[0021] As a further scheme of the utility model: the key is flush with the port of the outer frame.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. Through the linkage design of the key, the transmission assembly and the moving block, the "one-key pressing unlocking" is realized, the operation is convenient and conforms to the single-hand use habit; in the pressing process, the axial movement of the key is converted into the radial movement of the moving block, the operation force is reduced, the cumbersome operation of the traditional screw knob is avoided, the overall structure is compact, single-hand operation is suitable, and the utility model is especially suitable for use in the scenes such as sports.

[0024] 2. The detachable design of the outer frame and the cylinder body facilitates cleaning and maintenance, avoids the accumulation of dirt at the sliding fit between the plug and the built-in cylinder. The axial sliding of the plug ensures the accuracy of the movement track of the key, prevents deviation or jamming, the first reset member gives the key an automatic reset function, and the operation continuity is improved. The abutment between the convex part and the stop convex rib limits the maximum stroke of the key reset.

[0025] 3. The cooperation design of the pin and the silica gel ring cleverly balances the sealing and ventilation requirements: under normal circumstances, the silica gel ring seals the gap between the pin and the closed end, preventing liquid from seeping into the cup cover; when the key is pressed, the silica gel ring moves with the pin to open the gap, realizing the balance of the air pressure in the cup, avoiding the "difficult opening" problem caused by negative pressure when opening the cover. In addition, the silica gel ring has the functions of leakage prevention and buffering, prolonging the service life of the transmission component.

[0026] 4、Multiple circumferential array of moving blocks are linked by U-shaped links, evenly dispersing the unlocking pressure, avoiding wear or failure caused by single-point stress, and improving the stability of the clamping. The cylindrical structure formed by the U-shaped links enhances the overall rigidity, preventing stress deformation; at the same time, this design can adapt to different sizes of cup ring annular steps by increasing or decreasing the number of moving blocks, improving product versatility. The coaxial layout of the cylindrical structure and the built-in cylinder optimizes space utilization, ensuring compact structure.

[0027] 5、The cooperation of the inclined wedge surface and the inclined groove realizes two-stage motion conversion: the axial pressing of the key drives the rotating disc to rotate through the inclined wedge surface, and the rotating disc inclined groove further converts the rotating motion into the radial displacement of the moving block, with high transmission efficiency and low friction loss. The cooperation of the convex column and the inclined groove can accurately control the displacement of the moving block, ensuring the reliability of the unlocking action; the coaxial design of the rotating disc and the column pin reduces the radial space occupation, is suitable for small-sized cup cover structure, and at the same time reduces the assembly complexity.

[0028] 6、The slot hole provides a standardized mounting position for the driven wedge block, ensuring the position of the component during the cooperation of the inclined wedge, avoiding deviation or falling caused by vibration or impact, and improving the transmission stability. The design of the slot hole extending to the inside of the rotating disc limits the movement range of the driven wedge block, reducing wear; at the same time, this structure is convenient for production and assembly, reduces the processing precision requirement, and is conducive to cost control.

[0029] 7、The second reset member stores energy when pressed, and drives the rotating disc to reset after the key is released, ensuring that the moving block automatically recovers to the clamping state and avoiding manual adjustment. The double-reset system composed of the first reset member and the second reset member works cooperatively, ensuring smooth key rebound and avoiding rotating disc reset lag, improving operation reliability. The elastic energy storage characteristics of the torsional spring can buffer the pressing impact force, optimize the feel, and prolong the service life of the mechanism.

[0030] 8、The combination design of the clamping ring and the detachable sealing ring strengthens the sealing performance of the cup mouth, preventing liquid from leaking from the contact surface between the cup cover and the cup body. The flexible contact between the sealing ring and the inner wall of the cup body adapts to different cup body tolerances, improving compatibility; the detachable structure facilitates the replacement of aged sealing rings, reducing maintenance costs. The fixed installation of the clamping ring ensures that the sealing ring does not displace during long-term use, avoiding sealing failure caused by frequent opening of the cover.

[0031] 9、Spring and torsional spring are used as standard reset members, with low cost and stable performance, suitable for mass production. The spring provides linear reset force, ensuring quick rebound of the key; the rotational energy storage characteristics of the torsional spring are highly matched with the rotating disc reset requirement, avoiding the complexity of the supply chain caused by customized parts. The combination of the two standard parts simplifies the design, reduces the failure rate, and is convenient for later maintenance and replacement.

