Description
Technical field
The utility model relates to a kind of multipoint mode EXPANSION ANCHOR BOLTS, belongs to hardware fastening technical field.
Background technique
EXPANSION ANCHOR BOLTS is a kind of special thread link used on pipeline, support, suspension bracket, bracket or equipment is fixing on the wall, floor, on post.The expansion-head of traditional EXPANSION ANCHOR BOLTS is generally a Rotary-table, one end of expansion sleeve is provided with some straight line seams, during use, turn nut, expansion tube is subject to straight line seam place distending after the extruding of nut, and in the sidewall of swollen tangible boring, thereby reaching fixing object, common people deserve to be called and state expansion fashion is linear expansion.
In recent years, fast development along with construction industry, novel wall material is shown one's talent, because mostly adopting foaming thermal-insulating, makes existing novel wall material, when adopting traditional EXPANSION ANCHOR BOLTS to be fixed, in screwing nut process, nut and screw rod easily rotate simultaneously, cannot be fastening, even can come off, do not have fixing effect.
Model utility content
The purpose of this utility model is for a kind of multipoint mode EXPANSION ANCHOR BOLTS is provided, when this multipoint mode EXPANSION ANCHOR BOLTS is in use subject to external force extrusion expansion, can take expansion tube expand as axial surrounding multiple spot, and be embedded in firmly in body of wall, can effectively stop like this nut and screw rod to rotate simultaneously, and the skidding occurring; On the expansion tube of this multipoint mode EXPANSION ANCHOR BOLTS, be provided with several breathing spaces, expansion effect is good, and bearing tension is large, difficult drop-off during use, and also simple in structure, easy to use.
In order to achieve the above object, the utility model is realized by following technological means:
A kind of multipoint mode EXPANSION ANCHOR BOLTS, it is comprised of the body of bolt, expansion sleeve, plain cushion, spring pad, nut, it is characterized in that: one end of the body of bolt is provided with bolt head, the other end of the body of bolt is provided with outside thread, the end that is provided with externally threaded one end on the body of bolt is provided with spanner fixing column, on the body of bolt, cover has expansion sleeve, on expansion sleeve, be along the circumferential direction provided with several slotted eyes, on the body of bolt, by outside thread, be fixed with nut, between nut and expansion sleeve, be provided with plain cushion, spring pad.
Described expansion sleeve is combined by two semicircle expansion tubes.
On described expansion sleeve, be provided with several breathing spaces, on breathing space, be along the circumferential direction provided with some slotted eyes.
Described slotted eye is shaped as circle, rectangle, ellipse.
The utility model mainly has following beneficial effect:
When 1, this multipoint mode EXPANSION ANCHOR BOLTS is in use subject to external force extrusion expansion, can take expansion tube expands as axial surrounding multiple spot, and be embedded in firmly in body of wall, can effectively stop like this nut and screw rod to rotate, and the skidding of appearance simultaneously.
2, on the expansion tube of this multipoint mode EXPANSION ANCHOR BOLTS, be provided with several breathing spaces, expansion effect is good, and bearing tension is large, difficult drop-off during use, and also simple in structure, easy to use.
