Description

A kind of screwed retaining ring part
Technical field
The utility model belongs to connection technical field of fastening, is specifically related to a kind of screwed retaining ring part.
Background technique
Nut is the most frequently used connection fastening piece of mechanical field, the nut of general use is common standard fastening piece mostly, under the effect of shock and vibration or heavy load, frictional force between screw pair reduces or pop-off gradually, thus it is loosening to occur being threaded, even fastening piece comes off, loses, and machinery can be made thus to break down.Under a lot of occasion, people can use lock nut to replace common standard nut at present, in case nut occurs loosening phenomenon in the process used.But the lock nut complex structure used now, manufacture cost is high, and is destructive locking mode mostly, and nut connects fastening rear dismounting difficulty, can not again utilize.
Claimant has applied for the utility model patent of locking-type lock nut in 2013-01-31, the notification number of this utility model patent is 203081978U, this locking-type lock nut solves the problem of existing lock nut well, but this locking-type lock nut will open restraining groove on stud, add difficulty of processing, improve cost of production.
Model utility content
For prior art Problems existing, the purpose of this utility model is to design the technological scheme providing a kind of screwed retaining ring part.
Described a kind of screwed retaining ring part, comprise stud, described stud one end is provided with nut, threaded coupling nut on described stud, it is characterized in that described stud comprises the first stud section and the second stud section, screw thread in the first described stud section and the second stud section is oppositely arranged, the first described stud section is threaded screwed retaining ring, threaded coupling nut in the second described stud section, described screwed retaining ring is in the outside of nut, described nut is provided with elastic lock tongue near the end face of screwed retaining ring, described screwed retaining ring is provided with the lock groove with elastic lock tongue adaptation, described elastic lock tongue protrudes from the surface of nut and connects spacing in lock groove.
Described a kind of screwed retaining ring part, is characterized in that described screwed retaining ring is provided with bulge loop on the end face arranging lock groove.
Described a kind of screwed retaining ring part, is characterized in that described lock groove is provided with a circle in one week along screwed retaining ring, and described lock groove links together ringwise flexuose.
Described a kind of screwed retaining ring part, is characterized in that described elastic lock tongue is inclined on the upper-end surface of nut.
Described a kind of screwed retaining ring part, it is characterized in that described lock groove is triangular in shape, the end of described elastic lock tongue props up mutually with the side of lock groove.
Described a kind of screwed retaining ring part, is characterized in that the diameter of the first described stud section is less than the second stud section.
Above-mentioned a kind of screwed retaining ring part, structure is simple, reasonable in design, low cost of manufacture, and nut connects fastening rear convenient disassembly.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is structural representation of the present utility model.
In figure: 1-stud; 101-first stud section; 102-second stud section; 2-nut; 3-nut; 301-elastic lock tongue; 4-screwed retaining ring; 401-lock groove; 402-bulge loop.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of screwed retaining ring part comprises stud 1, one end of stud 1 is provided with nut 2, stud 1 comprises the first stud section 101 and the second stud section 102, screw thread in first stud section 101 and the second stud section 102 is oppositely arranged, first stud section 101 is threaded screwed retaining ring 4, and threaded coupling nut 3 in the second stud section 102, screwed retaining ring 4 is in the outside of nut 3.As preferred structure, the diameter of the first stud section 101 is less than the second stud section 102, is conducive to reducing costs on the one hand, effectively stops screwed retaining ring 4 to enter in the second stud section 102 on the other hand.
Nut 3 is provided with elastic lock tongue 301 near the end face of screwed retaining ring 4, and screwed retaining ring 4 is provided with the lock groove 401 with elastic lock tongue 301 adaptation, and elastic lock tongue 301 is inclined on the upper-end surface of nut 3.Lock groove 401 is specifically triangular in shape, and the end of elastic lock tongue 301 props up mutually with the side of lock groove 401.Lock groove 401 is provided with a circle in one week along screwed retaining ring 4, and lock groove 401 links together ringwise flexuose.Arranging a circle lock groove 401 rotates in the process of tightening at nut, elastic lock tongue 301 can connect locking with any one lock groove 401, and anti-loosing effect is good, uses flexibly.Screwed retaining ring 4 is provided with bulge loop 402 on the end face arranging lock groove 401.Bulge loop 402 is arranged on screwed retaining ring 4 inner ring edge, bulge loop 402 protrudes from the end face of screwed retaining ring 4, the end face that screwed retaining ring 4 tightens rear bulge loop 402 coordinates with nut 3, what reduce between elastic lock tongue 301 and screwed retaining ring 4 is stressed, make elastic lock tongue 301 not yielding, ensure the intensity of elastic lock tongue 301, increase anti-loosing effect.
Above-mentioned screwed retaining ring part in use, stud 1 is inserted on link, nut 3 is connected in the second stud section 102 of stud 1, then is connected in the first stud section 101 of stud 1 by screwed retaining ring 4, until the elastic lock tongue 301 of nut 3 connects spacing in the lock groove 401 of screwed retaining ring 4.Because the screw thread in the first stud section 101 and the second stud section 102 is oppositely arranged, in using process, elastic lock tongue 301 and lock groove 401, always together with close-fitting, make nut 3 can not loosen in the process used, ensure the reliability connected.When needs dismounting nut 3, only need screwed retaining ring 4 to screw out.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
