Utility model content
The technical problems to be solved in the utility model is to provide a kind of metal rod connector for building, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of metal rod connector for building, in order to be fixed in the docking site of two metal rods, comprise: the circular body of a metal material, it comprises an axial through manhole and the tube wall being positioned at through hole periphery, described manhole internal diameter passes wherein for corresponding metal rod, the internal face of described tube wall has concavo-convex rough contact surface, and described circular body tube wall internal face only forms screw thread in the contact site contacted with metal rod and forms described rough contact surface; And the fixture of multiple metal material, interval is fixedly arranged in the tube wall of circular body, and stretches in the through hole of circular body, in order to be fixed in circular body by metal rod.
Described rough contact surface forms the screw thread of two sections of different hands of spiral, and the section configuration of described two sections of screw threads is the triangle with two inclined-planes, and described two junctions, inclined-plane form barb, and the barb of described two sections of screw threads is reverse each other.
The tube wall of described circular body arranges multiple linearly spaced apart vertically and be communicated with the coupling hole of through hole, and described coupling hole is screw, and with contact site diametrically, described fixture is bolted in respectively in the coupling hole of circular body and is fixed by metal rod.
Described fixture is self-tapping screw, and described self-tapping screw has drilling blade, and described self-tapping screw is bolted in the fixing hole of circular body respectively, is pierced in metal rod fixed by drilling blade.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, metal rod connector for building of the present utility model, be fixed in the docking site place of two metal rods, rough contact surface is formed by the internal face of circular body, metal rod is fixed by the fixture be fixedly arranged on circular body, make the position that rough contact surface contacts as metal rod, increase the frictional resistance between metal rod and circular body, promote linking steady character to each other, and utilize the through hole inside in circular body need not other components additional, through hole internal diameter is made to wear wherein for metal rod, and make circular body under the condition of the wall thickness of preliminary dimension, reduced round tube body diameter, reduce material, reduce costs, and the rigidity of circular body itself can be improved, when making metal rod connector be fixed in the docking site of two metal rods, not easily damage because of External Force Acting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the rough contact surface of the utility model embodiment.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the utility model embodiment provides a kind of metal rod connector for building, it is in order to be fixed in the docking site of two metal rods, described metal rod 30 connector comprises circular body 10 and a multiple fixture 20, described circular body 10 is made by metal material, described circular body 10 comprises an axial through manhole 11 and is positioned at the tube wall 12 of through hole 11 periphery, described manhole 11 internal diameter may correspond in metal rod 30 external diameter, metal rod 30 be able to be worn wherein, and only stay small―gap suture between tube wall 12 internal face of described two metal rods 30 and circular body 10, tube wall 12 internal face of described circular body 10 forms concavo-convex rough contact surface 13, described circular body 10 tube wall 12 internal face only forms screw thread in the contact site contacted with metal rod 30 and forms described rough contact surface 13, namely described tapped eccentric forms in the manhole 11 of circular body 10 in eccentric state, and form described rough contact surface 13 in the tube wall 12 local interior wall face of circular body 10.
As shown in Figure 2, when the tube wall of described circular body 10 forms screw-shaped rough contact surface 13, rough contact surface 13 forms the screw thread of two sections of different hands of spiral, the section configuration of described two sections of screw threads is the triangle with two inclined-planes 131,132, described two junctions, inclined-plane 131,132 form barb 133, wherein be reversed good each other with the barb 133 of described two sections of screw threads, promoted the frictional resistance of rough contact surface 13 by barb 133.
In described circular body 10, its tube wall 12 arranges multiple linearly spaced apart vertically and be communicated with the coupling hole 14 of through hole 11, and described coupling hole 14 is screw, and with contact site diametrically, in order to provide fixture 20 to set firmly wherein, and can stretch in through hole 11.
Described multiple fixture 20 is made by metal material, and be greater than the metal material of circular body 10 and metal rod 30 for hardness, fixture 20 interval is bolted in the screw of circular body 10 tube wall 12, and can stretch in the through hole 11 of circular body 10, parameters such as the distance that the length of the circular body 10 of the quantity basis of described fixture 20, fixture 20 distribute and determining.
