Description

Zero-dismantling turnover box

Technical Field

The invention relates to the field of cargo loading and turnover transportation, in particular to a turnover box which is free of disassembly and zero and can be quickly disassembled, combined, recycled and reassembled for use.

Background

The existing liquid transportation turnover box is a box body composed of a bottom plate with a bottom beam, side vertical plates around and a cover plate on the upper part, corners of each adjacent box plate of the box body are matched and fixed with a plurality of connecting plate connecting pieces through claw nuts which are nailed into the box body, and fixed angles of the box corner positions are composed of three screws. Because in the transportation process of transporting goods and the turnover box itself, the turnover box needs to be disassembled and assembled, and the connecting pieces, the fixed angles, the screws and the like on the existing turnover box need to be disassembled. Under the very big circumstances of dismouting volume, need rely on electric spanner to dismantle the bolt one by one and just can dismantle turnover case board totally when dismantling generally, the part that the turnover case was dismantled all needs to keep alone, often takes place the part and loses, the condition on the equipment, when the staff's of kludge work load increases, also greatly draw work efficiency down, increased use cost.

Because liquid package is different with solid package, liquid does not have fixed shape and can rise all around, makes four curb plates atress all, and in car and boat transportation, because pressure and inertial action, the cardboard of front and back easily inwards emptys, very easily produces great clearance between each cardboard, presss from both sides the packing bag often, leads to leaking of liquid such as fruit juice, jam, causes the loss.

Besides the problem that gaps between the box plates are used for clamping and breaking the inner bags of the packaging bags, the four-jaw nuts adopted by the existing turnover box are nailed into the connecting holes and are connected with the connecting holes through bolts to fix the corner fixing connecting pieces, the four-jaw nuts are very easy to loose and fall off after being repeatedly disassembled and assembled, and when liquid products are transported, the packaging bags in the turnover box are often broken by the fallen four-jaw nuts, so that the losses such as leakage pollution and the like of the liquid products are caused.

Disclosure of Invention

The invention adopts a zero disassembly design, does not need special personnel to store parts, realizes quick and convenient disassembly and assembly, ensures more firm connection among all assemblies, and avoids economic loss caused by part falling or box board inclination.

In order to achieve the above purpose, the invention provides a zero-dismantling turnover box, which is a box body composed of six box boards, wherein a connecting piece is arranged on an edge of the box body, and a fixed angle is arranged at a vertex angle, and is characterized in that: the connecting piece consists of an L-shaped lock hook and a lock catch;

the L-shaped lock hook corner covers the edge of the box body, two ends of the L-shaped lock hook extend to completely cover the joint between the two box boards, one end of the L-shaped lock hook is fixed on the box board, and the end part of the other end is outwards bent to form a hook head and the lock catch arranged on the board surface of the box board where the end is located.

Preferably, the connecting piece is connected and fixed on the edge of the box body through bolts and inner and outer tooth nuts screwed into the box plates.

In a preferred mode, a reinforcing rib extending to the fixed end of the L-shaped lock hook along the long side direction of the L-shaped lock hook is arranged below the hook opening of the hook head of the L-shaped lock hook.

Preferably, the end of the hook head is parallel to the box body or the end of the hook head is inclined to the side of the surface of the box body, and the inclination angle is preferably 3-5 degrees.

Under the preferred mode, the boxboard include the bottom plate, with four curb plates and the apron of bottom plate perpendicular setting, four curb plates divide into two opposite first curb plates of pairwise and two second curb plates.

In the preferred mode, two sides of the inner plate surface of the first side plate are provided with L-shaped clamping grooves perpendicular to the bottom plate, and the second side plates are arranged in the L-shaped clamping grooves on the opposite sides of the two first side plates.

In a preferred mode, the outer sides of the four sides of the cover plate and the bottom plate are covered with the L-shaped lock hooks, and the outer plate surfaces of the two first side plates and the two second side plates are provided with the lock catches corresponding to the L-shaped lock hooks on the cover plate and the bottom plate; the second side plate outer plate surface is provided with the lock catch matched with the L-shaped lock hook arranged on the first side plate outer plate surface, or the first side plate outer plate surface is provided with the lock catch matched with the L-shaped lock hook arranged on the second side plate outer plate surface.

Under the preferred mode, after the box body is disassembled, the stacking sequence of each box plate is as follows from bottom to top in sequence: the bottom plate, one second side plate, two first side plates, the other second side plate and the cover plate.

In the preferred mode, after the box body is disassembled, two first side plates are stacked back to back, the L-shaped lock hooks of the two first side plates are staggered with the L-shaped lock hooks on the cover plate and the bottom plate, and the second side plates are wrapped in the L-shaped lock hooks.

