Abstract
The utility model relates to an anti-rotating draw nut which can be used for fixing bolts and can prevent rotating of the draw nut. The anti-rotating draw nut comprises a draw nut cap and a draw nut sleeve, one end of the draw nut and the draw nut cap are in an integrally connected structure, and the draw nut sleeve is provided with a hexagonal front half and a circular rear half. The anti-rotating draw nut has the advantages that the anti-rotating draw nut is novel and simple in structural design, capable of effectively preventing the draw nut after being positioned from rotating, safe and high in reliability.
Description
Technical field
The utility model relates to a kind ofly can be used for fixing bolt, can prevent from again drawing female rotation inhibiting of rotating to draw mother, belongs to female manufacturing field of drawing.
Background technique
CN2394047Y, title " inner nut connecting structure for thin metal shell ", its staking nut first half is provided with interior threaded hole, and the latter half of through hole that is provided with communicates with interior threaded hole, and rearward end is provided with a snap ring.During assembly connection, need the joint to bore a hole at the metal thin-wall closure member, be inserted in the staking nut, then make the staking nut rear form second snap ring with the pull mode, thereby closely be attached in the metal thin-wall closure member.Its shortcoming is: can not well prevent becoming flexible, coming off of nut in firm bolt.
The model utility content
Purpose of design: avoid the deficiency in the above-mentioned background technology, design and a kind ofly can be used for fixing bolt, can prevent from again drawing female loosening rotation inhibiting to draw mother.
Design proposal: in order to realize above-mentioned purpose of design.Draw master cylinder to overlap an end and draw female cap to be Integral connection structure, draw the front half part of master cylinder cover to be hexagon, the design that latter half part is rounded is technical characteristics of the present utility model.The purpose of doing like this is: the one, and utilize and draw the rounded rotation inhibiting that can reduce of master cylinder cover latter half part to draw mother to throw the interior resistance of object into, shortened the time of operation, improved operating efficiency; The 2nd, utilize and to draw the master cylinder cover near drawing female cap front half part to be hexagon, femalely can not rotate at interior of articles so that draw, but guarantee to draw female good solidity.
Technological scheme: a kind of rotation inhibiting is drawn mother, comprises drawing female cap and drawing the master cylinder cover, describedly draws master cylinder to overlap an end and draws female cap to be Integral connection structure, draws the front half part of master cylinder cover to be hexagon, and latter half part is rounded.
The utility model is compared with background technique, and the one, structural design is novel, simple; The 2nd, the mother that draws after effectively preventing from locating rotates, and safety reliability is high.
Description of drawings
Fig. 1 is that rotation inhibiting is drawn female right elevation.
Fig. 2 is that rotation inhibiting is drawn female plan view.
Fig. 3 is that rotation inhibiting is drawn female stereogram.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of rotation inhibiting is drawn mother, and it comprises draws female cap 1 and draw master cylinder cover 2, describedly draws master cylinder to overlap 2 one ends and draws female cap 1 to be Integral connection structure, draws the front half part of master cylinder cover 2 to be hexagon, and latter half part is rounded.The described master cylinder of drawing is overlapped 2 front half part interior smooth.Describedly draw master cylinder to overlap 2 latter half part inside to be threaded.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of model utility mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (3)
