[0002] Storage is to place food in a low-temperature environment for a long time. The low temperature environment inhibits the growth and reproduction of microorganisms, slows down the biochemical reactions in the food, inhibits the activity of enzymes, and uses low temperature to control the food from spoiling in a short period of time.

[0003] Among them, after searching, it was found that the application number is CN202123268996.9, a fresh meat storage device, which has a function of opening a round hole on the receiving plate to facilitate the water carried by the meat to drip onto the slide, and the contact area between the meat and the receiving plate can be reduced by the setting of the protrusion, further achieving the effect of facilitating the taking of the meat, and the setting of the placement block and the support block can facilitate the installation and removal of the slide; wherein, the shortcomings are as follows:

[0004] When the staff uses this fresh meat storage device to freeze and store meat food, they place the meat food on the receiving plate and then close the door to seal the meat food. At this time, moisture on the meat food will drip through the round hole onto the slideway, and the refrigerator will be started to cooperate with the air inlet hood and the return air duct to cool the inside of the device body. When the meat food is frozen and stored through the receiving plate, since only two receiving plates are set, when the staff places a large amount of meat food, the meat food will be stacked and squeezed, which will easily cause the meat food that cannot be well exposed to the low-temperature air inside to deteriorate quickly, making it a little inconvenient to freeze and store the piled meat food.

[0022] In the utility model:

[0023] Example 1: Reference Figure 1-6 A food transportation anti-extrusion storage rack comprises a freezer 1, a sealing cover 101, a support frame 102, a sliding bracket A2 and a storage rack 4. A sealing cover 101 is provided above the freezer 1 through a sealing ring for extrusion and sliding. A support frame 102 is fixedly installed below the inner wall of the freezer 1. Sliding brackets A2 are provided on both sides of the support frame 102, and the sliding brackets A2 are provided in a "U" shape. A storage rack 4 is provided below the sliding bracket A2. There are several storage racks 4, which are arranged in parallel at equal distances, and the surface of the storage rack 4 is arranged in a grid shape. A lifting and placing mechanism for conveniently placing and taking meat blocks by staff is provided on the outer side of the sliding bracket A2. Sliding disassembly and assembly mechanisms for conveniently disassembling and assembling the storage rack for maintenance by staff are provided on both sides of the sliding bracket A2, and a layered adjustment and placement mechanism for avoiding the accumulation of meat blocks is provided.

[0024] Reference Figure 2 , 3 5. Further, the lifting and placing mechanism is composed of a slide groove A103, a limit card groove 104, a handle 201, a slide groove B202, and a limit card frame 203;

[0025] Slide grooves A103 are relatively embedded on both sides of the inner wall of the freezer 1 and the support frame 102, and both sides of the sliding bracket A2 are slidably arranged between the inner sides of the relative slide grooves A103 through sliders. Limiting card grooves 104 are relatively embedded on both sides of the inner wall of the freezer 1 and the rear of both sides of the support frame 102, and the limiting card grooves 104 are arranged in an "L" shape. A handle 201 is fixedly installed on the top of the sliding bracket A2, and slide grooves B202 are relatively embedded on both sides of the sliding bracket A2. The slide grooves B202 and the relative A limit card frame 203 is slidably arranged between the inner sides of the limit card slot 104, and the limit card frame 203 is arranged in an "L" shape. When the staff needs to freeze and store a large amount of processed block beef, they open the sealing cover 101 and hold the handle 201 to pull one of the sliding brackets A2 to slide inside the slide groove A103 through the slider, so that the slide groove B202 and the limit card slot 104 are opposite to each other, and then the staff pushes the limit card frame 203 to slide into the limit card slot 104 from the side inside the slide groove B202, and then in the same way After the other limiting bracket 203 slides into the relative limiting slot 104, the sliding bracket A2 is released, and the sliding bracket A2 slides down a short distance in the slide slot A103 through the slider, so that the slide slot B202 and the limiting slot 104 are staggered, and the limiting bracket 203 is limited to complete the support of the sliding bracket A2, and the other sliding bracket A2 is pulled apart in the same way. After the staff puts a number of beef blocks on the surface of the storage rack 4, they hold the handle 201 and pull one of the sliding brackets A2 through After the slider slides upward a short distance on the inner side of the slide groove A103, so that the slide groove B202 and the limit card slot 104 are relatively loosened from the limit card bracket 203, the staff pushes the limit card bracket 203 to slide on the inner side of the slide groove B202. After sliding out of the limit card slot 104, the sliding bracket A2 is slowly lowered and slid downward on the inner side of the slide groove A103 by the slider to put it back to its original position, completing the placement of the beef block. The beef block can then be quickly taken out by the same pulling-out method, making it convenient for the staff to take and place the beef block.

