Description

Technical Field

[0001] The utility model relates to the technical field of work tool boxes, in particular to a portable work box. Background Art

[0002] Traditional workbenches are often bulky and heavy, making them difficult to carry and unsuitable for outdoor work or temporary workspaces. While some portable workbenches exist on the market, they often suffer from complex structures, awkward operation, and poor load-bearing capacity.

[0003] For example, a conventional toolbox includes a box body and a top cover rotatably connected to the upper end of the box body. A slot is provided on each left and right side of the lower end of the box body. A locking plate is rotatably connected to each left and right side of the top cover. One end of the locking plate has a buckle strip. When two toolboxes are stacked together, the locking plate of one toolbox snaps into the slot of the other toolbox. The top of the top cover has an upward-opening accessory compartment. A first cover is rotatably connected to the upper end of the top cover for covering the accessory compartment. The accessory compartment is snapped with long spacers extending left and right and short spacers extending front and back, forming a plurality of grooves that separate the accessory compartments. This structure allows two toolboxes to be stacked together with the locking plate of one toolbox snapping into the slot of the other, thereby achieving the effect of securely stacking multiple toolboxes.

[0004] However, when using this toolbox, the toolbox needs to be placed on the ground and then opened. When working, the staff needs to squat or bend over many times to take and put tools, which increases the staff's fatigue and is not conducive to improving work efficiency. Or in order to make it more convenient to take and put tools, an additional tool table is needed to facilitate the placement of tools. This not only increases the weight of the staff, but is also quite inconvenient. Utility Model Content

[0024] The present invention will be further described in detail below with reference to specific implementation methods.

[0025] like Figures 1 to 5As shown, this embodiment discloses a portable work box, comprising a box body 1 for storing tools, a box cover 2 hinged on one side of the box body 1, and support frames 3 folded and installed on both sides of the box body 1. When the support frames 3 are unfolded, the box body 1 is erected to form a table; a drag box 11 that can be pulled out horizontally is provided on the box body 1, and a first storage space 12 for storing tools is provided on the drag box 11. A placement platform 10 for temporarily placing tools is provided on the top of the box body 1, and a second storage space 20 for storing tools is provided on the inner side of the box cover 2. When the box cover 2 is closed, the placement platform 10 is covered. Specifically, the placement platform 10 is recessed in the top of the box body 1. A groove is formed on the plane to prevent tools from rolling off the edge of the placement platform 10; a rotating seat 30 for installing the support frame 3 is provided on both sides of the box body 1, and the top of the support frame 3 is rotatably installed on the rotating seat 30. The rotating seat 30 is provided with a locking mechanism 31 for limiting the rotation angle of the support frame 3. The locking mechanism 31 can keep the support frame 3 in an expanded state or a folded state. When working, the support frame 3 can be unfolded to form a table for convenient access to tools. The staff does not need to squat or bend down many times to access tools, which saves the staff's physical strength and improves work efficiency. After the work is completed, the support frame 3 can be folded to reduce the occupied space and facilitate storage.

[0026] In this embodiment, the locking mechanism 31 includes a first limit pin 311 fixed on the rotating seat 30 and a second limit pin 312 movably mounted on the rotating seat 30; the support frame 3 is provided with a limit groove 320 for cooperating with the first limit pin 311 to abut against, and a limit hole 321 for the second limit pin 312 to be engaged. When the support frame 3 is unfolded, the limit groove 320 abuts against the first limit pin 311 to limit the unfolding angle of the support frame 3, and the second limit pin 312 passes through the limit hole 321 to keep the support frame 3 at the unfolding angle; specifically, the first limit pin 311, the second limit pin 312, the limit groove 320 and the limit hole 321 are each provided with two groups, and are symmetrically arranged on the left and right sides of the rotating seat 30 and the support frame 3.

[0027] Furthermore, in order to be able to control the second limit pin 312 to move and retract in the limit hole 321, a pin seat 301 is provided at the position of the limit hole 321 on the outer side of the rotating seat 30, and the second limit pin 312 passes through the pin seat 301 from the outside to the inside, and a return spring 302 is sleeved on the second limit pin 312 located on the inner side of the pin seat 301, and the return spring 302 presses on the second limit pin 312 to drive the second limit pin 312 to pass through the limit hole 321. When the support frame 3 needs to be folded, the second limit pin 312 can be pulled out to disengage from the limit hole 321 to release the lock on the limit hole 321, thereby facilitating the folding of the support frame 3.

[0028] In this embodiment, the support frame 3 includes a hinge portion 32 for being installed on the rotating seat 30 and a support portion 33 for supporting. There is an angle between the hinge portion 32 and the support portion 33, and the angle is preferably 90°. When the support frame 3 is folded, the hinge portion 32 is located on both sides of the box body 1, and the support portion 33 is close to the bottom of the box body 1. It can be determined that the limiting groove 320 and the limiting hole 321 are both arranged on the hinge portion 32. Specifically, the length of the support portion 33 is less than or equal to the length of the box body 1. After the support frames 3 on both sides are folded, the support portions 33 of the two groups of support frames 3 overlap in sequence.

[0029] Furthermore, in order to enable the support frame 3 to maintain a folded state, a second limiting hole 322 is also provided on the hinge part 32. When the support frame 3 is folded, the second limiting pin 312 is inserted into the second limiting hole 322 to keep the support frame 3 in a folded state; specifically, in order to ensure that the position of the second limiting hole 322 corresponds to the second limiting pin 312 after the support frame 3 is folded, a limiting plate 323 is also provided on the hinge part 32. The second limiting hole 322 is set on the limiting plate 323. During assembly, the limiting plate 323 can be welded to the hinge part 32 when the support frame 3 is in a folded state, so as to adjust the position of the second limiting hole 322 in real time to align with the second limiting pin 312.

[0030] The cam 132 is provided with a screw thread 132 on the top of the cam 132 so that the cam 132 can be screwed onto the top of the cam 132 to prevent the cam 132 from sliding.

[0031] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
