Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display screen assembly structure. Background Technology

[0002] The display combination structure is a bracket structure that can be fixed by a single support base and cantilevered to extend two independent arms. It allows users to install two monitors side by side and flexibly adjust their respective positions and viewing angles.

[0003] The existing display panel assembly structure results in disorganized storage of tightening tools, which can easily lead to their loss. Furthermore, the existing display panel assembly structure has a small contact surface between the tightening tools and the interface, making them prone to slipping when force is applied, which is inconvenient to use and poses operational safety hazards.

[0004] Existing display panel assembly structures typically lack dedicated storage locations for installation tools. Tools are left lying around after use and are easily lost. When adjustments or disassemblies are needed, suitable tools are often hard to find. The shallow screw interfaces in existing structures result in a small contact area for tightening tools when force is applied, making them prone to slipping. This not only causes operational difficulties but also poses safety hazards. If a tightening tool slips while applying force, the user's hand is likely to hit the metal parts. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] like Figure 1 - Figure 10As shown, this utility model provides a technical solution: a display screen assembly structure, including a clamping and fixing structure 1, a lower support arm 2 is provided on the top of the clamping and fixing structure 1, an upper support arm 3 is provided on the top of the lower support arm 2, a universal rotating head 4 is fixedly connected to the end of the upper support arm 3 away from the lower support arm 2, the clamping and fixing structure 1 includes a C-shaped clamp 11, a fixing groove 12 is fixedly connected to the top of the C-shaped clamp 11, the fixing groove 12 includes a housing 121, an interface 122 is fixedly connected to the outer side of the housing 121, a screw 123 is provided on the inner side of the interface 122, and the screw 123 and the housing 121 are engaged and connected.

[0037] The upper support arm 3 includes a second connecting arm 31. A rotating arm 35 is fixedly connected to one end of the outer side of the second connecting arm 31. A connecting rod 36 is fixedly connected to one end of the rotating arm 35 away from the second connecting arm 31. A support fixing structure 32 is rotatably connected to the outer side of the connecting rod 36. A wire harness structure 33 is fixedly connected to one side of the second connecting arm 31. A storage structure 34 is fixedly connected to the side of the second connecting arm 31 adjacent to the wire harness structure 33. The support fixing structure 32 includes a support outer frame 321. An interface 322 is fixedly connected to one side of the support outer frame 321. A screw 323 is provided on the inner side of the interface 322. The screw 323 is engaged with the support outer frame 321.

[0038] The storage structure 34 includes a flip panel 341, a storage box 342 at the bottom of the flip panel 341, a quick-release structure 343 on one side of the flip panel 341, a rotating rod 346 fixedly connected to one side of the storage box 342, a rotating ring 344 rotatably connected to one end of the rotating rod 346, the outer side of the rotating ring 344 fixedly connected to the end of the flip panel 341 away from the quick-release structure 343, and a rotating ring 345 rotatably connected to the outer side of the rotating rod 346 away from the rotating ring 344, the outer side of the rotating ring 345 fixedly connected to the end of the rotating rod 346 away from the rotating ring 344. 5. The end away from the quick-release structure 343 is rotatably connected. The quick-release structure 343 includes a rotating rod 3431. A flip plate 3432 is fixedly connected to the outer side of the rotating rod 3431. Both ends of the rotating rod 3431 are rotatably connected to the flip plate 341. A buckle 3433 is fixedly connected to one side of the flip plate 3432. The quick-release structure 343 also includes a telescopic ball 3434. A fixing block 3435 is fixedly connected to the end of the telescopic ball 3434 with a spring. The outer side of the fixing block 3435 is fixedly connected to the side of the storage box 342 near the quick-release structure 343.

[0039] In this embodiment, the rotation of the rotating ring 344, which is rotatably connected to the rotating rod 346, causes the rotating plate 341, which is fixedly connected to the rotating ring 344, to rotate. The rotation of the rotating ring 345, which is rotatably connected to the rotating rod 346, causes the storage box 342, which is rotatably connected to the rotating ring 345, to rotate, thereby achieving the purpose of adjusting the angle between the rotating plate 341 and the storage box 342. Similarly, the rotation of the rotating rod 3431 causes the rotating plate 3432, which is fixedly connected to the rotating rod 3431, to rotate, thereby achieving the purpose of adjusting the angle between the rotating plate 3432 and the rotating plate 341. When the rotating plate 3432 and the rotating plate 341 rotate... When the angle is 90 degrees, the buckle 3433, which is fixedly connected to the flip plate 3432, squeezes the telescopic ball 3434, further compressing the spring end of the telescopic ball 3434 until the protrusion at the front end of the buckle 3433 completely exceeds the telescopic ball 3434. At this point, the spring end of the telescopic ball 3434 springs back, thus achieving the purpose of locking. The angle between the flip plate 3432 and the storage box 342 is adjusted again, so that the buckle 3433, which is fixedly connected to the flip plate 3432, squeezes the telescopic ball 3434 again until the protrusion at the front end of the buckle 3433 completely disengages from the telescopic ball 3434. At this point, the spring end of the telescopic ball 3434 springs back, thus achieving the purpose of quick release. This facilitates the storage of tightening tools and prevents them from being lost.

