[0034] like Figure 4-6 See Figure 1-3The expansion frame 1 includes a bottom steel bar 11, a plurality of steel square tubes 12 vertically welded on the bottom steel bar 11, a square tube top beam 13 welded on the top of the steel square tube 12, a motor assembly frame 14 welded on the first steel square tube at the head end, a motor drive shaft mounting seat 15 arranged on the steel square tube and cooperating with the square tube top beam 13 to assemble the electric drive mechanism 3, and a tensioning wheel seat 16 arranged on the steel square tube 12 and cooperating with the electric drive mechanism 3 to control the opening and closing of the acrylic shelf 2; the acrylic shelf 2 includes an acrylic plate body 21, one end of which is connected to the acrylic plate body 21 A movably mounted support rod 22, the other end of which is hingedly mounted to the steel square tube 12, and a rotating shaft 23 assembled on the acrylic plate 21; the electric drive mechanism 3 includes a servo motor 31 fixedly mounted on the motor assembly frame 14, a motor drive shaft 32 fixedly connected to the output end of the servo motor 31 and assembled through the motor drive shaft mounting seat 15, a winding drum 33 fixedly mounted on the motor drive shaft 32 and with the mounting position corresponding to the tensioning wheel seat 16, and a steel rope 34 with one end fixedly connected to the support rod 22 and the other end wound on the winding drum 33.

[0035] It should be further explained that the external expansion frame uses structural parts such as bottom steel bars and steel square tubes, which are reasonably designed and can provide sufficient support and stability to ensure that the acrylic shelf is not easily deformed or tilted by external forces during use. In addition, the electric drive mechanism controls the operation of the motor to achieve the opening and closing control of the acrylic shelf, which is simple and convenient to operate. More importantly, the tension of the acrylic shelf can be adjusted through the design of the tension wheel seat and steel rope, so as to adapt to the needs of different environments and ensure that the opening and closing effect of the acrylic shelf is more ideal.

[0036] In this solution, a hinge seat 121 is welded to the upper end of the steel square tube 12 to facilitate the assembly of the support rod 22 with the hinge seat 121 through the hinge shaft.
