Description

Technical Field

[0001] This utility model relates to the field of production and assembly technology of broadcast control consoles, and in particular to a locking assembly for a flip-type broadcast control console. Background Technology

[0002] A switcher is a specialized device for switching multiple video signals. It selects and switches between different camera feeds from multiple video signals, based on program content and creative needs, to achieve smooth and expressive program production. With the development of lightweight and miniaturized switcher design, integrated switchers have emerged. For example, a flip-type switcher includes a lower control panel 1, a display cover 2 rotatably connected to the lower control panel 1, several connecting hinge components 13 between the lower control panel 1 and the display cover 2, and a recessed button mounting plate 3 embedded in the lower control panel 1. When the display cover 2 is closed and stored, it needs to be locked onto the lower control panel 1. Currently, existing locking components cannot provide a reliable locking connection. Furthermore, due to the numerous wiring harnesses connected to the switcher, it is necessary to ensure reliable closure of the switcher after storage.

[0003] Therefore, there is an urgent need to propose a locking assembly for a flip-type broadcast console that is simple in structure and reliable in opening and closing operations. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a locking assembly for a flip-type broadcast control console. The technical solution adopted by this utility model is as follows:

[0005] A locking assembly for a flip-type broadcast control console, the flip-type broadcast control console including a lower operating table, a display screen cover rotatably connected to the lower operating table, and a plurality of connecting hinge assemblies disposed between the lower operating table and the display screen cover. The locking assembly of the flip-type broadcast control console includes a lower connecting hole opened on the lower operating table, a lower locking assembly disposed on the lower operating table and placed in the lower connecting hole, and an upper locking assembly disposed on the display screen cover and arranged opposite to the lower locking assembly.

[0006] A first latch mounting hole assembly is provided on the display cover plate; a second latch mounting hole assembly is provided on the lower operating platform; the first latch mounting hole assembly and the second latch mounting hole assembly have the same structure; the second latch mounting hole assembly is located below the lower connecting hole; the first latch mounting hole assembly includes a spring mounting groove and a transverse groove that are opened on the display cover plate and communicate with each other, several locking hook through holes that are opened on the inner side of the display cover plate and communicate with the transverse groove, and a first strip-shaped stepped hole that is opened on the top of the display cover plate and communicates with the transverse groove; a spring connecting post is provided in the spring mounting groove;

[0028] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0029] like Figures 1 to 8 As shown, this embodiment provides a flip-type broadcast control console, which includes a lower operating platform 1, a display screen cover 2 rotatably connected to the lower operating platform 1, several connecting hinge assemblies 13 disposed between the lower operating platform 1 and the display screen cover 2, a recessed button mounting plate 3 embedded in the lower operating platform 1, several operation buttons disposed on the recessed button mounting plate 3, a circuit board assembly disposed in the lower operating platform 1 and connected to the operation buttons, a lower connecting hole 6 opened on the lower operating platform 1, a lower locking assembly 5 disposed on the lower operating platform 1 and placed in the lower connecting hole 6, an upper locking assembly 4 disposed on the display screen cover 2 and arranged opposite to the lower locking assembly 5, and a power module 7 disposed in the lower operating platform 1 and electrically connected to the operation buttons and the circuit board assembly. A rubber pad 13 is provided at each of the four top corners of the lower operating platform 1. It should be noted that the operation buttons, circuit board assembly, and power module 7 of this embodiment are existing products and will not be described in detail here.

[0030] In this embodiment, to achieve miniaturization and easy storage, a flip-up lower operating platform 1 and a display screen cover 2 are adopted, and a recessed button mounting plate 3 is configured. The recessed button mounting plate 3 includes a connecting upper edge 31 connected to the lower operating platform 1, a button support plate 32 disposed at the lower part of the connecting upper edge 31, button mounting holes 33, strip-shaped stepped holes 34, and remote control mounting tapered holes 35 opened on the button support plate 32, and a circular hole 36 opened in the remote control mounting tapered hole 35.

