DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

[0018] Most existing transport containers only use foam and some soft items to protect fragile items, and the cushioning and shock-absorbing capabilities of such protective media are average, that is, existing transport containers are difficult to effectively protect fragile items. At the same time, workers are required to fix fragile items before transportation, but the fixing efficiency is low and the fixing points are relatively single, making it difficult to fully protect fragile items during transportation.

[0019] Example 1: A multi-point fixed fragile goods transport container for logistics, such as Figure 1-Figure 4As shown, it includes a base frame 1, a accommodating shell 2 is fixedly connected to the left part of the upper side of the base frame 1, a hydraulic cylinder 3 is fixedly connected to the middle part of the upper side of the base frame 1, and an electric push rod 4 is fixedly connected to the middle front part of the upper side of the base frame 1. A accommodating cavity is arranged in the accommodating shell 2, and the accommodating cavity is used to place fragile items 101. The hydraulic cylinder 3 is slidably connected to a sliding rod 5 fixedly connected to the telescopic end of the electric push rod 4. A transmission medium is arranged between the hydraulic cylinder 3 and the sliding rod 5, and the transmission medium is hydraulic oil. A liquid separation shell 6 is fixedly connected to the lower side of the accommodating shell 2, and the liquid separation shell 6 is hollow. The first tube 7 is connected between the liquid separation shell 6 and the hydraulic cylinder 3, and the first tube 7 is provided with hydraulic oil. The housing shell 2 is fixed with four sliding shells 8 in an annular array, and the sliding shell 8 is provided with a first channel 801 and three second channels 802 arranged evenly in the vertical direction. The first channel 801 is provided with hydraulic oil, and the four first channels 801 are all located outside the twelve second channels 802, and the twelve second channels 802 are all located outside the housing cavity of the housing shell 2. Adjacent The three second channels 802 are all connected with the adjacent first channels 801, the liquid separation shell 6 and the four sliding shells 8 are fixedly connected and connected with the second tube 9 connected with the adjacent first channels 801, hydraulic oil is arranged in the second tube 9, four sliding plates 10 in a ring array are arranged in the accommodating shell 2, the four sliding plates 10 are located inside the four sliding shells 8, three evenly arranged first shells 11 are fixedly connected between the sliding shell 8 and the adjacent sliding plates 10, the first shell 11 is connected with the adjacent second channels 802, the second shell 12 is slidably connected in the first shell 11, and the fixing rod 13 is slidably connected in the second shell 12, and the fragile goods 101 are fixed at multiple points by twelve pairs of fixing rods 13 (the specific number here is for understanding only and is not a factor to limit the present invention), so as to improve the stability of the fragile goods 101 during transportation, and a blocking mechanism for allowing the three adjacent fixing rods 13 to extend out in sequence is commonly provided between the sliding shell 8 and the adjacent sliding plates 10.

[0020] like Figure 3 and Figure 4As shown, the blocking mechanism includes three blocking plates 1401 arranged evenly in vertical direction, and the three blocking plates 1401 are respectively slidably connected to the side of the adjacent first shell 11 close to the adjacent sliding shell 8, and the lower side of the blocking plate 1401 is an inclined surface, and the distance between the inclined surfaces on the blocking plates 1401 on the same horizontal plane gradually increases from bottom to top, which is used to change the blocking state of the blocking plate 1401 to the adjacent first shell 11, and a first elastic element 1402 is fixedly connected between the blocking plate 1401 and the adjacent first shell 11, and the first elastic element 1402 is made of elastic rubber material, and is used to reset the adjacent blocking plate 1401, and utilize the first elastic element 1402 to reset the adjacent blocking plate 1401. The elastic element 1402 exerts force on the adjacent blocking plates 1401, so that the blocking plates 1401 arranged up and down are opened in sequence from bottom to top, thereby gradually fixing the fragile item 101, thereby improving the stability when fixing it, and further improving the fixing effect. The sliding shell 8 is provided with three third channels 1403 arranged evenly in the vertical direction. The third channel 1403 is connected to the adjacent first shell 11. A one-way valve 1404 is installed at the connection between the first shell 11 and the adjacent third channel 1403. The flow direction of the one-way valve 1404 is from inside to outside. A filling component for filling the medium into the containing shell 2 is provided on the upper side of the base frame 1.

