Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of connector installed for stair railing cross bar, this connector is adopted to be applicable to the installation of differing tilt angles stair railing cross bar, without the need to the connector at prefabricated multiple angle of inclination, reduce cost of production, stair railing cross bar simple installation, improves installation effectiveness.
For solving the problems of the technologies described above, the connector that the utility model is used for the installation of stair railing cross bar comprises Plug Division, connecting portion and fastening bolt, described Plug Division comprises cylindrical shell and two otic placodes of bottom end opening, described two otic placodes have through hole and described cylindrical shell end face is located at interval, described connecting portion comprises supporting plate and swivel plate, described swivel plate is vertical at described supporting plate bottom surface, described swivel plate has through hole and inserts between two otic placodes of described Plug Division, described fastening bolt penetrates the through hole of described two otic placodes and swivel plate and passes through fastening nuts, described two ends of bearing plate is respectively equipped with cross bar fixing hole.
Further, the cylindrical shell end face of described Plug Division is connected by level and smooth cambered surface with between two otic placodes.
Further, the cylindrical shell end face between two otic placodes of described Plug Division is indent arcwall face, and the swivel plate end face of described connecting portion is the evagination arcwall face mated with described indent arcwall face.
Further, two otic placode lateral surfaces of described Plug Division are respectively equipped with circular counter bore and hexagonal counterbore and coaxial with the through hole of two otic placodes.
Further, the supporting plate top surface of described connecting portion is arcwall face.
The connector being used for the installation of stair railing cross bar due to the utility model have employed technique scheme, namely this connector comprises Plug Division, connecting portion and fastening bolt, described Plug Division comprises cylindrical shell and two otic placodes of bottom end opening, described two otic placodes have through hole and described cylindrical shell end face is located at interval, described connecting portion comprises supporting plate and swivel plate, described swivel plate is vertical at described supporting plate bottom surface, described swivel plate has through hole and inserts between two otic placodes of described Plug Division, described fastening bolt penetrates the through hole of described two otic placodes and swivel plate and passes through fastening nuts, described two ends of bearing plate is respectively equipped with cross bar fixing hole.This connector is applicable to the installation of differing tilt angles stair railing cross bar, and without the need to the connector at prefabricated multiple angle of inclination, reduce cost of production, stair railing cross bar simple installation, improves installation effectiveness.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the connector schematic diagram that the utility model is installed for stair railing cross bar;
Fig. 2 is the structural representation of this connector Plug Division;
Fig. 3 is the lateral view of Fig. 2;
Fig. 4 is the structural representation of this connector connecting portion.
Detailed description of the invention
Embodiment as shown in Figures 1 to 4, the connector that the utility model is used for the installation of stair railing cross bar comprises Plug Division 2, connecting portion 1 and fastening bolt 3, described Plug Division 2 comprises cylindrical shell 21 and two otic placodes 22 of bottom end opening, described two otic placodes 22 have through hole 23 and described cylindrical shell 21 end face is located at interval, described connecting portion 1 comprises supporting plate 11 and swivel plate 12, described swivel plate 12 is vertical at described supporting plate 11 bottom surface, described swivel plate 12 has through hole 13 and inserts between two otic placodes 22 of described Plug Division 2, described fastening bolt 3 penetrates the through hole 23 of described two otic placodes 22 and swivel plate 12, 13 and by nut 4 fastening, described supporting plate 11 two ends are respectively equipped with cross bar fixing hole 14.
When stair railing is installed, column is located at stair side by base interval, when installing cross bar, the cylindrical shell of this connector is inserted in column end face, cross bar is set up in supporting plate top surface and twists in cross bar bottom surface by the cross bar fixing hole that screw penetrates two ends of bearing plate, cross bar and supporting plate are fixed, the swivel plate of rotation between two otic placodes is to adjust the angle of inclination of cross bar, until cross bar be adjusted to move towards with stair consistent after, tighten fastening bolt by the Plug Division of this connector and connecting portion fastening, the installation of cross bar can be completed.
Preferably, cylindrical shell 21 end face of described Plug Division 2 is connected by level and smooth cambered surface 24 with between two otic placodes 22.Level and smooth cambered surface connects the aesthetic property that improve this connector, increases the anglec of rotation of connecting portion simultaneously, and the cross bar being applicable to high inclination-angle is installed.
Preferably, cylindrical shell 21 end face between two otic placodes 22 of described Plug Division 2 is indent arcwall face 25, and swivel plate 12 end face of described connecting portion 1 is the evagination arcwall face 15 mated with described indent arcwall face 25.Indent arcwall face mates with evagination arcwall face, makes the rotation of swivel plate in two otic placodes more flexible, improves the anglec of rotation of swivel plate.
Preferably, two otic placode 22 lateral surfaces of described Plug Division 2 are respectively equipped with circular counter bore 26 and hexagonal counterbore 27 and coaxial with the through hole 23 of two otic placodes 22.Circular counter bore and hexagonal counterbore make the installation exercise of stair railing more convenient, after fastening bolt penetrates, head end is positioned at circular counter bore, and nut is positioned at hexagonal counterbore, now only need to use screwdriver to screw fastening bolt and can fix Plug Division and connecting portion, improve installation effectiveness.
Preferably, supporting plate 11 end face of described connecting portion 1 is arcwall face 16.Can there be various shape in the cross bar cross section of stair railing, is mostly circular or closely oval, and when therefore cross bar is positioned at supporting plate top surface, the arcwall face of supporting plate top surface can be fitted cross bar bottom surface, plays effective supporting role to cross bar.
This connector is connected column and the cross bar of stair railing respectively by Plug Division and connecting portion, and the installation requirement of differing tilt angles cross bar is met by the angle of adjustment connecting portion in Plug Division, thus without the need to the connector at prefabricated multiple angle of inclination, save cost, improve installation effectiveness.
