Abstract

The invention discloses a kind of rotating expansion bolt, the outer arm of the expand tube of this rotating expansion bolt has two or more equidistant U-shaped stripings, the U-shaped body formed, to Zhang Qu outside expand tube wall, forms the anti-rotation card of wing.Two gussets axially arranged and the rectangle draw-in groove matched with it is set up at the head of EXPANSION ANCHOR BOLTS.Have cylindrical hole at the neck of screw rod, the corresponding part of expand tube both sides has draw-in groove, and the stage casing of cylindricality pin is inserted in cylindrical hole, and two ends are stuck in draw-in groove.The sidewall of screw head neck has groove, has two axis with the expand tube wall head end of its corresponding part and striping is set.The invention has the beneficial effects as follows: utilize the present invention effectively can solve EXPANSION ANCHOR BOLTS in fastener cycle with the phenomenon of pulling in rotating.

Description

A kind of rotating expansion bolt

Technical field

The present invention relates to a kind of rotating expansion bolt.

Background technique

In use often there is the situation being greater than expand tube external diameter that prefabricated hole inner arm diameter is too much in existing EXPANSION ANCHOR BOLTS, again because the expand tube of EXPANSION ANCHOR BOLTS and prefabricated hole inner arm are without large frictional connection, connect without linking mutually again between expand tube and bolt, thus cause EXPANSION ANCHOR BOLTS rotate with spanner in fastener cycle and nut cannot be screwed into, EXPANSION ANCHOR BOLTS cannot be expanded, there is the unstable problem of indivedual EXPANSION ANCHOR BOLTS, namely lost time, made again EXPANSION ANCHOR BOLTS not reach due effect.

Summary of the invention

First technical problem that the present invention will solve prevents expand tube with the phenomenon that spanner rotates in fastener cycle, and second technical problem that the present invention will solve prevents screw rod in fastener cycle with the phenomenon that spanner rotates.

The concrete scheme that the present invention solves first technical problem is: on the outer arm of the expand tube of this rotating expansion bolt, have two or more equidistant U-shaped stripings, and the U-shaped body formed, to Zhang Qu outside expand tube wall, forms the anti-rotation card of wing.

The concrete scheme that the present invention solves second technical problem is: the symmetrical gussets setting up two axial settings on the side arm up and down of screw head, are provided with the rectangle draw-in groove matched with this gusset width in corresponding part, expand tube top.

Have a cylindrical hole at the neck of screw rod, the corresponding part of expand tube both sides has draw-in groove, the stage casing of cylindricality pin is inserted in cylindrical hole, two ends are stuck in draw-in groove.

The sidewall of screw head neck has groove, has two axis with the expand tube wall head end of its corresponding part and striping is set.

The invention has the beneficial effects as follows: utilize the present invention effectively can solve EXPANSION ANCHOR BOLTS in fastener cycle with the phenomenon that spanner rotates.

Embodiment

Example 1

As shown in Figure 1, have two or more equidistant U-shaped stripings 3 at expand tube 2, the U-shaped body formed, to Zhang Qu outside expand tube 2 wall, forms the anti-rotation card 4 of wing.

Example 2

As shown in Figure 2, on the upper and lower sidewall of screw rod 1 head, the symmetrical gussets 5 setting up two axial settings, are provided with the rectangle draw-in groove 6 matched with this gusset 5 width in corresponding part, expand tube 2 top.

Example 3

As shown in Figure 3, have a cylindrical hole 7 at the neck of screw rod 1, the corresponding part of expand tube 2 both sides has rectangle draw-in groove 6, and the stage casing of cylindricality pin 8 is inserted in cylindrical hole 7, and two ends are stuck in rectangle draw-in groove 6.

Example 4

As shown in Figure 4, the sidewall of screw rod 1 head and neck has groove 9, have two axis with the expand tube 2 wall head end of its corresponding part and striping 10 is set.

Bar shaped tube wall 11 between striping 10 is curved inwardly in the groove 9 being stuck in screw rod 1 head and neck during use.
