Description

Technical Field

[0001] This utility model relates to the field of containers, and more specifically to containers. Background Technology

[0002] As the mainstream equipment in the bulk cargo transportation field, bulk cargo containers, with their standardized design and efficient loading characteristics, can meet the long-distance transportation needs of various types of bulk cargo such as grain, fruit, ore, and granular chemical raw materials.

[0003] In actual operations, the loading methods for bulk cargo containers are mainly divided into two categories: one is loading through the opening at the top of the container, and the other is loading the cargo using the door-end passageway.

[0004] However, most current mainstream bulk cargo containers have a door at one end of the container body (the door end). The door extends from the lintel to the sill. The container also includes double doors for opening or closing the door. This type of container with double doors has significant limitations in high-volume loading scenarios. When bulk cargo (such as grains, fruits, and other easily movable agricultural products) is pushed in or transferred through the door, the cargo will accumulate towards the door due to its own weight and mobility. Since the double doors are open during loading, cargo that has accumulated to a certain height will overflow from the door.

[0005] Therefore, this utility model provides a container to at least partially solve the above-mentioned problems. Utility Model Content

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0022] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0023] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not include any other meaning, such as a specific order.

[0024] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may also include other embodiments.

[0025] First Implementation Method This utility model provides a container. The container body 110 has an upper opening 117 on its vertical wall. The container also has an outer door for opening or closing the upper opening 117, and a door stop 140 for covering the lower part of the upper opening 117. The door stop 140 also has a position where the lower part of the upper opening 117 is open. The lower part of the upper opening 117 has a lower opening 118 and a lower door 150 for opening or closing the lower opening. Thus, goods can be loaded into the container body 110 through the upper opening 117, and in this case, the lower door 150 can prevent goods from leaking out.

[0026] Please refer to Figures 1 to 6 The container includes a container body 110. The container body 110 includes vertical walls, a base frame, and a top wall. The vertical walls include end walls 111 and side walls. The end walls 111, side walls, base frame, and top wall form a generally rectangular parallelepiped structure. The end walls 111 are located at the ends of the container body. The vertical walls have door frames 112. The door frame 112 includes two spaced-apart columns 113, a top beam 114, and a center beam 115. The top beam 114 is connected at both ends to the tops of the two columns 113. The center beam 115 is located below the top beam 114. The center beam 115 and the top beam 114 are spaced apart. The two ends of the center beam 115 are connected to the two columns 113. Thus, the two columns 113, the top beam 114, and the center beam 115 form a circumferentially closed, generally rectangular structure, thereby forming an upper opening 117.

[0027] like Figures 1 to 5 As shown, the container also includes a door 130. The door 130 is pivotally connected to the container body 110. For example, the door 130 can be pivotally connected to the upright 113. In this way, the door 130 can rotate between a first open position and a first closed position. When the door 130 is in the first open position, the top opening 117 is open, and goods can be loaded into the container body 110 through the top opening 117.

[0028] When the upper door 130 is in the first closed position, the upper door 130 closes the upper opening 117. This protects the goods inside the container 110.

[0029] Please continue to refer to this. Figures 1 to 5 The container also includes a door stop 140. Along the height of the container body 110, the door stop 140 is smaller than the top opening 117. The door stop 140 is used to connect to the container body 110. The door stop 140 has a blocking position and an open position.

[0030] With the upper door 130 in the closed position and the door stop 140 in the blocking position, the door stop 140 is located inside the upper door 130. Therefore, the structure of the housing 110 is simple. Furthermore, opening the upper door 130 first and then operating the door stop 140 makes operation simple.

[0031] Optionally, along the height direction of the housing 110, the height dimension of the door stop 140 ranges from 2 / 5 to 3 / 5 of the height dimension of the upper opening 117. The height dimension of the upper part of the upper opening 117 is approximately equal to the height dimension of the lower part of the upper opening 117.

[0032] When the door stop 140 is in the blocking position, it connects to the container body 110. For example, the door stop 140 connects to the center beam 115 and the two uprights 113. In this case, the door stop 140 covers the lower part of the upper opening 117. The door stop 140 is located below the top beam 114. The door stop 140 and the top beam 114 are spaced apart. The portion of the upper opening 117 above the door stop 140 (the upper part of the upper opening 117) connects to the internal space of the container body 110. Goods can be loaded into the container body 110 through the upper part of the upper opening 117.

