Description

Technical Field

[0001] This invention relates to the field of express delivery box technology, specifically to a shared express delivery box opening and closing structure and method. Background Technology

[0002] Shared parcel boxes are reusable parcel packaging containers. Traditional parcel packaging is mostly for single use, which generates a lot of waste and puts great pressure on the environment. Shared parcel boxes can be reused multiple times, reducing the consumption of single-use packaging materials such as cardboard boxes and plastic bags, reducing resource waste and environmental pollution. Shared parcel boxes usually adopt standardized designs, which are easy to load, unload and transport, improving the efficiency of parcel delivery.

[0003] Chinese patent CN213110265U proposes a shared express box, including an outer box body, an outer cover, an inner cover, a connecting component, and a combination lock. The top of the outer box body is open, and the interior of the outer box body has a receiving cavity. The outer box body is hinged to one side of the outer cover. The inner cover covers the top opening of the outer box body. The connecting component and the combination lock are both located on the inner cover. The connecting component locks and opens the inner cover and the outer box body, and the combination lock locks the connecting component, providing security for the shared express box.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent uses a connecting component to lock and open the inner cover and the outer box, and has a combination lock to lock the connecting component, providing security for the shared express box. However, it cannot effectively observe whether the shared express box has been opened, and it cannot be quickly unfolded and folded, which is not conducive to storage.

[0006] 2. This patent does not allow for rapid adjustment of the internal space of the shared express box, which is not conducive to reducing the amount of filler material consumed by fixed items.

[0007] Based on this, the present invention designs a shared express box opening and closing structure and method to solve the above problems. Summary of the Invention

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a shared express box opening and closing structure and method.

[0018] To better achieve the objectives of this invention, this invention also provides a method for opening and closing a shared express box, comprising the following steps:

[0019] Step 1: Rotate the first side plate and the second side plate. The torsion springs of the first side plate's rotating shaft and the second side plate's rotating shaft both undergo elastic deformation. The rotation of the first side plate drives the main rotating plate to rotate, the rotation of the main rotating plate drives the first triangular plate to rotate, the rotation of the first triangular plate drives the auxiliary rotating plate to rotate, and the rotation of the auxiliary rotating plate drives the second triangular plate to rotate, thus rotating the first side plate to be perpendicular to the bottom plate. The rotation of the second side plate drives the telescopic plate to rotate. While rotating, the telescopic plate moves away from the second side plate, causing the first spring to undergo elastic deformation, thus rotating the second side plate to be perpendicular to the bottom plate.

[0020] Step 2: Loosen the nut and move the sliding plate to the appropriate position. The movement of the sliding plate will cause the left side of the first rotating bracket to slide on the sliding plate. The second rotating bracket will rotate as it moves with the first rotating bracket. Tighten the nut to fix the first rotating bracket on the sliding plate. The first rotating bracket and the second rotating bracket will fix the sliding plate. The partition is fixedly installed on the end of the sliding plate near the nut. The partition is fixed so that the internal space of the shared express box is limited to a suitable size, and at the same time, the first side plate and the second side plate will not rotate at too many angles.

[0021] Step 3: Move the irregularly shaped sliding plate of the locking component towards the second spring. The second spring undergoes elastic deformation. Close the first and second top covers, release the irregularly shaped sliding plate, and the elastically deformed second spring returns to its original state. Push the irregularly shaped sliding plate back to its initial position, and the irregularly shaped sliding plate enters the slot of the second top cover, locking the first and second top covers. The label cable tie is placed in the openings on the upper side of the irregularly shaped sliding plate and the upper side of the first top cover, locking the shared express box and quickly identifying whether the shared express box has been opened.

