Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a sandblasting structure which is easy to maintain. Background Art

[0002] The sandblasting machine uses compressed air to transport powdered particles (1 to 4 mm in diameter) from one place to another in a pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, thereby improving the surface quality of the object. The sandblasting machine uses a sandblasting head for sandblasting. The sandblasting head generally includes an outer shell, a sandblasting mechanism, a sandblasting ring and a sandblasting disc.

[0003] In the prior art, the sandblasting disc is fixed on the sandblasting ring by a plurality of fastening bolts. This means that when the sandblasting mechanism in the outer shell needs to be maintained, the plurality of fastening bolts need to be loosened in sequence to remove the sandblasting disc from the sandblasting ring. Frequent tightening of the fastening bolts can easily cause the fastening bolts and the screw holes to slip, resulting in an unstable installation, and even the sandblasting disc and the sandblasting ring may be scrapped. In response to this, we propose a sandblasting structure that is easy to maintain to solve the above-mentioned problems. Utility Model Content
