Preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and the like are used herein for purposes of illustration only and not limitation.

Herein, ordinal words such as "first" and "second" cited in the present application are merely identifiers and do not have any other meaning, such as a particular order or the like.

In order to provide a thorough understanding of the embodiments of the present application, a detailed structure will be presented in the following description. It will be apparent that embodiments of the present application may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.

The invention provides a side-opening container. The side-opening container may be a side-opening container. The side-opening door container includes a housing 110. The case 110 includes side walls, end walls, a chassis, and a top wall. The side walls, end walls, chassis and top wall are constructed in a generally rectangular parallelepiped configuration.

Referring to fig. 1 to 21, the underframe includes a bottom side sill 112 connected to the bottom side sill and a side sill. The length direction of the side sill 112 is parallel to the length direction of the bottom side sill. The top wall includes a top side rail and a side door header 113 connected to the top side rail. The longitudinal direction of the side door lintel 113 is parallel to the longitudinal direction of the top side beam. The side wall includes corner posts and side door posts. The upper ends of the side door posts are connected to the top wall. The lower end of the side door post is connected to the bottom wall. The side door posts are a plurality of. The plurality of side door posts are disposed at intervals along the length direction of the case 110. Adjacent side door posts, side door lintel 113 and side door sill 112 may enclose a side opening 111. The corner of the chassis is provided with a bottom corner piece.

It will be appreciated that in an embodiment not shown, the portion of the bottom side sill may constitute the side sill. Portions of the top side beams may constitute side door lintels.

The side-opening container also includes side-opening doors 120. The side opening door 120 is rotatably hinged to the pillar or side door post. In this way, the side door 120 can be rotated between an open position to open the side opening 111 and a closed position to close the side opening 111.

As shown in fig. 1, 16-21, the side-opening container further includes a locking bar assembly. The locking bar assembly also includes a locking bar 180 and a locking seat. Both the side door lintel 113 and the side door sill 112 are provided with lock seats. The lock lever 180 is rotatably provided to the side door 120. Locking bars 180 are provided with locking heads at both ends. With the side opening 120 in the closed position, the lock cylinder is docked to the lock base. At this time, the lock lever 180 is rotated to lock the lock head to the lock base, and thus the side door 120 is locked in the closed position.

Returning to fig. 1-5, the side-entry shipping container also includes a downwarping adjuster 130. The down-deflection regulating member 130 has a cam portion 131. The cam portion 131 has a top angle 132. The distance between the apex angle 132 of the cam portion 131 and the axis of the cam portion 131 is the apex angle distance. The apex angle distance is greater than the distance between the other positions of the cam portion 131 and the axis of the cam portion 131. In the radial direction of the downwarping adjuster 130, a line between the apex angle 132 of the cam portion 131 and the axis of the cam portion 131 is parallel to the cam height direction of the cam portion 131.

The axis AX1 of the cam portion 131 is the axis of the down-stroke adjuster 130. The down-link regulator 130 is rotatably connected to the side sill 112. In this way, the downwarp adjustment member 130 can be rotated to the adjustment position and the storage position.

As shown in fig. 1 to 5, when the side-opening container is placed on the support platform 100 (e.g., the ground), the bottom surface of the bottom corner fitting is supported on the support platform 100, so that the side-opening container is supported on the support platform 100. When the cam portion 131 adjusts the side sill 112 to deform (the downwarping adjuster 130 is located at the adjusting position), the apex angle 132 is directed to the ground, and the cam height direction is parallel to the vertical direction. When the cam portion 131 is not in operation, the cam is retracted (the down-deflection regulating member 130 is positioned at the retracted position), the apex angle 132 is directed to the end of the housing 110, and the height direction of the cam is horizontally parallel to the longitudinal direction of the housing 110.

As shown in fig. 2 and 4, in the case where the down-deflection regulating member 130 is located at the regulating position, the apex angle 132 of the cam portion 131 is located below the side sill 112. At this time, the top corner 132 may be abutted to the support platform 100, and the side sill 112 may be supported to the support platform 100 by the down-deflection adjusting member 130. In this way, the degree of downwarping (downward bending) of the side sill 112 can be reduced. In this way, the downwarping adjusting member 130 located at the adjusting position can be rotated according to specific situations, so as to reduce the downwarping degree of the side threshold 112, and avoid that the lock base and the lock head located at the side threshold 112 are staggered and cannot be abutted.

