Description

Technical Field

[0001] This utility model relates to the technical field of tool and workpiece placement devices, and more specifically, to a tool cart. Background Technology

[0002] A tool cart is a device used to place tools or workpieces. Currently, tool carts on the market mainly consist of an upper tray, a lower tray, and four uprights spaced circumferentially. The lower end of each upright is fixed to the outer wall of the lower tray by a first bolt, which bears all the load of the upright. The upper end of each upright is fixed to the outer wall of the upper tray by a second bolt, which also bears all the load of the upper tray. However, with the above structure, there are obvious drawbacks: the uprights have poor reliability in supporting the upper tray, and the lower tray has poor reliability in supporting the uprights. This results in poor structural stability and poor load-bearing capacity of the tool cart. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tool cart with the advantages of high structural stability and strong load-bearing capacity.

[0004] This utility model provides a tool cart, including an upper tray, a lower tray, and four uprights spaced circumferentially. Each upright has an "L"-shaped cross-section. Each upright has an inwardly folded bend at the outer edge of its two sides. The lower ends of the two bends on each upright are supported on the upper ends of the two sides at one corner of the lower tray, and the upper ends of the two bends on each upright are supported on the bottom of the two sides at one corner of the upper tray.

[0005] By adopting the above-described structure, this utility model allows the lower end of the column to be supported on the upper end of the lower pallet via the bending section, while the upper end of the bending section supports the upper pallet. This enables the lower pallet to reliably support the column, and the column to reliably support the upper pallet, thereby increasing the upper pallet's load capacity. In other words, it has the advantages of high reliability in supporting the column from the lower pallet, and high reliability in supporting the upper pallet from the column. This improves the structural stability and load-bearing capacity of the tool cart.

[0006] In one possible implementation, the cross-section of the bend forms a "V" shape; by adopting this shape, the structural strength of the bend can be further improved, and the bend can be reliably supported on the upper end of the side of the lower pallet. In addition, the bend can reliably support the upper pallet to improve the load-bearing capacity of the upper pallet.

[0007] In one possible implementation, each column has two first connecting wings formed on its upper end. Each first connecting wing has at least two horizontally spaced first connecting holes. The two sides of each corner of the upper tray are fastened to the corresponding column by first bolts threaded through the first connecting holes and connected to the upper tray. With this structure, the upper tray can be reliably fastened to the column. After each first connecting wing is fastened to the side of the upper tray by the first bolts threaded through the first connecting holes on the corresponding first connecting wing, the support point of the upper tray and the bending part on the side of the first connecting wing, as well as the first bolts on the first connecting wing, can form a triangular structure, thereby further improving the fixing strength and stability of the upper tray and the column.

[0008] In one possible implementation, two side edges at the lower end of each column form second connecting wings. Each second connecting wing has at least two horizontally spaced second connecting holes. The two side edges at each corner of the lower tray are fastened to the corresponding column by second bolts threaded through the second connecting holes and connected to the lower tray. With this structure, the column can reliably support and fix itself to the upper end of the lower tray. After each second connecting wing is fastened to the side edge of the upper tray by second bolts threaded through the second connecting holes on the corresponding second connecting wing, the support point of the lower tray and the bend on the side where the second connecting wing is located, as well as the second bolts at the second connecting wing, can form a triangular structure, thereby further improving the fixing strength and stability of the column and the lower tray.

[0009] In one possible implementation, at least one intermediate tray is provided between the upper and lower trays. Each upright has a break corresponding to the horizontal level of each intermediate tray on its two bends. The bottom of one corner of each intermediate tray is supported by the upper end of the bend below the corresponding break, and the lower end of the bend above the break is supported by the upper end of the corresponding intermediate tray. With this structure, the upper end of the bend below the break can reliably support one corner of the intermediate tray, and the upper end of the intermediate tray can reliably support the lower end of the bend above the break. In addition, the storage space of the tool cart can be increased by the intermediate tray.

