Abstract
The utility model discloses a loose-proof structure for a self-locking nut. The nut is provided with a locking ring with a ring-shaped groove. A plurality of troughs are opened on the inner wall of the ring-shaped groove. The ring-shaped groove is provided with a metal ring; the metal ring is provided with a plurality of spinal plates outstretching from the trough. The spinal plates tilt in the rotating direction of the nut. When the nut is screwed tightly, the spinal plates sliding along the thread of the screw will also be screwed tightly. If the nut is unscrewed, the spinal plates will press against the thread of the screw to ban the metal ring and thus the nut from reversing, thus achieve self-locking and loose-proof purposes.
Description
Technical field
The utility model relates to a kind of nut, refers to a kind of self-locking nut anti-loose structure especially.
Background technique
Locking nut can be applicable to various occasions, and for example inlet valve or the drain valve in the cistern just needs nut check.After this inlet valve or drain valve were installed in the water tank, it was provided with externally threaded end and stretches out from the mounting hole of water tank bottom, can lock by nut afterwards.And in general, inlet valve and drain valve promptly are installed in the cistern before dispatching from the factory, therefore in transportation process, because the vibration nut is probably loosening, behind the arrival market, the sales force can not check one by one, and nut locked one by one, if but do not check and occur the phenomenon of nut loosening, when then the Consumer uses, just seepy question might occur, thereby cause unnecessary trouble.The problems referred to above not only appear in the cistern, need use the occasion of locking nut for other, have similar problem equally and occur, and therefore how to make nut also can not become flexible under the vibration situation, are the problem that the dealer will consider at present.
Though a kind of self-locking nut is arranged at present, it can reach locking effect, but after this self-locking nut is in a single day locked, just can't dismantle, in other words, will destroy nut in case remove, even screw rod also will damage, and some screw rod is to be fixed on the product, and screw rod damages product and also can't re-use, thereby causes waste.
The model utility content
The purpose of this utility model is to provide a kind of self-locking nut anti-loose structure, and this nut has auto-lock function after locking, thereby can prevent to become flexible because of vibration.
Another purpose of the present utility model is to provide a kind of anti-loose structure of self-locking nut, its reach self-locking locking in, also be convenient to the dismounting and can not damage screw rod and nut.
For achieving the above object, technical solution of the present utility model is:
A kind of self-locking nut anti-loose structure, this nut is provided with a locking ring, has annular groove on this locking ring, and the inwall of this annular groove then has some grooves; Be provided with a metal ring in this annular groove in addition, above-mentioned groove stretches out thereby this metal ring is provided with some spinal plates, and the true dip direction of this spinal plate is for to screw direction along nut.
Described locking ring split is arranged at the top of nut, is provided with locating column in the bottom of this locking ring, and the end face of described nut then is provided with the positioning hole relative with this locating column.
Also be provided with on the described metal ring and somely be used to compress the annular groove sidewall and the shell fragment that metal ring chucking is fixing.
Described locking ring is shaped in the top of nut.
After adopting such scheme, because the utility model is provided with a locking ring on locking nut, then be provided with a metal ring with spinal plate in this locking ring, and the true dip direction of this spinal plate is for to screw direction along nut, like this when nut is screwed, spinal plate slides along screw flight, can be smoothly along with nut is locked together, but when making because of vibration that nut is oriented to unscrew the trend that direction rotates, because the spinal plate true dip direction of metal ring is contrary in unscrewing direction, so spinal plate will fasten on screw flight, and metal ring can't be reversed, and then nut can not be reversed, so promptly reach the locking purpose of self-locking.
In addition, after nut and locking ring split are provided with, remove nut as desire, only need artificial firmly contrary spin nut, make the locating column fracture of locking ring bottom, nut can screw out, locking ring then can screw off along hand of spiral, the all recyclable usefulness again of nut of pulling down and metal ring, screw rod can be not destroyed yet, can use repeatedly.

Embodiment
As shown in Figure 1, what the utility model disclosed is a kind of locking nut, described nut 1 top is provided with a locking ring 2, the top of this locking ring 2 has annular groove 21, the inwall of this annular groove 21 then has some grooves 22, in addition, also be provided with locating column 23 in the bottom of this locking ring 2, the end face of described nut 1 then is provided with the positioning hole 11 relative with this locating column 23.
Be provided with a metal ring 3 in the annular groove 21 of described locking ring 2, this metal ring 3 is provided with some spinal plates 31, the true dip direction of this spinal plate 31 is for to screw direction along nut, in addition, also be provided with some shell fragments 32 on this metal ring 3, these some shell fragments 32 are used to compress annular groove 21 sidewalls after metal ring 3 places in the annular groove 21 of described locking ring 2, thereby metal ring 3 chuckings are fixing.
The utility model shown in Fig. 2,3, earlier is put in the annular groove 21 of locking ring 2 with described metal ring 3 in use, and the spinal plate 31 that makes metal ring 3 stretches out from the groove 22 of annular groove 21 inwalls; Then, again nut 1 is aligned the locating column 23 of locking ring 2 bottoms with its positioning hole 11, nut 1 is linked to each other with locking ring 2; Afterwards, nut 1 is locked on the screw rod 4 of desire locking together with locking ring 2,, therefore in screwing process, can make smoothly on the locking ring 2 and move, make nut 1 locking because spinal plate 31 true dip directions of described metal ring 3 are identical with the locking direction.And after nut 1 locking, when making because of vibration that nut 1 is oriented to unscrew the trend that direction rotates, because spinal plate 31 true dip directions of metal ring 3 are contrary in unscrewing direction, therefore spinal plate 31 will fasten on the screw thread of screw rod 4, make metal ring 3 can't reverse (as Fig. 4), and because the positioning hole 11 between nut 1 and the locking ring 2 makes both interlocks with locating column 23, thereby nut 1 can not be reversed, so promptly reach the locking purpose of self-locking.
When desire is removed nut 1, only need artificial firmly contrary spin nut 1, make locating column 23 fractures of locking ring 2 bottoms, at this moment, nut 1 can screw out, and locking ring 2 then can screw off along hand of spiral, nut 1 and all recyclable usefulness again of metal ring 3 pulled down, screw rod can be not destroyed yet.
Need to prove that described locking ring 2 also can be shaped in the top of described nut 1, perhaps below, but integrated structure when removing nut, needs rigid dismounting, screw rod is with destroyed.In addition, described locking ring 2 also can be arranged at the below of nut 1.
