[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example like Figure 1-3 As shown, an end connection structure for a slide rail includes a bracket 1, a bracket 2, and a spring 3 located on the outer side of the slide rail 10. The outer side of the slide rail 10 is the outer side of the outer rail of the slide rail. The bracket 1 is fixedly connected to the slide rail 10 and includes a bracket body 11 and a connecting plate 12 located at the front end of the bracket body 11. The connecting plate 12 has at least one forward-protruding positioning protrusion 13. In this embodiment, there are two positioning protrusions 13 located at both ends of the connecting plate 12, forming a mounting hole. The bracket 2 is stacked on the outer side of the bracket 1 and slidably connected to the bracket 1. The bracket 2 includes a bracket body 21 and a front end plate 22 located at the front end of the bracket body 21. The front end plate 22 is parallel to the connecting plate 12. The front end plate 22 has a forward-protruding front boss 23 corresponding to the positioning protrusions 13. The boss 23 surrounds the outside of the positioning boss 13 and is clearance-fitted with the positioning boss 13. Specifically, the inner side of the front boss 23 is an arc-shaped surface that conforms to the outer side of the positioning boss 13. The end of the front boss 23 near the front end plate 22 is provided with a front protruding boss 24. The front protruding boss 24 is located outside the front boss 23 and is fixedly connected to the front boss 23. The front boss 23 and the front protruding boss 24 are integrally formed, and the front protrusion length of the front boss 23 is greater than the front protrusion length of the front protrusion of the front protruding boss 24. The outer dimensions of the positioning boss 13, the front boss 23, and the front protruding boss 24 are from small to large, corresponding to three types of mounting holes respectively. The spring 3 is connected to the bracket 2 and is used to drive the bracket 2 to move axially along the mounting hole on the server rack column 20, so that the bracket 2 and the bracket 1 can be slidably connected.

[0020] Among them, such as Figure 1-3 As shown, the front end of the positioning protrusion 13 is tapered, and the exposed corners of the front protrusion 23 and the front protrusion 24 are rounded to ensure that the column will not be damaged and to facilitate the docking of the positioning protrusion 13, the front protrusion 23 and the front protrusion 24 with the mounting hole.

[0021] like Figure 1 , 3As shown, the second front boss 24 is used for contour positioning of the square mounting hole, including a horizontal side 241 and at least one vertical short side 242 perpendicularly disposed at the end of the horizontal side 241. In this embodiment, the second front boss 24 includes a horizontal side 241 and two vertical short sides 242 disposed at both ends of the horizontal side 241, which is a "U" shaped structure, but is not limited to this. It can also be a right-angled structure, including a horizontal side and a vertical short side perpendicularly disposed at the end of the horizontal side, as long as it can accommodate the mounting hole for positioning the square.

[0022] like Figure 1 , 3 As shown, the rear end of the front plate 22 is provided with a protruding spring connecting part 25, and the rear end of the bracket body 11 is provided with a protruding spring connecting part 24. The two ends of the spring 3 are respectively connected to the spring connecting part 25 and the spring connecting part 24. When an external force is applied to the front boss 23 or the front boss 24, the spring 3 is extended or retracted, thereby causing the bracket 22 to move axially along the mounting hole.

[0023] In this embodiment, the spring 3 is a square spring, and the bracket body 11 is provided with a square receiving groove 15 to accommodate the spring 3. The installation space of the square spring is small, which can avoid the installation of the cabinet screw in the middle of the front plate 22, and the screw installation position is close to the spring connection part 25.

[0024] like Figure 1 , 3 As shown, the second bracket body 21 is provided with at least one guide groove 26. Specifically, the second bracket body 21 is provided with two guide grooves 26, located on both sides of the spring 3. The slide rail 10 is provided with guide limiting members 4 corresponding to the guide grooves 26. The guide limiting members 4 protrude from the outside of the slide rail 10, and at least a part of the guide limiting members 4 is placed in the guide grooves 26. The guide limiting members 4 and the guide grooves 26 cooperate to guide and limit the movement of the second bracket 2, so that the mounting holes of the positioning protrusion 13, the first front protrusion 23 and the second front protrusion 24 are accurately aligned. In this embodiment, the guide limiting member 4 is a rivet. One end of the rivet is fixed to the slide rail 10, and the other end passes through the third bracket 6, the first bracket 1, and the second bracket 2 in sequence. The rivet head at this end is placed in the guide groove 26 to guide and limit the movement of the second bracket.

[0025] like Figure 1-3 As shown, the end connection structure of the slide rail also includes a cabinet lock 5. The front end of the cabinet lock 5 is provided with a locking part 51, which is located on the front side of the connecting plate 12 and is used to pressure lock the column 20. After the positioning protrusion 13, the first front protrusion 23 or the second front protrusion 24 are positioned with the mounting hole of the column 20, the front side of the column 20 is then pressure locked by the locking part 51 to ensure that the slide rail is installed firmly.