[0022] Step 4: When you want to open the shared parcel box, cut the label cable ties, move the irregularly shaped sliding plate of the locking component towards the second spring, open the first and second top covers, release the irregularly shaped sliding plate, the torsion spring that has undergone elastic deformation returns to its original state, causing the first and second side plates to rotate, loosen the nut, move the sliding plate to the initial position, the first and second side plates will rotate and the shared parcel box will be fully unfolded, allowing you to take out the items.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. The torsion spring, which undergoes elastic deformation, restores its original state and drives the first side plate to rotate. The rotation of the first side plate initially unfolds the first side plate. The rotation of the first side plate drives the main rotating plate to rotate, which in turn drives the first triangular plate to rotate. The rotation of the first triangular plate drives the auxiliary rotating plate to rotate, which in turn drives the second triangular plate to rotate, thus fully unfolding the first side plate. This facilitates the first side plate and the bottom plate being in the same plane, reducing the storage space. The torsion spring, which undergoes elastic deformation, restores its original state and drives the second side plate to rotate. The rotation of the second side plate drives the telescopic plate to rotate. The end of the telescopic plate away from the second side plate is rotatably connected to the bottom plate via a rotating shaft. The end of the second triangular plate away from the auxiliary rotating plate causes the telescopic plate to move away from the second side plate while rotating, causing the first spring to undergo elastic deformation. The torque generated by the torsion spring is much greater than the force required for the first spring to undergo elastic deformation, which helps the second side plate and the bottom plate to be in the same plane, reducing the storage space. When the first and second top covers are closed, the rotation of the first top cover drives the locking component to rotate, and the locking component locks the first and second top covers to prevent the shared express box from unfolding automatically. At the same time, through the rotation unfolding device, telescopic unfolding device, main cover device and auxiliary cover device, the shared express box can be quickly unfolded or closed, which helps to save storage space.

[0024] 2. Move the irregularly shaped sliding plate of the locking component towards the second spring. The second spring undergoes elastic deformation. Close the first and second top covers. Release the irregularly shaped sliding plate. The elastically deformed second spring returns to its original state. Push the irregularly shaped sliding plate back to its initial position. The irregularly shaped sliding plate enters the slot of the second top cover, locking the first and second top covers. The label cable tie is set in the opening on the upper side of the irregularly shaped sliding plate and the upper side of the first top cover, which is conducive to quickly locking the shared express box and can also quickly identify whether the shared express box has been opened.

[0025] 3. Loosen the nut and move the sliding plate to the appropriate position. The movement of the sliding plate will cause the left side of the first rotating bracket to slide on the sliding plate. The second rotating bracket will rotate as it moves with the first rotating bracket. Tighten the nut to fix the first rotating bracket on the sliding plate. The first rotating bracket and the second rotating bracket will fix the sliding plate. The partition is fixedly installed on the end of the sliding plate near the nut. The partition is fixed, which restricts the internal space of the shared express box to a suitable size. This allows for adjustment of the space size according to different items and reduces the amount of filler material consumed to fix the items. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to embodiments.

[0039] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0040] Example 1: In some examples, please refer to Figures 1-8 A shared express box opening and closing structure includes a base plate 1. Rotating unfolding devices 2 are installed on both the left and right sides of the base plate 1, and telescopic unfolding devices 3 are installed on both the front and rear sides of the base plate 1. Adjacent telescopic unfolding devices 3 and rotating unfolding devices 2 are rotatably connected by a pivot. A secondary cover device 4 is installed at the end of the front telescopic unfolding device 3 away from the base plate 1, and a main cover device 5 is installed at the end of the rear telescopic unfolding device 3 away from the base plate 1. Space adjustment devices 6 are provided on both the rotating unfolding device 2 on the left side of the base plate 1 and the telescopic unfolding device 3 on the rear side of the base plate 1. The space adjustment device 6 includes an adjustment mechanism and partitions 61. Adjustment mechanisms are installed on both the rotating unfolding device 2 on the left side of the base plate 1 and the telescopic unfolding device 3 on the rear side of the base plate 1. The partitions 61 are fixedly installed at the end of the adjustment mechanism near the base plate 1. Multiple slots are provided on both partitions 61, allowing them to interlock and move to adjust the size of the internal space of the shared express box, avoiding the use of excessive filler to secure items.

[0041] The internal space of the shared express box is adjusted by the space adjustment device 6 to reduce the filling material consumed by fixing items. Items are placed inside the shared express box. The shared express box is closed by rotating the unfolding device 2 and the telescopic unfolding device 3. Then the shared express box is closed by closing the secondary cover device 4 and the main cover device 5.

[0042] The rotating and unfolding device 2 includes: a first side plate 21, a main rotating plate 22, and a connecting assembly. The first side plate 21 is rotatably connected to the left and right sides of the base plate 1 via a rotating shaft. A torsion spring is provided on the rotating shaft of the first side plate 21. One end of the torsion spring is fixedly installed on the base plate 1, and the other end of the torsion spring is fixedly installed on the first side plate 21. The two main rotating plates 22 are rotatably connected to the front and rear sides of the first side plate 21 via rotating shafts, respectively. The connecting assembly is installed at the end of the main rotating plate 22 away from the first side plate 21.

