The clamping assembly can be matched with the layer frame 2 at any position of the sliding groove 11 to clamp the cover plate 1, so that the layer frame 2 is fixed. Therefore, the adjustable shelf structure provided by the embodiment of the invention can realize stepless adjustment, the adjustment precision of the distance between shelves is high, and the space in the refrigerator can be more fully utilized.

Optionally, the clamping assembly includes a sliding block 3, the sliding block 3 is disposed through the sliding groove 11, the sliding block 3 is slidably connected with the layer frame 2, the sliding block 3 can horizontally slide in a direction perpendicular to the cover plate 1 relative to the layer frame 2, a clamping portion 31 is disposed at one end of the sliding block 3 located at the rear side of the cover plate 1, and the clamping portion 31 has a horizontal width W in a direction parallel to the cover plate 1₁Is greater than the width W of the chute 11₂So that the clamping portion 31 is always disposed through the chute 11; the slide 3 is slid forward in the horizontal direction to a first position, so that the clamping portion 31 and the shelf 2 cooperate to clamp the cover plate 1, as shown in fig. 3 and 7. The clamping assembly utilizes the chute structure on the cover plate 1, not only realizes the fixation of the layer frame 2, but also realizes the sliding connection between the layer frame 2 and the cover plate 1, compared with the independently arranged clamping assembly (namely, the clamping assembly is arranged and clamped on the layer frame 2A matched slideway), the structure of the scheme is simpler.

Based on the above embodiment, the adjustable shelf structure for the refrigerator according to the embodiment of the invention further includes the transmission locking assembly 4, the transmission locking assembly 4 can apply a force to the sliding block 3 to move forward relative to the cover plate 1, and when the sliding block 3 moves to the first position, the transmission locking assembly 4 can lock the position of the clamping assembly, so that the shelf 2 is locked.

Optionally, slider 3 accessible connecting rod drive to set up limit structure on layer frame 2, through limit structure with the connecting rod locking, transmission locking subassembly 4 includes connecting rod and limit structure promptly, because of the connecting rod design is more complicated, and the precision is not high. Therefore, the driving locking assembly 4 of the present embodiment preferably includes a driving cable 41, a handle 42 and a locking device 43, wherein one end of the driving cable 41 is connected to the sliding block 3, the other end is connected to the handle 42, the handle 42 can rotate relative to the shelf 2, and the handle 42 can conveniently tension the driving cable 41 with less effort. Of course, when the handle 42 is rotated to the first position (i.e. the position shown in fig. 5), the handle 42 can pull the driving cable 41, so that the clamping portion 31 of the sliding block 3 and the shelf 2 clamp the cover plate 1, and the handle 42 is locked by the locking device 43, as shown in fig. 4-5. When the shelf 2 is in the clamping state, the handle 42 is always in the first position, and the clamping force of the clamping assembly is relatively reliable.

The locking device 43 includes a fixed portion 431, a rotating portion 432 and a locking member 433, wherein the fixed portion 431 is fixed with respect to the shelf 2 (for example, the fixed portion 431 is mounted on the shelf 2), the rotating portion 432 rotates with respect to the fixed portion 431, and the handle 42 is fixed on the rotating portion 432. When the rotating part 432 rotates in the first direction (P direction in fig. 6) relative to the fixing part 431, the handle 42 is driven to tighten the driving cable 41. Alternatively, when the lock member 433 is in the lock position, the lock member 433 allows the rotating portion 432 to rotate in a first direction with respect to the fixed portion 431 and prevents the rotating portion 432 from rotating in a second direction (M direction in fig. 5) opposite to the first direction with respect to the fixed portion 431; or when the lock member 433 is in the lock position, the lock member 433 prevents the rotating portion 432 from rotating in the first direction or the second direction with respect to the fixed portion 431. The former lock member 433 allows the rotating portion 432 to rotate in a first direction relative to the fixing portion 431, and when the transmission cable 41 needs to be tensioned, the handle 42 is directly rotated in the first direction; in the latter solution of the locking member 433, when the handle 42 needs to be rotated to rotate in the first direction, the locking member 433 will prevent the rotating portion 432 from moving in the first direction relative to the fixing portion 431, so that the operation of moving the locking member 433 away from the locking position is troublesome and laborious, and therefore, the former solution of the locking member 433 is preferably adopted in the embodiment of the present invention, as shown in fig. 5 to 6.

