Description

Technical Field

[0001] This utility model relates to the field of television accessories technology, specifically to a television frame. Background Technology

[0002] A television screen, also known as a monitor, or more commonly as a display screen or screen, is a device that outputs images or tactile information. If the input signal is an electronic signal, this display device is called an electronic display device; there is also a mechanical display device.

[0003] Chinese invention patent CN 112014994 B discloses a bezel structure and display device for an LCD screen. The bezel structure includes a concave bezel, a sealing bezel, and corner bracket connectors. The concave bezel and the sealing bezel are connected to form a rectangular frame. The concave bezel is formed by bending a profile. The sealing bezel and the two ends of the concave bezel are connected to form a rectangular frame. The joint between the sealing bezel and the concave bezel is connected by corner bracket connectors, and the joint is located at a right angle to the rectangular frame. The corner bracket connectors include a first connecting edge and a second connecting edge perpendicular to the first connecting edge. At least two bolts are provided on both the first and second connecting edges.

[0004] However, the above-mentioned LCD screen frame structure still has the following shortcomings: the two ends of the edge-sealing frame and the concave frame are only connected by corner brackets. Before the corner brackets are installed, the two ends of the edge-sealing frame and the concave frame are not connected together, which can easily cause relative movement and is not conducive to the installation of the corner brackets; each corner bracket needs to be bolted to the edge-sealing frame and the concave frame respectively, making the installation of the corner brackets relatively troublesome.

[0005] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

As a preferred option, the tenon plate 400 is a dovetail plate, and the tenon groove is a dovetail groove.

[0066] It should be noted that each tenon 400 can also be fixed to the second frame 300, and each mortise can also be made in the first frame 200.

[0067] Both the first corner bracket 351 and the second corner bracket 352 include an L-shaped flat corner plate 353. It should be noted that, referring to... Figure 4 The L-shaped planar corner plate 353 has two integrally connected and symmetrically arranged trapezoidal corner plate units. Each trapezoidal corner plate unit has a long base and a short base. The dashed line in the figure is a virtual dividing line between the two trapezoidal corner plate units and is not a real line. In this embodiment, the first corner bracket 351 is located behind the connection position of the first connecting end and the first mating end, and the second corner bracket 352 is located behind the connection position of the second connecting end and the second mating end.

[0068] In the first corner bracket 351, one trapezoidal corner plate unit is arranged opposite to the first mating end. The trapezoidal corner plate unit is integrally connected to a locking foot 354 on the side facing the first mating end. The locking foot 354 includes an integrally connected connecting part and a locking part. One end of the locking part is connected to the trapezoidal corner plate unit, and the other end is connected to one end of the connecting part. The connecting part is arranged parallel to the trapezoidal corner plate unit and is located on the right side of the locking part. Another trapezoidal corner plate unit is arranged opposite to the first connecting end. The trapezoidal corner plate unit has screw holes.

[0069] In the second corner bracket 352, one trapezoidal corner plate unit is arranged opposite to the second mating end. The trapezoidal corner plate unit is integrally connected to a locking foot 354 on the side facing the second mating end. The locking foot 354 includes an integrally connected connecting part and a locking part. One end of the locking part is connected to the trapezoidal corner plate unit, and the other end is connected to one end of the connecting part. The connecting part is arranged parallel to the trapezoidal corner plate unit and is located to the left of the locking part. The other trapezoidal corner plate unit is arranged opposite to the second connecting end. The trapezoidal corner plate unit has screw holes.

[0070] The locking feet 354 of the first corner code 351 and the second corner code 352 are formed by stamping.

[0071] The first mating end and the second mating end are respectively provided with locking holes 340, and each locking hole 340 is arranged in a one-to-one correspondence with each locking foot 354. In this embodiment, there are two locking holes 340. One locking hole 340 is opened on the rear side of the first mating end, and this locking hole 340 is arranged in a corresponding manner with the locking foot 354 of the first corner bracket; the other locking hole 340 is opened on the rear side of the second mating end, and this locking hole 340 is arranged in a corresponding manner with the locking foot 354 of the second corner bracket.

[0072] Each locking pin 354 engages with its corresponding locking hole 340; each L-shaped flat corner plate 353 is locked to the first frame 200 by screws. In this embodiment, the locking part of the locking pin 354 of the first corner bracket 351 engages with the corresponding locking hole 340 on the rear side of the first mating end. One end of the locking pin 354 of the first corner bracket 351 is fixed to the L-shaped flat corner plate 353 of the first corner bracket 351, and the other end of the locking pin 354 of the first corner bracket 351 is located between the corresponding locking hole 340 on the rear side of the first mating end and the corresponding locking hole 340 on the rear side of the second mating end. The L-shaped flat corner plate 353 of the first corner bracket 351 is locked to the second clamping plate 230 near the first mating end by screws. The second angle bracket 352 is positioned such that the locking part of the locking foot 354 engages with the corresponding locking hole 340 on the rear side of the second mating end. One end of the locking foot 354 of the second angle bracket 352 is fixed to the L-shaped flat angle plate 353 of the second angle bracket 352, and the other end of the locking foot 354 of the second angle bracket 352 is located between the corresponding locking hole 340 on the rear side of the first mating end and the corresponding locking hole 340 on the rear side of the second mating end. The L-shaped flat angle plate 353 of the second angle bracket 352 is locked to the position of the second clamping plate 230 near the second mating end by screws. It should be noted that the screws are an existing structure and will not be described in detail here.

[0073] When installing the first corner bracket 351 and the second corner bracket 352, the connecting part of the clip 354 is passed through the corresponding clip hole 340, and then the clip part of the clip 354 is clipped onto the corresponding clip hole 340 on the second frame 300. Finally, a screw is passed through the screw hole of the L-shaped flat corner plate 353 and the L-shaped flat corner plate 353 is locked together with the first frame 200.

[0074] After adopting the above technical solution, before installing the first corner bracket 351 and the second corner bracket 352, the two ends of the first frame 200 and the two ends of the second frame 300 are connected one-to-one through the mortise and tenon structure. During the installation of the first corner bracket 351 and the second corner bracket 352, the two ends of the first frame 200 and the two ends of the second frame 300 are not prone to relative movement, which is conducive to the quick installation of the first corner bracket 351 and the second corner bracket 352. When installing the first corner bracket 351 and the second corner bracket 352, it is only necessary to snap each clip 354 into the corresponding clip hole 340, and then use screws to lock the first corner bracket 351 and the second corner bracket 352 to the rectangular frame respectively. The installation of the first corner bracket 351 and the second corner bracket 352 is relatively convenient.
