[0023] See also Figure 1-Figure 6 A display stand with variable height includes a display stand body 1 and an adjustment mechanism 2 arranged inside the display stand body 1. The display stand body 1 includes a frame body 101:

[0024] Furthermore, the adjustment mechanism 2 includes two corresponding rotating rods 202, the tops of the two rotating rods 202 extend to the top of the frame 101 and are fixedly connected to the power motor 201, a plurality of first gears 203 are equidistantly fixedly connected to the surface of the rotating rod 202, the front and rear sides of the first gear 203 are meshingly connected to the second gear 204, the inner wall of the second gear 204 is fixedly connected to a threaded sleeve 205, the surface of the threaded sleeve 205 is rotatably connected to a mounting seat 206, the internal thread of the threaded sleeve 205 is threadedly connected to a threaded rod 207, the top of the threaded rod 207 extends to the top of the threaded sleeve 205 and is connected and fixedly connected to the display mechanism 3.

[0025] When the height spacing between the display mechanisms 3 needs to be adjusted, the operator can start the power motor 201, and the power motor 201 drives the rotating rod 202 to rotate along the left and right sides of the inner wall of the frame 101. When the rotating rod 202 rotates, it drives multiple first gears 203 on its surface to rotate coaxially. The rotation of the first gear 203 drives the second gear 204 meshing with it to rotate. When the second gear 204 rotates, it drives the threaded sleeve 205 to continuously rotate along the inner wall of the mounting seat 206. When the mounting seat 206 rotates, it drives the threaded rod 207 to rotate with the mounting seat 206 and passes through the limit The cooperation between the block 208 and the limiting groove 102 drives the threaded rod 207 to move upward along the inner wall of the frame 101. When the threaded rod 207 moves upward, it drives the display mechanism 3 to be lifted upward so as to adjust the height of the spacing of each layer of the display mechanism 3. This device adjusts the spacing of each layer of the display mechanism 3 to a suitable distance according to different display requirements, which greatly enhances the adaptability of the display frame to the display of goods of different specifications. The display frame effectively solves the limitation of the fixed layer spacing of the traditional display frame through the ingenious mechanical structure design, and is a new type of display frame product integrating intelligence and flexibility.

[0026] Furthermore, a limiting block 208 is fixedly connected to one side of the top of the threaded rod 207, limiting grooves 102 are fixedly provided on the left and right sides of the inner wall of the frame 101, a base 103 is fixedly connected to the bottom of the frame 101, and the limiting block 208 and the limiting groove 102 are slidably connected.

[0027] A limit block 208 is fixedly connected to one side of the top of the threaded rod 207. This design is to ensure that the threaded rod 207 will not be excessively screwed out during the up and down movement, and to play a role of safety limit and guidance, thereby preventing the display mechanism 3 from being unstable or damaged due to excessive rise. The limit block 208 is slidably connected to the limit groove 102. This design ensures that the threaded rod 207 and the display mechanism 3 connected thereto can only move in the vertical direction, further ensuring the stability of the display frame during the adjustment process.

[0028] Furthermore, one side of the mounting seat 206 is fixedly connected to the inner wall of the frame 101 , the bottom of the rotating rod 202 is rotatably connected to the bottom of the inner wall of the frame 101 , and the bottom of the power motor 201 is fixedly connected to the top of the frame 101 .

[0029] The device has a compact structure and stable operation. It can realize accurate and convenient adjustment of the height of each layer of the display rack by driving the power motor 201. It not only embodies the humanized design concept, but also fully considers the practicality and safety of the display function.

[0030] Furthermore, a fixing sleeve 209 is fixedly connected to the top of the threaded rod 207, and a display mechanism 3 is clamped inside the fixing sleeve 209. The display mechanism 3 includes a fixing rod 302, and the left and right ends of the fixing rod 302 are fixedly connected to fixing blocks 301. One side of the fixing rod 302 is fixedly connected to multiple connecting rods 303, and the bottom of the connecting rod 303 is fixedly connected to the first display board 304 and the second display board 305.

[0031] The main function of the fixing sleeve 209 is to convert the movement of the threaded rod 207 into the vertical movement of the display mechanism 3, and at the same time fix the display mechanism 3 by means of a clamping connection, so that the display mechanism 3 can move up and down synchronously with the lifting and lowering of the threaded rod 207. The bottom of the connecting rod 303 is fixedly connected with the first display board 304 and the second display board 305. These display boards are the parts that directly carry the displayed items and can be arranged and adjusted according to the characteristics and quantity of the displayed goods. The device cleverly uses the principle of mechanical transmission, which not only realizes the free adjustment of the display frame height, but also constructs a display board structure that can flexibly adapt to different display needs, which fully reflects the humanization and practicality of the design.

[0032] Furthermore, a pin shaft 210 is provided at the lower interior of the fixing sleeve 209, a positioning rod 212 is slidably connected to the top of the fixing sleeve 209, a positioning slot 306 and a pin shaft slot 307 are respectively provided at the top and bottom of the fixing block 301, the positioning slot 306 and the bottom of the positioning rod 212 are mutually clamped, and the bottom of the pin shaft slot 307 and the top of the pin shaft 210 are mutually clamped.

The bottom of the pin slot 307 and the top of the pin 210 are mutually engaged, further strengthening the fixing strength and stability of the display mechanism 3 on the display frame, ensuring that the display mechanism 3 can be firmly and reliably fixed at any height, thereby ensuring the display effect and safety.

[0034] Furthermore, a spring 211 is fixedly connected between the fixing sleeve 209 and the pin shaft 210 , and the top of the positioning rod 212 extends to above the fixing sleeve 209 and is fixedly connected to a handle.

[0035] A spring 211 is added between the fixing sleeve 209 and the pin shaft 210, so that the display mechanism 3 has a certain buffering capacity in the unlocked state. When the display mechanism 3 is subjected to a slight impact or vibration, the spring 211 can absorb part of the energy, reducing the impact on the display mechanism 3 itself and the internal display items, thereby improving the stability and durability of the device. The addition of the handle facilitates the user to manually operate the positioning rod 212. By pulling or pressing the handle, the user can easily connect or separate the positioning rod 212 with the positioning slot 306 on the fixing block 301, thereby realizing rapid locking and unlocking of the display mechanism 3. This humanized design greatly simplifies the operating process of adjusting the height of the display stand and improves work efficiency.

[0036] Furthermore, the frame 101 is made of stainless steel.

[0037] Stainless steel material has high strength and hardness, making the display rack structure sturdy and durable, able to withstand heavy display items without deformation, ensuring the stability and safety of the display rack during use.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
