Description

Technical Field

[0001] The invention relates to the field of flip-up support structures, and in particular to a flip-up support with a random stop and adjustment function. Background Art

[0002] In furniture design, it is often seen that the cabinet is hung on the wall to make a wall cabinet, and some of these cabinets are equipped with doors that open upwards. When opening, external force acts on the door, and the door flips up, thereby opening the cabinet door. Early flip-up doors used door hinges to realize the door's rotation and flip-up functions, but they could not meet the requirement of whether the door could be stopped in a convenient position, because ordinary hinges could not support the weight of the door, and could not control the speed of the door falling, so the collision sound when closing the door could not be effectively eliminated. In order to solve these defects, flip-up supports began to be used. When opening the door, as the door flips up, its internal elastic mechanism begins to move, providing the door with a force to offset the weight of the door, so that the user can easily open the door; when closing the door, the flip-up support continues to provide support force, so the user only needs a small force to close the door. Some products also have a door closing buffer mechanism designed in the support, so that at the moment the door is closed, a damping force is provided to slow down the door's descent. This type of product solves some basic functional problems, but does not completely address users' desire for higher demands, and there are still many product defects that have not been resolved: for different door weights, the upward flip height when opening the door cannot be achieved within the reach of the user, and the door cannot be stopped at any position without suddenly falling and hitting the user's head; the maximum upward flip angle cannot be adjusted for different users; the product's support and buffer mechanism is relatively complex, reducing the usable space inside the cabinet; when the user installs it themselves, if there is a processing error, it is difficult to make the cabinet door and the cabinet body fit perfectly by adjusting the adjustment mechanism inside the product. Summary of the invention

[0003] The purpose of the present invention is to solve the problems existing in the background technology and to provide a flip-up support with a random stop adjustment function, which can stop a cabinet door at any position within a certain range and is convenient and quick to adjust and install.

[0009] Preferably, the flip bracket includes a fixed plate, a flip shaft, a connecting shaft and an adjusting slider; an arc plate is arranged at the bottom of the fixed plate, and a flip shaft sleeve is arranged on the arc plate; the flip shaft is rotatably arranged in the flip shaft sleeve, and the arc plate is rotatably connected to the top of the plastic handle through the flip shaft; the connecting shaft is rotatably arranged at the bottom of the arc plate, and the arc plate is rotatably connected to the top of the connecting plate through the connecting shaft; the adjusting slider is slidably arranged on the fixed plate, and an eccentric adjusting shaft for changing the position of the adjusting slider is arranged on the fixed plate, and the adjusting slider is connected to the door panel.

[0010] Preferably, it also includes a limiting plate and a positioning convex point; the limiting plate is rotatably arranged on the arc plate at the bottom of the fixed plate, and a waist-shaped hole for the flip axis to pass through is arranged on the limiting plate; the positioning convex point is arranged on the arc plate at the bottom of the fixed plate.

[0011] Preferably, when the door panel is opened upward to the maximum position, the angle between the flip bracket and the support handle is 108 degrees.

[0016] 2. The movement trajectory of the cabinet door is reasonable, which can protect the user's hands from being pinched, and it will not flip up too high, making it out of reach for short people.

[0017] 3. For users of different heights, the maximum upward flip angle can be adjusted, taking into account the problem of large height differences.

[0018] 4. The support and buffer mechanisms of the product have been optimized, making the product more compact and beautiful, thereby increasing the usable space inside the cabinet.

[0019] 5. When the user installs the cabinet by himself, if there is a processing error, the user can adjust the adjustment mechanism inside the product to make the cabinet door and the cabinet body fit more perfectly.

[0020] 6. In order to reduce the difficulty of installing the cabinet doors, a quick installation structure is designed. Because the wall cabinet is a certain height from the ground, it is still difficult for users who are not tall enough to install it on it. If it can be positioned well at the bottom, it can be quickly positioned during installation and only one fixing screw is needed. This saves effort and reduces the difficulty of installation.

