[0021] Reference Figure 1-3 As shown, this poolside lifting advertising screen includes a housing 1, a back frame 2 movably connected to the housing 1, and a display screen 3 connected to the front of the back frame 2. A multi-segmented support tube 4 is vertically arranged inside the housing 1. The support tube 4 is a hollow quadrangular prism, and the number of segments of the support tube 4 can be selected according to actual needs. As shown in the figure, the support tube 4 has a three-segment structure. The back frame 2 is connected to the support tube 4, and a mounting groove is provided at the edge of the pool. The housing 1 is installed in the mounting groove. The height of the mounting groove can be less than the depth of the mounting groove, allowing the housing to be completely accommodated within it. In this case, a movable cover is provided at the top of the mounting groove so that the advertising screen can be completely accommodated when not in use. Alternatively, the advertising screen can be partially embedded in the mounting groove, with the display screen 3 raised during use. Or, the main body of the housing 1 can be fixed to the upper side of the mounting groove, allowing the display screen 3 to provide a full-size image display even after it has fully descended. In order to lift the display screen 3 upward, a gear 5 and a rack 6 are provided between the back frame 2 and the housing 1. The rack 6 is set along the extension direction of the support tube 4, and the gear 5 is fixed to the output end of the motor 7.

[0022] The motor 7 drives the gear 5 to rotate, and the gear 5 meshes with the rack 6, converting the rotational motion of the motor 7 into linear motion, thereby driving the back frame 2 and the display screen 3 to rise and fall along the extension direction of the support tube 4, thereby achieving the purpose of raising and lowering to adjust the viewing angle and improve the visibility of the displayed advertisements and other information. At the same time, the support tube 4 has a multi-segment structure, providing vertical guidance and support to ensure smooth lifting. There are two main ways to fix the motor 7 and the rack 6. In the first way, when the motor 7 is fixed on the back frame 2, the rack 6 needs to be fixed inside the housing 1. Specifically, it can be connected to the outside of the support tube 4 or the side wall of the housing 1. After the motor 7 starts, the gear 5 rotates. Since the rack 6 is fixed, the gear 5 will roll along the rack 6, thereby pushing the back frame 2 to move and achieve lifting. In this way, the back frame 2 drives the motor 7 to move together, so the actual movement bears a large weight. This method is usually used for the purpose of protecting the motor 7.

[0023] Option 2 is the most common method. The rack 6 is fixed to the back frame 2, and the motor 7 is fixed to the support tube 4, usually on the outer side of the support tube 4. When the motor 7 rotates the gear 5, the gear 5 meshes with the rack 6, but the motor 7 is fixed. Therefore, the rotation of the gear 5 will directly drive the rack 6 and the back frame 2 to move, realizing lifting and lowering. In this option, the cable connection is more stable, and the overall stability and safety of the equipment are more guaranteed.

[0024] The gear 5 and rack 6 provide precise transmission, and the lifting height can be controlled by the motor 7, facilitating the display and concealment of the advertising screen and adapting to different scenario needs. The gear 5 and rack 6 mechanism is durable, with high transmission efficiency, suitable for frequent lifting operations, extending the equipment's lifespan. Especially when the display screen 3 does not need to be fully raised but remains suspended in mid-air, the rack 6 can also achieve stable stopping of the display screen 3 through the gear 5. The multi-segment support tube 4 provides rigid support, reducing swaying and ensuring a smooth and reliable lifting process. Suitable for wet environments near swimming pools, the housing 1 is embedded in the mounting groove by the poolside, taking up no extra space. Swimmers can see the advertisement while resting, avoiding distraction and ensuring swimmer safety while improving visibility.

[0025] This utility model achieves the raising and lowering of the advertising screen through the cooperation of gear 5 and rack 6, and maintains the stability of the raising and lowering through support tube 4. Combining the characteristics of the swimming pool environment, it is set in the installation groove by the pool so that swimmers can see it when they are resting, thus taking into account both stability and aesthetics.

[0026] The area of ​​the display screen 3 corresponds to the area of ​​one side of the cabinet 1. When the display screen 3 is not needed, the motor 7 will drive the back frame 2 to descend, so that the entire display screen 3 is completely retracted into the cabinet 1. If the area of ​​the display screen 3 is larger than the opening area on the side of the cabinet 1, it cannot be retracted into the cabinet 1. If it is much smaller than the side area of ​​the cabinet 1, a gap will be left in the cabinet 1 after the display screen 3 is lowered, which is not only unsightly but also poses a safety hazard. Therefore, the area of ​​the display screen 3 is designed to be equal to or very close to the side area of ​​the cabinet 1.

[0027] The top of the back frame 2 is fixedly connected to the top cover 8, which serves as the top plate of the cabinet 1. The rack 6 is fixedly connected to the back of the back frame 2. The top cover 8 is connected to the top of the back frame 2. The top cover 8, the display screen 3, and the cabinet 1 are combined to form a quadrangular prism. In the retracted state, the upper surface of the top cover 8 is flush with the surrounding ground, restoring the flatness of the pool edge and avoiding the risk of tripping, while maintaining aesthetics. The cabinet 1 itself is a cubic cavity with an open top. When the back frame 2 is lowered to the bottom, the top cover 8 closes the opening of the cabinet 1, so that the display screen 3, the cabinet 1, and the top cover 8 together form a relatively closed quadrangular prism, usually referring to a cuboid or cube. At the same time, the rack 6 is fixed to the back of the back frame 2. The entire transmission system is also hidden in the internal space formed by the back frame 2, the top cover 8, and the cabinet 1, thus being protected.

