The invention discloses a polyurethane foaming agent spraying gun with the adjustable spraying angle. The polyurethane foaming agent spraying gun with the adjustable spraying angle comprises a gun nozzle, a gun pipe, a gun body, an adaptor, a handle and an ejection needle in the gun pipe. A hole is formed in the gun body. Chemical agents with pressure pass the adaptor and enters the gun body through the hole; a trigger capable of controlling ejection of the chemical agents entering the gun body through the gun nozzle is arranged on the gun body; the gun pipe comprises a front pipe body section for installing the gun nozzle and a rear pipe body section connected with the gun body, the front pipe body section and the rear gun body section are connected with a universal joint, and the universal joint is provided with a channel where the ejection needle can penetrate; the ejection needle comprises a front ejection needle section and rear ejection needle section, the front ejection needle and the rear ejection needle are connected through a flexible piece, and the flexible piece is located in the channel of the universal joint. The front pipe body section can rotate relative to the rear pipe body section, when the angle of the front pipe body section is changed, an elastic piece deforms, the front ejection section bends over along with the front pipe body section, and accordingly the ejection angle is adjusted.
Description
technical field [0001] The invention relates to the field of liquid injectors, in particular to a polyurethane foam spray gun. Background technique [0002] The polyurethane foam spray gun includes a nozzle, a barrel, a gun body, an adapter and a handle, and a thimble in the barrel; a hole is provided on the gun body, and the chemical agent with pressure enters the gun body through the hole through the adapter. The trigger that can control the chemical agent entering the gun body and spray out from the gun nozzle. When in use, start the trigger to move the thimble backward, the thimble opens the nozzle, and the chemical agent is sprayed out through the nozzle. After use, the trigger is released, the thimble resets under the action of the compression spring, the gun nozzle is closed, and the chemical agent stops spraying. The shortcoming of this spray gun is: the injection angle of spray gun is fixed, can only spray towards one direction. Contents of the invention [000...
