Quickly expandable special transport container structure

Abstract

This invention discloses a rapidly expandable special transport container structure, belonging to the field of container technology. The invention includes a first container body, a second container body, and multiple positioning pins. An expansion slot is provided on one side of the first container body, and an expansion frame is slidably connected to the inner wall of the expansion slot. One side of the expansion frame is connected to one side of the second container body. A sealing device is provided on the inner wall of the expansion slot, and the sealing device includes a through groove and a connecting frame. In this invention, the sealing strip moves upward, which in turn moves a moving plate to compress a first spring, causing the first spring to generate a rebound force. When the expansion frame is in place, the rebound force of the first spring causes the first spring to drive the moving plate to reset, which in turn causes the moving plate to drive the sealing strip to move in the opposite direction, allowing the sealing strip to engage with another sealing slot. This ensures better sealing when the container is expanded, preventing leakage between the expanded containers and avoiding damage to the goods inside the container due to leakage.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, by setting a sealing device, when the second container moves the extension frame, the sealing strip slides out of one of the sealing grooves and moves upward. Then, the moving plate moves and compresses the first spring, causing the first spring to generate a rebound force. When the extension frame moves into place, the rebound force of the first spring causes the first spring to drive the moving plate to reset, which in turn causes the moving plate to move the sealing strip in the opposite direction, so that the sealing strip is inserted into the other sealing groove. This ensures better sealing when the container is extended, and avoids leakage between the extended first and second containers, which could damage the goods inside the container.

[0026] 2. In this invention, by setting a fixing device, when the fixing boxes at the bottom of the first and second boxes are inserted into the outer wall of the positioning pin, the top of the positioning pin contacts and presses the second pressing block, causing the second pressing block to move upward and press the first pressing block, causing the first pressing block to move inward, thereby driving one end of the connecting rod to move, and causing the connecting rod to rotate through the rotating rod limit, causing the other end of the connecting rod to move in the opposite direction, thereby causing the connecting rod to drive the fixing pin to move outward through the movable block, thus fixing the positioning pin with the fixing pin, making it more convenient during transportation and loading / unloading, avoiding the need for manual fixing, thereby reducing the labor intensity of manual labor and improving work efficiency.

[0027] 3. In this invention, by setting up an extension device, the first bevel gear is driven to rotate by a motor, which in turn drives the rotating rod to rotate through the second bevel gear. The rotating rod drives the threaded rod to rotate through the connecting rod, and the threaded rod drives the threaded seat to move, which in turn drives the second container to move. This makes it more convenient for the second container to be extended, avoiding the need for external equipment to extend it in the traditional way, thereby improving the practicality of the container.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-10This invention provides a technical solution: a rapidly expandable special transport container structure, including a first container 1, a second container 2, and multiple positioning pins 9. An expansion slot 4 is provided on one side of the first container 1, and an expansion frame 3 is slidably connected to the inner wall of the expansion slot 4. One side of the expansion frame 3 is connected to one side of the second container 2. A sealing device 5 is provided on the inner wall of the expansion slot 4, the sealing device 5 including a through slot 509 and a connecting frame 502. A sealing strip 501 is slidably connected to the inner wall of the through slot 509. Multiple movable slots 508 are provided on both sides of the inner wall of the through slot 509. A movable plate 506 is slidably connected to the inner wall of the movable slot 508. A sliding sleeve is embedded in the movable plate 506, and a sliding rod 505 is slidably connected inside the sliding sleeve. A first positioning pin 9 is sleeved on the outer wall of the sliding rod 505. The spring 507 and the sealing strip 501 have multiple first limiting grooves 504 on their tops. A first fixing rod 503 is slidably connected in the first limiting groove 504. The two ends of the first spring 507 are respectively connected to one side of the inner wall of the moving groove 508 and one side of the moving plate 506. The two ends of the sliding rod 505 are respectively connected to both sides of the inner wall of the moving groove 508. The connecting frame 502 is connected to the outer wall of the first housing 1 and is located above the through groove 509. The through groove 509 is opened around the outer wall of the first housing 1, and the end of the first fixing rod 503 away from the sealing strip 501 is connected to the top of the inner wall of the connecting frame 502. The outer wall of the extension frame 3 has two sealing grooves 8, and one side of the sealing strip 501 is in contact with the inner wall of one of the sealing grooves 8.

