Description

Technical Field

[0001] The present invention relates to the technical field of express boxes, and in particular to a shared express box that is easy to carry and a method thereof. Background Art

[0002] Shared express boxes are an emerging environmentally friendly express solution used to reduce single-use express packaging. They are usually reusable packaging boxes that users can return to designated points after receiving the express delivery for others to use again. This approach not only reduces the waste of packaging materials, but also reduces the environmental burden of the logistics industry.

[0003] Chinese patent CN213110265U discloses a shared express box, including an outer box body, an outer cover, an inner cover, a connecting component and a password lock. The outer box body is open at the top, and a receiving cavity is arranged inside the outer box body. The outer box body is hinged to one side of the outer cover, and the inner cover covers the top opening of the outer box body. The connecting component and the password lock are both arranged on the inner cover. The inner cover is detachably connected to the outer box body through the connecting component, and the password lock is connected to the connecting component in a manner that the connecting component can be selectively locked, so that the shared express box can realize multiple recycling of the express box. However, the shared express box still has the following problems:

[0004] 1. The volume of the express box is fixed, but in actual use, different express parcels often have different sizes. If shared express boxes of various volumes are set up to deal with parcels of different sizes, it will not only increase production costs, but also reduce the efficiency of express packaging due to the specifications of the shared express boxes. At the same time, if there is a gap between the express box and the parcel it contains, the parcel will shake and move in the express box during transportation, causing damage to the parcel;

[0005] 2. The express boxes take up a lot of space. When you recycle the express boxes, they will take up a lot of space.

[0051] The openings of the upper cavity 15 and the lower cavity 25 are arranged opposite to each other, the upper box body 1 is slidably plugged into the inner side of the lower box body 2, and the outer wall of the upper side wall plate 12 of the upper box body 1 is fitted with the inner wall of the lower side wall plate 22 of the lower box body 2, so that the upper cavity 15 and the lower cavity 25 are combined to form a receiving cavity for receiving express delivery; the size of the receiving cavity is adjusted by pulling out the upper box body 1 and the lower box body 2, so that the box body can receive express delivery of different sizes;

[0052] A one-way adjustable telescopic locking mechanism 3 is provided between the upper box body 1 and the lower box body 2 to control the telescopic movement of the upper box body 1 in the lower box body 2;

[0053] The one-way adjustable telescopic locking mechanism 3 includes a one-way adjustment component 31, an unlocking component 32, a central control panel 33 and a shielding cover 34. A one-way adjustment component 31 is provided between the front ends of the upper box body 1 and the lower box body 2 to limit the upper box body 1 to slide only toward the inner side of the lower box body 2 to lock the box body.

[0054] The shielding cover 34 is fixedly mounted on the front of the lower box body 2, and a central control board 33 with an integrated NFC chip is arranged in the shielding cover 34. The shielding cover 34 is also provided with an unlocking component 32 for releasing the limiting effect of the one-way adjustment component 31 on the upper box body 1 to unlock the box body, and the unlocking component 32 is electrically connected to the central control board 33;

[0055] The top of the upper box body 1 and the bottom of the lower box body 2 are also provided with a stacking limiting mechanism 4 for making the combined stacking more stable when the boxes are stacked.

[0056] In the present invention, the express is placed in the lower cavity 25 of the lower box body 2, and then the upper box body 1 is inserted into the inner side of the lower box body 2 until the inner top of the upper box body 1 abuts against the top of the express, so that the upper box body 1 and the lower box body 2 cooperate to clamp and fix the express, and at the same time, the one-way adjustment component 31 limits the movement of the upper box body 1, so that the upper box body 1 can no longer extend from the lower box body 2, thereby achieving the locking effect of the box body; through the joint action of the upper box body 1, the lower box body 2 and the one-way adjustment component 31, the box body is not only easy to operate, but also simple and efficient to lock, and can be applied to expresses of different sizes, reducing the space occupied by the box body when loading the express, and can also tightly fix the express, avoid the express shaking in the box body during transportation, and reduce the possibility of damage to the express;

[0057] When the boxes are stacked, the stacking limiting mechanism 4 allows the adjacent boxes to be mutually limited, thereby increasing the stability of the stacked boxes and preventing the stacked boxes from tipping over or becoming scattered due to a slight collision.

[0058] When the recipient gets the box, after connecting it to the central control board 33 through the Internet of Things device, the unlocking component 32 controls the one-way adjustment component 31 to release the limiting effect on the upper box body 1. The recipient can take the upper box body 1 out of the lower box body 2 to take the express away. The pickup operation is simple and convenient, and the express is safely protected.

