It includes a handling frame and an auxiliary mechanism. The auxiliary mechanisms are symmetrically distributed on both sides of the handling frame. The auxiliary mechanism includes a moving frame, a threaded rod, a rotating block and a limiting rod. A connecting ring is arranged below the rotating block. A connecting shaft penetrates between the rotating block and the connecting ring. The connecting ring is rotatably connected to the rotating block, and the connecting ring is fixedly connected to the side wall of the handling frame; a threaded rod is rotatably installed on the side of the rotating block away from the connection with the handling frame, and a sliding rod is fixedly installed.

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0031] In this embodiment, it is disclosed that when the connecting screw rod 12 rotates, it will drive the two bearing bottom plates 2 to move, and adjust the distance between the two bearing bottom plates 2. Specifically, as shown in Figure 1 and Figures 3 - 4 shown:

[0032] A fixing plate 3 is installed on the side of the mounting plate 1, a hydraulic rod 4 is installed on the fixing plate 3, and a support pull rod 5 is also installed on the fixing plate 3. A pull ring 6 is installed at the top of the support pull rod 5;

[0033] The connecting screw rod 12 is also connected to the mounting plate 1 by a bearing. The outer wall of the connecting screw rod 12 is connected to the bearing bottom plate 2. A knob 13 is installed at the front end of the connecting screw rod 12. The thread directions of the front and rear ends of the connecting screw rod 12 are opposite, and the connecting screw rod 12 is threadedly connected to the bearing bottom plate 2. A limiting block 14 is provided between the knob 13 and the mounting plate 1, and the limiting block 14 is snap-fitted to the connecting screw rod 12, and the limiting block 14 is made of rubber material;

[0034] When using this manual hydraulic hand truck for preventing goods from falling, first place the hand truck in the corresponding position. There are two bearing bottom plates 2 arranged below the mounting plate 1, and casters are installed at the bottoms of both the mounting plate 1 and the bearing bottom plates 2. Therefore, the mounting plate 1 and the bearing bottom plates 2 can be moved through the casters. When it is necessary to tow goods, the distance between the two bearing bottom plates 2 can be adjusted according to the size of the goods first. For example, when the width of the goods is smaller than the distance between the two bearing bottom plates 2, the limit block 14 can be removed from the connecting lead screw 12 first, and then the knob 13 is rotated clockwise. The knob 13 will drive the connecting lead screw 12 to rotate together. Since the connecting lead screw 12 and the bearing bottom plate 2 are in threaded connection, and the thread directions at the front and rear ends of the connecting lead screw 12 are opposite, when the connecting lead screw 12 rotates, it will drive the two bearing bottom plates 2 to move closer to each other, shortening the distance between the two bearing bottom plates 2. Embodiment Two:

[0035] In this embodiment, it is disclosed that under the action of the connecting block 15, the bearing bottom plate 2 can move more smoothly, effectively preventing the phenomenon of shaking when the bearing bottom plate 2 moves. Specifically, as Figure 6 shown:

[0036] The upper surface of the bearing bottom plate 2 is provided with a connecting block 15, and the connecting block 15 and the mounting plate 1 are in sliding connection, and the connecting ends of the connecting block 15 and the mounting plate 1 are in a "T" shape;

[0037] When the bearing bottom plate 2 moves, since the upper surface of the bearing bottom plate 2 is provided with a connecting block 15, and the connecting block 15 and the mounting plate 1 are in sliding connection, under the action of the connecting block 15, the bearing bottom plate 2 can move more smoothly, effectively preventing the phenomenon of shaking when the bearing bottom plate 2 moves. When the distance between the two bearing bottom plates 2 is adjusted appropriately, the rotation of the knob 13 can be stopped, and the limit block 14 is snapped and nested on the connecting lead screw 12. Since the limit block 14 is made of rubber and the limit block 14 is in contact with both the mounting plate 1 and the knob 13, the connecting lead screw 12 can be limited by the limit block 14, preventing the phenomenon of accidental contact with the knob 13 and causing rotation during the goods handling process. Furthermore, the two bearing bottom plates 2 can be more stable after the position is adjusted. Embodiment Three:

[0038] In this embodiment, it is disclosed that under the action of the protection plate 9, the goods can be protected, effectively preventing the phenomenon of falling when the goods are handled and moved. Specifically, as Figure 2 , Figure 5 and Figure 7 shown:

[0039] A first connecting rod 7 and a second connecting rod 8 are arranged between the load-bearing bottom plates 2, and a protective structure capable of preventing goods from falling is arranged on the outer side of the load-bearing bottom plates 2, and the protective structure includes a protective plate 9;

[0040] The first connecting rod 7 and the second connecting rod 8 are slidably connected, the inner diameter of the first connecting rod 7 is greater than the outer diameter of the second connecting rod 8, and the second connecting rod 8 and the surface of the load-bearing bottom plate 2 are welded. The first connecting rod 7 and the second connecting rod 8 are equally spaced between adjacent load-bearing bottom plates 2. Fixing holes 10 are formed in the protective plate 9, and there are two protective plates 9;

[0041] Docking blocks 11 are fixed on the side walls of the load-bearing bottom plates 2, and the docking blocks 11 are equally spaced, and the sizes of the docking blocks 11 match the sizes of the fixing holes 10;

[0042] Then, the goods are placed on the two load-bearing bottom plates 2. Since the docking blocks 11 are installed on the outer sides of the load-bearing bottom plates 2 and the sizes of the docking blocks 11 match the sizes of the fixing holes 10 on the protective plate 9, the protective plate 9 and the docking blocks 11 can be docked and installed to ensure that the protective plate 9 is stable and firm. Under the action of the protective plate 9, the goods can be protected, effectively preventing the goods from falling when being transported and moved. Moreover, equally spaced first connecting rods 7 and second connecting rods 8 are arranged between adjacent load-bearing bottom plates 2, and the first connecting rod 7 and the second connecting rod 8 are slidably connected. Therefore, when the distance between the two load-bearing bottom plates 2 is adjusted, the first connecting rod 7 and the second connecting rod 8 will slide and adjust automatically. And when placing the goods, the goods can be further supported by the first connecting rod 7 and the second connecting rod 8 to better place the goods. Then, the staff can pull the pull ring 6 to pull the support rod 5, and drive the mounting plate 1 and the load-bearing bottom plate 2 to move together through the support rod 5 to achieve the purpose of transporting the goods. The above is the working process of the entire device. The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
