Embodiment

[0019] A fragile item transportation device with a protection function, as Figures 1-4 and Figure 7 shown, includes a U - shaped protective box 1; It also includes a first multi-stage electric push rod 101, a connecting block 102, a second multi-stage electric push rod 103, a mounting frame 104, a third multi-stage electric push rod 105, a connecting rack 106, a plug rod 107, a fixing airbag 108, a clamping airbag 110 and a first limiting airbag 201; Two first multi-stage electric push rods 101 are bolted to the protective box 1; The telescopic end of each first multi-stage electric push rod 101 is connected with a connecting block 102; A second multi-stage electric push rod 103 is bolted to each connecting block 102; The telescopic ends of the two second multi-stage electric push rods 103 are jointly bolted to a mounting frame 104; Two third multi-stage electric push rods 105 are bolted to the mounting frame 104; The telescopic ends of the two third multi-stage electric push rods 105 are jointly bolted to a connecting rack 106. The connecting rack 106 is located above the mounting frame 104, and the third multi-stage electric push rod 105 penetrates upward through the connecting block 102; A plug rod 107 is arranged on the lower side of the connecting rack 106; A circular through hole for avoiding the plug rod 107 is formed in the mounting frame 104; Three fixing airbags 108 are arranged at the lower part of the plug rod 107; Four clamping airbags 110 are connected in the mounting frame 104; Four first limiting airbags 201 are arranged on the two side walls of the protective box 1.

[0020] It also includes an annular airbag 202 arranged on the inner bottom surface of the protective box 1. A circular groove is formed on the inner bottom surface of the protective box 1, and the annular airbag 202 is arranged in the circular groove; The annular airbag 202 is used for shock absorption.

[0021] In order to better protect the porcelain bottle 10, a plurality of annular airbags 202 are arranged, and all the annular airbags 202 are communicated with each other through hoses.

[0022] The connecting block 102 is arranged in an L shape and is slidably connected with the protective box 1, so that when the first multi-stage electric push rod 101 pushes the porcelain bottle 10 away from the protective box 1 through the connecting block 102, a part of the connecting block 102 is still in contact with the protective box 1, avoiding that the parts connected to the connecting block 102 and the weight after the porcelain bottle 10 are all borne by the first multi-stage electric push rod 101 and ensuring the stable use of the first multi-stage electric push rod 101.

[0023] It also includes a protective airbag 109 fixedly connected to the mounting frame 104. The protective airbag 109 is annular, and the protective airbag 109 is used to make soft contact with the upper end of the porcelain bottle 10 instead of the mounting frame 104.

[0024] The working process of this fragile item transportation device with a protective function is as follows: It is pre - stated that: This invention is mainly used as a transfer box and can be carried on an external transportation device. Driven by the external transportation device, this invention moves to transport and transfer the porcelain bottle 10. The main purpose of this invention is to provide protection and auxiliary functions during the transportation and transfer of the porcelain bottle 10; there is a battery and multiple [components] on the protection box 1 to supply power to the electrical components in this invention and supply gas to the airbag structure in this invention; taking Figure 1 as a reference, the side where the label of the protection box 1 is located is the left, and the side where the label of the porcelain bottle 10 is located is the rear.

[0025] Before transferring the porcelain bottle 10, first, manually drive this invention to the loading point by an external transportation device (transfer vehicle). Then, manually place the porcelain bottle 10 into the protection box 1 and adjust the position of the porcelain bottle 10 so that the mouth of the porcelain bottle 10 is directly opposite to the insertion rod 107. Then, control the micro - air pump to supply gas to the first limit airbag 201 to clamp and fix the body of the porcelain bottle 10. It should be noted that: the initial state of the third multi - stage electric push rod 105 is an extended state, and the initial state of the second multi - stage electric push rod 103 is a contracted state; then, drive the parts connected to it downward by the third multi - stage electric push rod 105 so that the insertion rod 107 is inserted into the porcelain bottle 10 through the mouth of the porcelain bottle 10. Then, inflate the fixed airbag 108 through the micro - air pump inside the insertion rod 107, forcing the three fixed airbags 108 to expand and contact the inner wall of the porcelain bottle 10. Then, drive the mounting frame 104 and the parts on it downward by the second multi - stage electric push rod 103 until the protection airbag 109 on the mounting frame 104 contacts the upper end of the porcelain bottle 10. Let the protection airbag 109 replace the mounting frame 104 to make soft contact with the upper end of the porcelain bottle 10 to avoid scratching the upper end surface of the porcelain bottle 10. Then, inflate the clamping airbag 110 through the micro - air pump on the mounting frame 104 to clamp and fix the outer side of the mouth of the porcelain bottle 10; thus, the porcelain bottle 10 is fixed and restricted by the fixed airbag 108, the protection airbag 109, the clamping airbag 110 and the first limit airbag 201 to prevent the porcelain bottle 10 from shaking and toppling during transportation, resulting in damage to the porcelain bottle 10; here it is stated that the external transportation device can install or support multiple of this invention at the same time to transport multiple porcelain bottles 10 simultaneously; after the porcelain bottle 10 is placed in each of this invention on the external transportation device, the external transportation device carries this invention and the porcelain bottle 10 to the packing area for packing work.

