The second locking member 420 is arranged on the second fixing member 120 and is configured to be able to connect with the moving member 220 or the second end of the connecting member 210.

[0041] In the practical application of the support frame assembly 10, taking the height direction of the box body 20 as the vertical direction, both the first fixing member 110 and the second fixing member 120 are arranged along the vertical direction.

[0042] Specifically, when the connecting member 210 and the supporting member 310 are in a relatively unfolded state, the first end of the connecting member 210 is movably connected to the first fixing member 110, the second end of the connecting member 210 is fixedly connected to the movable member 220 on one side perpendicular to the vertical direction, the first end of the supporting member 310 is movably connected to the second fixing member 120, and the second end of the supporting member 310 is fixedly connected to the movable member 220 on one side perpendicular to the vertical direction, so that the support frame assembly 10 supports the box body 20.

[0043] When the connecting member 210 and the supporting member 310 are in a relatively contracted state, the first end of the connecting member 210 is movably connected to the first fixing member 110, the second end of the connecting member 210 is locked to the second locking member 420 on one side perpendicular to the vertical direction, the first end of the supporting member 310 is movably connected to the second fixing member 120, and the second end of the supporting member 310 is locked to the first locking member 410 on one side perpendicular to the vertical direction, so that the support frame assembly 10 is received in the box body 20.

[0044] In the support frame assembly 10 of the embodiment of the present application, by arranging the cooperation of the moving mechanism 200 and the supporting mechanism 300, specifically, the first end of the connecting member 210 in the moving mechanism 200 is movably connected to the first fixing member 110 in the fixing mechanism 100, the movable member 220 in the moving mechanism 200 is arranged at the second end of the connecting member 210. At the same time, the first end of the supporting member 310 in the supporting mechanism 300 is movably connected to the second fixing member 120 in the fixing mechanism 100, and the second end of the supporting member 310 is configured to be able to be connected to the movable member 220. In this way, the connecting member 210 and the supporting member 310 are relatively unfolded and are respectively connected to the movable member 220 to form a stable triangular connection structure. When it is necessary to retract the support frame assembly 10, only need to separate the second end of the supporting member 310 from the movable member 220, so that the connecting member 210 and the supporting member 310 are relatively retracted, and the first locking member 410 arranged on the first fixing member 110 is used to lock the supporting member 310, and the second locking member 420 arranged on the second fixing member 120 is used to lock the movable member 220 or the connecting member 210. In this way, the moving mechanism 200 and the supporting mechanism 300 can be firmly connected to the box body 20, reducing the space occupied by the support frame assembly 10, so that the storage of the support frame assembly 10 is more time-saving and labor-saving, and the use of the support frame assembly 10 is more convenient.

[0045] In some embodiments, optionally, the second end of the support member 310 is configured to be capable of being snap-connected to the movable member 220; the first locking member 410 is configured to be capable of being snap-connected to the second end of the support member 310. With such an arrangement, the second end of the support member 310 can be snap-connected to both the movable member 220 and the first locking member 410, facilitating the connection and disassembly of the support member 310. By snap-connecting the second end of the support member 310 to the movable member 220, the support frame assembly 10 is in an unfolded state, or by snap-connecting the second end of the support member 310 to the first locking member 410, the support frame assembly 10 is in a retracted state, facilitating the switching of the state of the support frame assembly 10.

[0046] In some embodiments, optionally, the movable mechanism 200 further includes a first sleeve 230 disposed at the second end of the connecting member 210. A first card slot 221 matching the first sleeve 230 is provided on the movable member 220, and the first sleeve 230 is sleeved in the first card slot 221; the support mechanism 300 further includes a card joint 320 disposed at the second end of the support member 310. A second card slot 222 matching the card joint 320 is provided on the movable member 220, and the card joint 320 is configured to be capable of being snap-connected to the second card slot 222.

