It mainly includes a bearing platform 1, a slide assembly 2, a flip assembly 3, an L-shaped bracket 4 and an atomic box unit 5, etc.; wherein the bearing platform 1 has a planar structure and can be fixed on a vehicle chassis or on a shelf; the slide assembly 2 is arranged above the bearing platform 1, and its sliding part can reciprocate relative to the bearing platform 1 if fixed by a bolt assembly; the flip assembly 3 is hinged to the side edge of the slide assembly 2 and rotates around the side edge of the slide assembly 2; the L-shaped bracket 4 is an L-shaped structure, which is arranged on one side of the flip assembly 3 and rotates synchronously with the flip assembly 3, and slides with the slide assembly 2 when flipped to the top of the bearing platform 1; the atomic box unit 5 cooperates with the L-shaped bracket 4, and after being combined with the L-shaped bracket 4, it rotates synchronously with the flip assembly 3, and can be separated from the flip assembly 3 after being loosened, with a simple structure and convenient disassembly and assembly.

[0062] In one embodiment, the auxiliary loading and unloading device also includes a rolling assembly 6 fixed on the slide assembly 2. When the flipping assembly 3 rotates, the rolling assembly 6 rolls with the L-shaped bracket 4 to provide support and reduce friction, making the flipping smoother and more labor-saving.

[0063] In one embodiment, if Figure 4 As shown, the slide assembly 2 is used to realize the horizontal pushing of the L-shaped bracket 4 and the atomic box unit 5, and includes an adapter plate 21 fixed on the upper end surface of the bearing platform 1, through which the auxiliary loading and unloading device as a whole can be combined and separated with the shelf or the vehicle chassis; a slide rail 22 is fixedly installed on the upper end surface of the adapter plate 21, and a slider 23 that slides with the slide rail 22 is provided on the slide rail 22, and limited support seats 25 are respectively provided at both ends to limit the sliding stroke. In this embodiment, the upper end surfaces of the four sliders 23 are simultaneously connected to the sliding bracket 24, and a support block 26 is provided on the sliding bracket 24. A hinge hole 27 is opened in the middle near one end of the flip assembly 3, and the support block 26 is used to support the L-shaped bracket 4 and the atomic box unit 5, and the hinge hole 27 is hinged to the L-shaped bracket 4.

[0064] In one embodiment, if Figure 5As shown, the flip assembly 3 includes an adapter block 31 fixed on one side of the sliding bracket 24, a rotating shaft 32 is passed through the inner side of the adapter block 31, and a force storage elastic member 33 is sleeved on the outer middle part of the rotating shaft 32 located between the two adapter blocks 31, the two ends of the force storage elastic member 33 are respectively abutted against the sliding bracket 24, and the middle part is abutted against the L-shaped bracket 4; the two ends of the rotating shaft 32 are respectively connected to the bearing seat 34 and can rotate relative to the bearing seat 34, and the bearing seat 34 is fixed on the L-shaped bracket 4; when the flip assembly 3 is perpendicular to the supporting platform 1, the force storage elastic member 33 stores the maximum force, and when the flip assembly 3 is parallel to the supporting platform 1, the force storage elastic member 33 stores the force completely or stores the force in the reverse direction. In this embodiment, the force storage elastic member 33 is a torsion spring. When the flip assembly 3 is perpendicular to the carrying platform 1, the force storage is maximum, so that the force for pulling and lifting the atomic box unit 5 when loading goods can be minimized, saving time and effort; when the flip assembly 3 is parallel to the carrying platform 1, the force storage is completely released, and it is further preferred to store force in the reverse direction, so that the force for pulling up the atomic box unit 5 when unloading goods can be reduced, and the same force can be used to lift a heavier atomic box unit 5; when unloading, when it is flipped to a certain angle, forward force storage is performed again, so that the atomic box unit 5 can be smoothly lowered to ensure safe unloading.

[0065] In one embodiment, if Figure 6 and Figure 7 As shown, the L-shaped bracket 4 is welded by pipes and sheet metal, and includes a first bracket 41 and a second bracket 42 which are fixedly connected to each other and perpendicular to each other. A first limit plate 43 is provided at the end of the second bracket 42 close to the first bracket 41, and a second limit plate 44 is provided at the other end of the second bracket 42 and at a position opposite to the first limit plate 43. A sliding groove 45 is opened in the middle of the second bracket 42 and a swing arm 46 is hinged through the sliding groove 45. The other end of the swing arm 46 is connected to the hinge hole 27. By swinging the swing arm 46 along the hinge hole 27, the overall shaking during flipping can be greatly reduced. It should be noted that the first limiting plate 43 has a guide slope and forms a limiting groove with the second bracket 42, and the box bracket 51 of the atomic box unit 5 slides into the limiting groove through the guide slope; the second limiting plate 44 has a V-shaped protrusion and has a certain elasticity, and can be deformed under the action of external force, that is, the box bracket 51 of the atomic box unit 5 can be clamped into or slid out of the second limiting plate 44 by external force, thereby completing the clamping or loosening of the atomic box unit 5.

