Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a refrigeration device. Background Technology

[0002] The hydraulic feet use a lever-flipping structure to raise and lower the feet. However, since the lever structure has no limit, the lever bracket is prone to flipping outward during manufacturing or handling, causing the refrigerator to tilt forward and subsequent hydraulic foot adjustment to fail.

[0003] In view of this, it is necessary to provide a refrigeration device to solve the above-mentioned technical problems. Utility Model Content

[0005] As a further improvement of this utility model, the base plate also includes wing plates located on opposite sides of the through hole, and the limiting shaft is mounted on the wing plates; the adjusting member is rotatably mounted on the wing plates via a rotating shaft, the rotating shaft being located between the base foot and the driving part, and the arrangement direction of the base foot and the driving part intersecting the extension direction of the rotating shaft.

[0006] As a further improvement of this utility model, the limiting groove is located between the rotating shaft and the base.

[0007] As a further improvement of this utility model, the limiting groove is an arc-shaped groove with the rotating shaft as the center.

[0008] As a further improvement of this utility model, the travel of the hydraulic mechanism driving the drive unit is matched with the travel of the limiting shaft along the limiting groove.

[0009] As a further improvement of this utility model, the rotation angle range of the adjusting member is 13~28°.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0019] like Figures 1 to 10As shown, the refrigeration equipment provided by this utility model includes a base plate 10 and a plurality of foot assemblies 20 mounted on the base plate 10, which support the refrigeration equipment. The height of the foot assemblies 20 is adjustable, thereby adjusting the height of the refrigeration equipment or leveling the refrigeration equipment. The refrigeration equipment includes, but is not limited to, refrigerators, freezers, etc.

[0020] The base plate 10 has a through hole 11, wing plates 12 located on opposite sides of the through hole 11, and a limiting shaft 13 mounted on the wing plates 12. A portion of the foot assembly 20 passes through the through hole 11 and contacts the bearing surface, thereby supporting the refrigeration equipment. The wing plates 12 extend vertically upward from the edge of the through hole 11 for assembling the foot assembly 20. The limiting shaft 13 is installed between the two wing plates 12 and is used to limit the movement of the foot assembly 20.

[0021] The base assembly 20 includes a hydraulic mechanism 21 fixed to the top of the base plate 10, an adjusting member 22 rotatably mounted on the base plate 10, and a base 23 connected to the adjusting member 22. The base 23 at least partially passes through the through hole 11 and contacts the bearing surface to support the refrigeration equipment. The hydraulic mechanism 21 provides support for the adjusting member 22 and drives the adjusting member 22 to rotate, thereby adjusting the support height of the base 23 to achieve height adjustment or leveling of the refrigeration equipment.

[0022] Specifically, the hydraulic mechanism 21 includes a base 211 fixed to the top of the base plate 10, an outer shell 212 fixedly connected to the base 211, and an inner cylinder 213 movably disposed within the outer shell 212. The inner cylinder 213 can move up and down along the outer shell 212. A sealed oil cavity 214 is formed between the base 211, the outer shell 212, and the inner cylinder 213. The base 211 is provided with an oil delivery channel communicating with the sealed oil cavity 214.

[0023] The oil delivery channel is used to connect with the external oil delivery device or the hydraulic mechanism 21 on the other foot assembly 20. When the hydraulic medium in the external oil delivery device or other hydraulic mechanism 21 flows into the sealed oil chamber 214 from the oil delivery channel, the oil pressure in the sealed oil chamber 214 increases, pushing the inner cylinder 213 to move upward along the outer shell 212. The hydraulic mechanism 21 rises, thereby pushing the adjusting member 22 to rotate. When the hydraulic medium in the sealed oil chamber 214 flows out from the oil delivery channel to the external oil delivery device or other hydraulic mechanism 21, the oil pressure in the sealed oil chamber 214 decreases, the inner cylinder 213 moves downward along the outer shell 212, the hydraulic mechanism 21 lowers, and the adjusting member 22 rotates synchronously.

[0024] The adjusting member 22 has a limiting groove 221, a driving part 222 that abuts against the hydraulic mechanism 21, and a rotating shaft 223 rotatably connected to the wing plate 12. The limiting shaft 13 is located in the limiting groove 221, and the rotating shaft 223 is located between the base 23 and the driving part 222. The arrangement direction of the base 23 and the driving part 222 intersects the extension direction of the rotating shaft 223.

[0025] The adjusting member 22 is rotatably mounted on the wing plate 12 via the rotating shaft 223. The base 23 and the driving part 222 are located on both sides of the rotating shaft 223, respectively. It can be understood that the adjusting member 22 acts as a lever. When the oil pressure in the sealing oil chamber 214 changes, causing the inner cylinder 213 to move up and down along the outer shell 212, the driving part 222 moves up and down synchronously with the inner cylinder 213. The adjusting member 22 rotates around the rotating shaft 223, thereby adjusting the support height of the base 23.