[0047] In application, the first fixing member 110, the second fixing member 120, and the movable member 220 are arranged parallel to each other. The support frame assembly 10 is supported on the ground by the movable member 220. The connecting member 210 is disposed perpendicular to the movable member 220. The connecting member 210 is connected to the movable member 220 through the first sleeve 230, which can ensure the uniform stress of the support frame assembly 10. The support member 310 can also be disposed perpendicular to the movable member 220. The support member 310 is connected to the movable member 220 through the card joint 320 to prevent the support frame assembly 10 from tipping over. By utilizing the cooperation of the first sleeve 230 and the first card slot 221 to achieve the mutual connection between the connecting member 210 and the movable member 220, the structure is simple, facilitating the relative movement between the connecting member 210 and the movable member 220. By utilizing the cooperation of the card joint 320 and the second card slot 222 to achieve the mutual connection between the support member 310 and the movable member 220, the structure is simple, facilitating the relative movement between the support member 310 and the movable member 220, and also facilitating the removal of the second end of the support member 310 from the movable member 220, which is convenient to use.

[0048] In some embodiments, optionally, the movable mechanism 200 includes two connecting members 210. Two first card slots 221 corresponding to the first sleeves 230 on the two connecting members 210 are provided on the movable member 220. Along the extending direction of the movable member 220, the two first card slots 221 are respectively located on opposite sides of the second card slot 222. With such a design, the two connecting members 210 in the movable mechanism 200 and the support member 310 in the support mechanism 300 can be arranged in an interleaved manner, which can not only increase the connection stability between the movable mechanism 200 and the support mechanism 300, but also facilitate the relative expansion and retraction between the connecting member 210 and the support member 310, thus making the storage of the support frame assembly 10 convenient.

[0049] Please combine Figure 2 and Figure 3 and refer to Figure 4 and Figure 5 In some embodiments, optionally, the card joint 320 includes a card joint body 321 and a card joint ring 322. An annular groove 3211 is provided in the card joint body 321. A card joint opening 3212 communicating with the annular groove 3211 is further provided on one side of the card joint body 321. The card joint ring 322 is movably connected to the card joint body 321 so that the card joint ring 322 can block or expose the card joint opening 3212 during the relative movement with respect to the card joint body 321. With such a design, when it is necessary to connect and fix the support member 310 to the movable member 220, the relative movement between the card joint ring 322 and the card joint body 321 can be used to firmly connect the card joint 320 to the second slot of the movable member 220. When it is necessary to remove the second end of the support member 310 from the movable member 220, the relative movement between the card joint ring 322 and the card joint body 321 can also be used to disengage the card joint 320 from the movable member 220, making the installation and disassembly more convenient.

[0050] Such as Figure 5As shown, in some embodiments, optionally, the card connector 320 further includes an extension portion 323, a card connection handle 324, a first mounting rod 325, a second mounting rod 326, a first torsion spring 327, and a second torsion spring 328. The extension portion 323 is connected to the card connection body 321. An accommodation groove 3231 communicating with the annular groove 3211 is provided in the extension portion 323. The first mounting rod 325 and the second mounting rod 326 are spaced apart from each other and disposed in the accommodation groove 3231. The first torsion spring 327 is sleeved on the first mounting rod 325, and the first end of the first torsion spring 327 abuts against the inner wall of the extension portion 323. The second torsion spring 328 is sleeved on the second mounting rod 326, and the first end of the second torsion spring 328 abuts against the inner wall of the extension portion 323. The card connection ring 322 is sleeved on the first mounting rod 325, and the card connection ring 322 abuts against the second end of the first torsion spring 327. The card connection handle 324 is connected to the card connection ring 322. The card connection handle 324 is sleeved on the second mounting rod 326, and the card connection handle 324 abuts against the second end of the second torsion spring 328. With such a setting, the card connection ring 322 can be driven to move relative to the card connection body 321 by means of the card connection handle 324, which is convenient for adjusting the card connection state of the card connector 320. At the same time, the settings of the first torsion spring 327 and the second torsion spring 328 also enable the card connector 320 to be more firmly fixed on the movable member 220.

[0051] In application, the annular groove 3211 on the card connection body 321 allows the movable member 220 or the second sleeve 411 to pass through. By applying an external force to the card connection handle 324, the operator can drive the card connection ring 322 to rotate, so as to change the position of the card connection ring 322 relative to the card connection body 321, so that the card connection ring 322 can block or expose the card connection opening 3212 during the process of moving relative to the card connection body 321, facilitating the entry and exit of the movable member 220 or the second sleeve 411 from the annular groove 3211.
