Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
As an embodiment of the present utility model, as shown in figs. 1 to 6, this chek bolt, nut set comprise nut 2, bolt 1 and the snap ring 3 for bolt 1 and nut 2 being fastenedly connected, wherein nut 2 inside is provided with the first groove 201 for holding snap ring 3, and the head of bolt 1 is provided with for by matching the incompatible bolt 1 that prevents to the second groove 101 of outward turning with snap ring 3; Snap ring 3 is arranged in the first groove 201 of nut 2 inside, and when bolt 1 is screwed in nut 2, the edge of the external diameter 301 of snap ring is positioned at the first groove 201 of nut 2, and the edge of the inner side path 303 of snap ring is positioned at the second groove 101 of bolt 1 head.In embodiment of the present utility model, when using this chek bolt, nut set, snap ring 3 is placed in the first groove 201 of nut 2 inside, and when bolt 1 is screwed in nut 2, snap ring 3 can by bolt 1 and nut 2 organically united, serve and prevent bolt 1 and nut 2 nut 2 when shaking from holding caducous effect.
The inner side of snap ring 3 is conical surface, and the inner side path 303 of snap ring is less than the external diameter 102 of the second groove of bolt 1 head, and is greater than the internal diameter 103 of the second groove.So when being equipped with in the nut 2 of snap ring 3 by bolt 1 screw-in, the edge of the inner side path 303 of snap ring being then positioned at the second groove 101 of bolt 1 head, and then can stop outwards outwarding winding of bolt 1, bolt 1, nut 2 not being loosened and departs from.Large footpath 302, the inner side of snap ring is greater than the external diameter 102 of the second groove of bolt 1 head again, facilitates bolt 1 and is screwed in nut 2.
Alternatively, in another embodiment of the present utility model, as depicted in figs. 1 and 2, snap ring 3 is the spring card made by spring steel, so can ensure when bolt 1 is screwed in nut 2, the large footpath, inner side 302 of snap ring and the inner side path 303 of snap ring greatly variable, and then allow being screwed into of bolt 1, and the large footpath 302, inner side of snap ring and the inner side path 303 of snap ring can restore to the original state enter the second groove 101 of bolt 1 head at snap ring 3 after, the inner side path 303 of snap ring is finally made to be less than the external diameter 102 of the second groove of bolt 1 head thus to stop deviating from of nut 2.
Alternatively, in another embodiment of the present utility model, as seen in figures 3-5, the external diameter 301 of snap ring is greater than the internal diameter 203 of the first groove of nut 2 inside again, and snap ring 3 can not be dropped out outside the groove of nut 2 in normal state.
Alternatively, in another embodiment of the present utility model, as shown in Figure 1, the thickness 104 of the thickness 304 of snap ring and the thickness 204 of the first groove of nut 2 inside and the second groove of bolt 1 head, all with identical Spielpassung, makes between bolt 1 and nut 2 more fastening.
Alternatively, in another embodiment of the present utility model, as shown in Figure 2, snap ring 3 is provided with for preventing bolt 1 to the opening portion 305 of outward turning, prevents bolt 1 in the environment of fierceness concussion automatically to screw out in nut 2.
Alternatively, in another embodiment of the present utility model, as shown in Figure 5, bolt 1 head is provided with chamfering and is greater than 45 degree, and bolt 1 can easily be entered in snap ring 3.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
