[0028] In combination with the appended Figure 1-8 drawings, a foldable storage rack frame of this embodiment includes a first support base 1, a second support base 2, and a folding rod assembly 3 disposed between the first support base 1 and the second support base 2. The first support base 1 and the second support base 2 of this embodiment are both quadrilateral structures, and four groups of folding rod assemblies 3 are provided between the first support base 1 and the second support base 2. In this embodiment, a drawer 6 is provided between the first support base 1 and the second support base 2. In other embodiments, the first support base 1 is provided with a storage board on which items can be directly placed. Specifically in application, multiple layers of support bases can be provided.

[0029] The folding rod assembly 3 includes a first folding rod 31 and a second folding rod 32. The first folding rod 31 is rotatably connected to the first support base 1, and the second folding rod 32 is rotatably connected to the second support base 2. Specifically in application, the first folding rod 31 is pivotally connected to the first support base 1, and the second folding rod 32 is pivotally connected to the second support base 2. In other embodiments, the pivotal connection can be replaced by a pin or a bolt or a hinge connection. Since the first folding rod 31 and the second folding rod 32 need to have a certain strength during support, they will have a certain thickness after forming. If the first folding rod 31 and the second folding rod 32 are directly pivotally connected, they will interfere with each other during folding. Therefore, an anti-interference member 4 is provided between the first folding rod 31 and the second folding rod 32 to prevent interference when the first folding rod 31 and the second folding rod 32 are folded relative to each other. The first folding rod 31 is rotatably connected to the anti-interference member 4, and the second folding rod 32 is rotatably connected to the anti-interference member 4. Specifically in application, the first folding rod 31 is pivotally connected to the anti-interference member 4, and the second folding rod 32 is pivotally connected to the anti-interference member 4. In other embodiments, the pivotal connection can be replaced by a pin or a bolt connection. In this embodiment, the first folding rod 31 is provided with a first avoidance recess 311 for placing the anti-interference member 4, and the second folding rod 32 is provided with a second avoidance recess 321 for placing the anti-interference member 4. When the first folding rod 31 and the second folding rod 32 are opened relative to each other, the anti-interference member 4 is placed in the first avoidance recess 311 and the second avoidance recess 321. In other embodiments, the first folding rod 31 and the second folding rod 32 may not be provided with the first avoidance recess 311 and the second avoidance recess 321.

[0030] When the first folding rod 31 and the second folding rod 32 are folded relative to each other, the anti-interference member 4 is perpendicular to the first folding rod 31 and the second folding rod 32. When the first folding rod 31 and the second folding rod 32 are unfolded relative to each other, the anti-interference member 4 is parallel to the first folding rod 31 and the second folding rod 32.

[0031] One of the first folding rod 31 and the anti-interference member 4 is provided with a first hole and groove structure 41, and the other is provided with a first shaft 312 that cooperates with the first hole and groove structure 41. One of the second folding rod 32 and the anti-interference member 4 is provided with a second hole and groove structure 42, and the other is provided with a second shaft 322 that cooperates with the second hole and groove structure 42. In specific applications, the first hole and groove structure 41 is provided on the anti-interference member 4, the first shaft 312 is provided on the first folding rod 31, the second hole and groove structure 42 is provided on the anti-interference member 4, and the second shaft 322 is provided on the second folding rod 32. Both the first hole and groove structure 41 and the second hole and groove structure 42 are strip-shaped. When the first folding rod 31 and the second folding rod 32 are in the unfolded state, the first shaft 312 abuts against one end of the first hole and groove structure 41, and the second shaft 322 abuts against one end of the second hole and groove structure 42. Then, by pulling the first folding rod 31 and the second folding rod 32, when the first shaft 312 slides to the other end of the first hole and groove structure 41 and the second shaft 322 slides to the other end of the second hole and groove structure 42, at this time, the first folding rod 31 and the second folding rod 32 are pulled apart by a certain distance, and then the first folding rod 31 and the second folding rod 32 are folded, and the anti-interference member 4 is perpendicular to the first folding rod 31 and the second folding rod 32. In this embodiment, the first shaft 312 is provided on the side wall of the first avoidance recess 311, the second shaft 322 is provided on the side wall of the second avoidance recess 321, and the first hole and groove structure 41 and the second hole and groove structure 42 are correspondingly provided on the side surface of the anti-interference member 4. Since the anti-interference member 4 is provided between the two first shafts 312 and between the two second shafts 322, the first shaft 312 and the second shaft 322 are not easily disengaged during use.

