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
[0004] In addition, in order to ensure the stability and synchronization of the sliding mechanism of the slide rail mechanism, it is necessary to ensure that the tension parts located on the side of the upper rail and the middle rail in the synchronous structure are in a tight state. Currently, the adjustment of the tension parts is inconvenient, which affects the user experience

Embodiment approach
[0068] 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 synchronization 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 cooper...

A slide rail mechanism (100) and a refrigerator having same. Each slide rail assembly (1) comprises an upper rail (11), a middle rail (12), and a lower rail (13). The slide rail mechanism (100) further comprises a synchronization mechanism (2) which comprises two auxiliary middle rail assemblies (5), steering members (21) provided on the auxiliary middle rail assemblies (5), tensioning member (23), and fixing members (22) provided on the two slide rail assemblies (1). The tensioning member (23) is wounded between the fixing members (22) of each of the two slide rail assemblies (1) by means of the steering members (21). The synchronization mechanism (2) further comprises a tensioning sleeve (24). At least one of two rear steering members (212) is provided with an adjusting assembly (4), which is movably connected to the tensioning sleeve (24). The tensioning sleeve (24) drives the tensioning member (23) to move away from the adjusting assembly (4) until the length of the tensioning member (23) between the two rear steering members (212) is greater than the distance between the two rear steering members (212). By adding the auxiliary middle rail assemblies (5) and providing the steering members (21) on the auxiliary middle rail assemblies (5), changes in gaps between the upper rails (11) and the lower rails (13) do not affect the steering members (21); the tightness degree of the parts of tensioning member (23) outside the tensioning sleeve (24) can be adjusted by the adjusting assembly (4), so that the parts of tensioning member (23) outside the tensioning sleeve (24) is kept in a tensioned state all the time.
