When connected, the O-ring 9 and the bevel portion 14 can ensure sealing, and can prevent the problem of vacuum absorption during the removal process. Disconnection can quickly connect to the atmospheric pressure. An air hole 10 is also provided on the bottle cap body 1 to prevent the absorption of reagents to form a vacuum. The heat-sealing film 7 initially covers the end of the plug connector 5 and the air hole 10. Before the bottle cap body 1 and the quick-plug female connector 2 are connected, the heat-sealing film 7 can be torn off first. Secondly, a threaded connection groove 8 is provided on the end of the quick-plug female connector 2 that is away from the bottle cap body 1, and the threaded connection groove 8 is used to achieve hard pipe connection.

[0035] When the bottle cap body 1 and the quick-connect female connector 2 are not connected, the flip cover 4 can be used to cover the outer periphery of the plug connector 5 to play a protective role.

[0036] See also Figure 3-Figure 10 As shown, the locking bottle cap also includes a quick plug-in structure 6, the locking bottle cap is arranged on the quick plug female head 2, and the locking bottle cap is used to lock after the bottle cap body 1 and the quick plug female head 2 are connected, or to unlock before the connected bottle cap body 1 and the quick plug female head 2 are separated.

[0037] An embedding groove 12 is provided at one end of the quick-plug female connector 2 connected to the bottle cap body 1, the bottom end of the embedding groove 12 is open, and the two sides of the inner upper end of the embedding groove 12 are recessed to form a lap groove portion, and a second groove 13 is provided at the top of the embedding groove 12. A first groove 11 is provided at the lower end of the outer wall of the quick-plug female connector 2, and the first groove 11 is away from a side close to the second groove 13.

[0038] Among them, see Figure 8 and Fig. 9 As shown, the quick plug-in structure 6 includes an embedding plate 61 that is inserted and matched with the embedding groove 12, and a through hole 62 for the plug connector 5 to pass through is opened in the middle of the embedding plate 61, and a convex plate 63 is integrally formed at one end of the embedding plate 61 close to the first groove 11. The convex plate 63 is perpendicular to the embedding plate 61, and a first spring 64 is connected between the convex plate 63 and the first groove 11. The side wall of the through hole 62 is straightly opened with a first through hole 66 and a second through hole 67 that intersect each other, and the inner diameter of the first through hole 66 is larger than the inner diameter of the second through hole 67.

[0039] See also Fig.10 As shown, the quick plug-in structure 6 also includes a limiting member 65, wherein the limiting member 65 includes a hollow column 651, a second spring 654 is connected between the hollow column 651 and the second groove 13, a connecting rod 652 is connected to the bottom end of the hollow column 651, a limiting column 653 is fixed to the bottom end of the connecting rod 652, the diameter of the connecting rod 652 is smaller than the diameter of the limiting column 653, and the diameter of the connecting rod 652 is smaller than the inner diameter of the second through hole 67, while the diameter of the limiting column 653 is larger than the inner diameter of the second through hole 67, and the diameter of the limiting column 653 is smaller than the inner diameter of the first through hole 66, so that the connecting rod 652 can freely penetrate the first through hole 66 and the second through hole 67, while the limiting column 653 can only penetrate the first through hole 66, and cannot penetrate the second through hole 67, which means that when the connecting rod 652 is in the state of penetrating the second through hole 67, the bottle cap body 1 and the quick plug female connector 2 cannot be separated at this time.

[0040] Through the above:

[0041] When connecting the bottle cap body 1 and the quick-plug female connector 2, the end of the plug connector 5 can be first passed through the through hole 62, and the convex plate 63 can be pressed toward the plug connector 5. The first spring 64 is compressed to move the embedded plate 61 along the embedded groove 12 so that the first through hole 66 is aligned with the limiting column 653. As the bottle cap body 1 and the quick-plug female connector 2 continue to be plugged in, after the limiting column 653 passes through the first through hole 66, the pressure of the convex plate 63 can be released. During the process of the first spring 64 returning to its original state, the embedded plate 61 can be moved back, and the second through hole 67 can be moved to the position of the connecting rod 652. At this time, the bottle cap body 1 and the quick-plug female connector 2 can be prevented from being separated. After the bottle cap body 1 and the quick-plug female connector 2 are connected, the bottle cap body 1 is connected to the reagent bottle, and then the liquid collection tube 3 can be used to absorb the reagent in the reagent bottle.

[0042] In addition, the O-ring 9 is a low-stroke O-ring, and the bottle cap body 1, the quick-connect female connector 2, and the inclined portion 14 assist in sealing during the unplugging process. The stroke is greater than the stroke of the O-ring 9, so that there is no leakage during the unplugging process, and after unplugging, a small amount of residual reagent remains in the groove of the bottle cap, which is not easily accessible to human hands, thereby increasing safety.