[0026] Reference Figure 2-4 , further, the sliding disassembly mechanism is composed of a slide groove C204, a sliding bracket B3, a mounting groove 303, a damping telescopic rod B304, a limit block B305, a mounting block 401 and a limit groove B402;

[0027] Slide bracket A2 is relatively embedded with slide grooves C204 on both sides, and a slide bracket B3 is relatively slidably arranged on the inside of the slide groove C204 through a slider. There are several slide brackets B3, and each two are relatively equidistant and arranged in parallel. The side of the slide bracket B3 is embedded with a mounting groove 303, and the storage rack 4 is fixedly installed with mounting blocks 401 on both sides, and the mounting blocks 401 are slidably arranged on the inside of the mounting groove 303, and damping telescopic rods B304 are fixedly installed on both sides above the inner wall of the mounting groove 303 , and a spring is provided on the outside of the damping telescopic rod B304, a limit block B305 is fixedly installed below the end of the damping telescopic rod B304, and the limit block B305 is arranged in a semicircular shape, and limit grooves B402 are embedded on both sides above the mounting block 401, and the limit grooves B402 are arranged in a semicircular shape, and the limit block B305 is arranged in a sliding manner inside the limit grooves B402. When the staff unfolds the two sliding brackets A2 from the top of the freezer 1, it is necessary to place the beef block before placing the beef block. When the storage rack 4 is disassembled for cleaning, the storage rack 4 is pushed forward or backward to drive the mounting block 401 to slide inside the mounting groove 303, and the limit block B305 is squeezed to slide out of the limit groove B402 to drive the damping telescopic rod B304 and the outer spring to contract. After the mounting block 401 is released and the mounting block 401 slides out of the mounting groove 303, the disassembly of one of the storage racks 4 is completed, and the storage rack 4 that needs to be used is disassembled in the same way, and after cleaning, a large number of beef blocks that need to be frozen and stored are laid flat. Insert the storage rack 4, and slide the mounting blocks 401 on both sides of one of the storage racks 4 into the inner sides of the opposite mounting grooves 303, squeeze the limit block B305 to drive the damping telescopic rod B304 and the outer spring to contract, so that the limit groove B402 is close to the limit block B305, and the damping telescopic rod B304 and the outer spring pop out the limit block B305 to slide into the inner sides of the limit groove B402, limiting the storage rack 4, making it convenient for the staff to disassemble and maintain the storage rack 4, and at the same time, making it convenient for the staff to take and put the beef blocks.

[0028] Reference Figure 2-4 , further, the layered adjustment placement mechanism is composed of a limit groove A205, a damping telescopic rod A301 and a limit block A302;

[0029] A limiting groove A205 is embedded in the inner wall of the slide groove C204 near the front of the slide groove C204. There are several limiting grooves A205, which are equidistant and parallel, and the upper part of the inner wall of the limiting groove A205 is inclined. A damping telescopic rod A301 is fixedly installed on the side of the sliding bracket B3, and a spring is matched on the outer side of the damping telescopic rod A301. A limiting block A302 is fixedly installed on the end of the damping telescopic rod A301, and the upper part of the limiting block A302 is inclined, and the limiting block A302 is slidingly arranged on the inner side of the limiting groove A205. When the staff spreads a large amount of beef blocks on the surfaces of several storage racks 4, the staff installs one of the storage racks 4 back between the two uppermost installation grooves 303, and pushes the side limiting blocks A302 of the two sliding brackets B3 below to slide out of the limiting groove A205, and squeezes the damping telescopic rod A301 and the outer spring to contract, and releases. After the sliding bracket B3 is pushed by the staff to slide downward to a suitable height position on the inner side of the slide groove C204 through the slider, the limiting block A302 is released to make the blocking block A302 slide into the inner side of one of the relative limiting grooves A205. Then, the staff installs another storage rack 4 between the adjusted installation grooves 303, and adjusts the other pairs of sliding brackets B3 in the same way. After the storage racks 4 are installed, the sliding bracket A2 is released, and after driving the storage racks 4 to be placed in the freezer 1, the staff puts the sealing cover 101 back on the top of the freezer 1 to seal it. When a large number of beef blocks are frozen and stored for a long time, the large number of beef blocks placed in layers can be evenly contacted with the low-temperature air to achieve the freezing effect, which can avoid the beef blocks piling up and squeezing each other, resulting in the beef squeezed inside not being able to contact with the low-temperature air well and causing the meat to deteriorate easily.

