Abstract
An antitheft anti-loosening nut comprises a cylindrical nut body, the upper end of the nut body is provided with a cut through the nut to internal thread, the middle of the cut is downwardly recessed, the circumference of the nut body is provided with a groove, a clamping ring matching with the groove is arranged in the groove, the clamping ring is higher that the circumference of the nut body, and the nut body is provided with three longitudinal grooves symmetrically. As a common nut is modified, the antitheft anti-loosening nut is simple in structure, convenient in processing and fine in antitheft and anti-loosening effects, and is especially suitable for high-tension aerial line towers, metal frameworks of high-rise buildings, metal frameworks of bridges, railways and the like.
Description
Technical field
The utility model belongs to the machanical fastener technical field, especially has the fastening piece of antitheft merit, locking energy.
Background technique
Fastening piece is to be fastenedly connected to use and use class mechanical parts very widely.On various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous.Existing hardware mostly adopts plain bolt to be connected fastening mode with nut.It is fastening to do connection with the plain bolt nut, and the Structural Hardware product for will often tearing the fortune assembling open provides convenience in dismounting.But, also has quite a few Structural Hardware building, as the high-tension overhead line iron tower, the metal frame of high-story house, the bridge metal frame, railway etc., after the assembling, generally no longer dismounting, this class is once assembled the metallic structures of permanent use, owing to adopt the plain bolt nut that does not have anti-loosening measure to connect fastening, through wind rain beautiful jade, year in and year out, the corrosion of metal surface or the reason that in wind and rain, shakes naturally, nut loosening it is often arranged, if in time do not find maintenance, this metalloid structure member distortion occurs because of connecting insecure meeting. or cause bolt and nut to come off. and building taking place fall major accidents such as field, causes immeasurable loss for national economic construction and the people's lives and property safety.In addition, make of plain bolt and nut and to be connected fastening piece, general purpose tool is promptly removable, goes up the obstinate lawless person of only a few for society and is engaged in the theft destructive activity with opportunity.For preventing that by the dismounting of non-original idea increasing people carries out the research of some anti-theft fastening pieces.Though the nut that has has anti-theft feature, does not have locking functions, the antitheft lock nut complex structure that has, processing is inconvenient.
The model utility content
It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, and have locking and nut anti-theft feature.
For achieving the above object, the utility model has adopted following technological scheme to be: a kind of antitheft lock nut, comprise nut body, and it is characterized in that: nut body is cylindrical, and the nut body upper end portion is provided with otch, and otch is penetrated into the internal thread of nut.The otch middle part forms depression downwards.
Otch is usually located at the left and right sides of nut body, and distance is 1mm-2mm from the nut body upper-end surface.
As preferably, on the circumference of nut body, offer groove, be provided with suitable snap ring in the groove, snap ring exceeds the circumferential surface of nut body.Usually snap ring is 2mm-3mm from nut body upper-end surface distance.
As preferably, the nut body symmetry offers three pods.Article three, acting as in processing the time of the present utility model of pod, the frock of equipment can be grabbed clamping, with convenient processing, in addition, but the design specialized instrument be fastened on three pods, with tightening of convenient first nut.
Usually in the man-hour that adds of finishing otch, beat to the nut body upper end portion with instrument, will form depression downwards at the otch middle part like this, reduce the internal thread pitch of nut upper end, as preferably, method such as can heat-treat, increase its stress, make when reducing the internal thread pitch of nut upper end, when screwing bolt, sting tightly effective.Certainly,, can after tightening, beat to the nut body upper end portion, also can reach certain effect with instrument to not forming the nut of depression downwards at the otch middle part.
During use, nut of the present utility model with on the special tool precession bolt, and is tightened, the otch middle part forms depression downwards, reduces the internal thread pitch of nut upper end, pushes the outside thread of corresponding bolt.Like this, the outside thread interlock that the internal thread of nut upper end and bolt cooperate is very tight, stops nut loosening, just is difficult to after screwing withdraw from, and can not become flexible, thereby help nut to play the anti-loose anti-theft effect.The circumference of nut body is provided with snap ring, adopts instrument commonly used such as pipe tongs can not nut be back-outed like this, has increased theftproof performance.
The beneficial effects of the utility model are: owing to improve on plain nut, simple in structure, easy to process, antitheft, anti-loosing effect is good, is specially adapted to the occasion such as metal frame, bridge metal frame, railway of high-tension overhead line iron tower, high-story house.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is that the utility model embodiment's master looks schematic representation.
Among the figure: 1, nut body 2, otch 3, groove 4, snap ring 5, pod 6, depression
Embodiment
Among Fig. 1, a kind of antitheft lock nut, nut body 1, nut body 1 is cylindrical, nut body 1 upper end portion is provided with otch 2, and otch 2 is penetrated into the internal thread of nut, and otch 2 symmetries are positioned at the left and right sides of nut body 1, otch 2 middle parts form depression 6 downwards, and otch 2 is 1mm from nut body 1 upper-end surface distance.On the circumference at 2mm-place, nut body upper-end surface, offer groove 3, be provided with suitable snap ring 4 in the groove 3, snap ring 4 exceeds the circumferential surface of nut body 1.Nut body 1 symmetry offers acting as in processing the time of the present utility model of 5, three pods 5 of three pods, and the frock of equipment can be grabbed clamping, with convenient processing, in addition, but the design specialized instrument be fastened on three pods 5, with tightening of convenient first nut.
During use, nut of the present utility model is used on the special tool precession bolt, and tightened,, reduce the internal thread pitch of nut upper end, push the outside thread of corresponding bolt because otch 2 middle parts form depression 6 downwards.Like this, the outside thread interlock that the internal thread of nut upper end and bolt cooperate is very tight, stops nut loosening, just is difficult to after screwing withdraw from, and can not become flexible, thereby help nut to play the anti-loose anti-theft effect.The circumference of nut body 1 is provided with snap ring 4, adopts instrument commonly used such as pipe tongs can not nut be back-outed like this, has increased theftproof performance.
