Description

Technical Field

[0001] This utility model relates to the field of cold-color changing cup sleeve technology, and in particular to a portable adaptive cold-color changing cup sleeve. Background Technology

[0002] In modern society, people need to use cups to hold liquids in their daily lives, which is relatively hygienic. However, the problem is that when using a cup to drink hot or cold water, the cup has poor heat and cold insulation, and users are prone to burning or freezing their hands when holding the cup. Therefore, cup sleeves are needed to insulate against heat and cold.

[0003] Common portable adaptive color-changing cup sleeves only include heat insulation and cold insulation functions, which can isolate the heat and cold of the cup body, but lack adjustment function. They cannot guarantee that the size of the cup sleeve around the cup body can fit cups of different sizes. It is easy for the cup sleeve size to be fixed. When the cup sleeve is put on cups of different sizes, the cup sleeve cannot fit on the larger cups, and the cup sleeve cannot be firmly connected to the cups of smaller sizes, affecting the fit of the cup sleeve.

[0004] Therefore, while the aforementioned portable adaptive cold-changing color-changing cup sleeve has heat insulation and cold preservation functions and can block temperature differences in the cup, its lack of an adaptive adjustment structure results in a fixed cup sleeve size, which easily leads to compatibility issues when adapting to cups of different sizes. There is an urgent need to design a new type of portable adaptive cold-changing color-changing cup sleeve. Utility Model Content

[0005] To overcome the common problem of portable adaptive cold-changing cup sleeves having heat insulation and cold-keeping functions, which can block temperature changes in the cup, but due to the lack of an adaptive adjustment structure, the cup sleeve size is fixed and compatibility issues are prone to occur when adapting to different cup sizes.

[0006] The technical solution of this utility model is as follows: a portable adaptive cold-changing color cup sleeve, including a rear washable nylon sleeve; it also includes a front washable nylon sleeve, a shrink box, a shrink groove, a rotating groove, a take-up shaft, an upper disc, a rotating block, a lower disc, and a rotating knob. The front washable nylon sleeve is provided on the front side of the rear washable nylon sleeve, and the shrink box is provided on the right side of the rear washable nylon sleeve and the front washable nylon sleeve. A shrink groove is provided in the middle of the left side of the shrink box, and a rotating groove is provided in the center of the top of the shrink box. A take-up shaft is provided in the center of the inside of the shrink box, and an upper disc is provided at the top of the take-up shaft. A rotating block is provided in the center of the top of the upper disc, and a lower disc is provided at the bottom of the take-up shaft. A rotating knob is provided in the center of the bottom of the shrink box.

[0007] Preferably, rotating the lower disc via a rotary knob causes the winding shaft to rotate, which in turn drives the upper disc to rotate. The upper disc then causes the rotating block to rotate within the rotating groove. Simultaneously, the winding shaft winds up or unwinds the right ends of the rear and front washable nylon sleeves, thereby adjusting the size of the sleeves after they are spread out. This achieves an adaptive adjustment function, addressing the common problem of portable adaptive cold-changing cup sleeves that only provide heat and cold insulation, thus lacking an adjustment function. This makes it difficult to ensure that the size of the sleeve around the cup fits cups of different sizes. Consequently, the sleeve may become fixed in size, failing to fit larger cups and failing to securely attach to smaller cups, thus affecting the sleeve's adaptability.

[0008] Preferably, the right ends of both the rear wash nylon sleeve and the front wash nylon sleeve pass through the shrink groove and are connected to the take-up shaft.

[0009] Preferably, the top of the rotating block is inserted into the interior of the rotating groove, and the top of the rotating knob passes through the shrink box and connects to the bottom center of the lower disc.

[0010] Preferably, a left connecting sleeve is provided on the left side of the rear washable nylon sleeve and the front washable nylon sleeve, and the left ends of the rear washable nylon sleeve and the front washable nylon sleeve are sewn together with the left connecting sleeve.

