Description

Technical Field

[0001] This invention relates to the field of carbon fiber material transportation technology, specifically to a carbon fiber transport box with an adjustable limiting structure inside. Background Technology

[0002] Carbon fiber composites are widely used in aerospace, automotive manufacturing, sporting goods, and wind turbine blades due to their excellent properties such as high strength, low density, and corrosion resistance. The storage and securing conditions for carbon fiber products after processing are crucial. Although carbon fiber has high strength, its surface hardness is relatively low. Improper securing during transportation can easily lead to surface scratches, delamination, or structural damage due to vibration and impact, affecting product performance and quality.

[0003] Currently, carbon fiber products are typically secured and protected during transportation using methods such as foam filling, air cushion film wrapping, or custom foam molds. However, existing transport boxes have the following problems: First, the internal limiting structures are mostly fixed, unable to be adjusted according to the different shapes and sizes of carbon fiber products, resulting in poor versatility. Transporting a variety of small batches of carbon fiber products requires various sizes of boxes, leading to high costs. Second, traditional filling methods are prone to displacement during transportation, causing products to loosen and failing to provide continuous and stable limiting protection. Third, existing boxes lack the function of controlling environmental parameters such as temperature and humidity inside the box. For some temperature and humidity sensitive carbon fiber prepregs or molded products, environmental changes during transportation may affect their performance.

[0004] Therefore, there is an urgent need for a transport box with an adjustable limiting structure inside, capable of adapting to carbon fiber products of different sizes and having environmental control functions. Summary of the Invention

[0015] As a further embodiment of the present invention: a locking groove is provided on the rear side of the bottom wall of the storage compartment, the inner wall of the locking groove is slidably connected to the outer wall of the locking block, and the rear end of the threaded rod extends into the interior of the locking groove, and the rear end of the threaded rod is rotatably connected to the front end of the locking block.

[0016] As a further embodiment of the present invention: the auxiliary positioning mechanism includes an inverted U-shaped frame, a threaded column, a lifting block, and an upper extension column. The upper rear end of the housing is fixedly connected to the front end of the inverted U-shaped frame. A threaded groove is provided through the upper end of the inverted U-shaped frame.

Once the box is installed inside the support frame, the docking plate opens, allowing the box to quickly enter the storage compartment. The support platform facilitates precise positioning of the carbon fiber products, making them more stable during movement. The addition of a handling handle makes retrieving the box easier. The main storage compartment and placement rack ensure stable placement of the box within the support frame, providing better protection for the carbon fiber products inside. Furthermore, a small thermostat installed inside the temperature-controlled vent maintains a constant internal temperature while keeping the box lightweight, providing a stable environment for the carbon fiber products during transportation.

[0022] This invention utilizes magnetic blocks to promptly rotate the docking plate when the box is installed inside the support frame, thereby opening the storage compartment. Furthermore, the magnetic blocks' properties allow the docking plate to rotate in the opposite direction when the box is removed from the support frame, closing the storage compartment. This ensures that the box's installation and the storage compartment's closure are synchronized. Locking blocks control the position of the docking plate, improving its stability during use.

[0023] This invention utilizes a lifting block that works in conjunction with a locking block to improve the securing effect on the docking plate. Furthermore, the threaded post allows the lifting block to move up and down, facilitating the opening of the docking plate. The linkage plate and / or lower plate synchronously drive the transmission frame to rise and fall. When the lifting block moves upward, the locking of the translation block's position is simultaneously released, allowing the translation block to move the support platform out of the storage compartment. This improves the linkage between the lifting block and the translation block, enhancing the ease of retrieving carbon fiber products. Attached Figure Description

[0035] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0036] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1:

[0038] Carbon fiber composites are widely used in aerospace, automotive manufacturing, sporting goods, and wind turbine blades due to their superior properties such as high strength, low density, and corrosion resistance. During transportation, carbon fiber products require restraint and fixation based on their shape and size to prevent surface scratches or structural damage caused by vibration and collisions. However, existing transport boxes typically have fixed internal restraint structures, which cannot be flexibly adjusted to accommodate different carbon fiber product specifications, resulting in poor versatility.

[0039] Therefore, in order to effectively solve the above problems, this application proposes a carbon fiber transport box with an adjustable limiting structure inside, as shown in the attached drawings of the specification. Figure 1-10 As shown, the container includes a main body 1, which includes a container 11, a support frame 12 connected to the outer wall of the container 11, a storage compartment 13 opened inside the container 11, and a docking mechanism 2 connected to the rear side of the container 11. The docking mechanism 2 includes:

[0040] The rear end of the housing 11 has two grooves, the top walls of which are rotatably connected to the upper end of the rotating shaft 22. The rear end of the housing 11 is connected to an auxiliary positioning mechanism 5, and the front end of the housing 11 has a latching groove 7.

[0041] The two docking plates 21 each have through holes on the upper ends of the sides of the two docking plates 21 that are far apart from each other. The inner walls of the two through holes are fixedly connected to the outer wall of the rotating shaft 22.

