Abstract
The utility model relates to a turning joint for a staircase handrail, which consists of a switching sphere and two sleeves. The switching sphere is positioned between the two sleeves and formed by splicing two hemispheres; a notch is formed at the inner end of each sleeve along the axis of the switching sphere; through holes are formed on the surfaces of the two hemispheres; a bolt penetrates through the through holes and is connected with a bolt cap; and the two hemispheres rotate through pin shafts penetrating through the inside of the two hemispheres. The turning joint has a reasonable designed structure, realizes the arbitrary adjustment of switching angles, has wide application range, is not required to be measured and processed in advance during the assembly and can be adjusted only through loosening the blot according to practical situations, so that the assembly and adjustment are convenient, the installation procedure is greatly simplified, and the installation efficiency is improved. In addition, because the two hemispheres and the sleeves are processed into integrated structures, the firm performance is greatly improved, and the potential safety hazards formed after the installation of a conventional turning part and the handrail sleeves are eliminated.
Description
Technical field
The utility model relates to a kind of joint, especially a kind of balustrade turning joint.
Background technology
Hand rail is located to be provided with in the stair of buildings in general (hospital, nursing home or public place building), aisle etc., walks with the secondary row people.Normally used is the metal tube handrail, and when this handrail was provided with, its round metal tubulose grab bar need just need a turning structure this moment along metope or physical features turning splicing usually.The turning structure of traditional handrails thick stick is: do 〉=45 otch at the end face that two tubular type handrails draw, weld or riveted and fixed the butt joint back then, forms 〉=90 wedge angle in the corner.This kind docking mode structure not only troublesome poeration, work efficiency is low, and the handrail that has welded is wedge angle, and is both dangerous outside easily damaging during use, inconvenient again, moulding is not attractive in appearance yet.Occurred a kind ofly connecting the docking structure of two tubular type grab bars with the shaping elbow at above-mentioned shortcoming market, though this structure improves to some extent from safety and aesthetic property, it is at the construction fit on, still exist waste time and energy, defective that work efficiency is low.In addition, be split-type structural in existing docking structure because between turning part and the handrail socketed pipe, need connect by fixture during installation, therefore in use also exist potential safety hazard.
The utility model content
At the weak point that exists in the above-mentioned technology, the utility model provides a kind of angle of turn of joint freely to adjust, and has eliminated a kind of balustrade turning joint that has potential safety hazard after existing turning part and handrail socketed pipe are installed.
For achieving the above object, the utility model provides a kind of balustrade turning joint, constitute by a switching spheroid and two socketed pipes, described switching spheroid is between described two socketed pipes, described switching spheroid is formed by two hemisphere amalgamations,, an end of described hemisphere and described socketed pipe is that two described hemispheres of integral structure rotate by running through its inner bearing pin.
Described socketed pipe the inner is provided with a kerf along the axis of described switching spheroid.
One end of described socketed pipe also is provided with the depression sphere, and the surface of described depression sphere and described switching spheroid is slidingly matched.
Described bearing pin is a bolt, is provided with through hole on two described hemispheroidal surfaces, and described bolt-through is connected with nut in described through hole.
Compared with prior art, the utlity model has following advantage:
The utility model provides a kind of balustrade turning joint, constitute by a switching spheroid and two socketed pipes, the switching spheroid is between two socketed pipes, the switching spheroid is formed by two hemisphere amalgamations, hemisphere and socketed pipe are integral structure, are provided with a kerf at the inner axis along the switching spheroid of socketed pipe, are provided with through hole on two hemispheroidal surfaces, bolt-through is connected with nut in through hole, and two hemispheres rotate by running through its inner bearing pin.The utility model project organization is reasonable, realized the adjustable arbitrarily of switching angle, applied widely, during assembling, need not to carry out prior measurement and processing, can be by the actual conditions adjustment, also elasticity bolt during adjustment, very convenient, compared with prior art, simplify installation procedure greatly, improved installation effectiveness.In addition, owing to, increased substantially firm performance, eliminated existing turning part and handrail socketed pipe the potential safety hazard of existence afterwards has been installed hemisphere and the socketed pipe formula structure that is processed as one.

7 nuts
The specific embodiment
For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the utility model provides a kind of balustrade turning joint, constitute by a switching spheroid and two socketed pipes 1, the outer end of socketed pipe 1 is connected with balustrade, the switching spheroid is between two socketed pipes 1, the switching spheroid is formed by two hemisphere 2 amalgamations, is provided with vertical amalgamation face 3 at the opposite face of two hemispheres 2.Hemisphere 2 is an integral structure with the inner of socketed pipe 1, is provided with through hole (not describing among the figure) two hemispheroidal inside, and bolt-through is connected with the nut 7 that is arranged on hemisphere 2 one sides in this through hole.This bearing pin is that 6, two hemispheres 2 of bolt rotate by running through its inner bolt 6.Socketed pipe 1 inner axis along the switching spheroid is provided with a kerf 4.Also be provided with depression sphere 5 in the inner of socketed pipe 1, this depression sphere 5 is slidingly matched with the surface of switching spheroid.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
Claims (4)
1. balustrade turning joint, it is characterized in that, constitute by a switching spheroid and two socketed pipes, described switching spheroid is between described two socketed pipes, described switching spheroid is formed by two hemisphere amalgamations, one end of described hemisphere and described socketed pipe is an integral structure, and two described hemispheres rotate by running through its inner bearing pin.
