Abstract
The utility model relates to a standard fasteners, in particular to an anti-loose and anti-theft combined nut whose structure is that a fastening nut is provided with an anti-loose and anti-theft cover whose anti-loose claw is matched with the screw threads of a screw bolt to be used for anti-loosing. The ratchet pawl of the anti-loose and anti-theft cover is matched with the ratchet slot of the nut, which can prevent the thief from disassembling the nut by an ordinary wrench, and thus the anti-theft performance is provided. The utility model with simple structure and novel design, can provide new actions and functions to the standard fasteners, can guarantee safety practically, and can exert positive role in the occasions of electric lines, military installations, etc.
Description
The utility model relates to standard fasteners, particularly have standard fasteners locking, anti-theft feature.
Existing standard fasteners, relatively Chang Yong bolt, nut fastener are in actual use, owing to reasons such as vibrations, easily take place loosening, make troubles for people's production, life, at this problem, people have invented binding nut, built-in type lock nut, can prevent the loosening of nut effectively.In fields such as power circuit, military installations, not only need for standard fasteners locking, but also need antitheft, safe and reliable to guarantee.
The purpose of this utility model just provide a kind of can be locking, extraordinary standard fasteners that again can be antitheft, thus satisfy the needs of some occasion.
Solution of the present utility model is: be provided with locking, antitheft cover on tightening nut, on locking, antitheft cover, be provided with locking pawl, screw-thread fit on it and the bolt, be used for lockingly, in addition, on locking, antitheft cover, also be provided with ratchet, cooperate with the sour jujube groove on the nut, make robber person not lay down nut with common wrench, have anti-theft, its detailed content is described below referring to accompanying drawing:
Of the present utility model locking, the structure of anti-theft nut compostle member is: be equipped with on the nut (5) that bolt (9) combines locking, antitheft cover (1), as shown in Figure 1, it is characterized in that having the locking of locking pawl (3), the inner circumference of antitheft cover (1) is provided with ratchet (2), have the sour jujube groove (6) that matches with ratchet (2) on (5) end faces of nut, when needs fixed connecting piece (10), with supporting nut (5) and bolt (9) link (10) is fixed and tightened, then with hand with locking, antitheft cover (1) is screwed into bolt (9), until twist with hand motionless till, and then it is tightened with special tool, locking pawl this moment (3) just tightly is attached on the flank of thread of bolt (9), meanwhile, locking, ratchet (2) on the antitheft cover (1) is because of in the sour jujube groove (6) on elastic reaction the snaps in supporting nut (5), make supporting nut (5) and locking, there is not the relative movement of counterrotating between the antitheft cover (1), like this because locking, locking pawl (3) on the antitheft cover (1) tightly is pressed on the flank of thread of bolt (9), anti-loose anti-theft cover (1) can not become flexible because of vibration, thereby supporting nut (5) is locking, ratchet (2) effect on the antitheft cover (1) also can not become flexible because of vibration down, has reached locking purpose.Because the profile of locking, antitheft cover (1) is cylindric, and common wrench can't be worked, can only just can make it loosening by the design specialized instrument, therefore have anti-theft feature.Of the present utility model being characterised in that on locking, antitheft cover (1) top has mounting hole (4), the design specialized instrument as shown in Figure 6, in the mounting hole (4) on cylindrical projection locking, the antitheft cover of insertion (1) on the special tool, locking, antitheft cover (1) can be tightened or unclamps.Locking, antitheft cover of the present utility model (1) is manufactured by metallic material or the composite material that contains metallic material, and locking like this, antitheft cover (1) has certain intensity, makes robber person be difficult for its destruction.
That the utility model provides is locking, the anti-theft nut compostle member is simple in structure, novel in design, its utilizes the structure be enclosed within locking, the antitheft cover on the nut, locking, the anti-theft of standard fasteners have been solved dexterously, make the standard fasteners of China that new effect and function arranged again, conscientiously guarantee safe and reliable, on power circuit, military installations and some other occasion, use, will bring into play its great positive role.
Accompanying drawing has been represented specific embodiments of the present utility model.
At first accompanying drawing is described:
Fig. 1 represents the A-A sectional drawing of locking, antitheft cover of the present utility model;
The plan view of Fig. 2 presentation graphs 1;
Fig. 3 represents the B-B sectional view of nut;
Fig. 4 represents the plan view of nut;
Fig. 5 represents sectional drawing of the present utility model;
Fig. 6 represents the structural drawing of special tool.
(1) locking, antitheft cover wherein; (2) ratchet; (3) locking pawl; (4) mounting hole; (5) nut; (6) sour jujube groove; (7) special tool; (8) cylindrical projection; (9) bolt; (10) need fixed connecting piece.
According to embodiment shown in the drawings, standard nut (5), bolt (9), on nut (5), have several sour jujube grooves (6), as Fig. 1, shown in 2, the cylinder tubbiness is locking, the helix that the height of the locking pawl (3) on the antitheft cover (1) is pressed on the bolt (9) distributes, as Fig. 3, shown in 4, total many two ratchets (2) cooperate with sour jujube groove (6) on the nut (5), locking, antitheft cover (1) has three spanner mounting holes (4) on the top, can unclamp by the formula of tightening in the insertion spanner mounting hole of the cylindrical projection (8) on the special tool (7) (4), locking, antitheft cover selects for use spring steel to make.
Claims (4)
1, locking, anti-theft nut compostle member, the nut that combines with bolt is provided with locking, antitheft cover, feature of the present utility model is that the inner circumference that has locking, the antitheft cover (1) of locking pawl (3) is provided with ratchet (2), has the sour jujube groove (6) that matches with ratchet (2) on an end face of nut (5).
