Description

Technical Field

[0001] The present application relates to the technical field of containers, and in particular to a container. Background Art

[0002] In the field of container transportation, tarpaulin open-top containers are widely used in transporting bulk cargo, granular cargo and other special cargoes due to their unique loading and unloading advantages.

[0003] Existing tarpaulin-covered open-top containers typically use complex sealing structures to prevent rainwater and other substances from seeping into the container from the top. For example, the front top sealing structure is a combination of a drain pan, a sealing strip, and a rain shield. The tarpaulin is connected to the top bow, and when the movable end of the tarpaulin moves to the front, it passes over the sealing strip and moves under the rain shield. This structure requires sealing strips and rain shields, which affect the length of the top opening in the container. The rain shield requires more steel, sealing rubber, fasteners, and more production steps and man-hours. It requires maintenance and is inconvenient to clean. The strips are prone to aging after long-term weathering and need to be replaced and maintained. There is also a risk of them falling into the cargo.

[0004] Therefore, a container is needed to at least partially solve the above problems. Summary of the Invention

[0172] In an optional embodiment, the shielding assembly 113 further has a fixed end 114, and the free end 115 is movable relative to the fixed end 114 along the length direction D1 of the container 100, wherein the fixed end 114 is arranged at the front end 103 of the box body 101, and in the retracted state, the free end 115 is close to the front end 103 to open the opening 109, and in the extended state, the free end 115 is located at the rear end 102 to shield the opening 109.

[0173] In an embodiment not shown, for example, in a 40-foot container, two shielding assemblies may be provided, with the fixed ends of the two shielding assemblies positioned in the middle of the container, and the free ends moving toward each other. Alternatively, a single fixed end may be provided, but the fixed end may be fixedly connected to the center of the container, and the free ends may move toward each other. In another alternative embodiment, a fixed end may not be provided, and both ends may be configured as free ends, so that the ends of the shielding assemblies can move toward the front and rear ends, respectively.

[0174] Optionally, the free end of the shielding assembly may also be designed to move along the width direction D2 of the container. In other words, the shielding assembly may be constructed as a side-sliding structure.

[0175] In this embodiment, the shielding assembly 113 includes a plurality of top bows 116, a tarpaulin assembly 117 and a movable portion 124. The plurality of top bows 116 are movably arranged on the top of the box body 101 along the length direction D1, for example, they can be arranged on the top side beam 105. The movable portion 124 is arranged at both ends of the top bow 116 along the width direction D2 of the container 100. Preferably, the movable portion 124 can be arranged only on the top bow 116 forming the free end 115. A guide structure is provided on the top side beam 105, for example, the two top side beams 105 are constructed as an L-shaped structure with openings away from each other. The movable portion 124 is connected in cooperation with the guide structure so that the movable portion 124 can move along the guide structure. The movable portion 124 forms a similar interlocking structure with the L-shaped top side beam 105 guide structure.

[0176] The tarpaulin assembly 117 covers the top bows 116. More specifically, one end of the tarpaulin assembly 117 is fixedly connected to the front end 103 of the box body 101, forming the aforementioned fixed end 114. The remaining portion of the tarpaulin assembly 117 covers the plurality of top bows 116, thereby being able to move through the top bows 116 to cover the opening 109. The top bow 116 farthest from the fixed end 114 forms the aforementioned free end 115.

[0177] refer to Figure 3 The container 100 further includes a traction member 135, a transmission assembly 136, and a drive chain 141. The traction member 135 is connected to the plurality of top bows 116, and movement of the traction member 135 can drive movement of the top bows 116. The traction member 135 can be configured as a steel wire rope, for example. The transmission assembly 136 is connected to the traction member 135 and includes a drive shaft 137. The drive shaft 137 extends along the width direction D2 of the sliding top container 100. The drive shaft 137 is mounted on the top side beam 105 via a bearing assembly 138. A pulley 139 and a sprocket 140 are mounted on the drive shaft 137. The traction member 135 is wound around the pulley 139.

