For convenience of description, the end of the first sliding rail 100 near the user is defined as a first end a 131, and the end far from the user is defined as a second end a 132; the second sliding rail 200 has a first end B231 near the user and a second end B232 far from the user. The first end a 131 is provided with a fixed shaft 110; the second end B232 is provided with a hook portion 210, and the hook portion 210 has a limiting groove 212. The second sliding rail 200 has a first position, a second position and a third position relative to the first sliding rail 100; when the second slide rail 200 is at the first position, the fixing shaft 110 is separated from the hook 210, and the second end B232 is closer to the second end a 132 than the first end B132, referring to fig. 1 and 2; when the second sliding rail 200 is at the second position, the fixed shaft 110 slides into the hook 210, referring to fig. 3; when the second slide rail 200 is at the third position, the fixed shaft 110 is locked in the limit groove 212, and the second slide rail 200 is inclined relative to the first slide rail 100, see fig. 4.

In fig. 1 to 4, in order to clearly express the state change of the entire slide rail mechanism when the second slide rail 200 is at each position, the second slide rail 200 is structurally expressed from two viewpoints in each position state, respectively. Fig. 1 (a), 2 (a), 3 (a) and 4 (a) are perspective views, fig. 1 (b), 2 (b), 3 (b) and 4 (b) are front views, and fig. 1 (b), 2 (b), 3 (b) and 4 (b) are perspective views for clearly expressing the fitting relationship among the fixing shaft 110, the hook portion 210 and the limiting groove 212.

When the second slide rail 200 is at the first position, the second slide rail 200 can slide reciprocally along the first slide rail 100. Fig. 1 is a schematic structural diagram of the second sliding rail 200 when it has not been pulled outwards relative to the first sliding rail 100, where the first end a 131 coincides with the first end B231, and the second end a 132 coincides with the second end B232. Fig. 2 is a schematic structural diagram of the second sliding rail 200 after being pulled out a distance with respect to the first sliding rail 100, in which the second end B232 gradually moves toward the first end a 131 along with the outward pulling of the second sliding rail 200.

When the second slide rail 200 is pulled to the second position, referring to fig. 3 and 5, the fixing shaft 110 slides into the hook 210, and the second slide rail 200 cannot slide forward.

The second slide rail 200 is pressed downwards, the second slide rail 200 is inclined downwards relative to the first slide rail 100, and referring to fig. 4 and 7, at this time, the hook portion 210 rotates clockwise around the fixed shaft 110, and the fixed shaft 110 is locked into the limit groove 212 in a clockwise direction, so that the second slide rail 200 is inclined downwards and does not fall. In addition, the second sliding rail 200 further makes the clamping between the fixing shaft 110 and the limiting groove 212 more reliable and not easy to fall off under the action of gravity.

As a preferred embodiment, the hook portion 210 includes a main body 211, a limiting groove 212 is formed on the main body 211, and an opening 213 of the limiting groove 212 faces upward, so that the fixing shaft 110 can be smoothly clamped into the limiting groove 212 when the second sliding rail 200 is inclined downward.

Further preferably, referring to fig. 5 and 7, the main body 211 is provided with an upper blocking portion 214, the upper blocking portion 214 is a baffle structure integrally formed with the main body 211, and the upper blocking portion 214 is opposite to the limit groove 212. The upper blocking portion 214 plays a certain guiding role, so that the fixing shaft 110 can slide into the hook portion 210. Meanwhile, in the movement process that the second sliding rail 200 is inclined downwards and is not clamped in the limiting groove 212, the upper blocking portion 214 can also prevent the fixing shaft 110 from being separated from the clamping hook portion 210, so that the whole sliding rail structure is more reliable.

Of course, in other embodiments, the hook portion 210 may not be provided with the upper stop portion 214, and the second slide rail 200 can also perform the tilting motion.

