elongated holes

341 and 342.

The elastic locking piece 20 comprises a locking piece 21, a pin shaft 22 and a tension spring 23, wherein the locking piece 21 is rotatably arranged on the mounting plane 11 of the rear bracket 10 through the pin shaft 22; the locking piece 21 comprises a rotary connecting part 211 and a locking part 213, the rear end of the locking part 213 is bent downwards to form a downward hook 214, the hook end penetrates through

elongated holes

341 and 342 on the front side wall and the rear side wall of the positioning bracket 31 of the positioning assembly from front to back and then extends out of the rear end surface of the positioning bracket 31, the length of the

elongated holes

341 and 342 is greater than the width of the locking part 213 of the locking piece, and the

elongated holes

341 and 342 can be any one of rectangular holes and long waist holes; referring to fig. 7, the front end surface of the hook 214 of the locking tab 21 is a hooking surface 2143 that locks with the server rack 50, the rear end surface is an inclined surface 2141 that inclines downward toward the front, the inclined surface 2141 and the hooking surface 2143 are connected into a whole by a horizontal connection surface 2142, and the inclined surface 2141 and the horizontal connection surface 2142 are transitionally connected by an arc surface 2144; the rotary connecting part 211 is rotatably mounted on the mounting plane 11 of the rear bracket 10 through a pin 22, so that when the locking piece 21 rotates around the pin 22, the locking piece can swing in the elongated holes 34 of the front and rear side walls of the positioning bracket 31; the connecting part 211 and the locking part 213 are connected into a zigzag integral structure through the transitional connecting part 212, a through hole 215 is formed in the transitional connecting part 212, and one end of the tension spring 23 penetrates through the through hole 215 and is hooked with the transitional connecting part 211 so as to provide a pretightening force to the tension spring; the tension spring 23 is sleeved on the pin shaft 22, and one end of the tension spring 23 passes through the through hole 215 and then is bent to be hooked with the transition connecting part 212; the side wall of the rear bracket 10 is provided with a bayonet groove 13, the movable connecting end of the tension spring 23 is bent to form a hook-shaped end 231, and the hook-shaped end 231 is clamped in the bayonet groove 13.

The rear end tool-free mounting bracket realizes locking between the locking piece 21 and the server cabinet through the elastic force of the tension spring 23; in the locked state, the locking piece 21 is in an inclined state with a lower back and a higher front under the action of the pretightening force of the tension spring 23, and the hook-shaped end 231 of the tension spring 23 is in a free tilting state; when the rear end of the slide rail 50 is installed on the server cabinet through the rear end tool-free installation bracket of the invention, the two guide sleeves 34 of the positioning assembly 30 of the rear end installation bracket are aligned with the

installation positioning holes

51 and 53 of the server cabinet, meanwhile, the hook 214 at the rear end of the locking piece 21 extends into the installation hole 52 at the rear end of the server cabinet, the locking piece 21 is inclined with a lower back and a higher front due to the pre-tightening force of the tension spring 23, so the rear end inclined plane 2141 of the hook 214 abuts against the lower edge of the installation hole 52 at the rear end of the server cabinet, the hook 214 is synchronously inserted into the installation hole 52 in the process of inserting the two guide sleeves 34 into the

installation positioning holes

51 and 53, and in the inserting process, the lower edge of the installation hole 52 always abuts against the rear end inclined plane 2141 to push the locking piece 21 to overcome the pre-tightening force of the tension spring 23 to rotate clockwise around the pin 22, and the tension spring 23 fastened to the pin 22 also synchronously rotates clockwise until the hook 214 moves to the horizontal connection plane 2142 to abut against the lower edge of the installation hole 52, Therefore, the hooked end 231 of the tension spring 23 is completely hooked with the bayonet groove 13 of the rear bracket 10, at this time, the locking piece 21 is in a horizontal state, the sliding rail 40 is continuously pushed backwards until the horizontal connecting surface 2142 of the locking piece 214 is separated from the lower edge of the mounting hole 52, at this time, the locking piece 214 of the locking piece 21 is free from the lower edge of the mounting hole 52 and is abutted against and bound, and is subjected to the action of the pre-tightening force of the tension spring 23 again to rotate anticlockwise around the pin shaft 22, the tension spring 23 fastened to the pin shaft 22 is also pulled anticlockwise synchronously until the locking piece 21 is restored to be in a low-front-high inclined state, so that the hooking surface 2143 of the locking piece 214 is hooked with the rear end surface of the mounting hole 52 of the server cabinet and locked, as shown in fig. 8.

The transitional coupling portion 212 of the locking piece 20 can be smoothly connected and transited with the locking portion 213 and the rotation coupling portion 211.

The rear bracket 10 is provided with a convex hull 12 on the mounting plane 11, as shown in fig. 3, 4, 5 and 6, the rotary connecting part 211 of the locking piece 20 is rotatably mounted on the convex hull 12 through a pin 22; because the contact area of the convex hull 12 and the rotary connecting part 211 of the locking piece 20 is small, the relative friction force is small, namely the friction force between the upper locking piece 20 and the rotary connecting part can be effectively reduced when the upper locking piece 20 rotates, the reliable rotation of the locking piece 20 is ensured, and the reliable work of the whole elastic locking piece 20 is ensured.

The bayonet grooves 13 are formed in the two side walls of the rear support 10 respectively, the rear support 10 can be adjusted and installed on the front side and the back side according to the actual installation direction or the actual installation position of the server cabinet slide rail 50, meanwhile, the installation direction and the installation position of the locking piece 21 and the tension spring 23 can be adjusted along with the actual installation direction or the actual installation position of the rear support 10, and the applicability of the rear support 10 is improved.

The locking part 213 of the locking piece 20 is set to be tapered from front to back in width, see fig. 7, so that the locking piece 20 can further reliably swing on the elongated hole 34 on the front and back side walls of the positioning bracket 31, and the locking with the server cabinet is ensured to be reliable.
