Wall surface drilling dust prevention device capable of measuring depth and application method thereof

Abstract

The invention discloses a wall surface drilling dust prevention device capable of measuring a depth and an application method thereof. The device mainly comprises a fixed hoop, a connecting ruler, a constant-force spring module and a dustproof cover. A rectangular iron block is welded above the fixed hoop; scales are arranged above the connecting ruler; one end of the connecting ruler is welded with an outer thin-wall ring; two rollers in the constant-force spring module are symmetrically positioned in a module shell; constant-force springs are clamped on the rollers, and are special spiral wire metal sheets; the metal sheets extend out from the module shell, and the end parts are connected with special buckles; and a narrow opening end of the dustproof cover is connected with an inner thin-wall ring; a baffle plate is arranged at the lower part of a wide opening end of the dustproof cover; and a rubber ring is arranged at the upper edge. All modules are assembled on an electric drill in sequence in use; the dustproof cover butts against a wall surface; and after a drilling machine is started, the dustproof cover is tightly bonded on the wall surface in the whole process from drilling to pullout of a drilling rod, so that the scattering and the flyoff of chips and dust are greatly reduced, and meanwhile, the precise drilling depth is guaranteed.

Description

Technical field [0001] The invention relates to a drilling auxiliary tool, in particular to a wall drilling dust-proof device. Background technique [0002] As a commonly used drilling tool in building construction, electric drills are widely used before and after house decoration. In actual wall drilling operations, the rotation of the drill bit will bring a lot of debris and dust, which will be scattered in the air and pollute the environment, affecting the health of the operators. It is not easy to clean up when scattered on the ground and walls, especially for the indoor environment after decoration. The stains and imprints affect the appearance. In order to solve the debris problem during the construction process, many operators often lay waste cardboard, cloth, etc. on the ground, but they still cannot avoid the dust from flying around. Summary of the invention [0003] Aiming at the problems encountered in drilling operations, the present invention provides a depth-measur...

During the actual wall drilling operation, the rotation of the drill bit will bring a lot of debris and dust, which will be scattered in the air to pollute the environment and affect the health of the workers. It is difficult to clean up the scattered on the ground and walls, especially for the indoor environment after decoration. Stains and imprints affect the appearance

During the on-site construction process, many operators often lay waste cardboard, cloth, etc. on the ground in order to solve the problem of debris, but it is still impossible to avoid dust flying around