[0033] With the door stop 140 in the open position, the lower part of the upper opening 117 is open. The lower part of the upper opening 117 connects to the internal space of the container 110. At this time, goods can be loaded into the internal space of the lower part of the upper opening 117.

[0034] Thus, when the container is used to transport easily damaged agricultural products such as fruit, when it is necessary to load goods into the container body 110, the upper door 130 can be rotated to the first open position, and then the door stop 140 can be moved to the open position. At this time, goods can be loaded into the interior space of the container body 110 through the lower part of the upper opening 117. When the height of the goods piled up inside the container body 110 approaches the upper surface of the middle beam 115 of the upper opening 117, the door stop 140 can be positioned in the blocking position to cover the lower part of the upper opening 117. At this time, goods can be loaded into the container body 110 through the upper part of the upper opening 117. In this way, the height from which the goods entering the container body 110 fall inside the container body 110 is reduced, thereby reducing the possibility of damage to the goods during loading.

[0035] Optionally, such as Figure 1 Only Figure 3As shown, the container body 110 also includes a lower opening 118. The door frame 112 also includes a lower beam 116. For example, the lower beam 116 is the threshold of the end wall 111. The end of the lower beam 116 is connected to the bottom end of the upright 113. Thus, the middle beam 115, the two uprights 113, and the lower beam 116 form the lower opening 118. The lower opening 118 is separated from the upper opening 117. The lower opening 118 is located below the upper opening 117. The container also includes a lower door 150, which is rotatably connected to the container body 110. Thus, the lower door 150 can rotate between a second open position and a second closed position.

[0036] When the lower door 150 is in the second open position, the lower opening 118 opens. At this time, goods inside the container 110 can be unloaded through the lower opening 118. When the lower door 150 is in the second closed position, the lower door 150 closes the lower opening 118. This prevents goods inside the container 110 from falling out of the container 110.

[0037] The upper door 130 is used to fully open or close the upper opening 117, and the door stop 140 is used to cover the lower part of the upper opening 117 or to open the lower part of the upper opening 117. In this way, the height position for loading goods into the container 110 can be selected as needed, thereby minimizing damage to the goods. When unloading is required, the goods in the container 110 can be unloaded through the lower opening 118.

[0038] In this embodiment, the lower door 150 is in the second closed position, the door stop 140 is in the open position, and the upper door 130 is in the first open position. This allows goods to be loaded into the box 110 through the upper opening 117. In this case, the lower door 150 can prevent goods from leaking out. When the height of the goods piled up inside the box 110 is close to the upper surface of the middle beam 115 of the upper opening 117, the door stop 140 can be in the blocking position. This allows goods to be loaded into the box 110 through the upper part of the upper opening 117. In this case, the lower door 150 and the door stop 140 can prevent goods from leaking out.

[0039] Optionally, in the container body 110, one end wall 111 is provided with an upper opening 117. The other end wall 111 is provided with a container opening. The container also includes a door connected to the container body 110 for opening or closing the container opening. The container body 110 includes corner posts. In this case, the uprights 113 are corner posts. The top beam is the top beam of the container body.

[0040] like Figure 4As shown, the corner post includes an outer corner post 123 and an inner corner post 124. The outer corner post 123 is connected to the side wall. The outer corner post 123 forms the outer surface of the corner post. Along the length and width directions of the housing 110, the inner corner post 124 is located on the inner side of the outer corner post 123 near the center of the housing 110. The inner corner post 124 is connected to the outer corner post 123. The inner corner post has an inner end 122. Along the length direction of the housing 110, the inner end 122 is located at the end of the inner corner post 124 near the center of the housing 110.

[0041] When the door stop 140 is in the blocking position, it is located outside the inner end 122 along the length of the housing 110. This reduces the volume of the internal space occupied by the door stop 140 in the blocking position.

[0042] Furthermore, the outer corner post 123 includes a first outer corner post 125 and a second outer corner post 126. The first outer corner post 125 is connected to the side wall. Along the width direction of the housing 110, the second outer corner post 126 is located inside the first outer corner post 125 near the center of the housing. The second outer corner post 126 is connected to the first outer corner post 125.

