[0065] See also Figures 6 to 11 As shown, in some embodiments, the first clamping position 33 has an opening on one side facing the mounting bracket 4. At the same time, a first cover 36 is provided at the first clamping position 33, and the first cover 36 is provided at the opening of the first clamping position 33, so that the push switch 34 can be encapsulated in the first clamping position 33 through the first cover 36.

[0066] See also Figures 8 to 13 As shown, in some embodiments, a compression spring 45 is provided in the second clamping position 43, one end of the compression spring 45 abuts against the inner wall of the second clamping position 43, and the other end of the compression spring 45 abuts against the clamping member 44, and the compression spring 45 can drive the clamping member 44 to move toward the outside of the second clamping position 43, so that the clamping member 44 can protrude out of the second clamping position 43. Therefore, when the lifting rib 3 is installed on the mounting bracket 4, the second clamping position 43 is directly connected to the first clamping position 33, so the compression spring 45 can drive the clamping member 44 to protrude out of the second clamping position 43, and enable the clamping member 44 to extend into the first clamping position 33, as shown in FIG. Figure 8 In the state shown, the mounting bracket 4 can be clamped with the lifting rib 3 through the clamping piece 44 to fix the lifting rib 3 on the mounting bracket 4.

[0067] In some embodiments, the compression spring 45 is sleeved on the outer periphery of the clamp 44, and the end of the compression spring 45 close to the first clamp position 33 abuts against the outer wall of the clamp 44, and the end of the compression spring 45 away from the first clamp position 33 abuts against the inner wall of the second clamp position 43, thereby enabling the compression spring 45 to drive the clamp 44 to move toward the outer end of the second clamp position 43 and toward the inside of the first clamp position 33.

[0068] See also Figures 8 to 13 As shown, in some embodiments, the second clamping position 43 is open on one side facing the lifting rib 3. At the same time, a second cover 46 is provided at the second clamping position 43, and the second cover 46 is provided at the opening of the second clamping position 43, so that the clamping member 44 can be encapsulated in the second clamping position 43 through the second cover 46.

[0069] See also Figures 6 to 13As shown, in some embodiments, the first clamping position 33 is provided at the side edge of the lifting rib 3 close to the inner wall of the inner tube 22, and at the same time, the second clamping position 43 is provided at the side edge of the mounting bracket 4 close to the first clamping position 33. Therefore, when the lifting rib 3 assembly is installed and covered on the mounting bracket 4, the first clamping position 33 can be located on one side of the second clamping position 43, thereby facilitating the second clamping position 43 to be directly connected with the first clamping position 33, so that the clamping member 44 can smoothly protrude from the second clamping position 43 and extend into the first clamping position 33.

[0070] In some embodiments, there are two first clamping positions 33, and the two first clamping positions 33 are respectively arranged at the side edges of the opposite sides of the lifting rib 3, that is, the two first clamping positions 33 are respectively arranged at the side edges of the first lifting wall 31 and the second lifting wall 32 close to the inner wall of the inner container. At the same time, there are two second clamping positions 43, and the two second clamping positions 43 are respectively arranged at the side edges of the opposite sides of the mounting bracket 4. When the lifting rib 3 is installed on the mounting bracket 4, the two first clamping positions 33 and the two second clamping positions 43 are arranged one by one, so that the opposite sides of the lifting rib 3 can be clamped on the mounting bracket 4, thereby improving the stability of the connection between the lifting rib 3 and the mounting bracket 4.

[0071] In some embodiments, the two first engaging positions 33 are arranged at the side edges of the two opposite sides of the lifting rib 3 in a left-right relative manner, and correspondingly, the two second engaging positions 43 are arranged at the side edges of the two opposite sides of the mounting bracket 4 in a left-right relative manner. The user can press the push switches 34 in the two first engaging positions 33 toward each other, so that the two push switches 34 are moved toward each other, and then the engaging members 44 in the two second engaging positions 43 respectively withdraw from the corresponding first engaging positions 33, so that the lifting rib 3 is smoothly separated from the mounting bracket 4, and then the lifting rib 3 can be quickly and easily removed from the mounting bracket 4, thereby improving the convenience of installing and removing the lifting rib 3.

[0072] See also Figures 6 to 13 As shown, in some embodiments, a first clamping portion 37 is provided on the side of the lifting rib 3 facing the mounting bracket 4. At the same time, a second clamping portion 47 is convexly provided on the side edge of the mounting bracket 4 and arranged opposite to the first clamping portion 37, and the second clamping portion 47 is used to be mutually clamped and matched with the first clamping portion 37. When the lifting rib 3 is installed on the mounting bracket 4, the first clamping portion 37 can be clamped on the side wall of the second clamping portion 47 away from the lifting rib 3, further fixing the lifting rib 3 on the mounting bracket 4.

[0073] In some embodiments, the first clamping portion 37 and the first clamping position 33 are arranged at intervals along the extending direction of the side edge of the lifting rib 3. Correspondingly, the second clamping portion 47 and the second clamping position 43 are arranged at intervals along the extending direction of the side edge of the mounting bracket 4. When the lifting rib 3 is installed and covered on the mounting bracket 4, the lifting rib 3 can be slid relative to the mounting bracket 4 along the axial direction of the inner cylinder 22, so that the first clamping position 33 and the second clamping position 43 are gradually connected to each other, so that the clamping member 44 in the second clamping position 43 can smoothly extend into and clamp into the first clamping position 33, and the first clamping portion 37 can be smoothly clamped on the second clamping portion 47. When the push switch 34 is pressed, the push switch 34 can squeeze the clamping part 44, causing the clamping part 44 to withdraw from the first clamping position 33. At this time, the first clamping part 37 can be separated from the second clamping part 47 by sliding the lifting rib 3 in the opposite direction, thereby separating the lifting rib 3 from the mounting bracket 4 and removing the lifting rib 3 from the mounting bracket 4.

[0074] In some embodiments, the lifting rib 3 is provided with a plurality of first clamping parts 37, which are divided into two groups. The two groups of first clamping parts 37 are respectively provided at the edges of the lifting rib 3 on opposite sides, that is, the two groups of first clamping parts 37 are respectively provided at the side edges of the first lifting wall 31 and the second lifting wall 32 close to the inner wall of the inner tank. At the same time, the mounting bracket 4 is provided with a plurality of second clamping parts 47, which are divided into two groups. The two groups of second clamping parts 47 are respectively provided at the edges of the mounting bracket 4 on opposite sides.

[0075] The two groups of first clamping parts 37 include a plurality of first clamping parts 37, which are arranged at intervals along the extending direction of the side edges of the first lifting wall 31 and the second lifting wall 32. The two groups of second clamping parts 47 include a plurality of second clamping parts 47, which are arranged at intervals along the extending direction of the opposite side edges of the mounting bracket 4. The two groups of first clamping parts 37 and the two groups of second clamping parts 47 are arranged one by one.

[0076] It should be noted that, in some other embodiments, the number and position of the first clamping portions 37 and the second clamping portions 47 can be adjusted as needed, and are not limited here.
