[0046] The multi-angle gripping mechanism 3 also includes a swing arm 34, a fixed block 35 is rotatably connected to the middle of the swing arm 34, one side of the fixed block 35 is fixedly connected to the multi-angle movable plate 14, and sliding grooves are provided at both ends of the swing arm 34;

[0049] Wherein: the middle part of the receiving groove 26 is fixedly connected to the motor driving shaft.

[0050] Compared with the prior art, through the implementation of this embodiment, with the assistance of the multi-angle gripping mechanism 3, the multi-angle movable plate 14 can easily cope with various terrains, including slopes, uneven ground, etc., and can be automatically fixed to the ground during installation. The rivets 37 are fixed to the ground, and the close fit between the rivets 37 and the ground reduces the shaking and instability factors caused by uneven terrain, thereby improving the overall structural safety of the container house; further reducing the sliding and tilting phenomenon caused by the installation of the container on an inclined slope, further improving the convenience of installation, and at the same time, the present invention cleverly solves the problem of difficult installation and poor stability of container houses under different terrains.

[0051] Everything in the above example works like this:

[0052] In the initial state: the pressing plate 32 is not compressed and the motor is not started;

[0053] The following is the working process of the multi-angle gripping mechanism 3 for horizontal adjustment of the multi-angle movable plate 14:

[0054] When installing the container, first use the on-site lifting equipment to hoist the container as a whole and then install it in the designated area according to the user's requirements. When the container is placed in the area specified by the user, such as an inclined slope, Figure 4 As shown, after the container is hoisted and placed on the ground, the multi-angle movable plate 14 starts to move downward due to the gravity of the container itself. Figure 6 As shown, because the buffer spring 31 is evenly fixed under the multi-angle movable plate 14, and the other end of the buffer spring 31 is fixedly connected to the pressing plate 32, and the pressing plate 32 is fixedly slidably connected to the multi-angle movable plate 14 through the slide plate 33, when the bottom of the pressing plate 32 contacts the ground, the buffer spring 31 will be compressed due to the gravity of the container, and the multi-angle movable plate 14 will start to slide downward along the slide plate 33, because the fixed block 35 is fixedly connected to the multi-angle movable plate 14, as the multi-angle movable plate 14 slides downward, the fixed block 35 will start to slide downward synchronously;

[0055] Furthermore, because the swing arm 34 is rotatably connected to the fixed block 35, and one end of the slide groove opened at both ends of the swing arm 34 is movably connected to the slide plate 33, and the slide groove at the other end of the swing arm 34 is movably connected to the fixing column 36 fixed on the rivet 37, and because the rivet 37 is slidably connected in the vertical slide groove 38, the upward sliding of the slide plate 33 along the multi-angle movable plate 14 will drive the fixing column 36 to drive the rivet 37 to slide downward along the vertical slide groove 38. At this time, the downward sliding of the rivet 37 will cause the bottom of the rivet 37 to be inserted into the ground soil. The fixation of the rivet 37 to the ground makes the rivet 37 fit closely with the ground, reducing the shaking and instability caused by uneven terrain, thereby improving the overall structural safety of the container house; further reducing the sliding and tilting phenomenon caused by the installation of the container on an inclined slope, such as Figure 4 As shown, because the bottom of the leg 13 is spherical and rotatably connected to the multi-angle movable plate 14, the bottom of the multi-angle movable plate 14 can be fitted with the ground on different inclined grounds, and the rivet 37 is fixed to the ground under the action of the container's own gravity. When the container is transported, the rivet 37 is driven again to slide upward in the vertical slide groove 38 under the elastic action of the pressing plate 32. Through the arrangement of the present invention, with the assistance of the multi-angle gripping mechanism 3, because the bottom of the leg 13 is spherical and rotatably connected to the multi-angle movable plate 14, the bottom of the multi-angle movable plate 14 can be fitted with the ground on different inclined grounds, and the rivet 37 is fixed to the ground under the action of the container's own gravity. When the container is transported, the rivet 37 is driven again to slide upward in the vertical slide groove 38 under the elastic action of the pressing plate 32. Different inclined ground surfaces can be fitted with the ground, so that the multi-angle movable panel 14 can easily cope with various terrains, including slopes, uneven ground, etc., and can automatically fix the ground during installation. The rivets 37 are fixed to the ground, and the rivets 37 are closely fitted with the ground, which reduces the shaking and instability factors caused by uneven terrain, and improves the overall structural safety of the container house; further reduces the sliding and tilting phenomenon caused by the installation of the container on the inclined slope, and further improves the convenience of installation. At the same time, the present invention cleverly solves the problem of difficult installation and poor stability of container houses under different terrains.

[0056] Please refer to the above working process Figures 1 to 7 .

