The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] See also Figure 1-Figure 4 , which is a schematic diagram of a drawer hidden rail with a height adjustment structure provided in one embodiment of the utility model, the drawer hidden rail with a height adjustment structure comprises a hidden rail 100 clamped at the bottom of the drawer, and a height adjustment structure 200 clamped in the height adjustment groove 110 and rotatably connected to the hidden rail 100, wherein:

[0031] In order to adjust the height of the drawer by using the height adjustment structure 200, a height adjustment slot 110 is provided on the hidden rail 100. The height adjustment slot 110 includes a first notch 120 and a second notch 130 respectively provided on both sides of the hidden rail 100. The height adjustment structure 200 is clamped in the first notch 120 and the second notch 130 to achieve the effect of lifting the drawer. In order to lock the drawer after lifting it to a certain height, a second toothed portion 121 used in conjunction with the height adjustment structure 200 is provided on the inner periphery of the first notch 120, so that the height adjustment structure 200 can be locked after rotating to a certain angle, and the drawer can be used at a certain height.

[0032] Furthermore, limit members 140 are symmetrically provided on both sides of the second groove 130 on the inner wall of the hidden rail 100 to clamp the height adjustment structure 200 to prevent it from cyclically rotating in the height adjustment groove 110, thereby limiting the rotation angle range of the height adjustment structure 200 and also limiting the adjustable height range of the drawer.

[0033] In order to realize the height-adjustable function of the drawer, the height-adjusting structure 200 includes a clamping assembly 210 for rotationally connecting with the hidden rail 100, a height-adjusting member 220 disposed in the height-adjusting slot 110, and a handle assembly 230 disposed on one side of the clamping assembly 210. The handle assembly 230 is rotated to drive the height-adjusting member 220 through the clamping assembly 210 to lift the drawer disposed on the hidden rail 100, and the clamping assembly 210 is clamped on the hidden rail 100 to adjust the lifting height of the height-adjusting member 220.

[0034] In order to facilitate the rotation of the height adjustment member 220 on the hidden rail 100, the clamping assembly 210 includes a first clamping member 211 and a second clamping member 213 respectively disposed in the first notch 120 and in the second notch 130. The height adjustment member 220 is disposed between the first clamping member 211 and the second clamping member 213, and rotates coaxially with the first clamping member 211 and the second clamping member 213. When the first clamping member 211 and the second clamping member 213 drive the height adjustment member 220 to rotate to a suitable angle in the height adjustment slot 110, so that the drawer reaches a suitable height for use, in order to lock the current angle, a first toothed portion 212 is disposed on the outer periphery of the first clamping member 211, and the first toothed portion 212 disposed on the outer periphery of the first clamping member 211 and the second toothed portion 121 disposed on the inner periphery of the first notch 120 are engaged and connected, thereby locking the height adjustment member 220, and thereby locking the height of the drawer.

[0035] Furthermore, the height adjusting member 220 is provided with a first limit opening 221 and a second limit opening 222 at one end close to the second clamping member 213, and the first limit opening 221 and the second limit opening 222 are used to limit the rotation angle of the height adjusting member 220. Since the limit members 140 are symmetrically arranged on both sides of the second notch 130, when the height adjusting member 220 rotates clockwise or counterclockwise to a certain angle, the first limit opening 221 and the second limit opening 222 can be clamped on the corresponding limit members 140 to prevent the height adjusting member 220 from cyclically rotating on the hidden rail 100. At the same time, the angle between the first limit opening 221 and the second limit opening 222 provided on one side of the height adjusting member 220 also limits the rotation range of the height adjusting member 220, thereby limiting the height adjustment range of the drawer. Due to wear and tear between the drawer and the cabinet after long-term use, a gap appears, resulting in the incompatibility between the two. Rotate the height-adjusting member 220 to raise the drawer, thereby reducing the gap between the drawer and the cabinet, improving the fit between the drawer and the cabinet, and making the overall look more beautiful!

[0036] It is worth mentioning that in order to reduce the wear between the height adjusting member 220 and the bottom of the drawer during the lifting process, the contact surface between the height adjusting member 220 and the drawer adopts an arc slope. Therefore, during the adjustment process, the arc slope can slow down the degree of wear, making the height adjustment smoother and avoiding cliff-like height adjustment.

[0037] To drive the rotation of the height adjustment member 220, the handle assembly 230 includes a first handle member 231 connected to the second engaging member 213, and a second handle member 232 vertically disposed on the end face of the first handle member 231 away from the second engaging member 213. The diameter of the first handle member 231 is greater than the area of the second notch 130 for clamping the height adjustment member 220 in the height adjustment groove 110 to prevent the height adjustment member 220 from falling off and affecting the use. The second handle member 232 is used for manual rotation to drive the rotation of the height adjustment member 220, and it is convenient to use by applying force with fingers. It should be emphasized that a number of anti-slip bumps 233 are evenly arranged on the upper and lower end faces of the second handle member 232 to increase the friction force and facilitate the application of force to the second handle member 232.

[0038] In summary, according to a drawer hidden rail with a height adjustment structure provided by the present invention, by using a clamping assembly to be clamped in the height adjustment groove on the hidden rail, and then rotating the handle assembly, the height adjustment member can jack up the drawer to reach a preset pulling height, thereby ensuring the normal use of the drawer. Specifically, the drawer hidden rail with a height adjustment structure includes a hidden rail clamped to the bottom of the drawer, and a height adjustment structure clamped in the height adjustment groove and rotatably connected to the hidden rail. The hidden rail is provided with a height adjustment groove, and the height adjustment structure includes a clamping assembly for rotatably connecting to the hidden rail, a height adjustment member disposed in the height adjustment groove, and a handle assembly disposed on one side of the clamping assembly. Rotating the handle assembly drives the height adjustment member through the clamping assembly to jack up the drawer disposed on the hidden rail, and the clamping assembly is clamped to the hidden rail to adjust the jacking height of the height adjustment member.
