Referring to fig. 5 to 8, the shelf 2 includes a cantilever 21 and a shelf 22.

The cantilever 21 is extended in the front-rear direction of the refrigerating compartment 10, and the shelf 22 is horizontally erected on the cantilever 21.

Two groups of cantilevers 21 are arranged, the two groups of cantilevers 21 are oppositely arranged in the refrigeration compartment 10 from left to right, and two ends of the shelf 22 are respectively erected on one cantilever 21.

The rear end of the cantilever 21 is detachably connected with the support seat 3. In some embodiments, a side wall of the rear end of the cantilever 21 is provided with a first fixing shaft 211 and a second fixing shaft 212 in a protruding manner, and the first fixing shaft 211 and the second fixing shaft 212 are arranged at intervals up and down. The supporting base 3 is provided with a first fixing hole 301 and a second fixing hole 302 which are spaced up and down.

When the fixing device is installed, the first fixing shaft 211 is inserted into the first fixing hole 301, and the second fixing shaft 212 is inserted into the second fixing hole 302. When the support is used, the cantilever 21 is hung on the support base 3 by matching with the gravity of the cantilever 21 and the whole layer frame 2, so that the first fixing shaft 211 is abutted against the inner wall of the first fixing hole 301, and the second fixing shaft 212 is abutted against the inner wall of the second fixing hole 302, so that the cantilever 21 is hung on the support base 3, and the whole layer frame 2 is hung on the support base 3.

Referring to fig. 7, in some embodiments, a flange 213 is formed on the top surface of the cantilever 21 and bent inward along the edge.

Fig. 9 is a schematic structural view of the guide rail 4, the support base 3 and the cantilever 21 in fig. 7. Fig. 10 is a schematic structural view of the support base 3 in fig. 9.

Referring to fig. 5 to 10, the supporting base 3 includes a sliding plate 31, a bending plate 32 and a connecting plate 33 which are integrally formed.

The sliding plate 31 extends vertically, and the sliding plate 31 is slidably connected to the guide rail 4.

In some embodiments, the sliding plate 31 is provided with rollers 34 on the side facing the adjacent side wall of the refrigerated compartment 10. The roller 34 is rotatably provided on the sliding plate 31, and the rotation axis of the roller 34 is perpendicular to the plate surface of the sliding plate 31 and arranged in the left-right direction of the refrigerating compartment 10. The rollers 34 are arranged in two and are arranged at intervals up and down. The rollers 34 may be provided in plural, vertically in a straight line and at intervals.

Referring to fig. 6, 8 and 10, the sliding plate 31 is slidably connected to the guide rail 4 through the roller 34. The rollers 34 can roll on the guide rail 4. It will be appreciated that the rollers 34 may be replaced by sliders, i.e. sliders provided on the side walls of the slide plate 31. The sliding plate 31 is slidably connected with the guide rail 4 through a sliding block, and both the sliding block and the roller 34 can be used as a sliding connecting piece, so that the sliding connection between the sliding plate 31 and the guide rail 4 is realized.

Referring to fig. 10 in conjunction with fig. 2 and 3, in some embodiments, the top of the sliding plate 31 is provided with a traction portion 311. The traction part 311 is located above the roller 34, and the traction part 311 is connected with a traction rope 52 in the driving mechanism. When the driving motor 51 controls the pulling rope 52 to gradually wind or gradually unwind, the pulling part 311 drives the sliding plate 31 to move up and down. Meanwhile, the supporting seat 3 can stably go up and down along the guide rail 4 by matching with the roller 34.

Referring to fig. 7 and 8, in some embodiments, the side wall of the guide rail 4 facing the support base 3 is recessed with a sliding groove 41 extending vertically. The roller 34 is accommodated in the chute 41 in a fitting manner, and is connected with the inner wall of the chute 41 in a rolling manner. If the slide block is used instead of the slide groove 41, the slide block is slidably connected to the inner wall of the slide groove 41.

The top and bottom of the guide rail 4 are respectively provided with a limiting bulge 42 on the inner wall of the sliding groove 41. The stop protrusion 42 can stop the roller 34 in the sliding groove 41, and prevent the roller 34 from moving upward away from the top of the sliding groove 41 or downward away from the bottom of the sliding groove 41.

Referring to fig. 6, the connecting plate 33 extends forward from an end of the bending plate 32 near the side wall of the refrigerating compartment 10. I.e. after bending of the bent plate 32, the connecting plate 33 can be as close as possible to the adjacent side wall of the refrigeration compartment 10.

