[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] The structure of the multi-functional joint connection adapter windshield wiper provided by the present invention is as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown. The windshield wiper includes a connector base 1, a rubber strip, a steel sheet, a sheath and a plug. An installation cavity 11 is provided on the surface of the connector base 1. An upper cover 2 is provided above the connector base 1, and the bottom of the upper cover 2 is inserted into the installation cavity 11. A shaft hole 21 is provided on the surface of the upper cover 2, which facilitates the assembly of the upper cover 2 and the snap ring cover. An installation post 12 is integrally injection molded inside the installation cavity 11. A post groove 22 is provided at the bottom of the upper cover 2. When the upper cover 2 is installed with the connector base 1, the post groove 22 and the installation post 12 are buckled with each other. A buckle slot 13 is provided inside the connector base 1, and the buckle slot 13 communicates with the installation cavity 11. One end of the bottom of the upper cover 2 is integrally injection molded with a buckle part 23; when the upper cover 2 is installed with the connector base 1, the buckle part 23 is inserted into the inside of the buckle slot 13. An extrusion block 14 is provided at one end of the connector base 1 away from the buckle slot 13, and the extrusion block 14 communicates with the installation cavity 11. An inclined surface 24 is provided at one end of the surface of the upper cover 2. During the installation process of the upper cover 2 and the connector base 1, the inclined surface 24 facilitates one end of the upper cover 2 to be inserted into the inside of the installation cavity 11 and is tightly fixed to the surface of the upper cover 2 above the inclined surface 24 through the extrusion block 14.

[0020] During implementation, when the upper cover 2 is assembled, the buckle part 23 will be obliquely inserted into the inside of the buckle slot 13, and then the upper cover 2 is pressed so that the bottom of the upper cover 2 is completely buckled into the inside of the installation cavity 11. At this time, the post groove 22 will match with the installation post 12. One end of the upper cover 2 away from the buckle part 23 will be inserted into the inside of the installation cavity 11 under the action of the inclined surface 24, and at the same time, it will be tightly attached to the inner wall of the installation cavity 11 through the extrusion block 14 and the base 4.

[0021] Furthermore, as Figure 3 and Figure 4As shown, four steel sheet claws 3 and two steel sheet clamping points 32 are integrally injection-molded on the inner wall of the bottom of the connector base 1. The steel sheet clamping points 32 are located between the two steel sheet claws 3. And on one side of the four steel sheet claws 3 on the surface of the connector base 1, a claw receiving groove 31 is provided respectively. And the claw receiving groove 31 communicates with the installation cavity 11. At the same time, the cooperation of the steel sheet claws 3 and the claw receiving groove 31 facilitates the installation and fixation of the connector base 1; on both sides of the bottom of the upper cover 2, there are bases 4, and the bases 4 and the upper cover 2 are integrally injection-molded, eliminating the original hardware parts. And when the upper cover 2 is installed with the connector base 1, the bases 4 are closely attached to the inner wall of the installation cavity 11 to increase the firmness during assembly.

[0022] During implementation, through the mutual cooperation of the steel sheet claws 3 and the claw receiving grooves 31, the installation of the connector base 1 is facilitated, solving the problem that the prior art needs to be fixed by bolts.

[0023] Working principle: When in use, the upper cover 2 and the connector base 1 are assembled. When the upper cover 2 is assembled, the buckle part 23 will be obliquely inserted into the inside of the buckle groove 13. Subsequently, the upper cover 2 is pressed, so that the bottom of the upper cover 2 is completely buckled into the inside of the installation cavity 11. At this time, the column groove 22 will match with the installation column 12. One end of the upper cover 2 away from the buckle part 23 will be facilitated to be inserted into the inside of the installation cavity 11 under the action of the inclined surface 24. At the same time, through the extrusion block 14 and the bases 4 being closely attached to the inner wall of the installation cavity 11, the firmness of the installation of the upper cover 2 and the connector base 1 is increased.

[0024] After the upper cover 2 and the connector base 1 are installed, through the mutual cooperation of the steel sheet claws 3 and the claw receiving grooves 31, the installation of the connector base 1 is facilitated, solving the problem that the prior art needs to be fixed by bolts, reducing the labor intensity during the installation of the wiper joint, and improving the working efficiency during the installation of the wiper joint.

[0025] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
