[0025] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0026] like Figures 1 to 6 As shown, the refrigerator provided by the present invention includes a housing 100, a rehydrator 200 located in the housing 100, a hydraulic foot 300 supporting the housing 100, and an adjusting rod 400 for controlling the rehydrator 200 so that the hydraulic medium flows between the rehydrator 200 and the hydraulic foot 300. The rehydrator 200 and the hydraulic foot 300 are connected, and the hydraulic media inside the two can flow to each other. The adjusting rod 400 is used to drive the hydraulic medium to flow between the rehydrator 200 and the hydraulic foot 300, thereby raising or leveling the housing 100.

[0027] The box body 100 includes a bottom plate 101, a rear cover plate 102, and a press chamber 103 formed by the bottom plate 101 and the rear cover plate 102. The press chamber 103 is located on the rear side of the box body 100, and the fluid replenisher 200 is located in the press chamber 103, thereby facilitating the installation of the fluid replenisher 200 without occupying other space in the box body 100.

[0028] Furthermore, a second through hole 102 a is formed on the rear cover 102 . The second through hole 102 a is used to install the adjustment rod 400 . The adjustment rod 400 passes through the second through hole 102 a to control the fluid dispenser 200 .

[0029] Specifically, the rear cover plate 102 includes a top plate 102b located above the bottom plate 101 and parallel to the bottom plate 101, and a side plate 102c connecting the bottom plate 101 and the top plate 102a. The side plate 102c is arranged at an angle and extends forward and downward from the front end of the top plate 102a to connect to the bottom plate 101. The first through hole 102a is opened on the side plate 102c.

[0030] The box body 100 further includes a lower front beam 104 having a first through hole 104a formed thereon. The first through hole 104a is used to install the adjustment rod 400. The adjustment rod 400 sequentially passes through the first through hole 104a on the lower front beam 104 and the second through hole 102a on the side plate 102c.

[0031] The fluid dispensing device 200 includes a housing 201, an oil bladder 202 located within the housing 201, the oil bladder 202 storing hydraulic medium, an inner cylinder 203 movably mounted within the housing 201, the inner cylinder 203 abutting against the oil bladder 202, an adjusting bolt 204 rotatably mounted on the housing 201, the adjusting bolt 204 extending from the outside of the housing 201 to the inside of the housing 201 and abutting against the inner cylinder 201, and the oil bladder 202 and the adjusting bolt 204 are respectively located on either side of the inner cylinder 203.

[0032] The fluid infuser 200 further includes an oil pipe interface 205 communicating with the oil bag 202 , and the hydraulic foot 300 is connected to the oil pipe interface 205 via an oil pipe.

[0033] Under normal conditions, the oil pressure in the oil bladder 202 is the same as the oil pressure in the hydraulic footing 300, and the hydraulic medium stops flowing, maintaining equilibrium. When the adjusting bolt 204 is rotated so that it enters the housing 201, the adjusting bolt 204 pushes the inner cylinder 203 toward the oil bladder 202, thereby squeezing the oil bladder 202 and increasing the oil pressure in the oil bladder 202. The hydraulic medium in the oil bladder 202 then flows through the oil pipe into the hydraulic footing 300, which is connected to the oil bladder 202, thereby raising the hydraulic footing 300 until the oil pressure in the oil bladder 202 becomes the same as that in the hydraulic footing 300.

[0034] When the adjusting bolt 204 is rotated so as to move the adjusting bolt 204 in a direction away from the inner cylinder 203, the pressure of the inner cylinder 203 on the oil bladder 202 is reduced, and the oil pressure in the oil bladder 202 is reduced, so that the hydraulic medium in the hydraulic foot 300 enters the oil bladder 202 connected to the hydraulic foot 300 through the oil pipe, thereby lowering the hydraulic foot 300 until the oil pressure in the oil bladder 202 is maintained the same as that in the hydraulic foot 300.

[0035] The hydraulic foot 300 is used to support the box body 100 and realize the height adjustment or leveling of the box body 100 through the circulation of hydraulic medium between the fluid replenisher 200 and the hydraulic foot 300.

[0036] In this embodiment, two sets of hydraulic feet 300 are provided, spaced apart on the rear side of the housing 100. The fluid infuser 200 also includes two sets of oil pipe connections 205, each connected to the two sets of hydraulic feet 300. This allows hydraulic medium to be simultaneously injected into both sets of hydraulic feet 300 or for the hydraulic medium in both sets of hydraulic feet 300 to flow back into the fluid infuser 200. The two sets of hydraulic feet 300 can also be connected via an oil pipe, allowing for the mutual flow of hydraulic medium between them and achieving self-balancing. Specifically, the hydraulic medium is hydraulic oil.

