Abstract
Description
Technical Field
[0001] This invention relates to the field of server equipment technology, specifically to a screwless server handle strip. Background Technology
[0002] With the rapid development of data center and cloud computing technologies, server equipment is evolving towards higher density, modularity, and high availability. Against this backdrop, the efficiency of equipment maintenance and replacement within server racks has become a key factor affecting data center operation and maintenance costs and business continuity. In traditional server installation methods, servers are commonly fixed directly to rack rails or trays using screws. While this method is secure and reliable, during hardware upgrades, troubleshooting, or routine maintenance, operators need to use specialized tools to tighten or loosen multiple screws, a cumbersome and time-consuming process that not only increases the workload of maintenance personnel but also extends server downtime.
[0003] To address this issue, some tool-free installation solutions have emerged in the market, such as those using snap-fit, spring clips, or quick-lock mechanisms. However, existing solutions often have the following limitations: First, some simple snap-fit structures provide insufficient locking force, which may cause the server to loosen during equipment vibration or accidental impact, posing a safety hazard; second, while some complex quick-release devices offer reliable locking, they are expensive or have poor compatibility with standard server racks, making large-scale deployment difficult and increasing system complexity and cost. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a screwless server handle strip.
[0005] The objective of this invention is achieved through the following technical solution:
[0006] A screwless server handle includes a mounting frame, the mounting frame having a first receiving cavity for accommodating a server, a support strip being installed at the bottom of the first receiving cavity, and at least one first limiting component for restricting server displacement being installed on each of the two opposite outer side walls of the mounting frame.
[0007] The first limiting component includes an elastic limiting piece, a first pin, and two receiving boxes. The mounting frame has symmetrically opened inclined grooves on its side.

[0011] The second limiting component includes two symmetrically distributed elastic plates. The middle part of the elastic plate is fastened to the side of the mounting frame by a fixing screw. A pin is installed at the end of the elastic plate. A through hole is opened on the side wall of the mounting frame for the pin to pass through. The pin is used to pass through the through hole and then insert into the pin hole on the side of the server.
[0012] Preferably, a cover plate is fixedly connected to the side of the mounting frame, the cover plate is used to connect the cabinet side panel, and a cabinet support frame is fixed to the inner wall of the cabinet side panel.
[0013] Preferably, it further includes an anti-derailment moving component, which is used to be installed on the cabinet support frame and connected to the mounting frame to drive its front and rear displacement.
[0014] Preferably, the anti-derailment moving assembly includes a first housing fixedly connected to the cabinet support frame and a second housing fixedly connected to the side of the mounting frame;
[0015] A first guide rail is horizontally installed inside the first housing, and a second guide rail is horizontally installed inside the second housing. The second housing is slidably connected to the first housing.
[0016] The bottom of the first housing and the top of the second housing are respectively provided with movable grooves. A slide assembly is provided between the first guide rail and the second guide rail. The top of the slide assembly is slidably connected to the first guide rail, and the bottom of the slide assembly is slidably connected to the second guide rail.
[0017] Preferably, the slide assembly includes a first connecting bracket, with a second connecting bracket fixedly connected to each of the four corners of the first connecting bracket, and a rotatable V-shaped guide wheel installed on each of the upper and lower sides of the second connecting bracket. The two V-shaped guide wheels located on the same second connecting bracket respectively roll in contact with the upper and lower sides of the first guide rail or the second guide rail.
[0018] Preferably, the anti-derailment moving assembly further includes a first driving assembly, the first driving assembly including a third housing fixedly connected to the bottom of the first housing, the third housing having a winding wheel and a right-angle shaft reduction motor for driving the winding wheel to rotate, the winding wheel having a traction rope wound on it, the first housing having a pulley installed inside it, the traction rope passing through the first housing and around the pulley, and then being fixedly connected to the side of the first connecting bracket of the slide assembly.
[0019] Preferably, a rack is horizontally installed inside the first housing;
[0020] The slide assembly includes a first connecting bracket, and a second connecting bracket is fixedly connected to each of the top two sides of the first connecting bracket.

[0023] The cabinet support frame is equipped with a cabinet back cover, and the cabinet back cover has a second strip-shaped through groove, which allows the mounting frame to pass through.
[0024] The beneficial effects of this invention are:
[0025] I. This invention provides a screwless fixing structure. When the server is pushed into the mounting frame, its side presses against the contact portion of the elastic limiting piece, forcing the elastic limiting piece to deform laterally and displace longitudinally under its own elasticity and the guidance of the first pin, thereby automatically clamping the server. This achieves "plug and hold" for the server, eliminating the need for tools during installation, greatly simplifying the operation steps, and improving installation and disassembly efficiency. The structure is simple and easy to implement, solving the problem of cumbersome traditional screw fixing.
[0026] Second, a precision buffering and force-amplifying mechanism consisting of a guide shaft, sleeve, connecting shaft, and spring is added. The spring force and the elastic limit plate's own elastic force are superimposed, significantly enhancing the clamping force's strength, stability, and adjustability. This more effectively resists vibration, prevents loosening, and avoids excessive initial pressure damaging the server, thus improving the reliability and durability of the fixing system.
