Description

Technical Field

[0001] This utility model belongs to the field of container technology, and in particular relates to a new type of prefabricated expandable container. Background Technology

[0002] A container is a large container used for loading and transporting goods. Containers can also be used to move machinery and equipment. Container shipping is an important mode of transportation in international trade.

[0003] Modern shipping containers are enormous, and when not in use, they tend to occupy a large area. Because most containers lack a proper retractable mechanism, their internal space cannot be fully utilized when not loaded or transporting goods, resulting in a significant amount of storage space being taken up and poor usability. Utility Model Content

[0004] The purpose of this utility model is to address the problem that current shipping containers are bulky and occupy a large area when not in use. Because most shipping containers lack a proper retractable mechanism, their internal space cannot be fully utilized when not loaded or transporting goods, resulting in a large space occupied and poor performance. Therefore, a new type of prefabricated expandable shipping container is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel prefabricated expandable container, comprising an outer shell, an inner shell slidably mounted on the inner wall of the outer shell, a top cover fixedly mounted on the top of the outer shell, a telescopic component provided on the inner wall of the top cover, a buckle component provided on the telescopic component, and slots provided on both sides of the top cover.

[0006] The telescopic assembly includes a drive threaded sleeve and a transmission rod. The drive threaded sleeve is rotatably mounted on the inner wall of the top cover side wall with a through hole. The transmission rod is rotatably mounted on the inner wall of the top cover. Second bevel gears are fixedly mounted at both ends of the transmission rod. A first threaded cylinder and a second threaded cylinder are rotatably mounted on the inner wall of the outer shell.

[0007] As a further description of the above technical solution:

[0008] The inner walls of the first and second threaded cylinders are threaded with threaded rods. A limit rod is slidably installed on the inner wall of one end of the threaded rod, and an outer frame is rotatably installed on the other end of the threaded rod.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the outer frame is fixedly connected to the outer wall of the inner shell, one end of the limiting rod is rotatably mounted on the outer wall of the outer frame, and a first bevel gear is fixedly mounted on the outer wall of the first threaded cylinder.

[0011] As a further description of the above technical solution:

[0012] A driven bevel gear is fixedly installed on the outer wall of the second threaded cylinder. The driven bevel gear is meshed with a second bevel gear at one end of the transmission rod, and the second bevel gear at the other end of the transmission rod is meshed with a first bevel gear.

[0013] As a further description of the above technical solution:

[0014] A power rod is fixedly installed at the bottom of the drive threaded sleeve, and a drive bevel gear is fixedly installed at the other end of the power rod. The drive bevel gear and the driven bevel gear are meshed together.

[0015] As a further description of the above technical solution:

[0016] The buckle assembly includes a housing, which is fixedly installed on the outer wall of the outer frame. A telescopic rod is fixedly installed on the inner wall of the housing. Insert blocks are fixedly installed at both ends of the telescopic rod. A spring is fitted on the outer wall of the telescopic rod.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by providing a telescopic component, one end of the output shaft of the driving tool is first threadedly connected to the driving threaded sleeve. When the driving tool is started, the output shaft of the driving tool drives the driving threaded sleeve to rotate, which in turn drives the power rod to rotate. The power rod then drives the driving bevel gear to rotate. The driving bevel gear meshes with the driven bevel gear, causing it to rotate. Simultaneously, the driven bevel gear rotates, causing the second threaded cylinder to rotate. The driven bevel gear also meshes with the second bevel gear at one end of the transmission rod, causing it to rotate. The second bevel gear at the other end of the transmission rod meshes with the first bevel gear, causing the first bevel gear to rotate the first threaded cylinder. The rotation causes the first and second threaded cylinders to rotate synchronously. The inner walls of the first and second threaded cylinders are threadedly connected to the threaded rod. As the first and second threaded cylinders rotate, the threaded rod is displaced on its inner wall. The threaded rod then drives the outer frame, which in turn drives the inner shell to move, causing it to retract into the inner wall of the outer shell. The inner wall of one end of the threaded rod is slidably connected to the limiting rod. When the threaded rod moves to the inner wall of the first and second threaded cylinders, the limiting rod simultaneously retracts into the inner wall of one end of the threaded rod. This design effectively allows the container to be stored, avoiding the need to occupy a large amount of container storage space when not in use, resulting in good performance.

