Detailed Embodiments

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts shall fall within the protection scope of the present utility model.

[0015] A refrigeration unit bottom plate installation and adjustment device, such as Figure 1 , 2As shown in FIGS. 3 and 4, it includes a bottom plate 1. A placement plate 2 is provided on the bottom plate 1. The placement plate 2 is provided with several waist-shaped holes 3. On both sides of the bottom plate 1, screw rods 4 are rotatably installed respectively. There are several screw rods 4. The outer circumferences on both sides of the screw rod 4 are rotatably connected to the inner holes of the shaft seats through bearings. The shaft seats are fixedly installed on the bottom plate 1. Two screw rods 4 form a group, and the screw rods 4 in the same group are symmetrically distributed left and right. In this embodiment, there are two groups of screw rods 4, and they are symmetrically distributed front and back. A nut 5 is threadedly fitted on the outer circumference of the screw rod 4. One end of a first connecting rod 6 is rotatably connected to the nut 5 through a hinge shaft. The other end of the first connecting rod 6 is hinged to the bottom side of the placement plate 2 through a hinge shaft. A first sliding rod 7 is fixedly installed on the bottom plate 1. The outer circumferences on both sides of the first sliding rod 7 are respectively slidably installed with first sliding sleeves 8. The two first sliding sleeves 8 are symmetrically distributed front and back. The first sliding sleeve 8 can only move back and forth along the first sliding rod 7. The first sliding rod 7 is perpendicular to the axis of the screw rod 4. One end of a second connecting rod 9 is respectively hinged to the first sliding sleeve 8. The other end of the second connecting rod 9 is hinged to a second sliding sleeve 10. The second sliding sleeve 10 is slidably installed on a second sliding rod 11. The second sliding rods 11 are respectively fixedly installed on the placement plate 2. The two second sliding rods 11 and the second sliding sleeves 10 are symmetrically distributed front and back. The structure of the utility model is simple and ingenious. It can not only adjust the height of the refrigeration unit, but also adjust the angle of the refrigeration unit. When the installation ground is uneven, by adjusting the angle of the placement plate 2, the refrigeration unit can be kept horizontal, which is applicable to different installation environments, has simple operation, can meet the actual needs, and is suitable for popularization. When using the utility model, place the refrigeration unit on the placement plate 2, and install the refrigeration unit on the placement plate 2 through the cooperation of bolts and the waist-shaped holes 3. When it is necessary to adjust the height of the refrigeration unit, rotate the screw rods 4 synchronously. Several nuts 5 move towards each other. At this time, the nut 5 drives the first connecting rod 6 to move. The first connecting rod 6 rotates along the hinge shaft on the nut 5, and at the same time, the first connecting rod 6 rotates along the hinge shaft connected to the placement plate 2. At this time, several first connecting rods 6 drive the placement plate 2 to move upward. At the same time, the placement plate 2 drives the first sliding sleeve 8 to slide along the corresponding first sliding rod 7 through the second sliding sleeve 10 and the second connecting rod 9. When it is necessary to adjust the angle of the refrigeration unit and the placement plate 2, rotate the left and right screw rods 4 to make the left and right screw rods 4 rotate in the opposite direction, so that the nuts 5 on both sides move in the same direction along the screw rods 4. One side of the first connecting rod 6 drives one side of the placement plate 2 to move upward, and the other side of the first connecting rod 6 drives the other side of the placement plate 2 to move downward. The placement plate 2 drives the first sliding sleeve 8 to slide along the first sliding rod 7 through the second connecting rod 9. At this time, the placement plate 2 drives the second sliding rod 11 to move upward. At this time, under the action of the second connecting rod 9, the second sliding sleeve 10 can only move upward, and the second sliding rod 11 rotates in the second sliding sleeve 10, and the angle of the placement plate 2 and the refrigeration unit changes. When the ground is uneven, the refrigeration unit can be kept horizontal by adjusting the angle of the placement plate 2, and the refrigeration unit is installed.

[0016] Specifically, as shown in the figure, the outer ends of the lead screws 4 in this embodiment are respectively fixedly installed with first handwheels 20. It is more convenient and labor-saving to rotate the lead screws 4 through the first handwheels 20.

[0017] Specifically, as shown in the figure, an annular plate 30 is slidably installed on the outer periphery of the nut 5 in this embodiment. The annular plate 30 can only slide left and right along the nut 5. One end of the first connecting rod 6 is hinged to the annular plate 30. A first baffle 31 is fixedly installed on the outer side of the nut 5, and a second baffle 32 is fixedly installed on the inner side of the nut 5. Both the first baffle 31 and the second baffle 32 are larger than the size of the annular plate 30, which can prevent the annular plate 30 from sliding off the nut 5. The annular plate 30 is connected to the first baffle 31 through a spring 33. The spring 33 is sleeved on the outer periphery of the nut 5. One end of the spring 33 is fixedly connected to one side of the annular plate 30, and the other end of the spring 33 is fixedly connected to one side of the first baffle 31. When the refrigeration unit is placed on the placement plate 2 or the placement plate 2 is subjected to an impact, at this time, the spring 33 can be continuously compressed and stretched to buffer the refrigeration unit.

[0018] Furthermore, as shown in the figure, a threaded hole 40 is opened on the first baffle 31 in this embodiment. A threaded rod 41 is installed in the threaded hole 40 in a threaded fit manner. A fixing block 42 is fixedly installed at the bottom of the annular plate 30. One end of the threaded rod 41 is in abutting contact with the fixing block 42, and a second handwheel 43 is fixedly installed at the other end of the threaded rod 41. By adjusting the threaded rod 41, the buffering degree of the spring 33 can be adjusted. When buffering is not required, the threaded rod 41 is screwed by the second handwheel 43. The threaded rod 41 pushes the fixing block 42 and the annular plate 30 close to the second baffle 32 until the annular plate 30 is in abutting contact with the second baffle 32, and the spring 33 is stretched. At this time, the annular plate 30 cannot move along the nut 5 and cannot buffer the refrigeration unit and the placement plate 2.

[0019] Even further, as shown in the figure, sliders 50 are respectively fixedly installed on the first sliding sleeves 8 in this embodiment. Corresponding sliding grooves 51 are opened on the bottom plate 1 for the sliders 50. The sliders 50 are slidably installed in the sliding grooves 51. When the first sliding sleeves 8 slide along the first sliding rods 7, the sliders 50 slide in the sliding grooves 51 along with the first sliding sleeves 8, which can limit the first sliding sleeves 8 and prevent the first sliding sleeves 8 from rotating.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
