Abstract
The utility model discloses a locking bolt connecting pair which comprises a bolt and a nut matched with the bolt; the nut is positioned at one side of a bolt body, and is provided with a flange part; and a locking gear surface is arranged at one side, which is close to the bolt body of the flange part. During the screwing process of a bolt assembly provided by the utility model, the nut extrudes the bolt threadedly so as to generate great counter-acting force and friction force, so that the bolt is prevented from falling back; meanwhile, the bolt with a gear surface of the flange part and the gear surface of the nut generate friction force to the contact point, the friction force is intensified, and the locking effect is achieved; and the locking durability is improved to great extent.
Description
Technical field
The utility model relates to the mechanical fitting field, particularly is applied to heavy truck, petroleum machinery, and automotive industry, traffic track, engineering machinery, the chek bolt auxiliary connection of equipment overall structure stability and Security is guaranteed in the fields such as aviation industry.
Background technique
It is a kind of very common mode that is fastenedly connected of mechanical field that bolt connects, usually cooperate fastening by screw bolt and nut, but general screw bolt and nut cooperates, of long duration can occur loosening, especially vibrations occur mechanically in the transmission of lathe band, chain transmission etc., it is loosening that bolt connects easier generation, if overhaul untimely, can produce various negative consequences, cause potential safety hazard.In order to prevent becoming flexible, usually adopt the modes that increase pad more, install pad additional and can alleviate bolt looseness to a certain extent, but effect is unsatisfactory.
The model utility content
Vibrations are occuring mechanically in what main purpose of the present utility model was to overcome prior art easily, if overhaul untimelyly, can produce various negative consequences, cause the shortcoming of potential safety hazard, propose a kind of chek bolt auxiliary connection.
The utility model adopts following technological scheme:
A kind of chek bolt auxiliary connection, comprise bolt and the nut that cooperates with it, described bolt comprises nut and key, it is characterized in that: this nut is positioned at edge of key and has extended to form flange part along vertical key direction, and this flange part is provided with the locking flank of tooth near described key one side.
Further, described nut one end margin has extended to form flange part along vertical key direction, and this flange part one side also is provided with the locking flank of tooth.
Further, described locking teeth face comprises some circumferential locking teeths, each locking teeth comprises the plane of inclination that is formed at the flange part bottom surface and the step surface that links to each other with this plane of inclination, and described plane of inclination comprises the dual-side that interval vertically arranges, and described step surface links to each other with a side wherein.
Further, described plane of inclination dual-side is arc-shaped side edges.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect:
The utility model is by arranging respectively flange part at screw bolt and nut one end, and in flange part one side the locking flank of tooth is set, and the locking teeth of this locking flank of tooth has certain inclination.In actual applications, can suitably adjust effective diameter of thread and the large footpath of screw bolt and nut, so that bolt assembly is in the process of tightening, nut produces powerful reaction force and frictional force to the bolt thread extruding, thereby stops bolt to retreat, simultaneously, because the flank of tooth butt contact of the screw bolt and nut of the flange part band flank of tooth produces frictional force simultaneously, strengthen frictional force, reached anti-loosing effect, improved to a great extent locking endurance.

Embodiment
Below the utility model will be further described by embodiment.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of chek bolt auxiliary connection, comprise bolt and the nut that cooperates with it, bolt comprises nut 2 and key 1, this nut 2 is positioned at 1 one edges of key and has extended to form flange part 3 along vertical key direction, and this flange part 3 is provided with the locking flank of tooth 4 near key 1 one sides.Same, nut one end margin also is formed with flange part 3 along vertical key direction extension, and these flange part 3 one sides also are provided with the locking flank of tooth 4.With reference to Fig. 5, the locking flank of tooth 4 comprises some circumferential locking teeths, each locking teeth comprises the plane of inclination 11 that is formed at flange part 3 bottom surfaces and the step surface 12 that links to each other with this plane of inclination 11, plane of inclination 11 comprises two arc-shaped side edges 13 that interval vertically arranges, and step surface 12 links to each other with a side wherein.
The utility model is by arranging respectively flange part at screw bolt and nut one end, and in flange part one side the locking flank of tooth is set, and the locking teeth of this locking flank of tooth has certain inclination.In actual applications, can suitably adjust effective diameter of thread and the large footpath of screw bolt and nut, so that bolt assembly is in the process of tightening, nut produces powerful reaction force and frictional force to the bolt thread extruding, thereby stops bolt to retreat, simultaneously, because the flank of tooth butt contact of the screw bolt and nut of the flange part band flank of tooth produces frictional force simultaneously, strengthen frictional force, reached anti-loosing effect, improved to a great extent locking endurance.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
