Description

Technical Field

[0001] The utility model relates to the technical field of grape transportation boxes, in particular to a grape transportation box with a fresh-keeping function. Background Art

[0002] As a kind of perishable fruit sensitive to transportation environment, fresh-keeping transportation of grapes after picking has always been a difficult problem in the industry. Traditional transportation methods mostly use ordinary foam boxes or plastic baskets supplemented by ice bags for cooling, but generally have problems such as short heat preservation duration, large temperature fluctuation, internal condensation, stacking extrusion damage and inconvenient handling. Especially in long-distance transportation, changes in external ambient temperature can easily lead to an increase in the temperature inside the box, accelerating the decay of grapes; meanwhile, condensed water from ice bags cannot be discharged and easily contaminates grapes, and rough handling easily causes fruit shedding or damage. Although there are some heat preservation box designs in the prior art, most of them have simple structures and lack the cooperative design of multi-layer heat preservation and structural support, and cannot simultaneously meet the requirements of long-term fresh-keeping, compression resistance protection and convenient handling. Therefore, we propose a grape transportation box with fresh-keeping function. Summary of the Utility Model

[0003] The utility model mainly aims to solve the technical problems existing in the above-mentioned prior art, and provides a grape transportation box with a fresh-keeping function.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: a grape transportation box with a fresh-keeping function comprises a supporting box, wherein the supporting box is a rectangular frame, a detachable supporting plate is arranged at a position below the middle inside the supporting box, a plurality of hexagonal through grooves are equally spaced on the upper side of the supporting plate, a plurality of mounting cavities are formed on the upper side of the supporting plate, heat-insulating foam is clamped inside each mounting cavity, four pieces of heat-insulating foam form a "loop" shape to wrap the central position of the supporting plate, a protective shell is arranged outside the supporting box, the protective shell is a rectangular box with an opening at the lower end, a guide groove is formed above the protective shell, a detachable handle is arranged on the upper side of the supporting box, and the handle upwardly penetrates through the guide groove and extends to the upper part of the protective shell.

[0005] Preferably, two mounting grooves are formed on the side surface of the supporting box, and extension rods are fixedly installed at positions corresponding to the mounting grooves on the bottom side of the supporting plate.

[0006] Preferably, two symmetrically distributed gripping handles are fixedly installed on the upper side of the supporting plate, and the gripping handles are inverted "U"-shaped blocks.

[0007] Preferably, a fixed sliding block is arranged on the bottom side of the handle, the sliding block is slidably installed inside the mounting groove, a limit groove is formed on the wall surface of the supporting box corresponding to the side surface of the mounting groove, and a limit block adapted to the limit groove is formed on the side surface of the sliding block.

[0008] Preferably, guide holes are provided at four corners of the upper side of the supporting box, a fixed connecting rod is arranged between the sliding block and the handle, and a guide column extending into the guide hole is fixedly installed on the bottom side of the connecting rod.

[0009] Preferably, grooves are formed on both sides of the supporting box, and ventilation holes are equally spaced on the outer side of the supporting box. Beneficial Effects

[0010] The utility model provides a grape transport box with a fresh-keeping function. It has the following beneficial effects: (1) The grape transport box with a fresh-keeping function adopts a multi-layer nested design of a support plate, thermal insulation foam and a protective shell, which significantly improves the thermal insulation and fresh-keeping performance and compressive stability of the box body. Specifically, the support plate is centrally erected at a position lower than the middle part in the supporting box, and a plurality of hexagonal through grooves formed in the upper part of the support plate not only reduce the weight of the plate, but also facilitate uniform circulation of cold air from bottom to top, avoiding excessive local temperature; a plurality of thermal insulation foam blocks clamped on the support plate jointly enclose a "back"-shaped inner liner, which tightly wraps grapes to form a first thermal insulation barrier, effectively blocks heat exchange and delays the cold loss of ice bags. The protective shell is sleeved outside the supporting box to form a second thermal insulation layer, and its closed structure further enhances the overall heat insulation effect. The dual thermal insulation design works synergistically to greatly extend the maintenance time of the low-temperature environment, ensuring that grapes are in a stable and suitable low-temperature and high-humidity environment during transportation. At the same time, the rigid materials of the support plate and the protective shell jointly enhance the compressive strength of the box body, preventing grape breakage caused by extrusion of the upper box body during stacking, and solving the problems of easy deformation and short thermal insulation duration of traditional packaging.

[0011] (2) The grape transport box with a fresh-keeping function optimizes the convenience and safety of handling and loading / unloading operations through the linkage structure of gripping handles, a handle and a limiting groove. Inverted U-shaped gripping handles are symmetrically and fixedly arranged on the support plate, which is convenient for a user to manually lift the support plate and the grapes thereon, realizing rapid overall unloading and avoiding the cumbersome operation and damage risk of picking grapes one by one. The detachable handle design above the supporting box, combined with the guide groove at the top of the protective shell, makes the lifting action natural and smooth without derailment; the sliding block at the bottom of the handle is embedded into the mounting groove on the side wall of the supporting box, and the clamping fit between the side limiting block and the limiting groove ensures that the force is directly transmitted to the whole supporting box when the handle is lifted, avoiding tripping or deflection. The guide column at the bottom of the connecting rod is inserted into the guide holes at the four corners of the supporting box, which further enhances the vertical stability during lifting and prevents the box body from shaking. In addition, the grooves on both sides of the supporting box provide secondary grip points, and the ventilation holes evenly distributed on the side satisfy both the requirements of ventilation and condensation water volatilization, avoiding moisture accumulation that damages grapes. The whole human-computer interaction design significantly reduces labor intensity, improves operation efficiency, and ensures safety and stability during transportation. Description of Drawings
