Description

Technical Field

[0001] This utility model relates to the field of reflective signage technology, and in particular to glass microbead reflective signage. Background Technology

[0002] Reflective signs are a type of signage that uses reflective film as its core material and relies on special optical principles to achieve high visibility. Their surfaces are usually coated with reflective materials containing glass microbeads or microprism structures, which can efficiently reflect incident light back to the direction of the light source, quickly conveying information such as directional guidance and safety warnings, allowing sufficient reaction time for drivers and workers, effectively reducing the risk of accidents, and are an important facility for ensuring public safety.

[0003] Among them, glass microbead reflective signs have a better reflective effect. The glass microbeads are embedded and pasted into the paint surface of the sign by being painted on it, so that the glass microbeads are fixed and installed on the outer surface of the paint surface. When a light source shines on the glass microbeads, they can reflect the light source. However, after the glass microbeads are embedded in the paint surface, the installation position of the glass microbeads cannot be changed, and different signs cannot be displayed according to different usage locations. Therefore, there is an urgent need for a glass microbead reflective sign. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a glass microbead reflective sign, which aims to improve the problem that after the glass microbeads are embedded in the paint surface, the installation position of the glass microbeads cannot be changed, and different sign patterns cannot be displayed according to different usage locations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass microbead reflective sign, including a fixing frame, an mounting plate fixedly installed on the inner wall of the fixing frame, an annular groove one opened at the top of the fixing frame, an annular groove two opened at the bottom of the inner wall of the fixing frame, a sliding column slidably installed inside the annular groove two, a connecting rod sleeved on the top of the outer surface of the sliding column, a snap-fit ​​groove opened inside the connecting rod, a connecting sleeve fixedly installed on the top of the connecting rod, a sliding rod threadedly connected inside the connecting sleeve, an insertion interface opened on the outer surface of the connecting rod, and a shielding cloth installed inside the insertion interface.

[0006] Through the above technical solution, the bottom of the connecting rod can be sleeved on the outer surface of the sliding column, so that the bottom of the connecting rod is limited and installed on the outer surface of the sliding column. At this time, the top of the connecting rod is at the bottom of the inner wall of the fixing frame, and the connecting sleeve can be fixedly installed on the top of the connecting rod. The connecting sleeve is located inside the first annular groove, so that the sliding rod can be inserted from the top of the connecting sleeve into the snap-fit ​​groove opened inside the connecting rod, and the bottom of the sliding rod can be inserted into the inside of the sliding column, so that the sliding rod can limit and fix the connecting rod and the sliding column. The connecting rod can slide inside the first annular groove and the second annular groove with the help of the sliding column and the connecting sleeve.

[0007] Preferably, one end of the insertion interface passes through the connecting rod and extends into the interior of the snap-fit ​​groove. There are two insertion interfaces, which are symmetrically distributed inside the connecting rod.

[0008] Preferably, the bottom of the sliding rod passes through the connecting sleeve and the snap-fit ​​groove and extends into the interior of the sliding column, and the top of the sliding rod passes through the annular sliding groove and is fixedly installed with a pulling block.

[0009] Preferably, a paint frame is fixedly installed on the outer wall of the mounting plate, the paint frame is filled with paint, and glass microspheres are installed on the outer surface of the paint.

[0010] Preferably, there are two connecting rods, which are symmetrically distributed outside the shielding cloth.

[0011] Preferably, a support frame is fixedly installed at the bottom of the fixed frame, and an adjusting rod is slidably sleeved on the outer surface of the support frame.

[0012] Preferably, the adjusting rod is internally threaded with a threaded post, which passes through the adjusting rod on the side near the support frame and extends to the outer wall of the support frame.

[0013] Preferably, there are two support frames and two adjusting rods, and the two support frames and two adjusting rods are symmetrically distributed at the bottom of the fixed frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the sliding rod can limit and fix the connecting rod and the sliding column. When the sliding rod is inserted into the slot, it can squeeze the side of the shielding cloth inside the slot. Thus, the side of the shielding cloth can be limited and installed into the slot through the sliding rod. The shielding cloth is outside the painting frame, and the glass microbeads can only be exposed through the cut text or pattern, so that the glass microbeads can present different logo patterns or text. This achieves the effect of changing the reflective pattern or text of the glass microbead sign simply by changing the shielding cloth, and can be used in more scenarios.

[0016] 2. In this utility model, the two connecting rods can be snapped and fixed to the two sides of the two shielding cloths inside the connecting rods. The two shielding cloths form a ring. Then, by pulling the pulling block, the two connecting rods are driven to rotate inside the annular slide groove one and the annular slide groove two, so that the two shielding cloths can be switched outside the painting frame, achieving the effect of quickly switching different reflective patterns or text on the glass microbead sign.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1-5An embodiment of this utility model provides a glass microbead reflective sign, including a fixing frame 1. An mounting plate 11 is fixedly installed on the inner wall of the fixing frame 1. An annular groove 101 is opened at the top of the fixing frame 1, and an annular groove 102 is opened at the bottom of the inner wall of the fixing frame 1. A sliding column 103 is slidably installed inside the annular groove 102. A connecting rod 105 is sleeved on the top of the outer surface of the sliding column 103. A snap-fit ​​groove 106 is opened inside the connecting rod 105. A connecting sleeve 107 is fixedly installed on the top of the connecting rod 105. A sliding rod 108 is threadedly connected inside the connecting sleeve 107. An insertion interface 109 is opened on the outer surface of the connecting rod 105. A shielding cloth 110 is installed inside the insertion interface 109.

