Receive the fixing hole of fix bar.
Preferably, the nut is in cylinder design, the mounting cap is in cylinder design, the mounting cap it is transversal
Face is identical with the area of the cross section of nut.
Preferably, the rotary shaft is symmetrically arranged at the both sides of driver flutes with fixing hole, the driver flutes are a word
Cutter groove or cross cutter groove.
Preferably, the both ends of the spring is are fixedly connected with, the length of the spring is less than the depth of mounting hole, described
The outer end of fix bar is less than the thickness of nut for the length of circular-arc-shaped design and fix bar, and the portion integral formula of the nut is provided with
The a plurality of radially-arranged anti-skidding convex tendon along nut.
The beneficial effects of the utility model：The utility model is fixed with spiral shell by the center of the downside in nut
Bar, driver flutes are offered in the center of the upside of nut, rotated and be provided with by rotary shaft at the edge on the top of nut
Mounting cap, vertically arranged mounting hole is offered in the bottom of mounting cap, slided in mounting hole and be provided with fix bar, in fix bar
The inner and the bottom of mounting hole between be connected with spring, offered on the top of nut be available for accommodate fix bar fixing hole,
The a plurality of radially-arranged anti-skidding convex tendon along nut is provided with the portion integral formula of nut, when can be with when using the bolt
It is stuck in using the cutter head of screwdriver in driver flutes and bolt is tightened, cap can be rotatablely installed after bolt is tightened, is pacified
The fix bar of cap bottom is filled by inside meeting Hui Na after the extruding force at the edge of nut to mounting hole, now spring is compressed,
It is rotated further mounting cap and make it that fix bar is relative with fixing hole, now fix bar extend into fixation due to the elastic force effect of spring
In hole so that mounting cap is fixed on the surface of nut and then so that driver flutes are completely covered mounting cap, can prevent
Screwdriver is dismantled to bolt, and due to being provided with anti-skidding convex tendon in the bottom of nut, when bolt is fastened, anti-skidding convex tendon can be embedding
Enter in object and then prevent bolt from producing loosening due to vibrations, compared with prior art, can effectively prevent bolt by other people
Arbitrarily dismounting, effectively prevents bolt looseness, improves the safety and reliability that bolt uses, simple in construction, easy to use, just
In popularization and application.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of new anti-demounting bolt of the utility model.
In figure：The anti-skidding convex tendon of 1- nuts, 11-, 2- screw rods, 3- driver flutes, 4- mounting caps, 5- mounting holes, 6- fix bars,
7- springs, 8- fixing holes, 9- power transmission shafts.
【Embodiment】
Refering to Fig. 1, a kind of new anti-demounting bolt of the utility model, including nut 1, screw rod 2, driver flutes 3, mounting cap