[0057] The following is the working process of the horizontal adjustment folding mechanism 2 for fixing the box body 11 at different angles:

[0058] As described above, after the container is installed as a whole, the user can adjust the overall tilt angle of the box body 11 according to his or her own preferences. At this time, because the middle part of the seesaw 21 is rotatably connected to the inner wall of the box body 11, and because the motor drive shaft installed on the inner wall of the box body 11 is fixedly connected to the middle part of the seesaw 21, the motor starts to rotate through the control of the controller under the control of the user terminal, and the seesaw 21 can be driven to start adjusting in different directions through the rotation of the motor. At this time, the adjustment is made through the ground slope, and when the ground slope is as Figure 3When the support leg 13 is tilted to the left, the user only needs to control the motor to rotate counterclockwise. At this time, the counterclockwise rotation of the motor can drive the seesaw 21 to start rotating counterclockwise. At the same time, because the two ends of the seesaw 21 are rotatably connected to the auxiliary blocks 22, and the auxiliary blocks 22 are rotatably connected to the upper surface of the leg 13, the counterclockwise rotation of the seesaw 21 will drive the support leg 13 to rotate counterclockwise. Figure 3 The left set of legs 13 shown starts to slide downward along the left inner wall of the box base 1. At this time, because its slope is inclined to the left, the left leg 13 slides downward. At the same time, because the middle part of the box body 11 is connected to the inner wall of the box base 1 by rotation, the rocker 21 rotates counterclockwise to drive the right leg 13 to start sliding upward on the inner wall of the box base 1, so that the leg 13 can drive the multi-angle movable plate 14 to quickly fit the ground;

[0059] At this time, the reverse horizontal push plate 23 is rotatably connected to the inner wall of the box base 1, because one end of the reverse horizontal push plate 23 is rotatably connected to the bottom of the box body 11, and the other end is rotatably connected to the upper surface of the support leg 13. When the support leg 13 slides downward, it always drives the reverse horizontal push plate 23 to drive the box body 11 to move in the opposite direction of the support leg 13, so that the box body 11 can always maintain a relative surface state, so that the container house of the present invention can flexibly adapt to various terrains and uneven ground, breaking the limitation that traditional container houses must be installed on a horizontal surface, greatly expanding its application range. Compared with the transmission container, the installation of the container must be carried out after the bottom of the container is horizontally laid before installation, which is not only time-consuming and labor-intensive, but also increases the labor cost. Under the setting of the present invention, the rotation of the rocker 21 can be automatically adjusted to make the box body 11 able to be installed at different inclination angles, which not only simplifies the installation process, but also reduces the additional leveling work required due to uneven terrain, thereby improving installation efficiency and reducing installation costs.

[0060] When the container is installed, the operator Figure 2 As shown, after the container is installed as a whole, the operator will pull the component handle 28 to the side away from the marked box 11 according to the instructions in the figure. This action will trigger a chain reaction. In the initial state, the support plate 27 is closed and hidden in the component storage groove 26. As the handle 28 is pulled, it will drive the component folding plate 12 connected to it to slide at the bottom of the component box 11; the component box 11 is designed with a slide arc groove 24 on both sides, and the component folding plate 12 is fixed with a component slide column 25 that can slide in the arc groove 24 on both sides. Therefore, as the folding plate 12 slides, the slide column 25 gradually moves under the guidance of the arc groove 24 until the folding plate 12 is pulled to a position that is completely flush with the bottom of the box 11

[0061] At this time, the component support plate 27 originally folded in the storage groove 26 begins to automatically unfold under the action of the built-in torsion spring. At this time, the support of the support plate 27 and the ground will enhance the stability of the overall unfolding of the container, and also provide convenience for subsequent support operations. Finally, the operator can simultaneously enhance the support effect of the support plate 27 by simply pulling the handle 28. At this time, the contact area between the support plate 27 and the ground can effectively disperse the weight of the equipment itself and the load generated during operation; this reduces the pressure per unit area, thereby reducing damage to the ground, and also improves the adaptability of the equipment under different geological conditions. Moreover, on uneven ground or in strong winds, the automatic unfolding and support of the legs can quickly adjust the equipment status to adapt to complex and changeable working conditions. This flexibility ensures the stability and reliability of the equipment in various environments. Thereby completing the last step of the entire installation process, this design cleverly combines mechanical principles with humanized operation considerations, which not only reduces the complexity of manual operation, but also significantly improves the installation speed and efficiency of the container. Compared with traditional settings, through the clever linkage designed by the present invention, the operator only needs a simple pulling action to trigger the automatic operation of the entire installation mechanism, which greatly reduces the installation steps and the time required, and significantly improves the installation efficiency.

[0062] Please refer to the above working process Figures 1 to 7 .
