Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an anti-deformation device for installing an LED display screen. Background Art

[0002] A display screen is a flat panel display composed of small LED display module panels, which is used to display various information such as text, images, videos, and video signals. Due to the good area scalability of spliced ​​display screens, they are often used in outdoor media, exhibition halls, squares, performance venues, monitoring facilities, etc. for public viewing.

[0003] Traditional display screens are assembled, usually by assembling multiple display modules together, and adjacent display modules are fixed by bolts; however, this type of fixation has the following two defects: first, with the long-term use of the display screen, the bolts are prone to loosening, resulting in the display screen being not firmly fixed, and prone to misalignment or deformation; second, since each display screen needs to be fixed with multiple bolts, if multiple display screens are assembled, the assembly efficiency is slow and the labor workload is relatively large.

[0004] Therefore, we propose an anti-deformation device for installing an LED display screen to solve the above-mentioned problems. Utility Model Content

[0007] Further: the slideways at both ends are in an "L" shape.

[0008] Further: the middle chute is in a "T" shape.

[0009] Further: the locking assembly includes a fixed seat slidably installed in the installation groove and a baffle installed in the fixed seat for up and down sliding, and the bottom end of the baffle is connected to the inner bottom wall of the fixed seat through a spring.

[0010] Furthermore: the assembled display screen includes a display screen body and a back cover installed on the back of the display screen body, and every two sliding rods are symmetrically installed at the ends of the back cover.

[0011] Further: a rotating seat is installed on each of the two mounting rods, and the two rotating seats are installed with the same "U"-shaped mounting frame through a rotating column, and the "U"-shaped mounting frame is installed with a mounting hole.

[0012] Furthermore: an arc groove coaxial with the rotating column is opened on the rotating seat, a through hole corresponding to the arc groove is installed at the end of the "U"-shaped mounting frame, and a fixing bolt is installed in the through hole, and one end of the fixing bolt passes through the through hole and the arc groove in turn and is threaded with a butterfly nut.

[0013] Beneficial effects of the utility model:

[0014] The utility model is provided with a slide groove on the mounting rod and a slide rod is installed on the back of the display screen body. The display screen body is slidably installed in the mounting rod through the slide rod, thereby playing a role of limiting the left and right positions of the display screen body, reducing the left and right looseness of the display screen; a locking component is installed at the end of the mounting rod, and if multiple display screens are installed in the slide groove, the slide groove can be blocked by the locking component, playing a role of limiting the upper and lower positions of the display screens, reducing the up and down shaking of the display screens.

The top of the mounting rod 101 is provided with a mounting groove 3 connected to the slide groove 103, and the side of the mounting rod 101 is provided with a square hole connected to the mounting groove 3. A locking component 4 is installed inside the mounting groove 3. Through the setting of the locking component 4, the slide rod 21 is limited to prevent the slide rod 21 from sliding up and down.

[0030] The assembled display screen 2 includes a display screen body 22, a rear cover 23 is fixed to the back of the display screen body 22 by bolts, and sliding rods 21 are fixed to both ends of the rear cover 23, and the two sliding rods 21 are arranged parallel to each other, so that the assembled display screen 2 can be slidably installed on the mounting rod 101 through the sliding rods 21.

[0031] Specifically, the locking assembly 4 includes a "hollow" fixing seat 41, and a rectangular hole communicating with the interior is opened on the top of the fixing seat 41, and the lower part of the baffle 42 extends through the rectangular hole to the top of the fixing seat 41, and the bottom of the baffle 42 is connected to the inner bottom wall of the fixing seat 41 through a plurality of springs 43. Through the setting of the springs 43, the baffle 42 is pressed down to play a reset role, and extension plates 44 are fixed on the four sides of the bottom of the baffle 42. Through the setting of the extension plates 44, the baffle 42 is limited to prevent it from detaching from the fixing seat 41. In the initial state, the top surface of the baffle 42 is higher than the top surface of the fixing seat 41. In the pressure state, the top surface of the baffle 42 and the top surface of the fixing seat 41 are located on the same plane. Through the setting of the locking assembly 4, a plurality of sliding rods 21 are fixed.

[0032] A rotating seat 5 is installed on each of the two mounting rods 101, and the two rotating seats 5 are located on the same plane. A "U"-shaped mounting frame 7 is arranged between the two rotating seats 5, and both ends of the "U"-shaped mounting frame 7 are rotatably connected to the rotating seat 5 through a rotating column 6. Through the setting of the "U"-shaped mounting frame 7, the mounting frame 1 can be rotated and adjusted, thereby changing the inclination angle of the display screen.
