Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, and in particular to a foldable monitor bracket. Background Technology

[0002] A monitor is a common tool for displaying electronic information in daily life. It is usually mounted on a monitor stand so that users can adjust the height and angle of the monitor to enhance the viewing experience.

[0003] Existing monitor stands require multiple legs or a large base to provide stable support for the monitor, resulting in excessive space and inconvenience for transportation. Therefore, monitor stands are often disassembled into individual parts to reduce transport difficulty, requiring users to assemble them themselves upon receipt, leading to a poor user experience. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a foldable monitor stand, which can reduce transportation difficulties and improve the user experience.

[0005] This utility model provides a foldable monitor stand, comprising: a mounting base with a first limiting portion for mounting a monitor; a first leg rotatably engaged with the mounting base and having a first engaging portion and a second limiting portion arranged opposite each other in the axial direction, the first engaging portion engaging with the first limiting portion to restrict relative rotation between the first leg and the mounting base; a second leg rotatably engaged with the first leg and having a second engaging portion and a third limiting portion arranged opposite each other in the axial direction, the second engaging portion engaging with the second limiting portion to restrict relative rotation between the second leg and the first leg; a third leg rotatably engaged with the second leg and having a third engaging portion engaging with the third limiting portion to restrict relative rotation between the third leg and the second leg; and a connector, one end of which abuts against the third leg, and the other end passing sequentially through the third leg, the second leg, and the first leg and connected to the mounting base, the connector being used to clamp or release the first leg, the second leg, and the third leg with the mounting base.

[0006] The foldable monitor stand provided by this embodiment of the invention has at least the following beneficial effects:

[0007] When needed, the first, second, and third legs can be clamped together using the connector and mounting base, causing the corresponding limiting and mating parts to engage, thus restricting the relative rotation of the first, second, and third legs to support the monitor. When storage is required, the first, second, and third legs can be released using the connector and mounting base, causing the corresponding limiting and mating parts to separate, thereby releasing the restriction on the first, second, and third legs. This allows the first, second, and third legs to rotate relative to each other and fold up, reducing space occupation and simplifying transportation. Thus, the bracket does not need to be disassembled into multiple parts before transportation, meeting transportation requirements, and users do not need to reassemble it upon receipt, improving the user experience.

[0008] In one embodiment of this implementation, one of the first limiting portion and the first mating portion is constructed as two first grooves spaced apart at a certain angle in the circumferential direction, and the other is constructed as two first protrusions, with the two first protrusions extending into the corresponding first grooves respectively; and / or, one of the second limiting portion and the second mating portion is constructed as two second grooves spaced apart at a certain angle in the circumferential direction, and the other is constructed as two second protrusions, with the two second protrusions extending into the corresponding second grooves respectively; and / or, one of the third limiting portion and the third mating portion is constructed as two third grooves spaced apart at a certain angle in the circumferential direction, and the other is constructed as two third protrusions, with the two third protrusions extending into the corresponding third grooves respectively.

[0009] In one embodiment of this implementation, the two first grooves are spaced 180 degrees apart in the circumferential direction and both extend radially, and the widths of the two first grooves are different; and / or, the two second grooves are spaced 180 degrees apart in the circumferential direction and both extend radially, and the widths of the two second grooves are different; and / or, the two third grooves are spaced 180 degrees apart in the circumferential direction and both extend radially, and the widths of the two third grooves are different.

[0011] In one embodiment of this implementation, the first rotating shaft mates with the first shaft hole conical surface; and / or, the second rotating shaft mates with the second shaft hole conical surface; and / or, the third rotating shaft mates with the third shaft hole conical surface.

[0012] In one embodiment of this implementation, the mounting base includes a mounting body and a first fixing plate. The first fixing plate is fixed to the bottom side of the mounting body and forms a relatively protruding first rotating shaft. The first rotating shaft is rotatably engaged with the first support leg.

[0013] In one embodiment of this implementation, the mounting base includes a second fixing plate, which is disposed between the mounting body and the first fixing plate. The side of the second fixing plate facing away from the first fixing plate has a mounting protrusion, and the mounting protrusion has a threaded hole that mates with the connector.

