tensioning handrail all the time on the triangle flat plate, guarantee the smooth running of handrail effectively.
Description
Technical field
The present invention relates to a kind of parts that are used for staircase, especially a kind of common hand strap tensioning device.
Background technology
For footway conveyers such as staircases, for making the handrail smooth running, generally all to be provided with one can the tensioning handrail tightening device, but, the general out of reach requirement of the tightening device that prior art adopted, thus cause the operation of handrail not steady, even can't move.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of common hand strap tensioning device is provided, thereby guarantee handrail in tension all the time, promptly handrail can move reposefully.
A kind of common hand strap tensioning device, relate to handrail and truss, comprise that one is fixedly connected on the open slot that Open Side Down on the truss, hang in the described open slot and be connected with transversely movable triangle flat plate, described triangle flat plate and one can drive its horizontal linear moving apparatus that transverse translation takes place and be connected, described in addition triangle flat plate is provided with the arc roller set, and described handrail is stretched on the roller set.
Described horizontal mobile device comprises that an end is captiveed joint with triangle flat plate, the other end passes movable pull bar of placing of truss and the nut that is threaded with the pull bar movable end.
According to above technical scheme, can realize following beneficial effect:
1. owing to the invention provides a kind of hand rail tension device, when then using, control by horizontal linear moving apparatus, can realize the side travel of triangle flat plate, promptly guarantee to be arranged at the arc roller set tensioning handrail all the time on the triangle flat plate, guarantee the smooth running of handrail effectively.
2. horizontal linear moving apparatus of the present invention comprise a pull bar and with pull rod screw bonded assembly nut, then by the turn nut, thereby realize the left and right sides translation of pull bar, promptly realized the left and right sides translation of the triangle flat plate of captiveing joint with pull bar, thereby guarantee to be arranged on roller set on the triangle flat plate, that be positioned at handrail below tensioning handrail all the time, guarantee the smooth running of handrail effectively.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Explain technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figure 1, a kind of common hand strap tensioning device, relate to handrail 1 and truss 2, comprise that one is fixedly connected on the open slot 5 that Open Side Down on the truss 2, hang in the described open slot 5 and be connected with transversely movable triangle flat plate 3, described triangle flat plate 3 and one can drive its horizontal linear moving apparatus that transverse translation takes place and be connected, described in addition triangle flat plate 3 is provided with arc roller set 6, described handrail 1 is stretched on the roller set 6, and described horizontal mobile device comprises that an end captives joint with triangle flat plate 3, the other end passes truss 2 movable pull bars of placing 41 and the nut 42 that is threaded with pull bar 41 movable ends.
In addition, horizontal linear moving apparatus of the present invention be not limited to pull bar and with pull rod screw bonded assembly nut, the version that it can also adopt other taken place straight line to move.
