DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0021] like Figure 1-5 As shown, a quick-opening straight cup includes a cup body 1 and a cup cover 2, wherein the cup cover 2 includes an inner plug 3, a connecting portion 4 fixedly arranged above the inner plug 3, and a cover body 5 movably arranged on the connecting portion 4, a plurality of inserting pieces 28 for being inserted into the inner plug 3 are fixedly arranged at the lower end of the connecting portion 4, and the connecting portion 4 is fixed to the inner plug 3 by inserting the inserting pieces 28. A button 6 for pressing and unlocking is movably provided on the inner plug 3, and the button 6 is located at the center of the above-mentioned connecting part 4 and the cover body 5. A circle of first flange 7 and second flange 8 are fixedly provided in the cup body 1 from top to bottom, and the inner diameter of the second flange 8 is smaller than the inner diameter of the above-mentioned first flange 7. The above-mentioned inner plug 3 rests on the second flange 8. A clamping block 9 that can move toward the outer periphery of the inner plug 3 and be clamped under the above-mentioned first flange 7 is movably provided in the inner plug 3. The button 6 drives the above-mentioned clamping block 9 to move through a transmission structure 10. An opening 11 matching with the above-mentioned clamping block 9 is opened on the outer periphery of the cover body 5, and the opening 11 faces the clamping block 9 after the cover body 5 moves downward. A first spring 12 driving the above-mentioned button 6 to move upward is provided in the inner plug 3, and a second spring 13 driving the above-mentioned cover body 5 to move upward is provided on the connecting part 4.

[0022] When in use, the cup cover 2 is locked by passing the card block 9 through the opening 11 on the cover body 5 and then carding under the first convex edge 7. When unlocking, the button 6 is pressed downward, and the card block 9 is driven by the transmission structure 10 to move into the inner plug 3 and disengage from the first convex edge 7 and the opening 11 on the cover body 5 to complete the unlocking. The cover body 5 moves upward under the drive of the second spring 13, and the card block 9 abuts against the inner wall of the cover body 5. The cup cover 2 can be removed upward. The locking and unlocking are completed by transmission through the mechanical structure, which is more reliable.

[0023] A column 14 extending upward is fixedly provided at the center of the inner plug 3, and a channel 15 penetrating the column 14 in the vertical direction is provided at the center of the column 14. A fixing rod 16 extending downward and inserted into the above-mentioned channel 15 is fixedly provided at the lower end of the button 6. The diameter of the fixing rod 16 is smaller than the diameter of the above-mentioned channel 15. A sealing groove 17 is provided at the lower end of the channel 15, and a sealing plug 18 for clamping in the sealing groove 17 is fixedly provided at the lower end of the fixing rod 16. When unlocking, after the button 6 moves downward, the sealing ring is separated from the sealing groove 17, releasing the pressure inside the cup body 1, making it easier to remove the cup cover 2 and effectively preserving the heat inside the cup body 1 during use.

[0024] The lower end of the button 6 is fixedly provided with a guide sleeve 19 extending downward and sleeved on the above-mentioned column 14. The outer periphery of the guide sleeve 19 is rectangular, and the above-mentioned first spring 12 is located between the column 14 and the guide sleeve 19. The transmission structure 10 includes a plurality of gears 20 rotatably provided on the above-mentioned inner plug 3. The gears 20 are located below the above-mentioned block 9. The outer periphery of the guide sleeve 19 is fixedly provided with racks 21 distributed in the vertical direction. The racks 21 are always meshed with the gears 20, and the lower end of the above-mentioned block 9 is always meshed with the gears 20. The gears 20 are rotatably provided on the above-mentioned inner plug 3 through a rotating shaft, and the inner plug 3, the block 9 and the opening 11 are respectively provided with four gears 20, and the angle between two adjacent gears 20 is ninety degrees. When the button 6 drives the guide sleeve 19 to move downward, the gear 20 is driven to rotate through the rack 21 and drives the block 9 to move toward the guide sleeve 19. Compared with the existing mechanism on the market that uses an inclined slide groove structure to drive the movement, the rolling friction of this structure is smoother and less prone to jamming than the sliding friction of the inclined slide groove.

[0025] A circle of limiting ring 22 is fixedly provided on the outer periphery of the inner plug 3, and the limiting ring 22 abuts against the upper part of the second convex edge 8. A plurality of hooks 23 are fixedly provided on the upper end of the connecting portion 4, and the cover body 5 is sleeved on the outer periphery of the connecting portion 4 and can move between the limiting ring 22 and the hooks 23. A plurality of mounting holes 24 are provided on the upper end of the connecting portion 4, and the second spring 13 is provided in the mounting holes 24 and the upper end of the second spring 13 abuts against the cover body 5. A limiting block 25 is fixedly provided on the upper end of the clamping block 9. A plurality of guide plates 26 are fixedly provided in the connecting portion 4, and a guide groove 27 for clamping the guide plates 26 is provided on the inner wall of the cover body 5. The moving range of the cover body 5 is limited by the limit ring 22 and the hook 23, and the moving range of the block 9 is limited by the limit block 25 set on the card. When in the unlocked state, the lower end of the guide sleeve 19 abuts against the upper end of the inner plug 3, and the end of the block 9 facing the guide sleeve 19 abuts against the guide sleeve 19, and the first spring 12 is in a compressed state. At the same time, the opening 11 on the cover body 5 is located above the block 9. While the position of the block 9 is limited by the limit block 25, the upward movement distance of the button 6 is limited to prevent the button 6 from moving too high and disengaging from the gear 20.

[0026] When locking, the cup cover 2 is placed in the cup body 1, and the limiting ring 22 is pressed against the second convex edge 8, the cover body 5 is pressed downward, the second spring 13 is compressed, and the cover body 5 moves downward until it is pressed against the limiting ring 22. At this time, the opening 11 on the cover body 5 is opposite to the block 9, and the button 6 moves upward under the drive of the first spring 12 and drives the block 9 to move outward through the gear 20 and insert it into the opening 11 on the cover body 5 and press against the bottom of the first convex edge 7 on the cup body 1 to complete the locking of the cup cover 2.

[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
