Description

Technical Field

[0001] This utility model belongs to the field of monitor stand technology, specifically a quick-release structure for a monitor base. Background Technology

[0002] A monitor stand is a support device used to fix and adjust the position of a monitor. It usually consists of a base, a column, and a connecting arm. Its core function is to meet the ergonomic needs of users for screen viewing angle through multi-directional adjustments (such as height adjustment, horizontal rotation, forward and backward tilting, and vertical flipping), effectively relieving neck fatigue caused by prolonged computer use. To ensure stability, the main body of the stand is generally made of high-strength metal materials (such as aluminum alloy or carbon steel), which combines load-bearing capacity and durability.

[0003] However, existing monitor stands generally adopt a design where the base and the column are molded as a single piece, which is processed directly into a whole component using a single mold. This one-piece molding process is relatively complex, resulting in high production costs. Secondly, since the base and the column cannot be separated, if either the base or the column is damaged, both the base and the column must be replaced together, resulting in high maintenance costs for users. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release structure for a monitor stand to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-release structure for a monitor stand includes a column, a base body, and a locking screw. The column contains a lifting seat and a connecting seat. One side of the column has a movable hole, and the lifting seat has a mounting seat extending out of the movable hole on one side. The mounting seat is used to mount a monitor. The connecting seat includes a bottom component and a connector. The bottom component is inserted into the base body. The bottom of the base body has an upward protrusion. The upward protrusion, the bottom component, and the connector have a communicating through hole. An internally threaded sleeve is provided within the through hole of the connector. The locking screw passes sequentially through the through hole of the upward protrusion and the bottom component, and is threadedly connected to the internally threaded sleeve of the connector, with its head embedded inside the upward protrusion. The head of the locking screw is rotatably connected to a handle. The upward protrusion, located on the outer periphery of the through hole, has several protrusions for raising the handle.

[0007] Furthermore, the lifting seat includes a fixing component and a connecting component two. A constant force spring is installed inside the connecting component two. The coiled end of the constant force spring is rotatably disposed inside the connecting component two. The fixing component is provided with an insertion block. The fixing end of the constant force spring is provided with an insertion hole for inserting the insertion block. The mounting seat is installed on one side of the connecting component two.

[0008] Furthermore, the lifting seat includes a fixing component and a connecting component two. A spiral spring is installed inside the connecting component two. The coiled end of the spiral spring is rotatably disposed inside the connecting component two. The fixing component is provided with an insertion block. The fixing end of the spiral spring is provided with an insertion hole two for inserting the insertion block. The mounting seat is installed on one side of the connecting component two.

[0009] Furthermore, a rotating shaft is rotatably connected to the center of the winding end of the spiral spring. Both ends of the rotating shaft extend to the outside of the spiral spring, and two limiting members are spaced apart on each side. The space between the two limiting members on each side forms a rope groove. A rotating shaft is rotatably connected inside the connecting member. The axes of the rotating shaft and the rotating shaft are parallel. Both ends of the rotating shaft are spaced apart, and the space between the two limiting members on each side forms a rope groove. The positions of the rope groove and the rope groove on each side correspond and are connected by a pull rope. The winding end of the pull rope is fixed to the rope groove. Both ends of the rotating shaft extend to the outside through the connecting member and the column. One end is threadedly connected to a limiting sleeve, and the other end is provided with a control component for controlling the rotation of the rotating shaft.

[0010] Furthermore, the control component includes a ratchet I disposed at one end of the rotating shaft II and a bracket fixedly connected to the column. One side of the ratchet I is provided with a ratchet II that meshes with it, and the other side of the ratchet II is provided with a cross connector. The bracket is rotatably connected to a rotating shaft III on the side away from the column. The two ends of the rotating shaft III are respectively provided with a rotating wheel and a mounting sleeve. The rotating wheel is located outside the bracket, and the mounting sleeve is located inside the bracket. A cross groove is provided at the end of the mounting sleeve facing the ratchet II. The cross connector is inserted into the cross groove, and a certain amount of space is left between the bottom of the cross groove and the top of the cross connector.

[0011] Furthermore, the cross connector is fitted with a return spring, one end of which abuts against the ratchet wheel and the other end against the mounting sleeve.

[0012] Furthermore, the outer wall of the mounting sleeve is provided with a plurality of fixing holes evenly arranged along the circumferential direction, and a pin is inserted into the upper end of the bracket, with the bottom of the pin inserted into the fixing hole.