As a preferred embodiment, referring to fig. 8, the first slide rail 100 includes a side plate a 140, an upper plate a 150 disposed on an upper side of the side plate a 140, and a lower plate a 160 disposed on a lower side of the side plate a 140, and the fixed shaft 110 is disposed on the side plate a 140. Referring to fig. 9, the second slide rail 200 includes a side plate B240 and an upper plate B250 disposed above the side plate B240, and the hook portion 210 is disposed on the side plate B240. When the second slide rail 200 is at the first position, the upper plate B240 is located inside the upper plate a 250, and the side plate B240 is opposite to the side plate a 140. That is, the first sliding rail 100 and the second sliding rail 200 are buckled, the second sliding rail 200 is located at the inner side of the first sliding rail 100, and a cavity is formed between the two, so that the fixed shaft 110, the hook portion 210 and the limiting groove 212 can move cooperatively, and the thickness dimension and the occupied space of the whole sliding rail mechanism can be reduced.

As a preferred embodiment, the first slide rail 100 further includes a front side plate a 170 at the first end a 131 and a rear side plate a 180 at the second end a 132; the second slide rail 200 further includes a front side plate B260 at the first end B231 and a rear side plate B270 at the second end B232. The front side plate A170, the rear side plate A180, the front side plate B260 and the rear side plate B270 play a role in shielding the inner space defined by the first sliding rail 100 and the second sliding rail 200 together, so that the whole sliding rail mechanism is more attractive.

As a preferred embodiment, the relative sliding between the first sliding rail 100 and the second sliding rail 200 is realized by a roller structure, so that the friction force is small and the noise is low. Specifically, the free end of the fixed shaft 110 is provided with a first roller 120, and the first roller 120 is in rolling contact with the inner side of the second slide rail 200. The second sliding rail 200 is provided with a second roller 220, the hook portion 210 is connected with the second roller 220, and the second roller 220 is in rolling fit with the inner side of the first sliding rail 100. When the first slide rail 100 and the second slide rail 200 slide relatively, the first roller 120 and the second roller 220 will both rotate.

As a preferred embodiment, referring to fig. 1 (B), the first roller 120 is in rolling contact with the upper inner side surface of the second slide rail 200, that is, the first roller 120 is in rolling contact with the upper plate B250; the second roller 220 is in rolling contact with the inner side surface of the lower portion of the first slide rail 100, that is, the second roller 220 is in rolling contact with the lower plate a 160. When the first rail 100 and the second rail 200 slide relatively, the first roller 120 will roll along the upper plate B250 and the second roller 220 will roll along the lower plate a 160. As can be seen from fig. 1 (b), the first roller 120 and the second roller 200 are disposed in a relatively staggered manner, so that when the first sliding rail 100 and the second sliding rail 200 slide relatively, no vertical shaking occurs between them, and the whole sliding rail mechanism is more stable.

Further, a certain gap is formed between the side plate B240 and the lower plate a 160, and a certain gap is also formed between the upper plate a 150 and the upper plate B250, so that when the first slide rail 100 and the second slide rail 200 slide relatively, only the rolling between the first roller 120 and the upper plate B250, and between the second roller 220 and the lower plate a 160 is realized, and the rest parts of the first slide rail 100 and the second slide rail 200 are not contacted, which is beneficial to reducing friction and noise.

As a preferred embodiment, the first roller 120 and the second roller 220 roll and fit when the second slide rail 200 is switched between the second position and the third position. Specifically, when the second slide rail 200 is located at the second position, referring to fig. 5, the first roller 120 and the second roller 220 are attached. When the second sliding rail 200 is changed from the second position to the third position, the second sliding rail 200 is pressed downwards, and the second roller 220 will roll clockwise along the first roller 120, referring to fig. 7, so that the downward tilting movement of the second sliding rail 200 is smoother. Similarly, when the second rail 200 is moved from the third position to the second position, the second rail 200 is lifted upward, and the second roller 220 will roll counterclockwise along the first roller 120 until it contacts the lower plate a 160.

As a preferred embodiment, the upper plate a 150 has a notch 151, the notch 151 being located at the first end a 131. When the second slide rail 200 is in the third position, referring to fig. 6, the second end B232 extends from the notch 151, and the notch 151 is configured to yield for the second end B232, so as to facilitate the downward tilting of the second slide rail 200.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