[0026] The bottom of the sliding rod 108 passes through the connecting sleeve 107 and the snap-fit ​​groove 106 and extends into the interior of the sliding column 103. The top of the sliding rod 108 passes through the annular sliding groove 101 and is fixedly installed with the pulling block 4.

[0027] A painting frame 2 is fixedly installed on the outer wall of the mounting plate 11. Paint 21 is placed inside the painting frame 2, and glass microspheres 22 are installed on the outer surface of the paint 21. Two connecting rods 105 are provided, and the two connecting rods 105 are symmetrically distributed outside the shielding cloth 110.

[0028] Specifically, the interior of the fixing frame 1 is designed as a hollow structure, and the mounting plate 11 is vertically installed inside the fixing frame 1, dividing the interior of the fixing frame 1. A certain gap is left between the left and right sides of the mounting plate 11 and the inner walls of the fixing frame 1. The sliding column 103 is slidably installed inside the second annular groove 102. An interface matching the diameter of the sliding column 103 is provided at the bottom of the connecting rod 105, allowing the bottom of the connecting rod 105 to fit onto the outer surface of the sliding column 103, thus limiting the bottom of the connecting rod 105 to be installed on the outer surface of the sliding column 103. At this time, the top of the connecting rod 105 is at the bottom of the inner wall of the fixing frame 1, and the connecting sleeve 107 can be fixedly installed on the top of the connecting rod 105. The connecting sleeve 107 is located inside the first annular groove 101, allowing the sliding rod 108 to be inserted from the top of the connecting sleeve 107 into the snap-fit ​​groove 106 inside the connecting rod 105, and the bottom of the sliding rod 108 to be inserted into the sliding column 102. Inside 03, the sliding rod 108 can limit and fix the connecting rod 105 to the sliding post 103. The connecting rod 105 can slide inside the annular groove 101 and the annular groove 102 with the help of the sliding post 103 and the connecting sleeve 107. Then, pulling the pulling block 4 at the top of the sliding rod 108 can drive the connecting rod 105 to move along the annular groove 101 and the annular groove 102, so that the side of the shielding cloth 110 is inserted into the insertion interface 109, so that the shielding cloth 110 can be inserted into the insertion interface 109. The side of the baffle can enter the interior of the snap-fit ​​groove 106. When the sliding rod 108 is inserted into the interior of the snap-fit ​​groove 106, the diameter of the snap-fit ​​groove 106 is larger than the diameter of the sliding rod 108. Therefore, the shielding cloth 110 will not affect the insertion of the sliding rod 108 into the interior of the snap-fit ​​groove 106. Furthermore, the sliding rod 108 can squeeze the side of the shielding cloth 110 that has entered the interior of the snap-fit ​​groove 106. Thus, the side of the shielding cloth 110 can be limited and installed into the interior of the snap-fit ​​groove 106 by the sliding rod 108.

[0029] Two connecting rods 105 can be used to limit and fix the two sides of the masking cloth 110. Pulling the connecting rods 105 can straighten the masking cloth 110, so that the masking cloth 110 is outside the painting frame 2. The paint 21 is applied to the inside of the painting frame 2, so that the paint 21 adheres to the outer wall of the mounting plate 11. The mounting plate 11 is made of stainless steel with a thickness of 0.7-2mm. The surface is treated with electrolytic corrosion to enhance the adhesion of the paint 21. Glass microspheres 22 are embedded in the paint 21 applied inside the painting frame 2. The glass microspheres 22 account for 30%-40% of the paint 21. They are evenly distributed through the spraying process. The outer surface of the exposed paint 21 of the microbeads 22 is coated with a 0.1-0.2mm thick silicone-modified polyurethane coating, which is scratch-resistant and prevents the glass microbeads 22 from falling off. The light transmittance is ≥95% and does not affect the reflectivity of the glass microbeads 22. The required patterns or text, such as "No Entry" or "Caution," can be cut out inside the shielding cloth 110. The glass microbeads 22 can only be exposed through the cut text or patterns, so that the glass microbeads 22 can present different signs or text. This achieves the effect of changing the reflective pattern or text of the glass microbead 22 sign simply by changing the shielding cloth 110, and can be used in more scenarios.

