Expansion connection structure of split bed

Abstract

This invention discloses an expansion connection structure for a split bed, relating to the field of split bed technology. The expansion connection structure includes a first connecting block and a second connecting block. The second connecting block is slidably disposed on the upper side of the first connecting block with a wedge. The connecting member includes at least a first sidewall and a second sidewall. The first sidewall is fixedly connected to the bottom of the bed body, and the second sidewall is disposed below the first sidewall. The first connecting block and the second connecting block span at least two bed bodies. The first connecting block can move closer to or away from the second sidewall. When moving closer, the first connecting block and the second sidewalls of at least two connecting members together abut against the wedge of the second connecting block and slide upward. The rising second connecting block can abut against and support the lower part of the first sidewalls of at least two connecting members. This invention can abut against and support the connection point of the connecting member, preventing the entire connecting member from concave and bending downward at the connection point.

Claims

1. An expansion connection structure for a split-type bed, the split-type bed having at least two bed frames, each bed frame having a connector at its bottom, the connectors under each bed frame being connected by the expansion connection structure, thereby splicing at least two bed frames into a whole, wherein: The expansion connection structure includes a first connecting block and a second connecting block. The second connecting block is slidably disposed on the upper side of the first connecting block. The connector includes at least a first sidewall and a second sidewall. The first sidewall is fixedly connected to the bottom of the bed body, and the second sidewall is disposed on the lower side of the first sidewall. The first connecting block and the second connecting block span at least two bed bodies. The first connecting block can move closer to or away from the second sidewall. When moving closer, the first connecting block and the second sidewalls of at least two connectors slide upward against the wedge of the second connecting block. The rising second connecting block can be supported upward against the lower sidewall of the first sidewall of at least two connectors.

2. The expansion connection structure of the split bed as described in claim 1, wherein: The connector also includes a third sidewall, which is disposed below the second sidewall. The expansion connection structure also includes a third connecting block, which is slidably disposed below the first connecting block. The third connecting block spans at least the third sidewalls of the two bed connectors. When the first connecting block is close to the second sidewall, the first connecting block and the second sidewalls of at least two connectors can jointly abut against the wedge of the third connecting block and slide down, so that the third connecting block abuts against the upper part of the third sidewalls of at least two connectors.

3. The expansion connection structure of the split bed as described in claim 2, wherein: The bed has two frames that can be joined together to form a whole. An expansion connection structure spans the connectors of the two frames. The first connecting block spans the second sidewall of the two connectors. The second connecting block simultaneously abuts against the lower part of the first sidewall of the two connectors, and the third connecting block simultaneously abuts against the upper part of the third sidewall of the two connectors.

4. The expansion connection structure of the split bed as described in claim 1 or 2, wherein: The expansion connection structure also includes a locking component, which can drive the first connecting block to move closer to or further away from the second sidewall. It can also connect the first connecting block to the second sidewall of at least two connectors at the same time, and when the second connecting block is abutted against and supported under the first sidewall of at least two connectors, the locking component can lock the movement of the first connecting block.

5. The expansion connection structure of the split bed as described in claim 4, wherein: The locking component includes locking bolts and threaded holes. Multiple threaded holes are provided on the first connecting block and are spaced apart along the length of the first connecting block. When the first connecting block spans at least two connecting members, the multiple threaded holes are distributed within the range of the second sidewalls of at least two connecting members. Multiple locking bolts pass through the second sidewalls and are screwed into the threaded holes one by one, thereby simultaneously screwing the first connecting block onto at least two second sidewalls. When the locking bolts rotate in the direction of screwing into the threaded holes, they can drive the first connecting block to move closer to the second sidewalls, and vice versa.

6. The expansion connection structure of the split bed as described in claim 2, wherein: The first connecting block has an upward-sloping first inclined surface on its upper side and a downward-sloping second inclined surface on its lower side. The second connecting block has a third inclined surface on its lower side that matches the first inclined surface. The third inclined surface wedges into the first inclined surface. The third connecting block has a fourth inclined surface on its upper side that matches the second inclined surface. The fourth inclined surface wedges into the second inclined surface.

7. The expansion connection structure of the split bed as described in claim 6, wherein: The second connecting block has a first strip hole along its sliding direction. The second connecting block is screwed onto the first inclined surface after the first bolt passes through the first strip hole. When the second connecting block slides on the first connecting block, the first bolt can guide the sliding of the second connecting block. The third connecting block has a second strip hole along its sliding direction. The third connecting block is screwed onto the second inclined surface after the second bolt passes through the second strip hole. When the third connecting block slides on the first connecting block, the second bolt can guide the sliding of the third connecting block.

8. The expansion connection structure of the split bed as described in claim 6, wherein: The first connecting block has an isosceles trapezoidal cross section, with its upper base facing the second side wall and its two sides facing the first and third side walls respectively. The second and third connecting blocks have right-angled triangle cross sections. The hypotenuse of the second connecting block is fitted onto the side of the first connecting block facing the first side wall, and the hypotenuse of the third connecting block is fitted onto the side of the first connecting block facing the third side wall.

9. The expansion connection structure of the split bed as described in claim 2, wherein: The connector is tubular.

10. The expansion connection structure of the split bed as described in claim 9, wherein: The tubular connector has a rectangular cross-section. The top wall of the tubular connector is the first side wall, the bottom wall of the tubular connector is the third side wall, and any side wall adjacent to the top wall of the tubular connector is the second side wall.
