[0030] Figure 1 is a three-dimensional diagram of an embodiment of the display screen frame 2, Figure 2 2 is an exploded schematic diagram of a display screen assembly 4 having a display screen frame 2. Figure 1 , Figure 2 The display screen frame 2 is used to install the display screen 1, and includes: a plurality of frame parts 3. For example, when the display screen 1 is rectangular or square, the frame parts 3 include four, and the adjacent frame parts 3 are connected to each other to form a closed-loop frame that can accommodate the display screen 1. The existing frame parts 3 are fixedly connected to each other, such as fastened by threaded connection or other quick disassembly and assembly methods. The display screen frame 2 of the following embodiment is different from the existing display screen frame 2 in that the plurality of frame parts 3 include a fixed frame part 31 that can fasten the display screen 1, and at least one rotating frame part 32 that can rotate relative to the fixed frame part 31.

[0031] The plurality of frame portions 3 include: a first frame portion 311, a second frame portion 321, a third frame portion 312, and a fourth frame portion 322. For ease of explanation, the frame portion 3 located below the display screen frame 2 is referred to as the first frame portion 311, the frame portion 3 located to the left (side) of the display screen frame 2 is referred to as the second frame portion 321, the frame portion 3 located above the display screen frame 2 is referred to as the third frame portion 312, and the frame portion 321 located to the right (side) of the display screen frame 2 is referred to as the fourth frame portion 322. The first frame portion 311 and the third frame portion 312 are opposite, and the second frame portion 321 and the fourth frame portion 322 are opposite. The four frame portions 3 are respectively connected to form a closed-loop frame for accommodating the display screen 1. Among them, the starting end 321a and the ending end 321b of the second frame portion 321 are adjacent to and orthogonal to the starting end 311a of the first frame portion 311 and the starting end 312a of the third frame portion 312 respectively; the starting end 322a and the ending end 322b of the fourth frame portion 322 are adjacent to and orthogonal to the ending end 311b of the first frame portion 311 and the ending end 312b of the third frame portion 312 respectively.

[0032] In this embodiment, the first frame portion 311 and the third frame portion 312 are taken as the fixed frame portion 31 , and the second frame portion 321 and the fourth frame portion 322 are taken as the rotating frame portion 32 for detailed description.

[0033] The display screen frame 2 may include a base 21, the lower portion of the first frame portion 311 is fixed to the base 21 by screws, the upper portion of the first frame portion 311 is provided with a plurality of through holes or threaded holes (not shown in the figure) along its length direction, the third frame portion 312 is also provided with a plurality of through holes or threaded holes (not shown in the figure) at its lower portion, and correspondingly, the display screen 1 is also provided with a plurality of threaded holes or through holes (not shown in the figure) at its lower and upper sides, respectively, so as to lock the display screen 1 to the fixed frame portion 31 (i.e., the first frame portion 311 and the third frame portion 312). The display screen frame 2 also includes a back cover 22, which is fixed to the display screen 1 by screws after the display screen 1 is installed.

[0034] FIG3(a) is an exploded schematic diagram of the frame portion 3 (fixed frame portion 31 / third frame portion 312), FIG3(b) is a front view of the frame portion 3, and FIG3(c) is a cross-sectional view taken along line AA of FIG3(b). Figure 3(a)-Figure 3(c) , each frame part 3 (i.e., whether it is a fixed frame part 31 or a rotating frame part 32) includes a main frame part 3a and an auxiliary frame part 3b, respectively, and the structures of the main frame part 3a and the auxiliary frame part 3b of each frame part 3 are roughly the same. Specifically, both the main frame part 3a and the auxiliary frame part 3b can use extruded aluminum profiles. The main frame part 3a is the main fixed part, and the auxiliary frame part 3b is engaged with the main frame part 3a. The engagement method can choose an existing buckle structure, such as providing a plurality of card slots 3c on the main frame part 3a, and providing a plurality of card blocks 3d that cooperate with the card slots 3c on the auxiliary frame part 3b. After the auxiliary frame part 3b is engaged with the main frame part 3a, a first groove 3e extending along the length direction of the main frame part 3a is formed. When the display screen frame 2 is closed, the opening of the first groove 3e of each frame part 3 faces the central area 2a of the display screen frame 2. Thus, a storage space for accommodating glass (not shown) for protecting the display screen 1 is formed.

