[0045] Embodiment 1:

[0046] As Figures 1 - 3 And in combination with Figure 6As shown in the figure, a corner connection joint for a cabinet in this embodiment is used to connect the first profile 4, the second profile 5, and the third profile 6 that are perpendicular to each other at the corner of the cabinet. The corner connection joint mainly includes: a first joint 1 and a second joint 2. Among them, the first joint 1 is provided with a first abutting portion 101 and a second abutting portion 102. When the first joint 1 is arranged between the first profile 4 and the second profile 5: the first abutting portion 101 abuts against the first profile 4, the second abutting portion 102 abuts against the second profile 5, and the first abutting portion 101 is fixedly connected to the first profile 4 and / or the second abutting portion 102 is fixedly connected to the second profile 5. It should be explained that it is optimal to weld and fix the first joint 1 to both the first profile 4 and the second profile 5. Of course, it is also possible to vertically fix the first profile 4 and the second profile 5 to form a side frame, and then fix the first joint 1 to the first profile 4 or the second profile 5. Among them, the settings of the first abutting portion 101 and the second abutting portion 102 ensure that the first joint 1 abuts tightly against the first profile 4 and the second profile 5 without gaps, ensuring that the first joint 1 will not become loose from the first profile 4 and the second profile 5.

[0047] Specifically, as Figure 3 , Figure 5 and Figure 7 shown, the first joint 1 includes a main body 11 and a contact head 12 extending from the main body 11. The contact head 12 is integrally provided with the main body 11. The side surface of the main body 11 close to the second joint 2 and the side surface of the contact head 12 close to the second joint 2 are both configured as the first abutting portion 101. That is, during use, the side surface of the main body 11 close to the second joint 2 and the side surface of the contact head 12 close to the second joint 2 both abut against the first profile 4, ensuring that the first profile 4 is not easily deformed. The bottom surface of the main body 11 and the bottom surface of the contact head 12 are both configured as the second abutting portion 102. That is, the bottom surface of the main body 11 and the bottom surface of the contact head 12 are on the same horizontal plane. During use, both of their bottom surfaces are in contact with the second profile 5, ensuring no gap between them and ensuring the relative position stability of the first joint 1 with the first profile 4 and the second profile 5. Among them, a convex strip 111 protrudes from the side surface of the main body 11 close to the second joint 2, and the convex strip 111 forms a limit for the second profile 5.

[0048] The second joint 2 is separately arranged from the first joint 1. A third abutting portion 21 is provided on the second joint 2. When the second joint 2 is fixedly connected to the third profile 6, the third abutting portion 21 abuts against the third profile 6 to ensure no gap between the second joint 2 and the third profile 6. Specifically, the bottom surface and at least one side surface of the second joint 2 are configured as the third abutting portion 21, that is, at least two surfaces of the third profile 6 abut against the second joint 2. A clamping groove 22 is provided at the top of the second joint 2, and a clamping block 23 is provided at the bottom. When the third profile 6 is fixedly connected to the second joint 2, the third profile 6 is clamped with both the clamping groove 22 and the clamping block 23 to ensure the position of the second joint 2 on the third profile 6 is determined and reliable. During actual use, when connecting the first profile 4, the second profile 5, and the third profile 6 through the corner connection joint of this embodiment: the first joint 1 can be first fixedly welded to the first profile 4 and / or the second profile 5, and the second joint 2 can be fixedly welded to the third profile 6; then the first joint 1 and the second joint 2 are fixedly connected, ensuring simple assembly and eliminating the need to sequentially fix the first profile 4, the second profile 5, and the third profile 6 to the corner connection joint in sequence.

[0049] As a preferred solution, the first joint 1 and the second joint 2 in this embodiment are fixedly connected by a connecting bolt 3. Specifically: a through hole 110 is provided on the first joint 1, and a threaded hole 20 corresponding to the through hole 110 is provided on the second joint 2. The connecting bolt 3 passes through the through hole 110 and is threadedly connected in the threaded hole 20, detachably fixing the first joint 1 and the second joint 2 and ensuring simple disassembly and assembly.

[0050] As an alternative solution, the first joint 1 and the second joint 2 can also be fixedly connected by riveting (not shown in the figure).

[0051] During actual use, the corner connection joint of this embodiment includes a first joint 1 and a second joint 2 that are separately arranged. During actual assembly, the first joint 1 can be first fixed to the first profile 4 and the second profile 5, and the second joint 2 can be fixed to the third profile 6, and then the first joint 1 and the second joint 2 are fixedly connected to achieve the vertical fixed connection of the first profile 4, the second profile 5, and the third profile 6, eliminating the need to sequentially connect the three profiles to the corner connection joint and facilitating customer assembly. Moreover, when the corner connection joint fixedly connects the three profiles, the first abutting portion 101 and the second abutting portion 102 respectively abut against the first profile 4 and the second profile 5, and the third abutting portion 21 abuts against the third profile 6, ensuring no gap is formed between the corner connection joint and the three profiles, thereby ensuring the stability of the connection.

[0052] Embodiment 2:

[0053] As Figures 7 - 9As shown in the figure, the corner connection joint for a cabinet in this embodiment is another implementation form of the corner connection joint. The main difference between the corner connection joint in this embodiment and the corner connection joint in the first embodiment lies in the slight difference in the structure of the second joint 2.

[0054] Specifically, the first joint 1 of the corner connection joint in this embodiment is the same as the first joint in the corner connection joint of the first embodiment. In this embodiment, two clamping blocks 23 are provided at the bottom of the second joint 2, and the card slot at the top of the second joint 2 is cancelled. The structure of the second joint 3 can be designed according to the specific cross-sectional shape of the third profile 6. When the second joint 2 is fixedly connected to the third profile 6, the two clamping blocks 23 on the second joint 2 are clamped with the third profile 6, and the second abutting portion 101 on the second joint 2 abuts against the third profile.

[0055] The usage method of the corner connection joint in this embodiment is the same as that in the first embodiment, and will not be elaborated here.

[0056] Embodiment Three:

[0057] As Figures 4 - 6 shown, taking the application scenario of the corner connection joint in the first embodiment as an example, a connection assembly in this embodiment mainly includes:

[0058] The first profile 4, the second profile 5, the third profile 6, and the corner connection joint in the first embodiment. Among them, the first joint 1 is arranged between the first profile 4 and the second profile 5 and is fixedly connected to the first profile 4 and / or the second profile 5; the second joint 2 is fixedly connected to the third profile 6; the first joint 1 is fixedly connected to the second joint 2; the first profile 4, the second profile 5, and the third profile 6 are perpendicular to each other.

[0059] In the actual assembly process, first weld and fix the first joint 1 between the first profile 4 and the second profile 5, that is, the first joint 1, the first profile 4, and the second profile 5 are fixed. At this time, the first abutting portion 101 of the first joint 1 abuts against the first profile 4, and the second abutting portion 102 abuts against the second profile 5. And, the second joint 2 is welded and fixed on the third profile 6. At this time, the third abutting portion 21 on the second joint 2 abuts against the third profile 6. Then, pass the connecting bolt 3 through the through hole 110 on the first joint 1 and thread it into the threaded hole 20 on the second joint 2 to realize the fixed connection between the first joint 1 and the second joint 2, and further fix and connect the first profile 4, the second profile 5, and the third profile 6 with the corner connection joint.
