Description

Technical Field

[0001] This utility model relates to the field of side curtain carriage technology, specifically, to a side curtain carriage with a double-door structure. Background Technology

[0002] Curtain-side vans, also known as curtain vans, are a special type of van with curtain structures on one or both sides. Curtain-side vans with double-door structures have multiple double-door side doors inside the curtain, dividing the side of the van into several sections. Each section corresponds to a set of double-door rigid doors. This retains the loading and unloading flexibility of curtain-side vans while enhancing protection and sealing through the double-door structure of the rigid doors. In the prior art, before loading goods, the curtains of a side-curtain carriage with a double-door structure need to be fully "opened," with one end of the curtain pulled from one side of the carriage to the other, the movement distance being close to the length of the carriage. The curtain is then fixed, and the double doors are opened. This can prevent one end of the curtain from obscuring the carriage during loading, thus avoiding affecting the loading process. However, the "double doors" on the side of the curtain carriage are multi-segmented, forming multiple small carriages that evenly divide the side of the carriage. If the goods cannot fill the entire carriage, they can be loaded into one or more small carriages. However, the entire curtain still needs to be "rolled up" during loading, making it difficult to adjust the curtain movement according to the amount of goods to be loaded, thus connecting and fixing the corresponding small carriages to the outside. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a side curtain carriage with a double-door structure, which solves the technical problem in the prior art that the entire curtain still needs to be "rolled up" when loading goods, making it difficult to move the curtain a corresponding distance according to the amount of goods to be loaded, so that the corresponding multiple small carriages can be connected to the outside and fixed.

[0004] According to one aspect, at least one embodiment of the present invention provides a side-curtain carriage with a double-door structure, including a carriage body, on which multiple sets of double-door frames are hinged, and further including a fixed frame, a movable plate, a baffle plate, and a limiting component. The fixed frame is fixedly connected to both sides of the carriage body and has a receiving cavity for receiving the curtain fabric. The movable plate is slidably disposed within the fixed frame and fixedly connected to the other end of the curtain fabric. The baffle plate is fixedly connected to one side of the door frame near the receiving cavity among the multiple sets of double-door frames. The fixed frame has a slot that cooperates with the baffle plate for cooperating with the door frame to rotate and pass through the slot to abut against the movable plate. The limiting component is disposed on the fixed frame for fixing the baffle plate and the door frame after the movable plate abuts against the baffle plate.

[0005] Preferably, in order to ensure that the movable plate can be stably slidably disposed within the fixed frame, the length of the movable plate is greater than the length of the curtain, and a sliding groove that cooperates with the movable plate is provided in the fixed frame, and the sliding groove is inclined.

[0006] Furthermore, in order to fix the movable plate to the fixed frame when the curtain is unfolded or in the receiving cavity to prevent the curtain from moving, threaded holes are provided at both ends of the fixed frame, and the fixed frame and the movable plate are detachably connected by locking bolts.

[0007] Furthermore, in order to allow the baffle plate to be inserted into the sliding groove under the rotation of the door frame and block the movement of the moving plate, the baffle plate is set on the lower side of the door frame through a connecting plate. Both the baffle plate and the connecting plate are arc-shaped. The fixed frame is provided with a through groove that cooperates with the connecting plate, and the moving plate is provided with an abutment groove that cooperates with the baffle plate.

[0008] As a further aspect of this application, in order for the movable plate to move the curtain out of the receiving cavity when the door frame is closed (not rotated) and to seal the side of the carriage body to avoid being blocked by the baffle, the baffle is provided with a through opening that cooperates with the movable plate.

[0009] As a further embodiment of this application, the limiting component includes a protruding plate and a limiting hemisphere. The protruding plate is fixed on the fixed frame, and a moving groove is formed on the protruding plate. The limiting hemisphere is elastically disposed within the protruding plate, and a limiting hole that cooperates with the limiting hemisphere is formed on the connecting plate.

[0010] Based on the aforementioned scheme, a pressing plate is slidably arranged in the moving groove, a connecting spring is provided between the moving plate and the inner wall of the moving groove, and the moving plate is fixedly connected to the limiting hemisphere.

[0011] Furthermore, to prevent the limiting hemisphere from moving excessively and out of the moving groove under the elastic force of the connecting spring, the cross-sectional area of ​​the moving plate is larger than the cross-sectional area of ​​the limiting hemisphere.

