[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a layered fresh milk barrel placement rack for a fresh milk cold storage, including a base 1, with wedge-shaped support columns 2 fixedly connected to one of the diagonal corners of the base 1. The width of the wedge-shaped support columns 2 is smaller at the top and larger at the bottom, and the diagonal sides of the wedge-shaped support columns 2 are arranged opposite each other. Square support columns 3 are fixedly connected to the other diagonal corner of the base 1. Multiple placement plates 4 are movably arranged between the wedge-shaped support column 2 and the square support column 3. The lower end of the placement plate 4 is provided with a wedge-shaped groove 43 corresponding to the position between the wedge-shaped support columns 2. Wedge-shaped blocks 5 are symmetrically arranged on the wedge groove 43. One end of the wedge block 5 is provided with an inclined part 51, which is arranged to abut against the inclined side of the wedge-shaped support column 2. The wedge-shaped support columns 2 are threaded together by a bidirectional lead screw 6 located in the wedge-shaped groove 43, and a rotating head 7 is provided in the middle of the bidirectional lead screw 6.

[0019] Furthermore, an adjustment groove 41 is provided through one of the diagonally opposite corners of the base 1, and the wedge-shaped support column 2 passes through the adjustment groove 41 accordingly, with the length of the adjustment groove 41 being greater than the width of the wedge-shaped support column 2. By setting the length of the adjustment groove 41 to be greater than the width of the wedge-shaped support column 2, it is convenient to meet the width requirement of the portion of the wedge-shaped support column 2 passing through the adjustment groove 41 when the placement plate 4 moves up and down to adjust the spacing.

[0020] Furthermore, square grooves 42 are provided through the other diagonal corner of the base 1, and square support columns 3 are fitted and pass through the square grooves 42.

[0021] Furthermore, the rotating head 7 has nuts 71 at both ends. The rotating head 7 can be rotated manually or by using a wrench or other tools to rotate the nuts 71, thereby driving the rotation of the bidirectional lead screw 6, which in turn drives the wedge block 5 to move synchronously along the wedge groove 43. The inclined part 51 at the end of the wedge block 5 abuts against the inclined side of the wedge support column 2 to lock the placement plate 4.

[0022] Furthermore, the bidirectional lead screw 6 is symmetrically connected with bearing seats 72 that are fixedly connected to the wedge groove 43. The bearing seats 72 provide limiting support for the bidirectional lead screw 6.

[0023] Specifically, first, adjust the height according to the height of the fresh milk bucket to meet the placement height. During the upward adjustment process of the placement plate 4, it can be manually lifted. Since the width of the wedge support column 2 is smaller at the top and larger at the bottom, the inclined part 51 will disengage from the inclined side of the wedge support column 2 during the lifting process. Then, manually adjust by rotating the head 7 or by using a tool through the nut part 71 to realize the rotation of the bidirectional screw 6. The bidirectional screw 6 is threadedly connected to the two wedge blocks 5, which drives the two wedge blocks 5 to move away from each other, so that the inclined part 51 at the end of the wedge block 5 abuts against the inclined side of the wedge support column 2, thereby locking the placement plate 4. The process of moving the placement plate 4 downwards requires first reversing the operation (as above) to rotate the bidirectional lead screw 6, which drives the two wedge blocks 5 to move closer to each other, disengaging the inclined part 51 at the end of the wedge block 5 from the inclined side of the wedge support column 2. After the distance is adjusted, the same operation as above is used to lock it. This utility model has a simple structure and is easy to operate, which can realize the stepless adjustment of the distance between the placement plates 4.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
