Description

Technical Field

[0001] This utility model relates to the field of protection device technology, and more specifically, it relates to a liquid crystal display screen protection device. Background Technology

[0002] In the existing technology, the existing device has obvious defects in structural design, especially the lack of a dedicated component to fully protect the corners of the display screen. Due to its special geometric structure, the corner area of ​​the display screen becomes the weakest part most vulnerable to damage when subjected to external impact. In actual use scenarios, whether it is an accidental collision in an industrial environment or a slight bump in daily operation, it is very easy to cause cracks or damage to the corners.

[0003] Secondly, existing devices suffer from complex operation and low efficiency in replacing corner protectors. During use, corner protector components may wear, deform or even break due to long-term external force or material aging. In such cases, timely replacement is necessary to maintain good protection. However, existing corner protector components usually adopt complex fixing structures, and the disassembly process is cumbersome.

[0004] Finally, the existing device has obvious shortcomings in the design of the fixing mechanism between the display screen and the corner protector. The ideal fixing method should not only ensure that the corner protector fits tightly with the display screen and provides a stable and reliable protection effect, but also allow for convenient and quick disassembly when needed. However, the fixing methods commonly used in the prior art are either too loose, causing the corner protector to easily shift during use. Utility Model Content

[0030] Please see Figures 1-5 A liquid crystal display screen protection device includes a mounting plate 1, on which a protection component is provided. The protection component includes an outer frame 2 and a screen body 3. The outer frame 2 is disposed on the mounting plate 1, and the screen body 3 is disposed inside the outer frame 2. A connecting plate 4 is detachably mounted on the mounting plate 1. Corner guards 5 are connected to the connecting plate 4, which causes the corner guards 5 to be tightly attached to the four corners of the outer frame 2. A wiring port 6 is installed on one side of the mounting plate 1. A disassembly assembly is provided between the connecting plate 4 and the mounting plate 1. The disassembly assembly includes a mounting sleeve 7 and a stabilizing rod 8. The mounting sleeve 7 is fitted to one side of the mounting plate 1, and the stabilizing rod 8 is detachably mounted on the mounting sleeve 7. The stabilizing rod 8 is slidably connected to the connecting plate 4 and the mounting plate 1. A stabilizing plate 9 is connected to one end of the stabilizing rod 8, and the stabilizing plate 9 is tightly attached to the connecting plate 4.

[0031] The mounting sleeve 7 is rotatably connected to a drive gear 10, and a fixing plate 11 is mounted on the mounting sleeve 7.

[0032] A driven gear 12 is rotatably connected to the fixed plate 11, and a threaded rod 13 is connected to the driven gear 12. The driving gear 10 is meshed with the driven gear 12.

[0033] A control block 14 is installed on the mounting sleeve 7, and an adjusting sleeve 15 is slidably connected to the control block 14. The adjusting sleeve 15 is threadedly connected to the threaded rod 13.

[0034] In this embodiment, the external power cord is inserted into the wiring port 6 at one end of the mounting plate 1 to connect the screen 3 to power, making it easy to use the screen 3. Corner protectors 5 are placed at the four corners of the outer frame 2 of the screen 3 to protect the four corners. When the screen 3 is moved to a suitable position, the corner protectors 5 need to be removed to facilitate the installation of the screen 3. The drive gear 10 is rotated along the mounting sleeve 7, so that the driven gear 12 meshing with the drive gear 10 is rotated, so that the threaded rod 13 is rotated. When the threaded rod 13 rotates, the adjusting sleeve 15 threadedly connected to the threaded rod 13 slides along the control block 14. As the adjusting sleeve 15 moves continuously, the obstruction of the rotating plate 21 is released.

[0035] Please see Figure 2-5 As an embodiment of a liquid crystal display screen protection device for locking components: a locking component is provided on the mounting sleeve 7. The locking component includes an insertion rod 16 and an insertion block 17. The insertion rod 16 is slidably connected to the mounting sleeve 7. The insertion block 17 is connected to one end of the insertion rod 16. An insertion groove 18 is provided on the stabilizing rod 8. The insertion groove 18 is adapted to the insertion block 17.

[0036] One end of the insertion rod 16 is connected to an abutment block 19.

[0037] A second spring 20 is fitted onto the insertion rod 16.

[0038] The two ends of the second spring 20 are connected to the abutment block 19 and the mounting sleeve 7. A rotating plate 21 is rotatably connected to the mounting sleeve 7, and a first spring 22 is connected between the mounting sleeve 7 and the rotating plate 21.

[0039] More specifically, when the abutment on the rotating plate 21 is released, the compression on the first spring 22 is released. Under the action of the elastic potential energy of the first spring 22, the rotating plate 21 is moved to rotate along the mounting sleeve 7. When the rotating plate 21 rotates, the abutment on the abutment block 19 is released, and the compression on the second spring 20 is released. Under the action of the elastic potential energy of the second spring 20, the insertion rod 16 at one end of the abutment block 19 is moved to slide along the mounting sleeve 7, and the insertion block 17 on the insertion rod 16 is moved out of the insertion slot 18 of the stabilizing rod 8, thereby releasing the fixation on the stabilizing rod 8. Then, the stabilizing rod 8 is slid out along the mounting sleeve 7, the mounting plate 1, and the connecting plate 4, so that the corner protector 5 can be removed from the mounting sleeve 7, allowing for the subsequent installation of the screen body 3.

[0040] In summary, when using or running the entire device: insert the external power cord into the wiring port 6 at one end of the mounting plate 1 to connect the screen 3 to power, making it easy to use the screen 3. By attaching corner protectors 5 to the four corners of the outer frame 2 of the screen 3, the four corners are protected. When moving the screen 3 to a suitable position, the corner protectors 5 need to be removed to facilitate the installation of the screen 3. When the drive gear 10 rotates along the mounting sleeve 7, the driven gear 12 meshing with the drive gear 10 will rotate, causing the threaded rod 13 to rotate. When the threaded rod 13 rotates, the adjusting sleeve 15 threadedly connected to the threaded rod 13 will slide along the control block 14. As the adjusting sleeve 15 moves continuously, the obstruction of the rotating plate 21 is released.

[0041] When the abutment on the rotating plate 21 is released, the compression of the first spring 22 is released. Under the action of the elastic potential energy of the first spring 22, the rotating plate 21 is moved to rotate along the mounting sleeve 7. When the rotating plate 21 rotates, the abutment on the abutment block 19 is released, and the compression of the second spring 20 is released. Under the action of the elastic potential energy of the second spring 20, the insertion rod 16 at one end of the abutment block 19 is moved to slide along the mounting sleeve 7, and the insertion block 17 on the insertion rod 16 is moved out of the insertion slot 18 of the stabilizing rod 8, thereby releasing the fixation of the stabilizing rod 8. Then, the stabilizing rod 8 is slid out along the mounting sleeve 7, the mounting plate 1, and the connecting plate 4, so that the corner protector 5 can be removed from the mounting sleeve 7, allowing for the subsequent installation of the screen body 3.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
