Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a gas path self-detaching connector. Background Art

[0002] A connector is a device used to achieve electrical connection between electronic devices. It is also called a connector, plug and socket, etc. It is mainly used to connect two or more electronic components, circuits or devices to achieve signal, current or data transmission.

[0003] Connectors are categorized into push-pull, snap-on, and threaded types based on ease of operation and usage environment. Push-pull connectors are divided into self-locking and self-detaching types, offering advantages like ease of operation and quick plugging and unplugging. Self-detaching connectors are used in scenarios where quick plugging and unplugging is required and vibration resistance is less critical.

[0004] Gas connectors are devices used to connect components in a gas system, enabling gas transmission, distribution, and control. They ensure the system's tightness and allow gas to flow along predetermined paths and within specified requirements. They are widely used in various fields requiring gas transmission and control, such as industrial automation, medical equipment, pneumatic tools, and aerospace.

[0005] However, traditional gas line connectors are all push-pull self-locking connectors. Summary of the Invention

[0006] Based on this, it is necessary to provide a gas path self-detaching connector.

The above-mentioned air path self-detaching connector realizes the air path through-through of the air path connection seat through the cooperation of the inner shell, the positioning ball, the sealing gasket and the outer shell, and can realize the air path connection of the air path self-detaching connector. On the one hand, through the mutual cooperation of the positioning ball, the sealing gasket and the inner shell, it is conducive to realizing that the extraction force of the air path self-detaching connector after plugging is greater than the ventilation air pressure during operation and the environmental impact during operation, thereby meeting the normal working requirements of the air path self-detaching connector; on the other hand, through the mutual cooperation of the inner shell, the sealing gasket and the outer shell, there is no need to use additional glue or rubber strips for gluing, nor is there any need to adopt an additional sealing structure. After the air path self-detaching connector is plugged in, the air tightness can be ensured by squeezing the sealing gasket, which simplifies the process and avoids the pollution problem caused by gluing; on the other hand, when the air path self-detaching connector needs to be quickly disconnected, it only needs to apply force to a certain extent to achieve quick disconnection, thereby achieving the technical effect of quick plugging and unplugging, which is suitable for application scenarios that require quick plugging and unplugging and do not have high requirements for anti-vibration; on the other hand, the air path self-detaching connector has the advantages of simple structure and convenient assembly, which is conducive to cost control and easy to promote and apply. The following is combined with Figures 1 to 13 , the gas path self-detachable connector is described in detail.

[0063] In some embodiments, a gas path self-detachable connector 100 is as follows: Figure 1 As shown, it includes a gas connection seat 200 as shown in FIG. Figure 2 and Figure 3 As shown, combined Figure 4 The air path connection seat 200 includes an inner shell 210, a positioning ball 220, a sealing gasket 230 and an outer shell 240; Figure 5 and Figure 6The inner shell 210 is provided with an inner shell cavity 212, the sealing gasket 230 is provided with an inner chamber 232, the outer shell 240 is provided with an outer shell cavity 242, and the inner shell cavity 212, the inner chamber 232 and the outer shell cavity 242 are connected; the locking ball 220 is limitedly set on the inner shell 210 so that the locking ball 220 is at most partially located in the inner shell cavity 212; the sealing gasket 230 is sleeved on the outside of the inner shell 210 and abuts against the locking ball 220, so that the locking ball 220 is at most partially separated from the inner shell 210; the outer shell 240 is sleeved on the outside of the sealing gasket 230 and is screwed to the inner shell 210; the sealing gasket 230 is located in the outer shell cavity 242, and the inner shell 210 is at least partially located in the outer shell cavity 242 and at least partially located in the inner chamber 232. Such a design realizes the air path through-through of the air path connecting seat 200 through the cooperation of the inner shell 210, the positioning ball 220, the sealing gasket 230 and the outer shell 240, and can realize the air path communication of the air path self-detaching type connector 100. On the one hand, through the mutual cooperation of the positioning ball 220, the sealing gasket 230 and the inner shell 210, it is conducive to realizing that the extraction force of the air path self-detaching type connector 100 after insertion is greater than the ventilation air pressure during operation and the environmental influence during operation, thereby meeting the normal operation requirements of the air path self-detaching type connector 100; on the other hand, through the mutual cooperation of the inner shell 210, the sealing gasket 230 and the outer shell 240, no additional There is no need to use glue or adhesive strips for gluing, and there is no need to adopt an additional sealing structure. The air tightness can be ensured by squeezing the sealing gasket 230 after the air path self-detachable connector 100 is plugged in, which simplifies the process and avoids the pollution problem caused by gluing. On the other hand, when the air path self-detachable connector 100 needs to be disconnected quickly, it can be quickly disconnected after applying force to a certain extent, thereby achieving the technical effect of quick plugging and unplugging, which is suitable for application scenarios that require quick plugging and unplugging and do not have high requirements for vibration resistance. On the other hand, the air path self-detachable connector 100 has the advantages of simple structure and easy assembly, which is conducive to cost control and easy to promote and apply.

