In accordance with the division of International Patent Classification (IPC), a kind of windshield wiper connecting device, disclosed by this utility model, belongs to the technical field of wiper-arm connection structure, especially about a kind of element that connects the wiper rod with the wiper arm.
The car windshield wiper includes wiper body, connector and wiper arm. Among them usually the connector has a fixed seat and joints, the fixed seat is fixed at the middle part of main body of wiper and the joints are mounted at the fixed seat. After their matching, they are connected with the wiper arm mounted in front of the car glass. Generally speaking, the connector structures are set according to the structure of wiper arm, and most of them adopt a fixed-connection means, a kind of connector matches with a kind of wiper arm. However, all kinds of car wiper arms are different in shape and various in kind, bringing consumers a very heavy limitation while changing and choosing the wiper arm. That any style of wiper can be generally used for installation of any kind of wiper arm with different structure is the technological problem to be solved by the technical staff exactly in this field.
A kind of windshield wiper connecting device, disclosed by Chinese literature 201120190806.3, consists of fixed seat, connecting pieces and top cap through a matching, which may be satisfied with several kinds of wiper arms, but the kind of device is not suitable for other types of wiper arms on the market.

As far as the connection main body (220) is concerned, there is a lower concave surface (223) on the top face, inner notches (224) on both side faces, and segmented side margins (228) at the lower part of two sides, the bulge half-ring in the front is equipped with a movable cap (210), and its two sides of front end of cap (210) has a bulge pressing block (211) each.
The lower concave surface (223) at the top face of connection main body (220) has a match with the n-shaped stop pad (300), at the bottom of both inner sides, there are sticking points (303) that connect separately with the corresponding inner notches (224) of connection main body; at the bottom of both sides of stop pad (300), there are flanged lips (303), and there is a notch stuck-boss (302).
On the side surface of the connection main body (220), there are straight-through circular holes (221) that are used to match with through-hole circular bulge rings (104) on both sides of base; the width of connector (200) head is greater than the width of both sides of connection main body (220).
Further, the wiper connecting device also includes the functional external cap (400), and the cap (400) has a stuck connection with the composite unit of connector (200) and stop pad (300). In the middle of top face of functional external cap (400) there is an opening (401). The straight-through holes are on the straight- through hole (221) position of corresponding connection main body (220) of both sides of functional external cap (401), and through the end face at the trail part (404) and the resilient-strip bosses (226) on both sides under the back end of connector, a fixation is given to limit the slipping out.
Two notch stuck-bosses (302) of stop pad (300) have a corresponding match with the bulge sticking points (402) on the functional external cap (400) respectively.
Further, a resilient strip (222) is set in the middle of connector (200), and inside the strip, there is a stuck boss (230) set; on both sides of connector (200) head there are arc-shaped retaining walls (233), the front end of two retaining walls (233) connect the cap (210); at the back end of main body sets a resilient-strip stuck- boss (226), and at the back end of top face of connection main body sets a stuck boss (225); the position-limiting ditch groove (231) inside the main body, along with the height-limiting ribs(232) at the back of the connection main body (220), achieve a position limiting through their matching.
Inside the cap (210), a passing slot (212) is set, and below it, there is a limit baffle plate (213). The fixed sticking point resilient strips (214) are on both sides of cap (210). The outward-bulge sticking point of this resilient trop is bulged into a corresponding stuck slot on two retaining walls (233). The stuck slot is located on the inner side faceof two retaining walls (233) with a half-opening resilient strip set (227).
The straight-through circular hole (221), located on both side faces of the main body (220) of connection, match the through-hole circular bulge ring (104) into one, which may rotate a certain angle.
Further, the base (100) has a fixed connection with the main body of wiper through the ditch groove at the bottom or through riveting.
After adopting the above-mentioned scheme, this utility model may match with wiper arms with all kinds of structures so as to improve the adaptation of windshield wiper. At the time of installing the connecting device and the wiper arm with any kind of structure, the operation is very simple, and without the help of other tools, a direct disassembly, assembly or replace is feasible.
With the help of the attached diagrams, a further description is given to this utility model:
