Description

Technical Field

[0001] The utility model relates to the technical field of glue injection equipment, in particular to a general-purpose double multi-tube glue injection gun. Background Technique

[0002] During the aircraft manufacturing process, the sealant used is usually composed of a variety of base materials mixed in proportion. To facilitate the management of the mixing ratio, many manufacturers make the base materials into the form of different thicknesses of glue tubes in combination. When in use, all the glue tubes need to be pressed at the same distance simultaneously to achieve the required mixing ratio. Therefore, it is necessary to carry out production and manufacturing operations through a glue injection gun.

[0003] However, when the existing glue injection gun is in use, it can only perform glue injection operations on a single sealant. The convenience of injecting sealants with different base materials through a set of glue injection guns is not high, which reduces the efficiency of completing all work with the same glue injection gun, resulting in problems such as increased production costs, increased difficulty in tool management, and increased maintenance costs.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a general-purpose double multi-tube glue injection gun is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a general-purpose double multi-tube glue injection gun to solve the problem of low convenience of injecting sealants with different base materials through a set of glue injection guns as mentioned in the above background technique.

[0026] Working principle: When using the general double multi-tube glue gun, first, the hose is installed on the glue gun through the clamping device 1, which can adapt to sealant hoses of different sizes and different numbers of hoses, and the installation is firm and not easy to loosen. By adjusting the size and length of the adjustable push rod 2, the number and types of the adapted sealant hoses can be expanded, and it has wide applicability.

[0027] Finally, when pressing the lever handle 7, the lever handle 7 pushes the thick brake block 11 to tilt, clamps the rod part of the second non-replaceable push rod 9, and pushes the piston rod to move forward; when the lever handle 7 is released, the first spring 15 returns the thick brake block 11 to the vertical position, and a gap is generated between the thick brake block 11 and the rod part of the second non-replaceable push rod 9. When the lever handle 7 is released and the stop piece 13 is pressed, the stop piece 13 becomes vertical and a gap is generated between the stop piece 13 and the rod part of the second non-replaceable push rod 9, and the first non-replaceable push rod 4 and the second non-replaceable push rod 9 can be pulled backward, achieving the effect of improving the convenient glue injection of the glue gun.
