Description

Technical Field

[0001] The utility model relates to the technical field of logistics freight boxes, in particular to a logistics freight box with an anti-bumping structure. Background Art

[0002] Freight transportation is one of the main modes of modern transportation and one of the two basic modes of land freight transportation. It occupies an important position in the entire transportation field and plays an increasingly important role. Freight transportation is less affected by climate and natural conditions, and has large transportation capacity and single-vehicle loading capacity, so it has advantages in regularity and low cost of transportation.

[0003] After searching the publication (announcement) number: CN217199922U, a box structure for freight transportation is disclosed, including a freight box, a rear door is arranged on one side of the freight box, a handle is fixedly connected to the outside of the rear door, an anti-fall mechanism is arranged on the side parallel to the handle, a protective net is fixedly installed inside the anti-fall mechanism, a side door is arranged on the side perpendicular to the rear door, the side door includes a side door handle, a folding canopy mechanism is arranged above the side door handle, a support column is fixedly connected to one side of the protective net, a matching piece is welded to the bottom of the support column, a support foot base is fixedly connected below the matching piece, and an inclined groove is opened on the inner surface of the support foot base. The box structure for freight transportation, by arranging an anti-fall mechanism on the rear door of the freight box, can block one side of the goods through the protective net to prevent the goods from tipping over in the direction of the rear door due to the bumps of the road during transportation, thereby achieving a protective effect on the goods.

[0004] Although the above solution avoids the goods from falling toward the rear door due to road bumps, it is difficult to ensure that the topmost goods are in contact with the top wall of the cargo compartment when the goods are stacked. This makes it impossible to apply downward pressure and tightening force to all the goods, causing the goods that are not in contact with the sheet material to hit the top wall of the cargo compartment during bumps. For this reason, we propose a logistics freight box with an anti-bumping structure. Utility Model Content

[0005] The main purpose of the utility model is to provide a logistics freight box with an anti-bumping structure. By setting a binding unit and a pressure contact unit, it solves the problem that it is difficult to ensure that the topmost goods are in contact with the top wall of the cargo compartment when the goods are stacked, which makes it impossible to apply downward pressure and tightening force to all the goods, resulting in the goods that are not in contact with the sheet material hitting the top wall of the cargo box during bumps.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A logistics freight box with an anti-bumping structure comprises a box unit and two sets of adjustment units arranged in the box unit, a restraining unit and a clamping unit arranged in the adjustment unit, and a pressure contact unit arranged in the box unit;

[0008] The binding unit comprises a reel movably arranged in one set of adjustment units, an elastic binding belt installed on the side wall of the reel, a day plate installed in another set of adjustment units, and a fixing member arranged at the adjacent end of the elastic binding belt and the day plate;

[0009] The pressure touch unit includes a mounting groove provided in the center of the top wall of the box unit, a screw rod movably provided in the mounting groove, two sections of threads with opposite rotation directions provided on the screw rod, a moving part installed on the screw rod, a driving motor installed at the input end of the screw rod, a pressure plate provided in the box unit, and a movable connecting part provided between the moving part and the pressure plate.

[0010] Preferably, the box unit includes a cargo compartment, a box door opened on a side wall of the cargo compartment, and an opening and closing handle installed on the side wall of the box door.

[0011] Preferably, the adjustment unit includes a movable groove opened on the inner side wall of the cargo compartment, a sliding groove opened on the bottom wall of the movable groove, a locking groove opened on the side wall of the movable groove, a movable seat movably arranged in the movable groove, and a sliding wheel installed on the bottom of the movable seat and in contact with the sliding groove.

[0012] Preferably, the fixing member comprises a Velcro surface A and a Velcro surface B installed on the side wall of the elastic binding band, and the Velcro surface B is located on the side of the Velcro surface A away from the winding shaft.

[0013] Preferably, the movable connecting member includes an upper connecting seat installed at the bottom of the moving member, a lower connecting seat installed at the top of the pressure plate, and a connecting plate with one end movably connected to the upper connecting seat and the other end movably connected to the lower connecting seat.

[0014] Preferably, the pressure contact unit further comprises an automatically inflating and deflation air bag installed at the bottom of the pressure plate.

[0015] Preferably, the engaging unit includes a moving through hole opened in the opposite side wall of the moving seat, a engaging column movably passing through and arranged in the moving through hole, a compression plate installed at one end of the engaging column located inside the moving seat, and a spring installed between the two compression plates.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, by means of the provided binding unit and the pressure contact unit, after the goods are stacked against the driver's side, the two compression plates are pressed to make them close to each other, and the spring is compressed, so that the engaging column is separated from the engaging groove, and the movable seat can be pulled to move in the movable groove. When the movable seat moves to the boundary of the goods stacking, the force applied to the compression plate is removed, and the engaging column is re-engaged with the engaging groove under the elastic force of the spring; at this time, the elastic binding belt is pulled through the day plate, and the Velcro A surface is bonded to the Velcro B surface, so that the side binding and fixation of the goods can be realized. To prevent the cargo from sliding off the side when passing through bumpy roads; when the cargo is partially restrained, the drive motor drives the lead screw to rotate. Since the lead screw has threads with opposite rotation directions at both ends, the two moving parts can move along the lead screw in the direction of approaching or moving away from each other, thereby driving the pressure plate to move up and down through the movable connecting part. When the pressure plate collides with the top of all the cargo, the automatic inflating and deflation airbag automatically inflates and deflates to fill the gap between the pressure plate and the top of the cargo, thereby realizing the top restraint of the cargo and ensuring that the cargo will not hit the top wall of the cargo box when passing through bumpy roads.
