Description

Technical Field

[0001] This utility model applies to the field of LED display technology, and in particular relates to a fixing device for splicing LED displays. Background Technology

[0002] Currently, an LED display screen is a flat panel display composed of small LED module panels, used to display various information such as text, images, and videos. When installing and using the display screen, corresponding auxiliary fixing mechanisms are used to support and install it to ensure the stability of the image display.

[0003] However, current methods of installing and securing LED displays using fixing mechanisms suffer from limited applicability due to the single function of the overall structure of the fixing frame. For displays of different sizes, the fixing dimensions cannot be adjusted to improve the protection of the display. Consequently, if the fixing dimensions are unsuitable, the display may not be able to be properly embedded in the fixing frame, affecting the stability of the display. Therefore, we propose a splicing LED display fixing device. Utility Model Content

[0004] The main purpose of this utility model is to provide a fixing device for splicing LED displays, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A splicing LED display screen fixing device includes a fixing baffle, wherein a first vertical plate and a second vertical plate are detachably installed at both ends of the side of the fixing baffle;

[0007] Hollow tubes are fixedly installed at both ends of the outer side of the fixed baffle and at both ends of the side of the second vertical plate, and a pushing mechanism is provided inside the hollow tubes;

[0008] The fixed baffle has mounting grooves on both sides of the first vertical plate and the second vertical plate, and each mounting groove is equipped with an abutting mechanism, which is connected to the pushing mechanism in a transmission manner.

[0009] As an optional solution to the technical solution of this application, the pushing mechanism includes a pushing spring, a movable plate is slidably installed inside each hollow tube, and a movable rod is vertically fixedly installed at the middle of the side of each movable plate, with the pushing spring movably sleeved on the outside of the movable rod.

[0010] By adopting the above technical solution, the moving plate can be provided with a corresponding vertical restoring force through the action of the spring structure, thereby providing the pushing force required for the position restoration of the limit stop.

[0011] As an optional solution to the technical solution of this application, the abutment mechanism includes a limiting block, a fixing rod is vertically fixedly installed at the middle of the side of the movable plate, a limiting block is fixedly installed at the bottom of the fixing rod, the limiting block is movably installed inside the mounting groove, and connecting rods are horizontally fixed at both ends of the side of the first vertical plate near the fixing baffle and both ends of the side of the fixing baffle near the second vertical plate, and a pushing block is fixedly installed at the top of the side of each connecting rod.

[0012] By adopting the above technical solution, the connection between the push rod and the first vertical plate is achieved through the connecting rod, and the interaction between the push block and the limiting block allows the operator to simply push the fixed baffle, the first vertical plate, and the second vertical plate together to ensure that the first vertical plate, the second vertical plate, and the fixed baffle can be quickly spliced ​​together. This allows for a larger range of changes in the fixed area of ​​the overall mechanism, ensuring that it can be used for fixed installation of displays of different lengths and models.

[0013] As an optional solution to the technical solution of this application, the middle of the side of the first vertical plate and the second vertical plate are both screwed with adjusting bolts through threads. The top of the side of the adjusting bolt is rotatably mounted with a retaining plate through a bearing. Each retaining plate is fixedly mounted with a guide rod at both ends of its side, and the guide rod is slidably inserted into the inside of the side of the first vertical plate and the second vertical plate.

[0014] By adopting the above technical solution, the horizontal position of the clamping plate can be adjusted by adjusting the bolts, allowing the side of the clamping plate to fit against the side wall of different length models of display screens within a small range, thereby limiting the movement of the display screen and further improving the applicability of the overall mechanism for fixing and using the display screen, as well as improving the installation stability of the display screen.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A splicing LED display screen fixing device according to the technical solution of this application, by providing hollow tubes on the sides of both the fixed baffle and the second vertical plate, and pushing blocks at both ends of the sides of the fixed baffle and the first vertical plate, and vertically movable limiting blocks inside the sides of the fixed baffle and the second vertical plate, allows the length of the overall mechanism to be adjusted according to the width of the display screen when it is needed to store and fix it. With the cooperation of the limiting blocks and the pushing blocks, the limiting blocks return to their original position and their sides contact the sides of the pushing blocks to abut and limit them, thereby ensuring the stability of the connection extension of the two sets of fixed baffles. Subsequently, combined with the same connection and transmission steps of the first vertical plate and the second vertical plate, after the length of the display screen fixing mechanism is extended, the first vertical plate and the second vertical plate can still splice and seal both ends of the sides of the fixed baffle, thereby ensuring that the first vertical plate, the second vertical plate and the fixed baffle can be quickly spliced ​​together, thereby changing the fixed area of ​​the overall mechanism within a large range, ensuring that it can be used for fixing and installing display screens of different lengths and models.

