Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in the figure, this eccentric combination device is used for connecting the member of composite furniture, and it is made up of expand locking post 1 and expansive screw 2; As shown in Figure 1, the locking post 1 that expands is a cylindrical body 11, the end face of cylindrical body 11 is a spanner 12, be that end face is made spanner shape (having the spanner function), have containing groove 13 and opening chute 14 in the circular arc at cylindrical body 11 circumferential surfaces own, interior containing groove 13 and opening chute 14 communicate, and the slot opening of the notch ratio open chute 14 of interior containing groove 13, interior containing groove 13 are the pull heads 211 for the metal pull bar 21 of inserting expansive screw 2.As shown in Figure 2, expansive screw 2 is made up of metal pull bar 21 and plastic cement expansion sleeve 22, and plastic cement expansion sleeve 22 is enclosed within on the metal pull bar 21; Metal pull bar 21 has pull head 211, and the rod ends below the pull head 211 are conehead (not drawing among the figure), and this conehead has draw-in groove 212 at the circumferential surface of pull head 211 in plastic cement expansion sleeve 22, and draw-in groove 212 is stuck in 14 li of opening chutes, and can slide at opening chute 14; Plastic cement expansion sleeve 22 is a hollow structure, and its circumferential surface is evenly distributed with axial expansion opening 222, and its endoporus is for slightly going up thin cone shape hole down, and the conehead of cone shape hole and metal pull bar 21 lower ends is slidingly matched, and there is outside thread the lower end of plastic cement expansion sleeve 22.
Working principle
Shown in Fig. 3-8, during assembling, the hole is stamped on the surface of member 3a and 3b respectively, wherein expansive screw 2 is installed in the hole of member 3a, plastic cement expansion sleeve 22 is installed in the hole of member 3b, containing groove 13 in the pull head 211 of metal pull bar 21 is injected then, and making draw-in groove 212 enter 14 li of opening chutes, rotating spanner 12 is under the effect of opening chute 14 off-centre, metal pull bar 21 is raised, at this moment the conehead below the metal pull bar 21 upwards slides, and under the effect of conehead, plastic cement expansion sleeve 22 inflation openings 222 vertically expands, plastic cement expansion sleeve 22 is fixed together with member 3b, thereby member 3a and member 3b are fitted together.When taking apart, spanner 12 is rotated in the opposite direction, conehead is to lower slider, and plastic cement expansion sleeve 22 restores to the original state under elastic reaction, and expansive screw 2 can be extracted in the hole of member 3a, thereby realizes separating of member 3a and member 3b, reaches the partition purpose.
