The upper end of the column 3 is connected to the upper hanging head 4 through a locking mechanism 6, so that the top beam 1 and the column 3 are fixed and cannot move relative to each other. The lower end of the column 3 is connected to the lower hanging head 5 through a locking mechanism 6, so that the bottom beam 2 and the column 3 are fixed and cannot move relative to each other. When in the folded state, the column 3 is horizontal between the top beam 1 and the bottom beam 2, and the top beam 1 is placed on the lower hanging head 5 on the bottom beam 2 through the upper hanging head 4, that is, the lower hanging head 5 supports the upper hanging head 4, thereby supporting the entire top beam 1; when in the unfolded state, the column 3 is in a vertical state, and two locking mechanisms 6 respectively lock the upper and lower ends of the column 3 with the upper hanging head 4 and the lower hanging head 5 to ensure that it can be stably in the unfolded state. It should be known that the top beam 1 has a drainage channel 12, which is used for drainage.

[0030] Combination Figure 6 and Figure 7 For reference, the top beam 1 has a track 11, and a hinge 31 is provided at the upper end of the column 3. A pulley 32 is provided on the hinge 31. The pulley 32 slides in the track 11, and the track 11 extends into the upper hanging head 4. A mounting plate 33 is provided at the lower end of the column 3. A positioning pin 34 is provided on the mounting plate 33. The positioning pin 34 is inserted on the lower hanging head 5, and the positioning pin 34 can slide on the lower hanging head 5. The upper and lower ends of the column 3 are both provided with external locking holes 35 that cooperate with the locking mechanism 6, and the mounting plate 33 is provided with a perforation 36 corresponding to the external locking hole 35. An intermediate downpipe 37 is provided in the column 3, and the intermediate downpipe 37 is used as an intermediate drainage channel. The intermediate downpipe 37 is connected to the upper hanging head 4, and the lower end of the intermediate downpipe 37 is connected to the external drainage channel or directly discharged into the ground. A drainage pipe is separately provided in the column 3, which can effectively prevent rainwater from corroding the inner cavity of the column 3. The middle downpipe 37 is usually made of plastic, which is cost-saving and easy to install.

[0031] like Figure 8 and Fig. 9As shown, the upper hanging head 4 includes a first hanging head body 41, a first connecting plate 42, an upper downpipe 43, a first sealing plate 44 and a first reinforcing plate 45. The first hanging head body 41 is provided with a water inlet 411, an avoidance gap 412 and a hanging hole 413, and the hanging hole 413 is used to lift the hanging head 4 by a crane. The first sealing plate 44 is installed in the first hanging head body 41 to form a water collecting chamber 402 and a receiving chamber 401, and the water collecting chamber 402 is connected with the water inlet 411, so that the drainage channel 12 is connected with the water collecting chamber 402, and the rainwater of the top beam 1 can be introduced into the water collecting chamber 402. The receiving chamber 401 and the water collecting chamber 402 are independent and not connected, so that it can be ensured that the rainwater in the water collecting chamber 402 will not enter the receiving chamber 401, and the track 11 extends into the receiving chamber 401, and the receiving chamber 401 is used to accommodate the pulley 32. The upper downpipe 43 is installed on the first sealing plate 44 . The upper downpipe 43 is communicated with the first water inlet cavity. Rainwater in the water collecting cavity 402 can be discharged from the first hanging head body 41 through the upper downpipe 43 . The avoidance gap 412 is used to avoid the hinge 31, so that the hinge 31 will not interfere with the first hanging head body 41 when sliding on the slide; the hinge 31 is provided with a protrusion 311, the width of the protrusion 311 is greater than the width of the avoidance opening 532, and the width of the hinge 31 is less than the width of the avoidance opening 532, so that when the hinge 31 slides on the slide, it can slide freely, and when it is unfolded, that is, when the column 3 and the upper hanging head 4 are locked by the locking mechanism 6, the protrusion 311 cannot be moved out of the first hanging head body 41, protecting the pulley 32 from being eroded by rainwater; and before the column 3 and the upper hanging head 4 are aligned, the position of the protrusion 311 is lower than the avoidance gap 412, so that the pulley 32 can slide smoothly before alignment. The water inlet 411 is arranged corresponding to the drainage channel 12 of the top beam 1, that is, the drainage channel 12 of the top beam 1 is connected to the water inlet 411. The water collecting chamber 402 and the upper downpipe 43 form a drainage channel, the middle downpipe 37 is connected to the upper downpipe 43, and rainwater enters the middle downpipe 37. The first connecting plate 42 is installed on the first hanging head body 41, and the first connecting plate 42 is used to connect with the column 3; the first connecting plate 42 is provided with a first locking hole 421 for installing the locking mechanism 6. The first reinforcing plate 45 is installed on the first hanging head body 41, and the first reinforcing plate 45 is installed horizontally, and the first reinforcing plate 45 is used to increase the strength of the first hanging head body 41. The first reinforcing plate 45 is provided with a through hole 36 for the upper downpipe 43 to pass through, and the diameter of the through hole 36 is larger than the diameter of the upper downpipe 43, so that the middle downpipe 37 can be sleeved on the upper downpipe 43.

