Description

Technical Field

[0001] This application relates to the field of utility carts, and more particularly to a folding utility cart. Background Technology

[0002] A tool cart is a storage rack used in a production site to hold tools and parts. In order to hold more tools, it is usually made into a multi-layer structure, which takes up a lot of space and is very inconvenient to carry. Utility Model Content

[0003] This utility model provides a folding tool cart to solve the problem of inconvenience in carrying existing tool carts.

[0004] The present invention adopts the following technical solution:

[0005] A folding tool cart includes a column, at least two layers of folding tool storage boxes, a connecting rod, and at least two connecting plates. Each layer of folding tool storage boxes is mounted on the column and includes at least two storage box units, which are rotatably connected by a connecting shaft. The connecting rod is vertically arranged, and the connecting shaft of each layer of folding tool storage boxes is rotatably connected to one end of a connecting plate. The other end of the connecting plate is rotatably connected to the connecting rod. The folding tool cart also includes a safety lock plate, one end of which is rotatably connected to the uppermost folding tool storage box, and the other end is freely rotatable. The safety lock plate engages with a connecting screw connected to the uppermost connecting plate and the connecting rod to lock the folding tool cart in its unfolded state.

[0006] The folding tool cart has a folding handle, which is connected to a connecting rod.

[0007] The top folding tool storage box has a groove, and the folding handle is located in the groove. The folding handle is rotatably connected to the connecting shaft of the top folding tool storage box.

[0008] The connecting rod is connected to the folding handle via an extended connecting screw.

[0009] Rollers are installed at the bottom of the column.

[0010] The folding tool storage box is connected to the column by connecting screws.

[0011] The folding tool cart also includes a push handle, which is fixed to the upright.

[0012] When the folding tool cart is unfolded, the safety lock plate engages with the top connecting screw to lock all storage compartments in the unfolded state. To fold, simply rotate the safety lock plate to disengage it from the connecting screw, thus releasing the lock and allowing the folding operation to begin.

[0013] When folding, the folding handle rotates upward, which in turn drives the connecting rod, the top connecting piece, and the top connecting shaft to rotate upward. This also drives the connecting pieces of the other layers upward. The connecting pieces are connected to the storage box units of the other layers. Therefore, when the folding handle is pulled upward, it drives the connecting rod, and all layers of folding tool storage boxes rotate with the connecting rod, thus achieving quick folding and storage.

[0014] When the folding handle is turned downwards, it drives the connecting rod and connecting plate, and all the tool storage boxes in all layers rotate with the connecting rod, thus enabling the folding tool cart to unfold quickly.

[0015] The folding tool cart provided by this utility model effectively reduces the size of the tool cart by setting each layer of folding tool storage box as a foldable structure, making it easy to carry. It solves the problem that most existing tool carts are one-piece fixed structures, which are very large and inconvenient to move during mobile maintenance.

[0016] The connecting parts of each layer of the folding tool storage box are designed with teeth, and the interlocking teeth provide high connection strength and stability. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment illustrates the folding tool cart of this application using a three-layer folding tool storage box, with each layer containing two storage box units. The storage box units are: upper left storage box unit 2, upper right storage box unit 4, middle left storage box unit 12, middle right storage box unit 10, lower left storage box unit 13, and lower right storage box unit 16. Of course, depending on the needs, the folding tool cart can have two or more layers, and each layer can also use multiple storage box units. These embodiments do not exceed the protection scope of this application.

[0027] like Figure 1-6 As shown, a folding tool cart includes four uprights 9, three layers of folding tool storage boxes, connecting rods, and three connecting pieces. Each layer of the folding tool storage box is mounted on the four uprights 9 at its four corners via connecting screws 5. The upper layer of the folding tool storage box includes an upper left storage box unit 2 and an upper right storage box unit 4, which are rotatably connected via a connecting shaft 6. The middle layer of the folding tool storage box includes a middle left storage box unit 12 and a middle right storage box unit 10, connected via a connecting shaft. The lower folding tool storage box, comprising a lower left storage box unit 13 and a lower right storage box unit 16, is rotatably connected via a connecting shaft 20. A connecting rod 17 is vertically positioned; one end of a connecting piece 7 is fitted onto the connecting shaft 6, and the other end is rotatably connected to the connecting rod 17. Similarly, one end of a connecting piece 11 is fitted onto the connecting shaft 19, and the other end is rotatably connected to the connecting rod 17.
