Abstract
The utility model provides an anti-theft lock bolt pair of novel structure. The lock bolt pair is a sink type fastening bolt joint on one end of which a special-shaped multi-edged screw nut is arranged while the space between the screw nut and a counterbore is the clearance for the insertion of a wrench. The counterbore in the art proposal is the sheath of the screw nut and can not be fastened or released without a special wrench, so as to protect and to prevent theft.
Description
Technical field
The utility model relates to detachable clamping bolt technology, in particular realize the clamping bolt technology of antitheft dismounting.
Background technique
In order to realize the technical purpose of the antitheft dismounting of clamping bolt, prior art provides diversified structure type, as designs a kind of bolt of lug, or in nut bottom surface design hangnail or the like structure, to stop illegal dismounting.Their technical characterstic is each has something to recommend him, and technique effect also has nothing in common with each other.
The model utility content
Goal of the invention of the present utility model is to provide a kind of antitheft locking-type bolt pair of new structure, and it can realize effective antitheft effect, can also realize dismantling purpose.The secondary technological scheme of the antitheft locking-type bolt that the utility model provides, its major technique content is: a kind of antitheft locking-type bolt pair, this bolt pair is a sunk fixing bolt pair, and its bolt one end is provided with a special-shaped multi-arris body nut, is the gap of inserting the spanner spanner between this nut and the counterbore.
The another kind of technological scheme that realizes the foregoing invention purpose is: a kind of antitheft locking-type bolt pair, and this bolt pair is a sunk fixing bolt pair, its bolt is provided with a special-shaped multi-arris body nut, is the gap of inserting the spanner spanner between this nut and the counterbore.
The secondary technological scheme of the antitheft locking-type bolt that the utility model proposes; be designed to the structure of the counterbore sheath of nut or nut; both protected nut or nut not by unauthorised broken; the Allen wrench instrument also can't probe into wherein; implement to force the twisting dismounting; and special-shaped nut or nut structure then must just can enter gap between counterbore and nut or the nut by the endoporus of special use and nut body or the corresponding wrench of nut body shape; rotarily open demounting bolt or lock bolt smoothly; thereby reach antitheft technical purpose of tearing open, present technique can be widely used in power equipment and install; technical fields such as water conservancy equipment installation.
Description of drawings
Fig. 1 to Fig. 6 is respectively a plurality of enforcement structure sectional views of the antitheft locking-type bolt of the utility model pair
Fig. 7 is the cross sectional representation of nut.
Embodiment
The disclosed antitheft locking-type bolt pair of the utility model is a sunk fixing bolt pair, as shown in Figure 1, its bolt 1 one ends are provided with a special-shaped multi-arris body nut 2, its profile as shown in Figure 7, the size of its length of side quantity and each length of side can arbitrarily be provided with according to actual conditions, press the difficulty that its shape is copied Wrench to increase, and form the various series product of variation.Nut 2 falls into counterbore 6 at stationary state; this counterbore 6 is the counterbore with the bolt concentric, between nut 2 and the counterbore 6 for inserting the gap of spanner 4 spanners, and counterbore 6 degree of depth more preferably greater than or equal the nut height; after the bolt locking, the counterbore wall constitutes the sheath of protection nut.As shown in Figure 2, this bolt pair is except that bolt 1 one ends are provided with a special-shaped multi-arris body nut 2, cooperate also to be provided with bolt 1 and sink to fixed nut 3, nut 3 has the special-shaped multi-arris body identical with nut 2, nut and its counterbore 6 ' between for inserting the gap of spanner 4 spanners, its counterbore degree of depth more preferably greater than or equal the nut height.Of the present utility modelly one implement structure as shown in Figure 3 again, its structure constitutes: the bolt pair also comprises a cap colalr gasket 20, is provided with at tightening state nut 2 with its bolt 1 concentric on the cap colalr gasket 20 and sinks to counterbore 6 in it.The secondary structure of implementing of bolt as shown in Figure 4, it includes the bolt 1 with special-shaped multi-arris body nut 2, the nut 3 of the same special-shaped multi-arris body that cooperates with bolt 1 spiral, cap colalr gasket 20 and nut collar 30, be equipped with counterbore 6 on cap colalr gasket 20 and the nut collar 30 with bolt 1 concentric, 6 ', after fastening, nut 2 and nut 3 fall into counterbore 6 respectively, 6 ' in, its counterbore wall has constituted nut 2, the sheath of nut 3, at nut 2 and counterbore 6, nut 3 and counterbore 6 ' the gap in insert the spanner of the special spanner 4 identical with its shape, enforcement is tightened or unscrews dismounting, the described counterbore degree of depth more preferably greater than or equal nut, the nut height.Another kind of structure of the present utility model constitutes, as Fig. 5, its bolt 1 and body 7 one that are fixed, cooperate with bolt 1 and to be provided with a special-shaped multi-arris body nut 3, bolt 1 passes center fixed body 8, this center fixed body 8 is provided with and bolt 1 concentric counterbore 6, is the gap of inserting spanner 4 spanners between this nut 3 and the counterbore 6; Implement in the structure at Fig. 6, be provided with nut collar 30 between nut 3 and the center fixed body 8, nut collar 30 be provided with the counterbore 6 of bolt 1 concentric ', nut 3 and its packing ring counterbore 6 ' the gap for inserting the spanner of the special spanner 4 identical with its shape, the height of its counterbore preferably also should be more than or equal to the nut height.
