The adjustment structure 120 includes a lead screw 121 and a spherical portion. The spherical portion is disposed at the bottom end of the screw rod 121 and is located in the spherical hole 111 of the base 110. The connection of the base 110 and the lead screw 121 can be achieved by providing a spherical portion in the spherical hole 111. And the spherical part can rotate in the spherical hole 111 at a full angle, so that the base 110 can rotate around the spherical part at the full angle, the base 110 can be attached to the ground to the maximum extent when the leveling device 100 is adjusted at the full angle to support the container, the stability of the container on the ground is ensured, the function of adjusting the container at the full angle by the leveling device 100 is realized, the full-angle micro-leveling is realized rapidly, the response speed of the container and related equipment is effectively improved, and the adaptability of the container and related equipment in multi-scene application is effectively enhanced.

The spherical portion may in particular be formed by a spherical screw 123 to facilitate the connection between the spherical portion and the screw 121. With particular reference to fig. 1 and 2, the ball screw 123 includes a ball head 124 and a first screw 125. The ball head 124 can form a spherical portion. A second female screw hole to be engaged with the first screw 125 is provided at a lower portion of the screw rod 121. The connection between the spherical portion and the lead screw 121 is achieved by screwing the first screw 125 into the second internally threaded hole.

The threads of the first screw 125 and the second internally threaded hole may be configured as trapezoidal threads to effectively enhance the engagement strength of the threads of the first screw 125 and the second internally threaded hole, and further enhance the connection strength between the ball head 124, i.e., the spherical portion, and the lead screw 121.

To avoid the spherical portion falling out of the spherical hole 111 of the base 110, the base 110 preferably further comprises a cover plate 115, see in particular fig. 2. A cover plate 115 is attached to the top of the boss 114, such as by a third fastener 118, such as a screw, to the upper surface of the boss 114.

A cover plate hole 116 is formed in the cover plate 115 at a position corresponding to the spherical portion, and the cover plate hole 116 is matched with the spherical portion to accommodate the spherical portion. In the axial direction of the screw 121, a cover plate hole 116 penetrates the cover plate 115 to facilitate connection of the spherical portion with the screw 121 through the cover plate 115.

The lower part of the screw rod 121 is provided with a first external thread, and the first external thread is used for being matched with a first thread through hole of a support 140 to be mentioned later, so that when the screw rod 121 rotates around the axis of the screw rod, the screw rod can drive the base 110 to lift under the matching of the first external thread and the first thread through hole, the lifting function of the full-angle fine-adjustment leveling device 100 is realized, the base 110 is attached to the ground to the maximum extent, and the stability of the container falling to the ground is ensured.

To facilitate rotation of the screw 121 about its own axis, a hexagonal socket 126 is preferably provided in the top of the screw 121 to accommodate the use of the rotating screw 121 with a tool.

After the base 110 is attached to the ground, referring to fig. 7 in particular, in order to avoid the screw rod 121 continuing to rotate under the action of external force, thereby affecting the leveling support of the full-angle fine-adjustment leveling device 100 on the container, the adjusting structure 120 preferably further includes a first fastening member 122. The first fastening member 122 is provided at an upper portion of the screw rod 121 for fastening the screw rod 121 and the holder 140 to fix the screw rod 121.

In the embodiment shown in fig. 7, the first fastening member 122 is configured as a compression nut, which is inserted over the upper portion of the lead screw 121. After the base 110 is attached to the ground to form a leveling supporting effect on the container, the lead screw 121 can be fixed by screwing the compression nut.

The bolting configuration 130 is used to form a bolted connection with the bottom corner fitting 160 of the container.

Specifically, the latching structure 130 includes a latching member 131. The fastening member 131 includes a connecting portion 132, a stopper portion 133, and a connecting rod 134, which are connected in sequence.

The connecting portion 132 is used to penetrate into a corner hole of a bottom corner 160 of the container to establish a connection with the container. The connecting portion 132 is preferably constructed in a plate shape similar to the shape of the corner fitting hole and is disposed perpendicular to the connecting rod 134 so that the connecting portion 132 penetrates the corner fitting hole.

