In this embodiment, the connecting plate 9 is provided with a receiving groove 18 engaged with the hinge rod 16, so that the hinge rod 16 at the lower end of the second bottom plate 15 can rotate in the receiving groove 18. One end of each of the 2 telescopic rods 6 close to the limiting plate 7 is provided with a second limiting groove 19, a limiting column 20 is arranged in each second limiting groove 19, each limiting column 20 is provided with a sliding seat 21 in sliding fit with the corresponding sliding seat, and a limiting rod 22 is welded among the 2 sliding seats 21; a compression spring 23 is sleeved on each limiting column 20, and the compression spring 23 supports the sliding base 21 against one end of the second limiting groove 19 close to the limiting plate 7. The upper surface of the fixed seat 11 and one side close to the first bottom plate 1 are respectively provided with a clamping groove 24; the vertical rods on the two sides of the n-shaped handrail 12 are respectively hinged with the fixed seats 11 at the corresponding positions; a third limiting groove 26 is formed in the outer side of each vertical rod on two sides of the n-shaped handrail 12, a T-shaped sliding block 27 in sliding fit with the third limiting groove 26 is arranged in the third limiting groove 26, and one end, located outside the third limiting groove 26, of the sliding block 27 corresponds to the clamping groove 24 in position; the lower surface of one end of the sliding block 27, which is positioned outside the third limiting groove 26, is provided with a magnet 25, and the magnet and the clamping groove 24 are mutually attracted, so that one end of the sliding block 27, which is positioned outside the third limiting groove 26, is fixed in the clamping groove 24; the upper surface of the sliding block 27 is provided with a pull ring 28, which is convenient for taking the sliding block 27 out of the clamping groove 24 and sliding in the third limiting groove 26. The front end of the first base plate 1 is provided with a third base plate 29, and the third base plate 29 is hinged to the first base plate 1 through a hydraulic hinge 30. A handle 31 is welded at one end of the connecting plate 9 far away from the telescopic rod 6, so that the folded trolley is convenient to carry.

The working principle is as follows: when the portable trolley is used, goods are stacked on the first bottom plate 1, then the third bottom plate 29 is rotated, so that the horizontal placement of the third bottom plate 29 is changed into vertical placement under the action of the hydraulic hinges 30, and the goods can be prevented from being inclined forwards and being separated from the trolley in the conveying process; when more goods need to be conveyed or the length of the goods exceeds the length of the first bottom plate 1, the ball plungers 8 at the front ends of the 2 telescopic rods 6 are pressed down, the first bottom plate 1 and the third bottom plate 29 are pulled simultaneously, so that the telescopic rods 6 are pulled out from the first bottom plate 1 until the ball plungers 8 on the telescopic rods 6 enter the limiting holes 3 on one side far away from the third bottom plate 29, and at the moment, the limiting plates 7 on the telescopic rods 6 just abut against one ends, far away from the third bottom plate 29, of the sliding grooves 2 in the corresponding positions; then, the second bottom plate 15 is lifted upwards, the hinge rod 16 at the lower end of the second bottom plate 15 moves upwards for a certain distance in the first limit groove 14 on the inner side of the vertical rod on the two sides of the n-shaped handrail 12, so that the baffle 17 welded at the upper end of the second bottom plate 15 is separated from the limit frame 13 on the n-shaped handrail 12, the second bottom plate 15 is placed downwards until the hinge rod 16 enters the containing groove 18 formed in the connecting plate 9, and then the second bottom plate 15 is rotated so that the baffle 17 at the upper end of the second bottom plate 15 is in contact with the limit rod 22 between the 2 telescopic rods 6; because two ends of the limiting rod 22 are respectively welded with the sliding seats 21 at corresponding positions, the sliding seats 21 can slide on the limiting posts 20 in the limiting groove II 19, and when the baffle 17 at the upper end of the second bottom plate 15 is in contact with the limiting plate 7, the second bottom plate 15 is pressed down by force to enable the second bottom plate 15 to be flatly laid on the telescopic rod 6; when the second bottom plate 15 is pressed downwards, the limiting rod 22 is extruded by the baffle plate 17 to move towards the direction far away from the first bottom plate 1 along the limiting column 20, and after the second bottom plate 15 is attached to the telescopic rod 6, the limiting rod 22 moves towards the direction close to the first bottom plate 1 by the elasticity of the pressure spring 23 until the limiting rod abuts against the baffle plate 17; the front end of the baffle 17 is provided with a bend which is matched with the limiting rod 22 to prevent the second bottom plate 15 from shaking in the cargo conveying process to influence the cargo space transportation stability; after the second bottom plate 15 is placed down, the second bottom plate and the first bottom plate 1 are on the same horizontal plane, articles with longer widths can be placed conveniently, the problem that the trolley is inconvenient to carry due to unstable gravity center when carrying the articles with the longer widths can be solved, meanwhile, more smaller and lighter goods can be carried, and the problem that the space between the telescopic rods 6 enables the smaller articles to fall off from the space in the carrying process, and inconvenience is brought to carrying is solved.

After the goods are transported, the limiting rod 22 is pulled to separate the baffle 17 on the second bottom plate 15 from the limiting plate 7, then the second bottom plate 15 is rotated to enable the second bottom plate 15 to return to the initial position, and the baffle 17 at the upper end of the second bottom plate 15 is hung on the limiting frame 13; simultaneously, pressing the ball plungers 8 on the side surfaces of the 2 telescopic rods 6, and putting the telescopic rods 6 back into the first bottom plate 1; for carrying convenience, the lower ends of the vertical rods on the two sides of the n-shaped handrail 12 are respectively hinged with the fixing seats 11 at corresponding positions and are clamped and fixed with the clamping grooves 24 on the fixing seats 11 through the T-shaped sliding blocks 27. When goods are conveyed, the n-shaped handrail 12 is vertically placed, and one end, positioned outside the third limiting groove 26, of the T-shaped sliding block 27 in the third limiting groove 26 outside the vertical rods on the two sides of the n-shaped handrail is clamped with the clamping groove 24 on the upper surface of the fixing seat 11, so that the n-shaped handrail 12 cannot shake forwards and backwards; after the goods are transported, the pull ring 28 is pulled by hand to separate the sliding block 27 from the slot 24 on the upper surface of the fixing base 11, then the n-shaped handrail 12 is rotated to make the n-shaped handrail 12 fall down towards one side of the first base plate 1 until the n-shaped handrail 12 is horizontally placed, and then one end of the sliding block 27, which is positioned outside the third limiting groove 26, enters the slot 24 on one side of the fixing base 11, which is close to the first base plate 1. When the trolley is folded, the trolley can be lifted by the handle 31, and the trolley is very convenient to carry. Because the lower end of the sliding block 27 is provided with the magnet 25, the fixed seat 11 is made of metal material which can attract the magnet 25, and the end of the sliding block 27, which is positioned outside the third limit groove 26, can be prevented from being separated from the clamping groove 24 when the hand handle 31 cart moves.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the utility model and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the utility model and various alternatives and modifications as are suited to the particular use contemplated.
