Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly provides a movable tray and a packing box for a packing box. Background Art

[0002] A mass spectrometer (abbreviated as MS) is a precision analytical instrument. It uses electromagnetic principles to determine the mass-to-charge ratio (m / z) by ionizing molecules in a sample and detecting the generated ions, and then analyzes the composition and structure of the sample. Mass spectrometers have a wide range of applications in many fields such as medical diagnosis, scientific research, drug development, and food safety.

[0003] In view of the fact that the mass spectrometer may affect the accuracy of its analysis results once it is impacted during handling, therefore, ensuring its safety and stability during transportation is particularly important. The existing packing boxes for transporting mass spectrometers have the following problems: ① The current packing box has a problem of insufficient structural strength, resulting in difficulty in effectively protecting the instrument during transportation and an increased risk of damage. ② There is a lack of a necessary intermediate movable tray assembly inside the packing box. Given the large weight of the instrument itself, this defect limits the possibility of using a forklift for efficient handling at the customer site and instead relies on manual handling, which is not only inefficient but also significantly increases the safety risk of the operators. ③ The existing packaging did not fully consider the balanced distribution of weight during design, and there is a situation where the weights at both ends are inconsistent. If the forklift misinserts the non-designed bearing surface, it will directly cause the center of gravity to shift and lead to a tipping accident, posing a major safety hazard. ④ Given the large weight of the instrument itself, the current packaging solution does not provide a convenient moving solution, affecting the overall operability and use efficiency of the equipment.

[0004] Therefore, there is an urgent need in the art for a new packing box to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to solve one of the above technical problems, that is, to solve at least one of the problems such as insufficient strength of the existing packing box, inconvenient handling, and risk of tipping.

[0006] In a first aspect, the utility model provides a movable tray for a packing box. The movable tray includes: a tray body, a reinforcing member, and a caster assembly. A first limiting assembly is provided on the tray body, and the first limiting assembly is disposed at least at four corners of the tray body and protrudes from the upper surface of the tray body; the reinforcing member is connected to the lower part of the tray body; the caster assembly is connected to the reinforcing member.

[0007] It can be understood that during packaging and transportation, the mass spectrometer is first installed on a movable tray, and then the entire movable tray and the mass spectrometer carried thereon are moved into the packing box. Among them, the first limiting components disposed at least at the four corners of the tray body can form fixed limits on the mass spectrometer carried by the movable tray from multiple directions, ensuring the stability of the mass spectrometer on the movable tray.

[0008] The movable tray for a packing box provided by the present utility model can fix the mass spectrometer on the tray body through the first limiting components when the mass spectrometer needs to be transported, ensuring the stability of the mass spectrometer during transportation. At the same time, the reinforcing members under the tray body enhance the load-bearing capacity and structural rigidity of the entire movable tray, providing a more stable and reliable support platform for the mass spectrometer, which is beneficial to avoiding damage to the mass spectrometer during transportation. Moreover, when the mass spectrometer is transported to the site along with the packing box, the staff can also use the caster assembly to move the entire movable tray and the mass spectrometer carried thereon until the mass spectrometer is moved to the required position. This can effectively reduce the difficulty of manually carrying the instrument, which is not only beneficial to reducing the tipping risk of the mass spectrometer during handling, but also can effectively reduce the safety hazards faced by the staff during handling.

[0009] In some feasible embodiments of the above-mentioned movable tray for a packing box, the first limiting components include a plurality of limiting members, and at least a part of the plurality of limiting members is detachably connected to the tray body.

[0010] With the detachable limiting members, it is not only beneficial to simplify the difficulty of installing and disassembling the mass spectrometer on the movable tray. The staff can easily complete the installation and disassembly of the limiting members without using complex tools, thereby improving work efficiency. Moreover, the detachable limiting members allow the staff to adjust according to the actual size, shape and weight of the mass spectrometer to ensure the best fixing effect.

[0011] In some feasible embodiments of the above-mentioned movable tray for a packing box, at least a part of the plurality of limiting members is connected to the side wall of the tray body and a part of it protrudes from the upper surface of the tray body.

[0012] The limiting members protruding from the upper surface of the tray body can directly contact the side surface of the mass spectrometer. Combining the situation that the limiting members are distributed at the four corners of the tray body, the mass spectrometer can be fixed and limited from multiple directions, which helps to reduce the shaking and displacement of the mass spectrometer during transportation, thereby enhancing the stability of the mass spectrometer.

