[0026] It also includes a driving plate 7 disposed in the accommodating chamber 3, and the driving plate 7 is protruded and provided with a plurality of second sliders 71 on its upper and lower end surfaces. Correspondingly, a second slide groove 32 is opened in the accommodating chamber 3, and the second slider 71 extends into the second slide groove 32 to slide, thereby defining a sliding track of the driving plate 7;

[0027] The first adjusting bolt 72 is provided on the driving plate 7, and the first adjusting bolt 72 is connected to the cabinet seat 2. The first adjusting bolt 72 is rotated to push the driving plate 7 to move relative to the cabinet seat 2 along the direction of the second sliding groove 32.

[0028] It also includes a driving inclined rail 73 arranged on the driving plate 7. Correspondingly, a driving inclined groove 62 cooperating therewith is arranged on the sliding plate 6. The driving inclined rail 73 is slidably installed in the driving inclined groove 62. When the driving plate 7 moves, the driving inclined groove 62 and the driving inclined rail 73 are mutually squeezed to push the driving plate 7 to move.

[0029] It also includes a plurality of third slide grooves 63 arranged on the sliding plate 6. Correspondingly, a guide shaft 41 is arranged on the adjusting seat 4 and extends into the third slide groove 63. A second adjusting bolt 65 is also installed on the sliding plate 6 and connected to the adjusting seat 4. The second adjusting bolt 65 is rotated to drive the adjusting seat 4 to move relative to the sliding plate 6 along the direction of the third slide groove 63.

[0030] In one embodiment, the inclination angle between the driving inclined rail 73 and the driving inclined slot 62 and the front end surface 21 of the cabinet base 2 is set to 30° to 60°.

[0031] In one embodiment, the first slide groove 31 and the second slide groove 32 are arranged perpendicular to each other.

[0032] In one embodiment, a retaining groove 22 is provided in the cabinet base 2 , the bolt head of the first adjusting bolt 72 is rotatably retained in the retaining groove 22 , and the stud portion of the first adjusting bolt 72 is threadedly connected to the first adjusting hole 74 on the driving plate 7 .

[0033] In one embodiment, the outer end of the locking slot 22 passes through the front end surface 21 of the cabinet base 2 .

[0034] In one of the embodiments: the sliding plate 6 is also provided with a second adjustment hole 66, and the second adjustment bolt 65 is screwed into the second adjustment hole 66; the adjustment seat 4 is provided with a limit slot 42, and correspondingly, a limit platform 67 is provided on the stud of the second adjustment bolt 65, and the limit platform 67 is rotatably mounted in the limit slot 42.

[0035] In one embodiment, a space-avoiding groove 23 is disposed on the front end surface 21 of the cabinet seat 2 , and the space-avoiding groove 23 is disposed at a position corresponding to the second adjustment hole 66 .

[0036] Working principle: When the user needs to make a left-right fine adjustment, the first adjusting bolt 72 is rotated by a screwdriver, and the first adjusting bolt pushes the driving plate 7 to move relative to the cabinet base 2 along the direction of the second sliding groove 32. At the same time, the driving inclined rail 73 on the driving plate 7 slides in the driving inclined groove 62 on the sliding plate 6, and the sliding plate 6 is pushed to slide left and right through the mutual squeezing of the two, and the adjusting plate is driven to move left and right by the sliding plate, and finally the lateral fine adjustment is achieved.

[0037] It should be noted that the driving inclined rail 73 in this case is completely embedded in the driving inclined groove. Therefore, no matter which direction the driving plate drives the driving inclined rail to move, the driving inclined rail 73 and the driving inclined groove can cooperate to drive the sliding plate to slide left and right, thereby achieving left and right bidirectional adjustment. In addition, due to the large contact area between the driving inclined rail 73 and the driving inclined groove, the pressure can be effectively dispersed, thereby effectively avoiding damage to related components due to deformation during the adjustment process or jamming during the adjustment process.

[0038] When the user needs to fine-tune the front and rear, the user rotates the second adjusting bolt 65 with a screwdriver, and the second adjusting bolt 65 drives the adjusting seat 4 to move relative to the sliding plate 6 along the direction of the third sliding groove 63, thereby finally achieving fine-tune the front and rear.

[0039] Among them, in order to ensure the stability of the movement between the sliding plate and the adjusting plate, the adjusting plate in this case is clamped and installed on the upper and lower end surfaces of the sliding plate, and a number of guide shafts 41 are arranged on the adjusting plate to extend into the third sliding groove 63, providing a basis for the relative displacement between the sliding plate and the adjusting plate, so as to ensure the stable movement of the sliding plate 6.

[0040] To sum up the above, through such principles and action processes, users can easily make fine adjustments left and right and front and back to achieve precise coordination between the door leaf and the cabinet body, so that it can reach the best usage state.

[0041] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the present invention.
