a rectangular frame,

a plurality of frame rods, and

at least two and no more than three longitudinal beams, wherein:

the rectangular frame comprises two transverse rods symmetrically parallel to each other in a front-and-rear direction and two longitudinal rods symmetrically parallel to each other in a left-and-right direction,

a length of each of the two transverse rods is greater than a length of each of the two longitudinal rods,

the at least two and no more than three longitudinal beams divide the rectangular frame into three or four individual cells,

the plurality of frame rods are evenly disposed in the three or four individual cells,

each of the plurality of frame rods is arranged transversely,

two ends of corresponding ones of the plurality of frame rods in a row are connected to one side of a first one of the two longitudinal rods, two sides of the at least two and no more than three longitudinal beams, one side of a second one of the two longitudinal rods in sequence.

2. The bed skeleton of an iron frame bed according to claim 1 , wherein:

an inner side of each of the two transverse rods is disposed with one or more U-shaped seats,

each end of each of the at least two and no more than three longitudinal beams is supported on a corresponding one of the one or more U-shaped seats, and

each end of each of the at least two and no more than three longitudinal beams and the corresponding one of the one or more U-shaped seats are detachably buckled to each other.

3. The bed skeleton of an iron frame bed according to claim 2 , wherein:

a left inner side and a right inner side of each of the one or more U-shaped seats respectively comprise a protruding tongue,

a left side and a right side of each end of each of the at least two and no more than three longitudinal beams respectively comprise a buckle hole, and

the protruding tongue is configured to be disposed in the buckle hole.

4. The bed skeleton of an iron frame bed according to claim 3 , wherein:

a bottom surface of each of the one or more U-shaped seats comprises a position-limiting block,

the position-limiting block is configured to be disposed in the position-limiting hole.

6. The bed skeleton of an iron frame bed according to claim 1 , wherein:

each end of each of the plurality of frame rods is folded down vertically to form a vertical hook,

each of the two longitudinal rods and each of the at least two and no more than three longitudinal beams comprise insertion holes, and

the vertical hook is configured to be disposed in a corresponding one of the insertion holes.

7. The bed skeleton of an iron frame bed according to claim 6 , wherein:

each end of each of the plurality of frame rods is flattened and folded down to form the vertical hook,

a plastic buckle is disposed in each of the insertion holes,

the plastic buckle comprises one or more slots, and

the vertical hook is configured to be disposed in a corresponding one of the one or more slots.

8. The bed skeleton of an iron frame bed according to claim 7 , wherein:

the one or more slots of the plastic buckle disposed on a corresponding one of the at least two and no more than three longitudinal beams comprise two slots.

9. The bed skeleton of an iron frame bed according to claim 7 , wherein:

an anti-releasing structure is disposed between the vertical hook and the plastic buckle.

10. The bed skeleton of an iron frame bed according to claim 9 , wherein:

the one or more slots of the plastic buckle disposed on a corresponding one of the at least two and no more than three longitudinal beams comprise two slots.

11. The bed skeleton of an iron frame bed according to claim 1 , wherein:

each end of each of the two transverse rods and each end of each of the two longitudinal rods are directly connected to each other, or

each end of each of the two transverse rods and each end of each of the two longitudinal rods are transitionally connected to each other through an upright column.