[0013] In a second aspect, the present utility model also provides a packing box, which includes a base, and a second limiting component is provided on the base, and the second limiting component is used to install the movable tray in any of the above technical solutions.

[0014] During packing, first fix the mass spectrometer on the movable tray through the first limiting component, then move the movable tray and the mass spectrometer together to the base, and at the same time form a fixation on the movable tray through the second limiting component, so as to fix the movable tray and the mass spectrometer on the base for packing and transporting the mass spectrometer. When the vehicle transports the mass spectrometer to the site, after the movable tray and the mass spectrometer are removed from the base, the staff can move the movable tray and the mass spectrometer it carries through the caster assembly until the mass spectrometer is transported to the required position. In this way, not only can the difficulty of manually carrying the mass spectrometer by workers be reduced, effectively reducing the safety hazards faced by the staff during the handling process, but also while ensuring that the mass spectrometer is properly protected, the convenience of handling is effectively improved, achieving a double optimization of protection and efficiency.

[0015] In some feasible embodiments of the above-mentioned packing box, the second limiting component includes a first limiting member and a second limiting member. The first limiting member is formed with a first limiting portion, and the second limiting member is formed with a second limiting portion. The first limiting portion and the second limiting portion cooperate to form a limiting space capable of limiting the tray body.

[0016] Through the limiting space formed by the first limiting portion and the second limiting portion, the tray body can be positioned and fixed, providing a stable support for the movable tray and the mass spectrometer it carries. Combined with the limiting and fixing of the mass spectrometer by the first limiting component, the stability of the mass spectrometer during transportation is further enhanced, effectively preventing the mass spectrometer from shaking or displacing during transportation.

[0017] In some feasible embodiments of the above-mentioned packing box, the first limiting member further includes a first supporting portion, and the second limiting member further includes a second supporting portion. The first limiting portion is formed on the first supporting portion and the first supporting portion is a continuous structure. The second limiting portion is formed on the second supporting portion and the second supporting portion is a discontinuous structure. The second supporting portion is located on both sides of the first supporting portion and is spaced from the first supporting portion.

[0018] By adopting a continuous structure as the first supporting portion, the supporting area of the base for the movable tray can be increased, thereby directly improving the load-bearing capacity of the base and the movable tray, enabling the base and the movable tray to carry a heavier mass spectrometer. On this basis, together with the second supporting portions arranged on both sides of the first supporting portion, the second limiting component is like a force-receiving platform, which can effectively disperse the weight of the movable tray and the mass spectrometer it carries, reducing the risk of single-point stress on the base, and thus enhancing the stability and safety of the overall structure.

[0019] In addition, by arranging the second supporting part at an interval from the first supporting part, a passage for a forklift to insert can be left between the first supporting part and the second supporting part, retaining the convenience of directly using a forklift to carry the movable tray and the mass spectrometer carried thereon.

[0020] In some feasible embodiments of the above-mentioned packaging box, the base further includes a first integral plate, the second limiting component is fixedly arranged on the first integral plate, and a partition fixing part is also arranged on the first integral plate.

[0021] In some feasible embodiments of the above-mentioned packaging box, the base further includes a plurality of reinforcing beams, and the reinforcing beams are arranged at intervals below the first integral plate.

[0022] Through the intervals between the arranged reinforcing beams, sockets can be formed, reserving a passage for the forklift to enter and exit the entire packaging box, enabling the forklift to easily insert from the bottom of the base and lift the entire packaging box and the mass spectrometer it protects, which is beneficial to improving the loading and unloading efficiency. At the same time, the arrangement of the plurality of reinforcing beams at intervals helps to evenly disperse the weight borne by the base, improving the overall load-bearing capacity of the base. Moreover, the addition of the reinforcing beams enhances the rigidity of the base, making it more resistant to deformation and damage during handling and ensuring the stability of the structure.

[0023] In some feasible embodiments of the above-mentioned packaging box, the base further includes a stopper, and the stopper is connected to the first ends of the plurality of reinforcing beams and is used to block the gap between adjacent reinforcing beams near their first ends.

