Description

Technical Field

[0001] This invention belongs to the field of transport vehicles, specifically a wing-opening carriage with a multi-seal structure. Background Technology

[0002] Wing-opening carriages are a special type of transport vehicle, characterized by their upward-opening side wing doors. They are typically used for transporting standardized goods and high-value or fragile items, which often require sealing for dust and moisture protection.

[0003] However, currently common wing-opening carriages often use multiple layers of rubber strips and waterproof canvas to protect the products inside the carriage. The multi-layer sealing structure is both complex and prone to failure. Alternatively, multiple layers of seals can be set at the opening and closing points, but the frequent friction of the sealing surfaces due to the opening and closing action often causes the rubber strips to fail, allowing rainwater to seep into the carriage along the opening and closing points. To prevent rainwater accumulation, drainage channels are set at the top edge of the carriage. However, when the wing panels open and close, the drainage channels are easily squeezed and deformed, causing the drainage function to fail. Moreover, it is difficult to repair after deformation. Therefore, a wing-opening carriage with a multi-layer sealing structure is proposed to solve the above technical problems. Summary of the Invention

[0004] This utility model provides a wing-opening carriage with a multi-seal structure, including a top plate, a bottom plate, a front plate, and a rear door plate that form the carriage body. A frame is set inside the carriage body, including longitudinally arranged support columns and connecting beams between the support columns. A wing door is set between the top plate and the bottom plate, and the wing door is movably connected to the carriage body. A folding handle is set at the opening and closing of the wing door. The wing door and the carriage body are connected by several flip hinges. A rain shield is set at the connection point. The rain shield is arc-shaped, and the edge of the rain shield can completely cover the flip hinges. A pivot is set at the connection point between the rain shield and the top plate. A retaining ring that can be adapted to the pivot is set at the edge of the top plate. The movable end of the rain shield can always fit against the wing door during the opening and closing process to prevent rainwater leakage.

[0005] Preferably, the wing door includes an upper wing door and a lower wing door, the width of the upper wing door is greater than the width of the lower wing door, and the rain shield is set at the connection between the upper wing door and the top plate.

[0006] Preferably, a sealing strip is provided at the connection between the top surface of the upper wing door and the top plate. The sealing strip is T-shaped at the end near the inner side of the upper wing door and L-shaped at the end near the outer side of the upper wing door, with a groove formed in the middle of the sealing strip.

[0007] Preferably, a protrusion is provided on the top plate corresponding to the closing position of the upper wing door. The protrusion corresponds to the groove in the middle of the sealing strip. When the upper wing door is closed, the protrusion and the sealing strip cooperate to form two seals, one inside and one outside.

[0008] Preferably, a plurality of buffer pads are provided in the groove of the sealing groove, and the buffer pads are elastic rubber strips with elastic protrusions at both ends.

[0009] Preferably, a lower flip-up cover is provided at the connection between the bottom inner side of the lower wing door and the base plate. The lower flip-up cover is fixed to one end of the base plate and a reset spring base is provided.

The lower flip-up cover is a driven component of the lower wing door.

[0010] Preferably, an opening and closing part is provided on the inner side of the upper wing door, and a strut connector is provided between the support column near the upper wing door. After the upper wing door is opened, a strut can be installed between the two strut connectors.

[0011] Preferably, the support columns are arranged longitudinally in pairs, and a connecting beam is provided between each pair of support columns.

[0012] Preferably, hydraulic support rods are provided on the inner sides of both the upper and lower wing doors, and the other side of the hydraulic support rods is mounted on a support column.

[0013] The beneficial effects of this utility model are as follows: This utility model solves the problems of previous waterproofing measures being both complex and prone to failure by using a rain shield and a flip-down cover. The arc-shaped rain shield and flip-down cover not only prevent rainwater penetration during use, but also quickly disperse water flow through the arc surface, preventing it from accumulating at the junction of the wing door and the body. In addition, it adopts a special type of single sealing strip. Through the raised structure on both sides, it improves the airtightness of the compartment while preventing the sealing surface from frequently rubbing and causing the sealing strip to fail due to opening and closing. This simplifies the complicated waterproofing and sealing measures, reduces maintenance costs, and greatly improves transportation efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present invention 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 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.

[0017] like Figure 1 , Figure 5 As shown, a wing-opening carriage with a multi-sealing structure includes a frame 1, a top plate 2, a bottom plate 3, a front plate 13, and a rear door plate 14. The frame 1 includes four sets of support columns 15 arranged longitudinally inside the carriage. The support columns 15 are arranged longitudinally and supported between the top plate 2 and the bottom plate 3. Two connecting beams 16 are arranged between each set of support columns 15. The connecting beams 16 provide lateral support for the support columns 15. The combination of the support columns 15 and the connecting beams 16 provides a stable internal space for the carriage. The front plate 13 and the rear door plate 14 are respectively arranged at both ends of the top plate 2 and the bottom plate 3. The front plate 13 and the rear door plate 14 are fixedly connected to the top plate 2 and the bottom plate 3 and cannot be opened or closed. They also provide a certain support for the carriage space. Openable wing doors are arranged on both sides of the top plate 2 and the bottom plate 3. The wing doors are segmented, including an upper wing door 4 and a lower wing door 5. A folding handle 11 is arranged between the upper wing door 4 and the lower wing door 5.

