Abstract
The utility model discloses an anti-loosen screw cap. The screw hole of the screw cap is provided with an integrated forming slight convex-part screw tooth which can form slight convex surface, slight convex rib or slight convex ring. By adopting the structure, the anti-loosen screw cap can utilize the integrated forming convex-part screw tooth to facilitate no-clearance locking match to be formed at the screwed slight convex part between the screw cap and the screw, meanwhile, the utility model reaches the tight matching condition without a gasket, and saves the elements and working procedures.
Description
Technical field
The utility model relates to a kind of nut, especially a kind of can be locking, the nut of anticreep.
Background technique
As everyone knows, nut is to cooperate screw rod that object is locked together in together, this sealed everywhere as seen.Since be object is locked together in together, therefore as require the locking must the cushion cover packing ring must lock when therefore sealed, and general screwing togather all be sealed at interval,, borrow the elastic force of packing ring between sealed thread, to form tension and lock, make that screw rod and nut are sealed unlikelyly to get loose arbitrarily.For the higher locking operation of anti-loose requirement, generally use open washer, the high elasticity that the opening dislocation is opened has better tension locking effect.Therefore anti-loose the screwing togather of screw rod and nut all must be by gasket element at present.
Summary of the invention
The utility model main purpose is to provide a kind of jam nut, can not reach the purpose of locking by packing ring.
For achieving the above object, the utility model adopts following structure, and integrally formed dimpling portion thread is set in the screw of nut.Dimpling portion thread can form the dimpling face, dimpling rib or micro-projecting ring.
Adopt the jam nut of said structure can utilize integrally formed dimpling portion thread, make nut form gapless locking at the dimpling portion place that screws togather and cooperate, owing to do not reach the drive fit state, can save element and operation again simultaneously by pad with screw rod.

Embodiment
The utility model is mainly providing a kind of jam nut, is the thread that is formed with dimpling portion in screw 10.
The utility model first embodiment as shown in Figure 1 and Figure 2, screw 10 hole walls of nut 1 are formed with dimpling face thread 11, this dimpling face thread 11 is bordering on gapless micro-convex structure when being made as and screwing togather with the same specification screw rod, be no gap at dimpling face thread 11 places when nut 1 and screw rod are screwed togather and screw togather locking, have locking, anticreep and anti-ly fall etc. to locking effect.
Second embodiment of the present utility model as shown in Figure 3, Figure 4, nut 1 is formed with dimpling rib thread 12 in screw 10 hole walls, provide dimpling rib thread 12 places to have to be bordering on that no gap screws togather is locking, anticreep and anti-effect such as fall, this dimpling rib thread 12 is particularly useful for the few flat type nut of thread number.
The 3rd embodiment of the present utility model such as Fig. 5, shown in Figure 6, screw 10 hole walls of nut 1 are formed with micro-projecting ring thread 13, this micro-projecting ring thread 13 is positioned at the locking end position of nut 1, the hole wall that is micro-projecting ring thread 13 in locking end position is all shapes of ring, and is bordering on gapless screwing togather with the same specification screw rod at micro-projecting ring thread 13 places and cooperates.
Claims (4)