[0032] like Fig.10 and Fig.11As shown, the lower hanging head 5 includes a second hanging head body 51, a second connecting plate 52 and a second reinforcing plate 53, the second connecting plate 52 is installed on the second hanging head body 51, the second connecting plate 52 is used to be connected to the lower end of the column 3, the second reinforcing plate 53 is installed on the second hanging head body 51, and the second reinforcing plate 53 is connected to the second connecting plate 52, so as to increase the strength of the second hanging head body 51 and the second connecting plate 52; the second reinforcing plate 53 is provided with a drainage hole 531, the lower end of the middle downpipe 37 is located in the drainage hole 531, and the drainage hole 531 is used to stabilize the middle downpipe 37 to prevent the middle downpipe 37 from shaking; the second reinforcing plate 53 is provided with an avoidance opening 532 for avoiding the positioning pin 34. A guide groove 521 is provided on the second connecting plate 52, and the positioning pin 34 is located in the guide groove 521. The lower end of the guide groove 521 is vertically arranged, and the upper end of the guide groove 521 is inclined. The inclined section of the guide groove 521 is provided with a positioning groove 522, and the positioning groove 522 is located below the guide groove 521 and is connected to the guide groove 521, so that the positioning pin 34 can stably rotate in the positioning groove 522. When folding, the positioning pin 34 is inserted into the guide groove 521. When unfolding is required, the lower end of the column 3 rotates in the positioning groove 522 with the positioning pin 34 as the support point. When the column 3 rotates to the vertical state, the positioning pin 34 enters the guide groove 521 from the positioning groove 522. Then, during the process of lowering the column 3, the lower end of the column 3 is manually pulled to allow the positioning pin 34 to move along the guide groove 521, so that the column 3 can be quickly aligned with the lower hanging head 5, without repeatedly adjusting the position of the column 3 to align with the lower hanging head 5. After alignment, the locking mechanism 6 can be used to lock the column 3 and keep the column 3 and the lower hanging head 5 in the unfolded state. The positioning groove 522 is higher than the second hanging head body 51, which can ensure that there is enough space when the column 3 rotates. At the same time, the lower hanging head 5 and the column 3 are movably connected by the positioning pin 34, so that the lower hanging head 5 can be completely matched with the column 3, so that there will be no exposed structure at the connection position to prevent rainwater from entering. The second connecting plate 52 is provided with a second locking hole 523 for installing the locking mechanism 6 .

[0033] The locking mechanism 6 is a bolt and a nut, and the nut is welded and fixed to the corresponding first connecting plate 42 or the second connecting plate 52; the bolt passes through the outer locking hole 35 on the column 3 and the through hole 36 on the mounting plate 33, and is screwed with the nut on the corresponding second connecting plate 52, or the bolt passes through the outer locking hole 35 on the column 3 and is screwed with the nut on the corresponding first connecting plate 42, so as to realize the connection between the locking column 3 and the upper hanging head 4 and the lower hanging head 5.

[0034] When it is necessary to unfold, the hook of the crane is hooked in the hanging hole 413, and then the top beam 1 is raised by the crane. After the column 3 is tilted, the middle downpipe 37 is sleeved and fixed with the upper downpipe 43, and then the top beam 1 is continued to be raised until the pulley 32 slides into the accommodating chamber 401, and then the top beam 1 is lowered and the lower end of the column 3 is guided to move along the guide groove 521 until the column 3 is aligned with the lower hanging head 5, and the column 3 is also synchronously aligned with the upper hanging head 4. Due to the effect of the positioning pin 34, the column 3 can be automatically aligned with the lower hanging head 5, and then the bolts are tightened to lock the upper hanging head 4 and the lower hanging head 5 with the column 3. When it is necessary to fold, the reverse operation can be performed. The operation is simple and convenient, and the drainage channel is hidden in the column 3 and the upper hanging head 4 to avoid wind and sun, prolong the service life of the middle downpipe 37, and make the packing box look neater and more beautiful.
