[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-10 The present invention provides a technical solution: a movable guide device for a container transport vehicle, comprising a bearing surface 1, a groove 7, a base 2, a container body 3, a guide mechanism 4, a locking mechanism 5 and a swing arm mechanism 6, wherein the groove 7 is fixedly arranged at the upper end of the bearing surface 1, the base 2 is engaged with the groove 7, the guide mechanism 4 is located inside the base 2, the locking mechanism 5 is located inside the base 2, the swing arm mechanism 6 is located at the outer end of the locking mechanism 5, and the container body 3 is movably installed above the locking mechanism 5, the guide mechanism 4 comprises a groove 7, a guide block shaft 402, a flip guide block 403 and a guide block return spring 404, the guide block shaft 402 is movably installed inside the base 2, the flip guide block 403 is fixedly installed on the outer end of the guide block shaft 402, and one end of the guide block return spring 404 is fixedly installed on the outer end of the guide block shaft 402. The loading surface 1 is the environment in which the present device is installed and used. When the container body 3 falls, the container body 3 is on the inner side of the flip guide block 403. When the container body 3 approaches, it interferes with the flip guide block 403, causing the flip guide block 403 to flip around the guide block rotation axis 402, protecting both from damage. After the container body 3 falls, the corners of the flip guide block 403 can limit the container body 3, preventing the container body 3 from shifting outward. When the guide mechanism 4 does not need to play a guiding and limiting role, the container body 3 can fall directly on the guide mechanism 4. The mass of the container body 3 will flatten the guide mechanism 4 and will not affect the layout of the container body 3. When the container body 3 is moved away, the flip guide block 403 returns to its initial state due to the resilience of the guide block return spring 404.

[0026] The locking mechanism 5 includes a locking block 501 and a return spring 502. The locking block 501 is movably installed in the interior of the groove 7. By setting the locking mechanism 5, when the container body 3 falls onto the load-bearing surface 1, the locking block 501 is pressed downward, thereby driving the return spring 502 to compress; one end of the return spring 502 is fixedly installed at the lower end of the locking block 501, and the other end of the return spring 502 is fixedly connected to the base 2; the swing arm mechanism 6 includes a swing arm shaft 601, a locking swing arm 602, a sliding shaft 603 and a slide groove 604. The shaft 601 is fixedly installed inside the base 2, and the locking swing arm 602 is fixedly installed on the outer end of the swing arm shaft 601. By setting the swing arm mechanism 6, the slide groove 604 is driven to reciprocate along the sliding shaft 603 during the downward pressing process of the locking block 501, so that the locking swing arm 602 rotates around the swing arm shaft 601. The left end of the locking swing arm 602 is tilted upward and pressed against the flip guide block 403, so that the flip guide block 403 will not change its angle due to the rebound of the guide block return spring 404, thereby playing a role in guiding and limiting the container body 3.

[0027] The sliding shaft 603 is movably installed on the outer end of the locking block 501, and the slide groove 604 is fixedly set on the outer end of the locking swing arm 602; the flip guide block 403 is movably installed inside the groove 7, and the other end of the guide block return spring 404 is fixedly connected to the base 2; the sliding shaft 603 is adapted to the slide groove 604, and the sliding shaft 603 is movably installed inside the slide groove 604.

[0028] Working principle: When the container body 3 falls, the container body 3 is on the inner side of the flip guide block 403. When the container body 3 comes closer, it interferes with the flip guide block 403, causing the flip guide block 403 to flip around the guide block shaft 402, protecting both from damage. After the container body 3 falls, it presses the locking block 501 downward, thereby driving the return spring 502 to compress. The corner of the flip guide block 403 can limit the container body 3, and the slide groove 6 is driven during the downward pressure of the locking block 501. 04 reciprocates along the sliding shaft 603, causing the locking swing arm 602 to rotate around the swing arm rotating shaft 601, and the left end of the locking swing arm 602 tilts upward to press against the flip guide block 403, so that the flip guide block 403 will not change its angle due to the rebound of the guide block return spring 404, thereby playing a role in guiding and limiting the container body 3, and preventing the container body 3 from translating outward. When the guide mechanism 4 does not need to play a guiding and limiting role, the container body 3 can fall directly on the guide mechanism 4, and the mass of the container body 3 will flatten the guide mechanism 4 without affecting the layout of the container body 3. When the container body 3 is moved away, the flip guide block 403 returns to its original state due to the rebound force of the guide block return spring 404. Because the bottom of some container bodies 3 is uneven, the following situation may occur: the container only presses on the flip guide block 403 but not on the locking block 501. At this time, the flipping of the flip guide block 403 is not affected because there is a height difference between the flip guide block 403 and the locking block 501. Due to the height difference at the bottom of the container, there will not be a situation where the locking block 501 is only pressed to lock the flip guide block 403 and then the container falls on the flip guide block 403 to crush the flip guide block 403. In addition, the locking block 501 and the sliding shaft 603 can move relative to each other. The reason for the movement is to prevent the container from crushing the locking block 501 after the flip guide block 403 is turned down. Therefore, the force causing the relative movement will be greater than the resilience of the return spring. There are many mechanisms for achieving relative movement. Two are listed below. The first one is as shown in the attached figure. Figure 8As shown, there is a sliding groove 604 on the locking block 501, and the sliding shaft 603 can slide in the sliding groove 604 of the locking block 501. There is an elastic element such as a spring in the sliding groove 604 to ensure that the sliding shaft 603 is located at the bottom of the sliding groove 604. When the external force is greater than a critical value, the sliding shaft 603 will slide, but this critical value, as described above, will be greater than the rebound force of the return spring of the locking block 501. The second type is that the locking block 501 is divided into two parts, the sliding shaft 603 is connected to a part of the locking block 501, and the other part of the locking block 501 can slide relative to this part. There is an elastic element such as a spring in the middle to ensure the relative position of the part where the sliding shaft 603 is located and the other part. When the external force is greater than a critical value, the two parts of the locking block 501 will slide relative to each other, but this critical value, as described above, will be greater than the rebound force of the return spring of the locking block 501. This type of structure is more common and the drawings are omitted. Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