[0042] The specific implementation method is as follows: By setting a sealing device 5, the second box 2 moves, driving the extension frame 3 to move, so that the sealing strip 501 in the through groove 509 is squeezed through one side of the sealing groove 8, and the sealing strip 501 moves upward, thereby causing the sealing strip 501 to drive the moving plate 506 to move. While the moving plate 506 moves, it squeezes the first spring 507, causing the first spring 507 to generate a rebound force. By setting the moving plate 506 to slide on the outer wall of the slide rod 505, the moving plate 506 moves more stably, avoiding deviation that may affect operation. Then, when the extension frame 3 moves into place, the rebound force of the first spring 507 causes the first spring 507 to drive the moving plate 506 to reset in the opposite direction, thereby causing the moving plate 506 to drive the sealing strip 501 to move in the opposite direction, so that the sealing strip 501 is inserted and sealed with another sealing groove 8, thereby ensuring better sealing when the container is extended, preventing damage to the internal goods due to leakage, and improving the practicality of the device.

[0043] Two fixing devices 6 are connected to the bottom of both the first box 1 and the bottom of the second box 2. Each fixing device 6 includes a fixing box 601. Both sides of the inner wall of the fixing box 601 have extrusion grooves 614. A connecting groove 603 is formed on one side of each extrusion groove 614, and a fixing groove 604 is formed on one side of each connecting groove 603. One side of the fixing groove 604 communicates with the inner wall of the fixing box 601. First extrusion blocks 605 are slidably connected to the inner walls of both extrusion grooves 614. The sides of the two first extrusion blocks 605 that are furthest apart have internal grooves, and the inner walls of the internal grooves are hinged. A connecting rod 607 is connected to a second spring 606 on one side of the connecting rod 607. The other end of the second spring 606 is connected to one side of the inner wall of the connecting groove 603. A fixing pin 612 is slidably connected to the inner wall of the fixing groove 604. A movable block 611 is connected to one side of the fixing pin 612. A movable groove 610 is opened on one side of the movable block 611. The same stroke rod 609 is connected between the inner walls of the movable grooves 610. A stroke groove 608 is opened on one side of the connecting rod 607. The inner wall of the stroke groove 608 is slidably connected to the outer wall of the stroke rod 609. The connecting rod 607 is divided into two parts on both sides. The connecting rod 607 is slidably connected to both sides of the inner wall of the movable groove 610. A rotating groove is provided inside the connecting rod 607, and a rotating rod 620 is rotatably connected to the inner wall of the rotating groove. The two ends of the rotating rod 620 are respectively connected to both sides of the inner wall of the connecting groove 603. A second pressing block 619 is attached between the two first pressing blocks 605. A second limiting groove 617 is provided inside the second pressing block 619. A second fixed rod 613 is slidably connected to the inner wall of the second limiting groove 617. Two sliding grooves 615 are provided on the outer wall of the second fixed rod 613, and slidably connected within the sliding grooves 615. There is a slider 618, one side of which is connected to the inner wall of the second limiting groove 617. A third spring 616 is sleeved on the outer wall of the second fixing rod 613. A placement groove 602 is opened on the top of the inner wall of the fixing box 601. One side of the placement groove 602 is connected to one end of the second fixing rod 613. The two ends of the third spring 616 are respectively connected to the top of the second extrusion block 619 and the top of the inner wall of the placement groove 602. The outer wall of the positioning pin 9 is slidably connected to the inner wall of the fixing box 601. The tops of multiple fixing boxes 601 are respectively connected to the bottoms of the first box 1 and the second box 2.

[0044] The specific implementation method is as follows: By setting the fixing device 6, during container transportation, the fixing boxes 601 at the bottom of the first container 1 and the second container 2 are inserted into the outer wall of the positioning pin 9, so that the top of the positioning pin 9 contacts and presses the second pressing block 619, thereby causing the second pressing block 619 to move upward and press the third spring 616, causing the third spring 616 to compress and generate a rebound force. Then, the upward movement of the second pressing block 619 presses the first pressing blocks 605 on both sides, causing the first pressing blocks 605 on both sides to move inward, thereby causing the first pressing blocks 605 to drive one end of the connecting rod 607 to move. The connecting rod 607 rotates on the outer wall of the rotating rod 620, thereby... This causes the other end of the connecting rod 607 to move in the opposite direction, which in turn causes the connecting rod 607 to move the movable block 611. The movable block 611 then causes the fixing pin 612 to move and slide out of the fixing groove 604, thereby fixing the positioning pin 9 with the fixing pin 612. This avoids the need for manual fixing, thus reducing the workload of manual labor and improving work efficiency. By setting a second spring 606, when the container is moved, the rebound force of the second spring 606 causes the connecting rod 607 to reset, which in turn causes the fixed pin 612 to reset through the movable block 611, thus losing the fixing effect on the positioning pin 9. Therefore, manual release of the fixing is not required when lifting the container, improving the lifting efficiency.

