Description

Technical Field

[0001] This utility model relates to the field of screen bracket technology, specifically a novel computer screen bracket. Background Technology

[0002] A computer monitor stand is a device that allows for flexible adjustment of the monitor's height and angle, designed to improve user experience and comfort. It mainly consists of a support arm, connectors, and a desktop clamp, using a spring or gas spring structure to achieve height adjustment. Using a monitor stand, users can easily adjust the monitor to their most comfortable viewing position, effectively relieving neck and eye fatigue caused by prolonged computer use.

[0003] In addition, monitor stands can save desktop space, making the desktop neater and more organized. They have a small footprint and can be pushed to the edge of the desk or even beyond, making the desktop space more open.

[0004] In summary, computer monitor stands, with their flexible adjustment functions and space-saving features, have become an indispensable piece of equipment in modern office and home life.

[0005] However, the current screen brackets have a complicated overall structure, and most of them use springs or gas springs to achieve the adjustment and lifting functions as well as the positioning and hovering functions.

[0006] Using a spring for positioning and hovering can easily cause the spring to deform under long-term stress, resulting in the bracket being unable to support the screen and losing its function.

[0007] The positioning and hovering function using a gas spring is prone to damage to its airtightness after prolonged use, causing the gas spring to gradually lose its original lifting and support effects. This results in the bracket being unable to maintain the predetermined height or angle after hanging the monitor for a long time, affecting the user experience.

[0008] Therefore, this utility model proposes a novel computer screen stand that is simple in structure and durable to solve the above problems. Utility Model Content

[0062] 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.

[0063] Please see Figure 1-6 A novel computer screen stand includes an upper support arm 1, a lower support arm 4, a base 9 rotatably connected to the lower support arm 4, and a connector 0 for fixing the screen.

[0064] The upper support arm 1 is provided with connecting components 11 at both ends, wherein the upper support arm 1 and the lower support arm 4 are hinged together by the connecting components 11.

[0065] The connecting component 11 includes a connecting base 2 and a hinge component 3;

[0066] The hinge assembly 3 includes a rotating seat 31 hinged to the connecting seat 2, a tensioning member 32, and a first locking member 33 and a second locking member 34 respectively embedded on both sides of the connecting seat 2;

[0067] One end of the rotating seat 31 is fixedly connected to the upper support arm 1, and the other end of the rotating seat 31 is hinged to the connecting seat 2;

[0068] The rotating seat 31 is connected to the connecting seat 2 at one end, and the first protrusion 311 is embedded in the end of the connecting seat 2.

[0069] The first protrusion 311 has connecting tooth surfaces 312 on both sides;

[0070] The first locking member 33 and the second locking member 34 are respectively provided with a first tooth surface 331 and a second tooth surface 341 that are engaged with the connecting tooth surface 312 on their opposite sides;

[0071] The tightening member 32 passes through the first locking member 33 and the first protrusion 311 and is finally disposed in the second locking member 34;

[0072] The end of the tensioning member 32 is provided with a first thread 321, and the second locking member 34 is provided with a second thread 342 that is screwed into the first thread.

[0073] The upper support arm 1 is provided with connecting components 11 at both ends. The upper support arm 1 and the lower support arm 4 are hinged together by the connecting components 11. This structure allows the upper support arm 1 to be adjusted.

[0074] In one embodiment of the present invention, the upper support arm 1 is provided with connecting components 11 at both ends, which are hereinafter referred to as connecting component 11 (upper) and connecting component 11 (lower). One end of the upper support arm 1 is hinged to the lower support arm 4 through the connecting component 11 (lower), and the other end of the upper support arm 1 is hinged to the connector 0 through the connecting component 11 (upper).

[0075] During use, the screen is fixedly connected to the connector 0. One end of the upper support arm 1 is hinged to the connector 0, and the other end of the upper support arm 1 is hinged to the lower support arm 4. The angle between the connector 0 and the upper support arm 1 can be adjusted. When the angle between the connector 0 and the upper support arm 1 is adjusted, the position of the screen changes accordingly (i.e., the orientation of the screen can be adjusted).