[0019] 2. In this utility model, by setting a buckle assembly, when the inner shell is retracted into the outer shell, the outer frame drives the buckle assembly to move, so that it is in the buckle slots set on both sides of the top cover. The insert is initially squeezed by the inner wall of the buckle slot, so that it is retracted into the shell. The spring set inside the shell is compressed and forms a compressed state. When the insert is fully inserted into the buckle slot, the insert is completely aligned with the inside of the buckle slot. Due to the elastic force generated by the spring in the compressed state, it drives the insert to move out of the shell again. The insert is also aligned with the inside of the buckle slot, so that the buckle assembly is fixed in the buckle slot. Through this design, the container in the retracted state is effectively fixed, avoiding the displacement of the screw due to external vibration, preventing the inner shell from moving out of the outer shell, greatly improving the stability of the container, and the use effect is good.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a novel prefabricated expandable container, including an outer shell 1, an inner shell 2 slidably installed on the inner wall of the outer shell 1, a top cover 3 fixedly installed on the top of the outer shell 1, a telescopic component 4 provided on the inner wall of the top cover 3, a buckle component 5 provided on the telescopic component 4, and slots provided on both sides of the top cover 3.

[0028] The telescopic component 4 includes a drive threaded sleeve 41 and a transmission rod 47. The drive threaded sleeve 41 is rotatably mounted on the inner wall of the top cover 3 with a through hole. The transmission rod 47 is rotatably mounted on the inner wall of the top cover 3. A second bevel gear 49 is fixedly mounted at both ends of the transmission rod 47. A first threaded cylinder 42 and a second threaded cylinder 43 are rotatably mounted on the inner wall of the outer shell 1.

[0029] A threaded rod 44 is threadedly installed on the inner wall of the first threaded cylinder 42 and the second threaded cylinder 43. A limit rod 45 is slidably installed on the inner wall of one end of the threaded rod 44. An outer frame 48 is rotatably installed on the other end of the threaded rod 44. The inner wall of the outer frame 48 is fixedly connected to the outer wall of the inner shell 2. One end of the limit rod 45 is rotatably installed on the outer wall of the outer frame 48. A first bevel gear 46 is fixedly installed on the outer wall of the first threaded cylinder 42. A driven bevel gear 410 is fixedly installed on the outer wall of the second threaded cylinder 43. The driven bevel gear 410 is meshed with a second bevel gear 49 provided at one end of the transmission rod 47. The second bevel gear 49 provided at the other end of the transmission rod 47 is meshed with the first bevel gear 46. A power rod 412 is fixedly installed at the bottom of the driving threaded sleeve 41. A driving bevel gear 411 is fixedly installed at the other end of the power rod 412. The driving bevel gear 411 is meshed with the driven bevel gear 410.

[0030] The specific implementation method is as follows: First, connect one end of the output shaft of the driving tool to the driving threaded sleeve 41. Start the driving tool. The output shaft of the driving tool drives the driving threaded sleeve 41 to rotate. The driving threaded sleeve 41 drives the power rod 412 to rotate. The power rod 412 drives the driving bevel gear 411 to rotate. The driving bevel gear 411 meshes with the driven bevel gear 410, causing it to drive the driven bevel gear 410 to rotate. At the same time, the driven bevel gear 410 rotates, causing the second threaded cylinder 43 to rotate. The driven bevel gear 410 also meshes with the second bevel gear 49 at one end of the transmission rod 47, causing it to drive the transmission rod 47 to rotate. The second bevel gear 49 at the other end of the transmission rod 47 meshes with the first bevel gear. The first bevel gear 46 meshes with the second threaded cylinder 43, causing the first threaded cylinder 42 to rotate synchronously with the second threaded cylinder 43. The inner walls of the first threaded cylinder 42 and the second threaded cylinder 43 are threadedly connected to the threaded rod 44. When the first threaded cylinder 42 and the second threaded cylinder 43 rotate, the threaded rod 44 is displaced on its inner wall. The threaded rod 44 then drives the outer frame 48, and the outer frame 48 drives the inner shell 2 to move, causing it to move on the inner wall of the outer shell 1, thus retracting the inner shell 2 into the outer shell 1. The inner wall of one end of the threaded rod 44 is slidably connected to the limiting rod 45. When the threaded rod 44 moves to the inner wall of the first threaded cylinder 42 and the second threaded cylinder 43, the limiting rod 45 simultaneously retracts into the inner wall of one end of the threaded rod 44.

