[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an outdoor energy-saving display screen includes a display screen body 1 and multiple support columns 2. The display screen body 1 is disposed between the support columns 2. A positioning channel is vertically provided on the support columns 2. Positioning shells 17 are fitted on both ends of the display screen body 1. Multiple positioning plates 5 are installed on the opposite end faces of the positioning shells 17. The positioning plates 5 are all inserted into the positioning channels. A clearance groove 16 is provided on one end of the positioning plate 5 located inside the positioning channel. An adjustment seat 6 is provided in each positioning channel. A lifting mechanism that drives the display screen body 1 to move up and down is installed on the adjustment seat 6. An operating mechanism that drives the positioning shells 17 to move is also installed on the adjustment seat 6. A cleaning mechanism and a base plate 3 are installed between the support columns 2.

[0022] In this embodiment, the lifting mechanism includes a motor, a lead screw 18, a fixing plate 9, and a first bearing. The fixing plate 9 is installed at the highest point of the positioning channel, and the first bearing is embedded in the center of the fixing plate 9. The end of the support column 2 without the positioning channel has an installation cavity. The motor is installed in the installation cavity, and the motor shaft extends into the positioning channel. The lead screw 18 is installed in each motor through a coupling. The adjusting seat 6 has a vertical lead screw hole. The lead screw 18 passes through the clearance groove 16 and is threadedly connected to the lead screw hole. The other end of the lead screw 18 is installed in the inner ring of the first bearing.

[0023] In this embodiment, the operating mechanism includes a screw 14, a gripping rod 12, a positioning rod 13, and a second bearing. The second bearing is embedded in the outer end face of the positioning housing 17. The adjusting seat 6 is provided with a screw hole that communicates with the inner ring of the second bearing. The screw 14 is threaded into the screw hole. One end of the screw 14 is installed in the inner ring of the second bearing, and the other end of the screw 14 is fixedly connected to the gripping rod 12. The adjusting seat 6 is provided with a positioning hole on the side of the screw hole. One end of the positioning rod 13 passes through the positioning hole and is installed on the positioning housing 17.

[0024] In this embodiment, the cleaning mechanism includes a crossbar 10 and a rubber strip 11. The two ends of the crossbar 10 are mounted on the support column 2. The crossbar 10 protrudes to one side of the display screen body 1 to form a fixing part. The rubber strip 11 is mounted on the fixing part, and the inner side of the rubber strip 11 is flush with the screen on the display screen body 1.

[0025] In this embodiment, the base plate 3 is disposed at the bottom of the display screen body 1, and the two ends of the base plate 3 are mounted on the support column 2. The middle part of the base plate 3 protrudes upward to form a placement part 4, and the display screen body 1 is placed on the placement part 4. The bottom surface of the base plate 3 is in contact with the ground.

[0026] In this embodiment, both sides of the positioning channel are provided with vertical grooves 19, and both ends of the adjusting seat 6 protrude to form sliders 15. The sliders 15 are slidably disposed in the grooves 19. The cross sections of the sliders 15 and the grooves 19 are both set in a "T" shape. The adjusting seat can be positioned by the sliders and the grooves, so that the positioning seat can only move up and down along the positioning groove.

[0027] In this embodiment, the end of the support column 2 away from the positioning channel is narrowed inward and multiple insert plates 7 are installed in a ring structure. Insert rods 8 are vertically installed on the bottom surface of the support column 2. The insert rods 8 and insert plates 7 at the bottom of the support column 2 are used to firmly install the entire device on the ground. The insert plates increase the contact area with the ground.

[0028] In this embodiment, the width of the positioning plate 5 is matched with the width of the positioning channel, which increases stability and avoids swaying in the positioning channel.

[0029] In this embodiment, a clearance space is formed between the opposite end face of the positioning shell 17 and the adjustment seat 6 to allow the positioning shell 17 to move outward, so that the positioning shell can move outward smoothly until it detaches from the display screen body.

[0030] In this embodiment, the clearance grooves 16 are all U-shaped structures. A gap is formed between the clearance grooves 16 and the lead screw 18 to allow the positioning shell 17 to move outward. The positioning plate increases the positioning effect of the positioning shell, enabling the positioning shell to move stably in and out of the positioning channel. The clearance grooves avoid affecting the rotation of the lead screw.

[0031] Working principle: When installing the display screen body 1, first place the display screen body 1 on the placement part 4 of the base plate 3. The placement part can lift the display screen body so that the two ends of the display screen body do not contact the base plate. Then, move the positioning shell 17 towards the display screen body 1 through the operating mechanism. When facing left, rotate the handle 12 to drive the screw 14 to rotate. Since the screw 14 is threadedly connected to the screw hole on the adjusting seat 6, and one end of the screw 14 is connected to the positioning shell 17 through the second bearing, the rotation of the screw 14 will push the positioning shell 17 to move inward, so that the positioning shell 17 is fitted onto both ends of the display screen body 1.

[0032] During this process, the positioning rod 13 and the positioning plate play a guiding role to ensure that the positioning shell 17 moves smoothly. The positioning plate 5 is inserted into the positioning channel of the support column 2, and the clearance groove 16 provides clearance space for the lead screw 18.

[0033] When the height of the display body 1 needs to be adjusted, the motor of the lifting mechanism is started. The motor drives the lead screw 18 to rotate. Since the adjustment seat 6 is threadedly connected to the lead screw 18 through the lead screw hole, and the sliders 15 on both sides of the adjustment seat 6 are limited to slide in the slide groove 19, the rotation of the lead screw 18 will drive the adjustment seat 6 to move up and down along the positioning channel.

[0034] The adjustment seat 6 is connected to the positioning shell 17 through the operating mechanism, thereby driving the display screen body 1 to rise and fall synchronously to achieve height adjustment. The top of the lead screw 18 is installed in the first bearing of the fixed plate 9 to ensure smooth rotation.

[0035] During the lifting and lowering process of the display body 1, when passing the cleaning mechanism, the rubber strip 11 on the crossbar 10 contacts the screen surface of the display body 1. By moving relative to the screen, the automatic cleaning function is achieved. Generally, the display body is located above the crossbar and does not contact the crossbar, so the crossbar will not affect the use of the display body.

[0036] During disassembly, reverse the lever 12 to move the positioning shell 17 outwards and remove it from both ends of the display body 1, so that the display body 1 can be removed from the placement part 4. The entire disassembly and assembly process does not require the use of bolts or climbing, making it simple and efficient.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
