Abstract
The present invention provides a kind of swivel nut of locking key, and it is made up of the swivel nut body with internal and external threads and 4 locking keies, and the swivel nut body includes integrally formed connecting portion and tight lock part, and external screw thread is on connecting portion, and internal thread runs through connecting portion and tight lock part；The tight lock part excircle axial direction is provided with locking key provided with 4 equally distributed swallow-tail form keyways, the swallow-tail form keyway interpolation；Escape is provided with the cylindrical circumferential direction in the middle of the connecting portion and the tight lock part.The present invention is used and is integrally formed, and in ladder shaft-like, it is easy to implement the equal strength of swivel nut, and beneficial to spacing and installation, after external screw-thread hole is screwed into, swivel nut is realized by the shaft shoulder of tight lock part and positioned, because it is more than the radial depth of swallow-tail form keyway along tight lock part radial height after locking key insertion swallow-tail form keyway, so the swallow-tail form keyway interior energy that locking key is inserted into tight lock part realizes the circumferentially fixed of swivel nut, so as to ensure that being reliably connected for swivel nut and matrix.
Description
Technical field
The present invention, which is related to, belongs to mechanical manufacturing field, concretely relates to a kind of swivel nut of locking key.
Background technology
Swivel nut is the insert developed for protection non-ferrous metal screwed hole, it is adaptable to is threadedly coupled, screws in and be fastened on
In the screwed hole of one of connected piece, standard female is formed.Swivel nut has higher hardness and preferable surface roughness, often
Applied to the environment of high intensity internal thread is needed, antidetonation, anti-pulling ability are strong.Loaded in screw or nut, have mitigate ridge by
Uneven and anti shock and vibration the effect of power, can improve the fatigue strength of screw thread, reduce abrasion and the corrosion resistance of screw thread, and
Energy dispersive stress protection matrix screw thread, greatly prolongs the service life of matrix.In addition, swivel nut can also be on protocorm screw thread
When dropout or random tooth, as the means of reparation, and whole matrix will not be caused to scrap, and easy to maintenance, fast, economical.Plain edition
Swivel nut is easily loosened, come off due to no self-lock ability, and when torque is larger, swivel nut is usually rotated together with screw, so that
Cause swivel nut backing out from part base solid screwed hole, cause the damage of part base solid screwed hole, bring very big to maintenance
Trouble, even results in renewal part matrix.So, it is badly in need of a kind of swivel nut of self-locking, the intensity of screw thread can either be ensured, do not allowed again
Easily loosen, come off, make connection more firm.
The content of the invention
To overcome drawbacks described above, it is an object of the invention to provide a kind of swivel nut of locking key, by swivel nut connecting portion with
It is fitted close to realize the locking of swivel nut between tight lock part, so as to avoid the loosening of swivel nut with coming off.
A kind of swivel nut of locking key, it is made up of the swivel nut body with internal and external threads and 4 locking keies, the swivel nut
Body includes integrally formed connecting portion and tight lock part, and external screw thread is on connecting portion, and internal thread runs through connecting portion and tight lock part；
The tight lock part excircle axial direction is provided with 4 equally distributed swallow-tail form keyways, and the swallow-tail form keyway interpolation is provided with locking
Key；Escape is provided with the cylindrical circumferential direction in the middle of the connecting portion and the tight lock part.
Further, it is more than the dovetail key along tight lock part radial height after the locking key insertion swallow-tail form keyway
The radial depth of groove.
Further, the diameter of the tight lock part is more than the major diameter of thread of the connecting portion.
A kind of swivel nut of locking key of the present invention, its advantage is：The present invention is used and is integrally formed, and in multi-diameter shaft
Shape, is easy to implement the equal strength of swivel nut, and beneficial to spacing and installation, after it is screwed into external screw-thread hole, swivel nut passes through tight lock part
The shaft shoulder realize positioning, due to locking key, to insert the radial direction that it is more than swallow-tail form keyway along tight lock part radial height after keyway deep
Degree, so the swallow-tail form keyway interior energy that locking key is inserted into tight lock part realizes the circumferentially fixed of swivel nut.
Brief description of the drawings
Fig. 1 is the structural representation of the swivel nut of locking key of the present invention；
Fig. 2 is the K direction views of the screw bushing structure schematic diagram of locking key of the present invention.
Shown in figure, 1- swivel nuts body, 2- connecting portions, 3- escapes, 4- tight lock parts, 5- swallow-tail forms keyway, 6- locking keies.
Embodiment
The principle and feature of the present invention are described below in conjunction with example, example is served only for explaining invention, not
For limiting the scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of swivel nut of locking key, it is locked by the swivel nut body 1 with internal and external threads and 4
Key 6 is constituted, and the swivel nut body 1 includes integrally formed connecting portion 2 and tight lock part 4, and external screw thread is on connecting portion 2, interior spiral shell
Line runs through connecting portion 2 and tight lock part 4；The excircle axial direction of tight lock part 4 is provided with 4 equally distributed swallow-tail form keyways 5, institute
State and locking key 6 is inserted with swallow-tail form keyway 5；It is provided with the cylindrical circumferential direction in the middle of the connecting portion 2 with the tight lock part 4
Escape 3.
Further, after the insertion swallow-tail form keyway of locking key 6 of the swivel nut of the locking key its along the radial height of tight lock part 4
More than the radial depth of the swallow-tail form keyway 5.
Further, the diameter of the tight lock part 4 of the swivel nut of the locking key is more than the major diameter of thread of the connecting portion 2.
The present invention is achieved in the following ways：First, the connecting portion of swivel nut body is screwed into matrix screwed hole, led to
Cross the tight lock part shaft shoulder and realize positioning, install swivel nut body, locking key is then inserted into swallow-tail form keyway, due to locking key insertion
The radial depth that it is more than swallow-tail form keyway along tight lock part radial height after keyway, so locking key to be inserted to the dovetail of tight lock part
Shape keyway interior energy realizes the circumferentially fixed of swivel nut, so as to ensure that being reliably connected for swivel nut and matrix, with shock resistance and wear-resisting
The function of damage, the need for can meeting high intensity occasion, and extends the service life of matrix.
Protection scope of the present invention is not limited to the technical scheme disclosed in embodiment, every skill according to the present invention
Any modification, equivalent substitution and improvements that art is substantially made to above example etc., each fall within protection scope of the present invention.
