Description

Technical Field

[0001] This utility model belongs to the technical field of food storage equipment, and in particular, it is a freezer rack for placing zongzi leaves. Background Technology

[0002] Fresh bamboo leaves have a high water content, making them prone to bacterial and mold growth at room temperature, leading to spoilage and rot. Freezing reduces microbial activity and inhibits their growth and reproduction, thus extending the shelf life of the bamboo leaves and maintaining their quality for a longer period. Traditional bamboo leaf freezing racks can meet basic usage needs, but their self-adaptive clamping force is weak, failing to effectively restrict the movement of the bamboo leaves. This results in uneven distribution of the leaves on the racks, affecting the efficient use of freezer space and hindering subsequent handling and retrieval.

[0003] A search revealed Chinese patent documents (authorization announcement number CN219995626U), which disclose a food freezing rack, relating to the field of food technology. This food freezing rack includes a storage box with a first storage plate fixedly connected inside. Two second storage plates are slidably connected inside the storage box. Two lead screws are fixedly connected inside the storage box, and each lead screw has a threaded connection to a movable block via a screw nut. The other ends of the four movable blocks are hinged to one side of two connecting rods, and the other ends of the four connecting rods are hinged to one side of the two second storage plates. A drive shaft is fixedly connected to the circumference of each lead screw, and a drive belt is driven to the circumference of the two drive shafts. A motor is fixedly connected to one side of the storage box, and the motor's output is fixedly connected to one side of one of the lead screws. This allows for easier storage and retrieval of items. While this freezing rack meets basic usage needs, its self-adaptive clamping force is weak, failing to effectively restrict the movement of bamboo leaves, resulting in uneven distribution of the leaves on the rack. This affects the efficient use of the freezer space and hinders subsequent organization and retrieval. Utility Model Content

[0004] The purpose of this invention is to provide a freezer rack for zongzi leaves to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a zongzi leaf freezing rack, comprising a freezer box for heat preservation, wherein multiple support frames are slidably arranged inside the freezer box, and a fixing block is welded to the top of each of the multiple support frames;

[0006] The fixed block has a rotating groove inside for rotation, and a rotating shaft is rotatably connected inside the rotating groove. A spring for limiting the position is connected to the outer periphery of the rotating shaft. An L-shaped plate is installed on the outer periphery of the rotating shaft. A movable frame is movably connected to the end of the L-shaped plate. A semi-circular pressure plate for pressing the zongzi leaves is installed at the end of the movable frame away from the L-shaped plate.

[0007] Preferably, the inner bottom wall of the freezer is welded with a rotating seat for limiting position, and the rotating seat is rotatably connected to a rotating column for rotation, and a rotating disk is welded to the end of the rotating column.

[0008] Preferably, a connecting column is welded to the side of the rotating disk away from the rotating column, a support plate is installed on the outer periphery of the connecting column, and multiple sliding grooves are provided on the outer periphery of the connecting column.

[0009] Preferably, four buffer springs are symmetrically installed on the top of the support plate, and one end of each of the four buffer springs is connected to the bottom of the support frame.

[0010] Preferably, the end of the support frame is slidably disposed inside the groove, and the top of the support frame is equipped with a placement plate for placing frozen bamboo leaves.

[0011] Preferably, the surface of the placement plate is provided with a guide hole for water flow, and a threaded rod is installed on the outer periphery of the connecting column, with a limit nut rotatably connected to the outer periphery of the threaded rod.

[0012] Preferably, the freezer box has a door installed on its side and a freezer compartment for refrigeration installed on its top.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This zongzi leaf freezing rack, thanks to its semi-circular pressure plate structure, allows for easy operation. Pulling the L-shaped plate causes it to rotate the shaft within a groove, which in turn moves the movable frame and semi-circular pressure plate upwards. This causes the spring to deform, separating the semi-circular pressure plate from the placement plate. Opening the door allows the zongzi leaves to be frozen to be placed between the semi-circular pressure plate and the placement plate. Releasing the L-shaped plate resets the spring, which then rotates the L-shaped plate and movable frame. The movable frame moves the semi-circular pressure plate closer to the zongzi leaves, ultimately securing them in place. Compared to traditional zongzi leaf freezing racks with weaker adaptive clamping force, this structure enhances this force, effectively limiting leaf movement, increasing the efficient use of freezer space, and facilitating subsequent handling and retrieval.

[0015] This bamboo leaf freezing rack, thanks to its structure of cushioning springs and support frames, allows bamboo leaves with high moisture content to be placed inside. Some of the water flows down the placement plate through the drainage holes until it flows into the bottom of the freezer. The cushioning springs prevent vibrations generated when the freezer moves from affecting the frozen bamboo leaves, thus protecting them from damage. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The illustrated zongzi leaf freezing rack includes a freezer box 1 for heat preservation. Multiple support frames 203 are slidably arranged inside the freezer box 1, and a fixing block 3 is welded to the top of each of the multiple support frames 203.

