Description

The windshield wiper rod connector of improvement

The utility model relates to a kind of windshield wiper rod connector of improvement, especially refer to a kind of adaptor union must for connect terminal for the plain film shape, collude end, can be for assembling latch or have the swing arm of latch, thereby bigger use elasticity must be arranged.

Press, when automobile travelled in the rainy day, must push the raindrop of beating on Windshield aside by two brushes, steerman can be known and sees the place ahead.

And the type of drive of windshield wiper, as Fig. 9 and shown in Figure 10, the swing arm a end in a driver train drives is assembled on the rain brush skeleton c by a connector b, makes this rain brush skeleton c reciprocally swinging so that raindrop are pushed aside; Wherein this rain brush skeleton c has a drive-connecting shaft c1, and has a snap groove b1 on this adaptor union b, this adaptor union b must be buckled on the drive-connecting shaft c1 of rain brush skeleton c by snap groove b1, the end of this adaptor union b has a slot b2 again, has a shell fragment b3 in this slot b2 below, and on this slot 2, has a knock hole b4, and the end of this swing arm a is a tabular, has a salient point a1 thereon, must be the slot b2 that flat swing arm a inserts adaptor union b with end, and the salient point a1 on the swing arm a end is upwards depended on knock hole b4 into slot b2 top by shell fragment b3, adaptor union b being assembled in swing arm a end, and snap onto on the rain brush skeleton c by adaptor union b.

Figure 11 and shown in Figure 12 and for example, this adaptor union e must be a U type clip d, and the bending place at U type clip d has a catching groove d1, this U type clip d must be on catching groove d1 clip rain brush skeleton c drive-connecting shaft c1, and the end of this swing arm a is to collude end a2, this swing arm a must hold the a2 hook on U type clip d by colluding of its end, makes this swing a assemble rain brush skeleton c by U type clip d.

Figure 13 and shown in Figure 14 and for example, this adaptor union b must be a U type adaptor union e with two catching groove e1, e2, other has a movable latch f to pass across the perforation c2 of rain brush skeleton c, and this catching groove e2 must be buckled on the movable latch f, and another catching groove e1 of this U type adaptor union e must be buckled on the drive-connecting shaft c1 of rain brush skeleton c, so that U type adaptor union e is assembled on the rain brush skeleton c, the outer end of movable latch f then is fixed on an end to have on the swing arm a of fixed orifice a3, makes this swing arm a assemble rain brush skeleton c by U type adaptor union e.

Because the pattern of the swing arm a end of the driver train of various automobile is had nothing in common with each other,, then must select for use adaptor union b, the U type clip d or the U type adaptor union e side that are applicable to this kind swing arm a to be assembled two brush skeleton c if rain brush damages in the time of must changing; Therefore,, then must make the adaptor union of various different types for the rain brush component maker, thus comparatively trouble inconvenience on making, and manufacturing cost is higher; For the maintainer, must distinctly select suitable adaptor union again again, maybe can't find suitable adaptor union as if in short supply for the moment, then can't change and repair, it is inconvenient therefore comparatively to bother.

The purpose of this utility model is to provide a kind of windshield wiper rod connector of improvement, and it connects the terminal swing arm that is the plain film shape, colludes end, can supply the assembling movable latch or have latch, thereby bigger use elasticity must be arranged.

The purpose of this utility model is achieved in that a kind of windshield wiper rod connector of improvement, be assembled on the rain brush skeleton by a connector at the swing arm end, and having a drive-connecting shaft and two relative perforation on this rain brush skeleton, this adaptor union gets the drive-connecting shaft of snapping rain brush skeleton; It is characterized in that: adaptor union respectively is formed with a lateral plate in arcuation transverse part both sides, and has a pivot joint catching groove below the arcuation transverse part, and this adaptor union is buckled on the drive-connecting shaft of rain brush skeleton by articulating catching groove; An end of the arcuation transverse part of this adaptor union has a shell fragment between two lateral plates again, and above being positioned at shell fragment between two lateral plates, has a structure sheet, on this structure sheet, has a knock hole, and between shell fragment and structure sheet, form a jack, and the tabular swing arm that an end is had salient point is inserted in this jack, and the salient point of plain film shape swing arm is inserted in the knock hole of structure sheet; The arcuation transverse part other end of this adaptor union medial surface below that is positioned at two lateral plates respectively has a projection and respectively has a block at two lateral plate the place ahead medial surfaces again, and between two projections and arcuation transverse part, form an inner buckle groove, catching groove outside the projection outside forms, and an end is the swing arm that colludes end to be colluded on the arcuation transverse part, and the end that colludes of swing arm buckles into inner buckle groove, outer catching groove, and leans against colluding on the side, the end outside of swing arm by block; Has an arcuation slot in the arcuation transverse part below of adaptor union in addition, and a movable latch is set in the two relative perforation of rain brush skeleton, and the arcuation slot of the arcuation transverse part below of adaptor union is buckled on this movable latch, and this movable latch outer end is fixed on an end and has on the swing arm of fixed orifice.

Described latch directly is fixed on the swing arm end, and this swing arm with latch gets the perforation of directly passing the rain brush skeleton, and the arcuation slot of adaptor union is buckled on this latch.

Owing to adopt such scheme: can or have the swing arm of latch for the assembling movable latch, thereby bigger use elasticity must be arranged.
