Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and particularly relates to a display screen with a protection mechanism. Background Art

[0002] Liquid crystal display screens have been widely used in our daily lives. Due to the characteristics of being thin, light, easy to carry, and saving space, liquid crystal display screens have gradually replaced traditional display screens. However, because of their relatively thin body, they are also prone to situations such as falling.

[0003] The existing Chinese patent: A computer display screen, patent number: CN203311321U, includes a display screen body, a base, and a connecting body. An infrared sensor is provided on one side of the display screen body, and pulleys are provided under the base. The infrared sensor is connected to the internal driving device of the pulleys; the connecting body includes a core shaft and a shaft sleeve. The upper end of the core shaft is connected to the display screen body, and the lower end is inserted into the shaft sleeve connected to the base; the display screen body is also provided with a thermometer for measuring the temperature of the computer. The computer display screen of the utility model has a simple structure and reasonable design. It uses an infrared sensor to sense the human body's position and automatically adjusts the distance between the display screen and the human eye, effectively protecting the user's eyesight. At the same time, the design of the rotating shaft of the connecting body enables the display screen to swing flexibly, facilitating the user to read from any direction. According to the display of the thermometer, the computer usage time can be reasonably controlled, effectively protecting the computer and extending its service life.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: The existing display screens are relatively thin and lack protection devices. If they are collided during use, they may fall from the desktop, resulting in screen fragmentation. Summary of the Utility Model

[0005] (1) Technical problems to be solved

[0006] In view of the deficiencies of the prior art, the utility model provides a display screen with a protection mechanism, which solves the technical problems that the existing display screens are relatively thin and lack protection devices, and may fall from the desktop if collided during use, resulting in screen fragmentation.

[0007] (2) Technical solutions

[0008] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0009] A display screen with a protection mechanism, including an outer frame. Receiving grooves are provided at the four corners of the outer frame, and support rods are rotatably installed inside the four receiving grooves; through holes are provided at the side ends of the support rods, and a tension spring is fixedly installed at the side ends of the support rods. A limit sleeve is fixedly installed at the side end of the outer frame, and a limit rod is slidably installed inside the limit sleeve; the four ends of the limit rod can slide along the through holes provided at the side ends of the support rods. A support rod is fixedly installed at the bottom end of the outer frame, and a locking rod is slidably installed inside the support rod; a sliding groove is provided at the side end of the support rod for the limit rod to slide. The locking rod is fixedly connected to the limit rod. A base is rotatably installed at the bottom end of the support rod, and a spring is installed on the outer side wall of the locking rod.

[0010] Preferably: A sliding plate is slidably installed inside the base.

[0011] Preferably: A display is fixedly installed inside the outer frame.

[0012] (III) Beneficial effects

[0013] First, under the weight pressure of the outer frame, the locking rod will slide upward against the elastic force of the spring and contract into the support rod. The locking rod will push the limit rod to slide upward, so that the four ends of the limit rod slide and are respectively inserted into the through holes of the four support rods to fix the support rods. When the display screen tilts or falls, the locking rod loses restraint and will pop out outward under the action of the elastic force of the spring, which will pull the limit rod to slide. After the limit rod slides out of the through hole of the support rod, the support rod will quickly pop out outward under the action of the pulling force of the tension spring, forming four support legs at the four corners of the outer frame, so that the display will not directly contact the ground. By using the spring to push the locking rod, the support rods are unfolded during a fall, achieving the effect of protecting the display during a fall.

[0014] Second, bend the four support rods inward so that the display faces down and adheres to a flat tabletop. There is a certain distance between the display and the side of the outer frame to ensure that the display will not be damaged when on the tabletop. Then press the locking rod to insert the limit rod into the through hole at the side end of the support rod to fix the support rod. Slide the sliding plate into the base so that the sliding plate abuts against the locking rod to complete the fixation. Then place the display screen back in the correct position and pull out the sliding plate to release the limit on the locking rod. Ornaments or speakers can be placed on the pulled-out sliding plate. By using the sliding plate, the display screen is convenient to use, achieving the effect of improving practicality. Description of the drawings