[0178] Drive chain 141 is connected to transmission assembly 136 and includes a plurality of interlocking chain links 141A. Drive chain 141 is wound around sprocket 140 and is configured to move traction member 135 in response to a person's operation. Specifically, when a person pulls drive chain 141, it rotates sprocket 140, which in turn rotates drive shaft 137, which in turn rotates pulley 139, thereby tightening or releasing traction member 135.

[0179] In a preferred embodiment, reference Figure 10 and Figure 11 The tarpaulin assembly 117 includes a paving portion 118, a first water curtain 119 and a second water curtain 120, and the paving portion 118 covers the top bow 116. The first water curtain 119 and the second water curtain 120 are connected to the paving portion 118. Among them, the first water curtain 119 is located at the free end 115, and the second water curtain 120 is away from the free end 115 relative to the first water curtain 119. In other words, the second water curtain 120 is located between the free end 115 and the fixed end 114, and is arranged close to the free end 115. In addition, the first water curtain 119 and the second water curtain 120 both extend downward. In other words, the first water curtain 119 and the second water curtain 120 are both arranged to droop.

[0180] refer to Figure 10The container 100 also includes a drainage assembly 125, which includes a drainage structure and a sealing portion 128. The drainage structure is connected to the box body 101 and includes a drainage portion 126 and a water retaining portion 127. The drainage portion 126 is connected to the rear end 102 of the box body 101 and extends toward the interior of the box body 101, preferably extending obliquely upward. The water retaining portion 127 is connected to the drainage portion 126 and extends along the vertical direction D3 or extends obliquely upward. The sealing portion 128 is connected to the drainage structure, specifically to the water retaining portion 127. In an optional embodiment, the sealing portion 128 is connected to the side of the water retaining portion 127 facing the rear end 102. In the retracted state, the top of the drainage assembly 125 is open. In the extended state, the first water retaining curtain 119 is located on the outside of the sealing portion 128 relative to the middle of the box body 101. For example, the first water retaining curtain 119 can be located between the sealing portion 128 and the rear end 102, and the second water retaining curtain 120 abuts against the top surface of the sealing portion 128. In other words, in the extended state, the first water curtain 119 passes over the sealing portion 128. Preferably, the first water curtain 119 can partially or completely cover the drain assembly 125 in the height direction, thereby achieving a waterproof sealing effect.

[0181] According to the container 100 of the present application, a labyrinth seal is formed by the first water retaining curtain 119 and the second water retaining curtain 120 and the top of the drain assembly 125 to prevent rainwater from splashing into the box through the gap between the tarpaulin and the drain assembly 125, thereby enhancing the sealing performance without using sealing strips; and compared with the top sealing structure of the traditional sliding roof, the top rain shield and sealing strips are removed, the structure is simpler, and the subsequent maintenance and cleaning are more convenient, saving steel, rubber blocks and connecting parts, and also avoiding the risk of powder particles of the sealing rubber blocks falling into the cargo box.

[0182] The sealing portion 128 includes a transverse plate 131, which is connected to the drainage structure. Preferably, in the extended state, the second water curtain 120 is connected to the middle of the upper surface of the transverse plate 131. In other words, the second water curtain 120 is not tangential to the edge of the transverse plate 131. This approach has better sealing performance. In the case where the second water curtain 120 is in tangential contact with the edge of the transverse plate 131, as shown in FIG. Figure 15B As shown, there is a relatively higher probability of water leakage at this time.

[0183] refer to Figure 15A In order to achieve the connection between the second water curtain 120 and the cross plate 131, the length of the second water curtain 120 needs to be greater than the distance between the paving part 118 and the cross plate 131. In other words, the length of the second water curtain 120 is greater than the height difference between the top of the sealing part 128 and the top bow 116 forming the free end 115, thereby utilizing the flexible characteristics of the second water curtain 120 to achieve the overlap of the second water curtain 120 and the top surface of the sealing part 128, thereby achieving a double sealing effect.

[0184] In a preferred embodiment, reference Figure 15C The length of the second water curtain 120 cannot be too long, as this could easily cause it to become tangent to the edge of the transverse plate 131. The difference between the length of the second water curtain 120 and the distance between the paving portion 118 and the transverse plate 131 should be less than half the length of the transverse plate 131 along the length of the container. The length of the second water curtain 120 is related to the hardness of the tarpaulin. For softer tarpaulins, it can be slightly longer to prevent them from losing contact with the middle portion of the upper surface of the transverse plate 131.

