Bolt there is following defect during actual use：The bolt of prior art is in the equipment of vibration in use, easily sending out
It is raw to loosen the phenomenon dropped, so as to influence the functional reliability of equipment.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of anti-loosening bolt, Neng Gouyou
Effect prevents bolt looseness, improves the reliability that bolt is used, simple in construction, easy to use, easy to utilize.
To achieve the above object, the utility model proposes a kind of anti-loosening bolt, including nut, screw rod, tooth line, peace
Tankage, fixed mount, tooth-like part and spring, the side of the nut are fixed with screw rod, and the outer surface of the screw rod is provided with tooth line,
The side that the nut is connected with screw rod offers mounting groove, and the mounting groove surrounds the connecting portion of nut and screw rod, institute
State and fixed mount is slidably fitted with mounting groove, the fixed mount is provided with tooth-like part away from the side of nut, the fixed mount is close
Spring is connected between the side of nut and the bottom land of mounting groove.
Preferably, mounting groove design triangular in shape, the fixed mount is in the hollow type three being adapted with mounting groove
Prismatic designs, the depth of the mounting groove is slightly larger than the width of fixed mount.
Preferably, the quantity of the spring at least 3 and be distributed in mounting groove, the two ends of the spring is fix
Connection.
Preferably, the tooth-like part indention design, the depth of the tooth-like part is 0.3~0.5mm.
The beneficial effects of the utility model：The utility model is fixed with screw rod by the side in nut, in screw rod
Outer surface is provided with tooth line, and the side being connected in nut with screw rod offers mounting groove, and mounting groove surrounds nut and screw rod
Connecting portion, is slidably fitted with fixed mount in mounting groove, is provided with tooth-like part away from the side of nut in fixed mount, is leaned in fixed mount
Spring closely is connected between the side of nut and the bottom land of mounting groove, after bolt screws in object, due to nut and object
Outer surface is mutually extruded so that fixed mount is pressed into mounting groove, and the tooth-like part on fixed mount lunges the outer surface of object, spring
Also thrust is provided for fixed mount, effectively can be prevented bolt from voluntarily turning by the resistance from fixed mount when bolt is rotated
Move and loosen, compared with prior art, can effectively prevent bolt looseness, improve the reliability that bolt is used, it is simple in construction,
It is easy to use, it is easy to utilize.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of anti-loosening bolt of the utility model.
In figure：1- nuts, 2- screw rods, 3- teeth line, 4- mounting grooves, 5- fixed mounts, 6- tooth-like parts, 7- springs.
【Embodiment】
Refering to Fig. 1, a kind of anti-loosening bolt of the utility model, including nut 1, screw rod 2, tooth line 3, mounting groove 4, fixation
Frame 5, tooth-like part 6 and spring 7, the side of the nut 1 are fixed with screw rod 2, and the outer surface of the screw rod 2 is provided with tooth line 3, institute
State nut 1 and offer mounting groove 4 with the side that screw rod 2 is connected, the mounting groove 4 surrounds the connection of nut 1 and screw rod 2
Fixed mount 5 is slidably fitted with portion, the mounting groove 4, the fixed mount 5 is provided with tooth-like part 6 away from the side of nut 1, described
Fixed mount 5 is connected with spring 7 between the bottom land of the side of nut 1 and mounting groove 4, the design triangular in shape of mounting groove 4,
