Description
Technical Field
[0001] This utility model relates to the field of industrial display equipment, and is particularly applicable to wall-mounted rugged LCD monitors. Background Technology
[0002] Currently, LCD monitors are widely used in many fields such as security monitoring, industrial control, and outdoor advertising. With the continuous expansion of usage scenarios, the requirements for the protective performance and ease of installation of LCD monitors are increasing. Traditional LCD monitors have many shortcomings in their structural design. Firstly, regarding sealing performance, the connection between the front and rear covers is usually fixed with simple screws. The sealing strips are easily damaged due to long-term use or improper installation, allowing dust, moisture, and other foreign objects to enter the monitor, damaging the circuitry and screen, and affecting the monitor's lifespan and stability. Secondly, regarding ease of installation, most use complex brackets or mounting holes, requiring multiple tools and cumbersome steps to complete the installation. This not only increases installation costs but also limits the flexibility and applicability of the equipment. Therefore, there is an urgent need for a wall-mounted rugged LCD monitor with good sealing performance and easy assembly to solve the above problems. Utility Model Content
[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0004] A rugged LCD monitor mounting structure includes a housing, an LCD screen, a wall mount, a circuit control module for controlling the LCD screen, and a cuboid cover. The cuboid cover is fixed inside the housing and divides the housing into two independent chambers, a first chamber and a second chamber. The LCD screen and the circuit control module are installed in the first chamber. The outer wall of the housing has wall-mounting holes. The wall mount is fixed to a wall. The wall mount has L-shaped hooks that extend into the wall-mounting holes and are placed in the second chamber. The L-shaped hooks cooperate with the wall-mounting holes to achieve wall mounting of the monitor.
[0005] The housing of this invention is made of sheet metal, which is high-strength, durable, and does not deform. Furthermore, the housing coating undergoes an oxidation anti-corrosion treatment. A cuboid cover is designed above the wall-mounting hole. This design works in conjunction with the L-shaped hooks on the wall mount to achieve quick wall-mounting of the device. After installation, the L-shaped hooks are completely covered by the cuboid cover, providing excellent anti-detachment performance and completely preventing dust or liquid from entering the monitor's interior through the wall-mounting hole. By employing this special structural combination, the LCD monitor's three-proof performance (waterproof, dustproof, and moisture-proof) can be effectively improved.
[0006] The circuit control module includes a sheet metal module bracket, a power supply module, and a detection motherboard module. The circuit control module is fixed inside the housing by the sheet metal module bracket, and the power supply module and the detection motherboard module are fixed on the sheet metal module bracket. One side of the sheet metal module bracket has a bend to fix the wire harness, which can effectively avoid the cables being messy inside the equipment, reduce interference between cables, and improve the stability of equipment operation. This layered fixing structure is conducive to the rational use of internal space and heat dissipation.
[0007] Preferably, the housing includes a sheet metal front cover, a sheet metal rear cover, and a sheet metal housing bracket. The sheet metal housing bracket includes four independent brackets, which are respectively disposed between the LCD screen and the sheet metal front cover, and are connected end to end to form a ring-shaped sheet metal housing bracket. The sheet metal housing bracket and the LCD screen are fixed together on the four sides of the sheet metal front cover.
[0008] The four independent brackets of the sheet metal housing bracket all adopt an L-shaped double-step structure design, forming a first bending structure and a second bending structure. The first bending structure and the edge of the sheet metal front cover form a groove, and the second bending structure is provided with mounting holes. The sheet metal rear cover is fixed to the back of the sheet metal housing bracket through the second bending structure.
[0009] The above setup not only provides a stable support for the LCD screen, but also achieves waterproofing through the groove it forms. Meanwhile, the threaded holes on the second bending structure facilitate the fixing of the sheet metal back cover, making the overall structure of the equipment more compact and reasonable.
[0010] Preferably, a waterproof gasket is provided in the groove, which can effectively prevent foreign objects such as dust and moisture from entering the equipment from the assembly gap, thereby protecting core components such as the LCD screen and circuit control module, ensuring stable operation of the equipment in harsh environments, and extending its service life.
[0011] Preferably, a moisture-proof cotton is attached around the edge of the inner display area of the sheet metal front cover, which can further enhance the moisture-proof performance of the device and effectively prevent moisture from entering the device from the edge of the display area.
[0012] Preferably, the sheet metal back cover has a recessed portion, and a component interface is provided on one side of the recessed portion.
[0013] Preferably, the L-shaped hook has a 30-degree chamfer at the bend, which facilitates quick insertion and mating with the wall-mounting hole of the sheet metal back cover, enabling convenient wall-mounting installation of the equipment.