[0021] In the embodiment of the present application, by providing a display screen with a protection mechanism, the technical problem that the existing display screen is relatively thin and lacks a protection device, and may fall from the desktop during use if it is collided, resulting in the screen being broken, is effectively solved. The lock rod is pressed by the weight of the outer frame and will slide upward against the elastic force of the spring and contract into the support rod. The lock rod will push the limiting rod upward, causing the four ends of the limiting rod to slide and insert into the through holes of the four support rods respectively to fix the support rods. When the display screen tilts or falls, the lock rod loses its restraint and will pop out outward under the action of the elastic force of the spring, pulling the limiting rod to slide. After the limiting rod slides out of the through hole of the support rod, the support rod will quickly pop out outward under the action of the pulling force of the tension spring, forming four support legs at the four corners of the outer frame, so that the display does not directly contact the ground. By pushing the lock rod with the spring, the support rod is unfolded during the fall, achieving the effect of protecting the display during the fall. Bend the four support rods inward so that the display is placed face down on a flat desktop, and there is a certain distance between the display and the side of the outer frame to ensure that the display will not be damaged when on the desktop. Then press the lock rod to insert the limiting rod into the through hole on the side of the support rod to fix the support rod. Slide the slide plate into the base so that the slide plate abuts against the lock rod to complete the fixation. Then place the display screen back in place correctly, pull out the slide plate to release the limit on the lock rod. Ornaments or speakers can be placed on the pulled-out slide plate. The display screen is made convenient to use through the slide plate, achieving the effect of improving the practicality.

[0022] Embodiment

[0023] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing display screen is relatively thin and lacks a protection device, and may fall from the desktop during use if it is collided, resulting in the screen being broken. The general idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a display screen with a protection mechanism, including an outer frame 1. Receiving grooves 2 are formed at the four corners of the outer frame 1, and a support rod 3 is rotatably installed inside the four receiving grooves 2; through holes are formed at the side ends of the support rod 3, a tension spring 4 is fixedly installed at the side end of the support rod 3, and a limit sleeve 5 is fixedly installed at the side end of the outer frame 1.

[0025] A limit rod 6 is slidably installed inside the limit sleeve 5; the four ends of the limit rod 6 can slide along the through holes formed at the side end of the support rod 3. A support rod 7 is fixedly installed at the bottom end of the outer frame 1, a locking rod 9 is slidably installed inside the support rod 7, and the locking rod 9 is fixedly connected to the limit rod 6.

[0026] Chute grooves are formed at the side end of the support rod 7 for the limit rod 6 to slide. A base 8 is rotatably installed at the bottom end of the support rod 7. A spring 13 is installed on the outer side wall of the locking rod 9. A sliding plate 11 is slidably installed inside the base 8, and a display 12 is fixedly installed inside the outer frame 1.

[0027] Working principle:

[0028] First step, place the display screen on the table. The locking rod 9 is pressed by the weight of the outer frame 1, and it will slide upward against the elastic force of the spring 13 and retract into the support rod 7. The locking rod 9 will push the limit rod 6 to slide upward, so that the four ends of the limit rod 6 slide and are respectively inserted into the through holes of the four support rods 3 to fix the support rods 3. When the display screen tilts or falls, the locking rod 9 loses restraint and will pop out outward under the action of the elastic force of the spring 13, and then it will pull the limit rod 6 to slide. After the limit rod 6 slides out of the through hole of the support rod 3, the support rod 3 will quickly pop out outward under the action of the pulling force of the tension spring 4, forming four support legs at the four corners of the outer frame 1, so that the display 12 will not directly contact the ground. By pushing the locking rod 9 with the spring 13, the support rod 3 is unfolded when falling, achieving the effect of protecting the display 12 when falling.

[0029] Second step, after use, bend the four support rods 3 inward so that the display 12 faces down and adheres to a flat tabletop. There is a certain distance between the display 12 and the side of the outer frame 1 to ensure that the display 12 will not be damaged when on the tabletop. Then press the locking rod 9 to insert the limit rod 6 into the through hole at the side end of the support rod 3 to fix the support rod 3. Then slide the sliding plate 11 into the base 8 so that the sliding plate 11 abuts against the locking rod 9 to complete the fixation. Then place the display screen back in place correctly, pull out the sliding plate 11 to release the limit on the locking rod 9. Ornaments or speakers can be placed on the pulled-out sliding plate 11. The sliding plate 11 makes the display screen easy to use, achieving the effect of improving the practicality.

[0030] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
