Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea fermentation rack structure. Background Technology

[0002] Tea fermentation is an important process in tea making, mainly used to enhance the aroma, taste, and color of tea. Different types of tea develop various flavors and characteristics through different degrees of fermentation. Key factors in the fermentation process include temperature, humidity, time, and the type and state of the tea itself. Different tea varieties and processes will determine the final degree of fermentation and the flavor of the tea.

[0003] During the long-term fermentation of tea, a rack-like structure is needed to hold the tea containers and aid in the fermentation process. Currently, traditional racks are fixed and cannot maximize vertical space utilization, resulting in a large floor area requirement. This is especially problematic when processing multiple batches of tea, as they are difficult to disassemble, clean, and maintain, and require significant space during transport, increasing operational costs. Furthermore, instability or movement during fermentation can cause unevenness in the tea trays, affecting the fermentation effect. Therefore, this invention proposes a tea fermentation rack structure to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tea fermentation rack structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tea fermentation rack structure includes a base, an assembly shaft fixed at the center of the upper side of the base, a plurality of limiting grooves evenly formed on one side of the assembly shaft, an mounting sleeve rotatably connected to the assembly shaft at the upper end of the limiting groove, a structural frame at the outer end of the mounting sleeve, a tray at the center of the upper side of the structural frame, a sliding shaft passing through the center of the structural frame fixed at the lower side of the tray, a placement plate at the upper side of the tray, a plurality of sliders slidably connected to the structural frame, a connecting rod between the lower end of each slider and the tray, an extrusion block corresponding to the outer side of the placement plate at the inner side of the slider, and a support plate between the lower side of the structural frame and the assembly shaft.

[0006] Preferably, a buckle block is fixed to the inner end of the structural frame, and a buckle groove corresponding to the buckle block is opened inside the mounting sleeve.

[0007] Preferably, the shape of the buckle corresponds to the inside of the limiting groove, and the lower end of the limiting groove has an assembly opening for the corresponding buckle.

[0008] Preferably, the tray slides up and down on the structural frame via the lower sliding shaft II, and a spring II is provided between the tray and the lower structural frame, sleeved around the sliding shaft II, and a limit block is fixed at the lower end of the sliding shaft II.

[0009] Preferably, a sliding shaft is fixed to the outside of the extrusion block and passes through the slider. A spring is provided between the extrusion block and the slider and is sleeved on one side of the sliding shaft. Both ends of the connecting rod are rotatably connected to the tray and the slider.

