DETAILED DESCRIPTION

[0023] 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.

[0024] like Figures 1 to 5 As shown, the utility model provides a LED display box structure, including a display box 1, a first notch 2 and a positioning groove 8 are provided on the back of the display box 1, and further includes:

[0025] A splicing component, which is arranged on the back of the display screen cabinet 1 and is used to accurately connect two sets of display screen cabinets 1;

[0026] A positioning structure, which is arranged on the splicing component and is used to position the splicing component;

[0027] The splicing assembly includes a fixing member 3, which is installed inside the first slot 2, and a movable rod 5 is sleeved inside the fixing member 3, and a pressure plate 7 is installed at the end of the movable rod 5, and also includes a positioning plate 9, which is sleeved with the positioning groove 8, and a second spring 10 is sleeved on the outer surface of the positioning plate 9, and a fixed shaft 11 is installed inside the first slot 2, and a rotating plate 12 is sleeved on the outer surface of the fixed shaft 11, and a sliding groove 13 is opened on the top of the rotating plate 12, and a connecting plate 14 is installed on one side of the pressure plate 7, and a round shaft 4 is installed on the outside of the connecting plate 14;

[0028] Among them, the positioning structure includes a gear 15, which is installed at the end of the fixed shaft 11, and also includes a second slot 16, which is opened on one side of the rotating plate 12. A connecting rod 17 is installed inside the second slot 16, and a block 18 and a first spring 6 are sleeved on the outer surface of the connecting rod 17.

[0029] Through the cooperation between the fixed shaft 11 and the rotating plate 12, the rotating plate 12 can rotate along the outer surface of the fixed shaft 11. At the same time, through the cooperation between the slide groove 13 and the circular shaft 4, the pressure plate 7 will be driven to move through the connecting plate 14, so that the pressure plate 7 will drive the movable rod 5 to move along the inside of the fixing part 3. At this time, the pressure plate 7 will squeeze the positioning plate 9 to make it pass through the positioning groove 8. At the same time, through the cooperation between the first spring 6 and the card block 18, the card block 18 is driven to engage with the gear 15 to position the rotating plate 12, so that the positioning plate 9 can be driven to be spliced ​​with the positioning plate 9 opened by an adjacent group of display screen boxes 1, and then the two groups of display screen boxes 1 can be quickly calibrated when they are docked.

[0030] There are two groups of pressing plates 7 inside each group of first notches 2 . The pressing plates 7 are in the form of a right triangle, and the pressing plates 7 are in compression contact with the positioning plates 9 .

[0031] Through the cooperation between the pressing plate 7 and the positioning plate 9, when the pressing plate 7 presses the positioning plate 9, the end of the positioning plate 9 will be driven to pass through the positioning groove 8. By controlling one group of pressing plates 7, it is convenient to control the docking position of the display screen box 1 so that it can dock with the positioning groove 8 opened in an adjacent group of display screen boxes 1.

[0032] The second spring 10 is elastically supported between the positioning groove 8 and the positioning plate 9 , and the positioning plate 9 between two adjacent groups of display screen boxes 1 is sleeved with the positioning groove 8 .

[0033] Through the design of the second spring 10, the positioning plate 9 has good elastic reset performance. At this time, since the second spring 10 is in a compressed state, it will apply an elastic force to the positioning plate 9. Therefore, when the pressure plate 7 releases the pressure on the positioning plate 9, the second spring 10 will push the positioning plate 9 to reset.

[0034] The slide groove 13 and the round shaft 4 are slidably matched.

[0035] Through the cooperation between the slide groove 13 and the round shaft 4, when the rotating plate 12 rotates along the outer surface of the fixed shaft 11, the round shaft 4 will be driven through the slide groove 13, so that the connecting plate 14 will push the pressure plate 7 to make the movable rod 5 move along the inside of the fixing part 3, so that the positioning plate 9 can be driven to move through the pressure plate 7.

[0036] One side of the clamping block 18 is tooth-shaped, and the clamping block 18 is meshedly connected with the gear 15 .

[0037] Through the cooperation between the block 18 and the connecting rod 17, the block 18 can move along the outer surface of the connecting rod 17. At the same time, through the cooperation between the block 18 and the gear 15, the movement of the rotary plate 12 will be restricted, so that the movement of the pressure plate 7 can be restricted by the connecting plate 14.

[0038] The first spring 6 is elastically supported between the clamping block 18 and the second notch 16 .

[0039] The design of the first spring 6 allows the block 18 to have good elastic reset performance. At this time, since the first spring 6 is in a compressed state, an elastic force is applied to the block 18, so that the rotating plate 12 can be limited by the cooperation between the block 18 and the gear 15.

[0040] The working principle and use process of this utility model:

[0041] First, according to the splicing position of the display screen box 1, pull the rotating plate 12 to rotate along the outer surface of the fixed shaft 11, and at the same time, through the cooperation between the slide groove 13 and the circular shaft 4, the pressure plate 7 will be driven to move through the connecting plate 14, so that the pressure plate 7 will drive the movable rod 5 to move along the inside of the fixing part 3. At this time, the pressure plate 7 will squeeze the positioning plate 9 to make it pass through the positioning groove 8. At the same time, through the cooperation between the first spring 6 and the card block 18, the card block 18 is driven to engage with the gear 15 to position the rotating plate 12, so that the positioning plate 9 can be driven to be spliced ​​with the positioning plate 9 opened by an adjacent group of display screen boxes 1. Finally, the two groups of display screen boxes 1 can be fixed by screws, and then the two groups of display screen boxes 1 can be quickly calibrated when they are docked.
