Abstract

A frameless windshield wiper connector comprises a body. Two ends of the body are buckled inwards to form a hook, and two steel plates are tightly fixed and embedded inside the hook. Windshield wiper rubber bars are embedded and positioned in two lateral sides of the two steel plates. The body is a plastic rubber body, and a group of positioning convex granules is arranged at the place that the inner surface of the body cooperates with the steel plates. The two steel plates are positioned at the positioning convex granules to form concave holes, and the convex granules are embedded in the concave holes to position the steel plates on the plastic rubber body. Since the connector body is made of plastic rubber pieces, the connector has light weight and more reliable technique, and the connector can resist cold and hot temperature transformation. The added positioning convex granules can ensure tightness of the steel plates, control the position of the steel plates on the main body, and ensure freedom degree of the rubber bars. The self fastening type structure is convenient for loading, unloading and replacing, without destroying the body and the steel plates.

Description

A kind of Frameless windshield wiper joint

Technical field:

The utility model relates to a kind of vehicular spare parts, especially loads and unloads simply, changes easily and use the Frameless windshield wiper joint relevant from the automobile of fastening structure with a kind of.

Background technology:

Existing Frameless windshield wiper joint, its structure such as Fig. 1, Fig. 2, shown in Figure 3, it comprises the joint body 1 ' of metallic stamping pieces or foundry goods, the body both ends formation hook portion that bends inwards, two steel plates, 2 ', 3 ' fastening being embedded in described hook portion, rain brush rubber strip 4 ' embeds two steel plate sides location, and there is following shortcoming the joint of this kind structure in it:

1, because body is metallic stamping pieces or foundry goods, its Heavy Weight, the danger factor that have sand holes, steam bubble etc. to be difficult for finding out;

2, steel plate is fixed shakiness, is easily come off;

3, owing to the instability of steel plate position, its tightness is poor, can't guarantee its position in joint body, easily adhesive tape is caused extruding, can't guarantee the degree of freedom of adhesive tape;

4, steel plate with belong to Embedded hard connection being connected of metal joint, can't dismantle or change.

Summary of the invention:

The utility model purpose is to overcome above-mentioned shortcoming, and a kind of Frameless windshield wiper joint is provided, and it adopts from fastening mode, simple in structure, replacing, easy to loading and unloading.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of Frameless windshield wiper joint, comprise: body, the body both ends formation hook portion that bends inwards, two steel plates are fastening to be embedded in described hook portion, the rain brush rubber strip embeds two steel plate sides location, and described body is a plastic body, and is provided with one group of protruding grain in location in inside face and steel plate cooperation position, two steel plates are positioned at protruding grain place, location and form shrinkage pool, and described protruding grain embeds the position of fixing steel plate in the plastic cement body in the shrinkage pool.

The protruding grain in described location is four to six, is symmetrical arranged respectively at body internal surface.

Adopt technique scheme, its advantage is:

1, because joint body adopts plastic parts, and it is in light weight, and technology is more secure, the intensity height, shock resistance is good, and shape stability is good, cold-resistant hot temperature inversion;

2, owing to increase by 4-6 protruding grains in control location, can guarantee the fastening of steel plate, control its position in main body, guarantee the degree of freedom of adhesive tape;

3, owing to its structure from fastening-type, loading and unloading, replacing are all convenient, can not cause the destruction to body and steel plate.

Description of drawings:

Below with accompanying drawing the utility model is described in detail:

Fig. 1 is the three-dimensional decomposition texture scheme drawing of the utility model prior art;

Fig. 2 is the unitized construction scheme drawing of the utility model prior art;

Fig. 3 is the cross-sectional view of the utility model prior art;

Fig. 4 is a three-dimensional decomposition texture scheme drawing of the present utility model;

Fig. 5 is a unitized construction scheme drawing of the present utility model;

Fig. 6 is a cross-sectional view of the present utility model.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is described in detail:

As Fig. 4-embodiment of the present utility model shown in Figure 6, a kind of Frameless windshield wiper joint, comprise: body 1, body 1 both ends bend inwards and form hook portion 11, two steel plates, 2,3 fastening being embedded in described hook portion 11, rain brush rubber strip 4 embeds two steel plate sides location, described body 1 is a plastic body, and be provided with one group of protruding grain 12 in location in inside face and steel plate cooperation position, two steel plates are positioned at protruding grain place, location and form

shrinkage pool

21,31, and described protruding grain 12 embeds the position of fixing steel plate in plastic cement body 1 in the shrinkage pool 21,31.In actual use, the protruding grain in described location is four to six, is symmetrical arranged respectively at body internal surface.

Adopt technique scheme, because joint body adopts plastic parts, it is in light weight, and technology is more secure, the intensity height, and shock resistance is good, and shape stability is good, cold-resistant hot temperature inversion; And owing to increase by 4-6 protruding grains in control location, can guarantee the fastening of steel plate, control its position in main body, guarantee the degree of freedom of adhesive tape; Because its structure from fastening-type, loading and unloading, replacing are all convenient, can not cause the destruction to body and steel plate.
