Abstract
A multiple anti-loosening nut combinational structure is provided with an axial penetrating screw hole in the center, the top of the screw hole is provided with an upper flange ring along the axial direction, and an anti-loosening steel plate is riveted inside including a center connecting hole and an inner circumference connecting edge. The bottom of the screw hole is provided with a lower flange ring and a conical anti-loosening washer is riveted outside which is narrow on the top and wide at the bottom. As the screw cap is fastened outside the screw, the anti-loosening washer produces anti-pressure elasticity and the anti-loosening steel plate is clamped on the diagonal diameter of the screw thread, the structure achieves the multiple anti-loosening effects.
Description
Technical field
The utility model relates to a kind of multiple jam nut composite structure, refers to a kind of jam nut composite structure that installs additional in conjunction with locking steel disc in upper end and lower end lock washer especially.
Background technique
General bolt all is provided with a predetermined thread spindle, and the central authorities of nut then are provided with a tapped hole, to cooperate the thread spindle of interlocking bolt.
In actual interlocking operation, the thread spindle of bolt places the through hole for the treatment of fixed block, again with the tapped hole interlocking of nut on the thread spindle of bolt, bolt and nut are clamped treat fixed block.
But under the situation for the treatment of the frequent vibrations of fixed block, bolt and nut get loose easily, even reach nut on the thread spindle and treat to install additional between the fixed block indivedual pads, and the vibrations that also can't thoroughly the solve nut phenomenon that gets loose.And this nut and pad be all independent indivedual kenels, causes the puzzlement of stock control and the upright assembling of group relatively, and influence installation efficiency.
Summary of the invention
And the purpose of this utility model is promptly providing a kind of multiple jam nut composite structure, its nut is except tapped hole lock bolt own, specially add the elastic force that compresses of lock washer, and locking steel disc is clamped on the screw thread clino-diagonal of bolt, produces multiple locking effect.And nut, locking steel disc and lock washer triplicity are one, make things convenient for the upright assembling of stock control and group, improve on-the-spot installation efficiency.
For reaching above-mentioned purpose, the utility model nut central authorities are provided with a tapped hole that axially runs through, on the tapped hole top around along a upper flange ring axially is set, so that the locking steel disc that rivet clasp one contains center blocked hole and interior all clampings limit thereof to be set in inside; And the tapped hole bottom is on every side along the axial flanged ring that is provided with, externally to be nested with rivet clasp one up-narrow and down-wide conical lock washer.
In possible embodiments, the upper flange ring top riveting of this nut goes out all flangings in, and the bottom riveting of lower protruding edge ring goes out a periphery flanging.

Fig. 1 is the stereogram of the utility model embodiment jam nut;
Fig. 2 is the upright preceding three-dimensional exploded view of Fig. 1 jam nut group;
Fig. 3 is the sectional view of Fig. 1 jam nut;
Fig. 4 is the preliminary interlocking phase diagram of Fig. 3 jam nut;

Specific implementation method
Relevant the utility model is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof are enumerated possible embodiments now and cooperated the drawing explanation, so that global design more is tending towards is clear.
At first, see also Fig. 1, the utility model jam nut (10) is provided with the tapped hole (11) of an axial up/down perforation equally in centre, and nut (10) periphery also can be made into other suitable shape except being made as cerioid.And this nut (10) mainly focuses on installing additional a locking steel disc in a upper end (20) and a lower end lock washer (30), to produce multiple locking effect.And nut (10), locking steel disc (20) are one with lock washer (30) triplicity, to make things convenient for stock control, improve on-the-spot installation efficiency.
Nut (10) is being assembled locking steel disc (20) and lock washer (30) before, and as shown in Figure 2, on every side along a upper flange ring (12) axially is set, tapped hole (11) bottom is on every side then along the axial flanged ring (13) that is provided with on tapped hole (11) top.In the upper flange ring (12) of nut (10), place one and contain the locking steel disc (20) of center blocked hole (21), and week have two relative clamping limits (22) at least in the blocked hole (21).Upper flange ring (12) top of nut (10) is become interior all flangings (14) (Fig. 1,3 is consulted in cooperation) toward interior towards riveting, with the firm riveted joint of integrality locking steel disc (20).
Be nested with a lock washer (30) in lower protruding edge ring (13) outside of nut (10) in addition, this lock washer (30) is set as up-narrow and down-wide conical lamellar body, and it contains a top center hole (31), and a more roomy base ring limit (32).Lower protruding edge ring (13) bottom of nut (10) is become periphery flanging (15) (consulting Fig. 3) toward the outwash riveting, firmly rivet lock washer (30) with integrality.In possible embodiments, center hole (31) movable sheath of lock washer (30) is assigned in lower protruding edge ring (13) periphery of nut (10), and after the riveted joint combination, lock washer (30) can constitute free rotary state.
In preliminary interlocking state shown in Figure 4, the thread spindle (41) of bolt (40) passes two and treats the relative through hole (52) of fixed block (50), (51), nut (10) on the thread spindle (41) of bolt (40), makes base ring limit (32) contact of lock washer (30) treat fixed block (50) surface with tapped hole (11) interlocking then.
When continuing lock nut (10) with Wrench immediately, lock washer (30) is made its base ring limit (32) compel outward as shown in Figure 5 to open by powerful extruding.Therefore except nut (10) locking screw axle (41), add the powerful elastic force that compresses of lock washer (30), and the distortion of the clamping limit (22) of locking steel disc (20) is clamped on the screw thread clino-diagonal of bolt (40), and secure bond two is treated fixed block (50), (51) really, reach multiple locking effect, therefore nut (10) also can not produce loosening phenomenon even under the long-term vibration situation.
In conjunction with global designs such as locking steel disc and lock washers, can reach multiple locking effect according to the utility model nut one, and make things convenient for the upright assembling of stock control and group, improve on-the-spot installation efficiency, can utilize on the industry.
Above illustrated embodiment is only with for conveniently illustrating the utility model, not from the utility model spirit category, be familiar with the industry skill personage various simple and easy distortion and the modification that can do, must include in following claim scope.
