Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and in particular to an adjustable display screen protective cover. Background Technology

[0002] Display screens on instruments and industrial equipment are human-machine interfaces used to display key information such as equipment operating status, parameter data, and alarm information. They are widely used in industrial automation, process control, and machinery manufacturing, helping operators monitor equipment operation in real time. Common display types include LED digital tubes, LCD screens, OLED screens, and touch screens. High-performance industrial displays typically feature high brightness and wide viewing angles. Some intelligent displays also support graphical interfaces, multilingual switching, and remote communication functions, improving ease of operation and system integration, making them an important component of modern industrial intelligence.

[0003] In complex environments such as industrial sites, the displays of instruments or various equipment often face strong light or interference from surrounding reflected light, causing glare on the screen. This obstructs the operator's view when viewing the displayed content, resulting in problems such as blurriness and reduced contrast. This can easily lead to misreading or delayed judgment, affecting work efficiency and safety. Dust easily accumulates on the surface of the display screen, which not only affects the appearance after prolonged use but also further reduces the display clarity. It may even cause hidden dangers such as poor heat dissipation or touch malfunction, seriously affecting the stable operation of the equipment and the human-computer interaction experience. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable display screen protective cover.

[0005] An adjustable display screen protective cover includes a base, a fixing plate, a fixing seat, a hinge cylinder, a top cover, a stop pin, and a retaining strip. The base is open on both the top and bottom sides. The fixing plate is connected to the base, and two fixing seats are connected to the fixing plate. The fixing seats are open on both the left and right sides. A stop pin is slidably connected inside each fixing seat. At least eight grooves are opened circumferentially inside each fixing seat. Two retaining strips are circumferentially connected to the outer wall of each stop pin. The retaining strips are slidably connected to the grooves. A hinge cylinder is rotatably connected between the two stop pins, and a top cover is connected to the hinge cylinder.

[0006] As an improvement to the above solution, it also includes a locking boss, with locking bosses connected to the outer wall of the shift pin, and locking holes adapted to the locking bosses on the hinge cylinder.

[0007] As an improvement to the above solution, grooves are provided on both the left and right sides of the gear shift pin, and the openings on the sides of the grooves that are far apart from each other are larger than the openings on the sides that are close to each other.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] An adjustable display screen cover, such as Figures 1-5 As shown, the device includes a base 1, a fixing plate 2, a fixing seat 3, a hinge cylinder 4, a top cover 5, a stop pin 6, a retaining strip 603, an anti-detachment boss 604, a limiting block 602, an L-shaped buckle 102, and a retaining block 101. The base 1 has open top and bottom sides. A fixing plate 2 is connected to the base 1. Two fixing seats 3 are fixedly connected to the top of the fixing plate 2. The fixing seats 3 have open left and right sides. A stop pin 6 is slidably connected inside each fixing seat 3. Grooves 601 are formed on both sides of the stop pin 6. The openings on the sides of the grooves 601 that are far apart are larger than the openings on the sides that are close together. Both the base 1 and the stop pin 6 are elastic. At least eight grooves 301 are formed circumferentially inside each fixing seat 3. Two retaining strips 603 are fixedly connected circumferentially at even intervals on the outer wall of each stop pin 6. The retaining strips 603 are slidably connected to the grooves 301. The two stop pins... A hinge cylinder 4 is rotatably connected between the pins 6. A top cover 5 is fixedly connected to the hinge cylinder 4. Anti-detachment protrusions 604 are fixedly connected to the outer walls of the stop pins 6. Anti-detachment holes 401 that are adapted to the anti-detachment protrusions 604 are opened on the hinge cylinder 4. Limiting blocks 602 are fixedly connected to the sides of the stop pins 6 that are far apart from each other. The outer diameter of the limiting blocks 602 is larger than the inner diameter of the fixed base 3. The front side of the base 1 is cut off. L-shaped fasteners 102 are fixedly connected to both ends of the cut-off base 1. The L-shaped fasteners 102 are centrally symmetrically arranged. The two L-shaped fasteners 102 are interlocked with each other. The inner angle of the two L-shaped fasteners 102 is 60 degrees. The 60-degree slope makes the two L-shaped fasteners 102 interlock more firmly. Two locking blocks 101 are fixedly connected to the top of the front side of the base 1. The inner wall of the front side of the top cover 5 has a locking groove 501 that is adapted to the locking blocks 101.

[0020] Initially, the two L-shaped fasteners 102 are interlocked, and the stop pins 6 are disengaged from the fixed base 3 and the hinge cylinder 4. When installing this protective cover, the two L-shaped fasteners 102 are pried open to misalign, thus releasing the interlocking state. The base 1 deforms, and the two L-shaped fasteners 102 are then moved further apart, allowing the base 1 to be pried open from the front. The base 1 is then placed on the outer wall of the display screen, and the two L-shaped fasteners 102 are released. The base 1 returns to its original shape, resetting the interlocking state. At this point, the display screen is inside the base 1. The upper cover 5 is then secured to the fastener 101 of the base 1 via the slot 501. The hinge cylinder... Position 4 between the two fixed seats 3, then grasp and press the stop pin 6 to compress and shrink the groove 601, reducing the outer diameter of the stop pin 6. Slide the stop pin 6 into the fixed seat 3 and the hinge cylinder 4, so that the limiting blocks 602 are in contact with the opposite sides of the fixed seats 3. Release the stop pin 6, and the force generated by the rebound of the stop pin 6 will make it fit tightly against the inner wall of the fixed seat 3 and the inner wall of the hinge cylinder 4. Rotate the stop pin 6 to make the retaining strip 603 engage with the groove 301 and the anti-detachment protrusion 604 engage with the anti-detachment hole 401. This completes the installation of the protective cover. At this time, both the base 1 and the top cover 5 cover the display screen, thus preventing dust accumulation on the display. When the protective cover needs to be removed, reverse the direction. The above steps can be followed. The limiting block 602 ensures that the anti-disengagement protrusion 604 and the anti-disengagement hole 401 are on the same vertical plane. It also prevents the stop pin 6 from being inserted too deeply into the hinge cylinder 4 and becoming impossible to remove. When you need to check the display, rotate the upper cover 5 upward along the circumference of the fixed base 3, so that the upper cover 5 is away from the base 1, thereby opening the protective cover. During this process, the hinge cylinder 4 drives the stop pin 6 to rotate, and the locking strip 603 disengages from the groove 301, causing the stop pin 6 to be squeezed. The locking strip 603 rotates along the inside of the fixed base 3. When the locking strip 603 approaches the adjacent groove 301, the locking strip 603 engages with the adjacent groove 301, and the stop pin 6 returns to its original state, which can make the stop pin 6 return to its original state. The strip 603 is engaged in different grooves 301, thereby controlling the opening angle of the top cover 5. When the protective cover needs to be closed, the top cover 5 is reversed so that the locking block 101 engages with the locking groove 501. This allows the opening angle of the top cover 5 to be adjusted according to the actual light direction, effectively blocking external light interference, reducing screen reflection, improving the visibility of the content displayed on the monitor, and avoiding misreading information. Under the engagement of the strip 603 and the groove 301, the top cover 5 can be prevented from rotating randomly due to vibration or accidental contact, making it convenient to read the data on the display screen and operate the display screen. The anti-detachment protrusion 604 is kept engaged in the anti-detachment hole 401, which can prevent the stop pin 6 from slipping in the hinge cylinder 4.

[0021] 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 the scope of protection of this utility model. 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 essence and scope of the technical solutions of this utility model.
