The transmission bevel gear 13 is rotated to realize the rotation of the transmission rod 12, and then the rotation of the worm 17 is realized. The worm 17 drives the worm wheel 16 to rotate, and the rotation of the rotating shaft 11 is realized, and then the rotation of the winding drum 15 is realized. By changing the direction of the transmission bevel gear 13, the direction of the winding drum 15 is adjusted. A traction rope 9 is wound around the winding drum 15. One end of the traction rope 9 extends outward through the lifting frame 5 and is connected to a counterweight block 10. The counterweight block 10 can be set when the winding drum 15 rotates to release the traction rope 9, and the traction rope 9 can be automatically dropped by the counterweight block 10. The counterweight block 10 is tied to the corner of the advertising cloth. When the winding drum 15 reverses and winds the traction rope 9, the advertising cloth is pulled up accordingly.

[0024] Further discussion: Two hydraulic rods 2 for driving the lifting frame 5 to rise and fall are symmetrically fixedly connected to the bottom of the advertising frame 1, a sealing cover 3 is fixedly connected to the top edge of the lifting frame 5, and two mounting rails 4 for mounting on the wall are symmetrically fixedly connected to the outer wall of the advertising frame 1. The mounting rails 4 pass through the sides of the sealing cover 3, and the lifting frame 5 is moved in and out of the advertising frame 1 by means of the extension and retraction of the hydraulic rods 2. After the lifting frame 5 enters the advertising frame 1, the sealing cover 3 on its surface can seal the top edge of the advertising frame 1, the mounting rails 4 are fixed to the wall, and the advertising frame 1 is fixed to the bottom edge of the mounting rails 4. The sliding connection between the mounting rails 4 and the sealing cover 3 is used to ensure that the lifting frame 5 will not tilt during the lifting process.

[0025] Further discussion: the two transmission bevel gears 13 are located on the same side of the lifting frame 5 and are symmetrically distributed. The lifting frame 5 is hollowed out between the two transmission bevel gears 13, and a driving bevel gear 14 for meshing with the transmission bevel gear 13 is provided at the hollow part. A motor 7 for driving the driving bevel gear 14 to rotate is provided on the front of the lifting frame 5. An electric push rod 8 for driving the motor 7 to slide is fixedly connected to the front of the lifting frame 5. The output shaft of the motor 7 is slidably connected to the hollow part of the lifting frame 5. A cushion block 6 is fixedly connected to the front of the lifting frame 5. The end face of the cushion block 6 is flush with the casing of the motor 7. The driving bevel gear 14 on the motor 7 and its main shaft is lifted and lowered by telescoping the electric push rod 8, so that the driving bevel gear 14 can be meshed with the transmission bevel gears 13 at the upper and lower positions. Therefore, the driving bevel gear 14 is driven to rotate by the motor 7 to realize the rotation of the meshing transmission bevel gear 13, which can drive the corresponding transmission rod 12 to rotate, and the operation of the upper or lower dragging mechanism can be realized.

[0026] Working principle: fix the installation track 4 on the wall. When replacing the advertising cloth, the hydraulic rod 2 extends to lift the lifting frame 5 out of the advertising outer frame 1, and then the electric push rod 8 is extended to realize the rise of the driving bevel gear 14 on the motor 7 and its main shaft, so that the driving bevel gear 14 can be meshed with the transmission bevel gear 13 at the upper position. Therefore, the driving bevel gear 14 is driven by the motor 7 to rotate, and the meshing transmission bevel gear 13 is rotated, which can drive the upper transmission rod 12 to rotate, so that the upper dragging mechanism can be operated and the upper traction rope 9 can be released. After releasing a certain length, the traction rope 9 is tied to the top edge of the advertising cloth, and then the electric push rod 8 is used. By manually lowering the motor 7 and the driving bevel gear 14 on its main shaft, the driving bevel gear 14 can be meshed with the transmission bevel gear 13 at the lower position. Therefore, the driving bevel gear 14 is driven by the motor 7 to rotate, and the meshing transmission bevel gear 13 is rotated, which can drive the transmission rod 12 below to rotate, so that the dragging mechanism below can be operated and the traction rope 9 below can be released. After a certain length is released, the traction rope 9 is tied to the bottom edge of the advertising cloth, and then the traction rope 9 is rolled up by the dragging mechanism, so that the advertising cloth can be lifted and unfolded and located on the front of the lifting frame 5, and then the hydraulic rod 2 is contracted to re-store the lifting frame 5 into the advertising outer frame 1.

[0027] The wiring diagram of the hydraulic rod 2, motor 7 and electric push rod 8 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the hydraulic rod 2, motor 7 and electric push rod 8 are no longer explained in detail.
