Abstract

The utility model provides a pentagonal roller anti-loose and anti-theft nut consists of a nut of which the outer appearance is a truncated cone contacted with a pentagonal roller and of which an inner hole is provided with two semi-arc wedge grooves, rollers and a temporary plug sleeve. A group of evenly distributed single direction semi-arc shaped wedge grooves are processed at the axial preset position of the inner hole of the nut, the rollers are positioned in the grooves, and the temporary plug sleeve is inserted into the inner hole of the nut to hold against the rollers to prevent the rollers not to drop off during the installation and the transportation. The five edges of the large diameter are screwed into the matched bolt as the supporting surface, the temporary plug sleeve is pushed out of the nut, and the rollers are remained in the semi-arc grooves with the both ends closed. When the loosening force is exerted, the rollers generate very large friction force to lock the loosening force; simultaneously the outer appearance of the nut adopts the cone-shaped table pentagon, the common spanner can not implement the loosening, and the double functions realize more reliable anti-loose and anti-theft function.

Description

Five limit roller anti-loose anti-theft nuts

Technical field

The utility model is that a kind of profile is that circular cone and pentagonal prism are tangent, and endoporus is opened the anti-loose anti-theft nut of wedge groove placement surface line trace roller.

Background technique

The utility model be at " loosing and theft preventing bolt auxiliary connection " (ZL03201292.6) nut of R have two defectives: (1) adopts special spanner to turn on, and anti-theft effect is unreliable; (2) profile angle and boss are interspersed, and special spanner overlaps the fashionable directivity that has, and installs and uses inconvenience.The utility model is a kind of nut with reliable anti-loose anti-theft function that designs at two above shortcomings.

Summary of the invention:

The utility model seals half arc wedge groove frustum, five limit nuts, surface marks roller and interim plug sleeve by band and forms.

Band of the present utility model seals half arc wedge groove nut, adopts pentagonal prism and round platform tangent on the profile, and bigger diameter end is a pentagon, and miner diameter end is circular, both rounding ofves; The axial desired location of nut inner hole has one group of uniform half arc wedge groove at interval, and radial view is half arc, and extruding sealing is adopted at two ends; Half arc wedge groove is put into roller, and roller is made by the metallic material of surface marks; Interim plug sleeve is made by the soft nonmetallic material of rubber-like, and there is one group of vertical boss the outer ring, and the boss race diameter is slightly larger than the nut path, and plug sleeve is not dropped.

The utility model when combination, earlier roller is put into the half arc wedge groove that seals of nut, fill in interim plug sleeve then, plug sleeve must block steel ball, and the position of plug sleeve will all cover in the wedge shape slotted eye, with prevent roller install and transportation process in the time shake.Plug sleeve will be lower than supporting surface 1-2 at nut inner hole and buckle screw thread, uses with the assembling of convenient supporting bolt.

When the utility model is implemented to install, interim plug sleeve can be squeezed along with the screw-in of supporting bolt releases nut inner hole, and roller is then sealed up for safekeeping in half arc wedge groove of nut, when implementing screwing force, roller does not produce resistance being subjected to be rolled to the groove depth place along curved line under the tangential screwing force promotion; When the enforcement pine was unloaded, roller can unload under the power effect pine and roll to the curve bath sharp corner, and along with the increase of roller magnitude of interference between bolts and nuts, the friction axial lock tense-lax of generation is unloaded power, thereby realizes reliable locking unloading functions.

Advantage of the present utility model: the skidding when (1) curve bath and surface marks roller have avoided roller to roll has increased the reliability of locking unloading functions; (2) the asymmetric polygonal of outside employing makes that must use special spanner, conventional spanner can't carry out pine when installation and pine are unloaded unloads; (3) seal during the moulding of nut wedge slot supporting surface and can stop the surface knurling roller in use to drop effectively.(4) this structure adopts dual locking unloading on profile and internal structure, and is scientific and reasonable for structure, installs simple and convenient.Product can be widely used in being fastenedly connected of field facilities such as electric transmission line, highway, bridge.

Embodiment

The utility model structure has nut (1), roller (2), interim plug sleeve (3) to combine as shown in Figure 1 and Figure 2.

The utility model nut (1) structure as shown in Figure 3, Figure 4, supporting surface end (big footpath) be a pentagon, miner diameter end is a circle.Process two groups of uniform half curve baths (4) on the position axis of distance nut (1) supporting surface 1-2 button, groove is half arc in the radial view of nut, and the degree of depth is slightly larger than roller (2) diameter, and the extruding sealing is adopted at the two ends of half arc port (4);

The utility model roller (2) structure as shown in Figure 7, roller (2) is made by metallic material, its diameter is slightly less than the degree of depth of half curve bath (4) of nut (1).

The periphery of plug sleeve of the present utility model (3) has one group of uniform vertical bead, and the circumscribed circle diameter of bead is slightly larger than nut (1) path, does not come off from nut inner hole to support plug sleeve (3).The outside diameter of plug sleeve (3) is slightly smaller than nut (1) path, but must guarantee that roller (2) does not drop in transportation and installation process.

During the utility model combination, earlier the roller of line trace (2) is put into the curve bath (4) of nut (1) endoporus, filled in interim plug sleeve (3) then, supporting surface one end stays 1-2 button screw thread convenient construction to install.

When implementing the utility model is installed, the big footpath of nut (1) one end is screwed in supporting bolt as supporting surface, screw-in along with screw thread, interim plug sleeve (3) can be pushed out nut (1) endoporus, roller (2) is then stayed the half arc wedge groove interior (4) of nut (1) and bolt formation by envelope, when the enforcement pine is unloaded power, roller (2) promotes the lower edge curved line and rolls to half arc wedge groove sharp corner and move tightening tangential force, along with and bolt thread and nut (1) arc cell wall (4) between the increase of magnitude of interference, produced increasing friction and stoped the pine of bolt to be unloaded; Nut (1) profile adopts cone platform pentagon simultaneously, and instrument commonly used can't clamp and loose removing nut (1), and both dual combination make the utility model realize anti-loose anti-theft function more reliably.

Nut of the present utility model (1) is and all can of bolt matching.