[0024] By providing a stopper at one end of the reinforcing beam, it is ensured that the forklift can only fork the packaging box and the mass spectrometer carried thereon along a preset, safe and reliable path. This design is beneficial to simplifying the operation process of the forklift driver, reducing the possibility of human errors, and avoiding potential dangers such as center-of-gravity imbalance and instrument tipping caused by inserting in the wrong position, which is beneficial to enhancing the stability and safety of the mass spectrometer during handling.

[0025] In some feasible embodiments of the above-mentioned packaging box, the packaging box further includes a partition, and the partition is fixedly connected to the base through the partition fixing part to divide the space inside the packaging box into a first accommodation cavity and a second accommodation cavity.

Detailed implementation manners

[0039] In order to better illustrate the present utility model, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present utility model can still be implemented without some specific details.

[0040] In the description of the present utility model, the terms "upper", "lower", "inner", "outer" and other terms indicating directions or positional relationships are based on the directions or positional relationships during actual use. This is only for the convenience of description and does not indicate or imply that the device to be protected must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, ordinal numbers such as "first", "second" are only for convenience of description and do not indicate or imply relative importance.

[0041] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0042] The following refers to the attached Figures 1 to 10 to describe the movable tray and the packing box provided by the present utility model.

[0043] Please refer to Figures 1 - 2 , the present utility model provides a movable tray for a packing box. The movable tray 1 includes a tray body 13, a reinforcing member 14 and a caster assembly 12. A first limiting assembly 11 is arranged on the tray body 13. The first limiting assembly 11 is arranged at least at the four corners of the tray body 13 and protrudes from the upper surface of the tray body 13; the reinforcing member 14 is connected to the lower part of the tray body 13; the caster assembly 12 is connected to the reinforcing member 14.

[0044] It can be understood that during packaging and transportation, the mass spectrometer 4 is first installed on the movable tray 1, and then the entire movable tray 1 and the mass spectrometer 4 carried thereon are moved into the packing box. Among them, the first limiting assembly 11 arranged at least at the four corners of the tray body 13 can form a fixed limit on the mass spectrometer 4 carried on the movable tray 1 from multiple directions, ensuring the stability of the mass spectrometer 4 on the movable tray 1.

[0045] When the mass spectrometer 4 needs to be transported, the mass spectrometer 4 can be fixed on the tray body 13 through the first limiting component 11 to ensure the stability of the mass spectrometer 4 during transportation. At the same time, the reinforcing member 14 under the tray body 13 enhances the load-bearing capacity and structural rigidity of the entire movable tray 1, providing a more stable and reliable support platform for the mass spectrometer 4, which is beneficial to avoiding damage to the mass spectrometer 4 during transportation. Moreover, when the mass spectrometer 4 is transported to the site with the packing box, the staff can also use the caster assembly 12 to move the entire movable tray 1 and the mass spectrometer 4 it carries until the mass spectrometer 4 is moved to the required position. This can effectively reduce the difficulty of manually carrying the instrument, which is not only beneficial to reducing the tipping risk of the mass spectrometer 4 during handling, but also can effectively reduce the safety hazards faced by the staff during handling.

[0046] In addition, the present utility model also finds that in instruments performing high-precision measurement tasks, pulleys are likely to introduce transmission errors, which will directly affect the accuracy of measurement data. Therefore, most precision instruments do not incorporate pulley structures at the initial design stage. However, in the present utility model, by indirectly introducing the movable tray 1 and the caster assembly 12 located at the bottom of the tray body 13, when reaching the required position, the first limiting component 11 can also be loosened to disassemble the entire mass spectrometer 4 from the movable tray 1. This can avoid the influence of the pulley structure on the measurement data of the mass spectrometer 4 and is beneficial to ensuring the accuracy of the measurement data of the mass spectrometer 4.

[0047] Please refer to Figures 1 - 2 , the caster assembly 12 includes a plurality of casters, and the number of casters is designed according to actual needs. It can be understood that setting casters at the bottom of the tray body 13 enables the movable tray 1 and the mass spectrometer 4 it carries to move easily on the ground without relying on additional handling tools, which is beneficial to reducing the difficulty of manual handling. When the caster assembly 12 includes four casters, as Figure 1 shown, the four casters can be composed of two casters with brakes 121 and two casters without brakes 122. The casters are rubber wheels with a very strong load-bearing capacity. The casters with brakes 121 have universal steering and braking functions, enabling the mass spectrometer 4 installed on the movable tray 1 to move freely with the movable tray 1 and can also be locked when it needs to be stationary. Of course, all four casters can also be casters with brakes 121, which can also meet the requirements of the free movement and stationary state of the movable tray 1 and the mass spectrometer 4 it carries.