[0185] As an implementation form, the sealing portion 128 specifically includes a first vertical plate 129, a second vertical plate 130 and the above-mentioned transverse plate 131. The first vertical plate 129 is connected to the water retaining portion 127, the second vertical plate 130 is spaced apart from the first vertical plate 129, and the transverse plate 131 is connected between the top ends of the first vertical plate 129 and the second vertical plate 130, so that the sealing portion 128 forms a downward opening. Thereby, the sealing portion 128 is roughly formed into a U-shape with an opening downward. Among them, the first vertical plate can be constructed as an integral structure with the water retaining portion 127, or the first vertical plate can be not provided, and the transverse plate 131 can be directly connected to the water retaining portion 127.

[0186] like Figure 12 As shown, the middle portion of the top bow 116 along the width direction D2 of the container 100 is higher than the two sides to form a first curved profile, and the middle portion of the drain assembly 125 along the width direction D2 of the container 100 is higher than the two sides to form a second curved profile, wherein the first curved profile is adapted to the shape of the second curved profile.

[0187] refer to Figure 13 The drain assembly 125 further includes an end sealing plate 132, which is disposed at the end of the sealing portion 128 along the width direction D2 and connected to the drain portion 126 and / or the water retaining portion 127 to prevent water from entering from the side. Furthermore, the end sealing plate 132 can prevent water that falls onto the drain portion 126 from splashing into the tank.

[0188] refer to Figure 14In the extended state, the projection of the end sealing plate 132 on a vertical plane perpendicular to the width direction D2 and the projection of the movable part 124 on a vertical plane perpendicular to the width direction D2 at least partially overlap. In other words, the two partially block each other in the width direction. There is a small gap between the outer side surface of the end sealing plate 132 along the width direction D2 and the movable part 124, for example, the gap between the two is less than 10 mm, thereby achieving a certain sealing effect. As a preferred embodiment, a sealing member 133 is provided on the outer side surface of the end sealing plate 132 along the width direction D2, thereby sealing the gap between the movable part 124 and the end sealing plate 132, further improving the waterproof performance. Among them, the sealing member 133 can be a flexible material such as a small tarpaulin piece or a rubber block. The drainage component 125 also includes a reinforcement part 134, which is located below the drainage part 126. One end of the reinforcement part 134 is connected to the box body 101, and the other end is connected to the drainage part 126.

[0189] like Figure 11 and Figure 12 As shown, the tarpaulin assembly 117 also includes a limiting cloth cover 123 and a sealing cloth cover 122. The limiting cloth cover 123 and the sealing cloth cover 122 are both connected to the paving portion 118. The limiting cloth cover 123 wraps each top bow 116 outside the sealing cloth cover 122, and the sealing cloth cover 122 wraps at least one top bow 116, for example, it needs to wrap at least the top bow 116 forming the free end 115. Optionally, the sealing cloth cover 122 includes two top bows 116 arranged in sequence from the free end 115 toward the fixed end 114, namely the top bow 116 forming the free end and another top bow 116 adjacent to it. Both can be used to drive the tarpaulin assembly 117 to extend or contract together when the top bow 116 moves, so that the two top bows 116 are superimposed to drive the tarpaulin assembly 117 to move back and forth, making the movement of the tarpaulin assembly 117 more stable. Furthermore, in the extended state, the sealing cloth cover 122 is at least partially located above the sealing portion 128, with the sealing cloth cover 122 abutting against the sealing portion 128 or the distance between the sealing cloth cover 122 and the sealing portion 128 being less than 10 mm. Thus, in addition to the two labyrinth seals formed by the first water retaining curtain 119 and the second water retaining curtain 120, the sealing cloth cover 122 forms an additional third seal, further improving watertightness.

[0190] refer to Figure 12 The tarpaulin assembly 117 further includes a third water curtain 121, which is located outside the movable portion 124 along the length direction D1. The third water curtain 121 extends downward, or in other words, is arranged to hang downward. Furthermore, the third water curtain 121 can also be located outside the movable portion 124 along the width direction. In other words, the third water curtain 121 can be configured to surround the movable portion 124 or the corner of the top bow 116.

