Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 2 to Fig. 5 is refer to, the anti-shearing packing ring that Fig. 2 is provided by a kind of specific embodiment in the utility model
Scheme of installation；Fig. 3 is another view of Fig. 2；Fig. 4 is the structural representation of anti-shearing packing ring；Fig. 5 is another view of Fig. 4.
In a kind of specific embodiment, anti-shearing packing ring provided by the utility model, including anti-shear ring 2, flange 5,
Flange 5 is connected with anti-shear ring 2, and flange 5 is abutted against near the surface of the side of anti-shear ring 2 with mounting seat, away from the side of anti-shear ring 2
Surface abuts against with mounted piece 6, and flange 5, can be with axially position anti-shear ring equivalent to ordinary flat packing ring of the prior art
2.The internal diameter of anti-shear ring 2 is identical with the diameter of shank of bolt 3, it is ensured that shank of bolt 3 and anti-shearing packing ring can be installed smoothly.Anti-shear ring
2 penetrate in the mounting holes 1 of mounting seat and are set in outside shank of bolt 3, and anti-shear ring 2 is interference fit with mounting hole 1, and the face of realization connects
Touch, when being sheared, effectively lift shear resistance, mounting hole 1 is not susceptible to damage or tears；Bolt is that line connects with anti-shear ring 2
Touch, but anti-shear ring 2 is wear-resisting, anti-shearing, realizes shearing resistance.During installation, anti-shearing packing ring is knocked in into mounting hole 1, Liang Zhewei with wooden mallet
Interference fit；Insertion bolt；Place mounted piece 6；Nut is installed, and is tightened.
Anti-shearing packing ring provided by the utility model, can significantly elevator bolt, mounting seat, mounted piece 6 it is anti-
Ability, lifting integrated connection intensity are cut, mounting hole 1 is not susceptible to damage or tears.
Above-mentioned anti-shearing packing ring is only a kind of preferred scheme, is specifically not limited thereto, on this basis can be according to reality
Needs are made with targetedly adjusting, and so as to obtain different implementation methods, mounting seat is hollow pipe mounting seat 4, hollow pipe
The aperture of the first mounting hole 1 that mounting seat 4 is contacted with bolt head is less than second that hollow pipe mounting seat 4 is contacted with mounted piece 6
The aperture of mounting hole 1, the aperture of the first mounting hole 1 is identical with the diameter of shank of bolt 3, and the second mounting hole 1 is with anti-shear ring 2 for interference is matched somebody with somebody
Close.That is, when anti-shearing packing ring plays a supportive role, first mounting hole 1 and second on the two sides of hollow pipe mounting seat 4 is installed
The aperture in hole 1 is different, and aperture is opened with bolt head contact surface, and aperture is identical with the diameter of shank of bolt 3；Other face wide-bore, diameter
Meet and the interference fit of anti-shear ring 2.Required axial force it is larger or install moment of torsion it is excessive or using rivet interlacement when, use shearing resistance
After cutting packing ring, axial supporting role can be played, it is to avoid hollow pipe mounting seat 4 is deformed because pretightning force is excessive, can risen
To the supporting role to hollow pipe, anti-shearing packing ring is especially in the stress hollow pipe that intensity is relatively low, and such as rectangular square tube is hollow
Fastening in structure is installed.