[0010] Preferably, the upper end of the support plate is rotatably connected to the structural frame, the assembly shaft is fixed with a plurality of locking studs located on the opposite side of the limiting groove, the lower end of the support plate has an opening corresponding to the locking studs, and the locking studs are threaded with locking nuts that are close to the outside of the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model is compact and reasonable. By stacking multiple placement trays, the vertical space can be maximized to meet the fermentation needs of different batches of tea. Each placement tray can be stably connected by a slider and a linkage mechanism to avoid occupying too much space. 2. This utility model is designed to facilitate quick disassembly, transportation and maintenance. The placement tray can be easily removed through a simple sliding shaft structure, and the structural frame can be quickly disassembled by unlocking and rotating, which is convenient for cleaning, maintenance or replacement of parts, and is more convenient in transportation and daily use. 3. The combination of the support plate and the assembly shaft in this utility model ensures that the structural frame is stable and does not shake during the fermentation process. The spring design provides additional support and elasticity, preventing the tea tray from becoming uneven. The pressing block fixing structure can adapt to the fixing needs of trays within a certain size range, ensuring the stability of tea fermentation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A tea fermentation rack structure includes a base 1, an assembly shaft 2 fixed at the center of the upper side of the base 1, a plurality of limiting grooves 5 evenly opened on one side of the assembly shaft 2, an installation sleeve 4 rotatably connected to the assembly shaft 2 at the upper end of the limiting groove 5, a structural frame 9 at the outer end of the installation sleeve 4, a tray 11 at the center of the upper side of the structural frame 9, a sliding shaft 2 17 passing through the center of the structural frame 9 fixed at the lower side of the tray 11, and a placement tray 3 at the upper side of the tray 11. The tea to be fermented is placed in the placement tray 3, and the placement tray 3 is placed in the structural frame 9. The structural frame 9 is assembled on the assembly shaft 2 through the installation sleeve 4, and a plurality of placement trays 3 are stacked on top of each other. Several sliders 12 are arranged around the periphery of the placement tray 3. The sliders 12 are slidably connected to the structural frame 9. A connecting rod 19 is provided between the lower end of each slider 12 and the tray 11. A pressing block 13 corresponding to the outer side of the placement tray 3 is provided on the inner side of the slider 12. A support plate 10 is provided between the lower side of the structural frame 9 and the assembly shaft 2. The tray 11 slides up and down on the structural frame 9 via a lower sliding shaft 17. A spring 18 is provided between the tray 11 and the lower structural frame 9 and is sleeved around the sliding shaft 17. A limit block is fixed at the lower end of the sliding shaft 17. Both ends of the connecting rod 19 are rotatably connected to the tray 11 and the sliders 12. A sliding shaft 14 penetrating the slider 12 is fixed on the outer side of the pressing block 13. A spring 15 is provided between the pressing block 13 and the slider 12 and is sleeved around the sliding shaft 14. After the tea-filled tray 3 is placed on the tray 11, the tray 11 slides down under the weight of the tray 3. The spring 18 on the side of the sliding shaft 17 is compressed. The slide of the tray 11 pulls several connecting rods 19. The connecting rods 19 drive the connected slider 12 to move closer to the center of the frame 9. The inner pressing block 13 of the slider 12 contacts the edge of the central tray 3, which serves to fix the central tray 3. The sliding shaft 14 structure connecting the pressing block 13 provides a redundancy in the fixing range of the tray 3. The pressing block 13 moves to the side of the outer slider 12. The spring 15 on the side of the central sliding shaft 14 is compressed. At the same time, the spring 15 is pressed towards the center by the outer pressing block 13, so that the weight of the tray 3 is used to fix the tray 3. A buckle 16 is fixed inside the structural frame 9. The mounting sleeve 4 has a buckle groove corresponding to the buckle 16 inside. The shape of the buckle 16 corresponds to the inside of the limiting groove 5. The lower end of the limiting groove 5 has an assembly opening 6 corresponding to the buckle 16. The upper end of the support plate 10 is rotatably connected to the structural frame 9. The assembly shaft 2 is fixed with several locking studs 7 located on the opposite side of the limiting groove 5. The lower end of the support plate 10 has an opening corresponding to the locking studs 7. The locking studs 7 are threaded with locking nuts 8 that are close to the outside of the support plate 10. The structure of the support plate 10 not only strengthens the connection between the structural frame 9 and the assembly shaft 2, but also provides stable support for the structural frame 9 on the assembly shaft 2, ensuring that the upper structural frame 9 can be stably assembled on the assembly shaft 2. When it is necessary to remove the placement tray 3, simply push the sliding shaft 17 upwards. Several sliders 12 around the placement tray 3 will move outwards, making it easy to remove the placement tray 3 from the structural frame 9. When it is necessary to disassemble, replace, or maintain the structural frame 9, first release the lower end of the connected support plate 10 from its fixation, rotate the locking nut 8, and the support plate 10 can be rotated downwards and detached from the surface of the assembly shaft 2. Then, rotate the assembled mounting sleeve 4 structure by 180 degrees. At this time, the buckle 16 at the inner end of the structural frame 9 corresponds to the limiting groove 5 on one side. The buckle 16 can then slide down along the corresponding limiting groove 5 until the buckle 16 corresponds to the lower end of the limiting groove 5 assembly opening 6, and the structural frame 9 can be removed from the mounting sleeve 4. At this time, it is very convenient to inspect and maintain the placement structure or to disassemble and transport the entire placement frame structure, greatly improving the application scenarios of the placement frame structure.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