[0043] The inner corner post 124 is a flat plate structure. The plane containing the inner corner post 124 is perpendicular to the length direction of the box body 110. Along the length direction of the box body 110, the inner corner post 124 is located on the inner side of the second outer corner post 126 near the box body 110 and is connected to the second outer corner post 126. The end of the inner corner post 124, along the length direction of the box body 110, away from the center of the box body 110, extends to the first outer corner post 125 and is connected to the first outer corner post 125. Along the length direction of the box body 110, the inner stop portion 119 (described later) is located on the side of the second outer corner post 126 near the center of the box body and is connected to the second outer corner post 126. Therefore, the corner posts have high strength.

[0044] It is understood that, in embodiments not shown, the upper and lower openings can be located on the side walls. In this case, the box body also has columns on the side walls. The length direction of the columns is parallel to the vertical direction. The columns and the ends of the box body are spaced apart along the length direction of the box body. The door frame includes two columns. The top beam is a top side beam. The bottom beam is a bottom side beam.

[0045] Optionally, such as Figure 3As shown, the door frame 112 also includes an inner baffle 119. The inner baffle 119 and the upright are two different parts. The inner baffle 119 has a columnar structure. The length direction of the inner baffle 119 and the length direction of the upright 113 are both parallel to the height direction of the housing 110. The lower end of the inner baffle 119 is connected to the middle beam 115. Along the length direction of the top beam 114, the inner baffle 119 is located on the inner side of the upright 113 near the center of the upper opening 117. The inner baffle 119 is connected to the upright 113. The upper end of the inner baffle 119 is spaced apart from the top beam 114. Thus, the top beam 114, the upright 113, the inner baffle 119, and the middle beam 115 form the upper opening 117. The inner baffle 119 is located at the lower part of the upper opening 117. The upper part of the upper opening 117 is located above the inner baffle 119.

[0046] When the door stop 140 is in the blocking position, the door stop 140 connects to the inner stop 119. This results in a strong connection between the door stop 140 and the housing 110. Furthermore, the inner stop 119 increases the strength of the door frame 112.

[0047] Optionally, such as Figure 3 As shown, the door stop 140 is pivotally connected to the inner stop 119, and thus connected to the column 113 via the inner stop 119. This prevents the door stop 140 from flipping downwards and hitting workers when it is opened.

[0048] Optionally, the upper door 130 includes two upper door crossbeams and two upper door vertical beams 131. When the upper door 130 is in the first closed position, the length direction of the upper door crossbeams is parallel to the width direction of the housing 110. The length direction of the upper door vertical beams 131 is parallel to the height direction of the housing 110. The two upper door crossbeams include a first upper door crossbeam located at the top of the upper door 130 and a second upper door crossbeam located at the bottom of the upper door 130. Along the length direction of the upper door crossbeams, the two upper door vertical beams 131 are located at opposite ends of the upper door 130. The two upper door crossbeams and the two upper door vertical beams 131 are connected to form a generally rectangular upper door frame 135 that is circumferentially closed.

[0049] The upper door 130 also includes an upper door panel 134. The upper door panel 134 is connected to the upper door frame 135 to cover the area enclosed by the upper door frame 135.

[0050] The upper door 130 also includes an upper door center beam 132. The length direction of the upper door center beam 132 is parallel to the upper door crossbeam. The upper door center beam 132 is located between the two upper door crossbeams. Along the height direction of the housing 110, the upper door center beam 132 and the two upper door crossbeams are spaced apart. The upper door panel 134 includes a first upper door panel and a second upper door panel. The first upper door panel is attached to the inner side of the upper door center beam 132 and the first upper door crossbeam. The second upper door panel is attached to the outer side of the upper door center beam 132 and the second upper door crossbeam. In this way, the second upper door panel, the upper door center beam 132 and the second upper door crossbeam form a mounting groove 133 with an opening facing the interior of the housing 110 (when the upper door 130 is in the first closed position). As a result, the upper door 130 has high strength.

[0051] It should be noted that the inner and outer sides of the components in this document refer to their positions when the upper door 130 is in the first closed position, the door stop 140 is in the blocking position, and the lower door 150 is in the second closed position. For example, the inner side of component H along the length of housing 110 refers to the side of component H near the center of housing 110 along the length of housing 110. The outer side of component H along the length of housing 110 refers to the side of component H away from the center of housing 110 along the length of housing 110.

