The specific embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Shown in Fig. 2 to 8, a kind of dismountable seat base that the utility model provides, comprise center support, center support comprises installing hole 10 and at least three support arms 20 that extend from installing hole 10 outward radials, installing hole 10 and support arm 20 are formed in one, the plastic parts that support arm 20 is formed in one, and the bottom surface of support arm 20 is provided with first screw hole 50, and the outer end of support arm 20 is bolted with adjutage 30 by first screw hole 50.Installing hole 10 is used for connecting the joint pin of base and seat.The material of center support is nylon or acrylonitrile-butadiene-styrene (ABS) plastics (ABS), adopts the mode of injection mo(u)lding to make.
Wherein, adjutage 30 is shaped as half slot or U-shaped groove (as shown in Figure 8).The adjutage 30 of this structure can significantly reduce the consumption of material, saves cost, and makes that the quality of base is slim and graceful, is convenient to carrying and transportation.
The cross section of support arm 20 be shaped as semicircle or U-shaped.Preferably, the shape of the cross section of support arm 20 is identical with the shape of adjutage 30, thereby makes the two assembling the time can coincide mutually, makes that whole understructure is firm, stress equalization.
One end of adjutage 30 is welded with brace 70, and brace 70 is provided with second screw hole 60 with first screw hole, 50 couplings.Concrete, brace 70 is welded on the groove edge of adjutage 30.
Be provided with two second screw holes 60 on each brace 70, the bottom surface of each support arm 20 is provided with two first screw holes 50.And two first screw holes 50 are connected by screw 40 respectively with two second screw holes 60.The mode that is spirally connected is convenient to dismounting and assembling.
Two first screw holes 50 are the nut that is embedded in the support arm 20.
The diameter of adjutage 30 is greater than the diameter of support arm 20, make support arm 20 can pass the space of adjutage 30 and connecting plate 70 compositions just, and make two first screw holes 50 of bottom surface of support arm 20 align respectively with two second screw holes 60 on the connecting plate 70, be convenient to the fixing of the two.
The length of support arm 20 makes support arm 20 can be set in adjutage 30 inside fully less than the length of adjutage 30, makes that the structure of whole base is elegant in appearance.
