[0040] In this embodiment, the mounting seat 4 includes a mounting body 41 at the bottom, a first connecting column 42 vertically connected to the mounting body 41, and a first connecting rod 51 and a second connecting rod 52 are respectively rotatably connected to the first connecting column 42 through their right ends; the mounting bracket 9 includes a second connecting column 91 suspended above the mounting body 41, the second connecting column 91 is vertically arranged and parallel to the first connecting column 42, and the first connecting rod 51 and the second connecting rod 52 are respectively rotatably connected to the second connecting column 91 through their left ends. Through the above structure, the first connecting rod 51, the second connecting rod 52, the first connecting column 42 and the second connecting column 91 form a set of parallelograms.

[0041] The operating rod 6 includes a first rod body 61 parallel to the first direction, and at least two second rod bodies 62 respectively connected to the first rod body 61 and perpendicular to the first direction.

[0042] The operating rod 6 has a first position and a second position. The limiting member 7 can be used to limit the operating rod 6 at the first position and the second position respectively. The limiting member 7 is provided with a guide groove 71 which is inclined along the up and down directions and perpendicular to the first direction. The guide groove 71 includes a first end 711 and a second end 712. In this embodiment, the guide groove 71 is inclined downward in a direction close to the mounting bracket 9, and the first end 711 is higher than the second end 712.

[0043] in:

[0044] See also Figure 1-2 As shown, when the operating lever 6 is in the first position, the first rod body 61 is located in the first end portion 711, and the second rod body 62 is arranged downwardly in a direction close to the mounting bracket 9, and the second rod body 62 is perpendicular to the first connecting rod 51, forming a self-locking structure, and the bearing surface of the first end portion 711 for bearing the first rod body 61 is perpendicular to the second rod body 62, further ensuring the stability of the self-locking structure;

[0045] See also Figure 3-4 As shown, when the operating lever 6 is in the second position, the first rod body 61 is located in the second end portion 712, and the second rod body 62 is inclined in the direction close to the mounting bracket 9. The second rod body 62 is perpendicular to the first connecting rod 51 to form a self-locking structure, and the bearing surface of the second end portion 712 for supporting the first rod body 61 is perpendicular to the second rod body 62, further ensuring the stability of the self-locking structure.

[0046] See also Figure 4 As shown, in this embodiment, the upper end of the guide groove 71 is bent downward to the right to form a bent portion for carrying the first rod body 61, and the bent portion is the first end 711. By setting the bent first end 711, when the operating rod 6 is in the first position, the first end 711 can stably limit the first rod body 61.

[0047] See also Figure 2 , Figure 4 As shown, when the operating rod 6 is in the first position and the second position respectively, one end of the first connecting rod 51 for connecting the mounting bracket 9 is located on the same vertical line. Through this arrangement, it can be ensured that the tube body 21 and the nozzle 3 are still located directly below the conveying track of the bottle 1 after adjusting the height.

[0048] See also Figure 2 As shown, when the operating rod 6 is in the first position, the nozzle 3 is relatively high and is used to cool the shorter bottle 1 (ie, the bottle with a higher bottom); see Figure 4 As shown, when the operating lever 6 is in the second position, the nozzle 3 is in a relatively low position, and is used to cool a longer bottle 1 (ie, a bottle with a lower bottom).

[0049] In this embodiment, there is a pair of connecting rod assemblies 5 and a pair of limiting members 7, the pair of limiting members 7 are arranged at intervals along the first direction and are located between the pair of connecting rod assemblies 5, the length of the first rod body 61 is longer than the distance between the pair of limiting members 7, and the two second rod bodies 62 are respectively arranged on the outside of the pair of limiting members 7.

[0050] Obviously, the lifting mechanism can also be used in other places in the bottle blowing machine where height adjustment is required, and is not limited to the application in the cooling device of this embodiment.

[0051] The working process of this embodiment is described in detail below:

[0052] When the bottle 1 to be cooled is shorter, the operating rod 6 is slid upward along the groove direction of the guide groove 71, so that the left ends of the first connecting rod 51 and the second connecting rod 52 rotate and rise around their right ends respectively, until the first rod body 61 enters the upper rest position (i.e., enters the first end portion 711), at which time the first connecting rod 51 and the second connecting rod 52 rotate to the right position and are perpendicular to the second rod body 62;

[0053] When the bottle 1 to be cooled is long, the operating rod 6 is slid downward along the guide groove 71, so that the left ends of the first connecting rod 51 and the second connecting rod 52 rotate around their right ends and descend respectively until the first rod body 61 enters the lower rest position (i.e., enters the second end 712). At this time, the first connecting rod 51 and the second connecting rod 52 rotate into place and are perpendicular to the second rod body 62.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
