Abstract
The utility model relates to an expansion bolt with an inclined wall, which mainly solves the defect that the fastening strength of the currently used expansion bolt is not firm. A tapered expansion wedge on the upper end of the screw bolt is matched with an inner inclined wall on the upper end of each of expansion cylinders; both sides of each of the expansion cylinders are respectively provided with an easy expansion grooves; the length of each of the grooves can be adjusted according to the specification of the bolt and the required expansive force; the bolt is rotated to fasten the expansion wedge to make the two semicircular expansion cylinders gradually expanded to achieve a fastening purpose. The utility model has the advantages of reasonable design, convenient installation, high firmness and beautiful appearance after installation.
Description
Technical field
The utility model relates to bolt, particularly a kind of skew wall bolt of swelling installation gradually that utilizes.
Background technique
At present, EXPANSION ANCHOR BOLTS on the market is that this straight wall EXPANSION ANCHOR BOLTS dynamics is firm inadequately with the straight wall expansion cylinder of screw rod distending of nut turn termination band taper mostly.
Summary of the invention
The purpose of this utility model be to provide a kind of simple and reasonable, can make expansion cylinder distending, the powerful EXPANSION ANCHOR BOLTS of expansive force gradually.
The purpose of this utility model is achieved in that it includes expansion cylinder and screw rod, its upper end is a tapered expansion wedge 1, cooperate skew wall in expansion cylinder 2 upper ends, the both sides of expansion cylinder 2 have easy swollen groove 4, make expansion cylinder be two semicircles, insert expansion cylinder 2 with screw rod 3 and be connected, screw in the swelling wedge and make expansion cylinder distending gradually, thereby bolt is fixedly positioning in mounting hole with swelling wedge 1.
The flute length of above-mentioned easy swollen groove 4 is looked the specification and the required distending dynamics of bolt and is set.
Advantage of the present utility model is the installation strength height, and is practical and convenient, beautiful shape.
