Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a water cup without threads. Background Art

[0002] It is known that a water cup is a container for holding drinking water for the convenience of users. Existing water cups are generally sealed with threaded bottle stoppers or solid rubber stoppers, which are inconvenient in daily use, especially when users are driving or climbing outdoors. The threaded cup has high requirements for users. Users need to use both hands to open the lid, and it cannot be opened quickly. If the user is driving or climbing at a high speed, the user cannot drink water. Therefore, how to design a water cup with a non-threaded lid and can open the lid quickly has attracted attention. Therefore, a Chinese utility model patent with authorization announcement number CN220494757U appeared, which disclosed a non-threaded water cup, which included a cup body and a cup cover, and the cup cover was detachably connected to the cup body; the cup cover was provided with a sealing ring, and when the cup cover was installed on the cup body, the sealing ring pressed against the cup body; a plurality of holes were provided on the side of the cup cover, and a plurality of round balls were movably provided in the holes, and the round balls could not completely pass through the holes; a limiting groove was provided on the inner side of the cup body, and a movable part was provided inside the cup cover, and the movable part could press against the round balls and keep part of the round balls passing through the cup cover naked In the exposed state, the exposed part of the ball is located in the limit groove, thereby limiting the detachment of the cup cover from the cup body; the movable part is driven, the movable part moves and forms an escape space, the ball can be placed in the escape space, the ball can be detached from the limit groove, and the cup cover can be detached from the cup body. Although this also ends the threaded connection method, the ball must be able to not detach from the cup cover, but also be able to be engaged in the limit groove on the inner side of the cup body. This structure is relatively complicated, which increases the difficulty of production and manufacturing, and is not conducive to mass production of manufacturers. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0039] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A non-threaded water cup comprises a cup body 1 for holding drinking water and a cup cover 2 arranged on the opening of the cup body 1, wherein the cup cover 2 comprises a base 21 and an upper cover 22 arranged on the upper part of the base 21, a lower seat 23 sliding up and down along the base 21 is arranged at the lower part of the base 21, a reset member 24 is arranged between the lower seat 23 and the base 21, a locking member 25 for locking on the opening of the cup body 1 is arranged on the base 21, a first through hole for the locking member 25 to enter and exit is arranged on the base 21, and a locking member 25 for locking on the opening of the cup body 1 is arranged on the base 21, and a locking member 25 for locking on the lower seat 23 is arranged on the lower seat 23. A second perforation is provided for the locking member 25 to enter and exit. After the first perforation and the second perforation overlap with each other, the locking member 25 can enter and exit, and an unlocking mechanism 26 for unlocking the locking member 25 is provided on the base 21. A card slot 11 is provided on the inner wall of the opening of the cup body 1. The locking member 25 is inserted into the card slot 11 to realize that the cup cover 2 is tightly covered on the opening of the cup body 1. When the unlocking mechanism 26 is activated, the unlocking mechanism 26 will withdraw the locking member 25 from the card slot 11 to realize that the cup cover 2 can be removed from the opening of the cup body 1.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, specifically, when in use, first place the cup cover 2 on the opening of the cup body 1, and then press the upper cover 22, so that the upper cover 22 will cause the base 21 and the lower seat 23 to slide relative to each other to achieve the first perforation and the second perforation overlap with each other, which is conducive to the locking member 25 sliding out and locking in the slot 11, so that the cup cover 2 is tightly covered on the opening of the cup body 1; and when the unlocking mechanism 26 is pressed, the unlocking mechanism 26 will compress the locking member 25, so that the locking member 25 will withdraw from the slot 11, and at the same time, when the reset member 24 is reset, the first perforation and the second perforation are misaligned with each other, and finally the locking member 25 is located inside the base 21, which is conducive to the user to remove the cup cover 2 from the opening of the cup body 1.

[0041] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 and Figure 5 As shown, a sealing ring 27 is provided at the lower part of the lower seat 23, and the sealing ring 27 is sealed and connected with the opening of the cup body 1, which is conducive to improving the sealing of the cup cover 2 on the opening of the cup body 1, and is more conducive to meeting the use requirements. It is to be noted that the sealing ring 27 is sleeved at the lower part of the lower seat 23, which is convenient for implementation.

[0042] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the locking member 25 includes sliders 251 arranged in pairs on the base 21, and a compression member 252 is arranged between the sliders 251 arranged in pairs. A through hole 253 is arranged on the slider 251, and a side wall of the through hole 253 is provided with an upper inclined surface 254 and a lower vertical surface 255. The unlocking mechanism 26 moves in the through hole 253 to cause the sliders 251 arranged in pairs to shrink inwardly, thereby causing the compression member 252 to perform a compression effect. When the compression member 252 is reset, it is beneficial to realize the outward expansion of the sliders 251 distributed in pairs. Each slider 251 is provided with a clamping portion 256 that matches the slot 11. This arrangement is reasonable, simple in structure, and easy to implement. The slider 251 can enter and exit from the first perforation and the second perforation, which is beneficial to realize the slider 251 being clamped into or withdrawn from the slot 11. The number of sliders 251 is at least two, and may be an odd number (in this case, there may be compression members 252 and seats for resisting the compression members 252 that are consistent with the number of sliders 251, which is conducive to the slider 251 compressing the compression member 252 and facilitating its reset). It should be noted that the compression member 252 is a spring, which has a wide range of sources and is easy to implement.