[0048] In an application scenario, such as Figure 1 and Figure 2As shown, the movable tray 1 includes a tray body 13 and a reinforcing member 14 disposed inside the tray body 13. The top surface of the tray body 13 is a plane for placing the mass spectrometer 4. The first limiting component 11 is disposed on the top surface of the tray body 13. The cross-section of the reinforcing member 14 is U-shaped, which can improve the overall strength of the movable tray 1. The number of the reinforcing members 14 can be designed according to actual needs. For example, the number of the reinforcing members 14 is three, and the three reinforcing members 14 are fixedly arranged side by side inside the tray. Fixing blocks 141 are provided on the reinforcing members 14 on both sides. Threaded holes are provided in the fixing blocks 141, and the casters can be threadedly connected to the threaded holes in the fixing blocks 141 through bolts.

[0049] Please refer to Figure 1 , the first limiting component 11 includes a plurality of limiting members, and at least a part of the plurality of limiting members is detachably connected to the tray body 13. Through the detachable limiting members, it is not only beneficial to simplify the difficulty of installing and disassembling the mass spectrometer 4 on the movable tray 1. The staff can easily complete the installation and disassembly of the limiting members without using complex tools, thereby improving work efficiency. Moreover, the detachable limiting members also allow the staff to adjust according to the actual size, shape and weight of the mass spectrometer 4 to ensure the best fixing effect.

[0050] Please refer to Figure 2 , at least a part of the plurality of limiting members is connected to the side wall of the tray body 13 and a part of it protrudes from the upper surface of the tray body 13. The limiting members protruding from the upper surface of the tray body 13 can directly contact the side surface of the mass spectrometer 4. Combined with the situation that the limiting members are distributed at the four corners of the tray body 13, the mass spectrometer 4 can be fixed and limited from multiple directions, which helps to reduce the shaking and displacement of the mass spectrometer 4 during transportation, thereby enhancing the stability of the mass spectrometer 4.

[0051] Please refer to Figure 3 , the present utility model further provides a packing box, which includes a base 2. A second limiting component 21 is provided on the base 2, and the second limiting component 21 is used to install the movable tray 1 in any of the foregoing technical solutions.

[0052] It should be noted that the packing box further includes a box body 3 as its main part. The base 2 is connected to the box body 3 to form a cavity. When packing and transporting, the movable tray 1 and the mass spectrometer 4 carried thereon are installed in the cavity.

[0053] During packing, first, the mass spectrometer 4 is fixedly installed on the movable tray 1 through the first limiting component 11. Then, the movable tray 1 and the mass spectrometer 4 are moved together onto the base 2. At the same time, the movable tray 1 is fixed by the second limiting component 21, so as to fix the movable tray 1 and the mass spectrometer 4 on the base 2 for packing and transporting the mass spectrometer 4. When the vehicle transports the mass spectrometer 4 to the site, after the movable tray 1 and the mass spectrometer 4 are removed from the base 2, the staff can move the movable tray 1 and the mass spectrometer 4 it carries through the caster assembly 12 until the mass spectrometer 4 is transported to the required position. In this way, not only can the difficulty of manually carrying the mass spectrometer 4 by workers be reduced, effectively reducing the safety hazards faced by the staff during the handling process, but also while ensuring the proper protection of the mass spectrometer 4, the handling convenience can be effectively improved, achieving a double optimization of protection and efficiency.

[0054] Please refer to Figure 4 , in the case of setting multiple casters, when the movable tray 1 is installed on the base 2 through the second limiting component 21, each caster is in contact with and abuts against the top surface of the base 2. That is, in addition to the second limiting component 21 on the base 2 providing a supporting effect on the tray body 13, each caster also jointly provides an additional support point for the movable tray 1. The dual support mechanism greatly enhances the stability of the movable tray 1 and the mass spectrometer 4 it carries during the handling process. Moreover, in an uneven or vibrating environment, the caster assembly 12 can absorb part of the vibration energy, reducing the vibration amplitude of the tray body 13 and the mass spectrometer 4, which is beneficial to protecting the mass spectrometer 4 from damage, thereby improving the safety of the overall structure.

