After expanding, the position of the transmission seat 301 is limited by the limit assembly 400 to ensure the stability of the transmission seat 301 and the transmission rod 302, thereby ensuring the stability of the frame assembly 200. Further, when the driving screw 101 is rotated counterclockwise, it will drive the transmission rod 302 to push the frame assembly 200, so that the frame assembly 200 can be folded and stored for easy transportation and storage.

[0023] Reference Figure 2-3 Both fixing seats 100 are provided with connecting grooves 102 for connecting the skeleton assembly 200. Specifically, the connecting grooves 102 are grooves provided on the fixing seats 100 and have a flat bottom wall. When the skeleton assembly 200 is fully expanded, the bottom wall of the first connecting rod 201 abuts against the bottom wall of the connecting groove 102.

[0024] Reference Figure 1-4 The skeleton assembly 200 includes two first connecting rods 201 rotatably connected to two fixed seats 100 and a second connecting rod 202 rotatably connected between the two first connecting rods 201. Specifically, when the driving screw rod 101 drives the transmission seat 301 to move downward, the transmission rod 302 is set to generate a corresponding pulling force on the first connecting rod 201, thereby driving the first connecting rod 201 to rotate clockwise along the connecting groove 102, thereby opening the skeleton assembly 200. Correspondingly, when the driving screw rod 101 is rotated counterclockwise, it will drive the transmission rod 302 to generate a corresponding thrust on the first connecting rod 201, thereby folding the skeleton assembly 200.

[0025] Reference Figure 1-3 Furthermore, the skeleton assembly 200 is provided with several groups in a ring shape along the two fixing seats 100. In order to ensure the stability of the skeleton assembly 200 after being expanded, the transmission assembly 300 is provided with two groups axially along the driving screw rod 101, and its output ends are respectively connected to the upper and lower first connecting rods 201.

Specifically, when in use, after the skeleton assembly 200 is expanded or folded by driving the screw rod 101, the position of the positioning plate 404 is limited by the positioning nut 403, thereby limiting the position of the two transmission seats 301, ensuring the stability of the transmission seat 301 and the transmission rod 302, and thereby improving the stability of the skeleton assembly 200.

[0027] Reference Figure 1 , Figure 2 and Figure 4 In order to facilitate the rotation of the driving screw rod 101, a connecting sleeve 103 is provided on the fixing seat 100 below, and one end of the driving screw rod 101 passes through the fixing seat 100 and is connected to a handle 104.

[0028] Specifically, when the internally supported colored lantern skeleton is in use: the skeleton assembly 200 needs to be opened, the connecting sleeve 103 is held by hand, and the driving screw rod 101 is rotated clockwise through the handle 104 to drive the transmission seat 301 to move downward, and the transmission rod 302 provided will generate a corresponding pulling force on the first connecting rod 201, thereby driving the first connecting rod 201 to rotate clockwise along the connecting groove 102, thereby opening the skeleton assembly 200. Correspondingly, when the driving screw rod 101 is rotated counterclockwise, the transmission rod 302 will be driven to generate a corresponding thrust on the first connecting rod 201, and the skeleton assembly 200 will be folded. After the skeleton assembly 200 is opened or folded by the driving screw rod 101, the position of the positioning plate 404 is limited by the positioning nut 403, thereby limiting the position of the two transmission seats 301, ensuring the stability of the transmission seat 301 and the transmission rod 302, and thereby improving the stability of the skeleton assembly 200.
