The fixing seats 4 are in an "L" shape, and a base 5 is provided at the bottom of the fixing seat 4. The base 5 is inserted into the interior of the installation channel 2 and can be displaced horizontally along the installation channel 2;

[0031] According to the area where the display screen needs to be installed, according to the installation position, installation holes are drilled in the wall in advance and expansion bolts are installed, and then they are connected to the fixing hole positions at both ends of the cross frame 1 to achieve the installation of the cross frame 1. The lower cross frame 1 and the upper cross frame 1 are arranged at intervals. Then, the fixing seat 4 and the display screen body 3 are fixed by screws. The display screen body 3 is carried to the upper part of the cross frame 1, and the base 5 and the fixing seat 4 are connected to the installation channel 2, horizontally adjusted to the designated position, and the remaining display screen bodies 3 are installed and spliced in sequence to achieve the overall installation and fixation. The operation is simple, and it can be completed by a single person, saving the labor installation cost, and the operation difficulty is relatively low, reducing the requirements for the experience of construction workers.

[0032] Preferred embodiment, combining Figure 3As shown, the installation channel 2 includes a slideway 201 and an access port 202; the slideway 201 is opened along the length direction of the cross frame 1 and is rectangular as a whole in a top view, while the access ports 202 are used in pairs, with two in each group, and two groups are arranged at both ends of the slideway 201 respectively, facilitating the installation operation of the display screen body from both ends. At the same time, the access port 202 is in a communicating state with the slideway 201, and is connected by a rectangular notch, and the width dimension of the access port 202 is greater than the width dimension of the slideway 201. The width of the base 5 is equal to the width of the access port 202. After the base is inserted, the fixing seat 4 is pushed into the slideway 201 from the notch and adjusted horizontally, so as to realize the installation and fixation of the display screen body 3. The operation is simple and convenient, and the fixation is reliable.

[0033] In a preferred embodiment, combined with Figure 2 As shown, a pressing component 6 is provided behind the cross frame 1.

[0034] In a preferred embodiment, combined with Figure 5 and Figure 6 As shown, the pressing component 6 includes a pressing plate 7 and a spring 8; sliding rods 701 are symmetrically welded on both sides of the pressing plate 7. Through holes are processed behind the cross frame 1, and the sliding connection is formed by inserting the sliding rods 701 into the through holes. At the same time, the spring 8 is sleeved on the sliding rods 701 and contacts the pressing plate 7 and the cross frame 1 at both ends respectively. The elastic force of the spring 8 is used to push the pressing plate 7 to keep contacting the base 5, and it does not affect the displacement adjustment of the fixing seat 4.

[0035] In a preferred embodiment, combined with Figure 7 As shown, a friction layer 702 is provided on the surface of the pressing plate 7. The friction layer 702 is made of rubber material, such as natural rubber, which can effectively increase the frictional force after contacting the base 5 and improve the positioning stability.

[0036] In a preferred embodiment, combined with Figure 7 As shown, a plurality of anti-slip lines 501 are provided on the base 5. The cross-sectional shape of the anti-slip lines 501 is semi-circular. By contacting the friction layer 702, under the elastic force of the spring 8, the anti-slip lines 501 can be pressed into the friction layer 702, further enhancing the braking effect. Specific embodiment two

[0038] Combined with Figure 3-5 As shown, braking teeth 703 are provided on both the pressing plate 7 and the base 5. The cross-sectional shape of the braking teeth 703 is triangular. By meshing connection between the two, the stability after positioning can also be improved, and when the fixing seat 4 is pushed to displace, it can be realized by compressing the spring 8.

The fixed shafts 101 are rotationally connected to the cross frame 1. A disk 102 in contact with the pressing plate 7 is provided at the end of the fixed shaft 101, and a plane is provided on the outer circle of the disk 102, forming a structure of an incomplete disk 102. The diameter of the disk 102 is equal to the distance between the left side of the pressing plate 7 and the inner wall of the cross frame 1. When the outer circle of the disk 102 is simultaneously in contact with the inner wall of the cross frame 1 and the left side of the pressing plate 7, the support and locking of the pressing plate 7 can be achieved. At this time, in cooperation with the braking tooth 703 structure, the complete locking of the fixed seat 4 can be achieved. When the plane of the disk 102 is rotated to be parallel to the left side of the pressing plate 7, a certain displacement distance can be reserved to achieve the lateral adjustment of the fixed seat 4.

[0040] Preferred embodiment, combined with Figure 6 As shown, an indicating needle 103 is provided at the left end of the fixed shaft 101 to facilitate judging the position of the plane during adjustment. Specific embodiment three

[0042] Combined with Figure 4 and Figure 7 As shown, the base 5 is integrally in an "L" - shaped structure. The overall stress strength can be enhanced by adding a trapezoidal reinforcing plate at the bending part, improving the support for the display screen body 3.
