[0037] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will provide a detailed description of the technical solutions of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0038] Embodiment 1

[0039] As Figures 1-7 shown, the present utility model provides a shelf assembly, including a shelf 2, a support 3, an adjustment mechanism, and a locking mechanism; where:

[0040] As Figure 2 shown, the number of supports 3 is two, which are arranged in parallel at intervals and are respectively fixed to the top of the accommodation cavity in the box body 1 by screws; the support 3 is a rectangular plate-like structure;

[0041] The shelf 2 is located in the accommodation cavity. Specifically, it is at the lower part or the bottom of the displacement accommodation cavity. The shelf 2 is movably connected to the support 3 through an adjustment mechanism and can perform a swinging horizontal lifting under the drive of the adjustment mechanism; it should be noted here that the swinging horizontal lifting means that the lifting mode of the shelf 2 swings around the connection point on the support 3, and during the swinging process, the shelf 2 is always in a parallel state to ensure that the items placed on the shelf 2 will not fall due to the lifting;

[0042] The locking mechanism is arranged between the adjustment mechanism and the shelf 2 to lock the position of the raised shelf 2.

[0043] The shelf assembly provided by the present utility model, by setting an adjustment mechanism and a locking mechanism, can lift the shelf 2 to the highest point in a swinging form in parallel through the adjustment mechanism, and then use the locking mechanism to lock the raised state of the shelf 2, so that when the user stores items on the lower shelf 2, the shelf 2 can be lifted parallel to the highest point for locking to place items. And when the user has stored the items, the locking state is unlocked through the locking mechanism to achieve the purpose of resetting the shelf 2. Through this shelf assembly, people do not need to bend down when accessing the materials at the bottom layer of the refrigerator.

[0044] Embodiment 2

[0045] In this embodiment, the structure of the adjustment mechanism is specifically defined.

[0046] As Figure 2 and Figure 3 shown, the adjustment mechanism includes a support seat 4, a connecting rod 5, and a rotating seat; where:

[0047] The support seats 4 are arranged on two opposite sides of the shelf 2, and the support seats 4 are vertically connected below the shelf 2; the support seats 4 are trapezoidal plate-like structures, facing the front side of the refrigerator, and the height of the support seats 4 is small.

[0048] The connecting rods 5 are respectively arranged on two sides of the shelf 2.

[0049] One end of the connecting rod 5 is rotatably connected to the support 3 through a rotating seat, and the other end of the connecting rod 5 is rotatably connected to the support seat through a rotating seat.

[0050] It should be noted here that the rotating seat is a cylindrical structure and has a rotating shaft inside; the bottom of the connecting rod 5 is connected to the rotating shaft inside the rotating seat, and the rotating seat and the support seat 4 are in a fixed connection relationship; through this structural setting, the connecting rod 5 can rotate relative to the rotating seat and the support seat 4. Since both ends of the connecting rod 5 are in a rotating connection relationship, when the connecting rod 5 is lifted, the shelf 2 can always remain horizontal.

[0051] In order to maintain the stability after lifting and the load-bearing capacity after putting items, in this embodiment, the connecting rod 5 includes four connecting rods 5 with the same specifications, and the four connecting rods 5 are divided into two groups and arranged in a rectangular distribution; one group of connecting rods 5 is arranged at two corners at the rear of the shelf 2, and the other group of connecting rods 5 is arranged on both sides at the front of the shelf 2; and there is a distance between the other group of connecting rods 5 and the front end of the shelf 2. By setting the distance, it is convenient for the shelf 2 to extend out of the box body 1 and ensure that the extension distance is long enough to facilitate the taking and placing of items.

[0052] As Figure 3 shown, the two groups of connecting rods 5 are respectively connected to the diagonal corners of the support 3. Among them, one group of connecting rods 5 located at the rear of the shelf 2 is connected to the lower left corner of the support 3, and one group of connecting rods 5 located at the front of the shelf 2 is connected to the upper right corner of the support 3. Through this structural setting, when the shelf 2 is lifted, the two groups of connecting rods 5 will not interfere with each other and remain in a parallel state.

