The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail.
Like Fig. 1, shown in 2, a kind of rain brush connection structure that the utility model disclosed mainly comprises brush holder support 1 and adaptor union 2, and adaptor union 2 is used to connect brush holder support and Wiper arm.Said brush holder support 1 is fixedly connected with blade insert A in the bottom; The opening groove 11 that middle part moulding one opening of brush holder support 1 makes progress; The bottom central of this opening groove 11 is absorbed in one and makes a concession groove 12, and its top supplies a shell fragment 13 is set, and makes an end of shell fragment 13 link to each other with the bottom of opening groove 11; Then unsettled moulding one buckle 131 that above yielding groove 12 and in the end, protrudes of the other end; The bottom of this opening groove 11 forms protruding rank 14 in the both sides of shell fragment 13, the vertical surface on these protruding rank 14 is provided with concaveconvex structure 15, again on the sidewall of opening groove 11 before and after at interval be provided with caulking groove 16 and catch 17.
On the detachable opening groove 11 that is installed in brush holder support 1 middle part of said adaptor union 2; Make the bottom construction and the corresponding cooperation of the structure of brush holder support opening groove 11 of this adaptor union 2; Specifically: adaptor union 2 is moulding one boss 21 on the bottom, and the central authorities of this boss 21 are provided with the chute 22 that matches with brush holder support opening groove shell fragment 13, and the vertical surface of boss 21 both sides is provided with the jog 23 with open geosynclinal convex rank 14 concaveconvex structures, 15 corresponding matching; And form the convex tendon 24 and the short slot that cooperates opening groove catch 17 25 that cooperates opening groove caulking groove 16 on the both sides end face of adaptor union 2; When adaptor union 2 is installed in 11 last times of opening groove, this short slot 25 just top supports catch 17 of opening groove sidewall, and convex tendon 24 just is embedded in the caulking groove 16 of opening groove sidewall; Further; Also can be at the terminal moulding one step-like card platform 221 of chute 22, after adaptor union 2 was installed, the buckle 131 of brush holder support shell fragment 13 cooperated with pressed connector 2 with card platform 221.
When adaptor union 2 and brush holder support 1 winding; It is the position of the chute 22 of adaptor union 2 being aimed at brush holder support opening groove shell fragment 13; The top is supported to press down and is made shell fragment be absorbed in yielding groove 12, makes the jog 23 of adaptor union 2 bottoms cooperate the concaveconvex structure 15 of opening the geosynclinal convex rank simultaneously, and adaptor union 2 is slipped into along brush holder support 1 front end; Short slot 25 to the end face of adaptor union both sides pushes up the catch 17 that supports opening groove; Convex tendon 24 embeds in the caulking groove 16 of opening groove sidewalls, at this moment makes the buckle 131 of shell fragment 13 upspring and block platform 221 and cooperate pressed connector 2, with this adaptor union 2 firmly is installed on the brush holder support 1.It is thus clear that the fit structure of above-mentioned brush holder support 1 and adaptor union 2 detachable separation types is convenient to the dismounting and the replacing of brush holder support 1 and adaptor union 2, and brush holder support 1 just can connect with the Wiper arm of different style structures through adaptor union.
Below the specific embodiment that is connected of Wiper arm through adaptor union and existing structure the utility model is described further.
Like Fig. 1, shown in 3, for first embodiment of the utility model supplies to be connected with a kind of side bolt-type Wiper arm 3A.The top of this adaptor union 2 provides a pivot hole 26; A connection piece 27 is enclosed within on the adaptor union 2; This attaching parts 27 is the open ducted body in below; Have a downward opening inverted U draw-in groove 271, the sidewall of attaching parts 27 with pivot hole 26 correspondence positions on be provided with a circular hole 272, and the end face of attaching parts 27 is provided with the slotted eye 273 that several are communicated with draw-in grooves 271; This side bolt-type Wiper arm 3A is an existing structure, and its front end is provided with a pin 31A and a grab 32A.
During assembling; Earlier adaptor union 2 is installed on the brush holder support 1; Afterwards attaching parts 27 is enclosed within on the adaptor union 2; Again the pin 31A of Wiper arm 3A is penetrated the pivot hole 26 of the circular hole 272 and the adaptor union of attaching parts from a side, the grab 32A with Wiper arm buckles in the slotted eye 273 of attaching parts again, can realize that so brush holder support 1, adaptor union 2 are connected with Wiper arm 3A's.
Shown in Fig. 4,4A, be the utility model second embodiment, supply to be connected with a kind of Wiper arm 3B of existing structure.Different with first embodiment is the middle part moulding one V-type fluting 28 of this adaptor union 2 '; And run through a mounting hole 281 in a fluting side of 28, and the side of this fluting 28 is formed with limited step 282, and the inside of adaptor union 2 ' is provided with an elastic card 283 near mounting hole 281 places; The top of adaptor union 2 ' is provided with catching groove 284 in addition again; In the end of catching groove 284 1 sides one pivot 285 is set, supplies to articulate a loam cake 29, the front end of this loam cake 29 cooperates pivot 285 moulding one open slot 291; The middle part of loam cake 29 is provided with two claws 292 in addition, and the rear end is then protruded a briquetting 293 downwards.This Wiper arm 3B is an existing structure, has a downward opening inverted U draw-in groove 31B, and the front end of Wiper arm protrudes two lug 32B forward, formation one fitting surface 33B between this two lug.During assembling, equally earlier adaptor union 2 ' is installed on the brush holder support 1, again loam cake 29 is articulated on the adaptor union 2; Open loam cake 29; Wiper arm 3B is enclosed within on the adaptor union 2 ', and the lug 32B top that makes the Wiper arm front end is behind limited step 282 location of adaptor union 2 ', and loam cake 29 is under pivot 285 rotatable covers; Make two claws 292 of loam cake stretch into fastening in the catching groove 284; Make the briquetting 293 of cover back-end compress the fitting surface 33B of Wiper arm simultaneously, compress Wiper arm, with adaptor union 2 ' and firm the combining of Wiper arm 3B with this.
Shown in Fig. 5,5A,, same for the 3rd embodiment of the utility model; Aforementioned adaptor union 2 ' also can match with another kind of side pin formula Wiper arm 3C and be connected; Wiper arm 3C is an existing structure, and its front end is to side protrusion one pin 31C, during installation; Make the pin 31C of Wiper arm 3C insert in the adaptor union 2 ' mounting hole 281 by a side; Pin 31C can back down the elastic card 283 in the adaptor union 2 ' in the process that stretches through, and inserts the location that compresses that back pin 31C receives elastic card 283 fully, can be with adaptor union 2 ' and Wiper arm 3C mortise.
Above-mentioned visible, because the rain brush brush holder support of the utility model can be connected with the Wiper arm of multiple model and structure is adaptive through adaptor union, improve the commonality and the suitability of rain brush brush holder support.