[0017] 2. The splicing LED display screen fixing device of this application has adjusting bolts screwed into both ends of the first and second vertical plates. When the adjusting bolts are turned, the clamping plate moves horizontally between the sides of the fixed baffle. Within a small range, the side of the clamping plate can fit against the side wall of the display screen of different lengths and models, and perform abutment and limit treatment on the display screen. This further improves the applicability of the overall mechanism for fixing the display screen and improves the installation stability of the display screen. Attached Figure Description

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: a splicing LED display screen fixing device, wherein a first vertical plate 11 and a second vertical plate 12 are detachably installed on both ends of the side of the fixing baffle 1, and hollow tubes 22 are fixedly installed on both the outer ends of the fixing baffle 1 and both ends of the side of the second vertical plate 12.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each hollow tube 22 has a movable plate 23 slidably installed inside it. Each movable plate 23 has a movable rod 27 vertically fixedly installed at the middle of its side. The movable rod 27 is slidably inserted into the side of the hollow tube 22 and extends from the inside of the hollow tube 22 to its outside. The outer side of the movable rod 27 is movably sleeved with a push spring 26, and the two ends of the push spring 26 are respectively movably attached to the outer wall of the movable plate 23 and the inner wall of the hollow tube 22. A fixed rod 24 is vertically fixedly installed at the middle of its side. A limit block 25 is fixedly installed at the bottom of the fixed rod 24. The limit block 25 is movably installed inside the mounting groove 28. The two ends of the first vertical plate 11 near the fixed baffle 1 and the two ends of the fixed baffle 1 near the second vertical plate 12 are horizontally fixed with connecting rods 2. Each connecting rod 2 has a push block 21 fixedly installed at the top of its side. The vertical cross-section of the push block 21 and the limit block 25 are both right-angled triangles.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the middle of the side of the first vertical plate 11 and the second vertical plate 12 are both threadedly connected to adjusting bolts 3. The top of the side of the adjusting bolt 3 is rotatably mounted with a retaining plate 31 through a bearing. Each retaining plate 31 has a guide rod 32 fixedly installed at both ends of its side. The guide rod 32 is slidably inserted into the side of the first vertical plate 11 and the second vertical plate 12. The vertical cross section of the guide rod 32 is T-shaped. The first vertical plate 11 and the second vertical plate 12 have corresponding grooves at both ends of their sides. The guide rod 32 is slidably inserted into the groove.

[0025] During operation, when the LED display screen needs to be fixed, select the appropriate number of fixing baffles 1 according to the length and model of the display screen. Align the sides of two sets of fixing baffles 1 and push them continuously. This allows the pushing block 21 of one set of fixing baffles 1 to be pushed and inserted into the mounting groove 28 of the other set of fixing baffles 1. During the movement, the pushing block 21 can contact the inclined surface of the limiting block 25 and abut it. This allows the limiting block 25 to move vertically synchronously with the horizontal movement of the fixing baffles 1. Under the connecting transmission action of the fixing rod 24, the limiting block 25, under the abutment force of the pushing block 21, can drive the movable plate 23 to move vertically synchronously inside the hollow tube 22. This can compress the pushing spring 26, causing it to deform and have a restoring pushing force. With the continuous pushing of the fixing baffles 1, the pushing block 21 moves horizontally synchronously inside the mounting groove 28 until it is pushed... After the moving block 21 moves away from the side of the limiting block 25 and loses its resistance to the limiting block 25, the limiting block 25, under the action of the pushing spring 26, can move back to its original position, so that the side of the limiting block 25 and the side of the pushing block 21 come into contact, realizing the horizontal connection of the two adjacent sets of fixed baffles 1. Then, using the same connecting mechanism, the first vertical plate 11 and the second vertical plate 12 are installed on the left and right sides of the fixed baffle 1 respectively. Then, the display screen to be installed is placed between the fixed baffle 1, the side of the first vertical plate 11 and the side of the second vertical plate 12. Then, the adjusting bolt 3 is turned, so that the abutting plate 31, under the guiding and limiting action provided by the guide rod 32, can move the two sets of abutting plates 31 synchronously towards each other until the side of the abutting plate 31 is fully attached to the outer wall of the display screen, thus performing the abutting and limiting action on the display screen, and the installation and fixing of the display screen is completed.
