[0002] A refrigeration machine is a device that uses energy to transfer heat from a low-temperature area to a high-temperature area, thereby achieving a cooling effect. It is typically used for refrigerating items. A refrigeration machine mainly consists of a compressor, condenser, evaporator, and other structures. By dissipating the heat inside the refrigeration machine and generating cold air, heat is transferred from a low-temperature environment to a high-temperature environment, thus cooling the refrigeration compartment and achieving the purpose of refrigerating items.
[0003] When the refrigeration unit is in operation, staff need to move it into the designated cold storage space to expel heat and produce cold air. The refrigeration unit itself is heavy, and it is inconvenient to pull and control the direction of movement. The refrigeration unit is difficult to move and may collide with other units. Multiple people are needed to move the refrigeration unit. It is difficult for a single person to push the refrigeration unit. In addition, the refrigeration unit itself is relatively low, making it inconvenient for personnel to exert force when pushing it.
[0004] Therefore, a mobile refrigeration unit is proposed to address the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0029] Please see Figures 1-7 As shown, a mobile refrigeration unit includes a refrigeration unit body 1, a controller 11 installed on the front of the refrigeration unit body 1, an accessory slot 2 opened at the bottom of the refrigeration unit body 1, a moving component 21 installed at the bottom of the inner wall of the accessory slot 2, a sliding frame 3 fixedly installed on the right side of the refrigeration unit body 1, and a pulling component 31 slidably installed inside the sliding frame 3.
[0030] Furthermore, by installing a moving component 21 in the accessory slot 2 at the bottom of the refrigeration unit 1, the refrigeration unit 1 can be moved with the help of the moving component 21. A sliding frame 3 is installed on the right side of the refrigeration unit 1, so that the pulling component 31 can slide inside the sliding frame 3. The pulling component 31 can be adjusted to different heights, making it convenient for people of different heights to pull the pulling component 31 to move the refrigeration unit 1, thus achieving the effect of making it easier for different people to move the refrigeration unit 1.
[0031] First, considering the issue of how to move the pulling component 31 to facilitate pulling by people of different heights, the following is presented: Figure 1 , Figure 3 and Figure 4The specific structure of the pulling component 31 is disclosed. The pulling component 31 includes a sliding block 301 slidably installed inside the sliding frame 3. A mating interface is provided on the back of the sliding block 301. A connecting post 302 is rotatably installed inside the mating interface. A connecting rod 303 is fixedly installed on the back of the connecting post 302. A bayonet 304 is provided on the back of the connecting post 302. An installation port 305 is provided at the bottom of the inner wall of the bayonet 304. The bottom of the inner wall of the installation port 305 penetrates the connecting post 302 and extends into the interior of the connecting rod 303. A sliding groove 306 is provided on the right side of the connecting rod 303. An insertion joint is provided at the bottom of the inner wall of the installation port 305. The bottom of the inner wall of the insertion interface 307 extends into the interior of the slide groove 306. A locking post 308 is movably installed inside the bayonet 304. The back of the locking post 308 extends into the interior of the mounting port 305 and is fixedly installed with an upper limit ring 309. A return spring 310 is installed inside the mounting port 305. The front of the return spring 310 is fixedly installed on the back of the limit ring 309. The back of the return spring 310 is fixedly installed on the bottom of the inner wall of the mounting port 305. A plug-in post 311 is fixedly installed on the back of the limit ring 309. The back of the plug-in post 311 extends into the interior of the slide groove 306 and is fixedly installed with a pull block 312.
[0032] The sliding frame 3 has multiple locking interfaces 32 on its front side. The locking post 308 extends through the locking interface 304 and the sliding block 301 and into the interior of the locking interface 32, used to limit and fix the connecting rod 303 inside the sliding frame 3. A pull handle 4 is fixedly installed on the top of the connecting rod 303. There are two sliding blocks 301 and two return springs 310. The two sliding blocks 301 and the return springs 310 are symmetrically distributed inside the sliding frame 3.
[0033] Furthermore, by sliding the sliding block 301 inside the sliding frame 3, the connecting post 302 can be rotatably installed into the interface on the back of the sliding block 301. The connecting rod 303 is then fixedly installed on the back of the connecting post 302, allowing the connecting rod 303 to rotate within the sliding block 301. A bayonet 304 is formed on the left side of the connecting rod 303, and an installation opening 305 is formed at the bottom of the inner wall of the bayonet 304. The installation opening 305 penetrates the back of the connecting rod 303 and extends into its interior, allowing the return spring 310 to be installed inside the installation opening 305. The locking post 308 is movably installed inside the bayonet 304. The sliding frame 3 has multiple card slots 32 arranged in a linear array on its front side. The front side of the card post 308 is connected to the sliding block 301 through the front side of the sliding frame 305. One end of the return spring 310 is installed at the bottom of the inner wall of the mounting opening 305, and the other end of the return spring 310 is installed on the back side of the limit ring 309. A groove 306 is opened on the right side of the connecting rod 303, so that the pull block 312 can be slidably installed in the groove 306. A insertion interface 307 is opened at the bottom of the inner wall of 05, extending into the slide groove 306. The insertion post 311 is then inserted into the insertion interface 307. The front of the insertion post 311 is fixedly installed on the back of the limiting ring 309, and the back of the insertion post 311 is installed on the front of the pulling block 312. When a person pulls the pulling block 312 towards the center of the slide groove 306, the insertion post 311 and the locking post 308 move together. The locking post 308 then compresses the return spring 310 and moves towards the mounting opening 305. When the front of the locking post 308 has completely moved out of the locking interface 32, the sliding block 301 is no longer constrained, and the connecting rod 303 can then drive the sliding block 301. 1. Move the connecting rod 303 up and down within the sliding frame 3 to a suitable height. Then, release the pull block 312. The return spring 310, no longer under pressure, will push the locking pin 308 and the insertion pin 311 back to their original positions. This allows the locking pin 308 to re-insert into the locking interface 32 at the moving height position of the connecting rod 303, limiting the connecting rod 303 and the sliding block 301 within the sliding frame 3. At this time, the pull handle 4 at the top of the connecting rod 303 can be adjusted to a suitable height. Personnel can pull the pull handle 4 to move the refrigeration unit 1, achieving the effect of adjusting the pull handle 4 to different height positions, making it easier for personnel of different heights to pull the refrigeration unit 1. Simultaneously, the pull handle 4 can be used to tilt the pull block 312 to a more suitable angle for force output by utilizing the rotation angle of the connecting pin 302 within the sliding block 301.
