[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 As shown, the present embodiment discloses a cross-fixed inner support for a direct-buried distribution box, including a center plate 1, and four folding components 2 are arranged in a cross shape on one side of the center plate 1. The folding component 2 includes a leg seat 201, and a length-adjustable support leg 202 is provided at the outer end of the leg seat 201. Ear plates 203 are provided on both sides of the leg seat 201, and the ear plates 203 are fixed on the center plate 1. The leg seat 201 is rotatably connected to the ear plates 203 on both sides through a leg shaft 204. A clamping block 205 is provided on the inner end side of the leg seat 201, and the two ends of the clamping block 205 are slidably connected to the ear plates 203 on both sides. The inner end of 201 is provided with a slot 206 which is engaged with the block 205. The block 205 is fixed with a guide slide column 207 on the side away from the leg seat 201. The guide slide column 207 is slidably connected in the reserved hole of the support block 208. The two ends of the support block 208 are fixed on the ear plates 203 on both sides. A spring 209 is sleeved on the guide slide column 207, one end of the spring 209 rests on the block 205, and the other end rests on the support block 208.

[0019] In this embodiment, the support leg 202 includes a side screw rod 202-1, which is coaxially fixed to the outer end of the leg base 201, and a sleeve 202-2 is threadedly connected to the side screw rod 202-1. The outer end of the sleeve 202-2 is rotatably connected to a side support plate 202-3, and the side support plate 202-3 supports the side wall of the distribution box. An operating rod 202-4 is fixed to the outer wall of the sleeve 202-2, and the sleeve 202-2 can be operated to rotate by the operating rod 202-4.

[0020] In this embodiment, a support rod 3 arranged perpendicularly to the center disk 1 is fixed on the side away from the folding component 2, and a middle support plate 4 is fixed on the end of the support rod 3, and the middle support plate 4 supports the bottom wall of the distribution box.

[0021] In this embodiment, the center disk 1 is in a cross shape.

[0022] The use process of the utility model is as follows:

[0023] When in use, the control block 205 slides backward and the leg seat 201 is rotated outward around the leg shaft 204. When the leg seat 201 rotates to be parallel to the center disk 1, the block 205 is released. The block 205 is inserted into the slot 206 at the inner end of the leg seat 201 under the action of the spring 209. In this way, the support leg 202 is unfolded and fixed. The utility model is placed in the distribution box. During the placement process, the middle support plate 4 is first placed against the bottom wall of the distribution box, and then the sleeve 202-2 is rotated to drive the side support plate 202-3 to rest against the side wall of the distribution box.

[0024] It should be noted that when the four supporting legs 202 are folded, their lengths need to be adjusted to avoid interference between the four side supporting plates 202 - 3 .

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
