Namely described first connection section 240 and the angle of described rivet nut 210 are in the scope of 45 degree to 135 degree, as being specifically as follows 90 degree, this angle scope is conducive to described first connection section 240 and described 2nd connection section 250 to match, with hook body and ring portion, the connection realizing body of wall.
It is appreciated that, described angle value is specifically as follows 90 degree, the angle that can also be other is such as 105 degree, and it is to restriction of the present utility model that the concrete angle value of described first connection section 240 and the 2nd connection section 250 and described rivet nut 210 should not be construed.
Specifically, described first hook body 260 and described 2nd hook body 270 can tilt to the direction away from described pin body.
Described first hook body 260 and described 2nd hook body 270 can match with described first ring portion 220 and the 2nd ring portion 230, body of wall has the inclination radian that slight, such that it is able to play certain barrier effect so that the possibility that built-up type dog comes off from body of wall is lower.
Details refer to Fig. 4, and dog 200 can also comprise described first barb 280 and described 2nd barb 290. Described first barb 280 is connected near the side of described rivet nut 210 with described first hook body 260, and described 2nd barb 290 is connected near the side of described rivet nut 210 with described 2nd hook body 270.
Described first barb 280 and described 2nd barb 290 can be connected near the side of described rivet nut 210 with described first hook body 260 and described 2nd hook body 270 respectively, instead of it is arranged on the side away from described rivet nut 210 of the first hook body 260 and the 2nd hook body 270, it is possible to reduce the possibility that user is drawn wound when reinforcing wall by barb.
Specifically, the end of described first barb 280 and the end of described 2nd barb 290 are specifically as follows tapered end. The end of conical by its shape makes described first barb 280 and described 2nd barb 290 in the trend more thin the closer to end. When carrying out the fixing operation of barb insertion body of wall, the barb end of taper can reduce resistance during built-up type dog insertion body of wall. And the described barb end of taper can produce bigger obstruction trend when there being the trend being pulled out, thus prevent deviating from of built-up type dog.
It is appreciated that, the end of described first barb 280 and the end of described 2nd barb 290 can be tapered end, the end that can also be other shapes is such as cylinder-shaped end, and it is to restriction of the present utility model that the end of described first barb 280 and described 2nd barb 290 should not be construed.
Described rivet nut 210 can be pointed in the end of described first barb 280, and described rivet nut 210 can also be pointed in the end of described 2nd barb 290.
Described rivet nut 210 is all pointed in the end of described first barb 280 and described 2nd barb 290, it may also be useful to person is in one's hands more difficult by described first barb 280 and described 2nd barb 290 strokes wound when holding, thus improves the safety in utilization of this built-up type dog.
Details refer to Fig. 5, the end of described first barb 280 has radian, the end of described first barb 280 bends near the direction of described first hook body 260, the end of described 2nd barb 290 has described radian equally, and the end of described 2nd barb 290 bends near the direction of described 2nd hook body 270.
Described first barb 280 and described 2nd barb 290 with radian both can well prevent described built-up type dog from deviating from from body of wall, can avoid again drawing hinder user because barb being too sharp-pointed.
It is appreciated that, the radian of described first barb 280 and described 2nd barb 290 is specifically as follows 60 degree, can also be other angles such as 90 degree, it is to restriction of the present utility model that the concrete radian of described first barb 280 and described 2nd barb 290 should not be construed.
Specifically, described rivet nut 210, first ring portion 220, the 2nd ring portion 230, first connection section 240, the 2nd connection section 250, first hook body 260 and what the 2nd hook body 270 all can be made up of steel. The built-up type dog that steel are made is longer for work-ing life, not easily damages.
It is appreciated that, described rivet nut 210, first ring portion 220, the 2nd ring portion 230, first connection section 240, the 2nd connection section 250, first hook body 260 and the 2nd hook body 270 can also be made up of other materials such as rigid plastics, and it is to restriction of the present utility model that the manufactured materials of described built-up type dog should not be construed.
