Abstract
The utility model discloses high-strength double end bolt and connect assembly, including studs and supporting nut, described nut is column type nut, on the outer peripheral face of column type nut, circumference offers the circle hole clipping for card dress knuckle buster, each hole clipping uniformly at intervals, at least the most axially offers the polygonal blind hole for inserting spin-ended spanner in one end of described studs in end face center.High-strength double end bolt of the present utility model connects assembly during installation and removal, the special spin-ended spanner utilizing shape adaptation inserts the rotation that can effectively avoid studs in polygonal blind hole, such that it is able to by knuckle buster by spinning column type nut screwing clamping on studs or removal, simultaneously, column type nut is used also to have certain anti-theft effect, high-strength double end bolt of the present utility model connection assembly overall structure is simple, assembly and disassembly convenient, efficiently solves the problem that prior art exists.
Description
Technical field
This utility model relates to a kind of high-strength double end bolt and connects assembly.
Background technology
Studs is that a kind of axially two ends all have threaded column securing member, is fixed member grip to be connected by the hex nut on the screw thread of stud two ends of the spinning respectively.Existing studs is mainly used in the installation fastening of main equipment.But due to the two ends of studs equal spinning nut, cause the installation and removal process of studs easily to occur that stud occurs skidding with nut rotation, cause the fastening of studs and dismounting to encounter difficulties.The most conventional stud installation and removal method is after two hex nuts in one end of studs are mutually carried on the back tightly, with spanner, the hex nut of the other end is tightened or removal again, adopt in this way, if when carrying on the back tight, strength is relatively low will not produce effect for two bolts, if back of the body clamp force amount is excessive, the screw thread of studs can be damaged, cause studs to be scrapped.
Utility model content
The purpose of this utility model is: provides one length in service life, mount and dismount convenient high-strength double end bolt connection assembly, to solve the problem that prior art exists.
The technical solution of the utility model is: a kind of high-strength double end bolt connects assembly, including studs and supporting nut, described nut is column type nut, on the outer peripheral face of column type nut, circumference offers the circle hole clipping for card dress knuckle buster, each hole clipping uniformly at intervals, at least the most axially offers the polygonal blind hole for inserting spin-ended spanner in one end of described studs in end face center.
The screw thread of described studs and nut is trapezoidal thread.
Described polygonal blind hole is regular hexagon blind hole.
It is to offer polygonal blind hole the end of studs is central axial that high-strength double end bolt of the present utility model connects assembly, during installation and removal stud, the special spin-ended spanner utilizing shape adaptation inserts the rotation that can effectively avoid studs in polygonal blind hole, such that it is able to by knuckle buster by spinning column type nut screwing clamping on studs or removal, simultaneously, column type nut is used also to have certain anti-theft effect, it is simple that high-strength double end bolt of the present utility model connects assembly overall structure, assembly and disassembly is convenient, efficiently solve the problem that prior art exists.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model high-strength double end bolt connects assembly.
Detailed description of the invention
High-strength double end bolt of the present utility model connects the specific embodiment of assembly as shown in Figure 1, it includes studs 1 and is respectively used to the spinning nut 2,3 at studs 1 two ends, wherein, nut 2,3 all uses column type nut, on the outer peripheral face of the nut 2,3 of column type, circumference offers the circle hole clipping 5 for card dress knuckle buster respectively, and each hole clipping 5 is uniform around the circle spacing.For avoiding studs 1 during installation and removal to rotate, it the most axially offers the polygonal blind hole 4 for inserting spin-ended spanner at the end face center of one end of studs 1, in the present embodiment, this polygonal blind hole 4 is regular hexagon blind hole, the aperture of this regular hexagon blind hole can be adaptive with existing conventional inner hexagon spanner, the inner hexagon spanner passing through to insert adaptation during installation and removal in polygonal blind hole 4 may insure that studs 1 will not be in company with rotation, such that it is able to utilize knuckle buster to tighten easily or removal column type nut 2,3.
Claims (3)
1. a high-strength double end bolt connects assembly, including studs and supporting nut, it is characterized in that, described nut is column type nut, on the outer peripheral face of column type nut, circumference offers the circle hole clipping for card dress knuckle buster, each hole clipping uniformly at intervals, at least the most axially offers the polygonal blind hole for inserting spin-ended spanner in one end of described studs in end face center.
High-strength double end bolt the most according to claim 1 connects assembly, it is characterised in that the screw thread of described studs and nut is trapezoidal thread.
