Description

Technical Field

[0001] The invention relates to the technical field of single-phase module packaging, and in particular to a logistics packaging box for a single-phase module. Background Art

[0002] The single-phase module needs to be carefully designed in logistics packaging to ensure that the product is not damaged during transportation, storage and delivery. The packaging design must not only take into account the size and weight of the single-phase module itself, but also provide adequate protection based on various environmental factors during transportation. The main function of the packaging box is to protect the integrity of the single-phase module during transportation and to provide solutions that are easy to handle, store and distribute. The existing packaging boxes are protective, stable, identifiable and economical.

[0003] The existing packaging design can protect the safety of single-phase modules during transportation, improve logistics efficiency and reduce transportation costs, but the following problems still exist: when transportation personnel use dedicated packaging boxes to package and transport single-phase modules, in order to improve transportation efficiency, multiple packaging boxes are usually stacked together to reduce the occupied storage space, but during transportation or delivery, staff need to regularly conduct spot checks on the single-phase modules in the packaging boxes to ensure that the products are not damaged during transportation and meet factory standards. The packaging boxes containing single-phase modules are stacked together, making it difficult for staff to conduct spot checks on the single-phase modules in the middle packaging box, and then they need to move the upper packaging box to inspect the single-phase modules in the middle packaging box. This process increases the difficulty of the staff's spot check work and increases the risk of damage to the single-phase modules during transportation. Summary of the invention

[0004] In view of the problem in the prior art that packaging boxes are stacked together, making it difficult for staff to conduct spot checks on single-phase modules inside the middle packaging box, a logistics packaging box for single-phase modules is proposed.

[0005] The present application provides a logistics packaging box for single-phase modules, the purpose of which is: by setting a sliding component, the packaging board is located in a locking ring and is in a fixed state under normal transportation conditions. When the staff needs to conduct a random inspection of the single-phase module in the packaging board, the packaging board can be placed in a sliding state through the locking component, and the packaging board can be pulled out of the locking ring through the pulling groove to inspect the single-phase module inside. The single-phase module in the middle packaging board can be randomly inspected without moving the packaging boards stacked above, which effectively improves the inspection efficiency and reduces the workload of the staff.

[0006] The technical solution of the present invention is: a logistics packaging box for a single-phase module, comprising a bottom plate and a single-phase module, and also comprising a packaging unit arranged on the bottom plate, wherein the packaging unit comprises a placing component and a sliding component arranged on the bottom plate;

[0008] The inner ring of the retaining ring and the end face of the packaging plate are both set to be square, and the size of the inner ring end face of the retaining ring is slightly larger than the size of the outer ring end face of the packaging plate. The limiting ring is used to limit the vertical direction of the packaging plate. The size of the placement groove is equal to the size of the single-phase module. The single-phase module is provided with terminals, and the terminal groove is used to place the terminals in the single-phase module.

[0009] Furthermore, the direction foolproofing component includes two chamfers arranged at one end of the retaining ring, and two rounded corners arranged at an end of the retaining ring away from the chamfers.

[0010] Furthermore, the sliding component includes an installation groove opened at the lower end of the limiting ring and the upper end of the bottom plate, a plurality of rotating shafts arranged in the installation groove, sliding wheels arranged on the plurality of rotating shafts, and a sliding groove opened on the packaging board, one end of the plurality of sliding wheels slides in the corresponding sliding groove, the distance between the corresponding sliding wheels on the upper and lower sides is equal to the width of the packaging board, and a locking component is arranged on the limiting ring.

[0011] Furthermore, the locking assembly includes a square groove opened on the limiting ring, a through groove opened at the lower end of the square groove, a rotating rod arranged on the side wall of the square groove, a driven gear arranged on the outer wall of the rotating rod, a mounting ring arranged on the outer wall of the rotating rod, and a locking rod arranged on the mounting ring, wherein the locking rod is located directly above the through groove, and a control element is installed in the limiting ring.

