Abstract
The present invention relates to a kind of handrail strap tensioning device of external wheel, relate to truss and handrail, this handrail strap tensioning device of external wheel comprises the handrail carriage that is connected on the truss, be installed with at least one screw rod on the described handrail carriage, be connected with nut on this screw rod, described handrail compressing member is socketed on the screw rod, and be connected with holddown spring between nut and the handrail compressing member, the contact roller that is provided with on the described handrail compressing member presses the handrail placement in addition, when then using,, can adjust the longitudinal travel of handrail compressing member by swivel nut, thereby guarantee handrail tensioner all the time, can 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 handrail strap tensioning device of external wheel.
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 swelling device, but, the general out of reach requirement of the swelling device that prior art adopted, thus cause the operation of handrail not steady, even can't move.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of handrail strap tensioning device of external wheel, thereby guarantee handrail in tension all the time, promptly handrail can move reposefully.
For realizing above technical purpose, the present invention will adopt following technical scheme:
A kind of handrail strap tensioning device of external wheel, relate to truss and handrail, this handrail strap tensioning device of external wheel comprises the handrail carriage that is connected on the truss, be installed with at least one screw rod on the described handrail carriage, be connected with nut on this screw rod, described handrail compressing member is socketed on the screw rod, and is connected with holddown spring between nut and the handrail compressing member, and the contact roller that is provided with on the described handrail compressing member presses the handrail placement in addition.
Described screw rod is two.
According to above technical scheme, can realize following beneficial effect:
1. owing to the invention provides a kind of handrail strap tensioning device of external wheel, when then using,, can adjust the longitudinal travel of handrail compressing member, thereby guarantee handrail tensioner all the time, can guarantee the smooth running of handrail effectively by swivel nut;
2. screw rod of the present invention is two, guarantees that then the support of handrail compressing member is more steady, and rotatablely moving of nut adjusted the longitudinal travel of handrail compressing member more exactly simultaneously.
