Abstract
The utility model discloses a kind of concave-convex pairs of anti-loose nut structure, including knurled nut and recessed nut, and the knurled nut is provided with tapered end and nut end, and tapered end outer rim is provided with screw thread, and centre is provided with shrinkage joint, and groove is equipped between tapered end and nut end；Threaded bellmouth is provided in the nut body of the recessed nut, and bellmouth is threadedly coupled with the tapered end of knurled nut.The elimination in gap between normal thread may be implemented in the utility model, and frictional resistance greatly enhances, and improves the friction anti-loosing effect of double nut, and locking installation and removal are very convenient.
Description
Technical field
The utility model relates to a kind of nut, in particular to a kind of concave-convex pairs of anti-loose nut structure.
Background technique
Locking thread friction is at present with one of widest locking thread method, it is by nut thread and screw rod
Frictional force between screw thread reaches anti-loosing effect.For it is some it is locking require higher occasion, generally use two nuts to top
It is locking, rapidly due to its installation, convenient disassembly, thus be common locking measures in mechanical equipment.However, in some operating conditions
Under conditions of comparing badly, for example, when equipment is influenced by factors such as shock and vibrations or varying load, to top pairs of anti-loose nut
The effect is unsatisfactory, equipment operation a period of time, will cause locking failure.The reason is that: after first nut is screwed into screw rod,
It is influenced by matrix (connector) reaction force, screw thread and the screw flight side of nut are compacted, but this pressing force
It is weakened, or even disappears after with being screwed into of second nut.So, the pretightning force of double nut is just changed,
Preventing the frictional resistance of thread looseness may reduce or momentary loss, loosen due to screw thread is self-locking because losing, thus to top double nut
Anti-loose structure Shortcomings in place of.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of concave-convex pairs of anti-loose nut structure, to improve double spiral shells
The locking reliability of mother's friction.
The utility model uses following technical scheme, a kind of bumps pairs of anti-loose nut structure, including knurled nut and recessed nut,
It is characterized in that, the knurled nut is provided with tapered end and nut end, and tapered end outer rim is provided with screw thread, and centre is provided with contraction
Seam is equipped with groove between tapered end and nut end；Threaded bellmouth, and taper are provided in the nut body of the recessed nut
Hole is threadedly coupled with the tapered end of knurled nut.
The tapered end is truncated cone or cone, and taper is 1:3~5.
The shrinkage joint width is 1~3mm, the inner side edge of depth to groove.
Compared with prior art, beneficial effect is the utility model: the elimination in gap between normal thread may be implemented, rub
It wipes resistance to greatly enhance, improves the friction anti-loosing effect of double nut, and locking installation and removal are very convenient.
Detailed description of the invention
Fig. 1 is the separate structure partial cutaway schematic of the utility model.
Fig. 2 is the utility model integral installation structure use state diagram.
In figure: 1. knurled nuts, 11. nut ends, 12. tapered ends, 13. shrinkage joints, 14. grooves, 2. recessed nuts, 21. nuts
Body, 22. bellmouths, 3. screw rods, 4. connected compcnents.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.Referring to Fig. 1 and Fig. 2, a kind of concave-convex double spiral shells
Female anti-loose structure, including knurled nut 1 and recessed nut 2, which is characterized in that the knurled nut 1 is provided with tapered end 12 and nut end
11, and 12 outer rim of tapered end is provided with screw thread, centre is provided with shrinkage joint 13, and groove is equipped between tapered end 12 and nut end 11
14；Threaded bellmouth 22, and the tapered end of bellmouth 22 and knurled nut 1 are provided in the nut body 21 of the recessed nut 2
12 are threadedly coupled.The tapered end 12 is truncated cone or cone, and taper is 1:3~5.13 width of shrinkage joint is 1
~3mm, the inner side edge of depth to groove 14.
Embodiment: such as Fig. 1, an a kind of better embodiment of concave-convex pairs of anti-loose nut structure of the utility model is selected
Two internal thread nuts, one of nut are machined to knurled nut 1, and specific knurled nut 1 is divided to for two parts, the left side
Protrusion part is the tapered end 12 with certain taper, and taper is 1:3~5, and 12 outer rim of tapered end is threaded, and the right is
A part of former nut constitutes nut end 11, groove 14 is equipped between tapered end 12 and nut end 11, among tapered end 12
The shrinkage joint 13 of depth to 14 inner side edge of groove is provided with along axial direction, shrinkage joint width is 1~3mm.The present embodiment is preferably bored
Shape end 12 is truncated cone, and taper 1:4, shrinkage joint width is 2mm.Another nut is machined to recessed nut 2, specific recessed spiral shell
The shape of mother 2 are as follows: the part fallen in is to be machined with threaded bellmouth 22 in nut body 21, taper be 1:3~
5, so that bellmouth 22 is threadedly coupled with the tapered end 12 of knurled nut 1.22 taper of the present embodiment bellmouth is 1:4, with circular cone
The taper of platform shape tapered end 12 matches for 1:4.Such as Fig. 2, when installing and using, screw rod 3 is first passed through into one group of connected compcnent 4 and is used in combination
Knurled nut 1 compresses, and recessed nut 2 outwardly, is then installed on screw rod 3, bellmouth 22 is inwardly by the tapered end 12 for making knurled nut 1
It is corresponding with tapered end 12.With being screwed into for recessed nut 2, the screw thread of tapered end 12 and bellmouth 22 is mutually crowded according to face principle is carved
Pressure keeps the diameter at groove 14 more slightly smaller than the diameter that bottom is bored in tapered end 12,13 elasticity of shrinkage joint is pressurized due to being provided with groove 14
Become smaller, internal screw thread and the external screw thread on screw rod 3 of such tapered end 12 mutually compress, and gap is eliminated, and it is reliable to reach connected compcnent 4
The locking purpose of friction.