The connecting portion 132 can rotate in the bottom corner piece 160 after penetrating the corner piece hole. The length of the connecting portion 132 is set to be smaller than the length of the corner piece hole and larger than the width of the corner piece hole, so that the connecting portion 132 moves in the horizontal direction towards the corner piece hole after rotating for a certain angle in the bottom corner piece 160 until abutting against the inner side wall of the corner piece hole, reaches the bolting position, and forms a bolting connection with the bottom corner piece 160.

The connecting rod 134 can move in the horizontal direction and can drive the connecting portion 132 to pass into or out of the corner fitting hole in the horizontal direction when moving in the horizontal direction. The connecting rod 134 can also rotate around its own axis to rotate the connecting portion 132 in the bottom corner piece 160, and after the connecting portion 132 is rotated by a certain angle, it moves again in the horizontal direction to bring the connecting portion 132 to the bolting position.

To facilitate determining the angle at which the connecting portion 132 is rotated within the bottom corner piece 160, the full-angle fine-adjustment leveling device 100 preferably further includes a handle pin 150, which is specifically referred to fig. 1 and 2. A third threaded through hole is provided at the tail of the connecting rod 134, and the axis of the third threaded through hole is parallel to the longitudinal center line of the connecting portion 132. The handle pin 150 includes a second external thread that mates with the third threaded through hole, such as by providing a second external thread in the middle of the handle pin 150. After the handle pin 150 is inserted into the third threaded through hole, the axis of the handle pin 150 is parallel to the longitudinal center line of the connecting portion 132. The connecting rod 134 can be conveniently rotated by manipulating the handle pin 150, and the rotation angle of the connecting part 132 in the bottom corner piece 160 can be judged by the rotation angle of the handle pin 150.

The stopper 133 is different in shape from the connecting rod 134, and the connecting rod 134 has a size smaller than that of the stopper 133 in a radial direction of the connecting rod 134. The stopper 133 is adapted to cooperate with a stopper hole 141 of the holder 140, which will be described later, to fix the connecting portion 132 in the bolting position, preventing the connecting portion 132 from being rotated further out of the bolting position.

The bracket 140 is disposed above the base 110 and includes a first threaded through hole, a stopper hole 141, and a second through hole 142 that are respectively engaged with the first external thread, the stopper 133, and the connecting rod 134.

The connecting rod 134 is disposed in the second through hole 142 and extends out through the second through hole 142. The connecting rod 134 can move in the second through hole 142 along the horizontal direction to drive the connecting portion 132 to penetrate into or out of the corner piece hole of the bottom corner piece 160, and drive the stopping portion 133 to be separated from or enter into the stopping hole 141 of the support 140, as shown in fig. 4 to 6.

In a state where the connecting portion 132 penetrates into the corner fitting hole and the stopper portion 133 is disengaged from the stopper hole 141, the connecting rod 134 can rotate about its axis to rotate the connecting portion 132 in the bottom corner fitting 160. The connecting rod 134 drives the connecting portion 132 to rotate a certain angle in the bottom corner piece 160, and then moves along the horizontal direction again, so as to drive the connecting portion 132 to move toward the corner piece hole until the connecting portion 132 abuts against the inner side wall of the corner piece hole, and reaches the bolting position, and the stopping portion 133 enters the stopping hole 141, specifically referring to fig. 6, so as to prevent the connecting portion 132 in the bolting position from rotating continuously and separating from the bolting position.

The center line of the protruding block 114 provided with the spherical hole 111 is preferably closer to the connecting portion 132 than the center line of the horizontal plate 113 of the base 110 along the axial direction of the connecting rod 134, so as to avoid interference between the base 110 and the bottom corner piece 160 when the connecting portion 132 penetrates into the corner piece hole and forms a bolted connection with the bottom corner piece 160.

In order to prevent the connecting rod 134 from moving in the horizontal direction under the action of external force to cause the connecting part 132 to be separated from the bolting position after the connecting rod 134 drives the connecting part 132 to the bolting position, the bolting structure 130 preferably further comprises a second fastening member 135. A second fastening member 135 is provided at the rear of the connecting rod 134 for fastening the connecting rod 134 and the bracket 140 to fix the connecting rod 134 and thus the bolt 131.

In the embodiment shown in fig. 4-7, the second fastener 135 is configured as a lock nut. A third external thread matched with a locking nut is arranged at the tail part of the connecting rod 134, and the locking nut is sleeved at the tail part of the connecting rod 134. After the connecting rod 134 drives the connecting portion 132 to the latching position, the locking nut is tightened to secure the connecting rod 134 and thus the latching member 131.