[0064] In order to facilitate the assembly of the snap ball 220, in some embodiments, such as Figure 4 and Figure 6 As shown, the inner shell 210 includes an inner shell body 211, which includes the inner shell cavity 212 and a retaining ball assembly groove 215. The retaining ball 220 is positioned within the retaining ball assembly groove 215. The sealing gasket 230 is sleeved on the outside of the inner shell body 211 and abuts against the retaining ball 220 outside the retaining ball assembly groove 215. The outer shell 240 is threadedly connected to the inner shell body 211. As an example, the retaining ball 220 can only be separated from the retaining ball assembly groove 215 in the installation direction, that is, the retaining ball 220 cannot pass through the retaining ball assembly groove 215 and enter the inner shell cavity 212.

[0065] Such a design, on the one hand, can accurately locate the retaining ball 220 through the limiting structure of the assembly groove, thereby preventing it from falling off or shifting during the assembly process, significantly improving the assembly efficiency and reliability, and the guiding effect of the assembly groove reduces the stringent requirements for assembly accuracy and simplifies the assembly process; on the other hand, the retaining ball 220 is restricted in the assembly groove and cannot enter the inner shell cavity 212, eliminating the risk of the ball blocking the air path, ensuring that the air paths of the inner shell cavity 212, the inner chamber 232 and the outer shell cavity 242 are always unobstructed, and ensuring the stability of the air path connection; on the other hand, the sealing gasket 230 abuts the retaining ball 220, and the outer shell 24 When 0 is screwed to the inner shell body 211, a reliable seal is formed by squeezing the sealing gasket, and no additional sealing structure is required, which not only simplifies the process but also avoids gluing pollution. At the same time, the abutment of the sealing gasket on the ball enhances the stability of the positioning structure, so that the pull-out force after insertion can resist the working air pressure and environmental influences; on the other hand, the screw connection structure makes the assembly of the outer shell and the inner shell body convenient, the detachable design is convenient for maintenance and replacement of parts, and the overall structure is simple, reducing the number of parts and processing complexity, which is conducive to reducing costs and is suitable for promotion and application. At the same time, the characteristics of quick plugging and unplugging are retained, and the plug can be disconnected when a certain degree of force is applied, meeting the needs of fast operation.

[0066] As an example, the locking ball 220 is a steel ball, that is, it has rigidity. When the air path connection end 300 is inserted into the air path connection seat 200, the steel ball abuts the air path connection end 300 and the sealing gasket 230 respectively, so that the outer wall of the sealing gasket 230 tightly abuts the inner wall of the outer shell 240, for example, the outer wall of the sealing gasket body 231 of the sealing gasket 230 tightly abuts the inner wall of the outer shell body 241 of the outer shell 240; or, the locking ball 220 is a rubber ball, that is, it has flexibility. When the air path connection end 300 is inserted into the air path connection seat 200, the rubber ball abuts the air path connection end 300 and the sealing gasket 230 respectively, so that the outer wall of the sealing gasket 230 tightly abuts the inner wall of the outer shell 240. For example, as Figure 4 As shown, the outer shape of the sealing tube portion 213 is cylindrical, the inner wall portion of the sealing gasket body 231 of the sealing gasket 230 is adapted to the outer shape of the sealing tube portion 213, the outer wall portion of the sealing gasket body 231 of the sealing gasket 230 is also cylindrical, and the inner wall portion of the shell body 241 of the outer shell 240 is adapted to the outer shape of the outer wall portion of the sealing gasket body 231, so that the sealing gasket 230 or its sealing gasket body 231 cooperates with the outer shell 240 or its shell body 241 to achieve the effect of air path sealing.

