Technical Field
[0001] This application relates to the field of LCD bracket technology, and in particular to a single-screen LCD bracket. Background Technology
[0002] LCD stands are primarily used to fix monitors, helping people to better use or view LCD screens and preventing health problems caused by work fatigue. A typical LCD stand includes a mounting base, a first rotating base, a second rotating base, a first connecting rod, a second connecting rod, a gas spring, and an LCD base. The first rotating base is rotatably connected to the outside of the mounting base, and the second rotating base is rotatably connected to the inside of the LCD base. The two ends of the first and second connecting rods are rotatably connected to the first and second rotating bases, respectively. The gas spring is located between the first and second connecting rods, with its two ends rotatably connected to the first and second rotating bases. Because the first and second connecting rods are rotatably connected to the first and second rotating bases, and the gas spring is located between the first and second connecting rods, there is a gap between their ends. Over long-term use, dust from the air can enter the cavity between the first and second connecting rods through this gap. The dust then adheres to the gas spring, affecting its normal operation and, in severe cases, causing it to malfunction. Utility Model Content
[0003] The purpose of this utility model is to provide a single-screen LCD bracket to address the defects and shortcomings of the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The device includes a mounting base, a first rotating base, a second rotating base, a first connecting rod, a second connecting rod, a gas spring, and a liquid crystal base. The first rotating base is rotatably connected to the outside of the mounting base, and the second rotating base is rotatably connected to the inside of the liquid crystal base. The two ends of the first and second connecting rods are respectively rotatably connected to the first and second rotating bases, with the first connecting rod located above the second connecting rod. The gas spring is located between the first and second connecting rods, with its two ends rotatably connected to the first and second rotating bases, respectively. The upper side of the second connecting rod wraps around the lower side of the first connecting rod, and a fan is installed inside the lower side of the second connecting rod. The fan blows air into the inner cavity of the first and second connecting rods and then exits from both ends.
[0006] Preferably, there are two fans, which are located at the two ends of the lower side of the second connecting rod.
[0007] Preferably, two ventilation ducts are provided on the lower side of the second connecting rod, and the two fans are respectively installed and fixed in the two ventilation ducts.
[0008] Preferably, the outlet of the ventilation duct is equipped with a filter screen.
[0009] Preferably, an installation ring is inserted and fixed inside the outer end of the ventilation duct, and the filter screen is installed inside the installation ring.
[0010] Preferably, the side wall of the outer end of the mounting ring is provided with a snap-fit block, and the side wall of the ventilation duct is provided with a snap-fit groove for snap-fit fixing of the snap-fit block. When the snap-fit block is embedded in the snap-fit groove, the inner end of the mounting ring abuts against one side of the fan.
[0011] Preferably, two air guide plates are provided on the inner side of the second connecting rod, and the two air guide plates correspond to the two ventilation ducts respectively, and the air guide plates are inclined inward.
[0012] In summary, this application includes at least one of the following beneficial technical effects:
[0013] 1. When the LCD stand is in use, when the LCD screen is moved to a specific position, the fan at the bottom of the second connecting rod is turned on. Then, under the action of the air guide plate, the air generated by the fan is blown out to the high part of the cavity between the first connecting rod and the second connecting rod, thereby preventing external dust from entering from the gap at the high end of the first connecting rod and the second connecting rod, so that the gas spring is not affected by dust and the service life of the gas spring is maintained.
[0014] 2. An installation ring is fixed to the outer end of the ventilation duct. The installation ring contains a filter screen. When the fan is running, it can draw outside air into the cavity between the first connecting rod and the second connecting rod. Then, under the action of the filter screen, it can prevent dust in the air below the second connecting rod from entering the cavity between the first connecting rod and the second connecting rod, thereby improving the stability of the gas spring.
