Description

Technical Field

[0001] This utility model belongs to the field of sandpaper technology, specifically relating to a waterproof and wear-resistant sandpaper. Background Technology

[0002] Depending on the abrasive material, there are various types of sandpaper, including diamond sandpaper, synthetic diamond sandpaper, and glass sandpaper. Dry sandpaper (wood sandpaper) is used to polish the surfaces of wood and bamboo. Water-resistant sandpaper (wet sandpaper) is used to polish the surfaces of metal or non-metal workpieces in water or oil; it is commonly known as sandpaper. It is a material used for grinding. It is used to grind the surfaces of metals, wood, etc., to make them smooth and glossy. It is usually made by attaching various abrasive grains to a base paper. Depending on the abrasive material, there are various types of sandpaper, including diamond sandpaper, synthetic diamond sandpaper, and glass sandpaper. Dry sandpaper (wood sandpaper) is used to polish the surfaces of wood and bamboo. Water-resistant sandpaper (wet sandpaper) is used to polish the surfaces of metal or non-metal workpieces in water or oil. The base paper is made entirely from unbleached sulfate wood pulp, resulting in a strong, tough, wear-resistant, and fold-resistant paper with good water resistance. Abrasive materials such as glass sandpaper are bonded to the base paper with adhesives such as resin, and then dried. In actual use, the classification of sandpaper is not very standardized. Currently, due to its simple structure, sandpaper is easily soaked in water during use, which affects its sanding performance and reduces its effectiveness. Therefore, there is a need for a waterproof and wear-resistant sandpaper. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides the following technical solution: a waterproof and wear-resistant sandpaper, comprising a fixing plate 1, a fixing block 2 fixedly installed on the top of the fixing plate 1, a locking threaded rod 3 provided on the surface of the fixing block 2, a locking pressure block 4 fixedly connected to one end of the locking threaded rod 3, a rubber anti-slip block 8 fixedly installed on the bottom of the fixing plate 1, a sandpaper body 5 provided on the lower surface of the fixing plate 1, a wear-resistant layer 6 bonded to one side of the sandpaper body 5, a waterproof layer 7 bonded to the inner wall of the sandpaper body 5, an mounting plate 9 provided on the upper surface of the fixing plate 1, a locking bolt 10 threadedly connected to the surface of the mounting plate 9, and a portable handle 11 fixedly installed on the upper surface of the mounting plate 9.

[0022] The worker places the sandpaper body 5 at the bottom of the fixing plate 1, ensuring it adheres to the rubber anti-slip block 8. Then, the worker places both sides of the sandpaper body 5 into the L-shaped fixing blocks 2. By rotating the locking threaded rod 3, the worker moves the locking pressure block 4, causing it to contact the sandpaper body 5 and apply pressure, thus fixing both sides of the sandpaper body 5. This ensures the stability and accuracy of the sandpaper body 5 during use. The anti-slip sleeve at the bottom of the locking pressure block 4 provides anti-slip protection for the fixed sandpaper body 5, ensuring its stability during use. The rubber anti-slip block 8, due to its contact with the sandpaper body 5, provides excellent anti-slip protection. After installation, the worker can remove the sandpaper body 5 using the portable handle 11 for use on items. During the sanding process, the sandpaper body 5 is protected by a waterproof layer 7 composed of a resin adhesive layer 701 and a brown corundum layer 702. This waterproof layer provides excellent water resistance, allowing water to flow out when the sandpaper body 5 is used with water, preventing it from getting wet and reducing the amount of sandpaper dust produced. The wear-resistant layer 6, composed of a synthetic resin layer 601 and a silicon carbide abrasive layer 602, provides advantages such as anti-clogging, anti-static properties, good flexibility, and high wear resistance, enhancing the wear resistance and ensuring the sandpaper body 5's performance. The angled top handle 11 facilitates user access and improves comfort. Anti-slip grooves 12 enhance stability when using the handle 11.

[0023] In one aspect of this embodiment, the anti-slip sleeve at the bottom of the locking block 4 can provide anti-slip protection for the sandpaper body 5 that is pressed and fixed, ensuring the stability of the sandpaper body 5 during use.

[0024] In one aspect of this embodiment, the two L-shaped fixing blocks 2 are used to clamp and fix the two sides of the sandpaper body 5, and to install and fix the sandpaper body 5 in use, so as to facilitate the installation and use of the sandpaper body 5.

[0025] In one aspect of this embodiment, the waterproof layer 7, composed of a resin adhesive layer 701 and a brown corundum layer 702, gives the sandpaper body 5 a good waterproof effect. When the sandpaper body 5 is used with water, the water will flow out with the sandpaper body 5, preventing the sandpaper body 5 from getting wet and also making the sandpaper body 5 produce smaller dust particles.

[0026] In one aspect of this embodiment, the wear-resistant layer 6, composed of a synthetic resin layer 601 and a silicon carbide abrasive layer 602, can give the sandpaper body 5 advantages such as anti-clogging, anti-static, good softness, and high wear resistance, thereby improving the wear resistance of the sandpaper body 5 and ensuring the effectiveness of the sandpaper body 5.

[0027] In one aspect of this embodiment, the portable grip 11 with an inclined top facilitates the user's use of the sandpaper body 5, makes it easy for the user to pick up and use the portable grip 11, and improves the user's comfort when using the sandpaper body 5. The anti-slip groove 12 is used to improve the stability of the user when using the portable grip 11.

[0028] In one aspect of this embodiment, after the worker loosens the locking bolt 10 on the mounting plate 9, the worker can remove the mounting plate 9 from the fixing plate 1. Conversely, the worker can install the mounting plate 9 onto the fixing plate 1 by tightening the locking bolt 10, thereby facilitating the installation and removal of the portable grip 11 and making it convenient for the user to use the sandpaper body 5.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
