Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and more specifically, to a portable display screen. Background Technology

[0002] A display screen is a computer output device. It is a display tool that displays certain electronic documents on the screen through specific transmission equipment. It can be divided into cathode ray tube displays, plasma displays (PDP), and liquid crystal displays (LCD).

[0003] With the popularization of digital office, mobile teaching, outdoor live streaming and other scenarios, users have put forward higher requirements for the portability of display devices. The structural design of traditional displays has long been centered on static desktop use scenarios, and its core components are in fundamental conflict with the need for mobile portability. Although the concept of "portable display" has been proposed in the consumer electronics field, most existing products have only achieved limited improvements through partial size reduction, and have failed to break through the structural portability bottleneck. Traditional displays mostly adopt a rigid combination structure of display body and bottom bracket. This design results in a completely fixed screen shape, which cannot be reduced in storage volume by folding or other means, and is also difficult to withstand high-frequency vibration or accidental pressure in mobile scenarios, which brings inconvenience to people's daily carrying. Therefore, it is necessary to improve it. Utility Model Content

[0031] 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.

[0032] like Figures 1 to 9 As shown, this utility model provides a portable display screen, comprising:

[0033] A base 1, a first hinge block 2 is fixedly installed at the front of the top of the base 1, a rotating block 3 is hinged on the first hinge block 2, and a display screen 4 is fixedly installed on the outer surface of the rotating block 3.

[0034] Folding mechanism, the folding mechanism is located inside the top of the base 1;

[0035] The folding mechanism includes a moving block 6, the outer surface of which is slidably connected to the inside of the top of the base 1. A moving rod 12 is movably sleeved on the outer surface of the moving block 6, and an arc-shaped block 13 is movably sleeved on the other end of the moving rod 12. The outer surface of the arc-shaped block 13 is fixedly connected to the display screen 4. Square rods 7 are fixedly installed on both the left and right ends of the moving block 6. A toothed plate 29 is fixedly installed on the other end of the square rod 7. A gear 8 is meshed on the outer surface of the toothed plate 29. The gear 8 is movably sleeved with the inside of the base 1. A rack 9 is meshed on the outer surface of the gear 8. A connecting block 10 is fixedly installed at the front end of the rack 9. A handle 11 is fixedly installed on the front of the connecting block 10.

[0036] Since the rotating block 3 is hinged to the first hinge block 2, the display screen 4 can drive the rotating block 3 to rotate around the first hinge block 2 as the axis. At this time, the display screen 4 will fold and store itself during rotation. When the moving block 6 moves backward along the inside of the top of the base 1, it will simultaneously drive the square rod 7 and the moving rod 12 to move backward. At this time, the moving rod 12 will pull the display screen 4 through the arc block 13, causing the display screen 4 to rotate. At the same time, the square rod 7 will drive the toothed plate 29 to move backward. Since the toothed plate 29 is meshed with the gear 8 and the gear 8 is meshed with the rack 9, the gear 8 will rotate under the drive of the toothed plate 29. Then, the gear 8 will drive the connecting block 10 to move forward along the inside of the base 1 through the rack 9. At this time, the handle 11 will move forward under the drive of the connecting block 10. When the handle 11 moves to the outside of the base 1, the operator will be able to move the display screen 4 as a whole by holding the handle 11.

[0037] The base 1 has a groove 14 inside, and a slider 15 is slidably connected inside the groove 14. The outer surface of the slider 15 is fixedly connected to the connecting block 10.

[0038] When the connecting block 10 moves back and forth, it will drive the slider 15 to move back and forth along the inside of the groove 14. Due to the design of the groove 14 and the slider 15, the connecting block 10 will be more stable when it moves back and forth.

[0039] The moving block 6 has a screw 5 threaded inside, and the outer surfaces of both ends of the screw 5 are movably connected to the inside of the base 1. The rear end of the screw 5 is fixedly installed with a screwing block 16.

[0040] When the operator turns the turning block 16, the screw 5 will rotate under the drive of the turning block 16. Since the screw 5 is threadedly connected to the moving block 6, the moving block 6 will move backward along the inside of the top of the base 1 under the drive of the screw 5.

[0041] The base 1 has a foot pad 28 fixedly installed at its bottom end. The foot pad 28 is made of rubber.

[0042] The design of the foot pad 28 will increase the anti-slip properties of the bottom of the base 1.

[0043] The base 1 has a second hinge block 17 fixedly installed on both the left and right sides at the rear of the top, and a rotating plate 18 is hinged to the second hinge block 17.

[0044] Since the second hinge block 17 is hinged to the rotating plate 18, the rotating plate 18 can rotate around the second hinge block 17 as the axis.

[0045] The base 1 has a slide rail 19 fixedly installed on the right side of its top, and a movable block 20 is slidably connected inside the slide rail 19.

[0046] Because the slide rail 19 limits the movement of the movable block 20, the movable block 20 can only move back and forth along the inside of the slide rail 19.

[0047] The movable block 20 is internally hinged to a movable rod 21, and the other end of the movable rod 21 is internally hinged to a third hinge block 22. The outer surface of the third hinge block 22 is fixedly connected to the rotating plate 18.