[0021] like Figure 1 , Figure 5 and Figure 6As shown, the filling component includes a storage shell 1501, which is fixed to the right part of the upper side of the base frame 1. A buffer medium is arranged in the storage shell 1501, and the buffer medium is water. The volume of the storage chamber in the storage shell 2 is smaller than the volume in the storage shell 1501, so that the buffer medium in the storage shell 1501 fills the storage chamber in the storage shell 2, and the ratio of the inner diameter of the storage shell 1501 to the diameter of the storage chamber of the storage shell 2 is greater than the ratio of the inner diameter of the hydraulic cylinder 3 to the sum of the inner diameters of the four first channels 801, so that the speed at which water fills the storage chamber in the storage shell 2 is greater than the speed at which the fixing rod 13 fixes the fragile item 101. The storage shell 1501 is slidably connected to a first L-shaped rod 1502 fixed to the sliding rod 5, and a fourth channel 1503 is arranged on the lower side of the storage shell 2. The fourth channel 1503 is a circular closed channel. A third tube 1504 fixedly connected to the containing shell 2 is connected between the four channels 1503 and the storage shell 1501. Four fourth tubes 1505 in a ring array are fixedly connected in the containing shell 2. The four fourth tubes 1505 are all connected to the fourth channels 1503. The four fourth tubes 1505 are all connected to the containing cavity of the containing shell 2. An insulating member 1506 is fixedly connected to the upper part of the containing shell 2. The insulating member 1506 is elastic plastic and is used to isolate the water in the containing cavity of the containing shell 2 and wrap the fragile item 101. The first L-shaped rod 1502 moves downward and presses the water in the storage shell 1501 into the containing cavity of the containing shell 2, and the water wraps the fragile item 101, so that the force that may cause local load on the fragile item 101 is evenly dispersed to the outside, thereby strengthening the protection of the fragile item 101 during transportation.

[0022] When the present invention is needed to transport fragile items 101 (fragile items 101 are art vases and the like, but not limited to art vases), the staff first places some foam inside the fragile items 101 to strengthen the protection of the fragile items 101 during transportation, and then the staff puts the fragile items 101 into the accommodating cavity of the accommodating shell 2, and then starts the electric push rod 4, the telescopic end of the electric push rod 4 starts to move downward, the telescopic end of the electric push rod 4 drives the sliding rod 5 to move downward together, the sliding rod 5 starts to squeeze the hydraulic oil in the hydraulic cylinder 3, the hydraulic oil in the hydraulic cylinder 3 enters the liquid separation shell 6 after passing through the first tube 7, and then the hydraulic oil in the liquid separation shell 6 enters the four second tubes 9 respectively, the hydraulic oil in the second tube 9 enters the adjacent first channel 801, and as the sliding rod 5 continues to move downward, the hydraulic oil in the first channel 801 The pressure of the hydraulic oil gradually increases and begins to squeeze the adjacent sealing plates 1401. Since the bottom sealing plate 1401 is subjected to the greatest pressure of the hydraulic oil, the four sealing plates 1401 on the bottom side begin to move upward first, and the sealing plate 1401 squeezes the adjacent first elastic element 1402. At the same time, the four sealing plates 1401 on the bottom side lose their sealing of the adjacent first shell 11. Then the hydraulic oil enters the adjacent first shell 11 through the four second channels 802 on the bottom side. Subsequently, the hydraulic oil that enters the first shell 11 begins to squeeze the adjacent fixing rods 13, and the four fixing rods 13 on the bottom side begin to move toward each other. When the fixing rods 13 move toward each other to the extreme position on the adjacent second shell 12, the fixing rods 13 drive the adjacent second shell 12 to move together until the fixing rods 13 move toward each other and contact the outside of the fragile product 101.