[0012] Furthermore, the control element includes a horizontal groove opened in the limit ring, a sliding plate slidably set in the horizontal groove, a control sliding button set on the sliding plate, a sliding seat plate set at the lower end of the square groove, a sliding tooth plate slidably set in the sliding seat plate, a connecting plate set on the side wall of the sliding tooth plate, a connecting block set on the side wall of the sliding plate, and a pulling plate set between the connecting plate and the connecting block, the sliding tooth plate is meshed with the lower end of the driven gear, and a safety piece is installed on the side wall of the limit ring.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1 - Figure 4 , which is the first embodiment of the present invention, provides a logistics packaging box for a single-phase module, including a base plate 1 and a single-phase module, and also includes a packaging unit installed on the base plate 1, and the packaging unit includes a placing component and a sliding component installed on the base plate 1.

[0035] The placement components include a retaining ring 2 fixedly mounted on the base plate 1, a limiting ring 3 fixedly mounted on the inner wall of the retaining ring 2, a packaging plate 4 slidably mounted on the base plate 1, a placement groove 5 provided on the packaging plate 4, a terminal groove 6 provided in the placement groove 5, two convex corner blocks 7 fixedly mounted on the side wall of the packaging plate 4, and a direction anti-mistake assembly is provided on the retaining ring 2.

[0036] The inner ring of the retaining ring 2 and the end face of the packaging plate 4 are both set to be square, and the size of the inner ring end face of the retaining ring 2 is slightly larger than the size of the outer ring end face of the packaging plate 4. The limiting ring 3 is used to limit the vertical direction of the packaging plate 4. The size of the placement groove 5 is equal to the size of the single-phase module. The single-phase module is provided with terminals, and the terminal groove 6 is used to place the terminals in the single-phase module.

[0037] Reference Figure 3 and Figure 4 The bottom plate 1, the retaining ring 2, the limiting ring 3 and the packaging board 4 are a whole and are collectively referred to as a packaging box. The direction fool-proofing component includes two chamfered corners 8 opened at one end of the retaining ring 2, and two rounded corners 9 opened at the end of the retaining ring 2 away from the chamfered corners 8. The direction fool-proofing component is used for the staff to determine the direction of the packaging board 4 to ensure that the staff can quickly determine the placement direction when stacking the packaging boards 4, which is convenient for subsequent identification and transportation. The packaging board 4 is made of three-wall corrugated cardboard.

[0038] Specifically, the placement component is used to place a single-phase module. The single-phase module has a protruding terminal. Therefore, by setting the terminal groove 6, the single-phase module can be placed horizontally in the placement groove 5 to prevent the single-phase module from protruding due to the terminal and affecting the subsequent stacking. The packaging board 4 is made of three-wall corrugated cardboard to improve the compression resistance and buffering performance. The external corrugated cardboard improves the strength of the structure, and the internal corrugated cardboard is used to absorb impact force. The convex corner block 7 facilitates manual placement of the stacked packaging boards 4, avoiding the side handle position for easy transportation.

[0039] During use, the staff will place the single-phase modules that need to be transported in the placement slots 5 on the packaging board 4 in the packaging box, and place the terminals of the single-phase modules into the terminal slots 6 accordingly, so that the single-phase modules are just placed in the placement slots 5. After placement is completed, the packaging boxes are stacked in sequence and placed in the transport box to complete the placement of the single-phase modules.

[0040] Example 2, reference Figure 5 - Fig.11, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the sliding component includes a mounting groove 10 opened at the lower end of the limiting ring 3 and the upper end of the bottom plate 1, a plurality of rotating shafts 11 fixedly installed in the mounting groove 10, sliding wheels 12 rotatably installed on the plurality of rotating shafts 11, and a sliding groove 13 opened on the packaging board 4. One ends of the plurality of sliding wheels 12 slide in the corresponding sliding grooves 13, the distance between the corresponding sliding wheels 12 on the upper and lower sides is equal to the width of the packaging board 4, and a locking component is provided on the limiting ring 3.

[0041] Specifically, the sliding component is used to enable the packaging board 4 to slide freely in the limiting ring 3 when it is installed between the limiting ring 3 and the bottom plate 1, so that when the staff needs to conduct a spot check on the single-phase modules in the stacked packaging boards 4, the packaging board 4 to be checked can be pulled out of the locking ring 2 by pulling the packaging board 4 (refer to Fig.11 ), thereby achieving the ability to spot check the single-phase modules inside the packaging board 4 to be spot checked without moving other packaging boards 4 stacked on the packaging board 4 to be spot checked, effectively improving the spot check efficiency of the staff and reducing the workload of the staff. By providing a mounting groove 10 at the lower end of the limit ring 3 and the upper end of the bottom plate 1, and installing a rotating sliding wheel 12 in the mounting groove 10 through a plurality of rotating shafts 11, the packaging board 4 is slidably installed between the corresponding sliding wheels 12 at the upper and lower ends through the sliding groove 13, so that the packaging board 4 can move freely between the limit ring 3 and the bottom plate 1, and realize the pulling function.

