Drawings
FIG. 1 is a schematic view of the external structure of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in the figure, the high-strength anti-theft fastening nut assembly comprises a bolt 1, an inner nut 2, an outer nut 3 and a lock pin 4, wherein the inner nut 2 is in threaded connection with the bolt 1, the outer nut 3 is rotatably sleeved outside the inner nut 2, the outer nut 3 covers the inner nut 2, a through hole is formed in the side surface of the outer nut 3, a corresponding blind hole is formed in the side surface of the inner nut 2, and the lock pin 4 is inserted into the blind hole and the through hole to lock the inner nut 2 and the outer nut 3 so that the inner nut 2 and the outer nut 3 cannot rotate relatively.
As the utility model discloses an optimize structure: the outer wall of the inner nut 2 and the inner wall of the outer nut 3 are in running fit through a group of balls 5 which are arranged in an annular mode, specifically, an annular groove is formed between the outer wall of the inner nut 2 and the inner wall of the outer nut 3, a plurality of circular grooves matched with the balls in shape are uniformly formed in the annular groove, the balls 5 are embedded into the circular grooves, and the principle is similar to that of a ball bearing.
As the utility model discloses an optimize structure: the outer end of the lock needle 4 is provided with a fixing ring, the fixing ring is connected with a pull wire 6, and the pull wire 6 is used for pulling the lock needle 4 out of the through hole and the blind hole.
As the utility model discloses an optimize structure: the outer part of the outer nut 3 is of an outer hexagonal structure, and the outer hexagonal structure is convenient for screwing the nut.
As the utility model discloses an optimize structure: the outer nut 3 is including cup jointing outer nut pipe portion 30 outside the interior nut 2 and the outer nut top 31 of the interior nut 2 upper end of cover for outer nut 3 wraps the interior nut 2 is complete, makes the people be difficult for seeing the utility model discloses an interior outer nut's bilayer structure.
During the use, insert outer nut 3 and inner nut 2 with lock pin 4, make outer nut 3 and inner nut 2 locking, when rotating outer nut 3 like this, inner nut 2 rotates thereupon, has twisted the nut after and extracts lock pin 4 through 6 acting as go-between, when rotating outer nut 3 again like this, inner nut just can not rotate, and the thief is not knowing like this the utility model discloses a double-layer nut structure and under the condition of not preparing lock pin 4, can't twist the opening the utility model discloses a.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
