Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a switch structure arranged on a refrigerator shelf. Background Technology

[0002] Most modern refrigerators have a separate crisper drawer at the bottom of the refrigerator compartment. This crisper drawer is separated from the refrigerator compartment by a shelf at the top. A ventilation hole is located between the crisper drawer and the refrigerator compartment to adjust the airflow. This ventilation hole can be located on the shelf, the side of the crisper drawer, or the front of the crisper drawer. An adjustment switch is located on the top of the shelf, connecting to an adjustment mechanism at the bottom of the shelf. This adjustment mechanism allows for adjustment of the size of the ventilation hole between the crisper drawer and the refrigerator compartment, thus adjusting the crisper drawer's crisperness. However, current methods use screws to directly connect the adjustment switch and the adjustment mechanism. This method is time-consuming during production, and it's crucial to ensure the screws aren't over-tightened, otherwise, it may damage the adjustment mechanism or the switch. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a switch structure arranged on a refrigerator shelf that is easy to assemble and can ensure strength.

[0005] A shelf, wherein the shelf is provided with strip-shaped operating holes;

[0006] An adjusting plate body, the adjusting plate body including an operating end and a closed end, the adjusting plate body being arranged at the bottom of the shelf, and the adjusting plate body being able to move along the direction restricted by the operating hole;

[0007] An adjustment handle is disposed on the upper surface of the shelf;

[0008] An interlocking structure is provided, comprising a connecting platform and a fixed base. The connecting platform has connecting holes on both sides, with the inner end face of the connecting hole serving as a first abutment surface. The fixed base includes two mating parts arranged facing each other. A connecting block is provided on the inner side of each mating part, and the side of the connecting block facing away from the connecting hole serves as a second abutment surface. The mating parts are located on both sides of the connecting platform, and the connecting block is inserted into the connecting hole so that the first abutment surface abuts against the second abutment surface. An auxiliary guide surface is provided on the facing surfaces of the connecting block and / or the connecting platform. The connecting platform and the fixed base are respectively located at the top of the operating end and the bottom of the adjusting handle.

[0009] As a further improvement to the above technical solution, the connecting platform is located at the top of the operating end, and the fixing seat is located at the bottom of the adjusting handle.

[0010] As a further improvement to the above technical solution, the mating parts are two mating plates arranged in parallel at the bottom of the adjusting handle, the connecting block is arranged in the middle of the inner side of the mating plates, and the fixing seat also includes two connecting plates that are respectively connected to the two ends of the mating plates.

[0011] As a further improvement to the above technical solution, the mating plate is provided with a topological hole extending to the bottom of the adjustment handle, and the second abutting surface is flush with the bottom surface of the topological hole.

[0012] As a further improvement to the above technical solution, the lower surface of the connecting block is provided with the auxiliary guide surface, and the guide auxiliary surface provided on the connecting block is a guide slope that is inclined towards the outside of the mating part.

[0013] As a further improvement to the above technical solution, the upper surface of the connecting platform is provided with the auxiliary guide surface, which is an arc-shaped surface with the middle of the connecting platform as the vertex and gradually inclined to both sides.

[0016] As a further improvement to the above technical solution, the two sides of the strip track are provided with wavy resistance teeth, which are interference-fitted with the inner wall of the strip receiving groove.

[0017] As a further improvement to the above technical solution, the bottom surface of the strip track is provided with a number of arc-shaped auxiliary protrusions, which abut against the bottom surface of the strip receiving groove and force the first abutting surface to abut against the second abutting surface.

[0018] The beneficial effects of this utility model are as follows: During installation, this solution only requires placing the adjusting handle above the shelf and installing the adjusting plate below the shelf. At this time, the connecting platform and fixing seat located at the operating end of the adjusting handle and adjusting plate will be inserted into the operating hole. When the connecting platform and fixing seat move towards each other, the connecting platform will first be positioned between the two mating parts.

[0029] Reference Figures 1 to 5 A switch structure arranged on a refrigerator shelf includes:

[0030] A shelf 10, wherein the shelf 10 is provided with strip-shaped operation holes 11;

[0031] Adjustment plate 20, the adjustment plate 20 includes an operating end 21 and a closed end 22, the adjustment plate 20 is arranged at the bottom of the shelf 10, and the adjustment plate 20 can move along the direction restricted by the operating hole 11;

[0032] Adjustment handle 30, the adjustment handle 30 includes an adjustment handle 30 located on the upper surface of the shelf 10;

[0033] An interlocking structure is provided, comprising a connecting platform 40 and a fixing base 50. The connecting platform 40 has connecting holes 41 on both sides, and the inner end face of the connecting holes 41 is a first abutting surface 411. The fixing base 50 includes two mating parts arranged facing each other. A connecting block 52 is provided on the inner side of the mating parts. The side of the connecting block 52 facing away from the connecting holes 41 is a second abutting surface 53. The mating parts are respectively located on both sides of the connecting platform 40, and the connecting block 52 is inserted into the connecting holes 41 so that the first abutting surface 411 abuts against the second abutting surface 53. The opposing surfaces of the connecting block 52 and / or the connecting platform 40 are provided with auxiliary guide surfaces. The connecting platform 40 and the fixing base 50 are respectively located at the top of the operating end 21 and the bottom of the adjusting handle 30.