[0018] like Figure 2 , Figure 5 As shown, the upper wing door 4 and the lower wing door 5 are fixed to the side edges of the top plate 2 and the bottom plate 3 respectively by several flip hinges 6. The width of the upper wing door 4 is greater than the width of the lower wing door 5. Hydraulic support rods 10 are installed on the inner walls of both the upper wing door 4 and the lower wing door 5. The other side of the hydraulic support rod 10 is installed on the support column 15. The hydraulic support rod 10 can provide assistance when the wing door is opened and closed and prevent the user from being injured by gravity due to improper operation during the opening and closing process. Strut connectors 17 are installed at the opening and closing point inside the upper wing door 4 and on the outer side of the support column 15 near the wing door. After the wing door 4 is opened, a strut 18 can be installed between the two strut connectors 17. The strut connectors 17 on the support column 15, the upper wing door 4 on the same side, and the strut 18 form a stable triangular support area, which greatly increases the upper load limit after the upper wing door 4 is opened. The upper wing doors 4 on both sides expand the usable area of ​​the top of the carriage when they are opened, and the lower wing door 5 lowers to increase the support area of ​​the bottom of the carriage. When the lower wing door 5 is open, hydraulic outriggers can be installed at the edge to improve the stability of the lower wing door 5 when it is open. Ladders can be erected at both ends of the lower wing door 5.

[0019] like Figure 3As shown, the upper wing door 4 and the top plate 2 are hinged by a flip hinge 6. A rain shield 7 is installed at the hinge of the flip hinge 6. The rain shield 7 is arc-shaped, and its lower edge can completely cover the flip hinge 6. A retaining ring is installed at the edge connection of the top plate 2. A pivot is installed at the connection between the rain shield 7 and the top plate 2 to match the retaining ring. The rain shield 7 can rotate around the pivot. When the upper wing door 4 is closed, the rain shield 7 falls down to completely cover the connection between the upper wing door 4 and the top plate 2 and the flip hinge 6, preventing water from entering the connection between the upper wing door 4 and the top plate 2 and preventing the flip hinge 6 from rusting when exposed to water. When the upper wing door 4 is opened upward, the rain shield 7 can be passively raised to cover the gap of the upper wing door. The arc-shaped design of the gap between the upper wing door 4 and the top plate 2 ensures that liquid will not stagnate in the gap and seep into the interior of the carriage. A sealing strip 8 is installed on the top surface of the upper wing door 4. The sealing strip 8 is T-shaped at the inner end near the upper wing door 4 and L-shaped at the outer end near the upper wing door 4. A groove is formed in the middle of the sealing strip 8, and a protrusion is set at the closing position of the upper wing door 4. When the upper wing door 4 is closed, the protrusion and the sealing strip 8 are matched to form a double seal to prevent liquid from entering the carriage. A buffer pad 12 is set in the groove of the sealing strip 8. The buffer pad 12 is an elastic rubber strip with elastic protrusions at both ends, which can reduce the pressure that is directly applied to the sealing pad 8 when the upper wing door 4 is closed.

[0020] like Figure 4 As shown, the bottom outer side of the lower wing door 5 is hinged to the side edge of the base plate 3 via a flip hinge 6. A lower flip cover 9 is provided at the connection between the lower wing door 5 and the inner side of the base plate 3. The lower flip cover 9 is fixed to one end of the base plate 3 and has a return spring base. The other end can completely cover the gap between the lower wing door 5 and the base plate 3 when the lower wing door 5 is open. The lower flip cover 9 can cover the gap when the lower wing door 5 is open via a return spring, and can be lifted upwards when the lower wing door 5 is closed to prevent debris from entering.

[0021] When the carriage is not in use, it is closed. The rain shield 7 and sealing strip 8 at the junction of the upper wing door 4 and the roof panel 2 ensure that the interior space of the carriage is dry when in use. When in use, first pull out the folding handle 11 on the side wall of the upper wing door 4. During the pulling process, the hydraulic support rod 10 provides assistance, improving the stability during the pulling process and when fully open. When the upper wing door 4 is fully open, depending on the load-bearing capacity, the support rod connector 17 can be used to install a support rod 18 between the upper wing door 4 and the support column 15 on the same side, further increasing the load-bearing range of both sides of the upper wing door 4. The lower wing door 5 automatically descends as the upper wing door 4 opens. The hydraulic support rod 10 connected to the lower wing door 5 provides a slow centrifugal force during the opening process, so that the lower wing door 5 maintains a uniform speed during descent and also improves the stability of the lower wing door 5 after it is fully descended. For support, hydraulic outriggers can be installed on both sides after the lower wing door 5 is in place to improve the overall stability of the carriage. During the opening of the upper wing door 4, the rain shield 7 at the edge of the upper wing door 4 and the top plate 2 operates in tandem with the opening of the upper wing door 4. After the upper wing door 4 is fully opened, the rain shield 7 changes from a longitudinal shape to a transverse shape. The arc design prevents liquid from accumulating at the connection between the upper wing door 4 and the top plate 2, thus preventing liquid leakage into the carriage even in rainy weather. When the lower wing door 5 is opened simultaneously, the lower flip cover 9 between the lower wing door 5 and the bottom plate 3 operates downwards under the pressure of the return spring, providing a shielding function for the gap between the bottom plate 3 and the lower wing door 5, preventing the flip hinge 6 between the lower wing door 5 and the bottom plate 3 from getting wet and rusting.
