Description

Technical Field

[0001] This utility model relates to the field of sandpaper technology, specifically to a type of abrasive sandpaper with high flexibility. Background Technology

[0002] Sandpaper is a material used for grinding. Depending on the abrasive material, there are various types such as diamond sandpaper, artificial diamond sandpaper, and glass sandpaper. Dry sandpaper is used to polish the surface of wood and bamboo products, while water-resistant sandpaper is used to polish the surface of metal or non-metal workpieces in water or oil. It is commonly known as sandpaper. In actual use, the classification of sandpaper is not very consistent.

[0003] Chinese patent CN212242429U discloses a type of sandpaper with high flexibility. This patent discloses a technical solution with high flexibility, which solves the problem that if the sandpaper has poor flexibility during use, it will break and be damaged, affecting its service life, because the sandpaper will be stretched and bent.

[0004] When in use, the device increases the overall tensile strength of the sandpaper through the fiber layer and reinforcing blocks, and the outer latex paper layer increases the overall softness of the sandpaper. However, the abrasive layer is in direct contact with the outside, which can easily lead to damage to the abrasive layer before use and reduce the sanding effect. Therefore, a more flexible abrasive paper is proposed to solve the above problems. Utility Model Content

[0008] The outer layer is provided with a limiting component to restrict the connecting plate.

[0009] A drive assembly is provided between the two connecting plates to drive the moving plate to move.

[0010] Furthermore, the movable plate and the movable groove are slidably connected, the limiting block and the limiting groove are slidably connected, the connecting plate is an L-shaped plate, and the protective paper is U-shaped.

[0011] Furthermore, the limiting component includes two connecting blocks, which are respectively fixedly connected to the bottom surfaces of two connecting plates. The outer layer has two connecting slots on its front side, and the two connecting blocks extend into the interior of the two connecting slots. Rubber pads are fixedly connected to the left and right sides of the two connecting blocks.

[0012] Furthermore, both the connecting block and the connecting groove are T-shaped, the connecting block and the connecting groove are slidably connected, and the rubber pad is fitted to the connecting groove.

[0013] Furthermore, the drive assembly includes two drive rods, which are movably connected to the interiors of two limiting grooves via bearings.

[0022] 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.

[0023] Please see Figure 1-4 In this embodiment, a type of abrasive paper with high flexibility includes an abrasive paper body 1 and an outer layer 7 and an abrasive layer 8 disposed on the abrasive paper body 1. A protective paper 2 is placed at the bottom of the abrasive paper body 1, and two connecting plates 3 are placed on the top surface of the abrasive paper body 1.

[0024] The bottom surfaces of the two connecting plates 3 are provided with moving grooves 4. The two ends of the protective paper 2 extend into the interior of the two moving grooves 4 respectively. The interior of the two connecting plates 3 is provided with limiting grooves 12. The two ends of the protective paper 2 are fixedly connected with moving plates 14. The side of the two moving plates 14 away from the abrasive paper body 1 is fixedly connected with a limiting block 13 that extends into the limiting groove 12.

[0025] Among them, the movable plate 14 and the movable groove 4 are slidably connected, the limiting block 13 and the limiting groove 12 are slidably connected, the connecting plate 3 is an L-shaped plate, and the protective paper 2 is U-shaped.

[0026] Specifically, the sliding connection between the limiting block 13 and the limiting groove 12 drives the moving plate 14 to move, thereby adjusting the height of the protective paper 2. The abrasive layer 8 enters the interior of the protective paper 2, and the abrasive layer 8 is protected by the protective paper 2.

[0027] In this embodiment, the outer layer 7 is provided with a limiting component, which includes two connecting blocks 9. The two connecting blocks 9 are fixedly connected to the bottom surfaces of the two connecting plates 3 respectively. The front of the outer layer 7 is provided with two connecting grooves 10. The two connecting blocks 9 extend into the interior of the two connecting grooves 10 respectively. Rubber pads 11 are fixedly connected to the left and right sides of the two connecting blocks 9.

[0028] Both the connecting block 9 and the connecting groove 10 are T-shaped, and the connecting block 9 and the connecting groove 10 are slidably connected, with the rubber pad 11 fitting into the connecting groove 10.

[0029] Specifically, the connecting block 9 is pushed so that it is inserted into the connecting groove 10, and then the connecting plate 3 is placed on the outer layer 7. The limiting block 13 is supported by the fit between the rubber pad 11 and the limiting groove 12, thereby improving the stability of the limiting block 13.

[0030] In this embodiment, a drive assembly is provided between the two connecting plates 3. The drive assembly includes two drive rods 5, which are movably connected to the inside of the two limiting grooves 12 via bearings. A screw 15 with one end extending into the inside of the drive rod 5 is fixedly connected to the top surface of each of the two moving plates 14. Two positioning rods 6 are fixedly connected to the top surface of the outer layer 7. Positioning holes 16 are provided on the opposite sides of the two connecting plates 3, and the two positioning rods 6 extend into the inside of the two positioning holes 16 respectively.

[0031] Both drive rods 5 have threaded holes on their bottom surfaces. The screw 15 extends into the threaded holes and is threadedly connected to them. The positioning rod 6 is an L-shaped rod. The positioning rod 6 and the positioning hole 16 are clearance-fitted. The positioning rod 6 is an elastic rod.

[0032] Specifically, rotating the drive rod 5 causes it to rotate. Through the threaded connection between the drive rod 5 and the screw 15, the screw 15 drives the moving plate 14 to move. When the connecting plate 3 moves, it presses against the positioning rod 6, causing the positioning rod 6 to deform. When the positioning rod 6 and the positioning hole 16 are on the same center line, the positioning rod 6 is pulled to reset it. The positioning rod 6 is then inserted into the interior of the positioning hole 16. Through the clearance fit between the positioning rod 6 and the positioning hole 16, the connecting plate 3 is fixed.

[0033] The working principle of the above embodiments is as follows:

[0034] Rotating the drive rod 5 causes it to rotate. Through the threaded connection between the drive rod 5 and the screw 15, and the sliding connection between the limiting block 13 and the limiting groove 12, the screw 15 drives the moving plate 14 to move, thereby adjusting the height of the protective paper 2. This pushes the connecting block 9, causing it to insert into the interior of the connecting groove 10, and then places the connecting plate 3 on the outer layer 7. The connecting plate 3 presses against the positioning rod 6, causing it to deform. When the positioning rod 6 and the positioning hole 16 are on the same center line, pulling the positioning rod 6 resets it, and the positioning rod 6 inserts into the interior of the positioning hole 16. The gap fit between the positioning rod 6 and the positioning hole 16 fixes the connecting plate 3. The fit between the rubber pad 11 and the limiting groove 12 supports the limiting block 13, improving its stability. The abrasive layer 8 enters the interior of the protective paper 2, and the protective paper 2 protects the abrasive layer 8.
