Description

Technical Field

[0001] The utility model relates to the field of display devices, and specifically to a display device based on blockchain. Background Art

[0002] With the continuous advancement of science and technology and the development of information technology, blockchain has entered the public eye. Blockchain is regarded as an important breakthrough for independent innovation of core technologies, accelerating the innovative development of blockchain technology and industry. Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it has the characteristics of being unforgeable, traceable throughout the process, traceable, open and transparent, and collectively maintained.

[0003] According to application number 202022154328.2, a public welfare information data display device based on blockchain is disclosed, including a switch support frame bottom plate and a display screen, and an adjustment structure is installed inside the support frame. The utility model is provided with an adjustment structure inside the support frame, and the support height of the display screen can be adjusted as needed during use. When in use, the clamping block can be pressed to retract it into the groove through the action of the spring, so that the movable rod and the support frame lose the fixing force, and the movable rod is adjusted to rise and shrink inside the support frame. After the position is determined, the clamping block is released, so that it is clamped with the notch set on the outer wall of the support frame through the action of the spring, and the position height of the support frame is determined. When the movable rod is active, the limit block installed on the outer wall of the movable rod can perform a limit-guiding activity inside the limit groove set on the outer wall of the support frame, so that the lifting and lowering are smoother.

[0004] The above scheme makes it more convenient to adjust the support height of the display screen through this setting, and has better applicability, but the above scheme still has certain shortcomings in actual use; although the adjustment of the height of the display screen is achieved, the display device in the above scheme cannot be disassembled, and the device occupies a large space when it is subsequently returned to its original position, so the space for stacking is limited, which greatly reduces the practicality of the existing display device. For this reason, we provide a display device based on blockchain. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4As shown, the utility model provides a technical solution: a display device based on blockchain, including a base plate 1, the bottom surface of the base plate 1 is threadedly connected to two screws 2, and the bottom end of the screw 2 is fixedly connected to a support frame 3, and the threaded connection between the base plate 1 and the screw 2 can be used to adjust the height of the base plate 1, thereby facilitating the subsequent use of the display device. At the same time, the support frame 3 can ensure the stability of the device when in use, and can ensure the normal use of the subsequent device.

[0023] Two vertical boards 4 are fixedly connected to the upper surface of the bottom plate 1, and two display boards 5 are installed between the two vertical boards 4. The vertical boards 4 can fix the display boards 5, so as to facilitate the normal use of the subsequent display boards 5 and ensure the display effect of the display boards 5.

[0024] A snap-on assembly 6 is installed inside the vertical plate 4, and the snap-on assembly 6 includes two square grooves 601 and two snap-on holes 602. The two square grooves 601 are respectively opened on the upper surfaces of the two vertical plates 4, and the two snap-on holes 602 are respectively opened on the outer surfaces of the two vertical plates 4. The outer surface of each square groove 601 is slidably connected with a sliding rod 603, and the ends of the two sliding rods 603 close to each other are fixedly connected with a circular plate 604, and the outer surfaces of the two circular plates 604 are fixedly connected with tension springs 605, and the tension springs 605 are sleeved on the outer surfaces of the sliding rods 603, and the ends of the two tension springs 605 away from each other are in contact with the side surfaces of the square grooves 601 close to each other, and the ends of the two sliding rods 603 close to each other are respectively snap-oned with the inner walls of the two snap-on holes 602.

[0025] By the engagement between the slide bar 603 and the engagement hole 602, and by utilizing the elastic force of the tension spring 605 and the limiting position of the slide bar 603 by the circular plate 604, the slide bar 603 can have a certain reset ability, so that the slide bar 603 can limit and fix the display board 5, thereby ensuring the stability of the display board 5 during use and ensuring the subsequent normal use of the display board 5.

[0026] The outer surfaces of the two slide bars 603 are fixedly connected with pull rings 606. The set pull rings 606 provide a certain convenience for pulling the slide bars 603, which can ensure that subsequent disassembly or installation is more convenient.

[0027] The snap-on assembly 6 also includes two fixing rods 609, both of which are fixedly connected to the bottom surface of the display board 5, the inner walls of the two square grooves 601 are fixedly connected with fixing plates 607, and the upper surface of the fixing plate 607 is provided with a fixing hole 608, and the outer surface of the fixing rod 609 is snap-on with the inner wall of the fixing hole 608.

[0028] By using the clamping connection between the fixing rod 609 and the fixing hole 608 , the bottom surface of the display board 5 can be fixed, and the display board 5 can be prevented from being offset when it is used again, thereby ensuring the normal use effect of the display board 5.

[0029] A limit assembly 7 is installed between the two vertical plates 4. The limit assembly 7 includes a cylinder 701. The cylinder 701 is installed on the upper surface of the display board 5. A sliding groove 702 is provided on the inner wall of the cylinder 701. A moving cylinder 703 is slidably connected to the inner wall of the sliding groove 702. The sliding connection between the sliding groove 702 and the moving cylinder 703 can guide the movement of the moving cylinder 703 to a certain extent, so that subsequent card connection will not go wrong, thereby ensuring the normal use of the subsequent display device.

[0030] A connecting block 704 is installed inside the movable cylinder 703, and a spring 705 is fixedly connected to the upper surface of the connecting block 704. A group of connecting holes 707 are opened on the outer surface of the cylinder 701, and a convex circular plate 706 is slidably connected to the inner wall of the connecting hole 707. The bottom end of the convex circular plate 706 is slidably connected to the outer surface of the movable cylinder 703, and the bottom end of the convex circular plate 706 is fixedly connected to the top of the spring 705. The spring 705 is set to allow the convex circular plate 706 to have a certain rebound ability, so that when the convex circular plate 706 slides into the interior of the connecting hole 707, the two cylinders 701 can be prevented from separating, thereby ensuring the subsequent normal use of the two display boards 5.

[0031] The outer surface of the movable cylinder 703 is fixedly connected with a pull rod 708. The pull rod 708 is not only convenient for subsequent staff to take out the cylinder 701, but also can make a certain contact with the cylinder 701. After the contact, the cylinder 701 can be limited, so that the two cylinders 701 will not be separated, thereby ensuring the normal use of the subsequent display board 5. The outer surface of the pull rod 708 is covered with a rubber sleeve, which can prevent the staff from slipping when pulling, and can ensure that the pull rod 708 can be pulled out or put in normally.

[0032] When the display device is used, first hold the pull rod 708, then press the convex circular plate 706 downward into the inner wall of the cylinder 701, and then pull the movable cylinder 703 out of the inside of the cylinder 701, so as to limit the upper half between the two display boards 5, and then pull the two sliding rods 603 away from each other through the pull ring 606. During the pulling process, the tension spring 605 will be squeezed, so that the sliding rod 603 will come out from the inner wall of the clamping hole 602, so as to achieve the limit fixation in the middle between the two display boards 5, and then pull the fixing rod 609 out of the fixing hole 608 to complete the disassembly of the display board 5, and finally remove the two screws 2 from the bottom surface of the bottom plate 1, so as to complete the disassembly of the entire display device, which is convenient for people to store the display device later.
