Description

Logistics box lid fixing device

The present invention relates to a box lid fixing device for a logistics box. The fixing device is arranged on the opening side of the box lid of the logistics box, and can support and fix the box lid to maintain it in an open state when the box lid is opened.

During operation, the lid of existing logistics boxes rotates and opens. Without additional support, the lid naturally falls down under the influence of gravity, obstructing the opening and hindering the loading and unloading of goods, which increases the difficulty and processing time. Users must constantly reopen the lid to maintain the opening, which is not only inconvenient but also affects the continuity and efficiency of the operation.

To solve this problem, some existing technologies have proposed a solution of rotating the box lid completely to the side. That is, the box lid is completely rotated to the side of the logistics box and placed in the logistics box working compartment so that the box lid does not block the opening of the logistics box. However, this solution also has inconveniences when it is necessary to complete the operation and close the box lid. Because the box lid has been rotated to the side, if the closing operation is to be performed, the logistics box must first be pulled out of the working area to provide sufficient space for the box lid to rotate and close. This adds unnecessary steps to the operation process, especially when the logistics box is already loaded with goods. The operation of pulling out and re-placing the logistics box is more difficult, further reducing the operation efficiency.

Therefore, the existing technology still has the disadvantages of being cumbersome and inconvenient in keeping the box lid open and closing it after the operation is completed. A simpler and more effective solution is urgently needed.

The present invention provides a practical fixing device that can solve the problem in the prior art that the box lid cannot be effectively fixed, improve the convenience of use of the logistics box, and is suitable for keeping the box lid open for various types of logistics boxes.

The present invention relates to a logistics box lid securing device, designed to be mounted on the opening side of a logistics box lid. The device comprises a bracket, a baffle, a rod, and a sleeve. The baffle is mounted on the bracket and corresponds to the opening side of the lid. The rod is mounted transversely on the baffle or bracket and is higher than the baffle. The sleeve is movably mounted on the rod, allowing it to move at least longitudinally on the rod.

When the lid is opened toward the opening side, external force causes the edge of the lid to push against the sleeve, causing the sleeve to move upward on the rod. When the sleeve is higher than the edge of the lid, the edge of the lid passes over the sleeve and is stopped by the stopper on the outer side of the lid, causing the lid to lean against the stopper at an angle. The sleeve then automatically drops down and abuts against the inner side of the lid. In this way, the lid is clamped between the sleeve and the stopper, achieving the purpose of maintaining the lid open and facilitating the loading and unloading of goods in the logistics box.

In a preferred embodiment, one end of the sleeve is fixed to a coupling member, and the coupling member is fixed to the baffle or the bracket.

In a preferred embodiment, the coupling member is provided with an adjustment hole, which is a longitudinally long hole. The coupling member is fixed to the blocking portion or the bracket by a screw passing through the adjustment hole.

In a preferred embodiment, the sleeve has a through hole therein, the diameter of the through hole is larger than the sleeve rod, so that the sleeve rod has a movable space in the through hole.

In a preferred embodiment, the end of the sleeve rod has a hook portion.

The logistics box lid fixing device of the present invention can also be used with two logistics boxes together. The fixing device is used to be installed between the two logistics boxes and corresponds to the opening side of the box lid of the logistics boxes. It includes a bracket, a baffle, two sleeves, and two sleeves. The baffle is installed on the bracket and corresponds to the opening side of the box lid. The sleeves are symmetrically and laterally arranged on two corresponding sides of the baffle or the bracket, and the sleeves are higher than the baffle. The sleeves are movably mounted on the sleeves, allowing them to move at least longitudinally on the sleeves.

Thus, these fixtures can be arranged horizontally in multiple groups, with a logistics box placed between every two adjacent fixtures. Multiple sets of these fixtures can be arranged in a continuous manner to accommodate multiple logistics boxes. This configuration offers the highest efficiency, maximizing the placement and operation of multiple logistics boxes within a limited space, ensuring that the lid of each logistics box remains stably open. This makes it suitable for multi-box operations in logistics warehouses or automated warehousing systems.

