Description

Technical Field

[0001] This utility model relates to the field of server slide rail technology, and in particular to a chassis slide rail locking mechanism. Background Technology

[0002] Slide rails, as a common mechanical component, are widely used in various scenarios requiring sliding functionality, such as server racks. Server chassis are connected to the rack via slide rails, allowing them to be pulled out or moved into the rack. Currently, some chassis are directly connected to the slide rails using fasteners, requiring tools for connection and disassembly, thus compromising ease of installation and removal. Other chassis use quick-positioning mechanisms, but these mechanisms suffer from poor stability. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a chassis slide rail locking mechanism that is easy to use and has good stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A chassis slide rail locking mechanism includes an inner rail and a locking assembly disposed on the outer side of the inner rail. The inner rail has a limiting groove that penetrates the upper edge of the inner rail. The locking assembly includes a fixing part and a locking part that is elastically deformable relative to the fixing part. The fixing part is fixedly connected to the outer side of the inner rail. The locking part has a locking hole corresponding to the bottom of the limiting groove. The upper end of the locking part has an inclined guide part. The end of the locking part away from the fixing part has an unlocking part. When a limiting pin on the chassis is engaged into the limiting groove from the upper end of the limiting groove, the limiting pin contacts the guide part and drives the locking part to elastically deform outward. When the limiting pin enters the bottom of the limiting groove, the locking part elastically resets, causing the locking hole to fit onto the limiting pin and lock the limiting pin. When the unlocking part is manually pushed outward, causing the locking part to elastically deform, the limiting pin is released from locking.

[0006] By adopting the above technical solution: when the limiting pin of the chassis is inserted from the upper end of the limiting groove, the guide part is pressed, causing the locking part to elastically deform and avoid the limiting pin. When the limiting pin is fully inserted into the bottom of the limiting groove, the position of the limiting pin corresponds exactly to the locking hole. The locking part loses the support of the limiting pin and returns to its initial state. At this time, the limiting pin is locked and limited by the locking hole and cannot be dislodged from the limiting groove. When it is necessary to remove the chassis, the unlocking part is manually pushed outward to dislodge the limiting pin from the limiting groove from bottom to top. This locking mechanism is convenient to use and has good stability.

[0007] Preferably, the locking assembly is configured as an elastic metal sheet, the fixing part and the locking part are configured as an integral structure, the guide part is formed by bending the upper end of the locking part outward, and the unlocking part is formed by bending the end of the locking part outward. Both the guide part and the unlocking part are directly formed by bending the elastic metal sheet, resulting in an integral structure that is easy to manufacture and low in cost.

[0008] Preferably, the lower end of the locking portion has bent portions symmetrically distributed with the guide portion. The bent portions enhance the strength of the locking portion.

[0009] Preferably, the limiting groove is configured as a V-shaped groove, and a clearance notch is provided at the upper end of the inner rail corresponding to the opening end of the V-shaped groove. The clearance notch is larger in the length direction of the inner rail than the width of the opening end of the V-shaped groove, and the guide part is located directly below the clearance notch. The clearance notch is used to avoid the end of the limiting pin, so that when the limiting pin descends in the vertical plane, it can push the guide part, thereby causing the locking part to elastically deform and smoothly enter the limiting notch, eliminating the need for repeated adjustment of the initial position of the limiting pin.

[0010] Preferably, the locking hole is configured with an oblong shape distributed along the sliding direction of the inner rail. The oblong shape allows for a larger gap between the limiting pin and the locking hole in the length direction, thereby reducing the accuracy requirements for fixing the locking assembly to the inner rail.

[0011] Preferably, the fixing part has a first connecting seat at one end facing the locking part, and the locking part has a second connecting seat at the other end facing the fixing part, which is rotatably connected to the outside of the first connecting seat. An elastic element is provided between the first and second connecting seats, and the outer end of the elastic element abuts against the second connecting seat, so that the locking hole is fitted onto the outside of the limiting pin. When the guide part is pressed, the locking part can rotate relative to the fixing part, and the limiting pin can be stably reset by the elastic element after entering the locking hole. This structure further improves the convenience and stability of use.

[0012] Preferably, a clearance hole is provided on the inner rail corresponding to the first connecting seat, and the first connecting seat enters the clearance hole. The outer surface of the locking part is coplanar with the outer surface of the fixing part. This arrangement makes the outer surface of the locking assembly flatter and the dimension extending beyond the outer surface of the inner rail smaller, thereby preventing interference with the middle rail.

