[0020] In the description of the utility model, it should be pointed out that, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; It can be mechanically connected, or it can be electrically connected; It can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0021] Please see Figures 1 to 6 ​​The utility model discloses an industrial control type display screen's mounting structure, including upper frame 1, lower frame 2 and optical screen subassembly 3, the side of upper frame 1 is provided with at least one clamping groove 11, the outer surface of the side of lower frame 2 is provided with the clamping convex 21 of the matching number of clamping groove 11, the one end of the opposite two sides of lower frame 2 is bent inward, the bottom surface and the side of lower frame form the accommodation groove 22, optical screen subassembly 3 is arranged in accommodation groove 22.

[0022] In the above embodiment, the four sides of the upper frame 1 are designed with at least one clamping groove 11, which is used for precise docking with the corresponding components of the lower frame 2. The outer surface of the side of the lower frame 2 is provided with a clamping convex 21 which is completely matched in number with the clamping groove 11 of the upper frame 1. Through the embedding of the clamping convex 21 and the clamping groove 11, the stable connection of the upper frame 1 and the lower frame 2 is realized. The two opposite sides of the lower frame 2 are bent inward at one end to form a folded edge, which together with the bottom surface forms an accommodation groove 22 for accommodating the optical screen subassembly 3. When the optical screen subassembly 3 works in a high temperature environment, due to the physical property of thermal expansion and contraction of materials, the screen body will expand to a certain extent. At this time, the folded edge structure of the lower frame 2 will open to adapt to the expansion change of the optical screen subassembly 3. In the process of opening the folded edge structure, it always maintains close contact with the side of the optical screen subassembly 3, thereby ensuring the stability and limiting fixation of the optical screen subassembly 3 after expansion. This design not only avoids the displacement or deformation of the screen body caused by expansion, but also reserves enough space to adapt to the natural expansion of the screen body, ensuring the normal work and service life of the display screen in a high temperature environment.

[0023] Please refer to Figures 1 to 6 In the above embodiment, the front view of the accommodation groove 22 is a rectangular shape with notches 221 at two corners.

[0024] In the above embodiment, the rectangular shape provides a stable support basis, ensuring that the optical screen can be placed horizontally and uniformly in the groove. The notches 221 at the two corners have a dual role. First, they serve as a guide structure during installation, facilitating the accurate and rapid positioning of the optical screen subassembly 3 into the groove. Second, in the case of thermal expansion, these notches 221 can act as a buffer area, allowing the optical screen subassembly 3 to freely expand within a limited range without being completely constrained, thereby protecting the screen body from stress concentration or damage. This design takes into account the convenience of installation and the reliability of use.

[0025] Please refer to Figures 1 to 6 In the above embodiment, the front view of the notch 221 is a rectangular shape.

[0026] In the above embodiment, the rectangular notch 221 provides clear guidance for the precise installation of the optical screen assembly 3, ensuring that the assembly can be smoothly and accurately embedded into the installation groove 22. At the same time, this shape also optimizes the mechanical properties of the notch 221, enabling it to withstand certain external forces without being easily deformed. When the optical screen assembly 3 undergoes thermal expansion due to high temperature environment, the rectangular notch 221 can serve as an effective buffer area,

[0027] Please refer to Figures 1 to 6 In the above embodiment, a gap groove 12 is provided between the two side edges of the upper frame 1.

[0028] In the above embodiment, the design of the gap groove 12 makes the four side edges of the upper frame 1 not directly connected physically, but each independently and with a certain interval. This design allows each side edge to displace to a certain extent along its outer side direction under the action of thermal expansion or other external forces, to adapt to the size change of the material due to temperature change. Therefore, when the entire display screen structure works in a high temperature environment, if the lower frame 2 expands, its expansion force will not be directly hindered by the side edges of the upper frame 1, but can make the side edges of the upper frame 1 move outward correspondingly through the existence of the gap groove 12, thereby maintaining the balance and stability of the entire structure and avoiding internal stress concentration or structural damage caused by expansion.

[0029] Please refer to Figures 1 to 6 In the above embodiment, the lower frame 2 is provided with threaded holes 23, and the upper frame 1 is provided with retention holes 13, wherein the threaded holes 23 and the retention holes 13 are positionally coincident when the upper frame 1 is coupled with the lower frame 2.

[0030] In the above embodiment, the lower frame 2 is provided with threaded holes 23, which are accurately arranged according to the designed position for subsequent cooperation with fasteners. At the same time, the upper frame 1 is correspondingly provided with retention holes 13, which are matched in shape and size with the threaded holes 23 of the lower frame 2, ensuring that the two can be accurately aligned when coupled. When it is necessary to fixedly connect the upper frame 1 and the lower frame 2, by passing the fastener (such as a screw) through the retention hole 13 of the upper frame 1 and screwing it into the threaded hole 23 of the lower frame 2, the stable coupling of the two can be achieved.

[0031] Please refer to Figures 1 to 6 In the above embodiment, the number of threaded holes 23 and the number of retention holes 13 are at least one, and the number of the two is consistent.

[0032] In the above embodiment, when the upper frame 1 and the lower frame 2 are coupled, pressure can be uniformly distributed through multiple fastening points, enhancing the overall connection strength and stability.

[0033] Please refer to Figures 1 to 6In the above embodiment, the upper frame 1 and the lower frame 2 are both made of iron.

[0034] In the above embodiment, the upper frame 1 and the lower frame 2 are both made of iron.

[0035] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed in the above preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belong to the scope of the present application.