In addition, since the stoppers stop at the outer sides of the box covers, after the loading and unloading operations, the box covers can be covered back on the logistics box without interference, and there is no need to pull out the logistics boxes.

In a preferred embodiment, one end portion of the sleeve rods is fixed to two coupling members, and the coupling members are symmetrically fixed to two corresponding sides of the baffle or the bracket.

In a preferred embodiment, the coupling members are each provided with an adjustment hole, which is a longitudinally long hole. The coupling members are fixed to the corresponding two sides of the blocking portion or the bracket by at least two screws passing through the adjustment holes.

In a preferred embodiment, each of the sleeves has a through hole therein, and the diameter of the through hole is larger than that of the sleeve rods, so that the sleeve rods have movable space in the through hole.

In a preferred embodiment, the ends of the sleeve rods have a hook portion.

Please refer to Figure 1, which is a schematic perspective view of a first embodiment of a fixing device 10 of the present invention and a logistics box 20. As shown in the figure, the fixing device 10 includes a bracket 30, a stop 40, a set of rods 50, and a sleeve 60. The fixing device 10 is used to be installed on the opening side of a logistics box 20. The opening side refers to the specific direction in which the lid 21 of the logistics box 20 opens, which generally corresponds to the opening edge of the logistics box 20. The lid 21 is typically hinged to the opening edge of the logistics box 20 corresponding to the opening side, so that the lid 21 can be operated toward the opening side when opened. Typically, the logistics box 20 has one or two opening sides, depending on the number of box lids 21 provided on the logistics box 20. For example, the logistics box 20 is provided with two opposite box lids 21, and the two opening sides are located on opposite sides of the opening direction of the two box lids 21.

Please refer to Figure 2, which is a schematic exploded perspective view of a first embodiment of the fixing device 10 of the present invention. As shown in the figure, bracket 30 is mounted on the ground to support the fixing device 10. More specifically, the bottom of bracket 30 is secured to the ground with screws to prevent it from shaking. In other embodiments, other methods of securing the fixing device 10 may include welding, pressure with a heavy object, ground embedding, clamping or latching, suction cups, or adhesives, but this embodiment is not limited to these methods.

The stopper 40 is mounted on the bracket 30. More specifically, one side of the stopper 40 is welded to the bracket 30. In other embodiments, the fixing method may include bolts, clamps or latches, suction cups, or adhesives, but this embodiment is not limited thereto. The stopper 40 is higher than the logistics box 20 and has a predetermined area to prevent the lid 21 from being opened when the logistics box 20 is opened.

The sleeve rod 50 is disposed transversely on the stop 40 and is higher than the stop 40. More specifically, one end 51 of the sleeve rod 50 is screwed to a coupling 52, which is also screwed to the stop 40. In other embodiments, the fixing method may include welding, clamping or latching, suction cup or adhesive fixing, etc., but this embodiment is not limited to these. In addition, the coupling 52 may also be fixed to the bracket 30. As long as the sleeve rod 50 can be disposed transversely and higher than the stop 40, it falls within the scope of this embodiment.

Next, the coupling member 52 can be designed to be height-adjustable by providing an adjustment hole 521 on the coupling member 52. The adjustment hole 521 is a longitudinally elongated hole. When the coupling member 52 is secured to the stopper 40 or bracket 30 via a screw, loosening the screw allows the screw to move freely within the adjustment hole 521, allowing the screw to slide within a certain range, thereby adjusting the height of the coupling member 52 on the stopper 40 or bracket 30.

Regarding the sleeve 60, it is movably mounted on the sleeve rod 50. More specifically, the sleeve 60 has a through-hole 61 therein. The diameter of the through-hole 61 is larger than that of the sleeve rod 50, allowing the sleeve rod 50 to move within the through-hole 61. Therefore, the sleeve 60 can move on the sleeve rod 50, particularly longitudinally. As described above, the distal end of the sleeve rod 50 has an upwardly extending hook 53. When the sleeve 60 is mounted on the sleeve rod 50, the coupling member 52 and the hook 53 stop the sleeve 60 at both axial ends of the sleeve rod 50, preventing the sleeve 60 from falling off the sleeve rod 50.

