It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the invention.

[0046] like Figure 1 FIG. 2 is a schematic diagram showing a clamping type fixing structure in an embodiment of the present invention. The clamping type fixing structure comprises: a mounting column 11 , a rectangular elastic member 12 and a fixing recess 13 .

[0047] One end of the mounting column 11 is fixed to the first body, and the fixing recess 13 is fixed to the second body.

[0048] Specifically, Figure 1 , Figure 2 as well as Figure 3 As shown, the mounting post 11 includes a limiting portion 111 and a convex portion 112 connected to the limiting portion 111 , and the convex portion 112 is disposed at the other end of the mounting post 11 .

[0049] In a specific embodiment, the limiting portion 111 and the protruding portion 112 of the mounting post 11 are integrally formed.

[0050] A protrusion 113 is provided at one end of the mounting post 11, and a groove 114 is provided to match the clamping slit 122. A fixing hole matching the protrusion 113 is provided on the first body, and the mounting post 11 is fixed to the first body through the protrusion 113. Preferably, the fixing method can be welding connection, and the mounting post 11 is welded to the first body through the protrusion 113.

[0051] It should be noted that the position-limiting portion 111 and the convex head portion 112 are integrally formed, and the mounting post 11 is welded to the first main body via the protrusion 113, which is only one of many embodiments of the present invention. In other embodiments, the position-limiting portion 111 and the convex head portion 112 can also be fixed together by welding, threading, bonding, interference fit, and rivet connection, and the mounting post 11 can also be threaded, bonded, interference fit, and rivet connection with the first main body via the protrusion 113. The present invention does not limit the specific connection method.

[0052] Furthermore, in this embodiment, the mounting column 11 also includes a stop portion 115, and the protrusion 113 is arranged on the outer surface of the stop portion 115. When the mounting column 11 is fixed to the first body through the protrusion 113, the outer side surface of the stop portion 115 is fitted with the first body to facilitate the installation and fixation of the mounting column 11.

[0053] In a preferred embodiment, the material of the mounting column 11 is carbon steel 45 with tin-plated surface, and the burrs are removed. This composite material combines the strength and toughness of carbon steel 45 with the corrosion resistance and good electrical properties of tin, can resist corrosion in a humid environment, is suitable for various complex and harsh environments, and has good weldability, which can support the mounting column 11 to be connected to the first body by welding. Secondly, this composite material can also provide anti-wear protection for the mounting column 11, thereby extending the service life of the mounting column 11.

[0054] The specific structure of the rectangular elastic member 12 is as follows: Figure 1 , Figure 4As shown, it includes two clamping elastic rods 121 connected end to end, the two clamping elastic rods 121 are parallel to each other, and a clamping gap 122 adapted to the other end of the mounting column 11 is provided between the two clamping elastic rods 121 .

[0055] In a specific embodiment, the rectangular elastic member 12 is configured to be arched.

[0056] In a preferred embodiment, the rectangular elastic member 12 is made of 304 spring steel. 304 spring steel is a special steel material with good elasticity, strength and fatigue resistance, and can be used to manufacture various springs and elastic elements, so that the rectangular elastic member 12 can maintain its elasticity and return to its original state after being subjected to loads for a long time or multiple times. In addition, 304 spring steel also has good heat resistance, low temperature resistance and corrosion resistance, which can ensure the service life and reliability of the rectangular elastic member 12.

[0057] The specific structure of the fixing recess 13 is as follows Figure 1 , Figure 5 as well as Figure 6 As shown, it includes a concave cavity 131 . In addition, the inner wall of the concave cavity 131 is correspondingly provided with two bayonet holes 132 , and the two ends of the rectangular elastic member 12 are respectively arranged in the bayonet holes 132 .

[0058] In a specific embodiment, the two bayonet holes 132 are symmetrically arranged and arranged at the lower end of the inner wall of the cavity 131. When the two ends of the rectangular elastic member 12 are installed in the bayonet holes 132, the inner wall of the cavity 131 just contacts the convex part of the rectangular elastic member 12 designed in an arch shape, thereby limiting the position of the rectangular elastic member 12 and preventing the rectangular elastic member 12 from moving randomly.

