Description

Technical Field

[0001] This utility model relates to the technical field of signage, specifically to an LED sign with dimming function. Background Technology

[0002] Signage, as an important visual communication tool, is widely used in various fields, such as road traffic, construction, and public facilities. It uses text, graphics, colors, and shapes to provide users with warnings, guidance, and identification.

[0003] Signage can be classified according to different criteria. For example, based on function, it can be divided into directional signs, fixed signs, friendly reminder signs, and warning signs; based on installation method, it can be divided into floor-standing signs, hanging signs, wall-mounted signs, suspended signs, and embedded signs; based on application area, it can be divided into traffic signs, construction safety warning signs, and park signs.

[0004] The existing technology has the following problems: different signs are required in different environments, and construction workers need to select the appropriate installation location based on the sign and the appropriate support rod based on the sign. This requires construction workers to carry a variety of different support rods, which makes it inconvenient to carry the signs. At the same time, when replacing horizontal and vertical signs at the same location, workers need to completely disassemble the signs and reassemble the signs to be installed in order to achieve the replacement purpose. The required steps are relatively cumbersome, resulting in low replacement efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, an LED sign with dimming function is provided, which solves the problems of inconvenience in carrying and low replacement efficiency of current signs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An LED sign with dimming function includes a base plate. Two fixing tubes are fixedly installed on the upper surface of the base plate. The two fixing tubes are symmetrically distributed about the center line of the base plate. Each fixing tube has a support rod inside. A connecting rod is provided above the fixing tube. The connecting rod is fixedly connected to both support rods. A fixing rod is fixedly installed on the side of the connecting rod. A sliding groove is formed on the upper surface of the fixing rod. A sliding rod is provided inside the sliding groove. A fixing plate is fixedly installed at the upper end of the sliding rod. A housing is rotatably installed on the side of the fixing rod corresponding to the base plate. A limiting plate is fixedly installed on the side of the housing corresponding to the fixing plate. A limiting groove communicating with the sliding groove is formed through the side of the connecting rod corresponding to the limiting plate.

[0008] Preferably, a plurality of insertion slots are provided through the two fixed tubes on the side away from each other. The plurality of insertion slots are linearly distributed along the length of the fixed tubes. A sliding groove is provided inside the connecting rod corresponding to the insertion slot. A guide rod is fixedly installed on the inner wall of the sliding groove. A moving plate is provided inside the sliding groove corresponding to the guide rod. An insertion rod corresponding to the insertion slot is fixedly installed on the side of the moving plate away from the guide rod. A spring is sleeved on the outer surface of the guide rod. The two ends of the spring are fixedly connected to the inner wall of the sliding groove and the surface of the baffle, respectively.

[0009] Preferably, a circuit board is fixedly installed on the inner wall of the box, and a plurality of conical grooves are formed on the side of the circuit board away from the box. The plurality of conical grooves are evenly distributed about the surface of the circuit board. A baffle is rotatably installed on the inner wall of the box, and a placement groove is formed through the upper surface of the baffle. A placement plate is provided inside the placement groove.

[0010] Preferably, a rain shield is fixedly installed on the side of the box corresponding to the baffle.

[0011] Preferably, two hanging ears are fixedly installed on both the front and rear sides of the base plate, and the two hanging ears are symmetrically distributed about the center line of the base plate.

[0012] Preferably, the end of the insertion rod away from the baffle is provided with a dome.

[0013] Preferably, a buffer plate is fixedly installed on the upper surface of the connecting rod, and the buffer plate abuts against the box body.

[0014] Compared with the prior art, the advantages of this utility model are as follows: By setting up a sliding rod, a box body, and a fixing plate, the staff uses the placement plate to place the sign to be replaced into the box body, pulls the sliding rod to disengage the limiting plate from the limiting groove, rotates the box body to the appropriate position according to the sign to be installed, and then places the box body back in its original position, thereby completing the replacement of the sign. This reduces the steps required for sign replacement, and reduces the replacement time required for large-scale replacement, thereby improving replacement efficiency. Since the box body can be rotated to accommodate both horizontal and vertical signs, staff only need to carry the required number of installation devices in different environments, eliminating the need to carry multiple different support rods simultaneously, thus making it easier for staff to carry.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-6 As shown, an LED sign with dimming function includes a base plate 1. Two fixing tubes 2 are fixedly installed on the upper surface of the base plate 1. The two fixing tubes 2 are symmetrically distributed about the center line of the base plate 1. Each fixing tube 2 has a support rod 3 inside. A connecting rod 4 is provided above the fixing tube 2. The connecting rod 4 is fixedly connected to both support rods 3. A fixing rod 5 is fixedly installed on the side of the connecting rod 4. A sliding groove 6 is opened on the upper surface of the fixing rod 5. A sliding rod 7 is provided inside the sliding groove 6. A fixing plate 8 is fixedly installed at the upper end of the sliding rod 7. The corresponding fixing rod of the base plate 1... A box 11 is rotatably mounted on the side of the device. A limiting plate 9 is fixedly mounted on the side of the box 11 corresponding to the fixing plate 8. A limiting groove 10 communicating with the sliding groove 6 is opened through the side of the connecting rod 4 corresponding to the limiting plate 9. By pushing the box 11, the operator causes the box 11 to move the sliding rod 7 on the fixing plate 8, thereby causing the limiting plate 9 to disengage from the limiting groove 10. After rotating the box 11, the box 11 is slowly slid downward, so that another limiting plate 9 enters the limiting groove 10, thereby making the box 11 horizontal, so that the device can adapt to various different shapes of signs.

