Abstract
The utility model relates to a loose-proof anti-theft nut, which is easy to install. The nut comprises an upper cap nut 1, a lower cap nut 3 and a standard polygon prism jacketing 2 which combines the upper cap nut 1 and the lower cap nut 3 into integration. One end of the upper cap nut 3 is in shape of the standard polygon prisms, and the other end is in shape of cylindrical pipe identical with the lower cap nut 3. Both the exteriors of the upper cap nut 1 and the lower cap nut 3 closely fit the standard polygon prism jacketing 2. Both the upper cap nut 1 and the lower cap nut 3 have symmetrical zigzag form gear teeth engaging with each other. The utility model has the integral function of fastening, loosening and anti theft. The nuts can be locked in the reverse direction and screwed tightly again without specific tools. The utility model can be used as the special nuts for preventing steel towers from being stolen or the parts for mechanical connection.
Description
The utility model relates to mechanical parts, and a kind of specifically can lockingly unloading prevented stolen tightening nut.
As everyone knows, nut is as the basic part that connects various mechanical parts and device, the installation that is widely used in electric power network iron tower and guard against error railing be connected.Yet, the become flexible dismounting of plain nut acts on to the safety of various parts and has brought problem, often there is the dismounting tightening nut to cause the situation that the iron tower parts are stolen or railing damages in the reality, national wealth is incurred loss, and destroyed normal working state, serious may cause various accidents.For this reason, generally adopt anti-theft nut to address this problem in many engineerings.Though existing various anti-theft nut is of a great variety, all has different defectives and deficiency.ZL94206039.1 bolt anti-theft device for example is owing to the available dedicated instrument is dismantled and influenced antitheft reliability; ZL98232531.2 burglarproof lock jack panel, though solved antitheft reliability defective, the same with other anti-theft nuts, still exist installation back inconvenience to tighten up again, and complex structure, the deficiency that manufacture cost is high.In order to solve these defectives of existing anti-theft nut, 99234915.X patent has proposed iron tower burglarproof lock jack panel again, this new departure, traditional two caps and tight principle have been broken through, and adopted reverse locking principle, make its structure greatly simple, and can satisfy the requirement that operation power department regularly tightens up.But, because this burglarproof lock jack panel adopts in the tightening nut outside, wear the structure of circular steel bushing, and before installation, two parts simply are stained with to connect and are one, thereby in transportation process, easily make steel bushing and nut be separated into two parts, make troubles for taking of operator, because steel bushing is set on the outer first half of nut, gives fastening bringing inconvenience is installed simultaneously.
The purpose of this utility model provides the nut integral body that a kind of form structure is the many prismatics of standard, and internal structure is the fastening anti-theft nut of reverse locking, and is simple with implementation structure, easy for installation, the effect of reliable anti-loose anti-theft.
The technological scheme that realizes the utility model purpose is that the steel bushing shape of 99234915.X patent and the linkage structure between steel bushing and the nut are improved.This nut includes upper cap nut 1, following nut 3, and wherein the first half profile of upper cap nut 1 is the multi-edge column-shaped of standard type, the Lower Half profile is a cylinder tube shape; The profile of following nut 3 is a cylinder tube shape; Screw thread is respectively arranged in the upper and lower nut, and end face respectively has the saw shape teeth of symmetry; The Lower Half post ends of upper cap nut is meshed with following nut, and the multi-edge column-shaped overcoat 2 of outside drive fit standard type connects upper and lower nut as a whole.
The following nut 3 that the utility model is above-mentioned, its external diameter is identical with the cylindrical end external diameter of upper cap nut 1, and the internal thread of upper and lower nut is synchronous.
The multi-edge column-shaped overcoat 2 that the utility model is above-mentioned, its external diameter is identical with the first half polygon prism of upper cap nut 1 with shape.
The utility model becomes one it, thereby can conveniently install with fastening owing to adopt the overcoat and the drive fit linkage structure of nut up and down; Because the profile of upper and lower nut adopts the normal form nut,, need not special tool during use simultaneously so versatility is good; In addition because, the end face of upper and lower nut adopts the teeth meshing engagement structure, so can realize reverse locking.Have the advantage that integrates fastening, locking, antitheft, having changed existing iron tower installation is to increase the situation of adorning an anti-theft nut again in common tightening nut outside, realizes not only fastening but also antitheft purpose with a nut.And after loosening, can tighten up once more, can satisfy the requirement that operation power department regularly tightens up.
Further specify structure of the present utility model and use below in conjunction with accompanying drawing.
Fig. 1 is a cut-away view of the present utility model
Fig. 2 is a shape assumption diagram of the present utility model
Fig. 3 is user mode figure of the present utility model
Among Fig. 1, the first half of upper cap nut 1 is the six-sided nut of standard, and Lower Half is a cylindrical body, and end face is provided with saw shape teeth.Following nut 3 is a cylindrical body, and end face also is provided with saw shape teeth.Be provided with synchronous internal thread in the upper and lower nut, the teeth of upper and lower nut end face are meshed, and are with the six-sided nut cover 2 of standard in its outside.This nut sleeve 2 is that drive fit is installed with the cylindrical body of upper and lower nut.The outer warp of nut sleeve 2 is identical with the first half six-sided nut of upper cap nut with shape, makes its outer six-sided nut integral body that forms a standard, as shown in Figure 2.
Among Fig. 3, the 4th, tower material, framework, the 5th, bolt.During use, anti-theft nut is screwed on the bolt 5, with the clockwise fastening upper cap nut 1 of common wrench, nut screws to rely on end-side teeth to promote down and since up and down the nut end-side teeth mutually to the top effect, just can be locked immediately when reverse loosening upper cap nut, when reverse when unloading loose nut sleeve 2, overcoat only can rotate, but does not influence cap locking down, but safe antitheft.When tightening up if desired, only need again with the clockwise fastening upper cap nut 1 of common wrench, and reverse locked getting final product.