[0066] Preferably, the L-shaped bracket 4 also includes an elastic block 47 hinged to the second bracket 42, and the elastic block 47 has a built-in spring (not shown); when the atomic box unit 5 is combined with the L-shaped bracket 4, the elastic block 47 is pressed into the second bracket 42 and abuts against the atomic box unit 5 under the action of the spring, thereby further clamping the atomic box unit 5, reducing the shaking of the atomic box unit 5 during rotation, and ensuring the stability of the atomic box unit 5 during flipping; when the atomic box unit 5 is separated from the L-shaped bracket 4, the elastic block 47 is reset under the action of the spring and extends out of the second bracket 42.

[0067] In one embodiment, if Figure 8 As shown, the atomic box unit 5 includes a box support 51 that cooperates with the L-shaped support 4, a cover 52 that surrounds the outer periphery of the box support 51, and at least one set of casters 53 that are symmetrically arranged on the inner side of the box support 51; the box support 51 and the cover 52 enclose the atomic box unit 5 to form a storage space for placing goods. In this embodiment, the casters 53 are set as a group, and when moving, they are like traditional flatbed trucks; in other embodiments, the casters 53 can also be set as two groups, three groups or even four groups, so that the atomic box unit 5 can be pushed smoothly when any side is facing down, which is more applicable.

[0068] In one embodiment, if Fig. 9 and Fig.10 As shown, the cover 52 includes two first sides 521 arranged opposite to each other, a second side 522 and a third side 523 arranged diagonally symmetrically relative to the atomic box unit 5, and a fourth side 524 and a fifth side 525 arranged diagonally symmetrically relative to the atomic box unit 5; wherein, the first side 521 and / or the side opposite thereto are provided with a lock 57 cooperating with the box support 51, and the lock 57 adopts an existing product, which is not described here; the second side 522 and the third side 523 are respectively provided with a first avoidance groove 55; the second side 522 and the fourth side 524, the third side 523 and the fifth side 525, and the fourth side 524 and the fifth side 525 are all provided with a second avoidance groove 56 at the corners where the second side 522 and the fourth side 524, the third side 523 and the fifth side 525 intersect. The first avoidance groove 55 is in a strip-shaped structure, and the second avoidance groove 56 is distributed on both sides of the corner to avoid the user's grip on the box support 51. The first air-avoiding groove 55 and the second air-avoiding groove 56 are both sealed with a deformable material such as cloth, which neither affects the grip during operation nor occupies the internal space of the atomic box unit 5 .

[0069] Preferably, footrests 54 are provided on the second side surface 522 and the third side surface 523 near the casters 53 to facilitate user operation.

[0070] In one embodiment, if Fig.11 As shown, the box support 51 includes a support body 511 and a first cross bar 513 and a second cross bar 514 arranged in the middle of the support body 511; a plurality of the first cross bars 513 are respectively arranged at three corners except the corner where the caster 53 is located, one of which is clamped with the first limit plate 43, and the other is clamped with the second limit plate 44; two second cross bars 514 are respectively arranged at the first avoidance groove 55 of the second side 522 and the third side 523; the support body 511 is also provided with a handle 515 at the corner where the caster 53 is located, and a lock hole 516 is provided at the position where the lock buckle 57 is connected, and the first side 521 is locked and unlocked by the cooperation of the lock buckle 57 and the lock hole 516. In this embodiment, the first cross bar 513 and the second cross bar 514 are of the same structure, both of which are made of pipes, but they are located at different positions.

[0071] Preferably, the box support 51 also includes one or more partitions 512 arranged in the middle of the support body 511. The partitions 512 are detachable and used to divide the internal space of the atomic box unit 5 into multiple subspaces. They are optional devices and can be installed or not as needed. One or more partitions can be installed. The functions of the partitions are: first, the goods in the atomic box unit 5 can be subdivided into different subspaces for easy placement and retrieval; second, the rotation amplitude of the goods inside the box during flipping and transportation can be reduced under the action of the partitions.

[0072] More specifically, the cover 52 is any one or a combination of a whole plate, a mesh plate or a nylon cloth. When the atomic box unit 5 needs to be completely closed, a whole piece of sealing plate such as a plastic plate or a PP honeycomb plate can be used. Otherwise, a mesh plate made of fine metal wires such as Fig.12 As shown, nylon fabric can also be selected as needed. Of course, a combination of the above can also be used, with the actual needs combined with strength and weight reduction design as reference for selection.