[0067] With this design, on the one hand, when the positioning ball 220 is a rigid steel ball, after the air path connection end 300 is plugged in, the steel ball will squeeze the air path connection end 300 and the sealing gasket 230 synchronously with the rigid abutting force, so that the outer wall of the sealing gasket 230 fits tightly against the inner wall of the shell 240, forming a sealing structure under rigid support, ensuring the stability of the air path under high pressure; if it is a flexible rubber ball, its deformation characteristics can adaptively fill the assembly gap when abutting, and enhance the fit between the sealing gasket 230 and the shell 240 through elastic extrusion, which is especially suitable for scenes with slight assembly errors or vibrations, thereby improving sealing reliability. On the other hand, if Figure 4 As shown, the sealing gasket body 231 of the sealing gasket 230 and the shell body 241 of the shell 240 adopt a cylindrical adaptive design. The outer shape of the sealing tube portion 213 matches the inner wall shape of the sealing gasket 230, forming a coaxial sealing structure of the tube, gasket, and shell. Through the precise adaptation of the geometric shape, the outer wall of the sealing gasket 230 evenly abuts the inner wall of the shell 240 when squeezed by the ball, avoiding the risk of localized air leakage. At the same time, the cylindrical structure facilitates mold processing and mass production, reducing manufacturing precision requirements and processing costs. On the other hand, the embodiments of the present application do not require additional sealants or complex structures. The air path seal can be achieved only through material properties and geometric coordination, simplifying the assembly process while avoiding glue pollution and meeting environmental requirements. The standardized selection of steel balls or rubber balls facilitates spare part replacement. The detachable design of the screw-on shell 240 and the inner shell 210 further reduces maintenance costs and retains the technical characteristics of quick plug-in and pull-out. The connection can be disconnected by applying force to a threshold, meeting the rapid operation requirements of automated equipment or emergency scenarios.

[0068] In some embodiments, such as Figure 4 and Figure 6 As shown, the inner housing body 211 is provided with a sealing tube portion 213, and the ball retaining assembly groove 215 is provided in the sealing tube portion 213. The sealing gasket 230 is sleeved on the outside of the sealing tube portion 213. In this embodiment, the inner housing body 211 is provided with an external thread 214, and the outer housing 240 is provided with an internal thread 244 that matches the external thread 214, so that the outer housing 240 and the inner housing body 211 are threadedly connected. As an example, the number of the ball retaining assembly grooves 215 is at least two and is evenly distributed around the circumference of the sealing tube portion 213.

[0069] With this design, on the one hand, the integrated design of the sealing tube portion 213 and the assembly groove 215 realizes precise positioning and air path protection. The sealing tube portion 213 provides a coaxial assembly reference for the sealing gasket 230, and the cylindrical adaptation structure of its outer wall and the inner wall of the sealing gasket ensures that the sealing gasket is evenly fitted to avoid displacement; and the positioning ball assembly groove 215 is provided in the sealing tube portion 213, which can accurately limit the positioning ball 220 on the plug-in path of the air path connection end 300, ensuring that the positioning ball 220 effectively abuts the air path connection end 300 and the sealing gasket 230 when plugged in, and preventing the positioning ball 220 from falling off into the inner shell cavity 212 through the groove structure, thereby eliminating the risk of air path blockage. On the other hand, the threaded connection enhances the sealing and assembly convenience. When the outer shell 240 and the inner shell body 211 are threadedly connected, the degree of extrusion of the sealing gasket 230 can be accurately controlled by the rotational torque, so that the outer wall of the sealing gasket 230 is tightly against the inner wall of the outer shell 240, forming a sealing mechanism of thread pre-tightening and gasket deformation, without the need for additional glue or complex sealing structure; at the same time, the detachable nature of the threaded connection facilitates later maintenance. When it is necessary to replace the sealing gasket 230 or inspect the positioning ball 220, it is only necessary to unscrew the outer shell 240 to quickly disassemble it, which helps to reduce maintenance costs. On the other hand, such structural integration is conducive to simplifying the manufacturing and assembly processes. The integrated design of the sealing tube 213, the positioning ball assembly groove 215 and the thread reduces the number of parts. The standard thread matching of the inner shell body 211 and the outer shell 240 can be achieved through conventional machining, reducing the mold development cost; the assembly process of the sealing gasket 230 and the thread tightening is simple and easy to operate, which is conducive to adapting to the automated production line and improving mass production efficiency. At the same time, the quick plug-in and pull-out characteristics of the air path self-detachable connector 100 are retained to meet the emergency disconnection needs.

