Abstract
The utility model relates to a nut technical field specifically is an abrasionproof decreases hex nut structure, and it is reducing wear effectively, increase of service life, and it includes the body, a serial communication port, it has the step hole to open on the body, the path part inner wall in step hole sets up the internal thread, the big footpath part inner wall in step hole is the smooth surface, step hole opening part is provided with the abrasionproof packing ring, the abrasionproof packing ring is elastomeric element, the opening in step hole is outer along having seted up annular dovetail, the abrasionproof packing ring through annular forked tail fixture block with the annular dovetail the cooperation install in on the body, it has the size to be greater than to open on the abrasionproof packing ring the through -hole of step hole path part, abrasionproof packing ring mid portion inlay card in the big footpath in step hole part.
Description
Technical field
This utility model is related to nut technical field, specially a kind of anti-wear hexagonal (hexagon)nut structure.
Background technology
Nut is and screw, bolt, screw phase to the use of cooperation, plays and connects the parts that fastening mechanism acts on, hexagonal
Nut is common, as shown in figure 1, it is twisted by handss or spanner is realized tightening or unscrewed, because nut may frequency
Numerous dismounting, easily occurs wearing and tearing with contact surfaces such as screw bolts, reduces service life.
Content of the invention
In order to solve the above problems, this utility model provides a kind of anti-wear hexagonal (hexagon)nut structure, and it can effectively subtract
Less wear, increases the service life.
Its technical scheme is such：A kind of anti-wear hexagonal (hexagon)nut structure, it includes body it is characterised in that described
Stepped hole, the path internal partial wall setting female thread of described stepped hole, the large diameter portion inwall of described stepped hole are had on body
For shiny surface, at described stepped hole opening, it is provided with abrasionproof packing ring, described abrasionproof packing ring is elastomeric element, the opening of described stepped hole
Mouth outer offers annular dovetail slot, and described abrasionproof packing ring passes through the cooperation installation of annular dovetail fixture block and described annular dovetail slot
On described body, described abrasionproof packing ring has the through hole that size is more than described stepped hole path part, described abrasionproof packing ring
Mid portion inlay card is in described stepped hole large diameter portion.
It is further characterized by, and the medial wall angle of inclination of described annular dovetail slot is 60 °.
After structure of the present utility model, due to abrasionproof packing ring being mounted with body, only wear and tear in use
Abrasionproof packing ring, body is substantially unaffected, abrasionproof packing ring only need to change after damaging one new, without replacing hexagonal spiral shell
Cap body, annular dovetail slot not only makes stablizing of abrasionproof packing ring installation with the cooperation of annular dovetail fixture block, changes simultaneously
Also more convenient, extend the service life of hexagonal (hexagon)nut body.
Brief description
Fig. 1 is existing nut structure top view；
Fig. 2 is this utility model nut generalized section.
Specific embodiment
As shown in Figure 2, a kind of anti-wear hexagonal (hexagon)nut structure, it includes body 1, body 1 has stepped hole 2, step
The path internal partial wall setting female thread 3 in hole 2, the large diameter portion inwall of stepped hole 2 is shiny surface, arranges at stepped hole 2 opening
There is abrasionproof packing ring 4, abrasionproof packing ring 4 is elastomeric element, and the opening outer of stepped hole 2 offers annular dovetail slot 5, abrasionproof packing ring 4
It is installed on body 1 by the cooperation of annular dovetail fixture block 6 and annular dovetail slot 5, abrasionproof packing ring 4 has size and is more than step
The through hole 7 of hole 2 path part, prevents from affecting the normal use of nut, abrasionproof packing ring 4 mid portion inlay card fits in stepped hole 2
Large diameter portion.The medial wall angle of inclination of annular dovetail slot 5 is 60 °, and too big abrasionproof packing ring 4 fixation of angle is insecure, and angle is too
Little, remove inconvenience.