[0013] Preferably, the elastic element is configured as a compression spring, and a positioning protrusion extending into the compression spring is provided on the outer surface of the first connecting seat. The positioning protrusion positions the compression spring to prevent it from dislodging.

[0014] Therefore, this utility model has the advantages of being easy to use and having good stability. Attached Figure Description

[0023] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0024] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0025] Example 1: As Figures 1-5The diagram illustrates a chassis slide rail locking mechanism, comprising an inner rail 1 and a locking assembly 2 disposed on the outer side of the inner rail 1. The inner rail 1 has a limiting groove 10 that penetrates its upper edge. The locking assembly 2 includes a fixing part 20 and a locking part 21 that is elastically deformable relative to the fixing part 20. The fixing part 20 is fixedly connected to the outer surface of the inner rail 1. The locking part 21 has a locking hole 210 corresponding to the bottom of the limiting groove 10. The upper end of the locking part 21 has an inclined guide part 211. An unlocking part 212 is provided at the end of the upper part away from the fixed part 20; when the limiting pin 3 on the chassis is inserted into the limiting groove 10 from the upper end of the limiting groove 10, the limiting pin 3 contacts the guide part 211 and drives the locking part 21 to elastically deform outward; when the limiting pin 3 enters the bottom of the limiting groove 10, the locking part 21 elastically resets so that the locking hole 210 is sleeved on the limiting pin 3 to lock the limiting pin 3; when the unlocking part 212 is manually pushed outward to make the locking part 21 elastically deform, the limiting pin 3 is released from locking.

[0026] like Figure 5 As shown, the circumferential surface of the limiting pin 3 is provided with an annular groove 30, so that when the limiting pin is inserted into the limiting groove, both sides of the limiting groove will be inserted into the annular groove 30, thereby limiting the axial movement of the limiting pin.

[0027] The locking assembly 2 is configured as an elastic metal sheet, the fixing part 20 and the locking part 21 are configured as an integral structure, the guide part 211 is formed by bending the upper end of the locking part 21 outward, and the unlocking part 212 is formed by bending the end of the locking part 21 outward; the lower end of the locking part 21 is provided with a bent part 213 symmetrically distributed with the guide part 211.

[0028] The limiting groove 10 is configured as a V-shaped groove. The upper end of the inner rail 1 is provided with a clearance notch 11 corresponding to the opening end of the V-shaped groove. The clearance notch 11 is larger than the width of the opening end of the V-shaped groove in the length direction of the inner rail 1. The guide part 211 is located directly below the clearance notch 11. The locking hole 210 is configured with waist-shaped holes distributed along the sliding direction of the inner rail 1.

[0029] Example 2: Figures 6-8 As shown, a first connecting seat 22 is provided at one end of the fixing part 20 facing the upper locking part 21, and a second connecting seat 23 is provided at one end of the locking part 21 facing the fixing part 20, which is rotatably connected to the outside of the first connecting seat 22. An elastic member 24 is provided between the first connecting seat 22 and the second connecting seat 23, and the outer end of the elastic member 24 abuts against the second connecting seat 23, so that the locking hole 210 is sleeved on the outside of the limiting pin 3. A clearance hole 12 is provided on the inner rail 1 at the corresponding position of the first connecting seat 22, and the first connecting seat 22 enters into the clearance hole 12. The outer surface of the locking part 21 is coplanar with the outer surface of the fixing part 20.

[0030] In some embodiments, the elastic element 24 is configured as a compression spring, and a positioning protrusion 220 extending into the compression spring is provided on the outer side of the first connecting seat 22.

[0031] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 2 and Figure 5 For example, the limiting pin 3 on the chassis enters the limiting groove 10 downwards from the clearance notch 11. First, the end of the limiting pin 3 contacts the inclined guide part 211. The guide part is pressed and causes the locking part to bend and deform. Then, the limiting pin 3 can smoothly enter the bottom of the limiting groove 10. After the limiting pin 3 enters the bottom of the limiting groove, the position of the locking hole corresponds to the limiting pin. The locking part resets due to the loss of the support of the limiting pin, so that the locking hole is fitted onto the limiting pin. The axial direction of the limiting pin is limited by the locking of the annular groove 30 and the limiting groove. The vertical direction of the limiting pin is limited by the locking hole. When it is necessary to remove the limiting pin 3 from the inner rail of the chassis, the unlocking part 212 is manually pushed outwards. At this time, the limiting pin is dislodged from the locking hole. Then, the limiting pin can be moved out of the limiting groove from bottom to top to achieve unlocking. The locking and unlocking of the limiting pin are very convenient.

[0032] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solution of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of this utility model.

[0033] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