[0026] The limiting groove 221 is located between the rotating shaft 223 and the base 23, that is, the limiting shaft 13 is located between the rotating shaft 223 and the base 23, thereby keeping the limiting shaft 13 away from the hydraulic mechanism 21 and preventing the limiting shaft 13 from affecting the lifting and lowering of the hydraulic structure 21.

[0027] During the process of adjusting the support height of the foot 23 by driving the adjusting member 22 to rotate through the hydraulic mechanism 21, the limiting shaft 13 moves along the limiting groove 221. When the limiting shaft 13 moves to the top of the limiting groove 221 and abuts against the inner wall of the limiting groove 221, the end of the adjusting member 22 with the foot 23 can no longer rotate downwards, and the foot 23 reaches its maximum support height. When the limiting shaft 13 moves to the bottom of the limiting groove 221 and abuts against the inner wall of the limiting groove 221, the end of the adjusting member 22 with the foot 23 can no longer rotate upwards, and the foot 23 is at its minimum support height.

[0028] The cooperation between the limiting shaft 13 and the limiting groove 221 restricts the rotation angle of the adjusting member 22. This prevents the adjusting member 22 from flipping outwards during the movement or handling of the refrigeration equipment. Excessive flipping of the adjusting member 22 would cause the drive unit 222 to rotate to the side of the rotating shaft 223 away from the hydraulic mechanism 21, resulting in a significant forward tilt of the refrigeration equipment that requires manual adjustment to return to its original position. Simultaneously, when the base 23 is adjusted to its minimum support height, the limiting shaft 13 and the rotating shaft 223 share the load, preventing deformation of the rotating shaft 223.

[0029] The limiting groove 221 is an arc-shaped groove with the rotating shaft 223 as the center. In this way, the limiting shaft 13 can move along the arc-shaped groove without interfering with the rotation of the adjusting member 22.

[0030] The hydraulic structure 21 drives the driving unit 22 to move at a distance that matches the travel distance of the limiting shaft 13 along the limiting groove 221. That is, when the hydraulic structure 21 rises and drives the adjusting member 22 to rotate, causing the foot 23 to reach its maximum support height, the limiting shaft 13 is located at the top of the limiting groove 221. When the hydraulic structure 21 lowers and the adjusting member 22 rotates synchronously, causing the foot 23 to reach its minimum support height, the limiting shaft 13 is located at the bottom of the limiting groove 221. Thus, the arrangement of the limiting groove 221 and the limiting shaft 13 does not restrict the adjustment range of the foot 23.

[0031] Under the constraints of the limiting groove 221 and the limiting shaft 13, the rotation angle of the adjusting member 22 ranges from 13° to 28°. The rotation angle of the adjusting member 22 is the angle between the adjusting member 22 and the horizontal line. When the hydraulic structure 21 is raised to its maximum stroke, the rotation angle of the adjusting member 22 is 28°, and the height of the refrigeration equipment is at its highest. When the hydraulic structure 21 is lowered to its minimum stroke, the rotation angle of the adjusting member 22 is 13°, and the height of the refrigeration equipment is at its lowest.

[0032] Of course, in other embodiments, the limiting groove 221 may be disposed between the rotating shaft 223 and the driving part 222, in which case the limiting shaft 13 is located between the rotating shaft 223 and the driving part 222.

[0033] The drive unit 222, under the action of the base 23, always maintains a resisting state against the hydraulic mechanism 21. The adjusting member 22 includes a base plate and side plates extending vertically downward from two opposite sides of the base plate. The drive unit 222 is a drive rod connected between the two side plates, and the drive rod is parallel to the rotating shaft 223. The drive rod abuts against the top of the inner cylinder 213. During the process of the inner cylinder 213 moving up and down along the outer shell 212 due to changes in oil pressure, the drive rod always maintains a resisting state against the inner cylinder 213.

[0034] The base 23 is connected to the connecting portion 224 of the adjusting member 22, and the connecting portion 224 is located at the end of the adjusting member 22 away from the driving portion 222. The base 23 is rotatably mounted to the connecting portion 224 via a pivot shaft.

[0035] Under normal conditions, the foot 23 is in contact with the bearing surface, and the connecting part 224 transmits the pressure to the driving part 222. The driving part 222 abuts against and applies pressure to the hydraulic mechanism 21. The oil pressure in the hydraulic mechanism 21 is the same as the pressure applied to the hydraulic mechanism 21 by the driving part 222. The hydraulic mechanism 21 supports the driving part 222 and keeps the adjusting member 22 fixed. The foot 23 is also fixed at the same time.

[0036] When the pressure on the foot 23 increases or the medium in the hydraulic mechanism 21 is lost, causing the oil pressure in the hydraulic mechanism 21 to decrease, the pressure applied to the hydraulic mechanism 21 by the drive unit 222 will be greater than the oil pressure in the hydraulic mechanism 21. The hydraulic mechanism 21 will contract, and the drive unit 222 will move in the contraction direction of the hydraulic mechanism 21. The adjusting member 22 will start to rotate, and the rotation of the adjusting member 22 will reduce the support height of the foot 23 until the oil pressure in the hydraulic mechanism 21 and the pressure applied to the hydraulic mechanism 21 by the drive unit 222 are equal again.