[0191] Preferably, the third water curtain 121 and the first water curtain 119 are arranged to overlap at the movable portion 124, and the third water curtain 121 and the first water curtain 119 are fixed to the movable portion 124 by a fixing member. When the shielding assembly 113 is in the extended state, the drooping third water curtain 121 can prevent water from entering the gap between the movable portion 124 and the end sealing plate 132 bracket, thereby sealing the rear end 120 on both sides along the width direction D2. It is worth mentioning that due to the presence of guide structures on both sides of the box body 101, in order to avoid affecting the sliding of the movable portion 124, the length of the third water curtain 121 is preferably less than the length of the first water curtain 119. Specifically, the vertical length of the third water curtain 121 is less than or equal to the maximum distance between the upper surface of the guide structure and the upper surface of the movable portion 124. More specifically, the vertical length of the third water curtain 121 is less than or equal to the distance between the lower surface of the L-shaped structure formed by the top side beam 105 and the upper surface of the movable portion 124.

[0192] As an implementation, refer to Figures 5 to 9 The container 100 further includes a position limiting assembly 147 , which is disposed on the container body 101 and is used to limit the position of the drive chain 141 when no personnel are operating. The position limiting assembly 147 includes a position limiting bracket 148 and a position limiting device 157 .

[0193] A limiting bracket 148 is disposed on the housing 101 and defines a passage 154 that allows entry of the drive chain 141. A limiting device 157 is pivotally disposed on the limiting bracket 148 and can pivotally switch between a locked position and an open position. When the limiting device 157 is in the open position, the drive chain 141 can escape from or move within the passage 154. When the limiting device 157 is in the locked position, the limiting device 157 blocks the drive chain 141 from escaping from the passage 154 and prevents the drive chain 141 from moving within the passage 154. By disposing the limiting assembly 147 on the exterior of the housing 101 and locking the drive chain 141 with it, the limiting assembly 147 prevents the drive chain 141 from shaking up and down and causing the sprocket 140 to rotate. This prevents the shielding assembly 113 from automatically opening (extending) or closing (retracting). Furthermore, when the shielding assembly 113 is fully closed, the driving chain 141 can be locked into the limiting assembly 147 , thereby reducing the risk of the shielding assembly 113 being accidentally opened during transportation of the container 100 .

[0194] refer to Figure 7 and Figure 8As shown, the limiting bracket 148 includes a first bracket portion 150, a second bracket portion 152, a first bracket plate 149A, and a second bracket plate 149B. The first bracket portion 150 and the second bracket portion 152 are both located near the front end 103 of the housing 101, wherein the first bracket portion 150 is connected to the side wall of the housing 101 and the column 146 at the front end 103, and the second bracket portion 152 is connected to the column at the front end 103. It can be understood that the second bracket portion 152 is further away from the side wall of the housing 101 than the first bracket portion 150. The first bracket plate 149A is located at the end of the first bracket portion 150 away from the column 146, and the second bracket plate 149B is located at the end of the second bracket portion 152 away from the column 146. The limiting device 157 is pivotally mounted on the first bracket plate 149A.

[0195] The first bracket portion 150 and the second bracket portion 152 have portions that protrude toward each other, thereby forming a channel 154 between the first bracket portion 150 and the second bracket portion 152. Specifically, the first bracket portion 150 has a first bent portion 151, and the second bracket portion 152 has a second bent portion 153. The first bent portion 151 and the second bent portion 153 face each other, thereby forming the aforementioned channel 154 between the first bent portion 151 and the second bent portion 153.

[0196] The width of the channel 154, or the minimum distance between the first bracket portion 150 and the second bracket portion 152, is less than the width of the link 141A of the drive chain 141 but greater than the thickness of the link 141A. Therefore, when one link 141A is engaged in the channel 154 of the limiting bracket 148, the adjacent links 141A are in opposite directions, preventing the drive chain 141 from moving up or down, thereby limiting its height. When the limiting device 157 is in the locked position, it prevents the drive chain 141 from falling out of the channel 154.

