[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 6 A slide rail locking structure, comprising a positioning member 3 mounted on a fixed slide rail 1 and a locking mechanism 4 mounted on a movable slide rail 2, wherein the locking mechanism 4 comprises a mounting seat 41 which moves synchronously with the movable slide rail 2, wherein the mounting seat 41 is provided with a locking element 43 which can move relative to the mounting seat 41 and is plugged and matched with the positioning member 3, wherein an elastic element 47 is provided between the locking element 43 and the mounting seat 41, wherein the elastic element 47 applies a force to the locking element 43 so that the locking element 43 and the positioning member 3 are kept plugged and matched;

[0024] A driving member 42 is rotatably provided on the mounting seat 41, and a protrusion 46 is provided on the driving member 42. A track block 44 is provided on the locking element 43, and an end surface of the track block 44 facing the protrusion 46 is a spiral slope 45, and the protrusion 46 is in contact with the spiral slope 45.

[0025] The driving member 42 is connected to the synchronization shaft 5;

[0026] The driving member 42 is provided with a lever 40 .

[0027] The utility model directly drives the driving member to rotate through the lever, and the driving member can drive the synchronous shaft to make the two locking structures synchronously drive. Compared with the prior art that uses rack and gear transmission to drive the synchronous shaft to rotate, the utility model has the advantages of simple structure, convenient processing and low manufacturing cost.

[0028] The utility model has a protrusion on the driving member and a track block on the locking element. The protrusion cooperates with the track block. Under the action of the driving member, the locking element can be driven to move toward a side away from the positioning member by pushing the track block to achieve the unlocking effect.

[0029] In the locked state, pulling the drawer 21 drives the slide rail 2 to move forward, and when the locking element 43 and the positioning member 3 coincide with each other, the elastic element 47 applies a force to the locking element 43 so that the locking element 43 and the positioning member 3 are plugged and locked.

[0030] See also Figure 2 The driving member 42 is a sleeve with a hollow interior and an opening disposed at one end toward the positioning member 3. The locking element 43 is movably disposed in the driving member 42. By disposing the locking element 43 in the driving member 42, the overall volume can be further reduced, making the overall structure more compact.

[0031] The elastic element 47 is disposed in the driving member 42 , and one end of the elastic element 47 is connected to the locking element 43 , and the other end of the elastic element 47 is connected to the driving member 42 .

[0032] See also Figure 2 and Figure 4 A limiting member 49 is provided on the end surface of the mounting seat 41 facing the positioning member 3, and the end surface of the locking element 43 facing the positioning member 3 is fitted and limited with the limiting member 49;

[0033] A guide plug-in portion 48 is provided on the end surface of the locking element 43 facing the positioning member 3 , and a guide hole 491 is provided on the limiting member 49 . The guide plug-in portion 48 is movably plugged into the guide hole 491 .

[0034] The function of the limiting member 49 is to constrain and limit the force of the elastic member 47 to prevent the locking member 43 from being separated from the driving member 42. At the same time, the plug-in cooperation between the guide plug-in portion and the guide hole can constrain the locking member 43 so that the locking member 43 can only move laterally relative to the mounting seat 41 but cannot rotate.

[0035] See also Figure 2 A guide column 421 is provided in the driving member 42 , and an inserting hole 431 is provided in the locking element 43 . The guide column 421 is movably inserted in the inserting hole 431 .

[0036] The elastic element 47 is a spring, and the elastic element 47 is sleeved on the guide post 421 .

[0037] See also Figure 2 and Figure 6 The positioning member 3 is provided with a positioning groove 31 , and the locking element 43 is plugged into and matched with the positioning groove 31 .
