[0033] Adjusting part includes horizontal support plate 4, and the bottom of horizontal support plate 4 is provided with first guide support part 8;The first guide support part 8 is obliquely arranged;In this embodiment, the first guide support part 8 is three groups, and three groups of first guide support part 8 are arranged side by side;The surface of movable rail 5 is provided with avoiding groove 502 for avoiding horizontal support plate 4 and adjusting mechanism, and the first guide support plate 501 extending downwardly in the direction of avoiding groove 502 is arranged on the movable rail 5, and the inclination angle of first guide support plate 501 is same with the inclination angle of first guide support part 8;

[0034] Adjusting mechanism includes second guide support plate 3 arranged on one side of horizontal support plate 4 and push plate 2 for driving second guide support plate 3 to move, wherein, the second guide support plate 3 is connected with the side surface of movable rail 5 through sliding guide mechanism;Sliding guide mechanism is used to promote horizontal support plate 4 to move reversely on first guide support plate 501 along the extension direction of first guide support plate 501, so as to promote horizontal support plate 4 to tilt and lift in horizontal state;Push plate 2 is installed on second guide support plate 3.

[0035] Referring to Figures 3-14The sliding guide mechanism comprises a guide shaft arranged on the side of the movable rail 5 and a guide groove 301 arranged on the second guide support plate 3, wherein the guide groove 301 extends upwardly in an inclined manner and the extension angle of the guide groove 301 is the same as the inclined angle of the second guide support plate 3; one end of the guide shaft is mounted on the side of the movable rail 5 and the other end is connected with a limiting block 6 after passing through the guide groove 301; the outer diameter of the limiting block 6 is larger than the width of the guide groove 301, so as to avoid the guide shaft from being pulled out of the guide groove 301.

[0036] Referring to Figures 3-14 The locking mechanism comprises a locking groove 503 arranged on the movable rail 5 and a locking block 9 arranged on the push plate 2 and matched with the locking groove 503, wherein the locking groove 503 is in multiple groups, the multiple groups of locking grooves 503 are arranged on the side of the movable rail 5 and arranged in sequence along the extension direction of the guide groove 301; the locking block 9 is matched with one group of locking grooves 503; in this embodiment, along the arrangement direction of the locking grooves 503, the inclined angle of the front side surface 5031 of the locking groove 503 is smaller than the inclined angle of the rear side surface 5032 of the locking groove 503, so that when the push plate 2 drives the second guide support plate 3 to move upwardly in an inclined manner, the locking block 9 on the push plate 2 is in contact with the front side surface of the locking groove 503, so that the locking block 9 can climb along the front side surface of the locking groove 503 and enter into the corresponding locking groove 503 (i.e. the locking groove 503 in front), and the locking block 9 cannot enter into the locking groove 503 in the rear direction, so that the locking block can be limited in the corresponding locking groove 503; the push plate 2 and the second guide support plate 3 are connected in a flexible manner; when it is needed to adjust the height of the drawer downwardly, the installer pushes the push plate 2 upwardly, so that the locking block 9 on the push plate 2 is separated from the locking groove 503 on the movable rail 5, then the installer pushes the push plate 2 in a reverse direction, so as to drive the second guide support plate 3 to move downwardly in an inclined manner, thereby driving the horizontal support plate 4 to move downwardly in an inclined manner in a horizontal state; when the horizontal support plate 4 falls to a proper height, the push plate 2 is released, the locking block 9 in the push plate 2 is clamped in the corresponding locking groove 503 again, so that the horizontal support plate 4 is stabilized at the fixed height again.

[0037] Referring to Figures 3-14The inner side of the movable rail 5 is provided with a first limiting block 7, which is installed on the push plate 2, and the gap between the first limiting block 7 and the push plate 2 constitutes a limiting groove; the side wall of the movable rail 5 is located in the limiting groove; and the width of the limiting groove is greater than or equal to the wall thickness of the side wall of the movable rail 5. Since the push plate 2 and the second guide support plate 3 are connected by flexibility, when the installer pushes the push plate 2 to drive the second guide support plate 3 to tilt, the push plate 2 is prone to horizontal torsion. Therefore, by arranging the first limiting block 7, the limiting groove formed between the first limiting block 7 and the push plate 2 can clamp the side wall of the movable rail 5, so as to limit the horizontal torsion of the push plate 2. In this way, the force applied by the installer to the push plate 2 can only drive the push plate 2 to tilt, so as to better drive the second guide support plate 3 to move, thereby adjusting the height of the horizontal support plate 4, and the use is better.

[0038] Referring to Figures 3-14 The horizontal support plate 4 is provided with a second limiting block 10 at the end away from the first guide support plate 501, the second limiting block 10 comprises a first limiting part 1001 and a second limiting part 1002 arranged at the bottom of the first limiting part 1001, wherein the first limiting part 1001 is vertically arranged, and the second limiting part 1002 is obliquely arranged, and the oblique angle is the same as the oblique angle of the first guide support plate 501; the upper and lower sides of the first guide support plate 501 are located between the first guide support part 8 and the second limiting part 1002. By arranging the second limiting block 10, the horizontal support plate 4 can be limited to move only along the inclined direction of the first guide support plate 501. In other words, the first guide support part 8 of the horizontal support plate 4 and the first limiting part 1001 and the second limiting part 1002 in the second limiting block 10 jointly constitute a guide groove; and the first guide support plate 501 constitutes a guide part matched with the guide groove, so as to facilitate the relative sliding of the two. During the sliding process, the horizontal support plate 4 always moves along the inclined direction of the first guide support plate 501, and the surface of the horizontal support plate 4 always maintains a horizontal posture during the tilting movement of the horizontal support plate 4.

[0039] Referring to Figures 3-14A damping buffer 1 is provided between the movable rail 5 and the fixed rail; the housing of the damping buffer 1 is provided with a second guide support part 101 at a position corresponding to the second guide support plate 3, and the inclination angle of the second guide support part 101 is the same as the inclination angle of the guide groove 301; by providing the second guide support part 101, the movement of the second guide support plate 3 can be guided and supported, thereby ensuring the adjustment accuracy of the adjustment mechanism for the height adjustment of the horizontal support plate 4.

[0040] See Figures 3-14 The working principle of the height adjustment device of this utility model for adjusting the height difference of drawers is as follows:

[0041] When the height of the drawer needs to be adjusted upwards, the installer can push the push plate 2, which will cause the second guide support plate 3 to tilt upwards, and then cause the horizontal support plate 4 to tilt upwards in a horizontal state. After adjusting to a suitable height, the push plate 2 is released, and the locking block 9 in the push plate 2 is locked in the corresponding locking groove 503, thereby locking the second guide support plate 3 and stabilizing the horizontal support plate 4 at a fixed height.

[0042] When the drawer height needs to be adjusted downwards, the installer pushes the push plate 2 upwards, causing the locking block 9 on the push plate 2 to separate from the locking groove 503 on the movable rail 5. Then, the installer pushes the push plate 2 in the opposite direction, thereby causing the second guide support plate 3 to tilt downwards, which in turn causes the horizontal support plate 4 to tilt downwards in a horizontal posture. When the horizontal support plate 4 falls to the appropriate height, the push plate 2 is released, and the locking block 9 in the push plate 2 is once again locked in the corresponding locking groove 503, so that the horizontal support plate 4 is stabilized at a fixed height again.

[0043] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