[0042] The support platform 23 is connected to the inner wall of the storage compartment 13 through the linkage mechanism 6. The top wall of the storage compartment 13 is provided with a constant temperature port 28. A small thermostat is fixedly connected inside the constant temperature port 28, and the bottom wall of the storage compartment 13 is connected with a locking mechanism 4.

[0043] The placement rack 25 and the support rack 12 have a main storage compartment 24 at the front end. The inner front wall of the support rack 12 is fixedly connected to the front end of the placement rack 25, and the upper end of the placement rack 25 is flush with the lower wall of the main storage compartment 24. The placement rack 25 is connected to a feeding mechanism 3.

[0044] The upper end of the housing 11 has a telescopic buckle groove 26, and the telescopic buckle groove 26 is connected to the handle 27.

[0045] Specific workflow: Start the support frame 12, use the linkage mechanism 6 to fix the position of the support platform 23, then place the carbon fiber product on the support platform 23, install the box 11 above the placement rack 25 through the main storage 24, so that half of the box 11 enters the main storage 24, at this time the locking mechanism 4 is released from the restriction on the docking plate 21, and then the box 11 is moved completely into the main storage 24. At this time, the feeding mechanism 3 will push the docking plate 21 to open, so that the support frame 12 and the box 11 are docked.

[0046] When it is necessary to retrieve the box 11, it can be directly taken out from the inside of the main storage compartment 24, and then the box 11 can be moved by holding the handling handle 27. When the box 11 is taken out from the inside of the support frame 12, the small thermostat inside the thermostatic port 28 will be activated simultaneously to keep the temperature inside the box 11 within a suitable range.

[0047] A pivot can be rotatably connected to one side of the inner wall of the telescopic slot 26, and the handling handle 27 can be fixedly connected to the pivot. When not in use, the handling handle 27 can be rotated and stored inside the telescopic slot 26.

[0048] Additionally, a storage hole can be made in the bottom wall of the handling handle 27, and a telescopic rod can be fixedly connected to the bottom wall of the telescopic buckle groove 26, so that the top wall of the telescopic rod is fixedly connected to the lower end of the spring, and the upper end of the spring is fixedly connected to the top wall of the storage hole. A limiting block is set at the top of the telescopic rod to limit the position of the handling handle 27 and prevent the handling handle 27 from detaching.

[0049] Furthermore, with the docking plate 21 and rotating shaft 22 in place, the docking plate 21 opens after the box 11 is installed inside the support frame 12, allowing the box to quickly enter the storage compartment 13. The support platform 23 facilitates the positioning of the carbon fiber products, making them more stable during movement. The handling handle 27 makes it easier to pick up the box 11. The main storage compartment 24 and the placement rack 25 allow the box 11 to be placed more stably inside the support frame 12, thus providing better protection for the carbon fiber products inside the box 11. The small thermostat installed inside the temperature control port 28 keeps the box 11 lightweight while maintaining a constant internal temperature, providing a stable environment for the carbon fiber products during transportation.

[0050] Example 2:

[0051] Based on Embodiment 1, as shown in the accompanying drawings of the specification. Figure 1-10 As shown, the feeding mechanism 3 includes a mounting plate 31, an extension rod 32, and a magnetic block 34. The upper rear side of the placement frame 25 is fixedly connected to the lower end of the mounting plate 31. The front end of the mounting plate 31 is fixedly connected to the rear end of the extension rod 32. The front end of the extension rod 32 is fixedly connected to the rear end of the magnetic block 34. A material passage 33 is provided at the upper end of the placement frame 25 and below the extension rod 32. An iron block is fixedly connected to the rear end of the docking plate 21, and the iron block and the magnetic block 34 cooperate with each other.

[0052] The locking mechanism 4 includes a rotary block 41, a threaded rod 42, and a locking block 44. A threaded hole is provided on the lower front side of the housing 11. The inner wall of the threaded hole is spirally connected to the outer wall of the threaded rod 42. The front end of the threaded rod 42 is fixedly connected to the rear end of the rotary block 41. A locking groove 43 is provided on the rear side of the bottom wall of the storage compartment 13. The inner wall of the locking groove 43 is slidably connected to the outer wall of the locking block 44. The rear end of the threaded rod 42 extends into the interior of the locking groove 43. The rear end of the threaded rod 42 is rotatably connected to the front end of the locking block 44.

[0053] Specific workflow: When the box 11 is installed inside the main storage compartment 24, the rotating block 41 can be rotated first, and the rotating block 41 drives the threaded rod 42 to rotate, thereby moving the threaded rod 42. The movement of the threaded rod 42 pushes the locking block 44 to move along the locking groove 43. At this time, the restriction on the docking plate 21 can be broken, and the position of the docking plate 21 can be restricted by reversing the operation.

[0054] At this point, the box 11 is installed inside the main storage compartment 24. The magnetic block 34 at the front end of the extension rod 32 will push the docking plate 21 to rotate along the rotating shaft 22, thereby opening the storage compartment 13. When the box 11 is taken out, the magnetic block 34 will attract the iron block, thereby pulling the docking plate 21 to rotate in the opposite direction along the rotating shaft 22, which will close the storage compartment 13.

