As a result, the flexibility and space efficiency of the track become limiting factors. The stability of the track structure in the prior art during the extension process needs to be improved, and it often takes up more space in the folded state, which is not convenient for storage and transportation.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 7 The utility model provides a technical solution: a retractable rigid track, including a fixed plate 1, on which are installed: a driving motor 2, a pushing assembly, a head connecting rod 3, a connecting assembly, a tail connecting rod 4 and an end plate 5. The driving motor 2 is arranged on one side of the fixed plate 1 through a plurality of bolts, and the driving end extends to the other side of the fixed plate 1; the pushing assembly is arranged on the other side of the fixed plate 1 and is connected to the driving end of the driving motor 2; one end of a plurality of head connecting rods 3 are rotatably arranged on the fixed plate 1 and on the same side as the pushing assembly; the connecting assembly is movably arranged on the pushing assembly; the ends of a plurality of tail connecting rods 4 are rotatably arranged on the connecting assembly; one side of the end plate 5 is fixedly connected to a plurality of tail connecting rods 4.

[0022] In the specific implementation process, it should be noted that when the driving motor 2 is started, the threaded rod 7 is driven to rotate, and the push assembly begins to move under the limitation of the thread of the threaded rod 7 itself and the limiting effect of the head connecting rod 3. In the process of pushing the assembly to move, the connecting assembly gradually unfolds and finally becomes fully unfolded. The end plate 5 also moves with the unfolding of the connecting assembly, and the tail connecting rod 4 unfolds synchronously with the head connecting rod 3, so that the entire structure gradually extends during the movement to meet the length requirements in different actual use scenarios. The scalability adjustment of the track structure is achieved, ensuring its flexibility and adaptability under different working conditions.

[0023] In some examples, further, several tail connecting rods 4 are provided with bar-shaped through holes 6, and a movable pin is installed at each bar-shaped through hole 6. The pushing assembly includes: a threaded rod 7 and a moving plate 8, the end of the threaded rod 7 is fixedly connected to the driving end of the driving motor 2; the middle part of the moving plate 8 is screwed to the outer side of the outer wall of the threaded rod 7; wherein the moving plate 8 is arranged in a cross star shape, and a notch is provided at the protruding part, and the notch of the moving plate 8 is connected to the end of the pin.

[0024] In the specific implementation process, it should be noted that when the driving motor 2 is started and the threaded rod 7 is driven to rotate, the moving plate 8 moves along the outer wall of the threaded rod 7. As the moving plate 8 moves, its notch interacts with the latch in the bar-shaped through hole 6, and the latch slides in the notch, so that the tail connecting rod 4 moves synchronously under the push of the moving plate 8. When the track is extended and retracted, the tail connecting rod 4 can be stably maintained in an appropriate position, ensuring the firmness of the entire structure and precise telescopic control, so that the track can be flexibly extended or retracted according to actual needs.

[0025] In some examples, further, the connection component includes: a connecting block 9 and a cross bracket 10, the number of the connecting blocks 9 is multiple, and they are respectively movably connected to the ends of the head connecting rods 3 and the tail connecting rods 4; the cross brackets 10 are arranged in two groups, and a connecting block is arranged between the two groups of cross brackets 10, the connecting block is rotatably connected to the cross bracket 10, and the two ends of the two groups of cross brackets 10 are respectively connected to the connecting blocks 9 on the head connecting rod 3 and the tail connecting rod 4.

[0026] In the specific implementation process, it should be noted that when the push assembly moves along the threaded rod 7 driven by the driving motor 2, the interaction between the notch of the moving plate 8 and the latch causes the tail connecting rod 4 to move synchronously, and the angle of the head connecting rod 3 changes. Under the action of the connecting block 9, the two groups of cross brackets 10 begin to unfold. During the telescopic process, the connecting assembly can effectively increase the length of the structure and maintain the overall stability. The cross brackets 10 can be set as multiple groups according to the actual usage, and each group of cross brackets 10 is still connected by the connecting block.

[0027] During the extension and retraction process of the track, when the driving motor 2 starts and drives the threaded rod 7 to rotate, the push assembly moves along the threaded rod 7, and the notch of the moving plate 8 interacts with the latch, so that the tail connecting rod 4 and the connecting block 9 move synchronously. Since the number of cross brackets 10 can be set to multiple groups according to actual usage, the cross brackets 10 are interconnected by connecting blocks to form a flexible support network. As the track is extended and retracted, the connecting blocks allow the cross brackets 10 to rotate relative to each other, thereby achieving the unfolded and folded states. The connecting blocks achieve synchronization between each group of cross brackets when unfolding or folding, and at the same time help to adapt to the needs of different lengths while maintaining the stability and strength of the track structure. The provision of multiple groups of cross brackets 10 not only increases the extension range of the track, but also ensures smooth operation and structural integrity throughout the entire extension process, thereby making the track system more adaptable to complex and changeable usage environments.

[0028] In some examples, further, each group of cross supports 10 is composed of a plurality of rotating plates, wherein two rotating plates form a group, and the middle parts of the two rotating plates are connected by rotation. The two rotating plates are in an X shape when unfolded and in an H shape when folded.

[0029] In the specific implementation process, it should be noted that the rotating plate in each group of cross brackets 10 plays a key role in the extension and contraction process of the track. In the unfolded state, every two rotating plates are in an X shape, which can increase the length of the track, and in the folded state, the rotating plate will be transformed into an H shape, which helps to reduce the space occupied by the track when it is contracted, and is convenient for storage and transportation. With the start of the drive motor 2 and the rotation of the threaded rod 7, the movement of the push assembly will drive the two rotating plates that fit together to open and close, and then the rotating plates will rotate relative to each other at the rotating connection in the middle part, realizing the conversion from X shape to H shape or from H shape to X shape. The scalability and adaptability of the track system are enhanced, so that it can flexibly adjust its own shape and length according to different usage scenarios and space requirements. This not only improves the practicality of the track, but also enhances its function and convenience of operation.
