The specific embodiment

In order better to understand the utility model, the utility model will be further described below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the described scope of embodiment.

Referring to Fig. 1, in the present embodiment, hydraulicefficiency hinge comprises Connection Block 1, pivoted arm 2, the mount pad 4 that is connected with pivoted arm 2 and is arranged on the interior snubber 6 of pivoted arm.Wherein the structure of Connection Block 1, pivoted arm 2 and connecting rod 3 is respectively as Fig. 2, Fig. 3, shown in Figure 4.

Connection Block 1 flexibly connects by a connecting rod 3 with pivoted arm 2, connecting rod 3 one ends and Connection Block 1 are hinged by connecting axle, the other end and pivoted arm 2 are hinged by another connecting axle, this connecting axle is provided with torsion spring 8, these torsion spring 8 one ends are taken and are placed in the pivoted arm, the other end is arranged in the described connecting rod 3, and the torsion by torsion spring can compress Connection Block 1 and pivoted arm 2, makes it be in open mode.

Connection Block 1 is provided with the cavity that adapts with connecting rod 3 sizes, and when connecting rod 3 drove pivoted arm 2 rotations, connecting rod 3 can stretch into this cavity.

Snubber 6 comprises piston rod and cylinder body, and this snubber 6 is connected with Connection Block 1 by a transmission device 5.

As Fig. 5, shown in Figure 6, transmission device 5 comprises first driving member 51, two connection straps 53, second driving member 52.First driving member 51 is made up of some driver blades, and it is hinged that itself and second driving member 52 pass through connector 53.

First driving member, 51 both sides are connected with a metal fastenings 7 respectively, and the front view of this metal fastenings 7 and lateral view are seen Fig. 7, Fig. 8.These metal fastenings 7 one ends are connected with an end and the Connection Block 1 of first driving member 51, the other end is connected with the other end and the pivoted arm 2 of first driving member 51, this link is outwards expanded, form projection, the end of this projection contacts, pushes with the inwall of pivoted arm 2, play fastening effect, this kind securing member is owing to adopt metal to make, goods than other materials, it is strong to have bearing, the advantage of not fragile, long service life, and this also makes hydraulicefficiency hinge that this securing member is installed, can bear bigger cabinet door gravity, long service life.。

The piston rod of second driving member, 52 1 ends and snubber 6 stretches out cylinder body end and flexibly connects by a connecting axle, and the other end is connected with the sidewall of described pivoted arm 2.

The course of work of hydraulicefficiency hinge is as follows in the present embodiment:

Connection Block is installed on the cabinet door, and mount pad is installed on the cabinet; When opening the cabinet door, to the cabinet door application of force, the connecting rod that is positioned at the Connection Block cavity clockwise rotates around connecting axle, driving hinged with it pivoted arm stretches out to Connection Block cavity outside gradually, first driving member hinged with Connection Block also rotates thereupon, and drive second driving member and rotate, the axle that is connected with piston rod on second driving member rotates and drives piston rod and stretches into to cylinder interior, the one-way valve opens of establishing in the cylinder body, piston rod moves under the situation of flowed friction not having, and snubber does not play cushioning effect, under the acting in conjunction of torsion spring, the Connection Block fast rotational makes the cabinet door finish opening action fast.

During closure cabinet door, the cabinet door is imposed external force, torsion spring acts on connecting rod and pivoted arm, connecting rod rotates in the counterclockwise direction, driving hinged with it pivoted arm stretches in the cavity of Connection Block gradually, and first driving member that with pivoted arm be connected hinged with Connection Block also rotates thereupon, second driving member that is connected with first driving member also rotates thereupon, the axle that is connected with piston rod on second driving member rotate and the pulling piston rod protruding in the snubber cylinder body, snubber plays cushioning effect, under the acting in conjunction of torsion spring, Connection Block slowly rotates, and the cabinet door slowly closes.

More than hydraulicefficiency hinge provided by the utility model is described in detail.It is to be noted; the described content of the specific embodiment be for better implement the utility model preferred embodiment; protection domain of the present utility model is not limited to the described technical scheme of above-mentioned embodiment; and should be as the criterion with the described flesh and blood of claims, any possible improvement is only otherwise the flesh and blood that breaks away from the utility model claim all belongs to the scope that the utility model is protected.
