Abstract
The utility model relates to an expansion bolt, comprising a screw rod, a screw nut and a casing tube. The tail side of the screw rod is provided with a key; when the key is screwed tightly, the key can be clamped tightly with the groove on the casing tube; the phenomenon of sliding oppositely and rotating all the time is not easy to occur.
Description
The utility model relates to a kind of link, in particular for the link of installation accessories on fixed buildings or miscellaneous equipment.
Now general EXPANSION ANCHOR BOLTS all has three primary components, and one for tail end is that the frustum middle part is the screw rod of screw thread for garden post front end, and two is nut, and it three has the sleeve pipe of groove for tail end.Such EXPANSION ANCHOR BOLTS has individual shortcoming, and screw rod and nut have slightly not that up time very easily makes nut and screw rod work day and night, can not be with the sleeve pipe distending, and bolt can not be fastening, so that installed insecure by the dress object.
The purpose of this utility model provides a kind of non-slip in rundown process, even the EXPANSION ANCHOR BOLTS that screw thread has some setbacks and also can not work day and night.
The utility model is a kind of key EXPANSION ANCHOR BOLTS that has, and having afterbody is that the frustum middle part is the sleeve pipe that the threaded screw rod of garden post front end, nut and tail end have groove, it is characterized in that screw rod tail side frustum partly has key.
The utility model screw rod tail has key, and the sleeve pipe afterbody has groove, and both tighten not slide relative easily when tightening, difficult working day and night.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the front view of embodiment's screw rod;
Fig. 3 is the side view of embodiment's screw rod.
Embodiment is the metallic EXPANSION ANCHOR BOLTS, and by screw rod 1, nut 2 and sleeve pipe 3 constitute, for fastening getting partly also is furnished with pad, packing ring admittedly.The afterbody of sleeve pipe 3 is uniform-distribution with four grooves 5, and screw rod tail side has and groove strong with number, and strong position is relative with the position of groove.
Claims (2)
1, a kind of have a strong EXPANSION ANCHOR BOLTS, has afterbody and be the frustum middle part and for the threaded screw rod of garden post front end, nut and tail end the sleeve pipe of groove is arranged, and it is strong to it is characterized in that the screw rod tail frustum partly has.
2, bolt according to claim 1 is characterized in that the number of package of screw rod tail equates that with the groove number of sleeve pipe afterbody the position is relative.
