Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 8, an easy-to-install hexagonal flange-faced locknut includes:

the nut comprises a hexagonal nut body 1, wherein a flange face 3 is fixedly arranged on one end face of the hexagonal nut body 1, the flange face 3 and the hexagonal nut body 1 are integrally formed, a friction face for increasing the friction force between the flange face 3 and a contact face is arranged on the flange face, a notch 11 is formed in one side face of the hexagonal nut body 1, and a fixing hole 12 is formed in the lower end face of the notch 11;

the anti-loosening buckle 2 comprises a clamping part 21 and a handle 22, a rotating shaft 23 is fixedly arranged on the clamping part 21, and the total height of the clamping part 21 and the rotating shaft 23 is smaller than that of the open groove 11, so that the clamping part can be conveniently installed in the open groove; the rotating shaft 23 is installed in the fixing hole 12, the anti-loosening buckle 2 is rotatably installed in the slot 11, the anti-loosening buckle 2 rotates in the forward direction to be separated from the bolt, and the anti-loosening buckle 2 rotates in the reverse direction to be abutted against the bolt.

Through the side installation at the hexagon nut body anti-loosening, when the nut was screwed up with bolt or screw rod, anticlockwise rotation handle, the most advanced of clamping part will contradict each other with bolt or screw rod, restriction nut and bolt or screw rod between relative rotation, played locking effect effectively.

When the locking buckle is used, the rotating shaft can be directly installed in the fixing hole through the groove, the locking buckle can be fixedly installed in the groove without other auxiliary tools or parts, and the locking buckle is convenient to detach.

The friction surface adopts a sawtooth 31 structure, the width and the depth of the sawtooth 31 are gradually reduced to zero from outside to inside, the outer ring of the nut can be enabled to have the sawtooth structure by the design, but the inner ring is not affected, and when the nut is screwed down, the inner ring does not have the sawtooth, so that the outer thread of a screw rod or a bolt contacted with the inner ring can not be damaged, and meanwhile, the nut is also convenient to screw down. The saw teeth 31 are uniformly distributed on the circumference, which is a circumscribed circle of a regular hexagon. The friction surface is arranged on the flange surface, so that when the nut is screwed down, the friction force between the flange surface and the contact surface is increased, the nut is not easy to loosen, and the purpose of preventing looseness is achieved.

As shown in fig. 8, the outer side of the junction of the gripping part 21 and the handle 22 is rounded, thus increasing the maximum angle of rotation of the entire check button in the slot about the rotation axis.

The surface of the clamping part 21 abutting against the bolt is provided with a tip 24. The tip 24 facilitates interference with the external threads of the bolt or screw to limit loosening.

The clamping part 21, the handle 22 and the rotating shaft 23 are integrally formed, so that the clamping part, the handle and the rotating shaft 23 are not required to be assembled, and the assembling processes are reduced.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