[0059] The one-way adjustment component 31 includes a ratchet bar 311, a through slot 312 and a clamping block 313. The ratchet bar 311 is fixedly installed at the front end of the upper box body 1, and a through slot 312 is provided at the front end of the lower box body 2. One end of the clamping block 313 is rotatably connected to the inner wall of the through slot 312 through a rotating shaft, and the other end of the clamping block 313 is clamped with the ratchet bar 311, so that the upper box body 1 can only slide toward the inner side of the lower box body 2; a torsion spring 314 is sleeved on the rotating shaft of the clamping block 313, and the two ends of the torsion spring 314 are respectively fixedly connected to the clamping block 313 and the inner wall of the through slot 312, so that the clamping block 313 is always against the ratchet bar 311.

[0060] The unlocking assembly 32 includes a shifting block 321, a micro motor 322 and a crank 323. The shifting block 321 is fixedly connected to the clamping block 313 to form a V-shaped structure, so that the shifting block 321 and the clamping block 313 rotate synchronously; the micro motor 322 is fixedly connected to the lower box body 2, and the output end of the micro motor 322 is fixedly installed with a crank 323 for shifting the shifting block 321; the micro motor 322 is electrically connected to the central control board 33;

[0061] In the present invention, when the upper box body 1 is inserted into the inner side of the lower box body 2, the ratchet bar 311 of the upper box body 1 contacts the shift block 321, and the clamping block 313 always abuts against the clamping block 313 under the action of the torsion spring 314. When the upper box body 1 slides into the inner side of the lower box body 2, the clamping block 313 slides on the ratchet bar 311. When the upper box body 1 moves to the outer side of the lower box body 2, the clamping block 313 clamps the ratchet bar 311 to block the movement of the upper box body 1, thereby realizing the unidirectional movement of the upper box body 1.

[0062] The upper box body 1 is continuously pressed down until the inner top of the upper box body 1 abuts against the express in the accommodating chamber, so that the upper box body 1 and the lower box body 2 cooperate to clamp and fix the express, and the box body can stably load the express; when the recipient needs to pick up the express, the Internet of Things device is connected to the central control board 33 for identity authentication, and the micro motor 322 is controlled to drive the crank 323 to rotate. The crank 323 drives the shift block 321 to make the card block 313 and the shift block 321 rotate synchronously around the rotating shaft, so that the card block 313 is disengaged from the ratchet bar 311, thereby releasing the limiting effect on the upper box body 1, and the recipient can smoothly pull out the upper box body 1 to open the box body and take out the express, which is not only convenient to operate but also highly safe.

[0063] In some embodiments, Figure 5 and Figure 6 As shown, the upper side wall plate 12 is hinged to the upper base plate 11 through a hinge, and the hinge is located on the outer side of the upper base plate 11 so that the upper side wall plate 12 in the folded state can rotate to the inner side of the upper box body 1; when the upper box body 1 is in the folded state, the upper side wall plate 12 is parallel to the upper base plate 11, so that the upper box body 1 is easy to store and carry; by closing the upper side wall plate 12 inward until the upper side wall plate 12 is erected, the upper box body 1 can be unfolded and used, and the upper side wall plate 12 is blocked and restricted by the upper base plate 11 so that the rotation range of the upper side wall plate 12 is zero to ninety degrees;

[0064] The upper side wall panels 12 on the left, right, front and rear sides of the upper base plate 11 are respectively provided as the first upper side wall panel 121, the second upper side wall panel 122, the third upper side wall panel 123 and the fourth upper side wall panel 124. The first upper side wall panel 121 and the second upper side wall panel 122 are arranged opposite to each other. When the upper box body 1 is unfolded, the first upper side wall panel 121 and the second upper side wall panel 122 are erected first, and then the third upper side wall panel 123 and the fourth upper side wall panel 124 are erected; upper clamping blocks 13 are symmetrically fixedly installed at both ends of the third upper side wall panel 123 and the fourth upper side wall panel 124; upper clamping grooves 14 that cooperate with the upper clamping blocks 13 are symmetrically opened at both ends of the first upper side wall panel 121 and the second upper side wall panel 122, and the upper clamping grooves 14 that cooperate with the upper clamping blocks 13 are used to make the upper side wall panels 12 more stable when erected;

[0065] In some embodiments, Figure 7 and Figure 8As shown, the lower side wall plate 22 is hinged to the lower base plate 21 by a hinge, and the hinge is arranged on the inner side of the lower base plate 21 so that the lower side wall plate 22 in the folded state can be rotated to the outer side of the lower box body 2; the folding effect of the lower box body 2 can be achieved by alternately rotating the four lower side wall plates 22 to the inner side of the lower box body 2, so that the lower box body 2 is easy to store and carry, and the lower side wall plates 22 have different heights, and the lower side wall plates 22 remain horizontal and will not tilt when fully folded and stored; the lower box body 2 can be unfolded and used by rotating the lower side wall plates 22 outward until the lower side wall plates 22 stand upright, and the lower side wall plates 22 are blocked and restricted by the lower base plate 21 so that the rotation range of the lower side wall plates 22 is zero to ninety degrees;

