Description

Technical Field

[0001] This utility model relates to the field of container technology, and more specifically to a multi-door container. Background Technology

[0002] Containers are a commonly used transportation tool in modern logistics. Depending on the type of cargo transported, containers can be divided into general cargo containers and specialized containers such as bulk cargo containers. Traditional general cargo containers typically use a "double-door" structure, while bulk cargo containers use a "top-opening door" structure. With the need for cost reduction and efficiency improvement in the logistics and transportation industry, enhancing the cargo applicability of containers has become one solution, enabling them to transport both general cargo and bulk cargo.

[0003] The aforementioned "double-door" design occupies a large space when open and is not convenient for loading and unloading certain goods; while the "top-opening door" is easy to open, its opening degree is limited when the container door needs to be fully opened.

[0022] Now, refer to Figures 1 to 9 Exemplary embodiments according to the present invention will be described in more detail below.

[0023] refer to Figure 1 This application provides a multi-door container 100, which includes a door end 101, a double-door assembly 110, a side-opening door assembly 120, and an upward-opening door assembly 140. The door end 101 has two corner posts extending along the height direction of the multi-door container 100. The double-door assembly 110 includes a first door leaf 111 and a second door leaf 113 arranged along the width direction of the multi-door container 100, wherein the first door leaf 111 and the second door leaf 113 are respectively pivotally connected to the two corner posts. The side-opening door assembly 120 is disposed below the double-door assembly 110, and one end of the side-opening door assembly 120 along the width direction is pivotally connected to one corner post. The upward-opening door assembly 140 is disposed on the side-opening door assembly 120, and the upper end of the upward-opening door assembly 140 along the height direction is pivotally connected to the side-opening door assembly 120.

[0024] According to the multi-door container 100 of this application, by combining various types of doors, it is possible to open each door individually or all doors at the same time, which can meet the needs of different application scenarios. The door end 101 also has a fixed lintel beam 104 and a threshold beam 105, wherein the fixed lintel beam 104 is located at the upper end of the door end 101 and the threshold beam 105 is located at the lower end of the door end 101. A double door assembly 110 is disposed below the fixed lintel beam 104, and a side door assembly 120 and an upward-opening door assembly 140 are disposed above the threshold beam 105.

[0025] The two corner posts of the door end 101 are a first corner post 102 and a second corner post 103. The first door leaf 111 is pivotally connected to the first corner post 102 via a first pivot 117. More specifically, the first door leaf 111 has a first door vertical beam 112, which is pivotally connected to the first side post 122 at the first corner post 102. The second door leaf 113 is pivotally connected to the second corner post 103 via the first pivot 117. More specifically, the second door leaf 113 has a second door vertical beam 114, which is pivotally connected to the second corner post 103. Thus, the first door leaf 111 and the second door leaf 113 can pivotally open outwards.

[0026] The first door vertical beam 112 extends vertically above the side-opening door assembly 120. The second door vertical beam 114 extends vertically to the sill beam 105, and part of the second door vertical beam 114 is located to the side of the side-opening door assembly 120. In other words, the second door vertical beam 114 is located between the second corner post 103 and the side-opening door assembly 120.

[0027] refer to Figure 1 , Figure 2 and Figure 4 The side-opening door assembly 120 includes a first side post 122, a second side post 123, and a movable lintel 121. The first side post 122 and the second side post 123 are spaced apart along the width direction, and the movable lintel 121 connects the first side post 122 and the second side post 123. In other words, the first side post 122 and the second side post 123 are respectively connected to both ends of the movable lintel 121. The upward-opening door assembly 140 is pivotally connected to the movable lintel 121.

[0028] The double door assembly 110 also includes a first locking rod assembly 115 and a first operating lever 118, which are disposed on the first door leaf 111 and the second door leaf 113. The first locking rod assembly 115 extends along the height direction, and the first operating lever 118 is connected to the first locking rod assembly 115 and extends along the width direction. A first lock seat assembly 116 is disposed on the fixed lintel beam 104 and the movable lintel beam 121. When the double door assembly 110 is closed, the first locking rod assembly 115 can lock with the first lock seat assembly 116.

