Description

Technical Field

[0001] This utility model relates to an industrial toolbox cabinet, and more particularly to a heavy-duty toolbox cabinet with lifting lugs. Background Technology

[0002] Currently, most industrial toolboxes and cabinets on the market are made of metal (such as cold-rolled steel), with a sturdy structure and strong load-bearing capacity. With the continuous development of industrial production needs, the size and capacity of toolboxes and cabinets are increasing, leading to a significant increase in their weight, which can reach hundreds of kilograms or even higher. In practical use, to save space, multiple toolboxes and cabinets are often stacked vertically. Existing technologies for stacking heavy-duty toolboxes and cabinets mainly present the following problems: 1. Difficult to handle manually: Relying entirely on manual stacking is extremely difficult and poses a significant safety hazard, easily causing back injuries or crush injuries to operators; 2. Cumbersome disassembly: Some users have to remove all detachable parts such as drawers and shelves from the cabinet to reduce the overall weight before handling and stacking, a time-consuming and labor-intensive process that greatly reduces work efficiency; 3. Lack of dedicated lifting structure: Existing toolboxes and cabinets are usually not designed with dedicated and reliable lifting points. If users use ropes or slings to tie the cabinet for lifting, it is very easy for the cabinet to slip or become unhooked, causing it to bump, deform, or even fall, posing a very high safety risk.

[0003] Therefore, there is an urgent need in this field for a technical solution that can solve the problem of safe and convenient stacking of heavy toolboxes and cabinets. Summary of the Invention

[0004] This utility model provides a heavy-duty toolbox cabinet with lifting lugs; it solves the problem in the prior art that the lack of a dedicated lifting structure for heavy-duty toolbox cabinets leads to difficulties in handling and stacking, as well as high safety risks.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a heavy-duty toolbox cabinet with lifting lugs, comprising a heavy-duty toolbox cabinet body, side panels on the left and right sides of the heavy-duty toolbox cabinet body, and lifting lug modules symmetrically arranged on the top surface of the two side panels. Each lifting lug module consists of a guide seat, a lifting block, a load-bearing limiting component, and a rebound mechanism module. The guide seat is embedded and fixed to the top surface of the side panel, and a vertically guiding sliding cavity is formed inside the guide seat. The lifting block is slidably installed in the sliding cavity, and the load-bearing limiting component... The side plate is fixed, and the rebound module is vertically fixed inside the side plate. The rebound module is provided with a telescopic rod that faces upward and abuts against the lifting block. The telescopic rod can push the lifting block to slide upward. During the upward sliding process, the lifting block is provided with an abutment part that can abut against the load-bearing limit member. The upper end of the lifting block forms a lifting lug structure. When the abutment part abuts against the load-bearing limit member, the lifting lug structure extends out from the sliding cavity. When the telescopic rod is fully retracted, the lifting lug structure retracts back into the sliding cavity.

[0006] The lifting block, load-bearing limiting component, and the fixing part of the load-bearing limiting component in this utility model are all load-bearing parts, thus requiring high structural strength. The lifting block in this utility model can slide up and down along the sliding cavity defined within the guide seat. Simultaneously, the bottom of the lifting block abuts against the telescopic rod of the rebounder module. The telescopic rod on the rebounder module has an elastic extension and retraction effect; continuous pressing of its end allows for alternating extension and retraction. Therefore, when the telescopic rod is in the retracted state, the lifting block slides down under its own weight until it abuts against the telescopic rod, at which point the entire lifting block retracts into the sliding cavity. When the lifting block is pressed again, the telescopic rod switches to the extended state, pushing the lifting block upwards until the abutting part abuts against the load-bearing limiting component. At this point, the lifting lug structure at the upper end of the lifting block extends entirely from the sliding cavity. The lifting lug structure facilitates lifting, and can be used with gantry crane hooks or forklifts. Therefore, this utility model allows the lifting lug structure to extend or retract simply by pressing the upper surface of the lifting block. When the lifting lug structure extends, it is convenient to transport the utility model as a whole. After the transport is completed, the lifting lug structure can be retracted. In this way, other toolboxes and cabinets can be stacked on top of this utility model.

