Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a convenient storage and retrieval freezer preservation device, including a cabinet 1 and a storage section 2.
[0032] The cabinet 1 is equipped with a refrigeration unit. The refrigeration principle of the cabinet 1 is that the electric motor provides mechanical energy, which is used by the compressor to perform work on the refrigeration system. The refrigeration system uses a low-boiling-point refrigerant, which absorbs heat when it evaporates. The above is the prior art, and will not be described in detail below. The cabinet 1 has a flip cover 101 that is rotatably mounted on the top of the cabinet 1. A sealing strip is provided at the point where the flip cover 101 abuts against the cabinet 1. The cabinet 1 has a storage cavity 102 inside, and the storage part 2 is located inside the cabinet 1. A base frame 201 is slidably mounted at the bottom of the storage cavity 102. A bidirectional lead screw 203 is rotatably mounted longitudinally inside the base frame 201. Two transmission frames 205 are slidably mounted longitudinally inside the base frame 201. The bidirectional lead screw 203 passes through the two transmission frames 205 and is threadedly connected to them. A transmission rod 206 is rotatably mounted on the top of each of the two transmission frames 205. The middle of the two transmission rods 206 is inserted into a rotating shaft and rotatably connected to each other in an X-shape. The structure features a lifting frame 207 rotatably mounted on the top of the transmission rod 206, and a storage rack 209 vertically sliding inside the storage cavity 102. The bottom of the storage rack 209 abuts against the lifting frame 207. The rotation of the bidirectional lead screw 203 drives the two transmission frames 205 to move, thereby causing the lifting frame 207 on the top of the transmission rod 206 to move up and down, and thus causing the storage rack 209 to move up and down. The rotation of the bidirectional lead screw 203 can drive the two transmission frames 205 to move inside the base frame 201, thereby causing the two displaced transmission frames 205 to drive the transmission rod 206 to rotate, which in turn causes the lifting frame 207 rotatably mounted on the top of the transmission rod 206 to push the storage rack 209 up, making it convenient for users to store and retrieve items.
[0033] Example 2
[0034] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment provides a technical solution: a convenient storage and retrieval freezing and preservation device, including a storage section 2, a transmission frame 205, and a storage rack 209.
[0035] A sliding groove a103 is provided on the inner wall side of the storage cavity 102. A slider 210 is provided on the side of the storage rack 209.

A rotating groove is provided horizontally inside the cabinet 1, and the drive shaft 104 is embedded in the rotating groove. Rotatably connected to cabinet 1, a motor 106 is installed on the side of cabinet 1. The output end of motor 106 is connected to drive shaft 104, which can drive drive shaft 104 to rotate inside cabinet 1. A sliding groove b202 is provided inside the base frame 201. There are two sliding grooves b202. Two transmission frames 205 are each embedded in one sliding groove b202 and are longitudinally slidably connected to the base frame 201, allowing the two transmission frames 205 to slide along the sliding groove b202 on the base frame 201. The internal displacement is achieved by a rotating groove inside the base frame 201. A bidirectional lead screw 203 is embedded in the rotating groove and rotatably connected to the base frame 201. The bidirectional lead screw 203 has threads with opposite ends. The two transmission frames 205 have identical threaded grooves inside. The bidirectional lead screw 203 passes through the two transmission frames 205 and is threadedly connected to them. The rotation of the bidirectional lead screw 203 can drive the two transmission frames 205 threadedly connected to it to move in opposite directions simultaneously. A bevel tooth b204 is provided at one end of the bidirectional lead screw 203. Four bevel teeth a105 are arranged at equal intervals along the direction of the transmission shaft 104. The bevel teeth a105 mesh with the bevel teeth b204. The rotation of the bevel teeth a105 can drive the bevel teeth b204 to rotate. A roller 208 is provided at the top of the lifting frame 207. The roller 208 abuts against the bottom of the storage rack 209, allowing the roller 208 to slide against the bottom of the storage rack 209.
[0036] Working principle: First, the device is powered on. Then, the motor 106 drives the transmission shaft 104 to rotate inside the cabinet 1, so that the bevel gear a105 on the transmission shaft 104 can drive the bevel gear b204 to rotate, which in turn drives the bidirectional lead screw 203 to rotate inside the base frame 201. Through the rotation of the bidirectional lead screw 203, the two transmission frames 205 threaded to the bidirectional lead screw 203 are simultaneously displaced in opposite directions, so that the two displaced transmission frames 205 drive the transmission rod 206 to rotate, which in turn causes the lifting frame 207 at the top of the transmission rod 206 to push the storage rack 209 to rise, making it convenient for users to store and retrieve items.
