Accompanying drawing explanation
Fig. 1 is the schematic diagram of an embodiment of threaded anti-loosing structure in the utility model, is also the structural representation of an embodiment of checknut assembly in the utility model simultaneously;
Fig. 2 is the sectional view of Fig. 1.
The name that in figure, each reference character is corresponding is called: 10 anti-loosen screw nut components, 11 fixed covers, 111 inward flanges, 12 Spiralock nuts, 13 spring washers, 21 first connected pieces, 22 second connected pieces, 30 bolt penetration hole, 40 flange face bolts, 41 locking teeths.
Embodiment
In the utility model, an embodiment of threaded anti-loosing structure is as shown in Fig. 1 ~ Fig. 2, a kind of for by two connected piece linkage structures be fixed with bolts, comprise and correspondingly respectively on the first connected piece 21, second connected piece 22 and anti-loosen screw nut component 10, first connected piece 21 and the second connected piece 22 be provided with the bolt penetration hole 30 of passing for corresponding flange face bolt 40.
Anti-loosen screw nut component 10 comprises fixed cover 11, Spiralock nuts 12, spring washer 13 and flange face bolt 40 as lock nut.Wherein fixed cover 11 adopts steel to make, it is hollow hexagonal prism structure structure, hollow parts is the hexagon receiving cavity corresponding with the shape of hexagon Spiralock nuts 12, it is the open end entered for Spiralock nuts 12 for the fixed end fixing with the first connected piece 21, form nut entrance, form the opening passed for flange face bolt 40 simultaneously.Fixed cover 11 away from one end of fixed end be provided with for Spiralock nuts 12 vertically block coordinate and the inward flange 111 stoping Spiralock nuts 12 to be deviate from, described inward flange 111 is greater than Spiralock nuts 12 internal diameter in the corresponding end formation of fixed cover 11 and is less than the through hole of Spiralock nuts 12 external diameter, and the excessive portion for flange face bolt 40 passes.The axial length of fixed cover 11 than the thickness of the Spiralock nuts 12 of prepackage and the thickness sum of spring washer 13 bigger, when avoiding installing, Spiralock nuts 12 and spring washer 13 are deviate from from the fixed end of fixed cover 11, conveniently install.The flanged surface of flange face bolt 40 is provided with locking teeth 41, can push up and being pressed on connected piece, being engaged with the fastening surface of connected piece, playing certain locking effect when screwing.
During use, first Spiralock nuts 12 is put into fixed cover 11 from the fixed end of fixed cover 11, then spring washer 13 is also put into fixed cover 11, the fixed cover 11 loading Spiralock nuts 12 and spring washer 13 is welded on the first link, re-use flange face bolt 40 through the second connected piece 22 and the first connected piece 21, and enter in fixed cover 11 and screw with Spiralock nuts 12.After flange face bolt 40 reaches Tightening moment, the fastening structure of its flanged surface is engaged with fastened, reaches a heavy anti-loosing effect; Now spring washer 13 is also compacted, between flange face bolt 40 and Spiralock nuts 12, produce expanding force, reaches the second heavy anti-loosing effect; Spiralock nuts 12 plays triple anti-loosing effect.Above-mentioned threaded anti-loosing structure achieves multiple locking, and anti-loosing effect is obvious, and later period maintenance is very convenient, as long as turn flange face bolt 40 can realize dismounting.
Anti-loosen screw nut component 10 in the utility model in an embodiment of anti-loosen screw nut component and the embodiment of above-mentioned threaded anti-loosing structure, concrete structure repeats no more herein.
In the above-described embodiments, fixed cover 11 is hollow hexagonal prism structure structure, and the through hole that fixed cover 11 is provided with Stop structure away from one end of fixed end and passes for bolt, and lock nut adopts is Spiralock nuts 12, and bolt is flange face bolt 40.In other embodiments of the present utility model, fixed cover 11 also can adopt other shapes, such as inside is hexagon, the outside structure for circle, fixed cover 11 also can be arranged to seal structure or wide-open structure away from one end of fixed end, when being arranged to wide-open structure, lock nut can be inserted from this section.And lock nut also can replace to the nut that other have locking functions, such as self-locking nut, nylon insert nut etc.; Bolt also can adopt common hex head bolt, or adopts screw, adopts during screw and preferably adopts flanged surface to be provided with the flanged surface screw of locking teeth 41.In addition, in other embodiments, nut entrance on fixed cover 11 also can be arranged on the side direction of fixed cover 11, and fixed cover 11 also can adopt the mode beyond welding to be fixed on connected piece, such as otic placode is set on the fixed end of fixed cover 11, adopts threaded fastener, rivet etc. to be fixed on connected piece.
