[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] like Figure 1-6 As shown, a tea drying rack comprises: a plurality of support rods 1 each with a pulley installed at one end and a plurality of drying support units that can be sleeved on the plurality of support rods 1, wherein the support rods 1 are equipped with a first stopper 2 arranged close to the pulley, and each group of drying support units is detachably mounted with a drying frame 3, and a plurality of ventilation holes 4 are formed on the bottom of the drying frame 3;

[0029] The drying support unit includes a pair of first connecting arms 5 arranged in parallel and a pair of second connecting arms 6 arranged in parallel and capable of being hinged with the pair of first connecting arms 5 to form a parallelogram structure. Each first connecting arm 5 is provided with a plurality of sliding sleeves 7 which can be slidably mounted on the corresponding support rod 1. Each first connecting arm 5 is provided with a support adjustment mechanism, which can conflict with the support adjustment mechanism on the adjacent upper and / or lower first connecting arms 5. The drying frame 3 can be inserted into the inner side between the pair of first connecting arms 5 and the second connecting arm 6.

[0030] During assembly, first sleeve each sliding sleeve 7 on the drying support unit on the corresponding support rod 1. After several groups of drying support units are sleeved on the support rod 1, erect the support rod 1 so that the pulley on each support rod 1 contacts the ground. At this time, the drying support unit located at the bottom will conflict with the first limit member 2, and the support adjustment mechanism of the drying support unit will slide downward due to gravity and conflict with the support adjustment mechanism of the adjacent lower drying support unit. The number of drying support units sleeved on the support rod 1 can be adjusted according to the specific use environment and user needs.

[0031] Because a pair of first connecting arms 5 and a pair of second connecting arms 6 are hinged to form a parallelogram structure, the drying support unit can be folded when stored to reduce the storage space. After the drying support unit is mounted on the support rod 1, the support rod 1 is erected, and one group of drying support units is opened to unfold the folded parallelogram structure. The support rod 1 can be used to unfold other drying support units mounted on the support rod 1. The drying frame 3 is installed on one group of drying support units to fix it in the unfolded state of the corresponding drying support unit. The relative positions between several support rods 1 are also fixed, and then the drying racks are installed on other drying support units.

[0032] Because the support rod 1 will hinder the disassembly and installation of the drying frame 3, the sliding sleeve 7 is installed on a pair of first connecting arms 5. The drying frame 3 can be installed and disassembled through the space between the second connecting arm 6 and the second connecting arm 6 on an adjacent group of drying support units. It is also convenient for people to turn over the tea leaves drying in the drying frame 3.

[0033] During storage, several support rods 1 can be gathered together for storage, and the drying support unit can also be folded for storage, which can reduce the space required for storage.

[0034] The tops of the two side walls of the drying frame 3 corresponding to a pair of second connecting arms 6 are respectively provided with a first limiting flange 8 and a second limiting flange 9; the second connecting arm 6 opposite to the first limiting flange 8 is provided with a positioning sleeve 10 for sliding insertion of the first limiting flange 8; the second connecting arm 6 opposite to the second limiting flange 9 is provided with a limiting mechanism that can be detachably contacted with the top of the side wall of the drying frame 3; the height of the opening end of the positioning sleeve 10 is greater than the height of the first limiting flange 8.

[0035] After the parallelogram structure is unfolded, the first limiting flange 8 is first inserted into the positioning sleeve 10. Because the height of the opening end of the positioning sleeve 10 is greater than the height of the first limiting flange 8, the drying frame 3 can be rotated downward while the first limiting flange 8 is always inserted into the positioning sleeve 10, so that the drying frame 3 is inserted into the interior of the parallelogram structure. The second limiting flange 9 will be placed on the corresponding second connecting arm 6, so that the limiting mechanism and the side wall of the drying frame 3 are in contact with each other, and the drying frame 3 can be installed on the drying support unit; also because the drying frame 3 is installed on the drying support unit, it can prevent the one-to-one connecting arm and the pair of second connecting arms 6 from folding, so that it can always remain in the unfolded state.