[0052] Optionally, the upper door panel 134 is a flat plate or a corrugated plate. When the door stop 140 is in the blocking position, and in the second case where the upper door 130 is in the first closed position, the door stop 140 and the upper door 130 do not interfere with each other. Therefore, the structure of the upper door panel 134 is simple.

[0053] Optionally, such as Figure 2 and Figure 3 As shown, the doorstop 140 includes two doorstop horizontal beams and two doorstop vertical beams. When the doorstop 140 is in the blocking position, the length direction of the doorstop horizontal beams is parallel to the width direction of the housing 110. The length direction of the doorstop vertical beams is parallel to the height direction of the housing 110. The two doorstop horizontal beams include a first doorstop horizontal beam located at the top of the doorstop 140 and a second doorstop horizontal beam located at the bottom of the doorstop 140. Along the length direction of the doorstop horizontal beams, the two doorstop vertical beams are located at opposite ends of the doorstop 140. The two doorstop horizontal beams and the two doorstop vertical beams are connected to form a circumferentially closed, generally rectangular doorstop frame 141.

[0054] The door stop 140 also includes a door stop panel 142. The door stop panel 142 is connected to the door stop frame 141 to cover the area enclosed by the door stop frame 141. The door stop panel 142 is fitted to the outer or inner side of the door stop frame 141. As a result, the door stop 140 has high strength.

[0055] Alternatively, the door stop 142 can be a flat plate. Thus, the structure of the door stop 142 is simple.

[0056] Optionally, such as Figure 2 , Figure 4 and Figure 6 As shown, the height of the second upper door panel corresponds to the height of the door stop 140. That is, the height of the second upper door panel and the height of the door stop 140 are approximately the same. When the upper door 130 is in the closed position and the door stop 140 is in the blocking position, at least a portion of the door stop 140 extends into the mounting groove 133 of the upper door 130. Thus, when the upper door 130 is in the closed position and the door stop 140 is in the blocking position, there is a gap between the structures of the door stop 140 and the upper door 130 that form the mounting groove 133, to prevent the door stop 140 from contacting the upper door 130 when it deforms, thereby preventing the upper door 130 from rotating to the first closed position. Furthermore, the volume of the internal space of the housing 110 occupied by the door stop 140 in the blocking position can be reduced.

[0057] Alternatively, please continue to refer to Figure 6 The inner stop 119 connects to the second outer corner post 126, thereby forming a stop post groove 121. When the upper door 130 is in the first closed position, an upper door vertical beam 131 is located within the stop post groove 121. This reduces the thickness of the upper door 130 and the door stop 140, thereby reducing the volume of the internal space of the housing 110 occupied by the door stop 140 in the blocking position. When the upper door 130 is in the first closed position, the thickness direction of the upper door 130 is parallel to the length direction of the housing 110. When the door stop 140 is in the blocking position, the thickness direction of the door stop 140 is parallel to the length direction of the housing 110.

[0058] Optionally, both the door stop 140 and the upper door 130 are pivotally connected to the same column 113. Thus, an operator can rotate the door stop 140 and the upper door 130 from one side of the housing 110, facilitating the operation of rotating the door stop 140 and the upper door 130.

[0059] Optionally, the upper door 130 is a single door. Thus, the upper opening 117 can be closed by using the upper door 130, making the operation of the upper door 130 simple.

[0060] It is understood that, in the embodiment not shown, the upper door is a double-door structure. As a result, the weight of a single upper door is small.

[0061] Optionally, such as Figure 3 As shown, a protruding limiting plate 144 is provided at the end of the door stop 140 along its width direction. When the door stop 140 is in the blocking position, the limiting plate 144 is located on the outer side of the inner stop portion 119 away from the center of the housing 110 along the length direction of the housing 110. In this way, the inner stop portion 119 can block the limiting plate 144, thereby preventing the door stop 140 from flipping towards the center of the housing 110 along the length direction of the housing 110.

