[0040] 2023—internal thread; 203—sealing ring; Specific implementation method:

[0041] Reference Figures 1 to 8 , a button-operated cup with lid 100 suitable for one-hand operation, including a detachable cup lid 100 and a cup body 200, so that the cup body 200 can provide drinking water and cleaning. In this example, the cup body 200 is a double-body structure, including a cup body 201 and a connecting sleeve 202 fastened to the cup body, and the two are tightly matched with threads; an inner convex ring 2021 is formed on the upper edge of the connecting sleeve 202, a step portion 2022 is formed in the middle, and an inner thread 2023 that matches the cup body is formed on the lower edge. The upper surface of the connecting sleeve step portion 202 is used for the sealing ring on the sealing bracket to contact and seal, and the bottom surface is used for contact and seal with the opening of the cup body 201 with the help of the sealing ring 203. The double-rest structure can simplify the molding process of the cup body 201, so that more materials can be used, such as stainless steel or glass; and the upper mouth of the connecting sleeve is the cup mouth for drinking.

[0042] The cup cover 100 includes a cover body 1, an upper bracket 2, a sliding bracket 3, a sealing bracket 4, a pair of locking tongues 5 and a button 6; the upper bracket 2, the sliding bracket 3 and the sealing bracket 4 are distributed and installed on the inner side of the cover body 1 in sequence from top to bottom, the upper bracket 2 is locked with the sliding bracket 3, the sealing bracket 4 is arranged under the sliding bracket 3, and with the help of a sealing ring 7 embedded in the ring edge, it abuts on the cup body 200, that is, it abuts on the step portion 2022 of the connecting sleeve to form a sealing effect.

[0043] A pair of locking tongues 5 are slidably arranged in the slideway formed by the upper bracket 2 and the sliding bracket 3, that is, they are constrained between the two and can only slide radially; and under the action of the locking spring 54, they always maintain a tendency to resist the inner convex ring 201 of the cup mouth, that is, the radial spring force of the locking spring 54 drives the two locking tongues 5 to open outward, and they can be popped out in real time and be stuck by the inner convex ring 201.

[0044] The button 6 is arranged in the central hole 11 of the cover body 1 and is constrained to move only up and down. The button 6 passes through the upper bracket 2 and the sliding bracket 3 in sequence. The driving inclined surfaces 61 on both sides thereof correspondingly abut against a pair of locking tongues 5, and the downward movement can drive the pair of locking tongues 5 to retract inward; a rotatable locking mechanism 8 is arranged on the cover body 1, and the locking mechanism 8 constrains the action of the button 5.

[0045] The following is a further description of the specific structure of each component in conjunction with specific diagrams:

[0046] The lock tongue 5 has an arc lock head 51 and a sliding tongue handle 52. A notch 53 is provided in the middle of the sliding tongue handle. The sliding tongue handles 52 of a pair of lock tongues overlap and slide up and down, that is, the contact surfaces of the two are provided with slideways, which constrain them to slide linearly. The locking spring 54 is arranged between the bottom of the notch 53 of one lock tongue and the end of the sliding tongue handle 52 of the other lock tongue, so as to maintain the radial opening trend of the two lock tongues 5. The overlapping part of the notch 53 of the two lock tongues is inserted by the central column 62 of the key, and the driving inclined surfaces 61 on both sides of the central column 62 correspondingly contact the inner edges of the notches 53 of the two lock tongues, driving the lock tongues 5 to retreat. The central column 62 of the key cooperates with the inner edges of the two overlapping notches 53 to play a guiding role. When the key 6 loses external force, the locking spring 54 can not only make the two lock tongues 5 open outward quickly, but also react to the driving inclined surface 61 of the key by the edge of the notch 53, so that the key 6 moves up to the initial position and waits for the next unlocking task.

[0047] like Figure 2 and Figure 3 The cover body 1 has a circular boss 11 in the center and an annular step surface 12 on the outer edge. A central hole 13 for setting the key 6 is opened on the circular boss 11, and a hollow groove 14 is formed at the intersection of the circular boss 11 and the annular step surface 12; the key 6 has a central column 62 and a key cap 63 that matches the central hole 13, and driving inclined surfaces 61 are formed on both sides of the central column 62. In order to facilitate the cooperation with the notch 53 of the lock tongue, the cross-section of the central column 62 is a square structure; pins 64 are distributed on the lower edge of the key cap 63, and the lower end of the pin 64 has an outward hook 641, which can be hung on the inner edge of the central hole 13 of the cover body with the help of the outward hook 641 to prevent it from falling out.

