[0017] like Figure 1-Figure 3 As shown, the present embodiment proposes an assembly-free sandwich panel structure, comprising an upper panel 1, a middle panel 2 and a lower panel 3 which are sequentially abutted and distributed from top to bottom, and a connecting component for connecting the upper panel 1, the middle panel 2 and the lower panel 3.

[0018] The upper plate 1 has a plurality of slots a opening downwards, and one lateral end of the upper plate 1 has a slope a inclined downwards, so the structure is regular and beautiful.

[0019] The middle plate 2 has through holes 201 corresponding to the slots a one-to-one.

[0020] The lower plate 3 has a card slot b301 corresponding to the through hole 201 and opening upward, and one lateral end of the lower plate 3 has an inclined surface b inclined upward, and the structure is regular and beautiful.

[0021] The connection assembly includes a latch rod 4 and an expansion hardware 5. The latch rod 4 passes through the through hole 201. The latch rod 4 has a barbed platform a, a rod-piercing portion and a snap-in head connected in sequence. The barbed platform a is snap-fitted in the slot a. The rod-piercing portion passes through the through hole 201. The snap-in head is a spherical structure. The latch rod 4 is plugged into the expansion hardware 5. The expansion hardware 5 has a barbed platform b snap-fitted in the slot b301 and a snap-in space for the snap-in head to snap in. The snap-in space includes a connected guide channel and a spherical space.

[0022] The size of one end of the guide channel connected to the spherical space is smaller than the diameter of the spherical space, and the size of the guide channel gradually increases in the direction away from the spherical space. The embedding head of the latch rod 4 can smoothly pass through the guide channel and be embedded in the inner side of the spherical space. The embedding head is tightened on the end connecting the spherical space and the guide channel, so that the latch rod 4 and the expansion hardware 5 are firmly plugged in and not easy to loosen, and the upper plate 1, the middle plate 2 and the lower plate 3 can also be firmly connected.

[0023] This embodiment is conveniently and efficiently assembled by means of snap-in and plug-in. The latch rod 4 is firmly snap-into the slot a of the upper plate 1 through the barbed platform a, and the expansion hardware 5 is firmly snap-into the inner side of the slot b301 of the lower plate 3 through the barbed platform b, and then the middle plate 2 is placed on the lower plate 3, the through hole 201 is aligned with the slot b301, and then the latch rod 4 is aligned with the through hole 201, and the upper plate 1 is pressed downward, the latch rod 4 passes through the through hole 201, and the snap-in head is snap-into the inner side of the snap-in space of the expansion hardware 5, so that the upper plate 1, the middle plate 2 and the lower plate 3 are firmly connected, and the connection method is simple and easy to operate, reducing the installation steps and the required tools, and reducing the installation difficulty and time cost. This sandwich panel structure can be widely used in various furniture manufacturing fields, such as wardrobes, bookcases, bed frames, etc. Its advantage is that it simplifies the assembly process of furniture and improves production efficiency.

[0024] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