[0062] Optionally, please return Figure 1 The container includes an outer door latch 160 and an outer door socket 161. The outer door latch 160 is movably connected along its axial direction to the end of the upper door 130 opposite to its pivot position. The axial direction of the outer door latch 160 is parallel to the length direction of the upper door crossbeam or the height direction of the container body 110. The outer door socket 161 is connected to the door frame 112 (e.g., to the upright 113). When the upper door 130 is in the first closed position, the outer door latch 160 can be inserted into the outer door socket 161 to lock the upper door 130 in the first closed position. At this time, if it is necessary to rotate the upper door 130 to the first open position, the outer door latch 160 can be moved away from the socket.

[0063] The container includes an outer door lever 162. The outer door lever 162 is rotatably connected to the container body 110 (e.g., to the door frame 112). An outwardly protruding upper door locking portion 163 is provided on the outer peripheral surface of the outer door lever 162. The upper door locking portion 163 is a plate. One end of the upper door locking portion 163 is welded to the outer door lever 162. The upper door locking portion 163 is used to press against the end of the upper door 130 in its first closed position, opposite to the pivot position of the upper door 130. Specifically, when the upper door 130 is in the first closed position, the outer door lever 162 can be rotated to flip the upper door locking portion 163, causing the upper door locking portion 163 to press against the outer side of the upper door 130, thereby locking the upper door 130 in the first closed position.

[0064] Furthermore, the outer door pressure rod 162 extends axially along the height direction of the housing 110. The outer door pressure rod 162 is pivotally connected to the column 113.

[0065] Optionally, the container also includes a locking rod assembly 166. The locking rod assembly 166 can be an existing container locking rod assembly. The locking rod assembly 166 includes a locking rod, a locking seat, and a locking head. A locking head is provided at the end of the locking rod. The locking seat is connected to the door frame 112, and the locking rod is rotatably connected to the upper door 130. Thus, when the upper door 130 is in the first closed position, the locking rod assembly 166 can lock the upper door 130 in the first closed position. In this way, the locking rod assembly 166, the outer door latch 160, and the outer door pressure bar 162 work together to more securely lock the upper door 130 in the first closed position.

[0066] Furthermore, the length direction of the locking rod of the locking rod assembly 166 is parallel to the height direction of the housing 110. This allows the upper door 130 to be more securely locked in the first closed position.

[0067] Alternatively, please refer to Figure 1 and Figure 3The container includes a lower door lever 167. The lower door lever 167 is rotatably connected to the container body 110. An outwardly protruding lower door locking portion 168 is provided on the outer peripheral surface of the lower door lever 167. The lower door locking portion 168 is a plate. One end of the lower door locking portion 168 is welded to the lower door lever 167. The lower door locking portion 168 is used to press against the lower door 150 in its second closed position and the pivot position opposite to the lower door 150.

[0068] Specifically, when the lower door 150 is in the second closed position, the lower door lever 167 can be rotated to flip the lower door locking part 168 so that the lower door locking part 168 presses against the outer side of the lower door 150 along the length direction of the housing 110, thereby locking the lower door 150 in the second closed position.

[0069] Furthermore, such as Figure 1 and Figure 3 As shown, the lower door 150 is pivotally connected to the upper edge of the lower opening 118 (i.e., the middle beam 115). Thus, the lower door 150 has an upward-opening structure. This facilitates the unloading of bulk goods from the container 110.

[0070] like Figure 1 and Figure 3 As shown, the axial direction of the lower door pressure rod 167 is parallel to the width direction of the housing 110. This allows the lower door 150 to be locked more stably in the second closed position.

[0071] Optionally, along the height direction of the box 110, the size of the upper opening 117 is between 2 and 2.5 times the size of the lower opening 118. This minimizes damage to perishable agricultural products when they are placed into the box 110.

[0072] Optionally, such as Figure 3 As shown, the container includes a door stop rod 164 and a door stop socket 165. The door stop rod 164 is movably connected along its axial direction to one end of a door stop 140 opposite to its pivot position. The door stop socket 165 is connected to the container body 110. When the door stop 140 is in the blocking position, the door stop rod 164 can be inserted into the door stop socket 165.

