Abstract
Provided is a modified structure of an antitheft nut which is only provided with antitheft steel balls in grooves, belonging to the field of mechanical products. The utility model aims to provide an antitheft nut which is provided with an antitheft steel cylinder in each of the grooves of the antitheft nut. When the product is horizontally placed, two semi-crescent-moon shaped grooves with one end deep and the other end shallow are opened on the inner side wall of the nut with a protruding part and symmetrically on the same cross section; a soft annular ring is fixedly arranged at the end face of the protruding part of the nut; the antitheft steel cylinder is arranged in each of the grooves; an assembling pad is plugged into the inner hole of the nut; finally , the assembled nut equipped with the protruding part and the grooves can be screwed on a bolt after the bolt is penetrated through the hole of a workpiece, and the bolt pushes the assembling pad out of the inner hole of the nut. The utility model not only has the advantages of the antitheft nut which is only provided with antitheft steel balls in grooves, but also has the advantages of more stable, durable, and reliable antitheft function.
Description
Technical field: the utility model belongs to the machinery product category, the anti-theft nut structure-improved of more definite a kind of antitheft steel ball of only packing in groove of saying so.
Background technique: existing some electric power facilities that use and post and telecommunications facilities need adopt the anti-theft measure of anti-dismounting.The many employings anti-theft nut that now is used for open-air anti-dismounting facility such as electric power tower and post and telecommunications iron tower.At present the anti-theft nut that uses mainly is to utilize the contact surface of antitheft parts (comprising antitheft steel ball or antitheft steel cylinder) and bolt in the nut groove to produce frictional force to stop nut to retreat and become flexible, causing nut is nut intactly to be unloaded down after tightening on the bolt again, thereby has played antitheft effect.The big more frictional force that then produces between the two of contact surface of antitheft parts in the anti-theft nut groove (antitheft steel ball or antitheft steel cylinder) and bolt is big more, the retaining of anti-theft nut, anti-loosening function is strong more, anti-theft feature is stable more, lasting more, reliable more.Prove that by experiment the structure of inserting antitheft steel ball in nut groove is much littler than the frictional force that structure produced of inserting antitheft steel cylinder, the anti-theft feature that the anti-theft nut of inserting antitheft steel ball in the groove is described no matter stability or endurance, reliability inequality gets a lot, so the structure of inserting antitheft steel ball in the nut groove is improved, imperative.
Summary of the invention: the utility model is the anti-theft nut that will design a kind of antitheft steel cylinder of respectively packing in two grooves of anti-theft nut.By to " a kind of anti-theft nut of the antitheft steel ball of in groove, only packing into " structure-improved, make the anti-theft feature of anti-theft nut more stable, more lasting, more reliable.The utility model be by: have the band groove nut (1) of protruding part, antitheft steel cylinder (2), soft endless loop (3), bolt (4) and a plurality of parts of assembling pad (6) to constitute, wherein:
The band groove nut (1) that the protruding part＜one 〉, is arranged: during horizontal positioned, having on the nut inner hole sidewall of protruding part, the antimere place of same cross section makes two and half bent moon thread form grooves (1-2), and groove is that an end is dark, the shallow (see figure 4) of the other end.
＜two 〉, antitheft steel cylinder (2): these parts are cylindrical shape parts made from steel; Be that the utility model plays one of critical piece of antitheft effect, its size and groove size are complementary.
＜three 〉, soft endless loop (3): these parts by soft material (example: nylon) make, profile in the form of a ring, its size with have the interior hole dimension of band groove nut (1) of protruding part to be complementary.
＜four 〉, bolt (4): these parts are metric system bolts, and it is the parts of use of combining with the band groove nut (1) that the protruding part is arranged.
＜five 〉, assembling pad (6): its plug is contained in the endoporus of band groove nut (1) of protruding part, at bolt (4) with before nut (1) combines, the parts that prevent antitheft steel cylinder (2) from groove, to come off away.The interior hole dimension of this part dimension and nut (1) is complementary.
The utility model that is made of above-mentioned parts is first by shown in Figure 3, and the band groove nut (1) that soft endless loop (3) is packed in the protruding part has on the end face of protruding part (1-1); Again by shown in Figure 4, antitheft steel cylinder (2) is packed in the groove (1-2), will assemble pad (6) then and fill in the endoporus of the band groove nut (1) that is incorporated with the protruding part, block antitheft steel cylinder (2) and avoid from groove (1-2), dropping out; Use assembled the band groove nut of protruding part is arranged the time, it is the hole of earlier bolt (4) being passed workpiece (5), (claim again: the band groove nut that the protruding part is arranged that has assembled) be screwedly mounted on bolt (4) and go up and tighten, at this moment bolt (4) ejects assembling pad (6) from the endoporus of nut (1) will to install the band groove nut (1) that the protruding part is arranged of soft endless loop (3), antitheft steel cylinder (2), assembling pad (6) more.
Advantage of the present utility model:
The advantage that not only has " a kind of anti-theft nut of the antitheft steel ball of in groove, only packing into " by above-mentioned the utility model that assembles; And has more stable, more lasting, a more reliable advantage of anti-theft feature than " a kind of anti-theft nut of the antitheft steel ball of in groove, only packing into ".
Description of drawings:
＜one 〉, Fig. 1: the utility model is the section of structure during user mode in engineering.
＜two 〉, Fig. 2: be to have the band groove nut (1) of protruding part to install soft endless loop (3), the antitheft steel cylinder of packing in groove (2) is filled in the assembling of packing into again and is filled up the sectional drawing of (6).
＜three 〉, Fig. 3: be to have the band groove nut (1) of protruding part to install soft endless loop (3) earlier, in groove, reinstall the sectional drawing of antitheft steel cylinder (2).
