Anti-blocking nozzle for cooling heat treatment quenching machine

The utility model relates to an anti-blocking nozzle for cooling a heat treatment quenching machine, and belongs to the technical field of quenching machines. Comprising a mounting frame, a horizontally-arranged extension block is integrally formed on the side face of the mounting frame, a vertically-arranged filtering mechanism is arranged on the extension block in a penetrating mode, a fixing unit is arranged on the side face of the mounting frame, and the fixing unit surrounds the filtering mechanism, so that the filtering mechanism is fixedly connected with the mounting frame; a nozzle body is arranged at the bottom of the extending block and fixed to an outlet of a filtering mechanism, and the filtering mechanism filters cooling liquid and then flows to the nozzle body. The filter is used for filtering cooling liquid, blockage of the nozzle body is reduced, the water outlet capacity of the nozzle is guaranteed, and the service life of the nozzle body is prolonged. 本实用新型涉及一种热处理淬火机冷却用防堵塞喷嘴，属于淬火机技术领域。包括安装架，
