[0040] Embodiment 1:

[0041] like Figure 1-Figure 8 As shown, in this embodiment, when promoting the rural landscape, first remove the clamping block 16 from the installation frame 11, press the connecting shaft 14, so that the connecting shaft 14 moves downward. At the same time, the bottom of the connecting shaft 14 squeezes the second elastic member 118, and the second elastic member 118 is elastically deformed. When the connecting shaft 14 moves downward, it drives the second limit block 119 to move downward along the third slide groove 116. When it moves to the bottom end of the third slide groove 116, the connecting shaft 14 is rotated so that the connecting shaft 14 drives the second limit block 119 to move along the connecting groove 117. When it moves to the other end of the connecting groove 117, the connecting shaft 14 is loosened. At this time, the second elastic member 118 is relieved of the force, and the second elastic member 118 elastically resets to push the connecting shaft 14 to pop out of the accommodating hole 114. The connecting shaft 14 drives the second limit block 119 to slide out along the second slide groove 115, thereby removing the connecting shaft 14 from the accommodating hole 114 and removing the connecting shaft 14 from the installation frame 11.

[0042] Furthermore, the winding roller 24 with the rural landscape painting scroll 22 wound up is connected to the connecting shaft 14 through a torsion spring, and the other end of the painting scroll 22 is clamped with the sliding rod 21, and then the connecting shaft 14 is aligned with the accommodating hole 114 and squeezed to make the second limit block 119 move downward along the second slide groove 115. At this time, the second elastic member 118 is stressed and elastically deformed, and applies an upward thrust to the connecting shaft 14. When it moves to the lower end of the second slide groove 115, the connecting shaft 14 is rotated so that the connecting shaft 14 drives the second limit block 119 along the second slide groove 115. The connecting groove 117 moves, and when it moves to one end of the connecting groove 117, the connecting shaft 14 is sent away. At this time, the second elastic member 118 is relieved of the force, and the second elastic member 118 is elastically reset, thereby pushing the connecting shaft 14 to move upward, and the connecting shaft 14 drives the second limit block 119 to slide into the third slide groove 116, thereby fixing the connecting shaft 14, and then the clamping block 16 is installed on the installation frame 11, and the second slider 171 set in the connecting groove 17 opened on the clamping block 16 is installed on the top of the sliding rod 21, completing the installation of the scroll 22 in the installation frame 11.

[0043] Through the above operation, the mobile rural landscape display and promotion device can quickly disassemble the connecting shaft 14 in the installation frame 11, thereby replacing the winding roller 24 on the connecting shaft 14, and then replacing the scroll 22, so as to promote and display different landscapes.

[0044] Embodiment 2:

[0045] Reference Figure 2-Figure 8This embodiment is different from the first embodiment in that: after the winding roller 24 and the picture roll 22 are installed, the motor 26 is started so that the output end of the motor 26 drives the wire winding roller 27 to rotate, and the wire winding roller 27 reels the connecting rope 23 when rotating, so that the connecting rope 23 pulls the sliding rod 21 to move, and the sliding rod 21 pulls the picture roll 22 to unfold. The picture roll 22 pulls the winding roller 24 to rotate.

[0046] Furthermore, the bottom and top of the sliding rod 21 pass through the first sliding block 15 and the second sliding block 171 respectively. When the connecting rope 23 pulls the sliding rod 21 to move, the sliding rod 21 drives the first sliding block 15 to slide in the first sliding groove 12, drives the second sliding block 171 to slide from the connecting groove 17 into the first sliding groove 12, and continues to slide synchronously with the first sliding block 15. When sliding to the other end of the first sliding groove 12, at this time, the first sliding block 15 and the second sliding block 171 are both in contact with the first limiting block 111. As the first sliding block 15 and the second sliding block 171 continue to move, the first sliding block 15 and the second sliding block 171 squeeze the first limiting block 111 at the same time, and the first sliding block 15 squeezes the first limiting block 111. 1, so that the first limit block 111 slides into the limit hole 110, and the second slider 171 squeezes the first limit block 111, so that the first limit block 111 slowly slides into the limit hole 110 along the direction of the connecting hole 18. At this time, the first limit block 111 squeezes the first elastic member 112, and the first elastic member 112 is elastically deformed under the force, pushing the connecting rod 113 to move outward along the through hole 19. When the first slider 15 and the second slider 171 pass through the first limit block 111, at this time, the first elastic member 112 is relieved of the force, and the first elastic member 112 is elastically reset, thereby pushing the first limit block 111 out of the limit hole 110, thereby limiting the first slider 15 and the second slider 171.

[0047] Furthermore, the motor 26 is stopped from rotating because the winding roller 24 is connected to the connecting shaft 14 via a torsion spring. When the motor 26 does not rotate, the torsion spring is released from stress and resets. However, the first limit block 111 limits the first slider 15 and the second slider 171, so the torsion spring cannot be reset.

[0048] Through the above operation, the device can drive the connecting rope 23 to move through the motor 26, and the connecting rope 23 drives the sliding rod 21 to continue to move, and the sliding rod 21 pulls the picture scroll 22 to unfold, so as to facilitate the display of the rural landscape.

[0049] Embodiment three:

[0050] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, this embodiment is basically the same as the second embodiment, with the difference that: when display is not needed, the connecting rod 113 can be pulled to make the connecting rod 113 drive the first limit block 111 to slide into the limit hole 110, thereby releasing the first limit block 111 from limiting the first slider 15 and the second slider 171. At this time, the torsion spring is reset, and the torsion spring drives the winding roller 24 to rotate. When the winding roller 24 rotates, the scroll 22 continues to be wound, and the scroll 22 pulls the sliding rod 21 to move, and the sliding rod 21 pulls the connecting rope 23 to reset, so that other scrolls 22 can be unfolded when used next time.

[0051] Through the above operation, the picture roll 22 can be automatically rolled up without manual rolling, which saves time and labor, and also does not damage the picture roll 22.

[0052] It should be noted that: an electric telescopic rod is provided at the bottom of the device for adjusting the height of the device, and a rotating wheel is provided at the bottom of the electric telescopic rod to facilitate the movement of the device.

[0053] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