[0027] Third, a second limiting assembly consisting of a flexible plate, fixing screws, and pins is added, providing an independent physical locking mechanism as a powerful supplement to the elastic clamping. This mechanical interlock provides a higher level of safety, effectively preventing server displacement under extreme conditions, and is suitable for harsh environments with extremely high requirements for fixed reliability.
[0028] IV. The mounting frame and cabinet are connected by an anti-derailment moving component (including a slide and guide rail), and the traction rope is wound and released by a motor-driven winding wheel, realizing automated pulling of the server and achieving convenient operation from fixed to moving. Fixed installation requires no tools, and moving can be controlled electrically with one button, greatly reducing the physical burden on maintenance personnel and improving operational accuracy and efficiency. It is particularly suitable for high-density deployment and cabinet environments that require frequent maintenance. Attached Figure Description

[0039] Example 1:
[0040] like Figures 1-3 As shown, this embodiment provides a screwless server handle strip, which mainly consists of a mounting frame 1. The mounting frame 1 has a rectangular first receiving cavity inside, specifically for placing the server body. To support the server and prevent it from sagging, a support strip 2 is fixedly installed at the bottom of the first receiving cavity.
[0041] To achieve screwless and rapid fixing, at least one first limiting component 3 is installed on the outer walls of both the left and right sides of the mounting frame 1. The core of each first limiting component 3 is a U-shaped elastic limiting piece 31. Symmetrical inclined grooves 101 are formed on the sides of the mounting frame 1, and two receiving boxes 33 are fixed to the outer side of the mounting frame 1. The extensions at both ends of the elastic limiting piece 31 pass through these two inclined grooves 101 and are inserted into the corresponding receiving boxes 33. Simultaneously, the elastic limiting piece 31 has an inwardly protruding contact portion 311 in its center.
[0042] When the server is horizontally inserted into the first receiving cavity of the mounting frame 1, its sides press against the contact portion 311 of the elastic limiting piece 31. Since both ends of the elastic limiting piece 31 are constrained by the receiving box 33, the pressure in the middle forces the elastic limiting piece 31 to undergo lateral elastic deformation. Simultaneously, guided by the first pin 32 passing through the first strip-shaped through-slot 312 on the elastic limiting piece 31, both ends of the elastic limiting piece 31 will experience slight longitudinal displacement along the inclined groove 101. This combined action of "lateral deformation generating clamping force" and "longitudinal displacement adapting to the insertion process" allows the elastic limiting piece 31 to automatically and tightly abut against the side of the server, firmly securing it within the mounting frame 1 without the need for any screws.
[0043] This embodiment achieves "plug-and-play" server installation through the aforementioned flexible limiting structure. The installation process requires no tools; simply pushing the server in completes the fixation, simplifying the operation and improving maintenance efficiency. It is suitable for scenarios requiring frequent server hardware replacements.
[0044] Example 2:
[0045] This embodiment optimizes the structure of the receiving box 33 based on embodiment 1, such as... Figure 4 As shown, the housing 33 includes a closed housing 331. A guide shaft 333 is fixed to each of the upper and lower inner walls of the housing 331. A sleeve 334, which can slide along each guide shaft 333, is fitted onto each guide shaft 333. The upper and lower sleeves 334 are rigidly connected as one unit by a connecting shaft 335. The end of an elastic limiting piece 31 inserted into the housing 331 is fixed to the connecting shaft 335. Furthermore, a spring 332, in a compressed or pre-tightened state, is connected between the inner wall of the housing 331 (e.g., the left side wall) and the connecting shaft 335.
[0046] When the server is inserted and presses against the elastic limiting piece 31, the force is transmitted to the sleeves 334 on both sides through the connecting shaft 335, causing them to slide along the guide optical axis 333 and further compress the spring 332. Once the server is in place, the potential energy stored in the spring 332 is converted into a reverse thrust, which is evenly applied to both ends of the elastic limiting piece 31 through the connecting shaft 335 and the sleeves 334. This additional spring force, combined with the elastic force of the elastic limiting piece 31 itself, acts on the sides of the server, providing a stronger, more stable, and adjustable clamping force.
[0047] This embodiment significantly enhances the clamping effect and reliability of the first limiting component by introducing a precision buffering and force-amplifying mechanism consisting of a "guide optical axis-sleeve-spring". The spring force makes the fixation more secure and effectively resists vibration; at the same time, this structure makes the clamping force controllable, ensuring both fixation strength and preventing damage to the server casing due to excessive initial deformation pressure.
[0048] Example 3:
[0049] This embodiment adds an auxiliary mechanical locking device, namely a second limiting component 6, to embodiment 1 or 2. The second limiting component 6 and the first limiting component 3 are spaced apart along the length of the mounting frame 1, as shown below. Figure 4 As shown. This assembly is mounted on the outer wall of the mounting frame 1 and includes two symmetrically distributed elastic plates 62 (such as metal springs). The middle of each elastic plate 62 is fastened to the mounting frame 1 by a fixing screw 63, so that its end can be turned like a lever. A pin 61 is installed at the end of the elastic plate 62. Correspondingly, a through hole 102 is formed in the side wall of the mounting frame 1.
