Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display screen corner protector. Background Technology

[0002] During transportation and handling, the protruding corners of the display screen are easily bumped and impacted, causing damage to the electrical components on the screen. Therefore, protective covers should be used to protect the corners of the display screen when handling it.

[0003] Existing protective cases are generally customized according to the display screen model, and can only be used for specific display screen models. They cannot protect display screens of different thicknesses and sizes, and have poor versatility. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a display screen corner protector, which solves the problem of poor universality of display screen protective sleeves in the existing technology.

[0005] According to an embodiment of this utility model, a display screen corner protector includes a corner protector body and a protective plate spaced apart from the corner protector body. The corner protector body includes a parallel first clamping plate and a mounting plate. The first clamping plate has two connected vertical plates that are perpendicular to each other. Each vertical plate has a movable slider, a damper that cooperates with the slider, and a buffer spring that abuts against the slider. When the slider moves, it approaches or moves away from the connection point of the two vertical plates. The protective plate is right-angled, and two connecting rods are rotatably connected to the side of the protective plate closest to the corner protector body. The ends of the two connecting rods away from the protective plate are rotatably connected to the two sliders respectively. The mounting plate has a movable second clamping plate and a first spring that abuts against the second clamping plate. The second clamping plate is located between the first clamping plate and the mounting plate. The first spring drives the second clamping plate to move closer to the first clamping plate.

[0006] Furthermore, each of the vertical plates is provided with a sliding groove, and the slider is movably disposed within the sliding groove.

[0007] Furthermore, the damper and the buffer spring are respectively disposed in the slide groove, and one end of the buffer spring abuts against the slider and the other end abuts against the inner wall of the slide groove.

[0008] Furthermore, the mounting plate is provided with a guide cylinder, and the second clamping plate is provided with a guide rod that cooperates with the guide cylinder, and the buffer spring is sleeved on the guide rod.

[0009] Furthermore, the guide rod includes a connected head and a rod portion, and the diameter of the head is larger than the diameter of the rod portion. The guide cylinder is provided with a guide hole that mates with the head. A connector is sleeved on the rod portion. The connector has a through hole through which the rod portion passes, and the diameter of the through hole is smaller than the diameter of the head. The connector is threadedly connected to the guide cylinder.

[0010] Furthermore, the end of the rod away from the guide cylinder has a threaded portion, and the second clamping plate is provided with a threaded hole that mates with the threaded portion.

[0011] Furthermore, the vertical plate is provided with positioning plates parallel to the second clamping plate and the positioning plates are provided with slots. The second clamping plate is provided with a rotatable movable rod. A pressure plate and a second spring abutting against the pressure plate are sleeved on the movable rod. The second spring drives the pressure plate to abut against the side of the positioning plate away from the second clamping plate.

[0012] Furthermore, the second clamping plate is provided with two parallel connecting plates spaced apart and a connecting shaft is provided between the two connecting plates. One end of the movable rod has a connecting block and a connecting hole that cooperates with the connecting shaft.

[0013] Furthermore, the second clamping plate is also provided with a buckle plate parallel to the second clamping plate, the buckle plate being located between the second clamping plate and the mounting plate.

[0014] Compared with existing technologies, this utility model has the following advantages: By employing a first clamping plate and a mounting plate parallel to each other on the corner protector body, and a second clamping plate and a first spring that drives the second clamping plate closer to the first clamping plate, the corner protector body is attached to the corner of the display screen, and the display screen is placed between the first and second clamping plates. The elastic force provided by the first spring clamps the display screen between the first and second clamping plates. Furthermore, the movement of the second clamping plate on the mounting plate allows the distance between the first and second clamping plates to be adapted to the thickness of the display screen, thereby securing the corner protector body at the corner of the display screen. The protective plate, which is fixed in position and installed on the corner protector body, protects the corners of the display screen. When the protective plate is impacted by an external force, the protective plate moves relative to the corner protector body, causing the connecting rod to push the slider to move. During the movement of the slider, the damper and buffer spring buffer the impact force on the protective plate and reduce the impact force, preventing the protective plate from colliding with the corner protector body. This avoids damage to the display screen after being subjected to external force. It solves the technical problem of poor universality of existing display screen protective sleeves, and produces a technical effect of being able to be installed on display screens of various thicknesses and sizes with good universality. It is also easy to install and remove and has a good protective effect. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a display screen corner protection device, which is installed at the four corners of the display screen to protect the display screen during handling and transportation, and to prevent damage to the display screen caused by corner impacts.

