Description

Technical Field

[0001] This utility model belongs to the field of enclosed box technology, and more specifically, it relates to an enclosed box locking mechanism. Background Technology

[0002] Traditional palletized crates are mostly one-piece designs with a fixed volume, unable to adapt to different material sizes. Furthermore, they occupy a significant amount of space when not in use, making them inconvenient to store. Therefore, with technological advancements, traditional one-piece palletized crates are gradually being phased out. Currently, most palletized crates on the market are foldable, consisting mainly of a pallet, body, and lid, offering advantages such as easy storage and smaller footprint.

[0003] Based on the above, the inventors have discovered the following problems: In current use, the enclosure panels and the base are mostly fixed by mechanical means such as bolts. Although this connection method can ensure the stability of the enclosure panels during transportation, it brings many inconveniences to the replacement and maintenance of the enclosure panels. Once the enclosure panels need to be replaced due to long-term use or accidental damage, the staff needs to use special tools to carry out tedious disassembly and installation work, which is not only time-consuming and labor-intensive, but may also cause additional damage to the base due to improper operation. In addition, frequent disassembly and installation may also accelerate the wear of the connection between the enclosure panels and the base, further shortening the service life of the enclosure panel box.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a locking mechanism for the enclosure box in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a locking mechanism for enclosed boxes, which solves the problem that current enclosed boxes are installed by means of bolts and other fixing methods, and that replacement and maintenance are time-consuming and labor-intensive.

[0006] The purpose and effect of this utility model's locking mechanism for a panel box are achieved through the following specific technical means:

[0007] A locking mechanism for a pallet box includes a base, a slot at the top of the base, a baffle inside the slot, a chamber inside the slot, a set of trapezoidal blocks I inside the chamber, a second trapezoidal block II in the middle of the set of trapezoidal blocks I, a movable block at the top of the second trapezoidal block II, the movable block being vertically limited and installed inside the chamber, an arc-shaped support plate at the top of the movable block, an L-shaped rod on one side of the set of trapezoidal blocks I, an arc-shaped clamping block on one side of the L-shaped rod, and an arc-shaped locking block at the bottom of the baffle.

[0008] Furthermore, the arc-shaped card block and the arc-shaped clamping block are matched.

[0009] Furthermore, a spring is provided on one side of one of the trapezoidal blocks, and the other end of the spring is connected to the inner wall of the cavity.

[0010] Furthermore, a second spring is provided at the bottom of the trapezoidal block two, and the other end of the second spring is connected to the bottom of the chamber.

[0011] Furthermore, the interior of the chamber is provided with a partition plate, and the partition plate has movable grooves on both sides, and the L-shaped rod is rotatably installed in the movable groove.

[0012] Furthermore, a through groove is provided on one side of the base, and the through groove is connected to the cavity.

[0013] Furthermore, a toggle block is provided in the through groove, and the toggle block is connected to the moving block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By coordinating trapezoidal block one, trapezoidal block two, arc-shaped support plate, L-shaped rod, arc-shaped clamping block, arc-shaped locking block, moving block, partition plate, movable groove, through groove, and actuating block, the baffle to be installed is snapped into the slot. Under the action of gravity, the arc-shaped locking block is pressed down and placed on the arc-shaped support plate. The moving block is vertically limited and installed in the cavity. When the moving block moves down, trapezoidal block two moves down, pushing trapezoidal blocks one on both sides to move to the sides, squeezing the L-shaped rod to rotate, so that the arc-shaped clamping block snaps into the arc-shaped locking block, achieving the effect of fixed installation. Conversely, when it is necessary to replace the maintenance baffle, it is pulled up, and then the actuating block is moved up. Under the action of spring one and spring two, trapezoidal blocks one and two return to their original positions, achieving the effect of loosening, which facilitates quick disassembly and improves work efficiency.