[0045] An extension device 7 is connected to one side of the first housing 1. The extension device 7 includes a connecting box 701. A motor 711 is fixedly installed on the top of the inner wall of the connecting box 701. The output shaft of the motor 711 is connected to a first bevel gear 703. A second bevel gear 704 meshes with one side of the first bevel gear 703. A rotating rod 710 is connected to one side of the second bevel gear 704. A connecting rod 705 is connected to the end of the rotating rod 710 away from the second bevel gear 704. A threaded rod 706 is connected to the end of the connecting rod 705 away from the rotating rod 710. The end of 706 away from the connecting rod 705 is connected to a limiting plate 707. The outer wall of the threaded rod 706 is threadedly connected to a threaded seat 708. The outer wall of the connecting rod 705 is rotatably connected to a fixing block 709. The side of the connecting box 701 is connected to a fixing plate 702. The fixing plate 702 is embedded with a bearing, and the inner wall of the bearing is rotatably connected to the outer wall of the rotating rod 710. The side of the connecting box 701 is connected to the side of the first box 1. The top of the fixing block 709 is connected to the bottom of the first box 1. The top of the threaded seat 708 is connected to the bottom of the second box 2.

[0046] The specific implementation method is as follows: By setting up the extension device 7, the output shaft of the motor 711 drives the first bevel gear 703 to rotate, the first bevel gear 703 drives the second bevel gear 704 to rotate, the second bevel gear 704 drives the rotating rod 710 to rotate, the rotating rod 710 drives the connecting rod 705 to rotate, and the connecting rod 705 drives the threaded rod 706 to rotate, so that the threaded rod 706 drives the threaded seat 708 to move, and the threaded seat 708 drives the second box 2 to move, thereby making the second box 2 more convenient to expand. By setting up the limiting plate 707, the threaded seat 708 is prevented from sliding out of the threaded rod 706 excessively, which would affect the use of the container. By setting the connecting rod 705 to rotate within the fixed block 709, the connecting rod 705 is prevented from shaking during rotation due to being too long, thereby improving stability.

[0047] Working principle: When the container needs to be expanded, the motor 711 drives the first bevel gear 703 to rotate, which in turn drives the second bevel gear 704 to rotate. The second bevel gear 704 then drives the rotating rod 710 to rotate. The rotating rod 710, through the connecting rod 705, drives the threaded rod 706 to rotate. The threaded rod 706 drives the threaded seat 708 to move, which in turn drives the second container 2 to move. The second container 2 then drives the expansion frame 3 to move, thus expanding the volume within the first container 1 and the second container 2. During the movement of the expansion frame 3, the sealing strip 501 disengages from its original insertion into the sealing groove 8. Simultaneously, the sealing groove 8 presses the sealing strip 501 upwards, causing the sealing strip 501 to move the moving plate 506. As the moving plate 506 moves, it presses the first spring 507, causing the first spring 507 to generate a rebound force. When the expansion frame 3 is in place, the stored elasticity of the first spring 507 then allows the first... Spring 507 drives movable plate 506 to reset. The reset of movable plate 506 drives sealing strip 501 to move in the opposite direction, thereby allowing sealing strip 501 to be inserted and sealed with the expanded sealing groove 8 to prevent leakage during use. Finally, when loading and transporting the container, the fixing box 601 at the bottom of the first box 1 and the second box 2 is fitted into the positioning pin 9, thereby causing the positioning pin 9 to press the second pressing block 619. The second pressing block 619 presses the first pressing blocks 605 on both sides, causing the first pressing blocks 605 to move inward and drive the connecting rod 607 to move inward. The connecting rod 607 rotates on the outer wall of the rotating rod 620, causing the other end of the connecting rod 607 to move in the opposite direction, thereby causing the connecting rod 607 to drive the movable block 611 to move. The movable block 611 drives the fixing pin 612 to slide the groove 615 to fix the groove 604, thereby limiting and fixing the positioning pin 9, thus avoiding manual fixing after loading and improving work efficiency.