In the embodiment shown in fig. 1 and 2, the cross-sections of the stopper portion 133 and the stopper hole 141 are each configured as a rectangle to effectively simplify the structures of the stopper portion 133 and the stopper hole 141. In embodiments that are not shown, the cross-section of the stop 133 and the stop hole 141 can also be configured in other shapes, such as triangular, trapezoidal, etc. As long as the shape of the stopper 133 is different from that of the connecting rod 134, and the connecting rod 134 has a size smaller than that of the stopper 133 in the radial direction of the connecting rod 134.

The first threaded through hole and the second threaded through hole 142 are preferably arranged at an interval, with particular reference to fig. 3, and the center line of the first threaded through hole is perpendicular to the center line of the second threaded through hole 142, so as to connect the lead screw 121 and the connecting rod 134 of the bolt 131 to the support 140, respectively, to avoid the generation of motion interference between the lead screw 121 moving in the vertical direction and the connecting rod 134 moving in the horizontal direction.

To facilitate the insertion of the connecting portion 132 into the corner fitting hole and into the interior of the bottom corner fitting 160 under the urging of the connecting rod 134, the support 140 preferably includes a guide portion 144. The guide portion 144 is disposed adjacent to the connecting portion 132, and a guide block 145 and a stopper block 146. The guide 144 can pass into or out of the corner fitting hole. The guide portion 144 can guide the movement of the connecting portion 132 in the bottom corner fitting 160 when it penetrates the corner fitting hole.

The stopper has a size larger than that of the guide block 145 in a radial direction of the connection rod 134. As the guide portion 144 passes into the corner fitting hole, the stop block 146 can abut against the bottom corner fitting 160 to secure the guide block 145 in place in the corner fitting hole to facilitate guiding of the connecting portion 132 by the guide portion 144.

To facilitate the arrangement of the first threaded through hole, the stop hole 141 and the second through hole 142, the holder 140 further includes a body portion 143. The body portion 143 is connected to the stopper block. The first and second through holes 142 and 141 are provided in the body portion 143 and the stopper hole 142 and the guide portion 144.

The body portion 143 preferably has a size smaller than that of the stopper in a radial direction of the connecting bar 134 to reduce the consumption of the cradle 140.

The use of the full-angle fine-adjustment leveling device 100 according to the preferred embodiment of the present invention will be described in detail with reference to fig. 4 to 7.

In using the full-angle fine adjustment leveling device 100 according to the preferred embodiment of the present invention, the second fastening member 135 such as a lock nut is first loosened, and then the connecting rod 134 is moved in the horizontal direction, so that the connecting portion 132 is vertically inserted into the corner piece hole and enters the bottom corner piece 160 by the driving of the connecting rod 134. The support 140 is then moved in a horizontal direction so that the guide block 145 at the front of the support 140 enters the corner fitting hole until the stop block abuts the bottom corner fitting 160, as shown in particular in fig. 4.

The connecting rod 134 is then moved further in the horizontal direction so that the connecting portion 132 continues to extend horizontally into the bottom corner fitting 160 until the stop block is completely disengaged from the stop hole 141, as shown in particular in fig. 5.

Subsequently, the handle pin 150 is rotated, for example, by 90 °, so that the handle pin 150 is rotated from the vertical state to the horizontal state, and the connecting portion 132 is also rotated from the vertical state to the horizontal state in synchronization. The connecting rod 134 is then moved horizontally towards the corner piece hole, i.e. the connecting rod 134 is pulled back until the connecting portion 132 abuts against the inner side wall of the corner piece hole to reach the latching position, and the stopping portion 133 enters the stopping hole 141 again to prevent the connecting portion 132 from rotating further to disengage from the latching position, and then the second fastening member 135, such as a lock nut, is tightened to achieve the latching connection of the latching member 131 to the bottom corner piece 160, as shown in fig. 6.

Then, the first fastening member 122 such as a compression nut is loosened, and the screw rod 121 is rotated by the engagement of the socket wrench tool with the socket hole 126, thereby lowering the base 110 so that the base 110 is gradually brought into contact with the ground. In the process that the rotating screw rod 121 drives the base 110 to continuously descend, the base 110 can rotate around the spherical part to continuously adjust the angle, and the maximum fit with the ground is realized.
