[0028] In this embodiment, the fireproof cloth bag is made of fireproof cloth. The upper portion of the fireproof cloth bag 1 forms a bag opening. The opposite ends of the bag opening are respectively mounted on the opposite ends of the opening frame 2, and the middle portion of the bag opening is mounted on the middle portion of the opening frame 2.
[0029] The support frame 2 includes two fixed tubes 21 arranged opposite to each other and a telescopic assembly 22 connected between the ends of the two fixed tubes 21 .
[0030] The length of the telescopic component is adjustable. When in use, the length of the support frame is adjusted by the telescopic component, such as Figure 1 The state shown is when the fireproof cloth bag is closed (i.e. the length of the telescopic component is the shortest). At this time, the fireproof cloth bag has the smallest volume after the middle part is folded. Figure 2 The fireproof cloth bag is in the unfolded state shown (i.e. the length of the telescopic component is the longest). At this time, the fireproof cloth bag is fully unfolded, and its volume and floor space are the largest.
[0031] In this embodiment, the telescopic assembly 22 includes an inner sleeve 221, a middle sleeve 222, and an outer sleeve 223. The inner sleeve 221, the middle sleeve 222, and the outer sleeve 223 are movably connected together in sequence.
[0032] Specifically, the inner sleeve 221, the middle sleeve 222 and the outer sleeve 223 respectively have an open end and a closed end.
[0033] The closed end of the outer sleeve 223 is connected to the end of a fixed tube 21. The open end of the outer sleeve 223 is movably sleeved on the closed end of the middle sleeve 222.
[0034] The open end of the middle sleeve 222 is movably sleeved on the closed end of the inner sleeve 221 .
[0035] The open end of the inner sleeve 221 is connected to one end of the other fixing tube 21. The closed end of the inner sleeve 221 is provided with a first locking hole.
[0036] The two ends of the middle sleeve 222 are respectively provided with a first insertion hole. The first insertion hole of the closed end of the middle sleeve 222 is aligned with the first locking hole. The closed end of the middle sleeve 222 is provided with a second locking hole.