[0024] like Figure 5As shown, several insertion slots 12 are provided through the two fixed tubes 2 on their opposite sides. The insertion slots 12 are linearly distributed along the length of the fixed tubes 2. The connecting rod 4 corresponding to the insertion slot 12 has a sliding groove 13 inside. A guide rod 14 is fixedly installed on the inner wall of the sliding groove 13. A moving plate 15 is provided inside the sliding groove 13 corresponding to the guide rod 14. An insertion rod 16 corresponding to the insertion slot 12 is fixedly installed on the side of the moving plate 15 away from the guide rod 14. A spring 17 is sleeved on the outer surface of the guide rod 14. The two ends of the spring 17 are fixedly connected to the inner wall of the sliding groove 13 and the surface of the baffle 20, respectively. According to the height requirements of the billboard, the staff squeezes the insertion rod 16 to make the insertion rod 16 disengage from the insertion slot 12. Then, the connecting rod 4 is moved to a suitable position. The spring 17 pushes the insertion rod 16 on the baffle 20 into the insertion slot 12, thereby fixing the billboard in a suitable position.

[0025] like Figure 6 As shown, a circuit board 18 is fixedly installed on the inner wall of the housing 11. Several conical grooves 19 are opened on the side of the circuit board 18 away from the housing 11. The conical grooves 19 are evenly distributed on the surface of the circuit board 18. LED beads are placed in the conical grooves 19. A baffle 20 is rotatably installed on the inner wall of the housing 11. A placement groove 21 is opened through the upper surface of the baffle 20. A placement plate 22 is set inside the placement groove 21. When replacing the billboard, the staff pulls the placement plate 22 to make the placement plate 22 leave the placement groove 21. The staff replaces the billboard and places it in the placement plate 22. The LED directly illuminates the surface of the billboard. A sensor is set on the side of the housing. The sensor senses the external light intensity, so that the equipment controls the brightness of the LED beads in the conical grooves 19 according to the external sunlight intensity through the circuit board 18.

[0026] like Figure 1-4 As shown, a rain shield 23 is fixedly installed on the side of the housing 11 corresponding to the baffle 20. The rain shield 23 prevents rainwater from entering the housing 11 through the gap between the baffle 20 and the housing 11, thus preventing the advertisement from being contaminated. At the same time, it prevents rainwater from entering the circuit board 18, reducing the probability of equipment damage.

[0027] like Figure 1-4 As shown, two hanging ears 24 are fixedly installed on both the front and rear sides of the base plate 1. The two hanging ears 24 are symmetrically distributed about the center line of the base plate 1. After the equipment is moved to a suitable position, the staff inserts the bolts into the hanging ears 24 to fix the equipment in the suitable position.

[0028] like Figure 5As shown, the end of the insertion rod 16 away from the baffle 20 is provided with a dome 25. The design of the dome 25 reduces the friction and resistance between the insertion rod 16 and the edge of the insertion groove 12 when it is inserted into or pulled out of the insertion groove 12, making the operation smoother and avoiding jamming or damage caused by sharp edges. As the end of the insertion rod 16, the smooth shape of the dome 25 can effectively disperse and alleviate the impact force that may be generated during the insertion or pulling process, thereby protecting the insertion rod 16, the insertion groove 12 and the surrounding structure from damage and extending the service life of the sign.

[0029] like Figure 1-4 As shown, a buffer plate 26 is fixedly installed on the upper surface of the connecting rod 4. The buffer plate 26 abuts against the housing 11. The abutment between the buffer plate 26 and the housing 11 forms a protective barrier, preventing the housing 11 from directly contacting the connecting plate or other hard objects. This avoids wear or deformation of the housing 11 caused by friction and collision. The buffer plate 26 can effectively absorb and disperse these forces, reducing their direct impact on the housing 11 and the internal circuit board 18. It increases the contact area and stability between the housing 11 and the connecting rod 4, making the housing 11 less prone to shaking or falling off when subjected to external forces, thus ensuring the overall stability of the sign.

[0030] Working principle: The worker pulls the placement plate 22, causing it to leave the placement slot 21. The worker then replaces the advertisement and places it in the placement plate 22. Based on the replaced advertisement, the worker pushes the box 11, causing the sliding rod 7 on the fixing plate 8 to move. This causes the limiting plate 9 to disengage from the limiting slot 10. After rotating the box 11, the worker slowly slides the box 11 downwards, causing another limiting plate 9 to enter the limiting slot 10. This makes the box 11 horizontal. The worker moves the entire device to a suitable position according to the advertisement requirements and uses bolts to fix the device in the appropriate position. According to the required height of the billboard, the worker squeezes the insertion rod 16, causing it to disengage from the insertion slot 12. Then, the connecting rod 4 is moved to a suitable position, and the spring 17 pushes the insertion rod 16 on the baffle 20 into the insertion slot 12, thus fixing the box 11 in the appropriate position.