Please refer to Figures 3 and 4. Figure 3 is a side view schematically illustrating the first embodiment of the fixing device 10 of the present invention, opening the lid 21. Figure 4 is a side view schematically illustrating the first embodiment of the fixing device 10 of the present invention, securing the lid 21. (Since both fixing devices 10 operate in the same manner, only one side will be described below.) As shown in the figures, in the first embodiment, the two fixing devices 10 are positioned on the two open sides of the logistics box 20. When the lid 21 is opened toward the open side, the edge of the lid 21 preferentially abuts the outer side of the sleeve 60. As the thrust is continued, the edge of the lid 21 pushes against the sleeve 60, causing the sleeve 60 to move upward on the sleeve rod 50. When the sleeve 60 moves upward to a position above the edge of the lid 21, the edge of the lid 21 passes over the sleeve 60 and eventually stops against the outer side of the lid 21, causing the lid 21 to rest at an angle against the stop 40. The sleeve 60 then automatically drops (in practice, the sleeve 60 should have a predetermined weight so that, when not affected by external forces, it will automatically drop under the influence of gravity) to rest against the inner side of the lid 21. By clamping the lid 21 between the sleeve 60 and the stop 40, the lid 21 is held open. This keeps the lid 21 open at a certain angle, facilitating loading and unloading of goods within the logistics box 20.

Based on the above, the outer side of the sleeve 60 can be a circular arc surface 62, so that the edge of the box cover 21 can more easily pass over the circular arc surface 62 without getting stuck.

Please refer to Figure 5, which is a schematic exploded perspective view of a second embodiment of the fixing device 10 of the present invention. As shown in the figure, the fixing device 10 includes a bracket 30, a block 40, two rods 50, and two sleeves 60. The second embodiment differs from the first embodiment in that the second embodiment includes two rods 50 and two sleeves 60, which are symmetrically arranged on opposite sides of the block 40. In short, the second embodiment is based on the first embodiment, with another rod 50 and another sleeve 60 symmetrically arranged on the other side of the block 40 of the first embodiment. The remaining technical details are the same as the first embodiment and will not be repeated here.

Please refer to Figure 6, which is a schematic perspective view of a second embodiment of the fixing device 10 of the present invention, used to fix a box lid 21. As shown in the figure, in this second embodiment, multiple sets of fixing devices 10 can be arranged horizontally, with one logistics box 20 positioned between each pair of adjacent fixing devices 10 (equivalent to one fixing device 10 positioned between two adjacent logistics boxes 20). For example, if there are three fixing devices 10, two logistics boxes 20 can be accommodated. After opening, the lid 21 of each logistics box 20 can be secured between the sleeve 60 and the stop 40 on its corresponding opening side, thereby maintaining the lids 21 of multiple logistics boxes 20 open. Similarly, multiple sets of fixing devices 10 can be arranged in series to accommodate multiple logistics boxes 20. This configuration has the highest efficiency and can place and operate multiple logistics boxes 20 to the maximum extent within a limited space, ensuring that the box cover 21 of each logistics box 20 can remain stably open. It is suitable for multi-box operations in logistics warehouses or automated warehousing systems.

In addition to the above two embodiments, the fixing device 10 can also be used alone, which is suitable for a logistics box 20 with only a single box cover 21. Alternatively, a logistics box 20 that only needs to fix a single side of the box cover 21 is used. Both belong to the scope of the present invention.

In summary, the logistics box lid securing device provided by the present invention offers the following advantages compared to other conventional technologies: 1. Simple structure, low cost, and easy installation and maintenance; 2. Excellent stability and reliability, effectively securing the lid; 3. Convenient to use, requiring only simple operations to secure and open the lid; 4. The lid can be tilted at various angles after opening, facilitating the placement and retrieval of goods; 5. Multiple configurations are available to suit different application scenarios, suitable for single or multiple logistics boxes, offering flexibility and efficiency; 6. The adjustable rod and its fastening element, with adjustment holes for multiple fixing points, allows for adjustable rod height to accommodate logistics boxes of varying sizes and operating requirements.
