The axial hole Y2 at one end of the side panel interlocking hinge fastening blade 9b is hinged to the axial hole Q of the side panel interlocking hinge fastening base 7 via an axis. The tension adjustment hole Z2 at the other end is hinged to the tension adjustment section 34a of the side panel interlocking hinge fastening blade adjustment screw 11a, which passes through the front-rear sliding hole X1 of the side panel interlocking hinge spring base 8 and the limiting hole T of the side panel interlocking hinge fastening base 7. The door panel interlocking hinge fastening blades 21a and 21b are connected in the same manner.

[0102] refer to Figure 13 、 5 , 8, 10, 34, rotate the side panel interlocking hinge fastening knife adjusting screw 11a, its limiting section 32a rotates in the limiting hole U of the side panel interlocking hinge fastening seat 7 and the front and rear sliding holes X2 of the side panel interlocking hinge spring seat 8, and its tension adjustment section 34a acts on the tension adjustment hole Z1 of the side panel interlocking hinge fastening knife 9a, and the side panel interlocking hinge fastening knife 9a expands toward the outer circle of the side panel interlocking hinge fastening seat 7 with the shaft hole Y1 as the center of the circle according to the designed curve rule to achieve the tightening effect; rotate the side panel interlocking hinge fastening knife adjusting screw 11a in the opposite direction, and the side panel interlocking hinge fastening knife 9a will take Y1 as the center of the circle, and as the tension adjustment section 34a of the side panel interlocking hinge fastening knife adjusting screw 11a interacts with the tension adjustment hole Z1 of the side panel interlocking hinge fastening knife 9a, it returns to its original position according to the curve rule to complete the loosening action. Here we only explain the action stroke and principle of the side panel interlocking hinge fastening knife 9a (there are two fastening knives in the side panel: 9a, 9b). The door panel interlocking hinge also has two fastening knives, and their action stroke and principle are the same, so they will not be repeated.

[0103] refer to Figure 20 、 9, 8, 21, 5, the interlocking hinge spring slider 13a is built into the middle of the locking piece 55a of the side panel interlocking hinge spring seat 8 and the bottom support 25a of the side panel interlocking hinge fastening seat 7; the interlocking hinge spring slider 13b is built into the middle of the locking piece 55b of the side panel interlocking hinge spring seat 8 and the bottom support 25b of the side panel interlocking hinge fastening seat 7. Among them, the upper inclined surface 56a of the interlocking hinge spring slider 13a is placed under the bottom surface of the locking piece 55a of the side panel interlocking hinge spring seat 8, and the lower inclined surface 56b of the interlocking hinge spring slider 13a is placed on the bottom support 25a of the side panel interlocking hinge fastening seat 7; the upper inclined surface 80a of the interlocking hinge spring slider 13b is placed under the bottom surface of the locking piece 55b of the side panel interlocking hinge spring seat 8, and the lower inclined surface 80b of the interlocking hinge spring slider 13b is placed on the bottom support 25b of the side panel interlocking hinge fastening seat 7.

[0104] refer to Figure 22 、 5 , 9, the interlocking hinge spring 38 passes through the axis hole j and is hinged to the spring axis hole i of the side panel interlocking hinge spring seat 8 via the axis. The spring arms 51a, 51b act on the spring arm sliding grooves 22a, 22b of the spring seat sliders 13a, 13b sliding on both sides of the side panel interlocking hinge spring seat 8 and the bottom supports 25a, 25b of the side panel interlocking hinge fastening seat 7 respectively, and the spring support 52 presses on the bottom support 30 of the side panel interlocking hinge spring seat 8.

[0105] refer to Figure 18 、 12 , 16, 20, 21, the interlocking hinge common main connecting rod side plate sliding shaft 47 passes through the two side sliding grooves 49 of the side plate interlocking hinge mounting seat 10 and the two side common main connecting rod axis hole I of one end of the interlocking hinge common main connecting rod 3, and the extended two ends respectively act on the first section sliding groove 36a, the second section sliding groove 37a of the spring slider 13a on both sides and the first section sliding groove 36b, the second section sliding groove 37b of the spring slider 13b.

[0106] refer to Figure 1 、 2 , 20, 21, 9, 8, 38, 39, 40. When the door panel is opened, the interlocking hinge common main connecting rod side panel sliding shaft 47 slides simultaneously in the sliding groove 49 of the side panel interlocking hinge mounting seat 10, the first and second sliding grooves 36a and 37a of the interlocking hinge spring slider 13a, and the first and second sliding grooves 36b and 37b of the interlocking hinge spring slider 13b. Because the curves of the first and second sliding grooves of the spring slider are designed differently from the curves of the sliding grooves of the side panel interlocking hinge mounting seat, when the interlocking hinge common main connecting rod side panel sliding shaft 47 slides, the dynamic curves of the first and second sliding grooves of the spring slider follow the interlocking hinge common main connecting rod side panel sliding shaft 47 to keep consistent with the curve of the sliding groove of the static mounting seat 10, prompting the interlocking hinge spring sliders 13a and 13b to move back and forth. The same is true when the door panel is closed.

[0107] refer to Figure 18 、 1 , 2, 20, 21, 22, 6, 38, 39, 40, when the door panel is opened, the two ends of the interlocking hinge common main connecting rod side plate sliding shaft 47 slide in the second section sliding groove 37a of the interlocking hinge spring slider 13a and the second section sliding groove 37b of the interlocking hinge spring slider 13b, so that the interlocking hinge spring slider 13a and the interlocking hinge spring slider 13b move in the opposite direction of the door panel opening. Since the spring arms 51a and 51b on both sides of the interlocking hinge spring 38 act on the spring arm sliding groove 22a of the interlocking hinge spring slider 13a and the spring arm sliding groove 22b of the interlocking hinge spring slider 13b respectively, at this time, the spring force is opposite to the force in the opening direction of the door panel, prompting the door panel to generate a force in the closing direction; when the door panel is opened to a certain angle, that is, the interlocking hinge common main connecting rod side plate sliding shaft 47 is connected. When both ends of the panel-side sliding shaft 47 slide to the end point of the second-stage sliding groove 37a of the interlocking hinge spring slider 13a and the starting point of the first-stage sliding groove 36a, and the end point of the second-stage sliding groove 37b of the interlocking hinge spring slider 13b and the starting point of the first-stage sliding groove 36b, the interlocking hinge spring sliders 13a and 13b will move in the same direction as the door panel opening under the action of the interlocking hinge common main connecting rod side panel sliding shaft 47. Due to the elastic force of the spring arms 51a and 51b on both sides of the interlocking hinge spring 38, the force is the same as the force in the door panel opening direction, causing the interlocking hinge spring sliders 13a and 13b to push the interlocking hinge common main connecting rod side panel sliding shaft 47, driving the interlocking hinge common main connecting rod 3 to rotate until the door panel is fully opened. And vice versa.

[0108] refer to Figure 27 、 24 , 37, 35, the bottom surface of the door panel interlocking hinge moving seat 15 is placed on the upper plane of the door panel interlocking hinge fastening seat 14.
