Description
Technical field
The utility model relates to a kind of fastening piece, especially relates to a kind of anti-assembling nut that is used for field facilities such as electric power, highway, railway and park sports equipment.
Background technique
The fastening structure of existing technology much adopts the cooperation of bolt and nut to accomplish, and promptly nut is fixed by a direction screw-in bolt, screws out to another way and can unclamp.When the nut of existing technology is used for the structural member on the field facilities such as fastening electric power, highway, railway and park sports equipment, is dismantled privately by other people easily, thereby facility is incurred loss, and, also possibly cause security incident in the occasion of some special applications.Open day is on November 25th, 2009; Publication number is that the patent document of CN201351666Y discloses a kind of antitheft lock nut; On the inwall of screw, be provided with groove, be provided with neck bush in the screw, neck bush and screw inwall are fitted; In said groove, be inserted with roller, roller surface is provided with netted decorative pattern or some briar tooths.Though this structure can play certain anti-effect of unloading, and has two large problems during actual the use, the one, the recess space on the screw inwall is bigger, and during the nut counter-rotating, roller rests in the groove sometimes rather than snaps in screw thread, therefore can't play the anti-effect of unloading; The 2nd, because roller and nut are separation structures, it is spacing with roller therefore need lining to be set in nut, so not only increased the cost of anti-assembling nut, and the assembling work amount of roller and lining is very big, has influenced manufacturing efficiency.
The model utility content
The purpose of the utility model is for the roller that solves in the existing technology anti-assembling nut rests on the problem that the anti-assembling nut cost is high, manufacturing efficiency is low that can't play anti-effect of unloading and existing technology in the groove sometimes, and a kind of anti-anti-assembling nut effective, that cost is low that unloads is provided.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: a kind of anti-assembling nut, and the internal thread place of said nut is provided with locking trough, is provided with the stopping roller in the locking trough; The degree of depth of said locking trough reduces along the direction of screwing of nut gradually; Its cross section is wedge shape, and the groove depth of the bigger side of the locking trough degree of depth is greater than the diameter of stopping roller, and the two end part of locking trough are all at the nut inner sealing; Also be provided with the elastic top selection structure in the locking trough; The elastic top selection structure is arranged on the bigger side of the locking trough degree of depth, and an end of elastic top selection structure and the cell wall of locking trough are fixed, and the other end is connected with the outer side surface of stopping roller.When nut was just changeing the screw-in bolt, the stopping roller in the locking trough was through extruding elastic top selection structure, and to the darker side shifting of locking trough, the stopping roller can not hinder the screw-in of nut; And when nut counter-rotating was withdrawed from, the stopping roller to the more shallow side shifting of locking trough, and in the middle of the screw thread of final insert nut and bolt, can't reverse nut and withdraws under the elastic force effect of elastic top selection structure, prevented unloading effect thereby reach.Because the elastic top selection structure exists the elastic force of the stopping roller being pushed to wedge shape stopping slot wedge point one side all the time; Therefore the recess space that has solved on the anti-assembling nut inwall of existing technology is bigger; During the nut counter-rotating; Roller rests in the groove easily rather than snaps in screw thread, therefore can't play anti-problem of unloading effect.In addition, an end of elastic top selection structure and the cell wall of locking trough are fixed, and the other end is connected fixing with the outer side surface of stopping roller; Like this, the stopping roller just constitutes one with nut, can save bush structure; Reduce cost and assembling work amount, improved manufacturing efficiency.
As preferably, the elastic top selection structure is a sponge strip, and the length of sponge strip is smaller or equal to the length of stopping roller.One end of sponge strip can be adhesively fixed with the cell wall of locking trough, and the outer side surface of the other end and stopping roller is adhesively fixed.
As the another possibility, the elastic top selection structure is a spring, and said spring is one or two, and the length direction of stopping roller is on the width direction of locking trough.The cell wall of spring and locking trough can when the nut nominal diameter is bigger, when stopping roller length is longer, can adopt the structural type of two springs through connecting and fixing with the stopping roller through being adhesively fixed; For less anti-assembling nut, a spring can meet the demands.
As preferably, locking trough is 1 to 3, and locking trough is arranged on the end of nut away from screw terminal, and the length of locking trough is 50% to 70% of nut total thickness.Locking trough is arranged on the nut away from an end of screw terminal, is to consider when nut has just screwed in bolt, and the first few screw thread on the nut is complete, thereby makes things convenient for the screw-in of nut.
As preferably, the surface of stopping roller is provided with straight burr or reticulate pattern or granular protruding structure.The straight burr of stopping roller surface setting or reticulate pattern or granular structure help the stopping roller to embed screw thread, avoid skidding between stopping roller and the screw thread, influence the stopping effect.
As preferably, the outer side surface of nut has the structure of square or regular pentagon or regular hexagon or octagon.Its outer side surface of nut commonly used adopts square, regular pentagon, regular hexagon or octagon structure more; Wherein the regular pentagon structure can not be turned on common spanner; Itself just have certain anti-unloading functions, the outer side surface of nut also can adopt other structure.
As preferably, one section outer side surface of nut is a round column structure, is arranged with sliding sleeve on the round column structure, and the external diameter of sliding sleeve is greater than the inscribed circle diameter of nut outer side surface and less than the circumscribed circle diameter of nut outer side surface, the length of sliding sleeve is 40% to 60% of nut total thickness.Because the moment that needs when the moment that needs during nut screwing clamping is unclamped less than nut usually; Therefore half of nut outer side surface is arranged to sliding motion structure; Effective surface of contact of spanner and nut reduces like this; Can increase the difficulty of unclamping nut, and during nut screwing clamping, such area of contact can be satisfied the demand.
As preferably, the internal thread place of described nut is provided with and prevents that elastic top selection structure and stopping roller break away from the lining of locking trough.Though the elastic top selection structure of the utility model is connected with locking trough; And the stopping roller all is connected with the elastic top selection structure, but because elastic top selection structure and stopping roller are less relatively, possibly occur coming off in the time of being connected with between them; Therefore in practicality, break away from locking trough in order to stop elastic top selection structure and stopping roller; Also can adopt lining that locking trough is covered, the lining has here played the second heavily effect of protection, thereby has guaranteed the quality of each nut.
The beneficial effect of the utility model is: it has solved the problem that the anti-assembling nut cost is high, manufacturing efficiency is low that roller in the anti-assembling nut of existing technology rests in the groove sometimes, can't play anti-effect of unloading and existing technology effectively; The anti-assembling nut of the utility model is anti-unload effective, cost is low and manufacturing efficiency is high, has very high use value.
