[0041] Example 1

[0042] like Figure 1-3 As shown, the utility model provides an articulated structure of a grinding and matching machine, which is applied between a slider of the grinding and matching machine and a flap connected to the bottom of the slider, and the flap is connected to the bottom of the slider through the articulated structure, wherein the articulated structure includes: an articulated seat, an articulated block, a rotating shaft and a locking unit.

[0043] The hinge seat is arranged on the bottom side of the slider, a first groove is provided on the outer side surface of the hinge seat, the outer side surface of the hinge seat is a vertical outer side surface, and the inner side surface of the hinge seat is connected to the slider.

[0044] The first end side surface of the hinge block is tightly connected to the outer side surface of the hinge seat, and the first end side surface of the hinge block is provided with a second groove corresponding to the first groove. When the side surface of the hinge block is correspondingly connected to the outer side surface of the hinge seat, the first groove and the second groove are aligned with each other to form a locking groove. The rotating shaft is rotatably penetrated through the second end of the hinge block, and the rotating shaft and the hinge block are rotatably connected through a bearing. Both ends of the rotating shaft extend out of the hinge block and are rotatably connected to the edge of the flap.

[0045] The locking unit is embedded in the locking groove formed by the first groove and the second groove. On the basis that the first end of the hinge block and the hinge seat are fastened through multiple bolts, the locking unit is inserted into the locking groove. The vertical weighing strength of the hinge block and the hinge seat can be further enhanced. After long-term use, a large flipping gap will not be formed between the flap and the slider connected by the hinge structure.

[0046] The overall articulation is achieved by an articulation seat fixed on the slider and an articulation block on the fixed flap. One end of the articulation block is connected to the articulation seat, and the other end is rotatably connected to the flap to achieve articulation. A first groove and a second groove are respectively provided on the vertical side surfaces between the articulation seat and the articulation block. A locking groove is formed by the two grooves. The locking groove is embedded and fastened by a locking unit to enhance the connection stability between the articulation seat and the articulation block. The first groove and the second groove are located on the vertical side surfaces. After the locking unit is inserted, the articulation seat and the articulation block can be prevented from being easily loosened due to the influence of gravity.

[0047] Wherein, the locking unit includes at least one wedge-shaped locking block, and the wedge-shaped locking block is matched and embedded in the locking groove. By setting the locking unit as a wedge-shaped locking block, the wedge-shaped structure can be easily inserted.

[0048] like Figure 4 As shown, in order to eliminate the gap between the slider and the flap, when the flap is located at the bottom of the slider after a long period of action, a gap may appear between them, and a gasket is added to eliminate the gap; specifically, the vertical length of the first groove is greater than the vertical length of the second groove, so that a gap for adjustment is reserved above the first groove, and the gasket is inserted into the bottom of the locking unit in the first groove to lift the hinge block and the flap connected thereto as a whole, thereby eliminating the gap between the flap and the slider. The gasket is not shown in the figure. When the gasket needs to be inserted, the gasket is inserted into the first groove at the bottom of the locking unit.

[0049] The locking unit includes: two wedge-shaped locking blocks and a locking rod. The two wedge-shaped locking blocks are respectively embedded from both ends of the locking groove. The smaller end of the wedge-shaped locking block is inserted into the locking groove toward the inside, and the outline of the larger end of the locking block is larger than the outline of the locking groove.

[0050] The locking rod penetrates and connects the two wedge-shaped locking blocks and tightens the two wedge-shaped locking blocks inwardly, so that the two wedge-shaped locking blocks are prevented from sliding outwards after being inserted.

[0051] Specifically, the inclined surface of the wedge-shaped locking block is perpendicular to the joint surface of the first groove and the second groove. At this time, when the wedge-shaped locking block is locked inward, it can be tightened in the vertical direction, and the hinge seat and the hinge block are contacted and connected in the vertical direction through the side, thereby improving the stability and connection strength in the vertical direction.

[0052] A notch is provided on the edge of the flap corresponding to the second end of the hinge block, and both ends of the rotating shaft in the notch are hinged to the flap. The second end of the hinge block is extended into the notch, and the rotating shaft at the second end of the hinge block is connected to the inner wall of the notch to improve the strength of the connection.

[0053] In this embodiment, two positioning blocks are also included which are sleeved on both ends of the rotating shaft and are used to be fastened to the flap. A positioning groove is provided on the inner side wall of the notch, and a positioning protrusion is provided on the positioning block which is embedded in and matches the positioning groove.

[0054] By matching the protrusion on the positioning block with the positioning groove set in the notch, after the positioning block and the flap are fastened together, the rotating shaft and the flap can be better positioned; and by the positioning blocks sleeved on both ends of the rotating shaft, the positioning block and the flap are fixed, which can make it easier for the rotating shaft to extend into the notch of the flap to achieve a rotational connection.

[0055] Specifically, the length direction of the positioning groove is kept parallel to the axial direction of the rotating shaft, so that the center positioning of the rotating shaft is more accurate, there is no deviation after flipping, and the flipping position is more accurate.

[0056] In this embodiment, a reinforcing seat fixed on the slider is provided on the side of the hinge seat close to the slider, the reinforcing seat is fixed on the inner side of the hinge seat, and the hinge seat is connected and fixed to the bottom edge of the slider side through the reinforcing seat, wherein the reinforcing seat includes two reinforcing ribs arranged vertically to improve the tensile strength in the vertical direction.
