Description

Technical Field

[0001] This utility model relates to the field of motor vehicle windshield wiper technology, and in particular to a locking structure for a fluid element and a mounting base. Background Technology

[0002] Currently, some windshield washer blades integrate the mounting base and the fluid element into a single part, serving as both a connection to the wiper arm adapter and a water guide. Others separate the mounting base and the fluid element into separate parts before assembly. In the latter case, the fluid element moves only in the longitudinal direction through the gap between the mounting base and the wiper arm adapter, making it impossible to lock completely. This can lead to loosening during use, causing changes in the spray direction or localized stress that can result in breakage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the problem that the fluid element can only move in the longitudinal direction through the gap between the fixed seat and the scraper adapter in the current method of setting the fixed seat and the fluid element as separate parts and then assembling them, which cannot be completely locked. The present invention provides a locking structure for the fluid element and the fixed seat, which locks the fluid element to the fixed seat in the longitudinal direction and prevents it from moving through the gap.