Preferably, after the connecting piece is connected, a locating pin or a nylon tightening locking bar is inserted into a locking hole at the tail part of the lock catch to lock.

The invention has the advantages that:

1. the fastening mode of the lock catch fundamentally realizes the minimization of the gap of the box plate.

In the invention, the length of the L-shaped lock hook with the hook head end is longer than the distance from the connecting gap of the two box boards to the edge, and the tensioning effect of the lock catch matched with the L-shaped lock hook is remarkable. According to the invention, the L-shaped clamping groove of the first side plate clamps the second side plate and plays a role in limiting together with the connecting piece, so that the box plates are prevented from tilting in the process of transporting liquid products by a vehicle or a ship, the box plates are tightly connected, and the risk of clamping and breaking packaging bags is avoided. After the L-shaped lock hook with the reinforcing rib is connected with the lock ring on the lock buckle in a tensioning manner, a lock pin (or a tensioning lock bar) is inserted between the box boards, so that firm and rigid connection is completed. Saturated brine tests filled into the tank (about 1.5 tons) demonstrated that there was no visible gap between the tank plates. The above effects are not achieved by other fastening means.

The fixed end of the connecting piece is connected with the inner and outer tooth nuts embedded in the box body through bolts, the inner and outer tooth nuts are countersunk nuts, and are screwed into the seamless allowance in the box plate, so that the connecting piece is firm and reliable, and the connecting piece and the bolts matched with the connecting piece cannot fall off even if the connecting piece and the bolts are repeatedly disassembled. The problems that the 4-claw nails and the box plate holes used in the existing products have allowance, the 4 claws are not firm, the 4-claw nails are easy to drop after repeated disassembly and assembly, the aseptic bags can be punctured by the dropped 4-claw nails, and loss is caused by juice leakage are solved.

The connecting fastener consists of an inner tooth nut, an outer tooth nut, a bolt, an L-shaped reinforcing rib lock hook and a lock catch (comprising a lock body and a lock ring).

Compared with the four-jaw nut adopted in the prior art, the internal and external tooth nut has the advantages that: the outer teeth of the inner and outer tooth nuts are firmly screwed into the box plate instead of being mechanically nailed into the box plate, so that the inner and outer tooth nuts are repeatedly disassembled and cannot be tripped, and the assembly, the disassembly and the accessory replacement are convenient. The claw of the four-claw nut used in the existing turnover box is provided with the barb, the claw of the four-claw nut is inconvenient to detach, the barb on the claw of the four-claw nut can be pulled to hurt a plate after the four-claw nut is forcibly detached, and particularly the detached claw nut is damaged and cannot be reused, so that high cost and great difficulty are brought to maintenance and replacement.

In summary, the lock hook and the lock catch are screwed in series with the inner and outer tooth nuts through the bolts to form a firm fixing piece, the L-shaped lock hook is connected with the lock catch to form an integral connecting fastener, and the reinforcing ribs are arranged outside the L-shaped lock hook to improve deformation resistance, so that the connecting and locking structure of the invention is formed, and the practicability, safety and stability of the invention are far superior to those of the existing turnover box.

The box assembling and box disassembling of the invention are three-none operation, namely: no nail, no steel belt and no zero disassembly. The packaging method is convenient and quick, and the recyclable packaging cost is the lowest. The invention has strong standardization universality. The box board and the fastener are standardized, are generally exchanged, and are convenient to maintain and low in cost. The volume of the single-box recovery stacking is only 1/5-1/4 of that of the single-box recovery stacking when in use, thereby greatly reducing the cost of storage and transportation. In the transportation process of transporting goods and the turnover box, the turnover box can be quickly disassembled and assembled, and the lock catch can be opened only by taking down the locating pin or the nylon-tightening lock bar, so that the disassembly and assembly time is greatly shortened compared with that of the existing turnover box, and the effect is particularly obvious under the condition of very large disassembly and assembly amount. Avoiding the economic loss caused by loosening, falling and puncturing the packaging bag of the nut with the claw after repeated disassembly and assembly.

Detailed Description

As shown in fig. 1-5, the invention is a zero-dismantling turnover box, which is a box body formed by six box boards, namely a bottom board 7, two first side boards 5, two second side boards 6 and a cover board 1, wherein 4 wood beams 12 are arranged below the bottom board. Two adjacent box boards are perpendicular to each other, the end part of one box board is connected with the board surface on one side of the end part of the other box board, and a connecting piece 16 and a fixed angle 2 are arranged at the corner of the box body.