Referring to fig. 6 and 9, the bending plate 32 is bent from the front end of the sliding plate 31 toward the adjacent side wall of the refrigerating compartment 10, so that an accommodating space 35 is formed between the sliding plate 31 and the bending plate 32. That is, a receiving space 35 is formed on the side wall surface of the support base 3 in a concave manner toward the center of the refrigerating space, and the receiving space 35 is laterally opened and the opening faces the adjacent side wall of the refrigerating compartment 10. The guide rail 4 is arranged in the area of the accommodating space 35, and the guide rail 4 is fixedly arranged on the adjacent side wall of the refrigeration compartment 10, i.e. the guide rail 4 is located between the sliding plate 31 and the adjacent side wall of the refrigeration compartment 10.

This structural layout can make the sliding plate 31 press close to the adjacent side wall of the refrigeration compartment 10 as much as possible, simplify the structure of the supporting seat 3, and reduce the thickness of the supporting seat 3 and the guide rail 4 in the left and right directions of the refrigeration compartment 10, thereby reducing the occupation of the internal space of the refrigeration compartment 10. Meanwhile, the size of the accommodating space 35 can be adjusted by changing the length of the bending plate 32 so as to adapt to guide rails 4 of different types or to adapt to refrigerators and refrigeration compartments 10 of different types.

Still referring to fig. 6 and 9, a connecting plate 33 extends forward from an end of the bending plate 32 near the side wall of the refrigerating compartment 10, and the connecting plate 33 is used for detachably connecting with the cantilever 21. After the bending plate 32 is bent, the connecting plate 33 can be as close to the adjacent side wall of the refrigeration compartment 10 as possible, so that the cantilever 21 connected with the connecting plate 33 can be as close to or as close to the adjacent side wall of the refrigeration compartment 10 as possible, and the occupation of the cantilever 21 on the internal space of the refrigeration compartment 10 is reduced.

Fig. 11 is a side view of fig. 10. Fig. 12 is a schematic structural distribution diagram of the first fixing holes 301 and the second fixing holes 302 in fig. 11. Fig. 13 is a schematic structural view of the cantilever 21 in fig. 9.

Referring to fig. 10 to 12, the connecting plate 33 extends in the vertical direction. The first fixing holes 301 and the second fixing holes 302 are provided in the connecting plate 33 at intervals in the vertical direction. When the first fixing shaft 211 on the cantilever 21 is inserted into the first fixing hole 301 and the second fixing shaft 212 is inserted into the second fixing hole 302, the front end of the cantilever 21 tends to descend due to the gravity of the cantilever 21 and the shelf 2, so that the first fixing shaft 211 is abutted against the front end of the first fixing hole 301 and the second fixing shaft 212 is abutted against the rear end of the second fixing hole 302.

Referring to fig. 11 and 13, in some embodiments, the first fixing hole 301 may be a cam hole having a shape similar to a cam, and having a large diameter at one end and a small diameter at the other end. The first fixing hole 301 extends in the front-rear direction, and the rear end portion of the first fixing hole 301 has a larger hole diameter than the front end portion thereof. Meanwhile, the first fixing shaft 211 is movably disposed in the first fixing hole 301, and a first limiting portion 2111 is disposed on a peripheral wall of the first fixing shaft 211 in a protruding manner along a circumferential direction. The outer diameter of the first stopper portion 2111 is smaller than the diameter of the rear end portion of the first fixing hole 301, and the outer diameter of the first stopper portion 2111 is larger than the diameter of the front end portion of the first fixing hole 301.

Therefore, when the first stopper 2111 passes through the rear end of the first fixing hole 301 and the first fixing shaft 211 passes through the first fixing hole 301, the front end of the cantilever 21 descends to allow the first fixing shaft 211 to abut against the front end of the first fixing hole 301, so that the first fixing hole 301 is clamped and limited between the first stopper 2111 and the side wall of the cantilever 21, and the first fixing shaft 211 is prevented from being detached from the first fixing hole 301.

Similarly, referring still to fig. 11 and 13, in some embodiments, the second fixing hole 302 may also be a cam hole. The second fixing hole 302 extends in the front-rear direction, and the front end portion of the second fixing hole 302 has a larger hole diameter than the rear end portion thereof. Meanwhile, the second fixing shaft 212 is movably disposed in the second fixing hole 302, and a second limiting portion 2121 is disposed on the peripheral wall of the second fixing shaft 212 along the circumferential direction. The outer diameter of the second stopper portion 2121 is smaller than the diameter of the rear end portion of the second fixing hole 302, and the outer diameter of the second stopper portion 2121 is larger than the diameter of the front end portion of the second fixing hole 302.

