[0033] In addition to having multiple groups of drawers for storing items, the multifunctional storage cabinet of the present invention also has a first expansion storage mechanism provided on the outer side of the bottom drawer 2. By flipping the front flap panel 5 downward, the first expansion storage mechanism is opened, so that multiple storage boxes 6 on the inner side of the front flap panel 5 are exposed, so that items can be stored in the corresponding storage boxes 6, thereby increasing the storage space.

[0034] In this embodiment, the push-pull bracket 3 is made of high-quality solid aluminum plate, which is more solid and durable than ordinary wood board plastic; the drawer is installed on the cabinet body 1 through a slide rail, wherein the drawer is made of high-quality alloy steel and is integrally formed through a bending process; the slide rail is a silent fully stretchable steel slide rail, which has the advantages of strong bearing capacity and smooth sliding; the front flap door panel 5 is made of stainless steel, and the inner pad adopts an aluminum honeycomb structure, which can be made sturdy and durable; the storage box 6 is a built-in storage box, which is made of ABS plastic or bamboo material, is light and durable, and easy to clean.

[0035] See also Figure 1-Figure 3 A G-shaped handle 7 is arranged above the push-pull bracket 3. The G-shaped handle 7 is made of aluminum. By pulling the G-shaped handle 7, the bottom drawer 2 of the bottom layer can be dragged out, and the user can open the drawer above it.

[0036] See also Figure 1-Figure 3 A G-shaped handle is also provided above the front flap door panel 5. By pulling the G-shaped handle downward, the front flap door panel 5 can be driven to rotate downward, so that multiple storage boxes 6 on the inner side of the front flap door panel 5 are exposed, so that items can be placed in the storage boxes 6 or items in the storage boxes 6 can be taken out.

[0037] See also Figure 1-Figure 3 A connecting hinge 4 is arranged between the push-pull bracket 3 and the front flap door panel 5. The connecting hinge 4 is divided into two groups. The two groups of connecting rods are arranged on both sides of the front flap door panel 5. Each group of connecting rods includes a first connecting rod and a second connecting rod, wherein one end of the first connecting rod is hinged on the push-pull bracket 3, and the other end is hinged to one end of the second connecting rod; the other end of the second connecting rod is hinged to the front flap door panel 5. By setting the connecting hinge 4, it can be used to limit the maximum angle of the front flap door panel 5 to flip downward.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that:

[0040] See also Figure 4-Figure 11 The bottom of the push-pull bracket 3 is provided with a second expansion storage mechanism, and the second expansion storage mechanism includes an expansion drawer 8 and an opening drive mechanism for driving the expansion drawer 8 to pop out, wherein,

[0041] The bottom of the push-pull bracket 3 and the bottom drawer 2 are both provided with avoidance grooves for avoiding the expansion drawer 8, and the expansion drawer 8 can be stored in the avoidance grooves. The two expansion drawers 8 are provided with sliding parts 801, and the bottom of the cabinet 1 is provided with a sliding seat 11 that cooperates with the sliding part 801. The sliding seat 11 is provided with a sliding groove, and the sliding part 801 is installed in the sliding groove. When the G-shaped handle 7 on the push-pull bracket 3 is pulled outward, the bottom drawer 2, the first expansion storage mechanism and the second expansion storage mechanism can move outward synchronously;

[0042] The opening drive mechanism is composed of multiple groups, and each group of opening drive mechanism includes a fixed seat arranged at the bottom of the bottom drawer 2 and a driving rod 9 arranged on the fixed seat, wherein a guide hole is arranged on the fixed seat; one end of the driving rod 9 passes through the guide hole and is connected to the expansion drawer 8, and the other end is connected to a limit block 12, and the outer diameter of the limit block 12 is larger than the inner diameter of the guide hole, which is used to prevent the driving rod 9 from escaping from the guide hole; a compression spring 10 is arranged between the fixed seat and the expansion drawer 8, and the compression spring 10 is sleeved on the driving rod 9, and the elastic force of the compression spring 10 causes the expansion drawer 8 to pop out.

[0043] In addition, when the expansion drawer 8 is not needed, in order to prevent the expansion drawer 8 from popping out when the front flap panel 5 is rotated downward, the expansion drawer 8 needs to be locked. Therefore, a mounting seat is provided on one side of the bottom of the bottom drawer 2, and a locking block 13 is provided on the mounting seat. One end of the locking block 13 is rotatably connected to the mounting seat, and the other end is provided with a locking groove 133; a locking rod 802 is provided on the side of the expansion drawer 8; when the expansion drawer 8 is in a closed state, the locking rod 802 is located in the locking groove 133 of the locking block 13; through the above arrangement, the expansion drawer 8 can be locked.

[0044] See also Figure 4-Figure 11 A guide portion 131 extending obliquely downward is provided at the end of the locking block 13 away from the mounting seat, and a torsion spring is provided at the connection between the locking block 13 and the mounting seat, and the elastic force of the torsion spring prompts the locking block 13 to flip downward; when the expansion drawer 8 needs to be closed, the locking rod 802 on the expansion drawer 8 contacts the guide portion 131 to prompt the locking block 13 to overcome the elastic force of the torsion spring and flip upward, and when the locking rod 802 enters the notch of the locking groove 133, the elastic force of the torsion spring prompts the locking block 13 to flip downward, so that the locking rod 802 cooperates with the locking groove 133.

