Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of technical field of the splicing screw rod with locking function.
[background technique]
Screw rod is that outer surface is cut spiral fluted cylinder or cut the circular cone of Conical Spiral Groove, and screw rod has different heads, has outer-hexagonal screw rod, large flat screw rod, hexagon socket head cap screw etc.; Traditional screw rod is all generally an overall structure, if the length of screw rod is inadequate, we just can not lengthen it, are therefore unfavorable for the Collection and utilization of expense screw rod; Traditional screw rod does not generally offer spacing draw-in groove, because a lot of screw rod is all use on machine, after starting the machine, can there is a little vibration in machine, when using nut of a specified duration to come loose even to depart from screw rod, cause important impact will to like this normal operation of machine to wearing screw rod.
[summary of the invention]
The purpose of this utility model is exactly to solve the problems of the prior art, a kind of splicing screw rod with locking function is proposed, the utility model is by making sliceable screw-rod structure screw rod, enable us to according to different needs, screw rod lengthened and shortens, thus adding the versatility of different length screw rod; Limiting stopper, also by having offered limit stoper on traditional screw rod, therefore after we are nut screwing clamping, is then punctured in spacing draw-in groove by the utility model, even if how machine vibrates nut again and also can not come loose or slippage like this.
For achieving the above object, the utility model proposes a kind of splicing screw rod with locking function, comprise splicing screw rod bottom fitting, splicing screw rod intermediate portion, splicing screw rod end-fitting, connection bump, connecting groove, spacing draw-in groove and limiting stopper, described splicing screw rod intermediate portion by connection bump and connecting groove respectively with splicing screw rod bottom fitting with splice screw rod end-fitting and be connected, the connecting end of described splicing screw rod bottom fitting is provided with connection bump, the two ends of described splicing screw rod intermediate portion are respectively equipped with connection bump and connecting groove, the connecting end of described splicing screw rod end-fitting is provided with connecting groove, described splicing screw rod bottom fitting, splicing screw rod intermediate portion and splicing screw rod end-fitting are equipped with spacing draw-in groove, described limiting stopper is arranged on the inside of spacing draw-in groove.
As preferably, described splicing screw rod bottom fitting, splicing screw rod intermediate portion and splicing screw rod end-fitting are equipped with screw thread, and splicing screw rod bottom fitting, splicing screw rod intermediate portion and splicing screw rod end-fitting three be connected after screw thread communicate.
As preferably, described connection bump and connecting groove have the screw thread silk tooth be meshed, described splicing screw rod bottom fitting, splicing screw rod intermediate portion are identical with the size of connecting groove with all connection bumps on splicing screw rod end-fitting.
As preferably, described splicing screw rod bottom fitting is up/down perforation with splicing the spacing draw-in groove that screw rod intermediate portion is opened, the spacing draw-in groove that described splicing screw rod end-fitting is opened also for getting through the bottom surface of splicing screw rod end-fitting, nut used of the present utility model also has the groove corresponding with spacing draw-in groove.
The beneficial effects of the utility model: the utility model, by screw rod is made sliceable screw-rod structure, enables us to, according to different needs, lengthen and shorten nut to screw rod, thus adds the versatility of different length screw rod; Limiting stopper, also by having offered limit stoper on traditional screw rod, therefore after we are nut screwing clamping, is then punctured in spacing draw-in groove by the utility model, even if how machine vibrates nut again and also can not come loose or slippage like this.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
