The nut can be detached through the adoption of a special tool for repeated use; and therefore, the cost is saved.
Description
Technical field
The present invention relates to a kind of fastening piece, specifically a kind of Demountable combined-type anti-loose anti-theft nut.
Background technique
Nut is a kind of widely used fastening piece that matches with bolt, as long as screw in the bolt matching with it, just clamped thing can be clamped, very easy to use, but in use, because artificially its dismounting being produced to unsafe factor, even have an accident sometimes.At present conventional axial locking anti-theft locking part generally can not be removed and reuse after installation, makes when changing difficulty large, causes damage simultaneously, improved cost.
Summary of the invention
In order to overcome existing axial locking theft-proof check nut, after installation, can not remove reusable deficiency, the invention provides a kind of Demountable combined-type anti-loose anti-theft nut, this nut adopts that special tool is dismountable to be reused, and has saved cost.
Technological scheme of the present invention is: a kind of Demountable combined-type anti-loose anti-theft nut, comprise outer-hexagonal circle, on described outer-hexagonal circle inwall, axially at least have a groove, the cross section of groove is arc, and groove top communicates with plane on outer-hexagonal circle, bottom is inner in outer-hexagonal circle, groove is built-in with knurling roler pin, in described outer-hexagonal circle endoporus, be equipped with screw thread inner ring, described screw thread inner ring inside is screw thread, its integral body is cylindrical body, and the top of cylinder is provided with boss, between described outer-hexagonal circle and screw thread inner ring, is equipped with elastomer block.
The difference of described outer-hexagonal circle internal diameter and the cylindrical body external diameter of screw thread inner ring is greater than 0.5mm, and the difference of the height of the cylinder height of screw thread inner ring and outer-hexagonal circle is greater than 1.5mm.
The radial depth of described groove is greater than 1mm, and its one end that is positioned at outer-hexagonal circle inside is hypotenuse.
Described knurling roler pin is metallic material, and its length is less than the axial length of groove, and the diameter of knurling roler pin is greater than 1mm, and its surperficial decorative pattern is a kind of of rhombus, vertical bar shaped, S shape.
Described elastomer block is nonmetallic material, and its thickness is greater than 0.5 ㎜, and length is greater than 5 ㎜, and width is greater than 2 ㎜.
The present invention has following beneficial effect: owing to taking such scheme, nut is carried out to split, on outer-hexagonal circle inner hole wall, process the axial curve bath of one group of radial equipartition, in curve bath, be provided with knurling roler pin, and be equipped with elastomer block between screw thread inner ring and outer-hexagonal circle, when installing and using and transport, can not scatter like this, very easy to use.When tightening, knurling roler pin is to the angle slippage of curve bath, and the larger friction of screwing force is just larger.When loose unloading nut, knurling roler pin slides to curve bath bosom automatically makes outer-hexagonal circle separated with screw thread inner ring, thereby plays the anti-anti-theft feature that unloads.

Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
By shown in Fig. 1 to Fig. 6, a kind of Demountable combined-type anti-loose anti-theft nut, comprise outer-hexagonal circle 5, the outside that 5 cross sections are enclosed at outer six degree angles is Hexagon, inner for circular, on described outer-hexagonal circle 5 inwalls, axially at least have a groove 3, groove 3 can be also two, three, circumferentially uniform along inwall.The cross section of groove 3 is arc, and the radius of curve bath 3 is 4～12mm, and its radial depth is greater than 1mm, the concrete degree of depth is determined according to screw thread specification size, groove 3 tops communicate with plane on outer-hexagonal circle 5, and bottom is in outer-hexagonal circle 5 inside, and its one end that is positioned at outer-hexagonal circle 5 inside is hypotenuse 6.Groove 3 is built-in with knurling roler pin 4, described knurling roler pin 4 is metallic material, its length is less than the axial length of groove 3, the diameter of knurling roler pin 4 is greater than 1mm, and its surperficial decorative pattern is a kind of of rhombus, vertical bar shaped, S shape, because the increase along with screwing force when tightening of surperficial decorative pattern increases, thereby reach, tighten requirement.In described outer-hexagonal circle 5 endoporus, be equipped with screw thread inner ring 2, described screw thread inner ring 2 inside are screw thread, and its integral body is cylindrical body, and the top of cylinder is provided with boss 1, and the external diameter of boss 1 should be greater than the groove 3 bottom land degree of depth, can prevent that like this knurling roler pin 4 from coming off.The difference of the cylindrical body external diameter of outer-hexagonal circle 5 internal diameters and screw thread inner ring 2 is greater than 0.5mm, and the difference of the height of the cylinder height of screw thread inner ring 2 and outer-hexagonal circle 5 is greater than 1.5mm.Between described outer-hexagonal circle 5 and screw thread inner ring 2, be equipped with elastomer block 7, elastomer block 7 is nonmetallic material, and its thickness is greater than 0.5mm, length is greater than 5mm, width is greater than 2mm, its effect be while transporting before installation by fixing between screw thread inner ring 2 and outer-hexagonal circle 5, knurling roler pin 4, avoid coming off.
During this nut combinations, first elastomer block 7 is sticked in outer-hexagonal circle 5, be placed in position, middle and lower part between two grooves 3, then screw thread inner ring 2 is inserted to 1/3 degree of depth of outer-hexagonal circle 5, knurling roler pin 4 inserts in groove 3, presses screw thread inner ring 2 until equal with outer-hexagonal circle 5.While using this nut, first determine that the member of installing is errorless, then have one end of boss 1 outside screw thread inner ring 2, the bolt that screw-in matches, forward is screwed into clamped parts, then adopts Wrench to continue to screw in, and knurling roler pin 4 slides to the angle of groove 3 voluntarily.When screwing force increases, the frictional force of knurling roler pin 4 also increases, thereby reach, tightens requirement.When anti-stubborn dismounting, knurling roler pin 4 slides onto the bosom of groove 3 voluntarily, and now, because having certain space between outer-hexagonal circle 5 and screw thread inner ring 2, outer-hexagonal circle 5 skids in the periphery of screw thread inner ring 2, has played the anti-anti-theft feature that unloads.As needs, remove and reuse, must adopt special-purpose removal tool.
