As shown in fig. 1 to 8, an embodiment of the present invention provides a rack assembly, which includes an outer frame 1, a first rack 2 fixedly disposed in the outer frame 1, a second rack 3 movably disposed in the outer frame 1, and a slide rail assembly 4, wherein the slide rail assembly 4 includes an inner rail 41 and an outer rail 42 slidably disposed relative to each other, the inner rail 41 is fixedly connected to the outer frame 1, the outer rail 42 is movably connected to the second rack 3, when the rack assembly is in the folded state, the second rack 3 and the first rack 2 are overlapped with each other along the first direction, when the rack assembly is changed to the unfolded state, the outer rail 42 moves relative to the inner rail 41 to drive the second rack 3 to move away from the first rack 2, and when the second rack 3 and the first rack 2 are separated from each other, the second rack 3 moves relative to the outer rail 42 such that the second rack 3 moves in a first direction relative to the first rack 2.

Specifically, the rack assembly comprises an outer frame 1, a first rack 2, a second rack 3 and a slide rail assembly 4, wherein the slide rail assembly 4 comprises an inner rail 41 and an outer rail 42; the grooves of the inner rail 41 and the grooves of the outer rail 42 are staggered with each other, and the inner rail 41 and the outer rail 42 can slide relatively; the inner rail 41 is fixedly connected with the outer frame 1, the outer rail 42 is movably connected with the second rack 3, and the second rack 3 can vertically move relative to the outer rail 42.

Alternatively, the first rack 2 is fixedly coupled to the left upper half region of the outer frame 1, and the inner rail 41 is fixedly coupled to the left lower half region of the outer frame 1.

When the rack assembly is in the folded state, the second rack 3 is positioned in the lower area of the first rack 2 and is overlapped with the first rack 2; when the rack assembly is changed to the unfolded state, the outer rail 42 slides rightwards relative to the inner rail 41 to drive the second rack 3 to move rightwards away from the first rack 2; when the second rack 3 is completely separated from the first rack 2, the second rack 3 can be moved in a vertical direction relative to the outer rail 42 to generate a displacement until the second rack 3 and the first rack 2 reach a horizontal level, i.e. the rack assembly is completely unfolded.

It can be seen that, the slide rail assembly 4 is arranged in an internal and external staggered manner, the inner rail 41 is fixedly connected with the outer frame 1, the outer rail 42 is movably connected with the second rack 3, and the second rack 3 can horizontally move rightwards without being influenced by self gravity and incline downwards under the condition of no front side support through the relative sliding and mutual supporting action of the inner rail 41 and the outer rail 42; meanwhile, the second rack 3 can be horizontally aligned with the first rack 2 after moving up and down relative to the first rack 2, thereby achieving the effect that the rack assembly can be folded or unfolded left and right.

Preferably, the outer rail 42 is provided with a guide groove 421, the second rack 3 is provided with a guide post 31, and the guide post 31 moves in the guide groove 421 to drive the second rack 3 to move relative to the outer rail 42.

Preferably, at least four guiding posts 31 are disposed on two opposite sides of the second rack 3, and the four guiding posts 31 are symmetrically disposed.

As shown in fig. 3 and 4, at least four symmetrically distributed guide posts 31 are disposed on the inner sides of both sides of the second rack 3, that is, at least two guide posts 31 are disposed on the inner sides of the front side or the inner sides of the rear side; the outer rail 42 is provided with matched guide grooves 421, that is, the outer side of the front side or the outer side of the rear side of the outer rail 42 is provided with at least two guide grooves 421; the guiding column 31 can move along the guiding groove 421, so as to drive the second rack 3 to move up and down relative to the outer rail 42.

It can be seen that the second rack 3 is movably connected with the outer rail 42 by the cooperation of at least four sets of guiding columns 31 and guiding grooves 421; the second rack 3 can be driven by the outer rail 42 to stably move horizontally leftwards or rightwards, so as to achieve the effect of folding or unfolding, and meanwhile, the second rack 3 can also stably move upwards and downwards relative to the outer rail 42 without overturning or twisting; when the second rack 3 is moved upward to be horizontally level with the first rack 2, the full unfolding and flattening effect of the rack assembly is ensured, so that the user can conveniently store more articles.

Preferably, the guide slot 421 includes a sliding slot 4211 and a stopping slot 4212 connected with each other, the sliding slot 4211 forms an included angle with the stopping slot 4212, and the stopping slot 4212 limits the guide column 31 to limit the second rack 3 from moving in the first direction relative to the outer rail 42.

Preferably, the sliding groove 4211 has an included angle with the first direction, and the included angle is an obtuse angle or an acute angle.

Specifically, the guide groove 421 includes a sliding groove 4211 and a stopping groove 4212, which are communicated with each other and form an included angle; the sliding groove 4211 intersects with the vertical direction to form an obtuse angle or an acute angle, and is used for guiding the guide column 31 to move up and down; the stopper groove 4212 serves to limit the stopper guide post 31, thereby limiting the stopper second rack 3 from moving in the vertical direction.

