[0002] The existing cabinet door flip-up support device is disclosed in the Chinese invention patent application (publication number CN116201432 A). When adjusting the supporting force of the flip-up support device, a hexagonal key is installed at the bottom of the device through the adjustment opening and the screw hole groove of the screw rod. The screw rod rotates to move the adjustment block in the length direction of the screw rod. The position of the elastic rear shell is adjusted by the inclined structure provided between the adjustment block and the elastic rear shell, and then the degree to which the elastic rear shell squeezes the thrust spring is adjusted to achieve the adjustment of the original thrust of the cabinet door. However, since the flip-up support device is installed close to the cabinet side panel, the rotation range of the hexagonal key at the bottom of the device is blocked and limited by the cabinet side panel. When adjusting, the hexagonal key must be repeatedly reset and multiple small rotation operations must be performed intermittently, which is inconvenient to adjust the supporting force of the device.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical concept to be protected by the present invention.

[0019] like Figures 1 to 7The upward flipping support device 100 shown is installed on the inner walls of the left and right side panels 201 of the cabinet body 200 and is connected to the folding door panel 300; the upper end of the folding door panel 300 is hinged to the cabinet body 200, and when the folding door panel 300 is opened upward to any angle between 45° and 100°, the upward flipping support device 100 can support the folding door panel 300 so that the folding door panel 300 is suspended, and the folding door panel 300 will not close downward by itself under the action of gravity.

[0020] The flip-up support device 100 includes an outer shell 1, which is fixed to the inner walls of the left and right side panels 201. A spring seat 2, a force transmission block 3 and a convex-concave wheel 4 are arranged in the outer shell 1, a spring 5 is arranged between the spring seat 2 and the force transmission block 3, a force-bearing roller 31 is arranged in front of the force transmission block 3, the convex-concave wheel 4 is connected to a support rod 6, a sliding rod 7 that can slide and retract is arranged in the support rod 6, the end of the sliding rod 7 is connected to a combined body base 8, and the combined body base 8 is connected to the folding door panel 300. After the folding door panel 300 is flipped up and folded, the force-bearing roller 31 presses against the side of the convex-concave wheel 4 under the elastic force of the spring 5, so that the folding door panel 300 is freely suspended after being opened more than 45°.

[0021] A first inclined surface structure 21 is provided at the rear of the spring seat 2, and an adjustment bracket 9 is installed in the outer shell 1 at the rear of the spring seat 2. An adjustment screw 10 with a vertical central axis is pivotally provided on the adjustment bracket 9, and a slider 11 is threadedly provided on the adjustment screw 10. The slider 11 is provided with a second inclined surface structure 111 facing the spring seat 2, and the second inclined surface structure 111 is closely attached to the first inclined surface structure 21. An assembly hole 91 is provided at the lower end of the adjustment bracket 9, and an adjustment nut 12 is assembled on the assembly hole 91. The central axis of the adjustment nut 12 is perpendicular to the side wall surface of the outer shell 1, that is, perpendicular to the plate surface of the left and right side plates 201. A first pivoting portion 123 is provided at one end of the adjustment nut 12, and a second pivoting portion 124 is provided at the other end. The first pivoting portion 123 is pivotally mounted on the outer shell 1, and the second pivoting portion 124 is pivotally mounted on the assembly hole 91, so that the adjustment nut 12 can be rotated and adjusted.

[0022] The lower end of the adjusting screw 10 is coaxially provided with a face gear 101, and the adjusting nut 12 is provided with a cylindrical gear 121, and the cylindrical gear 121 and the face gear 101 are meshed for transmission. During specific assembly, a limit stop wall 125 is provided on the inner side of the first pivoting portion 123, and the limit stop wall 125 is in contact with the inner wall of the outer shell 1, and the end face of the cylindrical gear 121 away from the limit stop wall 125 is in contact with the side wall of the adjusting bracket 9, which can prevent the adjusting nut 12 from moving in the direction of the central axis of the adjusting nut 12 during the rotation adjustment process, and further ensure the stability of the rotation adjustment of the adjusting nut 12.

[0023] The flip-up support device 100 is adapted for installation with the cabinet door. If a heavy door is adapted for installation, the folding door panel 300 cannot hover when opened more than 45°, and the supporting strength of the flip-up support device 100 needs to be increased. The adjusting nut 12 is rotated to make the adjusting screw 10 rotate clockwise on the adjusting bracket 9 through the transmission between the cylindrical gear 121 and the face gear 101. The slider 11 descends along the adjusting screw 10 and acts on the first inclined surface structure 21 through the second inclined surface structure 111 to push the spring seat 2 toward the force transmission block 3. The compression amount of the spring 5 increases, and the thrust of the spring 5 on the force transmission block 3 increases, thereby increasing the supporting force when the force roller 31 presses against the side of the convex and concave wheel 4, so that the flip-up support device 100 is suitable for the hovering support of the heavy door.

