Abstract

An improved flat wiper blade joint comprises a body; a positioning component is arranged on the body, two steel plates are tightly embedded in the positioning component, wiper rubber strips are embedded into the side edges of the two steel plates and positioned, the positioning component comprises limit retainers, two end parts on both sides of the body are bent upwards to form the limit retainers, two lateral sides close to the middle part of the body are bent upwards to form positioning convex blocks, positioning holes corresponding to the positioning convex blocks are respectively formed on the two steel plates, the positioning convex blocks extend to the positioning holes and are bent outwards to clamp the two steel plates and be positioned together with the retainers on both ends; the positioning convex blocks bent outwards in the middle are coordinated and positioned with the limit retainers on both ends to realize the positioning of the joint body and the two steel plates, so the two steel plates are tightly clamped in the middle and positioned firmly, so as to further ensure the mounting firmness of the rubber strips; the positioning holes of the steel plates are arranged on the tangential positions of the radian vertex of the steel plates and the body to ensure the radian state of the steel plates during forming process, the DOF of the rubber strips is ensured and the effect of the flat wiper blade is better.

Description

A kind of improved Frameless windshield wiper joint

Technical field:

The utility model relates to a kind of vehicular spare parts, and is relevant with a kind of rain brush joint, and especially with a kind of firm position, the automobile from fastening structure of scraping the water better effects if is relevant with the Frameless windshield wiper joint.

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 bend inwards and form hook portion 11 ', 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, steel plate is fixed shakiness, is easily come off;

2, owing to its locate mode, destroyed the radian state of steel plate forming, influence the effect of windscreen wiper greatly.

Summary of the invention:

The utility model purpose is to overcome above-mentioned shortcoming, and a kind of improved Frameless windshield wiper joint is provided, and it is simple in structure, firm position, to scrape water effective.

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

A kind of improved Frameless windshield wiper joint, comprise: body, body is provided with positioning component, two steel plates are fastening to be embedded in described positioning component, the rain brush rubber strip embeds two steel plate sides location, described positioning component comprises the limit block that both sides, body both ends upwards are bent to form, the nearly dual-side in body middle part upwards is bent to form locating convex block, corresponding locating convex block position forms knock hole respectively on two steel plates, locating convex block extend in the knock hole and outwards bending block two steel plates and locate with the two ends block.

Knock hole is arranged at the summit and the tangent position of body of steel plate radian on the described steel plate.

Adopt technique scheme, its advantage is:

1, since joint body the location of two steel plates is adopted in the middle of the two outwards locating convex blocks of bending and the cooperation location of two ends limit block, make two steel plates being clamped between body tightly, firm position, and then also guaranteed the installation firmness of adhesive tape;

2, be arranged at the summit and the tangent position of body of steel plate radian owing to knock hole on the steel plate, the radian state when having guaranteed steel plate forming, the degree of freedom of assurance adhesive tape, windscreen wiper better effects if.

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 improved Frameless windshield wiper joint, comprise: body 1, body is provided with positioning component 11, two

steel plates

2,3 fastening being embedded in described positioning component, rain brush rubber strip 4 embeds two steel plate sides location, described positioning component 11 comprises the limit block 111 that both sides, body both ends upwards are bent to form, the nearly dual-side in body middle part upwards is bent to form locating convex block 112, two steel plates 2, corresponding locating convex block position forms knock hole 21 respectively on 3,31, locating convex block 112 extend into knock hole 21, in 31 and outwards bending is blocked two steel plates and with two ends block 111 location.

Best mode is summit and the tangent position of body that knock

hole

21,31 is arranged at the steel plate radian on the described steel plate.

Adopt technique scheme, because the cooperation location of two locating convex blocks that outwards bend and two ends limit block in the middle of joint body adopts the location of two steel plates, make two steel plates being clamped between body tightly, firm position, and then also guaranteed the installation firmness of adhesive tape; And because employing is fastening with the tangent position of elastic steel sheet arc apex single-point, cooperate outer 4 spacing controls, under the situation that does not influence the steel disc performance, guaranteed the reliability of connection mode.

Claims

1. improved Frameless windshield wiper joint, comprise: body, body is provided with positioning component, two steel plates are fastening to be embedded in described positioning component, the rain brush rubber strip embeds two steel plate sides location, it is characterized in that: described positioning component comprises the limit block that both sides, body both ends upwards are bent to form, the nearly dual-side in body middle part upwards is bent to form locating convex block, corresponding locating convex block position forms knock hole respectively on two steel plates, locating convex block extend in the knock hole and outwards bending block two steel plates and locate with the two ends block.