[0073] In one embodiment, if Fig.13As shown, the rolling assembly 6 includes a rolling support 61 fixed on the adapter plate 21, and a roller frame 62 is provided on the top of the rolling support 61 and the side wall close to the L-shaped bracket 4, and a roller 63 is installed on the roller frame 62. When the flip assembly 3 starts to rotate, the second bracket 42 of the L-shaped bracket 4 forms a certain angle with the bearing platform 1, and at this time, the second bracket 42 rolls with the roller 63 close to the side of the L-shaped bracket 4; when it rotates to the top of the bearing platform 1, the second bracket 42 of the L-shaped bracket 4 is parallel to the bearing platform 1, and at this time, the second bracket 42 rolls with the roller 63 on the top of the rolling support 61, and the roller 63 can play a role in supporting and reducing friction during flipping and pushing, making the operation more labor-saving.

[0074] When in use, unlock the lock 57, open the first side 521, place the goods to be transported into the storage space of the atomic box unit 5, close the first side 521 again and lock it through the cooperation between the lock 57 and the lock hole 516. Fig.14 As shown, the atomic box unit 5 is pushed so that its docking surface faces the flip assembly 3 on one side of the bearing platform 1 and moves to above the first bracket 41, and then the user steps on the footrest 54 with his foot to make the other end of the atomic box unit 5 tilt up, and the first cross bar 513 at the bottom slides along the guide slope of the first limit plate 43 into the limit groove formed between the first limit plate 43 and the second bracket 42. At this time, the first bracket 41 is close to the ground under the gravity of the atomic box unit 5, and the stored force of the force storage elastic member 33 reaches the maximum; then the atomic box unit 5 is rotated clockwise along the first cross bar 513 at the bottom, and the middle part of the opposite side contacts the elastic block 47 and presses the elastic block 47 into the second bracket 42 under the action of external force, and the first cross bar 513 at the top is also stuck in the second limit plate 44 under the action of external force, so that the atomic box unit 5 is locked with the L-shaped bracket 4.

[0075] Hold the first cross bar 513 close to the user, rotate around the rotating shaft 32 as the central axis, and lift the atomic box unit 5 upward. At this time, the L-shaped bracket 4 is in rolling contact with the roller 63 on the side, and the swing arm 46 rotates synchronously; continue to lift it upward with the assistance of the force storage elastic member 33, and switch hands to the second cross bar 514 on the third side 523, the handle 515 and the second cross bar 514 on the second side 522 in turn during the flipping process, so as to flip the atomic box unit 5 to the top of the supporting platform 1. At this time, the atomic box unit 5 is flipped from a vertical state to a horizontal state, and the user continues to hold the second cross bar 514 on the second side 522 to push the atomic box unit 5 forward, and moves along the slide assembly 4 and the top roller 63 until the slider 23 contacts the limit support 25, and the loading is completed.

[0076] The unloading operation is the reverse operation and will not be elaborated here; it should be noted that: when the atomic box unit 5 is flipped from a horizontal state to a vertical state, the user needs to step on the footrest 54 to tilt the atomic box unit 5 so that the top first cross bar 513 slides out of the second limit plate 44, and the bottom first cross bar 513 slides out of the first limit plate 43, and then pulls it out to complete the unloading.

[0077] It should be noted that the atomic box unit 5 and the flip assembly 3 are not combined one-to-one, but can be combined randomly. For example, after a fully loaded atomic box unit 5 is unloaded, an empty atomic box unit 5 can be loaded, which is very flexible in application.

[0078] In this embodiment, a slide assembly is installed on a load-bearing platform, and a flip assembly is installed on one side of the slide assembly. The flip assembly is connected to an L-shaped bracket, and the L-shaped bracket is clamped with the atomic box unit. The atomic box unit is flipped upward by manually holding the handle and the cross bar of the atomic box unit. With the cooperation of the flip assembly and the L-shaped bracket, the atomic box unit loaded with the goods to be transported is flipped to the top of the load-bearing platform, that is, flipped from vertical to horizontal, and then slid along the slide assembly to a predetermined limit position, thereby completing the loading of the goods; the opposite operation is adopted when unloading; using this device to realize the loading and unloading operations of heavier weight goods without the aid of additional tools such as forklifts, greatly improving efficiency, while reducing the risk of work-related injuries caused by heavy object handling, and does not require electricity or the use of additional power structures such as hydraulics and pneumatics. It has a simple structure, low cost and failure rate, and is convenient and quick to operate, saving time and effort.

Please refer to the above for the specific use process, which will not be repeated here.

[0080] It should be noted that the auxiliary loading and unloading device can be one or more. When multiple devices are deployed, they can be placed on the same side of the carrying platform 1, or they can be arranged on different sides and staggered with each other.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