[0007] Therefore, this utility model has the following features compared with the prior art: 1. This utility model provides a standard and sturdy lifting lug structure, which can be directly connected to the forklift forks and hooks through the lifting straps, making the stacking operation of toolbox cabinets weighing hundreds of kilograms safe, simple and efficient, completely avoiding the risks of manual handling and the trouble of disassembling the interior;

[0008] 2. The hanging lugs can be completely retracted when not in use, flush with the side of the cabinet, without affecting the normal placement, movement, or aesthetics of the toolbox cabinet;

[0009] 3. The "one-click opening" design greatly simplifies the operation process, allowing users to quickly unfold and retract the rings without any tools, resulting in an excellent user experience. Attached Figure Description

[0015] Example 1: See Figure 1 , Figure 2 and Figure 3 A heavy-duty toolbox cabinet with lifting lugs includes a cabinet body 100, side panels 110 on the left and right sides of the cabinet body, and four lifting lug modules 200 symmetrically arranged on the top surface of the side panels. Each lifting lug module consists of a guide seat 210, a lifting block 220, a load-bearing limiting component 230, and a rebound module 240. The guide seat is embedded and fixed to the top surface of the side panel, and a vertically guiding sliding cavity is formed inside the guide seat. The lifting block is slidably installed in the sliding cavity, and the load-bearing limiting component 230 is used for the lifting lug module. The component is fixed relative to the side plate, and the rebound module is vertically fixed inside the side plate. The rebound module is provided with a telescopic rod 241 that is vertically upward and abuts against the lifting block. The telescopic rod can push the lifting block to slide upward. During the upward sliding process, the lifting block is provided with an abutment part 221 that can abut against the load-bearing limit component. The upper end of the lifting block forms a lifting lug structure 222. When the abutment part abuts against the load-bearing limit component, the lifting lug structure extends out from the sliding cavity. When the telescopic rod is fully retracted, the lifting lug structure retracts back into the sliding cavity.

[0016] In this embodiment, the lifting block, the load-bearing limiting component, and the fixing part of the load-bearing limiting component are all load-bearing parts, thus requiring high structural strength. The lifting block in this embodiment can slide up and down along the sliding cavity defined within the guide seat. Simultaneously, the bottom of the lifting block abuts against the telescopic rod of the rebounder module. The telescopic rod on the rebounder module has an elastic extension and retraction effect; continuous pressing of its end allows for alternating extension and retraction. Therefore, when the telescopic rod is in the retracted state, the lifting block slides down under its own weight until it abuts against the telescopic rod, at which point the entire lifting block retracts into the sliding cavity. When the lifting block is pressed again, the telescopic rod switches to the extended state, pushing the lifting block upwards until the abutting part abuts against the load-bearing limiting component. At this point, the lifting lug structure at the upper end of the lifting block extends entirely from the sliding cavity. The lifting lug structure facilitates lifting, and gantry crane hooks or forklifts can be used in conjunction with the lifting lug structure. Therefore, in this embodiment, the lifting lug structure can be extended or retracted simply by pressing the upper surface of the lifting block. When the lifting lug structure is extended, it is convenient to transport this embodiment as a whole. After the transport is completed, the lifting lug structure can be retracted. In this way, other toolboxes and cabinets can be stacked on top of this embodiment.

[0017] For details, see Figure 3 The lifting block is integrally formed by two vertical rods 223 and a horizontal rod 224. A connecting rod 225 is fixedly connected between the bottom of the two vertical rods. The telescopic rod abuts against the middle of the connecting rod. The upper ends of the two vertical rods and the horizontal rod constitute the above-mentioned lifting lug structure. The lifting block and the guide seat are both made of QT450-10 ductile iron, which has high strength and toughness.

[0018] For details, see Figure 3 Both vertical rods are equipped with vertically distributed sliding grooves 226. The load-bearing limiting components are two horizontal round shafts that pass through the sliding grooves. The diameter of the round shafts is 10mm and the material is No. 45 steel. The abutment part is located at the lower end of the sliding groove. The single-point static load capacity of this lifting lug module can reach 1000kg, which fully meets the lifting requirements of heavy toolbox cabinets.

[0019] For details, see Figure 2 The upper end of the guide seat is provided with a flange 212. The flange is attached to the fixed surface of the side plate and connected with bolts or rivets, preferably two 8.8 grade high-strength internal hex bolts.

[0020] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