[0030] Embodiment 2:

[0031] like Figure 6As shown, the utility model has a limit block B305 fixedly installed below the end of the damping telescopic rod B304, and the limit block B305 is arranged in a semicircular shape, and the limit grooves B402 are embedded on both sides above the mounting block 401, and the limit grooves B402 are arranged in a semicircular shape, and the limit block B305 is fitted and slidably arranged on the inner side of the limit groove B402. In addition to the embodiment, there is another embodiment in which the limit block B305 is fixedly installed below the end of the damping telescopic rod B304, and the limit block B305 is arranged in a relatively inclined shape on four sides, and the limit grooves B402 are embedded on both sides above the mounting block 401, and the limit grooves B402 are arranged in a relatively inclined shape on four sides, and the limit Block B305 is slidably arranged on the inner side of the limit groove B402. When the staff slides the mounting blocks 401 on both sides of one of the storage racks 4 into the inner side of the relative mounting groove 303, the limit block B305 is squeezed to drive the damping telescopic rod B304 and the outer spring to contract. After the limit groove B402 is close to the limit block B305, the damping telescopic rod B304 and the outer spring pop out the limit block B305 with four relatively inclined sides and slide into the inner side of the limit groove B402 with four relatively inclined sides, so that the limit block B305 and the limit groove B402 have a larger contact area and generate greater friction, so that the storage rack 4 is more stably limited. Compared with the first embodiment, the limiting effect is better.

[0032] Working principle: First, when the staff needs to freeze and store a large amount of processed beef blocks, they open the sealing cover 101 and hold the handle 201 to pull one of the sliding brackets A2 to slide inside the slide groove A103 through the slider, so that the slide groove B202 and the limiting card slot 104 are opposite to each other. Then, the staff pushes the limiting card bracket 203 to slide into the limiting card slot 104 from the side inside the slide groove B202, and then slides the other limiting card bracket 203 into the opposite limiting card slot 104 in the same way, releases the sliding bracket A2, and slides the sliding bracket A2 downward a short distance in the slide groove A103 through the slider, so that the slide groove B202 and the limiting card slot 104 are staggered, and then the limiting card bracket 203 is limited to complete the support of the sliding bracket A2, and then in the same way Pull open the other sliding bracket A2, then the staff pushes the storage rack 4 forward or backward to drive the mounting block 401 to slide inside the mounting groove 303, squeezes the limit block B305 to slide out of the limit groove B402, drives the damping telescopic rod B304 and the outer spring to contract, loosens the mounting block 401 and makes the mounting block 401 slide out of the mounting groove 303, completes the disassembly of one of the storage racks 4, and then disassembles the storage rack 4 to be used in the same way, and after cleaning, lays a large amount of block beef that needs to be frozen and stored flat into the storage rack 4, and slides the mounting blocks 401 on both sides of one of the storage racks 4 into the inner sides of the opposite mounting grooves 303, squeezes the limit block B305 to drive the damping telescopic rod B304 and the outer spring to contract, so that the limit groove B402 is close to the limit groove. After the limit block B305 is positioned, the damping telescopic rod B304 and the outer spring pop out the limit block B305 and slide into the inner side of the limit groove B402 to limit the storage rack 4. Finally, the staff pushes the side limit blocks A302 of the two sliding brackets B3 below to slide out of the limit groove A205, and squeezes the damping telescopic rod A301 and the outer spring to contract. The sliding bracket B3 is released and the staff pushes the sliding bracket B3 to slide downward on the inner side of the slide groove C204 to a suitable height position through the slider, then the limit block A302 is released, so that the block A302 slides into the inner side of one of the relative limit grooves A205, and the staff installs another storage rack 4 between the adjusted installation grooves 303, and adjusts the other pairs of sliding brackets B3 in the same way. After the storage rack 4 is installed, the handle 201 is held to pull one of the sliding brackets A2 to slide upward a short distance inside the slide groove A103 through the slider, so that the slide groove B202 and the limiting card slot 104 are relatively loosened from the limiting card bracket 203. Then, the staff pushes the limiting card bracket 203 to slide inside the slide groove B202. After sliding out of the limiting card slot 104, the sliding bracket A2 is slowly lowered and slid downward inside the slide groove A103 through the slider to return to its original position, completing the placement of the block beef. After the staff puts the sealing cover 101 back on the top of the freezer 1 to seal it, when a large number of block beef is frozen and stored for a long time, the large number of block beef placed in layers can be evenly exposed to the low-temperature air for freezing, which can avoid the block beef from piling up and squeezing each other.The beef squeezed inside cannot be in good contact with the low-temperature air, causing the meat to deteriorate easily.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