[0070] In some embodiments, such as Figure 7 and Figure 9 As shown, the sealing gasket 230 includes a sealing gasket body 231, which includes the inner chamber 232. The sealing gasket body 231 is sleeved outside the inner shell 210 and abuts the retaining ball 220. The outer shell 240 is sleeved outside the sealing gasket body 231. In some embodiments, the sealing gasket body 231 includes an abutting protrusion 233, which is configured to abut the air path connection end 300 that matches the air path connection seat 200.

[0071] Such a design, on the one hand, the design of the abutting protrusion 233 is conducive to strengthening the sealing and plug-in positioning. The abutting protrusion 233 and the sealing gasket body 231 can be arranged in one piece, or as an example, the abutting protrusion 233 is made of elastic material. When the air path connection end 300 is inserted, the abutting protrusion 233 is squeezed and deformed, tightly fitting the outer wall of the air path connection end 300, forming a first sealing barrier, effectively preventing gas leakage; at the same time, the structure of the abutting protrusion 233 can guide the air path connection end 300 to be inserted accurately, avoiding uneven force on the positioning ball 220 caused by offset, and improving the plug-in stability. On the other hand, the cooperation between the sealing gasket body 231 and the inner shell 210 is conducive to optimizing the locking structure. The sealing gasket body 231 is sleeved on the outside of the inner shell 210 and abuts the locking ball 220. It can limit the locking ball 220 through its own elastic deformation, preventing the locking ball 220 from falling off or shifting in the non-plugging state. At the same time, it assists the locking ball 220 to press against the air path connection end 300 during plugging, ensuring that the linkage sealing mechanism of the locking ball 220 and the sealing gasket 230 in conjunction with the outer shell 240 operates reliably. On the other hand, the nested structure of the outer shell 240 and the sealing gasket body 231 is conducive to simplifying the sealing process. After the outer shell 240 is sleeved with the sealing gasket body 231, the sealing gasket body 231 is squeezed through a threaded connection so that its outer wall is tightly fitted to the inner wall of the outer shell 240. The squeezing of the air path connection end 300 by the abutting protrusion 233 is formed to form a double sealing effect without the need for additional glue or complex seals, reducing process complexity and contamination risks. On the other hand, structural integration is conducive to improving assembly efficiency and compatibility. The inner chamber 232 of the sealing gasket body 231 is connected with the inner shell cavity 212 and the outer shell cavity 242 to ensure that the air path is unobstructed; the standardized design of the abutting protrusion 233 is adapted to air path connection ends 300 of different specifications, and the overall structure can be quickly assembled through nesting and screwing, which is adapted to automated production lines and reduces production costs, while retaining the quick plug-in and pull-out characteristics to meet emergency disconnection needs.

[0072] In some embodiments, such as Figure 7 and Figure 9 As shown, the outer shell 240 is provided with an outer shell body 241, and the outer shell body 241 is provided with the outer shell cavity 242; the outer shell body 241 is sleeved on the outer surface of the sealing gasket 230 and is screwed to the inner shell 210. As an example, in combination with Figure 8 and Figure 10 The shell body 241 is provided with a connecting protrusion 243 , the shell cavity 242 passes through the connecting protrusion 243 , and the connecting protrusion 243 is configured to connect to an external first air pipe.

