Abstract
The utility model discloses hexagonal self-locking nut, there is outer-hexagonal body, tapped hole is established in outer-hexagonal body, it is characterized in that: cambered surface chamfering is established in the upper-end surface of outer-hexagonal body, cambered surface chamfering is established three place's triangular indentations, three place's triangular indentations stagger 120 degree mutually, the base of triangular indentations is towards tapped hole central straight to the hole wall of tapped hole, the base width of triangular indentations is greater than 4mm, and the degree of depth of triangular indentations is less than 0.5mm, and the top of triangular indentations faces toward the top of the horn of outer-hexagonal body.It is not very smooth workplace that the utility model is applied to fastening surface, and have reliable retaining and screw-threaded coupling function concurrently, nut appearance quality is good.
Description
Technical field
The utility model relates to a kind of Fastener products, is specifically related to a kind of improvement invention of hexagonal self-locking nut.
background technique
In Fastener products, considerable part is had to be the hexagonal self-locking nut of threaded locking function, the screw-threaded coupling mode of hexagonal self-locking nut is locked nothing more than nylon spacer, several modes such as tinsel locking and deformed threads locking, deformed threads locking is that the thread pitch by changing a certain section of tapped hole realizes, although deformed threads locking can be in different ways, but all can break the appearance quality of ring nut largely, and usually cause the pitch deformation amount of internal thread very among a small circle large, when very easily there is nut screwing clamping, torsion is excessive, after being threaded through, this portion deforms pitch then comparatively easily recovers normal pitch, do not have due screw-threaded coupling function, it is unreliable to lock, in addition, hexagonal self-locking nut does not possess stopping function usually, even if having also is adopt retaining pattern structure, being not suitable at fastening surface is not particularly that the fastening occasion of very smooth (as mounting hole end face has burr not easy to clean) uses near central position.
Summary of the invention
In view of current known technology Problems existing, the technical problems to be solved in the utility model is to provide one to be applied to fastening surface not to be very finishing operations occasion, to have reliable retaining and screw-threaded coupling function concurrently, the hexagonal self-locking nut that nut appearance quality is good.
The utility model is implemented by the following technical programs:
Hexagonal self-locking nut, there is outer-hexagonal body, tapped hole is established in outer-hexagonal body, it is characterized in that: cambered surface chamfering is established in the upper-end surface of outer-hexagonal body, cambered surface chamfering is established three place's triangular indentations, three place's triangular indentations stagger 120 degree mutually, the base of triangular indentations is towards tapped hole central straight to the hole wall of tapped hole, the base width of triangular indentations is greater than 4mm, and the degree of depth of triangular indentations is less than 0.5 mm, and the top of triangular indentations faces toward the top of the horn of outer-hexagonal body.The lower end surface of outer-hexagonal body is provided with three place's triangle boss, and three the top of the horn positions of three place's triangle boss hexagon are outside arranged, and two, the outside arm of angle of triangle boss overlaps with the arm of angle of outer-hexagonal body.
Have employed the hexagonal self-locking nut of technique scheme, compared with prior art have the following advantages: 1. because the lower end surface of outer-hexagonal body arranges triangle boss as fastening end face, carry out fastening so can avoid installing the irregular place of fastening surface to object, triangle boss is equivalent to the retaining decorative pattern of custom design simultaneously, can play retaining effect; 2. triangular indentations can change the thread pitch of length, and the area of indentation is comparatively large, is convenient to the control of depth of indentation, both combine and just make pitch deformation area large, but amount of deformation is little, thus make nut have reliable screw-threaded coupling function, simultaneously because impression is shallow, guarantee that nut appearance quality is good.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is end face direction of the present utility model view,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is direction, bottom surface of the present utility model view.
Embodiment
Details and the working principle of the utility model specific embodiment is described in detail below in conjunction with accompanying drawing:
As shown in the figure, hexagonal self-locking nut of the present utility model, have outer-hexagonal body 1, establish tapped hole 2 in outer-hexagonal body 1, cambered surface chamfering 4 is established in the upper-end surface of outer-hexagonal body 1, cambered surface chamfering 4 is established three place's triangular indentations 3, three place's triangular indentations 3 stagger 120 degree mutually, and the base of triangular indentations 3 is towards tapped hole central straight to the hole wall of tapped hole 2, and the base width of triangular indentations 3 is greater than 4mm, the maximum depth of triangular indentations 3 is less than 0.5 mm, and the top of triangular indentations 3 faces toward the top of the horn of outer-hexagonal body 1; The lower end surface of outer-hexagonal body 1 is provided with three place's triangle boss 5, three place triangle boss 5 and also mutually staggers 120 degree, and three the top of the horn positions of three place's triangle boss 5 hexagon 1 are outside arranged, and two, the outside arm of angle of triangle boss 5 overlaps with the arm of angle of outer-hexagonal body 1.
Because hexagonal self-locking nut of the present utility model is provided with three place's triangular indentations in upper-end surface, not only make nut have reliable screw-threaded coupling function, and nut appearance quality is good; Simultaneously because hexagonal self-locking nut of the present utility model is provided with three place's triangle boss in lower end surface, not only making nut can be applicable to fastening surface is not very finishing operations occasion, and possesses reliable stopping function.
