Abstract
The utility model relates to an expanding anchor. The expanding anchor comprises a sleeve body and a striking nail, wherein one end of the striking nail is movably arranged in the sleeve body, a ring flange is arranged at one end of the sleeve body, and the inside of the ring flange is tapered. The expanding anchor is characterized in that at least one pair of clamping surfaces is arranged on the ring flange. When the expanding anchor is used for fixing an object in a mounting hole on a wall surface, the sleeve body expands in volume under the extrusion action of the striking nail to clamp the object on the wall surface; and when the object is dismounted, a tool is used for applying force to the pair of the clamping surfaces to rotate the object, and then the sleeve body expands the mounting hole, so that the object can be taken out conveniently, and is prevented from being damaged. Moreover, an embossing part which is provided with a plurality of staggered flower patterns or a plurality of spaced ring nicks is arranged on the outer wall surface of the sleeve body to increase the effect when the sleeve body is fixed.

Embodiment
Your, only, please consult with description collocation accompanying drawing for making auditor can know the content of understanding the utility model.
See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, the sectional view during for the three-dimensional exploded view of the utility model preferred embodiment and assembling thereof, and the view during attaching/detaching.Shown in figure, the expansible anchor 1 of the utility model comprises a sleeve body 11 and a nail hitting 12, in order to an object 2 is fixedly held to the surface of a metope or ceiling board 3.
Wherein the end processed with metal material of this sleeve body 11 is the round tube shape structure body of closed shape; And the two ends of this sleeve body 11 are respectively a closed end 111 and an open end 112; And the outer wall of this closed end 111 is provided with a pair of trench digging 1111; The center of this open end 112 holding part 1121 that extended internally, these holding part 1121 front ends are connected with this trench digging 1111, and this holding part 1121 extends to this closed end 111 and presents gradually-reducing shape along this open end 112; Therefore; Be close to the external diameter of the external diameter of this open end 112, and have a ring flange 1122, and this ring flange 1122 of present embodiment is provided with three pairs of clamping faces 1123 and form the hexagon shape in this open end 112 greater than contiguous this closed end 111; Yet also can be two pairs of clamping faces 1123 and form rectangular-shapedly, be provided with connect using an instrument 4 (like spanner) and rotate this sleeve body 11; It should be noted that the quantity of these a plurality of clamping faces 1123 on this ring flange 1122 also can be a pair of or two pairs, be provided with connecting this instrument 4 through particular design.When it uses; It is a perforation 21 and stretch in the mounting hole 31 of this metope or ceiling board 3 of this sleeve body 11 being passed this object 2; Utilize this ring flange 1122 to be pressed on the periphery of this perforation 21 again,, avoid its unsteady problem in fixing back to increase its pressure force fixedly the time.In addition; Outer wall in this closed end 111 is provided with an embossed portion 1112, and shown in figure, this embossed portion 1112 is crisscross arranged for multi-pattern; So after these closed end 111 volumetric expansions, and can be by means of the frictional force of these embossed portion 1112 increases with this mounting hole 31 surfaces.
The two ends of this nail hitting 12 are respectively first end 121 and one second end 122, and these first end, 121 confession activities are arranged in this holding part 1121, and this second end 122 exposes to this sleeve body 11 and is formed with a stress surface 1221 that supplies hammering.During use; Utilize this stress surface 1221 of this nail hitting 12 of iron hammer hammering; This first end 121 is moved along the direction of this holding part 1121; Because external diameters of this holding part 1121 inner contiguous these open ends 112 are greater than external diameters of contiguous this closed end 111, thus can make this closed end 111 receive extruding and the volumetric expansion of this first end 121, and clip is in this mounting hole 31.
As shown in Figure 5; These closed end 111 outer wall of the utility model are provided with this embossed portion 1112; And this embossed portion 1112 is that a plurality of ring indentations are with equidistance or the setting of non-equi-spaced apart; These a plurality of ring indentations all are ring inclined plane shape structure and are easy to guiding and penetrate towards the direction of this closed end 111, are unfavorable for the reverse hook design outwards withdrawed from, thereby can effectively promote the grasping force of clip in these mounting hole 31 (not shown) the time.
The above; Be merely the preferred embodiment of the utility model; Be not in order to limiting the scope that the utility model is implemented, thus those skilled in the art, or be familiar with this technology and done equivalence or variation person easily; The equalization of under spirit that does not break away from the utility model and scope, being done changes and modifies, and all should be covered by in the claim of the utility model.