[0024] If it is suitable for installing a small door with light weight, the folding door panel 300 is opened more than 45°, and the folding door panel 300 is automatically bounced upwards. It is necessary to reduce the supporting force of the upward flipping support device 100, and the adjusting nut 12 is rotated to make the adjusting screw 10 rotate counterclockwise on the adjusting bracket 9 through the transmission between the cylindrical gear 121 and the face gear 101. The slider 11 rises along the adjusting screw 10, and the spring seat 2 moves toward the adjusting screw 10. The compression amount of the spring 5 is reduced, and the thrust of the spring 5 on the force transmission block 3 is reduced, thereby reducing the supporting force when the force roller 31 is pressed against the side of the convex and concave wheel 4, so that the upward flipping support device 100 is suitable for the hovering support of a small door with light weight.

[0025] An adjustment groove 122 is provided on the end face of the second pivot portion 124, and an adjustment hole 13 is provided on the shell side wall of the outer shell 1. The adjustment groove 122 is provided corresponding to the adjustment hole 13 and is located inside the outer shell 1, or the second pivot portion 124 of the adjusting nut 12 is extended so that the adjustment groove 122 is provided in the adjustment hole 13, or the second pivot portion 124 of the adjusting nut 12 passes through the adjustment hole 13 so that the adjustment groove 122 protrudes from the shell side wall of the outer shell 1. In the cabinet, the adjusting nut 12 is rotated by acting on the adjustment groove 122 from the side of the flip-up support device 100 through a tool such as a wrench. The rotation adjustment of the adjusting nut 12 by the wrench will not be blocked or restricted by the side panel of the cabinet, and the wrench can be continuously rotated counterclockwise or clockwise, so that the supporting force adjustment of the flip-up support device 100 is smoother and more convenient.

[0026] By setting an adjusting nut 12 whose central axis is orthogonal to the axis of the adjusting screw 10, a wrench acts on the adjusting nut 12 to drive the adjusting screw 10 to rotate, and the adjusting operation position of the wrench on the supporting device is changed, so that the supporting force can be easily adjusted. At the same time, the cylindrical gear 121 and the face gear 101 transmission structure used between the adjusting nut 12 and the adjusting screw 10 can achieve a 90° change in the transmission route. The transmission structure is simple, the transmission efficiency and precision of controlling the lifting and lowering activities of the adjusting slider 11 are high, the stability is high, and it is conducive to simplifying the adjustment work during gear installation and assembly.

[0027] like Figure 8As shown, the assembly hole 91 is omitted on the adjustment bracket 9, so that the adjustment nut 12 is directly pivotally mounted on the outer shell 1 through the first pivot portion 123 and the second pivot portion 124, which can further simplify the setting of the adjustment bracket 9 and the assembly setting structure of the adjustment nut 12.

[0028] In another embodiment, Fig. 9 As shown, the lifting and lowering of the slider 11 and the activity adjustment of the spring seat 2 are as follows: the adjusting nut 12 is rotated to make the adjusting screw 10 rotate clockwise on the adjusting bracket 9 through the transmission between the two gear structures, the slider 11 descends along the adjusting screw 10, the spring seat 2 moves toward the adjusting screw 10, the compression amount of the spring 5 is reduced, the thrust of the spring 5 on the force transmission block 3 is reduced, and the supporting force of the force roller 31 when it presses against the side of the convex and concave wheel 4 is reduced;

[0029] Rotating the adjusting nut 12 causes the adjusting screw 10 to rotate counterclockwise on the adjusting bracket 9 through the transmission between the two gear structures, and the slider 11 rises along the adjusting screw 10. The slider 11 acts on the first inclined surface structure 21 through the second inclined surface structure 111 to push the spring seat 2 toward the force transmission block 3. The compression amount of the spring 5 increases, and the thrust of the spring 5 on the force transmission block 3 increases, thereby increasing the supporting force of the force roller 31 when it presses against the side of the convex and concave wheel 4.

[0030] Fig. 9 In the embodiment, although the corresponding relationship between the rotation direction of the adjusting screw 10 and the activity direction of the spring seat 2 is Figures 1 to 7 Although the embodiments are different, the effects of adjusting the supporting force of the flip-up supporting device 100 are consistent.

[0031] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the utility model.
