Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and particularly relates to a locking structure that enables the front and back of a display module to be disassembled and assembled. Background Art

[0002] For the installation of display modules in display screens, there are usually two methods in the industry: rear locking and front-and-rear installation locking. The commonly used front-and-rear locking installation method is usually the elastic sheet pressing method. When locking the display module on the installation box body by the elastic sheet method, it relies on the rotating elastic pressing sheet fixed on the display module. A screwdriver is inserted from the front of the display module to rotate the elastic pressing sheet by a certain angle, and the locking is achieved by the pressure of the elastic sheet. However, the pressure of the elastic sheet is limited, and the locking force is not strong. In environments such as strong wind, slight earthquake, and road vibration, the display module may fall off from the locking structure, resulting in damage to the display screen. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a locking structure that enables the front and back of a display module to be disassembled and assembled. This structure can not only enable the display module to be disassembled and assembled on both its front and back sides, but also the display module and the display screen box body locked by this locking structure have the advantages of high installation strength, high precision, strong weather resistance, and fast disassembly and assembly.

[0004] To achieve the above purpose, the utility model provides a locking structure that enables the front and back of a display module to be disassembled and assembled, including a locking part body for fixedly connecting the display module and the installation box body. It is characterized in that an operation hole is opened on one end face of the locking part body, a countersunk head cavity communicated with the operation hole is opened on the other end face, the radius of the countersunk head cavity is larger than that of the operation hole, a double-headed internal hexagonal bolt is connected in the direction away from the operation hole of the countersunk head cavity, a limiting structure for preventing the double-headed internal hexagonal bolt from detaching from the countersunk head cavity is arranged on one side of the locking part body where the countersunk head cavity is located, and the internal hexagonal hole of the double-headed internal hexagonal bolt is coaxially arranged with the operation hole and the countersunk head cavity;

[0005] A module installation hole for an external tool to disassemble the double-headed internal hexagonal bolt is arranged at one end of the display module corresponding to the double-headed internal hexagonal bolt, and a box body installation hole for an external tool to disassemble the double-headed internal hexagonal bolt is arranged at the other end of the installation box body corresponding to the double-headed internal hexagonal bolt.

[0006] In an embodiment of the present application, the surface of the locking part body facing the operation hole is connected to the display module, and the surface of the locking part body facing the limiting structure is connected to the installation box body.

[0007] In an embodiment of the present application, a circular ring column protrudes along the edge of the operation hole of the locking part body, and the circular ring column penetrates through the module installation hole.

[0008] In an embodiment of the present application, the limiting structure is a cover plate. A cover plate through hole is provided at a position of the cover plate opposite to the double-headed hexagon socket bolt. The cover plate through hole is coaxially arranged and communicated with the counterbore cavity. The cover plate is threadedly connected to the lock body.

[0009] In an embodiment of the present application, the double-headed hexagon socket bolt sequentially includes an annular platform, a connecting portion, and a threaded section. The annular platform is located in the counterbore cavity. The annular platform and the connecting portion are coaxially arranged. The diameter of the connecting portion is less than or equal to the diameter of the cover plate through hole, and the height of the connecting portion is equal to the height of the cover plate.

[0010] By adopting the above technical solutions, the present utility model has the following advantages:

[0011] 1. Users can use tools (such as a hexagon wrench) to rotate the double-headed hexagon socket bolt through the module mounting hole or / and the box body mounting hole to realize the locking and disassembly of the double-headed hexagon socket bolt, and thus realize the disassembly and assembly of the display module from both the front and the back.

[0012] 2. The setting of the limiting structure can prevent the double-headed hexagon socket bolt from disengaging from the counterbore cavity through the operation hole, and at the same time strengthen the connection strength between the display module and the mounting box body, maximizing the locking strength of the display screen. Since the locking strength of the display screen is strengthened, its weather resistance is also improved.

[0013] 3. Through the coaxial arrangement of the module mounting hole, the counterbore cavity, the operation hole, the box body mounting hole and the double-headed hexagon socket bolt, the precision of the entire locking structure is controllable, thereby improving the assembly precision and disassembly and assembly efficiency of the entire display screen.

[0021] In order to make the purpose, technical solution and advantages of 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.

[0022] Reference Figures 1 to 3 , a locking structure that allows a display module 4 to be detachable from both the front and rear sides, comprising a locking body 1 for fixing the display module 4 and the mounting box 5, characterized in that an operating hole 11 is provided on one end face of the locking body 1, and a countersunk cavity 12 connected to the operating hole 11 is provided on the other end face, the radius of the countersunk cavity 12 is larger than the radius of the operating hole 11, a studded hexagon socket bolt 3 is connected to the countersunk cavity 12 in a direction away from the operating hole 11, and a limiting structure is provided on one side of the countersunk cavity 12 of the locking body 1 to prevent the studded hexagon socket bolt 3 from escaping from the countersunk cavity 12, and the hexagonal hole of the studded hexagon socket bolt 3 and the operating hole 11 and the countersunk cavity 12 are all coaxially arranged; one end of the display module 4 corresponding to the studded hexagon socket bolt 3 is provided with a module mounting hole 41 for external tools to remove the studded hexagon socket bolt 3, and the other end of the mounting box 5 corresponding to the studded hexagon socket bolt 3 is provided with a box mounting hole 51 for external tools to remove the studded hexagon socket bolt 3.