[0043] The torsion spring that has undergone elastic deformation returns to its original state, causing the first side plate 21 to rotate. The rotation of the first side plate 21 initially unfolds the first side plate 21. The rotation of the first side plate 21 causes the main rotating plate 22 to rotate. The rotation of the main rotating plate 22 causes the connecting assembly to rotate, which is beneficial for the initial unfolding of the first side plate 21.

[0044] The connecting assembly includes: a first triangular plate 23, a secondary rotating plate 24, and a second triangular plate 25. The first triangular plate 23 is rotatably connected to the end of the main rotating plate 22 away from the first side plate 21 via a rotating shaft. The secondary rotating plate 24 is rotatably connected to the end of the first triangular plate 23 away from the main rotating plate 22 via a rotating shaft. The second triangular plate 25 is rotatably connected to the end of the secondary rotating plate 24 away from the first triangular plate 23 via a rotating shaft.

[0045] The rotation of the main rotating plate 22 drives the first triangular plate 23 to rotate, the rotation of the first triangular plate 23 drives the secondary rotating plate 24 to rotate, and the rotation of the secondary rotating plate 24 drives the second triangular plate 25 to rotate, thus fully unfolding the first side plate 21. This helps the first side plate 21 and the base plate 1 to be in the same plane, reducing the storage space.

[0046] The telescopic deployment device 3 includes a second side plate 31 and a telescopic assembly. The second side plate 31 is rotatably connected to the front and rear sides of the base plate 1 via a rotating shaft, and the telescopic assembly is installed on the left and right sides of the second side plate 31.

[0047] The torsion spring that has undergone elastic deformation returns to its original state, causing the second side plate 31 to rotate. The rotation of the second side plate 31 initially unfolds the second side plate 31, and the rotation of the second side plate 31 causes the telescopic assembly to rotate, which is beneficial for the initial unfolding of the second side plate 31.

[0048] The telescopic assembly includes a telescopic plate 32 and a first spring 33. The telescopic plate 32 is slidably connected to the left and right sides of the second side plate 31. A plurality of first springs 33 are disposed inside the second side plate 31. One end of the first spring 33 is fixedly connected to the second side plate 31, and the other end of the first spring 33 is fixedly connected to the end of the telescopic plate 32 near the second side plate 31. The end of the telescopic plate 32 away from the second side plate 31 is rotatably connected to the end of the second triangular plate 25 away from the auxiliary rotating plate 24 via a rotating shaft.

[0049] The rotation of the second side plate 31 drives the telescopic plate 32 to rotate. The end of the telescopic plate 32 away from the second side plate 31 is rotatably connected to the end of the second triangular plate 25 away from the auxiliary rotating plate 24 through a pivot. This causes the telescopic plate 32 to rotate and move away from the second side plate 31, causing the first spring 33 to undergo elastic deformation. The torque generated by the torsion spring is much greater than the force required for the first spring 33 to undergo elastic deformation, which helps the second side plate 31 and the bottom plate 1 to be in the same plane, thus reducing the storage space.

[0050] The main cover device 5 includes a first upper cover 51 and a locking assembly. The first upper cover 51 is rotatably connected to the second side plate 31 of the rear telescopic unfolding device 3 via a rotating shaft. A torsion spring is provided on the rotating shaft of the first upper cover 51. One end of the torsion spring is fixedly connected to the second side plate 31, and the other end of the torsion spring is fixedly connected to the first upper cover 51. The locking assembly is installed on the first upper cover 51. The secondary cover device 4 includes a second upper cover. The second upper cover is rotatably connected to the second side plate 31 of the front telescopic unfolding device 3 via a rotating shaft. A torsion spring is provided on the rotating shaft of the second upper cover. One end of the torsion spring is fixedly connected to the second side plate 31, and the other end of the torsion spring is fixedly connected to the second upper cover. The second upper cover has a slot for accommodating the locking assembly. The first upper cover 51 and the second upper cover have protrusions 7 on both sides for locking the first side plate 21 and the second side plate 31 inward to prevent them from rotating.

[0051] When the first and second covers are closed, the first cover 51 rotates, causing the locking component to rotate. The locking component locks the first and second covers, preventing the shared express box from unfolding automatically. At the same time, by rotating the unfolding device 2, the telescopic unfolding device 3, the main cover device 5, and the secondary cover device 4, the shared express box can be quickly unfolded or merged, which helps save storage space.

