Abstract
The utility model discloses a drawing type expansion screw bolt used for installing stationary members in a general project. The utility model is composed of a screw nut, an expansion sleeve and a screw rod. The screw nut forms a cone shape and connects with one end with a deformation fracture of the expansion sleeve and the screw rod is arranged in the conical screw nut from the other end of the expansion sleeve. Compared with the existing expansion screw bolt, the utility model which has the advantages of reliable fixing performance, neat and beautiful appearance of the fixed objects without exposed screw rod, etc. is especially suitable for the present interior decoration and finishing project.
Description
The utility model relates to a kind of bolt that is used for fixing member in common engineering.
At present, employed when installing and fixing certain member is the EXPANSION ANCHOR BOLTS that we are familiar with very much, and its fixed performance is reliable, uses also very convenient.Yet there is a fatal shortcoming in it: after promptly installing and fixing, expose long one section screw mandrel in the outer end of the member that is fixed, and fix tightly more, the part of exposing is just long more, not only is in the way but also not attractive in appearance.Simultaneously, EXPANSION ANCHOR BOLTS even the member that is fixed is removed, also is difficult for its taking-up after loading onto.After the protective grating of being installed in the both sides, street as present each large, medium and small city is removed, just expose countless screw mandrels on the road surface, though through spending the processing of manually bending, but still can't thoroughly remove and become hidden danger on the road surface.
Provided by the utility model is exactly that a kind of fixed performance is reliable, the outside neat appearance of fixture, the Drawing type upset bolt that no screw mandrel is exposed.
The utility model is made up of nut, expansion sleeve, screw rod, and its nut is taper, has an end that is out of shape fracture with expansion sleeve and joins, and screw rod is then packed in this tapered cup nut by the other end.
The utlity model has following two big advantages: the no screw mandrel in (1) fixation surface is exposed, neat appearance; (2) in case fixation is removed, the screw rod of backing out is also reusable, turns bane into boon.
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the expansion sleeve unfolded drawing.
Describe the structure characteristic and the installation and application thereof of this Drawing type upset bolt in detail below in conjunction with accompanying drawing.
1 is tapered cup nut among Fig. 1, and 2 is expansion sleeve, and available iron plate, aluminium sheet or similar material are made, and 3 is screw rod.4 are the distortion fracture among Fig. 2, and 5 are the roll extrusion tool marks, can suitably shorten the length of expansion sleeve as required.Tapered cup nut and expansion sleeve have an end that is out of shape fracture and join among Fig. 1, in screw rod is then packed tapered cup nut into from the expansion sleeve the other end.
When using this bolt member, on stationary plane, have openning hole earlier, its aperture equates with the expansion sleeve external diameter, tapered cup nut one end is put into the hole, the another port of expansion sleeve is concordant with stationary plane, and it is no longer loosening that rotating screw bolt, tapered cup nut borrow the pulling force of screw rod to be drawn in the expansion sleeve stretching.The screw rod of back-outing is aimed at the expansion running-on with the hole on the fixture, inserts screw rod, tightens, and promptly reaches fixing purpose.After fixed block is removed, only stay an aperture on the stationary plane, after screw rod takes off, repair slightly, reusable again.Both convenient attractive in appearance, economy again.
The utility model uses extensively, and fixed performance is reliable, and is convenient attractive in appearance, especially in the house decoraton fitting-out work, is aided with some special parts, can play the inaccessible effect of common EXPANSION ANCHOR BOLTS.
