[0018] The utility model will be described in detail in combination with the drawings and examples.
[0019] A kind of antiskid sand cloth, such as Figure 1 And Figure 2As shown, it comprises a sand layer 1, and a reinforcing layer 2 is detachably connected to the side of the sand layer 1 away from the sanding surface. The detachable arrangement facilitates the replacement of the sand layer 1, improving the practicality. The reinforcing layer 2 is made of hard plastic, and the hardness of the reinforcing layer 2 is higher than that of the sand layer 1, so that the sand layer 1 is higher and more flat in hardness, thereby saving labor in the process of applying force to the sand layer 1. At the same time, the hard plastic is light in weight while ensuring the hardness, reducing the influence of the additional reinforcing layer 2 on the normal sanding process of the sand layer 1. The side of the reinforcing layer 2 away from the sand layer 1 is fixedly connected with a plurality of anti-skid sleeves 3 with an opening. The plurality of anti-skid sleeves 3 are arranged in a staggered manner on the reinforcing layer 2. The side of the reinforcing layer 2 away from the sand layer 1 is fixedly connected with a plurality of rubber strips 8. The plurality of rubber strips 8 are fixedly connected at the opening positions of the plurality of anti-skid sleeves 3, respectively. The top surface of the rubber strip 8 is provided with a placing groove. One end of the anti-skid sleeve 3 is open, and the other end is fixedly connected to the reinforcing layer 2. The inner wall of the anti-skid sleeve 3 close to the closed end can also be bonded or filled with some soft materials such as cotton and sponge to protect the fingers. The rubber strip 8 has a larger friction force when it comes into contact with the fingers. The placing groove on the rubber strip 8 increases the contact area between the rubber strip 8 and the fingers. When the fingers are inserted into the anti-skid sleeve 3, the first joint of the fingers is located at the position of the placing groove. When the fingers drive the reinforcing layer 2 to slide, it will be more in line with the hand. The staggered arrangement of the anti-skid sleeves 3 is also to better adapt to fingers of different lengths, making people more comfortable and safe when using the sand cloth.
[0020] As shown in Figure 1 and Figure 2 , the fingers are inserted into the anti-skid sleeve 3 from the open end of the anti-skid sleeve 3. The closed end of the anti-skid sleeve 3 can block the further forward sliding of the fingers. The rubber strip 8 at the opening of the anti-skid sleeve 3 increases the friction force between the reinforcing layer 2 and the fingers, making it more laborious for the fingers to press on the reinforcing layer 2 and slide backward along the surface of the reinforcing layer 2. The hand can more easily drive the movement of the reinforcing layer 2 when moving, and the reinforcing layer 2 drives the sand layer 1 to polish the object.
[0021] As shown in Figures 1-3As shown, a plurality of anti-skid sleeves 3 are provided on the reinforcing layer 2, and a plurality of through grooves 7 corresponding to the anti-skid sleeves 3 are provided on the reinforcing layer 2. The reinforcing layer 2 is provided with a receiving cavity 4 penetrating the side wall of the reinforcing layer 2 on both sides. The receiving cavity 4 is provided with an electrostatic generating assembly. Part of the electrostatic generating assembly is exposed in the through groove 7. The electrostatic generating assembly includes a plurality of chemical yarns 5 and a fur piece 6. When the finger is inserted into the anti-skid sleeve 3 and contacts the chemical yarn 5 through the through groove 7, the chemical yarn 5 is slightly rubbed in the through groove 7. The chemical yarn 5 contacts and rubs the fur piece 6. Since the moisture content in the chemical yarn 5 is low, static electricity is more likely to be generated after contacting the fur piece 6. Static electricity can attract light fluff or impurities around. Since the sand layer 1 mainly performs polishing work, relatively heavy debris will fall under the action of gravity, and light debris will be scattered in the air, which may fall into the eyes. The generated static electricity can adsorb the light debris to reduce the range of debris dispersion and improve the safety of the sand cloth.
[0022] As shown in Figure 2 and Figure 3 , the two ends of the chemical yarn 5 are fixedly connected to the inner top surface of the receiving cavity 4 close to the side wall. The chemical yarn 5 is preferably polyester yarn or nylon yarn. The two ends of the chemical yarn 5 are fixed. Since the chemical fiber has good elasticity, the finger can press on the chemical yarn 5 through the through groove 7. The chemical yarn 5 deforms and inserts into the fur piece 6. The fur piece 6 is fixedly connected to the inner bottom surface of the receiving cavity 4 corresponding to the position of the chemical yarn 5. The two ends of the chemical yarn 5 are flush with the two side walls of the reinforcing layer 2 corresponding to the reinforcing layer 2. The diameter of the chemical yarn 5 is greater than half the height of the receiving cavity 4 and less than the height of the receiving cavity 4. The deformation of the chemical yarn 5 provides space. The contact area between the chemical yarn 5 and the fur piece 6 is increased after the deformation of the chemical yarn 5. Therefore, when the finger presses the chemical yarn 5 and drives it to rotate, static electricity can be generated faster to adsorb the fluff generated during polishing.
[0023] As shown in Figure 3 , a clamping groove 9 is provided on one side wall of the reinforcing layer 2. The clamping groove 9 is provided as a tapered groove. The inner wall of the clamping groove 9 is fixedly connected with a buffer piece. When the finger is fixed on the reinforcing layer 2, the thumb is fixed in the clamping groove 9. The clamping groove 9 further increases the connection strength between the hand and the reinforcing layer 2, ensuring that the movement of the finger can stably drive the movement of the reinforcing layer 2. The buffer piece makes the inner wall of the clamping groove 9 softer, reducing the damage to the finger during use.
[0024] Working principle: sand layer 1 is bonded to one side of the reinforced layer 2 plane, the thumb is fixed in the clamping groove 9, the remaining four fingers are respectively inserted into the four anti-skid sleeve 3, and the first knuckle of the four fingers is clamped in the position of the rubber strip 8, further limiting the sliding of the fingers, the finger pulp is pressed on the chemical yarn 5 through the through slot 7, with the movement of the fingers to drive the chemical yarn 5 to rub in the fur piece 6, so that the chemical yarn 5 generates static electricity to adsorb the small particles generated by polishing, the small particles enter into the containing cavity 4 along the gap, and the containing cavity 4 can be cleaned by water washing after a period of use when the particles in the containing cavity 4 are accumulated too much, so that the sand cloth can be reused.
[0025] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application can also be considered as the protection scope of the present application.
