Description

Technical Field

[0001] The invention belongs to the field of locks, and in particular relates to a button lock. Background Art

[0002] In industrial production, the standby machine needs to be cranked and inspected regularly for a short time according to the different needs of the on-site pump conveying medium to ensure the integrity of the standby machine. The power needs to be cut off during the cranking and inspection process. In this process, the equipment is usually powered off by personnel, and then the button is locked. By isolating the button from the personnel, it is prevented from causing the equipment to start up by mistake due to improper operation by personnel, causing unnecessary safety accidents. However, according to a large number of production practices, the above operations are very troublesome, and the above process cannot completely control the power off. Due to the influence of the equipment electrical circuit, the stop signal of the button may suddenly terminate, thereby affecting the work of the microcomputer, causing the equipment to start up by mistake, causing unexpected safety accidents, and bringing harm to production management. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a button lock, which can disconnect the control circuit through a pressing part and send a continuous stop signal to the on-site microcomputer. The operation is simple, safe and reliable, and can effectively prevent the equipment from starting or shutting down by mistake, and has a good control effect.
