[0036] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] like Figures 1 to 6As shown, a portable low-temperature refrigerator includes: a box body 1, a box lid 2, a locking assembly 3, and a folding and moving assembly 4. The box body 1 includes an outer box body 101 and an inner box body 102. The inner box body 102 is fixedly connected to the inside of the outer box body 101. A sealing ring 103 is fixedly connected to the top of the inner box body 102. The box lid 2 is located at the top of the box body 1. The box lid 2 includes an outer box lid 201 and an inner box lid 202. The outer box lid 201 is rotatably connected to the top of the outer box body 101. The inner box lid 202 is fixedly connected to the inside of the outer box lid 201. A handle 203 is rotatably connected to the top of the outer box lid 201. A clamping ring 204 is fixedly connected to the top of the outer box lid 201. The locking assembly 3 is located on the front side of the outer box lid 201 and the outer box body 101. The folding and moving assembly 4 is located at the bottom of the box body 1.

[0038] The sealing ring 103 is an elastic rubber ring. The bottom end of the inner box cover 202 is provided with a sealing groove. The sealing ring 103 fits tightly with the sealing groove to seal the gap between the inner box cover 202 and the inner box body 102. Both the inner box body 102 and the inner box cover 202 are made of heat insulation board. The clamping ring 204 is an elastic rubber clamping ring.

[0039] The locking assembly 3 includes a storage tube 301, a first plug 303, a fixing ring 304, and a first spring 305. The storage tube 301 is fixedly connected to the front side of the outer casing 101. A first limiting shaft 302 is fixedly connected to the inner side of the storage tube 301. The first plug 303 is slidably connected to the inner side of the storage tube 301 and is slidably connected to the first limiting shaft 302. The fixing ring 304 is fixedly connected to the outer side of the outer casing 201 and can be slidably inserted into the first plug 303. The first spring 305 is sleeved on the outer side of the first limiting shaft 302 and is fixedly connected between the bottom end of the inner side of the storage tube 301 and the bottom end of the first plug 303.

[0040] The folding and moving assembly 4 includes a support rod 401, a connecting rod 404, a first positioning ring 405, a second positioning ring 406, a positioning block 407, a second plug 409, and a second spring 411. The support rod 401 is rotatably connected to the bottom end of the outer housing 101. A caster wheel 402 is fixedly installed on the end of the support rod 401 away from the outer housing 101. A fixing rod 403 is fixedly connected between the support rods 401 rotating in the same direction. One end of the connecting rod 404 is rotatably connected to the outside of the fixing rod 403. The first positioning ring 405 is fixedly connected to the bottom end of the outer housing 101. The second positioning ring 406 is located on one side of the first positioning ring 405 and is fixed. The positioning block 407 is rotatably connected to the other end of the connecting rod 404 and is fixedly connected to the bottom end of the outer casing 101. The positioning block 407 has storage slots on both sides. The inner side of the storage slots is fixedly connected to the second limiting shaft 408. The second plug 409 is slidably connected to the inner side of the storage slots on both sides of the positioning block 407. The second plug 409 can be slidably inserted into the first positioning ring 405 and the second positioning ring 406. The bottom end of the second plug 409 is fixedly connected to the push knob 410. The second plug 409 is slidably connected to the second limiting shaft 408. The second spring 411 is sleeved on the outside of the second limiting shaft 408 and fixedly connected between the positioning block 407 and the second plug 409.

[0041] In practical use, simultaneously pressing the two push knobs 410 at the bottom of the positioning block 407 causes the second plug 409 to compress the second spring 411, pulling the second plug 409 out of the first positioning ring 405, thus unlocking the positioning block 407. Moving the positioning block 407 causes the connecting rod 404 to rotate, pushing the support rod 401 to rotate, causing the caster wheel 402 to unfold and contact the ground. Aligning the second plug 409 with the second positioning ring 406, releasing the push knobs 410 causes the second spring 411 to return to its original position, allowing the second plug 409 to slide into the second positioning ring 406, locking the positioning block 407, and locking the support rod 401 and connecting rod 404, thus completing the unfolding and locking of the folding and moving assembly 4. Removing the handle 203 from the clamp 204 and pulling the handle 203 allows the low-temperature refrigerator to be moved easily via the caster wheel 402.

[0042] When the container needs to be left to stand still, simply remove the positioning block 407 from the positioning ring 406 and move it to relock it inside the positioning ring 405. At this time, the support rod 401 will rotate and fold back into the inner side of the bottom of the outer box 101, so that the low-temperature refrigerator can be placed stably on the ground for use.

[0043] When you need to store or retrieve refrigerated items, simply pull down the latch 303 to remove it from the retaining ring 304, allowing the lid 2 to be rotated and opened for easy access. After storage or retrieval, rotate the lid 2 to close it, release the latch 303, and the spring 305 will return to its original position, allowing the latch 303 to slide into the inner side of the retaining ring 304, thus locking the lid 2.

[0044] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
