The elastic gasket 42 may be sleeved on the threaded column, and the elastic gasket 42 may elastically abut against the second fixing portion 43 of the adjacent fixing rod 4. When the fixing rod 4 needs to be disassembled, the fixing rod 4 is rotated so that the elastic gasket 42 is squeezed, so that the elastic buffer of the elastic gasket 42 is utilized, so that the second fixing portion 43 of the fixing rod 4 can be separated from the first fixing portion 41 of another fixing rod 4 adjacent thereto, and the buffer of the elastic gasket 42 ensures that the other fixing rods 4 do not loosen.

[0067] It should be noted that the elastic gasket 42 can be a structural member formed of rubber or other materials with a certain elastic deformation capability; the elastic gasket 42 can also be a structural member formed of a spring or other structural design with a certain elastic deformation capability.

[0068] See also Fig. 9 As shown, in some embodiments, the guide member 3 may be trumpet-shaped. A large port and a small port may be provided on the guide member 3.

[0080] In some embodiments, the module connecting plate 22 may be provided with a positioning post. The positioning post may protrude and extend from the module connecting plate 22 toward the box body 1. The box body 1 may be provided with a positioning groove. The positioning groove may be provided corresponding to the positioning post. When the display module 2 is installed on one side of the box body 1, the positioning post on the module connecting plate 22 can extend into and be limited in the positioning groove of the box body 1, and then the box body 1 and the display module 2 can be positioned by the positioning post and the positioning groove.

[0081] In some embodiments, there may be multiple positioning posts. Multiple positioning posts may be arranged at intervals on the module connecting plate 22. There may also be multiple positioning grooves. Multiple positioning grooves may be arranged one-to-one with multiple positioning posts. When the display module 2 is installed on one side of the box 1, multiple positioning posts on the module connecting plate 22 can simultaneously extend into and be limited in multiple positioning grooves of the box 1, thereby further improving the accuracy of installation between the box 1 and the display module 2.

[0082] In some embodiments, two positioning posts may be provided. The two positioning posts may be arranged diagonally. Two positioning slots may be provided. The two positioning slots may be arranged diagonally. Thus, the accuracy of installation between the box 1 and the display module 2 can be further improved by using the positioning posts and positioning slots arranged diagonally.

[0083] In some embodiments, the positioning column and the module connecting plate 22 may be connected by bolts, thereby improving the connection stability between the positioning column and the module connecting plate 22 .

[0084] In some embodiments, a power cover may be provided in the display screen 100. The power cover may be covered on the box body 1. A hinge and buckle design may be adopted between the power cover and the box body 1, so that the power cover can be easily opened and closed relative to the box body 1, thereby quickly completing the installation of the power supply and the corresponding electrical appliances and subsequent maintenance.

[0085] In some embodiments, the power supply may be disposed in the box 1. Heat dissipation ribs may be provided on the outer wall of the box 1, and the heat dissipation ribs on the box 1 may be used to increase the heat dissipation area of ​​the power supply, thereby enhancing the heat conduction and heat dissipation capacity of the power supply.

[0086] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0087] The present invention provides a display screen 100, including a plurality of display units 10 arranged in a spliced ​​manner, each display unit 10 including a box body 1 and a display module 2 arranged on the box body 1, and a connecting hole is arranged on the box body 1. A plurality of guide members 3 are arranged on the display module 2 in a one-to-one correspondence, and each guide member 3 is provided with a guide hole 31, and the guide hole 31 is arranged correspondingly to the connecting hole. A plurality of fixing rods 4 are arranged on the plurality of display units 10 in a one-to-one correspondence. Each fixing rod 4 is inserted into the guide hole 31 and the connecting hole on the corresponding display module 2; when the plurality of display units 10 are spliced ​​and connected, the fixing rods 4 on the plurality of display units 10 arranged along the extending direction of the fixing rods 4 are connected end to end in sequence. Thus, by using the corresponding arrangement of the connecting hole on the box body 1 and the guide hole 31 of the guide member 3 on the display module 2, the fixing rod 4 passes through the guide hole 31 and the connecting hole, so that the fixing rod 4 can realize the fixed connection between the box body 1 and the display module 2, thereby preventing the display module 2 from loosening with the box body 1. A plurality of fixing rods 4 are connected end to end so that when a plurality of display units 10 are spliced ​​and connected, a plurality of boxes 1 and a plurality of display modules 2 form a whole, thereby further improving the connection stability between the display module 2 and the box 1, ensuring the reliability of the structure when the display screen 100 is working, and improving the wind resistance and earthquake resistance of the entire display screen 100.

[0088] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
