Description

Technical Field

[0001] The present application belongs to the technical field of display connection equipment, and more specifically, relates to a module mounting fastener, a mounting workpiece, a module mounting structure and a display device. Background Art

[0002] Light-emitting diode (LED) displays occupy an important position in the field of modern display technology due to their advantages such as wide color gamut, high brightness, large viewing angle, low power consumption and long life.

[0003] During the assembly and installation of LED display screens, the module fixing method is very important. Traditional module fixing methods mainly include bolt fixing and magnetic fixing. Although the bolt fixing method is firm, the disassembly and assembly process is complicated and inconvenient to operate. In addition, the bolts and nuts are prone to rust after long-term use, which increases the difficulty of repair and maintenance.

[0004] Especially in small-pitch LED display screens, due to the small module spacing, the connection and fixation between modules are more critical. At present, most small-pitch LED display screen installation modules are connected to the box using a magnet adsorption structure. Although the magnet is installed inside the module, due to the effect of the magnetic field, there will still be a weak magnetic field on the surface of the module, which will also adsorb metal dust such as iron, nickel, and cobalt. Especially in special environments such as stations, subways, urban rails, and metal processing plants that contain a large amount of iron, nickel, and cobalt dust, the adsorption problem of metal dust is more serious. As the adsorbed metal dust continues to increase, the video playback screen of the LED display screen in a local area is blocked. From a distance, the blocked part will form obvious black spots, which seriously reduces the display effect and service life of the LED display screen. Utility Model Content

[0026] The present application provides a module installation fastener comprising a flange, a first claw flap and a second claw flap.

When the second external structure is inserted between the second claw petals, the second end of each second claw petal is pushed outward under the squeezing action of the second external structure, providing space for the second external structure to be smoothly inserted. Once the second external structure is inserted into place, the elastic potential energy released by the second claw petal will cause the second end of the second claw petal to quickly gather back to the initial position, thereby tightly clamping the second external structure. The module installation fastener of the present application does not require a long thread length, is suitable for installation in thin-walled locations, has a wider range of uses, and has the advantages of easy molding and low production cost.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0050] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] like Figure 1 As shown, the present application provides a module mounting fastener, comprising a flange 1, a first claw 2 and a second claw 3. The flange 1 serves as the basic structure of the entire module mounting fastener, providing support for the first claw 2 and the second claw 3.

[0053] At least two first claws 2 are provided on the first side of the flange 1. The number of the first claws 2 can be two, three, four, etc. The first claws 2 are arranged at intervals from each other along the circumferential direction of the flange 1 to ensure that the force on each first claw 2 is uniform during the installation of the module mounting fastener. The first end of each first claw 2 is connected to the flange 1, and the second end of each first claw 2 can be elastically gathered or separated from each other; when it is necessary to pass through the first external structure (such as a hole, a groove, etc.), the second end of each first claw 2 will be gathered under the pressure of the first external structure to reduce the overall size, so as to pass through the first external structure. Once passing through the first external structure, the elastic potential energy released by the first claw 2 will cause it to quickly separate, and then expand and tighten on the first external structure to ensure that the outer wall of the first claw 2 is tightly engaged with the first external structure, so as to achieve a stable installation of the module mounting fastener.

[0054] At least two second claws 3 are also provided on the second side of the flange 1. The number of the second claws 3 can also be two, three, four, etc. The second claws 3 are arranged at intervals from each other along the circumferential direction of the flange 1, and the first ends of the second claws 3 are connected to the flange 1, and the second ends of the second claws 3 can be elastically gathered together or separated from each other. The second claws 3 look similar to the first claws 2, but the functions are different. The second claws 3 are connected to the second external structure through the inner wall. When the second external structure is inserted between the second claws 3, the second ends of the second claws 3 are pushed outwards under the squeezing action of the second external structure, that is, they are separated from each other, providing space for the smooth insertion of the second external structure. Once the second external structure is inserted into place, the elastic potential energy released by the second claws 3 will cause the second ends of the second claws 3 to quickly gather back to the initial position, thereby tightly clamping the second external structure.

