Description

Technical Field

[0001] This utility model relates to the field of LED large screen technology, specifically to an interface control device for LED splicing large screen. Background Technology

[0002] The existing LED splicing screen is a device that splices multiple LED displays together to form a large screen display. In practical use, LED splicing screens can provide advantages such as high brightness, high contrast, high resolution, and clear display effects in various lighting environments, and are therefore widely used, such as concerts, sports broadcasts in stadiums, press conferences, conference speeches, etc.

[0003] Currently, in the specific installation process of LED video wall displays, in order to ensure the overall aesthetics, the interface control devices used are mostly embedded in the wall. However, the existing installation structure of the interface control devices is mostly a fixed bracket located at the front end of the structure. If there is a large deviation between the depth of the clearance groove in the wall and the length of the interface control device, it is easy to cause a large connection gap between the bracket and the wall, resulting in a significant decrease in installation stability. Therefore, in order to solve the above problems, this application will provide an LED video wall display interface control device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an LED splicing screen interface control device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an LED splicing screen interface control device, including a wall and an interface control device body. The wall is provided with a clearance groove for the interface control device body to be nested and installed. A first half-combination frame plate and a second half-combination frame plate are slidably connected to the two sides of the front end of the interface control device body. The top and bottom of one side of the first half-combination frame plate are provided with a storage groove and a step groove, and the step groove and the storage groove are connected. An adjustment plate is snapped into the inside of each of the two storage grooves. One end of each of the two adjustment plates is fixedly connected to the top and bottom of one side of the second half-combination frame plate, and a first threaded hole is opened in the middle of each of the two adjustment plates, which is connected to the space of their respective step grooves. A first limiting screw that can be screwed into the first threaded hole is installed inside the two step grooves.

[0006] The other side of the first half-combination frame plate and the other side of the second half-combination frame plate are provided with mounting sleeves installed on the front end of the wall, and a transition connection structure is installed between the mounting sleeves and the corresponding first half-combination frame plate or the corresponding second half-combination frame plate.

[0007] Preferably, the interface control device body has sliding grooves on both sides, and a slide rail fixed to the inner wall of the other side of the first half-combination frame plate or the other side of the second half-combination frame plate is engaged in the sliding groove. The slide rail ensures the stability of the first half-combination frame plate and the second half-combination frame plate during subsequent movement and adjustment.

[0008] Preferably, the front end of the wall is provided with a second threaded hole that is aligned with the internal space of the mounting sleeve, and the mounting sleeve and the wall can be disassembled and installed by screws locking the second threaded hole, which facilitates subsequent disassembly and maintenance.

[0009] In this preferred embodiment, spring plates are fixedly connected to the inner walls of one side of each of the two storage slots, and one end of each of the two spring plates is fixedly connected to one end of each of the two adjusting plates. The spring plates are used to link the adjusting plates so that the first half of the combined frame plate and the second half of the combined frame plate can be connected as a whole while maintaining the function of the first half of the combined frame plate and the second half of the combined frame plate moving and making room for each other.

[0010] In particular, the top and bottom surfaces of the interface control device body are provided with several guide grooves, and the guide grooves are all in a through state. The guide grooves further expand and connect the fitting gap space between the interface control device body and the wall clearance groove with the usage environment, thereby creating favorable conditions for the self-heating of the interface control device body during subsequent operation.

[0011] Selectedly, both of the aforementioned transition connection structures include a support sleeve, one end of which is fixedly connected to the side of the interface control device body. A transition shaft is snapped into the inside of the support sleeve, and one end of the transition shaft is fixed to the side of the corresponding first half-combination frame plate or the side of the corresponding second half-combination frame plate.

[0012] The transition shaft has a positioning hole on its middle surface, and the support sleeve has a clearance hole aligned with the positioning hole in its middle. The positioning hole and the clearance hole form a constraint space, and a T-shaped rod is engaged within the constraint space. A compression spring is fitted on the outer side of one end of the T-shaped rod, and the two ends of the compression spring are respectively fixedly connected to the surface of the support sleeve and the end surface of one end of the T-shaped rod. The transition connection structure ensures a stable connection between the mounting sleeve and the first half of the combined frame plate or the second half of the combined frame plate, while also providing conditions for rotation of the mounting sleeve.

