[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In addition, the up, down, left, right, front, and back mentioned in the embodiments of the invention refer to the wheelbarrow of the present invention when it is placed vertically on the ground (see the attached figure). Figure 1 The positive direction of X represents "right", the negative direction of X represents "left", the positive direction of Y represents "front", the negative direction of Y represents "back", the positive direction of Z represents "up", and the negative direction of Z represents "down".

[0033] See also Figure 1-3 As shown, an embodiment of the present invention provides a trolley, comprising a body 1 for carrying goods, at least two baffle assemblies are arranged on the body 1, and each baffle assembly defines a receiving space of different sizes.

[0034] The trolley provided in this embodiment is provided with two or more baffle assemblies on the body 1, and each baffle assembly is suitable for defining a storage space, and the storage space is used to place goods. This embodiment is preferably used to place a liquid nitrogen tank 4, and of course other objects with regular or irregular shapes can also be placed. When using the trolley, select a suitable baffle assembly according to the size of the goods being pushed. In this way, one trolley can be used to transport goods of different sizes, avoiding multiple transport vehicles occupying space, saving resources, and realizing the maximum utilization of the trolley. In addition, the size of the body 1 matches the size of the goods, avoiding a large vehicle pulling small goods, causing a waste of resources, and at the same time, the goods can be better fixed, and the goods are not easy to fall off or become unstable when the trolley moves.

[0035] The baffle assembly includes a first baffle assembly suitable for being received in the vehicle body 1, the first baffle assembly includes at least three baffles 11, and the at least three baffles 11 enclose a storage space suitable for storing goods. It should be understood that different first baffle assemblies can share the baffle 11, for example, two first baffle assemblies are provided on the vehicle body 1, one of the first baffle assemblies includes a baffle 11A, a baffle 11B and a baffle 11C, and the other first baffle assembly includes a baffle 11A, a baffle 11B and a baffle 11C'.

[0036] A groove 13 is provided on the upper surface of the vehicle body 1, and the baffle 11 is suitable for being received in the groove 13. The baffle 11 can rotate relative to the upper surface of the vehicle body 1, and the rotation angle is 0-90°. When the rotation angle is 0, the baffle 11 is received in the groove 13, and the upper surface of the baffle 11 is flush with the upper surface of the vehicle body 1; when the rotation angle is 90°, the baffle 11 is perpendicular to the upper surface of the vehicle body 1. At this time, three or more baffles 11 enclose a storage space on the vehicle body 1, which is suitable for limiting the movement of goods. There is no specific restriction on the rotational connection between the baffle 11 and the vehicle body 1, such as connecting the baffle 11 and the vehicle body 1 by hinges.

[0037] The first baffle assembly further includes a support member 14, which is suitable for fixing the flipped baffle 11, that is, supporting the baffle 11 when the baffle 11 is perpendicular to the upper surface of the vehicle body 1. Figure 4-6 As shown, when the baffle 11 is flipped upward, the support member 14 moves toward the side wall of the groove 13 and abuts against the side wall of the groove 13, thereby fixing the baffle 11. The fixation of the baffle 11 can fix the goods loaded on the vehicle body 1, such as the liquid nitrogen tank 4; when the liquid nitrogen tank 4 needs to be removed, the support member 14 is stored in the groove 13, and the baffle 11 is flipped downward and stored in the groove 13.

[0038] The support member 14 can be an independent component or a component fixed to the baffle 11. In this embodiment, the support member 14 is preferably arranged on the baffle 11, so that the support member 14 is easy to store and prevent the loss of the component. One end of the support member 14 is connected to the lower surface of the baffle 11, and the other end of the support member 14 is suitable for abutting against the side wall of the groove 13, so as to support the erected baffle 11. Preferably, a concave hole suitable for the other end of the support member 14 to abut is provided on the side wall of the groove 13. The provision of the concave hole can improve the stability of the support member 14.

[0039] In one embodiment, the support member 14 is a telescopic rod. When the baffle 11 needs to be erected, the baffle 11 is lifted from the groove 13 until the baffle 11 is perpendicular to the upper surface of the vehicle body 1, and the telescopic rod is extended. One end of the telescopic rod is fixed on the baffle 11, and the other end of the telescopic rod is in contact with the side wall of the groove 13, so that the baffle 11 is erected. When the baffle 11 needs to be lowered, the telescopic rod is retracted, and the retracted rod and the baffle 11 are stored in the groove 13 together. Furthermore, in order to keep the upper surface of the vehicle body 1 flat, a receiving groove suitable for accommodating the telescopic rod is provided on the lower surface of the baffle 11. When the retracted rod and the baffle 11 are stored in the groove 13 together, the retracted rod is located in the receiving groove, so that the lower surface of the baffle 11 is close to the bottom wall of the groove 13.

