Abstract

A safety fastener structure for wiper blades comprises a wiper for bearing wiper blades and a connector for connecting the wiper with a wiper arm, wherein the connector is disposed in a connecting frame. The safety fastener structure is characterized in that a safety fastener is arranged between one end of the connecting frame and the connector and is hinged through two hinge holes respectively arranged on end faces of two side walls of the connector and penetrating through the side walls, a portion of the safety fastener close to the front end is bent into a bracket with a G-shaped section, the outer end face of the bracket is a concave arc face, and a bent portion of the wiper arm extending into the tail end of the connector frame is rested on the concave arc face. The safety fastener structure for wiper blades is simple in structure, fine in stability and easy in production.

Description

A kind of Wiper blade safety catch structure

Technical field

The utility model relates to a kind of Wiper blade safety catch structure.

Background technology

Wiper blade is the spare and accessory parts of automobile, and the safety catch structure of the part that existing brush arm is connected with brush body all is to adopt plug-in card type, and promptly in the adapter that brush arm is packed into brush body links to each other, an end of safety catch directly inserts in the set draw-in groove of adapter madial wall.In use, will occur moving when brush arm, safety catch breaks away from draw-in groove and makes rain brush give the power deficiency, perhaps is stuck in the phenomenon on the vehicle window.

Summary of the invention

The utility model is exactly to have proposed a kind of safety catch and the engaged rain brush safety catch structure of brush arm in order to solve top deficiency.

The technical solution adopted in the utility model is:

A kind of Wiper blade safety catch structure, comprise brush body in order to supporting brush sheet, and the adapter that makes brush body and brush arm tipping, place connecting frame in the adapter, it is characterized in that: be provided with a safety catch between described connecting frame one end and the adapter, safety catch is hinged by a set respectively hinge hole that runs through sidewall of adapter two side end face, the carriage that it is the G type that the part of close safety catch front end is bent to form a section, this carriage outer end face is a concave arc degree face, and the terminal sweep that described brush arm gos deep into connecting frame drops on the concave arc degree face.

Positive role of the present utility model is as follows: owing to adopt above structure, brush arm and safety catch form an interlocking pattern, and the brush arm side travel all is unlikely to influence the safety catch end and is disengaged device, thereby improve the stability that rain brush uses, and simple in structure, be easy to produce.

Description of drawings

Fig. 1: the section-drawing that is a kind of Wiper blade safety catch of the utility model structure;

Fig. 2: the scheme drawing that is a kind of Wiper blade safety catch of the utility model structure.

Among Fig. 1,2: safety catch 1, carriage 11, concave arc degree face 12, brush arm 2, connecting frame 3, adapter 4, hinge hole 41, brush body 5.

The specific embodiment

As shown in Figure 1, 2.

A kind of Wiper blade safety catch structure, comprise brush body 5 in order to supporting brush sheet, and the adapter 4 that brush body 5 and brush arm 2 are hinged with, place connecting frame 3 in the adapter 4, it is characterized in that: be provided with a safety catch 1 between described connecting frame 3 one ends and the adapter 4, safety catch 1 is hinged by a set respectively hinge hole 41 that runs through sidewall of adapter 4 two side end faces, the carriage 11 that it is the G type that the part of close safety catch 1 front end is bent to form a section, these carriage 11 outer faces are a concave arc degree face, and the terminal sweep that described brush arm 2 gos deep into connecting frame 3 drops on the concave arc degree face.

When assembling, safety catch 1 is in open mode, with brush arm 2 connecting frame 3 of packing into, it is the end of the carriage 11 of G type that brush arm 2 terminal sweeps touch the cross section that safety catch 1 fore-end is bent to form, safety catch 1 is along with brush arm 2 gos deep into, the concave arc degree face 12 of carriage 11 slowly rises with brush arm 2 sweeps and contacts and draw close, to the end, the moment hand one that brush arm 2 enters is fully exerted oneself, and the end of carriage 11 is goed deep in the connecting frame 3 fully and concave arc degree face 12 forms an interlocking pattern mutually with brush arm 2 sweeps.

Owing to adopt a kind of Wiper blade safety catch structure of above structure, brush arm and safety catch form an interlocking pattern, and the brush arm side travel all is unlikely to influence the safety catch end and is disengaged device, thereby improve the stability that rain brush uses, and simple in structure, are easy to produce.

The above only is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims

1. Wiper blade safety catch structure, comprise brush body in order to supporting brush sheet, and the adapter that makes brush body and brush arm tipping, place connecting frame in the adapter, it is characterized in that: be provided with a safety catch between described connecting frame one end and the adapter, safety catch is hinged by a set respectively hinge hole that runs through sidewall of adapter two side end face, the carriage that it is the G type that the part of close safety catch front end is bent to form a section, this carriage outer end face is a concave arc degree face, and the terminal sweep that described brush arm gos deep into connecting frame drops on the concave arc degree face.