[0041] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 , Figure 1 This is a three-dimensional structural diagram of the foldable display stand 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A schematic diagram of the foldable display stand 100 in its disassembled state; Figure 4 yes Figure 1 A three-dimensional structural diagram of the mounting base 10 in the foldable monitor stand 100; Figure 6 yes Figure 5 A three-dimensional structural diagram of the first leg 20 from another perspective; Figure 8 yes Figure 7 A three-dimensional structural diagram of the second leg 30 from another perspective. This utility model provides a foldable monitor stand 100, which includes a mounting base 10, a first leg 20, a second leg 30, a third leg 40, and a connector 50. The mounting base 10 has a first limiting portion 11 and is used to mount a monitor. The first leg 20 is rotatably engaged with the mounting base 10 and has a first mating portion 21 and a second limiting portion 22 arranged opposite each other in the axial direction. The first mating portion 21 and the first limiting portion 11 are in a concave-convex fit to restrict relative rotation between the first leg 20 and the mounting base 10. The second leg 30 is rotatably engaged with the first leg 20 and has a second mating portion 31 and a third limiting portion 32 arranged opposite each other in the axial direction. The second mating portion 31 and the second limiting portion 22 are in a concave-convex fit to restrict relative rotation between the second leg 30 and the first leg 20. The third leg 40 is rotatably engaged with the second leg 30 and has a third mating portion 41. The third mating part 41 engages with the third limiting part 32 to restrict the relative rotation of the third support leg 40 and the second support leg 30. One end of the connector 50 abuts against the third support leg 40, and the other end passes through the third support leg 40, the second support leg 30, and the first support leg 20 in sequence, and connects to the mounting base 10. The connector 50 is used to clamp or release the first support leg 20, the second support leg 30, and the third support leg 40 with the mounting base 10.

[0042] Specifically, the axes around which the mounting base 10 and the first leg 20 rotate relative to each other, the axes around which the first leg 20 and the second leg 30 rotate relative to each other, and the axes around which the second leg 30 and the third leg 40 rotate relative to each other coincide and are parallel to the vertical direction. That is, the first leg 20, the second leg 30, and the third leg 40 can rotate relative to the mounting base 10 in the horizontal plane. The first leg 20, the second leg 30, and the third leg 40 are used to be mounted on a horizontal support surface such as a tabletop.

[0043] Specifically, the mounting base 10, the first support leg 20, the second support leg 30, and the third support leg 40 are arranged vertically in sequence. The first limiting part 11 is located on the bottom side of the mounting base 10, the first mating part 21 is located on the top side of the first support leg 20, the second limiting part 22 is located on the bottom side of the first support leg 20, the second mating part 31 is located on the top side of the second support leg 30, the third limiting part 32 is located on the bottom side of the second support leg 30, and the third mating part 41 is located on the top side of the third support leg 40. One end of the connecting member 50 abuts against the bottom side of the third support leg 40, and the other end passes through the bottom side of the third support leg 40 and sequentially through the third support leg 40, the second support leg 30, and the first support leg 20 to connect with the mounting base 10. It is understandable that the connector 50 and the mounting base 10 have multiple mounting positions in the axial direction. The tightness of the first leg 20, the second leg 30 and the third leg 40 is different in different mounting positions. The connector 50 can be connected to the mounting base 10 by snap-fit ​​connection, threaded connection or other connection methods.

[0044] Understandably, when the first leg 20, the second leg 30, and the third bracket are clamped, the foldable monitor bracket 100 is in use. The first mating part 21 engages with the first limiting part 11, the second mating part 31 engages with the second limiting part 22, and the third mating part 41 engages with the third limiting part 32 to restrict the relative rotation of the first leg 20, the second leg 30, and the third leg 40, so that the first leg 20, the second leg 30, and the third leg 40 maintain a certain angle in the circumferential direction to better support the monitor. By adjusting the installation position of the connector 50 and the mounting base 10, the first leg 20, the second leg 30, and the third bracket can be released, and the foldable monitor bracket 100 can be stored. The first mating part 21 separates from the first limiting part 11, the second mating part 31 separates from the second limiting part 22, and the third mating part 41 separates from the third limiting part 32, thereby removing the restriction on the first leg 20, the second leg 30, and the third leg 40. The first leg 20, the second leg 30, and the third leg 40 regain their relative rotational freedom, allowing the user to fold them together by rotating the first leg 20, the second leg 30, and the third leg 40, thereby reducing space occupation and facilitating transportation.

[0045] When needed, the first leg 20, the second leg 30, and the third leg 40 can be clamped together using the connector 50 and the mounting base 10, so that the corresponding limiting parts and mating parts are engaged, thereby restricting the relative rotation of the first leg 20, the second leg 30, and the third leg 40 to support the monitor. When storage is required, the first leg 20, the second leg 30, and the third leg 40 can be released using the connector 50 and the mounting base 10, so that the corresponding limiting parts and mating parts are separated, thereby releasing the restriction on the first leg 20, the second leg 30, and the third leg 40, allowing the first leg 20, the second leg 30, and the third leg 40 to rotate relative to each other and fold up, reducing the space occupied and reducing the difficulty of transportation. In this way, the bracket does not need to be disassembled into multiple parts before transportation, which can meet the transportation requirements. Users do not need to reassemble it upon receipt, improving the user experience.