[0055] Please refer to Figure 5 and Figure 6 , the second limiting component 21 includes a first limiting member 211 and a second limiting member 212. The first limiting member 211 is formed with a first limiting portion 2112, and the second limiting member 212 is formed with a second limiting portion 2122. The first limiting portion 2112 and the second limiting portion 2122 cooperate to form a limiting space capable of limiting the tray body 13. Through the limiting space formed by the first limiting portion 2112 and the second limiting portion 2122, the tray body 13 can be positioned and fixed, and a stable support can be provided for the movable tray 1 and the mass spectrometer 4 it carries. Combined with the limiting and fixing of the mass spectrometer 4 by the first limiting component 11, the stability of the mass spectrometer 4 during transportation is further enhanced, and the mass spectrometer 4 can be effectively prevented from shaking or displacing during transportation.

[0056] More specifically, the first limiting part 2112 limits the movable tray 1 along the first direction, and the second limiting part 2122 limits the movable tray 1 along the second direction, where the first direction is perpendicular to the second direction, and both the first direction and the second direction are any directions on the horizontal plane. For example, as Figure 5 shown, the first direction can be the front-back direction of the base 2 (i.e., the Y direction in Figure 5 ), and the second direction is the left-right direction of the base 2 (i.e., the X direction in Figure 5 ); of course, according to the swing angle of the base 2, the first direction can also be the left-right direction of the base 2, and the second direction is the front-back direction of the base 2.

[0057] In this way, through the synergistic effect of the first limiting part 2112 and the second limiting part 2122, multi-directional limiting of the movable tray 1 on the horizontal plane is achieved, that is, the degrees of freedom of movement of the movable tray 1 in the front-back direction and the left-right direction are simultaneously restricted. Through this dual limiting mechanism, it is ensured that the movable tray 1 is stably fixed on the base 2, so that the movable tray 1 and the mass spectrometer 4 carried by it can also remain stable during vehicle transportation and will not undergo any displacement changes in any direction. Such a design greatly enhances the safety and protection effect of the mass spectrometer 4 during transportation.

[0058] Please continue to refer to Figure 5 and Figure 6 , the first limiting member 211 further includes a first supporting part 2111, the second limiting member 212 further includes a second supporting part 2121. The first limiting part 2112 is formed on the first supporting part 2111 and the first supporting part 2111 is a continuous structure. The second limiting part 2122 is formed on the second supporting part 2121 and the second supporting part 2121 is a discontinuous structure. The second supporting part 2121 is located on both sides of the first supporting part 2111 and is spaced apart from the first supporting part 2111.

[0059] It should be noted that the first supporting part 2111 is a continuous structure, that is, the top surface of the first supporting part 2111 extends continuously along the first direction. Two convex first limiting parts 2112 are formed on the first supporting part 2111. The two first limiting parts 2112 are oppositely arranged along the first direction on the top surface of the first supporting part 2111, making the entire first limiting member 211 in a U-shaped structure; the second supporting part 2121 is a discontinuous structure, that is, the second supporting part 2121 can be divided into two independent support blocks. The two support blocks are separated from each other by the first supporting part 2111. Each of the two support blocks forms a convex second limiting part 2122, and the two second limiting parts 2122 are oppositely arranged along the second direction, making the support blocks and the second limiting parts 2122 thereon together in an L-shaped structure.

[0060] By adopting a continuous structure as the first supporting part 2111, the utility model can increase the supporting area of the base 2 for the movable tray 1, thereby directly improving the load-bearing capacity of the base 2 and the movable tray 1, enabling the base 2 and the movable tray 1 to carry a heavier mass spectrometer 4. On this basis, together with the second supporting parts 2121 arranged on both sides of the first supporting part 2111, the top surface of the second supporting part 2121 is flush with the top surface of the first supporting part 2111, making the second limiting component 21 function as a force-receiving platform, which can effectively disperse the weight of the movable tray 1 and the mass spectrometer 4 it carries, reducing the risk of single-point stress on the base 2 and enhancing the stability and safety of the overall structure.