[0023] When installing the locking body 1, one end of the locking body 1 facing the operation hole 11 is installed on the display module 4 or the installation box 5, and the other end is arranged facing the installation box 5 or the display module 4. The user can use a tool (such as a hexagonal wrench) to pass through the module installation hole 41 and the box installation hole 51 to tighten or remove the stud hexagon socket bolt 3 to achieve installation and removal of the display module 4.

[0024] For example, a hex key is inserted into the locking member body 1 through the operation hole 11 and inserted into the double-headed hexagon socket head bolt 3 to drive its rotation, so that the double-headed hexagon socket head bolt 3 is locked. Conversely, a tool can be used to rotate it in the reverse direction for quick disassembly. Moreover, both ends of the double-headed hexagon socket head bolt 3 are provided with hexagon socket holes. Therefore, in addition to operating the bolt with a tool through the operation hole 11, the end far from the operation hole 11 can also use a tool to pass through the display module 4 or the mounting box 5 and unlock the bolt. Thus, the front and back sides of the display module 4 can be disassembled and assembled. Through the above structure, not only can the display module 4 be disassembled and assembled on both its front and back sides, but also the display module 4 and the display screen box body locked by this locking structure have the advantages of high installation strength, high precision, strong weather resistance, and quick disassembly and assembly.

[0025] Referring to Figures 1 to 3 , in an embodiment of the present application, the surface of the locking member body 1 facing the operation hole 11 is connected to the display module 4, and the surface of the locking member body 1 facing the limiting structure is connected to the mounting box 5. Considering that when using a hex key to rotate the double-headed hexagon socket head bolt 3, the situation of the operator slipping during operation may occur. To avoid scratching the display module when slipping during operation, preferably, the side of the double-headed hexagon socket head bolt 3 facing the display module 4 is provided with an operation hole 11 with a certain depth, so that the operator will not slip during operation on this side.

[0026] Referring to Figures 2 to 3 , in an embodiment of the present application, a circular ring column 13 protrudes along the edge of the operation hole 11 of the locking member body 1, and the circular ring column 13 passes through the module mounting hole 41.

[0027] In a locking structure for enabling the front and back sides of the display module 4 to be disassembled and assembled in the present application, by passing the circular ring column 13 through the module mounting hole 41 of the display module 4, users can use a tool to pass through the operation hole 11 and disassemble or install the double-headed hexagon socket head bolt 3 when the display module 4 is not disassembled, which can improve the disassembly and assembly efficiency.

[0028] Referring to Figures 1 to 3 , in an embodiment of the present application, the limiting structure is a cover plate 2. A cover plate through hole 21 is opened at the position of the cover plate 2 opposite to the double-headed hexagon socket head bolt 3. The cover plate through hole 21 is coaxially arranged and communicated with the countersunk head cavity 12, and the cover plate 2 is threadedly connected to the locking member body 1.

[0029] In a locking structure that enables the front and back of the display module 4 to be disassembled and assembled, the cover plate 2 is fixed to the locking member body 1 by bolts. The detachable structure facilitates the maintenance of the double-headed hexagon socket bolt 3. The diameter of the through hole 21 of the cover plate is smaller than the diameter of the annular platform 32 of the double-headed hexagon socket bolt 3, which can prevent the double-headed hexagon socket bolt 3 from coming out of the countersunk head cavity 12 and plays a limiting role. With this structure, the locking member can be easily disassembled, improving the maintenance efficiency.

[0030] Referring to Figures 2 to 3 , in an embodiment of the present application, the double-headed hexagon socket bolt 3 sequentially includes an integrally formed annular platform 32, a connecting portion 31, and a threaded section 33. The annular platform 32 is located within the countersunk head cavity 12. The annular platform 32 and the connecting portion 31 are coaxially arranged. The diameter of the connecting portion 31 is less than or equal to the diameter of the through hole 21 of the cover plate, and the height of the connecting portion 31 is equal to the height of the cover plate 2.

[0031] The annular platform 32 and the threaded section 33 are relatively provided with hexagon socket holes, and a connecting portion 31 is provided between them. The connecting portion 31 is a smooth cylinder, and the height of the connecting portion 31 is equal to the height of the cover plate 2. When the double-headed hexagon socket bolt 3 passes through the cover plate 2 through the connecting portion 31, the threaded section 33 will not affect the cover plate 2 itself. The connecting portion 31 can protect the cover plate 2 as a transition and enable the double-headed hexagon socket bolt 3 to rotate freely, avoiding damage to the cover plate 2 caused by the threads of the threaded section 33, and improving the service life of the cover plate 2 and the double-headed hexagon socket bolt 3.

[0032] In the drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components; in the description of the present application, it should be understood that if there are terms such as "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
