Description

Technical Field

[0001] This utility model relates to the field of explosive charging technology, and in particular to a handheld plastic explosive charging gun. Background Technology

[0002] With the rapid development of the automotive industry, the demand for disassembling various automotive components is increasing daily. After tire installation and removal, the tires need to be re-inflated. A tire inflator, as a specialized device, helps the tire bead close quickly after installation and before inflation, thus avoiding the problems of excessive time consumption or inability to inflate when using an air gun.

[0003] However, the tire inflators currently on the market have certain structural defects. Their air outlet pipe is integrated with the air cylinder, and the air cylinder must be lifted together during use. This not only increases the labor intensity of the operator, but also, due to the limitation of the flat valve angle, when handling large tires, the operator's hand holding the handle is very likely to come into contact with the tire, thus affecting the accuracy and convenience of operation. Summary of the Invention

[0004] This invention provides a handheld plastic blasting gun to overcome the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A handheld plastic explosive gun includes: a hose, a gas cylinder, and a gun body;

[0007] The gun body includes a gas pipe, a grip, and a flat nozzle. The gas pipe is located on the grip. One end of the gas pipe is connected to a gas cylinder via a hose, and the other end of the gas pipe is connected to the flat nozzle. A push-button switch is provided on the grip, which is used to control the opening and closing of the gas cylinder.

[0008] The flat opening of the flat nozzle is located at the end of the flat nozzle away from the air outlet pipe, and the length direction of the flat opening is parallel to the direction in which the handle extends from the end near the air outlet pipe to the end away from the air outlet pipe.

[0009] Furthermore, it also includes an elbow fixed to the handle, the push-button switch being connected to the elbow, and the push-button switch being connected to a quick-release valve on the gas cylinder via an air tube passing through the elbow and the hose.

[0010] Furthermore, it also includes a connecting sleeve and a spacer sleeved on the connecting sleeve. The connecting sleeve is located between the elbow and the push-button switch. The handle has a receiving cavity and a through hole communicating with the receiving cavity. The receiving cavity can accommodate the elbow, the connecting sleeve, and the spacer sleeve.

[0011] The connecting sleeve has a limiting protrusion on its outer periphery and a threaded hole inside the connecting sleeve. The elbow is threadedly connected to the threaded hole. The push-button switch has a threaded part that passes through the through hole and is threadedly connected to the threaded hole.

[0012] The button switch has an external hexagon on its outer periphery. When the external hexagon is tightened, the limiting protrusion presses the spacer against the inner wall of the receiving cavity.

[0013] Furthermore, the grip includes a housing and a top cover, the housing and the top cover forming the receiving cavity, the through hole being provided on the housing, and the housing and the top cover being connected by screws.

[0014] Furthermore, the end of the air outlet pipe away from the flat nozzle is provided with an external thread, and the hose is threadedly connected to the air outlet pipe.

[0015] Furthermore, it also includes a hanging ring, which is respectively disposed on both sides of the air outlet pipe along with the handle.

[0016] Furthermore, the inner wall of the air outlet pipe is smoothly connected to the inner wall of the flat-mouth air nozzle.

[0017] Furthermore, the grip is provided with a protective ring, and the button switch is located inside the protective ring.

[0018] Furthermore, the retaining ring is provided with a mounting hole, which is coaxially arranged with the push button switch.

[0019] Furthermore, the gun body is made of plastic.

[0020] Beneficial effects: The handheld plastic blasting gun provided by this utility model has an air outlet tube connected to an air cylinder via a flexible hose, which eliminates the need for the operator to lift the air cylinder, thereby reducing the burden on the operator and making the operation more convenient and labor-saving; by making the flat nozzle of the gun body parallel to the handle, the hand will not touch the tire when the flat nozzle is aligned with the tire bead, thus avoiding interference with the operation.
