[0019] The utility model will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] like Figure 1 As shown, the utility model provides a temporary building expansion device, including: a plurality of support frames 1, a frame 4 is arranged between adjacent support frames 1, each side of the frame 4 is connected to the corresponding side of the support frame 1 through a telescopic member 10 and a shielding film 3, and a universal wheel 2 is installed at the bottom of the support frame 1.

[0021] It should be noted that if Figure 2 , 3 The support frame 1 is an irregular polygon. A plurality of frames 4 are arranged between adjacent support frames 1, and adjacent frames 4 are connected by telescopic members 10 and shielding films 3. The frame 4 has the same structure as the support frame 1, but does not have a bottom edge, and only needs a top frame.

[0022] Preferably, if Figure 4 As shown, the telescopic member 10 includes: cross-arranged connecting rods 6, and the ends of the connecting rods 6 are hingedly mounted on the frame 4 or the support frame 1.

[0023] Specifically, the upper part of the connecting rod 6 is installed on the frame 4 or the support frame 1 through a rotatable connecting member 5, and the lower part of the connecting rod 6 is fixed to the slider 9 by a bolt 7. The slider 9 is installed on a slide rail 8 with a hole, and the slide rail 8 is installed on the frame 4 or the support frame 1. The slider 9 is moved on the slide rail 8 to perform telescopic movement. When it is necessary to adjust the opening and closing angle of the telescopic member 10, after lifting the bolt 7, the opening angle can be adjusted according to the lever principle. After determining the rear angle, the bolt 7 is pressed into the hole to complete the adjustment of the opening angle.

[0024] The shielding film 3 is installed between the support frame 1 and the frame 4 or between the frames 4. When the support frame 1 and the frame 4 are unfolded, the shielding film 3 is spread open.

[0025] Exemplarily, the number of the support frames 1 is three, and there are three wooden frames 4 between adjacent support frames 1 .

[0026] The working process of the utility model is:

[0027] Fix the universal wheel 2 on one side.
