Abstract
The utility model discloses a combined loosing and theft guarded nut, formed by a nut and an elastic washer. The nut is a section of top cone, which has a polygonal column divided by odd number at the large diameter end of the cone, each boarder of the polygonal column provided with a flange. Pressing face of the nut is provided with an internal ring trough. The combined loosing and theft guarded nut is screwed in a corresponding bolt to distort the elastic washer until the elastic washer is pressed into the internal ring trough of the nut as a plane. Two sharp hooks of the elastic washer are pressed into a tight connection part and the internal ring trough of the nut, respectively. The utility model, owing to the function of loosing and theft guard, and the removable ability under certain condition, could be especially widespread used in electric power, railway, and highway.
Description
Affiliated technical field
But the utility model relates to a kind of both anti-loose anti-thefts, again can dismountable under given conditions a kind of combined type anti-loose anti-theft nut.
Background technique
The utility model is to " integrated type the anti-loose anti-theft nut " (patent No.: shortcoming 912245638): complex structure, cost height, non-dismountable, and a kind of simple in structure, the cost low dismountable under given conditions " combined type anti-loose anti-theft nut " of design.
Summary of the invention
The purpose of this utility model is achieved in that the combined type anti-loose anti-theft nut is made up of a nut and an elastic washer.The nut profile is a truncated cone, and the bigger diameter end of cone is branch polygonal cylinders such as odd number, has a flange on each limit of polygonal cylinder.Because nut configuration design uniqueness when screwing or dismantle, must be used corresponding special tool, has realized antitheft effect.The nut seal face has an interior circular groove bigger slightly than elastic washer external diameter, that depth ratio elastic washer thickness is slightly little.Elastic washer is that the opening two ends have the opposite sharp hook of both direction respectively.During use, the combined type anti-loose anti-theft nut is screwed in respective bolt, and screw.Elastic washer is out of shape in the circular groove in nut, until reaching fastening connection requirement.The sharp hook of elastic washer is pressed into circular groove plane in fastening coupling and the nut respectively, has realized locking effect.External diameter became big when circular groove can prevent that elastic washer from being turned round in the nut, when external force is implemented dismounting, had increased dismounting torsion, anti-ly unloaded effect what to a certain degree play.In the time must dismantling under special circumstances,, can realize with the sizable power of special tool.
The utlity model has the dismountable again performance of anti-loose anti-theft, cost is low, and easy to use can work under vibration and difference variation state can be widely used in mechanical fields such as electric power, railway, bridge, highway.
Description of drawings
Below in conjunction with accompanying drawing and embodiment shown in the drawings, the utility model will be further described, but the content of model utility is not limited thereto.
Fig. 1 is the generalized section of facing of the utility model combined type anti-loose anti-theft nut.
Fig. 2 is the cross-sectional schematic of facing of the utility model anti-loose anti-theft nut.
Fig. 3 looks schematic representation for the left side of the utility model anti-loose anti-theft nut.

(1) is that nut (2) is nut circular groove (a 4) bolt for elastic washer (3) among the figure
Embodiment
The structure of this combined type anti-loose anti-theft nut is made up of special nut (1) and the elastic washer (2) that has interior circular groove of profile as shown in Figure 1.
Nut of the present utility model (1) is as Fig. 2, Fig. 3, shown in Figure 4, and profile is a truncated cone, and the bigger diameter end of cone is branch polygonal cylinders such as odd number, has a flange on each limit of polygonal cylinder, guarantees that special tool is non-slip when screwing.Because nut configuration design uniqueness has realized antitheft effect.Have one on nut (1) clamping plane than elastic washer external diameter is big slightly, the depth ratio elastic washer is slightly little interior circular groove (3).External diameter became big when interior circular groove (3) prevented that elastic washer from being turned round, and had increased dismounting torsion.
The utility model elastic washer (2) as shown in Figure 5, packing ring is that the opening two ends have the opposite single coil spring lock washer with tang ends of both direction respectively.
The combined type anti-loose anti-theft nut is screwed in respective bolt (4), make the middle compressive deformation of elastic washer (2) circular groove (3) in nut (1), until reaching fastening connection requirement.Two sharp hooks of elastic washer (2) be pressed into respectively fastening coupling and the interior circular groove of nut (1) (3) flat and, realized locking effect.In the time must dismantling under special circumstances,, can realize with the sizable power of special tool.
The utility model again can be detachable under given conditions owing to existing anti-loose anti-theft effect, therefore can be widely used on field or the not manageable fastened thing, guarantees the safety of fastened thing.
Claims (1)
