During the rotation, the hook 223 can extend into the second escape hole 216 on the main body 211, and the hook 223 The first inclined surface 2236 contacts the second inclined surface 232 of the buckle limiting structure 23, and rotates the above-mentioned rotating buckle bracket 22 under the action of external force. The thrust of the hook 223 acts on the second inclined surface 232 to produce a split parallel to the main body 211. The force drives the buckle limiting structure 23 to translate relative to the main body 211. The translation of the buckle limiting structure 23 causes the elastic member 28 to be elastically deformed by the tensile force, and stores elastic potential energy.

13 and 14, the rotating buckle bracket 22 is further rotated so that the hook portion 2234 passes through the buckle hole 231, and the action of the elastic potential energy causes the elastic member 28 to automatically reset, thereby driving the buckle limiting structure 23 to return. , The locking surface 2235 of the hook portion 2234 is in contact with the reverse surface of the buckle limiting structure 23 to achieve self-locking. The enlarged view of FIG. 18 can clearly see the locking surface 2235 of the hook portion 2234 and the buckle limiting structure 23 The surface of the bracket forms a locking and fitting structure, and the buckle limiting structure 23 blocks the hook portion 2234, so that the hook portion 2234 is firmly locked in the buckle hole 231. At the same time, the stopping portion 222 is also rotated to the outside of the upright column 104, and the stopping portion 222 is accommodated in a position between the pair of positioning columns 24. In the locked state, the stopper 222 is located on the side of the end 212 of the rail 21 away from the main body 211, and the stopper 222 and the end 212 are used to accommodate the upright 104 of the cabinet.

When the sliding rail 20 needs to be removed from the column 104, an external force is required to drive the hook 223 out of the buckle hole 231. In a possible implementation manner, unlocking is performed by the unlocking part 26. 15 and 16, the unlocking portion 26 is moved so that the buckle limiting structure 23 is translated toward the end 212 of the main body 21. The position of the unlocking portion 26 expressed by the dotted line in FIG. 15 is the position of the unlocking portion 26 in the locked state , That is, the position before the unlocking part is not moved. After the position of the unlocking part 26 is moved, the unlocking part 26 is moved to the position of the unlocking part 26 represented by the solid line in FIG. 15. Similarly, the dotted line in 16 expresses the position of the buckle limit structure 23 in the locked state. When the unlocking portion 26 is moved, the buckle limit structure 23 moves simultaneously. The position expressed by the solid line in Figure 16 is the buckle The position of the limit structure 23 after movement. It can be seen that the position of the buckle hole 231 also moves, but the position of the hook 223 remains unchanged, so that the locking surface 2235 of the hook 223 is separated from the buckle limiting structure 23, and the hook portion 2234 of the hook 223 is completely connected to the hook 223. The inner space of the buckle hole 231 corresponds, as shown in FIG. 17, in this state, the locked state is released, and the hook 223 can be moved out of the buckle hole 231 by rotating the rotating buckle bracket 22.

In a possible implementation, the unlocking member 26 has both unlocking and sliding connection and positioning functions. In the embodiment shown in FIGS. 3 and 4, the sliding rail includes the connection between the unlocking member 26 and the mounting hole 217 to form a sliding connection between the buckle limiting structure 23 and the main body 211, and also includes the rivet 27 sliding connection structure.

Optionally, the rivet 27 may not be provided in the above sliding connection structure, and only the unlocking piece 26 is used to realize the sliding connection, so that the unlocking piece 26 has a dual function, eliminating other sliding connection structures, and is conducive to a simpler structure of the slide rail design.

It can be seen from FIG. 13 that the unlocking portion 26 is located on the side of the rotating buckle bracket 22 away from the blocking portion 222. The rotary buckle bracket 22 is provided with a hollow area 227, which is arranged at the edge of the mounting portion 221 away from the stop portion 22, and the hollow area 227 extends between the two adapter portions 224, so that the unlocking portion 26 can be located between the two transition parts 224, which has the advantage of saving space.

