[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] According to the attached Figures 1 to 5As shown, the furniture driving and operating device for adjusting loads in a wide range of the present invention includes a driving device for moving the door panels of furniture, and the driving device includes a driving base 1 installed on the cabinet, a connecting rod assembly 2 for rotating the door panels, a spring assembly 3 for providing power, and an adjusting mechanism 4 for adjusting the output. The adjusting mechanism 4 is rotated on the driving base 1 through a positioning rivet 5, and the adjusting mechanism 4 is formed with an upper lever part b and a lower lever part a that swing in a lever-like manner with the positioning rivet 5 as the axis point. The top of the upper lever part b is connected to the connecting rod assembly 2, and the adjusting mechanism 4 is provided with a slider 6 for adjusting the length of the lower lever part a, and the slider 6 is slidably connected to the lower part of the lower lever part a. One end of the spring assembly 3 is positioned and connected to the driving base 1, and the other end is rotatably connected to the slider 6.

[0029] By adjusting the position of the slider 6, the length of the lower lever part a can be adjusted, thereby adjusting the lever force ratio of the upper lever part b to the lower lever part a in the adjustment mechanism 4 to change the output force of the spring assembly 3 to meet the load changes of different door panels. The operation is simple and the applicability is strong.

[0030] Reference Figures 1 to 3 As shown, in further detail, the adjustment mechanism 4 includes a force arm 41, a support block 42, a ratchet 43, and a moving shaft 44. The force arm 41 is rotatably connected to the driving base 1 through a positioning rivet 5, the top of the force arm 41 is connected to the connecting rod assembly 2, the lower part of the force arm 41 is installed with a support block 42, the ratchet 43 is rotatably connected to the support block 42, the moving shaft 44 is threadedly connected to the ratchet 43, the ratchet 43 rotates to drive the moving shaft 44 to move forward and backward, and the slider 6 is installed on the moving shaft 44 and moves forward and backward accordingly with the moving shaft 44. That is, the slider 6 is installed on the moving shaft 44, the slider 6 and the moving shaft 44 can rotate with each other but cannot move, and can move with the movement of the moving shaft 44. The spring assembly 3 can rotate correspondingly on the slider 6. The connection structure is simple and the stability is high.

[0031] During this time, the support block 42 is provided with a positioning slot 45, and the end of the ratchet 43 is clamped on the positioning slot 45. The support block 42 is installed at the lower part of the arm 41 through the mounting pin 46; the arm 41 is installed with a limit pin 47 for directional rotation of the ratchet 43, and the limit pin 47 is installed on the arm 41 between the ratchet 43 and the slider 6. Prevent the ratchet 43 from loosening, improve the structural stability, and ensure the load performance of the door panel adjustment.

[0032] Since the ratchet 43 is limited by the support block 42 and the limit pin 47 and can only rotate, the rotation of the ratchet 43 drives the movable shaft 44 to move forward and backward, and the slider 6 moves forward and backward accordingly, thereby changing the value of the lower lever part a. The value of the lower lever part a changes, thereby changing the ratio of the upper lever part b to the lower lever part a. In this way, the force arm 41 of the adjustment mechanism 4, the support block 42, the ratchet 43, the movable shaft 44 and the slider 6 are coordinated to achieve the change of the output force of the spring assembly 3, which can meet the load changes of different door panels, and has a simple structure and high stability, thereby ensuring the quality of the door panel.

[0033] Furthermore, guide slots 48 are provided on both sides of the lower part of the force arm 41, and directional protrusions 49 are provided on both sides of the slide block 6 to slide in cooperation with the guide slots 48, thereby improving the stability of adjustment and ensuring the adjustment accuracy.

[0034] At the same time, through holes 410 for rotating the ratchet wheel 43 are respectively opened on both sides of the force arm 41, which is convenient for operation and ensures the normal use of the door panel.

[0035] Reference Figures 1 to 5 As shown, the lower end of the lever arm 41 is provided with an angle adjustment wheel 10 for adjusting the swing amplitude, one end of the angle adjustment wheel 10 is positioned and rotatably connected to the lower part of the driving base 1, and the other end of the angle adjustment wheel 10 is threadedly connected to the lever arm 41. With the structure of the angle adjustment wheel 10, the swing amplitude of the adjustment mechanism 4 is effectively adjusted, the lever ratio of the lever arm 41 is further adjusted, and the door panel load is further adjusted to adapt to the use of large-load door panels.

[0036] Reference Figures 1 to 5 As shown, the driving base 1 is provided with a mounting sleeve 7, the mounting sleeve 7 is provided with a buffer cylinder 8 and an adjusting wheel 9 for adjusting the buffer force of the buffer cylinder 8, the buffer cylinder 8 is slidably mounted on the mounting sleeve 7, one end of the mounting sleeve 7 is threadedly connected with the adjusting wheel 9, the adjusting wheel 9 is positioned and connected with the push rod of the buffer cylinder 8, and the connecting rod assembly 2 is folded in the driving base 1 while contacting with the buffer cylinder 8. Under the action of the buffer cylinder 8, the buffer effect is improved, the service life of the door panel is extended, and the quality of the door panel is enhanced.
