Abstract

The invention discloses a looseness alarm bolt with an installation self-checking function. The looseness alarm bolt comprises a bolt head, a bolt rod and a nut installed on the bolt rod in a threadedmode, wherein the bolt head and the bolt rod are integrally formed, an audible and visual alarm is installed on the surface of the bolt head in an embedded mode, and a first wire and a second wire are installed on the audible and visual alarm. Turnoff and closing of a self-checking alarm circuit are achieved through the nut, the self-checking alarm circuit can be closed for self-checking in the thread installation process, then the self-checking alarm circuit is turned off for real-time monitoring, detection and alarm are timely, and careless omission is avoided.

Description

technical field [0001] The invention relates to the field of engineering spare parts, in particular to a loose alarm bolt with installation self-check. Background technique [0002] In building construction, water conservancy construction and other projects, bolts are often used as fasteners for two connecting parts. Fastening by bolts can make the two connecting parts more fit and more stable. However, during the use of bolts, as the connection Vibration of parts will cause loosening, and loosening of bolts may cause safety accidents. [0003] The existing bolts have a bolt-nut structure and do not have the function of loosening detection. The loosening of the bolts is detected by means of personnel inspection. The detection is not timely, and effective early warning cannot be effective in a short period of time, and it is prone to omissions. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art that there i...