[0073] Such a design, on the one hand, realizes the quick docking of the first air pipe and the connection of the air path with the connecting protrusion 243, and the outer shell cavity 242 passes through the connecting protrusion 243. The shape of the connecting protrusion 243 can be adapted to the standard first air pipe interface, and the first air pipe can be quickly installed by using an interference fit or a snap-on structure without the need for additional pipe fittings. At the same time, it ensures that the air path of the inner shell cavity 212, the inner chamber 232 of the sealing gasket and the external first air pipe is fully connected, avoiding bending or blockage of the air path and ensuring gas flow efficiency. On the other hand, the screw connection structure is conducive to strengthening the sealing and assembly reliability. The outer shell body 241 and the inner shell 210 are connected by the inner shell external thread 214 and the outer shell internal thread 244. When tightening, the squeezing force on the sealing gasket 230 can be accurately controlled, so that the outer wall of the sealing gasket is tightly attached to the inner wall of the outer shell body. Combined with the squeezing of the air path connection end 300 by the sealing gasket contact protrusion 233, a double sealing effect is formed to prevent air leakage. The detachable nature of the threaded connection facilitates later maintenance, and the sealing gasket can be replaced or the air path can be repaired without destroying the structure. On the other hand, the outer shell body 241 provides protection and structural support. The outer shell body 241 is mounted on the outside of the sealing gasket 230, providing physical protection for the internal retaining ball 220, sealing gasket 230, and other components, preventing external forces from causing component displacement. The integrated design of the connecting protrusion 243 enhances the structural strength of the outer shell body 241, preventing deformation of the outer shell due to external forces when the first air pipe is connected. At the same time, it provides an installation positioning reference for the entire airway self-detachable connector 100, facilitating the rapid plug-in and pull-out operation of automated equipment. On the other hand, the standardized design helps reduce costs and assembly difficulty. The specifications of the connecting protrusion 243 can be designed according to the universal first air pipe size, eliminating the need for customized processing. The threaded fit between the outer shell body 241 and the inner shell 210, as well as the nested structure of the sealing gasket 230, are all processed using conventional machining processes, reducing mold development costs. During assembly, the seal is completed by simply tightening the outer shell 240, without the need for specialized tools or gluing processes, making it suitable for assembly line production. At the same time, it retains the quick plug-in and pull-out characteristics, and the connection can be quickly disconnected by applying force to the threshold, meeting the needs of quick disconnection scenarios.

[0074] In some embodiments, such as Figure 9 and Figure 10 As shown, the housing body 241 is provided with a mounting hole 245, and the mounting hole 245 is configured to mount the housing body 241; in this embodiment, combined with Figure 6 and Figure 7The outer shell 240 is provided with an internal thread 244, and the inner shell body 211 is provided with an external thread 214 that matches the internal thread 244, so that the outer shell 240 and the inner shell body 211 are screwed together. This design, on the one hand, is conducive to standardized positioning and fixation by the design of the mounting hole 245. The mounting hole 245 can be used to mount the outer shell body 241 on an external structure such as a device panel or a bracket by fasteners such as bolts and screws. The hole diameter and hole position layout are adapted to universal installation standards and do not require customized design, thereby improving the compatibility of the gas path self-detachable connector 100 with different devices; the structure in which the mounting hole 245 passes through the outer shell body 241 does not affect the gas path through the outer shell cavity 242, which is conducive to ensuring that the gas flow is not obstructed. On the other hand, the combined design of the mounting hole 245 and the threaded connection enables the outer shell body 241 to be fixed to an external device through the mounting hole, and to form a rigid connection with the inner shell body 211 through the thread, thereby preventing the internal parts of the air path self-detaching connector 100 from shifting due to external forces during the plugging and unplugging process. This structure also provides support for the sealing gasket 230 and the retaining ball 220, ensuring that the air path connection end 300 is evenly stressed during plugging and unplugging, and maintaining the retaining ball 220 in a stable state of contact between the air path connection end 300 and the sealing gasket 230. On the other hand, both the mounting hole 245 and the thread are conventional machined structures, which can be mass-produced without complex molds, reducing manufacturing costs. During assembly, the outer shell body 241 is fixed through the mounting hole 245, and then the thread is tightened to complete the connection between the inner shell 210 and the outer shell 240. The process is simple and easy to operate, suitable for automated production lines, while retaining the quick plugging and unplugging characteristics of the air path self-detaching connector 100 to meet the needs of quick disconnection.

