Abstract
An improved structure of an antitheft nut with a fixedly equipped soft annular ring belongs to the field of a mechanical product. An aim of the utility model is to provide the antitheft nut which has the following advantages: high water resistance, high vibration resistance, high galloping resistance and capability for keeping the antitheft function when one antitheft steel ball is lost. When the antitheft nut is horizontally placed, two semi-crescent-shaped grooves which respectively have a deep end and a shallow end are engraved on the symmetric parts of a same cross section at the inner walls of the nut with a projection part. A soft annular ring is fixedly equipped at an end face of the nut at a position where the projection part is provided. The two grooves are internally provided with a spring and an antitheft steel ball respectively. An assembling pad is filled in an inner hole of the nut. Finally the bolt passes through a hole of a workpiece. The assembled nut which is provided with the projection part and is provided with the grooves are screwed on the bolt. The bolt ejects the assembling pad from the inner hole of the nut. The antitheft nut with the fixedly equipped soft annular ring has the following advantages: high water resistance, high vibration resistance, high galloping resistance, and capability for keeping the antitheft function when one antitheft steel ball is lost.
Description
Technical field: the utility model belongs to the machinery product category, more definite a kind of structure-improved that installs the anti-theft nut of soft endless loop of saying so.
Background technique: field anti-dismounting facilities such as existing electric power tower and post and telecommunications iron tower adopt anti-theft nut more.At present in the anti-theft nut that adopts, by name: a kind of anti-theft nut that installs soft endless loop, though installed soft endless loop, its water-proof performance is good, anti-ly waves, anti-vibration is strong, so antitheft steel ball, spring all are difficult to corrosion, itself also is difficult for becoming flexible; But, also can only insert an antitheft steel ball in the groove owing to have only a groove on the nut inner hole sidewall.The shortcoming of this spline structure: when unique antitheft steel ball was deviate from from groove or damaged, the anti-theft feature of anti-theft nut just completely lost; Because the anti-theft nut groove of this structure can only come out with the lathe car, like this, the product machining clearance is not only loaded down with trivial details, and difficulty of processing is big, also easily produces reject, so there is the high shortcoming of product cost in addition.
Summary of the invention: the utility model is the structure-improved to " a kind of anti-theft nut that installs soft endless loop ".The utility model is that will to design a kind of not only water-proof performance good, anti-ly wave, the function of anti-vibration is strong, and product manufacture is simple, and is with low cost, especially when an antitheft steel ball drops out groove or damages, and the anti-theft nut that the anti-theft feature of product remains unchanged.The utility model be by: have the band groove nut (1) of protruding part, antitheft steel ball (2), soft endless loop (3), bolt (4), spring (6) and a plurality of parts of assembling pad (8) 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, and groove is that an end is dark, the shallow (see figure 4) of the other end.
＜two 〉, antitheft steel ball (2): these parts are steel spheroids, are that the utility model plays one of critical piece of antitheft effect, and 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 〉, spring (6): these parts are installed in the half bent moon thread form groove of band groove nut (1) of protruding part, the one end is connected with the end face of groove deep end, the other end links to each other with antitheft steel ball (2), and it is to block antitheft steel ball (2) to avoid the parts that come off away in groove.
＜six 〉, assembling pad (8): its is filled in the endoporus of the band groove nut (1) that is contained in the protruding part, combines the parts that the antitheft steel ball of preceding prevention (2) comes off away at bolt (4) with nut (1) from groove.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, spring (6) and antitheft steel ball (2) are packed in the groove, spring one end is connected with the end face of groove deep end, the other end is connected with steel ball (2), block steel ball and do not go out groove, to assemble pad (8) plug then and pack in the endoporus of the band groove nut (1) that the protruding part is arranged that assembled, and block antitheft steel ball (2) and avoid from groove, 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), the band groove nut (1) that the protruding part is arranged that will install soft endless loop (3), spring (6), antitheft steel ball (2), assembling pad (8) more is screwedly mounted on bolt (4) and goes up and tighten, and at this moment bolt (4) ejects assembling pad (8) from the endoporus of nut (1).
Advantage of the present utility model:
It is good not only to have water-proof performance by above-mentioned the utility model that assembles, and spring (6) and antitheft steel ball (2) are difficult for by corrosion, when being subjected to sharp pounding or waving, extremely difficult loosening; And manufacturing process is simple, and product cheap (cost reduce by 20%) especially drops out groove or loses or when damaging, the product anti-theft feature has the advantage that remains unchanged at an antitheft steel ball.
