A few days ago, a large amount of hydraulicefficiency hinges that use connect door leaf in furniture such as wardrobe or file cabinet, can cushion the impact force of door leaf when closing, and reduce and close the sound that door sends, the application life of also improving wardrobe or file cabinet.

Hydraulicefficiency hinge mainly is made up of door leaf mount pad, swing arm, doorframe mount pad, hydraulic cylinder, shell fragment and STATEMENT OF FEDERALLY SPONSORED, the axis hole that on shell fragment, is respectively equipped with the axis hole that is connected with the door leaf mount pad, the axis hole that is connected with swing arm and is connected with STATEMENT OF FEDERALLY SPONSORED, shell fragment is articulated and connected by described axis hole and corresponding bearing pin and door leaf mount pad, swing arm and STATEMENT OF FEDERALLY SPONSORED respectively, and STATEMENT OF FEDERALLY SPONSORED is articulated and connected by bearing pin and hydraulic cylinder again.

In hydraulicefficiency hinge, shell fragment is a critical component, and its mechanical performance will directly influence the application life of hydraulicefficiency hinge.Shell fragment in the common hydraulicefficiency hinge is made (as shown in Figure 7) by the whole punching press of steel disc, owing to be subjected to the influence of material and technology, the elasticity of the shell fragment in the common hydraulicefficiency hinge is difficult to satisfy uses upward requirement, at described problem, in order to improve the elasticity of shell fragment, people adopt stacked structure to make shell fragment, to improve the elasticity of hydraulicefficiency hinge shell fragment, still, the shortcoming of stacked shell fragment is a waste material, take a lot of work, production efficiency is low, the cost height.

In addition, existing STATEMENT OF FEDERALLY SPONSORED is single-piece, and the single-piece STATEMENT OF FEDERALLY SPONSORED has advantages of simple structure and simple, but its shortcoming is to make the pendulum angle between swing arm and the door leaf mount pad less than normal, make hydraulicefficiency hinge need when mounted cushion block is set on doorframe, both increased installation difficulty, also influence attractive in appearance.

Summary of the invention:

The purpose of this utility model is the improvement to existing hydraulicefficiency hinge, at first is the improvement to the whole punching type shell fragment of steel disc, provides that a kind of production efficiency height, cost are low, the shell fragment of good springiness; Next is the improvement to STATEMENT OF FEDERALLY SPONSORED, increasing the pendulum angle between swing arm and the door leaf mount pad, thereby satisfies the use and the installation requirement of hydraulicefficiency hinge.

The realization of first purpose of the utility model is that punching press is provided with reinforcing rib on the basis of the whole punching type shell fragment of existing steel disc.Described reinforcing rib can be one or more, and the width a of reinforcing rib can be 2.5-3.5mm, and height b can be 0.5-1.0mm.

The realization of second purpose of the utility model is to change existing single-piece STATEMENT OF FEDERALLY SPONSORED into the combined type STATEMENT OF FEDERALLY SPONSORED.The combined type STATEMENT OF FEDERALLY SPONSORED is made up of triangle connector and in-line connector, the in-line connector is provided with two pin-and-holes, the triangle connector is provided with three pin-and-holes, triangle connector and in-line connector are articulated and connected by bearing pin, the triangle connector is articulated and connected on swing arm by bearing pin, pin-and-hole other on the in-line connector is articulated and connected by bearing pin and shell fragment, and pin-and-hole other on the triangle connector is articulated and connected by bearing pin and hydraulic cylinder.

The utility model has simple in structure, easy to process, advantages such as cost is low, good springiness, the requirement that can satisfy the installation of hydraulicefficiency hinge and use.
