Embodiment
Below with reference to accompanying drawings exemplary embodiment disclosed in the utility model is described in more detail.Although show exemplary embodiment disclosed in the utility model in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment that sets forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
As shown in Fig. 1 ~ Fig. 6, in an embodiment of the present utility model, provide a kind of for plastic screw post 1 with the use of screw pole top strengthen structure, it is cylindrical sleeves structure that structure is strengthened at described screw pole top, the top that structure is sleeved on described plastic screw post 1 is strengthened at described screw pole top, the barrel that structure is strengthened at described screw pole top is provided with the scarfing unit increasing described screw pole top reinforcement structure and described plastic screw post combination force, and described scarfing unit interlocking is on the gusset of described plastic screw post 1.
It is cylindrical sleeves structure that structure is strengthened at screw pole top in the present embodiment, screw pole top is strengthened structure and is sleeved on after on plastic screw post 1, the scarfing unit that screw pole top is strengthened on the outer side tube-wall of structure is rabbeted on the gusset of plastic screw post 1, make screw pole top strengthen structure and be more firmly sleeved on difficult drop-off on plastic screw post 1, facilitate follow-up screw of beating and operate; In addition, after screw fastening, screw pole top reinforcement structure is pressed between plastic screw post 1 and opponent's part 8, enhances fastening effect.
As shown in FIG. 1 to 3, in another embodiment of the present utility model, it is screw pole strengthening cap 2 that structure is strengthened at described screw pole top, scarfing unit on described screw pole strengthening cap 2 is multiple concave inward structures 3, preferably, in this embodiment, concave inward structure 3 is hemispherical concave inward structure or cone-shaped concave inward structure (not shown), described multiple concave inward structure 3 is evenly distributed on the outer side tube-wall of described screw pole strengthening cap 2, and described concave inward structure 3 is rabbeted on the gusset of described plastic screw post 1.
In the present embodiment, the outer side tube-wall upper punch of screw pole strengthening cap 2 goes out multiple concave inward structure 3, because the hardness of plastic screw post 1 is lower, therefore when screw pole strengthening cap 2 coordinates with plastic screw post 1, while firmly pressing screw pole strengthening cap 2 downwards, concave inward structure 3 interferes with the gusset of plastic screw post and rabbets on the gusset of plastic screw post 1, screw pole strengthening cap 2 is made to be sleeved on difficult drop-off after on plastic screw post 1, strengthen fastening, locking effect, facilitate follow-up screw of beating and operate; In addition, after screw fastening, screw pole strengthening cap 2 is pressed between plastic screw post 1 and opponent's part 8, and produces clamping reinforing function to plastic screw post 1, produces gentle support effect to opponent's part 8.
As shown in Fig. 4 ~ Fig. 6, in another embodiment of the present utility model, it is screw pole reinforced embedded member 4 that structure is strengthened at described screw pole top, the outer side tube-wall of described screw pole reinforced embedded member 4 is in axial direction evenly distributed with multiple rectangle channel-shaped structure 5, scarfing unit on the outer side tube-wall of described screw pole reinforced embedded member 4 is the rectangle clamping structure 6 in the middle of adjacent two rectangle channel-shaped structures 5, and described screw pole reinforced embedded member 4 combines together with described plastic screw post 1.
In the present embodiment, in the production process of plastic screw post 1, screw pole reinforced embedded member 4 and plastic screw post 1 combine together, the barrel of screw pole reinforced embedded member 4 is gone out multiple channel-shaped structure 5, rectangle clamping structure 6 in the middle of adjacent two channel-shaped structures 5 matches with plastic screw post 1 and enhances the nested combination force of screw pole reinforced embedded member 4 and plastic screw post 1, avoid screw pole reinforced embedded member 4 to come off, facilitate later screw of beating and operate; In addition, running torque required when the rectangle clamping structure 6 in the middle of adjacent two channel-shaped structures 5 ensure that and plays screw, prevents screw pole reinforced embedded member 4 in dozen screw process to come off equally.
As shown in Figure 4, in another embodiment of the present utility model, the lower end of multiple rectangle channel-shaped structure 5 extends to the bottom of described screw pole reinforced embedded member 4.
