[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 1 to 11 The quick-release structure shown includes a male connector mechanism 01 and a female connector mechanism 02:

[0036] The connecting male connector mechanism 01 includes a male connector body 1 and a male connector push rod 2. The male connector body 1 is coaxially sleeved on the male connector push rod 2, and the male connector body 1 has at least one limiting pin 11 on its outer periphery. Figure 1 As shown, the male push rod 2 is located on one side of the male head body 1, and the male head body 1 is fitted onto the male push rod 2. The male push rod 2 is movably positioned inside the male head body 1. To improve the stability of the connection between the male head mechanism 01 and the female head mechanism 02, a limit pin 11 is provided on the outer periphery of the male head body 1. It should be noted that the limit pin 11 can have many structural forms, such as... Figure 1The protrusions and limiting elements shown on the male connector body 1 can also be screws, rivets, or other structural limiting elements with limiting functions; similarly, in order to make the connection more stable, multiple limiting pins 11 can be provided and arranged around the male connector body 1.

[0037] The female connector mechanism 02 includes a female connector body 3, a female connector push rod 4, and a limiting component 5. One side of the female connector body 3 is coaxially sleeved on the female connector push rod 4, and the other side has a receiving chamber 31 to accommodate the male connector body 1. At least one set of straight grooves 32 and a limiting groove 33 disposed on one side of the straight grooves 32 are provided on the outer periphery of the receiving chamber 31. An opening 34 is provided at the free end of the straight grooves 32, and the limiting component 5 is disposed within the straight grooves 32. Figure 1 , Figure 2 As shown, inside the female head body 3, there is a female head push rod 4 on one side and a receiving chamber 31 connected to the female head push rod 4 on the other side. The straight groove 32 and the limiting groove 33 on the receiving chamber cooperate with the limiting pin 11 to achieve locking of the quick disassembly and assembly structure. It should be noted that the limiting component 5 can have many structural forms, such as a snap-fit ​​structure, a slider locking structure, or other structures that can fix the limiting pin 11 in the limiting groove 33.

[0038] The limiting component 5 is slidably disposed within the linear groove 32. The limiting pin 11 is configured such that when the male head body 1 extends into the receiving chamber 31, the limiting pin 11 pushes the limiting component 5 to slide within the linear groove 32. By rotating the male head body 1 to a fixed angle, the limiting pin 11 enters the limiting groove 33, and the limiting component 5 retracts to its initial position, thereby locking the limiting groove 33. Figure 1 , Figure 2 As shown, when the male connector mechanism 01 extends into the female connector mechanism 02, the position of the limiting pin 11 is first aligned with the position of the opening 34 of the straight groove 32. The male connector mechanism 01 is then pushed inward, and the limiting pin 11 pushes the limiting component 5 inward. When the position of the limiting pin 11 reaches one side of the limiting groove 33, the female connector mechanism 02 is rotated to a fixed angle, so that the limiting pin 11 enters the limiting groove 33. Then, the limiting component 5 is returned to the initial position, and the male push rod 2 and the female push rod 4 are connected. The limiting component 5 locks the limiting pin 11, making the quick disassembly and assembly structure more stable. It should be noted that there are many ways to connect the male push rod 2 and the female push rod 4. It can be connected by a snap-fit, by a thread, or by other structural forms.

[0039] This invention connects the male connector body 1 and the female connector body 3 by inserting the limiting pin 11 on the male connector mechanism 01 into the straight groove 32 on the female connector mechanism 02, rotating the male connector assembly to allow the limiting pin 11 to enter the limiting groove 33, and then locking the limiting pin 11 by the limiting assembly 5. The male connector body 1 and the female connector body 3 are connected, and the internal male connector push rod 2 and the female connector push rod 4 are connected. This achieves quick assembly and disassembly while also improving the stability of the structural connection.

[0040] In some embodiments of the present invention, the connecting female head mechanism 02 further includes an operating cylinder 6, which is sleeved on the outside of the female head body 3. A limiting component 5 is disposed on the operating cylinder 6, and the limiting component 5 includes a stop slider 51 extending into the straight groove 32. Figure 3 As shown, the operating cylinder 6 is sleeved on one end having a receiving chamber 31. A limiting component 5 is fixedly installed on the operating cylinder 6, which is configured as a stop slider 51. When the limiting pin 11 extends into the straight groove 32, the limiting pin 11 contacts the stop slider 51, thus pushing the stop slider 51 to move. In its initial position, the stop slider 51 is located on one side of the limiting groove 33, restricting the limiting groove 33 and locking the limiting pin 11 within the limiting groove 33.

