Multi-angle internal corner deformed abrasive paper frame and using method thereof

Abstract

The invention discloses a multi-angle internal corner deformed abrasive paper frame. The multi-angle internal corner deformed abrasive paper frame comprises a first bottom plate and a second bottom plate which are connected in a hinged mode; the movable ends of the first bottom plate and the second bottom plate are connected with telescopic plates in a hinged mode; the first bottom plate and the second bottom plate are covered with abrasive paper, and the two ends of the abrasive paper are fixed to the telescopic plates; and the included angle between the first bottom plate and the second bottom plate is adjusted by adjusting the length of the telescopic plates. According to the multi-angle internal corner deformed abrasive paper frame, the purpose of changing the included angle between the first bottom plate and the second bottom plate is achieved by adjusting the length of the telescopic plates, and thus various angular dimensions of grinding work of wall corner putty can be handled;a torque sensor is arranged in a power device, the threshold value of torque is set in a controller, thus when the numerical value of the torque sensor is larger than the threshold value, the controller controls a motor to stop working, in this way, the value of the initial internal corner does not need to be measured, the grinding steps are simplified, and the working efficiency is high; and themulti-angle internal corner deformed abrasive paper frame is simple in structure, small in size, low in weight, easy to use and convenient to operate.

Description

technical field [0001] The invention relates to a multi-angle internal angle deformed sandpaper holder and a use method thereof, which belong to the field of construction tools. Background technique [0002] The wall corner is an important part in the wall putty grinding. Generally, the external corner can be polished separately on both sides. However, in the case of internal corners, due to the shape, it is easy to appear that the corners are not polished straight, and the sharp corners are not polished properly. In the traditional situation, construction workers will buy corner sandpaper holders to deal with this situation, but most of the corner sandpaper holders on the market are right-angle sandpaper holders, but in various buildings such as pipe corridors, there are still many The non-right-angled internal corners bring a lot of trouble to the construction. Under normal circumstances, a corner sandpaper holder will be customized at an angle. However, when the angle of...

However, in the case of internal corners, due to the relationship between the shape, it is easy to appear that the corners are not polished straight, and the sharp corners are not polished properly.

In the traditional situation, construction personnel will buy corner sandpaper holders to deal with this situation, but most of the corner sandpaper holders on the market are right-angle sandpaper holders, but in various buildings such as pipe corridors, there are still many The non-right-angled internal corner brings a lot of trouble to the construction. Under normal circumstances, a corner sandpaper holder will be customized at an angle. However, when the angle of the corner changes in the next operation, the customized sandpaper holder will be useless. To a certain extent, it caused waste and increased the complexity of the operation
