The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.

As shown in fig. 1 to 4, the present invention provides a portable display device, which includes a display box, which is an aviation box with rollers for easy carrying and moving, and the display box can be used alone or in combination of a plurality of display boxes. Each display box includes: the device comprises a box body 1, a supporting assembly, a screen assembly 3, a winding assembly 4 and a pulley assembly 5. Screen subassembly 3 comprises articulated display element about the polylith, and collapsible accomodating is in the box when not using, also can expand and form the smooth display screen of a monoblock. The supporting component is accommodated in the box body, and the supporting frames 2 with different heights can be spliced according to needs during use. As shown in fig. 1 and 7, the supporting frame 2 can be directly mounted on the box body, or can be separated from the box body and directly and independently fixed, such as on the ground or on a mounting platform. When the screen needs to be used, the pulley assemblies 5 are installed at the top of the supporting frame, the winding assembly 4 is fixed on one side back to the screen assembly 3 and close to the bottom of the supporting frame, and the pull wire of the winding assembly 4 is connected with the screen assembly through the pulley assemblies at the top of the supporting frame. The winding assembly 4 can take the pulley assembly as a fulcrum to pull and expand the screen assembly upwards along the supporting frame to form a whole flat display screen.

The sheave assembly 5 includes: the pulley is installed in the installation seat and can rotate along the center shaft in the installation seat, the installation rod is fixed outside the installation seat and used for fixing the installation seat and the supporting frame, and installation hole positions are arranged on the supporting frame and can be used for installing the installation rod, so that the pulley assembly can be fixed on the supporting frame. The mounting seat can rotate relative to the mounting rod, so that different positions of the steel wire wound on the steel wire reel continuously are adapted.

The wire is a steel wire, and as shown in fig. 5 and 7, the winding member 4 includes: a wire 41, a wire drum 42 and a motor 43 for driving the wire drum to rotate.

Both ends of the vertical rod can be spliced with the vertical connecting pipe. And the vertical rods can be inserted into the two ends of the vertical connecting pipe, and meanwhile, the vertical base on the base can be inserted into the vertical connecting pipe, so that the connecting joint is fixed on the vertical base. Wherein the lower end of a vertical rod of a connecting knot used at the top of the support frame is inserted with the vertical pipe, and the upper end is closed.

In this embodiment, the support assembly may constitute a single sided support frame.

In another embodiment, as shown in fig. 8, the support assembly comprises: base 21, tie knot 22, first horizontal pole 23, second horizontal pole 25 and montant 24, base 21 are platelike, and the interval is equipped with two vertical bases on the holding surface of base 21, and the vertical takeover 221 of a tie knot 22 can be connected to every vertical base, forms the base support through two fixed tie knots, and the base support can be fixed on the box, also can fix alone, for example the snap-on is on ground or other mounting platform.

The connection knot includes: a vertical joint pipe 221, a first lateral joint pipe 222 and a second lateral joint pipe 223, the first lateral joint pipe 222 and the second lateral joint pipe 223 being vertically connected to the side of the vertical joint pipe 221, and the first lateral joint pipe 222 and the second lateral joint pipe 223 being vertically connected. Both ends of the first cross bar 23 may be inserted into the first lateral connection tubes 222, and both ends of the second cross bar 25 may be inserted into the second lateral connection tubes 223.
