Description

Technical Field

[0001] This utility model belongs to the technical field of fixing components, specifically relating to a graphics card fixing device with multi-angle adjustment. Background Technology

[0002] A graphics card mounting device is an auxiliary accessory designed to solve the problem of PCB board bending or interface stress caused by the weight of modern high-performance graphics cards (especially large-size, heavy flagship models). Its core function is to rigidly connect the rear or middle of the graphics card to the chassis frame or motherboard tray through a physical support structure, thereby distributing the vertical load of the graphics card on the PCIe slot.

[0003] Currently, the support structure cannot fit tightly with the graphics card or case, resulting in uneven stress. This causes the graphics card to bear extra pressure in certain areas, which may lead to PCB deformation, loosening of fixing screws, or even detachment of the support device in the long run. It will also reduce compatibility with graphics cards of different sizes. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle adjustable graphics card fixing device, which aims 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 multi-angle adjustable graphics card mounting system, including:

[0007] The support mechanism includes a support rod, an end buffer assembly disposed on the top of the support rod, and a support assembly disposed on the top of the end buffer assembly;

[0008] Angle adjustment mechanism includes a limiting shaft seat sleeved on the outside of the support rod, a first connecting seat fixedly installed at one end of the support rod, a second connecting seat hinged to the first connecting seat, and a connecting shaft rotatably installed at the bottom of the second connecting seat;

[0009] And, an installation mechanism used in conjunction with the support mechanism.

[0010] As a preferred embodiment of this utility model, the angle adjustment mechanism further includes a knob fixedly installed at the bottom of the connecting shaft, and a support turntable hinged to the bottom of the knob.

[0011] As a preferred embodiment of the present invention, the end buffer assembly includes a rotating head that is movably engaged at the other end of the support rod, and a housing that is fixedly mounted on the top of the rotating head.

[0012] As a preferred embodiment of the present invention, the end buffer assembly further includes a miniature pneumatic damper fixedly installed in the inner cavity of the shell, and a connecting piece fixedly installed on the top of the miniature pneumatic damper.

[0013] As a preferred embodiment of this utility model, the support assembly includes a positioning piece fixedly installed on the top of the connecting piece, an anti-slip ring fixedly installed on the top of the positioning piece, a through hole opened in the center of the top of the positioning piece, and a bolt threaded into the inner cavity of the through hole, the bolt being threadedly connected to one side of the connecting piece.

[0014] As a preferred embodiment of this utility model, the installation mechanism includes a connecting rod fixedly installed on the outside of the limiting shaft seat, a limiting ring fixedly installed on the outside of the connecting rod, and a ball head fixedly installed on the end of the connecting rod.

[0015] As a preferred embodiment of the present invention, the mounting mechanism further includes a joint seat sleeved on the outside of the ball head, and a mounting plate fixedly installed on the outside of the joint seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the angle adjustment mechanism, in conjunction with the support mechanism, can achieve angle adjustment, ensuring that the anti-slip ring of the support component is fully in contact with the backplate of various graphics cards.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example

[0030] Reference Figures 1-4 This is an embodiment of the present invention, which provides a multi-angle adjustable graphics card fixing device, including,

[0031] The support mechanism 100 includes a support rod 110, an end buffer assembly 120 disposed on the top of the support rod 110, and a support assembly 130 disposed on the top of the end buffer assembly 120.

[0032] Angle adjustment mechanism 200 includes a limiting shaft seat 210 sleeved on the outside of the support rod 110, a first connecting seat 220 fixedly installed at one end of the support rod 110, a second connecting seat 230 hinged to the first connecting seat 220, and a connecting shaft 240 rotatably installed at the bottom of the second connecting seat 230.

[0033] And, the installation mechanism 300 used in conjunction with the support mechanism 100.

[0034] The support mechanism 100 and the angle adjustment mechanism 200 work together to achieve multi-angle free adjustment of the graphics card fixing device. The end buffer component 120 can absorb the vibration of the graphics card, while the mounting mechanism 300 ensures stable installation, adapts to different chassis structures, and reduces long-term stress damage to the PCIe slot.

[0035] Specifically, the angle adjustment mechanism 200 also includes a knob 250 fixedly mounted on the bottom of the connecting shaft 240, and a support turntable 260 hinged to the bottom of the knob 250.