[0036] The limiting mechanism includes a rotating arm 11 installed on the second connecting arm 6 away from the side wall of the drying frame 3 through a first hinged seat, a torsion spring 12 installed on the first hinged seat for pushing the rotating arm 11 to rotate close to the second connecting arm 6, and a limiting arm 13 fixedly arranged at the end of the rotating arm 11 away from the first hinged seat and whose lower surface can contact the top of the side wall of the drying frame 3.

[0037] When installing the drying frame 3, push the rotating arm 11 in the direction away from the second connecting arm 6, thereby driving the limiting arm 13 to move. After the second limiting flange 9 is placed on the corresponding second connecting arm 6, release the rotating arm 11, and the torsion spring 12 will rotate close to the second connecting arm 6 through the rotating arm 11, driving the limiting arm 13 to contact the upper surface of the side wall of the drying frame 3.

[0038] The support and adjustment mechanism includes a strip support plate 14 fixedly installed on the first connecting arm 5 away from the side wall of the drying frame 3 in the same length direction, a strip slide 15 fixedly installed on the first connecting arm 5 away from the side wall of the drying frame 3 in the same length direction and located below the strip support plate 14, a slider 16 adjustably slidably installed on the strip slide 15, a first support arm 17 whose upper end is hinged to the slider 16, and a second support arm 18 whose upper end is installed on the first connecting arm 5 via a second hinge seat, and the lower end of the second support arm 18 is hinged to the lower end of the first support arm 17.

[0039] The support and adjustment mechanism is used to separate the second connecting arms 6 in two adjacent groups of drying support units, which is beneficial for sunlight to irradiate the tea leaves and for air flow to remove moisture in time. The lower ends of the first support arm 17 and the second support arm 18 are in contact with the strip support plate 14 of the adjacent lower support and adjustment mechanism.

[0040] When it is necessary to adjust the distance between the two drying frames 3, the position of the slider 16 on the strip slide 15 is adjusted. When the slider 16 slides close to the second support arm 18, the distance between the lower ends of the first support arm 17 and the second support arm 18 and the strip slide 15 increases; when the slider 16 slides away from the second support arm 18, the distance between the lower ends of the first support arm 17 and the second support arm 18 and the strip slide 15 decreases.

[0041] The strip-shaped slide seat 15 is provided with a plurality of positioning holes 19 spaced apart along the length direction, and the slider 16 is threadedly connected with positioning bolts 20 whose ends can be inserted into the corresponding positioning holes 19 .

[0042] When it is necessary to adjust the position of the slider 16 on the bar slide 15, loosen the positioning bolt 20 so that the end portion moves from the corresponding positioning socket 19. At this time, the slider 16 can slide on the bar slide 15. Then loosen the positioning bolt 20 and insert the end portion of the positioning bolt 20 into the corresponding positioning socket 19, so that the slider 16 can be fixed on the bar slide 15.

[0043] A second limiting member 21 is detachably mounted on at least one of the support rods 1 , and a locking bolt 22 whose end can abut against the support rod 1 is threadedly connected to the second limiting member 21 .

[0044] After the support rod 1 is erected, the drying support unit located above will slide downward on the support rod 1, and the drying support units will be stacked in sequence under the action of gravity. When there is a bump in the transfer push, the sliding sleeve 7 mounted on the support rod 1 will slide slightly on the support rod 1, and the up and down collision will produce abnormal noise. Therefore, a second limit member 21 is provided. After several groups of drying support units are mounted on the support rod 1, the second limit member 21 is slidably mounted on the support rod 1 from the end away from the pulley. After the support rod 1 is erected, the second limit member 21 will contact the drying support unit located at the top, and the locking bolt 22 is tightened to fix the second limit member 21 on the corresponding support rod 1, so that the drying support unit cannot slide on the support rod 1 and can be fixed in the position of the drying support unit on the support rod 1.

[0045] The end of the rotating arm 11 away from the first hinge seat is provided with a pull ring, and the pull ring facilitates pulling the rotating arm 11 to slide away from the second connecting arm 6.

[0046] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0048] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
