Preferably, the screw rod further comprises a second locking piece, the second locking piece is of a circular plate structure, a second through restriction hole is formed in the center of the second locking piece, the second restriction hole is matched with the outer contour of the screw rod head, and a plurality of second notches are circumferentially formed in the outer edge of the second locking piece; the second notch is matched with the locking screw.
Preferably, the first notches are arranged in pairs and symmetrically distributed on two opposite sides of the first locking piece; the second notches are even in number and are uniformly distributed on the outer side of the second locking piece.
Preferably, a supporting sleeve is arranged between the first locking piece and the second locking piece, ratchets are respectively arranged at the top and the bottom of the supporting sleeve, and the inclination direction of the ratchets is opposite to the loosening direction of the nut.
Preferably, a locking gasket is arranged between the nut and the surface of the part; the locking screw is a shoulder screw.
The utility model has the beneficial effects that: the locking screw is fixed to the first locking piece through the first notch, rotation of the locking piece is avoided, and the first restraining hole and the nut form a restraining structure, so that anti-loosening fixation of the nut is achieved through the first locking piece. The second locking piece is far away from the same as the first locking piece, and the screw is fixed and restrained under the action of the locking screw and the second notch, so that the nut and the screw are locked together. The second locking piece can be fixed in a plurality of angles through the plurality of second notches. The supporting sleeve eliminates the drop between the first locking piece and the nut, thereby providing supporting force for the second locking piece and realizing complete fastening under the action of the locking screw.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
FIG. 1 is a prior art nut-screw securing structure;
FIG. 2 is a schematic diagram of an application mode of the present utility model;
FIG. 3 is a schematic top view of the present utility model;
fig. 4 is an exploded view of the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made more apparent and fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
According to the structure of fig. 2, 3 and 4, a nut-screw locking integrated structure for fixing a nut 1 and a screw 2 on the surface of a component comprises: the first locking piece 3 is in a circular plate structure, a first through restriction hole 4 is formed in the center of the first locking piece 3, the first restriction hole 4 is matched with the outer contour of the nut 1, and a plurality of first notches 5 are circumferentially formed in the outer edge of the first locking piece 3; a locking screw 6, said locking screw 6 being screwed to the surface of the component via said first notch 5.
Through the arrangement, the locking screw 6 fixes the first locking piece 3 through the first notch 5 to avoid rotation of the first locking piece, and the first restraining hole 4 and the nut 1 form a restraining structure, so that the locking fixation of the nut 1 is realized through the first locking piece 3.
In order to effectively loosen and fix the screw rod 2, the screw rod 2 adopts a square end structure, and therefore the screw rod further comprises a second locking piece 7, the second locking piece 7 is of a circular plate structure, a second through restriction hole 8 is formed in the center of the second locking piece 7, the second restriction hole 8 is matched with the outer contour of the head of the screw rod 2, and a plurality of second notches 9 are formed in the outer edge of the second locking piece 7 in a circumferential direction; the second recess 9 is adapted to the locking screw 6.
Through this setting, second locking piece 7 is kept away from the same with first locking piece 3, realizes carrying out fixed constraint to screw rod 2 under locking screw 6 and the effect of second breach 9 to reach the joint locking to nut 1 and screw rod 2.
The first notches 5 are arranged in pairs and symmetrically distributed on two opposite sides of the first locking piece 3; the second notches 9 are even in number and are uniformly distributed on the outer side of the second locking piece 7.
In this arrangement, the plurality of second notches 9 allow the second locking tab 7 to be secured at a plurality of angles.
A supporting sleeve 10 is arranged between the first locking piece 3 and the second locking piece 7, ratchets are respectively arranged at the top and the bottom of the supporting sleeve 10, and the inclination direction of the ratchets is opposite to the loosening direction of the nut 1.
In this arrangement the support sleeve 10 eliminates the fall between the first locking tab 3 and the nut 1, thereby providing a supporting force for the second locking tab 7 and achieving complete tightening under the influence of the locking screw 6.
A locking gasket 11 is arranged between the nut 1 and the surface of the part; the locking screw 6 is a shoulder screw.
In this arrangement, the anti-loose washer 11 prevents the nut 1 from being initially loosened and supported, while the shoulder locking screw 6 prevents the second locking piece 7 from deforming due to excessive pressure applied to the nut 1.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
