Description
Technical Field
The utility model relates to the technical field of mechanical fastening equipment, in particular to a positive and negative nut fastening anti-loosening grabbing piece.
Background
Various fastened parts based on bolts and nuts are important parts which are indispensable in mechanical part connection and equipment fixing, and if the fastened objects are loosened, the equipment structures can be loosened, so that the devices cannot normally operate or damage the equipment structures.
But the locking between bolt and the nut between current bolt and the nut is not hard up, can use pin or glue usually, and the former is too troublesome, and the latter can't guarantee not to become flexible for a long time for when the great scene of operation environment vibrations of portion outside, thereby it is not hard up because vibrations just easily between nut and the bolt on its device, cause equipment operation trouble.
SUMMERY OF THE UTILITY MODEL
The utility model provides a positive and negative nut fastening anti-loosening grabbing piece, which aims to solve the technical problem that loosening is easy to generate between a common bolt and a nut.
In order to achieve the purpose, the utility model provides a positive and negative nut fastening anti-loosening grabbing piece which comprises a fastened piece, wherein a through hole is formed in the fastened piece, a hexagon bolt penetrating through the through hole is arranged on the fastened piece, an extending section is arranged at one end of the hexagon bolt, the anti-loosening grabbing piece is further arranged on the outer side of the hexagon bolt, the outer side of the anti-loosening grabbing piece is made into a grabbing piece which is formed by bending left and right, and the grabbing piece formed by bending is arranged in a manner of being capable of being bent towards two sides.
Furthermore, the bent grabbing pieces correspond to the outer side plane of the nut.
Furthermore, the outer side of the hexagon bolt is in threaded engagement with a first nut and a second nut.
Furthermore, the second nut is arranged on the outer side of the extension section, and the screwing direction of the meshing threads of the second nut and the extension section is opposite to that of the meshing threads of the first nut and the hexagon bolt.
Further, the anti-loosening grabbing piece is arranged between the first nut and the second nut.
Furthermore, the anti-loosening grabbing piece is made of 304 stainless steel materials and is not prone to rusting.
The positive and negative nut fastening anti-loosening grabbing piece has the following beneficial effects:
1. the device is provided with the extension section through hex bolts one end, and the second nut sets up in the extension section outside, and the interlock screw thread of second nut and extension section revolves to, and is revolved to on the contrary with the interlock screw thread of first nut and hex bolts, then can utilize two positive and negative rotations reversals of nut to fixed being linked into a whole, thereby after on the outside vibrations transmit equipment by the fastener, two nuts are because of linking as an organic whole, thereby improve by the locking effect of becoming flexible of fastener.
2. The device grabs the piece setting between first nut and second nut through locking, the piece is grabbed in the bending type and nut outside plane is corresponding, the piece is grabbed for can be to the crooked setting in both sides to the bending type to buckling type, then grab the piece and laminate to the crooked and first nut and second nut outside plane respectively of both sides as will locking adjacent bending type on grabbing the piece, thereby just can fix the relative position of first nut and second nut, when making order about first nut and second nut production not hard up displacement when outside vibrations, the piece will be grabbed in the bending type and the mutual restriction will be carried out to it, reach and further prevent by the not hard up effect of fastener.

FIG. 3 is a perspective view of the anti-loosening gripping tab of the present invention when bent to form a gripping tab that is not bent.
In FIGS. 1-3: 1-a fastened piece, 2-a hexagon bolt, 3-a first nut, 4-a second nut, 5-an anti-loose grabbing piece, 6-a grabbing piece formed by bending and 7-an extension section.
Detailed Description
Referring to fig. 1 to 3, an exploded view and a plan view of a positive and negative nut tightening anti-loosening gripping sheet are shown.
This embodiment provides a positive and negative nut fastening is locking grabs piece, include by fastener 1, seted up the through-hole on the fastener 1, by being provided with the hex bolts 2 that run through the through-hole on the fastener 1, 2 one ends of hex bolts are provided with extension 7, and the 2 outsides of hex bolts still are provided with locking piece 5 of grabbing, and locking piece 5 outside of grabbing is provided with bending type and grabs piece 6, and bending type grabs piece 6 and is can be to the crooked setting in both sides.
When concrete implementation, second nut 4 sets up in extension 7 outside, and the interlock screw thread of second nut 4 and extension 7 is revolved to, and is opposite with the interlock screw thread of first nut 3 and hex bolts 2, then can utilize one positive and negative two rotation reversals of nut, thereby after outside vibrations transmit equipment by fastener 1, just need shake earlier pine second nut 4 and just can shake pine first nut 3, utilize two nuts positive and negative to grab the piece and link as an organic wholely now, and then can not shaken the pine, improve by fastener 1's locking effect.
When concrete implementation, locking piece 5 of grabbing sets up between first nut 3 and second nut, and the bending type becomes to grab piece 6 and nut outside plane corresponding, then grab piece 6 and first nut 3 and the laminating of second nut 4 outside plane to both sides bending respectively as will locking adjacent bending type on grabbing piece 5, thereby just can connect integratively and fix the relative position of first nut 3 and second nut 4, make when outside vibrations order about first nut 3 and second nut 4 to produce not hard up displacement, bending type becomes to grab piece 5 and will restrict it, reach further to prevent by the not hard up effect of fastener 1.
The working principle of the positive and negative nut fastening anti-loose grabbing piece is as follows: firstly, an extension section 7 is arranged at one end of a hexagonal bolt 2, a second nut 4 is arranged at the outer side of the extension section 7, the rotation direction of the meshing threads of the second nut 4 and the extension section 7 is opposite to the rotation direction of the meshing threads of a first nut 3 and the hexagonal bolt 2, and the two rotation directions of the first nut and the second nut can be utilized, so that after external vibration is transmitted to a fastened piece 1 of equipment, the first nut 3 needs to be firstly shaken to loosen the second nut 4, the anti-loosening effect of the fastened piece 1 is improved, then, an anti-loosening grabbing piece 5 is arranged between the first nut 3 and the second nut, a grabbing piece 6 formed by bending corresponds to the outer side plane of the nut, the grabbing piece 6 formed by bending is arranged to be capable of being bent towards two sides, when the adjacent bending grabbing pieces 6 formed by bending on the anti-loosening grabbing piece 5 are respectively bent towards two sides to be attached to the outer side plane of the first nut 3 and the second nut 4, and the relative positions of the first nut 3 and the second nut 4 can be integrally fixed, when external vibration drives the first nut 3 and the second nut 4 to generate loosening displacement, the grabbing piece 5 formed by bending can limit the first nut and the second nut, and the effect of further preventing the loosening of the fastened piece 1 is achieved.
