Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more specifically, to a refrigerator door adjustment device. Background Technology

[0002] As living standards continue to improve, people have higher requirements for kitchen renovations. Integrated kitchens, with their high space utilization, strong sense of unity, and aesthetic appeal, are particularly popular. To integrate a refrigerator into an integrated kitchen, it needs to be built-in into cabinets or walls. Built-in refrigerators typically use variable-track hinges, allowing the distance between the refrigerator door and the sides of the cabinets to be as small as 3mm or even less. This places extremely high demands on the precision of the cabinet width. If there is a 1-2mm error in the cabinet width, or a 1-2mm tilt or deformation in the cabinet's vertical direction, the refrigerator door may not be able to open properly. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigerator door adjustment device, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0004] A refrigerator door adjustment device includes a pre-embedded box located on the lower frame of the door, a lower hinge seat located below the pre-embedded box, and the following components are assembled inside the pre-embedded box: a wedge block, a lower hinge shaft, a connector, an adjustment base, a lifting structure, a sliding rod, and a sliding block.

[0005] The wedge block is fixedly installed on the top wall of the pre-embedded box, and the bottom of the wedge block is a slope.

[0006] The lower hinge shaft is vertically fixedly installed on the top surface of the lower hinge seat;

[0007] The connector is provided with a lower track groove that mates with the lower hinge shaft. The lower hinge shaft is located in the lower track groove. When the connector is rotated, the lower hinge shaft can move along the lower track groove.

[0008] The bottom surface of the adjustment base is provided with a limiting groove that matches the lower track groove. The limiting groove protrudes upward and forms a boss on the top surface of the adjustment base. The adjustment base is fixedly installed on the connector, and the lower track groove is located in the limiting groove. There are upright plates symmetrically arranged on the left and right sides of the top surface of the adjustment base. Each upright plate has a through hole. At the connection position between one of the upright plates and the adjustment base, there are two L-shaped installation notches along the front and rear direction.

[0009] The lifting structure has two sets, which are installed one-to-one with the two L-shaped mounting notches. The lifting structure includes a lifting adjustment rod, and the top of the lifting adjustment rod is integrally formed with a mounting block. The mounting block is provided with an elongated through hole, which connects the front and rear sides of the mounting block and is arranged at an angle. A connecting shaft is provided in the elongated through hole, which can slide along the length of the elongated through hole. The bottom of the lifting adjustment rod is provided with a blind hole, and a limit buckle is provided at the end of the blind hole. A fixing nut is installed in the limit buckle. The fixing nut is threadedly connected to a capped screw rod. A double-layer flange is fixedly fitted on the capped screw rod near the nut. The double-layer flange is locked in the L-shaped mounting notch. By rotating the capped screw rod, the lifting adjustment rod can move up and down in the vertical direction.

[0010] One end of the sliding rod passes through the through hole on the left upright plate and the other end passes through the through hole on the right upright plate. A strip-shaped mounting hole is provided on the sliding rod. The mounting block in the first set of lifting structures is located in the strip-shaped mounting hole, and the two ends of the connecting shaft are perpendicularly connected to the inner wall of the strip-shaped mounting hole. In the first set of lifting structures, the lifting adjustment rod drives the mounting block to move up and down, which enables the sliding rod to slide left and right, thereby pushing the embedded box to move left and right, and realizing the left and right adjustment of the door.

[0011] The sliding block includes a wedge-shaped body with a sloping top and a flat bottom. One end of the wedge-shaped body is narrow, and the other end is wide. The wedge-shaped body is located on a boss, and the bottom flat surface is in contact with the top surface of the boss. At the same time, the top sloping surface is in contact with the bottom sloping surface of the wedge-shaped body. A U-shaped connecting plate is integrally formed at one end of the wide end of the wedge-shaped body. The mounting block in the second lifting structure is located inside the U-shaped connecting plate, and the two ends of the connecting shaft are perpendicularly connected to the inner wall of the U-shaped connecting plate. In the second lifting structure, the lifting adjustment rod drives the mounting block to move up and down, which enables the sliding block to slide left and right, thereby pushing the embedded box to move up and down and realizing the up and down adjustment of the door.

[0012] Preferably, the double-layer flange includes an upper flange and a lower flange, which are spaced apart and respectively fixedly fitted onto a capped bolt.

[0013] Preferably, the L-shaped mounting notch includes a mounting notch on the upright plate and a U-shaped notch on the adjusting base. The mounting notch and the U-shaped notch are connected. The capped bolt passes through the U-shaped notch, and the upper flange is secured to the upper side of the U-shaped notch through the mounting notch, while the lower flange is secured to the lower side of the U-shaped notch.

[0014] Preferably, the limiting buckle has an internal hexagonal groove that matches the fixing nut. Two baffles are provided at intervals on the left and right sides of the bottom opening of the internal hexagonal groove to support the fixing nut. The front and rear side walls of the internal hexagonal groove have symmetrical gaps to facilitate the installation of the fixing nut.