[0029] The first side post 122 is pivotally connected to the first corner post 102, specifically, the first side post 122 is pivotally connected to the first corner post 102 via a second pivot part 125. This allows the second side post 123 to pivotally open outwards. The second side post 123 is provided with a first blocking member 124. When the double door assembly 110 is in the closed and locked state, the first blocking member 124 is located inside the first door leaf 111 or the second door leaf 113, preventing the double door assembly 110 from opening the side door assembly 120. In this embodiment, when both the side door assembly 120 and the double door assembly 110 are in the closed state, the first blocking member 124 extends to the inside of the second door vertical beam 114.

[0030] It is understandable that when the double door assembly 110 is closed and locked, because the second door vertical beam 114 of the second door leaf 113 is located outside the first blocking member 124, it prevents the second side post 123 from pivoting outward, thus keeping the side door assembly 120 locked as well. That is, the side door assembly 120 cannot be opened independently; it needs to be opened only after the double door assembly 110 has been opened. Figure 7 , Figure 8 and Figure 9 As shown, when the application scenario requires the door end 101 to be fully opened, the first door leaf 111 can be opened first, then the second door leaf 113, and then the side-opening door assembly 120 can be opened. At the same time, since the upward-opening door assembly 140 is set on the side-opening door assembly 120, it is also opened at the same time.

[0031] As one implementation, refer to Figure 1 , Figure 2 and Figure 3 A second blocking member 130 is provided on the side of the second corner post 103 facing the first corner post 102. When both the side door assembly 120 and the double door assembly 110 are in the closed state, the first blocking member 124 is located between the second door vertical beam 114 and the second blocking member 130.

[0032] More specifically, the second blocking member 130 includes a first limiting portion 131 and a second limiting portion 132. The first limiting portion 131 is connected to the second corner post 103, and the second limiting portion 132 is connected to the end of the first limiting portion 131 away from the second corner post 103 and spaced apart from the second corner post 103, extending upwards in the height direction. When both the side-opening door assembly 120 and the double-opening door assembly 110 are closed, the first blocking member 124 is located above the first limiting portion 131 and between the second limiting portion 132 and the second corner post 103. Thus, the second blocking member 130 can form an obstacle to the inward movement of the side-opening door assembly 120. The second blocking member 130, the second corner post 103, and the second door vertical beam 114 can combine to form a space to accommodate the first blocking member 124, thereby achieving locking and limiting of the side-opening door assembly 120.

[0033] Please refer to the following. Figure 1 , Figure 5 and Figure 6 The upward-opening door assembly 140 specifically includes an upward-opening door leaf 141, a second locking rod assembly 142, and a second operating rod 147. The upward-opening door leaf 141 is located between the first side post 122 and the second side post 123. The upper end of the upward-opening door leaf 141 is pivotally connected to the movable lintel beam 121, specifically, the upward-opening door leaf 141 is pivotally connected to the movable lintel beam 121 via a third pivot part 146.

[0034] The second locking rod assembly 142 is disposed on the upward-opening door leaf 141 and extends along its width. The first side post 122 and the second side post 123 are provided with second lock seat assemblies 143. When the upward-opening door leaf 141 is closed, the second locking rod assembly 142 can lock with the second lock seat assembly 143. The second operating rod 147 extends perpendicular to the second locking rod assembly 142 and is connected to it. In a preferred embodiment, the movable lintel beam 121 is provided with a clearance portion 126 to accommodate the second operating rod 147. Exemplarily, the clearance portion 126 may be configured as an upwardly convex triangle.

[0035] In one preferred embodiment, a hook 144 is provided on the movable lintel 121, and a hanging rope 145 is provided on the second locking rod assembly 142, such as... Figure 6 As shown, when the lift-up door 141 is opened, the hanging rope 145 can be connected to the hook 144, thereby enabling the lift-up door 141 to be continuously opened.

[0036] In summary, the top-hinged door assembly 140 can be opened individually, the double-door assembly 110 can be opened individually, and the double-door assembly 110 and the side-opening door assembly 120 can be opened simultaneously. Therefore, the multi-door container 100 of this application can adapt to different scenarios. For example, the top-hinged door opening alone can adapt to bulk cargo transportation scenarios, while the simultaneous opening of the double-door assembly 110 and the side-opening door assembly 120 will fully open the door end 101, thus adapting to the transportation scenarios of general goods, such as dry goods and large-sized goods.
