Description

Technical Field

[0001] The utility model relates to a flipping device for a folding door, in particular to a flipping device which can improve the sealing performance of a folding cabinet door when the door is closed and can flexibly adjust the door opening angle. Background Art

[0002] In the market, cabinet doors are generally opened and closed in two ways: upward flipping and side flipping. Users can choose one of the two ways according to environmental requirements. If the size of the cabinet is designed to be greater in height than width, the upward flipping door will occupy more space when the cabinet door is flipped up and opened. In order to solve this problem, people generally use a multi-section folding door design to solve it. However, this type of cabinet door has a problem of insufficient sealing in the middle position of the cabinet door when closed due to long-term use or insufficient manufacturing of the middle hinge, making it easy for small domestic animals such as cockroaches to enter and exit the cabinet. This is a problem that users hope to be solved. Utility Model Content

[0003] The utility model aims to provide an upward turning device for a folding door, which uses a front pulley and a rear pulley as main movable connecting parts of the upward turning device, so that the upward turning device makes less noise when working, and at the same time, when the cabinet door is closed, the horizontal position of the shaft core of the front pulley is higher than the horizontal position of the shaft core of the rear pulley, so that the upward turning arm can retain a continuous door closing force after the cabinet door is closed, so that the cabinet door is more sealed when closed.

[0004] The technical solution of the utility model is based on a cabinet body, a cabinet door, a cabinet door hinge, and an upward flipping device, wherein the upward flipping device includes an outer shell, an upward flipping thrust device, a swing seat, a rear pulley, a door closing buffer, an angle adjustment seat, an adjustment screw, a door closing buffer seat, an upward flipping arm, a front pulley, and a door opening buffer. The utility model is characterized in that the tail of the upward flipping arm is hingedly mounted on the front end inside the outer shell, and the front pulley is arranged at the tail end of the upward flipping arm, the middle part of the swing seat is hinged with the middle part inside the outer shell, and a rear pulley is arranged at the middle part of the front side of the swing seat. When the cabinet door is opened and closed, the upward and downward swinging of the upward flipping arm can drive the front pulley and the rear pulley on the swing seat to contact each other, and can make the swing seat swing clockwise or counterclockwise. When the cabinet door is closed, the horizontal position of the shaft core of the front pulley in the outer shell is higher than the horizontal position of the shaft core of the rear pulley.

[0005] When the cabinet door is in a closed state, the horizontal position of the shaft core of the front pulley in the shell is 2 to 3 mm higher than that of the shaft core of the rear pulley, so that the swing seat, under the pushing action of the upward thrust device, enables the upward flip arm to retain a continuous door closing force, making the cabinet door more sealed when closed.

[0006] The utility model has a rear end of an upward flipping thrust device hinged to the shell at the rear end inside the shell, and a front end of the upward flipping thrust device hinged to the upper end of a swing seat, so as to provide the upward flipping device with power for opening and closing the door.

[0007] The utility model discloses a door opening buffer arranged at the front end top of the shell, located above the intersection of the front pulley and the rear pulley. When the cabinet door is opened to a set maximum door opening angle, the tail of the upper flip arm contacts the buffer rod at the front end of the door opening buffer, and the door opening buffer provides a door opening buffering force for the upper flip arm.

[0008] The utility model discloses a door closing buffer seat which can be movably arranged at the bottom of the front end of the shell body forward and backward and is located below the intersection of the front pulley and the rear pulley. The angle adjustment seat is arranged at the top of the door closing buffer seat. The adjusting screw is inserted into the angle adjustment seat from front to back for installation. The forward and reverse adjustment screws can make the tail end of the adjusting screw extend and retract inside and outside the tail of the angle adjustment seat. When the adjusting screw is extended at the tail of the angle adjustment seat, it can contact the lower end of the swing seat, thereby limiting the swing angle of the swing seat, thereby adjusting the opening angle of the cabinet door. The door closing buffer is arranged in the shell body and is located behind the door closing buffer seat, so as to provide a buffer force when the cabinet door is closed.

[0009] The working principle of the utility model is to use the front pulley of the upper flip arm and the rear pulley of the swing seat as the main active connecting parts of the upper flip device, so that the upper flip device makes less noise when working, and when the cabinet door is closed, the horizontal position of the shaft core of the front pulley is higher than the horizontal position of the shaft core of the rear pulley, so that the upper flip arm can retain a continuous door closing force after the cabinet door is closed, so that the cabinet door is more sealed when closed, and a door opening buffer and a door closing buffer seat that can move forward and backward are respectively arranged above and below the intersection of the front pulley and the rear pulley. A door closing buffer is designed behind the door closing buffer seat, so that the upper flip device obtains a buffering force when the door is opened and closed at the maximum and minimum angles, effectively solving the problem that the cabinet door switch is easily damaged, and at the same time, the swing angle of the swing seat can be flexibly adjusted by retracting the adjusting screw in the angle adjustment seat, so that the door opening angle of the upper flip arm can be flexibly adjusted between 83 and 100 degrees.

[0010] The utility model has the advantages of simple structure, stable and safe operation, low noise, good buffering effect of cabinet door opening and closing, and can effectively solve the problem of non-sealing of the folding upward cabinet door when it is closed.