[0013] The beneficial effects of this utility model are:

[0014] This utility model features an upper protrusion at the bottom of the base body, with a through hole connecting the upper protrusion, the bottom component, and the first connector. An internally threaded sleeve is installed inside the through hole of the first connector. Locking screws pass through the through holes of the upper protrusion and the bottom component in sequence and are threadedly connected to the internally threaded sleeve of the first connector, thereby achieving a detachable connection between the base body and the column. This structure allows the column and the base to be processed independently without the need for integral molding, reducing manufacturing costs and improving production efficiency. At the same time, when the base or column is damaged, only the corresponding parts need to be replaced, avoiding the need for complete replacement and saving maintenance costs.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please refer to Figure 1-12 ;

[0031] A quick-release structure for a monitor stand includes a column 1, a base body 2, and locking screws 3. The column 1 contains a lifting seat 4 and a connecting seat 5. The lifting seat 4 is located at the top of the column 1, and the connecting seat 5 is located at the bottom of the column 1. A movable hole 6 is provided on one side of the column 1, and a mounting seat 7 extending out of the movable hole 6 is installed on one side of the lifting seat 4. The mounting seat 7 is used to mount the monitor. By controlling the lifting seat 4 to move up and down along the movable hole 6, the height of the monitor in the vertical direction can be adjusted. The connecting seat 5 includes a bottom component 8 and a connector 9. The bottom component 8 is inserted into the base body 2, and the bottom of the base body 2 has an upward protrusion. 21. The upper protrusion 21, the bottom component 8, and the connector 9 are provided with a through hole 22. The through hole 22 of the connector 9 is provided with an internal threaded sleeve 24. The locking screw 3 passes through the through hole 22 of the upper protrusion 21 and the bottom component 8 in sequence and is threadedly connected to the internal threaded sleeve 24 of the connector 9, thereby realizing the detachable connection between the base body 2 and the column 1. This structure allows the column 1 and the base to be processed independently without the need for integral molding, which reduces manufacturing costs and improves production efficiency. At the same time, when the base or the column 1 is damaged, only the corresponding parts need to be replaced, avoiding the need for overall replacement and saving maintenance costs. After the locking screw 3 is tightened, its head is embedded in the upper protrusion 21 and does not protrude from the bottom surface of the base body 2, ensuring that the bottom surface is flat and does not affect the stability of placement. The head of the locking screw 3 is rotatably connected to the handle 31, which makes it easy for the user to manually tighten or loosen the screw. The disassembly and assembly operations can be completed without the aid of additional tools. The upper protrusion 21 is provided with several protrusions 23 on the outer periphery of the through hole 22 to raise the handle 31, preventing the handle 31 from being completely attached to the upper protrusion 21 and making it difficult to grip.

[0032] Implementation Method 1: The lifting seat 4 includes a fixing member 41 and a connecting member 2 42. A constant force spring 43 is installed inside the connecting member 2 42. The coiled end of the constant force spring 43 is rotatably disposed inside the connecting member 2 42. The fixing member 41 is provided with a plug 411. The fixed end of the constant force spring 43 is provided with a first insertion hole 431 for inserting the plug 411 to realize the positioning and connection of the fixed end. The mounting seat 7 is installed on one side of the connecting member 2 42. The constant force spring 43 tends to force the connecting member 1 9 to move upward. The elastic force generated by the constant force spring 43 is exactly balanced with the total weight of the connecting member 1 9, the mounting seat 7 and the display as a whole, thereby providing a supporting force for supporting the connecting member 1 9 and realizing the height adjustment of the display.

[0033] Implementation Method 2: The lifting seat 4 includes a fixing member 41 and a connecting member 2 42. A spiral spring 44 is installed inside the connecting member 2 42. The coiled end of the spiral spring 44 is rotatably disposed inside the connecting member 2 42. The fixing member 41 is provided with a plug 411. The fixed end of the spiral spring 44 is provided with a second insertion hole 441 for inserting the plug 411 to achieve positioning and connection of the fixed end. The mounting seat 7 is installed on one side of the connecting member 2 42. It should be noted that the elastic force of the spiral spring 44 in this design is greater than the sum of the weight of the connecting member 1 9, the mounting seat 7 and the display as a whole. Therefore, the spiral spring 44 always has an upward contraction tendency, thereby forcing the connecting member 2 42 to move automatically upward. In this way, the connecting member 2 42 can automatically rise under the action of the spiral spring 44 without the need for manual lifting by the user, which improves the convenience of operation and user experience.