[0022] Please refer to Figure 1 , Figure 3 and Figure 4The display screen corner protection device includes a corner protection body 1 and a protective plate 2 spaced apart from the corner protection body 1. The corner protection body 1 includes a parallel first clamping plate 11 and a mounting plate 12. The first clamping plate 11 is provided with two connected vertical plates 13, and the two vertical plates 13 are perpendicular to each other. Each vertical plate 13 is provided with a movable slider 3, a damper 15 cooperating with the slider 3, and a buffer spring 4 abutting against the slider 3. When the slider 3 moves, it approaches or moves away from the connection point of the two vertical plates 13. The protective plate 2 is right-angled, and two connecting rods 21 are rotatably connected to the side of the protective plate 2 closest to the corner protection body 1. The ends of the two connecting rods 21 away from the protective plate 2 are rotatably connected to the two sliders 3 one-to-one. When the protective plate 2 is impacted by an external force, the connecting rods 21 push the sliders 3 to move and pass through. The damper 15 and the buffer spring 4 provide buffering to reduce the impact force on the display screen and prevent the protective plate 2 from colliding with the corner protector body 1, thereby protecting the display screen. The mounting plate 12 is provided with a movable second clamping plate 5 and a first spring 6 that abuts against the second clamping plate 5. The second clamping plate 5 is located between the first clamping plate 11 and the mounting plate 12. The first spring 6 drives the second clamping plate 5 to move closer to the first clamping plate 11. The elastic force provided by the first spring 6 causes the first clamping plate 11 and the second clamping plate 5 to abut against the opposite sides of the display screen, thereby installing the display screen corner protector onto the display screen. The movement of the second clamping plate 5 on the mounting plate 12 makes the distance between the first clamping plate 11 and the second clamping plate 5 match the thickness of the display screen.

[0023] Specifically, the installation and removal steps of the display screen corner protector provided in this embodiment are as follows: First, press the second clamping plate 5 to move it away from the first clamping plate 11, then attach the corner protector body 1 to the corner of the display screen. At this time, the display screen is placed between the first clamping plate 11 and the second clamping plate 5. Release the second clamping plate 5 so that it moves closer to the first clamping plate 11 under the push of the first spring 6, and clamp the display screen between the first clamping plate 11 and the second clamping plate 5 by the elastic force provided by the first spring 6. The display screen corner protector can then be installed at the corner of the display screen. The distance between the first clamping plate 11 and the second clamping plate 5 is adapted to the thickness of the display screen by the movement of the second clamping plate 5 on the mounting plate 12. When it is necessary to remove the display screen corner protector, move the second clamping plate 5 away from the first clamping plate 11 to remove the corner protector body 1 from the corner of the display screen. When the protective plate 2 is bumped during the handling and transportation of the display screen, the movement of the protective plate 2 relative to the corner protector body 1 causes the connecting rod 21 to push the slider 3 to move. During the movement of the slider 3, the damper 15 and the buffer spring 4 buffer and reduce the impact force on the protective plate 2, and prevent the protective plate 2 from colliding with the corner protector body 1, thereby avoiding damage to the display screen after being subjected to external force. The display screen corner protector device provided in this embodiment can be installed on display screens of various thicknesses and sizes, has good versatility, and is easy to install and remove with good protective effect.

[0024] like Figure 1 As shown, the vertical plate 13 is provided with a sliding groove 14, and the slider 3 is movably disposed within the sliding groove 14. The sliding groove 14 on the vertical plate 13 guides the slider 3 to move on the vertical plate 13, prevents the slider 3 from deviating from the preset direction when moving, and ensures that the slider 3 and the vertical plate 13 are firmly engaged, preventing the slider 3 from accidentally detaching from the vertical plate 13.

[0025] In this embodiment, the damper 15 and the buffer spring 4 are respectively disposed within the slide groove 14, with one end of the buffer spring 4 abutting against the slider 3 and the other end abutting against the inner wall of the slide groove 14. Distributing the damper 15 and the buffer spring 4 within the slide groove 14 ensures stable engagement between the damper 15 and the buffer spring 4 and the slider 3. Furthermore, the two ends of the buffer spring 4 in the extension / retraction direction abut against the slider 3 and the inner wall of the slide groove 14, respectively, allowing the buffer spring 4 to smoothly extend and retract during the movement of the slider 3.

