Detailed description of the invention

As shown in Figure 1 to 4, assembled electric cable protector straight pin attachment structure of the present utility model, Including straight pin 1 and the axle clamp back-up ring 2 that matches with straight pin 1, described straight pin 1 includes cylinder Sell body 1-1, be arranged on the locking cap 1-2 of end, straight pin body 1-1 one end and be arranged on cylinder On pin body 1-1 other end circumference and for being connected together the draw-in groove 1-3 of axle clamp back-up ring 2；Described axle Folder back-up ring 2 include the back-up ring body 2-1 of annular and be inclined on back-up ring body 2-1 inner ring and For snapping in the multiple elastic card 2-2 in draw-in groove 1-3.

As depicted in figs. 1 and 2, in the present embodiment, described straight pin body 1-1 is provided with draw-in groove 1-3 End, one end be provided with round platform 1-4.

As depicted in figs. 1 and 2, in the present embodiment, described locking cap 1-2 is shaped as hemispherical.

As shown in Figures 2 and 3, in the present embodiment, described back-up ring body 2-1 inner ring is positioned at two Part between elastic card 2-2 is provided with convex edge 2-3.

As shown in Figure 2, Figure 3 and Figure 4, in the present embodiment, the quantity of described elastic card 2-2 is Four, the quantity of corresponding described convex edge 2-3 is four.

In conjunction with Fig. 5 and Fig. 6, when this utility model uses, an assembled electric cable protector, need Using four these straight pin attachment structures, four straight pin attachment structures are respectively used to electric cable protector The left side at main body 3-1 two ends half folder 3-2 and right half folder 3-3 is connected in electric cable protector main body 3-1, Specifically, after a left side half folder 3-2 or right half folder 3-3 is docked in electric cable protector main body 3-1, First straight pin 1 is penetrated after left half folder 3-2 or right half folder 3-3 docks with electric cable protector main body 3-1 In the connecting hole formed, then axle clamp back-up ring 2 is stuck in draw-in groove 1-3, owing to elastic card 2-2 is It is inclined on back-up ring body 2-1, therefore, when the side that elastic card 2-2 can bend along it After snapping in draw-in groove 1-3, just it is not easy to be removed, it is ensured that axle clamp back-up ring 2 is at draw-in groove 1-3 In be reliably connected, and by back-up ring body 2-1 inner ring between two elastic card 2-2 Part convex edge 2-3 is set, it is possible to compensate the gap between back-up ring body 2-1 inner ring and draw-in groove 1-3, Make axle clamp back-up ring 2 relatively reliable with the connection of draw-in groove 1-3.

The above, be only preferred embodiment of the present utility model, not makees this utility model any Limit, every according to this utility model technical spirit, above example is made any simple modification, Change and equivalent structure change, all still fall within the protection domain of technical solutions of the utility model.