In a possible implementation, the unlocking structure is not limited to the structure of the unlocking portion 26, and the locked state can also be released in other ways. As long as the structure that can drive the buckle limiting structure 23 to move, the unlocking function can be realized.

In a possible implementation, a torsion spring is provided at the rotational connection between the adapter portion 224 of the rotary buckle bracket 22 and the main body 21, and in the locked state, the torsion spring is in an elastic compression state. When the unlocking portion 26 is moved to release the locked state, under the action of the torsion spring, the rotating buckle bracket 22 is automatically opened. The torsion spring can not only automatically spring the rotating buckle bracket 22 in the unlocked state, but in the locked state, due to the elastic tension of the torsion spring, the locking surface 2235 of the hook 223 can be closely attached to the surface of the buckle limiting structure 23 , To ensure that the position of the rotating buckle bracket 22 is stable and not loose, and it can also ensure that no much noise is generated during the working process of the server.

In another possible implementation manner, an elastic resisting member may also be provided between the mounting portion 221 of the rotary buckle bracket 22 and the main body 211. In the locked state, the elastic resisting member is in an elastic compression state. When unlocked, The elastic resisting member bounces the mounting part open, so as to realize the automatic opening of the rotating buckle bracket 22. The elastic resisting member can be fixedly connected to the main body 211, and can be an elastic piece fixed on the surface of the main body 211. The elastic piece can be arched. In a natural state, the elastic piece protrudes from the surface of the main body 211, and the mounting part is pressed against the elastic piece. , So that the elastic deformation of the shrapnel.

In the above embodiment, the first inclined surface 2236 and the second inclined surface 232 cooperate, so that the thrust of the hook 223 acting on the second inclined surface 232 generates a component force parallel to the main body 211. The first inclined surface 2236 and the second inclined surface 232 may have only one feature. For example, only the hook portion 2234 is provided with a first inclined surface 2235, and the buckle limiting structure 23 is not provided with an inclined surface. The first inclined surface 2235 and the edge of the buckle hole 231 The line contact between them can also generate a component force parallel to the main body. Similarly, the hook portion 2234 has no inclined surface feature, and this principle can be realized by only retaining the second inclined surface 232 feature. The first inclined surface 2236 and the second inclined surface 232 exist at the same time, and the switching from rotation to translation is realized through surface contact, which can ensure the stability of the mating structure of the hook portion 2234 and the buckle limiting structure 23.

The rotating buckle bracket 22 is a sheet metal structure, and in a possible implementation manner, the material can be stainless steel. The buckle limiting structure 23 is a sheet metal structure. In one embodiment, the material may be die-cast zinc. The hardness of the buckle limiting structure 23 is less than the hardness of the rotary buckle bracket 22, because the rotary buckle bracket 22 is provided on one side of the inner surface of the main body 211 of the rail 21, and needs to be matched with the server, which requires stronger rigidity. The limiting structure 23 is located on the outer surface of the main body 211 of the rail 21, and is only used to fix the rotating buckle bracket 22, and does not require strong hardness. Therefore, the present application selects different materials for the components of the slide rail according to specific needs. Reasonably optimize the cost of slide rails.

In the present application, the rotating buckle bracket 22 is rotatably connected to the main body 211, the buckle limiting structure 23 is slidably connected to the main body 211, and the hook 223 of the rotating buckle bracket 22 is matched with the buckle hole 231 of the buckle limiting structure 23 The rotating buckle bracket 22 can be used to rotate the buckle limiting structure 23 to translate, and under the action of the elastic force of the elastic member, the hook 223 and the buckle hole 231 can be locked. When installing the slide rail 20 to the column 104 in the cabinet, no tools are needed. Just position the positioning column 24 on the slide rail 20 in the positioning hole 1042 on the column 104 for pre-positioning, and then manually rotate the rotating card By buckling the bracket 22, the installation of the slide rail 20 can be completed and the locked state is formed, so that the slide rail 20 is reliably fixed in the cabinet.
