In some embodiments, referring to fig. 5, 7 and 10, the stopper 340 is provided with an opening 360 penetrating in the front-rear direction, and one end of the longitudinal beam 200 is inserted into the opening 360.

In this embodiment, a fifth boss is disposed at an end of the longitudinal beam 200 close to the second through slot 320, the user inserts the fifth boss into the opening 360 while abutting the longitudinal beam 200 against the stopper 340, after locking a fixing member such as a screw or a rivet for the longitudinal beam 200, except that the fixing member can limit the longitudinal beam 200 in the up-down direction, the cooperation of the fifth boss and the opening 360 can also limit the longitudinal beam 200 in the up-down direction, when the longitudinal beam 200 is stressed in the up-down direction, the cooperation of the fifth boss and the opening 360 can share the stress of the fixing member, thereby preventing the longitudinal beam 200 from being separated from the support bracket 300 due to the damage of the fixing member caused by the concentrated application of an external force on the fixing member.

In some embodiments, the support rod 400 is coupled to the support bracket 300 by a removable connection. In this embodiment, the detachable supporting rod 400 is convenient for separate loading and is beneficial to transportation. The detachable connection means includes, but is not limited to, a screw connection, a key connection, a pin connection, a magnetic connection, and the like, which can freely separate and couple the support bar 400 from the support bracket 300.

In some preferred embodiments, referring to fig. 5, 6 and 7, the support bracket 300 is provided with a first boss 370, the first boss 370 is located right below the first through groove 310, and the first boss 370 is provided with a second groove 371 extending in the left-right direction and penetrating through the bottom surface of the first boss 370;

the top surface of the support rod 400 is provided with a second protrusion 410, and the second protrusion 410 is inserted into the second groove 371 to connect the support rod 400 with the support bracket 300.

In this embodiment, the support rod 400 is connected to the support bracket 300 by embedding, so that the assembly and disassembly processes are simple and convenient.

In a further embodiment, referring to fig. 5, fig. 6, fig. 7, fig. 8 and fig. 9, the inner wall surfaces of the front and rear sides of the second groove 371 are provided with third grooves 372 extending in the front-rear direction, and one side of the third grooves 372 close to the notches of the second groove 371 is provided with third bosses 373 extending in the up-down direction;

the second boss 410 is provided with a sliding groove 411 extending in the front-rear direction, and the sliding groove 411 is communicated with the third groove 372;

the bed frame center connection structure further comprises a locking block 500, the locking block 500 can slide on the sliding groove 411 and is embedded into the third groove 372, and the length of the locking block 500 in the front-back direction is greater than the depth of the third groove 372.

In this embodiment, the third groove 372 and the sliding groove 411 are disposed on the side of the notch facing the left and right direction of the second groove 371, and after the second protrusion 410 is inserted into the second groove 371, the third groove 372 and the sliding groove 411 are communicated with each other, and at this time, the supporting rod 400 is not limited in the left and right direction, so that the supporting rod 400 may still be separated from the supporting bracket 300 when being subjected to an external force. In order to avoid the above situation, by inserting the locking block 500 into the third groove 372, the length of the locking block 500 is greater than the depth of the third groove 372, so that the locking block 500 can protrude out of the third groove 372 and abut against the sliding groove 411 to limit the supporting rod 400 in the left-right direction.

It should be noted that, since the third protrusion 373 protrudes in the vertical direction, after the locking block 500 is inserted into the third groove 372, the movement of the locking block 500 in the left-right direction is blocked by the third protrusion 373, the locking block 500 cannot move in the left-right direction, and the support rod 400 is locked accordingly.

In some embodiments, referring to fig. 6, through holes 374 are further formed at front and rear sides of the second groove 371 to pass through in the front and rear direction, and the through holes 374 communicate with the third groove 372. In practice, the user can insert a thin needle with a diameter smaller than the through hole 374 into the through hole 374 to eject the locking block 500 out of the third groove 372, thereby unlocking the support rod 400.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be limited by the above-mentioned scope.