[0197] The limiting assembly 147 further includes a first limiting pin 155 and a second limiting pin 156. The first limiting pin 155 is disposed on the first bracket plate 149A and is further away from the second bracket portion 152 than the first bracket portion 150. Preferably, the first limiting pin 155 is disposed on the side of the first bent portion 151 that is closer to the side wall of the box 101. The second limiting pin 156 is disposed on the second bracket plate 149B and is further away from the first bracket portion 150 than the second bracket portion 152. Preferably, the second limiting pin 156 is disposed on the side of the second bent portion 153 that is away from the side wall of the box 101.

[0198] The limiting device 157 is pivotally connected to the first limiting pin 155. When the limiting device 157 is in the open position, Figure 7As shown, the limiting device 157 is disengaged from the second limiting pin 156. When the limiting device 157 is in the locked position, as shown in FIG. Figure 8 As shown, the limiting device 157 is connected to the second limiting pin 156, and the second limiting pin 156 prevents the limiting device 157 from continuing to rotate downward.

[0199] The limiting device 157 includes a pivot portion 158, a blocking portion 159, and an operating portion 160. The pivot portion 158 is pivotally mounted on the first limiting pin 155, the blocking portion 159 is connected to the pivot portion 158, and the operating portion 160 is connected to the blocking portion 159. In other words, the blocking portion 159 is disposed between the pivot portion 158 and the operating portion 160.

[0200] The width of the shielding portion 159 is smaller than the widths of the pivoting portion 158 and the operating portion 160, thereby forming a groove between the pivoting portion 158 and the operating portion 160. When the limiting device 157 is in the locked position, the second limiting pin 156 is located in the groove and the shielding portion 159 overlaps the second limiting pin 156. In other words, when the limiting device 157 is in the locked position, the limiting device 157 and the second limiting pin 156 are engaged.

[0201] Preferably, the center of gravity 160A of the stopper 157 is located on the operating portion 160. This allows the stopper 157 to be in the open position, and the container wall prevents the stopper 157 from further rotating inward. The operating portion 160 abuts against the container wall 101, eliminating the need for manual maintenance of the open position. Furthermore, this design allows the operating portion 160 to automatically fall down after a person activates it, thereby locking it. For example, when the angle between the center of gravity 160A of the stopper 157 and the axis of rotation is no greater than 90 degrees, the stopper 157 can automatically close due to gravity, thus avoiding the risk of accidental opening during transportation of the container 100.

[0202] refer to Figure 4 , a support assembly 142 is also connected between the transmission shaft 137 and the top side beam 105. The support assembly 142 includes a support 143, a first support plate 144 and a second support plate 145. A through hole is provided on the support 143, and the transmission shaft 137 is arranged to pass through the through hole. The first support plate 144 is connected to the bottom of the support 143, and the second support plate 145 is connected to the top side beam 105 and abuts against the first support plate 144. In addition, the second support plate 145 is connected to the first support plate 144 by fasteners. Through the above-mentioned support assembly 142, the supporting strength of the transmission shaft 137 can be strengthened, and the bearing capacity of the bearing assembly 138 can be dispersed, which is conducive to ensuring the service life of the entire shielding assembly 113.

[0203] refer to Figures 16 to 20The container 100 further includes a ventilation mechanism 161, which includes a housing 162 and a closure 170. The housing 162 is mounted on the front wall panel 110 and covers the vent 111. The housing 162 protrudes from the front wall panel 110, and a ventilation hole 167 is provided on the bottom side of the housing 162. The closure 170 is located within the container body 101 and is movably connected to the portion of the front wall panel 110 located above the vent 111. When the container 100 is laid flat, the closure 170 closes the vent 111. When the rear end 102 of the container 100 is tilted forward, the bottom end of the closure 170 moves into the container body 101 and away from the vent 111.

[0204] According to the container 100 of the present application, when transporting goods, the box body 101 is in a horizontal state, and the closure member 170 can completely cover the vent 111, ensuring the sealing of the box body 101. When the container 100 is unloading goods, the box body 101 tilts toward the discharge end, and the closure member 170, under its own weight, partially detaches from the box wall. At this time, there is a larger ventilation area, achieving ventilation and pressure relief, making it easier to open the door, facilitating unloading, improving unloading efficiency, and saving time and labor costs.

