Description

Improved apparatus of joint for wiper with screw mounting

The utility model relates to the joint modifying device of the fixing rain brush of a kind of screw, this device has embedding hole and pressing plate on body frame central authorities axis hole, and be provided with the main female joint of overlapping hook triangle abaculus and being provided with link span in a side forwardly, thereby, with the Wiper arm of multiple pattern all can be chimeric easily.

By the fixing Wiper structure (seeing also) of general common screw as Fig. 1 and 2, it is mainly by body frame 1 and support 2 and rain brush rubber 3, a supporting blade 4 and a fixed mount 5 constitute, its medium-height trestle 2 is located at side under the body frame 1, and Fang Ze is provided with supporting blade 4 under the support 2, and on supporting blade 4, be provided with rain brush rubber 3, for making rain brush itself can swing and adjust with it in use, the spy strides centre among body frame 1 and establishes a ㄇ type fixed mount 5, fixed mount 5 is fixed by the open-work 52 of fixed mount 5 and the open-work 10 of body frame 1 by rivet 51, and 1 of fixed mount 5 and body frame are provided with the pad 6 of a lubricating effect, elsewhere, in one of fixed mount 5 side, can fix by screw and the open-work on it 71 for making Wiper arm 7, establish a link span 53 at its side, and be provided with open-work 54 thereon, this kind structure is quite time-consuming taking a lot of work when assembling, not only must have instrument with rivet 51 rivetings on body frame 1 and ㄇ type fixed mount 5, and its strength can not be too big, otherwise the two can be unmovable, often cause substandard products, otherwise, can cause its rain brush itself loosening as too gently also not all right.

Moreover, when assembling, it must aim at the open-work 52 of the two and pad 6,10 and 61, rivet 51 can be penetrated, set therebetween pad 6 must be contained in the two narrow space, assembling is difficulty quite, except that time-consuming taking a lot of work, also increase cost burden, and the body frame 1 of rain brush commonly used own is a riveted with fixed mount 5, as runs into the Wiper arm of difference, and the occasion that utilization hooks together as desire then can't be used, like this, it is quite little to cause its use to go up Applicable scope, and all this kind shortcoming is scolded by dealer and customer always, and suffer from not having good plan, therefore, having to provide a kind of applicable to multiple Wiper arm, more convenient on use operation and assembly, fast and have a joint modifying device of the fixing rain brush of the screw of practicality.

Main purpose of the present utility model provides the joint modifying device of the fixing rain brush of a kind of screw, its assembly, manipulates quite fast easily, and can cost-cutting and combination man-hour, very practical.

Another purpose of the utility model provides the joint modifying device of the fixing rain brush of a kind of screw, and it can be used with multiple Wiper arm to reach by being used of box to pin.

Because the impracticable and many shortcomings that produced on the prior art structure, the inventor is to be engaged in the Specialty Design experience of rain brush for many years, through making great efforts research and development, with the joint modifying device of the fixing rain brush of the screw that the utility model is provided, it mainly is the clamping hole of establishing in male joint the place ahead with the V-type mouth; This clamping hole cooperates with the axial region of body frame central authorities, and be before and after the central authorities of lower stop piece on the male joint of I type, respectively be provided with respectively for Wiper arm or female embedding hole and abaculus that connects cooperation, and Fang Ze establishes a main cover hook that can hook together with male joint before the female joint, its rear is provided with the abaculus that engages with embedding hole, male joint top, and its side is extended with and can be fixedly coupled frame with Wiper arm.Establish an open-work on this link span,, thereby reach the purpose of practicality more so that brush arm cooperates with female joint.

Following conjunction with figs. and shown in embodiment, the architectural feature using method and the functional purpose of the utility model described in further detail, wherein,

Fig. 1 is the three-dimensional exploded view of common structure.

Fig. 2 is the three-dimensional combination figure of common structure.

Fig. 3 is the three-dimensional exploded view of the utility model.

Fig. 4 is the three-dimensional combination figure of the utility model.

Fig. 5 is the sectional axonometric drawing of the utility model.

Fig. 6 is another running condition figure of the utility model.

See also shown in Fig. 3,4, it mainly is that its place ahead is provided with the clamping hole 82 of a V-type mouth by an I type male joint for the utility model, and its effect is to insert to be embedded on the set axial region 111 in body frame 1 middle part to fix.And the following last lower stop piece 83,84 that respectively is provided with for the Wiper arm 7 that is coated and fixed on the I type male joint 8, and the front and back, centre are respectively equipped with an embedding hole 831 and triangle abaculus 841 among being positioned at lower stop piece 83,84, triangle abaculus 841 is located at lower stop piece 84 central authorities and is on the curved down pressing plate 85 of summary, the position in embedding hole 831 then than triangle abaculus 841 forward, its objective is and avoid different types Wiper arm 7 and chimeric, as for the effect of pressing plate 85 is after itself and the crotch shape Wiper arm 7 that has embedding hole 72 are chimeric, works the effect of pushing and also can separate.

Female joint 9 is provided with a main cover hook 91 in its place ahead, then be provided with abaculus 92 below its rear, it is enclosed within on I type male joint 8 the place aheads on the lower stop piece 83,84,92 of the abaculus of female joint 9 simultaneously are embedded on the embedding hole 831 above the male joint, because main cover hook 91 its length are too late in the triangle abaculus 841 that is located on lower stop piece 84 middle parts (being pressing plate 85), so pressing plate 85 can not be affected.During the two tabling, when soon axial region 111 front and back of body frame 1 are coated and fixed, can realize that quite firm fixing can not get loose, and the master of female joint 9 cover hook 91 1 sides are provided with link span 93, and link span 93 is provided with for the fixing open-work 94 of set open-work 71 screw threads on screw and the Wiper arm 7, and main cover hook 91 and 93 of link spans have been provided with the strengthening rib 95 of humidification.

The utility model is (seeing also shown in Figure 5) quite easily in use, the clamping hole 82 of male joint 8 is embedded on the body frame 1 central axial region 111, master's cover hook 91 with female joint 9 is sleeved on male joint 8 side before again, utilizes the set abaculus 92 in its below and embedding hole 831 chimeric being integral of male joint 8 tops to get final product simultaneously.Please close with reference to shown in Figure 6, it be the embodiment that the utility model combines with crotch shape Wiper arm 7, and owing to this Wiper arm crotch subordinate square end is provided with an embedding hole 72, when cooperating with male joint 8, the triangle abaculus on the pressing plate 85 of this embedding hole 72 and male joint 8 cooperates.

In sum, according to the utility model, box to pin 8,9 cooperatively interacts the cooperation that is suitable for various different types Wiper arms 1 can be provided, it is quite easy in operation simultaneously, the utility model design-calculated structure makes the fixed mount 5 commonly used of must screw fixing joint, make fit on more quick and convenient, connect firmly, have practical effect, thereby the utility model has overcome the prior art shortcoming.
