Description
Technical Field
The utility model relates to a hardware fitting specifically is a world hinge with buffering reset function.
Background
Hinges are mechanical devices used to connect two solid bodies and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material.
Cabinets such as wardrobes, cabinets and the like are provided with openable cabinet doors. The conventional hinge for connecting a cabinet body and a cabinet door has the following problems: because the cabinet door does not have or cannot provide enough cabinet door closing force, gaps or rebounds exist after the cabinet door is closed; or, because cabinet door closing force is too big, the cabinet door closing process is too fast, leads to the cabinet door striking cabinet body to send the noise, and this can lead to the cupboard to damage even in the past.
Therefore, there is a need for a connection device that provides adequate closing force and that provides a moderate and smooth closing speed.

The utility model discloses the purpose is realized with following mode: the utility model provides a world hinge with buffering reset function, its includes hinge box and hinge cup, and the articulated first hinge arm and second hinge arm of installing in the hinge box, the first hinge arm and second hinge arm other end and the articulated installation of hinge cup, first hinge arm and second hinge arm are around the hinge point swing in hinge box and the hinge cup, realize the switching between hinge cup and the hinge box, its characterized in that: the hinge box is characterized in that one end, hinged to the hinge box, of the first hinge arm extends downwards to form a damping arm, a driving arm extends towards the side wall of the hinge box, a guide wheel driven by a spring is arranged in the hinge box and presses the driving arm to push the first hinge arm to move towards the closing direction all the time, the damping arm extends downwards to enter a damping groove in the hinge box, a damping oil cylinder is arranged in the damping groove, and the damping arm is in contact with the damping oil cylinder and drives the damping oil cylinder to move.
The hinge box in be provided with the spring groove, the guide pulley frame is installed to spring inslot slidingtype, and the leading wheel is fixed at the front end of guide pulley frame, and the spring is installed to the afterbody of guide pulley frame, and the spring promotes the guide pulley frame and moves to first hinge arm direction all the time.
The spring groove is arranged obliquely upwards.
The damping oil cylinder is a compression damping type oil cylinder, and the cylinder body part of the damping oil cylinder is installed towards the direction of the damping arm.
The driving arms are arranged on the side walls of the first hinged arm and the damping arm and are distributed in a T shape.
The first hinged arm, the damping arm and the driving arm are integrally made of metal plates.
The utility model has the advantages that: 1. simple structure, low production cost and improved market competitiveness. 2. The thrust that the spring produced can be after the hinge closes certain angle, promotes the hinge automatically and closes to be favorable to keeping the leakproofness of cabinet door. 3. In the closing process of the hinge, the damping cylinder is used for damping the closing speed of the hinge, so that the hinge is closed more stably and quietly. 4. First hinge arm is direct and the cushion cylinder contact through the damping arm that its afterbody extends for connect between the two simply, and the effort is more direct, improves its work efficiency. 5. The contact surface between the damping arm and the buffer changes along with the closing angle of the hinge, and the length of the stressed lever is gradually lengthened, so that the requirement of acceleration on the change of damping force when the hinge is closed is balanced, and the hinge is closed more stably.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a world hinge with buffering reset function, its includes hinge box 1 and hinge cup 2, and the articulated first hinge arm 3 and the second hinge arm 4 of installing in the hinge box 1, the first hinge arm 3 and the 4 other ends of second hinge arm and the articulated installation of hinge cup 2, first hinge arm 3 and second hinge arm 4 are around the hinge point swing in hinge box 1 and the hinge cup 2, realize the switching between hinge cup 2 and the hinge box 1, its characterized in that: one end of the first hinge arm 3, which is hinged with the hinge box 1, extends downwards to form a damping arm 5, a driving arm 6 extends towards the side wall of the first hinge arm, a guide wheel 8 driven by a spring 7 is arranged in the hinge box 1 and pressed in the driving arm 6 to push the first hinge arm 3 to move towards the closing direction all the time, the damping arm 5 extends downwards to enter a damping groove 9 in the hinge box 1, a damping oil cylinder 10 is arranged in the damping groove 9, and the damping arm 5 is in contact with the damping oil cylinder 10 and drives the damping oil cylinder 10 to move.
The hinge box 1 is internally provided with a spring groove 11, a guide wheel frame 12 is arranged in the spring groove 11 in a sliding manner, a guide wheel 8 is fixed at the front end of the guide wheel frame 12, a spring 7 is arranged at the tail part of the guide wheel frame 12, and the spring 7 pushes the guide wheel frame 12 to move towards the first hinged arm 3 all the time.
The groove of the spring 7 is arranged obliquely upwards.
The damping cylinder 10 is a compression damping type cylinder, and the cylinder body part of the cylinder is installed towards the direction of the damping arm 5.
The driving arms 6 are arranged on the side walls of the first hinged arm 3 and the damping arm 5 and are distributed in a T shape.
The first hinged arm 3, the damping arm 5 and the driving arm 6 are integrally made of metal plates.
The working principle is as follows: as shown in fig. 3-4, when the hinge is closed, the hinged point of the first hinge arm and the second hinge arm hinged to the hinge cup swings towards the direction of the hinge box, so that the tail of the first hinge arm swings towards the direction of the damping oil cylinder, and damping power is generated by using the extrusion between the damping arm and the damping oil cylinder to slow down the swing speed of the first swing arm, thereby playing a speed damping role when the hinge is closed, and making the hinge more stable in closing. When the hinge is closed to a certain angle, the guide wheel pushed by the spring pushes the driving arm on the first hinge arm to move to generate power for closing the hinge, so that the hinge is automatically closed when the closing angle of the hinge is smaller than a set value, and the hinge is automatically opened when the closing angle of the hinge is larger than the set value.
Wherein, because the damping arm that first hinge arm in this case extends through its afterbody is direct and the buffer cylinder contact, and the actuating arm and the spring support guide pulley direct contact that first hinge arm curb plate extends for connect between the three simply, and the effort is more direct, improves its work efficiency, has also simplified the inside structure of hinge box, has abandoned complicated link structure, makes hinge work more smooth, in reduction in production cost, prolongs its life.
Further: because unique design in the present case for contact point between damping arm and the damping hydro-cylinder can change at the hinge in-process of closing, close the angle when the hinge big more, the lever length of damping arm also can be big more, thereby produce the damping dynamics on first hinge arm and also increase gradually, thereby acceleration when balanced hinge is closed, make the hinge closing speed more steady, thereby when having avoided the tradition to change into merit hinge and close, speed is more and more fast, lead to closing the drawback that the noise is big, so can extensively use widely.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
