[0029] It should be noted that a handle is provided at the upper end of the protective enclosure 3, and the flipping movement of the protective enclosure 3 is controlled by the handle. When unloading and loading, the protective enclosure 3 is arranged in parallel with the two ends of the low-bed semi-trailer, and will only flip when fencing.

[0030] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the adjustment mechanism 6 includes a support block 61 fixed to the side wall of the low-bed semi-trailer body 1, a rotating shaft 62 is rotatably connected in the middle of the support block 61, a handle 63 is sleeved on the outside of the rotating shaft 62, a connecting shaft 64 is inserted in the middle of the handle 63, a connecting frame 65 is sleeved on both ends of the connecting shaft 64, and a slot 66 is opened on both sides of the connecting frame 65, a slide plate 67 is slidably connected in the middle of the slot 66, a slide bar 68 is fixed on the top of the slide plate 67, and the slide bar 68 is fixedly connected to the hanging ring 5.

[0031] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a spring 69 is sleeved on the outside of the slide rod 68 , one end of the spring 69 is fixedly connected to the connecting frame 65 , and the other end of the spring 69 is fixedly sleeved on the slide rod 68 , and the slide rod 68 is slidably connected to the connecting frame 65 .

[0032] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, both ends of the slide plate 67 are provided with protrusions that slide horizontally with the empty groove 66.

[0033] It should be noted that protrusions are provided at both ends of the slide plate 67 and embedded in the slot 66 , so that the slide plate 67 can slide vertically through the slot 66 , and a margin for movement is provided for the slide plate 67 .

[0034] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the internal thread of the mounting plate 7 is connected to a screw rod 81, and the bottom of the mounting plate 7 is rotatably connected to a swivel ring 82, and the swivel ring 82 is threadedly matched with the screw rod 81, and a connecting ring 83 is installed at the bottom of the screw rod 81, and a fixing plate 84 is fixed to the bottom of the connecting ring 83, and connecting blocks 85 are fixed at both ends of the fixing plate 84, and a support shaft 87 is fixed to the bottom of the connecting block 85, and the outer part of the support shaft 87 is rotatably sleeved with a ring 88, and the ring 88 is fixedly sleeved with the support leg 8.

[0036] It should be noted that the threaded rod 86 is inserted through the connecting block 85 and embedded in the thread groove 89 of the collar 88 to clamp and limit it, thereby limiting the collar 88 to prevent it from rotating and thus affecting the stability of the support leg 8.

[0037] The use method and advantages of the utility model: When the low-bed semi-trailer with anti-falling function is working, the working process is as follows:

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the low-bed semi-trailer is installed and used with the front of the vehicle, and then the handle 63 is manually swung upward, and the handle 63 is immediately rotated around the rotating shaft 62, and at the same time, the connecting frame 65 installed by the connecting shaft 64 at the end of the handle 63 immediately slides up, and when sliding up, the two ends of the slide plate 67 slide along the empty grooves 66 at the two ends of the connecting frame 65, and when the slide plate 67 slides, it drives the slide bar 68 to slide in the connecting frame 65 and stretches the spring 69, so that the hanging ring 5 at the top of the slide bar 68 slides up immediately, so that it is in an inclined state with the hook 4, and then the handle 63 is pulled to drive the hanging ring 5 to slide outward and then detach from the hook 4, so that the limit is quickly released, and the handle is pulled to drive the protective enclosure 3 to flip, so that the protective enclosure 3 rotates to fit with the low-bed semi-trailer, so that the staff can load the goods;

[0039] After loading is completed, the protective panel 3 is turned over, and the protective panel 3 is rotated around the connecting rod 2 under force until the protective panel 3 and the low-bed semi-trailer are in a vertical fit state and stop rotating. Then, the handle 63 is manually opened to rotate around the rotating shaft 62. When the handle 63 rotates, the connecting frame 65 rotates immediately, and the hanging ring 5 is clamped into the hook 4. The handle 63 is manually turned, and the connecting frame 65 slides immediately. At the same time, the protrusions at both ends of the slide plate 67 slide along the empty grooves 66 on both sides of the connecting frame 65 and squeeze the spring 69 until the handle 63 is turned to a parallel fit state with the low-bed semi-trailer. The hanging ring 5 is firmly clamped with the hook 4, so that the protective panel 3 is firmly installed for easy use, so that it can enclose and protect the goods, avoid traffic accidents caused by the falling of goods during transportation, and improve the protective performance of use.

[0040] When transporting to the location for unloading, the semi-trailer is not parked stably due to the rugged ground during unloading, which makes it easy for workers to shake when unloading and unloading. Therefore, it needs to be supported. The swivel 82 is manually rotated. When the swivel 82 rotates, the screw 81 is forced to cooperate with its thread and then drive the bottom support leg 8 to slide down. After sliding to a suitable height, it stops rotating, so that it can be adjusted and supported for use on the ground of different heights. Then, the threaded rod 86 is rotated to pull out, and the manual rotating ring 88 drives the support leg 8 to rotate around the support shaft 87. After rotating to a suitable angle, the threaded rod 86 is rotated to embed into the threaded groove 89 to limit the position, so that it can be used for support on the ground with some slope, which is convenient for auxiliary support and placement of the semi-trailer, so that it is stable and does not shake during loading and unloading, thereby improving the stability of use.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