[0205] In an optional embodiment, the closing member 170 is constructed as a rigid windshield, the upper end of the rigid windshield is hinged to the portion of the front wall panel 110 above the vent 111, and the lower end of the rigid windshield is suspended.

[0206] In another optional embodiment, if Figure 19 and Figure 20 As shown, the closure member 170 is constructed as an elastic windshield pad, the upper end of which is connected to the portion of the front wall panel 110 above the vent 111 via a fastener, and the lower end of which is suspended. In this embodiment, the fastener can be a rivet.

[0207] More specifically, refer to Figure 17 and Figure 18 The outer shell 162 includes a connecting portion 163, side panels 164, and a back panel 165. The connecting portion 163 is connected to the front wall panel 110. The side panels 164 are connected to the top of the connecting portion 163 and to both sides of the connecting portion 163 along the width direction D2 of the container 100, and the side panels 164 extend away from the front wall panel 110. The back panel 165 is connected to the side panels 164, and an air duct is formed between the back panel 165 and the front wall panel 110. The bottom of the air duct is configured as a ventilation hole 167. As an implementation form, the outer shell 162 also includes a ventilation plate 166. The ventilation plate 166 is connected to the bottom of the connecting portion 163 and the bottom of the back panel 165, and a plurality of ventilation holes 167 are formed on the ventilation plate 166.

[0208] As a preferred embodiment, the outer shell 162 further includes at least two baffles 168. These baffles 168 are connected between the side panels 164 along the width direction D2, and are spaced apart along the height direction of the container 100. One of two adjacent baffles 168 is connected to the back panel 165, while the other is spaced apart from the back panel 165 and abuts the front wall panel 110. This creates a labyrinthine air duct within the outer shell 162, preventing larger impurities such as dust, sand, and insects from entering the container 100. It also prevents rainwater backflow, provides flow regulation, and improves ventilation efficiency and effectiveness.

[0209] The surface of the back panel 165 facing the front wall panel 110 is further provided with reinforcement ribs 169 to strengthen the structural strength of the outer shell 162. The reinforcement ribs 169 extend along the length direction D1 of the container 100. Optionally, the reinforcement ribs 169 may also extend along the width direction D2 of the container 100.

[0210] refer to Figure 2 、 Figures 21 to 28 , the container 100 also includes a door end bottom locking mechanism 171. The door end bottom locking mechanism 171 includes a first locking rod 177, a second locking rod 181, a connecting rod assembly 185 and an operating assembly 193. Among them, the first locking rod 177 and the second locking rod 181 both extend along the width direction D2 of the container 100. The difference is that the first locking rod 177 is rotatably arranged on the inner side of the door sill beam 106A, and the second locking rod 181 is rotatably arranged on the outer side of the door sill beam 106A. Among them, the first locking rod 177 is located below the base frame, and it may not overlap with the door sill beam 106A. In other words, the inner side of the above-mentioned door sill beam 106A may refer to a certain distance from the door sill beam 106A. A lock hook 182 is provided on the second locking rod 181 (refer to Figure 2 、 Figure 22 and Figure 24 The flip door 112 is preferably provided with a lock seat 172 that cooperates with the lock hook 182. A connecting rod assembly 185 is connected between the second lock rod 181 and the first lock rod 177. The connecting rod assembly 185 is provided through the door sill beam 106A. The operating assembly 193 is connected to the first lock rod 177.

[0211] The first locking rod 177 is configured to rotate in response to the operation of the operating assembly 193, and the second locking rod 181 is configured to rotate in response to the rotation of the first locking rod 177 via the connecting rod assembly 185, so that the locking hook 182 switches between a locked state for locking the flip door 112 and an open state for opening the flip door 112. According to the container 100 of the present application, the second locking rod 181 is externally positioned to achieve locking, while the first locking rod 177 is internally positioned to achieve transmission control. This allows components that are more prone to wear and aging to be externally positioned, facilitating later repair and maintenance of components outside the container 100, thereby reducing maintenance costs.