[0052] Example 2: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, the locking assembly includes: a shaped sliding plate 52, a second spring 53, and a label cable tie 54. The shaped sliding plate 52 is slidably connected to the first upper cover 51. One end of the second spring 53 is fixedly connected to the first upper cover 51, and the other end of the second spring 53 is fixedly connected to the shaped sliding plate 52. Openings are provided on the upper side of the shaped sliding plate 52 and the upper side of the first upper cover 51. The label cable tie 54 is disposed in the opening. The label cable tie 54 is a commercially available technology and can be a label cable tie 54 produced by Dongguan Qiaoxin Hardware & Plastic Products Co., Ltd.

[0053] The irregularly shaped sliding plate 52 of the locking component is moved towards the second spring 53, causing the second spring 53 to undergo elastic deformation, closing the first and second upper covers 51 and releasing the irregularly shaped sliding plate 52. The elastically deformed second spring 53 returns to its original state, pushing the irregularly shaped sliding plate 52 back to its initial position. The irregularly shaped sliding plate 52 enters the slot of the second upper cover, locking the first and second upper covers 51. The label cable tie 54 is set in the openings on the upper side of the irregularly shaped sliding plate 52 and the upper side of the first upper cover 51, which facilitates quick locking of the shared express box and can quickly identify whether the shared express box has been opened.

[0054] The adjustment mechanism includes: a first rotating bracket 62, a second rotating bracket 63, a threaded rod 64, a sliding plate 65, and a nut 66. The right side of the first rotating bracket 62 is rotatably connected to the side wall of the second side plate 31 via a rotating shaft. The middle side of the second rotating bracket 63 is rotatably connected to the middle side of the first rotating bracket 62 via a rotating shaft. The left side of the second rotating bracket 63 is slidably connected to the side wall of the second side plate 31 via a rotating shaft. The threaded rod 64 is fixedly installed on the left side of the first rotating bracket 62. The sliding plate 65 is located on the front side of the second side plate 31. The left side of the first rotating bracket 62 is slidably connected to the sliding plate 65 via the threaded rod 64. The right side of the second rotating bracket 63 is rotatably connected to the right side of the second side plate 31 via a rotating shaft. The nut 66 is threadedly connected to the upper side of the threaded rod 64. The partition plate 61 is fixedly installed on the end of the sliding plate 65 near the nut 66.

[0055] Loosen nut 66, move sliding plate 65 to a suitable position. The movement of sliding plate 65 causes the left side of first rotating bracket 62 to slide on sliding plate 65. Second rotating bracket 63 rotates while moving with first rotating bracket 62. Tighten nut 66 to fix first rotating bracket 62 on sliding plate 65. The fixation of first rotating bracket 62, together with second rotating bracket 63, fixes sliding plate 65. Partition 61 is fixedly installed on the end of sliding plate 65 near nut 66. The fixation of partition 61 restricts the internal space of shared express box to a suitable size, which is conducive to adjusting the space size according to different items and reducing the filling material consumed to fix the items.

[0056] Example 3: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, a method for opening and closing a shared express box includes the following steps:

[0057] Step 1: Rotate the first side plate 21 and the second side plate 31. The torsion springs on the shafts of the first side plate 21 and the second side plate 31 undergo elastic deformation. The rotation of the first side plate 21 drives the main rotating plate 22 to rotate. The rotation of the main rotating plate 22 drives the first triangular plate 23 to rotate. The rotation of the first triangular plate 23 drives the auxiliary rotating plate 24 to rotate. The rotation of the auxiliary rotating plate 24 drives the second triangular plate 25 to rotate. The first side plate 21 is rotated to be perpendicular to the bottom plate 1. The rotation of the second side plate 31 drives the telescopic plate 32 to rotate. While rotating, the telescopic plate 32 moves away from the second side plate 31, causing the first spring 33 to undergo elastic deformation. The second side plate 31 is rotated to be perpendicular to the bottom plate 1.