[0045] See also Figure 4-Figure 11The multifunctional locker also includes a trigger mechanism for driving the locking block 13 to rotate so as to cause the locking groove 133 of the locking block 13 to separate from the locking rod 802, wherein the trigger mechanism includes a first driving block 15 arranged on the front flap panel 5 and a second driving block 14 arranged on the first driving block 15; wherein one end of the second driving block 14 is hinged on the first driving block 15, and the other end extends horizontally toward the direction of the locking block 13; the first driving block 15 is provided with a receiving groove at a position corresponding to the second driving block 14, and the bottom of the receiving groove constitutes a driving part 151 for driving the second driving block 14 to swing upward; a connecting rod 132 is provided in the locking block 13, and the connecting rod 132 is pressed against the second driving block 14 under the elastic force of the torsion spring.

[0046] With the above arrangement, when it is necessary to open the expansion drawer 8, it is only necessary to cause the front flap panel 5 to rotate downward, and the first driving block 15 moves outward while rotating clockwise. During this process, the driving portion 151 on the first driving block 15 gradually rotates from an inclined state to a horizontal state, and the first driving block 15 will also pull the second driving block 14 to move outward. Since the driving portion 151 on the first driving block 15 gradually moves from an inclined state to a horizontal state, the driving portion 151 on the first driving block 15 will generate an upward force on the second driving block 14 to cause the second driving block 14 to rise as a whole, so that the second driving block 14 moves upward as a whole while moving outward; as the second driving block 14 rises as a whole, the second driving block 14 drives the lock block 13 through the connecting rod 132 on the locking block 13. The locking block 13 overcomes the elastic force of the torsion spring and rotates counterclockwise; when the driving part 151 in the first driving block 15 rotates to a horizontal state, the driving part 151 is completely fitted with the bottom of the second driving block 14, and the locking groove 133 in the locking block 13 is not completely separated from the locking rod 802 in the expansion drawer 8; as the front flap 5 continues to rotate downward, the driving part 151 on the first driving block 15 will cause the second driving block 14 to rotate clockwise, so that the height of the end of the second driving block 14 in contact with the connecting rod 132 increases instantly, thereby driving the connecting rod 132 in the locking block 13 to move upward, causing the locking block 13 to overcome the elastic force of the torsion spring and rotate counterclockwise, so that the locking groove 133 in the locking block 13 is separated from the locking rod 802. Under the elastic force of the compression spring 10, the driving rod 9 extends outward and drives the expansion drawer 8 to move outward, thereby opening the expansion drawer 8.

[0047] In the above process, since a return spring 16 is provided between the side of the expansion drawer 8 and the second drive block 14, the upper end of the return spring 16 acts on the expansion drawer 8, and the lower end acts on the second drive block 14; under the action of the return spring 16, the second drive block 14 will rotate downward, thereby driving the first drive block 15 to move inward while also rotating counterclockwise; when the driving portion 151 in the first drive block 15 rotates to a horizontal state, the force acting on the second drive block 14 is in a balanced state, which is equivalent to saying that the return spring 16 plays a damping role, and when the front flap door panel 5 is opened, the front flap door panel When the driving portion 151 in the first driving block 15 is rotated downward until it is in a horizontal state, the front flap panel 5 stops rotating, at which time the trigger mechanism is not triggered, and the expansion drawer 8 does not pop out. In order to trigger the expansion drawer 8 to pop out, it is necessary to continue to apply a downward force to the front flap panel 5 to break this balanced state. As the front flap panel 5 continues to rotate downward, the driving portion 151 in the first driving block 15 drives the second driving portion 151 to rotate clockwise, thereby driving the locking block 13 to rotate counterclockwise, so that the locking groove 133 will be separated from the locking rod 802, and the expansion drawer 8 will pop out. When the expansion drawer 8 pops out, in order to restore this balanced state, the return spring 16 will prompt the second drive block 14 to rotate downward, thereby driving the first drive block 15 to move inward while also rotating counterclockwise until the drive portion 151 in the first drive block 15 is in a horizontal state, at which time it is restored to a force balanced state again. During this process, the front flap door panel 5 will rotate upward by a certain angle, but the front flap door panel 5 is not completely closed, that is, the front flap door panel 5 will be in a critical position when rotating, and in this position, the drive portion 151 in the first drive block 15 is in a horizontal state; continuing to apply a downward force to the front flap door panel 5 will prompt the trigger mechanism to be triggered, and after triggering, stop applying the downward force to the front flap door panel 5, and the front flap door panel 5 will return to the critical position; if an upward force is applied to the front flap door panel 5 at this time, the front flap door panel 5 can also be rotated upward and closed.

[0048] When the expansion drawer 8 needs to be closed, it is only necessary to push the expansion drawer 8 inward so that the locking rod 802 on the expansion drawer 8 contacts the guide portion 131 in the locking block 13, so as to cause the locking block 13 to flip upward against the elastic force of the torsion spring; when the locking rod 802 enters the notch of the locking groove 133, the elastic force of the torsion spring causes the locking block 13 to flip downward, so that the locking rod 802 cooperates with the locking groove 133, thereby locking the expansion drawer 8.

[0049] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
