Abstract
The utility model discloses a locknut, and aims to provide a locknut with enhanced locking force. The locknut is characterized in that all the corners at one end of a nut body are respectively protrusively provided with a supporting leg, an inner threaded hole sequentially comprises a first thread section, a second thread section and a third thread section in the direction from one ends of the supporting legs to the other end of the nut body, the thread pitch of the first thread section is larger than that of the second thread section, and the thread pitch of the second thread section is larger than that of the third thread section. The inner threaded hole comprises the multiple thread sections, and the thread pitches of all the thread sections are sequentially superposed, so that a screw is screwed down increasingly in the installation process, the locking force in the process of fastening the nut is increased, and the anti-loosing capacity of the nut is effectively improved; all the corners at one end of the nut body are respectively protrusively provided with one supporting leg so that the installed nut is more stable, stability of the installed nut is further improved, and the nut is not prone to loosing.
Description
Technical field
The utility model relates to a kind of nut, and more particularly, it relates to a kind of lock nut.
Background technique
Screw is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, the instrument of fastening implements parts by easy stages, therefore the nut being used in conjunction with screw just needs internal thread and lead screw to be used in conjunction with, together with being screwed in screw, nut is used for playing the role of fastening, but by common on the market nut when the fastening implements parts, because the pitch of internal thread is fixed, therefore the coupling mechanism force of screw when fastening is relatively stable, easily make nut in use get loose, therefore operator are in practical work process, often need the cooperation of multiple nuts just can reach the fixing of locking and relative position, to improve the steadiness being fastenedly connected, make nut be difficult for producing loosening.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of lock nut that improves coupling mechanism force.
For achieving the above object, the utility model provides following technological scheme: a kind of lock nut, comprise nut body, described nut body runs through and is provided with inner bolt hole in central authorities, each edges and corners of described nut body one end all convex with supporting foot, described inner bolt hole includes the first thread section, the second thread section and the 3rd thread section successively along supporting foot one end to the direction of the nut body the other end, the pitch of described the first thread section is greater than the pitch of the second thread section, and the pitch of described the second thread section is greater than the pitch of the 3rd thread section.
The outer side wall of described nut body is concaved with stamped recess, and the madial wall of described inner bolt hole is provided with punching press projection with respect to the position male of stamped recess.
Described supporting foot is obliquely installed to nut body outside.
The bottom of described supporting foot is provided with anti-skidding burr.
The pitch of described the second thread section is 1.1 times of the 3rd thread section pitch, and the pitch of described the first thread section is 1.2 times of the 3rd thread section pitch.
A kind of lock nut, comprise nut body, described nut body runs through and is provided with inner bolt hole in central authorities, each edges and corners of described nut body one end all convex with supporting foot, described inner bolt hole includes the first thread section, the second thread section and the 3rd thread section successively along supporting foot one end to the direction of the nut body the other end, the pitch of described the first thread section is greater than the pitch of the second thread section, and the pitch of described the second thread section is greater than the pitch of the 3rd thread section.By adopting technique scheme, inner bolt hole includes multiple thread sections, and the pitch of each thread section superposes successively, therefore screw is more stubborn tighter in installation process, has increased the coupling mechanism force of nut when fastening, has effectively improved the anti-loose ability of nut, and the supporting foot that each edges and corners of nut body all convex with, more steady after can making nut install, further improve the steadiness after nut is installed, make nut be difficult for producing loosening.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model lock nut;
Fig. 2 is the A-A sectional view in Fig. 1.
Reference character: 1, nut body; 11, inner bolt hole; 111, the first thread section; 112, the second thread section; 113, the 3rd thread section; 12, supporting foot; 121, anti-skidding burr; 13, stamped recess; 14, punching press projection.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model lock nut embodiment is described further.
A kind of lock nut, comprise nut body 1, described nut body 1 runs through and is provided with inner bolt hole 11 in central authorities, each edges and corners of described nut body 1 one end all convex with supporting foot 12, described inner bolt hole 11 includes the first thread section 111, the second thread section 112 and the 3rd thread section 113 successively along supporting foot 12 one end to the direction of nut body 1 the other end, the pitch of described the first thread section 111 is greater than the pitch of the second thread section 112, and the pitch of described the second thread section 112 is greater than the pitch of the 3rd thread section 113.Inner bolt hole 11 includes multiple thread sections, and the pitch of each thread section superposes successively, therefore screw is more stubborn tighter in installation process, increase the coupling mechanism force of nut when fastening, effectively improve the anti-loose ability of nut, and the supporting foot 12 that all convexes with of each edges and corners of nut body 1, more steady after can making nut install, further improve the steadiness after nut is installed, made nut be difficult for producing loosening.
The outer side wall of described nut body 1 is concaved with stamped recess 13, and the madial wall of described inner bolt hole 11 is provided with punching press projection 14 with respect to the position male of stamped recess 13.The outer side wall of nut body 1 is processed with stamped recess 13 with punch ram, make the madial wall of inner bolt hole 11 produce deformation with respect to the position of stamped recess 13, form the punching press projection 14 protruding, punching press projection 14 has increased frictional force and sealed degree when screw is screwed into nut, therefore increase the coupling mechanism force of nut, effectively improved the anti-loose ability of nut.
Described supporting foot 12 is obliquely installed to nut body 1 outside.Supporting foot 12 tilts laterally, has expanded the conflict scope of supporting foot 12, when being conducive to increase nut and installing and the frictional force of mounting plane, avoids nut in installation process, rotate or even slide, and is convenient to improve the steadiness after screw and nut screwing clamping.
The bottom of described supporting foot 12 is provided with anti-skidding burr 121.Anti-skidding burr 121 has increased when nut is installed and the frictional force of mounting plane, is conducive to improve the steadiness after screw and nut screwing clamping, avoids nut in installation process, rotate or even slide.
The pitch of described the second thread section 112 is 1.1 times of the 3rd thread section 113 pitch, and the pitch of described the first thread section 111 is 1.2 times of the 3rd thread section 113 pitch.By lot of experimental data gained, the pitch of the second thread section 112 is 1.1 times of the 3rd thread section 113 pitch, and the pitch of the first thread section 111 is 1.2 times of the 3rd thread section 113 pitch, belong to best test data, because the pitch difference of each thread section is excessive, can cause and tighten difficulty, finally cannot correctly be in place, and the pitch difference of each thread section is too small, can not increase the effect of coupling mechanism force, therefore the pitch of the second thread section 112 is 1.1 times of the 3rd thread section 113 pitch, and the pitch of the first thread section 111 is 1.2 times of the 3rd thread section 113 pitch, for optimum scheme.