[0040] By rotating the connecting rod 36, the rotating arm 35, which is fixedly connected to the connecting rod 36, rotates, which in turn rotates the connecting arm 31, which is fixedly connected to the rotating arm 35, and then rotates the universal head 4, which is fixedly connected to the connecting arm 31, thereby achieving the purpose of adjusting the height of the display screen. The upper support arm 3, which is fixedly connected to the connecting arm 31, is made of elastic plastic and can fix the wires.

[0041] The C-shaped clamp 11 is used to clamp the tabletop, thus fixing the clamping and fixing structure 1, which is fixedly connected to the C-shaped clamp 11, onto the tabletop. The support rod 24 is then snapped into the fixing groove 12. By rotating the screw 123, the support rod 24 is pressed down. The inner side of the outer shell 121 is provided with a gasket, which can be adjusted by rotating the screw 123 to change the contact surface and pressure between the gasket and the support rod 24, thereby changing the friction and ultimately adjusting the tightness of the screw 123 to achieve the purpose of load-bearing of the support arm. In this embodiment, the fixing groove 12, fixing groove 22, support fixing structure 32, connecting structure 46, and connecting block 42 are all provided with gaskets, which can be adjusted by changing the tightness of the screws 123, 323, 363, and 49 to change the friction and ultimately adjust the load-bearing of the support arm.

[0042] Because the contact area between the tightening tool and screw 123 is small and prone to slippage, making operation difficult, the contact area for applying force to the tightening tool can be increased by setting interface 122. At the same time, the top of the tightening tool is fixed within a certain range to prevent slippage and achieve the purpose of making operation more convenient. In this embodiment, interfaces 122, 322, 43, and 362 can all achieve the purpose of preventing slippage and making operation more convenient. The principle is to increase the contact area for applying force to the tightening tool and fix the top of the tightening tool to achieve the purpose of making operation more convenient.

[0043] Example 2

[0044] like Figure 1 - Figure 12 As shown, the lower support arm 2 includes a connecting arm 21. One end of the connecting arm 21 is fixedly connected to a support rod 24. The end of the connecting arm 21 away from the support rod 24 is fixedly connected to a fixing groove 22. The structure of the fixing groove 22 is the same as that of the fixing groove 12. A wire harness structure 23 is fixedly connected to the outside of the connecting arm 21.

[0045] The universal rotating head 4 includes a display screen fixing plate 41. A connecting block 42 is fixedly connected to one side of the display screen fixing plate 41. An interface 43 is fixedly connected to the top of the connecting block 42. A screw 49 is provided on the inner side of the interface 43. The screw 49 and the connecting block 42 are engaged. A connecting rod 44 is rotatably connected to the side of the connecting block 42 away from the display screen fixing plate 41. A fixing block 45 is fixedly connected to the end of the connecting rod 44 away from the connecting block 42. A connecting rod 451 is fixedly connected to the fixing block 45. A connecting structure 46 is provided on the outer side of the connecting rod 451.

[0046] The connecting structure 46 includes a connecting block 3 461, an interface 4 362 fixedly connected to one side of the connecting block 3 461, a screw 3 363 provided on the inner side of the interface 4 362, the screw 3 363 and the connecting block 3 461 engaging, a connecting rod 3 451 and the connecting block 3 461 rotatably connected, a connecting block 47 fixedly connected to the side of the connecting block 3 461 away from the fixed block 2 45, and a rotating rod 3 48 rotatably connected to the connecting block 4 47.

[0047] In this embodiment, the connecting block 47, which is rotatably connected to the rotating rod 3 48, rotates up and down, thereby causing the connecting structure 46, which is fixedly connected to the connecting block 47, to rotate up and down. This causes the connecting rod 2 44, which is fixedly connected to the connecting structure 46, to rotate up and down. This further causes the connecting block 1 42, which is rotatably connected to the connecting rod 2 44, to rotate up and down, and then causes the display screen fixing piece 41, which is fixedly connected to the connecting block 1 42, to rotate up and down. Finally, the fixing block 2 45 rotates left and right, thereby causing the connecting rod 2 44, which is fixedly connected to the fixing block 2 45, to rotate left and right. This further causes the connecting block 1 42, which is rotatably connected to the connecting rod 2 44, to rotate left and right, and finally causes the display screen fixing piece 41, which is fixedly connected to the connecting block 1 42, to rotate left and right. Through the above-mentioned up-and-down and left-and-right rotations, the display screen fixing piece 41 can be adjusted to more angles, so that the display screen after being fixed to the display screen fixing piece 41 can be adjusted to different angles.