[0066] The lower side wall panels 22 on the left, right, front and rear sides of the lower side wall panel 22 are respectively set as the first lower side wall panel 221, the second lower side wall panel 222, the third lower side wall panel 223 and the fourth lower side wall panel 224, and the first lower side wall panel 221 and the second lower side wall panel 222 are arranged opposite to each other; when the lower box body 2 is unfolded, the third lower side wall panel 223 and the fourth lower side wall panel 224 are erected first, and then the first lower side wall panel 221 and the second lower side wall panel 222 are erected; the lower clamping blocks 23 are symmetrically fixedly installed at both ends of the third lower side wall panel 223 and the fourth lower side wall panel 224, and the lower clamping grooves 24 that cooperate with the lower clamping blocks 23 are symmetrically opened at both ends of the first lower side wall panel 221 and the second lower side wall panel 222, so that the lower side wall panel 22 is more stable when erected;

[0067] The upper side wall plate 12 rotates from the outside to the inside, and the upper side wall plate 12 in the vertical state is restricted by the upper base plate 11 and can only rotate outward, while the lower side wall plate 22 rotates from the inside to the outside, and the lower side wall plate 22 in the vertical state is restricted by the lower base plate 21 and can only rotate inward. Therefore, when the upper box body 1 is inserted into the lower box body 2, the upper side wall plate 12 and the lower base plate 21 restrict each other so that the upper side wall plate 12 and the lower side wall plate 22 can both stably maintain a vertical state to prevent the box body from deformation.

[0068] The box body is made of PVC plastic material, which is low in cost and light and strong.

[0069] Embodiment 2: In some embodiments, Figure 1-Figure 3 As shown, the stacking limiting mechanism 4 includes a vertical adjacent limiting component 41 and a horizontal adjacent limiting component 42. The vertical adjacent limiting component 41 is arranged at the top and bottom of the box body, and is used to limit the adjacent horizontal adjacent limiting components 42 stacked vertically; the horizontal adjacent limiting component 42 is arranged at the bottom of the box body, and is used to limit the adjacent horizontal adjacent limiting components 42 stacked horizontally;

[0070] The vertically adjacent limiting components 41 include pads 411 and grooves 412. Pads 411 are symmetrically fixedly installed at the left and right ends of the bottom of the lower box body 2. A rubber layer is provided on the pads 411 for anti-slip and vibration reduction. Grooves 412 for plugging with the pads 411 are symmetrically opened at the left and right ends of the top of the upper box body 1.

[0071] The horizontally adjacent limiting components 42 include a receiving groove 421, a limiting block 422 and a limiting groove 423. The left side and the rear side of the bottom of the lower box body 2 are provided with a receiving groove 421, and the limiting block 422 is rotatably installed in the receiving groove 421. The bottom of the lower box body 2 is provided with a limiting groove 423 on the opposite side of the receiving groove 421, which cooperates with the limiting block 422.

[0072] When the boxes are stacked vertically, the stability of the stacked boxes can be increased by plugging the pad 411 into the groove 412; when the boxes are stacked, the limit block 422 is rotated out of the accommodating groove 421, and the limit blocks 422 and limit grooves 423 of adjacent boxes are fixed together, thereby increasing the stability of the boxes placed in stacks.

[0073] A handle 5 is fixedly installed on the upper end of the upper box body 1, and a handle 5 is fixedly installed on both sides of the lower box body 2, which is convenient for users to carry the box body and is also conducive to controlling the insertion and extension of the upper box body 1 in the lower box body 2; the handle 5 is made of cloth bag material, has high strength and occupies little space.

[0074] Embodiment 3: In some embodiments, Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, a method for using a shared express box that is easy to carry includes the following steps:

[0075] Step 1: Rotate the upper side wall plate 12 of the upper box body 1 from the outside to the inside until the upper side wall plate 12 remains vertical so that the upper box body 1 is unfolded; rotate the lower side wall plate 22 of the lower box body 2 from the inside to the outside until the lower side wall plate 22 remains vertical so that the lower box body 2 is unfolded;

[0076] Step 2: Put the express to be delivered into the lower cavity 25 of the lower box body 2, and then insert the upper box body 1 into the inner side of the lower box body 2 until the inner top of the upper box body 1 abuts against the top of the express, so that the upper box body 1 and the lower box body 2 cooperate to clamp and fix the express;

[0077] Step 3: When the upper box body 1 slides toward the inner side of the lower box body 2, the block 313 slides on the ratchet bar 311, and the block 313 blocks the movement of the upper box body 1 by blocking the ratchet bar 311, thereby locking the box body;

[0078] Step 4: The boxes need to be stacked during delivery.