[0041] In some embodiments of the present invention, the female head body 3 also has a first stop 35 and a second stop 36 extending toward the outer periphery of the female head body 3 at both ends. A first spring 7 is also sleeved on the female head body 3. One end of the first spring 7 abuts against the first stop 35, and the other end abuts against the operating cylinder 6. The other end of the operating cylinder 6 abuts against the second stop 36. Please continue to refer to Figure 3 To prevent the operating cylinder 6 from shifting during use, the stop slider 51 locks the limiting pin 11 in the limiting groove 33 to prevent it from falling off. The two ends of the female head body 3 are designed with flanges, and a first spring 7 is sleeved between the first flange 35 and the second flange 36. The first spring 7 fixes the operating cylinder 6, preventing the operating cylinder 6 from shifting at one end of the receiving chamber 31. During installation and disassembly, the operating cylinder 6 is pushed to press the first spring 7, causing the stop slider 51 to move away from the limiting groove 33. After installation, the operating cylinder 6 is returned to its initial position by the elastic force of the first spring 7, thus locking the limiting pin 11.

[0042] There are many ways to connect the male push rod 2 and the female push rod 4. In some embodiments of the present invention, the end of the male push rod 2 that extends into the receiving chamber 31 also has a T-shaped conical limiting rod 12, and a limiting step 13 connecting the T-shaped conical limiting rod 12 and the male push rod 2. For example Figure 4 As shown, the male head body 1 is configured with a T-shaped cone head limiting rod 12 at one end facing the female head body 3, and the T-shaped cone head limiting rod 12 is fixedly connected to the female head body 3.

[0043] By providing a structure on the female head body 3 that is adapted to the T-shaped cone head limiting rod 12, specifically, the female head body 3 is provided with a blind hole 41 facing the receiving chamber 31 and adapted to the shape of the T-shaped cone head limiting rod 12, and a locking assembly 8 for locking the T-shaped cone head limiting rod 12. Figure 5 As shown, the T-shaped cone head limiting rod 12 passes through the blind hole 41 and is locked by the locking assembly 8, so that the male push rod 2 and the female push rod 4 are connected. The cooperation between the blind hole 41 and the T-shaped cone head limiting rod 12 improves the stability of the connection between the push rods, and there will be no detachment or shaking during the movement of the push rods.

[0044] In some embodiments of the present invention, the locking component 8 on one end of the female head body 3 includes a limiting piece 81 that passes vertically through the blind hole 41, and a second spring 82 that abuts against the limiting piece 81 at one end and against the female head body 3 at the other end. The limiting piece 81 has a through hole 83 through which the T-shaped cone-shaped limiting rod 12 passes, and the through hole 83 also has a limiting stop 84 for locking the limiting step 13. Figure 5 , Figure 6 As shown, the limiting plate 81 is located at one end of the blind hole 41 near the receiving chamber 31. By pressing the second spring 82, the through hole 83 of the limiting plate 81 is aligned with the blind hole 41, allowing the T-shaped cone limiting rod 12 to extend into the blind hole 41. When the second spring 82 returns to its initial position, the limiting stop 84 on the limiting plate 81 locks the groove between the T-shaped cone limiting rod 12 and the limiting step 13. The groove locks with the limiting stop 84 on the limiting plate 81, connecting the male push rod 2 and the female push rod 4 together. It should be noted that there are many ways to press the T-shaped cone limiting rod 12. The end of the T-shaped cone limiting rod 12 facing outwards from the female head body 3 can be extended to the outside of the female head body 3. Alternatively, a pressing structure that cooperates with the T-shaped cone limiting rod 12 can be provided on the operating cylinder 6, or other structures can be used to press the T-shaped cone limiting rod 12.

[0045] Through the aforementioned T-shaped cone head limiting rod 12 and locking mechanism, the connection between the male push rod 2 and the female push rod 4 can be achieved. To make the disassembly and assembly structure faster, in some embodiments of the present invention, the female head body 3 also has a tapered pin hole 9. The tapered pin hole 9 has a stepped structure, and a T-shaped tapered pin 91 and a third spring 92 sleeved on the T-shaped tapered pin 91 are movably connected inside the tapered pin hole 9. The T-shaped tapered pin 91 includes a tapered pin head 91a and a connecting rod 91b. The tapered pin head 91a abuts against the operating cylinder 6, and the connecting rod 91b passes through the tapered pin hole 9 and is perpendicularly arranged with the limiting piece 81. One end of the third spring 92 abuts against the tapered pin head 91a, and the other end abuts against the stepped surface of the tapered pin hole 9. Figure 7 As shown, pressing the T-shaped conical pin 91 presses the limiting piece 81. The connecting rod 91b corresponds to the position of the limiting piece 81. When the T-shaped conical pin 91 is pressed, the third spring 92 is compressed. The connecting rod 91b extends out of the stepped platform of the conical pin hole 9 and pushes the limiting piece 81 to move, so that the second spring 82 at the other end of the limiting piece 81 is compressed, thereby aligning the through hole 83 on the limiting piece 81 with the blind hole 41. After the T-shaped conical head limiting rod 12 extends into the blind hole 41, the second spring 82 and the third spring 92 return to their original state together, the T-shaped conical pin 91 returns to the female head body 3, and the limiting piece 81 locks the T-shaped conical head limiting rod 12.