[0015] Preferably, two mating grooves are provided on the top wall of the pre-embedded box along the front-back direction. The two mating grooves correspond one-to-one with the two mounting blocks, and the mounting blocks can move up and down in the corresponding mating grooves.

[0016] Preferably, a reinforcing iron plate is provided between the adjusting base and the connecting piece, and the adjusting base, the reinforcing iron plate and the connecting piece are fixedly connected by bolts.

[0017] Preferably, the device further includes an upper hinge seat, an upper hinge shaft fixedly installed on the bottom surface of the upper hinge seat, and an upper track groove embedded in the upper frame of the door body. The upper hinge shaft is located in the upper track groove, and when the door body is rotated, the upper hinge shaft can move along the upper track groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention provides a refrigerator door adjustment device that can adjust the height of the door and also adjust the left and right tilt angle of the door to accommodate cabinet deformation or insufficient clearance, thus better realizing the embedded installation of the refrigerator. In addition, the door can be adjusted by turning the corresponding capped screw. Both users and after-sales personnel can operate it, which is convenient and quick. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] Furthermore, in the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1 to 3As shown, a preferred embodiment of the present invention provides a refrigerator door adjustment device. The device includes a pre-embedded box 1 located on the lower frame of the door, a lower hinge seat 2 located below the pre-embedded box 1, and the lower hinge seat 2 is fixedly installed on the refrigerator cabinet by bolts. The pre-embedded box 1 is equipped with: a wedge block 3, a lower hinge shaft 4, a connector 5, an adjustment base 6, a lifting structure, a sliding rod 7, and a sliding block 8.

[0038] like Figure 4 As shown, the wedge block 3 is fixedly installed on the top wall of the pre-embedded box 1, and the bottom of the wedge block 3 is a slope.

[0039] The lower hinge shaft 4 is vertically fixedly installed on the top surface of the lower hinge seat 2. The connecting piece 5 is provided with a lower track groove 9 that mates with the lower hinge shaft 4, such as... Figure 5 As shown, the lower hinge shaft 4 is located in the lower track groove 9, meaning that the connecting piece 5 is fitted onto the lower hinge shaft 4 via the lower track groove 9. When the connecting piece 5 is rotated, the lower hinge shaft 4 can move along the lower track groove 9. Specifically, the movement is a translational sliding motion, and not a fixed-axis rotation. The purpose is to ensure that the door does not exceed or slightly exceed the width of the refrigerator cabinet when opened. Of course, the matching structure between the lower hinge shaft and the lower track groove is existing technology and is not an innovation of this invention, so it will not be described in detail here.

[0040] Furthermore, a reinforcing rib 10 is provided at the end of the connector 5 away from the lower track groove 9 to enhance the overall strength of the connector 5.

[0041] like Figures 6-7 The bottom surface of the adjustable base 6 is provided with a limiting groove 11 that matches the lower track groove 9. Specifically, the limiting groove 11 protrudes upward and forms a boss 12 on the top surface of the adjustable base 6. The adjustable base 6 is fixedly installed on the connector 5, and the lower track groove 9 is located in the limiting groove 11. Symmetrical upright plates 13 are provided on the left and right sides of the top surface of the adjustable base 6. Each upright plate 13 has a through hole 14, and the two through holes 14 are arranged symmetrically. At the connection point between one of the upright plates 13 and the adjustable base 6, two L-shaped mounting notches are provided along the front-back direction. Specifically, the L-shaped mounting notches include a mounting notch 15 on the upright plate 13 and a U-shaped notch 16 on the adjustable base 6, and the mounting notch 15 and the U-shaped notch 16 are connected.

[0042] Furthermore, a reinforcing iron plate 17 is provided between the adjusting base 6 and the connecting piece 5, and the adjusting base 6, the reinforcing iron plate 17 and the connecting piece 5 are fixedly connected by bolts.

[0043] There are two sets of lifting structures, each corresponding to one of the two L-shaped mounting notches, such as... Figure 8As shown, the lifting structure includes a lifting adjustment rod 18, and an integrally formed mounting block 19 on the top of the lifting adjustment rod 18. The mounting block 19 is provided with an elongated through hole 20, which connects the front and rear sides of the mounting block 19. The elongated through hole 20 is arranged at an angle, and a connecting shaft 21 is provided in the elongated through hole 20. The connecting shaft 21 can slide along the length direction of the elongated through hole 20.

[0044] The bottom of the lifting adjustment rod 18 is provided with a blind hole 22, and a limit buckle is provided at the end of the blind hole 22. A fixing nut 23 is installed in the limit buckle. Specifically, as shown in the figure... Figure 9 As shown, the limiting buckle has an internal hexagonal socket 24 that matches the fixing nut 23, which is used to limit the rotation of the fixing nut 23. Two baffles 25 are provided at intervals on the left and right sides of the bottom opening of the internal hexagonal socket 24 to support the fixing nut 23. The front and rear side walls of the internal hexagonal socket 24 have symmetrical gaps 26 to facilitate the installation of the fixing nut 23. The specific operation is to pull the two baffles 25 outwards respectively. Since the front and rear side walls of the internal hexagonal socket 24 have gaps 26, the opening of the internal hexagonal socket 24 can be enlarged. Then, the fixing nut 23 is put into the internal hexagonal socket 24.

