Abstract
The utility model relates to an expansion bolt which still comprises a screw rod, and the outer sleeve of the screw rod is provided with an expanding sleeve whose lower end is provided with at least more than one opening guide groove. The lower end part of the screw rod stretching out the expanding sleeve is provided with a conical nut, and a corresponding convex block is arranged on the nut and is positioned in the opening guide groove of the expanding sleeve. The utility model is characterized in that the outer surface of the expanding sleeve is provided with a slightly convex block, and the opening end of the opening guide groove of the expanding sleeve is arranged into a bottle-neck shape. The outer part of the expanding sleeve of the utility model with the structural characteristic is provided with the slightly convex block, which can ensure the screw rod not to slide when rotating corresponding to the expanding sleeve, and because the opening end of the opening guide groove is arranged into a bottle-neck shape, the conical nut can be ensured to be suspended on the expanding sleeve without separating at any time, providing guarantee to the rotation, the propulsion and the positioning of the screw rod and having convenient storing and carrying.
Description
The utility model is about a kind of EXPANSION ANCHOR BOLTS.
Traditional expansion bolt (nail) generally adopts the outer suit expansion set of conical screw (popular name screw), in the using process, vertically move the purpose that the expansion set that gos deep into the swelling overcoat reaches fastening assembly by screw rod in expansion set, its shortcoming is that screw rod usually can not guarantee to submerge among the expansion set and influences function of use and attractive in appearance; Deficiency at above-mentioned EXPANSION ANCHOR BOLTS (nail) existence, notification number provides a kind of anti-slip expantion bolt for internal nut for CN2192757X, be characterized in screw rod by the band cap, expansion set and tapered cup nut are formed, expansion set is provided with more than one openings lead (recessed) groove at least, tapered cup nut is the thumb nut of band ear, after the assembling, its ear is stuck in guiding (recessed) groove of expansion set, the EXPANSION ANCHOR BOLTS of this structural feature, although solved the not exposed shortcoming externally of screw rod, but there is inconvenience and structural unreasonable in the using process, at first be that tapered cup nut does not separate with expansion set when being connected with screw flight, make when installing screw rod usually look for inaccurate precession position, secondly to be expansion set drive the nut rotation at screw rod advances often because of expansion set skids and makes operation increase man-hour.
The purpose of the utility model be to overcome go up the deficiency that prior art exists and provide a kind of and prevent to skid, EXPANSION ANCHOR BOLTS that installation conditions is low, easy to operate.
This EXPANSION ANCHOR BOLTS still includes screw rod, screw jacket is equipped with expansion set, the expansion set lower end is provided with more than one openings lead groove at least, the underpart that screw rod stretches out expansion set is provided with tapered cup nut, nut is provided with the openings lead groove that corresponding projection places expansion set, its characteristics are that the expansion set outer surface is provided with the dimpling piece, and the openings lead slot opening end of expansion set is set as the bottleneck shape.
The dimpling piece that its expansion set of the utility model of tool said structure characteristics is provided with outward, can guarantee that screw rod is non-slip when expansion set rotates, openings lead slot opening end is set as the bottleneck shape can be guaranteed whenever tapered cup nut all is suspended on the expansion set and not separate, give security for the screw rod rotation advances the location, it is also convenient that other storage band uses.
Further illustrate the utility model below in conjunction with description of drawings.
Fig. 1 is the utility model example structure sectional view.
Fig. 2 is expansion set and tapered cup nut separated state view.
Wherein, 1: screw rod, 2: expansion set dimpling piece, 3: expansion set, 4: openings lead groove, 5: tapered cup nut, 6: nut projection, 7: processing groove.
As shown in the figure, the screw rod 1 of present embodiment is the common screw of a band cap, in fact, do not have hat-shaped structure but have the screw rod of spiral shell cutter groove can be yet as screw rod 1 of the present utility model, screw rod 1 is enclosed within the expansion set 3, and expansion set 3 is provided with the dimpling piece, in openings lead groove 4 the utility model that expansion set 3 underparts are provided with both as the guiding groove of tapered cup nut 5, also, be provided with the inflation openings groove certainly in addition and also can as expansion set 3 inflation openings grooves.The mechanism of present embodiment is as follows, when screw rod 1 rotation, is enclosed within tapered cup nut 5 on the expansion set 3 owing to be threaded with screw rod 1, and it is moved to longitudinal direction, and distending expansion set 3 makes its location thereupon.
