The slide rod is exposed in the storage compartment, and it may be stained with the stored food residues and other stains after long-term use, causing the slide rod to get stuck. At the same time, the volume of the adjustment structure is large, which occupies the storage space and reduces the effective volume of the refrigerator storage compartment.

[0028] See also Figure 1 The utility model provides a height continuous adjustment component, comprising a tray 1 arranged on an upper layer and a lower layer; both sides of the two trays 1 are connected by a scissor frame;

[0029] The scissor rack includes at least two vertically connected cross rod groups, and the two trays 1 are respectively connected to a cross rod group; the cross rod group includes two rotatably connected support rods 2, and the rotation connection point is located at the center of the support rod 2;

[0030] A slide groove 11 is respectively provided on both sides of the tray 1;

[0031] Two support rods 2 of the same cross rod group: one end of one support rod 2 is rotatably connected to the tray 1, one end of the other support rod 2 is connected to the moving member 3 that can reciprocate in the slide slot 11, and the other ends of the two support rods 2 are rotatably connected to the support rods 2 of the adjacent cross rod group respectively;

[0032] A synchronization rod 4 is provided at the bottom of one of the pallets 1, which connects the two moving parts 3 of the pallet 1; the synchronization rod 4 is connected to a power member for transmission, and the power member is configured to: drive the synchronization rod 4 to reciprocate along the direction of the slide groove 11, thereby causing the two moving parts 3 connected to the synchronization rod 4 to move synchronously, changing the angle between the two support rods 2 of the cross rod group, and thereby changing the distance between the two pallets 1.

[0033] Optionally, there is a certain matching gap between the moving member 3 of the utility model and the slide groove 11, so that the resistance of the moving member 3 moving in the slide groove 11 is small, and the distance between the two trays 1 can be smoothly adjusted.

[0034] As a preferred solution, the synchronization rod 4 and the power component of the utility model are installed at the bottom of the tray 1 located in the lower layer, so as to avoid the synchronization rod 4 and the power component being located between the two trays 1, and the risk of the stored items touching the synchronization rod 4 or the power component when adjusting the spacing.

[0035] As a preferred solution, the length of the support rod 2 of the utility model is smaller than the width of the pallet 1. When the support rod 2 is in a horizontal position, it does not exceed the boundary of the pallet 1, making the overall structure compact and suitable for narrow spaces or closed spaces.

[0036] The cross bar group of the scissors rack of the utility model can be 3-5 groups, and each cross bar group is connected in sequence along the vertical direction; the length of the support bar 2 of each cross bar group can be much smaller than the width of the pallet 1, such as the length of the support bar 2 is 1 / 3, 1 / 4 or 1 / 5 of the width of the pallet 1; by connecting multiple groups of cross bar groups, a larger height of layer spacing adjustment can be achieved with shorter support bars 2.

[0037] See also Figure 2 As an embodiment of the power member, the power member includes a transmission screw 41 threadedly connected to the synchronization rod 4; one end of the transmission screw 41 is rotatably arranged on the tray 1, and the other end is transmission-connected to a driving motor 42 fixedly arranged at the bottom of the tray 1;

[0038] The moving stroke of the synchronization rod 4 in this embodiment is relatively large, so that a relatively large range of adjustment of the distance between the two trays 1 can be achieved.

[0041] The synchronization rod 4 of this embodiment only bears the thrust or pulling force of the driving cylinder 43 during the movement, and does not bear the torsion force, so it is not easy to get stuck.

[0042] As an embodiment of the movable part 3 of the utility model, the movable part 3 is a cylinder; one end face of the cylinder is fixedly connected to the support rod 2, and the other end face is rotatably connected to the synchronization rod 4; when the synchronization rod 4 pushes the movable part 3 to move in the slide groove 11, the movable part 3 rotates at the same time to adapt to the angle change of the support rod 2.

[0043] The structure and connection relationship of the moving part 3 in this embodiment are simple and the manufacturing cost is low.

[0044] As an embodiment of the movable member 3 of the utility model, the movable member 3 is a roller; the two sides of the roller are rotatably connected to the support rod 2 and the synchronization rod 4 respectively; the synchronization rod 4 pushes the roller to roll in the slide groove 11, reducing the resistance, making the layer distance adjustment smoother.

[0045] See also Figure 4 As an embodiment of the moving member 3 of the utility model, the moving member 3 is a slider, one side of the slider is rotatably connected to the support rod 2, and the other side is fixed to the synchronization rod 4; the top and bottom surfaces of the slider are respectively embedded with a plurality of balls 31 that abut against the inner wall of the slide groove 11; when the synchronization rod 4 pushes the slider to move in the slide groove 11, the balls 31 roll to reduce resistance. The balls 31 of the slider abut against the inner wall of the slide groove 11, eliminating the matching gap between the moving member 3 and the slide groove 11, reducing noise, and making the layer spacing adjustment quieter and smoother.

[0046] The height continuous adjustment component of the utility model adjusts the distance between two trays 1 through a scissor frame; the adjustment range is continuous and reliable, the overall structure is compact, and can be used for continuous adjustment of the layer distance in a narrow or closed space.

[0047] See also Figure 5 The utility model also provides a shelf mechanism with stepless adjustment of layer spacing, comprising at least two groups of height-continuously adjustable components stacked in sequence from bottom to top; the layer spacing of each height-continuously adjustable component can be adjusted independently and continuously, and each layer can adaptively adjust the corresponding layer spacing according to the actual stored items, which has high flexibility.

[0048] Preferably, the shelf mechanism with stepless adjustment of layer spacing of the utility model has at least three groups of continuous height adjustment components; it is suitable for storage spaces with small areas and large heights.

[0049] See also Figure 6The utility model also provides a refrigeration device, including at least one storage compartment, wherein at least one storage compartment is provided with the above-mentioned shelf mechanism with stepless adjustment of layer distance; the multiple adjustment components of the shelf mechanism divide the storage compartment into multiple layers of storage space, and the layer height of each storage space can be adjusted independently, and the adjustment process is smooth and continuous. It is suitable for storing objects of different heights, and improves the flexibility and diversity of the storage objects of the refrigeration device.