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, specifically, the unlocking mechanism 26 includes a connecting frame 261 disposed inside the base 21 and capable of moving up and down. The lower end of the connecting frame 261 enters the through hole 253 along the upper inclined surface 254 and the lower vertical surface 255, causing the slider 251 to contract inward. When the lower end of the connecting frame 261 moves upward from the through hole 253 along the lower vertical surface 255 and the upper inclined surface 254, the slider 251 is urged to expand outward when the compression member 252 is reset. A return member 262 is provided between the lower bottom surface of the connecting frame 261 and the base 21. The connecting frame 261 can be returned after being compressed through the return member 262. The lower end surface of the connecting frame 261 that cooperates with the upper inclined surface 254 is a lower inclined surface 263. A switch button 264 for starting the downward movement of the connecting frame 261 is provided on the upper cover 22. A restoring member 265 is provided on the switch button 264. An installation groove 266 for urging the switch button 264 to move downward after being activated is provided on the connecting frame 261. The movement of the switch button 264 in the installation groove 266 will cause the connecting frame 261 to move downward. When the external force on the switch button 264 is removed, the switch button 264 is restored to its original state under the action of the restoring member 265.

[0044] As shown in Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the connecting frame 261 is in an inverted "U" shape. The lower end surfaces of the two feet of the inverted "U" shaped connecting frame 261 are both provided with lower inclined surfaces 263. An installation groove 266 is provided on the upper end surface of the inverted "U" shaped connecting frame 261. In this embodiment, there are two installation grooves 266. The installation groove 266 includes a lower inclined surface 2661 and an upper horizontal surface 2662. The switch button 264 includes a door-shaped main body. The two feet of the door-shaped main body are both inclined. When the two feet of the main body move into the corresponding installation grooves 266, the connecting frame 261 will be caused to move downward. A restoring member 265 is provided between the positions of the two feet of the main body. One end of the restoring member 265 is fixedly provided with the main body, and the other end of the restoring member 265 is in contact with the upper cover 22. This is beneficial for the switch button 264 to automatically return after the external force is removed.

[0045] As shown in Figure 5 , a jacket 267 is provided on the connecting frame 261. The connecting frame 261 moves up and down in the jacket 267, and the return member 262 is located between the lower bottom surface of the jacket 267 and the connecting frame 261. This is beneficial for the up and down movement of the connecting frame 261.

[0046] As shown in Figure Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, an exhaust valve 268 is provided on the connecting frame 261, and the exhaust valve 268 passes downward from the base 21 through the lower seat 23, which is conducive to exhausting the inside of the base 21 and the lower seat 23, which is more conducive to the mutual sliding of the base 21 and the lower seat 23. It is to be noted that the exhaust valve 268 includes a row of needles 2681 integrally provided on the connecting frame 261, and an exhaust rod 2682 is provided on the row of needles 2681, and an exhaust spring 2683 and a silicone ring 2684 are provided on the exhaust rod 2682, and an exhaust spring 2683 is provided on the exhaust rod 2682 above the silicone ring 2684, and this arrangement is easy to implement.

[0047] Among them Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the return member 262 and the restoring member 265 are both springs, which are widely available and easy to implement.

[0048] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the reset member 24 includes a fixed column 241 arranged on the inside of the lower seat 23 and a sleeve column 242 arranged on the inside of the base 21. The fixed column 241 is correspondingly installed in the sleeve column 242, and a reset spring 243 is arranged between the fixed column 241 and the sleeve column 242. This is conducive to compressing the reset spring 243 when the base 21 and the lower seat 23 move relative to each other, so as to facilitate resetting the base 21 and the lower seat 23 through the reset spring 243. In this embodiment, the fixed column 241 and the lower seat 23 are integrally formed, and the sleeve column 242 and the base 21 are integrally formed, which greatly enhances the firmness. It is also worth noting that the fixed column 241, the sleeve column 242 and the reset spring 243 are all four, which is more conducive to the smooth reset of the base 21 and the lower seat 23 through the reset spring 243.

[0049] Embodiment 5: It can be described on the basis of Embodiment 3 or Embodiment 4, such as Figure 2 , Figure 3 and Figure 5 As shown, the upper cover 22 includes a cover body 221 disposed on the base 21, a handle 222 is disposed on the upper end of the cover body 221, and a frame 223 is disposed between the cover body 221 and the outer cover 267. This arrangement is more conducive to pressing the upper cover 22, and then the upper cover 22 causes the base 21 and the lower seat 23 to move relative to each other, and the handle 222 is convenient for the user to remove the cup cover 2. It is to be noted that the cover body 221 and the handle 222 are integrally arranged, which improves the structural firmness.
