Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a liquid crystal display screen with a convenient protective film replacement. Background Technology

[0002] A display screen is an electronic output device whose main function is to convert the electrical signals generated by electronic devices (such as computers, mobile phones, televisions, game consoles, dashboards, etc.) into visual image information and present it to the user.

[0003] After a period of use, screen protectors usually need to be replaced due to dust accumulation or scratches. The current method of replacing screen protectors involves peeling off the old one and manually applying the new one to the screen. This manual application method is relatively primitive, cannot accurately align with the screen, requires a high level of skill, and is prone to misalignment.

[0004] Therefore, it is necessary to design a liquid crystal display screen that allows for easy replacement of the protective film in order to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the drawback that applying a protective film requires a high level of manual skill, the technical problem to be solved is to provide a liquid crystal display screen that allows for easy replacement of the protective film.

[0006] The technical solution is as follows: A liquid crystal display screen with a convenient protective film replacement, characterized in that it includes a base, a display screen, a sliding frame, bolts, a guide rod, limiting blocks, a handle, a support frame, a first clamping plate, a second clamping plate, torsion springs, and a proximity mechanism. The display screen is fixedly connected to the top of the base. The sliding frame is slidably connected to the rear side of the display screen. The bolt is rotatably connected to the left side of the display screen. The left side of the sliding frame is threadedly engaged with the bolt. The guide rod is slidably connected to the upper part of the sliding frame. A threaded groove is opened on the left side of the guide rod. Two limiting blocks are fixedly connected to both sides of the guide rod. The handle is rotatably connected to the upper part of the sliding frame. The handle is threadedly engaged with the threaded groove. Two support frames are rotatably connected to both sides of the guide rod, and each support frame is located between corresponding limiting blocks. The lower part of the two support frames on the same side is rotatably connected to the first clamping plate. The front part of the two first clamping plates is rotatably connected to the second clamping plate. Two torsion springs are sleeved between the front parts of the corresponding first clamping plates and second clamping plates. A proximity mechanism is provided between the two first clamping plates.

[0007] Furthermore, the proximity mechanism includes a connecting rod, a knob, and a rubber pad. A connecting rod is fixedly connected between the two first clamping plates, and a knob is fixedly connected to the side of the two connecting rods that are far apart from each other. Rubber pads are fixedly connected to both sides of the lower part of each support frame.

[0008] Furthermore, it also includes a film-removing plate, a positive magnet, and a negative magnet. The film-removing plate is placed on the right side of the display screen, behind the original protective film, which covers it. Embedded positive magnets are symmetrically fixedly connected to the right side of the display screen, and negative magnets are symmetrically fixedly connected to the center of the film-removing plate. The positions of the two positive magnets and the two negative magnets correspond to each other.

[0009] Furthermore, it also includes anti-slip pads, with anti-slip pads fixedly connected to the sides of the first and second clamps that are close to each other on the same side.

[0010] Furthermore, each support frame has a slot at the rear that corresponds to the sliding frame.

[0011] Furthermore, the film-tearable panel is made of high-resilience plastic.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model achieves automatic clamping and fine adjustment through the first clamping plate, the second clamping plate, the torsion spring and the sliding frame, which replaces the manual lifting of the protective film for alignment, thereby reducing manpower consumption and human error.

[0013] 2. This utility model increases the friction of film clamping by using the anti-slip pad built into the clamping plate, thereby increasing stability during the film application process.

[0014] 3. This utility model uses a magnetic assisted film-peeling function to achieve one-click peeling of the old film, avoiding direct contact with the screen and causing scratches.

[0015] 4. This utility model allows the slot to engage with the sliding frame by rotating counterclockwise, thus keeping the support frame fixed when not in operation. Attached Figure Description

Detailed Implementation

[0024] Example: A liquid crystal display screen with a convenient protective film replacement, such as... Figures 1-7 As shown, the device includes a base 1, a display screen 2, a sliding frame 3, bolts 301, a guide rod 4, a limiting block 401, a handle 5, a support frame 6, a first clamping plate 7, a second clamping plate 8, a torsion spring 9, and a proximity mechanism. The display screen 2 is bolted to the top of the base 1. The sliding frame 3 is slidably connected to the upper rear side of the display screen 2. Bolts 301 are rotatably connected to the upper left side of the display screen 2. The left side of the sliding frame 3 is threadedly engaged with bolts 301. A guide rod 4 is slidably connected to the upper part of the sliding frame 3. A threaded groove is provided on the left side of the guide rod 4. Two limiting blocks 4 are glued to both sides of the guide rod 4. 01. A handle 5 is rotatably connected to the upper left side of the sliding frame 3. The handle 5 is threaded into the threaded groove. Two support frames 6 are rotatably connected to the left and right sides of the guide rod 4. Each support frame 6 has a corresponding slot at the rear of the sliding frame 3. Each support frame 6 is located between corresponding limit blocks 401. The lower part of the two support frames 6 on the same side is rotatably connected to a first clamping plate 7. The front part of the two first clamping plates 7 is rotatably connected to a second clamping plate 8. Two torsion springs 9 are sleeved between the front parts of the corresponding first clamping plates 7 and second clamping plates 8. A contacting mechanism is provided between the two first clamping plates 7.

