Description

Technical Field

[0001] This utility model relates to the field of monitor bracket installation equipment, specifically to a tool-free desktop quick-release clamp for monitor brackets. Background Technology

[0002] Monitor stands have become essential tools in modern office and home environments for supporting monitors, laptops, and other devices. They effectively save desktop space and allow users to flexibly adjust the screen height and viewing angle, meeting ergonomic needs. Currently, many monitor stands are placed directly on the desktop or fixed to a specific position with simple screws. The former suffers from poor stability and is prone to movement or falling due to impacts; the latter requires tools for installation, is cumbersome, and cannot be flexibly adjusted or quickly disassembled on different desktops. For example, a monitor stand disclosed in Chinese Patent 201220278080.3 mainly addresses the adjustment function of the stand itself, but does not address how to install the stand body more quickly, stably, and tool-free on desktops of different thicknesses, and in particular, lacks effective anti-fall and anti-loosening mechanisms.

[0003] Therefore, there is an urgent need in the field for a desktop fixture for monitor stands that is easy to install, requires no tools, clamps securely, and has an anti-loosening function, in order to solve the problems of inconvenient installation, poor stability, and insufficient security in the existing technology.

[0005] According to the technical solution provided by the embodiments of this utility model, a tool-free desktop quick-release clamp for a monitor stand includes a vertical plate. The front side of the vertical plate is provided with a clamping mechanism for clamping and fixing the vertical plate to a desktop. The clamping mechanism includes a bearing plate fixedly connected to the vertical plate, a rotating shaft rotatably disposed on the bearing plate, a gear fixedly installed on the outside of the rotating shaft, a pair of racks meshing with and symmetrically disposed with the gear, a connecting rod fixedly connected between the racks on the left and right sides, a movable clamping plate fixedly connected to the connecting rod, and a fixed clamping plate fixedly connected to the vertical plate. A handwheel for driving the rotation of the rotating shaft is fixedly installed at the left end. A handwheel locking mechanism is disposed on the side of the left bearing plate and is used to lock the handwheel. The handwheel locking mechanism includes an auxiliary rod and a guide rod fixedly connected to the bearing plate, a slip ring slidably sleeved on the outside of the guide rod, an extension plate fixedly connected to the slip ring, a locking head connected to the extension plate for locking the handwheel, and a spring sleeved on the outside of the guide rod.

[0006] In this utility model, a T-shaped slider is fixedly installed on the rear side of the rack, and a T-shaped groove matching the T-shaped slider is provided on the front side of the vertical plate. The T-shaped slider is slidably embedded in the T-shaped groove.

[0007] In this invention, a first anti-slip pad is adhered to the opposite side of both the movable clamping plate and the fixed clamping plate, and the first anti-slip pad is located on the front side of the gear.

[0008] In this invention, the handwheel is provided with locking grooves at intervals on its side, and the locking grooves are distributed in a circular array. The locking head can be selectively inserted into any of the locking grooves to achieve locking.

[0009] In this invention, the spring is located between the slip ring and the bearing plate, and the side wall of the auxiliary rod is provided with a protrusion for limiting the extension plate.

[0010] This utility model also includes a mounting plate for mounting a monitor bracket. The rear side of the vertical plate is provided with threaded grooves spaced apart along its height direction. The mounting plate can be selectively mounted on the threaded grooves at different heights by means of wing bolts.

[0011] In this utility model, the left and right sides of the mounting plate are fixed ears, a second anti-slip pad is adhered to the top of the mounting plate, a screw is fixedly connected to the top of the mounting plate, and the surface of the second anti-slip pad is provided with a through hole for the screw to pass through.

[0012] In this invention, a wing nut is screwed onto the outer side of the screw, and an anti-slip washer is glued to the bottom of the wing nut.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] 1. Secure clamping and fall prevention: The gear and rack transmission mechanism generates a strong clamping force, which, together with the anti-slip pad, ensures that the clamp is firmly locked to the edge of the table, effectively preventing the monitor stand from falling due to accidental collision;

[0015] 2. Tool-free installation and easy operation: The entire installation and tightening process can be completed simply by turning the handwheel and the wing nut, without any additional tools, which greatly simplifies the installation process;

