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...

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1 to Figure 6 As shown, a kind of multi-angle internal angle deformed sandpaper frame of the present invention comprises the first base plate 1 and the second base plate of hinged connection, the first base plate 1 and the second base plate are the rectangular plate of 13cm*20cm, between two base plates Punch holes on both sides, one removes 14cm in the middle of both sides, removes 14cm in the middle of the other side, removes 40cm at both ends of the other side, and perforates with pin 5 in between. When the first bottom plate 1 and the second bottom plate are rotating There will be no interference. The movable end of the first bottom plate 1 and the second bottom plate is hingedly connected with a telescopic plate 3, and the telescopic plate 3 and the two bottom plates are hinged through the holes of the pin 5, and the part of the hinged part...