[0050] Pin holes are pre-set at corresponding positions on the side of the server. After the server is inserted into the mounting frame 1 and initially fixed by the first limiting component 3, the operator can manually push the pins 61 on both sides into the through holes 102, and finally insert them into the pin holes of the server. Due to the elasticity of the elastic plate 62, the pins 61 can maintain a stable locked state. When disassembly is required, simply use your fingers to simultaneously push the free ends of the two elastic plates 62 outwards to disengage the pins 61 from the pin holes of the server, and then the server can be pulled out.
[0051] This embodiment provides a physical locking mechanism as a supplement to elastic clamping. The second limiting component 6 is equivalent to a manually operated "safety bolt," providing absolutely reliable mechanical interlocking to prevent the server from shifting under extreme vibration or accidental pulling, further enhancing the security of the equipment fixation, and is suitable for environments with extremely high reliability requirements.
[0052] Example 4:
[0053] This embodiment integrates screwless fixing and electric sliding functions into one unit. For example... Figures 6-8 As shown, a cover plate 7 is fixedly connected to the side of the mounting frame 1. The cover plate 7 is used to connect the cabinet side panel 9. A cabinet support frame 10 is fixed to the inner wall of the cabinet side panel 9. Based on the mounting frame 1 being connected to the cabinet through the cover plate 7, the entire handle strip device also includes a set of anti-derailment moving components 8.
[0054] The anti-derailment moving assembly 8 includes a first housing 81 fixed to the cabinet support frame 10 and a second housing 82 that slides relative to the first housing 81. The first housing 81 contains a first guide rail 83, and the second housing 82 contains a second guide rail 84. A sliding assembly 85 is located between the two, with a V-shaped guide wheel 851 at its top engaging with the first guide rail 83 and a V-shaped guide wheel 851 at its bottom engaging with the second guide rail 84, thereby enabling the second housing 82 (which drives the mounting frame 1 and the server) to slide smoothly relative to the first housing 81 (fixed to the cabinet).
[0055] To reliably lock the server when it is pulled out or pushed into its extreme position, preventing accidental slippage, a first drive assembly 86 is also provided. This includes a third housing 861 mounted at the bottom of the first housing 81, housing a right-angle shaft geared motor 862 and a winding reel 863. The right-angle shaft geared motor 862 drives the winding reel 863 to wind and unwind a traction rope 864. The traction rope 864 passes around a pulley inside the first housing 81 and is finally fixed to the first connecting bracket 852 of the slide assembly 85. Activating the right-angle shaft geared motor 862 automatically pulls the server out or pushes it into the rack by wind and unwinding the rope.
[0056] This embodiment simplifies the entire process of server installation, fixing, and removal. Fixing relies on flexible limiters, requiring no tools; moving is achieved through electric control with one-button operation, making it particularly suitable for high-density server rack deployments. It significantly reduces the physical burden on maintenance personnel and improves operational accuracy and efficiency.
[0057] Example 5:
[0058] This embodiment provides another high-precision, high-load electric translation solution. For example... Figure 9 As shown, a horizontal rack 874 is fixedly installed inside the first housing 81 of its anti-derailment moving assembly 8.
[0059] The slide assembly 85 has an internal receiving slot that integrates the second drive assembly 87. This drive assembly includes a helical gear 871 that precisely meshes with a rack 874, a worm gear 872 that meshes perpendicularly with the helical gear 871, and a servo motor 873 that drives the worm gear 872. The slide assembly 85 is rollably connected to the second guide rail 84 within the second housing 82 via a set of V-shaped guide wheels 851 at its top.
[0060] During operation, the servo motor 873 drives the worm gear 872 to rotate, which in turn drives the helical gear 871 to rotate. Since the helical gear 871 meshes with the fixed rack 874, according to the gear and rack transmission principle, the slide assembly 85 will move linearly along the rack 874, thereby driving the mounting frame 1 and the server to move back and forth through its connection with the second housing 82. The worm gear pair has a reverse self-locking characteristic and can reliably stop at any position.
[0061] This embodiment employs a transmission scheme of "servo motor + worm gear + rack and pinion," which offers advantages such as high transmission accuracy, strong load-bearing capacity, smooth operation, precise positioning, and power-off self-locking. It is particularly suitable for heavy-duty servers or applications requiring precise control of the pull-out position (such as docking with backplane interfaces).
[0062] Example 6: This example focuses on facilitating manual pulling of the installation frame 1, such as... Figure 1As shown. On the front of the mounting frame 1, a handle 4 that can flip left and right is mounted via a hinge 5. The hinge 5 can be a hinge or a pivot structure.
[0063] Under normal conditions, when the server is fully pushed into the rack, handle 4 can be flipped inward to fit against the mounting frame 1, keeping the front of the rack flat, saving space and maintaining a neat appearance. When manual operation of the server is required, flipping handle 4 outward provides a comfortable point of leverage, making it easy for maintenance personnel to manually pull out or push the server in.
