Description

Technical Field

[0001] The utility model relates to the technical field of advertisement placement equipment, in particular to a card cloth light box body structure. Background Art

[0002] In the field of modern advertising display, the Kabu light box is widely used in various indoor and outdoor occasions due to its high clarity, convenient installation, and easy image replacement. Especially in outdoor advertising display, the Kabu light box has become the first choice for merchants' publicity applications due to its unique advantages, such as waterproof, UV protection, strong weather resistance, and high cost performance.

[0003] Deficiencies of existing technology:

[0004] The existing outdoor card cloth light box is mainly composed of a light box frame, a back plate, an LED light bar and an advertising screen. Among them, the light box frame is usually made of aluminum alloy or stainless steel to ensure that it is light and durable, and the back plate is mostly made of organic glass or PC sheet, which has good light transmittance and durability. However, during outdoor use, especially in an environment with strong wind, the card cloth light box of this structure has obvious defects. Because its structural design lacks effective resistance to wind force, the light box is prone to shaking or even falling in the face of strong winds, and has poor stability, which brings great inconvenience and safety hazards to advertising display, especially when the area of ​​the advertising cloth is large, the force area is also large, and the impact of the wind is greater. Some merchants will rotate the angle of the card cloth light box on windy days to keep the advertising cloth parallel to the wind direction and reduce the force area, so as to achieve the purpose of improving wind resistance. However, due to the change of the advertising display angle, the display effect will inevitably be affected. Therefore, the existing card cloth light box structure has been difficult to meet the actual use needs of current users. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0031] See also Figure 1-4 As shown, the utility model provides a technical solution for the box structure of a card cloth light box: a card cloth light box box structure, including a base 1, a cloth frame 2 for installing an advertising screen is installed on the upper end surface of the base 1, a counterweight mechanism 3 and a labor-saving component 4 are installed on the lower end surface of the internal cavity of the base 1, and a controller 5 is also installed on the lower end surface of the internal cavity of the base 1. The counterweight mechanism 3 includes a mounting groove 301, a mounting shaft 304, a connecting rod 306 and a wind speed and direction sensor 308. The mounting groove 301 is opened on the lower end surface of the internal cavity of the base 1, and a motor 302 is horizontally installed in the mounting groove 301 through a mounting bracket, and the output end of the motor 302 is connected to a first bevel gear 303. The mounting shaft 304 is vertically centered and installed in the mounting groove 301, and the two ends of the mounting shaft 304 are respectively rotatably connected to the upper and lower end surfaces of the base 1, and the lower end of the mounting shaft 304 is located in the mounting groove 301 and fixedly installed with a second bevel gear 305 meshing with the first bevel gear 303 for driving the rotation of the mounting shaft 304. One end of the connecting rod 306 is on the installation shaft 304, and the other end of the connecting rod 306 is connected to a counterweight 307. A wind speed and direction sensor 308 is installed at the upper end of the cloth frame 2. When the card cloth light box needs to be used outdoors, the base 1 is first placed on the ground, and then the advertisement on the cloth frame 2 is facing the display direction. During the outdoor display process, if the wind speed and direction sensor 308 detects that there is wind blowing, it will send an electrical signal to the controller 5. After the controller 5 determines the wind direction, it controls the motor 302 to start and rotate a certain number of circles. The motor 302 drives the second bevel gear 305 to rotate through the first bevel gear 303, and the second bevel gear 305 then drives the installation shaft 304 and the connecting rod 306 to rotate a certain angle to adjust the position of the counterweight 307. The adjusted connecting rod 306 and the counterweight 307 should face the direction of the wind. At this time, the overall center of gravity of the card cloth light box is also biased towards the direction of the wind, and the stability is improved. Through the counterweight mechanism 3, a counterweight is added to the base 1 of the Kabu light box, and the position of the counterweight can be adjusted according to the wind direction. Without adjusting the angle of the cloth frame 2 and ensuring the display effect, the stability and wind resistance of the Kabu light box outdoors are improved, which is more in line with the current application requirements of the Kabu light box in outdoor display scenes.

[0032] The labor-saving component 4 includes a permanent magnet block 401 and a ball 403. The permanent magnet block 401 is installed at the lower end of the counterweight block 307, and an electromagnet ring 402 matching the permanent magnet block 401 is installed on the lower end surface of the internal cavity of the base 1. When the controller 5 determines that the position of the counterweight block 307 needs to be adjusted, the electromagnet ring 402 is first controlled to be energized, and the electromagnet ring 402 generates a repulsive force on the permanent magnet block 401, thereby generating an upward thrust on the counterweight block 307, so that the friction force received by the counterweight block 307 during the movement is reduced as a whole. The ball 403 is installed in the spherical groove at the lower end of the counterweight block 307, and the ball 403 converts the sliding friction between the counterweight block 307 and the lower end surface of the base 1 into rolling friction. Through the labor-saving component 4, the friction between the lower end surface of the counterweight block 307 and the base 1 is reduced, the torque demand for the motor 302 is reduced, the smoothness of the counterweight block 307 during movement is improved, and the service life of the motor 302 is also improved.

[0033] The controller 5 is electrically connected to the motor 302 , the wind speed and direction sensor 308 , and the electromagnet ring 402 , respectively. The controller 5 makes a judgment based on the signal transmitted by the wind speed and direction sensor 308 and issues a command to control the motor 302 and the electromagnet ring 402 to energize and operate.

[0034] The transmission ratio between the first bevel gear 303 and the second bevel gear 305 is greater than 1. By setting the transmission ratio, the first bevel gear 303 can drive the second bevel gear 305 to rotate more effortlessly, thereby reducing the torque requirement for the motor 302 .

[0035] A plurality of universal wheels 6 are mounted on the lower end surface of the base 1 , and the universal wheels 6 are more convenient for the flexible movement of the cab light box outdoors.

[0036] The installation direction of the motor 302 is parallel to the display direction of the cloth rack 2. The parallel setting makes it easier for the staff to observe the positions of the connecting rod 306 and the counterweight block 307 later to calibrate the motor 302.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