[0048] Working principle:

[0049] like Figure 1 - Figure 12 As shown, by rotating the rotating ring 344, which is rotatably connected to the rotating rod 346, the rotating ring 344 rotates, thereby causing the flip plate 341, which is fixedly connected to the rotating ring 344, to rotate. Furthermore, by rotating the rotating ring 345, which is rotatably connected to the rotating rod 346, the rotating ring 345 rotates, thereby causing the storage box 342, which is rotatably connected to the rotating ring 345, to rotate. This achieves the purpose of adjusting the angle between the flip plate 341 and the storage box 342. Similarly, by rotating the rotating rod 3431, the rotating plate 3432, which is fixedly connected to the rotating rod 3431, rotates, thereby achieving the purpose of adjusting the angle between the flip plate 3432 and the flip plate 341. When the flip plate 3432 and... When the flip plate 341 is at a 90-degree angle, the buckle 3433, which is fixedly connected to the flip plate 3432, squeezes the telescopic ball 3434, further compressing the spring end of the telescopic ball 3434 until the protrusion at the front end of the buckle 3433 completely exceeds the telescopic ball 3434. At this point, the spring end of the telescopic ball 3434 springs back, thus achieving the purpose of locking. The angle between the flip plate 3432 and the storage box 342 is adjusted again, so that the buckle 3433, which is fixedly connected to the flip plate 3432, squeezes the telescopic ball 3434 again until the protrusion at the front end of the buckle 3433 completely disengages from the telescopic ball 3434. At this point, the spring end of the telescopic ball 3434 springs back, thus achieving the purpose of quick release.

[0050] By rotating the connecting rod 36, the rotating arm 35, which is fixedly connected to the connecting rod 36, rotates, which in turn rotates the connecting arm 31, which is fixedly connected to the rotating arm 35, and then rotates the universal head 4, which is fixedly connected to the connecting arm 31, thereby achieving the purpose of adjusting the height of the display screen. The upper support arm 3, which is fixedly connected to the connecting arm 31, is made of elastic plastic and can fix the wires.

[0051] By rotating the connecting block 47, which is rotatably connected to the rotating rod 3 48, up and down, the connecting structure 46, which is fixedly connected to the connecting block 47, rotates up and down, and the connecting rod 2 44, which is fixedly connected to the connecting structure 46, rotates up and down, and the connecting block 1 42, which is rotatably connected to the connecting rod 2 44, rotates up and down, and the display screen fixing piece 41, which is fixedly connected to the connecting block 1 42, rotates up and down. Then, by rotating the fixing block 2 45, the connecting rod 2 44, which is fixedly connected to the fixing block 2 45, rotates left and right, and the connecting block 1 42, which is rotatably connected to the connecting rod 2 44, rotates left and right, and the display screen fixing piece 41, which is fixedly connected to the connecting block 1 42, rotates left and right. Through the above up and down rotation and left and right rotation, the display screen fixing piece 41 can be adjusted to more angles. The purpose is to make the display screen after being fixed to the display screen fixing piece 41 adjustable to different angles.

[0052] The C-shaped clamp 11 is used to clamp the tabletop, thus fixing the clamping and fixing structure 1, which is fixedly connected to the C-shaped clamp 11, onto the tabletop. The support rod 24 is then snapped into the fixing groove 12. By rotating the screw 123, the support rod 24 is pressed down. The inner side of the outer shell 121 is provided with a gasket, which can be adjusted by rotating the screw 123 to change the contact surface and pressure between the gasket and the support rod 24, thereby changing the friction and ultimately adjusting the tightness of the screw 123 to achieve the purpose of load-bearing of the support arm. In this embodiment, the fixing groove 12, fixing groove 22, support fixing structure 32, connecting structure 46, and connecting block 42 are all provided with gaskets, which can be adjusted by changing the tightness of the screws 123, 323, 363, and 49 to change the friction and ultimately adjust the load-bearing of the support arm.

[0053] Because the contact area between the tightening tool and screw 123 is small and prone to slippage, making operation difficult, the contact area for applying force to the tightening tool can be increased by setting interface 122. At the same time, the top of the tightening tool is fixed within a certain range to prevent slippage and achieve the purpose of making operation more convenient. In this embodiment, interfaces 122, 322, 43, and 362 can all achieve the purpose of preventing slippage and making operation more convenient. The principle is to increase the contact area for applying force to the tightening tool and fix the top of the tightening tool to achieve the purpose of making operation more convenient.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
