The hanging beam of the present invention is mainly composed of a main beam and two folding beams. The two folding beams can be rotated to a folding position. At this time, the upper surfaces of the folding beams and the main beams fit together, reducing the overall length of the folding beams and the main beams to form a stacked form. The packaging size length will be greatly reduced during transportation, which greatly improves the convenience of transportation.

[0012] 2. The short beam can cooperate with the limiting protrusions on both sides of the main beam and the two folding beams through the spring locking pin on the guide arm.

By adjusting the telescopic state of the telescopic arms and selecting different hook mounting assemblies, the installation position of the hook can be conveniently adjusted, thereby adjusting the lifting position along the overall width direction of the beam.

[0014] 4. The present invention cooperates the positioning arc surface of the positioning block located at the end of the pin shaft with the arc groove of the main beam, so that the limiting teeth of the lifting seat and the limiting teeth of the main beam can be engaged with each other, so that the lifting seat can be locked relative to the main beam, or the locking of the lifting seat and the main beam can be released by simply rotating the pin shaft, so that the position of the lifting seat along the length direction of the main beam can be conveniently adjusted, thereby changing the center of gravity position of the entire lifting beam during lifting.

[0015] 5. The first hook mounting assembly and the second hook mounting assembly are both detachable. The short beam connecting ring is positioned by a bending pin, which can be bent conveniently. The position of the limit column on the telescopic arm connecting ring can be changed by operating the handle, so that the telescopic arm connecting ring can move on the telescopic arm, and the elastic force of the limit spring can reset the limit column and re-extend it into the limit column hole of the telescopic arm. It is not only easy to operate, but also the positioning structure is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 As shown, a lightweight universal packaging box hanging beam that is easy to transport includes a main beam 1 and two folding beams 2. The ends of the two folding beams 2 are connected to the two ends of the main beam 1 through a rotating shaft 3. The folding beams 2 can rotate between an extended position and a folded position. When in the extended position, the main beam 1 and the two folding beams 2 cooperate to form a long strip structure extending along the same length direction, as shown in FIG. Figure 1-5 As shown, the upper surfaces of the main beam 1 and the two folding beams 2 are detachably provided with short beams 4, and the middle part of the main beam 1 is detachably provided with a lifting assembly 9, which includes a lifting ring 13. When in the folded position, the two folding beams 2 are both located above the main beam 1, as shown in FIG. Figure 6 As shown, at this time, the ends of the two folding beams 2 are opposite to each other and the upper surfaces of the folding beams 2 and the main beam 1 are in contact with each other.

[0019] like Figure 1-4 As shown, the length direction of the short beam 4 extends along the width direction of the main beam 1 and the two folding beams 2, as shown in FIG. Figure 10 、 11 As shown, two guide arms 18 are provided on the lower surface of the short beam 4, and the two guide arms 18 extend downward to both sides of the main beam 1 or the folding beam 2 along the width direction. The two guide arms 18 are respectively provided with spring locking pins 19, which can extend to the opposite side of the two guide arms 18 through elastic force.

[0020] like Figure 5 、 6As shown in Figures 8 and 9, the main beam 1 and the two folding beams 2 are provided with a plurality of limiting protrusions 10 on their surfaces along the width direction. The plurality of limiting protrusions 10 on the same side are spaced apart along the length direction of the main beam 1 or the folding beam 2, and the limiting protrusions 10 on both sides are symmetrically distributed. The limiting protrusions 10 are provided with guide slopes and locking pin holes. When the two guide arms 18 of the short beam 4 move downward from the top to the two symmetrical limiting protrusions 10 on both sides of the main beam 1 or the folding beam 2, the ends of the two spring locking pins 19 can move along the guide slopes to the locking pin holes, so that the two spring locking pins 19 can be stretched by elastic force after being shortened and simultaneously stuck in the locking pin holes.

[0021] like Figure 1-4 As shown, two telescopic arms 6 are provided on the short beam 4. The length directions of the short beam 4 and the telescopic arms 6 are parallel to each other.

When the telescopic arm 6 is in the retracted position, the two bending pins 20 can respectively block the ends of the two telescopic arms 6. The telescopic arm 6 is provided with a plurality of bending pin holes 21 at intervals. When the telescopic arm 6 is in the extended position, the bending pins 20 can be inserted into the bending pin holes 21 to limit the extension length of the telescopic arm 6.

The bottom end of the lifting seat 12 extends below the limiting teeth 11 on both sides of the main beam 1. The bottom end of the lifting seat 12 is provided with two rows of upwardly protruding limiting teeth 11. The top of the lifting seat 12 is connected to the lifting ring 13 through a pin 14. The two ends of the pin 14 extend from the lifting ring 13 and are respectively installed with a positioning block 15.

Figure 9 As shown, when the positioning block 15 rotates with the pin shaft 14 until the positioning arc surface 16 is separated from the arc groove 17, the lifting seat 12 can move downward relative to the main beam 1 until the limit teeth 11 are separated from each other, so that the lifting seat 12 can move along the length direction of the main beam 1.

[0025] like Figure 13 As shown, the first hook mounting assembly 5 includes a short beam connecting ring 22, which is a semi-annular structure with an open top side.

The bottom end of the telescopic arm connecting ring 23 is used to install the hook, and a positioning bent plate 24 is connected above the top surface of the telescopic arm connecting ring 23. The positioning bent plate 24 is a semi-annular structure, and the two ends of the positioning bent plate 24 along the length direction are respectively connected to the top surface of the telescopic arm connecting ring 23. A pull plate 26 is provided between the lower surface of the positioning bent plate 24 and the top surface of the telescopic arm connecting ring 23, and the lower surface of the pull plate 26 is connected to two limit columns 27, as shown in FIG. Figure 12 As shown, a plurality of limiting column holes 30 are provided on the upper surface of the telescopic arm 6 at intervals along the length direction. The two limiting columns 27 both pass through the top surface of the telescopic arm connecting ring 23 and can extend into the two limiting column holes 30 respectively.

[0027] like Figure 14-15 As shown, the upper surface of the pull plate 26 is connected with a handle 25 and two guide columns 28. The top end of the guide column 28 is connected to the positioning bent plate 24. A limit spring 29 is provided on the guide column 28. The handle 25 can make the pull plate 26 move upward until the two limit columns 27 are disengaged from the limit column holes 30, so that the telescopic arm connecting ring 23 can move along the length direction of the telescopic arm 6. The elastic force of the limit spring 29 can make the pull plate 26 reset downward, so that the telescopic arm connecting ring 23 can be locked relative to the telescopic arm 6.

[0028] This embodiment adopts a universal non-elevation packaging box lifting beam, which is adapted to the lifting interfaces of various warehouse packaging box models, realizing universalization.
