Problems solved by technology
[0002] At present, the three-section slide rails on the market mainly have the following problems in practical application: First, noise is generated during use: the existing three-section slide rails use the upper rail to run first, and when the upper rail travel distance reaches the extreme, use the upper rail Contact and collide with the limit device of the middle rail, and pull out the middle rail; also use the limit device of the middle rail and the lower rail to contact and collide, to reach the distance that the middle rail is pulled to reach the pole; and the limit device is between the upper rail and the middle rail , The noise of "peddling, pedaling" is generated during the contact and collision between the middle rail and the lower rail, which brings high-frequency noise to the user
In practical application, with the increase in the number of times the three-section slide rail is used, the internal steel balls and the upper rail, lower rail, and middle rail are prone to wear, resulting in a gradual decrease in the gap distance between the upper rail and the lower rail. The distance between the rail and the base connection is extremely small. At this time, the reduction of the gap distance is likely to cause interference between the upper rail and / or the lower rail and the base connection, or even jamming
Therefore, there is a problem in the reliability of the three-section slide rail in the prior art

Embodiment approach
[0067] Here, on the basis of the three-section slide rail in the prior art, the auxiliary middle rail assembly 5b is added, and the steering piece 21 of the synchronous mechanism 2 is arranged on the auxiliary middle rail assembly 5b, and the steering piece 21 and the three-section slide rail are not connected to each other. Contact, that is to say, at this time, the moving tracks of the steering member 21 and the tension member 23 do not overlap with the sliding tracks of the three-section slide rails, even if the gap between the upper rail 11 and the lower rail 13 is reduced due to wear, it does not overlap. It will affect the normal operation of the steering member 21 in the synchronous mechanism 2, and can effectively solve the problem of interference between the steering member 21 and the upper rail 11 and / or the lower rail 13 in the prior art. In addition, this embodiment can utilize the common three-section slide rail structure in the market, and only needs to cooperate ...

The invention discloses a slide rail mechanism and a refrigerator comprising the same. The slide rail mechanism is used for pulling a drawer out of a refrigerator body or pushing the drawer into the refrigerator body. Each slide rail assembly comprises an upper rail, a middle rail and a lower rail. The slide rail mechanism further comprises a synchronizing mechanism body for enabling the first slide rail assembly and the second slide rail assembly to move synchronously. The synchronizing mechanism body comprises two auxiliary middle rail assemblies, steering pieces, tensioning pieces and fixed pieces, wherein the two auxiliary middle rail assemblies are matched with the two slide rail assemblies; the steering pieces and the tensioning pieces are arranged on the auxiliary middle rail assemblies; and the fixed pieces are arranged on the two slide rail assemblies. The tensioning pieces are arranged between the fixed pieces of the two slide rail assemblies through the steering pieces in a winding mode, so that the tensioning pieces drive the upper rail or the middle rail of the second slide rail assembly to displace by the same distance in the same direction through the fixed pieces when the upper rail or the middle rail of the first slide rail assembly moves. According to the slide rail mechanism and the refrigerator comprising the same, the auxiliary middle rail assemblies are additionally arranged, and the steering pieces are arranged on the auxiliary middle rail assemblies so that normal operation of the steering pieces cannot be influenced by the change of clearances between the upper rails and the lower rails, and accordingly the stability of the synchronizing mechanism body is ensured.
