Description

Technical Field

[0001] This invention relates to the technical field of slide rails, specifically a server slide rail with an opening and locking function. Background Technology

[0002] Server rack slide rails are metal components installed inside server racks. Their main function is to support and secure server equipment, ensuring their safe and stable placement on the rack. These slide rails consist of outer rails, middle rails, and inner rails. The outer rails are mounted on the side walls of the rack, the inner rails are mounted on the left and right sides of the server equipment drawer, and the middle rail, acting as a load-bearing rail, slides between the inner and outer rails to extend the drawer's range of motion and allow the inner and middle rails to slide back and forth relative to the outer rail along its axis. Furthermore, for smoother sliding, external beadlocks and internal beadlocks are typically added between the middle, outer, and inner rails. This design allows the server slide rails to withstand heavier loads and facilitates server installation and removal through a sliding mechanism.

[0003] However, the aforementioned server rack slide rails have the following shortcomings in practical applications: 1) When the existing server rack slide rails are open, they lack a locking function. Under heavy load, the inner rails may tilt and slide inward, causing the server to shut down accidentally. This results in poor stability and poses a significant safety hazard.

[0004] 2) Existing server rack slide rails are equipped with a stop component for opening and stopping. However, this stop component has many parts, complex transmission, and occupies a large amount of space. In addition, it only has a locking and stopping function but no reset function. Manually pressing the button on the stop component to unlock it and then pressing it back to the initial position is cumbersome and not conducive to the use of the slide rail. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a server slide rail with an opening and locking function. It has a simple structure, is safe and reliable with both opening and locking functions, and has a reset function for easy operation, improving the stability and smoothness of operation and ensuring the quality of product use.

[0006] The objective of this invention is achieved as follows: A server slide rail with an opening and locking function includes an outer rail, a middle rail, and an inner rail that are slidably connected in sequence. An outer bead socket group and an inner bead socket group are slidably connected between the middle rail and the outer and inner rails. The inner rail is provided with a locking mechanism that has a locking function in the open state. The locking mechanism includes a locking elastic handle group, a locking rod, a locking plate, and a locking elastic element. The limiting part of the locking elastic handle group is installed on the inner rail. One end of the locking elastic handle group is installed on one end of the locking rod. One end of the locking rod is elastically connected to the elastic part of the locking elastic handle group. The locking rod is slidably connected to the inner rail while simultaneously causing the locking plate to swing. One swing end of the locking plate has a locking interface that allows it to be fastened to or separated from the middle rail as it swings. The locking elastic element is installed on the inner rail, and its elastic arm is elastically connected to the other swing end of the locking plate.

[0007] Based on the above optimization, the locking elastic handle assembly includes a handle and a reset elastic element. The handle is installed at one end of the locking rod, and the handle is provided with a limiting block installed on the inner rail. The reset elastic element is fitted on the limiting block, and its two elastic ends are respectively connected to the limiting block and the handle.

[0008] Based on the above optimization, one end of the locking rod has an installation groove adapted for the disassembly and assembly of the handle, and the sides of the installation groove are respectively provided with snap-fit ​​protrusions, and the handle is provided with a snap-fit ​​position for snapping with the snap-fit ​​protrusions.

[0009] Based on the above optimization, the handle has a toggle groove for easy operation.

[0010] Based on the above optimization, a positioning pin for positioning and connecting to the inner rail is installed in the middle of the locking piece, the card interface is located on one side of one swing end of the locking piece, and a positioning protrusion for engaging or disengaging with the card interface is provided at the front end of the middle rail.

[0011] Based on the above optimization, one end of the locking plate is provided with a sliding groove for swinging around the positioning pin, and the other end of the locking rod is provided with a toggle pin for sliding connection with the sliding groove.

[0012] Based on the above optimization, the locking elastic element is equipped with a fixing pin fixed on the inner rail, and the elastic arm of the locking elastic element acts elastically on the other swing end of the locking piece.

[0013] Based on the above optimization, one end of the locking rod is provided with a guide groove for limiting linear movement, and the inner rail is provided with a guide pin for sliding connection with the guide groove.

[0014] Based on the above optimization, one side of the locking rod has an open guide groove for limiting linear movement, and the inner rail is provided with a connecting guide pin for sliding connection with the open guide groove.

[0015] The advantages of this invention are as follows: By adding a locking mechanism to the inner rail, and utilizing the structural cooperation of the locking mechanism's locking elastic handle assembly, locking rod, locking plate, and locking elastic element, the locking plate can be engaged with the middle rail by the elastic action of the locking elastic element when the slide rail is fully extended. This prevents the inner rail from opening and closing, achieving the locking function. The transmission is stable, safe, and reliable. When the locking elastic handle assembly is moved, the locking plate's locking interface disengages from the middle rail under the transmission action of the locking rod, unlocking the inner rail and allowing it to open and close freely. At this point, releasing the locking elastic handle assembly allows the locking rod to be pulled under the reset elastic action of the locking elastic handle assembly, causing the locking plate to automatically reset, achieving the reset function. This makes operation convenient, ensures smooth and stable operation, and guarantees the quality of product use. Attached Figure Description