[0212] refer to Figure 2 and Figure 22 The outer side of the door sill beam 106A is provided with a plurality of fixing sleeves 173. The inner diameter of the fixing sleeves 173 is adapted to the outer diameter of the second locking rod 181. The second locking rod 181 passes through the fixing sleeves 173 and is rotatable within the fixing sleeves 173. The fixing sleeves 173 are provided with oil holes 174 for injecting lubricating oil to maintain smooth door opening and closing operations.

[0213] Preferably, reference Figure 23 The second locking rod 181 includes a main body 183 and a contraction portion 184, with the contraction portion 184 located at both ends of the main body 183. The radial dimension of the contraction portion 184 is smaller than that of the main body 183. The fixing sleeve 173 includes an axial limiting sleeve, the inner diameter of which matches the outer diameter of the contraction portion 184. The contraction portion 184 extends into the axial limiting sleeve, so that the axial limiting sleeve axially limits the main body 183. In other words, the diameter of the ends of the second locking rod 181 is smaller than the diameter of the middle portion, and the axial limiting sleeves at both ends are mounted on both ends of the second locking rod 181, thereby preventing the second locking rod 181 from moving axially.

[0214] refer to Figure 25 The connecting rod assembly 185 includes a first connecting rod base 186, a second connecting rod base 189, and a connecting rod member 192. The first connecting rod base 186 is fixedly connected to the first locking rod 177, and the second connecting rod base 189 is fixedly connected to the second locking rod 181. The connecting rod member 192 is pivotally connected to the first connecting rod base 186, and the connecting rod member 192 is pivotally connected to the second connecting rod base 189.

[0215] In one implementation, first link seat 186 has a first axial hole 187 and a first pivot portion 188. First locking lever 177 is fixedly disposed in first axial hole 187, first pivot portion 188 is offset relative to first axial hole 187, and link member 192 is pivotally connected to first pivot portion 188. Second link seat 189 has a second axial hole 190 and a second pivot portion 191. Second locking lever 181 is fixedly disposed in second axial hole 190, second pivot portion 191 is offset relative to second axial hole 190, and link member 192 is pivotally connected to second pivot portion 191. Link member 192 is pivotally connected between first pivot portion 188 and second pivot portion 191.

[0216] refer to Figure 21 、 Figure 26 and Figure 27The operating assembly 193 is disposed on the side of the container 100 in the width direction D2. The first locking rod 177 extends through the bottom side beam 107 and is connected to the operating assembly 193. The first locking rod 177 is provided with a pair of limiting rings 178, with each pair of limiting rings 178 located on either side of the bottom side beam 107, thereby preventing the first locking rod 177 from moving along the width direction D2. The radial dimension of the end of the first locking rod 177 connected to the operating assembly 193 is smaller than the radial dimension of the main body of the first locking rod 177, thereby forming a limiting key 180 between the first locking rod 177 and the operating assembly 193. This secures the operating assembly 193 to the first locking rod 177, allowing operation of the operating assembly 193 to drive the first locking rod 177 to rotate. Furthermore, the limiting key 180 can limit the movement of the first locking rod 177 along the width direction D2 of the container 100.

[0217] like Figure 26 The container 100 further includes a threshold reinforcement plate 175 connected between the threshold beam 106A and the bottom crossbeam 108. A support seat 179 is provided on the threshold reinforcement plate 175, and a first locking rod 177 is disposed through the support seat 179. The support seat 179 supports and secures the first locking rod 177, preventing it from moving up and down.

[0218] refer to Figure 27 The operating assembly 193 specifically includes a mounting base 194, an operating handle 195, and a lever assembly 198. The mounting base 194 is mounted on the side of the container 100. One end of the operating handle 195 forms a pivot end 196, which is pivotally mounted on the mounting base 194. The other end of the operating handle 195 is operable by a human operator. The lever assembly 198 is fixedly connected to the first locking rod 177 and is also pivotally connected to the operating handle 195. It should be noted that the connection point between the lever assembly 198 and the operating handle 195 is offset relative to the pivot end 196 of the operating handle 195. More specifically, the pivot end 196 is pivotally mounted on the side of the container 100 via a first pin 197. The operating handle 195 is configured to rotate in response to an operator's movements. The lever assembly 198 is pivotally connected to the operating handle 195 via a second pin 199, which is located between the two ends of the operating handle 195.