[0026] Specifically, a bracket 3 6 is provided between bracket 1 and slide rail 10 and is fixedly connected to slide rail 10. That is, bracket 3 6, bracket 1 1 and bracket 2 are arranged in sequence along the direction away from slide rail 10. Bracket 3 6 has a through installation notch 61, and slide rail 10 also has a corresponding through groove. The rear end of cabinet lock 5 is a pivot part 52, which passes through the installation notch 61 and is pivotally connected to bracket 3 6.

[0027] like Figure 1-2 As shown, the pivot part 52 includes two pivot ears 521, and two pivot ears 62 protruding from the main body of the bracket 6 are provided on both sides of the mounting notch 61. The pivot ears 521 and the pivot ears 62 are connected by a pin 8.

[0028] like Figure 1-3 As shown, a tension spring 7 is also provided between the pivot 52 and the bracket 6. In the locked state, the tension spring 7 applies pressure to the locking part 51.

[0029] The front end of bracket 3 6 extends to the front end of bracket body 11 and is stacked on the inner side of bracket 11. Specifically, the front end of bracket 3 5 is fixedly connected to bracket 11 and slide rail 10 by a set of rivets. Bracket 11 and bracket 2 are stacked on the front end of bracket 3, which improves the strength of bracket 3 and the entire connection structure, thereby ensuring the connection strength of cabinet lock pivot 52 and the locking strength of cabinet lock 5 against column 20. The rear end of bracket 3 6 is also fixedly connected to slide rail by a set of rivets, which is simple and convenient to install. The rear end of bracket 3 6 is provided with a tension spring connecting part 1 63 protruding outward. The pivot 52 is provided with a tension spring connecting part 2 53 located between two pivot lugs 1 521. The two ends of tension spring 7 are respectively connected to tension spring connecting part 1 63 and tension spring connecting part 2 53. The second tension spring connector 53 also protrudes outward, and its protruding length is greater than that of the first tension spring connector 63. The tension spring 7 is axially inclined relative to the third bracket 6, so that in the locked state, the tension spring 7 acts on the locking part 51 to apply a continuous locking and clamping force to the column 20, ensuring a stable connection. The second tension spring connector 53 is provided with a bayonet groove for connecting with the tension spring 7, as well as a boss and end flange to improve strength, ensuring the strength of the second tension spring connector 53 and its connection strength with the tension spring 7, thereby ensuring a continuous locking and clamping force.

[0030] In addition, such as Figure 1 , 2 As shown, the pivot part 52 of the cabinet lock 5 is connected to the locking part 51 by an extension plate 54. The pivot lug 521 is inclined to the extension plate 54. The inner side of the outer rail of the slide rail 10 is provided with a groove that matches the extension plate 54, which limits the position of the locking part.

[0031] The working principle is as follows: the three common mounting holes on the server rack column have external dimensions in ascending order as threaded hole, round hole, and square hole.

[0032] like Figure 4 As shown, for the mounting holes of the cabinet columns with threaded holes, after the front end of the slide rail is connected to the end of the assembly, the positioning protrusion 13 on the bracket 1 is inserted into the corresponding threaded hole. At the same time, the front protrusion 23 of the bracket 2 is pressed backward by the column 20 stop, the spring 3 is compressed, the bracket 2 moves to the rear end, and then the cabinet lock 5 is flipped so that the locking part 51 locks and presses against the column 20. Its locking and pressing force is maintained by the tension spring.

[0033] like Figure 5 As shown, for the mounting holes of the cabinet columns with round holes, after the front end of the slide rail is connected to the end of the assembly, the positioning protrusion 13 on the bracket 1 is inserted into the corresponding round hole. At the same time, the position of the bracket 2 is adjusted so that the front protrusion 23 of the bracket 2 is also inserted into the round hole under the action of the spring 3. The front protrusion 24 is stopped by the column 20 and elastically abuts against the column 20. Then, the cabinet lock 5 is flipped so that the locking part 51 locks and presses against the column 20. Its locking and pressing force is maintained by the tension spring.

[0034] like Figure 6 As shown, for the cabinet column with square holes, after the front end of the slide rail is connected to the end of the assembly, the positioning protrusion 13 on bracket one and the front protrusion 23 on bracket two are inserted into the corresponding square holes. At the same time, the position of bracket two 2 is adjusted so that the front protrusion 24 is fully inserted into the corresponding side area of ​​the square hole under the pushing force of the spring, thus completing the quick positioning with the square hole. Then, the cabinet lock 5 is flipped so that the locking part 51 locks and presses against the column 20, and its locking and pressing force is maintained by the tension spring.

[0035] In summary, this utility model is compatible with the quick alignment and installation of three types of column mounting holes, has good versatility, and has a simple structure, is easy to assemble, and is stable to install.
