Double-layer glass trepanning device

Abstract

The invention provides a double-layer glass trepanning device. A trepanning device body is included and is in a barrel shape. A drill handle is arranged on the top of the trepanning device body. The bottom of the trepanning device body is provided with diamond grinding blocks evenly distributed at intervals in the circumference direction of the trepanning device body. A suction cup is arranged inthe trepanning device body. The adsorption face of the suction cup deviates away from the drill handle. The center of the face, towards the drill handle, of the suction cup is provided with a centering rod. The drill handle is provided with a sliding hole communicating with an inner cavity of the trepanning device body. The centering rod and the sliding hole circumferentially rotate and are in sliding fit in the axial direction. The double-layer glass trepanning device has the advantages that during double-layer glass trepanning, the situation that after head-layer glass trepanning is finished, middle glass leftovers fall into the part between double-layer glass and is hard to take out is avoided.

Description

technical field [0001] The invention relates to the field of opening equipment for architectural glass, in particular to a double-layer glass opening device. Background technique [0002] In construction engineering, double-layer glass has the advantage of good heat and sound insulation, but whether it is single-layer glass or bed glass, it is inevitable to encounter occasions where holes need to be made on the glass. The current glass hole opener is used for single-layer glass. It is often not a big problem to open the first layer of glass. After the opening is completed, the glass scraps at the center of the hole can be discharged from the other side smoothly; When the glass waste in the middle falls between the two layers of glass, it will be extremely difficult to remove the waste that falls between the double-layer glass because the double-glazed doors and windows are in the installed state. It is necessary to upgrade the existing glass hole opener aiming at the defici...
