Embodiment
Below against attached drawing, by the description of the embodiment, to specific embodiment of the present utility model as involved Mutual alignment and connection relation, the effect of each several part and operation principle between the shape of each component, construction, each several part etc. make into The detailed description of one step:
As shown in attached drawing 1- attached drawings 3, the utility model is a kind of stop nut structure, and the stop nut structure includes Nut body 1, nut flange 2, structure in T shape between nut body 1 and nut flange 2, the nut body 1 and nut Engaging portion 3 in being set between flange 2, interior 3 position of engaging portion set concave part 4, and concave part 4 is arranged to along interior engaging portion 3 one weeks The ring channel structures of arrangement.Nut structure of the prior art, when screw bolt and nut body is connected stand under load with connected component, Bolt Tensile, the externally threaded pitch increase of bolt;And nut is compressed, the pitch of the internal thread of nut reduces.Bolt The difference in change increase of the pitch of the internal thread of externally threaded pitch and nut body, and difference in change with the first lap that screws (i.e. Close to connected component side) place is maximum, the change of the pitch of each circle (being gradually distance from connected component) thread upwards later Difference is successively decreased.Such structure, when screw bolt and nut body is connected stand under load with connected component, main load concentration is first Circle, fewer and fewer afterwards, the ridge later to the 8th circle is almost not subject to load, in this way, each external screw thread thread of external screw thread The load skewness between each internal thread thread of nut body, causes bolts and nuts body to be connected with connected component When threaded connection intensity decreases, in helicitic texture use easily occur pine turn problem.And locking spiral shell described in the utility model Parent structure, sets concave part, so so that nut body lower end has outstanding in the interior engaging portion of nut body 1 and nut flange 2 The effect put, when screw bolt and nut body is connected with connected component, the spiral shell outside thread and bolt inside nut body Tooth is screwed stress together, and the internal screw thread that nut body is located at close to connected piece side can be also stretched, its morphotropism Matter also will be identical with the ridge of bolt, so as to effectively reduce the difference in change of the pitch of different internal thread threads and outer spiral shell The difference in change of the different pitch of line thread so that the load distribution on each internal thread thread and external screw thread thread tends to be uniform, Load skewness and problem of stress concentration on the different threads of bolts and nuts body screw thread are effectively solved, improves bolt and spiral shell Threaded connection intensity when maternal body is connected with connected component, effectively improves bolt and nut anti-loosening property.The utility model institute The stop nut structure stated, it is simple in structure, when screw bolt and nut body is connected with connected component, it can effectively change bolt Load skewness and problem of stress concentration on threads different from nut body screw thread, improve bolts and nuts body and are connected Threaded connection intensity when relay part connects, effectively improves bolt and nut anti-loosening property.
The nut flange 2 includes flange lateral surface 5, and 5 surface of flange lateral surface sets the anti-skidding teeth that multiple tracks is protruded 6, the anti-skidding teeth 6 described in multiple tracks are configured to along 5 one weeks structures arranged by gap of flange lateral surface.Said structure, leads to The setting of anti-skidding teeth is crossed, when screw bolt and nut body is connected stand under load with connected component, the flange lateral surface of nut body Anti-skidding teeth fit together with connected component, in this way, anti-skidding teeth can be effectively increased frictional force, so as to prevent bolt Relatively rotate the problem of coming off during stress.
The concave part 4 is arranged to the structure that section is in the shape of the letter V, and the concave part 4 is configured to from nut sheet The structure that 3 position of interior engaging portion between body 1 and nut flange 2 extends to 1 direction of nut body.In this way, concave part forms ring Connected in star, when the screw bolt and nut body is connected stand under load with connected component, solves the different spiral shells of bolts and nuts body screw thread Load skewness and problem of stress concentration on tooth, improve threaded connection when bolts and nuts body is connected with connected component Intensity, improves bolt and nut anti-loosening property.
Anti-skidding teeth portion 7 is formed by the anti-skidding teeth 6 of multiple tracks that gap is arranged along flange lateral surface 5, anti-skidding teeth 6 are helical teeth Structure, the inside of nut body 1 set internal thread 8, bolt 9, the external screw thread 10 of bolt 9 are set with the internal thread 8 of nut body 1 It is screwed and is connected with the internal thread 8 of nut body 1.Said structure, the anti-skidding teeth 6 of multiple tracks form anti-skidding teeth portion 7, and anti-skidding teeth 6 are Helical teeth structure, in this way, after bolt is tightened with connected component spiral shell, nut body can produce a kind of trend for loosening slip, prevent Slip teeth portion 7 applies the pretightning force opposite with loosening the trend of slip just, can effectively prevent such trend for loosening slip, Improve frictional force.
The internal thread 8 includes multi-turn internal thread thread 11, often encloses between internal thread thread 11 there are pitch, described External screw thread 10 includes multi-turn external screw thread thread 12, and often there are pitch between circle external screw thread thread 12.
The nut flange 2 is loop configuration, and nut flange 2 is an integral structure with nut body 1.Said structure, Effectively increase the intensity of nut body, dependable performance in use, service life length.
Stop nut structure described in the utility model, groove is set in the interior engaging portion of nut body and nut flange Portion, so so that nut body lower end has the effect of suspension, when screw bolt and nut body is connected with connected component, spiral shell The thread of female body interior be screwed with the thread outside bolt together with stress, and nut body is located at close to connected piece side Internal screw thread can also be stretched, its deformation properties also will be identical with the ridge of bolt, so as to effectively reduce difference The difference in change of the difference in change of the pitch of internal thread thread and the different pitch of external screw thread thread so that each internal thread thread and outer Load distribution on screw thread thread tends to be uniform, realizes that load distribution is not on the different threads for changing bolts and nuts body screw thread Equal and problem of stress concentration, improves threaded connection intensity when bolts and nuts body is connected with connected component, effectively improves Bolt and nut anti-loosening property.Stop nut structure described in the utility model, it is simple in structure, it can effectively change bolts and nuts Load skewness and problem of stress concentration on the different threads of body screw thread, improve bolts and nuts body and connected component Threaded connection intensity during connection, effectively improves bolt and nut anti-loosening property.
Exemplary description is carried out to the utility model above in conjunction with attached drawing, it is clear that the utility model concrete implementation is simultaneously From the limitation of aforesaid way, if the various improvement that the methodology of the utility model and technical solution carry out are employed, or It is not improved that the design of the utility model and technical solution are directly applied into other occasions, the protection in the utility model In the range of.
