[0033] See also Figure 1-Figure 6 , which is a schematic diagram of a height adjustment structure of a drawer hidden rail provided in one embodiment of the utility model, wherein the height adjustment structure of the drawer hidden rail comprises a hidden rail 100 clamped at the bottom of the drawer, and a height adjustment mechanism 200 clamped on the hidden rail 100 and movably connected to the hidden rail 100, wherein:

[0034] In order to realize the height adjustment function of the drawer, a height adjustment mechanism 200 is provided on the hidden rail 100. The hidden rail 100 is clamped at the bottom of the drawer and is movably connected to the drawer. The hidden rail 100 includes a third side rail 130, and a first side rail 110 and a second side rail 120 respectively arranged on both sides of the third side rail 130, and the first side rail 110 and the second side rail 120 are arranged on the same side of the third side rail 130. In order to accommodate the height adjustment mechanism 200, a first clamping groove 111, a second clamping groove 121 and a third clamping groove 131 are respectively arranged on the first side rail 110, the second side rail 120 and the third side rail 130, so as to clamp the height adjustment mechanism 200.

[0035] Furthermore, the first clamping groove 111 and the second clamping groove 121 are respectively inclined at the same angle on the first side rail 110 and the second side rail 120, so that the first clamping groove 111 and the second clamping groove 121 are arranged in parallel, thereby ensuring that the height adjustment mechanism 200 slides smoothly along the first clamping groove 111 and the second clamping groove 121. It is worth noting that the width of the second clamping groove 121 is greater than the width of the first clamping groove 111, and is aligned with the first clamping groove 111 in a direction perpendicular to the second clamping groove 121, and the side of the first clamping groove 111 close to the third side rail 130 overlaps with the side of the second clamping groove 121 close to the third side rail 130, so that the height adjustment mechanism 200 will not tilt during the movement process, thereby ensuring that the drawer can be lifted smoothly.

[0036] Furthermore, a plurality of engaging teeth 122 are evenly arranged at intervals along the inclination direction of the second engaging groove 121 on one side of the second engaging groove 121 away from the third side rail 130, and the engaging teeth 122 are used to be engaged with the height adjustment mechanism 200. When the height adjustment mechanism 200 moves to a suitable height, it only needs to be engaged with the engaging ruler, and the current height is locked, and if the accuracy of height adjustment needs to be improved, the gap between the engaging teeth 122 only needs to be reduced.

[0037] Furthermore, a through slot 123 is provided on the second side rail 120, and the through slot 123 is connected to the second clamping slot 121. When installing the height adjustment mechanism 200, the height adjustment mechanism 200 is passed through the through slot 123 so that one end of the height adjustment mechanism 200 abuts against the first side rail 110, and then moved along the tilt direction of the first clamping slot 111 by a preset distance.

[0038] In addition, a buffer plate 132 extends from the third clamping slot 131 toward the height adjusting mechanism 200, and the downward extending inclination direction of the buffer plate 132 is the same as the inclination angle of the first clamping slot 111 and the second clamping slot 121. When the adjusting mechanism is installed, the top of the adjusting mechanism is overlapped on the buffer plate 132. At the same time, a receiving slot 133 for docking with the second clamping edge 230 is also provided on the side of the third clamping slot 131 close to the second side rail 120, so that when the height adjusting mechanism 200 moves, the receiving slot 133 can effectively avoid the height adjusting mechanism 200, so that it can move normally to adjust the height of the drawer.

[0039] In order to cooperate with the hidden rail 100 to achieve the height adjustment of the drawer, the height adjustment mechanism 200 includes a top height plate 210, a first clamping edge 220 and a second clamping edge 230 respectively arranged on both sides of the top height plate 210, and a height adjustment member 240 is also arranged on the second clamping edge 230. The first clamping edge 220 includes a first connecting portion 221 and a first clamping portion 222 arranged at one end of the first connecting portion 221 away from the top height plate 210, and the first clamping portion 222 is clamped in the first clamping groove 111. The second clamping edge 230 includes a second connecting portion 231 and a second clamping portion 232 arranged at one end of the second connecting portion 231 away from the top height plate 210, and the second clamping portion 232 is attached to the side wall of the second clamping groove 121 close to the third side rail 130. The first connecting portion 221 and the second connecting portion 231 are both stepped, so as to abut against the inner side walls of the first side rail 110 and the second side rail 120 respectively.

[0040] It is worth noting that when the lifting sheet 210 overlaps the buffer sheet 132, the first clamping portion 222 and the second clamping portion 232 are respectively clamped on the first clamping groove 111 and the second clamping groove 121, and because the first connection portion 221 and the second connection portion abut against the inner wall of the first side rail 110 and the second side rail 120, the height adjustment mechanism 200 will not fall off from the hidden rail 100. At the same time, in order to ensure the smoothness of movement, the inclination angles of the first connection portion 221 and the second connection portion 231 are also the same as the inclination angles of the first clamping groove 111 and the second clamping groove 121.

[0041] In addition, in order to facilitate the top plate 210 to cut into the buffer plate 132 better, the side of the top plate 210 close to the buffer plate 132 is beveled so that the top plate 210 and the buffer plate 132 can be overlapped more smoothly.

[0042] In order to achieve the function of adjusting the height of the drawer top, one end of the height adjustment member 240 is connected to the second connecting portion 231 and is arranged in parallel with the second clamping portion 232. At the same time, a height adjustment gap 250 is left between the height adjustment member 240 and the second clamping portion 232, so that the height adjustment member 240 can be moved, thereby pushing the height adjustment mechanism 200. The end of the height adjustment member 240 away from the second connecting portion 231 is provided with a docking port 241 and a toggle portion 242, and the docking port 241 is used to be clamped in the clamping tooth 122 to lock the rising height of the top height plate 210. The toggle portion 242 is processed with a curved edge to facilitate toggle toward the side close to the third rail edge, so that the toggle portion 242 and the clamping tooth 122 are separated, thereby pushing the height adjustment mechanism 200, and achieving the height adjustment function.

[0043] In summary, according to a height adjustment structure of a hidden rail of a drawer provided by the utility model, the first clamping edge and the second clamping edge are clamped on the first side rail and the second side rail respectively, and the top height piece is cut into the third clamping groove at an angle, and the height adjustment piece is pushed along the direction of the second clamping groove so that the top height piece can lift the drawer, thereby realizing the drawer lifting function. Specifically, the hidden rail is clamped at the bottom of the drawer and is movably connected with the drawer, including the third side rail, and the first side rail and the second side rail respectively arranged on both sides of the first side rail. The height adjustment mechanism includes a top height piece, the first clamping edge and the second clamping edge respectively arranged on both sides of the top height piece, and a height adjustment piece is also arranged on the second clamping edge. The first side rail, the second side rail and the third side rail are sequentially provided with a first clamping groove, a second clamping groove and a third clamping groove, the first clamping edge is clamped on the first clamping groove, the second clamping edge and the height adjustment piece are clamped on the second clamping groove, and the top height piece is cut into the third clamping groove at an angle. Since the height adjusting piece and the top height plate are both at the lowest point in the initial state, when the height adjusting piece is pushed along the second clamping groove, the first clamping edge and the second clamping edge move obliquely upward along the inclination direction of the first clamping groove and the second clamping groove respectively, and at the same time, the top height plate also rises along the inclination direction until the drawer is lifted up, thereby reducing the gap between the drawer and the cabinet body, improving the adaptability between the drawer and the cabinet body, and making the overall look more beautiful!
