Abstract
The utility model discloses a fastener for a construction steel pipe, which comprises an inner fastener seat and an outer fastener cover which are hinged together through a hinged shaft, wherein locking levels are arranged at the open ends of the inner fastener seat and the outer fastener cover; reinforcing ribs are arranged on the outer surface of the outer fastener cover; and a wear layer is arranged between the reinforcing ribs and the outer surface of the outer fastener cover. The outer fastener cover is high in intensity, less susceptible to damage, wear-resistant, and corrosion-resistant, and has a long service life. Therefore, the fastener has a wide market application range and remarkable economical and social benefits.
Description
Technical field:
The utility model relates to the building fittings field, particularly relates to a kind of building steel tube fastener.
Background technology:
Existing building steel tube fastener has ten sub-right-angle couplers, corner fastener, to clasp.One these fasteners all are through jointed shaft that interior Button Block, outer buckle closure is hinged, are provided with check lock lever at the openend of inside and outside buckle closure.But its outer buckle closure of existing building steel tube fastener is consistent from the wall thickness of hinged axle head to openend along its connecting pipe length direction, and its intensity is low, is prone in the use fragmentation takes place, and causes production accident.
For example application number is 200720029238.2; Publication number is 201129030 Chinese patent " building steel tube fastener "; Disclose and the utility model discloses a kind of building steel tube fastener; Comprise that through the hinged interior Button Block of jointed shaft, outer buckle closure interior Button Block is provided with check lock lever with the openend of outer buckle closure, outside described, is provided with convex tendon on the external surface of buckle closure.But the cover plate of this utility model is in long-term the use, and reinforcing rib and outer buckle closure easy abrasion distortion cause accident to take place.
The utility model content:
The purpose of the utility model is to overcome the problems referred to above of building steel tube fastener in the prior art, proposes a kind of building steel tube fastener.Adopt the outer buckle closure intensity of the utility model high, be difficult for broken, wear resistant corrosion resistant, and long service life, application market is wide, and remarkable economical and social benefit are arranged.
The utility model adopts following technical scheme to realize:
A kind of building steel tube fastener; Comprise through the hinged interior Button Block of jointed shaft, outer buckle closure; Interior Button Block is provided with check lock lever with the openend of outer buckle closure, and the external surface of said outer buckle closure is provided with reinforcing rib, it is characterized in that: be provided with wearing layer between the external surface of said reinforcing rib and outer buckle closure.
Described reinforcing rib is positioned at the two opposite edges portions of outer buckle closure external surface from hinged axle head to openend.
Described reinforcing rib is positioned at the position at the axial two ends of outer buckle closure external surface, and roughly is the twoport font.
The utility model compared with prior art, its advantage is:
The utility model is employed between the external surface of reinforcing rib and outer buckle closure and is provided with wearing layer, and wearing layer is the PVC layer, make outer buckle closure not only intensity high, be difficult for broken, and wear resistant corrosion resistant, long service life, application market is wide, and remarkable economical and social benefit are arranged.
