Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an exterior wall hole enlarging device with a dust collecting structure. Background Art

[0002] The traditional construction plan for sealing screw holes in exterior walls includes the following steps: base acceptance - manual drilling - depth measurement - acceptance - clean water flushing - waterproof mortar sealing - JS waterproofing application. Traditional manual drilling takes a long time, and the screw holes are prone to not being fully enlarged, resulting in uneven hole sizes and the need to clean the wall casing. Therefore, using an exterior wall hole enlarging device with an electric drill to enlarge the holes can effectively improve the efficiency and effect of hole enlarging. However, the existing exterior wall hole enlarging device still has certain defects during use.

[0003] For example, an electric drill for reaming a hole that can control the drilling depth proposed in application number CN202122758573.9 belongs to the field of electric drill technology, and includes an electric drill body, a fixed block, a movable block, a movable rod, a fastening screw, a movable groove one, a movable groove two, and a gasket. The beneficial effects of this embodiment are as follows: a movable block is provided on the top of the electric drill body, a movable rod is provided inside the movable block, and a scale is provided on the surface of the movable rod. The depth of the drilling is calculated during use, and the distance from the left side of the movable rod to the left end of the drill bit is adjusted according to the scale on the surface of the movable rod, so that the depth of the drilling can be accurately controlled. The movable block and the fixed block are movably connected through a movable groove. When drilling a hole that does not require depth control, the movable block can be removed together with the movable rod to reduce the weight of the electric drill during drilling. A gasket is provided at the bottom of the fastening screw, and the gasket is made of rubber material with an arc-shaped cross-section. It can fix the length of the movable rod by the fastening screw, and can prevent the scale on the surface of the movable rod from being scratched by the bottom of the fastening screw, affecting the accuracy of drilling. In actual use, the reaming electric drill will generate a lot of dust in the process of reaming the exterior wall of the building, and failure to process and collect this dust will affect the surrounding construction environment.

[0004] Therefore, we propose an exterior wall hole enlarging device with a dust collection structure to solve the above problems. Utility Model Content
