Description

Technical Field

[0001] This utility model relates generally to the technical field of container structures, and more specifically to a container door structure and a container. Background Technology

[0002] Existing container door locks are mostly external structures, typically installed on the outside of the container. When the door is closed, the lock is secured by the mechanical engagement between the lock head and the lock seat. This design is suitable for conventional operating scenarios. However, due to the complex and diverse environments in which containers are used, in certain special conditions, such as confined spaces, narrow areas, areas lacking standing space, or areas with external obstacles, operators cannot access the door lock from the outside of the container, making the opening and closing of the door difficult. In such cases, traditional external locks, relying on external operating paths, cannot meet actual usage needs, revealing technical limitations in operational adaptability. There is an urgent need to develop new door lock structures with internal operating functions to improve the operational safety and flexibility of containers in complex environments.

[0003] Therefore, there is a need to provide a door structure and a container to at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the first aspect of this utility model provides a cabinet door structure, the cabinet door structure comprising: A door frame assembly having an outer surface and an inner surface opposite to each other along a first direction, the door frame assembly forming a door opening; A folding door assembly, one end of which is rotatably connected to a door frame assembly in a closed position and an open position about a first axis perpendicular to a first direction, wherein the folding door assembly in the closed position closes the door opening, and the folding door assembly in the open position protrudes from the outer surface to open the door opening; the folding door assembly includes a folding door body and a lock seat, the lock seat being connected to the inner side of the folding door body; and A lever lock assembly includes a lever and a lock head. The lever extends in a direction parallel to a first axis and is located on the inner surface facing away from the outer surface in the first direction. The lever is rotatably connected to the door frame assembly about a second axis parallel to the first axis. The lock head is fixed to the lever and is correspondingly arranged with the lock seat. The lock head can rotate with the lever to lock into or out of the lock seat when the flip door assembly is in the closed position.

[0006] According to the container door structure of the first aspect of this utility model, the hinged door assembly is installed to the door frame assembly by a rotatable connection, facilitating operation from inside the container to open and close the hinged door assembly. By placing the lock seat inside the hinged door body and arranging the locking rod of the lever lock assembly on the inner surface of the door frame assembly facing away from the outer surface, it is easy to lock and unlock the hinged door assembly from inside the container. Locking and unlocking the hinged door assembly is achieved by rotating the locking rod. When the hinged door assembly is in the closed position, rotating the locking rod drives the lock head to move. When the lock head engages with the lock seat, the hinged door assembly is locked, preventing it from being opened. When the lock head disengages from the lock seat, the hinged door assembly is unlocked, allowing it to be opened. By adopting the above solution, when applied to a container, the hinged door assembly can be opened and closed from inside the container without needing to be operated from outside the door, thus enhancing its adaptability to special working conditions such as confined spaces, narrow areas, areas lacking standing space, or areas with external obstacles.

[0007] Optionally, the door frame assembly has an upper end and a lower end that are opposite in the vertical direction, the vertical direction being perpendicular to the first direction, the first axis being located at the upper end of the door frame assembly, the first axis being perpendicular to the vertical direction, and the second axis being located below the first axis.

[0008] Optionally, the locking bar is located at the lower end of the door frame assembly.

[0009] Optionally, the lever lock assembly further includes a lever seat connected to the inner surface of the door frame assembly, and the lock lever is rotatably connected to the lever seat.

[0010] Optionally, the door frame assembly includes two sets of uprights spaced apart along a second direction, the second direction being perpendicular to the first direction and the vertical direction; The number of pole seats is two sets, and the two sets of pole seats are respectively fixed to the two sets of columns; The lock head is located between the two sets of the rod seats.

[0011] Optionally, the lever lock assembly further includes an operating handle connected to the locking lever.

[0012] Optionally, the door structure further includes a door hinge located on the outside of the flip door assembly; The folding door assembly has a first receiving groove adapted to receive the door hinge, and the door hinge is connected to the folding door assembly at a position corresponding to the first receiving groove; The door frame assembly has a second receiving groove adapted to receive the door hinge, and the door hinge is connected to the door frame assembly at a position corresponding to the second receiving groove.

[0013] Optionally, the folding door assembly further includes a sealing strip, which is disposed around the outer periphery of the folding door body and is adapted to seal against the door frame assembly when the folding door assembly is in the closed position; and / or The flip-door assembly also includes a handle, which is located inside the flip-door body and connected to the flip-door body. The handle is spaced apart from the first axis.

[0014] Optionally, the door structure further includes a damping limiting rod, which is constructed as a telescopic rod-shaped structure, with one end of the damping limiting rod hinged to the door frame assembly and the other end hinged to the flip door assembly.

[0015] The second aspect of this utility model provides a container, which includes the aforementioned door structure.

