In order to achieve the above object, stair column transverse tube connector of the present utility model, comprise the transverse tube corner pieces and the stud location part that are box section, be provided with between described two box sections described two box section central axis are rotated in same plane and can position rotating the syndeton of angle, described syndeton comprises that the middle part is provided with reeded spill axis of rotation, is arranged on the locking member that convex axis of rotation, the described convex axis of rotation in location and spill axis of rotation in the described groove relatively rotates angle.
Particularly, described locking member comprises the bearing pin of central axis perpendicular to the Plane of rotation of described two box section central axis; Described convex axis of rotation is arranged on an end of one of them box section; The end that described spill axis of rotation is relative with slot opening is arranged on the side of another box section; Centre bore is all established in convex axis of rotation and groove two side, and described bearing pin is arranged in the described centre bore.
Further, described convex axis of rotation is provided with the concave arc shape breach, and the bottom portion of groove of described spill axis of rotation is provided with and the suitable protuberance of described concave arc shape breach.
Wherein, be equipped with the installing hole that is used to connect intubate on the described box section sidewall.Be provided with convex tendon around the described box section outer openings end.
Above-mentioned structure, during the stair railing assembling, insert transverse tube and column in the box section respectively, can be more fastening be connected column and transverse tube easily, can reach simultaneously the angle between any adjustment column and the transverse tube, make its installation more flexible, convenient, outward appearance is more elegant in appearance, can better prevent that tubing from getting rusty.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
First specific embodiment of stair column transverse tube connector of the present utility model shown in Fig. 1-10, comprises box section 1, box section 2, and box section 1 sidewall is provided with the installing hole that is used to connect transverse tube, and box section 2 sidewalls are provided with the installing hole that is used to connect column; Be provided with annular convex rib 11 around the box section 1 outer openings end, box section 2 sidewalls are provided with " worker " font convex tendon 21 of strengthening intensity; Convex axis of rotation 12 is established in box section 1 end, establishes arcs of recesses breach 13 on the axis of rotation 12; Box section 2 sidewalls are established spill axis of rotation 22, groove is established at spill axis of rotation 22 middle parts, the bottom portion of groove inwall is upwards established protuberance, convex axis of rotation 12 places in the groove, the protuberance correspondence places arcs of recesses breach 23, the spill axis of rotation 22 of convex axis of rotation 12 and both sides thereof is provided with the centre bore of centerline direction unanimity, and the central axial direction of centre bore is vertical respectively at the central axial direction of box section 1 and box section 2; Bolt is imported in the centre bore, and the convex axis of rotation rotates the box section 1 of adjusting sheathed transverse tube and the angle between the sheathed column box section 2 to predetermined angular relative to the spill axis of rotation, and convex axis of rotation and spill axis of rotation are locked in the set bolt end.
Above-mentioned structure, at first the square column with stair inserts in the box section 2 (square column central axis is consistent with box section 2 central axial direction), sets size positions and be as the criterion on drawing, itself and column is locked in installing hole with self-tapping screw; Then the stair transverse tube is inserted in the box section 1 (square transverse tube central axis is consistent with box section 1 central axial direction), in installing hole, itself and transverse tube are locked with self-tapping screw; Again spill axis of rotation, convex axis of rotation are combined together at last by bolt or rivet (central axis of bolt or rivet is consistent with the centerline direction in convex axis of rotation and spill rotating shaft center hole) and penetrate the state that reaches coaxial in the centre bore, because the axis direction of bolt or rivet is all vertical with transverse tube and column central axial direction, like this, transverse tube and column can rotate in same plane, after adjusting to the angle consistent with the scene, two independent accessory are locked mutually with locking member at its shaft core position, thereby make it reach an integrality, i.e. assembling is finished; Improved the setting angle flexibility between column and the transverse tube greatly, guaranteed that effectively tubing revises the problem of rustiness of the fracture that causes through the scene, make tubing within it portion obtained the effect of sealing, convex tendon 11 edges of box section 1 inlet have exceeded normal wall thickness, reinforcing rib 21 on box section 2 sidewalls makes the intensity of the column transverse tube connector that aluminum alloy material is made itself significantly exceed several times of other interior type Connection Card, strong assurance the bulk strength of stair railing, the external physical characteristic of simplicity generosity makes that the stair railing assembling is more succinctly transparent, makes the whole structure of its stair railing smooth more attractive in appearance.Make the stair railing assembling more convenient simple, prevented the problem of rustiness of tubing fracture fully, improve the application life of packaging efficiency and stair railing greatly, made its stair railing integral surface outward appearance more attractive in appearance, also improved the intensity of stair railing assembling simultaneously greatly.Be mainly used in indoor, outdoor various stair railing assemblings fixed network, various gauge size square tubes, quarter bend all have the coupling accessory.
As second specific embodiment of the present utility model, shown in Fig. 2-6,11-15, the direction pipe that is used to connect column is wedge shape 3, and this kind structure is used for the column better effects if that both sides all connect transverse tube.
Easier for installation quick, intensity is more firm, and syndeton and box section adopt aluminum alloy material, makes the weight saving of railing integral body, the railing outward appearance has also been played beautified effect; It is mainly used in outdoor various guardrail or fence assembling fixed network.Connection column and transverse tube that can be more fastening, make its outward appearance more elegant in appearance, can better prevent that tubing from getting rusty, make the guardrail assembling more convenient simple, prevented the problem of rustiness of tubing fracture fully, improve the application life of packaging efficiency and railing greatly, made its fence integral surface outward appearance more attractive in appearance, also improved the intensity of fence assembling simultaneously greatly.Be mainly used in indoor, outdoor various guardrails or fence assembling fixed network, various gauge size quarter bends all have supporting.
The utility model is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, every to utilize above-mentioned stair column transverse tube connector all be a kind of distortion of the present utility model, all should think and drop within the utility model protection domain.
