DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A trolley that is easy to assemble includes two bases 1 and a push rod 8. The two bases 1 are connected by a connecting plate 2. The connecting plate 2 is rotatably connected to the two bases 1. Two grasping rods are installed on the push rod 8. With the help of the above-mentioned connecting plate 2, the two bases 1 can be folded up to reduce the floor space occupied when they are stored. The grasping rods can be grasped one by one, so that it is more convenient to push the entire device with the help of the push rod 8.

[0025] Movable wheels 3 are provided under the two bases 1. The movable wheels 3 can also be universal wheels, so that the entire device can be moved in multiple directions.

[0026] A folding groove 4 is provided on the upper end faces of the two bases 1, and a fence 5 is provided in the folding groove 4 by rotation through an adsorption mechanism. The adsorption mechanism includes a bar magnet 6 arranged on the front and back sides of the fence 5. Iron bars corresponding to the bar magnet 6 are provided on the bottom wall and the inner side wall of the folding groove 4. One of the bar magnets 6 is installed above the front side of the fence 5, and the other bar magnet 6 is installed below the back side of the fence 5. The iron bars and the bar magnet 6 are used to ensure the stability of the fence 5 when it is vertical and flat.

[0027] A mounting groove 17 is provided on the outer wall of one of the bases 1, a rotating cavity 11 is provided inside the push rod 8, a screw 12 is rotatably provided in the rotating cavity 11, a rotating opening 9 is provided on the push rod 8, a rotating block 10 is rotatably provided on the bottom wall of the rotating opening 9, the rotating block 10 is connected to the screw 12 through a connecting shaft, and the rotating block 10 can drive the screw 12 to rotate with the help of the connecting shaft, thereby realizing the lifting and lowering operation of the lifting plate 13 in the rotating cavity 11.

[0028] A lifting plate 13 is provided on the threaded sleeve of the screw 12, and a vertical rod is provided in the rotating chamber 11. The vertical rod is arranged parallel to the screw 12, and the vertical rod slides through the lifting plate 13. The vertical rod is not shown in the accompanying drawings, and its function is to limit the position to prevent the lifting plate 13 from rotating with the screw 12.

[0029] A limiting groove 18 corresponding to the lifting plate 13 is provided on the inner bottom wall of the mounting groove 17, one of the bases 1 is provided with a movable groove 16 connected to the mounting groove 17, and a movable groove 19 is provided on the inner wall of the movable groove 16. A sliding rod 20 is provided in the movable groove 19, and a sliding sleeve 21 is provided on the sliding rod 20 through an elastic mechanism sliding sleeve, and an insert plate 7 is installed on the sliding sleeve 21. An insertion groove 15 corresponding to the insert plate 7 is provided on the other base 1, and the elastic mechanism includes a spring 22 that is slidably sleeved on the outside of the sliding rod 20, and both ends of the spring 22 are elastically connected to the outer wall of the sliding sleeve 21 and the inner wall of the movable groove 19 respectively. The above-mentioned spring 22 can drive the insert plate 7 to move back into the movable groove 16 and disengage from the insertion groove 15 with the help of the sliding sleeve 21 after the push rod 8 is disengaged from the mounting groove 17.

[0030] When the utility model is used, Figure 1 and Figure 2 In the state shown, the goods can be placed in the folding groove 4 and protected by the fence 5, the base 1 is moved by the moving wheels 3, and the base 1 is pushed and pulled by the push rod 8.

[0031] When the device needs to be folded and stored, first rotate the rotating block 10 in the rotating mouth 9, and the rotating block 10 drives the screw 12 to rotate. When the screw 12 rotates, the lifting plate 13 on its outer wall performs an ascending operation, and the lifting plate 13 rises and disengages from the limit groove 18, and then releases the fixed installation of the push rod 8, and moves the push rod 8 horizontally to complete its connection with the base 1. After the push rod 8 is disengaged from the installation groove 17, the insertion plate 7 loses the extrusion force. At this time, under the action of the spring 22, the elastic potential energy provided by the spring 22 drives the sliding sleeve 21 to move on the sliding rod 20, and drives the insertion plate 7 to move. The insertion plate 7 is disengaged from the insertion groove 15 and enters the movable groove 16 to complete the storage. At this time, the two bases 1 can complete the rotation and folding operation with the help of the connecting plate 2. Before folding, rotate the fence 5 to change it from a vertical state to a horizontal state, and use the bar magnet 6 to adsorb with the iron bar to ensure the folding stability.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
