[0015] Example

[0016] like Figures 1 to 8 As shown, this utility model proposes a project image signboard that can be quickly assembled and disassembled, including a base 1. The top surface of the base 1 has a mounting groove, and two pin slots are provided on both the left and right sides of the mounting groove. A vertical plate 2 is slidably mounted inside the mounting groove. A T-shaped groove is provided inside the vertical plate 2. A knob 3 is rotatably mounted on the front side of the vertical plate 2, and a worm gear 4 is mounted on the rear side of the knob 3. The knob 3 and the worm gear 4 are fixedly connected, and the worm gear 4 is rotatably connected to the vertical plate 2. The rear end of the worm gear 4 extends through into the interior of the T-shaped groove. The inner walls of the left and right sides of the T-shaped groove are connected... The system is equipped with a bidirectional lead screw 5, and a worm gear 6 is provided on the outer ring of the middle end of the bidirectional lead screw 5. The outer ring of the bidirectional lead screw 5 and the inner ring of the worm gear 6 are fixedly connected. The worm 4 and the worm gear 6 are meshed. When the knob 3 is turned, the worm 4 can be driven to rotate. The rotation of the worm 4 can drive the worm gear 6 to rotate, which in turn drives the bidirectional lead screw 5 to rotate. Both ends of the bidirectional lead screw 5 are threadedly connected to threaded blocks 7. The outer wall of the threaded block 7 is in contact with the inner walls of the front and rear sides of the T-slot and is slidably connected, which facilitates the guidance and limitation of the running trajectory of the threaded block 7. Two pins 8 are provided on the opposite sides of the two threaded blocks 7. The threaded blocks 7 and the pins 8 are fixedly connected. Through holes are provided on both sides of the upright plate 2 corresponding to the position of each pin 8. The pins 8 are slidably connected to the through holes, facilitating their movement. The pins 8 are slidably connected to their corresponding pin slots, allowing for quick disassembly and assembly of the base 1 and the upright plate 2 by inserting the pins 8 into the slots. A rectangular groove is provided inside the upright plate 2. A knob 9 is rotatably mounted on the rear side of the upright plate 2. A rotating rod 10 is provided on the front side, and a knob 9 is fixedly connected to the rotating rod 10. The front end of the rotating rod 10 extends through into the interior of the rectangular groove and is provided with a drive wheel 11. The rotating rod 10 is fixedly connected to the drive wheel 11. Two rotating rods 12 are rotatably arranged between the inner walls of the front and rear sides of the rectangular groove. Each rotating rod 12 has a driven wheel 13 on the outer ring of its rear end. The rotating rod 12 is fixedly connected to the driven wheel 13. The drive wheel 11 is meshed with both driven wheels 13 to facilitate transmission. Each rotating rod 12 has a gear 14 on its front outer ring, and the rotating rod 12 is fixedly connected to the gear 14. Two sets of racks 15 are slidably arranged on the front inner wall of the T-slot, and each set of racks 15 meshes with a corresponding gear 14 for easy transmission. A trapezoidal groove is opened on the front inner wall of the T-slot corresponding to the position of each rack 15. A trapezoidal strip 18 is provided on the front side of each rack 15, and the front side of the rack 15 is fixedly connected to the rear side of the trapezoidal strip 18. The trapezoidal strip 18 is slidably connected to the trapezoidal groove. The trapezoidal groove can guide and limit the trapezoidal strip 18, thereby guiding and limiting the running trajectory of the rack 15. 15 always maintains a straight running state. Two racks 15 in the same group are provided with insert rods 16 on the opposite sides. The racks 15 and insert rods 16 are fixedly connected. A sign body 17 is slidably provided on the front side of the upright plate 2. An assembly groove is opened on the rear side of the sign body 17. Slots are opened on the left and right sides of the assembly groove corresponding to the position of each insert rod 16. The insert rods 16 are slidably connected to the slots. The insert rods 16 are installed into the slots to facilitate quick disassembly and assembly of the upright plate 2 and the sign body 17. Through slots are opened on the left and right sides of the upright plate 2 corresponding to the position of each insert rod 16. The insert rods 16 are slidably connected to the through slots to facilitate the movement of the insert rods 16.

[0017] In this embodiment, when using this device, to assemble the base 1 and the upright plate 2, the upright plate 2 must first be installed into the mounting groove on the top surface of the base 1. Then, rotate knob 3. The output end of knob 3 drives the worm gear 4 to rotate. The rotation of the worm gear 4 drives the worm wheel 6 to rotate. The rotation of the worm wheel 6 drives the double-acting screw 5 to rotate. The rotation of the double-acting screw 5 drives the two threaded blocks 7 to move away from each other, thereby moving the pins 8 on the left and right sides into the pin slots, thus completing the assembly of the base 1 and the upright plate 2. Then, the upright plate 2 is installed into the assembly groove on the rear side of the sign body 17. Then, rotate knob 29. The output end of knob 29 drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the driving wheel 11 to rotate. The rotation of the driving wheel 11 drives the two driven wheels 13 to rotate. The rotation of the driven wheels 13 drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the two gears 14 to rotate. The rotation of the gears 14 drives the two racks 15 meshed with the gears 14 to move closer or further apart, so that the insertion rod 16 can be installed into the corresponding slot, thereby completing the assembly of the upright plate 2 and the sign body 17.