[0027] The fixed block 3 has a rotating groove 301 inside for rotation. A rotating shaft 303 is rotatably connected inside the rotating groove 301. A spring-loaded spring 302 for limiting the rotation is connected to the outer periphery of the rotating shaft 303. An L-shaped plate 304 is installed on the outer periphery of the rotating shaft 303. A movable frame 305 is movably connected to the end of the L-shaped plate 304. A semi-circular pressing plate 306 for pressing the bamboo leaves is installed at the end of the movable frame 305 away from the L-shaped plate 304. The semi-circular pressing plate 306 is made of a corrosion-resistant, low-temperature-resistant, and lightweight material, such as food-grade polypropylene (PP) or aluminum alloy. PP material has a low cost and good toughness, which can prevent brittleness in low-temperature environments and will not cause hard damage to the bamboo leaves. Aluminum alloy has high strength and good durability. It is not easy to rust even in a humid freezing environment for a long time, and effectively prevents rust during the freezing process. To prevent the bamboo leaves from shifting, sliding, or becoming disorderly due to factors such as cold air flow and vibration of the placement rack, the bamboo leaves are kept in a neat arrangement for easy management and retrieval. Pulling the L-shaped plate 304 causes the rotating shaft 303 to rotate within the rotating groove 301. The L-shaped plate 304 then moves the movable frame 305 and the semi-circular pressure plate 306 upwards, causing the spring 302 to deform. The semi-circular pressure plate 306 separates from the placement plate 204. Opening the door 101, the bamboo leaves to be frozen are placed between the semi-circular pressure plate 306 and the placement plate 204. Releasing the L-shaped plate 304 resets the spring 302, which in turn rotates the L-shaped plate 304 and the movable frame 305. The movable frame 305 then moves the semi-circular pressure plate 306 closer to the bamboo leaves, ultimately securing the bamboo leaves with the semi-circular pressure plate 306 and the placement plate 204.

[0028] The inner bottom wall of the freezer 1 is welded with a rotating seat 103 for limiting the position. The rotating seat 103 is rotatably connected to a rotating column 104 for rotation. A rotating disk 105 is welded to the end of the rotating column 104. A connecting column 106 is welded to the side of the rotating disk 105 away from the rotating column 104. A support disk 2 is installed on the outer periphery of the connecting column 106. Multiple sliding grooves 201 are provided on the outer periphery of the connecting column 106. When the rotating disk 105 is rotated, the rotating disk 105 drives the rotating column 104 to rotate inside the rotating seat 103. The support disk 2 and the placement plate 204 rotate. By repeating the above steps, multiple sets of zongzi leaves that need to be frozen can be fixedly placed.

[0029] Four buffer springs 202 are symmetrically installed on the top of the support plate 2. One end of each buffer spring 202 is connected to the bottom of the support frame 203. The end of the support frame 203 is slidably disposed inside the slide groove 201. A placement plate 204 for placing frozen bamboo leaves is installed on the top of the support frame 203. A guide hole 205 for water flow is provided on the surface of the placement plate 204. A threaded rod 4 is installed on the outer periphery of the connecting column 106. A limit nut 401 is rotatably connected to the outer periphery of the threaded rod 4. If the bamboo leaves placed in have a large amount of water, some water will flow down along the placement plate 204 through the guide hole 205 until it flows into the bottom of the freezer 1. The buffer springs 202 can prevent the vibration generated when the freezer 1 moves from affecting the frozen bamboo leaves, thereby protecting the bamboo leaves from damage.

[0030] A door 101 is installed on the side of the freezer 1. The door 101 prevents cold air from escaping and improves freezing efficiency. A freezer compartment 102 for refrigeration is installed on the top of the freezer 1. The freezer compartment 102 is the core part of the refrigeration unit and mainly includes components such as a compressor, condenser, evaporator, and expansion valve. The compressor compresses the refrigerant into a high-temperature, high-pressure gas. After being cooled by the condenser, it becomes a high-pressure liquid. Then, it passes through the expansion valve to reduce its pressure and enters the evaporator, where it absorbs heat and evaporates, thereby achieving the refrigeration effect.

[0031] Working principle

[0032] When using this zongzi leaf freezing rack, first pull the L-shaped plate 304. The L-shaped plate 304 drives the rotating shaft 303 to rotate within the rotating groove 301. The L-shaped plate 304 drives the movable frame 305 and the semi-circular pressure plate 306 to move upwards. The spring-loaded spring 302 deforms, and the semi-circular pressure plate 306 separates from the placement plate 204. Open the door 101 and place the zongzi leaves to be frozen between the semi-circular pressure plate 306 and the placement plate 204. Release the L-shaped plate 304, and the spring-loaded spring 302 returns to its original position. The spring-loaded spring 302 drives the L-shaped plate 304 and the movable frame 305 to rotate. The movable frame 305 drives the semi-circular pressure plate 306 to move upwards. Plate 306 moves closer to the bamboo leaves, and finally the semi-circular pressing plate 306 and the placement plate 204 fix the bamboo leaves. Rotate the rotating disk 105, and the rotating disk 105 drives the rotating column 104 to rotate in the rotating seat 103. The support plate 2 and the placement plate 204 rotate. Repeat the above steps to fix and place multiple sets of bamboo leaves that need to be frozen. If the bamboo leaves have a high moisture content, some of the water will flow down along the placement plate 204 through the guide hole 205 until it flows into the bottom of the freezer box 1. The buffer spring 202 can prevent the vibration generated when the freezer box 1 moves from affecting the frozen bamboo leaves, thereby protecting the bamboo leaves from damage.