[0034] Additionally, a rotating shaft 45 is rotatably connected to the center of the winding end of the spiral spring 44. Both ends of the rotating shaft 45 extend to the outside of the spiral spring 44, and two limiting members 46 are spaced apart on each side. The space between the two limiting members 46 on each side forms a rope groove 47. A rotating shaft 91 is rotatably connected inside the connecting member 9. The axes of the rotating shaft 45 and the rotating shaft 91 are parallel. Both ends of the rotating shaft 91 are spaced apart, and the space between the two limiting members 92 on each side forms a rope groove 93. The positions of the rope groove 47 and the rope groove 93 on each side correspond and are connected by a pull rope 94. The winding end of the pull rope 94 is fixed on the rope groove 93, and the fixed end is fixed on the rope groove 47. The rotating shaft 94... Both ends of 91 extend to the outside through connector 9 and column 1. One end is threaded to a limit sleeve 95, and the other end is equipped with a control component 96 to control the rotation of the second rotating shaft 91. The limit sleeve 95 and the control component 96 cooperate to prevent the second rotating shaft 91 from falling off axially. The control component 96 controls the rotation of the second rotating shaft 91. When the user operates the control component 96 to drive the second rotating shaft 91 to rotate clockwise, the second rotating shaft 91 gradually winds the pull rope 94 into the rope groove 93, thereby pulling the first rotating shaft 45 to move downward. At this time, the spiral spring 44 is gradually stretched and unfolded, thereby driving the second connector 42 to move downward, realizing the overall lowering adjustment of the display. The synchronous rotation of the two pull ropes 94 achieves the balanced lifting and lowering of the display.

[0035] Specifically, the control component 96 includes a ratchet 961 disposed at one end of the rotating shaft 91 and a bracket 962 fixedly connected to the column 1. A ratchet 963 is provided on one side of the ratchet 961 and engages therewith. A cross connector 9631 is provided on the other side of the ratchet 963. A rotating shaft 9621 is rotatably connected to the side of the bracket 962 away from the column 1. A rotating wheel 9622 and a mounting sleeve 9623 are respectively provided at both ends of the rotating shaft 9621. The rotating wheel 9622 is located outside the bracket 962, making it easy for the user to hold and apply force to rotate. The mounting sleeve 9623 is located inside the bracket 962 and has a cross groove 9624 at its end facing the ratchet 963. The cross connector 9631 is inserted into the cross groove 9624 to fix the position of the ratchet 963 and to realize the transmission of rotational motion. When the rotating wheel 9622 is rotated clockwise, the rotating shaft 9621 drives the mounting sleeve 9623 to rotate synchronously. The cross groove 9624 on the mounting sleeve 9623 drives the ratchet 963 to rotate. Since the ratchet 963 is engaged with the ratchet 961, the ratchet 963 drives the ratchet 961 to rotate clockwise synchronously, which in turn drives the rotating shaft 91 to rotate together. When the rotating shaft 91 rotates, it winds up the pull rope 94, pulling the rotating shaft 45 downward, causing the spiral spring 44 to gradually unfold, thereby driving the connecting piece 42 to move downward, and finally realizing the downward adjustment of the display. The whole process does not require manual pressing of the display, avoiding the problem of the display deflecting downward when pressing the display to lower it. There is a certain amount of space between the bottom of the cross slide 9624 and the top of the cross connector 9631, allowing the ratchet 2 963 to move. If it is necessary to raise the height of the monitor, simply rotate the rotating wheel 9622 counterclockwise. At this time, under the action of the inclined surface of the ratchet 1 961, the ratchet 2 963 will move towards the mounting sleeve 9623, and the ratchet 2 963 and the ratchet 1 961 will disengage, thus not hindering the rotation of the ratchet 1 961. Therefore, the spiral spring 44 returns to its contracted state, automatically pushing the connector 2 42 upward, causing the monitor to rise. When the monitor is raised to the appropriate height, the ratchet 2 963 and the ratchet 1 961 are re-engaged to lock the monitor at the current height position.

[0036] In this embodiment, the cross connector 9631 is fitted with a return spring 964. One end of the return spring 964 abuts against ratchet 2 963, and the other end abuts against the mounting sleeve 9623. By installing the return spring 964, when the monitor needs to be raised, the user only needs to rotate the rotating wheel 9622 counterclockwise, causing ratchet 2 963 to slide out along the inclined surface of ratchet 1 961 and disengage. At this time, ratchet 2 963 will move towards the mounting sleeve 9623, compressing the return spring 964. The compressed return spring 964 will continuously apply a pushing force towards ratchet 1 961 to ratchet 2 963, thereby automatically causing ratchet 2 963 to re-engage with ratchet 1 961 during the monitor's rise. When the monitor is raised to the appropriate position, the user only needs to stop rotating the rotating wheel 9622 to quickly lock the monitor position without manually pushing ratchet 2 963 to engage with ratchet 1 961, thus improving the user experience.

[0037] In this embodiment, a plurality of fixing holes 9625 are evenly arranged along the circumferential direction on the outer wall of the mounting sleeve 9623. A pin 9626 is inserted into the upper end of the bracket 962, and the bottom of the pin 9626 is inserted into the fixing hole 9625, thereby locking the mounting sleeve 9623 in the current position. This prevents the display from rising on its own when no one is operating it due to the automatic winding action of the spiral spring 44, thus solving the problem that the display cannot be stably fixed at any height.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