[0011] Preferably, a right connecting sleeve is provided in the middle of the right side of the shrink box, corresponding to the position of the left connecting sleeve.

[0012] Preferably, a left pull cord hole is provided through the top of the front side of the left connecting sleeve, and a right pull cord hole is provided through the top of the front side of the right connecting sleeve.

[0013] Preferably, an elastic band pull rope is provided above the rear wash nylon sleeve and the front wash nylon sleeve. The left end of the elastic band pull rope passes through the left pull rope hole and wraps around the outer peripheral wall of the left connecting sleeve for fixation. The right end of the elastic band pull rope passes through the right pull rope hole and wraps around the outer peripheral wall of the right connecting sleeve for fixation.

[0014] The beneficial effects of this utility model are:

[0015] 1. A transmission drive unit is formed by coaxially fixing the rotary knob and the lower disc. The torque of the rotary knob is transmitted axially to the take-up shaft through the lower disc, driving the take-up shaft to achieve axial linkage with the upper disc. At the same time, the upper disc is rigidly connected to the rotating block, so that the rotating block performs circumferential limiting rotation within the rotating groove. The take-up shaft synchronously pulls the right end of the rear washing nylon sleeve and the front washing nylon sleeve through bidirectional winding, realizing synchronous extension and retraction adjustment of the two nylon sleeves under winding or unwinding conditions, thereby precisely controlling their opening distance, forming a closed-loop linkage adjustment system, and completing the adaptive matching of the cup size.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment: a portable adaptive cold-color changing cup sleeve, including a rear washable nylon sleeve 1; it also includes a front washable nylon sleeve 2, a shrink box 3, a shrink groove 4, a rotating groove 5, a take-up shaft 6, an upper disc 7, a rotating block 8, a lower disc 9, and a rotating knob 10. The front washable nylon sleeve 2 is located on the front side of the rear washable nylon sleeve 1. The shrink box 3 is located on the right side of the rear washable nylon sleeve 1 and the front washable nylon sleeve 2. The shrink groove 4 is located in the middle of the left side of the shrink box 3. The rotating groove 5 is located at the center of the top of the shrink box 3. The take-up shaft 6 is located at the center of the inside of the shrink box 3. The upper disc 7 is located at the top of the take-up shaft 6. The rotating block 8 is located at the center of the top of the upper disc 7. The lower disc 9 is located at the bottom of the take-up shaft 6. The rotating knob 10 is located at the center of the bottom of the shrink box 3. The lower disc 9 is rotated by rotating the knob 10. The rotating retractor 6 rotates, driving the upper disc 7 to rotate. The upper disc 7 then drives the rotating block 8 to rotate inside the rotating groove 5. Simultaneously, the retractor 6 retracts or unwinds the right ends of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2, thereby adjusting the size of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 after they are spread apart. This achieves an adaptive adjustment function, solving the problem of common portable adaptive cold-changing cup sleeves that only include heat insulation and cold insulation functions. While they can insulate the cup body from heat and cold, they lack adjustment functions and cannot guarantee that the size of the cup sleeve around the cup body can fit cups of different sizes. This can easily lead to a fixed cup sleeve size, where the cup sleeve cannot fit on larger cups, and when the cup sleeve is fitted on smaller cups, it cannot be firmly connected to the cup, affecting the cup sleeve's adaptability.

