[0026] Example 1: as Figures 1-8The utility model provides a kind of tear-resistant seat dust cover, including, first dust cover 1, the bottom of first dust cover 1 is close to four corner parts and is evenly provided with moving assembly 2, four moving assembly 2 all include fixed plate 201, the outer surface of four fixed plate 201 is all set with sliding slot 202, the inner wall of four sliding slot 202 is all slidingly connected with first slider 203, the inner wall of four first slider 203 is all set spring 204, one end of four spring 204 is all fixedly connected with slide shaft 205, one end of four slide shaft 205 is all fixedly connected with connecting plate 206, the outer surface of four connecting plate 206 is close to two side edges and is all fixedly connected with moving shaft 207, the outer surface of four first slider 203 is all fixedly connected with first moving block 208, the other end of four spring 204 is respectively fixedly connected with the inner wall of four first slider 203, the outer surface of four slide shaft 205 is respectively slidingly connected with the inner wall of four first slider 203, the outer surface of four fixed plate 201 is respectively slidingly connected with the outer surface of four first moving block 208, the outer surface of four fixed plate 201 is all set with multiple evenly arranged circular groove 209, the bottom of first dust cover 1 is close to four corner parts and is all set with recess 3, the inner wall of four recess 3 is all provided with slide rail 4, the inner wall of four slide rail 4 is all slidingly connected with second slider 5, the outer surface of four second slider 5 is all fixedly connected with second moving block 6.

[0027] The effect achieved by the whole embodiment 1 is that when the anti-tear seat dust cover is used, the first dust cover 1 and the second dust cover 7 are both made of nylon material, which has high strength and wear resistance, and is very suitable for dust covers that need to be moved and rubbed frequently. The nylon material is a known technology and will not be described in detail. When the first dust cover 1 needs to be attached to the surface of the seat, the first dust cover 1 can be laid flat on the seat, and the second moving block 6 is moved to adapt to the size of the seat surface. The second moving block 6 will move with the second sliding block 5, and the second sliding block 5 will slide along the inside of the slide rail 4. Since the slide rail 4 is a trapezoidal groove, it can ensure that the outer surface of the second sliding block 5 can stably slide along the inside of the slide rail 4. When the second sliding block 5 is slid to the appropriate position, the second moving block 6 is at the corner of the surface of the seat at this time, and the first dust cover 1 is evenly attached to the surface of the seat. Then move the connecting plate 206, move the connecting plate 206 away from the fixed plate 201, and the connecting plate 206 will drive the two moving shafts 207 away from the circular groove 209 while driving the sliding shaft 205 to move. The sliding shaft 205 slides along the inner wall of the first sliding block 203 while stretching the spring 204. When the moving shaft 207 is completely away from the circular groove 209, the connecting plate 206 is moved vertically, and the connecting plate 206 drives the sliding shaft 205 and the moving shaft 207 to move vertically. The sliding shaft 205 drives the first sliding block 203 to move vertically, and the outer surface of the first sliding block 203 slides along the inner wall of the slide groove 202. At the same time, the first sliding block 203 drives the first moving block 208 to move, until the outer surface of the first moving block 208 is attached to the bottom of the seat, and then the first sliding block 203 stops sliding. Then the worker releases the connecting plate 206, and the stretching force of the spring 204 disappears. The stretching force of the spring 204 itself drives the sliding shaft 205 to slide to the inner wall of the first sliding block 203. The first sliding block 203 drives the connecting plate 206 to move, and the connecting plate 206 drives the moving shaft 207 to move. The outer surface of the moving shaft 207 slowly slides into the inner wall of the circular groove 209. At this time, the first moving block 208 and the second moving block 6 clamp the seat, and when the first dust cover 1 is attached to the outer surface of the seat, the moving shaft 207 is moved, and the moving shaft 207 is in contact with the circular groove 209, so that the first dust cover 1 is fixed on the seat. The problem of the dust cover sliding on the surface of the seat when the dust cover is not attached to the seat, forming excessive tension in some parts and increasing the risk of tearing the dust cover is solved.

[0028] Embodiment 2: as Figures 1-8As shown, the outer surfaces of the four second moving blocks 6 are respectively in sliding contact with the outer surfaces of the four fixed plates 201, the bottom of the first dust cover 1 is fixedly connected with the second dust cover 7 near the edge, the outer surfaces of the four fixed plates 201 are all fixedly connected with the inner wall of the second dust cover 7, the bottom of the second dust cover 7 is fixedly connected with the first fixed block 8 on both sides, and the bottom of the second dust cover 7 is fixedly connected with the second fixed block 9 on the other two sides.

[0029] The effect achieved by the whole embodiment 2 is that when the anti-tearing seat dust cover is used, first, the first dust cover 1 and the second dust cover 7 need to be unfolded, the inside of the second dust cover 7 is sleeved on the outer surface of the seat, and then the outer surface of the first dust cover 1 is in contact with the seat. At this time, since the bottom of the second dust cover 7 is fixedly connected with the symmetrical first fixed block 8 and the second fixed block 9, the gravity of the first fixed block 8 and the second fixed block 9 will drive the four sides of the second dust cover 7 to move downward uniformly, the four sides of the second dust cover 7 will drive the four sides of the first dust cover 1 to generate uniform downward force, the outer surface of the first dust cover 1 is in contact with the seat, the four sides of the second dust cover 7 drive the four sides of the first dust cover 1 to generate uniform downward force, thereby driving the outer surface of the first dust cover 1 to be evenly laid on the seat, thereby reducing the time of the staff to evenly wrap the first dust cover 1 on the surface of the seat, and ensuring the simple and efficient use of the anti-tearing seat dust cover.

[0030] Working principle: an anti-tear seat dust cover in use, the staff first need to contact the first dust cover 1 with the outer surface of the seat, at this time the first fixed block 8 and the second fixed block 9 of the gravity of the second dust cover 7 will be brought around evenly down, the second dust cover 7 will bring the first dust cover 1 around the four uniform downward force to bring the first dust cover 1 evenly on the seat, then move the second moving block 6, the second moving block 6 will be brought to the second sliding block 5 along the inside of the slide rail 4, when the second moving block 6 is in the appropriate position on the seat, stop moving, move the connecting plate 206, the connecting plate 206 will be moved away from the fixed plate 201, the connecting plate 206 will be brought to move the shaft 207 and the slide shaft 205, the slide shaft 205 will produce stretching to the spring 204 when moving, then move the connecting plate 206 vertically, the connecting plate 206 will be brought to move the slide shaft 205 and the moving shaft 207 vertically, the slide shaft 205 will be brought to move the first sliding block 203 vertically, the first sliding block 203 will be brought to move the first moving block 208, until the outer surface of the first moving block 208 is in contact with the bottom of the seat, stop sliding the first sliding block 203, then the staff releases the connecting plate 206, the stretching force of the spring 204 will be brought to slide the slide shaft 205 to the inner wall of the first sliding block 203, the first sliding block 203 will be brought to move the connecting plate 206, the connecting plate 206 will be brought to move the moving shaft 207, until the outer surface of the moving shaft 207 is in contact with the inner wall of the circular groove 209, when the first dust cover 1 is in contact with the outer surface of the seat, the seat is clamped by the first moving block 208 and the second moving block 6, and the moving shaft 207 is moved to contact the circular groove 209, so that the first dust cover 1 can be fixed on the seat, solving the problem that when the dust cover does not fit the seat, the dust cover will slide on the surface of the seat, forming excessive tension in some parts, increasing the risk of tearing the dust cover.
