[0007] The wiper strip structure realizes the rapid installation and disassembly of the rubber strip by designing the clamping structure between the mounting plate and the mounting groove at the bottom of the external seat, as well as the clamping cooperation between the clamping plate and the clamping groove. There is no need to remove the entire wiper assembly from the vehicle. The rubber strip can be replaced with a simple operation, which significantly simplifies the disassembly and assembly process. The threaded connection of the fixing bolts further enhances the stability between the mounting plate and the external seat, ensuring the stability and reliability of the wiper during use. At the same time, this design also makes it easy for maintenance personnel to quickly tighten or loosen the strip when necessary. The clamping design of the positioning groove and the positioning plate, as well as the sliding connection of the movable block with the mounting plate through the slide groove, enable the rubber strip to be automatically aligned and fixed during the installation process, greatly reducing the difficulty of disassembly and assembly. The block contacts the anti-slip pad in the fixed groove, which not only enhances the friction between the rubber scraper and the external seat, preventing the wiper from loosening or falling off during use, but also makes the disassembly and assembly process smoother, reducing time cost. By arranging a reset spring on the outside of the movable rod and arranging the damping rod and baffle in the inside of the connecting plate, the utility model realizes effective limiting and buffering of the movable block and the arc-shaped fixed block. The reset spring can provide restoring force when the rubber scraper is subjected to external force, ensuring that the scraper always remains in the correct position, while reducing wear and deformation caused by long-term use. The use of the damping rod and baffle further enhances the stability of the structure, prevents the movable block from excessive movement or shaking during sliding, thereby extending the service life of the wiper.

When the installation is completed, the return spring 17 maintains the close contact between the arc-shaped fixing block 18 and the anti-slip pad 11 under the action of elastic force, ensuring the stable installation of the rubber scraper 4 and its reliability in long-term use.

[0022] In summary: the wiper strip structure realizes the rapid installation and disassembly of the rubber scraper strip 4 by designing the clamping structure between the mounting plate 3 and the mounting groove 2 at the bottom of the external seat 1, and the clamping cooperation between the clamping plate 6 and the clamping groove 5. There is no need to remove the entire wiper assembly from the vehicle. The rubber scraper strip 4 can be replaced with a simple operation, which significantly simplifies the disassembly and assembly process. The threaded connection of the fixing bolts 7 further enhances the stability between the mounting plate 3 and the external seat 1, ensuring the stability and reliability of the wiper during use. At the same time, this design also makes it convenient for maintenance personnel to quickly tighten or loosen the operation when necessary. The clamping design of the positioning groove 8 and the positioning plate 9, and the sliding connection of the movable block 14 with the mounting plate 3 through the slide groove 13, enable the rubber scraper strip 4 to be automatically aligned and fixed during the installation process, which greatly reduces the difficulty of disassembly and assembly. The contact of the anti-slip pad 11 in the fixing groove 10 not only enhances the friction between the rubber scraper 4 and the external seat 1, preventing the wiper from loosening or falling off during use, but also makes the disassembly and assembly process smoother, reducing time cost. By arranging a reset spring 17 on the outside of the movable rod 16 and arranging the damping rod 21 and the baffle 22 inside the connecting plate 15, the utility model realizes the effective limiting and buffering effect of the movable block 14 and the arc-shaped fixed block 18.
