Description

Technical Field

[0001] This utility model belongs to the field of packaging box connection technology, and specifically relates to a packaging box lifting structure and packaging box. Background Technology

[0002] In modern logistics and transportation systems, standardized packaging boxes, as core components of cargo carriers, play a vital protective role in land, sea, and multimodal transport due to their structural stability and impact resistance. However, the efficiency bottlenecks exposed by traditional operating methods are becoming increasingly apparent in loading and unloading operations. The currently prevalent single-box, separate lifting process requires independent attachment of lifting equipment for each box: operators must repeatedly wrap the slings, secure them with clips, or use electromagnetic chucks for positioning. After each lifting operation, the connection devices must be completely disconnected before the next box can be handled. This discrete operational process leads to a severe imbalance between loading and unloading efficiency and the turnover rate of transport vehicles.

[0003] More notably, frequent mechanical disassembly and assembly accelerates the wear cycle of spreader components. Taking the common C-type hook as an example, the fatigue life of its hinged part will be shortened by 40% in intensive operation environments, directly increasing equipment maintenance costs. In addition, the uncontrollable risks of manual intervention persist. Accident statistics from a port in 2022 showed that 83% of cargo damage incidents caused by accidental spreader detachment occurred during the transition between lifting tools. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting structure for a packaging box and a packaging box in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting structure for a packaging box includes a lifting lug mechanism and a lifting mechanism, which can be connected to each other.

[0007] The lifting lug mechanism includes a lifting lug base and a lifting lug. The lifting lug is slidably fixed on the lifting lug base and can slide up and down along the lifting lug base.

[0008] The lifting mechanism is equipped with a slot that matches the lifting lug, and the lifting lug can be fixed in the slot.

[0009] Furthermore, the base of the lifting lug is provided with a protrusion, and the inner side of the protrusion is provided with a closed groove, with one end of the lifting lug set in the groove.

[0010] Furthermore, the lifting lug has a U-shaped structure, and the open end of the lifting lug is fitted inside the closed slide groove by a fastening mechanism; the top of the protrusion is provided with a shaft clip for locking the lifting lug.

[0011] Furthermore, the fastening mechanism includes a hex socket head cap screw, a type I hex nut, and a cotter pin. The type I hex nut is located inside the U-shape of the lifting lug, and the hex socket head cap screw passes through the lifting lug and the type I hex nut and is then fixed by the cotter pin.

[0012] Furthermore, the base of the lifting lug is provided with threaded holes for fixing.

[0013] Furthermore, the lifting mechanism includes a lifting block, a base plate, and a U-shaped block. Both the lifting block and the U-shaped block are mounted on the base plate, and a slot is formed between the lifting block and the U-shaped block.

[0015] Furthermore, the lifting eye cover is connected to the lifting block via a cover plate pivot, which is fixed by an internal hexagon countersunk screw.

[0016] Furthermore, the substrate is provided with bolt holes for fixing.

[0017] A packaging box includes a lifting structure for the packaging box, wherein the lifting lug mechanism and the lifting mechanism of the lifting structure are respectively installed on two packaging boxes to be connected.

[0018] Compared with the prior art, the present invention has the following technical effects:

[0019] The quick-fitting mechanism of the interlocking lifting structure of this utility model enables the simultaneous fixing of multiple standard boxes in a single lifting operation, significantly improving loading and unloading efficiency.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1: This utility model provides a lifting structure for a packaging box, including a lifting lug mechanism and a lifting mechanism, which can be connected to each other.

[0032] The lifting lug mechanism includes a lifting lug base 1 and a lifting lug 2. The lifting lug 2 is slidably fixed on the lifting lug base 1 and can slide up and down along the lifting lug base 1.

[0033] The lifting mechanism is equipped with a slot that matches the lifting lug 2, and the lifting lug 2 can be fixed in the slot.

[0034] The lifting lug 2 forms a vertical sliding pair with the lifting lug base 1 through a closed sliding groove, allowing the lifting lug to adaptively adjust its height within a range of ±150mm. The shaft clip 7 automatically locks when the lifting lug is raised to its limit position to prevent accidental slippage.

[0035] The U-shaped block 13 of the lifting mechanism and the lifting block 8 form a standard slot. When the lifting device descends, the U-shaped opening end of the lifting lug 2 is precisely inserted into the slot, and the fit gap is controlled within 0.5-1mm.

[0036] The lifting ring cover plate 9 is closed by rotating through the cover plate pivot 10, forming a closed force-bearing ring;

[0037] The internal hex socket screw 3 and the cotter pin 6 form an anti-loosening structure to ensure a rigid connection between the lifting lug and the slot.

[0038] During hoisting, the U-shaped structure of the lifting lug 2 converts the concentrated load into surface contact stress, which is distributed to the eight fixing points of the base plate bolt holes through the chromium-molybdenum steel base plate of the connecting block 8, reducing the single-point pressure from 120MPa to 75MPa.

[0039] The closed-loop slide groove with hard chrome-plated inner wall forms a low-resistance motion pair with the sliding surface of the lifting lug, reducing energy loss during adjustment.

[0040] Multi-container simultaneous hoisting: 4-6 standard containers can be fixed in a single operation, which significantly improves loading and unloading efficiency compared to traditional single-container hoisting.

[0041] Rapid alignment: Laser positioning and slot guide design shorten the positioning time of a single box and increase the effective working time of the equipment.

[0042] The shaft 7 and the cotter pin 6 form a double safety mechanism.

[0043] The internal hex countersunk screw 12 enables tool-free replacement of the eyelet cover 9, reducing maintenance time for individual components.

[0044] Example 2: This utility model provides a packaging box, including the lifting structure of the packaging box, wherein the lifting lug mechanism and the lifting mechanism of the lifting structure are respectively installed on the two packaging boxes to be connected.

[0045] The lifting lug mechanism and the linkage mechanism are installed on the top and bottom of adjacent boxes respectively, forming a cascade structure of "upper lifting lug - lower slot".

[0046] The base plate bolt holes support rapid docking with different vehicles such as ship lashing bridges and railway flatcar locks.

[0047] The sliding adjustment function of lifting lug 2 compensates for the stacking height tolerance of the boxes, reducing the overall center of gravity shift of the hoisting system.

[0048] The interlocking structure improves the utilization rate of vehicle space.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