[0035] By providing the engaging structure of the auxiliary frame member 3b and the main frame member 3a, the glass can be easily disassembled. Moreover, the second frame portion 321 and the fourth frame portion 322 can be assisted to rotate relative to the first frame portion 311 and the third frame portion 312. That is, when the second frame portion 321 and / or the fourth frame portion 322 needs to be rotated, the auxiliary frame member 3b can be disassembled, the glass can be removed, and then the second frame portion 321 and / or the fourth frame portion 322 can be rotated.

[0036] Figure 4 3 is a schematic diagram showing that the rotating frame portion 32 (the second frame portion 321 ) is connected to the fixed frame portion 31 (the third frame portion 312 ) via the first rotating portion 33 . Figure 5 is a cross-sectional schematic diagram showing the connection between the second frame portion 321 and the third frame portion 312 through the first rotating portion 33. Figure 63 is an exploded schematic diagram of the first rotating portion 35 and the first latch portion 354 of the first rotating portion 33. Figure 4-Figure 6 , the rotating frame portion 32 is connected to the fixed frame portion 31 through the first rotating portion 33. Each first rotating portion 33 has: a first fixed portion 34 and a first rotating portion 35, and the first rotating portion 35 rotates relative to the first fixed portion 34. The first fixed portion 34 is arranged on the fixed frame portion 31, and the first rotating portion 35 is arranged on the rotating frame portion 32. Specifically, the head end 321a and the tail end 321b of the second frame portion 321 are respectively connected to the head end 311a of the first frame portion 311 and the head end 312a of the third frame portion 312 through a first rotating portion 33, that is: the head end 321a and the tail end 321b of the second frame portion 321 are respectively installed with a first rotating portion 35, and the head end 311a of the first frame portion 311 and the head end 312a of the third frame portion 312 are respectively provided with a first fixed portion 34. Similarly, the head end 322a and the tail end 322b of the fourth frame portion 322 are also connected to the tail end 311b of the first frame portion 311 and the tail end 311b of the third frame portion 312 through a first rotating portion 33, that is, the head end 322a and the tail end 322b of the fourth frame portion 322 are respectively installed with a first rotating portion 35, and the tail end 311b of the first frame portion 311 and the tail end 312b of the third frame portion 312 are respectively provided with a first fixing portion 34.

[0037] Thus, the second frame portion 321 can rotate relative to the first frame portion 311 and the third frame portion 312 through the two first rotating portions 33, and the fourth frame portion 322 can also rotate relative to the first frame portion 311 and the third frame portion 312 through the other two first rotating portions 33. Thus, the display screen frame 2 is closed (i.e., a closed loop frame is formed) or opened at the second frame portion 321 and / or the fourth frame portion 322.

[0038] The four first rotating parts 33 are substantially the same except for slightly different installation directions. Therefore, for the sake of convenience, only the first rotating parts 33 respectively connected to the third frame part 312 and the second frame part 321 are described below.

[0039] As described above, the first rotating portion 33 includes the first fixed portion 34 and the first rotating portion 35 . The first rotating portion 35 can rotate around the first fixed portion 34 in a variety of ways.

[0040] In a preferred embodiment of the first rotating portion 33, the first fixing portion 34 includes a first hole portion 341, and the first hole portion 341 is arranged at the head end of the fixed frame portion 31 and / or the end of the fixed frame portion 31. That is, in this embodiment, the first hole portion 341 is arranged on the head end 312a of the third frame portion 312, and specifically, the first hole portion 341 is a through pin hole, which is opened on the main frame member 3a of the third frame portion 312.

[0041] The first rotating portion 35 includes a first rotating member 351, and the first rotating member 351 is installed at the head end of the rotating frame portion 32 and / or the end of the rotating frame portion 32, that is, in this embodiment, the first rotating member 351 is installed at the end 321b of the second frame portion 321, and the first rotating portion 35 is connected to the main frame member 3a' of the second frame portion 321 through the first rotating member 351, such as the first rotating member 351 and the main frame member 3a of the second frame portion 321 are connected by screws 36.

