Preferably, described the first fixing part also comprises one first stiffening rib, the rectangular triangle of described the first stiffening rib, the edged surface always of described the first stiffening rib is fixedly connected with a side of described the first plate, and another right angle face of described the first stiffening rib is fixedly connected with described the first stiffening plate; Described the second fixing part also comprises one second stiffening rib, the rectangular triangle of described the second stiffening rib, and the edged surface always of described the second stiffening rib is fixedly connected with described the second plate.
Preferably, this safe fastener is plastic construction.
Preferably, one the 3rd stiffening rib that is connected between described the second stiffening plate and described joint.
Pass through technique scheme, the safe fastener that the utility model provides, by its first plate and the second inserting board, be located in upper arm, and be fixed in column by its bar shaped inserted block, its first stiffening plate and the second stiffening plate play the effect that increases upper arm intensity, thereby locking upper arm and column, prevent that upper arm from coming off from column.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the structural representation of the disclosed a kind of safe fastener of the utility model embodiment and upper arm and column assembling;
Fig. 2 is the structural representation of the disclosed upper arm of the utility model embodiment;
Fig. 3 is the structural representation of the disclosed a kind of safe fastener of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Shown in Figure 3, the utility model provides a kind of safe fastener, comprising:
The first fixing part 1, the second fixing part 2, joint 3, the first fixing part 1 and the second fixing part 2 are located at respectively the two ends of joint 3, and be fixedly connected with joint 3, joint 3 is V-shaped, the first fixing part 1 comprises one first plate 11 and vertical the first stiffening plate 12 being fixed on the first plate 11 1 sides, the end of the first plate 11 is provided with a hooked scarf 13, the second fixing part 2 comprises one second plate 21, bar shaped inserted block 22, the second stiffening plate 23, the second stiffening plate 23 is vertically fixed on a side of the second plate 21, bar shaped inserted block 22 is vertically fixed on the another side of the second plate 21.
The first fixing part 1 also comprises the rectangular triangle of one first stiffening rib 14, the first stiffening rib 14, the first stiffening rib 14 always edged surface be fixedly connected with a side of the first plate 11, another right angle face of the first stiffening rib 14 is fixedly connected with the first stiffening plate 12; The second fixing part 2 also comprises the rectangular triangle of one second stiffening rib 24, the second stiffening rib 24, and the edged surface always of the second stiffening rib 24 is fixedly connected with the second plate 21.The first stiffening rib 14 and the second stiffening rib 24 can play the effect that increases safe fastener intensity, make safe fastener structure more firm, not easy-rupturing.
This safe fastener is plastic construction, and wherein, joint has certain elasticity, can be in its plastic range in-draw.
One the 3rd stiffening rib 25 that is connected between the second stiffening plate 23 and joint 2, plays the effect of the fastener intensity that further tightens security.
As shown in Figure 1-2, the safe fastener that the utility model provides in use, need be used in combination with upper arm 40 and column 50.Upper arm 40 comprises square hole 401, symmetrically arranged the first draw-in groove 402, symmetrically arranged the second draw-in groove 403, bar-shaped trough 404, grab 405; On one side of column 50, be provided with fixed hole 501.Grab 404 is fastened on the lower limb of positioning hole 501, thereby upper arm 40 is fixed on column 50.