Alternatively, the fixing portion 431 may be a gear fixed on the shelf 2; the rotating part 432 includes a rotating bracket rotatably connected to the shelf 2, and the rotating shaft of the rotating bracket is coaxial with the axis of the gear, and the handle 42 is fixed on the rotating bracket. The locking member 433 includes a positioning rod 4331 and a reset member 4332, wherein the positioning rod 4331 is slidably connected in the rotating bracket, the reset member 4332 is connected to the positioning rod 4331, and a guide inclined surface 4331a is formed at a side of a first end (i.e., an end close to the gear) of the positioning rod 4331 facing the first direction. When the rotating bracket rotates along the first direction, the guiding inclined surface 4331a of the first end of the positioning rod 4331 presses the teeth of the gear, the guiding inclined surface 4331a converts the force applied by the gear in the second direction into a force horizontally away from the gear, so that the positioning rod 4331 moves in the direction away from the gear until the positioning rod 4331 rotates to the first position, the reset piece 4332 applies the force to the positioning rod 4331 to move in the direction close to the gear, so that the first end of the positioning rod 4331 can extend between two adjacent teeth of the gear, and the rotating bracket is locked, as shown in fig. 5. Alternatively, the fixing portion 431 may be a rotating bracket, the rotating portion 432 is a gear, and the handle 42 is fixed to the gear, so that the gear is rotated by the handle 42 to adjust the clamping position of the gear and the rotating bracket, thereby tightening the transmission cable 41.

The reset element 4332 can be a spring, a hydraulic cylinder, etc., and the spring is cheaper and is simple to install and replace. Therefore, it is preferable that the restoring member 4332 in the embodiment of the present invention is a spring, one end of which abuts against the rotating bracket and the other end of which abuts against the positioning rod 4331, as shown in fig. 5. When the rotating bracket rotates along a first direction, the guide inclined surface 4331a on the positioning rod 4331 moves along the tooth surface of the gear and interacts with the tooth surface of the gear, so that the positioning rod 4331 moves towards the direction away from the gear, and the spring is extruded to generate deformation; if the positioning rod 4331 moves to the first position, i.e. between two teeth at the first position of the gear, the external force is removed, and the positioning rod 4331 is tightly clamped with the gear under the action of the restoring force of the spring.

In order to increase the clamping force between the clamping portion 31 and the cover plate 1, the embodiment of the present invention is provided with the friction pad 5 between the clamping portion 31 and the cover plate 1, as shown in fig. 7, so that the friction force between the clamping portion 31 and the cover plate 1 is increased, and the clamping force between the clamping portion 31 and the cover plate 1 is more reliable. Alternatively, the friction pad 5 may be made of a polyurethane material, which has good strength and high elongation at break, and excellent friction and wear properties.

Optionally, a horizontal guide rail 6 is arranged on the shelf 2, the horizontal guide rail 6 is perpendicular to the cover plate 1, and the sliding block 3 is in sliding fit with the horizontal guide rail 6, so that the sliding block 3 can move along the horizontal guide rail 6, as shown in fig. 3. The horizontal guide rail 6 can be arranged on the lower surface of the shelf 2 and can also be arranged on the side surface of the shelf 2, and the horizontal guide rail 6 is arranged on the lower surface of the shelf 2, so that the shelf 2 has higher mechanical strength and more reliable supporting force. Therefore, it is preferable that the embodiment of the present invention may dispose the horizontal guide rail 6 on the lower surface of the shelf 2.

If the driving cable 41 is long, the position of the driving cable 41 is changed when the driving cable 41 is in the release state, and it is hard to tighten the driving cable 41. Therefore, the embodiment of the present invention provides the guide member 61 on the horizontal guide rail 6, the guide member 61 is located between the slider 3 and the handle 42, as shown in fig. 3, the guide member 61 can change the direction of the pulling force of the driving cable 41, so that the driving cable 41 moves in the preset direction, and the handle 42 is more labor-saving to pull the driving cable 41.

Alternatively, the guide 61 may be a guide post or a directional pulley, which is complicated and costly. Therefore, the embodiment of the present invention adopts the scheme of the guide post, the transmission cable 41 is wound around the guide post, and the transmission cable 41 moves along the traction direction of the guide post.

Furthermore, the cover plate 1 is made of plastic, so that the cover plate 1 can be conveniently formed and processed, and the refrigerator can be conveniently cleaned. However, the cover plate 1 made of plastic has low mechanical strength, and in order to prevent the transmission cable 41 and the sliding block 3 from being in clamping fit with the sliding groove 11 on the cover plate 1 for a long time, the sliding groove 11 is easy to deform or damage, so that the metal guide rail is embedded in the inner wall of the sliding groove 11 in the embodiment of the invention, the mechanical strength of the metal guide rail is high, and the structural strength of the sliding groove 11 can be improved.

The embodiment of the invention also comprises a refrigerator which comprises a refrigerator chamber, wherein the adjustable shelf structure in the embodiment is arranged in the refrigerator chamber. Wherein, the apron 1 of adjustable layer frame structure is connected with the back wall of refrigerator inner bag, and apron 1 is equipped with two parallel spouts 11, correspondingly, the lower extreme of layer frame 2 is equipped with the tight subassembly of clamp with spout 11 complex, further strengthens the tight intensity of clamp of layer frame. Since the adjustable shelf structure installed in the refrigerator of the present embodiment is the same as that provided in each of the embodiments of the adjustable shelf structure for a refrigerator described above, both can solve the same technical problems and achieve the same intended effects.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