[0026] Here it is stated that after the external transportation device carries this invention and the porcelain bottle 10 to the packing area, deflate the fixed airbag 108, the clamping airbag 110 and the first limit airbag 201 through the micro - air pump to release the fixation of the porcelain bottle 10. Then, drive the mounting frame 104 and the parts on it upward away from the porcelain bottle 10 by the second multi - stage electric push rod 103. Then, manually unload the porcelain bottle 10 for packing work. The packing work is: wrapping the porcelain bottle 10 with the packing box 11.

[0027] Further, during the process of placing the porcelain bottle 10, the mounting frame 104 and the parts thereon can be pushed forward by the first multi-stage electric push rod 101, so that the insertion rod 107 moves to directly above the bottle mouth of the porcelain bottle 10 to be placed. Then, repeat the above operations of fixing the airbag 108 and clamping the airbag 110 to fix the porcelain bottle 10, clamp the porcelain bottle 10 to be placed, and then drive the porcelain bottle 10 to move upward away from the ground (placement table) by the second multi-stage electric push rod 103 and the third multi-stage electric push rod 105 through the parts connected thereto. At the same time, drive the mounting frame 104 and the parts thereon to reset by the first multi-stage electric push rod 101, and then place the porcelain bottle 10 into the protection box 1. Then, drive the porcelain bottle 10 to move downward by the second multi-stage electric push rod 103 and the third multi-stage electric push rod 105 through the parts connected thereto, so that the porcelain bottle 10 is placed in the protection box 1. In this way, the automatic placement of the porcelain bottle 10 is realized without manual operation, reducing the workload of manual labor. Similarly, it can be known that when the porcelain bottle 10 needs to be unloaded for packing, the first multi-stage electric push rod 101, the second multi-stage electric push rod 103, the third multi-stage electric push rod 105 and other parts can also be cooperated to automatically perform the unloading operation of the porcelain bottle 10 without manual unloading operation.

[0028] During the transfer process, since the lower side of the porcelain bottle 10 is in hard contact with the lower part of the protection box 1, when the protection box 1 vibrates due to environmental factors such as the road surface during the transfer process, the lower part of the porcelain bottle 10 lacks buffering and is easily damaged. Therefore, when the porcelain bottle 10 is placed in the protection box 1, the bottom of the porcelain bottle 10 is in contact with the annular airbag 202, and the annular airbag 202 is used to support the porcelain bottle 10 instead of the bottom surface of the protection box 1, avoiding damage to the porcelain bottle 10 easily caused by environmental factors such as the road surface during the transfer process.

[0029] Further, a plurality of annular airbags 202 are provided to increase the supporting area of the porcelain bottle 10 and ensure the protection effect on the porcelain bottle 10. After the bottom of the porcelain bottle 10 is in contact with the annular airbag 202 and the upper part of the porcelain bottle 10 is fixed and restricted by the fixed airbag 108, the protection airbag 109 and the clamping airbag 110, the annular airbag 202 is inflated by the micro air pump built in the protection box 1, so that the annular airbag 202 expands. Since all the annular airbags 202 are connected to each other through hoses, the annular airbag 202 located at the bottom of the porcelain bottle 10 cannot expand due to being blocked by the porcelain bottle 10, and the annular airbags 202 located outside the bottom of the porcelain bottle 10 will expand upward and wrap around the outer peripheral surface of the lower side of the porcelain bottle 10. The annular airbag 202 wraps and fixes the lower part of the porcelain bottle 10 to prevent the lower part of the porcelain bottle 10 from shifting during the transfer process and improve the stability of the porcelain bottle 10 during the transfer process. At the same time, by providing a plurality of annular airbags 202, porcelain bottles 10 of different sizes can be supported and restricted, improving the applicability of the present invention. Embodiment

[0030] Based on Embodiment 1, as Figure 2 、 Figure 3 and Figures 5-8 shown, it further includes a U-shaped frame 304 connected to the protective box 1; two sliding grooves 4001 are opened on the protective box 1; an electric slider 4002 is arranged on each sliding groove 4001; both electric sliders 4002 are bolted to the U-shaped frame 304; a second limiting airbag 308 is arranged on each of the two side walls of the U-shaped frame 304; a supporting part 30401 is arranged at the lower part of the U-shaped frame 304; a U-shaped mounting frame 305 is bolted to the front side of the protective box 1; a fourth multi-stage electric push rod 306 is arranged on the U-shaped mounting frame 305; a push plate 307 is arranged at the telescopic end of the fourth multi-stage electric push rod 306.

[0031] In order to increase the friction between the first limiting airbag 201 and the object to be fixed, a number of bumps are arranged on the clamping surface of each first limiting airbag 201.