[0048] The locking mechanism 8 comprises an upper locking ring 81 and a locking ring 82, and a pair of positioning ears 821 are arranged on the radial edge of the locking ring 82; the upper locking ring 81 is sleeved on the annular step surface 12 of the cover body, just covering the corner space between the annular step surface 12 and the edge of the circular boss 11, forming an organic decoration that is convenient for adjustment operation; the locking ring 82 is arranged on the inner side of the circular boss 22, and its radial pair of positioning ears 821 passes through the hollow groove 14 and is screwed to the bottom of the upper locking ring 81, that is, the locking ring 82 is in a hanging structure and can rotate with the upper locking ring 81; a stopper 822 corresponding to the key pin is distributed on the inner edge of the locking ring 82, and a small movement gap is formed between the surface of the stopper 822 and the bottom of the pin 64, which also includes the outward extension hook 641 of the pin; the stopper 822 can enter and leave the bottom of the positive projection of the pin 64 as the upper locking ring 81 rotates, blocking or releasing the downward constraint of the key 6, thereby switching the key 6 safety on and off to avoid accidental touch. In addition, although the lock ring 82 is suspended and positioned by the upper locking ring 81, a pair of symmetrical arc enclosures 23 are protruding upward on the surface of the upper bracket 2, which can also be used to restrict the rotation of the lock ring 82 and the rotation range of the two positioning ears 821. Moreover, the top of the arc enclosure 23 is abutted against the circular boss 11 of the cover body to improve the correlation between the parts, such as Figure 5 , Figure 6 and Figure 8 .

[0049] like Figure 2 Two pairs of symmetrical arc blocking pieces 15 are formed on the annular step surface of the cover body, and each pair of arc blocking pieces has a corrugated convex portion 151 protruding inwardly at the distal end thereof, and the arc blocking piece with the corrugated convex portion 151 is suspended in the hollow groove 14 of the annular step surface 12, so that the arc blocking piece 15 has a certain elastic deformation ability; the upper locking ring 81 is provided with an arc stop piece 811 corresponding to the arc blocking piece 15, and the outer surface of the arc stop piece 811 is formed with a corrugated ripple 812, and when assembled in place, the corrugated convex portion 151 can slide into the corrugated ripple 812 to form an adjustment gear. More specifically, two corrugated convex portions 151 are provided on each pair of arc blocking pieces 15, providing a more balanced resistance and increasing the adjustment feel. The wavy pattern 812 of the arc stopper piece 811 corresponds to the stopper 822 being directly below the pin 64 and completely away from the position. Two high ripples 813 are also provided, which are configured with the convex wave 151 to form an obvious resistance feel during the adjustment process to remind the switching state of the safety switch. Because the convex wave 151 is at the suspended end of the arc stopper piece 15, it is ensured that the locking ring 81 has both resistance and good passability when rotating and adjusting.

[0050] Furthermore, the cover body has a plurality of inclined surface protrusions 111 distributed on the outer surface of the circular boss 11, and the inner surface of the lower edge of the arc stopper 811 of the upper locking ring is provided with corresponding inclined surface chamfers 814, which are used to slide over the inclined surface protrusions 111 to form assembly constraints and provide multi-point support during rotation adjustment. More specifically, the matching inclined surface protrusions 111 and the inclined surface chamfers 814 are matched at a 45-degree angle, which not only ensures the reliability of positioning, but also allows the upper locking ring 1 to be separated by hand for easy cleaning. Furthermore, a pair of symmetrical elastic clamping arms 31 are arranged upward on the edge of the sliding bracket 3, and the ends of the elastic clamping arms 31 have an outward clamping portion 311 and an inclined top portion 312; when assembling, the elastic clamping arms 31 pass upward through the recess 24 reserved on the edge of the upper bracket 2, and the inclined top portion 312 slides over the outer edge of the hollow groove 14 of the cover body to compress the elastic clamping arms 31 to deform inward, and then the clamping portions 311 are placed on the annular step surface 12 of the cover body to form a detachable positioning. When cleaning, first remove the upper locking ring 81, and then pinch the two inclined top portions 312 with two fingers to force the elastic clamping arms 31 to retract, and the upper bracket 2, the sliding bracket 3 and the sealing bracket 4 can be separated from the cover body 1 as a whole, providing convenience for internal cleaning.

[0051] In addition, the upper bracket 2 is provided with an arc-shaped guide surface 25 protruding upward, and the arc-shaped guide surface 25 is attached to the inner surface of the circular boss 11 of the cover body to play a guiding role during disassembly and assembly, and to keep the sealing bracket 4 centered.

[0052] The bottom surface of the upper bracket 2 is formed with two slide baffles 21, and the lower edges of the two slide baffles 21 are against the surface of the sliding bracket 3 to form a slideway for the lock tongue 5 to slide; the lower edges of the two slide baffles 21 are formed with inclined hooks 22 facing outward, and the surface of the sealing bracket 4 is provided with hooks 41 corresponding to the inclined hooks 22. When assembled in place, the two hooks 41 are hung on the corresponding inclined hooks 22 to form an anti-slip structure, while allowing the sealing bracket 4 to float appropriately; a sealing spring 43 is provided between the sealing bracket 4 and the sliding bracket 3, and the sealing spring 43 is used to always keep the sealing ring 7 pressed against the cup body 200, and also provide elastic force for opening the lid. In addition, a guiding column 42 is provided in the center of the sealing bracket 4, and the guiding column 42 is inserted into the central column 62 of the key to guide the key 6 downward, and a reset spring 44 is provided on the outer sleeve of the guiding column 42, and the reset spring 44 is against the central column 62 of the key to provide the key 6 with rebound and increase the hand feel.