[0016] According to the second aspect of this utility model, by applying the aforementioned door structure, the hinged door assembly can be opened simply by operating from inside the container, thereby enhancing its adaptability to special working conditions such as confined spaces, narrow areas, areas lacking standing space, or areas with external obstacles. Furthermore, compared to technical solutions that place structures such as locking bars on the outside of the container, this reduces the compression of the internal space while ensuring that the material does not extend beyond the outer surface of the corner fittings, thus helping to increase the internal volume of the container.

[0024] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0025] Most existing container door locks are installed on the outside of the container. When the door is opened or closed, the lock head 132 at the end aligns with the lock seat 122 and engages to lock the door. However, due to the different operating environments of containers, the opening and closing of some doors cannot be achieved from the outside.

[0026] To at least partially solve the above problems, this utility model provides a door structure 100 and a container. See below. Figures 1 to 4 The examples shown provide a detailed description of the door structure 100 and the container according to the present invention.

[0027] See Figures 1 to 4 An embodiment of this utility model provides a box door structure 100. The box door structure 100 includes a door frame assembly 110, a flip door assembly 120, and a rod lock assembly 130.

[0028] The door frame assembly 110 has an outer surface 111 and an inner surface 112 that are opposite in the first direction D1. The door frame assembly 110 forms a door opening 113.

[0029] One end of the folding door assembly 120 is rotatably connected to the door frame assembly 110 about a first axis AX1 in a closed position and an open position. The first axis AX1 is perpendicular to a first direction D1. In the closed position, the folding door assembly 120 closes the door opening 113. In the open position, the folding door assembly 120 protrudes from the outer surface 111 to open the door opening 113. The folding door assembly 120 includes a folding door body 121 and a lock seat 122. The lock seat 122 is connected to the inside of the folding door body 121.

[0030] The lever lock assembly 130 includes a locking lever 131 and a lock head 132. The locking lever 131 extends in a direction parallel to a first axis AX1. The locking lever 131 is located on the side of the inner surface 112 facing away from the outer surface 111 along a first direction D1. The locking lever 131 is rotatably connected to the door frame assembly 110 about a second axis AX2. The second axis AX2 is parallel to the first axis AX1. The lock head 132 is fixed to the locking lever 131. The lock head 132 is arranged correspondingly to the lock seat 122. The lock head 132 can rotate with the locking lever 131 to lock onto or disengage from the lock seat 122 when the door assembly 120 is in the closed position. The lock head 132 locked onto the lock seat 122 prevents the door assembly 120 from moving to the open position. The lock head 132 disengaged from the lock seat 122 allows the door assembly 120 to move to the open position.

[0031] With the door assembly 120 in the closed position, the lock head 132 is moved by rotating the lock rod 131. When the lock head 132 moves to the position where it locks into the lock seat 122 on the door assembly 120, the lock rod assembly 130 and the door assembly 120 are locked together, thereby locking the door assembly 120 and the door frame assembly 110 together and keeping the door assembly 120 in the closed position.

[0032] With the door assembly 120 in the closed position and the lock head 132 locked to the lock seat 122, the lock head 132 is moved by rotating the lock lever 131. When the lock head 132 moves to the position where it is disengaged from the lock seat 122 on the door assembly 120, the lever lock assembly 130 and the door assembly 120 can be unlocked, thereby allowing the door assembly 120 to be operated to move to the open position, and thus opening the door assembly 120 and opening the doorway 113.

[0033] With the door assembly 120 in the open position, objects or goods can pass through the open doorway 113.

[0034] According to the embodiment of the present invention, the door structure 100 of the box door is rotatably connected to the door frame assembly 110, which facilitates operation from inside the box to open and close the door assembly 120. By placing the lock seat 122 inside the door body 121 and arranging the locking rod 131 of the rod lock assembly 130 on the side of the inner surface 112 of the door frame assembly 110 facing away from the outer surface 111, it is convenient to lock and unlock the door assembly 120 from inside the box. The locking and unlocking of the hinged door assembly 120 is achieved by rotating the locking lever 131. When the hinged door assembly 120 is in the closed position, rotating the locking lever 131 drives the lock head 132 to move. When the lock head 132 is locked into the lock seat 122, the hinged door assembly 120 is locked, thus preventing it from being opened. When the lock head 132 disengages from the lock seat 122, the hinged door assembly 120 is unlocked, allowing it to be opened. By adopting the above solution, when applied to a container, the hinged door assembly 120 can be opened and closed from inside the container without needing to be operated from outside. This enhances its adaptability to special working conditions such as confined spaces, narrow areas, areas lacking standing space, or areas with external obstacles. Meanwhile, the locking bar 131 is located on the side of the inner surface 112 of the door frame assembly 110 that faces away from the outer surface 111. This means that the locking bar 131 is located on the side of the door frame assembly 110 that is suitable for facing the interior space of the container. Compared with setting the locking bar 131 and the like on the outside of the door frame assembly 110, it can reduce the space occupation of the locking bar assembly 130 and the end wall or side wall as a whole on the interior space of the container, without having to move the end wall or side wall closer to the container, provided that the requirement of not exceeding the outer surface 111 of the corner fitting is met.

