[0022] The technical solution of the utility model is further described below in conjunction with specific implementation methods: Example 1

[0023] A double-sided LCD screen frame, used to package two screens, such as Figure 1 As shown, it includes a first profile 1, a second profile 2, a third profile 3 and a fourth profile 4; the two display screens are a first display screen 6 and a second display screen 7, and the first display screen 6 and the second display screen 7 have the same structure and are display components including a liquid crystal panel.

[0024] The second profile 2 and the third profile 3 are symmetrically mounted on both sides of the first profile 1, and the second profile 2 and the third profile 3 are respectively assembled and connected with the first profile 1; a clamping space for clamping the first display screen 6 is formed between the first profile 1 and the second profile 2, and a clamping space for clamping the second display screen 7 is formed between the first profile 1 and the third profile 3;

[0025] The fourth profile 4 is assembled and connected to the first profile 1. The fourth profile 4 is arranged on the outer side of the first profile 1 close to the frame in the width direction. After the fourth profile 4 is assembled and connected to the first profile 1, the fourth profile 4 abuts against the outer side of the second profile 2 and the third profile 3 in the width direction to limit the first profile 1 and the second profile 2.

[0026] More specifically, Figure 2 and Figure 3 As shown, the first profile 1 has a support plate 11 supported between the first display screen 6 and the second display screen 7, and a connecting head 12 arranged on one side of the support plate 11; the second profile 2, the third profile 3 and the fourth profile 4 are respectively assembled and connected with the connecting head 12, and the second profile 2 and the third profile 3 form a clamping space with the support plate 11 respectively, and the extension width of the support plate 11 in the clamping space area is greater than the extension width of the second profile 2 and the third profile 3.

[0027] Preferably, the support plate 11 is only supported on the edge area of ​​the display screen, and a hollow space is formed between the two display screens near the middle of the display screens, which can reduce the overall weight.

[0028] In order to realize the assembly and installation of the fourth profile 4, the connecting head 12 is provided with a first card slot 14 in the middle part of the opposite side of the support plate 11, and the side of the fourth profile 4 that is in contact with the connecting head 12 is provided with a first card block 41 that matches the first card slot 14 corresponding to the first card slot 14, and the assembly connection between the fourth profile 4 and the first profile 1 is realized by the mutual engagement of the first card block 41 and the first card slot 14. After the fourth profile 4 is assembled and connected with the first profile, the side of the fourth profile 4 with the first card block 41 is in contact with the connecting head 12, and the second profile 2 and the third profile 3 are arranged close to the outer side of the display screen, thereby realizing the limitation of the second profile 2 and the third profile 3.

[0029] In order to realize the assembled installation of the second profile 2 and the third profile 3 , the connector 12 is provided with second slots 13 corresponding to the second profile 2 and the third profile 3 , respectively. The third slots 13 are symmetrically arranged on both sides of the first slot 14 .

[0030] Correspondingly, the second profile 2 and the third profile 3 are respectively provided with a second clamping block 21 and a third clamping block 31 that cooperate with the second clamping slot 13. The second profile 2 is assembled with the first profile 1 by the second clamping block 21 and the second clamping slot 13 being interlocked with each other, and the third profile 3 is assembled with the first profile 1 by the third clamping block 31 and the second clamping slot 13 being interlocked with each other.

[0031] The first card slot 14 extends along the length direction of the first profile 1, and the first card slot 14 has an arc-shaped inner wall. The arc surface of the arc-shaped inner wall of the first card slot 14 is a major arc. The first card block 41 is provided with an arc-shaped outer wall corresponding to the arc-shaped inner wall of the first card slot 14. During installation, the first card block 41 is inserted into the first card slot 14 along the end of the first card slot 14.

[0032] The arc-shaped inner wall of the first clamping slot 14 can prevent the first clamping block 41 from being separated from the first clamping slot 14 and facilitate installation.

[0033] The cooperation between the first card slot 14 and the first card block 41, and the cooperation between the second card slot 13 and the second card block 21 and the third card block 31 is more beautiful than fixing with screws, and the deformation of the profile caused by changes in ambient temperature and humidity can be absorbed by the cooperation gap, which is beneficial to prolonging the service life of the display screen.

[0034] When in use, in order to increase the protection of the display screen, buffer pads 5 for supporting the display screen are respectively arranged in the corresponding clamping spaces of the second profile 2 and the third profile 3. The buffer pads 5 are such as common rubber strips, porous sponge structures, etc., and the buffer pads 5 are bonded and fixed to the second profile 2 and the third profile 3.

[0035] Furthermore, the buffer pad 5 includes a buffer pad supported on the front side of the display screen and a buffer pad supported on the side of the display screen.

[0036] Preferably, in the present embodiment, the first profile 1, the second profile 2, the third profile 3 and the fourth profile 4 are formed by extruding metal profiles. The metal extrusion molding process is to extrude the blank profile into the desired shape after applying pressure by extrusion. Common metal blanks such as aluminum, copper, aluminum alloy, copper-aluminum alloy, etc. have relatively low processing costs.

[0037] In actual use, the double-sided display screen frame in this embodiment is set at the opposite sides of the display screen, and the adjacent sides can also adopt the double-sided display screen frame in this embodiment, or can adopt frames of other shapes for packaging. Example 2

[0039] The first profile 1 has a support plate 11 supported between display screens and a connecting head 12 arranged on the thickness side of the support plate; the second profile 2, the third profile 3 and the fourth profile 4 are respectively assembled and connected with the connecting head 12, and the second profile 2 and the third profile 3 respectively form a clamping space with the support plate 12, and the extension length of the support plate 11 in the clamping space area is greater than the extension length of the second profile 2 and the third profile 3.

[0040] More specifically, the second profile 2, the third profile 3 and the fourth profile 4 are respectively flat plate structures, the second profile 2 and the third profile 3 are abutted against the opposite sides of the connecting head 12, the second profile 2 and the third profile 3 are respectively assembled and connected to the connecting head 12 by screws 8, the screws 8 and the connecting head 12 are threadedly matched, and then the fourth profile 4 is assembled and connected to the connecting head 12 by screws 8, the second profile 2 and the third profile 3 are vertically arranged relative to the fourth profile 4, and the edges of the second profile 2 and the third profile 3 are shielded and packaged by the fourth profile 4.
