[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] According to the attached Figures 1 to 4 As shown, the furniture hinge device capable of carrying a wide range of loads of the present invention comprises a housing 1 installed on a cabinet body and a fixing plate 2 installed on a door panel. A connecting rod assembly is provided between the housing 1 and the fixing plate 2, and a lever assembly and a power assembly for linking the connecting rod assembly are provided on the housing 1. The fixing plate 2 is installed at the swing end of the connecting rod assembly, the positioning end of the lever assembly is axially connected to the side plate of the housing 1, and the upper swing end of the lever assembly is slidably connected to the positioning end of the connecting rod assembly.

[0027] The power assembly includes a main auxiliary spring 3 and an auxiliary spring 4. The positioning ends of the main auxiliary spring 3 and the auxiliary spring 4 are respectively installed on the lower swing end of the lever assembly from bottom to top, and the connecting ends of the main auxiliary spring 3 and the auxiliary spring 4 are respectively provided with an adjustment assembly 5 for adjusting the working length to adjust the magnitude of the force, and the positioning part of the adjustment assembly 5 is fixed on the side plate of the housing 1, and the adjustment part of the adjustment assembly 5 is respectively rotatably connected to its fixed part and connected to the adjustment end of the main auxiliary spring 3 and the auxiliary spring 4.

[0028] In this way, on the basis that the lever assembly is non-adjustable, the magnitude of the force can be adjusted by adjusting the working length of the spring by adjusting the adjustment assembly 5 separately arranged at the adjustment end of the main auxiliary spring 3 and the auxiliary spring 4. The adjustment is simple and easy to implement.

[0029] Reference Figures 1 to 4 As shown, in further detail, the adjustment assembly 5 includes an adjustment limit block 51 and an adjustment bolt 52. The adjustment limit block 51 is installed on the side plate of the housing 1, and the adjustment bolt 52 is rotatably connected to the adjustment limit block 51 and is threadedly connected to the main auxiliary spring 3 and the auxiliary spring 4 respectively.

[0030] Furthermore, the positioning ends of the main auxiliary spring 3 and the auxiliary spring 4 are buckled on the lower swing end of the lever assembly, and the connecting ends of the main auxiliary spring 3 and the auxiliary spring 4 are respectively installed with clamping blocks 7 for threaded connection with the adjusting bolt 52.

[0031] Moreover, the clamping block 7 is provided with a buckle block 8 , the connecting ends of the main auxiliary spring 3 and the auxiliary spring 4 are buckled on the buckle block 8 respectively, and the adjusting bolt 52 is threadedly connected to the buckle block 8 .

[0032] In the optimized solution, a guide block 6 is provided on the outer side of the clamping block 7 , and a side plate of the housing 1 is provided with a guide groove 9 slidably connected to the guide block 6 .

[0033] That is, without adjusting the length of the main auxiliary spring 3 and the auxiliary spring 4, the load capacity of the hinge is fixed. Only when the adjusting bolt 52 is rotated, the clamping block 7 moves left and right with the rotation of the adjusting bolt 52, and the load capacity of the hinge is changed when the length of the main auxiliary spring 3 and the auxiliary spring 4 is changed. At the same time, the guide block 6 slides along the guide groove 9, prompting the clamping block 7 to slide in a directional manner on the side plate of the housing 1. The structure is stable, the operation is stable, the adjustment is simple, and it is easy to implement.

[0034] Meanwhile, the connecting rod assembly includes a first connecting rod 10, a second connecting rod 11, a third connecting rod 12, a fourth connecting rod 13, and a fifth connecting rod 14. The fixing plate 2 is installed at the swing end of the first connecting rod 10, the connecting end of the first connecting rod 10 is respectively connected to the swing ends of the second connecting rod 11 and the third connecting rod 12, the connecting end of the second connecting rod 11 is connected to the swing end of the fourth connecting rod 13, the connecting end of the fourth connecting rod 13 is connected to the side plate of the housing 1, the connecting end of the third connecting rod 12 is connected to the swing end of the fifth connecting rod 14, and the connecting end of the fifth connecting rod 14 is connected to the side plate of the housing 1. In addition, the swing end of the fifth connecting rod 14 is provided with an arc surface 141 for sliding connection with the lever assembly.

[0035] In addition, the lever assembly includes a bearing 15 and a lever member 16. The angular axis of the lever member 16 is connected to the side plate of the housing 1, the upper swing end of the lever member 16 is installed with a bearing 15, the bearing 15 is slidably connected to the fifth connecting rod 14 of the connecting rod assembly, and the lower swing end of the lever member 16 is buckled with the main auxiliary spring 3 and the auxiliary spring 4 of the power assembly from bottom to top.

[0036] Since the main auxiliary spring 3 and the auxiliary spring 4 are installed at different distances from the lever member 16 and the pivot point of the lever member 16, the auxiliary spring 4 is short from the pivot point of the lever member 16 and has a short fixed force arm, while the main auxiliary spring 3 is long from the pivot point and has a long fixed force arm, so that different effects are produced when the same spring length is changed, thereby achieving the goal of adjusting the load size of the hinge.

[0037] Reference Figures 1 to 4 As shown, the shell 1 is provided with a door opening damping assembly 17, and the door opening damping assembly 17 is installed at the upper end of the side plate of the shell 1, and the fifth connecting rod 14 of the connecting rod assembly is provided with an inclined groove 142 for touching or separating with the damping rod of the door opening damping assembly 17 as it swings.

[0038] Moreover, the connecting rod assembly is provided with a door closing damping assembly 18 , which is mounted on the second connecting rod 11 of the connecting rod assembly, and the damping rod of the door closing damping assembly 18 touches or separates from the fourth connecting rod 13 as the fixing plate 2 swings.

[0039] When the door panel is opened, the fixed plate 2 swings with the door panel to drive the first connecting rod 10, the second connecting rod 11, the third connecting rod 12, the fourth connecting rod 13, and the fifth connecting rod 14 to swing outwards respectively. As the fifth connecting rod 14 swings, the inclined slot 142 gradually contacts the damping rod of the door closing damping assembly 18, and under the damping action of the door closing damping assembly 18, the outward swinging speed of the fifth connecting rod 14 is slowed down to achieve door opening buffering.

[0040] When the door panel is closed, the fixed plate 2 is closed toward the housing 1 under the elastic action of the main auxiliary spring 3 and the auxiliary spring 4. When the second connecting rod 11 is folded toward the fourth connecting rod 13, the door closing damping assembly 18 contacts the fourth connecting rod 13 as the second connecting rod 11 swings, and under the damping action of the door opening damping assembly 17, the folding speed of the second connecting rod 11 toward the fourth connecting rod 13 is slowed down, thereby achieving door closing buffering.

[0041] In this way, with the structure of the door opening damping assembly 17 and the door closing damping assembly 18, the hinge can be effectively buffered during use, thereby improving the hinge performance and ensuring the quality of product use.

[0042] The above-mentioned specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the furniture hinge device capable of being used for a wide range of loads of the present invention is within the protection scope of the present invention.
