Their design aims to simplify installation, improve splicing accuracy, and facilitate later maintenance. Typically, these splicing devices are suitable for large display systems such as advertising screens, stage displays, and monitoring systems.
[0003] Most existing LED screen splicing devices assemble LED screen modules using multiple splicing frames. However, traditional splicing frames typically require numerous tools and bolts for splicing and fixing, resulting in a cumbersome and inefficient installation process. Furthermore, this splicing method suffers from insufficient structural strength, making it prone to displacement under external impact, affecting overall stability. Additionally, LED screens often generate significant heat during use; poor heat dissipation can negatively impact normal operation after prolonged use.
[0004] Therefore, in order to address the problems of cumbersome installation and poor heat dissipation of existing LED screen splicing devices, a modular rapid splicing device for LED displays has been developed. By adding multiple stable connection structures and air-cooling heat dissipation structures to the LED screen splicing device, the convenience of splicing LED screens can be effectively improved, and the heat dissipation of LED screens during use can be guaranteed.

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please see Figures 1-7This utility model provides an embodiment: a modular rapid splicing device for LED displays, including an LED screen body 1 and a back frame 13, and also including a first connecting frame 2, a second connecting frame 3, a connecting buckle plate 5, and a cooling fan 19. The back frame 13 is fixedly connected to the rear end of the LED screen body 1. Several sets of heat dissipation grooves 14 are formed through the four edges of the back frame 13. A second groove 15 is formed at the rear end of the back frame 13. A fan mounting plate 4 is fixedly connected to the inner wall of the rear end of the second groove 15. A cooling fan 19 is installed through the center of the rear end of the fan mounting plate 4. A left fan 19 is fixedly connected to the upper end of the LED screen body 1. The LED screen body 1 has symmetrically distributed connecting plates 5 on the right and symmetrically distributed connecting slots 12 at the lower end. The LED screen body 1 has a second connecting frame 3 and a first connecting frame 2 fixed to the left and right ends respectively. The inner wall edge of the first connecting frame 2 has a protrusion 7 fixed to it. The upper and lower ends of the first connecting frame 2 are provided with first connecting teeth 6. The front and rear ends of the second connecting frame 3 are provided with first grooves 9. The upper and lower ends of the first grooves 9 are provided with second connecting teeth 10. The front and rear ends of the first grooves 9 are provided with grooves 11. The left and right ends of the LED screen body 1 have symmetrically distributed mounting posts 18 and mounting slots 8 respectively.
[0028] By using the first connecting frame 2 and the protrusion 7 in conjunction with the second connecting frame 3 and the groove 11, and by using the connecting buckle plate 5 and the connecting buckle slot 12, several sets of LED screen bodies 1 can be stably connected in the left-right and up-down directions. The mounting post 18, in conjunction with the mounting slot 8, and the first connecting tooth 6, in conjunction with the second connecting tooth 10, can help improve the stability of the two sets of LED screen bodies 1 when the first connecting frame 2 and the second connecting frame 3 are connected to each other, and prevent them from falling off when connected to each other, thereby improving the firmness of the left-right connection between the two sets of LED screen bodies 1. The cooling fan 19, in conjunction with the heat dissipation slot 14 on the back frame 13, can efficiently dissipate the heat generated by the LED screen body 1 during operation.
[0029] Please see Figures 3-7In this embodiment, the outer wall of the first connecting frame 2 fits against the inner wall of the first groove 9, and the first connecting tooth 6 meshes with the second connecting tooth 10. Both the first connecting tooth 6 and the second connecting tooth 10 are made of plastic. In use, the first connecting tooth 6 and the second connecting tooth 10 can assist the first connecting frame 2 and the second connecting frame 3 in making a tight connection and reduce the possibility of them falling off during use. The connecting buckle plate 5 is adapted to the connecting buckle groove 12, and the protrusion 7 is adapted to the groove 11. In use, the connecting buckle plate 5 and the connecting buckle groove 12 can assist the assembly of multiple LED screen bodies 1 in the vertical direction. The mounting column 18 is connected to the mounting groove 8. The first connecting frame 2 and the second connecting frame 3 are adapted to each other. During use, the mounting column 18 and the mounting groove 8 can assist the stability and firmness of multiple LED screen bodies 1 when they are assembled left and right. The rear end of the LED screen body 1 is provided with a heat dissipation vent 17. The air outlet of the cooling fan 19 corresponds to the heat dissipation vent 17. During use, the corresponding heat dissipation vent 17 and cooling fan 19 can efficiently dissipate the heat generated by the LED screen body 1 during operation. The heat dissipation groove 14 is connected to the second groove 15. The back frame 13 is in the shape of a frustum. During use, the heat dissipation groove 14 can dissipate the heat generated by the LED screen body 1 during operation.
[0030] Please see Figures 4-7 In this embodiment, a symmetrically distributed handle 16 is fixed to the rear edge of the back frame 13. The handle 16 is located on the left and right sides of the fan mounting plate 4 and the cooling fan 19. When in use, the handle 16 makes it easy for installers to hold the LED screen body 1 for assembly and splicing.
[0031] Before use, hold the handle 16 and install the first connecting frame 2 and the second connecting frame 3 on the multiple LED screen bodies 1 to each other, so that the first connecting frame 2 is installed on the inner wall of the first groove 9 on the second connecting frame 3, and the first connecting teeth 6 and the second connecting teeth 10 made of plastic material are deformed and meshed with each other, increasing the stability of the splicing and fixing of the first connecting frame 2 and the second connecting frame 3. At the same time, the mounting column 18 enters the inner wall of the mounting groove 8 for positioning, so as to stably connect the multiple LED screen bodies 1 in the left and right directions and ensure the strength of their left and right connection.
[0032] Next, the connecting plates 5 on the multiple LED screen bodies 1 are installed into the connecting slots 12 to quickly assemble the LED screen bodies 1 in the vertical direction.
[0033] When the LED screen body 1 is working, the heat generated by the LED screen body 1 can be quickly discharged from the heat dissipation groove 14 by the cooling fan 19, so as to ensure the efficiency of the LED screen body 1 during operation and avoid overheating.
[0034] Through the above steps, the first connecting frame 2 and the protrusion 7 cooperate with the second connecting frame 3 and the groove 11, and the connecting buckle 5 cooperates with the connecting buckle groove 12, so that several groups of LED screen bodies 1 can be stably connected in the left and right and up and down directions. The mounting column 18 cooperates with the mounting groove 8 and the first connecting tooth 6 cooperates with the second connecting tooth 10, which can help improve the stability of the two groups of LED screen bodies 1 when they are connected by the first connecting frame 2 and the second connecting frame 3, and prevent them from falling off when they are connected, thereby improving the firmness of the left and right connection of the two groups of LED screen bodies 1. The cooling fan 19 cooperates with the heat dissipation groove 14 on the back frame 13 to efficiently dissipate the heat generated by the LED screen body 1 when it is working, which solves the problem that the existing LED screen splicing device is relatively cumbersome to install and has poor heat dissipation effect of the LED screen during use.
[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
