Two second connecting ends of the two connecting members are mutually hinged through a group of fastening assemblies and are respectively provided with a protruding connecting part. The fastening assemblies are arranged in the connecting parts of the two connecting members in a penetrating mode. The handrail face tube corner accessory of the stair railing has the advantages of being simple and compact in structure, convenient to install and strong in connecting tightness.
Description
Technical field
The utility model relates to the stair railing structure, relates in particular to stair railing handrail facial canal corner fitting.
Background technology
Stair railing all is provided with the bent sub that connects the handrail facial canal in the corner, because the angle difference between the halfpace stair guardrail of different stair, the bent sub of handrail facial canal needs certain versatility can save cost of production.Considering structure, under the situation of composite factors such as cost and property easy for installation, existing stair railing handrail facial canal corner fitting adopts two connectors that are the cooperation of " concavo-convex " shape to make usually, promptly on a connector, be provided with the groove that forms by two sidewalls, establish on another connector one with the lug boss of groove fit, during connection, lug boss is inserted in the groove and a securing member is passed in two side and this lug boss simultaneously and realizes being connected, pine by regulating securing member and tightly can make two side clamping or release projection portion, and then make two connectors relatively rotate or be connected and fixed, after adjusting angle, need tighten securing member makes the good tightness of maintenance between two connectors rotate each other preventing, yet, because connector generally adopts rigid material to make, non-deformability is strong, and the adjusting of securing member is required great effort very much when fastening, even can not make the two side effectively clamp lug boss, two connectors relatively rotate easily, and it is poor to connect tightness.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple and compact for structure, easy for installation, strong stair railing handrail facial canal corner fitting of connection tightness is provided.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of stair railing handrail facial canal corner fitting, comprise two connectors, each connector comprises that one is used for first link that is connected with described handrail facial canal and one and is used for interconnective second link, second link of described two connectors is hinged by one group of fastening assembly, it is characterized in that: second link of each connector is equipped with the connecting portion of a protrusion, and described fastening assembly is arranged in the connecting portion of described two connectors.
As further improvement of the utility model:
Offer the groove that cooperates with the connecting portion of another connector on each connector, cooperate for surface of revolution between described groove and the corresponding connecting portion.
Described fastening assembly comprises fastening bolt and clamp nut, offers the bolt counter sink that cooperates with the head of fastening bolt on the connecting portion of a connector, offers on the connecting portion of another part connector and clamp nut nut engaged locating hole.
Compared with prior art, advantage of the present utility model is: stair railing handrail facial canal corner fitting of the present utility model, two connectors interconnect by the connecting portion of projection, avoided when connector adopts rigid material to make, connecting the shortcoming of tightness difference, two connecting portions are closely cooperated and produce enough spline power by fastening assembly fastening, effectively guarantee the connection tightness between two connectors; Offer the groove that cooperates with the connecting portion of another connector on each connector, for surface of revolution cooperates, occur when avoiding two connectors to carry out angle adjustment interfering between groove and the corresponding connecting portion, and make the structure of whole accessory simple more compact; Fastening assembly adopts fastening bolt and clamp nut, offer the bolt counter sink in two connectors on one the connecting portion, offer the nut locating hole on the connecting portion of another part, during installation, the nut locating hole carries out spline to clamp nut, and fastening bolt can directly cooperate with it to be tightened, quick and easy for installation, the bolt head of the fastening bolt after the installation places the bolt counter sink, and clamp nut places the nut locating hole, has kept the overall aesthetics of accessory.