[0034] During installation, this solution only requires placing the adjustment handle 30 above the shelf 10 and installing the adjustment plate 20 below the shelf 10. At this time, the connecting platform 40 and the fixing seat 50, which are located on the operating end 21 of the adjustment handle 30 and the adjustment plate 20, will be inserted into the operating hole 11. When the connecting platform 40 and the fixing seat 50 move towards each other, the connecting platform 40 will first be located between the two mating parts. Through the auxiliary guide surface provided on the surface of the connecting block 52 and / or the surface of the connecting platform 40 facing each other, the mating parts will first open outward on the surface of the connecting platform 40. Then, the connecting platform 40 will move towards the inside of the mating parts until the connecting block 52 coincides with the connecting hole 41. Then, the connecting block 52 will be inserted into the connecting hole 41, so that the first abutting surface 411 and the second abutting surface 53 abut together to complete the installation. The whole process is quick and convenient, and because the operating end 21 of the adjusting plate 20 and the adjusting handle 30 are interlocked through the first contact surface 411 and the second contact surface 53, the adjusting plate 20 and the adjusting handle 30 are not easy to come loose.

[0035] In this design, the connecting platform 40 is preferably located at the top of the operating end 21, and the fixing seat 50 is located at the bottom of the handle. Alternatively, the arrangement can be reversed, with the connecting platform 40 located at the bottom of the handle and the fixing seat 50 located at the top of the operating end 21.

[0036] The mating component can be an independent elastic rod. Considering structural strength, in order to avoid damage to the mating component, the mating component is preferably two mating plates 51 arranged in parallel at the bottom of the adjusting handle 30. The connecting block 52 is arranged in the middle of the inner side of the mating plate 51. The fixing seat 50 also includes two connecting plates 55 that are respectively connected to the two ends of the mating plate 51.

[0037] Further optimization is preferred, with a topological hole 54 extending to the bottom of the adjustment handle 30 provided on the mating plate 51, and the second abutment surface 53 being flush with the bottom surface of the topological hole 54, thereby saving material usage while ensuring strength.

[0038] In this design, it is preferable that both the lower surface of the connecting block 52 and the upper surface of the connecting platform 40 are provided with auxiliary guide surfaces. Preferably, the auxiliary guide surface on the connecting block 52 is a guide slope 521 that slopes outwards towards the mating part, while the auxiliary guide surface on the connecting platform 40 is an arc-shaped surface 43 that slopes gradually to both sides with the center of the connecting platform 40 as its apex. Of course, in other embodiments, the auxiliary guide surfaces on the connecting block 52 and the connecting platform 40 can be either arc surfaces or slopes.

[0039] To further optimize the design and save materials, and to ensure that the connecting block 52 can be engaged into the connecting hole 41 to the greatest extent, it is preferable that the bottom of the operating end 21 is provided with a chamber 42 extending into the inner side of the connecting platform 40, and the connecting hole 41 communicates with the chamber 42.

[0040] To further optimize the adjustment plate 20 and make its movement more precise, it is preferable that the bottom surface of the layer plate 10 is provided with a strip track 13 arranged around the outer periphery of the operating hole 11, and the top surface of the operating end 21 is provided with a strip receiving groove 211 into which the strip track 13 is inserted. However, in order to ensure that the adjustment plate 20 still has a certain resistance when moving and thus will not be easily knocked away, it is preferable that the two sides of the strip track 13 are provided with wavy resistance teeth 131, and the resistance teeth 131 are interference-fitted with the inner wall of the strip receiving groove 211.

[0041] Further optimization involves the bottom surface of the strip track 13 preferably having several arc-shaped auxiliary protrusions 132. These auxiliary protrusions 132 abut against the bottom surface of the strip-shaped receiving groove 211, forcing the first abutting surface 411 to abut against the second abutting surface 53. This design aims to position the adjusting plate 20 further downwards, thereby tensioning the adjusting plate 20 and the adjusting handle 30, ensuring the first abutting surface 411 and the second abutting surface 53 remain in contact, thus improving the interlocking effect between them.

[0042] Further optimization: In this solution, the ventilation hole 12 is preferably located on the shelf 10, and the closed end 22 preferably includes a strip-shaped closing plate with a through hole 221 running vertically through it. When the closed end 22 moves, the through hole 221 gradually overlaps with the ventilation hole 12. In other embodiments, the closed end 22 may be a cover plate, and the ventilation hole 12 is gradually closed by moving the cover plate.

[0043] To further optimize the system, since the adjustment plate 20 is connected to the adjustment handle 30 at the operating end 21, in order to balance the force, it is preferable that an elastic plate 60 located outside the ventilation hole 12 is provided on the bottom surface of the shelf 10. A wedge block 61 is provided on the elastic plate 60, and the top surface of the wedge block 61 abuts against the bottom surface of the closed end 22, so that the operating end 21 is also supported by the wedge block 61, so that the adjustment plate 20 is subjected to balanced force and is not prone to deviation.

[0044] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