[0023] As the sliding rod 5 continues to move downward and the four fixing rods 13 on the lower side are limited by the fragile object 101, the pressure of the hydraulic oil on the four middle blocking plates 1401 begins to increase, and the four middle blocking plates 1401 begin to move upward and squeeze the adjacent first elastic elements 1402 until the four middle fixing rods 13 are in contact with the outside of the fragile object 101, and finally the four upper blocking plates 1401 move upward again, and the four upper fixing rods 13 are finally in contact with the outside of the fragile object 101, and the fragile object 101 is automatically fixed gradually from bottom to top by using several fixing rods 13, and finally the fragile object 101 is fixed at multiple points, so as to increase the stability of the fragile object 101 during the fixing process and the stability during subsequent transportation, strengthen the protection of the fragile object 101, and at the same time improve the fixing efficiency and effect of the fragile object 101, and reduce the operating steps of the staff.

[0024] In order to improve the stability of the fragile product 101 during transportation, the accommodating cavity of the accommodating shell 2 is filled with water and the fragile product 101 is fully wrapped and protected to prevent the fragile product 101 from being broken due to excessive local force on the fragile product 101 due to the inertia generated by turning and braking during transportation. The specific steps are as follows: when the sliding rod 5 moves downward, the sliding rod 5 drives the first L-shaped rod 1502 to move downward together, and the first L-shaped rod 1502 begins to squeeze the water in the storage shell 1501, and the water in the storage shell 1501 begins to enter the fourth channel 1503 through the third tube 1504, and the water in the fourth channel 1503 then enters the accommodating cavity of the accommodating shell 2 through the adjacent fourth tubes 1505. As the first L-shaped rod 1502 continues to move downward, the liquid level in the accommodating chamber of the accommodating shell 2 continues to rise, and the rising water in the liquid level lifts up the isolation piece 1506 and prompts the isolation piece 1506 to wrap the fragile item 101 until the water fills the accommodating chamber of the accommodating shell 2 and the isolation piece 1506 completely wraps the fragile item 101. Then the staff turns off the electric push rod 4, so that when passing through a curve or braking during the subsequent transportation process, the water in the accommodating chamber of the accommodating shell 2 will evenly apply the force that may act on the local part of the fragile item 101 to its outside, thereby increasing the force area of ​​the fragile item 101 and reducing the local force on the fragile item 101 (the same as holding an egg with bare hands), thereby strengthening the protection of the fragile item 101 during transportation.

[0025] Since the ratio of water discharged from the storage shell 1501 to the water flowing into the accommodating chamber on the accommodating shell 2 per unit time is greater than the ratio of the hydraulic oil discharged from the hydraulic cylinder 3 to the hydraulic oil flowing into the first channel 801, the rising speed of the liquid level in the accommodating shell 2 is greater than the moving speed of the adjacent fixing rod 13. Therefore, when the fixing rod 13 contacts the fragile item 101, the insulating member 1506 has wrapped the area on the fragile item 101 to be fixed and fits tightly therewith under the action of water, thereby preventing the fixing rod 13 from scratching the insulating member 1506, thereby affecting the protection effect on the fragile item 101.

[0026] After the fragile object 101 is transported, the staff starts the electric push rod 4, and the telescopic end of the electric push rod 4 starts to move upward, and the telescopic end of the electric push rod 4 drives the sliding rod 5 to move upward together, and the sliding rod 5 drives the first L-shaped rod 1502 to move upward together, and the sliding rod 5 and the first L-shaped rod 1502 start to extract the hydraulic oil in the first tube 7 and the water in the third tube 1504 respectively. At this time, the pressure of the hydraulic oil in the first channel 801 starts to decrease from the top, that is, the four blocking plates 1401 on the upper side start to move downward under the elastic force of the adjacent first elastic elements 1402 until the four first elastic elements 1402 on the upper side are closed. The elastic element 1402 is fully reset. At this time, the four sealing plates 1401 on the upper side respectively seal the adjacent first shells 11, and the hydraulic oil in the upper first shell 11 begins to enter the adjacent third channel 1403 through the adjacent one-way valve 1404 under the action of negative pressure, and then enters the adjacent first channel 801, and finally enters the hydraulic cylinder 3. During this process, the four second shells 12 and the four fixing rods 13 on the upper side all move outward until they are fully reset. As the pressure of the hydraulic oil in the first channel 801 gradually decreases, the middle and lower second shells 12 and the parts thereon are gradually reset in turn until all parts are reset.