[0058] Step 2: Loosen nut 66, move sliding plate 65 to a suitable position. The movement of sliding plate 65 causes the left side of first rotating bracket 62 to slide on sliding plate 65. Second rotating bracket 63 rotates while moving with first rotating bracket 62. Tighten nut 66 to fix first rotating bracket 62 on sliding plate 65. The fixation of first rotating bracket 62, together with second rotating bracket 63, fixes sliding plate 65. Partition 61 is fixedly installed on the end of sliding plate 65 near nut 66. The fixation of partition 61 restricts the internal space of shared express box to a suitable size, while preventing first side plate 21 and second side plate 31 from rotating at too many angles.

[0059] Step 3: Move the irregularly shaped sliding plate 52 of the locking component towards the second spring 53. The second spring 53 undergoes elastic deformation, closing the first and second upper covers. Release the irregularly shaped sliding plate 52, and the elastically deformed second spring 53 returns to its original state. Push the irregularly shaped sliding plate 52 back to its initial position, and the irregularly shaped sliding plate 52 enters the slot of the second upper cover, locking the first and second upper covers. The label cable tie 54 is set in the opening on the upper side of the irregularly shaped sliding plate 52 and the upper side of the first upper cover 51, locking the shared express box and quickly identifying whether the shared express box has been opened.

[0060] Step 4: When opening the shared express box, cut the label cable tie 54, move the irregularly shaped sliding plate 52 of the locking component towards the second spring 53, open the first top cover 51 and the second top cover, release the irregularly shaped sliding plate 52, the torsion spring that has undergone elastic deformation returns to its original state, causing the first side plate 21 and the second side plate 31 to rotate, loosen the nut 66, move the sliding plate 65 to the initial position, the first side plate 21 and the second side plate 31 rotate, the shared express box will be fully unfolded, and the items can be taken out.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

9. A method for opening and closing the shared express box as described in claim 8, characterized in that, Includes the following steps: Step 1: Rotate the first side plate (21) and the second side plate (31). The torsion springs of the first side plate (21) and the second side plate (31) undergo elastic deformation. The rotation of the first side plate (21) drives the main rotating plate (22) to rotate. The rotation of the main rotating plate (22) drives the first triangular plate (23) to rotate. The rotation of the first triangular plate (23) drives the auxiliary rotating plate (24) to rotate. The rotation of the auxiliary rotating plate (24) drives the second triangular plate (25) to rotate. Rotate the first side plate (21) to be perpendicular to the bottom plate (1). The rotation of the second side plate (31) drives the telescopic plate (32) to rotate. While rotating, the telescopic plate (32) moves away from the second side plate (31), causing the first spring (33) to undergo elastic deformation. Rotate the second side plate (31) to be perpendicular to the bottom plate (1). Step 2: Loosen the nut (66), move the sliding plate (65) to the appropriate position. The movement of the sliding plate (65) causes the left side of the first rotating bracket (62) to slide on the sliding plate (65). The second rotating bracket (63) rotates while following the movement of the first rotating bracket (62). Tighten the nut (66) so that the first rotating bracket (62) is fixed on the sliding plate (65). The first rotating bracket (62) is fixed and cooperates with the second rotating bracket (63) to fix the sliding plate (65). The partition (61) is fixedly installed on the end of the sliding plate (65) near the nut (66). The partition (61) is fixed so that the internal space of the shared express box is limited to a suitable size, and at the same time, the first side plate (21) and the second side plate (31) do not rotate at too many angles. Step 3: Move the irregularly shaped sliding plate (52) of the locking component toward the direction of the second spring (53). The second spring (53) undergoes elastic deformation, closes the first cover (51) and the second cover, releases the irregularly shaped sliding plate (52), and the elastically deformed second spring (53) returns to its original state. Push the irregularly shaped sliding plate (52) back to its initial position, and the irregularly shaped sliding plate (52) enters the slot of the second cover, locking the first cover (51) and the second cover. The label cable tie (54) is set in the opening on the upper side of the irregularly shaped sliding plate (52) and the upper side of the first cover (51), locking the shared express box and quickly identifying whether the shared express box has been opened. Step 4: When you want to unpack the shared express box, cut the label strap (54), move the irregularly shaped sliding plate (52) of the locking component towards the second spring (53), open the first top cover (51) and the second top cover, loosen the irregularly shaped sliding plate (52), the torsion spring that has undergone elastic deformation returns to its original state, causing the first side plate (21) and the second side plate (31) to rotate, loosen the nut (66), move the sliding plate (65) to the initial position, the first side plate (21) and the second side plate (31) rotate, the shared express box will be fully unfolded, and you can take out the items.
