Description
(1) technical field:
A kind of windshield wiper arm of the utility model connector, relevant with employed bracket for wiper adapter on the windshield, be meant especially a kind ofly can be useful in same thickness small arc degree, the big curved arc degree of same thickness and fixing fully, belong to vehicular spare parts than wearing of the hook type joint Wiper arm of three kinds of specifications such as the big curved arc degree of heavy gauge.
(2) background technology:
Be used in the Wiper arm on the windshield at present, its joint kenel has three kinds, as shown in Figure 1 to Figure 3, be respectively axial pin type joint (Pin type) 10, inserting bolt type joint (Bayonet type) 20 and hook type joint (Hook type) 30, and US Patent the 5th, 611, No. 103 and the 6th, 332, No. 236 disclosed Wiper arm specific binders devices, all can be used on the structure design of axial pin type joint 10 and inserting bolt type joint 20, but can not be applicable on the hook type joint 30 of existing all specifications, have three kinds according to the specification that has hook type joint 30 now, extremely shown in Figure 6 as Fig. 4, first kind hook type joint 30a, its thickness are that 3mm and terminal curved arc degree diameter are 8.8mm (as shown in Figure 4); Second kind hook type joint 30b, its thickness are that the diameter of 3mm and terminal curved arc degree is 11mm (as shown in Figure 5); The third hook type joint 30c, its thickness are that the diameter of 4mm and terminal curved arc degree is 11mm (as shown in Figure 6); Wherein, this US Patent the 6th, 332, be for No. 236 to belong to the design of use on the hook type joint 30b of first kind hook type joint 30a and second kind, (this Fig. 7 and Fig. 8 promptly are this US Patent the 6th to the state of its use as shown in Figures 7 and 8, Fig. 4 and Fig. 5 in 332, No. 236 patent specifications); And this US Patent the 5th, 611, No. 103 is to belong to use in first kind hook type joint 30a and the design on the third the hook type joint 30c, its running condition such as Fig. 9 and shown in Figure 10 (Fig. 9 and Figure 10 promptly are this US Patent the 5th, Fig. 6 (b) and Fig. 6 (a) in 611, No. 103 patent specifications); Yet, this US Patent the 6th, 332, No. 236 Wiper arm connector but can't be assemblied on this third the hook type joint 30c, it is because of the thickness that is this hook type joint 30c too big (as shown in figure 11), leading edge and this document piece 221 (this assembly numbering 22 that after wearing, can surpass this Wiper arm connector arcuation transverse part 22 on the contrary, 221 is to continue to use this US Patent the 6th, 332, Fig. 4 and the figure number among Fig. 5 22 in No. 236 patent specifications, 221) distance between, cause the end top of this hook type joint 30c to be pulled on this link stopper 221, make the side plate on its both sides outwards produce serious deformation, cause the result who can't resilience becomes the clamping function state; In addition, this US Patent the 5th, 611, No. 103 Wiper arm connector then can't be assemblied on this hook type joint 30b of second kind, it is because of being the thickness too little (as shown in figure 12) of this hook type joint 30b, make after being assemblied on this hook type joint 30b of second kind, the end of its crotch portion can't push up the blocks of files 200 of touching this Wiper arm connector front end of pulling, and (this assembly numbering 200 is this US Patent the 5th, 611, figure number 20 among Fig. 5 in No. 103 patent specifications) on, causing can't be by tight clamping between the link stopper 200 on front end link stopper 200 and the center section part front end, in other words, be to have one section space length δ 1 (shown in the 1 figure number position of the δ among Figure 12) between the link stopper 200 of this hook type joint 30b and front end, so this hook type joint 30b and 10 both formation of Wiper arm connector can't fastening mutually chimeric being integral; Therefore the disappearance of the 5th, 611, No. 103 and the 6th, 332, No. 236 maximums of US Patent is exactly hook type joint two brush arms that only can be applicable to its exclusive specification separately, therefore causes the restriction in the use, can't intercourse use.
Main purpose of the present utility model is that a kind of windshield wiper arm connector is being provided, and is made up of one first side plate, one second side plate and a junction; Wherein, convex with one first block on the front end face of this first side plate inner edge surface; This second side plate system and this first side plate size and shape are all identical and be and parallel opposedly, and its inner rim face also convexes with one second block with respect to the position of first block of this first side plate; This connecting portion system is arranged between the inner edge surface of the inner edge surface of this first side plate and second side plate, and it has a top surface, a bottom faces, a front end face and an aft end face, outwards protrudes out the spring clip of a declivity on this front end face; By this declivity spring clip and first link stopper and the formed space of the second link stopper three, and it is fixing than wearing of the hook type joint Wiper arm of three kinds of specifications such as the big curved arc degree of heavy gauge to be applicable to that respectively same thickness small arc degree, the big curved arc degree of same thickness reach.
