Description
Technical field:
The utility model belongs to bolt, especially a kind of upset bolt.
Background technique:
Present commercially available EXPANSION ANCHOR BOLTS, its installment work is loaded down with trivial details, needs first fastening nut, after being anchored at screw rod in the boring on the basis, nut being unscrewed pulled down again, again the material that needs anchoring is placed on the screw rod, fastening nut then could be good the material anchoring, and installation rate is slow; In addition, this EXPANSION ANCHOR BOLTS is after anchoring, and its body cannot disassemble and repeat to install and use, and this must make troubles to installment work and later overhauling, and also causes waste simultaneously.
Summary of the invention:
The purpose of this utility model be to provide a kind of quick and easy for installation, can dismantle the upset bolt that uses repeatedly.
Technical solution of the present utility model is such, comprise by screw rod, nut, card key, spring, stay cord, the screw rod anchoring has cavity on the position, the card key is housed in the cavity, screw rod anchoring position another side has teeth groove, has spring to back down between card key lever and the screw rod anchoring position, has through hole on the screw rod, be fixed on the pulling-on piece of screw tip after stay cord on the card key lever passes through hole, the boss on the pad manufactures with basis boring internal diameter.
The utility model has the advantages that simple in structurely, installation is time saving and energy saving, and is convenient and swift, can dismantle repeatedly and use.
Description of drawings:
Fig. 1 is an overall structure plan view of the present utility model.
Fig. 2 installs the main sectional view of looking for overall structure of the present utility model.
Among Fig. 1, Fig. 2, screw rod anchoring position (1), card key (2), card key lever (3), spring (4), stay cord (5), boss (6), pad (7), nut (8), pulling-on piece (9), screw rod (10), through hole (11), teeth groove (12), card (13), basis boring (14).
Embodiment:
Most preferred embodiment of the present utility model is such, shown in accompanying drawing, have the circular arc cavity on one side at screw rod anchoring position (1), the side of cavity is fixed with card (13), prevent that card key (2) from deviating from, moving card key (2) is housed in the cavity, screw rod anchoring position (1) another side has teeth groove (11), there is spring (4) to back down between card key lever (3) and the screw rod anchoring position (1), make card key (2) keep opening from state with respect to screw rod anchoring position (1), have through hole (11) on the screw rod (10), after passing through hole (11), stay cord (5) on the card key lever (3) is fixed on the pulling-on piece (9) on screw rod (10) top, pulling-on piece (9) is lived and is connected the top of screw rod (10), and the boss (6) on the pad (7) manufactures different specifications with basis boring internal diameter.Same on the basis of EXPANSION ANCHOR BOLTS, also can make the expansion hook.
During installation, boring (14) on the basis is earlier put the EXPANSION ANCHOR BOLTS of corresponding specification in the hole (14) into, has card key (2) and teeth groove (12) to be clamped on boring (14) lining, and the boss (6) on the pad (7) blocks hell fastening nut (8) and gets final product.When needing dismounting, unscrew nut (8), pulling pulling-on piece (9) can be pulled down repeated use to EXPANSION ANCHOR BOLTS by stay cord (5) pulling card key (2) pressure spring (4).