[0219] This lever structure makes it easier for operators to operate the operating handle 195, saving labor. In addition, the combination of the lever structure and the double lock rods prevents the force of the operating handle 195 from being directly transmitted to the second lock rod 181, reducing the force on the second lock rod 181 and, to a certain extent, reducing wear.

[0220] refer to Figure 27 and Figure 28 The lever assembly 198 includes a rocker arm 200 and a handle link 201. The rocker arm 200 is fixedly connected to the first locking rod 177, and the handle link 201 is pivotally connected to the rocker arm 200. The handle link 201 is also pivotally connected to the operating handle 195. More specifically, the handle link 201 includes an adjustment rod 202, a first link 203, and a second link 204. One end of the first link 203 is pivotally connected to the rocker arm 200, and the other end is threadedly connected to the adjustment rod 202. One end of the second link 204 is pivotally connected to the operating handle 195, and the other end is threadedly connected to the adjustment rod 202. As a result, the distance between the first link 203 and the second link 204 can be adjusted by rotating the adjustment rod, thereby making the length of the handle link 201 adjustable, which is convenient for installation and debugging as well as adjusting the locking stroke of the lock hook 182.

[0221] As a preferred embodiment, the handle link 201 further includes a backstop 205 , which is provided on the second link 204 and adjacent to the adjustment rod 202 , so as to restrict the adjustment rod 202 after the length adjustment of the handle link 201 is completed, thereby preventing loosening.

[0222] In addition, the operating component 193 also includes a fixing device, which is arranged on the side of the container 100. When the operating handle 195 drives the first locking rod 177 and the second locking rod 181 to lock the upper flip door 112, the fixing device is connected to the mounting seat 194 to fix the operating handle 195.

[0223] As one embodiment, the fixing device includes a slot 207, a guide rod 208, and a locking ring 209. The slot 207 is fixedly mounted on the mounting base 194, forming an upward opening between the slot 207 and the mounting base 194. When the flip door 112 is locked, the operating handle 195 can enter the opening and overlap the bottom of the slot 207, thereby utilizing the slot 207 to limit and guide the operating handle 195. The guide rod 208 is fixedly connected to the slot 207 and the housing 101. It can be connected to a reinforced structure protruding from the side wall of the housing 101, or a separate fixing base can be provided on the side wall, and the guide rod 208 can be mounted on this fixing base.

[0224] The lock ring 209 is sleeved on the guide rod 208 and can slide along the guide rod 208. The end of the guide rod 208 close to the card slot 207 is lower than the end away from the card slot 207. When there is no external force, the lock ring 209 can automatically slide to the end close to the card slot 207 due to gravity.

[0225] During operation, in the initial state, that is, when the flip door 112 is in the open state, the lock ring 209 is located at the end near the slot 207 and hangs down, which does not affect the rotation of the operating handle 195. When the door needs to be locked, the operating handle 195 is rotated until it enters the slot 207, and the flip door 112 is locked. At this time, the lock ring 209 is moved to the end away from the slot 207, and after passing over the end of the operating handle 195, the lock ring 209 is lifted and then moved towards the slot 207. At the same time, the operating handle 195 is locked in the lock ring 209. The lock ring 209 can automatically slide along the guide rod 208 to the end near the slot 207 due to gravity, thereby locking the operating handle 195 and preventing it from moving upward, thereby ensuring that the flip door 112 is locked.

[0226] When opening the door, the lock ring 209 is moved to the end away from the slot 207 and released, or the end of the operating handle 195 is disengaged from the lock ring. The lock ring 209 is automatically in a drooping state and automatically slides toward the slot 207 to unlock the operating handle 195.

[0227] The fixing device utilizes the principle of gravity lock, is easy to operate, and ensures that when the flip door 112 and the operating handle 195 are in a locked state, the locking ring 209 does not separate from the handle.
