Abstract
This utility model provides multi-functional copper core bolt, it includes the bolt body of cylinder, the extension of bolt body top forms nut, nut top has raised up stair-stepping apical ring, apical ring center is provided with recessed internal messing groove, and internal messing trench bottom is passed down through nut and extends to bolt body bottom；Bolt body surface is provided with concavo-convex knurled rib stricture of vagina, and the height of knurled rib stricture of vagina is 0.5 ~ 2mm；Bolt body outer peripheral face top is provided with two and forms tangent plane to the cannelure being centrally recessed into, the turning of both sides, bolt body bottom, and the tangent plane degree of depth is 1 ~ 5mm.This programme can realize grafting, positioning function by tangent plane, and knurled rib stricture of vagina can realize anti-skidding, and internal messing groove realizes linkage function.
Description
Technical field
This utility model relates to bolt technical field, refers in particular to multi-functional copper core bolt.
Background technology
Bolt is a kind of general Hardware fitting, and existing bolt is made up of head and screw rod (with externally threaded cylinder) two parts, needs and nut screw connection, for being fastenedly connected two parts with through hole.This mode is only used for common connection.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of easy for installation, firm, the multi-functional copper core bolt of grafting, location can be realized.
For achieving the above object, technical scheme provided by the utility model is: multi-functional copper core bolt, it includes the bolt body of cylinder, the extension of bolt body top forms nut, nut top has raised up stair-stepping apical ring, apical ring center is provided with recessed internal messing groove, and internal messing trench bottom is passed down through nut and extends to bolt body bottom；Bolt body surface is provided with concavo-convex knurled rib stricture of vagina, and the height of knurled rib stricture of vagina is 0.5 ~ 2mm；Bolt body outer peripheral face top is provided with two and forms tangent plane to the cannelure being centrally recessed into, the turning of both sides, bolt body bottom, and the tangent plane degree of depth is 1 ~ 5mm.
The described tangent plane degree of depth is less than the degree of depth of cannelure.
Described internal messing groove is concentric with bolt body, and internal messing groove inwall is provided with engagement screw thread.
This utility model is after using such scheme, a kind of abnormity connecting bolt is provided, the outer surface annular knurl of copper core bolt, and two cannelures are had in middle and upper part, and relative both sides carry out cutting formation tangent plane in bottom, the most easy for installation, and carry out inlay card by cannelure and equipment, thus realize firm function is installed.Can realize grafting, positioning function by tangent plane, knurled rib stricture of vagina can realize anti-skidding, and internal messing groove realizes linkage function.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is cut-away view of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, multi-functional copper core bolt described in the present embodiment includes the bolt body 1 of cylinder, the extension of bolt body 1 top forms nut 2, nut 2 top has raised up stair-stepping apical ring 3, apical ring 3 center is provided with recessed internal messing groove 4, described internal messing groove 4 is concentric with bolt body 1, and internal messing groove 4 inwall is provided with engagement screw thread, it is passed down through nut 2 bottom internal messing groove 4 and extends to bolt body 1 bottom；Bolt body 1 surface is provided with concavo-convex knurled rib stricture of vagina 5, and the height of knurled rib stricture of vagina 5 is 0.5 ~ 2mm；Bolt body 1 outer peripheral face top is provided with two and forms tangent plane 7 to the cannelure 6 being centrally recessed into, the turning of both sides, bolt body 1 bottom, and tangent plane 7 degree of depth is 1 ~ 5mm, and described tangent plane 7 degree of depth is less than the degree of depth of cannelure 6.The present embodiment provides a kind of abnormity connecting bolt, the outer surface annular knurl of copper core bolt, and two cannelures are had in middle and upper part, and relative both sides carry out cutting formation tangent plane in bottom, the most easy for installation, and carry out inlay card by cannelure and equipment, thus realize firm function is installed.Can realize grafting, positioning function by tangent plane, knurled rib stricture of vagina can realize anti-skidding, and internal messing groove realizes linkage function.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
