Detailed ways

A two-section server slide rail as shown in Figure 1, which includes a front-end mounting bracket 1, a rear-end mounting bracket 2, and a two-section track 3, combined with Figures 2, 3, and 7, the two-section track 3 Including the inner rail 31, the outer rail 32, and the ball cage 33 between the inner rail 31 and the outer rail 32; There is a locking structure, and the locking structure includes locking piece 1 311, locking piece 2 312 and torsion spring 313; the rear end of locking piece 1 311 is connected with the inner rail 31 by pin rotation, and the bottom of locking piece 1 311 is provided with a lock that cooperates with the locking block 321 Groove 3111, the front and rear walls of the lock groove 3111 are vertical or inclined to the inside of the lock groove. This design can ensure that the lock block is limited in the lock groove and cannot be disengaged even if it is subjected to lateral tension; the bottom of the lock piece 311 is located in front of the lock groove 3111 Also be provided with guiding and avoiding surface 3112, guiding and avoiding surface 3112 is inclined plane or circular arc surface, if like this makes lock block and guide avoiding surface contact, if continue to be subjected to transverse force can produce upward component force to locking plate one 311 and make it rotate upwards Avoid the lock block. When the slide rail is opened and the lock block 321 is not in contact with the lock piece 1 311, the lock piece 321 is located on the moving path of the guide avoidance surface 3112 and the lock groove 3111. With reference to Figure 4 and Figure 5, the lock piece 1 The front end of 311 is connected with vertical limiting groove 1 315 on the inner rail 31 by connecting pin 1 314 and the oblique limiting groove 2 3121 on locking piece 2 312, and the front end of locking piece 1 311 is also connected with inner rail 31 by torsion spring 313 Connection; the second locking piece 312 includes a second limiting groove 3121 at the rear, an elongated portion 3122 at the middle, and an unlocking portion 3123 at the front. The second locking piece 312 is slidably connected with the inner rail 31 . Specifically, the unlocking part 3123 includes a connecting block 3124, an unlocking block 3125, and a second connecting pin 3126. The rail 31 is connected, and the unlocking block 3125 is slidably installed on the inner rail 31 through the sliding groove 3127 and the connecting pin 2 3126.

When in use, pump the chassis and drive the inner rail 31 to open, and the inner rail 31 moves forward with the locking structure. The guiding and avoiding surface 3112 of the locking piece 1 311 first touches the locking block 321. Since the guiding and avoiding surface 3112 is an inclined plane or an arc surface Under the action of the lock block 321, the lock piece 311 rotates upward to avoid the lock block 321, and the inner rail continues to move until the lock piece 321 reaches the bottom of the lock groove 3111. The lock piece 311 falls, and the lock piece 321 enters the lock groove, and the lock groove The front and rear walls of 3111 are in a vertical state or inclined to the inside of the lock groove, so that no matter whether the lock block is in contact with the front wall or the rear wall, the lock plate cannot be rotated, thereby restricting the continued movement or retreat of the inner rail; when needed When unlocking, move the unlocking block 3125 forward with your fingers, and under the action of the oblique limiting groove 2 3121, the locking piece 1 311 rotates upwards. At this time, pushing the inner rail inward can make the locking block 321 withdraw from the locking groove, realizing unlock.

In addition, with reference to Fig. 2, Fig. 3 and Fig. 6, the chassis installation structure is also included.