[0012] The beneficial effects of this utility model are as follows: In this invention, when loading cargo into the carriage body, the corresponding double-leaf door frame that needs to be "opened" is selected according to the space occupied by the cargo. By tightening the locking bolts and removing them, the handle is used to move the moving plate toward the receiving cavity, releasing the door frame's latching structure. Rotating the door frame causes the connecting plate and the partition plate to rotate, and the limiting hemisphere engages in the limiting groove. One end of the partition plate is inserted into the slot and is in the sliding groove. The moving plate, under the tilting sliding groove and its own gravity, abuts against the partition plate, thus maintaining the stability of the door frame and the connecting plate. This allows the door frame to be opened for easy loading, and the curtain is fixed in the fixed frame without affecting loading. After loading is completed, the door frame is rotated vigorously to cause the connecting plate to rotate in the opposite direction and squeeze the limiting hemisphere, so that the partition plate returns to its initial position, making it easy for the curtain to seal the side of the carriage body.

[0021] like Figures 1-7 As shown, it illustrates a side curtain carriage with a double-door structure in one embodiment of the present invention, including a carriage body 1, with multiple sets of double-door frames 2 hinged on the carriage body 1, each set of double-door frames 2 including two door frames 2, and also including a fixed frame 4, a movable plate 7, a baffle plate 8 and a limiting component. like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the fixed frame 4 is fixedly connected to both sides of the carriage body 1 and has a receiving cavity 5 for accommodating the curtain 6. The curtain 6 is retractable. One end of the curtain 6 is fixedly connected to the inner wall of the receiving cavity 5. The movable plate 7 is slidably disposed in the fixed frame 4 and is fixedly connected to the other end of the curtain 6. In order to keep the movable plate 7 stable in the fixed frame 4, the length of the movable plate 7 is greater than the length of the curtain 6. The fixed frame 4 has a sliding groove 11 that cooperates with the movable plate 7. The sliding groove 11 is inclined and the receiving cavity 5 is at a "high position". The two ends of the movable plate 7 are respectively engaged in the two sliding grooves 11 and slide in cooperation with the sliding grooves 11. A handle 23 is fixedly connected to the movable plate 7. By holding the handle 23, the movable plate 7 is moved along the inner wall of the sliding groove 11 in the direction away from the receiving cavity 5. And because the fixed frame 4 is inclined, the movable plate 7 is more convenient to move away from the receiving cavity 5. In this way, the curtain 6 is unfolded and the side of the carriage body 1 is sealed. It should be added that multiple columns 3 are provided inside the carriage body 1 for installing door frames 2, so that the door frames 2 are hinged in the fixed frame 4, and the door frames 2 can be detachably fixed in the fixed frame 4 through a buckle structure. To prevent the curtain 6 from moving, the movable plate 7 can be fixed to the fixed frame 4 when the curtain 6 is unfolded or inside the receiving cavity 5. Threaded holes 12 are provided at both ends of the fixed frame 4. The fixed frame 4 and the movable plate 7 are detachably connected by locking bolts 13. In the initial state, the locking bolts 13 are located close to the receiving cavity 5 and the curtain 6 is inside the receiving cavity 5. After turning and removing the locking bolts 13, the curtain 6 is pulled out and the side of the carriage body 1 is sealed. When the movable plate 7 is at the other end of the fixed frame 4, the locking bolts 13 are used again to fix the movable plate 7 to the fixed frame 4. The baffle plate 8 is fixedly connected to one side of the door frame 2 closest to the receiving cavity 5 in the multiple sets of double-leaf door frames 2. In order to allow the movable plate 7 to move the curtain 6 out of the receiving cavity 5 when the door frame 2 is closed (not rotated) and to seal the side of the carriage body 1, so as to avoid being blocked by the baffle plate 8. The baffle plate 8 is provided with a through hole 16 that cooperates with the movable plate 7. Specifically, before the curtain 6 is pulled out and the side of the carriage body 1 is sealed, the door frame 2 is fixed in the fixed frame 4 by a buckle structure. The door frame 2 drives the baffle plate 8 to rotate and is in the fixed frame 4. At this time, the through hole 16 is connected to the slide 11. When the handle 23 moves the movable plate 7, the movable plate 7 can continue to move through the through hole 16 to seal the side of the carriage body 1. like Figure 6 and Figure 7 As shown, the fixed frame 4 has a slot 10 that mates with the baffle plate 8. This slot allows the door frame 2 to rotate and pass through the slot 10 to abut against the movable plate 7. To allow the baffle plate 8 to insert into the sliding groove 11 and block the movement of the movable plate 7 when the door frame 2 rotates, the baffle plate 8 is mounted on the lower side of the door frame 2 via a connecting plate 9. Both the baffle plate 8 and the connecting plate 9 are arc-shaped. The fixed frame 4 has a through groove 14 that mates with the connecting plate 9, and the movable plate 7 has an abutment groove 15 that mates with the baffle plate 8. When the door frame 2 is not rotating, the