[0055] The extension rod 32 can also be configured as an electric telescopic rod. By utilizing the characteristics of the electric telescopic rod, the position of the magnetic block 34 can be changed, thereby controlling the degree to which the storage compartment 13 is opened.

[0056] Furthermore, by setting the magnetic block 34, when the box 11 is installed inside the support frame 12, it can push the docking plate 21 to rotate in time, thereby opening the storage compartment 13. And by utilizing the characteristics of the magnetic block 34, when the box 11 is taken out from inside the support frame 12, it can pull the docking plate 21 to rotate in the opposite direction, closing the storage compartment 13. This allows the box 11 to be linked with the closing of the storage compartment 13 when it is installed inside the support frame 12. The position of the docking plate 21 can be controlled by the locking block 44, improving the stability of the docking plate 21 during use.

[0057] Example 3:

[0058] Based on Embodiment 2, as shown in the accompanying drawings of the specification. Figure 1-10 As shown, the auxiliary positioning mechanism 5 includes an inverted U-shaped frame 51, a threaded column 52, a lifting block 53, and an upper extension column 54. The upper rear end of the housing 11 is fixedly connected to the front end of the inverted U-shaped frame 51. A threaded groove is provided through the upper end of the inverted U-shaped frame 51. The inner wall of the threaded groove is spirally connected to the outer wall of the threaded column 52. The upper end of the threaded column 52 is fixedly connected to the lower end of the upper extension column 54. The inner side wall of the inverted U-shaped frame 51 is slidably connected to the outer wall of the lifting block 53. The upper end of the lifting block 53 is rotatably connected to the lower end of the threaded column 52. The lifting block 53 and the docking plate 21 cooperate with each other. A sealing door 8 is rotatably connected above the main storage compartment 24.

[0059] The linkage mechanism 6 includes a linkage plate 61, a lower plate 62, a transmission frame 63, and a translation block 65. Translation rails 67 are provided on both the left and right side walls of the storage compartment 13. The inner walls of both translation rails 67 are slidably connected to the outer walls of the translation blocks 65. The opposite sides of the two translation blocks 65 are fixedly connected to the left and right side walls of the support platform 23. Lifting limit grooves 66 are provided above the left and right side walls of the storage compartment 13. The inner walls of both lifting limit grooves 66 are slidably connected to the outer walls of the transmission frame 63. Both are connected to the translation slide rail 67. The lower ends of the two translation blocks 65 extend into the interior of the translation slide rail 67. The upper ends of the two translation blocks 65 are provided with locking grooves 64, and the locking grooves 64 cooperate with the transmission frame 63. The rear ends of the two transmission frames 63 are fixedly connected to the lower connecting plate 62 on the side that is close to each other. The upper ends of the two lower connecting plates 62 are fixedly connected to the lower end of the same linkage plate 61, and the rear end of the linkage plate 61 extends to the outside of the housing 11. The linkage plate 61 is fixedly connected to the upper end of the lifting block 53.

[0060] Specific workflow: When it is necessary to open the storage compartment 13 to retrieve the carbon fiber products inside, rotate the upper extension column 54 and the threaded column 52. Utilize the helical connection between the threaded column 52 and the inverted U-shaped frame 51 to make the threaded column 52 move upward, thereby driving the lifting block 53 to move upward until the lifting block 53 moves to a position where it no longer contacts the docking plate 21. Simultaneously, as the lifting block 53 moves upward, it will synchronously drive the linkage plate 61, the lower connecting plate 62, and the transmission frame 63 to move upward. The transmission frame 63 will then move out of the slot 64, thereby disconnecting the restriction on the position of the translation block 65. At this point, the support platform 23 and the translation block 65 can move along the translation slide rail 67, allowing the support platform 23 to move to the outside of the housing 11.

[0061] Additionally, a rotating rod can be rotatably connected to the lower end of the lifting block 53, and an elliptical block can be fixedly connected to the outer wall of the rotating rod, using the shape characteristics of the elliptical block to raise and lower the lifting block 53.

[0062] An elastic plate can be installed on the upper end of the support platform 23 to protect the carbon fiber products and reduce the impact on the carbon fiber products when shaking.

[0063] Furthermore, the interior of the housing 11 is equipped with a lifting chamber, and the lower connecting plate 62 and the linkage plate 61 extend to the outside of the housing 11 through the lifting chamber, and the outer walls of the linkage plate 61 and the lower connecting plate 62 are slidably connected to the inner wall of the lifting chamber.

[0064] Furthermore, the lifting block 53 can cooperate with the locking block 44 to improve the fixing effect on the docking plate 21, and the threaded post 52 can make the lifting block 53 rise and fall, making it easier to open the docking plate 21. The linkage plate 61 and the lower plate 62 can synchronously drive the transmission frame 63 to rise and fall. When the lifting block 53 moves upward, the locking of the position of the translation block 65 can be released simultaneously, allowing the translation block 65 to move the support platform 23 out of the storage compartment 13. This improves the linkage between the lifting block 53 and the translation block 65, and improves the convenience of taking out carbon fiber products.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