[0021] 7. The cabinet door can be rotated and supported without adding other hinges to assist the rotation, making installation easier. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] like Figure 1-4 As shown, the flip-up support with the function of arbitrary stop adjustment proposed by the present invention comprises a support seat 1, a support handle 2, a flip bracket 3, a connecting assembly 4 and a tension spring 5; the support seat 1 comprises a seat plate 11, a seat plate rotating shaft 12 and an eccentric shaft 13; the support handle 2 comprises a plastic handle 21, a buffer cylinder 22 and a U-shaped slider 23; the connecting assembly 4 comprises a connecting plate 41 and a fixing column 42;

[0030] The plastic handle 21 is a U-shaped plate, the bottom of the plastic handle 21 is rotatably connected to the bottom of the support seat 1, the top of the plastic handle 21 is rotatably connected to the top of the flip bracket 3, a flat plate is arranged on the inner wall of the plastic handle 21, a support spring 25 is arranged on the flat plate, and the top of the support spring 25 is connected to the U-shaped slider 23; the U-shaped slider 23 is slidably arranged on the inner wall of the plastic handle 21 along the vertical direction, and a limiting hole for the top of the tension spring 5 to be inserted is arranged on the top of the U-shaped slider 23; the buffer cylinder 22 is arranged on the inner wall of the plastic handle 21 obliquely downward, and the buffer cylinder 22 is in contact with the support seat 1;

[0031] The seat plate rotating shaft 12 is arranged at the bottom of the seat plate 11, and a through hole for the seat plate rotating shaft 12 to pass through is arranged at the bottom of the plastic handle 21; the eccentric shaft 13 is arranged on the seat plate 11;

[0032] The connecting plate 41 is located in the U-shaped groove of the plastic handle 21, the top of the connecting plate 41 is rotatably connected to the top of the flip bracket 3, and the bottom of the connecting plate 41 is rotatably connected to the seat plate 11 through the eccentric shaft 13; an adjusting screw 43 is provided on the connecting plate 41; a fixing column 42 is sleeved on the adjusting screw 43; the top of the tension spring 5 is stuck in the limiting hole provided on the top of the U-shaped slider 23, and the bottom of the tension spring 5 is sleeved on the fixing column 42. When the door panel is opened upward to the maximum state, the angle between the flip bracket 3 and the support handle 2 is 108 degrees. When the angle between the flip bracket 3 and the support handle 2 is greater than 75 degrees, the door panel can be hovered at any position. The flip support is provided in two groups, including a left flip support and a right flip support, and the flip support and the right flip support are used in pairs.

[0033] In this embodiment, during installation, the support seat 1 is connected to the cabinet side panel, and the door panel is connected to the flip bracket 3. The maximum opening angle of the door body is 108 degrees. When the door is opened to an angle of more than 75 degrees, the door body can be stopped at will. At this time, the tension torque of the support spring 25 and the tension spring 5 of the flip support is almost equal to the rotation torque of the cabinet door, thereby achieving torque balance, the door is stationary, and hovering at any position within a certain angle is achieved. By adjusting the position of the eccentric shaft 13, the distance between the seat plate rotating shaft 12 of the support seat 1 and the connecting axis of the flip bracket 3 is changed, thereby changing the rotation angle of the flip bracket 3, and the adjustment of the closing angle of the door is achieved; by adjusting the screw 43, the angle between the plastic handle 21 and the cabinet side panel is changed, thereby adjusting the position between the cabinet door and the side panel, and realizing the left and right adjustment of the door panel. The buffer closing is mainly achieved by the buffer cylinder 22 in the support handle 2. When the door panel is close to the closed position, the buffer cylinder 22 and the seat plate 11 squeeze and start to compress, providing reverse pressure, and the door panel closing begins to slow down until the door panel slowly closes. The left and right upward flip supports provide the rotation and support force of the door body, so there is no need to add other rotating hinges.

A limiting ring is set on the lifting screw 24, and the bottom of the support spring 25 is in contact with the limiting ring.

[0036] In this embodiment, when the weight of the door changes, it is necessary to adjust the lifting screw 24 to change the position of the U-shaped slider, thereby changing the extension length of the tension spring 5, and then changing the tension torque of the tension spring 5 to enter a new torque balance. Even if the weight of the door changes, the door can still be suspended at an arbitrary position within a certain angle.