[0014] The beneficial effects of this utility model are:
[0015] The assembly design employing this unique structure facilitates the installation and disassembly of the LCD screen during production and maintenance. Furthermore, the design creates a relatively enclosed space between the cubic cover and the sheet metal back cover. Combined with waterproof gaskets on the edges of the sheet metal housing bracket and the sheet metal front cover, as well as moisture-proof cotton on the inner edge of the display area of the sheet metal front cover, this further enhances the equipment's sealing and protection system. It prevents external dust, moisture, and other foreign objects from entering the equipment through the gap between the wall-mounting holes and the L-shaped mounting holes, thus better protecting the LCD screen and core components such as the circuit control module. This allows the equipment to operate stably for extended periods even in harsh environments, effectively improving the LCD screen's three-proof performance (waterproof, dustproof, and moisture-proof).

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] like Figures 1 to 4As shown, the installation structure of a rugged LCD monitor according to this utility model includes a housing 1, an LCD screen 2, a wall mount 3, a circuit control module 4 for controlling the LCD screen 2, and a cuboid cover 5. The cuboid cover 5 is fixed inside the housing 1 and divides the housing 1 into two independent chambers, namely a first chamber 6 and a second chamber 7. The LCD screen 2 and the circuit control module 4 are installed in the first chamber 6. The outer wall of the housing 1 is provided with four wall-mounting holes 8. The wall mount 3 is fixed to the wall. The wall mount 3 is provided with four L-shaped hooks 31. The L-shaped hooks 31 extend into the wall-mounting holes 8 and are placed in the second chamber 7. The L-shaped hooks 31 cooperate with the wall-mounting holes 8 to realize the wall-mounting installation of the monitor. The four L-shaped hooks 31 are designed with a 30-degree chamfer so that the monitor fits tightly against the wall mount 3. When maintenance is required, it can be directly removed without removing screws.
[0023] like Figure 1 As shown, the housing 1 includes a sheet metal front cover 11, a sheet metal rear cover 12, and a sheet metal housing bracket 13. The sheet metal housing bracket 13 includes four independent brackets, which are respectively located between the LCD screen 2 and the sheet metal front cover 11 and are connected end to end to form a ring-shaped sheet metal housing bracket 13. The sheet metal housing bracket 13 and the LCD screen 2 are screwed together and fixed to the four sides of the sheet metal front cover 11. The sheet metal rear cover 12 has a recessed part, and a component interface is provided on one side of the recessed part. A moisture-proof cotton 10 is attached around the edge of the display area inside the sheet metal front cover 11.
[0024] like Figure 2 As shown, the four independent supports of the sheet metal housing bracket 13 all adopt an L-shaped double-step structure design, forming a first bending structure 131 and a second bending structure 132. The first bending structure 131 and the edge of the sheet metal front cover 11 form a groove 133. A waterproof gasket 9 is provided in the groove 133. The second bending structure 132 is provided with a threaded mounting hole. The sheet metal rear cover 12 is fixed to the back of the sheet metal housing bracket 13 by screws through the threaded mounting holes on the second bending structure 132. When the sheet metal rear cover 12 is tightly connected to the sheet metal housing bracket 13 by screws, the installation force will simultaneously compress the waterproof gasket 9 in the groove 133. The waterproof gasket 9 will produce elastic deformation to fill the assembly gap between the sheet metal rear cover 12 and the sheet metal front cover 11, thereby forming a reliable sealing structure and effectively preventing external dust and liquid from entering the equipment through the assembly gap.
[0025] like Figure 1 As shown, the circuit control module 4 includes a sheet metal module bracket, a power supply module, and a detection motherboard module. The circuit control module is fixed to the back of the sheet metal housing bracket by screws. The power supply module and the detection motherboard module are fixed to the back of the sheet metal module bracket by screws. One side of the sheet metal module bracket has a bend for fixing the wiring harness.
[0026] When assembling this utility model, before installing the LCD screen 2 into the sheet metal front cover 11, firstly, moisture-proof cotton 10 is pasted around the inner side wall of the sheet metal front cover 11 and the edge of the display area of the LCD screen 2. Next, the four independent brackets of the sheet metal housing bracket 13 are installed and fixed in the gap between the LCD screen 2 and the sheet metal front cover 11, so that the first bending structure 131 of each bracket of the sheet metal housing bracket 13 forms a groove 133 with the sheet metal front cover 11. This groove 133 is used to place the waterproof gasket 9. Then, the power module and the detection motherboard module are installed and fixed onto the LCD screen 2 through the sheet metal module bracket. The sheet metal rear cover 12 is fixed to the second bending structure 132 of the sheet metal housing bracket 13 with mounting screws to complete the assembly. Because a cuboid cover 5 is provided above the wall mounting hole 8 of the sheet metal rear cover 12, the wall mounting hole 8 of the sheet metal rear cover 12 is a fully enclosed space. Finally, the wall mount 3 is installed and fixed on the wall, and the assembled monitor is suspended on the wall mount 3 to complete the assembly.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
