Embodiment
Be described in detail the technical solution of the utility model below by specific embodiment in order further to explain.
A kind of Novel bolt anti-loose structure of the present utility model as Figure 1-3, comprises bolt 1 and treats lock firmware 2.
Preferably, be formed with concentric little groove 211 in the groove 21, packing ring 3 is formed with and mates the step bulge loop 32 that is placed in the little groove 211, and little groove 211 is fastened togather with step bulge loop 32.
Preferably, sidewall in the little groove 211 is formed with draw-in groove 212, step bulge loop 32 corresponding draw-in grooves 212 are formed with the fixture block 321 that coupling is fastened togather, concrete structure can be, the groove that draw-in groove 212 is offered downwards for edge on the little groove 211, fixture block 321 is complementary with draw-in groove 212, can directly be snapped in by the upper notch of draw-in groove 212.
In order to strengthen the firm degree of little groove 211 and step bulge loop 32 phase buckles, preferably, the sidewalls in the little groove 211 are formed with a plurality of draw-in grooves 212, and step bulge loop 32 is formed with the fixture block 321 of respective numbers.
Preferably, flange 31 is formed with along the true dip direction of helical teeth 111 gradually away from the inclined-plane 311 of helical teeth 111 in a side of corresponding helical teeth 111, be that flange 31 is formed with for helical teeth 111 and takes advantage of a situation and slip over to screw the inclined-plane 311 of bolt 1, the tail end on the inclined-plane 311 after helical teeth 111 slips over is the buckle place of flange 31 and helical teeth 111.