[0059] In one embodiment, the fixing recess 13 further includes a connecting column 133. The connecting column 133 is disposed at the other end of the fixing recess 13, and the fixing recess 13 is fixed to the second body through the connecting column 133.

[0060] Specifically, the fixing recess 13 is threadedly connected to the second body through the connecting column 133 .

[0061] It should be noted that the fixing recess 13 is threadedly connected to the second body through the connecting column 133, which is only one of many embodiments of the present invention. In other embodiments, the fixing recess 13 and the second body can also be fixed by welding, bonding, interference fit, rivet, etc. The specific fixing connection method is not limited by the present invention.

[0062] In a preferred embodiment, the fixing recess 13 is made of carbon steel 45, and the surface of the material is galvanized and deburred. Carbon steel 45 itself has good mechanical strength and toughness, and surface galvanizing will not significantly affect these basic properties. The galvanized layer can withstand a certain external force, while protecting the internal carbon steel material, and preventing the base steel from being affected by moisture, water and other corrosive environmental factors. Therefore, the fixing recess 13 can have both the mechanical strength of carbon steel 45 and the corrosion resistance of zinc, and can be used in various complex and harsh environments.

[0063] In the present utility model, the clamping fixing structure is mainly used to detachably set the first main body on the second main body, specifically: insert the installation column 11 into the clamping slit 122, the convex head 112 abuts against the clamping elastic rod 121 and applies a certain pressure to the clamping elastic rod 121, the clamping slit 122 is stretched open under the action of pressure, the convex head 112 passes through the clamping slit 122 and is arranged in the concave cavity 131, the clamping elastic rod 121 rebounds and limits the limiting portion 111 to the clamping slit 122, and the first main body is connected to the second main body; pull the installation column 11 out of the clamping slit 122, the convex head 112 stretches the clamping slit 122 and comes out, and the first main body is separated from the second body.

[0064] In a specific embodiment, arc-shaped contact surfaces are respectively provided at the positions where the clamping elastic rod 121 and the mounting column 11 contact each other, so as to facilitate the insertion or extraction of the mounting column 11 into or out of the clamping slit 122 .

[0065] The purpose of the utility model in this embodiment is to achieve a fixed connection between the first body and the second body by fixing the mounting column 11 with the first body, fixing the fixing recess 13 with the second body, and inserting or removing the rectangular elastic member 12 fixed to the fixing recess 13 by the mounting column 11. In specific applications, it can support the fixed connection between the display panel of the display screen and the mounting chassis. On the one hand, compared with the existing method of fixing the display panel and the mounting chassis using mounting holes and screws, the clamping fixing structure of the utility model can not only support rear maintenance, that is, dismantling or installing the display panel from the mounting chassis position behind the display panel, but also support front maintenance, that is, dismantling and installing it from the front position of the display panel, and by inserting or pulling out the mounting column 11 into or out of the clamping gap 122 of the rectangular elastic member 12 with elastic properties, dismantling and installing the display panel is more labor-saving and convenient, with lower maintenance cost and higher efficiency; on the other hand, compared with the existing method of fixing the display panel and the mounting chassis through a magnetic structure, the clamping fixing structure will not be affected in stability by the adsorption of impurities such as iron filings and dust suspended in the air, and can be better adapted to various complex and even harsh environments, thereby improving the adaptability of the clamping fixing structure.

[0066] like Figure 7 As shown, a schematic diagram of a display device in an embodiment of the utility model is shown. The display device comprises: a clamping fixing structure 1 as described in any one of the above items; one or more display modules 2 and a mounting chassis 3 for mounting the display modules.

[0067] It should be noted that the display device provided in the above embodiment and the clamping type fixing structure embodiment belong to the same concept, and the specific implementation process thereof is detailed in the clamping type fixing structure embodiment, which will not be repeated here.
