Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and more specifically to a double-threaded misaligned anti-loosening fastening nut. Background Technology

[0002] In the field of mechanical parts technology, anti-loosening fastening nuts are widely used mechanical parts. However, in their actual application, the prior art (authorization announcement number CN118855831A) has problems such as too many parts and complex structure.

[0003] Therefore, how to provide a nut with a simple structure that uses a double-threaded misaligned anti-loosening fastening nut is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a double-threaded misaligned anti-loosening fastening nut with a simple structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-threaded misaligned anti-loosening fastening nut includes: a nut body and a chamfer on the outer edge of the nut body and a first thread and a second thread on the inner wall, the first thread and the second thread being coaxially arranged, anti-loosening wear-resistant rubber washers being placed at the upper and lower ends of the inner wall of the nut body, anti-loosening protrusions being provided on the upper and lower surfaces of the nut body, and a double-threaded bolt for use.

[0007] Preferably, the nut body is a hexagonal nut.

[0008] Preferably, the first thread and the second thread are staggered, with the first tooth of the first thread and the second tooth of the second thread having the same pitch and size, but opposite directions of rotation.

[0009] Preferably, the double-threaded bolt is used in conjunction with a double-threaded misaligned anti-loosening fastening nut. The first thread and the second thread of the double-threaded bolt are arranged in a misaligned manner, with the same teeth, pitch, and size, but opposite directions of rotation.

[0010] As can be seen from the above technical solution, compared with the prior art, the double-threaded misaligned anti-loosening fastening nut disclosed in this utility model has a simpler structure than existing nuts. This utility model achieves the anti-loosening and fastening effect of the nut through the double-threaded misaligned arrangement. Through the double-threaded misaligned arrangement, the bolt can generate two directions of rotation, making the bolt-nut more secure. Attached Figure Description

Obviously, the drawings described below are only embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model discloses a double-threaded misaligned anti-loosening fastening nut, including a nut body 1, a chamfer 6 on the outer edge of the nut body 1, and a first thread 2 and a second thread 3 on the inner wall. The first thread 2 and the second thread 3 are arranged coaxially. Anti-loosening wear-resistant rubber washers 4 are placed at the upper and lower ends of the inner wall of the nut body. Anti-loosening protrusions 5 are provided on the upper and lower surfaces of the nut body. There is also a double-threaded bolt 7 that needs to be used in conjunction.

[0017] The nut body is a hexagonal nut, which is not easy to slip or rotate.

[0018] The first thread 2 and the second thread 3 are staggered. The first tooth 21 of the first thread 2 and the second tooth 31 of the second thread 3 have the same pitch and size, but their rotation directions are opposite. The staggered arrangement of the two threads with opposite rotation directions can generate two opposite forces in the bolt. When the bolt is under working conditions such as vibration, the two opposite forces generated will make the nut-bolt tighter.

[0019] The anti-loosening and wear-resistant rubber washer 4 is made of high-strength and wear-resistant material. The anti-loosening and wear-resistant rubber washer will generate a tightening force on the bolt. Its anti-loosening and wear-resistant material makes it difficult for the nut or bolt to rotate, thereby achieving the effect of anti-loosening and tightening.

[0020] The nut has anti-loosening protrusions 5 evenly distributed on its upper and lower surfaces. The anti-loosening protrusions can increase the contact area with the bolt head, thereby achieving the effect of anti-slip and anti-loosening. The shape and density of the anti-loosening protrusions can be selected by those skilled in the art.

[0021] The double-threaded bolt 7 is used in conjunction with the double-threaded misaligned anti-loosening fastening nut. The first thread 71 and the second thread 72 of the double-threaded bolt 7 are arranged in a misaligned manner. Their teeth, pitch and size are the same, but their directions of rotation are opposite. Due to the distribution of the first and second threads of the bolt, the bolt can rotate in both directions of rotation of the nut.

[0022] The double-threaded misaligned anti-slip fastening nut is used in conjunction with a double-threaded bolt. Two double-threaded misaligned anti-loosening fastening nuts with different directions of rotation can be installed on the double-threaded bolt. In practical applications, under conditions such as vibration, the forces of the two nuts rotating in opposite directions can cancel each other out, thereby achieving a situation where the more vibration occurs, the tighter the fastening becomes, thus achieving the effect of preventing loosening and fastening.

[0023] This utility model discloses a double-threaded staggered anti-loosening fastening nut. Compared with existing nuts, the structure of this utility model is simpler. This utility model achieves the anti-loosening and fastening effect of the nut through the double-threaded staggered arrangement. Through the double-threaded staggered arrangement, the bolt can generate two directions of rotation, making the bolt-nut more secure.

[0024] The above description of the disclosed embodiments enables those 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 general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