[0055] The module installation fastener of the present application does not require a long thread length, and the first external structure only needs to match the clamping thickness of the first claw 2, which is generally 1.5mm-2mm, and is suitable for installation in thin-walled locations, with a wider range of uses. The module installation fastener of the present application also has the advantages of easy molding and low production cost.

[0056] like Figure 1 As shown, in one embodiment of the present application, the first claw 2 includes a guide portion 21 and a slot portion 22. Specifically, the guide portion 21 is provided at the second end of the first claw 2, and the outer wall of the guide portion 21 is a smooth guide slope, and the guide slopes of each first claw 2 are enclosed to form a guide cone. The existence of the guide cone not only greatly increases the smoothness of the first claw 2 when in contact with the first external structure, effectively preventing the occurrence of bumps, but also has a guiding effect, making the first claw 2 smoother when passing through the first external structure, thereby smoothly achieving the clamping connection.

[0057] At the same time, the slot portion 22 is located at the first end of the first claw 2, and it undertakes the important task of engaging with the external structure. When the second end of the first claw 2 successfully passes through the first external structure, the slot portion 22 will form a tight engagement with the first external structure. It is worth noting that since the guide portion 21 and the flange 1 protrude from both sides of the slot portion 22 respectively, when the slot portion 22 engages with the first external structure, the guide portion 21 and the flange 1 can form an effective stop for the first external structure, preventing the module installation fastener from falling off the first external structure, thereby ensuring the stability and reliability of the module installation fastener.

[0058] like Figure 4 As shown, in one embodiment of the present application, the inner wall of the second claw 3 has a snap protrusion 31, and the snap protrusions 31 of each second claw 3 enclose a snap hole for the second external structure to be snapped. When the second external structure is inserted into the snap hole, the snap protrusion 31 abuts against the second external structure. Each snap protrusion 31 encloses the outer periphery of the second external structure, thereby fixing the second external structure.

[0059] like Figures 1 to 4 As shown, in one embodiment of the present application, the flange 1, the first claw 2 and the second claw 3 are an integrated structure. This integrated structure not only enhances the structural stability of the entire module mounting fastener, but also simplifies the manufacturing process and improves production efficiency.

[0060] In one embodiment of the present application, the flange 1, the first claw flap 2 and the second claw flap 3 are all made of plastic. The plastic material has excellent plasticity, so that the flange 1, the first claw flap 2 and the second claw flap 3 can be precisely molded according to the design requirements, ensuring that the size, shape and performance of each component are in the best state. At the same time, the plastic material also has good elasticity and toughness, so that the first claw flap 2 and the second claw flap 3 can elastically gather or deviate when squeezed by the first external structure and the second external structure respectively, thereby achieving a tight snap connection with the external structure. In addition, the plastic material also has the characteristics of lightness, drop resistance, and corrosion resistance, which enables the module installation fasteners to maintain good performance and stability during transportation, installation and use.

[0061] like Figure 3As shown, the present application provides a mounting workpiece for mounting the module mounting fastener in the above-mentioned embodiment, which can greatly improve the installation convenience and installation efficiency of the module mounting fastener. The mounting workpiece includes a mounting cylinder 4 having a hollow portion. The main function of the hollow portion is to avoid or accommodate the second claw 3 of the module mounting fastener. During the module installation process, the second claw 3 may be subjected to external pressure, resulting in deformation, thereby affecting its normal function. The hollow portion of the mounting cylinder 4 can effectively prevent this from happening, ensuring that the second claw 3 always maintains its original shape and performance. One end of the mounting cylinder 4 is used to abut against the flange 1 of the module mounting fastener. In actual use, the user only needs to abut one end of the mounting cylinder 4 on the flange 1 of the module mounting fastener, and then apply force to press the mounting cylinder 4 in the direction of the first external structure. In this process, each first claw 2 will gather under the pressure of the first external structure, thereby reducing the overall size to pass through the first external structure. Once the guide portion 21 of the first claw flap 2 passes through the first external structure, the first claw flap 2 will quickly return to its original shape, tightly clamping the first external structure on the clamping groove portion 22, thereby achieving a stable installation of the module mounting fastener.