[0040] In another embodiment, the support member 14 is a fixed support rod, one end of which is hinged to the lower surface of the baffle 11. When the baffle 11 needs to be erected, the baffle 11 is rotated around the axis connected to the vehicle body 1 until the baffle 11 is perpendicular to the upper surface of the vehicle body 1, and the fixed support rod is abutted against the concave hole; when the baffle 11 needs to be lowered, since one end of the fixed support rod is hinged to the baffle 11, one end of the fixed support rod can be rotated so that the other end of the fixed support rod can be placed in the groove 13.

[0041] The present invention provides a specific implementation method, wherein the first baffle assembly includes a first baffle 111, a second baffle 112, a third baffle 113 and a fourth baffle 114 respectively arranged on the front, rear, left and right sides of the upper surface of the vehicle body 1, so that when loading goods on the vehicle body 1, the goods can be fixed from four directions, and the number of baffles 11 is reduced on the basis of ensuring the cargo fixing effect, thereby simplifying the structure. The first baffle assembly also includes a first groove 13, a second groove 13, a third groove 13 and a fourth groove 13 respectively arranged on the front, rear, left and right sides of the upper surface of the vehicle body 1, and the first baffle 111, the second baffle 112, the third baffle 113 and the fourth baffle 114 are respectively rotatably connected to the vehicle body 1, and the first baffle 111 is suitable for being received in the first groove 13, the second baffle 112 is suitable for being received in the second groove 13, the third baffle 113 is suitable for being received in the third groove 13, and the fourth baffle 114 is suitable for being received in the fourth groove 13. The first baffle assembly further includes a first support member 14 , a second support member 14 , a third support member 14 and a fourth support member 14 which are respectively disposed in the first groove 13 , the second groove 13 , the third groove 13 and the fourth groove 13 .

[0042] like Figure 1As shown, the baffle assembly also includes a second baffle assembly fixedly mounted on the vehicle body 1, and the second baffle assembly includes a fixed baffle 12 mounted on the edge of the vehicle body 1, and the number of the fixed baffles 12 is at least three. Preferably, the fixed baffles 12 include a first fixed baffle 12, a second fixed baffle 12, a third fixed baffle 12 and a fourth fixed baffle 12 respectively arranged at the four corners of the edge of the vehicle body 1. The fixed baffles 12 are arranged around the edge of the vehicle body 1, so that a storage space suitable for placing larger-sized goods can be defined.

[0043] Preferably, a second baffle assembly and at least one first baffle assembly are provided on the vehicle body 1, so that the maximum size of the goods carried by the trolley is limited according to the second baffle assembly, and the first baffle assembly is adjusted to accommodate other goods smaller than the maximum size.

[0044] Furthermore, the trolley also includes a pedal 2, which is rotatably connected to the vehicle body 1. The pedal 2 is used to assist manpower in moving goods from the ground to the vehicle body 1. The end of the pedal 2 away from the vehicle body 1 can be rotated to contact the ground. Since the vehicle body 1 is generally provided with casters at the bottom, when the end of the pedal 2 away from the vehicle body 1 contacts the ground, the pedal 2 is placed at an angle, so that it is convenient for the goods placed on the ground to be moved onto the pedal 2, and then further moved onto the vehicle body 1. After the goods are transported to the vehicle body 1, the pedal 2 is retracted from the ground and rotated to form a first angle with the vehicle body 1. The first angle is an obtuse angle or 90°, preferably 90°, that is, the pedal 2 is perpendicular to the vehicle body 1. In this way, the pedal 2 also serves as a handle, and the vehicle body 1 can be moved by pushing the pedal 2. There are many ways to achieve the rotational connection between the pedal 2 and the vehicle body 1 and to fix the pedal 2 when the pedal 2 is rotated to be perpendicular to the vehicle body 1, such as Figure 7 As shown, for example, the pedal 2 is connected to the vehicle body 1 by a hinge, and a first hinge and a second hinge are provided on the rotating shaft of the hinge, the first hinge is connected to the vehicle body 1, and the second hinge is connected to the pedal 2. When the pedal 2 rotates upward and forward from contact with the ground to an angle perpendicular to the ground, a stopper is provided on the vehicle body 1 to prevent the pedal 2 from moving further forward. At this time, pushing the pedal 2 can push the entire cart.

