For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or there can be communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] See the appendix Figures 1-4 , as shown is a tool cart, including a chassis 1, wherein the chassis 1 is welded by rectangular steel pipes, and the chassis 1 as a whole is in an H-shaped structure. A self-locking universal wheel 2 is provided at each of the four corners of the chassis 1. The chassis 1 includes a first intermediate beam 6. A first load-carrying frame 18 is provided on each side of the chassis 1 located at the first intermediate beam 6. A rubber pad is laid in the first load-carrying frame 18. When in use, some large or heavy tools can be placed in the first load-carrying frame 18. In this way, the center of gravity of the entire tool cart is lowered by the weight of the tools, thereby improving the stability of the tool cart during the moving process;

[0029] A first connecting frame 8 is welded at one-third of the length of the first intermediate beam 6. A column 3 is installed in the first connecting frame 8. And at the joint of the first connecting frame 8 and the column 3, a first pin screw A 10 and a first pin screw B 11 are arranged along the axial direction. Corresponding to the positions of the first pin screw A 10 and the first pin screw B 11 at the joint of the first connecting frame 8 and the column 3, first pin holes are opened. When storing, the first pin screw B 11 is pulled out from the first pin hole. At this time, the column 3 can rotate along the first pin screw A 10 and fit to one side of the first intermediate beam 6;

[0030] It should be noted that in order to further reduce the length and width of the tool cart during storage, the length of the column 3 is equal to two-thirds of the length of the first intermediate beam 6. In this way, when the column 3 is stored, it is flush with one end of the first intermediate beam 6, avoiding being too long;

[0031] Furthermore, a support column 4 can be telescopically sleeved in the column 3, and a locking bolt 22 is provided on the column 3 to fix the position of the support column 4 in the column 3. And the top of the support column 4 is welded with a second connecting frame 9, and a load-carrying rack 5 is provided on the second connecting frame 9;

[0032] The load-carrying rack 5 includes a second intermediate beam 7. The second intermediate beam 7 is located in the second connecting frame 9. At the joint of the second connecting frame 9 and the second intermediate beam 7, a second pin screw A 12 and a second pin screw B 13 are arranged along the axial direction, and corresponding to the positions of the second pin screw A 12 and the second pin screw B 13 at the joint of the second connecting frame 9 and the second intermediate beam 7, second pin holes are also opened;

[0033] It can be seen from this that when the tool cart is stored and transported, the detachable connection of the chassis 1, the column 3, and the load-carrying rack 5 is realized through the first connecting frame 8, the second connecting frame 9, the first pin screw A 10, the first pin screw B 11, the second pin screw A 12, and the second pin screw B 13. It can be transported and stored in the form of loose parts, greatly reducing the space occupation, and at the same time increasing the quantity of tool carts transported and stored in a unit space;

[0034] Furthermore, the load-carrying rack 5 is also provided with a second load-carrying frame 19 through the second intermediate beam 7. The edge of the second load-carrying frame 19 is provided with a cold-formed enclosure 20, and the enclosure 20 is provided with a plurality of tool hanging interfaces 21 of different types. Tools such as screwdrivers can be classified and placed through the tool hanging interfaces 21, which is convenient for the staff to pick up and place;

[0035] Furthermore, in order to increase the stability of the column 3 on the first intermediate beam, a first cold-formed support member 14 is welded to one end of the column 3 close to the first intermediate beam 6. A first fixing bolt 16 is provided between the first cold-formed support member 14 and the first intermediate beam 6. After the column 3 is erected on the first intermediate beam 6, a supporting effect is provided for the column 3 through the first cold-formed support member 14 and the first fixing bolt 16, thus increasing the stability and supporting strength of the column 3;

[0036] At the same time, a second cold-formed support member 15 is provided at one end of the support column 4 close to the second intermediate beam 7. A second fixing bolt 17 is provided between the second cold-formed support member 15 and the second intermediate beam 7. The stability and supporting strength of the load-carrying rack 5 are improved through the second cold-formed support member 15.

[0037] The beneficial effects of the present utility model are as follows: When transporting and storing, first remove the second pin screw A 12 and the second pin screw B 13 from the second connecting frame 9, and at the same time take out the second fixing bolt 17. At this time, the entire load-carrying rack 5 can be removed from the support column 4. Then remove the first pin screw B 11 and the second fixing bolt 17, so that the column 3 can rotate around the first pin screw A 10 and fit onto the first intermediate beam 6. At this time, the height and volume of the entire tool cart are reduced, enabling more tools to be placed in a unit space, providing more space for storage and increasing the quantity of tool carts transported at one time, reducing the number of transports, and lowering the transportation cost.

[0038] The above is only the preferred specific embodiment of the present utility model, and does not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