[0048] When the third hinge block 22 rotates under the drive of the rotating plate 18, it will press the movable rod 21. At this time, the movable rod 21 will push the movable block 20, causing the movable block 20 to move forward along the inside of the slide rail 19.

[0049] The movable block 20 has a first spring 23 fixedly installed on its front side, and the front end of the first spring 23 is fixedly connected to the inside of the slide rail 19.

[0050] When the movable block 20 moves forward along the inside of the slide rail 19, it will compress the first spring 23. Due to the design of the first spring 23, it will play a good restoring role in the movement of the movable block 20.

[0051] A fixing block 24 is fixedly installed on the right side of the slide rail 19, a pull block 26 is movably sleeved inside the fixing block 24, and a plug rod 25 is fixedly installed on the left side of the pull block 26.

[0052] When the insertion rod 25 is pressed and pushed, it will drive the pull block 26 to move to the right along the inside of the fixed block 24. When the operator moves the pull block 26, the pull block 26 will drive the insertion rod 25 to move to the right.

[0053] The left side of the pull block 26 is fixedly installed with a plug rod 25, and the right end of the plug rod 25 is fixedly connected to the inside of the fixing block 24.

[0054] When the pull block 26 moves to the right along the inside of the fixed block 24, the second spring 27 will be compressed by the pull block 26. Due to the design of the second spring 27, it will play a good restoring role for the overall movement of the pull block 26.

[0055] Working principle and usage process of this utility model:

[0056] When the operator needs to store the display screen 4, the operator first turns the turning block 16. At this time, the screw 5 will rotate under the drive of the turning block 16. Since the outer surface of the screw 5 is threaded with the inner thread of the moving block 6, when the screw 5 rotates, it will drive the moving block 6 to move backward along the inside of the base 1. At this time, the moving block 6 will simultaneously drive the two square rods 7 and the two moving rods 12 to move. At this time, the two moving rods 12 will pull the two arc blocks 13 respectively, so that the two arc blocks 13 drive the display screen 4 as a whole to move. At this time, the display screen 4 will drive the rotating block 3 to rotate around the hinge point with the first hinge block 2 as the axis. At this time, the display screen 4 will fold and store during rotation. When the display screen 4 rotates 90 degrees, the folding and storage is completed. At the same time, the two square rods 7 will move backward along the inside of the base 1. At this time, the two toothed plates 29 will move backward under the drive of the two square rods 7. Since the outer surface of the two toothed plates 29 is threaded with the outer surface of the two gears 8 respectively, the two toothed plates 29 will fold and store backward. The surfaces are meshed together, so when the two square rods 7 move backward, they will drive the two gears 8 to rotate in the opposite direction. Since the outer surfaces of the two gears 8 are meshed with the outer surfaces of the two racks 9, when the two gears 8 rotate in the opposite direction, they will drive the two racks 9 to move. At this time, the connecting block 10 will move under the drive of the racks 9. The connecting block 10 will drive the two sliders 15 to move along the inside of the two slide grooves 14. Due to the design of the inside of the two slide grooves 14, the movement of the two sliders 15 will be limited, so that the sliders 15 can only move back and forth. At this time, the connecting block 10 will drive the two sliders 15 to move forward. At the same time, the handle 11 will move forward under the drive of the connecting block 10. Then, the handle 11 will move to the outside of the base 1 during the forward movement. Due to the design of the handle 11, the operator can move the base 1 as a whole by holding the handle 11, thus realizing the function of conveniently carrying the display screen 4.

[0057] After the display screen 4 is folded and stowed, the operator pushes the rotating plate 18, causing it to rotate around the hinge point with the second hinge block 17. During this process, the rotating plate 18 drives the third hinge block 22 to rotate. The movable rod 21 then moves under the influence of the third hinge block 22. The other end of the movable rod 21 then presses and pushes the movable block 20, causing it to move. Due to the internal design of the slide rail 19, the movement of the movable block 20 is limited, allowing it to move only forward and backward. The movable block 20 then moves forward along the inside of the slide rail 19 under the influence of the movable rod 21. During this process, the movable block 20 compresses the first spring 23. The design of the first spring 23 provides a good restoring effect for the overall movement of the movable block 20. When the movable block 20 contacts the insertion rod 25 during its forward movement, it presses and pushes the insertion rod 25. The insertion rod 25 causes the pull block 26 to move to the right along the inside of the fixed block 24. At this time, the second spring 27 will be compressed. When the rotating plate 18 rotates 90 degrees, the outer surface of the rotating plate 18 will be in contact with the top of the base 1. At this time, the rotating plate 18 will provide good protection for the display screen 4, thus realizing the function of protecting the display screen 4. At this time, the square slot on the movable block 20 will be aligned with the insertion rod 25. Due to the elastic force of the second spring 27, the second spring 27 will drive the insertion rod 25 to reset to the left through the pull block 26. At this time, the insertion rod 25 will be inserted into the inside of the upper slot of the movable block 20 during the leftward movement, thereby blocking the backward movement of the movable block 20 and locking the rotating plate 18. When the operator moves the pull block 26 to move to the right, the insertion rod 25 will release the lock on the movable block 20. At this time, the entire movable block 20 will move to the left and reset under the action of the first spring 23.