baffle plate 8 is located at the connection between the through groove 14 and the sliding groove 11. When loading is required, the baffle plate 8 is "opened" according to the space occupied by the goods. "Several double-leaf door frames 2, by tightening the locking bolts 13, the hand handle 23 drives the moving plate 7 to move into the receiving cavity 5. During the movement, the curtain 6 rolls up and opens multiple double-leaf door frames 2 (two door frames 2) in sequence. Each double-leaf door frame 2 is equivalent to the space of a small carriage. When the required multiple small carriages are not sealed by the curtain 6, the moving plate 7 is between the receiving cavity 5 and the corresponding slot 10. By releasing the buckle structure of the door frame 2, the door frame 2 is rotated to drive the connecting plate 9 and the partition plate to rotate. One end of the partition plate 8 is inserted into the slot 10 and is in the slide 11. The moving plate 7, under the action of tilting the slide 11 and its own gravity, abuts against the partition plate 8." A limiting component is mounted on the fixed frame 4 to fix the baffle 8 and the door frame 2 after the movable plate 7 abuts against the baffle 8. The limiting component includes a protruding plate 17 and a limiting hemisphere 19. The fixed frame 4 has a protruding plate 17, one end of which is arc-shaped and slides against the side wall of the connecting plate 9. A moving groove 18 is provided on the protruding plate 17. The limiting hemisphere 19 is elastically disposed within the protruding plate 17 and is positioned above the baffle 8. A limiting hole 20 is provided on the connecting plate 9 to mate with the limiting hemisphere 19. A pressing plate 21 is slidably disposed within the moving groove 18. A connecting spring 22 is provided between the pressing plate 21 and the inner wall of the moving groove 18. The pressing plate 21 is fixedly connected to the limiting hemisphere 19. To prevent the limiting hemisphere 19 from moving excessively and moving out of the moving groove 18 under the elastic force of the connecting spring 22, the cross-sectional area of ​​the pressing plate 21 is larger than the cross-sectional area of ​​the limiting hemisphere 19. When the connecting plate 9 and the baffle plate 8 rotate, the arc-shaped sidewall of the connecting plate 9 presses against the limiting hemisphere 19. The limiting hemisphere 19 drives the pressing plate 21 to press against the connecting spring 22. The connecting spring 22 contracts, and under the pressure of the connecting plate 9, the limiting hemisphere 19 moves into the moving groove 18. When the limiting hole 20 is connected to the limiting hemisphere 19, the limiting hemisphere 19 and the pressing plate 21 are pushed by the elastic force of the connecting spring 22, and the limiting hemisphere 19 is inserted into the limiting groove. At this time, the connecting plate 9 drives one end of the baffle plate 8 to be in the sliding groove 11 and abuts against the pressing plate 21. This keeps the door frame 2 and the connecting plate 9 stable, which can open the door frame 2 for easy loading, and fix the curtain 6 in the fixed frame 4 without affecting loading. After loading is completed, the door frame 2 is rotated vigorously to drive the connecting plate 9 to rotate in the opposite direction to press against the limiting hemisphere 19, so that the baffle plate 8 returns to the initial position, which makes it easy for the curtain 6 to seal the side of the carriage body 1. Working principle: When loading cargo, the side curtain compartment of this double-door structure selects the corresponding double-door frame 2 to be "opened" according to the space occupied by the cargo. By tightening the locking bolt 13, the handle 23 is used to move the moving plate 7 towards the receiving cavity 5. During the movement, the curtain 6 rolls up and opens multiple double-door frames 2 (two door frames 2) in sequence. When the required multiple compartments are not sealed by the curtain 6, the moving plate 7 is between the receiving cavity 5 and the corresponding slot 10. By releasing the latching structure of the door frame 2, the door frame 2 is rotated, causing the connecting plate 9 and the partition plate to rotate. The arc-shaped side wall of the connecting plate 9 presses against the limiting hemisphere 19. The limiting hemisphere 19 causes the oiling plate to press against the connecting spring 22. The connecting spring 22 retracts, and under the pressure of the connecting plate 9, the limiting hemisphere 19 compresses the limiting hemisphere 19. The hemisphere 19 moves into the moving groove 18. When the limiting hole 20 is connected to the limiting hemisphere 19, the limiting hemisphere 19 and the pressing plate 21 are pushed by the elastic force of the connecting spring 22. The limiting hemisphere 19 is inserted into the limiting groove. During this process, one end of the baffle plate 8 is inserted into the slot 10 and is in the sliding groove 11. The moving plate 7, under the action of tilting the sliding groove 11 and its own gravity, abuts against the baffle plate 8. This keeps the door frame 2 and the connecting plate 9 stable, which can open the door frame 2 for easy loading and fix the curtain 6 in the fixed frame 4 without affecting loading. After loading is completed, the door frame 2 is rotated vigorously to drive the connecting plate 9 to rotate in the opposite direction and press the limiting hemisphere 19, so that the baffle plate 8 returns to the initial position, which makes it easy for the curtain 6 to seal the side of the carriage body 1.
