DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0018] A cabinet door hinge includes a fixed component 1 and a movable component 2. The fixed component 1 is used to be fixed on the cabinet body, and the movable component 2 is fixed to the cabinet door. The movable component 2 is hinged to the fixed component 1. The fixed component 1 and the movable component 2 are the hinge structures commonly used for cabinet doors. For example, they are the combination of the fixed part and the movable part in the Chinese invention patent with the authorized announcement number of "CN107109882B". That is, the fixed part is the fixed component 1 in the present application, and the movable part is the movable component 2 in the present application. A buffer component 3 is arranged between the fixed component 1 and the movable component 2. Only when the cabinet door rotates to be closer to the cabinet body will it drive the buffer component 3 to act, so as to slow down the movement of the cabinet door. That is, the slow-down action of the cabinet door only takes effect when the cabinet door is close to the cabinet body, which can not only take into account the closing speed but also buffer the cabinet door, reduce the possibility of hard contact between the cabinet door and the cabinet body, and extend the service life of the cabinet door and the cabinet body.

[0019] The buffer component 3 includes a trigger part 31 and a buffer part 32. The trigger part 31 and the buffer part 32 are respectively arranged on the movable component 2. When the cabinet door rotates, the trigger part 31 abuts against the cabinet door and is pushed to rotate by the cabinet door, and the trigger part 31 pushes the buffer part 32 to act. The trigger part 31 includes a push rod 311, a transmission wheel 312 and a pushing member 313. The push rod 311 is rotatably connected to the movable component 2, and the transmission wheel 312 is arranged at the end of the push rod 311 and rotates coaxially with the push rod 311. When the cabinet door rotates, the cabinet door abuts against the push rod 311 and drives the push rod 311 to rotate. The pushing member 313 fits on the movable component 2. An arc-shaped waist hole is provided on the pushing member 313, and a protrusion is provided on the end face of the transmission wheel 312 facing the pushing member 313. The protrusion is inserted into the arc-shaped waist hole. When the transmission wheel 312 rotates, the protrusion drives the pushing member 313 to reciprocate. The transmission wheel 312 can be a cam, any special-shaped wheel or a wheel with a regular shape. Specifically, when the cabinet door rotates and does not contact the push rod 311, the cabinet door can move freely when the push rod 311 does not contact the cabinet door. Taking the closing of the cabinet door as an example, the cabinet door can be quickly closed by pushing the cabinet door, and after the cabinet door contacts the push rod 311, it can drive the buffer part 32 to act. That is, the push rod 311 rotates, and then pushes the pushing member 313 to move. The pushing member 313 can be a stamping plate. The rotation of the cabinet door drives the transmission wheel 312 to rotate, and then the protrusion on the rotating wheel slides in the arc-shaped waist hole, driving the pushing member 313 to move. The pushing member 313 contacts the buffer part 32, and the movement of the pushing member 313 pushes the buffer part 32 to act. The buffer part 32 absorbs a large amount of kinetic energy, thus being able to slow down the closing speed of the cabinet door. That is, the slow-down action of the cabinet door only takes effect when the cabinet door is close to the cabinet body, which can not only take into account the closing speed but also buffer the cabinet door, reduce the possibility of hard contact between the cabinet door and the cabinet body, and extend the service life of the cabinet door and the cabinet body.

[0020] The buffer part 32 includes a linear speed reducer 321. The linear speed reducer 321 is arranged on the moving component 2 and abuts against the linear speed reducer 321 when the pushing member 313 moves, pushing the linear speed reducer 321 to move. The linear speed reducer 321 can be a small oil / cylinder. By using the telescopic movement of the cylinder to reduce the kinetic energy of the cabinet door, it can play a buffering role in closing the cabinet door, reduce the possibility of hard contact between the cabinet door and the cabinet body, and extend the service life of the cabinet door and the cabinet body.

[0021] A spring can also be arranged between the pushing member 313 and the moving component 2. One end of the spring abuts against the moving component 2, and the other end of the spring abuts against the pushing member 313. The movement of the pushing member 313 drives the spring to reciprocate telescopically. The moving component 2 includes a bottom shell 21. An installation hole 22 for installing the triggering part 31 is provided on the bottom shell 21. An installation groove 23 for accommodating the spring is provided on the bottom shell 21. The installation groove 23 is located on one side of the installation hole 22. A relief hole is provided on the side wall of the installation hole 22. The end of the push rod 311 passes through the relief hole and is fixedly coaxially connected with the transmission wheel 312, driving the transmission wheel 312 to rotate. By using the telescopic action of the spring, the pushing member 313 can be driven to quickly reset, thereby realizing the function of assisting in opening the cabinet door, and making the opening and closing of the cabinet door easier.

[0022] Compared with the prior art, when the cabinet door of the present utility model is closed, it directly pushes the cabinet door to rotate, and only when the cabinet door rotates to be relatively close to the cabinet body will the push rod 311 be pushed. Then, the linear buffer is driven to act by the action of the push rod 311 to slow down the movement of the cabinet door, that is, the slow-down action of the cabinet door only takes effect when the cabinet door is close to the cabinet body. It can not only take into account the closing speed but also play a buffering role for the cabinet door, reduce the possibility of hard contact between the cabinet door and the cabinet body, and extend the service life of the cabinet door and the cabinet body.

[0023] The above-mentioned embodiments are only the preferred embodiments of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope of protection required by the present utility model.
