The bottle rack is generally connected to the pre-designed protrusions of the door lining through clips on the left and right sides of the bottle rack, and the upper and lower positions of the bottle rack cannot be adjusted arbitrarily. At the same time, storing items of mismatched heights can easily cause waste of bottle rack space.

[0003] At the same time, household refrigerators are sometimes equipped with flip-top bottle racks to place cosmetics and medicines. Flip-top bottle racks are often unable to place highly elevated items, and the number of such racks installed is also fixed, making it impossible to adjust the number of flip-top bottle racks according to user needs.

[0004] Patent No. CN208704282U discloses a flip-top bottle rack for refrigerators. The rack includes a bottle rack seat and a flip-top cover. Pulling a tray outward from the rack seat causes a rack gear to engage with a semi-toothed plate, which in turn causes the flip-top cover to rotate about a fixed column. The tray and flip-top form an access opening, making it easy for people to place and retrieve items. However, the rack has a height limit for placing items, preventing users from flexibly adjusting the rack to meet their needs. Utility Model Content

DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solution of the utility model.

[0036] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] The door of a household refrigerator 17 is usually equipped with a storage rack assembly, which mainly includes a bottle frame. The bottle frame is generally connected to the pre-designed protrusions of the door lining through the left and right clips of the bottle frame, and the upper and lower positions of the bottle frame cannot be adjusted arbitrarily. At the same time, storing items of mismatched heights can easily cause waste of bottle frame space.

[0039] Sometimes also flip-top bottle frame is housed and is placed cosmetics and medicine on the household refrigerator 17. Flip-top bottle frame often can't be placed the higher article of height, and its installation quantity is also fixed, can't adjust the quantity of using flip-top bottle frame according to user's demand.

[0040] like Figures 1 to 5 As shown, in order to solve the above problems, a storage rack for a refrigerator door 17 is proposed, the storage rack comprising a bracket 2 and a carrier 3 arranged on the bracket 2, the bracket 2 is provided with two opposite up and down slides 4, the carrier 3 is provided with two positioning blocks 5 that slide with the two slides 4 respectively, and a number of support members 18 for supporting the positioning blocks 5 are arranged along the slides 4, one end of the support member 18 is rotatably connected to the slide 4, and a limiting structure is provided between the support member 18 and the slide 4, the limiting structure allows the support member 18 to rotate freely upward at the position supporting the positioning block 5 but cannot rotate downward, and after the support member 18 rotates upward, the positioning block 5 can pass between the support member 18 and the slide 4 along the slide 4.

[0041] The support member 18 of this embodiment is a strip-shaped body. The limiting structure is a support portion 6 on the side wall of the chute 4, which is supported below the support member 18. The end of the support member 18 is rotatably connected to the side wall of the chute 4 via a hinge shaft 7, and the hinge shaft 7 is located above the support portion 6. To simplify the equipment, the bracket 2 is provided with protruding connecting portions 8 at both ends. The connecting portions 8 are fixedly connected to the inner wall of the refrigerator door 17 through the mounting holes by screws, forming the chute 4 between the bracket 2 and the inner wall of the refrigerator door 17.

[0042] The technical effect of adopting the above design is that after the support member 18 is rotated upward, the distance between the support member 18 and the side wall of the chute 4 is greater than the width of the positioning block 5, so that the carrier 3 moves upward. When the carrier 3 moves to a certain appropriate height, it can be supported downward on the support member 18 located below the positioning block 5. When it is necessary to move the carrier 3 downward, the support member 18 located below the positioning block 5 can be manually rotated so that the distance between the support member 18 and the side wall of the chute 4 is greater than the width of the positioning block 5. The width of the support member 3 is such that the support member 3 moves downward. When the support member 3 moves to a certain appropriate height, it can be supported downward on the support member 18 located below the positioning block 5, thereby achieving the height adjustment of the support member 3. Of course, the two ends of the chute 4 can also have developed ports so that the positioning block 5 can slide out of the chute 4 ports. In this way, when the position of the support member 3 needs to be lowered, the support member 3 can be slid out of the chute 4 from the upper port and then slid into the lower port to adjust the position upward from the bottom of the chute 4. The number of support members 3 can also be increased or decreased as needed.

[0043] like Figures 6 to 10 As shown, the support member 18 is provided with an upward-facing slot for supporting the positioning block 5. The slot is formed by two opposing baffles 9 provided on the support member 18, so that the support member 18 is F-shaped. The baffles 9 are in contact with the front and rear vertical surfaces of the positioning block 5, so that the positioning block 5 cannot rotate relative to the slot.

[0044] The technical effect of adopting the above design is that the slot is used to carry the positioning block 5 to prevent the positioning block 5 from moving forward and backward.

[0045] The side wall of the sliding groove 4 is provided with an accommodating hole 10 for the card slot to enter.

[0046] The technical effect of adopting the above design is that after the support member 18 rotates upward, the card slot enters the accommodating hole 10, so that there is a larger distance between the support member 18 and the side wall of the sliding groove 4.

[0047] like Figure 11 As shown, the bracket 2 is provided with a guide rail 11 parallel to the slide groove 4 , and the bearing member 3 is provided with a slide post 12 matched with the guide rail 11 .