[0042] Reference Figure 8 - Fig.10 The locking assembly includes a square groove 14 formed on the limiting ring 3, a through groove formed at the lower end of the square groove 14, a rotating rod 15 rotatably mounted on the side wall of the square groove 14, a driven gear 16 fixedly mounted on the outer wall of the rotating rod 15, a mounting ring 17 fixedly mounted on the outer wall of the rotating rod 15, and a locking rod 18 fixedly mounted on the mounting ring 17. The locking rod 18 is located directly above the through groove, and a control element is installed in the limiting ring 3. The control element includes a horizontal groove 19 opened in the limit ring 3, a sliding plate 20 slidably installed in the horizontal groove 19, a control slide button 21 fixedly installed on the sliding plate 20, a sliding seat plate 22 fixedly installed at the lower end of the square groove 14, a sliding tooth plate 23 slidably installed in the sliding seat plate 22, a connecting plate 24 fixedly installed on the side wall of the sliding tooth plate 23, a connecting block 25 fixedly installed on the side wall of the sliding plate 20, and a pulling plate 26 fixedly installed between the connecting plate 24 and the connecting block 25. The sliding tooth plate 23 is meshed with the lower end of the driven gear 16. A safety piece is installed on the side wall of the limit ring 3, and a pulling groove 31 is opened at the lower end of the two convex corner blocks 7.

[0043] Specifically, the locking assembly is used to limit the packaging board 4 that is slidably installed between the limit ring 3 and the base plate 1. When the staff needs to transport the packaging board 4 normally, the packaging board 4 is limited in the horizontal direction through the locking rod 18 on the locking assembly, so that the packaging board 4 cannot slide freely on the limit ring 3 and the base plate 1, thereby ensuring the stability of the packaging board 4 during transportation. During transportation or delivery, the locking rod 18 can be rotated to release the limitation on the packaging board 4, and then the packaging board 4 can be pulled out of the base plate 1. At this time, the staff does not need to carry the upper packaging board 4, and can conduct random inspections on the single-phase modules inside the packaging board 4 in the middle position of the stack, thereby effectively improving the inspection efficiency of the staff and reducing the workload of the staff. Under normal transportation conditions, the locking rod 18 is in a direction perpendicular to the horizontal direction. Therefore, under normal transportation conditions, the lower end of the locking rod 18 limits the horizontal direction of the packaging board 4 to prevent the packaging board 4 from sliding in the horizontal direction due to shaking during transportation. When the staff needs to detect the single-phase module in the packaging board 4, the locking rod 18 is rotated 90°. At this time, the direction of the locking rod 18 is parallel to the horizontal direction. At this time, the locking rod 18 no longer limits the packaging board 4, and the packaging board 4 can be pulled out of the bottom plate 1 through the pulling groove 31, and the staff can directly check the single-phase module in the packaging board 4.

