[0006] Furthermore, the engaging mechanism includes elastic sleeves connected to the four corners of the inner side of the rear cover plate, and the inner diameters of the elastic sleeves are slightly smaller than the diameter of the protruding column.

[0007] Furthermore, the screwing mechanism includes a rectangular frame fixedly sleeved on the outer peripheral sides of the display panel and the rear cover plate, and connecting holes are opened through the four corners of the two rectangular frames, and combined bolts are matched and connected in the connecting holes.

[0008] Further, the combined bolt consists of a head, a threaded rod and a nut, wherein the head is located on the display panel side; in addition, the length of the rod is equal to the sum of the depths of the two connection holes plus the thickness of the nut.

[0009] Furthermore, an elastic gasket can be sleeved on the outer peripheral side of the rod portion, and the gasket is located between the nut and the rectangular frame located at the rear.

[0010] Furthermore, a protrusion is fixedly connected to the middle of the front side of the head, and the protrusion serves as a leveraging structure to replace the screwdriver.

[0011] Technical effect: In the utility model, the rear cover plate can be engaged with the boss passing through the through hole through the action of the engaging mechanism, so that the rear cover plate and the display panel are initially engaged and connected. After this engaging connection, the main board has been covered between the two. Then, the two are further fixed by the action of the screwing mechanism. Because the screwing mechanism is only connected at the four corners of the two and can be manually removed, it is more convenient to disassemble than the existing large number of bolt structures.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] The quick-detachable industrial display driver motherboard provided in this specific embodiment is as follows: Figure 1 and Figure 2As shown, it includes a main component and a quick-release component, wherein: the main component includes a display panel 1, a main board 2 and a rear cover 3, a receiving groove is provided on the back of the display panel 1, and the four corners of the receiving groove are connected with bosses 4; at the same time, the four corners of the main board 2 are provided with through holes 5 for passing the bosses 4; the quick-release component includes a snap-fit ​​mechanism 6 arranged on the inner side of the rear cover 3 for snap-fitting and connecting with the bosses 4 passing through the through holes 5, and the snap-fit ​​mechanism 6 includes elastic sleeves 601 connected to the four corners of the inner side of the rear cover 3, and the inner diameters of these elastic sleeves 601 are slightly smaller than the diameter of the boss 4; at the same time, a screw-fit mechanism 7 for screwing at the four corners and being manually removed is also provided between the display panel 1 and the rear cover 3, as shown in FIG. Figure 3 and Figure 4 As shown, the screwing mechanism 7 includes a rectangular frame 701 fixedly sleeved on the outer peripheral sides of the display panel 1 and the rear cover 3, and the four corners of the two rectangular frames 701 are penetrated with connection holes 702, and the connection holes 702 are matched with combined bolts 703. In this way, the rear cover 3 can be engaged with the protrusion 4 passing through the through hole 5 through the action of the snap-fit ​​mechanism 6, so that the rear cover 3 and the display panel 1 are preliminarily snap-fitted and connected. After this snap-fit ​​connection, the main board 2 has been covered between the two, and then the two are further fixed through the action of the screwing mechanism 7. Because the screwing mechanism 7 is only connected at the four corners of the two and can be manually removed, it is more convenient to disassemble compared with the existing large number of bolt structures.

[0020] The above-mentioned combined bolt 703 consists of a head, a rod with threads and a nut. For the sake of structural beauty, on the one hand, its head is preferably located on the side of the display panel 1; on the other hand, the length of the rod is equal to the sum of the depths of the two connecting holes 702 plus the thickness of the nut, that is, after the nut is connected, the rod is completely covered without any protruding parts. In addition, in order to avoid the problem of thread slippage, an elastic gasket can be sleeved on the outer peripheral side of the rod, and the gasket is located between the nut and the rectangular frame 701 located at the rear. On this basis, it is worth mentioning that a protrusion 8 is fixedly connected in the middle of the front side of the head, and the protrusion 8 is conveniently twisted manually as a lever structure, instead of using a screwdriver for disassembly and assembly.

[0021] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