[0042] The first rotating part 35 further includes a first rotating shaft 352. Specifically, a first connecting hole 353 is provided on the first rotating part 351. The first rotating shaft 352 passes through the first hole 341 from one end 341a of the first hole 341 and enters into the first connecting hole 353 located at the other end 341b of the first hole 341. That is, in this embodiment, the first rotating shaft 352 passes through the first hole 341 from the top of the first hole 341 and enters into the first connecting hole 353 located at the bottom of the first hole 341. The first rotating shaft 352 can rotate in the first hole 341. The fit between the first rotating shaft 352 and the first connecting hole 353 can be an interference fit, a transition fit, a clearance fit, or a threaded connection fit. From the perspective of the stability of the rotation of the first rotating part 33 and the convenience of disassembly, the threaded connection fit is preferred. The fit between the first rotating shaft 352 and the first hole 341 is a clearance fit, such as the eighth-level clearance fit or the ninth-level clearance fit in the mechanical design standard.

[0043] Therefore, the second frame portion 321 is actually embedded in the first hole portion 341 of the third frame portion 312 through the first rotating shaft 352 of the first rotating portion 35, so as to realize the connection between the second frame portion 321 and the third frame portion 312. In order to limit the vertical movement of the second frame portion 321 relative to the first frame portion 311 when the display screen frame 2 has not yet installed the display screen 1, the end of the first rotating shaft 352 can be provided with a limiting portion 352a whose outer diameter is larger than the first hole portion 341, that is, the first rotating shaft 352 can be integrally processed into a stepped shape, and along the axial direction of the first rotating shaft 352, a limiting portion located at one end of the first rotating shaft 352, a matching portion 352b located at the middle of the first rotating shaft 352, the matching portion rotates relative to the first hole portion 341, and a threaded locking portion 352c located at the other end of the first rotating shaft 352 is locked with the first connecting hole 353.

[0044] In order to reduce the wear of the first rotating member 351 when the rotating frame portion 32 rotates relative to the fixed frame portion 31, and at the same time, in order to reduce the jamming and rotation noise when the rotating frame portion 32 rotates, the first rotating member 351 is provided with a first supporting portion 351c protruding around the opening of the first connecting hole 353, and the rotating frame portion 32 (herein, the second frame portion 321) contacts with the fixed frame portion 31 (herein, the third frame portion 312) through the first supporting portion 351c and supports the fixed frame portion 31 or is supported by the fixed frame portion 31. Therefore, in this embodiment, when the second frame portion 321 rotates relative to the first frame portion 311, the first supporting portion 351c rotates and slides on the third frame portion 312. Since the area supported by the first supporting portion 351c and the third frame portion 312 is relatively small relative to the entire first rotating member 351, the wear of the first rotating member 351 can be reduced, and at the same time, the jamming and rotation noise when the second frame portion 321 rotates can be reduced. Of course, the first supporting portion 351c can also be replaced by a washer.

[0045] In another embodiment of the first rotating portion 33, the first hole portion 341 may also be a threaded hole, and the first connecting hole 353 may be a pin shaft. The first rotating shaft 352 is locked into the first hole portion 341 from above the first hole portion 341, and passes downward from the first hole portion 341 and is inserted into the first connecting hole 353. The first rotating shaft 352 and the first connecting hole 353 are clearance-matched.

[0046] Furthermore, in order to ensure the fixation of the rotating frame portion 32 (such as the second frame portion 321) when the display screen frame 2 is closed, and to prevent it from rotating freely relative to the fixed frame portion 31 (such as the third frame portion 312). The first rotating portion 35 also includes a first latch portion 354, and correspondingly, the third frame portion 312 is provided with a second hole portion 342 opening toward the first rotating portion 35. When the first latch portion 354 is inserted into the second hole portion 342, the rotating frame portion 32 is fixed relative to the fixed frame portion 31, and when the second latch portion is disengaged from the second hole portion 342, the rotating frame portion 32 can rotate relative to the fixed frame portion 31.

[0047] In order to make the first rotating part 35 more compact and reduce the cost, preferably, the first latch part 354 includes a first insertion shaft 354a, a first spring 354a and a spring locking block 354c, the first spring is embedded on the outer periphery of the first insertion shaft 354a, and the spring locking block 354c is locked on the first insertion shaft 354a to fix the first spring 354a. The first rotating member 351 is provided with a third hole 351a and a first stopper 351b. When the display screen frame 2 is closed, the third hole 351a is coaxial with the second hole 342, one axial side of the third hole 351a is adjacent to the second hole 342, and the other axial side of the third hole 351a is adjacent to the second hole 342. The first insertion shaft 354a is L-shaped, and one end of the first insertion shaft 354a, the first spring 354b, and the spring locking block 354c can be accommodated in the third hole portion 351a, and the other end of the first insertion shaft 354a passes through the third hole portion 351a and can be clamped on the first stopper 351b. Under the action of the first spring 354b, when one end of the first insertion shaft 354a extends out of the third hole portion 351a, it can be inserted into the second hole portion 342, and when the first insertion shaft 354a overcomes the compression force of the first spring 354b and retracts into the third hole portion 351a, its other end is clamped on the first stopper 351b.