[0028] In addition, the back frame 2 uses multiple horizontal support rods and multiple vertical support rods that are fixedly connected. The multiple horizontal support rods and multiple vertical support rods are arranged in an alternating manner to achieve a more stable support effect.

[0029] The support tube 4 includes a main sleeve 41, with a secondary sleeve 42 movably connected inside the main sleeve 41. The main sleeve 41 is fitted over the secondary sleeve 42, and the top cover 8 is fixedly connected to the upper end of the innermost secondary sleeve 42. The core function of the support tube 4 is to guide the back frame 2 and the display screen 3 to rise and fall smoothly. The multi-segment design actually refers to the division into a main sleeve 41 and a secondary sleeve 42. Multiple secondary sleeves 42 can be designed and interlocked. This structure is designed to achieve a greater lifting stroke within a limited installation groove depth. The secondary sleeves 42 can extend from the main sleeve 41 to lift the top cover 8 and the back frame 2. The shapes of the main sleeve 41 and the secondary sleeve 42 do not need to be defined. For the convenience of motor 7 installation, a cubic shape is usually adopted, and the motor 7 is installed on the smooth side. To achieve the purpose of interlocking, the outer cross-sectional dimension of the secondary sleeve 42 is slightly smaller than the inner cross-sectional dimension of the main sleeve 41.

[0030] There are two gears 5 and two racks 6, which are symmetrically arranged on opposite sides of the support tube 4. When only one set of gears 5 and racks 6 is located on one side of the support tube 4, it will generate a torsional torque on the entire back frame 2 and support tube 4 when pushing the back frame 2 to rise and fall. This can easily cause the back frame 2 to jam, wear to increase, or the rise and fall to be unstable. Therefore, the two sets of gears 5 and racks 6 are symmetrically arranged on opposite sides of the support tube 4 to form a balanced couple, which cancels out the torsional torque generated when driving from one side, and ensures that the back frame 2 and support tube 4 only bear the vertical force during the entire rise and fall process.

[0031] The display screen 3 includes multiple interconnected display units 31, all of which are mounted on the back frame 2. The multiple display units 31 are spliced ​​together to form the display screen 3. Each display unit 31 is an independent and fully functional mini display screen 3. Visually, they are seamlessly combined to form a complete and large-sized image. Display screens 3 of any size can be manufactured without being limited by the manufacturing process of a single panel. Multiple small units can be transported separately, avoiding the huge risks and costs of transporting ultra-large, ultra-thin, and fragile overall screens.

[0032] The enclosure 1 also houses an electrical signal control box 11, which is connected to the side of the enclosure 1 furthest from the display screen 3. The electrical signal control box 11 is a dedicated enclosure 1 integrating a control unit, media player, and communication module. The control box has a built-in wireless receiver module for receiving commands from a remote control or the network. When a user sends a network command by pressing a button on the remote control, the control box receives these signals. The processor inside the electrical signal control box 11 interprets the "lift / lower" command and drives the power circuit of the connected motor 7, controlling the forward or reverse rotation of the motor 7, thereby raising or lowering the display screen 3. It can also store pre-made advertising videos and images internally and play them in a loop or according to instructions. The signal control box 11 can also be connected to an external network, allowing the display screen 3 to play video content from a network platform.

[0033] Hooks 12 are installed on opposite side plates of the housing 1. During initial installation, construction personnel can directly lift the entire device and place it into the installation slot by the pool, eliminating the need for complex manual handling and improving efficiency. When the device needs major repairs or replacement, there is no need for complicated disassembly in the narrow installation slot. Maintenance personnel can directly use lifting equipment to hook the hooks 12 and lift the entire housing 1 out of the installation slot and transport it to the maintenance workshop for operation, greatly reducing the difficulty and risk of on-site maintenance.

[0034] Gear 5 is a helical gear 5, and the teeth on rack 6 are inclined in one direction. The helix angle of helical gear 5 is the same as the inclination angle of the teeth on rack 6, and the direction of rotation is the same. When meshing, the teeth gradually start to contact from one end, smoothly transition to the entire tooth width, and then gradually disengage. The same helix angle and the same direction of rotation ensure that the contact surface can perfectly and smoothly transition during meshing. This continuous and progressive meshing process greatly reduces impact. At the same time, because the teeth are inclined, multiple teeth will be in meshing state at any given time, eliminating the inherent impact and noise of spur gear 5 transmission.

[0035] Furthermore, with more teeth sharing the load simultaneously, the force on each tooth is reduced, thus allowing for the transmission of greater torque and extending service life. When the motor 7 stops, the lateral clearance between the gear 5 and rack 6 is minimal, effectively preventing the display screen 3 from slightly wobbling up and down in a stationary state, resulting in more precise positioning. Overall, the downward pressure is guided by the inclined gear teeth into vertical and horizontal pressure. The horizontal pressure is directly guided to the housing 1 through the back frame 2 and the display screen 3, thus reducing the actual downward pressure received and extending service life.
