[0043] A diagonal brace hollow structure 45 is formed between the front diagonal brace rod 41, the right diagonal brace connector 43, the rear diagonal brace rod 42 and the cabinet connecting plate 44. The shape of the diagonal brace hollow structure 45 is approximately a trapezoidal structure. The length extension direction of the cabinet connecting plate 44 is greater than the length extension direction of the right diagonal brace connector 43, thereby increasing the contact area with the cabinet, thereby ensuring that the opposite sides of the cabinet (such as the left and right sides) are respectively fixedly connected to the cabinet connecting plate 44 in the left diagonal brace member 4 and the cabinet connecting plate 44 in the right diagonal brace member 5.

[0044] The front diagonal brace rod 41 and the rear diagonal brace rod 42 are respectively connected to the side of the fixing plate 26 away from the connecting cross bar 11 through the front plate 22 of the leg and the rear plate 24 of the leg, such as the front diagonal brace rod 41 and the rear diagonal brace rod 42 are respectively threadedly connected to the side of the fixing plate 26 away from the connecting cross bar 11 through the front plate 22 of the leg and the rear plate 24 of the leg.

[0046] The front diagonal brace rod 41 passes through the support groove 210 at the connection between the left plate 21 of the support leg and the front plate 22 of the support leg, and the rear diagonal brace rod 42 passes through the support groove 210 at the connection between the left plate 21 of the support leg and the rear plate 24 of the support leg, wherein part of the front diagonal brace rod 41 is inserted into the support groove 210 at the connection between the left plate 21 of the support leg and the front plate 22 of the support leg, and part of the rear diagonal brace rod 42 is inserted into the support groove 210 at the connection between the left plate 21 of the support leg and the rear plate 24 of the support leg, so that the right diagonal brace connector 43 is connected to the side of the fixing plate 26 away from the connecting cross bar 11, such as the right diagonal brace connector 43 is threadedly connected to the fixing plate 26 away from the side of the connecting cross bar 11.

[0047] By adopting the above scheme, since part of the front diagonal support rod 41 and part of the rear diagonal support rod 42 in the left diagonal support member 4 and the right diagonal support member 5 are respectively inserted into the support groove 210 of the left support leg 2 and / or the right support leg 3, the front diagonal support rod 41 and the rear diagonal support rod 42 can be supported without occupying additional space of the left support leg 2 and the right support leg 3, thereby achieving the compactness of the support leg assembly 100.

[0048] In some optional embodiments, in combination Figure 1 and Figure 3 As shown, support plates 27 are respectively arranged between the left plate 21 of the leg and the front plate 22 of the leg, and between the left plate 21 of the leg and the rear plate 24 of the leg, and the support plates 27 correspond to the support grooves 210. The support plates 27 are used to support the front diagonal support rods 41 and the rear diagonal support rods 42. With the above scheme, the cabinet 200 is usually a rectangular structure, and the support plate 27 can act as a fulcrum, that is, the support plate 27 between the left plate 21 of the leg and the front plate 22 of the leg can be used as a fulcrum of the front diagonal support rod 41, and the support plate 27 between the left plate 21 of the leg and the rear plate 24 of the leg can be used as a fulcrum of the rear diagonal support rod 42, and the four vertices at the bottom of the cabinet are effectively supported by the lever principle. The support plate 27 can be directly fixedly connected to the position of the corresponding support groove 210 between the left leg plate 21 and the front plate 22 of the left leg 2 and / or the right leg 3. Specifically, the support plate 27 can be directly welded to the position of the corresponding support groove 210 between the left leg plate 21 and the front plate 22 of the leg in the left leg 2 and / or the right leg 3.

[0049] Optionally, combined Figure 1 and Figure 3As shown, the support plate 27 can be located on the inner wall between the left leg plate 21 and the front leg plate 22 and between the left leg plate 21 and the rear leg plate 24, and the support plate 27 is hidden in the left leg 2 and / or the right leg 3, which effectively utilizes the hollow structure 25 of the leg and improves the aesthetics of the leg assembly 100. The support plate 27 can be directly fixedly connected to the inner wall of the corresponding support groove 210 between the left leg plate 21 and the front leg plate 22 of the left leg 2 and / or the right leg 3. Specifically, the support plate 27 can be directly welded to the inner wall of the corresponding support groove 210 between the left leg plate 21 and the front leg plate 22 of the left leg 2 and / or the right leg 3.

[0050] The cross-sectional shape of the support plate 27 along the length direction of the cabinet connecting plate 44 can be rectangular, arc-shaped, trapezoidal, circular or fan-shaped. Of course, it can also be designed into other shapes according to actual needs, which is not specifically limited in this embodiment.

[0051] During specific use, first, the left leg 2 is assembled on one side of the connecting frame 1, so that one side of the connecting frame 1 is fixedly connected to the fixing plate 26 of the left leg 2 close to the connecting cross bar, and the right leg 3 is installed on the other side of the connecting frame 1, so that the other side of the connecting frame 1 is fixedly connected to the fixing plate 26 of the right leg 3 close to the connecting cross bar; secondly, the right diagonal support connecting member 43 in the left diagonal support member 4 is connected to the fixing plate 26 of the left leg 2 away from the connecting cross bar 11, and the right diagonal support connecting member 43 in the right diagonal support member 5 is connected to the fixing plate 26 of the right leg 3 away from the connecting cross bar; finally, the cabinet connecting plates 44 in the left diagonal support members 4 and the right diagonal support members 5 are connected to the bottom of the cabinet, and the leg device for supporting furniture assembled on the cabinet is directly placed on the ground for use, without the need to additionally design the wall and / or ground structure, thereby improving the assembly efficiency.

[0052] Of course, according to the actual situation, the above assembly sequence can be adjusted to:

[0053] First, the left leg 2 is assembled on one side of the connecting frame 1, so that one side of the connecting frame 1 is fixedly connected to the fixing plate 26 of the left leg 2 close to the connecting cross bar, and then the right diagonal support connecting member 43 in the left diagonal support member 4 is connected to the fixing plate 26 of the left leg 2 away from the connecting cross bar 11; secondly, the right leg 3 is installed on the other side of the connecting frame 1, so that the other side of the connecting frame 1 is fixedly connected to the fixing plate 26 of the right leg 3 close to the connecting cross bar, and the right diagonal support connecting member 43 in the right diagonal support member 5 is connected to the fixing plate 26 of the right leg 3 away from the connecting cross bar; finally, the cabinet connecting plates 44 in the left and right diagonal support members 4 and 5 are connected to the bottom of the cabinet, and the leg device for supporting furniture assembled on the cabinet is directly placed on the ground for use, without the need to additionally design the wall and / or ground structure, thereby improving the assembly efficiency.

[0054] According to actual conditions, the connecting frame 1, the left leg 2, the right leg 3, the left diagonal brace 4 and the right diagonal brace 5 can also be assembled in other ways. As long as the connecting frame 1, the left leg 2, the right leg 3, the left diagonal brace 4 and the right diagonal brace 5 can be assembled into a leg assembly 100, this embodiment does not make any specific limitations.
