[0016] Example: See Figure 1 - Figure 4 The utility model provides a technical solution: a sign display structure that is easy to replace, comprising: a base 1; a sliding door 2, the outer wall of the sliding door 2 is rotatably connected to the inner wall of the base 1; a pedal device 3, the outer wall of the pedal device 3 is slidably connected to the inner wall of the middle part of the base 1; a locking device 4, the outer wall of the locking device 4 is fixedly connected to the two sides of the base 1.

[0017] The pedal device 3 includes a movable block 31, a positioning groove 32 is provided in the wall of the movable block 31, a positioning shaft 33 is fixedly connected to the inner wall of the bottom of the movable block 31, a V-shaped rod 34 is rotatably connected to the outer wall of the positioning shaft 33, a sliding rod 35 is rotatably connected to the middle part of the V-shaped rod 34, the outer wall of the sliding rod 35 is slidably connected to a limit frame 37, a compression spring 36 is fixedly connected to the inner wall of the limit frame 37, one end of the compression spring 36 away from the inner wall of the limit frame 37 is fixedly connected to the outer wall of the sliding rod 35, the bottom of the limit frame 37 is fixedly connected to the bottom of the inner wall of the base 1, the inner wall of the base 1 is slidably connected to the side wall of the movable block 31, the user supports the sign with both hands, one foot supports the body, and the other foot steps on the top protrusion of the V-shaped rod 34 away from the inside of the base 1. The top protrusion of the V-shaped rod 34 falls and gradually approaches the bottom of the inner wall of the base 1, and the bent part of the V-shaped rod 34 drives the sliding rod 35 to move. The middle section of the sliding rod 35 is cylindrical and the two ends are block-shaped, so the moving sliding rod 35 can squeeze the compression spring 36 while moving in the limit frame 37, and the other end of the V-shaped rod 34 drives the positioning shaft 33 to move, so that the movable block 31 moves upward until the movable block 31 is blocked by the protrusion at the top of the base 1. At this time, the top of the movable block 31 is flush with the top of the base 1. The staff can place the sign on the plane on the base 1 and easily place the sign into the positioning groove 32. When disassembling, they only need to step on the foot pedal 3 to lift the sign to take it out, which is convenient for the staff to install and disassemble.

[0018] The locking device 4 includes a fixed plate 41, the outer wall of the fixed plate 41 is fixedly connected to a bidirectional servo motor 42, the output end of the bidirectional servo motor 42 is fixedly connected to a driving screw 43, the outer wall of the driving screw 43 is threadedly connected to a side clamping plate 44, a rotating shaft 45 is arranged outside the side clamping plate 44, the outer wall of the rotating shaft 45 is threadedly connected to an upper clamping plate 47 through a thread groove 46, and the thread groove 46 is opened in the wall of the rotating shaft 45, the outer wall of the side clamping plate 44 and the outer wall of the upper clamping plate 47 are both slidably connected to the outer wall of the fixed plate 41, the outer wall of the rotating shaft 45 is rotatably connected to the inner wall of the fixed plate 41, the outer wall of the fixed plate 41 is fixedly connected to the outer wall of the base 1, and the outer wall of the fixed plate 41 is slidably connected to the outer wall of the movable block 31. When the sign needs When locked, the bidirectional servo motor 42 is controlled to rotate, thereby forcing the driving screws 43 at both ends to rotate. Since the threads of the driving screws 43 at both ends have opposite rotation directions, the side clamps 44 have the ability to approach and move away from each other, and move along the outer wall of the fixed plate 41 under the restriction of the fixed plate 41, so that the display structure has the ability to clamp the sign from both sides, and the top protrusion of the rotating shaft 45 is rotated, so that the rotating shaft 45 rotates. Under the restriction of the protrusion of the fixed plate 41, the rotating shaft 45 is difficult to move axially. At this time, the rotating shaft 45 will drive the upper clamp 47 to move upward or downward through the thread groove 46, so that the display structure has the ability to limit the sign from above, and cooperate with the positioning groove 32 to clamp the sign.

[0019] Working principle:

[0020] When in use, a pedal device 3 is provided to install the sign. Before installation, the user opens 2 the sliding door on the base 1 to expose the pedal device 3 inside the base 1. The user supports the sign with both hands, supports the body with one foot, and steps on the top protrusion of the V-shaped rod 34 away from the inside of the base 1 with the other foot. At this time, the top protrusion of the V-shaped rod 34 falls and gradually approaches the bottom of the inner wall of the base 1, and the bending part of the V-shaped rod 34 drives the sliding rod 35 to move. The middle section of the sliding rod 35 is cylindrical and the two ends are block-shaped, so the moving sliding rod 35 can squeeze the compression spring 36 while moving in the limit frame 37. In this process, the compression spring 36 is compressed to generate elastic force, and the other end of the V-shaped rod 34 drives the positioning shaft 33 moves, causing the movable block 31 to move upward until the movable block 31 is blocked by the protrusion on the top of the base 1. At this time, the top of the movable block 31 is flush with the top of the base 1, and the staff can place the sign on the plane on the base 1 and easily place the sign into the positioning groove 32. At this time, the staff only needs to slowly apply force to the pedal foot, and the compression spring 36 pushes the sliding rod 35 to move, so that the pedal device 3 as a whole moves in the opposite direction along the above process, so that the sign slowly enters between the base 1 and the fixed plate 41. Finally, under the limit of the base 1, the movable block 31 and the fixed plate 41, the sign is fixed. When disassembling, it is only necessary to step on the pedal device 3, lift the sign and take it out, which is convenient for the staff to install and disassemble.

[0021] The locking device 4 is provided to further fix the auxiliary sign, so that the sign is not easy to shake. At the same time, the locking device 4 enables the display structure to be suitable for signs of different lengths and widths. When the sign needs to be locked, the bidirectional servo motor 42 is controlled to rotate, thereby forcing the driving screws 43 at both ends to rotate. Since the threads of the driving screws 43 at both ends rotate in opposite directions, the side clamping plates 44 have the ability to approach and move away from each other, and move along the outer wall of the fixing plate 41 under the restriction of the fixing plate 41, so that the display structure has the ability to clamp the sign from both sides, and the user rotates the shaft at the same time. The top of 45 is raised, so that the shaft 45 rotates. Under the restriction of the raised fixed plate 41, the shaft 45 is difficult to move axially. At this time, the rotating shaft 45 will drive the upper clamping plate 47 to move upward or downward through the threaded groove 46, so that the display structure has the ability to limit the sign from above, and cooperate with the positioning groove 32 to clamp the sign, so that the locking device 4 further fixes the sign to prevent the sign from shaking. At the same time, the adjustable clamping range also allows the display structure to adapt to signs of different lengths and widths, and even if the sign has errors in length and width, it can be clamped and fixed.
