Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a strap-type spraying equipment. Background Technology

[0002] Traditional spraying equipment requires handheld operation or placement on the ground, making it inconvenient to move, especially during high-altitude operations such as spraying building exteriors and steel structures. Operators need to frequently adjust the equipment's position, resulting in low efficiency and safety hazards. Existing backpack-style equipment often suffers from unstable mounting, inconvenient disassembly, or insufficient load-bearing capacity.

[0003] To address the aforementioned technical issues, a backpack-type spraying device is urgently needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a shoulder strap spraying device, including a spraying device body, a connecting hose and a spray gun, wherein the spraying device body is connected to the spray gun through the connecting hose, and the connecting hose serves as a flow pipe for the paint, characterized in that: a double shoulder strap is installed on the rear side of the spraying device body, the top end of the double shoulder strap is locked to the top end of the spraying device body by a buckle assembly, and its bottom end is detachably connected to the bottom end of the spraying device body by a locking ring.

[0005] Furthermore, the buckle assembly includes a buckle, and the top rear side of the spraying equipment body is provided with a snap-fit ​​hole that cooperates with the buckle.

[0006] Furthermore, a connection hole is provided on the rear side of the main body of the spraying equipment, and the bottom end of the locking ring is fastened to the crossbar inside the connection hole.

[0007] Furthermore, the spray gun is a high-pressure spray gun.

[0008] Furthermore, a handle is provided at the top of the main body of the spraying equipment.

[0009] The advantages of the utility model compared to the prior art are:

[0010] The main body of the spraying equipment in this invention has the advantage of large capacity, which can meet the needs of long-term operation. The use of double shoulder straps can distribute the weight of the spraying equipment, reduce operator fatigue, and allow the hands to climb freely or be used for auxiliary fixation. The structure of the double shoulder straps makes it convenient for the operator to carry the spraying equipment on their back for high-altitude operations.

[0011] This utility model uses a structure such as buckles and locking rings to connect the double shoulder straps to the main body of the spraying equipment. The buckle design makes it easy to remove the equipment in an emergency, thus improving safety. Attached Figure Description