[0032] In order to enable the first folding rod 31 and the second folding rod 32 to play a supporting role after being unfolded, the first folding rod 31 and the second folding rod 32 are snap-connected after being unfolded, and / or, the first folding rod 31 and the anti-interference member 4 are snap-connected, and / or, the second folding rod 32 and the anti-interference member 4 are snap-connected. In specific applications, the first folding rod 31 is provided with a first snap-connection hole 313, and the anti-interference member 4 is provided with a first snap-connection shaft 43 that cooperates with the first snap-connection hole 313; and / or, the second folding rod 32 is provided with a second snap-connection hole 323, and the anti-interference member 4 is provided with a second snap-connection shaft 44 that cooperates with the second snap-connection hole 323; and / or, the second folding rod 32 is provided with a third snap-connection hole 324, and the first folding rod 31 is provided with a third snap-connection shaft 314 that cooperates with the third snap-connection hole 324. In this embodiment, the first folding rod 31 is provided with a first snap-connection hole 313, and the anti-interference member 4 is provided with a first snap-connection shaft 43 that cooperates with the first snap-connection hole 313; the second folding rod 32 is provided with a second snap-connection hole 323, and the anti-interference member 4 is provided with a second snap-connection shaft 44 that cooperates with the second snap-connection hole 323; the second folding rod 32 is provided with a third snap-connection hole 324, and the first folding rod 31 is provided with a third snap-connection shaft 314 that cooperates with the third snap-connection hole 324. In other embodiments, the snap-connection shaft can be a snap projection, and the snap-connection hole can be a snap groove.

[0033] In this embodiment, the first clamping hole 313, the second clamping hole 323 and the third clamping hole 324 have the same structure. The inner surface of the clamping hole is inclined so that one end of the clamping hole has a larger aperture and the other end has a smaller aperture. The end with the larger aperture is the insertion end for the clamping shaft. The first clamping shaft 43, the second clamping shaft 44 and the third clamping shaft 314 have the same structure. The surface of the clamping shaft is inclined so that the shaft diameter of the clamping shaft gradually decreases from the root to its end. Such a setting enables the clamping shaft to be easily inserted into the clamping hole.

[0034] The first support base 1 / second support base 2 is rotatably connected with a support rod 5 for supporting the unfolded states of the first folding rod 31 and the second folding rod 32. After the support rod 5 is unfolded, it is respectively clamped with the first folding rod 31 and the second folding rod 32. In specific applications, the support rod 5 is provided with a first clamping protrusion 51, a second clamping protrusion 52 and a third clamping protrusion 53. The first folding rod 31 is provided with a first clamping groove 315 that cooperates with the first clamping protrusion 51. The anti-interference member 4 is provided with a second clamping groove 45 that cooperates with the second clamping protrusion 52. The second folding rod 32 is provided with a third clamping groove 325 that cooperates with the third clamping protrusion 53. Both the first clamping protrusion 51 and the third clamping protrusion 53 are provided with small clamping protrusions 7, and the first clamping groove 315 and the third clamping groove 325 are correspondingly provided with small clamping grooves 8. In specific applications, the first support base 1 / second support base 2 and the support rod 5 are connected by shaft connection or pin connection or bolt connection or hinge connection.

[0035] A first reinforcing rib 316 is formed between the first avoidance recess 311 and the first clamping groove 315. A second reinforcing rib 326 is formed between the second avoidance recess 321 and the third clamping groove 325. The second clamping groove 45 makes the anti-interference member 4 have a thin-wall structure. When the support rod 5 is respectively clamped with the first folding rod 31 and the second folding rod 32, the first reinforcing rib 316 and the thin-wall structure at the lower part of the anti-interference member 4 are clamped between the first clamping protrusion 51 and the second clamping protrusion 52. The second reinforcing rib 326 and the thin-wall structure at the upper part of the anti-interference member 4 are clamped between the second clamping protrusion 52 and the third clamping protrusion 53. Thereby, the supporting effect after the first folding rod 31 and the second folding rod 32 are unfolded can be further strengthened.

[0036] The rotation axis direction of the support rod 5, the rotation axis direction of the first folding rod 31 and the rotation axis direction of the second folding rod 32 are relatively parallel.

[0037] An inner recess 317 is provided on the side of the first folding rod 31 or the second folding rod 32. The inner recess 317 makes the edge of the support rod 5 protrude, so as to facilitate pinching the support rod 5 when separating the support rod 5 from the folding rod assembly 3. When the support rod 5 is rotatably connected to the first support base 1, the inner recess 317 is provided at one end of the second folding rod 32 away from the first support base 1. When the support rod 5 is rotatably connected to the second support base 2, the inner recess 317 is provided at one end of the first folding rod 31 away from the second support base 2. So as to save effort when separating the support rod 5 from the folding rod assembly 3.

[0038] The first support base 1 is provided with a first limiting portion 11 for preventing the drawer 6 from being pushed backward beyond the limit, and the second support base 2 is provided with a second limiting portion 21 for preventing the drawer 6 from being pulled out beyond the limit. The bottom of the drawer 6 is provided with rear rollers 61, and the first support base 1 is provided with a running wheel groove 12 for placing the rear rollers 61. When the drawer 6 is pushed backward in place, the rear rollers 61 are received in the running wheel groove 12.
