[0002] At present, cars are a very common means of transportation, and car wipers, as an indispensable part of cars, play an extremely important role.
[0003] The connector of a conventional windshield wiper is generally fixed to the wiper. The existing windshield wiper connector is composed of multiple parts, and the assembly is relatively complicated, which affects the production progress. Summary of the invention
[0004] In order to solve the shortcomings in the prior art, the present invention provides a rotary wiper joint assembly.
[0005] The present invention provides a rotary wiper joint assembly, comprising a joint, a connecting piece and a steel sheet base, wherein the joint is fixed to the upper part of the connecting piece, a rotating column is provided at the middle position of the bottom of the connecting piece, and limiting convex strips are provided at two symmetrical corners of the bottom of the connecting piece, the steel sheet base comprises a fixing plate, symmetrical steel sheet slots are provided in parallel at the bottom of the fixing plate, a center hole is provided at the center position of the fixing plate, the rotating column is inserted into the center hole, so that the connecting piece rotates on the steel sheet base with the rotating column as the axis, arc segments are also provided at the two symmetrical corners of the fixing plate, one end of the arc segment is connected with a corner segment, and the arc segment and the corner segment cooperate with the limiting convex strip.
[0006] Preferably, a card point is extended outward at the bottom edge of the connecting piece, and a card slot is provided at a corresponding position on the edge of the fixed plate. When the connecting piece is rotated into place on the steel sheet base, the card point is inserted into the card slot.
[0007] Preferably, a positioning column is provided at the bottom of the connecting member on one side of the rotating column, and a positioning hole is provided at a corresponding position of the fixing plate.
[0008] Preferably, a notch is formed at the root of the positioning column, so that the diameter of the head of the positioning column is larger than the diameter of the root.
[0009] Preferably, the positioning hole includes an arc hole and a long hole, and the head of the positioning column is inserted into the arc hole. As the connecting piece rotates on the steel sheet base, the notch portion of the positioning column will turn into the long hole. Since the head of the positioning column protrudes outward, the head of the positioning column is stuck on the fixing plate.
[0010] Preferably, the connecting member can rotate on the steel sheet base with the rotating column as the axis to a maximum angle of 25° to 30°.
[0011] The present invention provides a rotary wiper joint assembly, which has the beneficial effects of: the connecting piece and the steel sheet base are directly installed by rotating, which is simple and quick, and improves production efficiency; and card points and card grooves are respectively arranged at one end of the steel sheet base and the connecting piece to avoid installation errors, thereby further improving processing efficiency.

[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0020] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.
[0021] like Figure 1-7As shown, a rotary wiper joint assembly provided in this embodiment includes a joint 1, a connector 2 and a steel sheet base 3, wherein the joint 1 is fixed to the upper part of the connector 2, a rotating column 21 is provided at the middle position of the bottom of the connector 2, and limiting convex strips 22 are provided at two symmetrical corners of the bottom of the connector 2, and the steel sheet base 3 includes a fixing plate 31, and symmetrical steel sheet slots 32 are provided in parallel at the bottom of the fixing plate 31, and a center hole 33 is provided at the center position of the fixing plate 31, and the rotating column 21 is inserted into the center hole 33, so that the connector 2 rotates on the steel sheet base 3 with the rotating column 21 as the axis, and the maximum rotation angle is 25° to 30°. Arc segments 34 are also provided at the two symmetrical corners of the fixing plate 31, and one end of the arc segment 34 is connected to a corner segment 35, and the arc segment 34 and the corner segment 35 cooperate with the limiting convex strip 22.
[0022] The bottom edge of the connector 2 of this embodiment also has a card point 23 extending outward, and a card slot 36 is provided at a corresponding position on the edge of the fixing plate 31. When the connector 2 is rotated into place on the steel sheet base 3, the card point 23 is inserted into the card slot 36. When the connector assembly needs to be disassembled, the card point 23 needs to be pushed upward first to disengage the card point 23 from the card slot 36 before the connector 2 can be rotated on the steel sheet base 3.
[0023] The bottom of the connecting member 2 of this embodiment is located on one side of the rotating column 21 and is also provided with a positioning column 24. A notch 25 is formed at the root of the positioning column 24 so that the diameter of the head of the positioning column 24 is larger than the diameter of the root. A positioning hole 37 is provided at the corresponding position of the fixing plate 31. The positioning hole 37 includes an arc hole 371 and a long hole 372. The head of the positioning column 24 is inserted into the arc hole 371. As the connecting member 2 rotates on the steel sheet base 3, the notch 25 of the positioning column 24 will be transferred into the long hole 372. Since the head of the positioning column 24 protrudes outward, the head of the positioning column 24 is stuck on the fixing plate 31, and the connecting member 2 cannot be pulled out of the steel sheet base 3 longitudinally.
[0024] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
