Abstract
The utility model provides an expansion bolt, belongs to the technical field of expansion bolts, and aims to solve the problems that the existing expansion bolt is difficult to take out and strength is insufficient. The expansion bolt comprises a bolt seat and a bolt body. The bolt seat is provided with a groove, the bottom of the groove is provided with a through hole with inner screws. The bolt body is connected to the through hole in a screwed manner and can stretch in the groove by rotating the bolt body. The front end of the groove is hinged with an expansion rod, one end of the expansion rod is an arc end, the bolt body end penetrating the through hole is connected to the arc end of the expansion rod in a pressed manner, and axial movements of the bolt body drive the expansion rod to rotate. The expansion bolt has the advantages of fine practical effect, solid fixation, convenience for taking out and operating and the like.
Description
Technical field
The utility model belongs to the EXPANSION ANCHOR BOLTS technical field, refers in particular to a kind of EXPANSION ANCHOR BOLTS.
Background technique
Existing a kind of EXPANSION ANCHOR BOLTS, comprise bolt, expansion sleeve, wherein an end of bolt is provided with the section of swelling, utilize the section that swells of bolt that expansion sleeve is strutted, made the state of EXPANSION ANCHOR BOLTS and wall, plate body formation swelling, this kind of following defect of EXPANSION ANCHOR BOLTS ubiquity: one, the hollow state of expansion sleeve, intensity is not high, structure is firm not, and two, this kind of EXPANSION ANCHOR BOLTS be difficult to take out, can't reuse.
Summary of the invention
The purpose of this utility model is to provide a kind of EXPANSION ANCHOR BOLTS, and it makes EXPANSION ANCHOR BOLTS be convenient to install and dismounting by the design of scissors, and structure use simultaneously is firm.
The purpose of this utility model is achieved in that
EXPANSION ANCHOR BOLTS, comprise bolt block and bolt, it is characterized in that: on described bolt block, offer groove, the groove bottom land offers the through hole with internal thread, described bolt is screwed onto on through hole and can stretches in groove by rotating bolt, and the front end in described groove is hinged with expansion rod, and an end of described expansion rod is the cambered surface end, the described bolt end apical grafting through through hole is on the cambered surface end of expansion rod, and the axial motion of bolt drives the rotation of expansion rod.
In above-mentioned EXPANSION ANCHOR BOLTS, the described bolt end through through hole is the bulb shape, and the outer end of bolt is provided with the operation unit of shape changeable.
In above-mentioned EXPANSION ANCHOR BOLTS, be arranged with stage clip, pad on described bolt, nut.
