Description

Technical Field

[0001] This utility model relates to the field of installation and fixing technology of aluminum mid-frame of television, specifically an anti-slip limiting and fixing structure for aluminum mid-frame of television. Background Technology

[0002] As televisions become thinner, lighter, and higher-definition, the aluminum frame, as a core supporting component, directly affects the overall performance of the device due to the stability of its connection with the back cover and front frame. Traditional television frames are mostly fixed with screws, which can ensure connection strength, but the assembly process is cumbersome, and the screws are prone to loosening due to vibration during long-term use, affecting structural stability. At the same time, if the contact surface between the aluminum frame and the back cover lacks anti-slip design, relative sliding is likely to occur, which not only produces abnormal noise, but may also reduce the service life of the components due to friction and wear, making it difficult to meet the requirements of modern televisions for assembly efficiency and structural reliability.

[0003] In existing technologies, some TV frames attempt to use snap-fit ​​structures to replace screws, but snap-fit ​​structures are mostly fixed in one direction and lack elastic buffer design. During installation or disassembly, uneven force can easily cause damage to components. In addition, there is no special anti-slip structure to address the sliding problem between the aluminum frame and the back cover, resulting in insufficient tightness. Furthermore, the installation of the back cover and front frame with traditional snap-fit ​​structures often interferes with each other, requiring step-by-step operation during installation and disassembly, which is inefficient and cannot meet the needs of mass production. Therefore, we propose an anti-slip limiting and fixing structure for the aluminum frame of a TV. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-slip limiting and fixing structure for the aluminum frame of a television set, thus solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an anti-slip limiting and fixing structure for an aluminum frame of a television set, comprising: The aluminum frame includes an anti-slip pad, a back cover, a front frame, and a clamping device. Two clamping devices are symmetrically distributed on each of the two opposite sidewalls of the aluminum frame. A back cover and a front frame are respectively located on each of the two opposite sidewalls. A connecting rod 1 is located at each of the four corners of the sidewall end face of the back cover, and a connecting rod 2 is located at each of the four corners of the sidewall end face of the front frame. Both connecting rod 1 and connecting rod 2 engage with the clamping device. The anti-slip pad is located between the aluminum frame and the back cover.

[0006] Preferably, the aluminum frame sidewall end face is provided with a mating groove, and the mating groove is in the form of a rectangular ring structure. The mating groove is correspondingly bonded with an anti-slip pad, and the sidewall of the anti-slip pad is attached to the side edge of the end face of the rear cover sidewall. Furthermore, a clamping cavity is provided inside both ends of the two opposite sidewalls of the aluminum frame.

[0007] Preferably, the clamping cavity has a rectangular slot on the side wall of the aluminum frame, and the clamping cavity has an insertion hole one on the top of the inner wall of the rear cover, and an insertion hole two on the bottom of the inner wall of the front frame.

[0008] Preferably, the first connecting rod and the second connecting rod have the same structure, and the first connecting rod is in an L-shaped structure. The side wall of the shaft end of the first connecting rod is provided with a locking block. The first connecting rod is inserted into the first socket, and the second connecting rod is inserted into the second socket.

[0009] Preferably, the clamping device includes a rear cover clamping member and a front frame clamping member, and the bottom of the rear cover clamping member is provided with a sliding groove, and the top of the front frame clamping member is provided with a sliding strip. Both the sliding groove and the sliding strip have convex cross-sections, and the sliding strip is slidably connected to the sliding groove.

[0010] Preferably, the back cover clamping member has four springs symmetrically distributed on its side wall, and a mating plate is welded to the shaft end of the spring group. The mating plate is in contact with the inner wall of the clamping cavity. The back cover clamping member has a slot inside, which is engaged with the clamping block. The springs, mating plate and slot are all placed inside the clamping cavity. The side of the back cover clamping member away from the mating plate is slidably connected to the rectangular slot of the clamping cavity.

[0011] Preferably, the front frame clamping member and the rear cover clamping member have the same external structure, and the front frame clamping member and the rear cover clamping member are symmetrically distributed at the origin.

[0012] Compared with the prior art, this utility model provides an anti-slip limiting and fixing structure for the aluminum frame of a television set, which has the following beneficial effects: The anti-slip limiting and fixing structure of the aluminum frame of this TV effectively improves the connection stability between the aluminum frame and the back cover and front frame through the coordinated design of anti-slip rubber pads and clamping devices. The anti-slip rubber pads fit between the mating groove and the back cover, reducing relative sliding between components, reducing wear during long-term use, and enhancing sealing tightness. The clamping device adopts a spring-driven slot and block engagement structure, replacing the traditional screw connection. This not only simplifies the installation process and reduces disassembly and assembly time, but also avoids the thread damage caused by repeated screw disassembly and assembly. In addition, the sliding fit design of the back cover clamping part and the front frame clamping part ensures that the disassembly and assembly of the back cover and the front frame do not interfere with each other, improving maintenance convenience. The overall structure extends the service life of the equipment while ensuring connection strength. Attached Figure Description

[0024] Working principle: The anti-slip limiting and fixing structure of the aluminum frame of the TV is correctly installed according to the diagram. Each end of the two opposite side walls of the aluminum frame 1 has a clamping cavity 6. A clamping device 5, consisting of a rear cover clamping component 13 and a front frame clamping component 14, is installed inside the clamping cavity 6. These two components slide together via a groove 19 and a sliding strip 20 with a convex structure, ensuring smooth assembly and disassembly and preventing interference. Anti-slip pads 2 are adhered to the rectangular annular groove 7 on the side wall of the aluminum frame 1. When the rear cover 3 is installed, the L-shaped connecting rods 8 at its four corners are inserted into the clamping cavity 6 through the insertion holes 10. At this time, the rear cover clamping component 13 is pressed down. The pressing block 18 compresses the spring 15.

The installation process of the front frame 4 is the same. Its connecting rod 2 9 is inserted from the insertion hole 2 11 and is clamped by the front frame clamping member 14. At the same time, the anti-slip pad 2 is attached to the side wall of the back cover 3. It uses its own elasticity to reduce the sliding friction between the aluminum middle frame 1 and the back cover 3. With the mechanical limit of the clamping device 5, a double fixation is formed. The rigid connection is achieved through the clamping structure, and the tightness of the fit is enhanced by the anti-slip pad 2, ensuring the stable assembly of the overall structure.
