Description

TECHNICAL FIELD

[0001] The utility model relates to building decoration tool technical field, especially indoor decoration wall surface polishing device. BACKGROUND

[0002] In indoor decoration engineering, wall surface polishing is a very key and frequent basic process, and its polishing effect is directly related to the quality and overall aesthetic degree of subsequent wall decoration (such as painting, pasting wallpaper, etc.).

[0003] Traditional wall surface polishing method is mostly dependent on manual sandpaper or manual polishing with sandpaper frame, and this method is not only inefficient, but also has great labor intensity because of completely relying on manual operation, and long-time operation can easily cause arm soreness and fatigue of the operator, and manual polishing is difficult to guarantee the uniformity of polishing force and angle, which can easily cause uneven wall surface polishing and cause local over-polishing or under-polishing, thereby affecting the final decoration effect.

[0004] With the development of electric tools, some wall surface polishing devices appear on the market, but there are still many deficiencies. Some polishing devices are only provided with a single polishing component, and the reaction force generated between the polishing component and the wall surface during work can directly act on the arm of the operator, so that the operator needs to consume great force to maintain the stability of the device, so as to ensure the normal polishing, which undoubtedly increases the operation difficulty and makes it difficult for the operator to continuously work for a long time.

[0005] In addition, a large amount of dust will inevitably be generated during wall surface polishing, which not only flies everywhere and pollutes the indoor environment, but also is inhaled by the operator, thereby causing serious harm to the health of the operator. Some existing polishing devices lack effective dust collection function or have poor dust collection effect, and cannot timely and completely remove the dust generated during polishing, so that the indoor air is turbid, and the subsequent cleaning work is heavy.

[0006] Moreover, after long-time use of the polishing component, a large amount of dust and other sundries can be easily adhered to the surface of the polishing component, which can greatly reduce the polishing effect of the polishing belt, reduce the polishing efficiency, shorten the service life of the polishing component, increase the use cost, and at the same time, the transmission components in the device, such as gears, pulleys and belts, can also be easily worn, jammed and other problems due to exposure to dust environment, thereby affecting the normal operation and reliability of the whole device.

[0007] In summary, in order to improve the efficiency and quality of wall surface polishing in indoor decoration, reduce the labor intensity of the operator, improve the working environment, prolong the service life of the polishing component and ensure the stable operation, it is particularly urgent to develop a wall surface polishing device for indoor decoration, which can effectively offset the reaction force and has good cleaning and dust collection function.