[0037] The adjusting rod 400 includes a control part for controlling the rehydrator 200 so that the hydraulic medium flows between the rehydrator 200 and the hydraulic foot 300, and an operating part located on the front side of the box body 100. By operating the operating part at the front of the box body 100, the control part can be controlled to adjust the height of the hydraulic foot 300, thereby solving the problem of adjusting the rear foot of the built-in refrigerator. After pushing the refrigerator in, the rear foot can be adjusted directly from the front without repeatedly dragging the refrigerator out for adjustment. The installation efficiency and experience can be greatly improved.

[0038] Furthermore, the adjustment rod 400 includes an outer tube 401 and an inner rod 402 rotatably mounted within the outer tube 401. The control unit and the operating unit are located at opposite axial ends of the inner rod 402. In this embodiment, the control unit drives the adjustment bolt 204 of the fluid infuser 200 to rotate, thereby driving the hydraulic medium to flow between the fluid infuser 200 and the hydraulic foot 300.

[0039] The outer cylinder 401 extends from the front side of the box body 100 through the first through hole 104a on the lower front beam 104 and the second through hole 102a on the side plate 102c in sequence to the position of the liquid dispensing device 200. The outer cylinder 401 forms an independent installation space in the box body 100 to install the inner rod 402. The outer cylinder 401 isolates the inner rod 402 from the foam layer in the box body 100, so that the inner rod 402 is not affected by the foam layer during rotation, and can also effectively avoid damage to the foam layer during the rotation of the inner rod 402.

[0040] Preferably, the end of the outer cylinder 401 away from the infusion device 200 is flush with the lower front beam 104, that is, the front end of the outer cylinder 401 is flush with the lower front beam 104, so that the outer cylinder 401 does not protrude from the box body 100, ensuring the beauty of the box body 100.

[0041] Furthermore, a sealing ring 401a is provided on the outer wall of the outer cylinder 401 to seal the second through hole 102a. The sealing ring 401a is in contact with the side plate 102c. The radius of the sealing ring 401a is greater than the radius of the second through hole 102a, so that the second through hole 102a can be completely blocked, thereby preventing the second through hole 102a from being blocked by the foaming material or even allowing the foaming material to enter the press chamber 103 from the second through hole 102a.

[0042] A limit ring 401b is provided on the inner wall of the outer cylinder 401, and an anti-slip ring 402a is provided on the inner rod 402. The anti-slip ring 402a is located on the side of the limit ring 401b facing the insufflator 200. The inner diameter of the limit ring 401b is larger than the radius of the inner rod 402 and smaller than the radius of the anti-slip ring 402a. The cooperation between the limit ring 401b and the anti-slip ring 402a effectively prevents the inner rod 402 from falling off the front end of the outer cylinder 401.

[0043] The control portion is provided with an adjustment hole 402b adapted to the adjustment bolt 204, and the end of the adjustment bolt 204 away from the inner cylinder 203 is located in the adjustment hole 402b, so that the adjustment bolt 204 is driven to rotate by rotating the inner rod 402, thereby adjusting the oil pressure in the oil bag 202, so that the hydraulic medium in the hydraulic base 300 flows into the oil bag 202 or the hydraulic medium in the oil bag 202 flows into the hydraulic base 300.

[0044] It should be noted that during the rotation of the inner rod 402, the inner rod 403 remains axially aligned, i.e., the adjustment bolt 204 moves along the adjustment hole 402b, thereby ensuring that the operating portion of the inner rod 402 remains stationary. This prevents the operating portion from protruding from the outer tube 401, thereby affecting the aesthetics of the housing 100, and from being excessively retracted into the outer tube 401, thereby affecting the next adjustment. Preferably, a plug can be added to the front end of the outer tube 401 to conceal the inner rod 402 when not in use, thereby enhancing safety and aesthetics.

[0045] Furthermore, the operating portion is a rotating head 402c, which is a non-circular component, so that the inner rod 402 can be rotated by an external wrench or other tool. In this embodiment, the rotating head 402c is a hexagonal structure, and the inner rod 402 can be rotated by manual or electric tools.

[0046] In summary, by rotating the adjusting rod 400, the hydraulic medium is driven to flow between the fluid infuser 200 and the hydraulic foot 300, thereby raising or leveling the box body 100. For the hydraulic foot 300 located on the rear side of the box body 100, the adjustment can be completed by extending the adjusting rod 400 to the front side of the box body 100, which is convenient and quick.

[0047] It should be understood that although this specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0048] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent embodiments or changes that do not depart from the technical spirit of the present invention should be included in the scope of protection of the present invention.
