When welding the connection between the quartz tube and the transverse plate of the quartz boat, in order to make the connection between the transverse plate and the quartz tube heated evenly, it is necessary to move the welding head in a circular shape along the connection between the transverse plate and the quartz tube in a large range, quickly and continuously, which is inconvenient to operate. Utility Model Content

[0005] The utility model aims to provide a welding gun for bonding quartz tubes, thereby solving the technical problem that the existing welding guns are of conventional structural form and have no targeted welding.

[0007] A welding gun for bonding quartz tubes comprises a mounting handle, a connecting block is fixedly mounted on the upper end of the mounting handle, a hydrogen inlet pipeline and an oxygen inlet pipeline are arranged inside the mounting handle and the connecting block, a mixing tube is connected to the upper end of the connecting block, a U-shaped jet tube is connected to the upper end of the mixing tube through the connecting tube, and first nozzles for bonding quartz boat plate surfaces are connected to both sides of the upper end of the U-shaped jet tube.

[0008] As a further solution of the utility model, the flame spraying directions of the two first nozzles are arranged to face each other.

[0009] As a further solution of the utility model, the axes of the two nozzles are on the same straight line.

[0010] As a further solution of the utility model, the bottom of the mounting handle is respectively connected with a hydrogen inlet nozzle and an oxygen inlet nozzle, the hydrogen inlet nozzle is connected with the hydrogen inlet pipeline, and the oxygen inlet nozzle is connected with the oxygen inlet pipeline.

[0011] As a further solution of the utility model, a hydrogen regulating valve for regulating the amount of hydrogen entering the mixing tube is installed on the connecting block, and an oxygen regulating valve for controlling the amount of oxygen entering the mixing tube is provided at the lower end of the mixing tube.

[0012] Compared with the prior art, the welding gun for bonding quartz tubes of the utility model has the following beneficial effects:

[0013] The utility model can heat both sides of the connection between the quartz tube and the horizontal plate on the quartz boat at the same time by means of two nozzles arranged opposite to each other, and it is only necessary to control the nozzle to move up and down without driving the nozzle to move along the annular direction of the quartz tube, thereby effectively improving the welding efficiency and being simple to operate.
