Specific implementation mode
For elaboration the content of present invention is better described, expansion explanation is carried out with reference to schematic diagram and embodiment：
Shown in Fig. 1-Fig. 4, the present invention provides a kind of locking bindiny mechanisms, are fixed in the mounting hole 2 of panel 1；Packet
Include the connection main body 3 for being connected through a screw thread the component product being fixed on panel 1, check washer 5 and stop nut 6；Connection
The bottom of main body 3 is equipped with the end of thread 4 that can be passed through mounting hole 2 and be screwed by stop nut 6, check washer 5
Centre, which is equipped with, accommodates the mounting hole 7 that passes through of the end of thread 4, and 7 edge of mounting hole is equipped with locating convex block 8, the side of the end of thread 4 be equipped with
8 compatible positioning groove 9 of locating convex block；The surrounding edge of check washer 5 is equipped with the dog-ear for being affixed to 1 surface of panel tilted
Portion 10 is evenly distributed with anti-slop serrations 11, check washer 5 and anti-slop serrations 11 on the end face that stop nut 6 is in contact with check washer 5
Corresponding position be equipped with anti-skidding convex ribs compatible with anti-slop serrations 11 12.
Further, the side surface that anti-slop serrations 11 are located at installation direction is rounded surface 13.
Further, the outer side wall surface of stop nut 6 is equipped with anti-sliding burr 14.
Further, the bottom of stop nut 6 is equipped with fixed bayonet 15.
Further, check washer 5 is elastic sheet metal.
Specifically, stop nut 6 is by being clamped in check washer 5 by panel 1 with the threaded connection of the end of thread 4 and connecting master
Between body 3, the wedge angle that the dog-ear portion 10 of 5 surrounding edge of check washer is pointed is withstood on 1 surface of panel, plays increase friction
The effect of power.Check washer 5 is made of flexible metal, and 10 wedge angle of dog-ear portion will produce elasticity under the action of installing force
Deformation, the elastic force of generation can increase the frictional force engaged between the end of thread 4 and stop nut 6, and playing prevents nut back rotation
Effect.Increased frictional force makes nut also not allow to be also easy to produce loosening under vibration environment.
Further, there are anti-slop serrations 11, the spacing between adjacent anti-slop serrations 11 is more than anti-skidding convex ribs 12 on stop nut 6
Both sides distance, anti-slop serrations 11 be located at installation direction a side surface be rounded surface 13, stop nut 6 installation be torqued-up to
After prescribed torque, anti-skidding convex ribs 12 can directly or press slip over rounded surface 13 after slide into the gap between adjacent anti-slop serrations 11
Space, it is larger with the frictional force of anti-skidding convex ribs 12 because of the 11 non-rounding in left side of anti-slop serrations, it is needed than installation when dismantling stop nut 6
The power of Shi Geng great, therefore by the cooperation with anti-skidding convex ribs 12, play the role of 6 rotation stop of stop nut.
Skid resistance strip rotates the end of thread 4 of 6 mounting related components product of stop nut, fixed bayonet 15 convenient for user with hand
It can coordinate assembly wrench (not shown) that installation is fixed, it is convenient and strength-saving.
Further, when the installation direction of stop nut 6 is rotation (clockwise) to the right, the oblique table in right side of anti-slop serrations 11
Face is rounded surface 13, and round and smooth curved surface can facilitate anti-skidding convex ribs 12 to slide into the clearance space between adjacent anti-slop serrations 11
It is interior.Likewise, if Design of Screw Thread be the installation direction of reversed i.e. stop nut 6 for rotation (counterclockwise) to the left when, anti-slop serrations
11 left side skewed surface is rounded surface 13.It only needs to swap left and right anti-slop serrations 11 towards the side of installation direction.
The present invention also has second embodiment, and described in Fig. 4, in a second embodiment, check washer 5 of the invention includes can
Dismounting separation or assembled integral first part 16 and second part 17, first part 16 and the stitching portion of second part 17 are equal
The splicing slot 19 for being correspondingly provided with outwardly extending spelling joint 18 and being inwardly recessed；Splicing slot 19 and the shape of spelling joint 18 are mutually fitted
Match.Check washer 5 can be integrated in the present embodiment, also can be used as 2 assembled parts of dismounting, and any portion after fractionation is
Still have 2 dog-ear portions 10 and elastic sheet metal material, integrally weaken a point elasticity, remain able to provide partial elastic with
And 10 wedge angle frictional force of part dog-ear portion, while being conveniently not necessarily to remove stop nut 6 to realize the fast of check washer 5 by splicing
Fast installation and replacement.
Specifically, the stitching portion of first part 16 and second part 17 is at head and the tail two, the stem of first part 16 and the
The tail portion of two parts 17 is equipped with circular spelling joint 18, and receiving circle is equipped at the tail portion of first part 16 and the head of second part 17
The round splicing slot 19 of the hollow out of shape spelling joint 18 makes first part 16 and the by the splicing of spelling joint 18 and splicing slot 19
Two parts 17 are spliced integrally, convenient quickly to be replaced to check washer 5 in the case where stop nut 6 is not dismantled, and are saved
The time of maintenance.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Technical solution of the present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
It can so modify to the technical solution recorded in previous embodiment, or which part technical characteristic is replaced on an equal basis
It changes；And these modifications or replacements, the essence for various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution
God and range.
