[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-5 An outdoor floor-standing advertising light box comprises a base 1 and a light box body 2 mounted on the base 1, a plurality of LED lights 17 are arranged in the light box body 2, a box cover 3 is hingedly mounted on the front of the light box body 2, a visual window is opened on the box cover 3, rollers 4 are symmetrically arranged on the upper and lower sides of the light box, a fixing mechanism for fixing an advertising cloth is arranged on the rollers 4, one of the rollers 4 is rotatably arranged, and a knob 5 is fixedly installed on the end of the roller 4 that passes through the outside of the light box body 2, and the other roller 4 is movably arranged through an elastic component. By setting the rollers 4, the fixing mechanism and the elastic component, when installing the advertising cloth, it is only necessary to install the two ends of the advertising cloth on the two rollers 4 through the fixing mechanism. , and then turn the knob 5 on the side of the light box body 2. When the knob 5 drives one of the rollers 4 to rotate, the advertising cloth can be tightened between the two rollers 4, and the installation of the advertising cloth can be achieved. The setting of the elastic component, when the advertising cloth is squeezed by an unexpected external force, one of the rollers 4 can move toward the other roller 4 under the action of the elastic component, so as to avoid the advertising cloth from being torn. Moreover, after the elastic component drives the roller 4 to reset, the advertising cloth can be tightened again. Compared with the prior art of fixing the advertising cloth with a seal, it is not only convenient to disassemble and replace the advertising cloth, but also avoids the wrinkles or tears caused by the unexpected external force squeezing the advertising cloth.

[0021] Among them, the fixing mechanism includes a clamping plate 6 and a pair of fastening screws 7 symmetrically installed on the clamping plate 6. The roller shaft 4 is provided with a threaded hole adapted to the fastening screws 7. Specifically, when fixing the advertising cloth, it is only necessary to pass the end of the advertising cloth between the clamping plate 6 and the roller shaft 4, and then turn the screws on the clamping plate 6 to quickly fix one end of the advertising cloth. It has the advantages of simple structure and convenient operation.

[0022] Preferably, a non-slip rubber strip 8 is installed on the side of the pressing plate 6 close to the roller 4. The setting of the non-slip rubber strip 8 increases the friction resistance between the pressing plate 6 and the advertising cloth, effectively preventing the advertising cloth from slipping between the roller 4 and the pressing plate 6 when the advertising cloth is tightened or squeezed by unexpected external force.

[0023] Among them, the elastic component includes a fixing plate 9 symmetrically fixedly installed at both ends of the roller shaft 4 and a pair of guide rods 10 movably installed on the fixing plate 9, one end of the guide rod 10 is fixedly connected to the top surface of the light box body 2, and the other end is fixedly installed with a baffle 11. The guide rod 10 is located between the fixing plate 9 and the baffle 11, and a spring 12 is also sleeved on the rod body. Specifically, when the advertising cloth is squeezed by unexpected external force, the setting of the two guide rods 10 on one side can enable the roller shaft 4 installed between the two fixing plates 9 to move vertically downward or upward. When the roller shaft 4 is reset, the advertising cloth can be tightened in the vertical direction.

[0024] In addition, after the advertising cloth is tightened by rotating the lever 16, in order to prevent the roller 4 from reversing, a braking unit for limiting the unidirectional rotation of the roller 4 is also installed on the light box body 2 in the present application, and the braking unit includes a hollow disk 13 fixedly installed on the side of the light box body 2, a ratchet 14 rotatably installed in the hollow disk 13, and a pawl 15 adapted to the ratchet 14, the ratchet 14 is coaxially fixedly connected to the roller 4, and a lever 16 connected to the pawl 15 is also installed outside the hollow disk 13. Specifically, the setting of the ratchet 14 and the pawl 15 makes the roller 4 can only rotate in one direction and unidirectionally wind one end of the advertising cloth. After the advertising cloth is tightened, the roller 4 cannot reverse in the opposite direction. If you want to rotate the roller 4 in the opposite direction, you need to rotate the lever 16 on the hollow disk 13 in advance. After the pawl 15 is separated from the ratchet 14, the knob 5 can be smoothly turned to reverse the roller 4.
