Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a circular lock nut with locking ring.
In this embodiment, referring to fig. 1 to 4, the circular lock nut with the locking ring includes a circular nut body 2 having a first threaded hole 1, a step 3 extending from the outer periphery of the circular nut body 2, a first wrench groove 4 being provided on the step 3 at equal intervals, and a locking ring 5, wherein one end of the circular nut body 2 is provided with a circular groove 6 concentric with the first threaded hole 1, the circular groove 6 is provided with an elastic tapered ring 7, the tapered ring 7 is provided with a second threaded hole 8 coaxial with the first threaded hole 1 and having the same diameter as the first threaded hole 1, the wall thickness of the tapered ring 7 is gradually increased from the top to the bottom wall of the circular groove, and the locking ring is threadedly connected to the tapered ring, so that the locking ring can be tightened inward when the locking ring rotates towards the bottom wall of the circular groove.
When the locking ring is used, the locking ring is screwed towards one side of the wall thickness, the conical ring is forced to contract inwards, the gap of the threads on the threaded hole is reduced, and the friction between the threaded hole and the screw rod is increased, so that the anti-loosening and anti-returning effects are achieved. Wherein, the conical ring and the locking ring are connected by screw thread, which is convenient for assembly and disassembly. The conical ring has elasticity, can be made of metal with good elasticity such as spring steel and the like, and can realize micro-deformation under the tightening action of the locking ring.
Specifically, the locking ring 5 is provided with at least two notches 9 at equal intervals.
After the technical scheme is adopted, through setting up the incision, for the shrink of conical ring provides the deformation allowance, avoid conical ring to damage because of excessive deformation, improve life.