[0045] Since the liquid nitrogen tank 4 is heavy, it takes manpower to carry it. A heavy liquid nitrogen tank 4 generally requires two people to operate. In this embodiment, a pedal 2 is provided on the vehicle body 1, and the pedal 2 can be rotated to contact the ground, so that when the liquid nitrogen tank 4 is carried to the trolley, the pedal 2 plays a role of transferring. When in use, the pedal 2 is first rotated until one end thereof contacts the ground, the liquid nitrogen tank 4 is pushed onto the pedal 2, and then the liquid nitrogen tank 4 is further moved onto the vehicle body 1, so as to avoid multiple people lifting the liquid nitrogen tank 4 onto the vehicle body 1, which is time-consuming and laborious.

[0046] Preferably, in order to facilitate the movement of the liquid nitrogen tank 4 on the pedal 2, as Figure 1 , 3As shown, a plurality of rollers 21 are installed in the pedal 2, and one installation method of the rollers 21 is that a mounting groove for mounting the rollers 21 is provided in the pedal 2, and both ends of the rollers 21 are fixed to the two side walls of the mounting groove, and a gap suitable for the rotation of the rollers 21 is left between the rollers 21 and the bottom wall of the mounting groove. In this embodiment, the provision of the rollers 21 helps to reduce the friction when the liquid nitrogen tank 4 moves, so that the heavy liquid nitrogen tank 4 can be moved to the vehicle body 1 more conveniently.

[0047] Furthermore, the trolley also includes a handle 3 for pushing the vehicle body 1, and the handle 3 is connected to the pedal 2. One end of the pedal 2 is rotatably connected to the vehicle body 1, and the other end of the pedal 2 is connected to the handle 3. Since the pedal 2 is mainly used to facilitate loading of goods onto the vehicle body 1, the height of the pedal 2 should not be too high. The so-called height of the pedal 2 refers to the size of the pedal 2 in the up and down direction when the pedal 2 is perpendicular to the vehicle body 1. Therefore, the present embodiment provides a handle 3 to facilitate pushing the trolley. Preferably, the handle 3 is a retractable handle 3, and the handle 3 is pulled out when in use, and the handle 3 is retracted into the pedal 2 when not in use. In this way, it is convenient for people of different heights to use the trolley.

[0048] It should be understood that casters are provided at the bottom of the vehicle body 1, and a locking structure for locking the casters is provided at the bottom of the vehicle body 1. These are prior arts and will not be described here in detail.

[0049] The use process of the trolley in this embodiment is as follows: Take the transportation of liquid nitrogen tank 4 as an example. Figure 8-10 As shown, when the liquid nitrogen tank 4 needs to be transported, the baffle assembly on the vehicle body 1 is selected according to the size of the liquid nitrogen tank 4. If the diameter of the liquid nitrogen tank 4 is large, the second baffle assembly is used to fix the liquid nitrogen tank 4. At this time, each baffle 11 of the first baffle assembly is retracted into each corresponding groove 13. If the diameter of the liquid nitrogen tank 4 is small, the first baffle assembly is used to fix the liquid nitrogen tank 4. At this time, each baffle 11 of the first baffle 111 is flipped out from each corresponding groove 13. Rotate the pedal 2 until one end of it contacts the ground, and lock the caster through the locking structure to fix the trolley. Move the liquid nitrogen tank 4 to the pedal 2, and then move it from the pedal 2 to the vehicle body 1, and fix the liquid nitrogen tank 4 through the baffle assembly. Rotate the pedal 2 to an angle perpendicular to the ground, fix the pedal 2, and pull out the handle 3 from the pedal 2 to push the trolley.

[0050] The trolley provided by the present invention can transport goods of different sizes, and is convenient for carrying goods onto the trolley. Compared with the prior art, on the one hand, it avoids that one trolley can only transport goods of one size, and when goods of multiple sizes need to be carried, the number of trolleys is increased, space is occupied, and resources are wasted. On the other hand, it avoids that multiple people carry goods onto the vehicle body 1, which is time-consuming and laborious.

[0051] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