[0045] A capped screw 27 is threaded into the fixing nut 23. By rotating the capped screw 27, the end of the capped screw 27 can extend into the blind hole 22. A double-layer flange is fixedly fitted onto the capped screw 27 near the nut. Specifically, the double-layer flange includes an upper flange 28 and a lower flange 29, which are spaced apart and fixedly fitted onto the capped screw 27.

[0046] The double flange clip has an L-shaped mounting notch, specifically, as shown in the image. Figure 10 As shown, the capped screw 27 passes through the U-shaped notch 16 on the adjusting base 6, and the upper flange 28 passes through the mounting notch 15 on the vertical plate 13 and is locked on the upper side of the U-shaped notch 16, while the lower flange 29 is locked on the lower side of the U-shaped notch 16.

[0047] When the capped screw 27 is rotated, the double-layer flange rotates synchronously with the capped screw 27. Since the double-layer flange limits the capped screw 27, the capped screw 27 cannot move up and down in the vertical direction. Driven by the capped screw 27, the lifting adjustment rod 18 and the fixing nut 23 move up and down synchronously in the vertical direction.

[0048] Furthermore, two mating grooves 30 are provided on the top wall of the pre-embedded box 1 along the front-back direction. The two mating grooves 30 correspond one-to-one with the two mounting blocks 19. When the lifting adjustment rod 18 moves up and down in the vertical direction, it can drive the mounting block 19 to move up and down in the corresponding mating groove 30 to prevent displacement.

[0049] One end of the sliding rod 7 passes through the through hole 14 on the left vertical plate 13, and the other end passes through the through hole 14 on the right vertical plate 13, as shown. Figure 11 As shown, a strip-shaped mounting hole 31 is provided on the sliding rod 7. The mounting block 19 in the first lifting structure is located in the strip-shaped mounting hole 31, and the two ends of the corresponding connecting shaft 21 are perpendicularly and fixedly connected to the inner wall of the strip-shaped mounting hole 31. In the first lifting structure, the lifting adjustment rod 18 drives the mounting block 19 to move up and down, so that the connecting shaft 21 slides along the elongated through hole 20, and drives the sliding rod 7 to slide left and right, thereby pushing the embedded box 1 to move left and right, and finally realizing the left and right adjustment of the door 32.

[0050] like Figure 12 As shown, the sliding block 8 includes a wedge 33. The top of the wedge 33 is an inclined surface, the bottom is a flat surface, and one end of the left and right ends is a narrow end face and the other end is a wide end face. The wedge 33 is located on the boss 12, and the bottom flat surface is in contact with the top surface of the boss 12. The boss 12 supports the wedge 33. At the same time, the top inclined surface is in contact with the bottom inclined surface of the wedge block 3. When the bottom inclined surface of the wedge block 3 is in complete contact with the top inclined surface of the wedge 33, the two form a rectangle.

[0051] A U-shaped connecting plate 34 is integrally formed at one end of the wide end face of the wedge-shaped body 33. The mounting block 19 in the second lifting structure is located inside the U-shaped connecting plate 34, and the two ends of the connecting shaft 21 are vertically and fixedly connected to the inner wall surface of the U-shaped connecting plate 34. In the second lifting structure, the lifting adjustment rod 18 drives the mounting block 19 to move up and down, causing the connecting shaft 21 to slide along the elongated through hole 20, and driving the sliding block 8 to slide left and right. By changing the contact area between the bottom inclined surface of the wedge block 3 and the top inclined surface of the wedge-shaped body 33, the embedded box 1 is pushed up and down, ultimately realizing the up and down adjustment of the door body 32.

[0052] In addition, such as Figure 13 As shown, the device also includes an upper hinge seat 35 fixedly installed on the refrigerator cabinet body, an upper hinge shaft 36 fixedly installed on the bottom surface of the upper hinge seat 35, and an upper track groove 37 embedded in the upper frame of the door body. The upper hinge shaft 36 is located in the upper track groove 37. When the door body 32 is rotated, the upper hinge shaft 36 can move along the upper track groove 37, so that the door body 32 does not exceed or slightly exceeds the width of the refrigerator cabinet body when opened. Similarly, the cooperation structure between the upper hinge shaft 36 and the upper track groove 37 is prior art and not an innovation of this invention, and will not be described in detail here.

[0053] In summary, the refrigerator door adjustment device described in this embodiment of the invention can adjust the height of the door and also adjust the left and right tilt angle of the door to adapt to cabinet deformation or insufficient reserved space, thus better realizing the embedded installation of the refrigerator. In addition, the door can be adjusted by turning the corresponding capped screw, which can be operated by both users and after-sales personnel, making it convenient and quick.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
