[0041] When the bed of the utility model needs to be disassembled and stored:

[0042] Firstly, each support unit 2 can be unlocked by pressing the unlocking press portion 2310 inward, and then by rotating the upper end of the first leg assembly 22 inward (specifically, rotating the first upper leg 222 inward, and since the first upper leg 222 and the first lower leg 223 are connected together by the first support base 221, in actual operation, in order to facilitate operation, the first lower leg 223 can be rotated outward to rotate the first upper leg 222 inward), the beam 1 connected to the upper end of the first upper leg 222 (i.e. the beam 1 at the front end) can be rotated, and the bed surface 6 fitted on the two beams 1 can be converted from a taut state to a relaxed state, at this time, the two beams 1 and the bed surface 6 can be easily disassembled from the upper ends of the first upper leg 222 and the second upper leg 242.

[0043] Secondly, after the two beams 1 and the bed surface 6 are disassembled from the upper ends of the first upper leg 222 and the second upper leg 242, on the one hand, the bed surface 6 can be disassembled from the two beams 1, and the disassembled bed surface 6 can be rolled up, and the disassembled beam 1 can be disassembled into multiple sections for storage, on the other hand, the first upper leg 222 can be disassembled from the first support base 221 and hung on the first hanging column 511 by the first buckle 2221 for storage, the second upper leg 242 can be disassembled from the first support base 241 and hung on the second hanging column 521 by the second buckle 2421 for storage, the first lower leg 223 can be disassembled from the first support base 221 and sleeved into the first clasp 512 for storage, and the second lower leg 243 can be disassembled from the second support base 241 and sleeved into the second clasp 522 for storage, thereby greatly reducing the storage volume of the bed, which is very beneficial for carrying and storing outside.

[0044] The bed provided by the utility model is installed, the bed surface 6 is sleeved on the two cross beams 1 in advance, then the two cross beams 1 sleeved with the bed surface 6 are installed with the upper end of the second upper supporting leg 242 and the upper end of the first upper supporting leg 222 in each supporting unit 2, simultaneously, in order to be convenient for installation, when the cross beam 1 located at the front end is installed on the upper end of the first upper supporting leg 222, the first upper supporting leg 222 can be rotated at a certain angle inwards and the second locking buckle part 2211 is located below the first locking buckle part 2311 before installation, then the first upper supporting leg 222 is rotated outwards, the first buckle 2221 on the upper end of the first upper supporting leg 222 is sleeved on the corresponding position of the cross beam 1 located at the front end to realize installation, and in the process, the first supporting base 221 is rotated upwards (it can also be understood as being rotated outwards clockwise) along with the outward rotation of the first upper supporting leg 222, the guiding arc surface 2212 is abutted against the guiding inclined surface 2312 to make the locking base 231 slide in the unlocking direction L1, until the first upper supporting leg 222 is rotated outwards to the right position, at this moment, the guiding arc surface 2212 just passes the first locking buckle part 2311, then the locking base 231 is reset in the locking direction L2 under the action of the two reset springs 232, and then the first locking buckle part 2311 is automatically clamped into the second locking buckle part 2211 to realize locking.

[0045] The above is only the preferred embodiment of the utility model, and cannot limit the range of the utility model, that is, the simple equivalent changes and modifications made according to the patent application range and the utility model description content still belong to the range covered by the utility model patent.
