The utility model provides a technical scheme, during the installation, use with axial regular polygon recess matched with spanner, with double -end stud's one end screw in installation threaded hole, then the reload is tight at double -end stud's other end cover top nut and lemon by the connecting piece, can increase substantially assembly efficiency, also can ensure assembly quality simultaneously.
Description
Technical field
The utility model is related to technical field of fastening, especially relates to a kind of studs.
Background technology
Securing member is to be fastenedly connected with and apply extremely wide class machine components.In various machineries, equipment, car
, ship, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc. above, it can be seen that miscellaneous tight
Firmware.Its feature is that description is various, and performance purposes is different, and standardize, seriation, unitized kind of degree also pole
High.Studs is also stud, double-threaded screw or double threaded screw, and the most frequently used form of studs is two in the market
There is screw thread at end, and centre is polished rod, is generally used for mining machinery, bridge, automobile, motorcycle, boiler steel structure, tower crane, large span
Steel construction and heavy construction etc..Mounting means typically has two kinds：Using special threaded assembly tool by the one of studs
End screws in installs screw thread in the hole, then installation tool is exited from studs, refills connected piece and nut；Stepped up with bias
Device, clamps studs unthreaded portion, first screws in one end of studs and installs screw thread in the hole, then refills connected
Part and nut.Above two mode, is usually limited it is difficult to ensure assembling quality by factors such as part design itself and assembly tools
Difference, efficiency of assembling is relatively low.
Utility model content
In order to overcome the defect of prior art, the utility model provides one kind to be conducive to ensureing assembling quality, improves assembling
The studs of efficiency.
In order to solve above-mentioned technical problem, the utility model provides a kind of studs, has isometrical screw thread including two ends
Screw rod；It is arranged on one end of described screw rod or the axial regular polygon groove at two ends；Join with described axial regular polygon groove
Close the end cap connecting, part or all of described end cap is inserted in described axial regular polygon groove；The middle part of described screw rod
There is the light bar segment without screw thread；The diameter of described light bar segment is less than the diameter of two ends thread segment, and described light bar segment has section
For square section of regular polygon, described square section of external diameter of a circle is less than the diameter of two ends thread segment；Described axial direction is just polygon
Connected in star is more than the pyramid connected in star of the bottom portion of groove length of side for end surface side length.
The studs providing as further improved technology scheme, the utility model, described axial regular polygon groove
For positive triangle, square or regular hexagon groove.
The studs providing as further improved technology scheme, the utility model, the outer surface of described screw rod has
Zinc coat.
In the case of not conflicting, above-mentioned improvement project can be implemented alone or in combination.
The technical scheme that the utility model provides, during installation, using the spanner with axial regular polygon fit depressions, will
One end of studs screws in installs screw thread in the hole, then refills connected piece, covers top nut simultaneously in the other end of studs
Lemon is tight, can increase substantially efficiency of assembling, also can ensure assembling quality simultaneously.
Brief description
Accompanying drawing is used for providing further understanding to of the present utility model, constitutes the part of the application, of the present utility model
Schematic description and description is used for explaining the utility model, does not constitute to improper restriction of the present utility model.In accompanying drawing
In：
Fig. 1 is the structural representation of embodiment one studs；
Fig. 2 is the left view structural representation of Fig. 1；
Fig. 3 is the structural representation of embodiment two studs；
Fig. 4 is the left view structural representation of Fig. 3.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail.
Embodiment one：Studs as depicted in figs. 1 and 2, has the screw rod 1 of isometrical screw thread including two ends, screw rod 1
One end is provided with axial regular hexagon groove 2；The middle part of screw rod 1 has the light bar segment 3 without screw thread, and light bar segment 3 has section and is
Square section of square, the diameter of light bar segment 3 is less than the diameter of two ends thread segment, and square section of external diameter of a circle is less than two ends
The diameter of thread segment.
Embodiment two：Studs as shown in Figure 3 and Figure 4, has the screw rod 1 of isometrical screw thread including two ends, screw rod 1
One end is provided with axial regular hexagon groove 2, and the pyramid that regular hexagon groove 2 is more than the bottom portion of groove length of side for end surface side length is recessed
Groove；The middle part of screw rod 1 has the light bar segment 3 without screw thread, and light bar segment 3 has square section that section is square, light bar segment 3
Diameter be less than the diameter of two ends thread segment, square section of external diameter of a circle is less than the diameter of two ends thread segment, pyramid connected in star
Be conducive to improving the intensity of studs.Also be there is the end cap being connected with described axial regular polygon groove 2, described end cap
Part or all insert described axial regular polygon groove 2 in.Setting end cap, is conducive to protecting studs, makes end
More attractive.
Alternatively, the studs that the utility model provides, the outer surface of described screw rod 1 has zinc coat.
During installation, using the spanner with axial regular polygon fit depressions, for example, match with axial regular hexagon groove 2
The inner hexagon spanner closing, one end of studs is screwed in and installs screw thread in the hole, then refill connected piece, in studs
The other end covers top nut and lemon is tight, can increase substantially efficiency of assembling, also can ensure assembling quality simultaneously.
The utility model is not limited to above preferred embodiment, also can limit in the utility model claim and specification
Spirit in, carry out conversion and the improvement of various ways, same technical problem can be solved, and obtain expected technique effect,
Therefore do not repeat.Those of ordinary skill in the art can from the utility model disclosure directly or all schemes of associating,
As long as within the spirit that claim limits, falling within protection domain of the present utility model.
