Description
Technical field
The utility model relates to fastener areas, especially relates to a kind of one side and installs high strength anti-loose bolt system.
Background technique
Screw is for linking two objects, or utilize bolt that a certain assembly is fixed on the surface of another object tightly, the application area of bolt is very extensive, it can be found in general implements in daily life, among high-tech precision machinery, also can't do without it, common bolt is Spielpassung, uses easily generation to loosen through long-time, and when fixing at one side, when common bolt uses and inconvenience.
Model utility content
For solving the problems of the technologies described above, the utility model proposes a kind of one side and install high strength anti-loose bolt system, comprise screw rod, ring set, described ring set is placed on described screw rod; Described ring set comprises lock ring, overlaps with integrated distortion of described lock ring, and described distortion cover comprises supporting section and deformation section, and the hardness of described deformation section is less than the hardness of described lock ring, and the hardness of described lock ring is less than the hardness of described supporting section; Described screw rod comprises screw body and is positioned at the screw head of described screw body one end, and described ring set is pressed on described screw head, and described screw body surface alignment has circular groove.
The further preferred version that the utility model proposes, the inwall of described ring set is light face.
The further preferred version that the utility model proposes, described screw body is also provided with the pretightening force setting slot caved in, and described pretightening force setting slot is less than described ring set length to the distance of described screw head.
The one side that the utility model proposes installs high strength anti-loose bolt system following beneficial effect: ring set is placed on screw rod by this device, mother metal is butted on described lock ring, tension instrument is used to pull screw rod tail, pulling force is applied in screw rod radial direction, due to active force and reaction force, deformation section is stressed, produce deformation, forming projection is pressed on mother metal, due to the pulling force continued, mother metal is compressed, when pulling force increases, lock ring also deforms, because the mouth of tension instrument is provided with horn mouth, tension instrument is placed on lock ring gradually, lock ring deforms, be fixed on mother metal side, continue to pull, when pulling force arrives the value of pretightening force setting slot, screw body disconnects at pretightening force setting slot place, complete installation, this device is applicable to one side fixing bolt, easy to use, and good fixing effect, can not loosen.

Wherein, 1-screw body, 2-ring set, 3-lock ring, 4-is out of shape cover, 5-supporting section, 6-deformation section, 7-screw head, 8-circular groove, 9-pretightening force setting slot, 10-mother metal, 11-tension instrument.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Composition graphs 1-5, the utility model proposes a kind of one side and install high strength anti-loose bolt system, comprise screw rod, ring set 2, described ring set 2 is placed on described screw rod; Described ring set 2 comprise lock ring 3, with the integrated distortion cover 4 of described lock ring 3, described distortion cover 4 comprises supporting section 5 and deformation section 6, the hardness of described deformation section 6 is less than the hardness of described lock ring 3, and the hardness of described lock ring 3 is less than the hardness of described supporting section 5; Described screw rod comprises screw body 1 and is positioned at the screw head 7 of described screw body 1 one end, and described ring set 2 is pressed on described screw head 7, and described screw body 1 surface alignment has circular groove 8.
The further preferred version that the utility model proposes, the inwall of described ring set 2 is light face, when lock ring 3 receives the compression of tension instrument 11, lock ring 3 external diameter diminishes, the hardness of lock ring 3 is less than the hardness of screw body 1, and now, inwall is engaged in circular groove 8, lock ring 3 and screw body 1 interference fit, good fixing effect.
The further preferred version that the utility model proposes, described screw body 1 is also provided with the pretightening force setting slot 9 caved in, circular groove 8 on screw body 1 is divided into two sections by pretightening force setting slot 9, described pretightening force setting slot 9 is less than described ring set 2 length to the distance of described screw head 7, after the deformation section 6 becoming ring set 2 is out of shape, pretightening force setting slot 9 can expose by lock ring 3, the diameter that the diameter at pretightening force setting slot 9 place compares screw body 1 is little, when radial pull reaches certain value, pretightening force setting slot 9 place disconnects at first.
Working method of the present utility model is: as in Figure 3-5, this device coordinates tension instrument 11, ring set 2 is placed on screw rod, mother metal 10 is butted on described lock ring 3, uses the pulling claw of tension instrument 11 inside to hold screw rod tail, applies pulling force in screw rod radial direction, due to active force and reaction force, first, deformation section 6 produces deformation, forms projection and is pressed on mother metal 10; Due to the pulling force continued, mother metal 10 is compressed, when pulling force increases, lock ring 3 also deforms, and because the mouth of tension instrument 11 is provided with horn mouth, tension instrument 11 is placed on lock ring 3 gradually, lock ring 3 deforms, identical with the bucket wall shape of tension instrument 11, be fixed on mother metal 10 side, continue to pull, when pulling force arrives the value of pretightening force setting slot 9, screw body 1 disconnects at pretightening force setting slot 9 place, and tension instrument 11 is given up the throne, and completes installation.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
