Anticreep nut

Technical Field

The utility model relates to the technical field of nuts, in particular to a drop-proof nut.

Background

The nut is also called a nut and is a fixing tool, the center of the nut is provided with a hole, and the inner side of the hole is provided with threads; nuts are often used with screws of comparable size to secure the relevant engaging portions.

The traditional screw structure of the bolt and the nut is generally connected with a screw column of the bolt by screwing a threaded hole of the nut with the same screw thread with a screw column of the bolt; however, the prior art has the following disadvantages: when the existing bolts and nuts are in threaded connection and shake in vibration, irregular fluctuation and the like, the threaded structure of the nuts and the bolts is easy to fall off and even damage the nuts and the bolts.

Disclosure of Invention

The utility model mainly aims to provide an anti-drop nut, which reduces the influence of vibration on the screwing structure of the nut and a bolt, avoids the loosening and gradual drop of the nut when the nut vibrates, and can effectively solve the problems in the background technology.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a anticreep nut, includes the anticreep nut, a plurality of anticreep recesses that are used for preventing the slippage are seted up to anticreep nut one side lateral wall, the inside joint of anticreep recess has the anticreep convex ball that is used for the cooperation to realize the anticreep, just anticreep convex ball fixed connection is in anticreep packing ring one side surface, through tightening gradually and make the anticreep recess card that anticreep nut one side was seted up insert anticreep convex ball increase contact surface, reduce the influence of vibrations to the spiro union structure of nut and bolt, avoid the nut not hard up and drop gradually when taking place the vibrations.

Further, the side wall of the anti-drop gasket, which is far away from the anti-drop nut, is provided with a friction surface with rough surface, the friction force is increased through the friction surface, the loosening condition generated when the nut vibrates is further reduced, and the stable structure of the threaded connection is relatively increased.

Further, a first through hole is formed in the center of the anti-drop nut, a second through hole which is matched with the first through hole in size is formed in the center of the anti-drop gasket, and the bolt is inserted through the first through hole and the second through hole to form a threaded structure with the bolt.

Further, the area of the anti-falling convex ball is smaller than the size of the anti-falling groove, the anti-falling convex ball is smaller than the anti-falling groove to enable the anti-falling washer to be prevented from being static and unable to rotate due to the friction surface when the anti-falling washer is screwed, so that the anti-falling convex ball clamps the anti-falling nut, and the anti-falling nut cannot be screwed.

Compared with the prior art, the utility model has the following beneficial effects:

1. the anti-falling groove formed in one side of the anti-falling nut is clamped into the anti-falling convex ball to increase the contact surface, so that the influence of vibration on the screwing structure of the nut and the bolt is reduced, and the nut is prevented from loosening and gradually falling off when vibrating.

2. The friction force is increased through the friction surface, so that the loosening condition of the nut during vibration is further reduced, and the stable structure of the screwed connection is relatively increased.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 and 2, a anticreep nut, including anticreep nut 1, a plurality of anticreep recesses 3 that are used for preventing the slippage are seted up to anticreep nut 1 one side lateral wall, the inside joint of anticreep recess 3 has the anticreep convex ball 4 that is used for the cooperation to realize the anticreep, and anticreep convex ball 4 fixed connection is in anticreep packing ring 2 one side surface, through screwing up gradually and make the anticreep recess 3 card that anticreep nut 1 one side was seted up insert the anticreep convex ball 4 increase the contact surface, reduce the influence of vibrations to the spiro union structure of nut and bolt, avoid the nut not hard up and come off gradually when taking place the vibrations.

As shown in fig. 1 and 3, the side wall of the anti-drop washer 2, which is far away from the anti-drop nut 1, is provided with a friction surface 7 with rough surface, the friction force is increased through the friction surface 7, the loosening condition generated when the nut vibrates is further reduced, and the stable structure of the screwed connection is relatively increased.

As shown in fig. 1, a first through hole 5 is formed in the center of the anti-drop nut 1, a second through hole 6 which is matched with the first through hole 5 in size is formed in the center of the anti-drop washer 2, the area of the anti-drop convex ball 4 is smaller than the groove size of the anti-drop groove 3, the anti-drop convex ball 4 is smaller than the anti-drop groove 3 to prevent the anti-drop washer 2 from being static and unable to rotate due to a friction surface 7 when the anti-drop washer is screwed, the anti-drop nut 1 is clamped and unable to be screwed, and the anti-drop washer is penetrated through the first through hole 5 and the second through hole 6 to form a screwed structure.