[0031] In this embodiment, to achieve a reliable locking connection, a first locking mounting hole assembly is provided on the display cover plate 2, and a second locking mounting hole assembly is provided on the lower operating platform 1. The first and second locking mounting hole assemblies have the same structure. Taking the first locking mounting hole assembly as an example, it includes a spring mounting groove 21 and a transverse groove 22 that are formed on the display cover plate 2 and are interconnected; several hook through holes 23 that are formed on the inner side of the display cover plate 2 and communicate with the transverse groove 22; and a first strip-shaped stepped hole 25 that is formed on the top of the display cover plate 2 and communicates with the transverse groove 22. A spring connecting post 24 is provided in the spring mounting groove 21. Here, the second locking mounting hole assembly is located below the lower connecting hole 6.

[0032] In addition, the structure of the lower locking assembly 5 is the same as that of the upper locking assembly 4. Taking the upper locking assembly 4 as an example, it includes a linkage bar 42 that is slidably sleeved in the transverse groove 22, a first locking hook 43 that is set at the bottom of the linkage bar 42 and is placed in the locking hook through hole 23, a connecting bar 45 and a sliding block 46 that are fixed on the linkage bar 42 and placed in the first strip-shaped stepped hole 25, a spring connecting hook 44 that is set at one end of the linkage bar 42 and close to the spring mounting groove 21, and a spring 41 that is hung between the spring connecting hook 44 and the spring connecting post 24. When the display cover 2 is closed, the first locking hook 43 inserts into the lower connecting hole 6 and enters the second locking mounting hole assembly, pressing and hanging on the lower locking assembly 5. At this time, the spring 41 is in a stretched state. Alternatively, the connecting strip 45 and sliding block 46 on the lower locking assembly 5 and the upper locking assembly 4 can be manually pushed to drive the linkage strip 42 to slide, stretching the spring 41 and using the first locking hook 43 to hook and fasten the lower locking assembly 5 and the upper locking assembly 4. When the display cover 2 is opened, the operator's left hand presses on the sliding block 46 on the lower locking assembly 5 and slides to the left; at the same time, the operator's right hand presses on the sliding block 46 on the upper locking assembly 4 and slides to the right, so that the first locking hook 43 on the lower locking assembly 5 separates from the first locking hook 43 on the upper locking assembly 4, and the springs 41 on both the lower locking assembly 5 and the upper locking assembly 4 are stretched to facilitate reset after disconnection. Here, the lower locking assembly 5 and the upper locking assembly 4 use opposite sliding to disengage, ensuring the reliability of their connection. Furthermore, when the sliding block 46 of the lower locking assembly 5 or the upper locking assembly 4 is erroneously activated—that is, when the sliding block 46 of the lower locking assembly 5 is erroneously activated and moves to the left, or the sliding block 46 of the upper locking assembly 4 is erroneously activated and moves to the right—the first locking hook 43 on the lower locking assembly 5 and the upper locking assembly 4 remains engaged under the pulling action of the spring 41. Therefore, it can be seen that the locking connection can only be released when the sliding blocks 46 of the lower locking assembly 5 and the upper locking assembly 4 move simultaneously in opposite directions, ensuring a reliable connection.

[0033] In this embodiment, to ensure the reliability of the engagement and positioning connection between the lower locking assembly 5 and the upper locking assembly 4, and to reduce the lateral support force on the connecting hinge assembly 13 when the lower locking assembly 5 and the upper locking assembly 4 are disengaged, positioning posts 26 are respectively provided on both sides of the upper part of the display screen cover 2. Simultaneously, positioning holes 12 corresponding to the positioning posts 26 are provided on the lower operating platform 1. Since the lower locking assembly 5 slides to the left and the upper locking assembly 4 slides to the right, they exert a lateral pulling force on the connecting hinge assembly 13. This embodiment uses the positioning posts 26 and positioning holes 12 to provide distributed support, reducing the force on the connecting hinge assembly 13 (i.e., the electrical connection harness) when the lower locking assembly 5 and the upper locking assembly 4 are disengaged, thus extending its service life.

[0034] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
