Abstract
The utility model relates to the technical field of screw fittings, in particular to a combined check nut. The combined check nut comprises a screw and a screw cap which is arranged at the top of the screw. The nut is a large hexagonal nut, four small round holes provided with threads are evenly arranged in the screw cap of the large hexagonal nut at intervals, and four small nuts are respectively connected with the corresponding small round holes in a screwed manner; four iron wedges are arranged at the lower end of the screw cap, and the bottoms of the small nuts are in tight contact with the corresponding iron wedge. According to the structure that a workpiece is extruded through tight contact of the bottoms of the small nuts and the iron wedges inside the screw cap, the purposes of locking and looseness prevention can be achieved; compared with a conventional elastic washer, the combined check nut is good in looseness prevention effect, reusable, cost saving, convenient to mount and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to threaded connector technical field, is specifically related to Combined locknut.
Background technique
For the screw bolt and nut being threaded, because of its connection that is widely used in component easy to use simple in structure.Being most widely used of the screw bolt and nut of regular screw threads, after screw bolt and nut is locked mutually, under the effect of the factors such as vibration, nut is easily loosening, thereby causes Joint failure.In order to prevent nut loosening, people have taked a lot of measures, for example adopt spring washer locking, change the measures such as the locking and building rubber compound cap of pitch is locking.But for the above large-scale nut of 30mm, adopting after above-mentioned measure, its locking anti-loosing effect is still bad, and needs large-scale metal plate hand or boost bar just can tighten, and troublesome poeration, is not easy to dismounting.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, simple in structure, good, reusable, for convenience detach Combined locknut of locking anti-loosing effect.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: Combined locknut, comprise screw rod, be located at the nut of described screw tip, described nut is hexagonal big nut, on the nut of described hexagonal big nut, be evenly interval with threaded four small sircle holes, four primary nuts spin with described corresponding small sircle hole respectively, are provided with four wedge shape iron in the underpart of described nut, the bottom of described four primary nuts and corresponding wedge shape iron close contact.
The utlity model has following beneficial effect: Combined locknut described in the utility model, wherein, on the nut of hexagonal big nut, be evenly interval with threaded four small sircle holes, four primary nuts spin with corresponding small sircle hole respectively; The utility model adopts said structure, by the wedge shape iron close contact in bottom and the nut of primary nut, extruding workpiece, thereby reach locking, locking object, and its locking, anti-loosing effect are good, compared with traditional elastic washer, this nut is reusable, cost-saving, and be convenient to install convenient disassembly.In addition, the utlity model has the features such as reasonable in design, simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1 and Figure 2, Combined locknut, comprise screw rod 1, be located at the nut 2 on described screw rod 1 top, described nut is hexagonal big nut, on the nut 2 of described hexagonal big nut, be evenly interval with threaded four small sircle holes 3, four primary nuts 4 spin with described corresponding small sircle hole 3 respectively, are provided with four wedge shape iron 5 in the underpart of described nut 2, the bottom of described four primary nuts 4 and corresponding wedge shape iron 5 close contacts.In the present embodiment, because designing slope rake angle, inner wedge iron 5 is greater than nut angle, when having workpiece 6 vibrations to occur, wedge shape iron close contact in the bottom of primary nut 4 and nut 2, extruding workpiece 6, produces lifting tension force, thereby reaches perfect locking, anti-loosing effect.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
