A deformable liquefied gas torch

Abstract

The invention discloses a deformable liquefied gas flame gun. The deformable liquefied flame gun comprises a gun rod and spray heads. The spray heads includes a fixed spray head fixed to the end of the gun rod and a movable spray head movably connected with the gun rod. The gun rod is provided with a rotary cylinder and a control mechanism connected with the rotary cylinder, wherein the rotary cylinder is provided with a drive rod, the drive rod is movably connected with an upper track disk push rod through a sliding block, the upper track disk push rod is connected with an upper track disk, a support is arranged at the end of the upper track disk push rod and is parallel to the fixed spray head, the support is connected with the movable spray head through a first connecting rod and a second connecting rod, a lower track disk is fixedly connected to the upper track disk and connected with a lower track disk push rod, and the end of the lower track disk push rod is movably connected with the first connecting rod. The deformable liquefied gas flame gun can have different forms by cooperation of the movable spray head and the fixed spray head so as to complete corresponding work better, and therefore the deformable liquefied gas flame gun has the advantages of being high in working efficiency and practicality.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a liquefied gas spray gun, in particular to a deformable liquefied gas spray gun. Background technique [0002] The liquefied petroleum gas torch is a heating and welding tool fueled by liquefied petroleum gas. It can reach a high temperature of 1300 degrees when used correctly. It has the advantages of low cost, safety and convenience, no pollution, and stable performance. There are also many types of flamethrowers on the market. The common ones are pressure type spray guns, Carol type spray guns, and automatic recovery type spray guns. These flamethrowers are widely used in metal material welding, mechanical parts heating (fire), casting Industry (mud core baking), leak repair roof (melting asphalt), wooden boat repair (drying), meat processing (hair removal), communication cable repair, old paint baking shovel melting, jewelry processing, wood product baking, granite surface Smooth han...

AI Technical Summary

Problems solved by technology

[0003] The liquefied gas spray gun currently on the market is generally composed of a gun shaft and a nozzle fixed at the end of the gun shaft. During use, because the nozzle is fixed, this type of flame gun has poor flexibility and poor practicability during use. Shortcomings

In addition, the nozzle of this liquefied flame gun often forms an air inlet cavity with a gradually increasing cross-sectional area along the air inlet direction, and is connected to the air outlet plate. During use, due to the impact force of the liquefied gas, it is often A small area in the middle of the gas outlet plate is sprayed out, so that only a small area in the middle of the nozzle will have flames, so this kind of liquefied flamethrower still has the disadvantages of low work efficiency and poor practicability