[0032] 10. The key is flush with the outer frame port design to improve the overall appearance, avoid the convex structure affect the comfort or scratch other items. Flush layout effectively prevent external objects (such as the key in the bag, stationery) mis-touch the key to cause accidental cover, enhance the use of safety. In addition, the flat surface is easier to clean, meet the dual needs of modern consumers for product aesthetics and practicality. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0049] As shown in the figure, a one-key cover opening water cup, comprising a cup body 1 and a cup cover 2 used for covering the cup body 1, compared with the threaded connection mode of the cup body 1 and the cup cover 2 in the prior art, the application sets the cup cover 2 and the cup body 1 in a clamping mode, and the locking of the cup cover 2 on the cup body 1 can be released by pressing the button 4 on the cup cover 2, which is convenient to use. Figures 1-13 Specifically, the cup cover 2 comprises a cylinder body 3 and an outer frame 6, the cylinder body 3 has an open end 301 and a closed end 302, a plurality of key blocks 19 are arranged in an array around the open end 301 of the cylinder body 3, a plurality of clamping grooves 20 are arranged in an array around the inner side of the outer frame 6, the plurality of key blocks 19 are arranged one by one corresponding to the plurality of clamping grooves 20, the installation of the outer frame 6 on the cylinder body 3 is realized by the cooperation of the key blocks 19 and the clamping grooves 20, and the state after installation can be represented by

[0050] Figure 5 The outer frame 6 has a built-in cylinder 601 inside the cylinder body 3, and the built-in cylinder 601 is coaxially arranged with the cylinder body 3, a plurality of extension parts are arranged in an array around the inner side of the built-in cylinder 601, a through hole is arranged on each extension part, an insertion bar 603 is slidably installed in the through hole in the axial direction, one end of the plurality of insertion bars 603 close to the open end 301 is commonly installed with the button 4, and the connection structure of the plurality of insertion bars 603 and the button 4 can be represented by Figure 10 ​When the button 4 is pressed downward, the plurality of insertion bars 603 will slide axially in the corresponding through holes, cooperating with the movement of the button 4. In order to prevent the button 4 from being separated from the barrel 3, a stop protrusion 602 is fixedly arranged on the inner wall of the built-in barrel 601, and a protrusion 604 is arranged on the side of the insertion bar 603, which can move axially with the insertion bar 603. The stop protrusion 602 is located in the linear motion path of the protrusion 604. When the button 4 is moved upward to the position where the protrusion 604 on the button 4 abuts against the stop protrusion 602, the button 4 is in the final state of upward movement, which ensures that the button 4 will not be separated from the barrel 3.

[0051] Further, in order not to accidentally press the button 4 downward, the button 4 is preferably flush with the outer frame 6, and this flush state can be represented by Figure 5 In order to always maintain the flush state of the button 4 and the outer frame 6, a first reset member (preferably a spring) 7 is arranged on the closed end 302 of the barrel 3 and fixedly connected with the button 4. The first reset member 7 is used to make the button 4 have a movement tendency towards the opening end 301. Under this movement tendency, the first reset member 7 exerts an upward pushing force on the button 4, so that the protrusion 604 on the insertion bar 603 will always abut against the stop protrusion 602, achieving the flush arrangement of the button 4 and the outer frame 6. At the same time, under the arrangement of the first reset member 7, when the downward pressing action on the button 4 is released, the button 4 can be reset upward to the flush state with the outer frame 6.

[0052] A plurality of moving blocks 5 are arranged in a circumferential array near the closed end 302 of the barrel 3. One end of each moving block 5 extends to the outside of the barrel 3 and is arranged in a radial direction. This state can be represented by Figure 5 Two adjacent moving blocks 5 are connected by a U-shaped connecting rod 10, and a plurality of U-shaped connecting rods 10 jointly enclose a cylindrical structure. This structure can be represented by Figure 13 Under this cylindrical structure, each moving block 5 can be driven to move elastically in the radial direction, that is, the plurality of moving blocks 5 can be driven to move towards the inside of the barrel 3 in the state shown in Figure 5

