Description

Technical Field

[0001] This utility model relates to the field of display screen protection technology, specifically a display screen protection structure. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels. It is a display method that controls semiconductor light-emitting diodes. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes, which can be used as indicator lights in circuits and instruments, or to form text or number displays.

[0003] For example, utility model patent CN222750709U discloses a collision-resistant display screen, including a housing. The display screen body is placed inside the housing. A baffle is fixedly connected inside the housing and below the display screen body. A fixing mechanism is provided inside the housing and below the baffle. The fixing mechanism includes a motor. Two clearance grooves are formed inside the baffle, and clamps are slidably connected inside the clearance grooves. The beneficial effect of this utility model is that by placing the display screen body inside a first buffer pad and then starting the motor, the output end of the motor drives the gear to rotate. Then, through the meshing between the gear and the two racks, the collision-resistant display screen body is protected. Two racks drive two clamps to move closer together, so that the two protective pads firmly fix the two sides of the display body, preventing the display body from shaking during transportation. This method is more automated, requires no manual installation, and is more convenient to operate. However, if the display is placed in the housing and is only limited by the clamps and protective pads on both sides, the display may still shift during transportation if the front and rear sides of the housing containing the display are not limited. This can cause the sides of the display to slide relative to the protective pads, resulting in poor fixing effect of the fixing mechanism and mediocre protection effect of the display. Therefore, we propose a display protection structure. Utility Model Content

[0026] Specifically, the display body 5 can be placed between the two sets of display self-weight protection components 44 inside the housing 1. The lower end of the display body 5 contacts the display support component 445. At this time, due to the self-weight of the display body 5, the display body 5 drives the L-shaped displacement bar 444 to move downward. The L-shaped displacement bar 444 drives the main wedge block 446 to move downward. The main wedge block 446 reduces the squeezing action on the secondary wedge block 447. At this time, the two symmetrical secondary wedge blocks 447 move closer to each other. The secondary wedge blocks 447 drive the C-shaped guide column 4410 to move, thereby driving their respective surface protective pads 4412 to move closer to the display body 5.

[0027] In this embodiment, the display screen support assembly 445 includes an L-shaped support block 4451. The upper end of the L-shaped support block 4451 is provided with a support groove 4452. The inner wall of the support groove 4452 is rotatably connected by a plurality of uniformly distributed follower shafts 4453 through bearings. Each follower shaft 4453 is fixedly installed with a support roller 4454 at its outer end.

[0028] Specifically, the display support component 445 can support the bottom of the display body 5, and ensures that when the display support component 445 moves, there will be no hard friction between the display body 5 and the display support component 445, thus reducing damage to the bottom of the display body 5.

[0029] In this embodiment, a stepper motor 41 is fixedly installed on the right side of the outer end of the housing 1. A rotating rod 42 is fixedly installed on the output end of the stepper motor 41. Two symmetrically arranged moving blocks 43 are threadedly connected to the outer end of the rotating rod 42, and the outer end of the moving blocks 43 is slidably connected to the slide groove 2. A moving strip 441 is fixedly installed on the upper end of each moving block 43.

[0030] Specifically, the stepper motor 41 is started, and the output end of the stepper motor 41 drives the rotating rod 42 to rotate. The rotating rod 42 drives two symmetrically arranged moving blocks 43 to move closer to each other or further away from each other. Each moving block 43 drives the moving bar 441 to move closer to each other or further away from each other.

[0031] In this embodiment, the door assembly 3 includes a door body 31, a hinged housing 1 at the inner end of the door body 31, an inner protective pad 32 fixedly installed at the middle of the inner end of the door body 31, and a handle 33 fixedly installed at the side end of the door body 31.

[0032] Specifically, the door assembly 3 can perform external protection of the display screen body 5 inside the housing 1.

[0033] In this embodiment, the main wedge block 446 is fixedly installed on the upper end of the spring 4411, and the spring 4411 is sleeved with the movable column 4413.

[0034] Specifically, ensure that the spring 4411 does not interfere with the moving column 4413 during its movement.

[0035] In this embodiment, a surface protective pad 4412 is fixedly installed on the inner end of each C-shaped guide post 4410.

[0036] Specifically, the surface protective pad 4412 can be used to press the front and back ends of the display screen together.

[0037] In this embodiment, two symmetrically arranged threaded grooves are provided at the outer end of the rotating rod 42, and the end of the rotating rod 42 away from the stepper motor 41 is rotatably connected to the housing 1 through a bearing.

[0038] Specifically, ensure that the rotating rod 42 does not interfere with each other during rotation.

[0039] Working principle: In use, the cabinet door 31 can be opened through the handle 33. At this time, the display body 5 is placed between the two sets of display self-weight protection components 44 inside the housing 1. Next, the stepper motor 41 is started. The output end of the stepper motor 41 drives the rotating rod 42 to rotate. The rotating rod 42 drives the two symmetrically arranged moving blocks 43 to move closer or further apart. Each moving block 43 drives the moving strip 441 to move closer or further apart. When the lower end of the display body 5 contacts the display support component 445, due to the weight of the display body 5, the display body 5 drives the L-shaped displacement strip 444 to move downward. At this time, the L-shaped displacement strip 444 drives the main wedge block 446 to move downward. The main wedge block 446 reduces the squeezing action on the secondary wedge block 447. At this time, the two symmetrical secondary wedge blocks 447 move closer to each other. The secondary wedge blocks 447 drive the C-shaped guide column 4410 to move, thereby driving their respective surface protective pads 4412 to approach and abut against the display body 5.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