[0075] As an example, Figure 6 As shown, the gas path connection seat 200 directly achieves gas path sealing by cooperating with the inner shell 210, the sealing gasket 230 and the outer shell 240. Specifically, the outer shell 240 abuts against the sealing gasket 230 under the action of the locking ball 220 to achieve a first seal, and the outer shell 240 is screwed to the inner shell 210 to achieve a second seal. The gas path self-detachable connector 100 or its gas path connection seat 200 as a whole does not need to be sealed with a rubber ring or other structural parts to achieve the sealing effect of the gas path connection at the gas path connection seat 200. This design, on the one hand, improves the airtightness of the gas path self-detachable connector 100 by constructing a multiple sealing structure. When the outer shell 240 is screwed to the outer thread 214 of the inner shell body 211 through the internal thread 244, a multi-layer sealing system of the inner shell 210, the sealing gasket 230 and the outer shell 240 is formed, which effectively prevents gas leakage. It is particularly suitable for high-pressure environments and effectively enhances the sealing reliability. On the other hand, during maintenance, the sealing gasket 230 and the locking ball 220 can be removed by simply unscrewing the outer shell 240, which is very convenient and easy to use. The air path connecting seat 200 has a simple structure and few accessories, which facilitates spare parts procurement and quick replacement, reducing maintenance costs.

[0076] In some embodiments, such as Figure 11 As shown, the gas path self-detaching connector 100 also includes a gas path connection end 300, combined with Figure 12 and Figure 13 The air path connecting end 300 is inserted into the inner shell 210 and abuts against the positioning ball 220 in the inner shell cavity 212; the air path tube cavity 320 of the air path connecting end 300 is connected to the inner shell cavity 212. This design, on the one hand, directly connects the air path tube cavity 320 of the air path connecting end 300 to the inner shell cavity 212, forming a complete air path channel of the air path tube cavity 320-inner shell cavity 212-sealing gasket inner chamber 232-outer shell cavity 242, which is conducive to optimizing the air path permeability and flow efficiency, avoiding air path bending or blockage, and ensuring smooth gas flow; the coaxial docking design of the tube cavity and the inner shell cavity reduces air flow resistance and improves gas transmission efficiency, which is suitable for scenarios with high requirements for flow stability. On the other hand, the bidirectional abutment mechanism of the locking ball 220 is conducive to enhancing the stability of the connection. When the air path connection end 300 is inserted into the inner shell cavity 212, the outer wall abuts the locking ball 220, and the other side of the locking ball 220 is squeezed and limited by the sealing gasket 230, forming a rigid abutment structure of the air path connection end 300-locking ball 220-sealing gasket 230. This rigid abutment structure makes the extraction force after insertion greater than the working air pressure and environmental vibration, preventing the connection end from accidentally falling off. At the same time, the ball is limited in the locking ball assembly groove 215 to avoid entering the air path blocking channel. On the other hand, the plug-in fit between the air connection end 300 and the inner shell 210 does not require an additional locking structure. When inserted, the retaining ball 220 is automatically locked. When disconnected, applying a force exceeding a threshold can overcome the abutment force of the retaining ball 220 and quickly pull it out. This achieves the synergy of fast plug-in and pull-out and self-detachment characteristics, and meets the rapid operation requirements of automated equipment or emergency scenarios. In addition, the retaining ball does not fall out of the assembly groove during the plug-in and pull-out process, ensuring structural reliability. On the other hand, when the air connection end 300 is plugged in, it squeezes the sealing gasket 230, causing its outer wall to abut against the inner wall of the outer shell 240. Combined with the elastic seal of the sealing ring 250, a double seal of mechanical abutment and elastic deformation is formed. The adaptive design of the air connection end 300's outer shape and the inner shell cavity 212, such as a cylindrical shape, ensures that the sealing gasket is evenly compressed, avoiding local leakage. At the same time, it is compatible with air path lumens 320 of different specifications, improving application flexibility. In addition, the plug-in assembly of the air circuit connection end 300 and the inner shell 210 does not require tools, the process is simple and easy to operate, and is suitable for automated production lines; the detachable design allows the air circuit connection end 300 or the internal seal to be replaced separately, reducing maintenance costs; the air circuit self-detachable connector 100 has a small number of overall structural parts, and reduces customized processing through standardized plug-in matching, which is conducive to controlling production costs and promoting application.