Therefore, when the second stopper 2121 passes through the front end of the second fixing hole 302 and the second fixing shaft 212 passes through the second fixing hole 302, the front end of the cantilever 21 descends to make the second fixing shaft 212 abut against the rear end of the second fixing hole 302, so that the second fixing hole 302 is clamped and limited between the second stopper 2121 and the sidewall of the cantilever 21, and the second fixing shaft 212 is prevented from being detached from the second fixing hole 302.

Fig. 14 is a schematic view of a first state in which the cantilever 21 and the support base 3 are mounted. Fig. 15 is a second state diagram illustrating the installation of the cantilever 21 and the support base 3. Fig. 16 is a third state diagram illustrating the installation of the cantilever 21 and the support base 3.

Referring to fig. 14 to 16 in combination with fig. 12, in some embodiments, the first fixing hole 301 and the second fixing hole 302 may be cam holes. At this time, the center of the rear end of the first fixing hole 301 and the center of the front end of the second fixing hole 302 are located on the same vertical line. The distance between the center of the rear end of the first fixing hole 301 and the center of the front end of the second fixing hole 302 is equal to the distance between the center of the front end of the first fixing hole 301 and the center of the rear end of the second fixing hole 302, as shown in fig. 12, and is just equal to the distance between the first fixing shaft 211 and the first fixing shaft 211.

When the cantilever 21 is mounted on the support base 3, the first stopper 2111 of the first fixed shaft 211 may be aligned with the rear end portion of the first fixing hole 301, while the second stopper 2121 of the second fixed shaft 212 may be aligned with the front end portion of the second fixing hole 302, as shown in fig. 14; further, the first 2111 and second 2121 stopper portions can be simultaneously inserted through the first fixing hole 301 and the second fixing hole 302, respectively, as shown in fig. 15. When the front end of the cantilever 21 is lowered in accordance with the gravity of the cantilever 21, the first fixing shaft 211 abuts against and is retained at the front end of the first fixing hole 301, and the second fixing shaft 212 abuts against and is retained at the rear end of the second fixing hole 302, as shown in fig. 16.

Referring to fig. 13 and 16, in some embodiments, on the cantilever 21, the first fixed shaft 211 is spaced above the second fixed shaft 212, and the second fixed shaft 212 is spaced at a rear side of the first fixed shaft 211. The first fixing shaft 211 and the second fixing shaft 212 are inclined forward and backward.

When the cantilever 21 is installed, the front portion of the cantilever 21 may be lifted up by a certain angle, so that the first stopper 2111 of the first fixing shaft 211 is aligned with the rear end portion of the first fixing hole 301, and the second stopper 2121 of the second fixing shaft 212 is aligned with the front end portion of the second fixing hole 302, and then the first fixing shaft 211 and the second fixing shaft 212 are inserted into the first fixing hole 301 and the second fixing hole 302, respectively, so that the cantilever 21 may smoothly fall down by the gravity of the cantilever 21 itself, and when the cantilever 21 is finally installed in place, the cantilever 21 may be maintained in a horizontal state.

When the first fixing shaft 211 abuts against the front end of the first fixing hole 301 and the second fixing shaft 212 abuts against the rear end of the second fixing hole 302, the cantilever 21 can be extended horizontally, so that the shelf 22 can be horizontally disposed even if the top of the cantilever 21 is kept horizontal, thereby keeping the overall horizontal state of the shelf 2.

When the shelf 2 is installed, the left and right groups of cantilevers 21 may be installed with the corresponding support bases 3, and then the shelf 22 is clamped or fixed to the cantilevers 21, so as to finally complete the installation of the shelf 2. The layer frame 2 of the connecting structure has a simple structure, is simple and reliable to install, is favorable for reducing the cost and improves the assembly efficiency.

Based on the technical scheme, the embodiment of the invention at least has the following advantages and positive effects:

in the refrigerator of the embodiment of the invention, the layer frame 2 and the guide rail 4 are connected through the supporting seat 3, so that the layer frame 2 can slide on the guide rail 4 along with the supporting seat 3. The guide rail 4 is disposed on the inner side wall of the refrigeration compartment 10, the supporting seat 3 is concavely provided with an accommodating space 35, the accommodating space 35 faces the adjacent side wall of the refrigeration compartment 10, and the accommodating space 35 is used for the guide rail 4 to be arranged.