[0044] During use, when the staff needs to conduct spot checks on the single-phase modules in the packaging box during transportation or delivery, the staff pulls the control slide button 21 to slide horizontally to the left in the horizontal slot 19 (refer to Fig. 9 , Fig. 9 2 is a schematic diagram of the structure after the control slide button 21 slides). At this time, the control slide button 21 drives the connecting block 25 to move synchronously through the sliding plate 20. During the movement of the connecting block 25, the sliding tooth plate 23 is driven to move synchronously through the pull plate 26 and the connecting plate 24. During the movement of the sliding tooth plate 23 to the left, the driven gear 16 is driven to rotate clockwise (refer to Fig. 9 ), the driven gear 16 drives the locking rod 18 to rotate synchronously clockwise through the rotating rod 15 and the mounting ring 17, so that the locking rod 18 is completely located in the square groove 14 and no longer limits the packaging board 4 in the horizontal direction. At this time, the staff pulls the pulling groove 31 at the lower end of the convex corner block 7 to pull the packaging board 4 out of the bottom plate 1. The staff can directly take out the single-phase module in the packaging board 4 to inspect it. After the inspection is completed, the single-phase module is placed in place, and the packaging board 4 is pushed onto the bottom plate 1, and the control slider 21 is slid in the reverse direction. At this time, the driven gear 16 is reset, thereby driving the locking rod 18 to reset, so that the locking rod 18 limits the packaging board 4 again to ensure stability during subsequent transportation.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3, reference Figure 8 - Fig.10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the safety member includes a bearing plate 27 fixedly mounted on the side wall of the limiting ring 3, a threaded groove provided on the bearing plate 27, a threaded rod 28 threadedly installed in the threaded groove, a knob 29 fixedly mounted on the upper end of the threaded rod 28, and a locking groove 30 provided on the upper end of the control slide button 21, and the end surface size of the locking groove 30 is larger than the end surface size of the lower end of the threaded rod 28.

[0047] Specifically, the safety piece is inserted into the locking groove 30 through the threaded rod 28 to lock the control slide button 21, preventing the control slide button 21 from sliding due to shaking or external factors during transportation, thereby causing the locking rod 18 to release the limit on the packaging board 4. The safety piece effectively improves the transportation stability of the single-phase module.

[0048] During use, when the staff needs to inspect the single-phase module inside the packaging box stacked in the middle position, the staff rotates the threaded rod 28 to make the threaded rod 28 move vertically upward along the threaded groove, so that the lower end of the threaded rod 28 disengages from the threaded groove, and the staff slides the control slider 21 to the left to release the limit on the packaging board 4, so that the packaging board 4 can slide in the horizontal direction. After the inspection is completed and the packaging board 4 is reset, the control slider 21 is slid in the opposite direction to reset the control slider 21, and the threaded rod 28 is rotated so that the threaded rod 28 is inserted into the threaded groove, and the control slider 21 is limited and locked again.

[0049] The remaining structure is the same as that of Example 2.

[0050] Based on Examples 1-3, the working principle of the present invention is as follows: the staff places the single-phase modules to be transported in the placement slots 5 on the packaging board 4 in the packaging box, and places the terminals of the single-phase modules into the terminal slots 6 accordingly, so that the single-phase modules are just placed in the placement slots 5. After the placement is completed, the packaging boxes are stacked in sequence and placed in the transport box to complete the placement of the single-phase modules.

[0051] When the staff needs to conduct a spot check on the single-phase modules in the packaging box during transportation or delivery, they rotate the threaded rod 28 so that the threaded rod 28 moves vertically upward along the thread groove, so that the lower end of the threaded rod 28 is separated from the thread groove, and the threaded rod 28 is unlocked from the control slider 21. The staff pulls the control slider 21 to slide horizontally to the left in the horizontal groove 19 (refer to Fig. 9 , Fig. 92 is a schematic diagram of the structure after the control slide button 21 slides). At this time, the control slide button 21 drives the connecting block 25 to move synchronously through the sliding plate 20. During the movement of the connecting block 25, the sliding tooth plate 23 is driven to move synchronously through the pull plate 26 and the connecting plate 24. During the movement of the sliding tooth plate 23 to the left, the driven gear 16 is driven to rotate clockwise (refer to Fig. 9 ), the driven gear 16 drives the locking rod 18 to rotate synchronously clockwise through the rotating rod 15 and the mounting ring 17, so that the locking rod 18 is completely located in the square groove 14 and no longer limits the packaging board 4 in the horizontal direction. At this time, the staff pulls the pulling groove 31 at the lower end of the convex corner block 7 to pull the packaging board 4 out of the base plate 1, and the staff can directly take out the single-phase module in the packaging board 4 for inspection.

[0052] After the inspection is completed, the single-phase module is placed in place, the packaging plate 4 is pushed onto the bottom plate 1, and the control slider 21 is slid in the reverse direction. At this time, the driven gear 16 is reset, and then the locking rod 18 is reset, so that the locking rod 18 limits the packaging plate 4 again, and the threaded rod 28 is rotated so that the threaded rod 28 is inserted into the threaded groove, and the control slider 21 is limited and locked again.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