[0077] In some embodiments, such as Figure 12As shown, the air circuit connection end 300 is provided with a connecting boss 310, a plug-in portion 330, and a retaining groove 340 formed outside the plug-in portion 330. The air circuit lumen 320 extends through the connecting boss 310 and the plug-in portion 330. The connecting boss 310 is configured to connect to a second external air pipe. The plug-in portion 330 is inserted into the inner shell 210, and the retaining groove 340 abuts the retaining ball 220 in the inner shell cavity 212. As an example, the air circuit connection end 300 is provided with a main structure, the air circuit lumen 320 extends through the main structure, the connecting boss 310 is protruding from the main structure, and a portion of the main structure serves as the plug-in portion 330. As an example, the retaining groove 340 is annular and has an arcuate or V-shaped cross-section along the circumference. This design allows the annular retaining groove 340 to circumferentially abut the retaining ball 220 when the connector 330 is inserted into the inner housing 212, forming a rigid abutment structure between the retaining groove 340, retaining ball 220, and the sealing gasket 230. When the arcuate or V-shaped retaining groove 340 contacts the retaining ball 220, the curved or inclined surfaces increase the contact area, evenly distributing the abutment force around the retaining ball 220. This prevents radial displacement of the air connection end 300, ensures that the insertion and removal force exceeds the effects of the operating air pressure and ambient vibration, and prevents accidental disengagement. On the other hand, the contact surface is optimized. The arched-section slot forms a flexible abutment with the ball through an arc transition, which can buffer the impact force during insertion and reduce rigid friction; the V-shaped section relies on the wedge structure to enhance the squeezing effect on the locking ball 220, so that the locking ball 220 can simultaneously squeeze the sealing gasket 230, prompting the outer wall of the sealing gasket to abut more tightly against the inner wall of the shell 240, thereby improving the air tightness; both cross-sectional designs can guide the locking ball 220 to automatically slide into the slot 340 or out of the slot 340 during insertion and removal, realizing the self-detachment characteristics of automatic clamping when inserted and quick disconnection by applying force, which is suitable for quick removal operation scenarios. On the other hand, the circular shape and standard cross-section of the slot 340 can be mass-produced through injection molding or machining without the need for customized molds, thereby reducing manufacturing costs. During assembly, the plug-in connection between the plug-in portion 330 and the inner shell 210 does not require tools, the process is simple, and it is compatible with automated production lines. The detachable design allows the air circuit connection end 300 to be replaced separately, reducing maintenance costs. At the same time, the structure of the slot 340 does not change the overall quick plug-in and pull-out characteristics of the air circuit self-detachable connector 100, thereby meeting the efficient application requirements of industrial scenarios.