[0026] Please combine Figure 3 and Figure 4The mounting plate 12 is provided with a guide cylinder 16, and the second clamping plate 5 is provided with a guide rod 51 that cooperates with the guide cylinder 16, and the buffer spring 4 is sleeved on the guide rod 51. The second clamping plate 5 and the mounting plate 12 are connected by the cooperation of the guide rod 51 and the guide cylinder 16, and when the second clamping plate 5 moves relative to the mounting plate 12, the guide rod 51 slides within the guide cylinder 16 to prevent the second clamping plate 5 from deviating unexpectedly.

[0027] In detail, the guide rod 51 includes a connected head 52 and a rod portion 53, with the diameter of the head 52 being larger than the diameter of the rod portion 53. The guide cylinder 16 has a guide hole 17 that mates with the head 52. A connector 54 is fitted onto the rod portion 53. The connector 54 has a through hole through which the rod portion 53 passes, with the diameter of the through hole being smaller than the diameter of the head 52. The connector 54 is threadedly connected to the guide cylinder 16. When the guide rod 51 is inserted into the guide cylinder 16, the rod portion 53 is first passed through the through hole on the connector 54, then the head 52 is inserted into the guide hole 17, and the connector 54 is threadedly connected to the guide cylinder 16. This allows the guide rod 51 to be inserted into the guide cylinder 16 while keeping the head 52 within the guide hole 17. This facilitates the assembly of the display screen corner protector while preventing the guide rod 51 from detaching from the guide cylinder 16 during use.

[0028] like Figure 3 As shown, the end of the rod 53 away from the guide cylinder 16 has a threaded portion, and the second clamping plate 5 has a threaded hole that mates with the threaded portion. The guide rod 51 and the second clamping plate 5 are combined through the engagement of the threaded portion and the threaded hole, ensuring a secure connection between the guide rod 51 and the second clamping plate 5.

[0029] Please refer to Figure 1 and Figure 2The vertical plate 13 is provided with positioning plates 18 parallel to the second clamping plate 5, and the positioning plates 18 are provided with slots 19. The second clamping plate 5 is provided with a rotatable movable rod 7. The movable rod 7 is fitted with a pressure plate 71 and a second spring 72 that abuts against the pressure plate 71. The second spring 72 drives the pressure plate 71 to abut against the side of the positioning plate 18 away from the second clamping plate 5. After the corner protector body 1 is attached to the corner of the display screen and the first clamping plate 11 and the second clamping plate 5 are respectively in contact with the two sides of the display screen, the pressure plate 71 is first moved and the movable rod 7 is rotated so that the movable rod 7 extends into the slot 19. Then the pressure plate 71 is released so that the pressure plate 71 is pressed against the side of the positioning plate 18 away from the second clamping plate 5 under the action of the elastic force provided by the second spring 72. The relative position of the first clamping plate 11 and the second clamping plate 5 can be fixed by the cooperation between the movable rod 7 and the slot 19 and the friction between the pressure plate 71 and the positioning plate 18, so as to prevent the first clamping plate 11 or the second clamping plate 5 from loosening during the transportation of the display screen, which helps to improve the reliability of the display screen corner protector device.

[0030] Specifically, the second clamping plate 5 has two parallel connecting plates 55 spaced apart, and a connecting shaft 56 is provided between the two connecting plates 55. One end of the movable rod 7 has a connecting block 73, and the connecting block 73 is also provided with a connecting hole that mates with the connecting shaft 56. The movable rod 7 is installed between the two connecting plates 55 through the connection hole and the connecting shaft 56, so that the engagement between the movable rod 7 and the second clamping plate 5 is stable and the movable rod 7 can rotate smoothly on the second clamping plate 5.

[0031] like Figure 4 As shown, the second clamping plate 5 is also provided with a buckle plate 57 parallel to the second clamping plate 5, and the buckle plate 57 is located between the second clamping plate 5 and the mounting plate 12. The buckle plate 57 provided on the second clamping plate 5 is used to facilitate the movement of the second clamping plate 5 relative to the mounting plate 12, so as to install the display screen corner protector to the corner of the display screen or remove the display screen corner protector from the display screen.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
