Description

Technical Field

[0001] The present invention relates to the technical field of seamless matrix, and in particular to a multi-screen splicing hybrid seamless matrix. Background Art

[0002] With the rapid development of the construction of industry equipment systems and informatization systems, achieving secure sharing, fast exchange, and rapid analysis of data has become a necessary requirement for monitoring, conferencing, and command and dispatch. The integration of various data including computer network data, wired data, wireless data, GIS geographic information management, image processing data, etc. can achieve the most perfect application effect through a high-definition hybrid matrix.

[0003] Currently, to achieve a multi-screen matrix to meet the various requirements in the background art, multiple display screens need to be set up, which is rather troublesome to use. To facilitate the splicing of multiple display screens, the existing Chinese patent document CN202120273047.0 discloses a multi-screen splicing hybrid seamless matrix, including a base. An open-ended fixed cylinder is fixedly installed on the upper end surface of the base. At the same time, internal threads are provided on the inner wall of the port of the open-ended fixed cylinder. A column is threadedly connected inside the open-ended fixed cylinder. At the same time, a U-shaped frame is fixedly installed on the column. A display screen structure is fixedly installed on the inner side of the port of the U-shaped frame through fastening screws. The display screen structure includes a casing, a cover, and a display component. By setting a number of installation areas, circuit boards can be installed in the installation areas as needed, and then multiple display components can be correspondingly installed on the cover and electrically connected to the circuit boards. Compared with the traditional method of setting multiple display screens, this design is not only convenient for splicing into multiple display screens to achieve a multi-screen matrix and meet various requirements in the background art, but also convenient for installation, disassembly, and maintenance. The display components in the above solution are mainly adhered inside the cover by epoxy resin glue. Since epoxy resin glue has a very strong adhesive force, it is usually rather difficult to disassemble the adhered display components when a single display component needs to be replaced or repaired. Therefore, the method of adhesion with epoxy resin glue will result in low efficiency in maintaining a single display component. Summary of the Invention

Locking holes 3026 adapted to the second studs 3022 are formed on the limiting column 305. The single-group display component 102 can be locked and fixed through the second connecting member 302, so as to ensure the connection strength between the display component 102 and the circuit board 103, and also replace the fixing method by epoxy resin bonding, which is beneficial to quickly splicing multiple groups of display components 102 into a seamless matrix; Among them, the linkage member 303 includes a first bevel gear 3031, a second bevel gear 3032, a first rotating shaft 3033, a first transmission gear 3034 and a second transmission gear 3035.

The linkage between the first connecting member 301 and the second connecting member 302 is further realized through the linkage member 303.

[0024] Specifically, when installing multiple groups of display components 102, first snap the multiple groups of display components 102 into the corresponding rectangular grooves on the machine cover 101 through the sealing ring. Then place the corresponding circuit board 103 on the fixed seat 304 so that the docking holes 3016 and the first docking posts 3014 are aligned. Then align and place the machine cover 101 on top of the machine shell 1. At this time, the bottom of the limit post 305 is positioned within the U-shaped block 306. After that, start the control unit 4 to work. The control unit 4 drives all the linkage rods 3037 to rotate together. The linkage rod 3037 drives the first spiral gear 3036 to rotate. The first spiral gear 3036 drives the second spiral gear 3039 to rotate. The second spiral gear 3039 drives the sleeve 3021 to rotate.

One end of the fastening unit 7 is in transmission connection with the second rotating shaft 401.

[0026] Specifically, during installation, the second rotating shaft 401 is driven to rotate by the micro reduction motor 406.

The worm wheel 403 drives the third transmission gear 404 to rotate, the third transmission gear 404 drives the fourth transmission gear 405 to rotate, and the fourth transmission gear 405 drives the linkage rod 3037 to rotate, thereby realizing the operation of the linkage member 303.

Both ends of the rotating valve plate 601 are rotatably connected in the through groove through the third rotating shaft 602. The through groove is adapted to the rotating valve plate 601. The fourth helical gear 506 is fixedly sleeved with the third rotating shaft 602.

[0032] Specifically, a controller and a temperature sensor are arranged in the casing 1 to monitor the working temperature inside the casing 1. When the temperature inside the casing 1 is detected by the temperature sensor to exceed the set value, the micro reduction motor 406 can be started to work through the controller. It should be noted that the output end of the micro reduction motor 406 here is connected to one group of the second rotating shafts 401 without the worm 402, and the micro reduction motor 406 can be controlled to rotate forward and backward frequently for 5 - 10 turns. In this way, through the speed increasing effect of the fifth transmission gear 501, the first speed increasing gear 502 and the second speed increasing gear 503, the fourth helical gear 506 will rotate forward and backward more than 10 turns, and then drive the third rotating shaft 602 to rotate forward and backward multiple turns, so that the rotating valve plate 601 rotates multiple turns. When the rotating valve plate 601 rotates, it will frequently open the bottom of the casing 1, playing an effect of fanning the air, accelerating the air flow rate at the bottom of the casing 1, and thus quickly discharging the hot air flow inside the casing 1 from the heat dissipation holes. Compared with the existing heat dissipation method using several heat dissipation fans, because the heat dissipation fans have to work when the display screen structure is used, and still use the heat dissipation holes for heat dissipation within the normal temperature range, this method can save more electric energy and has less power consumption.

[0033] In addition, a soft rubber layer is provided on the outer side of the rotary valve plate 601. When the rotary valve plate 601 does not rotate, the soft rubber layer can seal the through groove. A plurality of blades 603 are fixed on both the inner and outer sides of the rotary valve plate 601, so that the flow of air can be further accelerated when the rotary valve plate 601 rotates.
