[0002] In mechanical equipment and structures, components connected by bolts and nuts are often subjected to external forces such as vibration and impact. These external forces can cause the nuts to loosen, which in turn affects the stability and safety of the entire equipment. Loose nuts can lead to a loss of stability in the fastener, potentially causing machine failures, equipment accidents, and even threats to personal safety. Therefore, measures are needed to prevent nut loosening. Nuts require special structural designs to prevent loosening under vibration or external forces. By preventing loosening, the nut can reduce wear and damage caused by loosening, thereby extending the service life of the fastener and equipment. In view of this, we propose a nut with an anti-loosening limiter. Utility Model Content

In view of this, we propose a nut with an anti-loosening limiter.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a nut with an anti-loosening limiter is provided, including an anti-loosening ring, characterized in that a limiting block is fixedly connected in an annular shape on the anti-loosening ring, a square hole is provided on the upper part of the limiting block, and a limit button that can be pressed is provided in the hole, the limit button is a right-angled triangular prism with its inclined surface facing upward and a square groove inside, a spring is placed in the square groove, a fixed protrusion is fixedly connected in the square hole on the limiting block, and the spring is sleeved on the fixed protrusion.

[0005] Furthermore, a long strip of nut limiting groove is vertically opened inside the nut, and the number of the nut limiting grooves is consistent with the limiting blocks on the anti-loosening ring. A plurality of rectangular button slots are opened on the top of the nut, and the button slots are opened on the left side of the nut limiting groove.

[0006] Furthermore, the nut is equipped with a slotted bolt, and the slotted bolt is vertically provided with a long strip of bolt limiting grooves, and the number of the bolt limiting grooves is consistent with the limiting blocks on the anti-loosening ring.

[0007] Furthermore, a square ring is fixedly connected to the slotted surface of the limit button, the area of ​​the square ring is consistent with the area inside the square hole opened on the upper part of the limit block, and the area of ​​the square hole is consistent with the area of ​​the slotted surface of the limit button.

[0008] Furthermore, the square groove opened inside the limit button matches the position of the fixed protrusion fixedly connected in the square hole on the limit block.

[0009] Furthermore, the height of the limit block cannot be longer than the height of the nut, the width of the limit block must be consistent with the nut limit groove and the bolt limit groove, and the length of the limit block must be greater than the depth of the nut limit groove but less than the sum of the depths of the nut limit groove and the bolt limit groove.

[0010] Compared with the existing technology, the utility model has the following beneficial effects: the nut with an anti-loosening limit piece cooperates with the limit block through the limit groove, so that the nut cannot rotate left or right, limits the axial movement of the nut, and achieves the stability of the fastening connection under vibration and external force conditions.