[0048] The technical effect of adopting the above design is: the slide groove 4 and the guide rail 11 simultaneously guide the movement of the carrier 3, and the slide column 12 and the positioning block 5 simultaneously limit the carrier 3, so that the carrier 3 cannot slide out and rotate relative to the guide rail 11, thereby maintaining a stable positioning of the carrier 3.

[0049] like Figure 12 、 13 As shown, the guide rail 11 includes a guide groove that slidably cooperates with the slide post 12. The slide post 12 is a cylindrical body that can rotate relative to the guide groove. The positioning block 5 is retractably arranged on the bearing member 3 through a telescopic mechanism. An installation opening 13 is provided at one end of the guide groove for the slide post 12 to enter and exit the guide groove, thereby facilitating the removal of the bearing member 3.

[0050] The technical effect of adopting the above design is: the sliding column 12 is cylindrical, so that the sliding column 12 can rotate around its own axis relative to the slide groove 4, that is, the supporting member 3 can rotate around the cylindrical sliding column 12. At the same time, the telescopic mechanism is used to retract the positioning block 5 relative to the supporting member 3, so that the positioning block 5 is disengaged from the slide groove 4, thereby causing the supporting member 3 to flip up and down around the sliding column 12 relative to the bracket 2.

[0051] The telescopic mechanism includes a telescopic hole 14 provided on the carrier 3, the positioning block 5 slidingly cooperates with the telescopic hole 14, a return spring is supported between the positioning block 5 and the telescopic hole 14, and the positioning block 5 has a top pressing portion 15 inclined relative to the telescopic direction. The carrier 3 rotates around the slide column 12 so that the top pressing portion 15 is abutted by the side wall of the slide groove 4 and retracts, thereby causing the carrier 3 to flip up and down.

[0052] The technical effect of adopting the above design is: the pressing portion 15 inclined relative to the telescopic direction is provided on the positioning block 5. When the supporting member 3 rotates around the slide column 12 and the positioning block 5 contacts the side wall of the slide groove 4, the pressing portion 15 of the positioning block 5 contacts the side wall of the slide groove 4. Since the pressing portion 15 is inclined relative to the telescopic direction, the pressing force acting on the pressing portion 15 has a component force along the telescopic direction toward the telescopic hole 14. This component force overcomes the elastic force of the return spring and causes the positioning block 5 to retract into the telescopic hole 14, thereby causing the positioning block 5 to disengage from the slide groove 4, so that the supporting member 3 can continue to rotate relative to the bracket 2, thereby causing the supporting member 3 to flip up and down.

[0053] The carrier 3 is a storage box of the refrigerator 17. Several storage boxes are arranged on the bracket 2. The slide column 12 is located in the middle of the storage box in the horizontal direction, so that the upper storage box can be turned upside down on the lower storage box after being turned upside down.

[0054] The technical effect of the above design is that the sliding column 12 is located in the middle of the storage box in the horizontal direction, so that after the storage box is turned upside down, the upper storage box can be turned upside down on the lower storage box, which is equivalent to forming a storage box with a lid.

[0055] The end of the positioning block 5 has four surfaces, of which the upper and lower surfaces that can support on the support member 18 are supporting surfaces, the supporting surface is the inclined surface 16, and the other two surfaces are vertical surfaces. The pressing portion 15 is the edge where the inclined surface 16 intersects with the other surface.

[0056] The technical effect of adopting the above design is: when the supporting member 3 rotates, the position where the positioning block 5 contacts the side wall of the slide groove 4 is the edge where the inclined surface 16 intersects with the other supporting surface. The edge where the inclined surface 16 intersects with the other supporting surface is inclined relative to the telescopic direction, and the area of the edge is small at this time, and the edge is equivalent to line contact with the side wall of the slide groove 4, so the friction resistance of the positioning block 5 relative to the side wall of the slide groove 4 is small, which is conducive to using the top pressure to overcome the elastic force of the reset spring to make the positioning block 5 retract into the telescopic hole 14.

[0057] like Figure 14 As shown, the slope of the support slope is 10 degrees, and the friction coefficient between the slope and the support member is 0.2-0.4. That is, the fixed block is similar to a trapezoidal block, with the trapezoidal slope set to 10 degrees. The support member has a slope that aligns with the support surface, and the slope of the slope is consistent with that of the positioning block, which is 10 degrees.

[0058] The technical effect of adopting the above design is: regardless of whether the carrier is flipped or not, the positioning block and the support member are in support contact through the support surface. The positioning block and the support member are usually plastic parts. Since the support surface is an inclined surface, the positioning block will also be subjected to a certain force in the direction of the telescopic hole relative to the support member, and the magnitude depends on the gravity of the carrier and the slope of the inclined surface. At the same time, since the positioning block and the support member are in support contact through the support surface, there is friction between the two. This friction force hinders the positioning block from moving relative to the carrier. According to force analysis, when the friction coefficient u between the object on the inclined surface and the inclined surface is greater than the tangent value of the slope of the inclined surface, no matter how heavy the object is, it cannot slide. The friction coefficient between plastics is between 0.2 and 0.4, the slope of the inclined surface is 10°, tan10°=0.176, and the friction coefficient between the inclined surface and the support member is greater than the tangent value of its slope, that is, the positioning block and the support member will not slide relative to each other, that is, the positioning block will not be pressed and contracted by the support member under the action of gravity, thereby achieving the purpose of firmly positioning the bearing member on the bracket.
