[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a traffic sign that is easy to replace, including a mounting frame 1, a sign body 2, a support frame 4 and a base frame 5. The sign body 2 is mounted on the inner surface of the mounting frame 1, and the sign body 2 is slidably matched with the sign body 2 through a support rod 11. The support frame 4 is fixedly mounted on the top of the base frame 5. The sign body 2 is provided with a guide frame 3 for guiding the sign body 2 for installation. A limit plate 14 is symmetrically arranged inside the mounting frame 1, and balls 13 are evenly distributed inside the limit plate 14.

[0021] A plurality of universal wheels 6 are symmetrically arranged at the bottom end of the base frame 5 , and the universal wheels 6 facilitate movement of the base frame 5 and the overall structure of the top end, thereby increasing the flexibility of the device.

[0022] The inner surface of the guide frame 3 is symmetrically provided with a brush roller 12 for assisting the vertical movement of the guide frame 3. The brush roller 12 can not only guide the installation of the sign body 2, but also clean the dust on the surface of the sign body 2 by rolling and rubbing against the sign body 2.

[0023] The outer surfaces of one end of the brush roller 12 and the ball 13 are located on the same vertical line, and the ends of the brush roller 12 and the ball 13 that are in contact with the sign body 2 have the same verticality, which can guide the installation of the sign body 2 and facilitate quick disassembly and assembly.

[0024] A lifting motor 7 is provided at the top of the support frame 4, and a screw rod 8 is connected to the output end of the lifting motor 7. The screw rod 8 is threadedly connected to the support rod 11. The support frame 4 is provided with a lifting motor 7 to drive the screw rod 8 and the support rod 11 to transmit the thread, so that the support rod 11 can move vertically on the inner surface of the support frame 4, which is convenient for adjusting the height of the sign body 2.

[0025] The support rod 11 is fixedly connected to the mounting frame 1, and a slide rod 9 is slidably connected inside the support rod 11. A guide rail 10 is provided at the connecting end of the support rod 11 and the support frame 4. The slide rod 9 and the guide rail 10 can not only guide the lifting and lowering of the support rod 11, but also increase the supporting force points of the support rod 11, thereby improving the lateral supporting force of the sign body 2.

[0026] Working principle: Before replacement, the height of the mounting frame 1 is adjusted downward, and the support frame 4 drives the lead screw 8 and the support rod 11 to transmit threaded transmission. The support rod 11 is lifted and lowered vertically along the outer surface of the slide rod 9 and the guide rail 10, thereby adjusting the height of the guide frame 3, and then the guide frame 3 to be replaced is taken out. The top of the guide frame 3 should protrude from the bottom surface of the guide frame 3, but not higher than the top surface of the guide frame 3. Since the interior of the guide frame 3 is a trapezoidal structure, it is convenient to take out the sign body 2 by hand-held clamping, and then put the replaced sign body 2 into the guide frame 3, slide along the inner wall of the guide frame 3, and fit with the brush roller 12, and roll along the outer surface of the ball 13 to reduce friction. Not only is the disassembly and assembly speed faster, but the disassembly and assembly movement can also be used to make the brush roller 12 clean the surface of the sign body 2, thereby increasing the practicality of the overall structure.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