[0073] Doorstop rod 164 is movably connected to doorstop 140 along its axial direction. The axial direction of doorstop rod 164 is parallel to the length direction of doorstop beam or the height direction of housing 110. Doorstop socket 165 is connected to door frame 112 (e.g., to inner stop 119). When doorstop 140 is in the blocking position, doorstop rod 164 can be inserted into doorstop socket 165 to lock doorstop 140 in the blocking position. At this time, if it is necessary to move doorstop 140, doorstop rod 164 can be moved away from doorstop socket 165.

[0074] Optionally, a loading opening is provided on the top wall. The container 110 also includes a loading door. The loading door is pivotally connected to the top wall to open or close the loading opening. Thus, when goods are loaded into the container 110 through the upper part of the upper opening 117, when the goods accumulate to the upper surface of the door stop 140, the upper door 130 can be rotated to the first closed position. At this time, the loading door can be rotated to open the loading opening, and goods can then be continued to be loaded into the container 110 through the loading opening.

[0075] Optionally, the container also includes seals. Seals are provided for the upper door 130, lower door 150, loading door, and container door. When the upper door 130 is in the first closed position, the seal on the upper door 130 is located between the upper door 130 and the container body 110 to seal the gap between them. When the lower door 150 is in the second closed position, the seal on the lower door 150 is located between the lower door 150 and the container body 110 to seal the gap between them. When the container door is closed, the seal on the container door is located between the container door and the container body 110 to seal the gap between them. When the loading door is closed, the seal on the loading door is located between the loading door and the container body 110 to seal the gap between them. Therefore, the container has strong sealing performance.

[0076] Optionally, the door stop 140 rotates by an angle α between the blocking position and the open position. α > 90°. This facilitates loading.

[0077] Furthermore, 140°≤α≤150°. This makes loading more convenient.

[0078] Optionally, the length dimension of the door stop 140 along its length direction is A. The maximum internal dimension of the upper opening 117 along the width direction of the top beam 114 is B. A > 0.7 B. This facilitates loading.

[0079] Furthermore, A > 0.8 B. A > 1400mm. This makes loading more convenient.

[0080] It should be noted that when the door stop 140 is in the blocking position, the length direction of the door stop 140 is parallel to the width direction of the box body 110.

[0081] Optionally, the door 130 rotates by an angle β between the first open position and the first closed position. β > 180°. This facilitates the operation of the door stop 140.

[0082] Second Implementation Method like Figure 7 and Figure 8As shown, in the second embodiment, the door stop 240 further includes a door stop reinforcing beam 243. The length direction of the door stop reinforcing beam 243 is parallel to the door stop vertical beam. The door stop reinforcing beam 243 is located within the area enclosed by the door stop frame. The end of the door stop reinforcing beam 243 is connected to the door stop horizontal beam. Therefore, the door stop has high strength.

[0083] It is understood that, in an embodiment not shown, the length direction of the door stop reinforcing beam is parallel to the door stop crossbeam.

[0084] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described in detail here.

[0085] Third Implementation Method In the third embodiment, such as Figure 9 As shown, the door stop reinforcement beam 243 can be omitted. In this case, the door stop 343 is a corrugated plate.

[0086] The other settings of the third embodiment are largely the same as those of the second embodiment, and will not be described in detail here.

[0087] Fourth Implementation Method like Figure 10 and Figure 11 As shown, in the fourth embodiment, the door stop 440 is pivotally connected to the center beam 415. This allows the door stop 440, when in the blocking position, to be flipped downwards to the open position. This facilitates the operation of rotating the door stop 440 from the blocking position to the open position.

[0088] Optionally, α is greater than 90°. This facilitates loading.

[0089] The other settings of the fourth embodiment are largely the same as those of the first embodiment, and will not be described in detail here.

[0090] Fifth Implementation Method like Figure 12 As shown, in the fifth embodiment, the housing may not have an inner stop. In this case, when the door stop 540 is in the blocking position, the door stop 540 is connected to the second outer corner post of the upright 513. When the door stop 540 is in the blocking position and the upper door is in the first closed position, the door stop 540 is located outside the upper door. The door stop 540 does not extend into the upper door.

[0091] Optionally, α is greater than 170°. This facilitates loading.

[0092] The other settings of the fifth embodiment are largely the same as those of the fourth embodiment, and will not be described in detail here.