The connecting piece 16 is composed of an L-shaped lock hook 3 which covers the edge of the box body and the length of which exceeds the gap of the box body plate, and a lock catch 4 which is connected with the L-shaped lock hook 3, so that a quick-dismantling structure is formed. The L-shaped latch hook 3 is L-shaped, and the front end of the L-shaped latch hook is provided with a hook head 10 facing away from the box body.

The connecting piece 16 is connected and fixed on the edge of the box body through bolts and the inner and outer tooth nuts 13 screwed into the box plates. The box corner positions are all provided with screw holes, the inner and outer tooth nuts are arranged in the screw holes, the inner and outer tooth nuts are countersunk nuts and screwed into the box plate, the box is completely embedded, and the problem that four-claw screws are easy to fall off and puncture packaging bags in the prior art is solved. The connecting piece 16 and the fixed angle 2 are fixed on the box body through the inner teeth 15 screwed into the inner and outer tooth nuts 13 by bolts 14. The fixed angle 2 is connected with the bottom plate 7 or the inner and outer tooth nuts 13 on the cover plate 1 through a bolt. The end of the hook head 10 is parallel to the box body or the end of the hook head 10 is inclined to the side of the surface of the box body, and the preferable inclination angle is 3-5 degrees, so that the phenomenon that the box body surface is scratched by the end of the hook head 10 and then is affected with damp and mould is avoided after the turnover box is recovered and stacked, and the service life of the box plate is prolonged.

Each side of the cover plate 1 and each side of the bottom plate 7 are covered by the L-shaped latch hook 3, and compared with the arrangement of the latch 4 of the cover plate 1 and the bottom plate 7, the method provides convenience for assembling each box plate; the two sides of the first side plate 5, which are perpendicular to the bottom plate 7, cover the L-shaped latch hooks 3, and a lock catch 4 is arranged at the plate surface connected with the cover plate 1 and the bottom plate 7; the four sides of the second side plate 6 are provided with the lock catches 4.

As shown in fig. 6-7, the two first side plates 5 are oppositely arranged at two sides of the bottom plate 7, and two side end surfaces perpendicular to the bottom plate 7 are provided with L-shaped clamping grooves 8; the two second side plates 6 are oppositely arranged and clamped in the L-shaped clamping grooves 8 on the opposite sides of the two first side plates 5, and the L-shaped clamping grooves 8 can fix the two second side plates 6 so that the second side plates 6 do not incline in transportation, and the limiting effect is achieved.

As shown in fig. 10-11, the L-shaped latch hook 3 is provided with a reinforcing rib 9 at the lower part of the opening of the hook head 10, and the reinforcing rib 9 is consistent with the long side of the L-shaped latch hook 3, so as to strengthen the strength of the L-shaped latch hook 3, ensure that the L-shaped latch hook 3 is not deformed in the process of transporting liquid materials, and further ensure that the gaps between the box boards are tight.

As shown in fig. 8-9, the hook head 10 of the L-shaped latch hook 3 is connected with a locking ring 11 on the lock catch 4. The lock catch 4 is connected with the L-shaped lock hook 3 and then locked in the opposite direction of the hook head 10, the tightening distance is 7-10 mm, and the tail of the lock catch 4 is inserted with a locating pin or a nylon tightening locking strip, so that the lock catch 4 is prevented from being spread in the transportation process, and the gap of the box body is kept tight.

After the box board is disassembled, the stacking sequence of the box boards is as follows from top to bottom: the bottom plate 7, one second side plate 6, two first side plates 5, one second side plate 6 and the cover plate 1.

The two first side plates 5 are stacked back to back, the L-shaped locking hooks 3 arranged on the two first side plates 5 are respectively inserted with the L-shaped locking hooks 3 arranged on the cover plate 1 and the bottom plate 7, the second side plates 6 are clamped in the L-shaped locking hooks, the locking rings 11 of the locking hooks 4 are on the same plane with the locking hooks 4, the damage of the box plates in self-disassembly transportation is avoided, the occupied volume of a single box is reduced to the maximum extent, the transportation cost is reduced, and the space utilization rate of a transportation tool is improved.

Examples:

As shown in figure 1, the zero-dismantling turnover box comprises a box body consisting of six multi-layer glued wooden box boards, namely a bottom board 7, two first side boards 5, two second side boards 6 and a cover board 1, wherein 4 wooden beams 12 are arranged below the box body, the surface of the box body is smooth, burrs are avoided, and the thickness of the box body is 20-30 mm.

