Nut assembly sliding gun structure

This creation is related to a structure of a nut assembly sliding slide, especially a design of a nozzle structure that can adjust a large flow.

Pressed, the air pressure spray gun used for cleaning or painting the surface of the object is connected to a gas pressure source and a liquid source respectively, and one of the liquid sources is extracted by using the Venturi effect generated by the gas pressure input into the air pressure spray gun. The liquid is operated and one of the air pressure lances is pressed to press the handle to adjust the gas pressure to eject the liquid. Alternatively, the liquid source may be connected as a general air pressure lance without using the liquid source, and the gas ejected at a high pressure may be used for drying or dust removal. Generally, when used as a jet, the operation is to control the amount of the jet using the pressing handle. However, in actual operation as a liquid discharge, since the gas pressure output from the air pressure source is a fixed value, the operator must more carefully control the downward pressure applied to the pressing handle to accurately control the flow rate when the liquid is ejected. And the jet force, otherwise there may be a situation in which the pressure is insufficient to cause the liquid to be sucked or the pressure is too high to generate a backflow, which is quite inconvenient for the operator, so it is necessary to improve. Therefore, how to solve the above problems and shortcomings in the past is the direction for the relevant manufacturers engaged in this industry to research and improve. In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

That is, the main purpose of the present invention is to provide a structure of a spray gun assembly with a nut assembly; the problem to be solved is that the operator must more carefully control the downward pressure applied to the pressing handle to accurately control The flow rate and the jet force when the liquid is ejected, otherwise there may be a pressure shortage that causes the liquid to be sucked or the pressure to be excessively high. Environment, it is quite inconvenient for the operator to make a breakthrough; the technical feature of solving the problem is mainly by including a spray gun, which is constituted by a gun body and a flow knob, wherein the The bottom of the gun body is provided with an air inlet end, and one side of the gun body is provided with a pressing handle, and the horizontal extension position of the gun body is provided with a socket, and the air seat of the same is connected to the air inlet end. a guide hole having a threaded section is disposed at a predetermined position of the top surface of the socket; and the bottom end of the flow knob is provided with a stud, and the stud is screwed into the guide hole, so that the flow knob is The outlet flow of the spray gun can be rotated, and one end of the joint is axially connected with an outlet end; a gas pipe body is connected at one end of the spray gun to the outlet end, and the other end is provided with an active end. a detachable stop member; a fixed nut having a stencil-shaped open end shape at one end, and an inner threaded portion of the inner end of the fixed nut, and a central hole through the other end of the fixed nut The middle hole is provided for the gas pipe body to be pierced and blocked by the gas pipe a blocking member, a ring chamber is formed on the ring side between the middle hole and the female thread portion, and a blocking surface is disposed on one side of the ring chamber, and the ring chamber is provided with a rubber gasket and The one side of the washer is positioned to be positioned on the stop surface; thereby, the innovative and unique design enables the spray gun of the present invention to be operated by a single hand-held operation while using a flow knob provided at the upper end of the horizontal joint. The hand adjusts the flow knob to improve the convenience of the hand-held adjustment. Further, the fixed nut of the nozzle can be fixed to the air tube body by elastic rotation, and the top of the central shaft column is fixed when fixed. The edge is forced to deform by the gasket. After the deformation, the gasket radially presses the gas pipe body to achieve the state in which the nozzle is fixed to the gas pipe body.
