Novel anti-theft anti-looseness bolt and nut locking device

Abstract

The embodiment of the invention discloses a novel anti-theft anti-looseness bolt and nut locking device. The device comprises a bolt, an anti-looseness nut is connected to the side wall of the bolt ina screwed mode, a locking mechanism is arranged at the lower end of the anti-looseness nut, a lock bolt hole is formed in the position, corresponding to the locking mechanism, of the side wall of thelower end of the bolt, and a locking assembly for limiting the locking mechanism is arranged in the lock bolt hole. According to the novel anti-theft anti-looseness bolt and nut locking device, the locking assembly is arranged, the locking assembly can be used in a mode of cooperating with the locking mechanism, when the anti-looseness nut is screwed on the bolt, a lock bolt body on the locking assembly can be embedded into the tooth surface to form a locking structure, therefore, the phenomenon that the bolt is easily loosen due to strong impact cannot occur, and then the situation that a large amount of time is consumed for maintenance is avoided; and meanwhile, when the locking structure is formed, the lock bolt body is always embedded into the tooth surface so that reverse rotation cannot occur to the locking nut again, then the anti-theft effect is achieved, the structure is compact, the flexibility is high, and mounting is convenient.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of connectors, and in particular to a novel anti-theft and anti-loosening bolt and nut locking device. Background technique [0002] Screws are common products in daily life, and they are closely related to life. Screws are a tool for fastening the parts of objects step by step by using the physical and mathematical principles of the oblique circular rotation and friction of objects. Screw is a general term for fasteners, a daily colloquial language. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws for TVs, electrical products, musical instruments, furniture, etc.; large screws for engineering, construction, and bridges. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As ...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a novel anti-theft and anti-loosening bolt and nut locking device on which a locking assembly is provided, which can be used in conjunction with a locking mechanism. When the anti-loosening nut is screwed on the bolt, the lock can be The locking tongue body on the locking component is embedded in the tooth surface to form a locking structure. Even if the bolt is subjected to a strong impact, it will not easily loosen, thus avoiding the situation of spending a lot of time on maintenance. At the same time, when the locking structure is formed Finally, the lock tongue body will always be embedded in the tooth surface, so the anti-loosening nut can no longer be reversed, and this has the effect of preventing theft. Its structure is compact, flexible, and easy to install, so as to solve the problem of At present, the common bolts and nuts on the market rely on friction to fasten the connection when they are fixed, but because they will be impacted and loosened, users need regular maintenance and reinforcement to prevent costly downtime or accidents. Its operation is cumbersome and complicated, and the screwed bolts and nuts are more convenient to disassemble and assemble, which makes some valuable fasteners very easy to be stolen after installation