As shown in fig. 5, when the down-deflection regulating member 130 is located at the storage position, the top corner 132 is located within the outer contour of the case 110. Thereby facilitating transportation of the side-opening container.

In this embodiment, after the side door container is loaded with a heavy load, if the side door sill 112 deforms and is bent down, so that the lock rod assembly cannot lock the side door 120 in the closed position, the bending adjustment member 130 may be rotated, so that the top corner 132 of the bending adjustment member 130 abuts against the supporting platform 100, thereby reducing the degree of bending down the side door sill 112, and further enabling the lock head to be abutted to the lock seat located on the side door sill 112.

Similarly, when unloading a side-opening container containing heavy cargo, the side sill 112 is deflected downward by the downward pressure of the cargo within the container, and the subsequent sill lock 170 applies a downward directed force to the subsequent sill lock 181, which applies a downward directed force to the subsequent sill lock. Thus, the rotation of the lock lever 180 is difficult, and the operation of opening the side door 120 is difficult. At this time, the down-deflection adjusting member 130 is rotated to an adjusting position, so that the side door sill 112 is lifted up, so that the acting force between the door sill lock 170 and the door sill lock 181 and the acting force between the door lintel lock and the door lintel lock are reduced, and at this time, the rotation of the lock lever 180 is convenient, and the side door 120 can be easily opened.

Preferably, as shown in fig. 1 to 5, the axis of the downwarping adjuster 130 is parallel to the width direction of the case 110. Thus, the side door container has a simple structure.

With continued reference to fig. 1-5, the side-entry shipping container further includes a drive assembly 140. The driving assembly 140 is connected to the downwarping adjuster 130 for driving the downwarping adjuster 130 to rotate about the axis AX1 of the cam portion 131. Thereby facilitating control of rotation of the downwarping adjuster 130.

Further preferably, the side-opening container further comprises a first drive socket 143 and a second drive socket 144. The first driving seat 143 is connected to the side sill 112. The second drive seat 144 is connected to the side sill 112. One end of the driving assembly 140 is pivotally connected to the first driving socket 143. The other end of drive assembly 140 is pivotally connected to downwarp adjustment member 130. The down-deflection adjustment member 130 is rotatably coupled to the second drive socket 144. The length of the drive assembly 140 may vary. Thus, by varying the length of the driving assembly 140, the downwarping adjuster 130 can be rotated.

As shown in fig. 2 to 5, the driving assembly 140 includes a sleeve 141 and a screw 142. The sleeve 141 has an inner through hole. The two ends of the inner through hole are respectively provided with internal threads with opposite screwing directions. The screws 142 are two, one with left-handed external threads and the other with right-handed external threads. One end of a screw 142 extends from one end of the sleeve 141 into the inner through hole of the sleeve 141 and is screw-coupled to the sleeve 141. One end of the other screw 142 extends from the other end of the sleeve 141 into the inner through hole of the sleeve 141 and is screw-coupled to the sleeve 141.

One end of one screw 142 located outside the sleeve 141 is pivotally connected to a first drive socket 143. Thus, the sleeve 141 is pivotally connected to the first drive socket 143 by a screw 142. The other screw 142 is pivotally connected at one end to the downwarp adjustment member 130, which is located outside the sleeve 141. The sleeve 141 is rotatable about the axis of the sleeve 141. Thus, the screw 142 can be moved in the axial direction of the sleeve 141 with respect to the sleeve 141 by rotating the sleeve 141. Thus, the length of the driving assembly 140 can be adjusted by rotating the sleeve 141, so that the down-deflection adjusting member 130 can be rotated, and the operation is convenient. In addition, the driving assembly 140 has a simple structure.

Further preferably, the drive assembly 140 further comprises an operating member 145. The outer circumferential surface of the sleeve 141 is provided with a plurality of insertion holes. The plurality of receptacles are circumferentially spaced about the axis of the sleeve 141. The operating member 145 has a latch at an end thereof. The operating member 145 is detachably inserted into the insertion hole of the sleeve 141 by a latch. After the latch is inserted into the jack, the sleeve 141 can be driven to rotate by rotating the operating member 145. When the operating member 145 is about to interfere with the support platform or the case, the operating member 145 can be pulled out of the current receptacle and then the operating member 145 can be inserted into another receptacle to facilitate continued rotation.