[0020] Figure 5 This is an exploded view of the locking mechanism according to a preferred embodiment of the present invention. Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] According to the appendix Figures 1 to 5As shown, the server slide rail with opening and locking functions of the present invention includes an outer rail 1, a middle rail 2, and an inner rail 3 that are slidably connected in sequence. An outer beaded assembly 4 and an inner beaded assembly 5 are slidably connected between the middle rail 2 and the outer rail 1 and inner rail 3. The inner rail 3 is provided with a locking mechanism that has a locking function in the open state. The locking mechanism includes a locking elastic handle assembly 6, a locking rod 7, a locking piece 8, and a locking elastic element 9. The limiting part of the locking elastic handle assembly 6 is installed on the inner rail 3, and one end of the locking elastic handle assembly 6 is installed on one end of the locking rod 7. One end of the locking rod 7 is elastically connected to the elastic part of the locking elastic handle assembly 6. While the locking rod 7 is slidably connected to the inner rail 3, it simultaneously drives the locking piece 8 to swing. One swing end of the locking piece 8 has a locking interface 10 that is fastened to or separated from the middle rail 2 as it swings. The locking elastic element 9 is installed on the inner rail 3, and the elastic arm of the locking elastic element 9 is elastically connected to the other swing end of the locking piece 8.

[0023] With the slide rail fully extended, the elastic force of the locking elastic element 9 acts on the locking plate 8, causing the locking plate 8's locking interface 10 to engage with the middle rail 2, preventing the inner rail 3 from opening and closing, thus achieving the locking function. The transmission is stable and reliable. When the locking elastic handle group 6 is moved, under the transmission action of the locking rod 7, the locking interface 10 of the locking plate 8 is disengaged from the middle rail 2, allowing the inner rail 3 to unlock and open and close freely. At this time, releasing the locking elastic handle group 6 allows the locking rod 7 to be pulled under the reset elastic force of the locking elastic handle group 6, causing the locking plate 8 to automatically reset, achieving the reset function. This ensures convenient operation, smooth and stable operation, and guarantees the quality of product use.

[0024] Reference Figures 1 to 5 As shown, further detailed, the locking elastic handle assembly 6 includes a handle 61 and a reset elastic element 62. The handle 61 is installed at one end of the locking lever 7, and the handle 61 is provided with a limiting block 63 installed on the inner rail 3. The reset elastic element 62 is fitted onto the limiting block 63, and its two elastic ends are respectively connected to the limiting block 63 and the handle 61.

[0025] The locking rod 7 has a mounting groove 71 at one end for mounting and dismounting the handle 61. The mounting groove 71 has snap-fit ​​protrusions 72 on its sides, and the handle 61 has snap-fit ​​positions 64 for engaging with the snap-fit ​​protrusions 72. This design facilitates assembly, disassembly, maintenance, and replacement, ensuring product quality.

[0026] Furthermore, the handle 61 has a toggle groove 65 for easy operation. The toggle groove 65 makes it easy to move the handle 61, making operation convenient.

[0027] Reference Figures 1 to 5As shown in the figure, further detailed, the locking piece 8 is equipped with a positioning pin 11 for positioning and connecting to the inner rail 3 in the middle part, the card interface 10 is provided on one side of one swing end of the locking piece 8, and the front end of the middle rail 2 is provided with a positioning protrusion 21 for engaging or disengaging with the card interface 10.

[0028] The locking piece 8 has a sliding groove 81 at one end for swinging around the positioning pin 11, and a toggle pin 12 at the other end for sliding connection with the sliding groove 81. The locking elastic member 9 is equipped with a fixing pin 13 fixed on the inner rail 3, and the elastic arm of the locking elastic member 9 acts elastically on the other end of the locking piece 8.

[0029] That is, when the slide rail is fully extended, the locking interface 10 of the locking piece 8 is fastened to the positioning protrusion 21 of the middle rail 2. Due to the elastic action of the elastic arm of the locking elastic element 9 on the other end of the locking piece 8, the inner rail 3 cannot be opened or closed, thus realizing the unlocking and locking function. When the handle 61 is pulled through the actuating groove 65, the locking rod 7 can be moved. At this time, the actuating pin 12 moves in the sliding groove 81, thereby causing one swing end of the locking piece 8 to swing outward around the positioning pin 11, so that the locking interface 10 is disengaged from the positioning protrusion 21, thus unlocking the inner rail 3, which can be opened and closed freely. During this period, the reset elastic element 62 is in a compressed and stored energy state. When the handle 61 is released, the reset elastic element 62 releases energy and is in an extended state, thereby driving the locking rod 7 to reset, thereby pulling one swing end of the locking piece 8 to reset. At the same time, in conjunction with the elastic arm of the locking elastic element 9, the locking mechanism of this structure realizes the automatic reset function.

[0030] Additionally, one end of the locking rod 7 has a guide groove 74 for limiting linear movement, and the inner rail 3 has a guide pin 14 for slidingly connecting with the guide groove 74. One side of the locking rod 7 has an open guide groove 73 for limiting linear movement, and the inner rail 3 has a connecting guide pin 15 for slidingly connecting with the open guide groove 73.

[0031] The structure of guide pin 14, connecting guide pin 15, guide groove 74, and open guide groove 73 is used to ensure that the locking rod 7 can move linearly, restrict the movement position of the locking rod 7, improve the transmission stability and smoothness of the product, facilitate operation, ensure good locking effect, and guarantee product quality.

[0032] The above specific embodiments are merely specific implementations of the present invention with better effects. Any structure that is the same as or equivalent to the server slide rail with the opening and locking function of the present invention is within the protection scope of the present invention.