[0062] like Figure 3 , Figure 5 and Figure 6 As shown, the present application provides a module installation structure, including a module base 5, a plug-in component 6, and the module installation fastener in the above embodiment. The module base 5 serves as the basis of the entire installation structure, and is provided with a mounting hole 51. The mounting hole 51 serves as a first external structure adapted to the module installation fastener, providing support for the module installation fastener. The module base 5 can be specifically in the form of a frame, a box, etc., to adapt to different scenarios and needs.

[0063] The plug connector 6 is a key component for connecting the display screen body 7 and the module mounting fastener. One end of the plug connector is connected to the display screen body 7, and the other end is provided with a joint matching the module mounting fastener. The plug connector 6 can be inserted into the module mounting fastener to achieve the connection between the display screen body 7 and the module base 5. The plug connector 6 can be a latch, a plug, etc.

[0064] like Figure 8As shown, in one embodiment of the present application, the module base 5 also includes guide ribs 52, which are arranged in pairs on the periphery of the mounting hole 51, and the height of the guide ribs 52 is greater than the height of the module mounting fastener installed on the mounting hole 51. When the plug-in connector 6 is docked with the module mounting fastener, the guide ribs 52 can assist the plug-in connector 6 to find the position of the module mounting fastener more quickly, so as to guide the installation of the plug-in connector 6 and improve the installation efficiency. In addition, the guide ribs 52 can also play the role of reinforcement ribs, which enhances the rigidity and stability of the module base 5, so that it can remain firm and not deformed when bearing the weight and external forces of components such as the display screen. This reinforcement effect not only extends the service life of the module base 5, but also improves the stability and reliability of the entire module installation structure.

[0065] In one embodiment of the present application, the module base 5 has a plurality of mounting holes 51 so that a plurality of module mounting fasteners can be mounted on the module base 5. The mounting holes 51 are arranged in an array on the module base 5, and the number of module mounting fasteners and plug connectors 6 corresponds to the number of mounting holes 51. By providing a plurality of mounting holes 51, module mounting fasteners and plug connectors 6, the connection points between the display screen body 7 and the module base 5 can be increased, thereby improving the connection stability and reliability of the display screen body 7.

[0066] Compared with the traditional magnetically fixed LED display screen module, the module installation structure of the present application will not cause the problem of adsorbing metal dust, nor will it cause black spots to form on the LED display screen.

[0067] Compared with the traditional bolt-fixed LED display screen module, when installing the module installation structure of the present application, it is only necessary to insert the plug-in 6 into the module base 5 with the module installation fastener installed, and the installation time is only about 2 seconds. When fixing with bolts, it is necessary to twist the bolts or nuts one by one, and it takes about 5 seconds to twist a bolt or nut, and it is not possible to twist multiple bolts or nuts at the same time. The module installation structure of the present application can greatly save installation time and improve installation efficiency.

[0068] like Figure 7 , Fig. 9 and Fig.10 As shown, the present application also provides a display device, which includes a display screen body 7 and the module installation structure in the above embodiment. A plurality of connectors 6 are connected to the back side of the display screen body 7, and a plurality of corresponding mounting holes 51 and module installation fasteners are provided on the module base 5. When the display screen body 7 is installed to the module base 5, the connectors 6 are inserted into the corresponding module installation fasteners to complete the installation of the display screen body 7.

[0069] Since the display device has the module installation structure in the above embodiment, it also has the advantages of the module installation structure in the above embodiment.

[0070] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