[0093] Sixth Implementation Method like Figure 13 As shown, in the sixth embodiment, the door stop 640 is detachably connected to the housing. Therefore, the structure of the housing is simple.

[0094] The other settings of the sixth embodiment are largely the same as those of the first embodiment, and will not be described in detail here.

[0095] Seventh Implementation Method like Figures 14 to 16 As shown, in the seventh embodiment, the door stop 740 is movably connected to the housing 110 along its height direction. Thus, moving the door stop 740 up and down allows it to move between a blocking position and an open position.

[0096] Optionally, such as Figure 16 As shown, the column is equipped with a guide rail 760 extending along the height direction of the housing 110. Along the width direction of the door frame (i.e., the length direction of the top beam), the end of the door stop 740 is provided with an extending guide portion 745. The guide portion 745 extends into the guide rail 760. Thus, during the up-and-down movement of the door stop 740, the guide rail 760 and the guide portion 745 cooperate to guide the movement of the door stop 740. Therefore, the up-and-down movement of the door stop 740 is smooth.

[0097] Furthermore, the container also includes guide wheels. These guide wheels are rotatably mounted within the guide section and are located within the guide rails. This allows for smooth up-and-down movement of the door stop.

[0098] It is understood that, in embodiments not shown, the door stop may not have a guide portion. In this case, the end of the door stop extends into the guide rail along the width direction of the door frame (i.e., the length direction of the top beam). Thus, during the up-and-down movement of the door stop, the end of the door stop along the width direction of the door frame and the guide portion cooperate to guide the movement of the door stop.

[0099] like Figure 14 As shown, the container also includes a return spring 761. The return spring 761 is connected to the door stop 740 and the door frame to apply a force to the door stop 740, causing it to move towards a blocked position or an open position. In this embodiment, the return spring 761 applies a force to the door stop 740 that causes it to move towards the open position. This allows the door stop 740 to automatically return to the open position.

[0100] Furthermore, the return spring 761 is a cylindrical spring. The upper end of the return spring 761 is connected to the top beam. The lower end of the return spring 761 is connected to the door stop 740. The return spring 761 is in a stretched state to apply an upward force to the door stop 740. Thus, the container structure is simple.

[0101] In an embodiment not shown, the return spring is located inside the guide rail. This avoids the return spring occupying space at the top opening.

[0102] The other settings of the seventh embodiment are largely the same as those of the first embodiment, and will not be described again here.

[0103] Eighth Implementation Method like Figure 17 As shown, in the eighth embodiment, the return spring 860 is a torsion spring. The container also includes a mounting shaft 861 and a flexible connector 862. The flexible connector 862 can be a rope or a wire rope. One end of the flexible connector 862 is connected to the mounting shaft 861. The mounting shaft 861 is rotatably connected to the door frame. The axial direction of the mounting shaft 861 is parallel to the length direction of the top beam. The mounting shaft 861 is located below the top beam. The other end of the flexible connector 862 is connected to the door stop. The torsion spring is sleeved on the mounting shaft 861. The legs of the torsion spring abut against the container body to apply a force to the mounting shaft 861 to rotate it.

[0104] The flexible connector 862 is wound around the mounting shaft 861. When the door stop 840 moves downward, the door stop 840 pulls down the flexible connector 862, causing the mounting shaft 861 to rotate. When the door stop 840 leaves the blocking position, the force of the torsion spring on the mounting shaft 861 causes the mounting shaft 861 to wrap around the flexible connector 862, thereby pulling the door stop 840 upward.

[0105] In an embodiment not shown, the flexible connector is located inside the guide rail. This avoids the flexible connector occupying space at the top opening.

[0106] The other settings of the eighth embodiment are largely the same as those of the seventh embodiment, and will not be described again here.

[0107] Ninth Implementation Method In the ninth embodiment, such as Figure 18 As shown, the inner corner post 924 extends along the width of the housing, protruding beyond the second outer corner post 926 to form an inner stop. In other words, the inner stop is part of the inner corner post 924. When the door stop 940 is in the blocking position, the door stop 940 is connected to the inner corner post 924. Therefore, the number of parts in the housing is reduced, making it easier to manufacture.

[0108] The other configurations of the ninth embodiment are largely the same as those of the first embodiment, such as the structure of the first and second corner pillars. These will not be described in detail here.