[0032] It further includes a sponge block 30701 fixed on the push plate 307. By contacting the porcelain bottle 10 through the sponge block 30701, it is avoided that the push plate 307 makes hard contact with the porcelain bottle 10 and scratches the porcelain bottle 10.

[0033] Two limiting grooves 1001 are opened on the protective box 1.

[0034] It further includes two rotating rods 301 fixed on the protective box 1; the other end of the rotating rod 301 is connected to a mounting plate 303, and all the first limiting airbags 201 are arranged on the corresponding mounting plates 303; two DD motors 302 are fixed on the protective box 1, and the output end of the DD motor 302 is fixed to the corresponding rotating rod 301.

[0035] After the external transportation device carries the present invention and the porcelain bottle 10 to the packing area, first, the first limiting airbag 201 is deflated through the micro air pump, then the mounting frame 104 and the parts thereon are driven to move upward by the second multi-stage electric push rod 103, and then the connecting block 102, the mounting frame 104 and the parts thereon are driven to move forward by the first multi-stage electric push rod 101, so that the lower side of the porcelain bottle 10 is moved above the supporting part 30401 on the U-shaped frame 304. Then, the mounting frame 104 and the parts thereon are driven to move downward by the second multi-stage electric push rod 103, and the porcelain bottle 10 is placed on the supporting part 30401 on the U-shaped frame 304. Then, the fixing airbag 108 and the clamping airbag 110 are deflated through the micro air pump to release the fixation of the upper part of the porcelain bottle 10. During this process, the porcelain bottle 10 is fixed by inflating the second limiting airbag 308 with the micro air pump on the U-shaped frame 304, as Figure 8As shown, the porcelain bottle 10 is stably supported on the support portion 30401 of the U-shaped frame 304. After the fixing airbag 108 and the clamping airbag 110 release the fixation of the porcelain bottle 10, the second multi-stage electric push rod 103 drives the mounting frame 104 and the parts thereon to move upward away from the porcelain bottle 10.

[0036] Then, the micro air pump deflates the annular airbag 202 on the protection box 1, and then the packing box 11 is manually placed into the protection box 1 with the accommodating cavity facing the porcelain bottle 10. Then, the micro air pump supplies air to the first limiting airbag 201. As Figure 8 shown, the first limiting airbag 201 moves horizontally to fix the packing box 11 and correct the position of the packing box 11. Here, it should be noted that the upper side surface of the support portion 30401 is flush with the bottom surface of the accommodating cavity of the packing box 11. Then, the electric slider 4002 on the protection box 1 drives the U-shaped frame 304 and the parts thereon to move backward along the sliding groove 4001 until the support portion 30401 contacts the packing box 11. Then, the micro air pump deflates the second limiting airbag 308, and then the fourth multi-stage electric push rod 306 pushes the push plate 307 and the sponge block 30701 backward to push the porcelain bottle 10 into the accommodating cavity of the packing box 11, completing the automatic packing operation. Then, the manually packed packing box 11 is taken out. Compared with first taking out the porcelain bottle 10 from the protection box 1 and then manually performing the packing operation, and manually placing the packing box 11 into the corresponding protection box 1 in sequence, during the placement of the packing box 11, the protection box 1 with the previously placed packing box 11 automatically realizes the packing work of the porcelain bottle 10. After all the protection boxes 1 are placed with the packing boxes 11, the protection box 1 with the previously placed packing box 11 has completed the packing work of the porcelain bottle 10. At this time, the manually packed packing boxes 11 can be taken out in sequence. In this way, the continuity of the packing operation is improved, and the packing efficiency is improved. Here, it should be noted that before the manually packed packing box 11 is taken out, the electric slider 4002 drives the U-shaped frame 304 and the parts thereon to move backward along the sliding groove 4001 to reset, and then the micro air pump deflates the first limiting airbag 201 to stop fixing the packing box 11.

[0037] Furthermore, to avoid damage caused by the porcelain bottle 10 falling out of the packing box 11 easily during the process of manually removing the packing box 11 containing the porcelain bottle 10 from the protective box 1; therefore, before deflating the first limiting airbag 201 through the micro air pump to stop fixing the packing box 11, first drive the rotating rod 301 to rotate through the DD motor 302, so that the mounting plate 303 and the first limiting airbag 201 rotate counterclockwise with the right-to-left view as the reference, making the packing box 11 in an inclined state with the front lower and the rear higher. When manually removing the packing box 11, it is removed in an inclined state to avoid the problem that the porcelain bottle 10 is likely to fall out of the packing box 11 when the packing box 11 is removed in a vertical state; it should be noted here that the rotation angle of the mounting plate 303 is limited by the limiting groove 1001, so that when the DD motor 302 fails, the mounting plate 303 can be manually driven to rotate to an inclined state through the packing box 11.

[0038] The above are only examples of the present invention and are not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the prior art well-known to those skilled in the art.