Four wood beams 12 are arranged below the bottom plate 7 at intervals, the four wood beams 12 are parallel to the plate surface of the first side plate 5, and forklift transportation is facilitated. Two adjacent box boards are perpendicular to each other, and the end part of one box board is connected with the board surface on one side of the end part of the other box board. Wherein, the two first side plates 5 are oppositely arranged at two sides of the bottom plate 7, and L-shaped clamping grooves 8 are formed on the end surfaces of the two sides perpendicular to the bottom plate 7; the two second side plates 6 are oppositely arranged and clamped in the L-shaped clamping grooves 8 on the opposite sides of the two first side plates 5, a fixed angle 2 is respectively arranged at eight vertex angles of the box body, and the fixed angle 2 is connected with the plane at the corner of the bottom plate 7 or the cover plate 1 through a bolt; five sets of connecting pieces 16 are respectively covered on four connecting edges of the side face of the box body, and two sets of connecting pieces 16 are respectively covered on eight connecting edges of the cover plate 1, the bottom plate 7 and the four side plates. Each connecting edge between the plates of the box body covers the L-shaped lock hook 3 with the length of 40-60 mm exceeding the gap between the plates of the box body.

In the process of transporting liquid, the L-shaped clamping groove 8 formed in the plate edge of the first side plate 5 is matched with the connecting piece 16 arranged on the side edge of the box body, and the L-shaped clamping groove and the second side plate 6 are mutually limited, so that each box plate of the turnover box is prevented from inclining inwards.

In the disassembly and transportation process, the stacking sequence of the box boards is as follows from top to bottom: the cover plate 1, one second side plate 6, two first side plates 5, one second side plate 6 and the bottom plate 7.

The two first side plates 5 are stacked back to back, the L-shaped locking hooks 3 arranged on the two first side plates 5 are respectively penetrated with the L-shaped locking hooks 3 arranged on the cover plate 1 and the bottom plate 7, and the second side plates 6 without protruding connecting pieces are clamped in the L-shaped locking hooks to protect the side plates.

The preferred placement mode of the first side plates 5 is that the sides with the locking catches 4 on the two first side plates 5 should be placed vertically, and because the thickness of the locking catches 4 on the first side plates 5 is larger than the height of the L-shaped locking hooks 3, when stacking, the supporting points of the first side plates 5 are only four locking catches 4 in the middle of the plate where the two sides are located, so that in order to keep stacking balance, the sides with the locking catches 4 on the two first side plates 5 should be placed vertically. The stabilizing effect of the placement mode is particularly remarkable when the number of stacked boxes is large and the number of layers is high in the stacking and transferring process of the turnover boxes.

As shown in fig. 12, the connecting piece 16 and the fixing angle 2 are connected with the box body in such a way that the inner and outer thread nuts 13 are screwed into the screw holes, and the connecting piece 16 is fixed on the box body by matching the inner thread nuts 13 and the inner thread 15 through bolts 14. The L-shaped lock hook 3 with the reinforcing rib 9 is provided with the hook head 10, the length of one end of the L-shaped lock hook exceeds the butt joint side seam of two box boards by about 5 cm, when a wooden box is added into a liquid cargo bag without a fixed shape, liquid expands outwards, the box boards around the box body can shift outwards due to stress, and at the moment, the connecting piece 16 can firmly lock the box boards and cannot shift outwards.

The test result of the filled saturated brine proves that: the invention is full (about 1.5 tons) of brine, and the gaps between the box boards are hardly changed. The connecting method can ensure that the gap between the box plates of the box body is minimum, and the gap between the box plates of the box body is still very small under the conditions that the liquid expands outwards and jolts and shakes when the liquid is transported, so that unnecessary loss in liquid transportation is avoided.

Counterexample:

the extension length of the head end of the L-shaped latch hook in the connecting piece is exactly the same as the gap-to-edge distance of the box body, and the other configurations are the same as the above embodiments.

After the turnover box is assembled, the L-shaped lock hook head end is just positioned at the gap of the box body plate, when liquid is transported under the conditions of expanding outwards and jolting and shaking, all the box plates of the box body are stressed, the gap between the box plates is increased due to the fact that the support of the L-shaped lock hook head end extending structure is not available, and the connection between the L-shaped lock hook and the lock catch is easy to release due to the action of the outwards expanding force, and the risk of clamping bags exists, so that unnecessary loss in liquid transportation is caused.

The invention has convenient disassembly and low cost. The L-shaped lock hook and the lock catch connection between the box bodies can be released by directly opening the lock catch, the box plates of the box bodies can be separated, and the separated box plates are stacked together, so that the recovery volume is reduced.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should be covered by the protection scope of the present invention by making equivalents and modifications to the technical solution and the inventive concept thereof.
