Description

Technical Field

[0001] The utility model relates to a buckle connector, in particular to a buckle gas tank anti-falling connector on a spray gun, belonging to the technical field of flame spray guns. Background Art

[0002] Flamethrowers usually use a mixture of fuel (such as propane, etc.) and oxygen to generate flames, and then spray the flames out through the torch structure. Flamethrowers are generally used in some specific operating scenarios, such as local heating before welding in some industrial processes, metal surface treatment, etc.; in outdoor expeditions, they may also be used for ignition in emergency situations.

[0003] The existing connectors usually have a snap-on that is restricted by the notch when inserted into the annular notch to prevent the gas cylinder from falling off the spray gun. However, the traditional connectors are too bulky, which may cause the gas cylinder and the spray gun to be installed loosely. In addition, long-term use may cause the connector to be in a high temperature state, which in turn causes the surface of the connector to have a high temperature, which may cause the user to be burned when operating or touching it, thereby greatly reducing the safety of the snap-on connector on the spray gun to prevent the gas cylinder from falling off.

[0004] Therefore, it is urgent to improve the anti-falling connector of the snap-on gas tank on the spray gun to solve the above-mentioned problems. Utility Model Content