[0035] When the door structure 100 is applied to a container, the first direction D1 is a horizontal direction parallel to the horizontal plane, such as the width direction or the length direction of the container.

[0036] See Figures 1 to 3 In some embodiments, the door frame assembly 110 has an upper end and a lower end opposite to each other along the vertical direction D3. The vertical direction D3 is perpendicular to the first direction D1. The first axis AX1 is located at the upper end of the door frame assembly 110. The first axis AX1 is perpendicular to the vertical direction D3. The second axis AX2 is located below the first axis AX1. When the door structure 100 is applied to a container, the vertical direction D3 is the height direction of the container. Since the first axis AX1 is located at the upper end of the door frame assembly 110 and is perpendicular to the vertical direction D3, this means that the opening and closing of the flip door assembly 120 can be achieved by pushing and pulling the lower part of the flip door assembly 120. When the flip door assembly 120 is in the open position, it can provide a certain degree of protection against rain and other hazards to the door opening 113.

[0037] Furthermore, the locking rod 131 is located at the lower end of the door frame assembly 110. By placing the locking rod 131 at the lower end of the door frame assembly 110, compared to placing the locking rod 131 at a position between the upper and lower ends of the door frame assembly 110, it is possible to reduce or prevent the locking rod 131 from occupying the position of the door opening 113, thereby preventing the locking rod 131 from interfering with objects or goods entering or leaving the door opening 113. Moreover, with the locking rod 131 located at the lower end of the door frame assembly 110, the distance between the locking rod 131 and the first axis AX1 is greater, thus the locking force that the rod lock assembly 130 needs to apply to the flip door assembly 120 can be reduced, which is beneficial to reducing the requirements for the connection structure strength between the rod lock assembly 130 and the door frame assembly 110, and the structural strength of the rod lock assembly 130.

[0038] See Figure 3 and Figure 4 In some embodiments, the lever lock assembly 130 further includes a lever seat 133. The lever seat 133 is connected to the inner surface 112 of the door frame assembly 110. The locking lever 131 is rotatably connected to the lever seat 133. The lever seat 133 is used to connect and support the locking lever 131; therefore, by placing the lever seat 133 on the door frame assembly 110, the lever lock assembly 130 can be reliably installed. When the door structure 100 is applied to a container, if the lever seat 133 is installed on other structures besides the door frame assembly 110, such as side walls or end walls, it is difficult to meet the corresponding connection structural strength requirements compared to arranging the lever seat 133 on the door frame assembly 110. Since the door structure 100 is applied to a container, the door frame assembly 110 is embedded in the corresponding hole opened in the end wall or side wall. As a result, the end wall or side wall and the door frame assembly 110 overlap in wall thickness, making it difficult for the door frame assembly 110 to provide sufficient mounting surface on both sides of the second direction D2. Therefore, by arranging the rod seat 133 on the inner surface 112 of the door frame assembly 110, a reliable connection between the rod seat 133 and the door frame assembly 110 can be achieved.

[0039] Furthermore, the door frame assembly 110 includes two sets of uprights 114 spaced apart along a second direction D2. The second direction D2 is perpendicular to the first direction D1 and the vertical direction D3. There are two sets of rod seats 133. The two sets of rod seats 133 are respectively fixed to the two sets of uprights 114. The lock head 132 is located between the two sets of rod seats 133. By arranging the two sets of rod seats 133 on the two sets of uprights 114 of the door frame assembly 110 and placing the lock head 132 between the two sets of rod seats 133, the application requirements of the lock seat 122 being located in the folding door assembly 120 can be accommodated.

[0040] See Figure 1 , Figure 3 as well as Figure 4In some embodiments, the lever lock assembly 130 further includes an operating handle 134. The operating handle 134 is connected to the locking lever 131. By providing the operating handle 134, it is convenient for the user to hold and apply force to rotate the locking lever 131.

[0041] Optionally, the operating handle 134 is rotatably connected to the locking rod 131 about an axis perpendicular to the locking rod 131. Correspondingly, the rod lock assembly 130 also includes a limiting seat. The limiting seat is adapted to connect to the side wall or end wall of the container. When the lock head 132 is locked to the lock seat 122, connecting the operating handle 134 to the limiting seat prevents the locking rod 131 from rotating, thereby maintaining the locked connection between the lock head 132 and the lock seat 122. When it is necessary to open the hinged door assembly 120, by separating the operating handle 134 from the limiting seat and then manipulating the operating handle 134 to rotate the locking rod 131, the lock head 132 can be disengaged from the lock seat 122. With the lock head 132 disengaged from the lock seat 122, the hinged door assembly 120 can be operated to move about the first axis AX1.

