Abstract
An expansion bolt comprises a screw rod and a screw cap; the screw rod and the screw cap are fixedly connected and are internally provided with through holes; multiple closed holes are formed in the outer part of the through hole in the screw rod; dry ice is filled in the holes. The expansion bolt needs to be preserved at a low temperature at ordinary times. During use, the screw rod and a hole in the wall can be adhered together by an adhesive by injecting the adhesive into the through holes, the dry ice is heated and expanded, and the volume of the screw rod is also increased, so the expansion bolt is more reliable to fix; the parts of the expansion bolt are less and can be reliably fixed without the need of pulling.
Description
Technical field
The invention belongs to mechanical field, particularly a kind of EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS is a kind of conventional fixed component, for equipment part etc. is fixing on the wall, the principle of its effect is that the distortion by sleeve pipe completes, and such EXPANSION ANCHOR BOLTS need to have key and sleeve pipe two-part, cumbersome, and the drawing of need to exerting oneself just can be played fastening effect.
Summary of the invention
The object of this invention is to provide a kind of EXPANSION ANCHOR BOLTS, this EXPANSION ANCHOR BOLTS parts are few, do not need drawing to fix, and fixing firm.
The technological scheme adopting is:
, comprise screw rod and nut.
Its technological points is:
Screw rod and nut are fixedly connected.In screw rod and nut, offer through hole.
At inside screw, be positioned at through hole outside and be provided with a plurality of blind bores, in hole, be equiped with dry ice.
This EXPANSION ANCHOR BOLTS needs low temperature to preserve at ordinary times, in use, at through hole injecting glue, can make screw rod and hole on wall by together with glue bond, and dry ice expanded by heating also can increase the volume of screw rod, is fixing more firm.
Its advantage is:
This EXPANSION ANCHOR BOLTS parts are few, do not need drawing to fix, and fixing firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
, comprise screw rod 1 and nut 2.
Screw rod 1 and nut 2 are fixedly connected.In screw rod 1 and nut 2, offer through hole 3.
In screw rod 1 inside, be positioned at through hole 3 outsides and be provided with a plurality of blind bores 4, in hole 4, be equiped with dry ice.