[0030] When it is necessary to frequently or periodically change the warning pattern or text, the two insertion interfaces 109 on the outer surface of the connecting rod 105 both penetrate into the inside of the snap-fit ​​groove 106. The two shielding cloths 110 can be snapped into the inside of the connecting rod 105 through the inside of one connecting rod 105. The two connecting rods 105 can snap and fix the two sides of the two shielding cloths 110 into the inside of the connecting rod 105. Then, by moving the pull block 4, the two connecting rods 105 are driven to rotate inside the annular slide groove 101 and the annular slide groove 202, so that the two shielding cloths 110 can be switched outside the painting frame 2, so as to shield different parts of the glass microbeads 22 and display the pattern or text cut out by the shielding cloth 110, so as to achieve the effect of quickly switching different reflective patterns or texts on the glass microbeads 22 sign.

[0031] It is important to note that the glass microspheres 22 require pretreatment before embedding. They should be soaked in a silane coupling agent solution for 10–15 minutes and dried to improve compatibility with the resin. Paint 21 is prepared using automotive paint. The glass microspheres 22 are mixed with acrylic resin, leveling agent, and anti-settling agent, with the stirring speed controlled at 300–500 rpm to prevent breakage. A spraying process combined with surface modification of the glass microspheres 22 is used to enhance the bonding strength between the glass microspheres 22 and paint 21, reducing detachment. For the topcoat 21, acrylic resin and silane-modified glass microspheres 22 (50–100 μm particle size) are mixed at a 6:4 mass ratio, with 1.5% leveling agent added. The mixture is stirred for 10 minutes, sprayed to a thickness of 80–100 μm, and dried at 100°C for 20 minutes. This creates a convex surface on the exposed portion of the glass microspheres 22, increasing their embedding stability and reflective effect.

[0032] Considering the issue of how to adjust the placement of signs at different heights, refer to Figure 1 A support frame 3 is fixedly installed at the bottom of the fixed frame 1, and an adjusting rod 31 is slidably sleeved on the outer surface of the support frame 3.

[0033] The adjusting rod 31 is internally threaded with a threaded post 32. The threaded post 32 passes through the adjusting rod 31 on the side near the support frame 3 and extends to the outer wall of the support frame 3.

[0034] There are two support frames 3 and two adjusting rods 31, which are symmetrically distributed at the bottom of the fixed frame 1.

[0035] Specifically, two support frames 3 are fixedly installed at the bottom of the fixed frame 1, and two adjusting rods 31 are slidably sleeved on the outer surfaces of the two support frames 3 respectively. Thus, the support frames 3 can be pulled and extended inside the adjusting rods 31 to adjust the fixed frame 1 to different heights. The threaded column 32 is threadedly connected to the inside of the adjusting rods 31, so that the threaded column 32 can rotate and abut against the outer wall of the support frame 3 inside the adjusting rods 31. Thus, the threaded column 32 can limit and fix the height of the support frame 3 after it is pulled and adjusted, so as to achieve the effect of adjusting the fixed frame 1 to different heights. This makes it easier for the fixed frame 1 to set the glass microspheres 22 to different heights and increase the reflective effect.

[0036] Working principle: When using the sign, move the adjusting rod 31 to the appropriate location to move the fixed frame 1. Pull the support frame 3 to extend and retract inside the adjusting rod 31 to adjust the fixed frame 1 to a suitable height. Sleeve the bottom of the connecting rod 105 onto the outer surface of the sliding column 103. At this time, the top of the connecting rod 105 is at the bottom of the inner wall of the fixed frame 1, and the connecting sleeve 107 is inside the annular groove 101. Insert the side of the shielding cloth 110 into the insertion interface 109, so that the side of the shielding cloth can enter the locking groove 106. Insert the sliding rod 108 from the top of the connecting sleeve 107 into the locking groove 106, and insert the bottom of the sliding rod 108 into the sliding column 103, so that the sliding rod 108 can connect the connecting rod 105 and the sliding column 103. 3. Limiting and fixing connection: When the sliding rod 108 is inserted into the snap-fit ​​groove 106, the sliding rod 108 can squeeze the side of the shielding cloth 110 inside the snap-fit ​​groove 106. Thus, the sliding rod 108 can limit and install the side of the shielding cloth 110 into the snap-fit ​​groove 106. The two connecting rods 105 can limit and fix the two sides of the shielding cloth 110. By pulling the connecting rods 105, the shielding cloth 110 can be straightened, so that the shielding cloth 110 is outside the paint frame 2. The glass microbeads 22 can only be exposed through the cut text or pattern, so that the glass microbeads 22 can present different logo patterns or text. The effect of changing the reflective pattern or text of the glass microbead 22 sign can be achieved by simply changing the shielding cloth 110, which can be used in more scenarios.

[0037] When it is necessary to frequently or periodically change the warning pattern or text, the two connecting rods 105 can be snapped and fixed to the two sides of the two shielding cloths 110 inside the connecting rods 105. The two shielding cloths 110 form a ring. Then, by pulling the pulling block 4, the two connecting rods 105 can be rotated inside the annular slide groove 101 and the annular slide groove 102, so that the two shielding cloths 110 can be switched outside the painting frame 2 to shield different parts of the glass microbeads 22 and display the pattern or text cut out by the shielding cloths 110, so as to achieve the effect of quickly switching different reflective patterns or texts on the glass microbeads 22 sign.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