[0042] The aforementioned locking bar 131, locking seat 122, locking head 132, bar seat 133, operating handle 134, and limit seat can adopt the locking bars, locking seats, locking heads, bar seats, operating handles, and limit seats commonly used in existing containers. The specific dimensions, installation orientation, and installation position need to be adapted according to the actual application.

[0043] See Figure 1 and Figure 2 In some embodiments, the door structure 100 further includes a door hinge 140. The door hinge 140 is located outside the hinge assembly 120. The hinge assembly 120 has a first receiving groove 124 adapted to receive the door hinge 140. The door hinge 140 is connected to the hinge assembly 120 at a position corresponding to the first receiving groove 124. The door frame assembly 110 has a second receiving groove 115 adapted to receive the door hinge 140. The door hinge 140 is connected to the door frame assembly 110 at a position corresponding to the second receiving groove 115. By providing the first receiving groove 124 in the hinge assembly 120 and the second receiving groove 115 in the door frame assembly 110, the door hinge 140 can be accommodated, thereby reducing the space occupied by the door hinge 140 on the external space of the door frame assembly 110, thereby reducing the overall size of the door structure 100 along the first direction D1 when the hinge assembly 120 is in the closed position, and further contributing to reducing the compression of the internal space of the container.

[0044] See Figure 2In some embodiments, the door assembly 120 further includes a sealing strip 125. The sealing strip 125 is disposed around the outer periphery of the door body 121. The sealing strip 125 is adapted to seal against the door frame assembly 110 when the door assembly 120 is in the closed position. By providing the sealing strip 125 around the outer periphery of the door body 121, a seal between the door assembly 120 and the door frame assembly 110 is achieved when the door assembly 120 is in the closed position.

[0045] See Figures 2 to 4 In some embodiments, the flip-door assembly 120 further includes a handle 123. The handle 123 is located inside the flip-door body 121. The handle 123 is connected to the flip-door body 121. The handle 123 is spaced apart from the first axis AX1. By installing the handle 123 inside the flip-door body 121, it is convenient for a user to apply force to the flip-door assembly 120 from inside the box by holding the handle 123, thereby realizing the opening and closing operation of the flip-door assembly 120.

[0046] Continue reading Figures 2 to 4 In some embodiments, the door structure 100 further includes a damping limiting rod 150. The damping limiting rod 150 is configured as a telescopic rod structure. One end of the damping limiting rod 150 is hinged to the door frame assembly 110, and the other end is hinged to the hinged door assembly 120. The damping limiting rod 150 can limit the maximum opening angle of the hinged door assembly 120 in the open position. The damping limiting rod 150 has a damping structure that can buffer when the hinged door assembly 120 moves to the closed position, thereby preventing the hinged door assembly 120 from impacting or colliding with the hinged door assembly 120 due to inertia, and serving the purposes of shock absorption, noise reduction, and protection.

[0047] Alternatively, the damping limit rod 150 can adopt some existing structures that have damping and telescopic capabilities.

[0048] An embodiment of this utility model also provides a container. This container is, for example, a marine equipment container or the like. The container includes the aforementioned door structure 100.

[0049] According to the embodiments of this utility model, the container with the aforementioned door structure 100 allows the hinged door assembly 120 to be opened simply by operating from inside the container, thereby enhancing its adaptability to special working conditions such as confined spaces, narrow areas, areas lacking standing space, or areas with external obstacles. Furthermore, compared to technical solutions that place structures such as the locking bar 131 on the outside of the container, this reduces the compression of the internal space while ensuring that the space does not exceed the outer surface 111 of the corner fittings, thus helping to increase the internal volume of the container.

[0050] Optionally, the container has side walls and end walls. The container door structure 100 is located on the side wall or the end wall.

[0051] Preferably, the door structure 100 is located on the side wall. The end of the container is provided with a conventional door.

[0052] In a marine container, equipment and a cable winch are installed inside the container. The cable winch is connected to the equipment inside the container. With the hinged door assembly 120 open, the cable of the cable winch can pass through the door opening 113 to reach outwards, enabling connection to equipment inside another container or to equipment outside the container.

[0053] According to the container door structure 100 of this utility model and the container having it, even in confined spaces, one person can open and close the flip door assembly 120 from the inside of the door frame assembly 110. The locking rod 131, located at the lower end of the door frame assembly 110, minimizes the force required to open and close the door. Compared to container side-opening doors, which are limited by the external locking rod 131 and cannot extend beyond the corner bracket, thus compressing the internal space, the container door structure 100 of this utility model significantly compresses and enhances the internal space of the container by installing the rod lock assembly 130 inside the container.
