Further, be provided with circular arc chamfering between described arc cap and described round bar body, described circular arc chamfering is between the lower surface and the upper surface of described round bar body of described arc cap.
Further, scrobicular ring is provided with between the internal face of the round bar body that described partition seam is right.
Further, the conical surface tapering be located at described between the lower surface of round bar body one end and the outer surface of described round bar body is 60 degree.
Further, the outer surface of described round bar body, arc cap and described pin is equipped with zinc coat.
Further, described arc cap and described round bar body are integrated and make.
The beneficial effect that the utility model brings is:
In the utility model, described driving into type expansion gecko realizes fastening effect by the method that driving into type expands, can arbitrarily remove when no time, also wall surface levelling advantage can be kept remarkable, and circular arc chamfering can increase fastening effect, simultaneously on the outer surface of round bar body, arc cap and described pin, be equipped with zinc coat, corrosion-resistant effect can be played in long-time using process, and easy to operate, safety and stability, practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of driving into type expansion gecko described in the utility model.
Fig. 2 is the structural representation of round bar body described in the utility model.
Fig. 3 is the complete section schematic diagram of driving into type expansion gecko described in the utility model.
The label that in figure, component names is corresponding is as follows:
1, round bar body; 2, pin; 3, conical surface; 4, the first dovetail groove; 5, the second dovetail groove; 6, " work " font bottom surface; 7, arc cap; 8, circular groove; 9, axial receiving bore; 10, partition seam; 11, circular arc chamfering; 12, scrobicular ring.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As the embodiment of driving into type expansion gecko described in the utility model, as Fig. 1, shown in Fig. 2 and Fig. 3, comprise round bar body 1 and pin 2, conical surface 3 is provided with between the lower surface of described round bar body 1 one end and the outer surface of described round bar body 1, the tapering of described conical surface 3 is 50 ~ 70 degree, the outer wall of described round bar body 1 is respectively equipped with the first dovetail groove 4 and the second dovetail groove 5, the lower surface of described round bar body 1 and the bottom surface 6 be provided with between described first dovetail groove 4 and described second dovetail groove 5 in " work " font, the other end of described round bar body 1 is provided with arc cap 7, described arc cap 7 is provided with circular groove 8, described round bar body 1 be axially provided with axial receiving bore 9, and one end of described axial receiving bore 9 is connected with described circular groove 8, the other end of described axial receiving bore 9 is each passed through described first dovetail groove 4 and described second dovetail groove 5 and forms partition seam 10, described pin 2 is each passed through described circular groove 8 and described axial receiving bore 9, and between described partition seam 10 and described axial receiving bore 9.Now pin 2 is squeezed in axial receiving bore 9, and extend between partition seam 10 and described axial receiving bore 9 by the upper surface of round bar body 1 along axis direction, round bar body 1 is divided into the uniform expanding block (not shown) of polylith by partition seam 10, by external force, pin 2 is in axial direction squeezed into the tail end of round bar body 1, and strut scrobicular ring 12 to form the stressed expansion of expanding block and come, make body of wall, expanding block and scrobicular ring 12 form friction self-locking, then fastening effect is realized by connecting pre-drilled hole wall (not shown), and then serve the effect be connected and fixed, and this kind of Placement relatively firm stable.Arbitrarily can remove when no time, wall surface levelling advantage can be kept remarkable, the occasions such as the various finishing of extensive use and furred ceiling simultaneously.
