Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bolts, and in particular relates to an anti-loosening bolt. Background Art
[0002] Bolts are the foundation of mechanical manufacturing, and their role can be described as "a little effort can make a great difference". On the surface, the output value of bolts only accounts for a few percent of the machinery industry. In fact, it brings much higher added value to key components and equipment. Bolts are indispensable in daily life and industrial production and manufacturing. Bolts are also called industrial rice. Electronic products, mechanical products, digital products, power equipment, electromechanical mechanical products. Bolts are also used in ships, vehicles, water conservancy projects, and even chemical experiments. During the connection process of traditional bolts, due to the vibration of the equipment, the nut may be reversed on the bolt, resulting in the loosening of the bolt.
[0003] The Chinese utility model patent with publication number CN215762735U discloses an anti-loosening bolt, which uses the principle of forward and reverse rotation to prevent the bolt from loosening. When the friction force fails, the reverse thread setting of the fastening nut and the locking nut increases the pre-tightening force of the locking nut when the fastening nut loosens slightly due to natural loosening or external vibration, thereby preventing the thread from loosening. At the same time, through the setting of the fastening nut external thread, the slot, the plug-in part and the locking nut external thread, when the fastening nut tends to loosen due to vibration or external force, the fastening nut external thread and the locking nut external thread interact with each other to play a self-locking role, thereby preventing the nut from loosening. However, the device still has some other problems. For example, the two nuts of the bolt are also matched and fixed by threads, so the threads on the bolt and the threads between the two nuts need to be precisely matched, which makes its processing process more difficult. Moreover, when the vibration frequency is high, the nuts may also loosen, so its anti-loosening effect is not very ideal. Utility Model Content