[0027] During the resetting process of the second shell 12 and the parts thereon, the liquid level of the water in the accommodating chamber on the accommodating shell 2 gradually drops, that is, the support for the isolation piece 1506 and the wrapping of the fragile item 101 are gradually lost, until all the water in the accommodating chamber on the accommodating shell 2 enters the storage shell 1501, and then the staff can close the electric push rod 4.

[0028] In Example 1, "the containing shell 2 and the sliding shell 8 are fixedly connected, and the containing shell 2 and the sliding plate 10 are fixedly connected", while in Example 2, "the containing shell 2 and the sliding shell 8 are slidably connected, and the containing shell 2 and the sliding plate 10 are slidably connected", thereby changing the position of the fragile item 101 in the containing cavity on the containing shell 2, thereby further strengthening the protection of the fragile item 101.

[0029] Embodiment 2: Based on embodiment 1, Figure 5-Figure 7As shown, it also includes a blocking mechanism for blocking the containing shell 2, the blocking mechanism is arranged on the upper side of the base frame 1, the four sliding shells 8 and the four sliding plates 10 are all slidably connected to the containing shell 2, the blocking mechanism includes a second L-shaped rod 1601, the second L-shaped rod 1601 is fixedly connected to the upper end of the sliding rod 5, and the lower end of the second L-shaped rod 1601 is slidably connected to a piston plate 1602. When the piston plate 1602 moves to contact with the containing shell 2, the piston plate 1602 continues to move and slides relative to the containing shell 2, and at the same time changes the environment of the space above the containing cavity of the containing shell 2, thereby changing the state of water in the containing cavity of the containing shell 2. An intermediate shell 1603 is fixedly connected to the lower side of the containing shell 2, and a fifth tube 1604 is connected between the containing shell 2 and the intermediate shell 1603. The passage is located above the accommodating cavity of the accommodating shell 2, and the upper side of the middle shell 1603 is connected to an expansion member 1605, which is an elastic air bag, that is, it expands when inflated. A second elastic element 1606 is fixedly connected between the accommodating shell 2 and the four sliding shells 8, and the second elastic element 1606 is a spring, which is used to reset the adjacent sliding shells 8. A third elastic element 1607 is fixedly connected between the second L-shaped rod 1601 and the piston plate 1602, and the third elastic element 1607 is made of elastic rubber, which is used to restore the original relative position relationship between the second L-shaped rod 1601 and the piston plate 1602. The sum of the elastic coefficients of the second elastic elements 1606 in the annular array is less than the elastic coefficient of the third elastic element 1607, which is used to change the relative position of the transported object after the buffer medium fills the accommodating cavity of the base frame 1.

[0030] like Figure 6 and Figure 8-Figure 10 As shown, four cavities 1701 in an annular array are provided on the lower side of the containing shell 2, and the four cavities 1701 are all connected to the fourth channel 1503. A piston rod 1702 fixedly connected to the adjacent sliding shell 8 is slidably connected in the cavity 1701. A fifth channel 18 is provided in the middle and lower part of the containing shell 2, and through holes 19 connected to the adjacent first channels 801 are provided on the back sides of the four sliding shells 8. The four through holes 19 are all connected and coordinated with the fifth channel 18. The connected through holes 19 and the fifth channel 18 are used to reduce the resistance to the mutual circulation of hydraulic oil in different first channels 801, thereby avoiding the situation that the fixing rod 13 is not able to move with the fragile object 101 in time when vibration occurs, resulting in excessive local force on the fragile object 101, thereby causing damage to the fragile object 101.