[0010] In one possible implementation, at least two horizontally spaced third connecting holes are provided on the side wall of the column at each location of the break. The two sides of each corner of the intermediate tray and the corresponding column are fastened to the intermediate tray by third bolts that pass through the third connecting holes and are threaded to the intermediate tray. With this structure, the intermediate tray can be reliably fastened to the column, and the third bolts on the same side of the column and the support points of the intermediate tray and the bend can form a triangular structure, thereby further improving the fixing strength and stability of the intermediate tray and the column.

[0011] In one possible implementation, a recessed guide groove is provided on the inner bottom of both the upper tray and / or the middle tray. A connecting joint is connected to the bottom of the guide groove, and the lower end of the connecting joint is connected to the cutting fluid recovery tank through a guide pipe. With this structure, due to the provision of the guide groove and the connecting joint, when the workpiece or material is placed on the upper tray and / or the middle tray, the cutting fluid flowing down from the workpiece or material can be recovered into the cutting fluid recovery tank through the guide pipe, thereby enabling the reuse of the cutting fluid and avoiding waste of the cutting fluid.

[0012] In one possible implementation, the guide channel is a ring-shaped structure; by adopting a guide channel with this structure, the guide channel can more effectively and reliably guide the cutting fluid located on the bottom of the upper tray and / or the middle tray to the connecting joint, and the cutting fluid can flow back to the cutting fluid recovery tank through the connecting pipe; in addition, the edge of the guide channel is close to the edge of the inner bottom of the upper tray and / or the edge of the inner bottom of the middle tray.

[0013] In one possible implementation, each side of the upper tray, lower tray, and middle tray has an inwardly folded edge at its upper end; each folded edge includes a horizontal section and an inclined section; the horizontal section is formed by bending the upper ends of the upper tray side, lower tray side, and middle tray side inward horizontally, and the inclined section is formed by bending the inner end of the horizontal section from top to bottom outward; by providing the folded edges, the overall structural strength and deformation resistance of the upper tray, lower tray, and middle tray can be improved, that is, the structural strength and deformation resistance of the upper tray, lower tray, and middle tray can be enhanced. The load-bearing capacity of the pallet is improved. Furthermore, since the horizontal section is formed by bending inward horizontally from the upper end of the side of the upper pallet, the upper end of the side of the lower pallet, and the upper end of the side of the middle pallet, and the inclined section is formed by bending outward from the inner end of the horizontal section from top to bottom, the folded edges can effectively prevent the user's hands from being scratched when the staff picks up or puts down the workpieces or materials in the upper, lower, and middle pallets. Under the action of this folded edge, the structural strength and deformation resistance of the upper, lower, and middle pallets can be further improved, thereby improving the load-bearing capacity of the upper, lower, and middle pallets.

[0014] In one possible implementation, the tool cart further includes a back panel, a storage tray, and two symmetrically arranged support columns; the lower ends of the two support columns are fixed to the rear side of the upper tray and the upper ends of the two columns located at the rear side; the back panel is fixed to the front side of the upper ends of the two support columns; the storage tray is disposed on the front side of the lower part of the back panel; connecting ears are integrally formed on the rear sides of both ends of the storage tray; at least two vertically spaced fourth connecting holes are provided on the connecting ears; the storage tray and the back panel are fastened by fourth bolts passing through the fourth connecting holes and threaded to the side of the back panel; at least one folder is fixed to the front side of the upper part of the back panel; the lower tray... Casters are attached to each corner of the outer bottom. With this structure, the two connecting ears are integrally formed on the rear side of the storage tray, resulting in high connection strength between the connecting ears and the storage tray, as well as high connection strength between the storage tray and the back panel. Furthermore, the rear edge of the storage tray abuts against the front side of the back panel, further enhancing the connection strength between the storage tray and the back panel, and increasing the load-bearing capacity of the storage tray. The folder configuration allows users to store documents between the folder and the back panel, such as process flow documents, providing convenience for users. Attached Figure Description
