Description

Technical Field

[0001] The utility model relates to the field of water cups, in particular to a portable water cup with variable capacity. Background Art

[0002] In daily life, water cups are commonly used drinking utensils. Traditional water cups usually have a fixed capacity, which has certain limitations in different usage scenarios. For example, when people travel, if they carry a large-capacity water cup, it will take up a lot of space in their backpack when they drink less water, causing inconvenience. On the other hand, if they carry a small-capacity water cup, it may not be able to meet their needs when they need to drink a lot of water.

[0003] In addition, in some special cases, such as when it is necessary to select the appropriate water cup capacity according to the amount of beverage, the traditional fixed-capacity water cup cannot meet this flexible demand. Therefore, it is of great practical significance to design a water cup with variable capacity, easy to carry and stable structure. Utility Model Content

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The capacity-variable portable water cup disclosed in the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2As shown, a portable water cup with variable capacity includes: a cup cover 1, a water cup shell 2, a water cup liner 3, a first guide rail 4, a second guide rail 5, a button 6, a button box 7, a first spring 8, a spring 9, a lock bolt 10, a first guide rail post 13, a second guide rail post 14, a second spring 15 and a sealing gasket 16, wherein:

[0034] The outer shell 2 and the inner liner 3 are both tubular structures. Both ends of the outer shell 2 are open, one end of the inner liner 3 is open, and the other end of the inner liner 3 is closed. The cup cover 1 closes one end of the outer shell 2, and the open end of the inner liner 3 slides along the end of the outer shell 2 away from the cup cover 1 and is embedded in the inner shell 2.

[0035] One end of the water cup liner 3 in an open state slides along the end of the water cup shell 2 away from the cup cover 1 and is embedded into the interior of the water cup shell 2, thereby realizing the telescopic movement of the water cup liner 3 in the water cup shell 2, thereby changing the capacity of the water cup;

[0036] The first guide rail 4 is provided on the water cup shell 2 to provide a guide for the sliding between the water cup shell 2 and the water cup liner 3, thereby ensuring the accuracy of the movement direction and making the entire extension and retraction process smoother and more stable.

[0037] The second guide rail 5 and the button box 7 are respectively arranged on the water cup inner liner 3, and the shell of the water cup housing 2 is inserted between the water cup inner liner 3 and the second guide rail 5, and between the water cup inner liner 3 and the button box 7;

[0038] The button 6 and the first spring 8 are respectively arranged inside the button box 7. The first spring 8 pushes the button 6 away from the button box 7. The button box 7 is provided with a plurality of through holes 11 on a side close to the water cup housing 2. The button 6 is provided with a plurality of protrusions 12 on a side close to the through holes 11.

[0039] The second spring 15, the spring 9 and the lock bolt 10 are respectively arranged between the button box 7 and the water cup housing 2. One side of the spring 9 is connected to the water cup housing 2. The lock bolt 10 is arranged on the spring 9 and is stuck in the inside of the through hole 11.

[0040] The first guide rail post 13 and the second guide rail post 14 are respectively arranged on the button box 7, and the first guide rail post 13 and the second guide rail 5 are respectively clamped inside the sliding groove of the first guide rail 4;

[0041] The second spring 15 is provided between the spring piece 9 and the water cup housing 2 , and the second spring 15 pushes the spring piece 9 and the lock bolt 10 away from the water cup housing 2 ;

[0042] The sealing gasket 16 is provided at the edge of one end of the water cup liner 3 in an open state;

[0043] The cup cover 1 is fixed to the threaded opening 17 of the cup housing 2 by screw connection;

[0044] The inner liner 3 of the water cup is made of silicone, and the spring 9 is made of metal;

[0045] Four through holes 11 are provided on one side of the button box 7 close to the water cup housing 2 , and four protrusions 12 are provided on one side of the button 6 close to the through holes 11 .

[0046] Specifically, when the capacity of the water cup needs to be increased, the user first presses the button 6 inward. The button 6 overcomes the elastic force of the first spring 8 and moves toward the inside of the button box 7. At this time, the position of the protrusion 12 on the button 6 and the through hole 11 change relative to each other. The protrusion 12 squeezes the lock bolt 10, causing the lock bolt 10 to disengage from the through hole 11. During this process, the spring 9 will be deformed to a certain extent.

[0047] Next, the user can pull the water cup liner 3 and slide it outward along the first guide rail 4 until the desired capacity position is reached, and then release the button 6. Under the action of the first spring 8, the button 6 is reset, and the lock bolt 10 is re-engaged in the through hole 11 at the corresponding position under the joint action of the spring 9 and the second spring 15, locking the water cup liner 3 in this position, thereby achieving capacity increase adjustment;

[0048] In addition, when the capacity of the water cup needs to be reduced, the operation process is similar. The button 6 is pressed inward to disengage the lock bolt 10 from the through hole 11, and then the water cup liner 3 is pushed inward along the first guide rail 4. After adjusting to the appropriate position, the button 6 is released, and the lock bolt 10 is locked into the through hole 11 again, completing the capacity reduction adjustment;

[0049] When the temperature rises, the expansion degree of the water cup liner 3 is greater than that of the water cup shell 2. When the temperature drops, the contraction degree of the water cup liner 3 is less than that of the water cup shell 2.

[0050] Specifically, when hot water is contained, the inner liner 3 of the water cup expands outward, but because its expansion is greater than that of the outer shell, no gap will appear between the inner liner and the outer shell due to squeezing, thereby avoiding water leakage. When cold water or drinks with lower temperatures are contained, the inner liner contracts relatively little and can still maintain a good fit with the outer shell, ensuring the stability of the overall structure of the water cup.

[0051] To sum up, the capacity-variable portable water cup disclosed by the utility model has, on the one hand, an adjustable cup volume, and the inner liner of the water cup can be slid and embedded along the outer shell. The user can flexibly change the internal space of the water cup as needed to achieve capacity adjustment, thereby improving practicality and applicability. On the other hand, it is convenient to carry when going out. When going out, the inner liner of the water cup can be retracted to reduce the volume of the water cup, making it easy to place in a limited space such as a backpack, making travel more convenient. Finally, it has a stable structure after adjustment. Through the cooperation of guide rails, buttons, springs, lock bolts and other components, the lock bolt is stuck in the through hole after adjustment to prevent the inner liner from sliding due to external force. The guide rails provide guidance to ensure the stability of the water cup structure and avoid capacity changes.

[0052] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