It can be seen that when the second rack 3 moves left and right, the guiding column 31 is located at the bottom of the inclined guiding groove 421 and is limited, that is, the second rack 3 does not move up and down to generate vertical displacement, so as to improve the stability during sliding. Meanwhile, the stopping slot 4212 limits the guiding column 31 after the guiding column 31 reaches the topmost end of the guiding slot 421, so that the second rack 3 is prevented from moving up and down to improve stability, and the guiding column 31 can apply force upwards on the second rack 3 to overcome the influence of gravity.

Preferably, the inner contour of the guide groove 421 is L-shaped.

Specifically, the inner contour of the guide slot 421 is an inverted and inclined L-shape, that is, when the guide column 31 moves from one end of the guide slot 421 to the other end, it must cross over a right-angle step, and at this time, the second rack 3 is finally stopped by a limit after being displaced in the vertical direction, so that unstable phenomena such as sliding dislocation and the like due to displacement in the horizontal direction are avoided.

Preferably, the outer frame 1 is provided with a first position-limiting portion 122, the outer rail 42 is provided with a second position-limiting portion, and when the second rack 3 and the first rack 2 are separated from each other, the first position-limiting portion 122 and the second position-limiting portion cooperate to limit the outer rail 42 to move relative to the outer frame 1.

Preferably, the first position-limiting portion 122 is a position-limiting pillar 122, and the second position-limiting portion is a position-limiting groove 422.

Preferably, the restraint posts 122 are resilient restraint posts 122.

As shown in fig. 5 and 6, the outer rail 42 is provided with a limiting groove 422, the outer frame 1 is provided with elastic limiting posts 122 which are matched and symmetrical front and back, and the elastic limiting posts 122 and the limiting groove 422 are matched with each other to limit and fix the outer rail 42.

Optionally, the limiting grooves 422 are located at the right end of the outer rail 42, and the two elastic limiting columns 122 are located inside the right side frame of the outer frame 1.

When the second rack 3 and the first rack 2 are separated from each other without overlapping, the elastic limiting column 122 cooperates with the limiting groove 422 to limit and fix the outer rail 42, so that the second rack 3 can move in the vertical direction relative to the first rack 2 until the second rack 3 and the first rack 2 are horizontally aligned.

Therefore, the two elastic limiting columns 122 which are symmetrical front and back are arranged, so that the two outer rails 42 can be conveniently and quickly limited or released; after the outer rail 42 is fixed in a limited manner, the second rack 3 can smoothly move up and down, thereby achieving the overall unfolding or folding effect of the rack assembly.

In order to achieve the above object, the present invention further provides a refrigerator, which includes a box body and a rack assembly, wherein the rack assembly is disposed in the box body.

As shown in fig. 7 and 8, the shelf assembly in the folded or unfolded state has the following different states and specific processes:

Specifically, at least four guide posts 31 are arranged on the second rack 3 in a front-back symmetrical manner, and four matched guide grooves 421 are arranged on the outer rail 42 in a front-back symmetrical manner; the guide groove 421 includes a moving groove and a stopping groove 4212 which are distributed in an L shape; the guiding posts 31 are matched with the guiding grooves 421 to movably connect the second rack 3 with the outer rail 42, and meanwhile, the guiding posts 31 can move up and down along the moving grooves and enter the stopping grooves 4212 to be stopped by limit, that is, the second rack 3 can move up and down in the vertical direction and is limited by the limit.

In addition, the right end of the outer rail 42 is provided with a limiting groove 422, the outer frame 1 is provided with two matched elastic limiting columns 122 which are symmetrical front and back, and the elastic limiting columns 122 are matched with the limiting groove 422 to limit and fix the outer rail 42.

When the rack assembly is in the folded state, the second rack 3 is located below the first rack 2 and overlaps with the first rack 2.

When the rack assembly is changed to the unfolded state, the outer rail 42 slides rightward relative to the inner rail 41, and the guiding column 31 and the guiding groove 421 cooperate with each other to drive the second rack 3 to move rightward away from the first rack 2 until the second rack 3 reaches the rightmost end of the outer frame 1.

When the second rack 3 is completely separated from the first rack 2, the elastic position-limiting post 122 on the outer frame 1 cooperates with the position-limiting groove 422 at the right end of the outer rail 42 to fix the outer rail 42, and at this time, the guide post 31 can bring the second rack 3 to move upwards along the guide groove 421 until the second rack 3 is horizontally flush with the first rack 2 and is limited by the stop, that is, the rack assembly reaches the completely unfolded state.

When the rack assembly needs to be folded and stored, the guide post 31 moves from the stop groove 4212 to the moving groove until reaching the bottom end of the moving groove, at this time, the limiting groove 422 is separated from the elastic limiting post 122 to release the limiting of the outer rail 42, the outer rail 42 moves leftwards, the outer rail 42 drives the second rack 3 to move leftwards until the second rack 3 is completely overlapped below the first rack 2, and at this time, the rack assembly is in a folded state.

The rack assembly and the refrigerator with the same can solve the problems that most of the existing refrigerator racks cannot be folded left and right, and cannot slide smoothly when no support frame is arranged at the front end of the existing refrigerator racks, and the existing refrigerator racks slide stably without shaking or noise. After the rack assembly is folded, more space can be released for a user to store higher articles, so that the use convenience of the refrigerator is improved.