[0025] Please see Figures 2-6 In this embodiment, a right connecting sleeve 13 is provided at the middle of the right side of the shrink box 3, corresponding to the position of the left connecting sleeve 11. A left pull rope hole 12 is provided through the top of the front side of the left connecting sleeve 11, and a right pull rope hole 14 is provided through the top of the front side of the right connecting sleeve 13. An elastic pull rope 15 is provided above the rear wash nylon sleeve 1 and the front wash nylon sleeve 2. The left end of the elastic pull rope 15 passes through the left pull rope hole 12 and is wrapped around the outer peripheral wall of the left connecting sleeve 11 for fixation. The right end of the elastic pull rope 15... The end of the sleeve passes through the right pull cord hole 14 and wraps around the outer periphery of the right connecting sleeve 13 for fixation. Place the cup between the rear washable nylon sleeve 1 and the front washable nylon sleeve 2. The cup will spread the rear washable nylon sleeve 1 and the front washable nylon sleeve 2 apart. At this time, the rear washable nylon sleeve 1 and the front washable nylon sleeve 2 will be wrapped around the cup. When carrying, lift the cup sleeve with the elastic pull cord 15, and lift the cup with the cup sleeve. Then you can put the elastic pull cord 15 on your shoulder, which makes it convenient to carry the cup.

[0026] Please see Figures 1-6In this embodiment, the right ends of both the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 pass through the shrink groove 4 and are connected to the take-up shaft 6. The top of the rotating block 8 is inserted into the interior of the rotating groove 5. The top of the rotating knob 10 passes through the shrink box 3 and is connected to the bottom center of the lower disc 9. A left connecting sleeve 11 is provided on the left side of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2. The left ends of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 are sewn together with the left connecting sleeve 11. When it is necessary to put the cup sleeve ring on cups of different sizes, the lower disc 9 is rotated by rotating the knob 10. The lower disc 9 drives the take-up shaft 6 to rotate, and the take-up shaft 6 drives the upper disc 9 to rotate. The upper disc 7 rotates, and the upper disc 7 drives the rotating block 8 to rotate inside the rotating groove 5. At the same time, the winding shaft 6 winds up or loosens the right ends of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2, thereby adjusting the size of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 after they are spread apart. This achieves the function of adaptive adjustment and prevents the cup sleeve size from becoming fixed due to the lack of adaptive adjustment structure. When it is applied to a larger cup, it cannot achieve effective wrapping, while when it is applied to a smaller cup, the gap is too large and the fixation is unstable. The overall adaptability and versatility are significantly limited, and compatibility problems are easy to occur when adapting to cups of different sizes.

[0027] When working, place the cup between the rear wash nylon sleeve 1 and the front wash nylon sleeve 2. The cup will spread the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 apart, so that the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 are wrapped around the cup. When carrying, lift the cup sleeve with the elastic cord 15, and the cup sleeve will lift the cup. Then the elastic cord 15 can be slung over the shoulder, making it convenient to carry the cup. When it is necessary to wrap the cup sleeve around cups of different sizes, rotate the lower disc 9 by rotating the knob 10. The lower disc 9 drives the winding shaft 6 to rotate, which in turn drives the upper disc 7 to rotate. The upper disc 7 drives the rotating block 8 to rotate inside the rotating groove 5. At the same time, the winding shaft 6 winds up or loosens the right end of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2, thereby adjusting the size of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 after they are spread apart, realizing the function of adaptive adjustment.

[0028] Through the above steps, rotating the lower disc 9 by rotating the knob 10 causes the winding shaft 6 to rotate, which in turn causes the upper disc 7 to rotate. The upper disc 7 then causes the rotating block 8 to rotate inside the rotating groove 5. At the same time, the winding shaft 6 winds up or unwinds the right ends of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2, thereby adjusting the size of the rear wash nylon sleeve 1 and the front wash nylon sleeve 2 after they are spread out. This achieves the function of adaptive adjustment, solving the problem of common portable adaptive cold color-changing cup sleeves, which only have the functions of heat insulation and cold insulation. They can isolate the heat and cold of the cup body, but lack the function of adjustment. They cannot guarantee that the size of the cup sleeve around the cup body can be adapted to cups of different sizes. It is easy for the size of the cup sleeve to be fixed. When the cup sleeve is wrapped around cups of different sizes, the cup sleeve cannot be wrapped around the larger cups, and when the cup sleeve is wrapped around the smaller cups, it cannot be firmly connected to the cup, affecting the adaptability of the cup sleeve.
