Foaming tank mounting adapter for foaming gun

Abstract

The invention discloses a foaming tank mounting adapter for a foaming gun. The foaming tank mounting adapter comprises a mounting frame movably connected to a gun body through a valve element, wherein the mounting frame is used for being connected with a foaming tank; a valve nozzle is connected to the valve element in a sleeving manner, and the upper end of the valve nozzle is matched with a nozzle on the foaming tank; and an actuating structure is arranged between the mounting frame and the valve element, and the mounting frame achieves axial movement of the valve nozzle on the valve element through the actuating structure. A liquid flow channel is formed in the valve element and the valve nozzle, a blocking structure is arranged in the liquid flow channel and located between the valve nozzle and the valve element, and the valve nozzle moving axially enables the blocking structure to be closed to block or open the liquid flow channel so as to achieve communication of the liquid flow channel. The mounting frame achieves the movement of the valve nozzle through the actuating structure, and manual control can be carried out. Particularly, when the foaming tank is detached, the blocking structure can be in a closed state, so that the liquid flow channel is blocked, foaming liquid in a gun barrel is prevented from flowing back to the outer side, and the use cleanliness of the foaming gun is guaranteed.

Description

technical field [0001] The invention relates to a foaming gun, in particular to an adapter on the foaming gun for realizing the installation of a foaming tank. Background technique [0002] Foaming agents are often used in architectural decoration. The foaming agent is mainly used to coat the gaps between plates or other structures. The foaming agent accumulated in the gaps will be sealed in the gaps after expansion and solidification. to achieve the sealing of the gap. When the foaming agent is applied, it is generally realized by means of a foaming gun. The structure of the foaming gun mainly includes a gun body and a gun barrel. The gun barrel is provided with a needle bar, and the gun body has a liquid cavity. The adapter is used to connect with the foaming tank. The adapter has a channel leading to the liquid cavity; There is a trigger on the body, and the trigger is connected with the needle bar. When the trigger is pulled, the needle bar will follow the trigger. A ...

AI Technical Summary

Problems solved by technology

Frequently used foaming guns usually do not have the problem of curing blockage, but in the actual application process, due to various reasons, the foaming gun will be out of service for a long time, and the conical spring immersed in the foaming agent will Solid crystallization occurs, and more solid crystallization will cause the conical spring to lose its activity, which will affect the sealing between the sealing ball and the sealing gasket

When removing the foam tank, since the sealing ball cannot touch the sealing gasket in time, the foaming agent in the gun barrel will flow back from the gap between the sealing ball and the sealing gasket to the outside of the adapter. Backflow liquid for cleaning, which will cause trouble in use