[0037] When the pressure on the foot 23 decreases or the medium flowing into the hydraulic mechanism 21 causes the oil pressure in the hydraulic mechanism 21 to increase, the pressure applied to the hydraulic mechanism 21 by the drive unit 222 will be less than the oil pressure in the hydraulic mechanism 21, the hydraulic mechanism 21 will rise, and the drive unit 222 will move in the direction of the rise of the hydraulic mechanism 21. The adjusting member 22 will start to rotate, and the rotation of the adjusting member 22 will increase the support height of the foot 23 until the oil pressure in the hydraulic mechanism 21 and the pressure applied to the hydraulic mechanism 21 by the drive unit 222 are once again equal.

[0038] In some embodiments, the arrangement direction of the foot 23 and the drive part 222 is perpendicular to the extension direction of the shaft 223.

[0039] The refrigeration equipment also includes a hydraulic adjustment component 30, which is connected to the hydraulic mechanism 21 to realize the flow of hydraulic medium between the hydraulic adjustment component 30 and the hydraulic mechanism 21, thereby realizing the adjustment of the support height of the foot assembly 20.

[0040] When the hydraulic medium in the hydraulic regulating assembly 30 flows into the hydraulic mechanism 21, the oil pressure in the sealed oil chamber 214 increases, thereby pushing the inner cylinder 213 upward along the outer shell 212, and the hydraulic mechanism 21 rises. When the hydraulic medium in the hydraulic mechanism 21 flows into the hydraulic regulating assembly 30, the inner cylinder 213 moves downward along the outer shell 212, and the hydraulic mechanism 21 lowers.

[0041] The hydraulic regulating assembly 30 includes a reservoir 31, an oil bladder 32 located in the reservoir 31 for storing hydraulic medium, a first oil pipe 33 connecting the oil bladder 32 and the hydraulic mechanism 21, and a pusher 34 threadedly connected to the reservoir 31 and applying pressure to the oil bladder 32.

[0042] When it is necessary to increase the support height of the foot assembly 20, the pusher 34 is rotated to move into the reservoir 31. The pusher 34 squeezes the oil bladder 32, so that the hydraulic medium in the oil bladder 32 flows into the hydraulic mechanism 21 from the first oil pipe 33. The oil pressure in the sealed oil chamber 214 increases, thereby pushing the inner cylinder 213 to move upward along the outer shell 212, and the hydraulic mechanism 21 rises.

[0043] When it is necessary to lower the support height of the foot assembly 20, the pusher 34 is rotated to move the pusher 34 outward from the reservoir 31. The pressure of the pusher 34 on the oil bladder 32 decreases, and the oil pressure in the sealing oil chamber 214 is greater than the oil pressure in the oil bladder 32. As a result, the hydraulic medium in the sealing oil chamber 214 flows into the oil bladder 32 from the first oil pipe 33, and the oil pressure in the sealing oil chamber 214 increases. The inner cylinder 213 moves downward along the outer shell 212, and the hydraulic mechanism 21 is lowered.

[0044] To prevent the pusher 34 from separating from the liquid storage tank 31 due to excessive adjustment, an anti-detachment component 341 is provided at the end of the pusher 34 located inside the liquid storage tank 31. The outer diameter of the anti-detachment component 341 is larger than the diameter of the threaded hole on the liquid storage tank 31, thereby effectively preventing the pusher 34 from falling off. The limiting component 341 can be a retaining spring or the like.

[0045] The end of the pusher 34 away from the anti-detachment member 341 is also provided with a drive part 342. The drive part 342 is used to connect with an external drive rod. The drive rod is inserted into the drive part 342, thereby driving the pusher 34 to rotate. The drive part 342 is a non-circular hole.

[0046] The hydraulic adjustment assembly 30 also includes a fixing plate 35, and the liquid storage tank 31 is fixedly installed on the base plate 10 through the fixing plate 35.

[0047] In some embodiments, two foot assemblies 20 are spaced apart on the base plate 10, and the refrigeration device further includes a second oil pipe 40 connecting the two foot assemblies 21. Thus, hydraulic fluid can flow between the two foot assemblies 20, enabling adaptive leveling of the refrigeration device.

[0048] The two foot assemblies 20 can be located at the rear of the refrigeration equipment, and the hydraulic adjustment assembly 30 can be located at the front of the refrigeration equipment, or the drive rod can be extended to the front of the refrigeration equipment. In this way, the height adjustment of the two rear foot assemblies 20 can be completed from the front of the refrigeration equipment, which is convenient and quick.

[0049] In summary, this utility model can limit the rotation angle of the adjusting member 22 by the cooperation of the limiting shaft 13 and the limiting groove 221. In this way, it can prevent the adjusting member 22 from flipping outward, that is, the adjusting member 22 from overturning, causing the driving part 222 to rotate to the side of the rotating shaft 223 away from the hydraulic mechanism 21, resulting in a large degree of forward tilting of the subsequent refrigeration equipment and the failure of adjustment.

[0050] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for 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.

[0051] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
