Description

Technical Field

[0001] This utility model relates to the technical field of cooling rack equipment, specifically a foldable and retractable cooling rack. Background Technology

[0002] Nowadays, tea processing requires the use of cooling racks. These racks are key equipment used to spread fresh leaves evenly after withering or fixing, promoting moisture loss and material transformation. In the early days, bamboo or wooden frames with multi-layered mesh designs were used, relying on natural ventilation and manual turning. They were suitable for small-scale production. Through breathable materials, they ensure air circulation, prevent fresh leaves from piling up and generating heat, and assist in withering or pre-cooling.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most traditional cooling racks are now fixed structures, bulky, require a lot of space to store, are inconvenient to transport, and are not suitable for small workshops or use in multiple scenarios. Their simple structure makes them easy to tip over or shake, which can pose safety hazards. In addition, the cooling nets are not easy to disassemble, and the gaps can easily trap dirt and grime, making them difficult to clean and potentially posing food safety risks. Furthermore, bamboo and wood materials need to be replaced frequently, and the cost of manual maintenance is high. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 The present invention provides a technical solution: including a folding component 2, a universal wheel 1 at the bottom of the folding component 2, a telescopic component 3 at the top of the folding component 2, a connecting pipe 4 fixedly installed at the top of the telescopic component 3, a sliding rod 6 movably connected at the perforation on the surface of the connecting pipe 4, a cooling net 5 movably connected to the connecting pipe 4 through the sliding rod 6, and a pull rod 7 movably connected inside the perforation on the surface of the sliding rod 6.

[0024] The folding assembly 2 includes a support column 201 and a folding column 202. The inner wall of the folding column 202 is rotatably connected to one end of a folding rod 203 via a rotating rod. Both sides of the folding column 202 are rotatably connected to one end of a connecting rod 204 via round rods. The inner wall of the folding rod 203 is rotatably connected to a movable block 205 via a short rod. The other end of the folding rod 203 is fixedly installed with a rotating shaft 206. The inner wall of the support column 201 is slidably connected to a locking block 208. A base 207 is fixedly installed on the surface of the locking block 208.

[0025] In this embodiment, as Figure 2 As shown, sliding holes are provided on both sides of the folding rod 203, a baffle is provided on the inner wall of the folding rod 203, and a rectangular block is provided at the bottom of the inner wall of the folding rod 203. A spring is fixedly installed on the surface of the rectangular block.

[0026] In this embodiment, as Figure 3 As shown, a dovetail groove is provided on one side of the support column 201, and the locking block 208 is slidably connected in the dovetail groove. A rectangular groove is provided on one side of the folding column 202. The other end of the connecting rod 204 is slidably connected in the sliding hole through the fixing rod. The rotating shaft 206 is rotatably connected to the inner wall of the base 207 through the base rotating rod.

[0027] In this embodiment, as Figure 4 As shown, the telescopic assembly 3 includes an inner tube 301 and an outer tube 302. The surface of the inner tube 301 is provided with a groove. The inner tube 301 is sleeved on the inner wall of the outer tube 302. The surface of the outer tube 302 is provided with a mounting shell 303.

[0028] In this embodiment, as Figure 5 As shown, the inner wall of the mounting shell 303 is rotatably connected to the eccentric wheel rod 304 via the outer shell rotating rod, and the inner wall of the groove is slidably connected to the protrusion 305. The surface of the protrusion 305 is fixedly installed with the return spring rod 306, and one end of the return spring rod 306 is fixedly installed at the bottom of the mounting shell 303.

[0029] In this embodiment, as Figure 2 As shown, two circular grooves are opened at both ends of the cooling net 5, and the sliding rod 6 is movably connected in the circular grooves.

[0030] In this embodiment, as Figure 2 As shown, a round hole is provided on one side of the connecting pipe 4, and the pull rod 7 is movably connected to the sliding rod 6 through the round hole.

[0031] like Figures 1 to 5 As shown, this foldable cooling rack operates as follows during use:

[0032] When the cooling rack needs to be stored, first pull one side of the lever 7, so that one end of the lever 7 moves out of the through hole of the sliding rod 6, thereby moving it out of the interior of the connecting tube 4. Then pull one side of the sliding rod 6, so that the sliding rod 6 moves out of the round hole of the cooling net 5, thereby moving it out of the interior of the connecting tube 4. At this time, pull the other side of the lever 7 out of the connecting tube 4, so that one end of the cooling net 5 is connected between the connecting tubes 4 through the sliding rod 6. Because the other end loses support, the cooling net 5 is tilted. At this time, turn the eccentric wheel rod 304 to one side. When the eccentric wheel rod 304 is no longer in contact with the protrusion 305, the reset spring rod 306 drives the protrusion 305 to rebound, so that the protrusion 305 is no longer in contact with the groove on the surface of the inner tube 301. At this time, the inner tube 301 can retract into the inner wall of the outer tube 302, so that the height of the cooling rack is shortened.

[0033] Pushing the folding rod 203 downwards causes one end of the connecting rod 204 to rotate on the surface of the folding column 202 via a round rod. This causes the other end of the connecting rod 204 to slide to the left through the sliding hole via a fixed rod. When it slides to the upper end of the baffle, the fixed rod contacts the movable block 205, causing its bottom spring to be compressed. The movable block 205 then becomes horizontal, allowing the fixed rod to pass through. Simultaneously, the other end of the connecting rod 204 rotates within the base 207 via the rotating shaft 206, causing the locking block 208 to slide downwards within the dovetail groove. This causes the support column 201 to move closer to the folding column 202, thus shortening the width of the cooling rack for easier storage.