[0025] like Figure 5 and Figure 6 As shown, the proximity mechanism includes a connecting rod 10, a knob 11, and a rubber pad 12. The connecting rod 10 is glued between the two first clamping plates 7. The knob 11 is glued to the side of the two connecting rods 10 that are far apart from each other. The rubber pad 12 is glued to the left and right sides of the lower part of each support frame 6.

[0026] When operators need to use this device to assist in replacing the protective film, first, place the device on a stable table. Then, peel off the old protective film and clean the display screen 2. Rotate the support frame 6 clockwise. When the support frame 6 rotates to a certain angle, it will be limited by the limiting block 401. Then, pry open the first clamping plate 7 and the second clamping plate 8. At this time, the torsion spring 9 will be stretched. After placing the new protective film between the first clamping plate 7 and the second clamping plate 8, release the first clamping plate 7 and the second clamping plate 8. At this time, the torsion spring 9 releases its restoring force, causing the first clamping plate 7 and the second clamping plate 8 to return to their original position and clamp the new protective film. Then, turn the knob 11 clockwise to rotate the first clamping plate 7 and the second clamping plate 8 clockwise together. At this time, the new protective film will be close to the display screen 2. Then, through the front and back... The rotating bolt 301 drives the sliding frame 3, guide rod 4, support frame 6, first clamping plate 7, second clamping plate 8, and new protective film to make up-down fine adjustments. The forward and reverse handle 5 drives the guide rod 4, support frame 6, first clamping plate 7, second clamping plate 8, and new protective film to make left and right fine adjustments. When the fine adjustment is in the appropriate position, the new protective film can be firmly attached to the surface of the display screen 2 from bottom to top. Then, the first clamping plate 7 and second clamping plate 8 are pried apart again, and the torsion spring 9 is stretched again. After the knob 11 is reversed to reset, the first clamping plate 7 and second clamping plate 8 are released. At this time, the torsion spring 9 releases the restoring force and drives the first clamping plate 7 and second clamping plate 8 to reset, ready for the next clamping. Then, the new protective film is completely attached to the display screen 2. Then, the first clamping plate 7 and second clamping plate 8 are rotated counterclockwise to the back of the display screen 2 to complete the film application.

[0027] When the film is applied and the support frame 6 is reset, the slot will lock into the sliding frame 3 when the support frame 6 is rotated counterclockwise to its limit distance. In the non-working state, the support frame 6 can remain fixed.

[0028] like Figure 7 As shown, it also includes a film-removing plate 13, a positive magnet 14, and a negative magnet 141. The film-removing plate 13 is placed on the right side of the display screen 2. The film-removing plate 13 is made of high-resilience plastic. The film-removing plate 13 is located behind the original protective film, and the original protective film covers it. Embedded positive magnets 14 are symmetrically glued to the upper and lower sides of the right side of the display screen 2. Negative magnets 141 are symmetrically glued to the upper and lower sides of the middle of the film-removing plate 13. The positions of the two positive magnets 14 and the two negative magnets 141 correspond to each other.

[0029] When it is necessary to assisted in peeling off the original protective film, the peeling plate 13 can be broken off. At this time, the positive magnet 14 and the negative magnet 141 will detach from the attraction, and the original protective film will be peeled off along with the peeling plate 13. After the entire original protective film is peeled off, the peeling plate 13 can be reset so that the positive magnet 14 and the negative magnet 141 can be re-attracted, thus completing the assisted peeling.

[0030] like Figure 4As shown, it also includes an anti-slip pad 15. The first clamping plate 7 and the second clamping plate 8 on the same side are both fixedly connected with the anti-slip pad 15 on the side that are close to each other.

[0031] When the first clamping plate 7 and the second clamping plate 8 clamp the new protective film, the anti-slip pad 15 can increase the friction between the first clamping plate 7 and the second clamping plate 8 and the new protective film, making the film application process more stable.
