[0006] Preferably, a limiting ring groove is provided at the lower end of the limiting rod, a sealing ring is sleeved on the limiting ring groove, and the sealing ring abuts against the lower end surface of the annular sealing protrusion.

[0007] Preferably, a pop-up member is sleeved on the outer wall of the base, a plurality of protrusions are formed on the upper end of the pop-up member, a spring 1 is provided on the protrusion, and the other end of the spring 1 abuts against a limiting hole opened on the lower end surface of the base.

[0008] Preferably, an extension portion is formed on the outer wall of the upper end of the pop-up member and abuts against the cup mouth.

[0009] Preferably, a limiting groove 1 is provided on the outer wall of the base, and the limiting groove 1 is engaged with a limiting strip 1 formed on the inner wall of the pop-up member.

[0010] Preferably, a second limiting strip is formed on the inner wall of the pop-up component, and the second limiting strip is engaged with a second limiting groove formed on the outer wall of the fastener component.

[0011] Preferably, an opening is formed at the upper end of the end cover, and a limiting rod is passed through the opening.

[0012] Preferably, a limiting block is formed on the lower end of the fastener, and the limiting block is engaged with a limiting sliding groove formed on the base.

[0013] Preferably, the protrusion is engaged with the groove provided on the limiting seat in three phases.

[0014] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: when opening the quick-open cup lid with a self-locking function, it is necessary to first press the middle limit rod to make it drop down before pressing the pressing parts on both sides to open the cup lid. At this time, due to the action of the spring and the movement of the fastener toward the inside of the cup lid, the pop-up part pushes down to realize the automatic pop-up of the cup lid. When closing the cup lid in this way, it is only necessary to press the cup lid and push the pop-up part upward. Since there is no pop-up part to resist the fastener, it moves outward under the action of the spring to realize the snap connection between the fastener and the cup body. This is because the limit rod moves upward due to the action of the spring to realize the sealing effect of the air hole at the lower end. The unlocking process is safe and efficient, and can effectively prevent accidental opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1-4As shown, a quick-open cup lid with a self-locking function comprises a base 1, an end cover 2 arranged on the base 1 and a self-locking assembly 3 arranged between the end cover 2 and the base 1, the side wall of the base 1 is provided with two corresponding grooves 4, the groove 4 is provided with a fastener 5 that is engaged with the cup body, the upper end of the fastener 5 is formed with a pressing portion 6, and the pressing portion 6 is arranged in an opening 7 opened in the side wall of the end cover 2, the self-locking assembly 3 comprises a limiting rod 11 that passes through the cup lid, the lower end of the limiting rod 11 is passed through the limiting seat 12 opened in the base 1, the inner wall of the limiting seat 12 is formed with an annular sealing convex portion 13, the upper end surface of the annular sealing convex portion 13 abuts against a spring 14 sleeved on the limiting rod 11, the upper end of the spring 14 abuts against a protrusion 15 formed on the limiting rod 11, the upper end of the protrusion 15 is provided with a groove 2 16, and the groove 2 16 abuts against the fastener 5.

[0021] The quick-open cup lid with a self-locking function of the present invention needs to press the middle limit rod 11 to make it drop before pressing the pressing parts 6 on both sides to open the cup lid. At this time, due to the action of the spring 10 and the movement of the fastener 5 into the interior of the cup lid, the pop-up part 8 pushes down to realize the automatic pop-up of the cup lid. When closing the cup lid in this way, you only need to press the cup lid to push the pop-up part 8 upward. Since there is no pop-up part 8 to resist the fastener 5, it moves outward under the action of the spring 14 to realize the snap connection between the fastener 5 and the cup body. This is because the limit rod 11 moves upward due to the action of the spring 14 to realize the air hole sealing effect at the lower end. The unlocking process is safe and efficient, and can effectively prevent accidental opening.

[0022] Preferably, the inner wall of the clip 5 is formed with an inclined surface 17, which is adapted to the second groove 16. The clip 5 is provided with the inclined surface 17 so that the limiting rod 11 can be automatically reset under the elastic force of the spring 14, thereby increasing the stability of the structure.

[0023] Preferably, a limiting ring groove 18 is provided at the lower end of the limiting rod 11, and a sealing ring 19 is sleeved on the limiting ring groove 18, and the sealing ring 19 abuts against the lower end surface of the annular sealing protrusion 13. The sealing ring 19 can achieve sealing inside the cup body and improve the sealing performance.

[0024] Preferably, a pop-up member 8 is sleeved on the outer wall of the base 1 , and a plurality of protrusions 9 are formed on the upper end of the pop-up member 8 . A spring 10 is provided on the protrusion 9 , and the other end of the spring 10 abuts against a limiting hole 20 opened on the lower end surface of the base 1 .

[0025] Preferably, the outer wall of the upper end of the pop-up member 8 is formed with an extension portion 30 that abuts against the cup mouth. The extension portion 30 abuts against the cup mouth to achieve the up and down movement of the pop-up member 8, thereby achieving the automatic pop-up effect of the cup cover.

[0026] Preferably, the outer wall of the base 1 is provided with a limiting groove 21, which engages with a limiting strip 22 formed on the inner wall of the ejection member 8. The limiting effect of the limiting strip 22 and the limiting groove 21 can increase the stability of the structure, prevent the ejection member 8 from rotating, and enable it to move only up and down.

[0027] Preferably, a second limiting strip 23 is formed on the inner wall of the pop-up member 8, and the second limiting strip 23 engages with a second limiting groove 24 formed on the outer wall of the latch 5. The limiting effect of the second limiting strip 23 and the second limiting groove 24 can increase the structural stability and prevent the pop-up member 8 from rotating, so that it can only move up and down.

[0028] Preferably, an opening 25 is formed at the upper end of the end cover 2 , and a limiting rod 11 is passed through the opening 25 .

[0029] Preferably, a limiting block 26 is formed on the lower end of the fastener 5 , and the limiting block 26 is engaged with a limiting sliding groove 27 formed on the base 1 .

[0030] Preferably, the protrusion 15 is engaged with the third groove 29 provided on the limiting seat 12 .