[0046] To facilitate faster pressing of the T-shaped tapered pin 91, in some embodiments of the present invention, an annular groove 61 is provided on the inner diameter of the operating cylinder 6, with the tapered pin head 91a abutting against the annular groove 61. The cross-section of the annular groove 61 is trapezoidal, and the angle between the hypotenuse of the annular groove 61 and the tapered pin head 91a is the same. Please continue to refer to... Figure 7 As shown, the annular groove 61 on the operating cylinder 6 is used to accommodate the T-shaped tapered pin 91. The T-shaped tapered pin 91 is pressed by the bevel of the annular groove 61, causing the T-shaped tapered pin 91 to move toward the limiting piece 81. During installation, the bevel presses the T-shaped tapered pin 91, and during use, it is used to accommodate the T-shaped tapered pin 91.

[0047] In some embodiments of the present invention, the male head body 1 further includes a liquid chamber 14, within which the male head push rod 2 is relatively movable. The end of the male head body 1 near the receiving chamber 14 also has a limiting edge 15, which extends toward the axial direction of the male head body 1. The inner diameter of the limiting edge 15 is smaller than the outer diameter of the male head push rod 2. For example... Figure 4 As shown, the liquid chamber 14 is a sealed space. The male push rod 2 is slidably connected to the male body 1. A locking connection is established between the female push rod 4 and the male push rod 2. The female push rod 4 pushes the male push rod 2, thereby pushing the liquid within the liquid chamber 14. The end of the female push rod 4 furthest from the male push rod 2 is connected to an external drive component. It should be noted that the liquid chamber can be used to store hydraulic oil, but it can also be used to store anesthetics or other liquids.

[0048] Some embodiments of the present invention also provide an anesthesia booster incorporating the quick-assembly structure described above. For example... Figures 8 to 10As shown, the installation method between the male connector mechanism 01 and the female connector mechanism 02 in this invention is as follows: First, the end of the male connector push rod 2 with the T-shaped cone-shaped limiting rod 12 is aligned with the end of the female connector mechanism 02 with the receiving chamber 31. The limiting pin 11 on the male connector body 1 is aligned with the straight groove 32 on the female connector body 3. The male connector push rod 2 is then inserted into the receiving chamber 31, and the limiting pin 11 contacts the stop slider 51. The male connector body 1 continues to move towards the female connector body 3, and the stop slider 51 drives the operating cylinder 6 towards the first stop edge 35, while simultaneously compressing the first spring. 7. The inclined edge of the annular groove 61 inside the operating cylinder 6, which moves towards the first stop edge 35, presses the T-shaped conical pin 91. The T-shaped conical pin 91 compresses the third spring 92. The T-shaped conical pin 91 passes through the conical pin hole 9 and contacts the limiting plate 81, pressing the second spring 82, so that the through hole 83 of the limiting plate 81 corresponds to the position of the blind hole 41 on the female head body 3. Next, continue to push the connecting male head mechanism 01. After the position of the stop slider 51 moves away from the side of the limiting groove 33, the T-shaped conical head limiting rod 12 enters the blind hole 41. The limiting step 13 is inside the through hole 83 of the limiting plate 81, such as... Figure 11 As shown, the male head body 1 is rotated to a fixed angle, causing the limiting pin 11 to enter the limiting groove 33. At the same time, as the force of the limiting pin 11 against the stop slider 51 disappears, the elastic force of the first spring 7 pushes the operating cylinder 6 back to the initial position, the annular groove 61 returns to the upper end of the T-shaped cone pin 91, the third spring 92 pushes the T-shaped cone pin 91 to the initial position, and after the T-shaped cone pin 91 moves away from the limiting piece 81, the second spring 82 pushes the limiting piece 81 back to the initial position, and the limiting stop 84 locks the limiting step 13, so that the T-shaped cone head limiting rod 12 is locked in the blind hole 41, realizing the installation of the male head connection mechanism 01 and the female head connection mechanism 02. When disassembling the male connector mechanism 01 and the female connector mechanism 02, push the operating cylinder 6 to drive the T-shaped tapered pin 91 to press the limiting piece 81, so that the through hole 83 corresponds to the blind hole 41, the stop slider 51 moves away from the side of the limiting groove 33, rotate the male connector body 1 in the opposite direction, so that the limiting pin 11 enters the straight groove 32, and then remove the male connector mechanism 01.

[0049] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
