Abstract
The utility model discloses a kind of fast nut assembly, overcome the deficiency of conventional nut assembly, catered to the custom using conventional nut and packing ring, use occasion is equal to the use occasion of conventional nut and packing ring, and technology capability is high.Its technological scheme is: fast nut assembly comprises fast nut, bolt, nut collar, wherein fast nut is provided with convex, nut collar is provided with step hole, and in the assembling of fast nut, nut collar and bolt, the convex of fast nut stretches in the step hole of nut collar.Such design only needs to change a little the locking element of traditional nut-screw, not increasing manufacture cost when any add-on parts just greatly can reduce actual use, serving positive realistic function for promoting the use of.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of fast nut assembly.
Background technique
Two parts be connected wherein because of design needs when screw rod (bolt) is connected fastening with nut can be exchanged, and cause the change of thickness.When fastening thin part, because part thickness differs greatly, screw rod (bolt) can not be exchanged, then nut needs to screw in longer distance arrival locked position, wastes time and energy.
In addition, for the screw rod (bolt) needing larger distance adjustment also can carry out finely tuning to adapt to different operating mode in length and nut assembly, the time screwed out is screwed in longer.Also can run into the fastening occasion that screw thread is positioned at equal diameter cylindrical body intermediate section (conventional nut cannot be screwed into).
The fastening piece of traditional screw bolt and nut can not well be satisfied the demand in aforesaid application.
Model utility content
Below provide the brief overview of one or more aspect to provide the basic comprehension to these aspects.Detailed the combining of this not all aspect contemplated of general introduction is look at, and both not intended to be pointed out out the scope of key or decisive any or all aspect of elements nor delineate of all aspects.Its unique object is the sequence that some concepts that will provide one or more aspect in simplified form think the more detailed description provided after a while.
The purpose of this utility model is to solve the problem, provide a kind of fast nut assembly, overcome the deficiency of conventional nut assembly, cater to the custom using conventional nut and packing ring, use occasion is equal to the use occasion of conventional nut and packing ring, and technology capability is high.
The technical solution of the utility model is: the utility model discloses a kind of fast nut assembly, comprise fast nut, bolt, nut collar, wherein fast nut is provided with convex, nut collar is provided with step hole, and in the assembling of fast nut, nut collar and bolt, the convex of fast nut stretches in the step hole of nut collar.
According to an embodiment of fast nut assembly of the present utility model, the end face that nut collar moves to its planar end surface and fixture along bolt is fitted.
According to an embodiment of fast nut assembly of the present utility model, fast nut is with the position of its eccentric opening close touching nut collar along bolt to fast nut.
According to an embodiment of fast nut assembly of the present utility model, fast nut diametrically moves to and makes the partial thread hole of fast nut and the thread engagement of bolt, in the process screwing fast nut, the convex of fast nut stretches into the step hole of nut collar, until the bottom surface of convex end face laminating step hole.
According to an embodiment of fast nut assembly of the present utility model, screw rod contains the long bolt that screw thread is in cylindrical bar neutral position.
The utility model contrast prior art has following beneficial effect: the fast nut in the utility model and nut collar are inserted in bolt, fast moving is to the position needing locking, nut centering (i.e. nut and screw coaxial), the little convex on nut screws in be tightened to the shallow step hole of nut collar again.Such design only needs to change a little the locking element of traditional nut-screw, not increasing manufacture cost when any add-on parts just greatly can reduce actual use, serving positive realistic function for promoting the use of.
Accompanying drawing explanation
Figure 1A, 1B show the structural drawing of the preferred embodiment of fast nut assembly of the present utility model.
Fig. 2 A, 2B, 3A, 3B show the assembly process schematic diagram of fast nut assembly of the present utility model.
Embodiment
After the detailed description of reading embodiment of the present disclosure in conjunction with the following drawings, above-mentioned feature and advantage of the present utility model can be understood better.In the accompanying drawings, each assembly is not necessarily drawn in proportion, and the assembly with similar correlation properties or feature may have identical or close reference character.
The structure of the preferred embodiment of fast nut assembly of the present utility model see Figure 1A and 1B, this be fastening after state.Fast nut assembly comprises fast nut 1, bolt 2 (being stay bolt in the present embodiment), nut collar 3, wherein fast nut 1 is provided with convex 10 in the axial direction, the position corresponding to convex of nut collar 3 is provided with step hole 30, in the assembling of fast nut 1, nut collar 3 and bolt 2, the convex 10 of fast nut 1 stretches in the step hole 30 of nut collar 3, radially gets loose to prevent fast nut.When the bottom surface of the end face laminating step hole 30 of convex 10, fastener 41 and 42 is screwed.Screw rod in the utility model contains the situation that screw thread is in the long bolt in cylindrical bar neutral position.
Fig. 2 A, 2B, 3A, 3B show the assembly process of fast nut assembly of the present utility model.First Fig. 2 A and 2B, fastener 41 and 42 is in predetermined mounting point, and nut collar 3 is inserted in bolt 2, is inserted in bolt 2 with the eccentric opening (being usually greater than thread size about 0.1mm) on fast nut 1.
Then see Fig. 3 A and 3B, the end face that nut collar 3 moves to its planar end surface and fastener 41 along bolt 2 is fitted.Fast nut 1 is with the position (i.e. position shown in Fig. 3 B) of its eccentric opening close touching nut collar along bolt 2 fast moving to fast nut.Fast nut 1 is diametrically moved to and makes the thread engagement of its partial thread hole and bolt 2 (i.e. fast nut and bolt coaxial), the convex 10 of fast nut 1 stretches into the bottom surface of the interior the step hole 30 until end face of convex 10 is fitted of step hole 30 of nut collar 3, tighten, the state after tightening is the state shown in Figure 1A, 1B.
Thering is provided previous description of the present disclosure is for making any person skilled in the art all can make or use the disclosure.To be all apparent for a person skilled in the art to various amendment of the present disclosure, and generic principles as defined herein can be applied to other variants and can not depart from spirit or scope of the present disclosure.Thus, the disclosure not intended to be is defined to example described herein and design, but the widest scope consistent with principle disclosed herein and novel features should be awarded.