It will be appreciated that in an embodiment not shown, the drive assembly may be a ratchet-type hand strap binder of the prior art. The wrench of the ratchet type wrench binder can rotate the sleeve, and the screws on two sides can stretch and retract relative to the sleeve so as to drive the down-deflection adjusting piece to rotate around the axis AX1 of the cam part.

It will be appreciated that in an embodiment not shown, the sleeve may also be provided with an operating plane. At this time, the socket can be rotated by a wrench and an operation plane of the related art.

The downwarp adjustment member 130 further includes a swing arm portion 133 connected to the cam portion 131. The swing arm portion 133 extends in the radial direction of the downwarp adjusting member 130. In this way, when the down-deflection adjusting member 130 rotates around the axis AX1 of the cam portion 131, the cam portion 131 and the swing arm portion 133 are driven to rotate around the axis AX1 of the cam portion 131. That is, the axis of the swing arm portion 133 is the axis AX1 of the cam portion 131. The length direction of the swing arm 133 is inclined to the cam height direction. The angle between the length direction of the swing arm 133 and the cam height direction is greater than 90 ° and less than 180 °. The swing arm 133 is pivotally connected to the screw 142. Thus, the swing arm portion 133 rotates with respect to the screw 142 about the swing axis AX2 of the screw 142. The oscillation axis AX2 of the screw 142 and the axis AX1 of the cam portion 131 are spaced apart. Thereby facilitating connection of the down-deflection adjustment member 130 and the drive assembly 140.

As shown in fig. 1, 6 to 11, the side door 120 has a door frame. The door frame comprises two door beams 121 and two door vertical beams 122. The two door beams 121 and the two door vertical beams 122 are connected end to constitute a substantially rectangular frame structure. The longitudinal direction of the door vertical beam 122 is parallel to the height direction of the case 110. When the side door 120 is in the closed position, the longitudinal direction of the door beam 121 is parallel to the longitudinal direction of the case 110. The upper and lower ends of the side opening door 120 are provided with door beams 121.

The side door 120 is provided with a side door lower latch 123. The side door lower lock 123 has a plate-like structure. The side door lower lock catch 123 is located below the door frame. The upper end of the side door lower latch 123 is connected to a door cross member 121 located at the lower end of the side door 120. The side door lower lock catch 123 has a side door lower lock catch hole 124. The axial direction of the side door lower lock catch hole 124 is parallel to the length direction of the door cross member 121.

The side-opening container also includes a lower shackle assembly. The lower striker assembly includes a side sill first seat 151 and a side door lower latch member 153. The side sill first seat 151 has a plate-like structure. The side sill first seat 151 is connected to the side sill 112. The side sill first seat 151 includes a side sill first seat aperture 152. The axial direction of the side sill first seating hole 152 is parallel to the length direction of the case 110.

The side door lower lock latch member 153 includes a body 154. The body 154 is a plate-like structure. The body 154 movably penetrates the side threshold first seat hole 152 along the length direction of the case 110. With the side door 120 in the closed position, the side door lower latch hole 124 is located at the side sill first seating hole 152 along the height direction of the case 110. At this time, the body 154 of the side door lower latch member 153 can extend into the side door lower latch hole 124. In this manner, having the side door 120 connected to the side sill 112 through the lower latch assembly may increase the strength of the side door container. Further, the degree of the side sill 112 being deflected can be reduced.

As shown in fig. 6 to 8, the side door lower lock latch member 153 further includes a stopper portion. The limiting part can be formed by bending a cylindrical section bar. The stopper includes a first arm 155 and a second arm 156. The axial direction of the first arm 155 is parallel to the width direction of the case 110. The axial direction of the second arm 156 is parallel to the length direction of the case 110. One end of the first arm 155 is connected to the body 154. The other end of the first arm 155 is connected to one end of the second arm 156. A spacing interval exists between the second arm 156 and the body 154 in the width direction of the case 110. The body 154 is disposed through the side sill first seat hole 152. At this time, the edge of the side sill first seat 151, which constitutes the side sill first seat hole 152, is located within the limit interval. Thus, a worker can grasp the second arm 156 to operate the side door lower lock latch member 153. The first arm 155 can cooperate with the side sill first seat 151 to prevent the body 154 from exiting the side sill first seat aperture 152.

With continued reference to fig. 6 to 8, the limiting portion further includes a third arm 157. The axial direction of the third arm 157 is parallel to the axial direction of the first arm 155.