[0053] Since the specifications of the connecting rods 5 are the same, the other ends of the two groups of connecting rods 5 are respectively connected to the diagonal corners of the support seat 4. Specifically, one group of connecting rods 5 located at the rear of the shelf 2 is connected to the lower left corner of the support seat 4, and one group of connecting rods 5 located at the front of the shelf 2 is connected to the upper right corner of the support seat 4.

[0054] The ends of the four connecting rods 5 enclose a parallelogram structure.

[0055] As Figure 2 and Figure 4 shown, the connecting rod 5 is connected to the end of the rotating seat, so that there is a gap between the connecting rod 5 and the edge of the shelf 2. By setting this gap, when the shelf 2 is lifted, the locking mechanism can pass through the gap to lock the position of the shelf 2.

[0056] Embodiment 3

[0057] As Figures 2-7 shown, as an alternative embodiment of the present utility model, the locking mechanism includes a pin 6, a claw 7, a chute 11, a pull rod 10, and a torsion spring 8; wherein:

[0058] The pin 6 is arranged on a connecting rod 5 at the front part of the shelf 2, and the pin 6 protrudes from the inner side of the connecting rod 5, that is, protrudes towards the shelf 2 side;

[0059] The chute 11 is opened on the support base. Considering that the shelf 2 is a swing-type lifting, the chute 11 is an arc-shaped structure;

[0060] One end of the claw 7 is rotatably arranged on the support base through the torsion spring 8, and the other end is snap-connected to the pull rod 10; in this embodiment, as Figure 3 、 Figure 6 and Figure 7 shown, the claw 7 is an L-shaped structure, one arm is arranged parallel to the outside of the support base 4, and the other arm is connected to the pull rod 10 after passing through the chute 11;

[0061] The pull rod 10 is a U-shaped structure and is slidably arranged at the bottom of the shelf 2. In order to ensure stable sliding, as Figure 6 shown, a limiting groove is arranged at the bottom of the shelf 2, and the pull rod 10 is slidably arranged in the limiting groove; and one end of the pull rod 10 is snap-connected to the claw 7, specifically hooked on the other arm of the claw 7, and the other end extends to the front part of the shelf 2; when the pull rod 10 is pulled, the claw 7 can be driven to rotate;

[0062] A clamping groove 12 capable of being snap-connected to the pin 6 is arranged on the claw 7.

[0063] Furthermore, the locking mechanism further includes columns 9 arranged on both sides of the claw 7 for realizing rotational limit.

[0064] To ensure smooth rotation and no interference, the distance between the outer wall of the claw 7 and the support base 4 is less than the interval width between the connecting rod 5 and the support base 4.

[0065] Embodiment 4

[0068] From Figure 2As can be seen, one end of the connecting rod 5 is fixed to the support 3, and the other end is fixed to the support base 4; the support 3 can be fixed to the inner liner of the box body 1 by means of screws; the support base 4 is fixed under the shelf 2; a pin column 6 is provided on the connecting rod 5; a claw 7 is provided on the support base 4.

[0069] As Figure 3 and Figure 4 shown, one end of the pull rod 10 is connected to the claw 7. As Figure 7 shown, the other end is connected to the support base 4. Pulling the pull rod 10 can cause the claw 7 to rotate on the sliding groove 11; a support column 9 is provided on the support base 4 to limit the rotation angle of the claw 7. As Figure 6 shown; a torsion spring 8 is provided on the claw 7, and the torsion spring 8 functions to reset the claw 7.

[0070] When the user needs to raise the shelf to store items, first lift the shelf 2 upward to the highest point. At this time, under the action of the torsion spring 8, the claw 7 is caught on the pin column 6 provided on the connecting rod 5 to achieve the purpose of locking the shelf. When the user has finished storing the items and needs to reset the shelf, pull the pull rod 10. The claw 7 rotates on the sliding groove 11 of the support base 4 under the drive of the pull rod 10. At this time, the claw 7 disengages from the pin column 6, releasing the lock of the shelf 2, and the shelf resets under the action of gravity.

[0071] The refrigerator provided by the present utility model is a small refrigerator. By providing an adjustment mechanism and a locking structure on the shelf 2 of the refrigerator, the user can lift the shelf 2 parallel to the highest point for locking to place items when storing items on the lower shelf 2.
