Description

Technical Field

[0001] The utility model relates to the technical field of automobile windshield wipers, and more specifically, to a windshield wiper shaft sleeve that is convenient for connection. Background Technique

[0002] An automobile windshield wiper, also known as a wiper or windshield wiper, is a blade structure installed in front of the windshield. It mainly consists of a motor, a reducer, a four-link mechanism, a wiper arm spindle, a wiper blade assembly, etc. Its main function is to sweep away rain, snow, and dust on the windshield that obstruct the line of sight, ensuring that the driver has a clear view during driving, which plays an important role in driving safety. When the windshield wiper is working, the wiper shaft part is particularly vulnerable to external influences. Therefore, the wiper shaft part is usually protected by a windshield wiper shaft sleeve.

[0003] As disclosed in a Chinese patent: A fastening device for a windshield wiper shaft sleeve and a connecting pipe, application number: CN202322968815.6, includes: a windshield wiper connecting pipe and a shaft sleeve. The shaft sleeve is installed inside the automobile rear back panel. An inner hole is provided inside the shaft sleeve. A transmission shaft is installed on the inner surface of the inner hole through a bearing. A clamping seat is installed at the end of the transmission shaft through a clamping groove. A windshield wiper connecting pipe is installed on the top of the clamping seat. A seal is installed at the position of the gap between the outer surface of the shaft sleeve and the automobile rear back panel. A sealing groove is provided on the outer surface of the seal. A sealing boss A is installed on the inner surface of the sealing groove. A sealing boss B is installed on the inner surface of the seal. A fastening device for a windshield wiper shaft sleeve and a connecting pipe solves the problem that the fixing mechanism of the existing windshield wiper shaft sleeve is too simple, and the transmission mechanism is extremely easy to loosen under the long-term swinging action, affecting the subsequent scraping effect of the windshield wiper, improving the installation firmness of the windshield wiper, and at the same time ensuring the scraping effect of the windshield wiper.

If the snapping cannot be performed, rotate the knob 4017. The knob 4017 drives the second bevel gear 4015 to rotate through the second rotating column 4016. The second bevel gear 4015 drives the first bevel gear 4013 to rotate. The first bevel gear 4013 drives the cross slider 4012 to rotate. The cross slider 4012 drives the threaded column 409 to rotate through the cross chute 4011. Then, through the threaded hole 408, the threaded column 409 moves towards the direction of the first bevel gear 4013, and at the same time, it is guided by the cross chute 4011. The threaded column 409 drives the support column 4010 to move, so that the support column 4010 also gradually moves towards the direction of the first bevel gear 4013. The inclined surface of the support column 4010 presses the inclined surface of the slider 404, so that the slider 404 gradually moves outwards from the outside of the second chute 403. The sliding plate 406 follows the slider 404 to move, and the spring 407 deforms, thereby realizing internal expansion fixation through the slider 404. Rotating the knob 4017 can perform internal expansion fixation, which is convenient for connection.