[0034] It should be noted that both ends of the connecting rod 303 are equipped with sliding blocks 301, and two pulling blocks 312 are installed inside the slide groove 306. The two pulling blocks 312 can be squeezed at the same time to move towards the center of the slide groove 306, thereby retracting the locking pins 308 inside the two sliding blocks 301, thereby adjusting the height position of the connecting rod 303.
[0035] Secondly, considering the issue of how the refrigeration unit 1 can be limited and moved on the ground, a demonstration is provided. Figure 2 , Figure 5 , Figure 6 and Figure 7 The specific structure of the movable component 21 is disclosed. The movable component 21 includes a cabinet bottom plate 201 fixedly installed at the bottom of the inner wall of the accessory slot 2. A through opening 202 is provided at the top of the cabinet bottom plate 201. A limiting sleeve 203 is installed at the top of the cabinet bottom plate 201. An electric telescopic rod 204 is installed inside the limiting sleeve 203. A fixing plate 205 is fixedly installed at the bottom of the electric telescopic rod 204. The outer wall of the fixing plate 205 is fixedly installed on the inner wall of the limiting sleeve 203. Slide tracks 206 are provided on the left and right sides of the limiting sleeve 203. A caster wheel 207 is installed at the bottom of the cabinet bottom plate 201.
[0036] The casters 207 are located directly below the limiting sleeve 203, which is located inside the through opening 202. There are four casters 207 and four limiting sleeves 203, which are arranged in a rectangular array at the bottom of the refrigeration unit body 1.
[0037] Furthermore, an accessory slot 2 is formed at the bottom of the refrigeration unit body 1, and electric telescopic rods 204 are installed at the four corners of the accessory slot 2. A fixing plate 205 is installed at the bottom of the output shaft of the electric telescopic rod. The fixing plate 205 can be fixedly installed on the inner wall of the limiting sleeve 203 that is sleeved on the outer surface of the electric telescopic rod 204. Thus, when the electric telescopic rod 204 extends or retracts, it will drive the limiting sleeve 203 to extend or retract together. A cabinet bottom plate 201 is fixedly installed at the bottom of the inner wall of the accessory slot 2 to close the accessory slot 2. A caster wheel 207 is installed at the bottom of the cabinet bottom plate 201. The caster wheel 207 is installed directly below the limiting sleeve 203. A through opening 202 is formed at the bottom of the cabinet bottom plate 201. The left side of the limiting sleeve 203... Slide tracks 206 are provided on both right side walls, and the limiting sleeve 203 moves downward with the help of the electric telescopic rod 204. The limiting sleeve 203 covers and engages with the universal wheel 207, so that the bottom of the limiting sleeve 203 contacts the ground. When the refrigerator body 1 is moved, the pulling component 31 pulls the refrigerator body 1, so that the refrigerator body 1 moves to a position with the help of the four universal wheels 207 at the bottom. When the refrigerator body 1 moves to the designated position, the switch on the controller 11 can be pressed to power on the electric telescopic rod 204, so that the limiting sleeve 203 moves downward and covers the universal wheel 207 to abut against the ground, limiting the refrigerator body 1 and preventing the refrigerator body 1 from moving and colliding.
[0038] In summary, the working principle of this utility model is as follows:
[0039] When moving the refrigeration unit body 1, the operator squeezes the two pull blocks 312 and moves them towards the center of the slide groove 306. This moves the insertion post 311 and the locking post 308 together. The locking post 308 then compresses the return spring 310 and retracts. The locking post 308 is no longer inserted into the locking interface 32. Pulling the pull handle 4 upwards moves the connecting rod 303 and the sliding block 301 inside the sliding frame 3. After moving the pull handle 4 to the appropriate pulling height, the pull block 312 is released. The return spring 310 is no longer compressed and pushes the locking post 308 into the locking interface 32 at the current height. This limits and fixes the sliding block 301 inside the sliding frame 3, achieving the effect of adjusting the height of the pull handle 4. Furthermore, the pull handle 4 can rotate within the interface inside the sliding block 301 with the help of the connecting post 302, making it convenient for the operator to move the refrigeration unit by pulling the pull handle 4.
[0040] After the refrigeration unit 1 is moved to the designated position by means of the casters 207, the switch on the controller 11 is pressed to start the electric telescopic rod 204. The electric telescopic rod 204 drives the limiting sleeve 203 to move downward. The bottom of the limiting sleeve 203 passes through the through hole 202 and covers the outside of the casters 207, so that the limiting sleeve 203 can be pressed against the ground, thereby achieving the effect of limiting the refrigeration unit 1 and preventing the refrigeration unit 1 from deviating and colliding through the casters 207 at the bottom.