[0061] It should be noted that the designs of the first limiting part 2112 and the second limiting part 2122 also take flexibility into account. They do not impose any restrictions on the up-and-down direction of the tray body 13, which allows the movable tray 1 and the mass spectrometer 4 it carries to move up and down as needed. In this case, by arranging the second supporting part 2121 at intervals with the first supporting part 2111, a channel can be left between the first supporting part 2111 and the second supporting part 2121 for a forklift, a manual forklift (such as a pallet jack), or other forklift-like handling tools (collectively referred to as forklifts for convenience of description) to insert. This retains the convenience of directly handling the movable tray 1 and the mass spectrometer 4 it carries using a forklift.

[0062] Specifically, based on the arrangement of the second supporting part 2121 at intervals with the first supporting part 2111, please refer to Figure 7 and Figure 8 . A set of casters are respectively arranged on both sides of the first limiting member 211; a first forklift insertion port (for the forks of a forklift-like handling tool to insert) extending along the first direction is formed between the same set of casters and the first limiting member 211, that is, the forklift can insert and pick up the movable tray 1 and the mass spectrometer 4 it carries along the first insertion direction 123 in Figure 7 or Figure 8 .

[0063] As shown in Figure 6 , the base 2 further includes a first integral board 25 and a first strengthening frame 23. The second limiting component 21 is fixedly arranged on the first integral board 25. The first integral board 25 is a three-ply board, and the number of the first integral boards 25 can be one or more, specifically designed according to actual needs. As shown in Figure 6 , the number of the first integral boards 25 is two, and the two first integral boards 25 are fixedly connected in a stacked manner. A partition fixing member 24 is arranged on the topmost first integral board 25. The first strengthening frame 23 is arranged at the bottom of the first integral board 25 as a support strengthening component for the entire three-ply board, which is beneficial to improving the support strength of the base 2.

[0064] On the basis described above, the base 2 further includes a plurality of reinforcing beams 22. The reinforcing beams 22 are arranged at intervals below the first integral plate 25. When a first reinforcing frame 23 is provided at the bottom of the first integral plate 25, the plurality of reinforcing beams 22 are arranged in parallel below the first reinforcing frame 23. Through the intervals between the spaced reinforcing beams 22, sockets can be formed to reserve a passage for the forklift to enter and exit the entire packaging box, enabling the forklift to easily insert from the bottom of the base 2 and lift the entire packaging box and the mass spectrometer 4 it protects, which is beneficial to improving the loading and unloading efficiency. At the same time, the spaced arrangement of the plurality of reinforcing beams 22 helps to evenly disperse the weight borne by the base 2, improving the overall load-bearing capacity of the base 2. Moreover, the addition of the reinforcing beams 22 enhances the rigidity of the base 2, making it more resistant to deformation and damage during handling and ensuring the structural stability.

[0065] Specifically, please refer to Figure 8 , the second forklift socket formed by the interval between two adjacent reinforcing beams 22, that is, the forklift can insert and pick up the base 2 along Figure 8 the second insertion direction 221 in, which can reserve a passage for the forklift to enter and exit the entire packaging box, enabling the forklift to easily insert from the bottom of the base 2 and lift the entire base 2 (i.e., the entire packaging box) and the mass spectrometer 4 it carries, which is beneficial to improving the loading and unloading efficiency. In addition, for the convenience of forklift handling, the first insertion direction 123 can be parallel to the second insertion direction 221.

[0066] On the basis of setting the reinforcing beams 22, the base 2 further includes a stopper 222. The stopper 222 is connected to the first ends of the plurality of reinforcing beams 22 and is used to block the gap between the adjacent reinforcing beams 22 near their first ends. Among them, when the movable tray 1 and the mass spectrometer 4 it carries are installed on the base 2, they are closer to the second ends of the reinforcing beams 22. By providing a stopper 222 at the first ends of the reinforcing beams 22, it is ensured that the forklift can only fork and pick up the packaging box and the mass spectrometer 4 it carries along a preset, safe and reliable path. This design is beneficial to simplifying the operation process of the forklift driver, reducing the possibility of human error, and avoiding potential dangers such as center of gravity imbalance and instrument overturning caused by inserting in the wrong position, which is beneficial to enhancing the stability and safety of the mass spectrometer 4 during handling.

[0067] It should be noted that, please refer to Figure 6 , the stopper 222 can be a continuous entire long strip baffle; the stopper 222 can also be a plurality of discontinuous components, or other structural forms of the stopper 222, as long as it can block the gap at the end of the first end of the reinforcing beam 22 to prevent the forklift from inserting.

