[0002] A tool cart is a container device used to store tools and can move, which can help workers save a lot of space. Usually, a table board is arranged on the top surface of the tool cart for placing utensils and for performing some operation tasks. Multiple drawers are arranged below the table board to realize the storage of utensils. The existing tool carts usually do not have a storage function above the table top. When an operator uses it, he can only take utensils from the drawers below, which is very inconvenient. Content of the Utility Model

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a tool cart function expansion structure. By setting a column base connected to the tool cart body and a column arranged on the column base, and the column extending beyond the top surface of the tool cart body to form an extended installation part, so the operator can install function expansion parts on the extended installation part to effectively utilize the space above the tool cart. The utility model also provides a peripheral mechanism of a tool cart and a tool cart.

[0004] In order to achieve the above purpose, the following technical solutions are adopted by the utility model to implement:

[0005] A tool cart function expansion structure is used to be arranged on a tool cart body and includes a column base and a column. The column base is used to be installed on the tool cart body. One end of the column is connected to the column base to form a column installation end, and the other end extends away from the top surface of the tool cart body to form a column extension end. And the distance from the column extension end to the bottom surface of the tool cart body is greater than the distance from the top surface of the tool cart body to the bottom surface of the tool cart body. The part of the column extending beyond the top surface of the tool cart body forms an extended installation part, and a first extended installation structure for installing function expansion parts is arranged on the extended installation part.

[0006] With the above structure, when the column is installed on the tool cart body by relying on the column base, the extended installation part on the column extends beyond the top surface of the tool cart body. Therefore, the user can install function expansion parts above the top surface of the tool cart body to increase the user's usage methods and make the tool cart body more in line with the user's usage requirements. The function expansion parts can be storage boxes or hanging plates, as long as the function expansion parts are provided with a second extended installation structure matching the first extended installation structure. The above structure can greatly increase the practicability and is convenient for the user.

[0007] Further, the column and the column base are detachably connected.

[0008] With the above structure, the practicability of the functional expansion structure of the tool cart is greatly enhanced, enabling the user to have options. When the user does not need to set up a functional expansion member above the top surface of the tool cart body, there is no need to install the column on the column base or disassemble the column from the column base, thus avoiding the column from affecting the user's operation. When the user needs to set up a functional expansion member above the top surface of the tool cart body, only need to install the column on the column base, and the user can install the functional expansion member on the column for easy use.

[0009] Furthermore, a first column installation structure is provided on the column base. Correspondingly, a second column installation structure is provided on the column. The column is detachably installed on the column base through the second column installation structure and the first column installation structure.

[0010] With the above structure, the structures of the column base and the column are more reasonable, facilitating the detachable connection between the two.

[0011] Furthermore, when the column base is installed on the tool cart body, the first column installation structure is provided on the side facing the top surface of the tool cart body. When the column is placed along the height direction of the tool cart body, the second column installation structure is provided on the side facing the bottom surface of the tool cart body.

[0012] One of the first column installation structure and the second column installation structure is configured as a first pair of slots, and the other of the first column installation structure and the second column installation structure is configured as a plug block or a second pair of slots that can be inserted and matched with the first pair of slots.

[0013] With the above structure, the detachable connection between the column base and the column is achieved through the insertion and matching of the first pair of slots and the plug block or through the insertion and matching of the first pair of slots and the second pair of slots. The above structure is simple and easy to operate, facilitating the disassembly operation during the user's use. Preferably, the other of the first column installation structure and the second column installation structure is configured as the second pair of slots, and the insertion and matching of the first pair of slots and the second pair of slots make the connection between the two more stable and reliable.

[0014] Further, the first pair of slots includes first and second pairs of slot sidewalls arranged oppositely. One end of the first pair of slot sidewalls is connected to the first pair of slot bottoms of the first pair of slots, and one end of the second pair of slot sidewalls is connected to the first pair of slot bottoms of the first pair of slots. A first pair of slot openings of the first pair of slots is formed between the other ends of the first pair of slot sidewalls and the second pair of slot sidewalls. One side of the first pair of slot sidewalls facing the first pair of slot openings and / or one side of the second pair of slot sidewalls facing the first pair of slot openings is formed as a first guiding portion for guiding insertion into the first pair of slots;

[0015] The second pair of slots includes third and fourth pairs of slot sidewalls arranged oppositely. One end of the third pair of slot sidewalls is connected to the second pair of slot bottoms of the second pair of slots, and one end of the fourth pair of slot sidewalls is connected to the second pair of slot bottoms of the second pair of slots. A second pair of slot openings of the second pair of slots is formed between the other ends of the third pair of slot sidewalls and the fourth pair of slot sidewalls. One side of the third pair of slot sidewalls facing the second pair of slot openings and / or one side of the fourth pair of slot sidewalls facing the second pair of slot openings is formed as a second guiding portion for guiding insertion into the second pair of slots.

[0016] With the above structure, the provision of the first guiding portion and the second guiding portion enables the user, when installing the column onto the column base, not to precisely align the first column installation structure and the second column installation structure. Even if there is a slight deviation, it can be corrected and inserted into a mating position by relying on the first guiding portion and the second guiding portion, facilitating the actual use by the user.

[0017] Further, when one side of the first pair of slot sidewalls facing the first pair of slot openings is formed as the first guiding portion, along the direction from the first pair of slot bottoms to the first pair of slot openings, the first guiding portion on the first pair of slot sidewalls gradually inclines away from the midline side of the first pair of slots, that is, the first guiding portion on the first pair of slot sidewalls gradually inclines away from the side of the second pair of slot sidewalls;

[0018] When one side of the second pair of slot sidewalls facing the first pair of slot openings is formed as the first guiding portion, along the direction from the first pair of slot bottoms to the first pair of slot openings, the first guiding portion on the second pair of slot sidewalls gradually inclines away from the midline side of the first pair of slots, that is, the first guiding portion on the second pair of slot sidewalls gradually inclines away from the side of the first pair of slot sidewalls;

[0019] When the side wall of the third pair of slots facing the opening of the second pair of slots is formed as the second guiding portion, along the direction from the bottom surface of the second pair of slots to the opening of the second pair of slots, the second guiding portion on the side wall of the third pair of slots gradually inclines away from the middle line side of the second pair of slots, that is, the second guiding portion on the side wall of the third pair of slots gradually inclines away from the side wall of the fourth pair of slots;