[0078] In some embodiments, such as Figure 11 and Figure 12As shown, the gas circuit connection end 300 is further provided with a force-applying portion 350. When the plug-in portion 330 is inserted into the inner shell 210, the force-applying portion 350 is located outside the inner shell 210. For embodiments having a main body structure, as an example, the main body structure is provided with the force-applying portion 350 protruding therefrom, and the force-applying portion 350 is adjacent to the plug-in portion 330, i.e., the force-applying portion 350 is adjacent to the plug-in portion 330. As an example, the force-applying portion 350 is thickened so that when the plug-in portion 330 is inserted into the inner shell 210, the force-applying portion 350 abuts against the outside of the inner shell 210. This design, on the one hand, provides a clear force fulcrum for plugging and unplugging operations, and its convex structure is suitable for applying force with fingers or tools. Especially in scenarios where quick disconnection is required, the force application point can be manually pressed or mechanically applied to trigger the self-detachment mechanism. When the applied force exceeds the abutment force threshold of the retaining ball 220, the air circuit connection end 300 can quickly detach from the inner shell 210, meeting the immediate operation requirements of automated equipment or emergency scenarios. On the other hand, when the force application point 350 abuts the outer wall of the inner shell 210, it can ensure the precise insertion depth of the plug-in portion 330 into the inner shell cavity 212 through physical stop, so that the retaining groove 340 and the retaining ball 220 are accurately aligned and form a circumferential abutment, avoiding excessive compression and failure of the sealing gasket 230 due to excessive insertion, or loose connection due to too shallow insertion. This design strengthens the abutment structure of the retaining groove 340-retaining ball 220-sealing gasket 230 by mechanically limiting, so that the extraction force after insertion is stable and greater than the influence of working air pressure and environmental vibration. On the other hand, the positioning function of the force-applying position 350 ensures that the sealing gasket 230 is evenly squeezed, and the fit between its outer wall and the inner wall of the outer shell 240 is improved due to the precise insertion depth. In combination with the embodiment with the sealing ring 250, a double seal can be formed. At the same time, the structure of the force-applying position 350 abutting the outside of the inner shell 210 prevents the plug-in portion 330 from excessively intruding into the inner shell cavity 212, preventing the communication path between the air path lumen 320 and the inner shell cavity 212 from being blocked, thereby ensuring gas flow efficiency. On the other hand, the thickened force-applying position 350 can serve as a visual or tactile reference during assembly, assisting in quickly aligning the plug-in portion 330 and the inner shell 210 and reducing assembly errors. During disassembly, the force-applying position provides a fulcrum, allowing the outer shell 240 to be unscrewed or the air path connection end 300 to be pulled out without special tools, reducing maintenance time. In addition, the thickened design of the force-applying position 350 enhances the structural strength of the connection boss 310, preventing deformation of the connection body due to concentrated force during insertion and removal, and extending the service life of the component.

[0079] The following examples illustrate the automatic air connector 100. In some embodiments, four retaining balls 220 are first installed into the retaining ball assembly grooves 215 of the inner housing 210. The sealing gasket 230 is then inserted onto the inner housing 210, enclosing the retaining balls 220, thus completing the intermediate assembly. The outer housing 240 is then threadedly tightened to the intermediate assembly, completing the entire assembly as the air connector 200. This structure simplifies the structure and makes assembly more convenient, thanks to the interaction between the four retaining balls, the sealing gasket, and the housing.

[0080] When the air connection end 300 is inserted into the air connection seat 200, it can also be understood that when the air connection end 300 and the air connection seat 200 are plugged together, the sealing gasket 230 and the inner shell 210 will squeeze the locking ball 220, so that the locking ball 220 is aligned with the male end groove, that is, the locking ball assembly groove 215. Moreover, because the sealing gasket 230 and the inner shell 210 exert force on the locking ball 220, it can be locked. The extraction force after the connector is plugged in is greater than the ventilation pressure during operation and the environmental influence during operation, which meets normal operation. When a quick disconnection is required, the male end, that is, the air connection end 300, is pulled outward. When the force reaches a certain level, the connection between the air connection end 300 and the air connection seat 200 can be quickly disconnected. Therefore, it is called a self-detachable air connection structure, which can also be called a quick-detachable air connection structure. Compared with electrical connectors that pass signals and currents, the air self-detachable connector 100 described in each embodiment of the present application passes air or water.

[0081] In contrast, most conventional air connectors have a self-locking structure, while the present invention's self-detachable air connector 100 is a self-detachable structure. This design offers advantages such as simple and quick operation, quick plugging and disconnecting, and the ability to meet performance requirements. It is widely used in situations where vibration requirements are not high. Conventional air connectors typically use glue at threaded connections to ensure airtightness, while the present invention's self-detachable air connector 100 ensures airtightness by squeezing the gasket 230 at the air connection end 300 during insertion. This ensures more reliable airtightness, avoids performance failures caused by missed or poorly applied glue during assembly, and eliminates the need for a glue application process.

[0082] It should be noted that other embodiments of the present application also include a self-detachable air path connector that can be implemented by combining the technical features in the above embodiments, which can also be called a quick-detach air path connector.

[0083] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
