Specific embodiment

With reference to the accompanying drawings and detailed description this utility model is described in further detail.

Herein and once reinforce in embodiment for hex nut, but this can not limit the use of our disconnection proof clamping hook devices Scope, no matter which kind of shape is the nut profile for needing fastening be, can be reinforced by our product.

Embodiment 1

As shown in figure 1, a kind of disconnection proof clamping hook device 10, is used cooperatively with hex nut, including fastening face 1, fastening face is With certain thickness plane, fastening face is in subtriangular, one of 1.1 while to fix, and fixes while with three, Angle between two neighboring side is 120 °, and the length on each side is identical with the monolateral length of hex nut or is slightly larger than hex nut Monolateral length, so fixing side 1.1 just can be by including hex nut fixing.

There is installing hole formed therein 1.2 in fastening face 1, fixed by securing member.

Position limiting structure is connected with fastening face, position limiting structure 2 includes the first gag lever post 2.1 and is arranged on the first gag lever post Second gag lever post 2.2 of end.

First gag lever post 2.1 is fixedly connected on fixing 1.1 end of side and, the length of first gag lever post 2.1 vertical with fastening face Degree is adapted with hex nut thickness to be tightened；Second gag lever post 2.2 is parallel with fastening face place plane, the second gag lever post 2.2 extend to hex nut direction to be tightened.

By the obstruction of the second gag lever post, hex nut direction movement axially along a screw is limited, and then limits hex nut Rotate along screw flight, fix side 1.1 and hex nut rotation can be further limited by including hex nut fixing just.

By above-mentioned improvement, can not only be limited in hex nut in-plane, while can be in hex nut axle Limited to direction, reached good slip-off preventing effect.

Embodiment 2

Basic structure is identical with disconnection proof clamping hook device in embodiment 1, is only the rectangular configuration that is shaped as of fastening face, fastening face On have two installing holes, more firm fixes the disconnection proof clamping hook device.

Embodiment 3

A kind of disconnection proof clamping hook device 10 that can fix three hex nuts simultaneously, including the fastening face 1 of strip, along fastening 1 long side direction of face is provided with three position limiting structures 2, and position limiting structure corresponds to the position of three hex nuts to be tightened, spacing knot respectively Structure 2 includes the first gag lever post 2.1 and is arranged on the second gag lever post 2.2 of the first gag lever post end, the first gag lever post 2.1 with it is tight Gu face 1 is vertical and parallel with fastening face thickness direction, the length of the first gag lever post 2.1 is mutually fitted with hex nut thickness to be tightened Match somebody with somebody；Second gag lever post 2.2 is parallel with fastening face 1, and the second gag lever post 2.2 extends to hex nut direction to be tightened.

During use, three hex nuts are tightened into fixation first, the fastening face of disconnection proof clamping hook device is arranged on into six then On the end face that angle nut is fixed, the second gag lever post pushes down the edge of three hex nuts, then will by rivet or bolt etc. Fastening face is fixed with end face is installed, and prevents hex nut from loosening, by three hex nuts by disconnection proof clamping hook device efficient association, Prevent single hex nut from loosening.

Embodiment 4

A kind of disconnection proof clamping hook device, can reinforce multiple hex nuts simultaneously, its fastening face 1 be tetragon framework, framework There is the void region 1.3 for allowing screw rod and hex nut to pass through centre, and fastening face 1 is provided with multiple position limiting structures 2, position limiting structure 2 both sides for being disposed on fastening face 1 are simultaneously corresponding with hex nut position to be tightened, make the power that fastening face is subject to more equal Even, fixation is more firm.