[0068] It can be understood that since space needs to be reserved for placing other accessories during boxing, the movable tray 1 and the mass spectrometer 4 carried thereon are often placed close to one side of the base 2, which results in inconsistent weights on both sides of the packing box. In this case, by arranging the blocking member 222 on the side away from the movable tray 1 and the mass spectrometer 4, the forklift can only be inserted from the side close to the movable tray 1 and the mass spectrometer 4, which can make the center of gravity of the entire packing box closer to the forklift, facilitating enhancing the stability and safety of the mass spectrometer 4 during handling and avoiding the situation where the mass spectrometer 4 topples due to unbalanced center of gravity.

[0069] On the basis that the partition fixing member 24 is further provided on the first full board 25, please refer to Figure 9 and Figure 10 , the packing box further includes a partition 36, and the partition 36 is fixedly connected to the base 2 through the partition fixing member 24 to divide the space inside the packing box into a first accommodation cavity and a second accommodation cavity, where the first accommodation cavity is used for installing the movable tray 1 and the mass spectrometer 4 carried thereon, and the second accommodation cavity is used for placing other accessories of the mass spectrometer 4.

[0070] As a specific implementation manner of this embodiment, the box body 3 as the main part of the packing box includes a front board 31, a rear board 32, a left board 33, a right board 34 and a top board 35. The front board 31 and the rear board 32 are arranged on both sides of the base 2 in the front-rear direction, the left board 33 and the right board 34 are arranged on both sides of the base 2 in the left-right direction, and the top board 35 located directly above the base 2 seals the tops of the front board 31, the rear board 32, the left board 33 and the right board 34 to make the entire packing box airtight. The partition 36 is fixed between the base 2 and the top board 35, and the partition 36 divides the internal space of the box body 3 into a first accommodation cavity for placing the mass spectrometer 4 and a second accommodation cavity for placing other accessories of the mass spectrometer 4. Partition fixing members 24 for fixing the partition 36 are provided between the base 2 and the top board 35. As shown in 6, the partition fixing member 24 and the first support part 2111 jointly form a limiting and fixing gap acting on the partition 36, and two parallel partition fixing members 24 can be provided on the top board 35 to form a limiting and fixing gap acting on the partition 36.

[0071] To improve the overall strength and protection ability of the packing box, each plate of the packing box can be composed of plywood and protective parts, such as Figure 10As shown, the top plate 35 includes a second integral plate 351, a second reinforcing frame 352, and an EPE 353. The second integral plate 351 is a plywood board. The second reinforcing frame 352 is disposed on the outer surface of the second integral plate 351, and the EPE 353 is disposed on the inner surface of the second integral plate 351. Such a setting can further enhance the structural strength of the entire packaging box. The presence of the EPE 353 provides an additional layer of cushioning and protection for the mass spectrometer 4, ensuring the safety of the mass spectrometer 4 during transportation.

[0072] The specific working process of this embodiment is as follows: First, the movable tray 1 is clamped to the base 2 of the packaging box. Through the equipment in the production workshop, the mass spectrometer 4 is moved and placed on the movable tray 1, and the mass spectrometer 4 is fixed by the first limiting component 11 to prevent the displacement of the mass spectrometer 4. Then, the front plate 31, the rear plate 32, the left plate 33, the right plate 34, and the partition 36 are fixed to the base 2 by self-tapping screws or partition fixing parts 24. The relevant accessories are placed in the relevant accessory placement space. Finally, the top plate 35 is fixed, and thus the packaging of the mass spectrometer 4 is completed. Due to the presence of the stopper 222, the forklift can only fork from one side, which helps prevent the situation where the mass spectrometer 4 topples over due to the unstable center of gravity of the packaging box. Then, the packaging box together with the mass spectrometer 4 is forked onto the logistics vehicle by the forklift for transportation.

[0073] After arriving at the customer's site, the forklift places the transfer packaging box on the ground through the second forklift socket. Remove the plates of the packaging box except the base 2. The staff can fork down the movable tray 1 together with the mass spectrometer 4 along the first forklift socket and place them on the ground through the forklift. And the mass spectrometer 4 can move freely along with the movable tray 1 through the setting of the caster assembly 12, so that the mass spectrometer 4 can be moved to the required position.

[0074] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
