Abstract

The utility model discloses a stair combination connecting piece and aims to solve the problems of unadjustable installation angle and the like in the prior art. The stair combination connecting piece consists of a fixed piece with a rectangle cross section and a movable connecting piece, wherein a groove is arranged downwards between two opposite side walls at one end of the fixed piece along the length direction; the upper edges of the two side walls are of a symmetrical convex arc shape; the middle parts of the two side walls are provided with center holes; one end of the movable connecting piece is provided with a rectangular tube; the middle part of the other end of the movable connecting piece is outwards provided with a circular roller of which the thickness is less than the width of the rectangular tube; and the circular roller is arranged in the groove and is arranged in the center holes by pins to be connected with the fixed piece. The circular roller is connected with the fixed piece, the angle is freely adjusted to be matched with the actual angle of the civil work construction, and when the angle is adjusted to a suitable angle, the movable connecting piece and the fixed piece are locked by an anti-theft screw so as to guarantee the angle unchanged and also achieve stable strength and overall coordination. The rectangular tube is connected with a transverse rectangular tube and the edge of the end port of the transverse rectangular tube is completely sealed and contained in the groove of the rectangular tube so as to guarantee that the tubes adopt original materials, beautify the port edge and make the whole of stair guardrail smoother and firmer.

Description

The stair combined connection component

Technical field

The utility model relates to the stair combined connection component that a kind of stair railing assembling fixture, especially angle can be adjusted.

Background technology

General employing railing keeper is fixedlyed connected between the upright quarter bend of existing stair railing and the horizontal quarter bend, the angle of railing keeper can not be adjusted, interface is handled attractive in appearance inadequately, installation dimension to railing in work progress is had relatively high expectations, and inconvenient assembly and disassembly just are difficult for doing finishing again in case install, and difficulty is bigger during operation, the man power and material of the cost of dress stair railing is more, causes cost higher.

The utility model content

In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of stair combined connection component flexible for installation, easy to use.

In order to achieve the above object, stair combined connection component of the present utility model, constitute by fixture and active connection, wherein, described fixture cross section is a rectangle, wherein be directed downwards along described fastener length between the end two lateral walls and be provided with groove, described groove two side top edge is symmetrical convex arc shaped, and middle part, described groove two side is provided with the corresponding consistent centre bore in center; Described active connection one end is a rectangular tube, and to being outside equipped with the round roller of thickness less than described rectangular tube thickness, described round roller places to be arranged in the described centre bore in the described groove and by bearing pin and is connected with described fixture relatively at other end middle part.

Wherein, the convex arc radius of described round roller radius and described groove two side top edge is suitable.

Particularly, it is suitable with described groove two side top edge respectively that the rectangle pipe end of described active connection is positioned at the inner edge of described round roller both sides.

Above-mentioned structure, the main effect of round roller part of active connection is to be responsible for being connected with fixture,

This round roller is free to adjust the actual angle of angle with the coordinative construction civil engineering, after adjusting to suitable angle, just active connection and fixture are locked, guarantee that its isogonal while has also reached strength of stability and whole harmony with the stainless steel anti-theft screw; The main horizontal quarter bend of connection of being responsible for of the rectangular tube part of active connection, the whole rectangular tube groove of this part can horizontal quarter bend port edge seal fully be included in the inside, guaranteed the original material of tubing, also beautified simultaneously egress edge, make that the whole stair railing of striding is more smooth firm, elegant in appearance.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in 1-19, stair combined connection component 001 of the present utility model, constitute by fixture 1 and active connection 2, wherein, described fixture cross section is a rectangle, wherein be directed downwards along described fastener length between the end two lateral walls 11 and be provided with groove 12, described groove two side top edge is symmetrical convex arc shaped, middle part, described groove two side is provided with the corresponding consistent centre bore 13 in center, described centre bore is used for installing rotating shaft, the described fixture other end is a bottom face, described bottom face and described groove corresponding position are provided with rectangle pit 14, it is porose 15 that described rectangle pit middle part is provided with, and other bottom face corresponding described groove two side is respectively divided in described rectangle pit both sides, the both sides bottom face along described rectangle pit length direction respectively symmetry upwards be arranged at intervals with three rectangle jacks 16; Described active connection one end is a rectangular tube 21, other end middle part is relatively to being outside equipped with the round roller 22 of thickness less than described rectangular tube thickness, and described round roller places in the described groove and is arranged in by bearing pin in the centre bore 13 of its centre bore 23 and described fixture and is connected with described fixture.

It is suitable with described groove two side top edge respectively that the rectangle pipe end of described active connection is positioned at the inner edge of described round roller both sides.

Above-mentioned structure, the round roller of active connection is placed in the groove of described fixture, described fixture is connected with active connection along its centre bore by bearing pin, because the rectangular tube male part inner edge of described groove two side top edge and described round roller both sides cooperatively interacts, described round roller can rotate along described bearing pin in the space of described groove flexibly, round roller is free to adjust the actual angle of angle with the coordinative construction civil engineering, after adjusting to suitable angle, just active connection and fixture are locked, guarantee that its isogonal while has also reached strength of stability and whole harmony with stainless steel anti-theft screw 03; The rectangular tube part phase society seal groove 01 main horizontal quarter bend 02 of connection of being responsible for of active connection, the whole rectangular tube groove of this part can horizontal quarter bend port edge seal fully be included in the inside, guaranteed the original material of tubing, also beautified simultaneously egress edge, make that the whole stair railing of striding is more smooth firm, elegant in appearance.The corresponding end of described fixture and described groove is used to install and fix stud end, can plug be installed according to concrete column and be provided with.
