Consult Fig. 8, it is for showing the present invention 1 the 3rd preferred embodiment, mainly is that main body according to aforementioned second preferred embodiment changes and is made as two and separates partly, and it includes a body 302 and an intermediate base 304 was arranged with this body in 302 minutes.
Consult Fig. 9, its schematic representation for showing that connection fittings 10 of the present invention are connected with a tubular object 56.The joint of the body 12 of these connection fittings 10 is set to spiral joint 58, and this tubular object 56 has the joint 58 that a connecting part 60 is provided with spiral joining hole and this body 12 and can interconnect fixing.In addition, further can cooperate a sleeve 61 to be located at the junction of this body 12 and tubular object 56, and axially corresponding with this tubular object 56 after body 12 is pulled an angle, and can this sleeve 61 be socketed on the plug spare 20 of axial correspondence, shown in figure 11.
Consult Figure 10, it is for showing the connection fittings 400 of the present invention's the 4th preferred embodiment, and it comprises that a body 402 has a junction 404, and a pair of aforesaid plug-in package 14 is articulated in the opposite end of this body 402 respectively.Wherein, this joint 404 has a button portion 406.
Consult Figure 11, it for example connects two objects of a drawer appliance 62 for showing that connection fittings of the present invention are used to connect two objects.This drawer appliance 62 includes a pair of drawer bogie side frame 64, a drawer-bottom board 65, a drawer panel 66 and drawer back of the body frame 67; Use and form a basic drawer inner space; And a pair of aforesaid tubular object 56 of can arranging in pairs or groups is installed on top, this space, and forms higher material-putting space.Wherein, this can be expressed as the relation between one first object and one second object respectively between drawer bogie side frame 64 and this drawer panel 66, and it can interconnect fixing with aforementioned the 4th embodiment's connection fittings 400.For example: a pair of plug-in package 14 of these connection fittings 400 is connected with this drawer panel 66; Then the joint 404 of the body 402 through these connection fittings 400 is pulled an angle; That is these body 402 relative these plug-in package 14 rotations one angles; This button portion 406 and this drawer bogie side frame 64 snapping are each other fixed, and with the connection through these connection fittings 400, it is fixing to make this drawer bogie side frame 64 and this drawer panel 66 be able to each other be connected.In addition; This is between tubular object 56 and this drawer panel 66; Also can be expressed as the relation between one first object and one second object respectively; It can be provided with aforementioned connection fittings shown in Figure 9 10, that is the joint of the body 12 of these connection fittings 10 is set to spiral joint 58, and this tubular object 56 has a connecting part 60 and is connected combination with the joint 58 of this body 12.Then; Being preset with mounting hole through this drawer panel 66 supplies the plug-in package 14 of these connection fittings 10 to insert; And make these tubular object 56 relative these drawer panels 66 pull an angle; Can make said interlock convex body 52 generations of the said expanding piece 18 of this plug-in package 14 expand outwardly the inwall location, hole of biting this drawer panel 66, it is fixing to make this tubular object 56 and this drawer panel 66 be able to each other be connected.
Consult Figure 12; It is for showing that connection fittings of the present invention are used to connect two objects; For example connect a hinge 68 and a door-plate 74, also can be expressed as the relation between one first object and one second object respectively, wherein; This hinge 68 has a pair of perforation 70, and a pair of plug-in package 14 pass this hinge 68 respectively this 70 and one body 12 of boring a hole is articulated with a driving piece 17 each other.Wherein, the joint of this body 12 is set to a pulling part 72.During use; Be preset with two slotted eyes 76 through this door-plate 74, in order to supply this respectively plug-in package 14 inserted, afterwards; Through the pulling part 72 of pulling this body 12, can make this that the expanding piece 18 of plug-in package 14 and 76 of the slotted eyes of this door-plate 74 are formed snap-in location.
According to above explanation, but the enhancement effect and the advantage of knowledge capital invention promptly are:
When plug-in package a. of the present invention is inserted in the hole of an object; Rotate an angle through pulling relative this plug-in package of this body; This expanding piece can respond the squeezing action power of this body; Extruding space through this expanding piece is squeezed, and the said interlock convex body of this expanding piece is produced expand outwardly and the hole inwall of biting this object is tightly fixed.When desiring in the hole of this object, to unload this plug-in package; Need only oppositely pull this body; This expanding piece promptly no longer receives the squeezing action power from this body, and the said interlock convex body of this expanding piece can be broken away from by inwall from the hole of this object, no longer bites the inwall in its hole.Therefore, connection fittings of the present invention can assemble easily and pull down use.
B. the expanding piece of connection fittings of the present invention is for be socketed between this inserting member and this body versatilely; Therefore; After the hole dismounting for several times of this expanding piece with respect to same target; Still can rotate the radial angle that changes said interlock convex body arbitrarily with respect to this inserting member, make the said interlock convex body of this expanding piece still can each other tight interlock fix with the hole inwall diverse location of this object through this expanding piece, and reusable.
Though the present invention describes with reference to current specific embodiment; But those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; Under the situation that does not break away from spirit of the present invention, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of the application's claims in connotation scope of the present invention.
