Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically relating to a hardware processing tool cart. Background Technology

[0002] A hardware processing tool trolley is a device used for moving and storing hardware tools. It is usually made of metal and is sturdy and durable. The tool rack on the trolley can hold various hardware tools, such as hammers, screwdrivers, wrenches, etc., making it convenient for workers to quickly find the tools they need.

[0003] The height of the guard plate on the outer frame of some existing hardware processing tool trolleys is generally limited. When a large number of tools are placed on the tray and stacked to a certain height, the tools at the top are prone to falling off due to the lack of guard plate restraint and accidental contact with external force, which is quite inconvenient.

When a large number of tools are placed on the tray and stacked to a certain height, the tools at the top are prone to falling off after being accidentally touched by external force due to the lack of guard plate restraint, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hardware processing tool trolley, including a tray, wherein several trays are symmetrically arranged, and each adjacent tray is fixedly connected to a support frame, and several support frames are symmetrically arranged. A base plate is fixedly connected to the bottom of one of the trays, and a caster wheel is fixedly connected to the bottom of the base plate. Several caster wheels are symmetrically arranged. A protective plate is fixedly connected to the outer side of each tray, and a screw is threadedly connected to the inner side of each protective plate. Several screws are symmetrically arranged, and a pressure ring is fixedly connected to the outer side of one end of each screw. An expansion frame is movably connected to the outer side of each screw through a limiting hole, and the limiting hole is U-shaped.

[0006] Preferably, one of the trays is fixedly connected to the top of a partition, and several partitions are symmetrically arranged, with protective plates fixedly connected to both sides of each partition.

[0007] Preferably, each side of the expansion frame is fixedly connected with a hook, and several hooks are symmetrically arranged, all of which are U-shaped structures.

[0010] Preferably, each screw is movably connected to a washer on its outer side, and the washer is located on one side of the pressure ring and the expansion frame.

[0011] Preferably, each side of the expansion frame is fixedly connected to a slide bar, and several slide bars are symmetrically arranged. Each slide bar is slidably connected to a protective plate on its outer side.

[0012] Preferably, the outer surfaces of the tray, stand, guard plate, and extension frame are all provided with an electroplated anti-oxidation coating.

[0014] Beneficial effects:

[0015] 1. This utility model features an expansion frame with screws movably connected to its inner side via limiting holes. A pressure ring is fixedly connected to the outer side of each screw, and a protective plate is threaded onto the outer side of each screw. Based on the required stacking height of tools on the top of the tray during hardware processing, by squeezing the knob and rotating counter-clockwise to loosen the screw, the U-shaped limiting holes raise each expansion frame to the required height outside the protective plate. Finally, rotating the screw clockwise, the pressure ring's pad limits and fixes the expansion frame's height, thus protecting the tools' perimeter. This effectively expands the protective height for tools, increasing the protective area when the tools are stacked high on the top of the tray, thereby effectively reducing the risk of tools at the top falling due to accidental contact with external forces.

[0016] 2. This utility model features a knob with a pressure ring fixedly connected to one side, a screw fixedly connected to the inner side of the pressure ring, and a protective plate threaded to the outer side of the screw, which allows for easy gripping and rotation by personnel. Additionally, hooks with U-shaped structures and an extension frame fixedly connected to one side of each hook facilitate hanging of tools. Attached Figure Description

[0026] Please see Figures 1-6 This utility model provides a technical solution: a hardware processing tool trolley, including a tray 1, several trays 1 are symmetrically arranged, and each adjacent tray 1 is fixedly connected to a support frame 2, several support frames 2 are symmetrically arranged, a base plate 3 is fixedly connected to the bottom of one tray 1, a caster wheel 4 is fixedly connected to the bottom of the base plate 3, several caster wheels 4 are symmetrically arranged, a protective plate 5 is fixedly connected to the outer side of each tray 1, a screw 6 is threadedly connected to the inner side of each protective plate 5, several screws 6 are symmetrically arranged, a pressure ring 7 is fixedly connected to the outer side of one end of each screw 6, and an expansion frame 9 is movably connected to the outer side of each screw 6 through a limiting hole 8. All holes 8 are U-shaped structures. Based on the required stacking height of tools on the top of tray 1 in hardware processing, after pinching the knob 14, rotate it counterclockwise and loosen the screw 6. Then, in conjunction with the U-shaped limiting holes 8, each extension frame 9 is raised to the required height on the outside of the guard plate 5. Finally, rotate the screw 6 clockwise, and the expansion frame 9 is squeezed and limited by the gasket 13 on one side of the pressure ring 7, fixing the height of the expansion frame 9 and protecting the periphery of the tools. This can effectively expand the protection height of the tools. When the stacking height of tools on the top of tray 1 is large, the protection area is expanded, thereby effectively reducing the risk of tools located on the top falling due to accidental contact with external forces.

[0027] In this utility model, preferably, a partition 10 is fixedly connected to the top of one of the trays 1, and several partitions 10 are symmetrically arranged. Protective plates 5 are fixedly connected to both sides of the partitions 10, effectively dividing the storage space. Hooks 15 are fixedly connected to one side of each expansion frame 9, and several hooks 15 are symmetrically arranged. All hooks 15 have a U-shaped structure, which facilitates hanging tools. Handles 12 are fixedly connected to the other side of each expansion frame 9, and several handles 12 are symmetrically arranged, which facilitates gripping and pushing the device. A knob 14 is fixedly connected to one side of each lifting expansion frame 9 and pressure ring 7, and several knobs 14 are symmetrically arranged. Each pressure ring 7 has a screw 6 fixedly connected to its inner side, and a protective plate 5 threadedly connected to the outer side of each screw 6, which facilitates rotation after being gripped by a person. Each screw 6 has a movably connected washer 13 on its outer side, which is located on one side of the pressure ring 7 and the expansion frame 9, which can effectively ensure the stability of the screw 6 during long-term use. Each expansion frame 9 has a slide bar 11 fixedly connected to one side, and several slide bars 11 are symmetrically arranged. Each slide bar 11 has a protective plate 5 slidably connected to its outer side, which can effectively ensure the stability of the expansion frame 9. The outer surfaces of the tray 1, the stand 2, the protective plate 5 and the expansion frame 9 are all provided with an electroplated anti-oxidation coating, which can effectively reduce the risk of material strength reduction caused by oxidation and corrosion.

[0028] The working principle and usage process of this utility model are as follows: When in use, according to the required stacking height of the tools in the hardware processing on the top of the tray 1, after pinching the knob 14, rotate it counterclockwise and loosen the screw 6. Then, with the help of the U-shaped limiting hole 8, each extension frame 9 is raised to the required height on the outside of the guard plate 5. Finally, rotate the screw 6 clockwise, and the expansion frame 9 is squeezed and limited by the gasket 13 on one side of the pressure ring 7, thus fixing the height of the expansion frame 9 and protecting the periphery of the tools. This can effectively expand the protection height of the tools. When the stacking height of the tools on the top of the tray 1 is large, the protection area is expanded, thereby effectively reducing the risk of the tools located on the top falling due to accidental contact with external forces.
