[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-3 As shown, the utility model provides a technical solution: a manual transport cart with height adjustment, comprising: a cart mechanism 1, the cart mechanism 1 comprises a push handle 11, one end of the push handle 11 is provided with a moving frame 12, one end of the push handle 11 is fixedly connected to one end of the moving frame 12 by welding, a limit frame 13 is provided on the moving frame 12, the bottom of the limit frame 13 is fixedly connected to the moving frame 12 by welding, a lifting mechanism 2 is provided in the limit frame 13, the lifting mechanism 2 comprises a sliding bottom frame 21, the outer surface of the sliding bottom frame 21 is fixedly connected to the limiting frame 13 by welding, an adjusting frame 22 is provided in the sliding bottom frame 21, and the two ends of the adjusting frame 22 are respectively butted On the sliding bottom frame 21 and the top plate 27, both ends of the connecting rod 23 are docked on the adjusting frame 22, the connecting rod 23 is provided at the connection of the adjusting frame 22, a hydraulic cylinder 24 is provided on the connecting rod 23, one end of the hydraulic cylinder 24 is fixedly connected to the connecting rod 23 by welding, a docking frame 25 is provided at one end of the hydraulic cylinder 24, both ends of the docking frame 25 are docked on the adjusting frame 22, one end of the hydraulic cylinder 24 away from the connecting rod 23 is fixedly connected to the docking frame 25 by welding, a hydraulic handle 26 is provided on the hydraulic cylinder 24, one end of the hydraulic handle 26 is docked between the two hydraulic cylinders 24, and a top plate 27 is provided at one end of the adjusting frame 22 away from the sliding bottom frame 21.

[0027] In this embodiment, when the staff uses the manual cart to transport objects, they can place the objects on the top plate 27, and then move the movable frame 12 by pushing and pulling the push handle 11. When the cart moves to the position where the transport is completed, it stops moving. After that, the staff only needs to press the hydraulic handle 26 back and forth to squeeze the hydraulic cylinder 24 outward, so that the two ends of the hydraulic cylinder 24 are squeezed and lifted between the connecting rod 23 and the docking frame 25 respectively, so that the object can be raised to a higher height. When the height of the object rises to the height that the staff needs to transport, the pressing of the hydraulic handle 26 can be stopped. In this way, the objects that need to be transported can be more conveniently brought to the same height as the transfer platform, making it more convenient for the staff to work, thereby improving its practicality in actual use.

[0028] Example 2

[0029] like Figure 1-4 As shown, auxiliary mechanisms 3 are provided on both sides of the top plate 27 and the sliding bottom frame 21, and the auxiliary mechanism 3 includes a sliding frame 31, a sliding track 32 is provided in the sliding frame 31, and an embedded sliding plate 33 is provided on the outer surface of the sliding track 32, one side of the sliding frame 31 is fixedly connected to one side of the sliding bottom frame 21 by welding, one side of the sliding track 32 is fixed in the sliding frame 31 by welding, the inner side of the embedded sliding plate 33 is connected to the outer surface of the sliding track 32 by nesting to perform sliding adjustment, and one side of the embedded sliding plate 33 is fixedly connected to one side of the top plate 27 by welding.

[0030] In this embodiment, in order to further improve its practicality in actual use, an auxiliary mechanism 3 is used to perform lifting and lowering auxiliary balance between the sliding bottom frame 21 and the top plate 27. When the top plate 27 rises under the action of the hydraulic cylinder 24, the embedded sliding plate 33 will slide and lift on the outer surface of the sliding track 32 for adjustment. This will prevent the top plate 27 from shaking during the lifting process, thereby further improving its practicality in actual use.

[0031] Working principle:

[0032] like Figure 1-4 As shown, when the staff uses the manual cart to transport objects, they first place the objects on the top plate 27. Then, by pushing and pulling the push handle 11 to operate the moving frame 12, the cart is pushed to the destination and then stops moving. Then, the staff only needs to press the hydraulic handle 26 to squeeze the hydraulic cylinder 24 outward, so that the two ends of the hydraulic cylinder 24 between the connecting rod 23 and the docking frame 25 are squeezed and raised respectively, so that the object is raised to the desired height. Once the object reaches the desired height, stop pressing the hydraulic handle 26. This design makes it easier for the transported object to be aligned with the transfer platform, which is convenient for the staff to operate.

[0033] In order to further improve the convenience of use, an auxiliary mechanism 3 is designed to assist in lifting and balancing. When the top plate 27 rises under the action of the hydraulic cylinder 24, the embedded sliding plate 33 will slide and rise and fall on the outer surface of the sliding track 32 to prevent the top plate 27 from shaking during the lifting process. This design further improves the practicality of the top plate 27 in actual use.
