Description

Technical Field

[0001] The utility model belongs to the technical field of water cups, and particularly refers to a threadless water cup. Background Technique

[0002] At present, as a tool for holding liquids in people's daily lives, water cups are very widely used. They can be seen everywhere, whether in the office, at school or in people's hands. Currently, most water cups on the market close the cup lid and the cup body together through threads, so that the inside of the cup is tightly closed and does not leak. When people close the cup lid, they need to hold the cup body with one hand and hold the cup lid with the other hand, and then use a little force with both hands to make the cup lid close tightly relative to the cup body. The same is true when opening the lid. When a driver is driving on a long-distance highway, if both hands are released to open or close the cup lid, there will be a safety hazard. Therefore, there is a need for a threadless cup that can be quickly closed with one hand without threads. Content of the Utility Model

The cup lid 2 includes a lower lid 21 and an upper lid 22. An inner support member 24 that cooperates with the step portion 11 is arranged inside the lower lid 21. A sealing ring 23 that cooperates with the sealing portion 12 is arranged at the lower end of the lower lid 21. The inner support member 24 includes a left support member 221, a right support member 222, and an elastic member 223. The elastic member 223 is located between the left support member 221 and the right support member 222, and the left support member 221 and the right support member 222 are always away from each other through the elastic member 223. Driving blocks 224 are arranged on both the left support member 221 and the right support member 222. A driving member 211 is arranged inside the upper lid 22. A driving inclined surface 225 that cooperates with the driving block 224 is arranged on the driving member 211. An avoidance groove 228 is arranged on the driving block 224. A blocking block 2111 is arranged on the driving member 211, and this blocking block 2111 is arranged close to the driving block 224. A ventilation hole 212 is arranged at the bottom of the lower lid 21. The lower end of the driving member 211 passes through the ventilation hole 212 and is connected with a sealing sleeve 213. By pressing the driving member 211, the left support member 221 and the right support member 222 can be controlled to approach each other, and the sealing sleeve 213 moves downward away from the ventilation hole 212, facilitating the cup lid to be separated from the cup body. A return spring 214 is arranged between the driving member 211 and the lower lid 21. Through the inner support member of the cup lid, it can be stuck on the step portion inside the cup body. Even if the cup lid is pulled hard, the inner support member cannot be separated from the step portion. And a sealing ring for cooperating with the sealing portion is arranged on the lower lid of the cup lid. The designed sealing ring can prevent the water inside the cup from flowing out. When it needs to be opened, only need to press the driving member downward. The driving member moves downward to control the left support member and the right support member to approach each other, and the left support member and the right support member are separated from the step portion. In this way, it is convenient for the cup lid to be separated from the cup body. The designed ventilation hole is for facilitating the internal air to communicate with the external air, and also for further facilitating the cup lid to be separated from the cup body; the designed driving block is for better facilitating the driving member to drive the left support member and the right support member to approach each other, ensuring that it can be smoothly separated from the cup body, and the designed avoidance groove is for facilitating a part of the driving member to pass through, avoiding interference with the driving block; it is worth mentioning that when the user accidentally pulls or pulls the cup lid hard, the left support member and the right support member will not approach each other due to the existence of the blocking block and thus cannot be separated from the step portion.

[0034] In the above-mentioned threadless water cup, two guiding inclined surfaces one 226 are arranged on the driving block 224, and an inclined surface 227 that cooperates with the guiding inclined surface one 226 is arranged on the blocking block 2111. Specifically, this is for further facilitating the driving member to drive the left support member and the right support member to approach each other. When the driving member rebounds and moves upward, the designed inclined surface can assist the left support member and the right support member to reset.

[0035] In the above-mentioned threadless water cup, the inclined surface 227 is arranged parallel to the driving inclined surface 225. Specifically, this is to facilitate the cooperation of the two guiding inclined surfaces of the driving block.

[0036] In the above-mentioned threadless water cup, a first sleeve 2211 and a first casing 2212 are arranged on the left support member 221, a second sleeve 2221 and a second casing 2222 are arranged on the right support member 222. The first sleeve 2211 is sleeved on the outside of the second casing 2222, and the second sleeve 2221 is sleeved on the outside of the first casing 2212. There are two elastic members 223, which are respectively located between the first casing 2212 and the second sleeve 2221 and between the first sleeve 2211 and the second casing 2222. The elastic member 223 is a spring. Specifically, this is to facilitate the left support member and the right support member to move away from each other under the elasticity of the spring. When the cup lid is matched with the cup body, the left support member and the right support member can be stuck on the step portion, and the left support member and the right support member can move synchronously. And a spring positioning rod is arranged in the sleeve.

[0037] In the above-mentioned threadless water cup, the driving member 211 is located between the first sleeve 2211 and the second sleeve 2221. Specifically, this is to avoid interference between the driving member and the first sleeve and the second sleeve and ensure the smoothness of the up and down movement of the driving member.

[0038] In the above-mentioned threadless water cup, a driving rod 2213 is arranged at the lower end of the driving member 211. A guiding tube 215 is arranged on the lower cover 21. The guiding tube 215 is located above the ventilation hole 212. The return spring 214 is located in the guiding tube 215 and is sleeved on the driving rod 2213. The two ends of the return spring 214 respectively abut against the step of the driving rod 2213 and the bottom of the guiding tube 215. Specifically, in this way, the driving member can always be away from the bottom of the cup under the action of the return spring, and the sealing sleeve always seals the ventilation hole.

[0039] In the above-mentioned threadless water cup, a second guiding inclined surface 111 is arranged on the step portion 11, and guiding surfaces 112 which are matched with the second guiding inclined surface 111 are arranged on the left support member 221 and the right support member 222. Specifically, the designed second guiding inclined surface and the guiding surface are to facilitate the connection between the cup lid and the cup body.

[0040] In the above-mentioned threadless water cup, a through groove 229 for a part of the driving member 211 to protrude is formed on the upper cover 22. A limiting ring 230 is arranged on the upper cover 22. The limiting ring 230 is located above the through groove 229. A hand-pulling ring 2110 is arranged above the driving member 211. A receiving groove 21101 for the hand-pulling ring 2110 to be embedded is arranged on the limiting ring 230. Specifically, the designed receiving groove is for the hand-pulling ring of the driving member not to protrude from the limiting ring when the cup cover and the cup body are fitted and connected, so as not to affect the user experience. The upper cover is provided with a recessed part, and the designed recessed part is for the convenience of the user to press the driving member. The recessed part is lower than the hand-pulling ring.

[0041] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
