Nozzle mechanical sealing structure

Abstract

The invention discloses a nozzle mechanical sealing structure. The nozzle mechanical sealing structure comprises a pipeline, a spray head mechanism is arranged at the upper end of the pipeline, a locking mechanism is arranged on the surface of the spray head mechanism, the spray head mechanism comprises a threaded spray pipe, the threaded spray pipe fixedly communicates with the upper end of the pipeline, and a conical cylinder is fixedly connected to the upper end of the threaded spray pipe. The nozzle mechanical sealing structure has the beneficial effects that a fixing rod drives a clamping block to rotate, when the clamping block rotates, a vertical groove is driven to rotate, the vertical groove drives a threaded cylinder to rotate, threads on the surface of the threaded cylinder extrude threads on the inner wall of a threaded spraying pipe, and then the rotating line of the threaded cylinder moves upwards, when the rotating line of the threaded cylinder moves upwards, an annular clamping groove is driven to move upwards, when the annular clamping groove moves upwards, a rubber cylinder is driven to move upwards, when the rubber cylinder moves upwards, the rubber cylinder is extruded by the conical cylinder, then the upper end of the rubber cylinderl shrinks and wraps around the surface of a blocking block, then the conical cylinder is blocked, and erroneous spraying at the conical cylinder position is effectively prevented.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a nozzle mechanical seal structure. Background technique [0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. Spray guns are divided into two types: general pressure type and pressurized type. The spray gun also has a pressure spray gun, a card music spray gun, and an automatic recovery spray gun. [0003] When the existing spray gun is in use, the material is squeezed from the pipe into the nozzle by pressure, and the material is sprayed out through the nozzle, but the pressure mechanism inside the spray gun sometimes checks the solidification pressure due to operational errors, and then the material may be pushed out of the nozzle. Squirted out by mistake. Contents of the invention [0004] The purpose of the present invention is to provide a mechanical sealing structure for the nozzle to solve the problem that the spray gun ...