[0031] In order to strengthen the protection of the fragile items 101 during transportation, the relative sliding between the piston plate 1602 and the containing shell 2 keeps the water in the containing shell 2 relatively still during transportation, thereby providing a stable transportation environment for the fragile items 101 and preventing the water in the containing shell 2 from churning due to vibration during transportation, thereby affecting the normal transportation of the fragile items 101. The specific steps are as follows: when the sliding rod 5 moves downward, the sliding rod 5 drives the second L-shaped rod 1601 to move downward together, and the second L-shaped rod 1601 drives the piston plate 1602 and the third elastic element 1607 to move downward together. When the piston plate 1602 moves downward to the point where it is aligned with the containing shell 2, the piston plate 1602 moves downward to the point where it is aligned with the containing shell 2. After contact, the two are in a relatively sealed state. As the piston plate 1602 continues to move downward, the piston plate 1602 compresses the air above the accommodating chamber of the accommodating shell 2, and the air is discharged from the accommodating shell 2 through the fifth tube 1604. When the piston plate 1602 moves downward to the connection point between the fifth tube 1604 and the accommodating shell 2 and contacts the insulating member 1506, the insulating member 1506 has completely wrapped the fragile item 101. At this time, the water in the accommodating chamber of the accommodating shell 2 is in a stable state (similar to the state of a sealed box filled with water), thereby providing a stable environment for the fragile item 101 during transportation and avoiding churning of the water due to vibration, thereby affecting the transportation of the fragile item 101.

[0032] In order to improve the application scope of the present invention and strengthen the protection of the fragile product 101 during transportation, the relative sliding between the sliding shell 8 and the containing shell 2 and the support of the expansion member 1605 are used to make the fragile product 101 located in the middle of the containing chamber on the containing shell 2 to prevent the bottom of the fragile product 101 from being locally overstressed and broken when vibration occurs during transportation. The specific steps are as follows: when the piston plate 1602 contacts the containing shell 2 and moves downward, the air in the fifth tube 1604 enters the middle shell 1603, and then the air enters the expansion member 1605. At this time, the expansion member 1605 begins to expand. When the piston plate 1602 moves downward to contact the isolation member 1506, the sliding rod 5 continues to move downward, and the second L-shaped rod 1604 is moved downward. 1601 begins to squeeze the third elastic element 1607, and at the same time, the water in the fourth channel 1503 begins to enter the adjacent cavity 1701, and then the water entering the cavity 1701 begins to squeeze the adjacent piston rod 1702 upward, and the piston rod 1702 begins to drive the adjacent sliding shell 8 to move upward, and the sliding shell 8 begins to move upward and squeeze the adjacent second elastic element 1606, and the sliding shell 8 drives the adjacent sliding plate 10 and the parts thereon to move upward together, that is, several fixed rods 13 carry the fragile product 101 to move upward together, and during the process, the expansion member 1605 always supports the bottom of the fragile product 101, so that when vibration occurs during transportation, the fragile product 101 can be fully buffered by water, thereby strengthening the protection of the fragile product 101.

[0033] In order to further strengthen the protection of the fragile product 101 during transportation, the four through holes 19 are connected to the fifth channel 18 to reduce the resistance of the hydraulic oil in the different first channels 801 to flow between each other, so as to prevent the fixing rod 13 from not moving with the fragile product 101 in time when vibration occurs, causing excessive local force on the fragile product 101, resulting in damage to the fragile product 101. The specific steps are as follows: during the upward movement of the sliding shell 8, when the sliding shell 8 moves upward to the point where the four through holes 19 are connected to the fifth channel 18, the staff closes the electric push rod 4, and then when vibration occurs during transportation When the fragile object 101 is transported to the storage tank 2, the fragile object 101 will be displaced under the action of inertia. At this time, the fragile object 101 squeezes the adjacent fixing rod 13, and the squeezed fixing rod 13 moves accordingly. At the same time, the hydraulic oil in different first channels 801 circulates with each other through the four through holes 19 and the fifth channel 18. In this process, several fixing rods 13 are only used as tools to limit the fragile object 101 to the middle of the water in the accommodating chamber of the accommodating shell 2 until the transportation is completed. During the upward movement of the sliding rod 5, that is, the resetting process, the sliding rod 5 drives the second L-shaped rod 1601 and the parts thereon to move upward together until all the parts are reset.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
