Description
Technical field
The utility model relates to chair art, especially relates to a kind of connector of back.
Background technology
In order to meet the requirement of people to comfortableness, people add backrest on the basis of stool, thus create chair.People is when seat, and back can rest on backrest, and such people will feel very comfortable.When people leans on backrest, backrest needs to bear very large pressure, so, if the unstable words of back, not only can not meet the demand of human body to comfortableness, but also people may be caused to come to harm.
Summary of the invention
Based on the shortcoming of above-mentioned existence, problem to be solved in the utility model is to provide that a kind of structure is simple, the connector that can be effectively fastened on by backrest in chair body, ensures the security of back.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of back connector, it is characterized in that: comprise the first plate, the both sides of described first plate are fixed with the second plate and the 3rd plate respectively perpendicular to described first plate, in " U " font, on described second plate lateral surface while be simultaneously fixed with the 4th plate perpendicular to described first plate perpendicular to described second plate, the lateral surface of described 3rd plate is symmetrically arranged with the 5th plate with described 4th plate, described first plate, second plate, 3rd plate, 4th plate and the 5th plate are respectively equipped with screw hole.
Further, described first plate two screw holes have been horizontally disposed with.
Further, described first plate is provided with three screw holes, and three screw hole distributions triangular in shape.
Further, the centre position of described second plate, the 3rd plate, the 4th plate and the 5th plate is respectively equipped with a screw hole.
Further, between described second plate and the 4th plate, be provided with the first stiffener, between described 3rd plate and the 5th edition, be provided with the second stiffener.
The advantage that the utility model has and beneficial effect are: the first plate, the second plate and the 3rd plate form " U " font structure, can the middle vertical beam of the backrest of chair be fixed between " U " font structure, and fixed by screw, 4th plate and the 5th plate are then fixed with chair body respectively, so just backrest can be fixed in chair body firmly; Be provided with the first stiffener between second plate and the 4th plate, be provided with the second stiffener between the 3rd plate and the 5th plate, intensity can be improved further.
