Abstract
The utility model relates to a countersunk head swivel nut connection structure contains axle body, spindle nose, swivel nut and connecting screw, the spindle nose setting is served at one of axle body, swivel nut and spindle nose cooperation to be connected fixedly through connecting screw and spindle nose, the link of swivel nut is provided with the counter sink, and the nut part of connecting screw sets up in the counter sink, be provided with the annular knurl on the outer circumference of spindle nose, the spindle nose passes through annular knurl and swivel nut interference fit, the utility model discloses a countersunk head swivel nut connection structure, spindle nose pass through annular knurl and swivel nut interference fit to the cooperation connecting screw is fixed with the swivel nut, makes swivel nut and spindle nose can not take place relative rotation, and the annular knurl can select the reticulation structure to increase the grasp, the nut of connecting screw part sets up in the counter sink, avoids convex nut influence the use of swivel nut, and overall structure is stable, because annular knurl processing convenience has improved machining efficiency, has reduced the processing cost.
Description
Technical field
This utility model is related to a kind of attachment structure of swivel nut.
Background technology
It is generally used for coordinating with the axle of polished rod with externally threaded swivel nut, is fixed on axle, makes axle that there is threaded connection
Function；Axle sleeve has plurality of specifications, can be selected as needed, with certain versatility, and replaceable after wearing and tearing,
It is very easy to use；Swivel nut generally requires the respective outer side edges by groove and fin with axle, makes swivel nut relative with axle generation
Rotate, it is ensured that the stability of connection, but this connected mode needs to process the structure of groove and fin on axle or swivel nut, leads
Cause working (machining) efficiency low, and increased processing cost.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is：Propose a kind of attachment structure of swivel nut.
What technical solution of the present utility model was realized in：A kind of countersunk head swivel nut attachment structure, comprising axle body, axle
Head, swivel nut and attachment screw；The spindle nose is arranged on one end of axle body, and swivel nut and spindle nose coordinate, and by attachment screw with
Spindle nose is connected；The connection end of the swivel nut is provided with counter sink, and the nut portion of attachment screw is arranged in counter sink；Institute
State and be provided with the excircle of spindle nose annular knurl, spindle nose is by annular knurl and swivel nut interference fit.
Preferably, the diameter of the axle body and the external diameter of swivel nut are equal.
Preferably, the annular knurl on the spindle nose is reticulate structure.
Due to the utilization of above-mentioned technical proposal, this utility model has compared with prior art following advantages：
Countersunk head swivel nut attachment structure of the present utility model, spindle nose passes through annular knurl and swivel nut interference fit, and the spiral shell that is connected
Nail fixes swivel nut, makes swivel nut not relatively rotate with spindle nose, and annular knurl can select reticulate structure to increase grasp；Even
The nut portion for connecing screw is arranged in counter sink, it is to avoid the nut of protrusion affects the use of swivel nut, and overall structure is stable, due to
Annular knurl is easy to process, improves working (machining) efficiency, reduces processing cost.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is a kind of schematic diagram of countersunk head swivel nut attachment structure of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings illustrating this utility model.
As shown in Figure 1, a kind of countersunk head swivel nut attachment structure described in the utility model, comprising axle body 1, spindle nose 2, swivel nut
3 and attachment screw 4；The spindle nose 2 is arranged on one end of axle body 1, and swivel nut 3 coordinates with spindle nose 2, and by attachment screw 4 with
Spindle nose 2 is connected；The diameter of the axle body 1 is equal with the external diameter of swivel nut 3, when swivel nut 3 coordinates with deeper screwed hole, axle
Body 1 can be screwed into swivel nut 3, move without limitation on swivel nut 3；The connection end of the swivel nut 3 is provided with counter sink, attachment screw 4
Nut portion be arranged in counter sink, it is to avoid the nut of protrusion affects the use of swivel nut 3；Set on the excircle of the spindle nose 2
The annular knurl of reticulate structure is equipped with, spindle nose 2 passes through annular knurl and the interference fit of swivel nut 3, because annular knurl is this area common structure, therefore
It is not shown in figure.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it
It is interior.