[0013] Preferably, an internally threaded sleeve is fitted on the outer side of one end of the T-shaped rod and fixed to the surface of the support sleeve. The inner side of the middle part of the internally threaded sleeve is connected to a second limiting screw that can compress and limit the T-shaped rod. The combination of the internally threaded sleeve and the second limiting screw is used to press and limit the T-shaped rod in the idle state.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model adapts to the installation structure by combining a first half-combination frame plate, a second half-combination frame plate, a storage groove, a step groove, and an adjustment plate. After being combined with two transition connection structures and two mounting sleeves to form two sets of positioning structures, the front end positions of the first half-combination frame plate and the second half-combination frame plate on the interface control device body can be adjusted according to the actual situation after the interface control device body is embedded in the wall, until the two sets of positioning structures can be assembled in close contact with the wall, ensuring the stability of the overall device installation while solving the problems existing in the prior art.

[0016] 2. The two positioning structures set in this utility model have two internal transition connection structures with rotation adjustment function. Therefore, even in the case that there is no clearance groove in the wall in the actual environment, the two positioning structures can be adjusted relative to the interface control device body to stably install the interface control device body on the wall in a planar fit.

[0025] 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.

[0026] Please see Figure 1-5 An interface control device for an LED splicing screen includes a wall 1 and an interface control device body 2. The wall 1 is provided with a clearance groove for the interface control device body 2 to be nested and installed. A first half-combination frame plate 3 and a second half-combination frame plate 4 are slidably connected to the two sides of the front end of the interface control device body 2, respectively. The top and bottom of one side of the first half-combination frame plate 3 are provided with a storage groove 5 and a step groove 6, and the step groove 6 is spatially connected to the storage groove 5. An adjustment plate 7 is snapped into the interior of each of the two storage grooves 5, and one end of each of the two adjustment plates 7 is fixedly connected to the top and bottom of one side of the second half-combination frame plate 4, respectively. The middle of each of the two adjustment plates 7 is provided with a first threaded hole that is spatially connected to the corresponding step groove 6, and the interior of each of the two step grooves 6 is fitted with a first limiting screw 8 that can be screwed into the first threaded hole.

[0027] On the other side of the first half-combination frame plate 3 and on the other side of the second half-combination frame plate 4, there are mounting sleeves 11 installed on the front end of the wall 1, and a transition connection structure 10 is installed between the mounting sleeves 11 and the corresponding first half-combination frame plate 3 or the corresponding second half-combination frame plate 4;

[0028] The interface control device body 2 has sliding grooves on both sides, and a slide rail 13 fixed to the inner wall of the other side of the first half-combination frame plate 3 or the second half-combination frame plate 4 is engaged in the sliding groove. The slide rail 13 ensures the stability of the first half-combination frame plate 3 and the second half-combination frame plate 4 during subsequent movement and adjustment. The front end of the wall 1 has a second threaded hole aligned with the internal space of the mounting sleeve 11, and the mounting sleeve 11 and the wall 1 can be disassembled and installed by screws and the screw lock of the second threaded hole, which facilitates subsequent disassembly and maintenance.

[0029] Spring plates 9 are fixedly connected to the inner walls of one side of the two storage slots 5, and one end of each spring plate 9 is fixedly connected to one end of each adjustment plate 7. The spring plates 9 are used to link the adjustment plates 7 to make the first half of the combined frame plate 3 and the second half of the combined frame plate 4 integrated and used at the same time to maintain the function of the first half of the combined frame plate 3 and the second half of the combined frame plate 4 moving and making room.

[0030] Specific usage of this embodiment:

[0031] After the interface control device body 2 is fitted into the pre-set clearance groove inside the wall 1, the first half-combination frame plate 3, the second half-combination frame plate 4, and related structures on the surface of the interface control device body 2 can be adjusted and adapted according to the actual fitting situation of the interface control device body 2. That is, if the interface control device body 2 protrudes forward too much and the connection gap between the mounting bracket 11 and the wall 1 is large, the adjustment and adaptation can be made as follows:

