Specific implementation mode

To further illustrate that each embodiment, the utility model are provided with attached drawing.These attached drawings are in the utility model discloses A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain that the running of embodiment is former Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

The utility model is further illustrated in conjunction with the drawings and specific embodiments.Fig. 2 shows new according to this practicality The wiper connection structure of type embodiment.The wiper connection structure may include fixed seat 1 and connection cover 2.Wherein, fixed seat 1 is integrally formed.Preferably, fixed seat 1 is made of kirsite.Therefore, 1 intensity of fixed seat is high.Fixed seat 1 may include rectangular base 11 and clamping portion 12.The long side both sides of rectangular base 11 are formed with card slot 111.Rectangular base 11 can pass through card slot 111 and rain The spring bearer plate 31 of scraping article 3 is clamped and is fixedly mounted on windscreen wiper item 3, as shown in Figure 3.For the sake of removing, eliminated in Fig. 3 Surround the protective case of fixed seat 1.The structure of windscreen wiper item 3 is the prior art, is not described further herein.

In a preferred embodiment, the card slot 111 per side includes two card slot sections positioned at both ends.Certainly, card slot 111 also may be used To be arranged along the length of entire rectangular base 11.

Clamping portion 12 is vertically set on the centre of rectangular base 11.Its length is equal to the length of rectangular base 11, i.e., along square The whole length of shape bottom 11 extends；Thickness is the 1/4 to 1/3 of the width of rectangular base 11.Therefore, the intensity ratio of clamping portion 12 The intensity of the riser of the prior art is high, it is not easy to which, from fracture of root, service life extends.In general, the height of clamping portion 12 is than existing There is the height of the riser 12 ' of technology low, this is convenient for the installation of Wiper arm.

The top center of clamping portion 12 forms the horizontal axis 13 of oriented both sides definite length extended.Preferably, the pre- fixed length Thickness of the degree equal to the clamping portion.The effect of horizontal axis 13 is as the effect of the horizontal axis 13 ' of the prior art.Horizontal axis 13 has axis To through-hole 131.Axially extending bore 131 is used to coordinate with the bolt of corresponding wiper arm.The aperture of axially extending bore 131 is slightly larger than corresponding rain The diameter of the bolt of scraping arm.Preferably, the wall thickness of horizontal axis is 2-5 millimeters.

Preferably, the top center highest of clamping portion 13, the different height in both sides.This enables the connection cover 2 being clamped with it Horizontally rotate angle there are one enough, and then keeps contact of the windscreen wiper item with windshield closer.In the shown embodiment, clamping portion 13 top center is arc-shaped, it is minimum be on one side it is flat, another side tilts down.

As shown in Figures 2 and 4, connection cover 2 includes that the integrally formed fixed seat interconnecting piece 21 being arranged side by side and wiper arm connect Socket part 22.Fixed seat interconnecting piece 21 is the ducted body that lower section opens, and downward open and orthogonal resigning is arranged inside Slot 211 and card slot 212, recessing groove 211 is for receiving clamping portion 12, card slot 212 to be used to be clamped with horizontal axis 13.When clamping portion 12 connects It is contained in recessing groove 211, and when horizontal axis 13 is connected in card slot 212, connection cover 2 is bonded in fixed seat 1.Fixed seat connects The lateral wall in portion 21 is equipped with through-hole 213, and through-hole 213 is aligned with axially extending bore 131.Through-hole 213 and axially extending bore 131 are used In the bolt (not shown) for receiving wiper arm.Preferably, through-hole 213 is identical as the aperture of axially extending bore 131.Wiper arm interconnecting piece 23 have the matched structure of connecting seat with the wiper arm.It is noted that wiper arm interconnecting piece 23 and wiper arm herein It is the prior art, no longer its concrete structure is described herein.

It is briefly described as follows the process that windscreen wiper item and wiper arm are attached by the utility model.First, fixed seat 1 is solid Dingan County is mounted in windscreen wiper item 3 (as shown in Figure 3), then clamping portion 12 and horizontal axis 13 of the connection cover 2 by its fixed seat interconnecting piece 21 It is clamped and is bonded in fixed seat 1 (as indicated by the arrows of fig. 2), last wiper arm is inserted into through-hole 23 by its bolt and axially leads to In hole 131 and the connecting seat of wiper arm interconnecting piece 23 and the wiper arm coordinates and is bonded on wiper arm.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the scope of protection of the utility model.
