[0024] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figures 1 to 4 The utility model provides a reinforced lifting sign 33, including a base 1 and a mounting platform 3. A lifting component 2 is arranged on the top surface of the base 1, and the lifting component 2 drives the mounting platform 3 to move up and down. A sign 33 is installed on one side of the mounting platform 3. A supporting connecting rod 313 is rotatably arranged on the peripheral side of the bottom end of the mounting platform 3. A buffer seat 13 movably connected to the base 1 is arranged on the peripheral side of the base 1. One end of the supporting connecting rod 313 away from the mounting platform 3 is rotatably connected to the buffer seat 13. The buffer seat 13 moves away from or close to the base 1 under the drive of the mounting platform 3.

[0026] In the technical solution provided by the utility model, when the lifting assembly 2 drives the identification plate 33 on the mounting platform 3 to move up and down, the mounting platform 3 is supported by the support connecting rod 313 arranged around the bottom end of the mounting platform 3, and the movable buffer seat 13 connected to the support connecting rod 313 provides additional supporting force or pulling force to balance the force on the mounting platform 3 after the identification plate 33 is installed. This design enables the mounting platform 3 to remain stable during the up and down movement even when subjected to external force, and is not prone to tilting or collapse. Moreover, since an additional reinforcement structure is provided, there is no need to perform other reinforcement on site, and the identification plate can be directly arranged.

[0027] Please refer to Figures 1 to 4 In this embodiment, a support column 11 is provided on the top surface of the base 1, and a motor mounting seat 12 is provided on the top of the support column 11. The lifting assembly 2 includes a driving motor 21 and a transmission screw 22. The driving motor 21 is installed on the top surface of the motor mounting seat 12. The output shaft of the driving motor 21 passes through the motor mounting seat 12 and is connected to the transmission screw 22. The mounting platform 3 is sleeved on the transmission screw 22. The support column 11 extends vertically upward, and the support column 11 provides a solid supporting foundation for the entire device. The motor mounting seat 12 on the top of the support column 11 is used to install and fix the driving motor 21. This design enables the driving motor 21 to be stably fixed on the upper part of the device, avoiding shaking during the lifting process caused by the unstable position of the motor.

[0028] Please refer to Figures 1 to 4In the present embodiment, the mounting platform 3 includes a screw seat 31 and a connecting sleeve 32. The screw seat 31 is connected to the transmission screw 22 in a transmission manner. Three first hinge seats 311 are equidistantly arranged on the side of the screw seat 31. The support connecting rod 313 is connected to the first hinge seat 311, and the connecting sleeve 32 is arranged at the top of the screw seat 31. The first hinge seat 311 provides a connection point for the support connecting rod 313, and the support connecting rod 313 is connected to the first hinge seat 311 in a hinged manner, forming a stable supporting structure. When the mounting platform 3 is raised or lowered, the support connecting rod 313 can be extended and retracted accordingly, playing a role of balance and stability. This design makes it difficult for the mounting platform 3 to shake or tip over during the lifting process, thereby improving the safety and reliability of use.

[0029] Please refer to Figures 1 to 4 In this embodiment, the buffer seat 13 is provided with a second hinge seat 131, and the support link 313 is connected to the second hinge seat 131. Corresponding to the first hinge seat 311, when the mounting platform 3 may shake or tilt due to gravity, wind or other external factors during the lifting process, the support link 313 is connected to the buffer seat 13 through the second hinge seat 131, which can provide additional support and balance. This design can significantly enhance the stability of the mounting platform 3 and ensure that it remains stable during the lifting process.

[0030] Please refer to Figures 1 to 4 In this embodiment, a counterweight pad 132 is provided on both sides of the second hinge seat 131. The counterweight pad 132 is used to balance the weight change of the mounting platform 3 and the identification plate 33 during the lifting process, ensuring a smoother lifting process.

[0031] Please refer to Figures 1 to 4 In this embodiment, at least two first guide seats 321 are arranged on the surface of the connecting sleeve 32, and the first guide seats 321 are sleeved on the support column 11, and the first guide seats 321 are connected to the identification plate 33. The first guide seats 321 mainly play a guiding role, so that the mounting platform 3 moves up and down along the extension direction of the support column 11, reducing the shaking generated during the movement.

[0032] Please refer to Figures 1 to 4 In this embodiment, the signboard 33 is connected to the first guide seat 321, and a plurality of LED lights 331 are provided on the surface of the signboard 33. The LED lights 331 on the surface of the signboard 33 can provide sufficient lighting to ensure that the signboard 33 is still clearly visible at night or when light is insufficient, thereby improving the practicality and visibility of the signboard 33.

[0033] Please refer to Figures 1 to 4In this embodiment, a second guide seat 312 is provided on the side of the screw seat 31, and the second guide seat 312 is sleeved on the support column 11. The second guide seat 312 is sleeved on the support column 11, which ensures the stability of the transmission screw 22 and the mounting platform 3 during the lifting process. Through the precise matching of the guide seat, the shaking of the screw and the mounting platform 3 during movement can be reduced, ensuring the stability and accuracy of the lifting process.

[0034] Please refer to Figures 1 to 4 In this embodiment, a slider 133 is provided on the side of the buffer seat 13 facing the base 1, and a stopper 134 is provided at the end of the slider 133. A matching portion 14 is provided on the side of the base 1 facing the buffer seat 13. The matching portion 14 is provided with a first hole section 141 and a second hole section 142 connected to the first hole section 141. The slider 133 is slidably matched with the first hole section 141, and the stopper 134 is slidably matched with the second hole section 142. The cross-sectional area of ​​the second hole section 142 is larger than the cross-sectional area of ​​the first hole section 141. In the process of the mounting platform 3 moving up and down and driving the buffer seat 13 through the supporting connecting rod 313, the slider 133 passes through the first hole section 141 and slides in the second hole section 142, and the stopper 134 is clamped on the inner side wall of the first hole section 141 to maintain the connection between the buffer seat 13 and the base 1. Since the cross-sectional area of ​​the first hole section 141 is small, the stopper 134 cannot pass through the first hole section 141 and slide outward, thereby realizing the connection and fixation of the buffer seat 13 and the base 1. This design transmits the non-vertical axis force on the mounting platform 3 to the buffer seat 13 and the matching part 14 through the supporting connecting rod 313. The cooperation between the slider 133, the limit block 134 and the matching part 14 balances the transmitted force and improves the stability of the mounting platform 3 during the lifting process.

[0035] Please refer to Figures 1 to 4 In this embodiment, an electronic display screen 332 is provided on the signboard 33. Through the electronic display screen 332, the staff can easily update the display content. Whether it is text, pictures or videos, they can be quickly displayed on the electronic display screen 332, which greatly improves the update speed and efficiency of information.
