Abstract
The utility model relates to an upset bolt with taper sleeve, comprising a standard unit countersunk head bolt and a conical nut. The utility model is characterized in that a taper sleeve which is provided with a narrow groove in axial direction is arranged on the external cone of the conical nut. The utility model has the advantages of simple structure, low cost, reliable work, convenient installation, convenient dismounting and good invisibility. The upset bolt with taper sleeve is suitable for mass production and can be widely used for the connecting and fixing of wooden components, and besides, the upset bolt with taper sleeve can also be used for the connecting and fixing of plastic and metal pieces.
Description
A kind of EXPANSION ANCHOR BOLTS with tapered sleeve belongs to the device of fastening or fixed component.
In wooden furniture is made, general employing square hole of being connected and fixed of member Vertical direction or timber wedge structure are assembled, and, increase the intensity of its combination in their mating face coated with adhesive.Though the structure of this form can satisfy the usability of furniture, the processing technology complexity is not easy to produce in enormous quantities, and because furniture is non-disconnectable structure, it is big to take up room, and directly influences transport power and carrying.Though some furniture use or transportation in can partly fold, but adopt the hinge of inconvenient dismounting to connect, influence attractive in appearancely, using scope is subjected to certain limitation.
The purpose of this utility model is to provide a kind of and is connected and fixed use for wooden furniture, and the EXPANSION ANCHOR BOLTS of the good band tapered sleeve of hidden performance.
Inventive principle of the present utility model is as follows.Threaded end at the standard piece countersunk screw is equipped with tapered cup nut.On the outer conical surface of tapered cup nut, be fitted with the tapered sleeve identical with the nut tapering, the periphery of tapered sleeve is processed into roughened surface, and it axially has a narrow groove.During assembling, countersunk screw passes the circular hole of link, be placed in another link hole in the band tapered sleeve tapered cup nut be connected, screw countersunk screw and can fix two links.
The utlity model has simple in structure, with low cost, reliable operation, easy accessibility, the characteristics of good concealment are suitable for producing in enormous quantities, after forming series product, can be widely used in being connected and fixed of wooden pieces, also can be used for being connected and fixed of plastics and metalwork.
Accompanying drawing is a structural representation of the present utility model.
Threaded end in standard piece countersunk screw (1) is equipped with tapered cup nut (2), and tapered sleeve (3) is loaded on the outer conical surface of tapered cup nut (2).
Embodiment of the present utility model is a kind of EXPANSION ANCHOR BOLTS that is used to be connected and fixed the band tapered sleeve that wooden arm-chair uses, and the lumps of wood that is connected is of a size of 30 * 30mm, and the standard piece countersunk screw is M6 * 50, and the standard taper of tapered cup nut is 1:7～3, and middle footpath is 14mm.The tapering of tapered sleeve endoporus is identical with tapered cup nut.Narrow groove width 1mm.