[0076] The upper support arm 1 and the lower support arm 4 are hinged together by the connecting component 11. During this process, the connecting component 11 can adjust the included angle between the upper support arm 1 and the lower support arm 4, thereby adjusting the position of the screen (i.e., adjusting the height of the screen while the lower support arm 4 is fixed).

[0077] In one embodiment of the present invention, one end of the tensioning member 32 is provided with a first thread 321, and the other end of the tensioning member 32 is fixedly provided with a tensioning cap for abutting and cooperating with the first locking member 33.

[0078] The connecting component 11 includes two modes: a locking mode (which prevents the hinge part from rotating) and an unlocking mode (which allows the hinge part to continue rotating).

[0079] When the connecting assembly 11 changes from the unlocking mode to the locking mode, the first thread 321 at the end of the tensioning member 32 engages with the second thread 342 in the second locking member 34. During this engagement, the tensioning cap of the tensioning member 32 pushes the first locking member 33 towards the first protrusion 311. In this process, the first thread 321 at the end of the tensioning member 32 engages with the second thread 342, causing the second locking part to move towards the first protrusion 311. This causes the connecting tooth surfaces 312 on both sides of the first protrusion 311 to engage with the first tooth surface 312 of the first locking member 33. The second tooth surface 341 of the second locking member 34 and the second locking member 31 are engaged and fixed. After the tooth surfaces are engaged, the first thread 321 of the tensioning member 32 is screwed to the second thread 342, so that the tensioning cap and the first locking member 33 continue to approach each other until their tooth surfaces are fully engaged. This achieves the fixed connection of the rotating seat 31, the first locking member 33 and the second locking member 34. By adjusting the first protrusion 311 of the tensioning member 32, the first locking member 33 and the second locking member 34 are engaged and disengaged, so that the hinged part no longer rotates, i.e., the locking mode.

[0080] When the connecting assembly 11 is in the process of changing from the locking mode to the unlocking mode, by controlling the first thread 321 at the end of the loosening member 32 to disengage from the second thread 342 in the second locking member 34, the connecting seat 2 or the rotating seat 31 can be slightly shaken to release the engagement of the connecting tooth surface 312, the first tooth surface 331 and the second tooth surface 341, thereby realizing the release of the locking mode.

[0081] This utility model controls the engagement and disengagement of the teeth of the first protrusion 311, the first locking member 33, and the second locking member 34 through the tensioning member 32, thereby controlling the movable hinge and locking of the connecting assembly 11. When the hinge is movable, the screen can be adjusted to rise and fall, and when locked, the screen can be suspended. This utility model controls the suspension of the screen through a mechanical structure. The mechanical structure has high rigidity and stability, can withstand large loads, and can provide stable support. Moreover, this utility model has a simple structure, high stability, and a sturdy and durable mechanical structure.

[0082] In an embodiment of this utility model, a connecting groove 222 is provided on one end of the connecting seat 2 near the first protrusion 311, and the first protrusion 311 is disposed in the connecting groove 222;

[0083] The second locking member 34 includes an engagement layer 343 and a positioning layer 344 arranged sequentially. The positioning layer 344 has a polygonal cross-section, wherein the second tooth surface 341 is provided on the side of the engagement layer 343 away from the positioning layer 344.

[0084] The side wall of the connecting seat 2 is provided with a polygonal positioning groove 201 that is aligned and embedded with the positioning layer 344 and restricts the rotation of the second locking member 34;

[0085] The other side of the connecting seat 2 is provided with a sliding groove 202 that is slidably inserted into the first locking member 33.

[0086] The first protrusion 311 is provided in the connecting groove 222, and the tensioning member 32 passes through the first locking member 33 and the first protrusion 311 and is finally provided in the second locking member 34. During the hinged movement of the connecting assembly 11, the first protrusion 311 of the rotating seat 31 rotates along the axis of the tensioning member 32, thereby realizing the hinged setting of the connecting seat 2 and the rotating seat 31.