[0031] The buckle assembly 5 includes a housing 51, which is fixedly installed on the outer wall of the outer frame 48. A telescopic rod 52 is fixedly installed on the inner wall of the housing 51. Insert blocks 54 are fixedly installed at both ends of the telescopic rod 52. A spring 53 is fitted on the outer wall of the telescopic rod 52.

[0032] The specific implementation method is as follows: When the inner shell 2 is retracted into the outer shell 1, the outer frame 48 drives the buckle assembly 5 to move, so that it is in the buckle slots set on both sides of the top cover 3. The insert 54 is initially squeezed by the inner wall of the buckle slot, so that it is retracted into the inner shell 51. The spring 53 set inside the shell 51 is squeezed and forms a compressed state. When the insert 54 is fully inserted into the buckle slot, the insert 54 is completely overlapped with the inside of the buckle slot. Because the spring 53 in the compressed state generates elastic force, it drives the insert 54 to move out of the outer shell 51 again. The insert 54 also overlaps with the inside of the buckle slot, so that the buckle assembly 5 is fixed in the buckle slot.

[0033] Working principle: First, connect one end of the output shaft of the drive tool to the drive threaded sleeve 41. Start the drive tool, and the output shaft of the drive tool drives the drive threaded sleeve 41 to rotate. The drive threaded sleeve 41 drives the power rod 412 to rotate, and the power rod 412 drives the drive bevel gear 411 to rotate. The drive bevel gear 411 meshes with the driven bevel gear 410, causing it to rotate. Simultaneously, the driven bevel gear 410 rotates, causing the second threaded cylinder 43 to rotate. The driven bevel gear 410 also meshes with the second bevel gear 49 at one end of the transmission rod 47, causing it to rotate. The second bevel gear 49 at the other end of the transmission rod 47 meshes with the first bevel gear 46, causing the first bevel gear 46 to rotate, making the first threaded cylinder 42 and the second threaded cylinder 43 rotate synchronously. The inner walls of the first threaded cylinder 42 and the second threaded cylinder 43 are threadedly connected to the threaded rod 44. When the first threaded cylinder 42 and the second threaded cylinder 43 rotate... Simultaneously, the threaded rod 44 is displaced on its inner wall, which in turn drives the outer frame 48, which in turn drives the inner shell 2 to move, causing it to move on the inner wall of the outer shell 1, thus retracting the inner shell 2 into the outer shell 1. The inner wall of one end of the threaded rod 44 is slidably connected to the limiting rod 45. When the threaded rod 44 moves to the inner wall of the first threaded cylinder 42 and the second threaded cylinder 43, the limiting rod 45 simultaneously retracts into the inner wall of one end of the threaded rod 44, retracting the inner shell 2 into the outer shell 1. At the same time, the outer frame 48 drives the buckle assembly 5 to move. The insert 54 is initially pressed by the inner wall of the slot on both sides of the top cover 3, causing it to retract into the inside of the housing 51. The spring 53 inside the housing 51 is compressed. When the insert 54 is fully inserted into the slot, it overlaps with the inside of the slot. The spring 53, which is in a compressed state, generates elastic force, causing the insert 54 to move out of the housing 51 again. The insert 54 also overlaps with the inside of the slot, thus fixing the buckle assembly 5 into the slot.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