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please refer to Figures 1 to 6 A tool-free desktop quick-release clamp for a monitor stand includes a vertical plate 1. The front side of the vertical plate 1 has a clamping mechanism for clamping and fixing the vertical plate 1 to a desktop. The clamping mechanism includes a bearing plate 2 fixedly connected to the vertical plate 1, a rotating shaft 3 rotatably mounted on the bearing plate 2, a gear 4 fixedly mounted on the outside of the rotating shaft 3, a pair of racks 5 meshing with and symmetrically arranged with the gears 4, a connecting rod 6 fixedly connected between the left and right racks 5, a movable clamping plate 7 fixedly connected to the connecting rod 6, and a fixed clamping plate 8 fixedly connected to the vertical plate 1. In the middle, a handwheel 9 for driving its rotation is fixedly installed on the left end of the rotating shaft 3; a handwheel locking mechanism is provided on the side of the bearing plate 2 on the left side, the handwheel locking mechanism is used to lock the handwheel 9, the handwheel locking mechanism includes an auxiliary rod 10 and a guide rod 11 fixedly connected to the bearing plate 2, a slip ring 12 slidably sleeved on the outside of the guide rod 11, an extension plate 13 fixedly connected to the slip ring 12, a locking head 14 connected to the extension plate 13 for locking the handwheel 9, and a spring 15 sleeved on the outside of the guide rod 11.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a T-shaped slider 16 is fixedly installed on the rear side of the rack 5, and a T-shaped groove matching the T-shaped slider 16 is provided on the front side of the vertical plate 1. The T-shaped slider 16 is slidably embedded in the T-shaped groove, ensuring that the rack 5 can only move smoothly along a straight line, making torque transmission more efficient and the clamping process smoother. A first anti-slip pad is adhered to the opposite side of both the movable clamping plate 7 and the fixed clamping plate 8. The first anti-slip pad is located on the front side of the gear 4. The first anti-slip pad increases the friction with the tabletop, preventing slippage and avoiding scratches to the tabletop paint surface caused by the clamping force.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, the handwheel 9 has locking slots spaced apart on its side, arranged in a circular array. The locking head 14 can be selectively inserted into any of the locking slots to achieve locking. The multi-locking slot design allows for finding the corresponding locking position under any clamping force, making it more adaptable. The spring 15 is located between the slip ring 12 and the bearing plate 2. The side wall of the auxiliary rod 10 has a protrusion for limiting the extension plate 13. The protrusion limits the extension plate 13 when unlocking, keeping it in the unlocked state for easy operation.

[0033] like Figure 4 As shown, the system also includes a mounting plate 17 for mounting a monitor stand. The rear side of the vertical plate 1 has threaded grooves 19 spaced apart along its height. The mounting plate 17 can be selectively mounted on the threaded grooves 19 at different heights using wing bolts 18, thus adjusting the monitor stand height to meet the viewing height requirements of different users. The mounting plate 17 has fixing ears on both its left and right sides for easy installation. A second anti-slip pad is adhered to the top of the mounting plate 17, and a screw 20 is fixedly connected to the top of the mounting plate 17. The surface of the second anti-slip pad has through holes for the screw 20 to pass through. A wing nut 21 is screwed to the outside of the screw 20, and an anti-slip washer is adhered to the bottom of the wing nut 21. By tightening the wing nut 21, the base plate of the monitor stand can be firmly pressed onto the mounting plate 17. The second anti-slip pad and the anti-slip washer enhance the anti-slip effect and connection stability.

[0034] Working process: First, place the product on the edge of the table, so that the table is between the movable clamp 7 and the fixed clamp 8. (Unlock) Then push the slip ring 12 of the handwheel locking mechanism away from the handwheel 9. This will compress the spring 15. Then rotate the slip ring 12 and release it. The extension plate 13 will abut against the side of the protrusion of the auxiliary rod 10, which can keep the locking head 14 out of the locking groove of the handwheel 9 (e.g. Figure 7As shown), the handwheel 9 can be unlocked (clamped). Then, rotating the handwheel 9 of the clamping mechanism can drive the rotating shaft 3 and gear 4 to rotate. The gear 4 can drive the movable clamping plate 7 to move towards the fixed clamping plate 8 until it tightly clamps the desktop, effectively preventing the monitor bracket from falling due to accidental collision (locking). Then, rotate the slip ring 12 in the opposite direction to make the extension plate 13 disengage from the protrusion of the auxiliary rod 10. The spring 15 resets and drives the locking head 14 to insert into the locking groove of the handwheel 9. After clamping, it can effectively prevent the handwheel 9 from accidentally reversing due to accidental contact, which would reduce the clamping force and ensure high safety. Then, select the screw groove 19 at a suitable height on the vertical plate 1 to install the wing bolt 18 and the mounting plate 17. Then, pass the screw 20 through the rotating fixing hole of the monitor bracket. After adjusting the angle of the monitor bracket, tighten the wing nut 21 to abut and fix the base plate of the monitor bracket. This allows the product to flexibly adjust the installation height and viewing angle of the monitor bracket, making it highly practical.