[0087] During the screwing process of the first thread 321 of the tensioning member 32 and the second thread 342 of the second locking member 34, the positioning layer 344 of the second locking member 34 and the polygonal positioning groove 201 of the connecting seat 2 are engaged, thereby ensuring that during the adjustment of the tooth surface meshing of the tensioning member 32, the positioning layer 344 and the polygonal positioning groove 201 can prevent the rotation of the second locking member 34 from causing the connecting assembly 11 and the rotating seat 31 to fail to lock.

[0088] During the unlocking process described above, when the first thread 321 of the loosening member 32 and the second thread 342 of the second locking member 34 are unscrewed, the sliding groove 202 enables the first locking member 33 to first disengage the first tooth surface 331 from the connecting tooth surface 312, thereby allowing the first protrusion 311 to have more room to move. When the connecting seat 2 or the rotating seat 31 is slightly shaken, the second tooth surface 341 from the connecting tooth surface 312 can be disengaged more easily.

[0089] In an embodiment of the present invention, the connecting seat 2 includes a first connecting seat 21 for hinged connection of the connecting head 0 and the upper support arm 1 and a second connecting seat 22 for hinged connection of the upper support arm 1 and the lower support arm 4, wherein the hinge assembly 3 is provided in multiple manner and is respectively connected to the first connecting seat 21 and the second connecting seat 22.

[0090] The first connecting seat 21 has a second protrusion 211 at one end away from the upper support arm 1, the second connecting seat 22 has a plug-in part 221 at one end, and the connecting groove 222 is located at the other end of the second connecting seat 22.

[0091] Multiple hinge components 3 are provided and are respectively connected to the first connecting seat 21 and the second connecting seat 22. That is, multiple hinge components 3 are provided and are respectively provided on the first connecting seat 21 and the second connecting seat 22. The first connecting seat 21 is engaged with the hinge component 3 to make the connector 0 hinged to the upper support arm 1. The second connecting seat 22 is engaged with the hinge component 3 to make the upper support arm 1 hinged to the lower support arm. The locking and unlocking instructions have been explained in the above embodiments.

[0092] In an embodiment of this utility model, the connector 0, upper support arm 1, lower support arm 4 and base 9 are arranged sequentially from top to bottom. The plug-in part 221 extends downward from the lower end of the second connector 22. The lower support arm 4 is provided with a plug groove 41 at one end near the upper support arm 1, which is engaged with the plug-in part 221. The plug-in part 221 and the plug groove 41 are rotatably connected.

[0093] The lower support arm 4 has a threaded opening recessed inward on its outer wall. A threaded component 43 is provided in the threaded opening and screwed into it. After the threaded component 43 is screwed into the threaded opening, the end of the threaded component 43 abuts against the side of the insertion part 221 of the first connecting seat 21.

[0094] In one embodiment of this utility model, the plug-in part 221 is cylindrical, and the upper support arm 1 is plugged into and rotated with the plug-in groove 41 through the plug-in part 221, thereby realizing the rotation function and further improving the flexibility of this utility model.

[0095] In one embodiment of this utility model, the upper support arm 1 is hinged to the second connecting seat 22. After the upper support arm 1 is inserted into the insertion slot 41 of the lower support arm 4 through the insertion part 221, it can be screwed into the threaded part 43 through the threaded opening, so that the end of the threaded part 43 abuts against the outer wall of the insertion part 221. Thus, after the upper support arm 1 has adjusted the screen position by rotating through the insertion part 221 and the insertion slot 41, the insertion part 221 can be locked, so that the insertion part 221 and the insertion slot 41 stop rotating. This can better limit the position of the screen and prevent the screen from shifting due to accidental contact.

[0096] In embodiments of this utility model, it further includes a rotation adjustment member 5 for enabling the connector 0 to rotate, a vertical adjustment member 6 for enabling the connector 0 to be vertically adjusted, and a horizontal adjustment member 7 for enabling the connector 0 to be horizontally adjusted.