[0036] The hinged design of the knob 250 and the support turntable 260 provides a quick locking function. Users can adjust and fix the support angle with one hand using the knob 250, while the support turntable 260 enhances the contact stability with the chassis and prevents slippage.

[0037] Furthermore, the end buffer assembly 120 includes a rotating head 121 movably mounted on the other end of the support rod 110, and a housing 122 fixedly mounted on the top of the rotating head 121. The end buffer assembly 120 also includes a miniature pneumatic damper 123 fixedly mounted in the inner cavity of the housing 122, and a connecting piece 124 fixedly mounted on the top of the miniature pneumatic damper 123.

[0038] The combination of the rotating head 121 and the housing 122 allows the end buffer assembly 120 to adapt to the tilt angle of the graphics card, avoiding PCB deformation caused by hard contact. At the same time, the housing 122 protects the internal structure from dust interference. The miniature pneumatic damper 123 dynamically compensates for the small displacement caused by thermal expansion and contraction during the operation of the graphics card. The connecting piece 124 evenly distributes the pressure, further reducing the risk of fatigue at the graphics card solder joints.

[0039] Preferably, the support assembly 130 includes a positioning piece 131 fixedly mounted on the top of the connecting piece 124, an anti-slip ring 132 fixedly mounted on the top of the positioning piece 131, a through hole 133 opened in the center of the top of the positioning piece 131, and a bolt 134 threadedly mounted in the inner cavity of the through hole 133, the bolt 134 being threadedly connected to one side of the connecting piece 124.

[0040] The anti-slip ring 132 and the bolt 134 work together to ensure that the support component 130 fits tightly against the graphics card backplate without scratching the surface. The through hole 133 design allows for fine adjustment of the tightening depth of the bolt 134 to accommodate graphics cards of different thicknesses.

[0041] Furthermore, the mounting mechanism 300 includes a connecting rod 310 fixedly mounted on the outside of the limiting shaft seat 210, a limiting ring 320 fixedly mounted on the outside of the connecting rod 310, and a ball head 330 fixedly mounted on the end of the connecting rod 310. The mounting mechanism 300 also includes a joint seat 340 sleeved on the outside of the ball head 330, and a mounting plate 350 fixedly mounted on the outside of the joint seat 340.

[0042] The combination of connecting rod 310 and ball head 330 allows the mounting mechanism 300 to be flexibly adjusted and fixed in position. Limiting ring 320 prevents the connecting rod 310 from excessively shifting, ensuring that the support mechanism 100 is always within the effective working range. Joint seat 340 wraps around ball head 330 to achieve multi-directional locking. Mounting plate 350 is fixed to chassis through standard screw holes, taking into account both rigid support and quick disassembly and assembly requirements, making it suitable for users who frequently upgrade hardware.

[0043] During use, during installation, the device is first fixed in a suitable position on the chassis using the mounting plate 350 of the mounting mechanism 300. After adjusting the connecting rod 310 and ball head 330 to determine the general orientation of the bracket, the knob 250 of the angle adjustment mechanism 200 is rotated to loosen the connecting shaft 240, allowing the support rod 110 to be freely adjusted in angle. After the graphics card is installed in place, the support mechanism 100 is moved to make the anti-slip ring 132 of the support component 130 fit tightly against the backplate of the graphics card. The support force is then finely adjusted using the bolt 134. The locking knob 250 is tightened to fix the angle. At this time, the miniature pneumatic damper 123 of the end buffer component 120 starts to work, continuously absorbing the vibration during the operation of the graphics card and compensating for thermal deformation, thus achieving rapid installation, multi-angle adaptive adjustment, and continuous and stable support protection.

[0044] In summary, through the coordinated design of the support mechanism 100, the angle adjustment mechanism 200, and the mounting mechanism 300, comprehensive functional optimization is achieved. The end buffer component 120 and the support component 130 of the support mechanism 100 effectively absorb the vibration of the graphics card and disperse the pressure, protecting the graphics card PCB and solder joints. The angle adjustment mechanism 200 provides stable and reliable multi-angle support and adjustment capabilities through multi-joint linkage and knob 250 locking design. The mounting mechanism 300 adopts a combination of ball head 330 and joint seat 340 to achieve flexible positioning while ensuring overall stable installation.