[0048] By directly machining the third hole 351a that matches the first insertion shaft 354a on the first rotating member 351, the first rotating part 35 can be made more compact, and at the same time, the number of assembled parts is reduced during mass production, thereby reducing costs. In addition, the first latch portion 354 can be integrally planned according to the actual structure of the first rotating part 35, so that the overall design of the first rotating part 33 can be more coordinated and beautiful. In addition, the use of the first spring 354b is only a preferred solution to assist the extension of the first insertion shaft 354a. In fact, the function of the first latch portion 354 can be completed without the spring as long as there is the first insertion shaft 354a.

[0049] Of course, the first latch portion 354 may also use an existing well-known latch, which, as an existing integral latch, may be installed on the first rotating member 351 or on the main frame member 3 a of the second frame portion 321 .

[0050] Figure 7 is a three-dimensional schematic diagram of a seamless spliced ​​display screen 5 formed by splicing display screen components 4. Figure 8 yes Figure 7 A partial enlarged view of point B. Fig. 9 Schematic diagram of the splicing method of the display screen 1. Figure 7-Figure 9 The following describes how to install the display screen 1 to the display screen frame 2, assemble the display screen assembly 4, and assemble the display screen assembly 4 into a seamless spliced ​​display screen 5.

[0051] When there is only one display screen 1, the display screen 1 can be locked to the fixed frame portion 31, that is, locked to the first frame portion 311 and the third frame portion 312, and the rotating frame portion 32 is rotated, that is, the second frame portion 321 and the fourth frame portion 322 are rotated respectively, so that the display screen frame 2 is closed, and the first latch portion 354 is inserted into the second hole portion 342. At this time, the display screen 1 is accommodated in the display screen frame 2, forming a display screen assembly 4 with only one display screen 1. The display screen assembly 4 is particularly suitable for use as a portable advertising screen on the street.

[0052] In addition, since the second frame portion 321 and the fourth frame portion 322 are not directly connected to the display screen 1 by screws, in order to prevent a gap from appearing directly between the second frame portion 321 and the display screen 1, a plurality of first adsorption components 11 may be provided on the display screen 1 on one side adjacent to the second frame portion 321 and the fourth frame portion 322, such as a plurality of first magnets or first iron sheets are locked on the display screen 1, and a plurality of second adsorption components 323 adsorbed by the first adsorption components 11 are provided on the second frame portion 321 and the fourth frame portion 322, such as a plurality of second iron sheets or a second magnet with a polarity opposite to that of the first magnet are locked on the second frame portion 321. When the display screen frame 2 is closed, the first adsorption components 11 are respectively fitted with the second adsorption components 323, thereby achieving no gap between the second frame portion 321 and the fourth frame portion 322 and the display screen 1 even without using screws, and facilitating the rotation of the second frame portion 321 and the fourth frame portion 322 relative to the first frame portion 311 and the third frame portion 312, respectively.

[0053] When the second frame portion 321 and the fourth frame portion 322 are rotated relative to the first frame portion 311 and the third frame portion 312 respectively, so that the display screen frame 2 is opened at the second frame portion 321 and the fourth frame portion 322, the display screen 1 is exposed outside the display screen frame 2 at the second frame portion 321 and the fourth frame portion 322 respectively. At this time, the single display screen assemblies 4 can be spliced ​​to form a seamless spliced ​​display screen 5.

[0054] The seamless spliced ​​display screen 5 can be formed by splicing at least two display screen assemblies 4. Specifically, a first locking portion 51 is provided between the two display screens 1, the two display screens 1 are spliced ​​by the first locking portion 51, and the second frame portions 321 of the two display screen assemblies 4 are respectively rotated to the back of the display screen 1.

[0055] The first locking part 51 may include a first locking rod 511 disposed on one of the display screens 1 and a second locking rod 512 disposed on the other display screen 1. The first locking rod is provided with a hook 513, and the second locking rod is provided with a clamping shaft 514.
