Abstract

An assembly structure for a bed column and a lateral bed rod is provided. The bed column is arranged vertically and comprises an upper column and a lower column. The lower column comprises a joint section. The upper column is sleeved on the joint section and is stopped at a positioning step formed at a bottom end of the joint section. The lateral bed rod is horizontally, laterally arranged. The lateral bed rod is connected with a locking piece adjacent to a side of the positioning step and abutting the upper column and the lower column. A first portion of the locking piece is locked with an upper bolt enabling the locking piece, the upper column, and the joint section to be locked together. A second portion of the locking piece is locked with a lower bolt enabling the locking piece and the lower column to be locked together.

First claim

What is claimed is:

1. An assembly structure for a bed column and a lateral bed rod, wherein:
the bed column is arranged vertically and comprises an upper column and a lower column that are configured to be inserted together in an up-and-down direction,
an upper end of the lower column comprises a joint section formed by reducing a diameter of the upper end of the lower column,
a positioning step is formed at a bottom end of the joint section,
the positioning step is disposed no lower than an upper surface of the lateral bed rod,
the upper column is sleeved on the joint section from top to bottom and is stopped at the positioning step,
the lateral bed rod is horizontally, laterally arranged,
an end surface of the lateral bed rod is connected with a locking piece,
the locking piece is adjacent to a side of the positioning step and abuts an outer side of the upper column and an outer side of the lower column,
a first portion of the locking piece that extends upward beyond the upper surface of the lateral bed rod is locked with an upper bolt,
the upper bolt enables the locking piece, the upper column, and the joint section to be locked together,
a second portion of the locking piece that extends downward beyond a lower surface of the lateral bed rod is locked with a lower bolt,
the lower bolt enables the locking piece and the lower column to be locked together,
the upper column is locked with a reinforcing bolt,
the reinforcing bolt enables the upper column and the joint section to be locked together in absence of the lower column, and
the reinforcing bolt is located above the upper bolt.

2. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the reinforcing bolt, the upper bolt, and the lower bolt are arranged in a straight line.

3. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the lower column is disposed with pull rivets respectively corresponding to the upper bolt and the lower bolt.

4. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the lower column is disposed with a pull rivet corresponding to the reinforcing bolt.

5. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the locking piece is arc-shaped to correspond to a shape of the outer side of the upper column and a shape of the outer side of the lower column.

6. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
a left side and a right side of the locking piece respectively comprises a folded edge folded toward the lateral bed rod.

7. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the locking piece is welded with the lateral bed rod.

8. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the upper surface of the lateral bed rod is flush with the positioning step.

9. The assembly structure for the bed column and the lateral bed rod according to claim 1 , wherein:
the lower column is fixedly connected to a longitudinal bed rod.

10. The assembly structure for the bed column and the lateral bed rod according to claim 5 , wherein:
a left side and a right side of the locking piece respectively comprises a folded edge folded toward the lateral bed rod.
