Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a car wiper bracket connection structure, including a wiper bracket body 1. In order to solve the problem of cumbersome fixing, installation and disassembly of the wiper device, an active cavity 4 is provided in the wiper bracket body 1, a mounting strip 5 is slidably installed in the active cavity 4, a locking mechanism 2 is installed on the side of the active cavity 4, a disassembly mechanism 3 is installed on one end of the mounting strip 5, the disassembly mechanism 3 includes a connecting block 31, one end of the connecting block 31 is slidably installed in the mounting strip 5, a side groove 32 is provided in the mounting strip 5, the connecting block 31 and the side groove 32 are adapted, symmetrical perforations 33 are provided on the side of the mounting strip 5, an inner cavity 36 is provided in the connecting block 31, an elastic sheet 35 is installed in the inner cavity 36, symmetrical beads 34 are installed on the elastic sheet 35, the perforations 33 are adapted to the beads 34, a tooth block 7 is provided on the side of the mounting strip 5, and a fixed One end of the fixed block 21 is matched with the tooth block 7, and one end of the mounting strip 5 is symmetrically installed with a stop block 6, which is matched with the opening of the movable cavity 4. One end of the elastic sheet 35 is installed on the inner wall of the inner cavity 36, and the side of the elastic sheet 35 has a certain elasticity. When replacing the scraper 9, the elastic sheet 35 is compressed by pressing the stop bead 34 on the side of the mounting strip 5, and the stop beads 34 at both ends are separated from the perforations 33, canceling the fixation of the connecting block 31, taking out the connecting block 31 from the side groove 32, and replacing the wiper as a whole. After the replacement is completed, continue to press the stop bead 34 to push the connecting block 31 into the side groove 32. When sliding to the perforation 33, the elastic sheet 35 drives the stop bead 34 to connect with the perforation 33, limits the connecting block 31, and completes the replacement of the scraper 9 without the aid of any tools, thereby improving the work efficiency of the operator.

[0024] The working principle is as follows: when the position of the scraper 9 needs to be adjusted, it is adjusted through the mounting strip 5 on the side of the wiper bracket body 1. First, hold the fixing block 21 from the position of the notch 22, pull the fixing block 21 to drive the slider 24 to slide in the slide groove 23, the spring 25 is compressed, and the front end of the fixing block 21 is separated from the tooth block 7. At this time, the mounting strip 5 can be pulled to slide in the movable cavity 4. After adjusting to a suitable position, release the fixing block 21. The elastic force of the spring 25 is released to drive the slider 24 to return, and then drive the front end of the fixing block 21 to engage with the tooth block 7 to fix the position of the mounting strip 5. A stop block 6 is installed on the side of the mounting strip 5. The diameter of the stop block 6 is larger than the opening of the movable cavity 4 to ensure that the mounting strip 5 will not be completely separated from the movable cavity 4 after being pulled. When the scraper 9 needs to be replaced, By pressing the beads 34 on the side of the mounting strip 5, the elastic sheet 35 is compressed, and the beads 34 at both ends are separated from the perforations 33, thereby canceling the fixation of the connecting block 31, taking out the connecting block 31 from the side groove 32, and replacing the wiper as a whole. After the replacement is completed, continue to press the beads 34 to push the connecting block 31 into the side groove 32. When it slides to the perforation 33, the elastic sheet 35 drives the beads 34 to connect with the perforations 33, limits the connecting block 31, and completes the replacement of the scraper 9. A damper 8 is installed at the lower end of the connecting block 31 to reduce vibration when the scraper 9 is working, thereby producing a certain protective effect. This method of replacing the scraper 9 does not require the aid of any tools, reduces the time for the operator to replace the scraper 9, and improves the operator's work efficiency.

When the position of the scraper 9 needs to be adjusted, it is adjusted through the mounting strip 5 on the side of the wiper bracket body 1, first grip the position of the notch 22 Hold the fixed block 21, pull the fixed block 21 to drive the slider 24 to slide in the slide groove 23, the spring 25 is compressed, and the front end of the fixed block 21 is separated from the tooth block 7. At this time, the mounting strip 5 can be pulled to slide in the active cavity 4. After adjusting to a suitable position, release the fixed block 21, and the elastic force of the spring 25 is released to drive the slider 24 to return, thereby driving the front end of the fixed block 21 to engage with the tooth block 7 to fix the position of the mounting strip 5. A stop block 6 is installed on the side of the mounting strip 5. The diameter of the stop block 6 is larger than the opening of the active cavity 4 to ensure that the mounting strip 5 will not exceed the opening of the active cavity 4 after being pulled. The remaining features are the same as those in Example 1.