[0053] For the design of the cup body 1, an annular step 101 is arranged at the inner wall of the cup opening of the cup body 1, as shown in Figure 3 ​In the shown state, the plurality of moving blocks 5 all extend to the outside of the barrel 3, and the diameter of the virtual circle formed by the plurality of moving blocks 5 is greater than the diameter of the cup mouth. If it is necessary to install the cup cover 2 on the cup body 1, at this time, the plurality of moving blocks 5 can be driven to retract into the barrel 3, and then the barrel 3 is driven to move downward until the barrel 3 is inserted into the designated position of the cup mouth. The closed end 302 at the bottom of the barrel 3 is fixedly provided with a snap ring 18, and a sealing ring 13 is detachably mounted on the snap ring 18. During the process of inserting the barrel 3 into the cup mouth, the sealing ring 13 is deformed under the pressure of the inner wall of the cup mouth, thereby achieving the circumferential sealing of the cup mouth. Then, one end of each of the plurality of moving blocks 5 extends out of the barrel 3. At this time, the end of the moving block 5 is located below the annular step 101 and is in an upper and lower abutting state with the annular step 101, thereby completing the locking of the barrel 3 on the cup mouth. This state can be represented by Figure 2 . Subsequently, the plurality of moving blocks 5 are driven to retract into the barrel 3, thereby releasing the abutting state of the moving blocks 5 and the annular step 101, and the cover opening operation is performed.

[0054] In order to automatically ventilate during the above-mentioned cover opening operation, a column pin 8 is fixedly provided on the button 4. One end of the column pin 8 movably penetrates the closed end 302. As shown in the state Figure 9 , a silica gel ring 9 is sleeved at the bottom end of the column pin 8 to seal the gap between the column pin 8 and the closed end 302. In the closed state Figure 2 , the cup cover 2 is sealed with the cup body 1 through the sealing ring 13 and the silica gel ring 9. During the cover opening process of pressing the button 4 downward, the downward movement of the button 4 can drive the column pin 8 and the silica gel ring 9 to move downward. At this time, the gap between the column pin 8 and the closed end 302 is opened, and the inside of the cup body 1 can be communicated with the outside.

[0055] In order to automatically drive the plurality of moving blocks 5 to move into the barrel 3 during the pressing of the button 4, that is, to achieve the unlocking of the cup cover 2, a transmission assembly is arranged in the barrel 3. The transmission assembly is located between the button 4 and the closed end 302. The downward movement of the button 4 can drive the plurality of moving blocks 5 to move close to each other through the transmission assembly. As follows, the transmission assembly is described:

[0056] As shown in Figures 10-12 , the transmission assembly includes a rotating disc 11 coaxially arranged on the column pin 8, and a driven wedge 12 is fixedly arranged on the rotating disc 11. On the basis of arranging the insertion strip 603, an inclined wedge surface is arranged at the bottom end of the insertion strip 603 to enable the end to be inclined and matched with the driven wedge 12, so as to realize the rotary motion of the rotating disc 11 when the button 4 is pressed to move towards the closed end 302. One end of the moving block 5 fixedly arranged in the barrel 3 is provided with a protruding column 14, and an inclined slot 15 is arranged on the rotating disc 11 for the protruding column 14 to penetrate. The inclined slot 15 is arranged non-radially on the rotating disc 11. The specific arrangement form can be represented by Figure 11To be expressed, when the press button 4 moves towards the closed end 302, the convex column 14 is driven to move radially towards the pivot pin 8 by the rotary action of the inclined groove 15, the moving block 5 moves away from the annular step 101, that is, the movement of the plurality of moving blocks 5 moving close to each other, and the unlocking is realized.

[0057] Further, as shown in Figure 11 In order to facilitate the larger radial movement of the plug strip 603, a slot hole 16 is formed on the rotating disc 11 for mounting the driven wedge block 12, and the inclined wedge surface of the driven wedge block 12 extends into the slot hole 16, so that the bottom end of the plug strip 603 can be inserted into the slot hole 16 and wedge with the driven wedge block 12. Of course, as shown in Figure 9 In order to better reset the moving block 5 to the initial state after the press button 4 is reset upward, the transmission assembly further comprises a second reset member (preferably a torsional spring) 17 arranged on the pivot pin 8, and the second reset member 17 is located between the rotating disc 11 and the closed end 302. When the press button 4 moves towards the closed end 302, the second reset member 17 is used to store energy for the rotary action of the rotating disc 11, and subsequently when the press button 4 is released, the second reset member 17 drives the rotating disc 11 to reset the rotary action, and then drives the convex column 14 to reset through the inclined groove 15, so as to reset the moving block 5. Even if the moving block 5 is arranged on the cylindrical structure, it can be reset by its own material elasticity, but the addition of the second reset member 17 can obviously better exert the radial reset action on the moving block 5, and can quickly and accurately reset the moving block 5 to the state shown in Figure 5 .

[0058] It should be noted that the transmission assembly provided by the present application realizes the driving action of the press button 4 on the plurality of moving blocks 5, and in actual use, the transmission assembly is not limited to the structure shown in the present application, but can also be other conventional technical means in the prior art. The design of the transmission assembly in the present application is not limited.

[0059] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