[0032] Tighten the first limiting screw 8 and temporarily move it away from the step groove 6 to release the positioning constraint of the first limiting screw 8 on the adjusting plate 7. Then, directly push the first half-assembly frame plate 3 and the second half-assembly frame plate 4. At this time, the adjusting plate 7, with the cooperation of the spring plate 9, can provide elastic movement between the first half-assembly frame plate 3 and the second half-assembly frame plate 4, thereby releasing the relative clamping and fixing state of the first half-assembly frame plate 3 and the second half-assembly frame plate 4. After the mounting sleeve 11 associated with the first half-assembly frame plate 3 and the mounting sleeve 11 associated with the second half-assembly frame plate 4 are both in contact with the surface of the wall 1, press the first half-assembly frame plate 3 and the second half-assembly frame plate 4, and then reset and lock the first limiting screw 8 so that the first limiting screw 8 re-contacts the middle inner wall of the step groove 6, restoring the positioning constraint on the adjusting plate 7, thereby ensuring the stability of the first half-assembly frame plate 3 and the second half-assembly frame plate 4 on the interface control device body 2.

[0033] Please see Figure 1 , Figure 4 The top and bottom surfaces of the interface control device body 2 are provided with several guide grooves 12, and the guide grooves 12 are all in a through state. The guide grooves 12 further expand and connect the fitting gap space between the interface control device body 2 and the clearance groove in the wall 1 with the usage environment, thereby creating favorable conditions for the self-heating of the interface control device body 2 during subsequent operation.

[0034] Specific usage of this embodiment:

[0035] Considering that the interface control device body 2 will generate a lot of heat during long-term use, multiple guide grooves 12 are added to the surface of the interface control device body 2. Subsequently, after the working heat of the interface control device body 2 heats the air between the interface control device body 2 and the clearance groove, the cold air in the environment will be guided by the multiple guide grooves 12 and circulate with the hot air between the interface control device body 2 and the clearance groove, thereby accelerating the self-heating speed of the interface control device body 2.

[0036] Please see Figure 6-7Both transition connection structures 10 include a support sleeve 101. One end of the support sleeve 101 is fixedly connected to the side of the interface control device body 2. A transition shaft 102 is snapped into the inside of the support sleeve 101, and one end of the transition shaft 102 is fixed to the side of the corresponding first half-combination frame plate 3 or the side of the corresponding second half-combination frame plate 4.

[0037] A positioning hole is provided on the middle surface of the transition shaft 102, and a clearance hole aligned with the positioning hole is provided on the middle part of the support sleeve 101. The positioning hole and the clearance hole form a constraint space, and a T-shaped rod 103 is snapped into the constraint space. A compression spring 104 is fitted on the outer side of one end of the T-shaped rod 103. The two ends of the compression spring 104 are respectively fixedly connected to the surface of the support sleeve 101 and the end surface of one end of the T-shaped rod 103. The transition connection structure 10 ensures that the mounting sleeve 11 is stably connected to the first half of the combined frame plate 3 or the second half of the combined frame plate 4, while also providing conditions for the mounting sleeve 11 to rotate.

[0038] An internally threaded sleeve 105 is fitted on the outer side of one end of the T-shaped rod 103 and fixed to the surface of the support sleeve 101. The inner side of the middle part of the internally threaded sleeve 105 is connected to a second limiting screw 106 that can compress and limit the T-shaped rod 103. The combination of the internally threaded sleeve 105 and the second limiting screw 106 is used to press and limit the T-shaped rod 103 in the idle state.

[0039] Specific usage of this embodiment:

[0040] Considering the absence of clearance grooves in the wall in actual environments, the installation of the interface control device body 2 will be changed to a flat installation, as detailed below:

[0041] Tighten the second limiting screw 106 inside one of the transition connection structures 10 to move the second limiting screw 106 away from the internal threaded sleeve 105, thereby releasing the pressure limiting on the T-shaped rod 103. Next, tighten the mounting sleeve 11 to rotate and adjust the transition shaft 102 until the mounting sleeve 11 changes from the state of the front end of the parallel interface control device body 2 to the state of the front end of the vertical interface control device body 2. Then, reset the second limiting screw 106 to press the T-shaped rod 103 back into the positioning hole, thereby limiting the transition shaft 102 and the support sleeve 101 again. Similarly, adjust the other transition connection structure 10 according to the above steps. After both mounting sleeves 11 are perpendicular to the front end of the vertical interface control device body 2, the interface control device body 2 can be longitudinally attached to the surface of the wall 1. Then, use the two mounting sleeves 11 and the existing screws to install it in the designated position on the wall 1.
