Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline joints, and in particular to a pneumatic connection joint. Background Art
[0002] A quick connector is an assembly widely applicable to the connection between pipe fittings. Its design purpose is to provide the function of quickly inserting and fitting the connector and the pipe fittings. Its basic structure usually uses the steel ball clamping method to fix the connector and the pipe fittings, and can also be quickly implemented when separating the pipe fittings, so as to achieve the convenience and practicality of quickly disassembling and loosening between the connector and the pipe fittings.
[0003] The existing quick connector includes a male connector 1, a female connector 2 and a sleeve 3. The male connector 1, the female connector 2 and the sleeve 3 are all circular tubes. One end of the male connector 1 is hermetically abutted inside one end of the female connector 2. Threads are provided on the inner walls of the ends of the male connector 1 and the female connector 2 that are away from each other. The sleeve 3 is slidably sleeved outside the female connector 2. A through hole is formed through the abutting position of the female connector 2 and the male connector 1. A spherical ball 4 is embedded in the through hole. The diameter of the ball 4 is greater than the depth of the through hole. The inner wall of the sleeve 3 abuts against the ball 4. A notch is formed on the male connector 1. The notch gradually becomes deeper from both ends in the length direction of the male connector 1 to the middle. One side of the ball 4 away from the sleeve 3 abuts against the male connector 1 through the notch.
[0004] In view of the above related technologies, the connection between the existing male connector 1 and the female connector 1 only relies on the action of the ball 4 and the sleeve 3. When fluid flows through the quick connector, the impact force of the fluid flow will cause the male connector 1 and the female connector 2 to separate. At this time, the fluid in the quick connector will spray, affecting the safety of the surrounding staff. Therefore, it needs to be improved. Content of the Utility Model
[0005] In order to improve the safety of the quick connector, the present application provides a pneumatic connection joint.
[0006] The pneumatic connection joint provided by the present application adopts the following technical solutions:
[0007] A pneumatic connection joint includes a male connector, a female connector, a ball and a positioning component. One end of the male connector is detachably connected to one end of the female connector. The end of the male connector away from the female connector and the end of the female connector away from the male connector are both used to connect to external pipelines. A receiving cavity is formed at the connection position of the male connector and the female connector. The ball and the positioning component are both arranged in the receiving cavity. A groove is also formed on the inner wall of the male connector. The ball abuts against the groove. The positioning component is used to tightly abut the ball in the receiving cavity.
[0008] The positioning component includes a slider and a pin. The slider is slidably connected to the male connector and is used to press the ball against the female connector. The slider is located between the ball and the pin. One end of the pin passes through the male connector and contacts the slider. The pin is used to control the slider to move in the direction close to the ball.
[0009] By adopting the above technical solution, during use, the end parts of the male connector and the female connector that are away from each other are respectively inserted or screwed into the fluid pipes to be connected. The ball is abutted between the female connector and the male connector through the groove and the slider, thereby connecting the end parts of the two fluid pipes. While the pin restricts the position of the slider, it also plays a role in connecting the male connector and the female connector, achieving improved stability of the connection between the male connector and the female connector and enhancing the safety of the quick connector.
[0010] If the pin is pulled out, at this time the pressing force of the slider on the ball disappears. Then, by controlling the male connector to move in the direction away from the female connector, the ball will be pushed up by the male connector, and the end part of the male connector can be separated from the end part of the female connector, thus disconnecting the end parts of the two fluid pipes.
[0011] Preferably, an arc surface is provided on the side of the slider close to the ball, and the arc surface is fitted with the ball.
[0012] By adopting the above technical solution, the arc surface can better fit with the ball to increase the contact area between the slider and the ball.
[0013] Preferably, a wedge-shaped guiding surface is provided on the side of the slider away from the ball. When the end of the pin abuts against the wedge-shaped guiding surface, the slider moves in the direction close to the ball.
[0014] By adopting the above technical solution, during the process of the pin being gradually inserted, the end will abut against the wedge-shaped guiding surface of the slider. At this time, the acting force of the pin on the slider will have a horizontal component force to control the horizontal movement of the slider, so that the slider presses tightly on the ball.
[0015] Preferably, protective layers are coated on the outer surfaces of the male connector and the female connector.
[0016] By adopting the above technical solution, on the one hand, the protective layer can increase the aesthetic degree of the outer surfaces of the male connector and the female connector, and on the other hand, it can play a role in anti-corrosion and protection for the entire connector.
[0017] Preferably, a support ring is connected to the end of the male connector away from the female connector. The support ring is hollow, and the support ring is locked to the male connector through a fastener.
[0018] By adopting the above technical solution, the support ring is locked on the male connector through a fastener, and the support ring is used to connect with an external fluid pipeline.
[0019] Preferably, the fastener is a fastening bolt or a fastening screw.
[0020] By adopting the above technical solution, the fastening bolt or the fastening screw belongs to a detachable object, and the detachable connection between the support ring and the male connector can be realized.
[0021] Preferably, a spring washer and a gasket are further included, and the spring washer and the gasket are arranged in sequence along the insertion direction of the fastener.
[0022] By adopting the above technical solution, when the fastener is tightened, the elastic part of the spring washer will be compressed, thereby generating a force to resist loosening, preventing the fastener from loosening under vibration or other stresses, and improving the reliability and safety of the joint.
[0023] Preferably, a retaining ring is further included, and the retaining ring is connected to the male connector and is located at the docking position of the male connector and the female connector.
[0024] By adopting the above technical solution, the retaining ring can improve the sealing performance at the connection of the male connector and the female connector, and reduce the possibility of fluid leakage.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] (1) By setting the positioning component, the slider generates a pressing force on the ball under the action of the plug pin, thereby realizing the restriction of the ball; at the same time, the plug pin also plays a role in connecting the male connector and the female connector, improving the connection stability of the male connector and the female connector, and enhancing the safety of the quick connector during use.
[0027] (2) By setting an arc surface on the slider, the arc surface can better fit with the ball to increase the contact area between the slider and the ball.
[0028] (3) By setting the retaining ring, the retaining ring can improve the sealing performance at the connection of the male connector and the female connector, and reduce the possibility of fluid leakage. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection; it can also be a detachable connection; or integrated; it can also be a mechanical connection. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.
[0037] Next, some embodiments of the present application will be described in detail with reference to the accompanying drawings. Without conflict, those skilled in the art can combine and combine the different embodiments or examples represented in the present application and the features of different embodiments or examples.
[0038] The embodiments of the present application disclose a pneumatic connector. Refer to Figure 1, the pneumatic connection joint includes a male joint 1, a female joint 2, a ball 4 and a positioning component 5. Both the male joint 1 and the female joint 2 are in a circular tubular shape, and one end of the male joint 1 is sealingly abutted against one end of the female joint 2. In some embodiments, a retaining ring 6 is also installed on the male joint 1, and the retaining ring 6 is at the docking position of the male joint 1 and the female joint 2. The retaining ring 6 can improve the sealing performance at the connection of the male joint 1 and the female joint 2 and reduce the possibility of fluid outflow. One end of the male joint 1 away from the female joint 2 and one end of the female joint 2 away from the male joint 1 are both used to connect with external pipelines. A receiving cavity 7 is formed at the connection position of the male joint 1 and the female joint 2, and both the ball 4 and the positioning component 5 are installed in the receiving cavity 7. A groove 8 is also formed on the inner wall of the male joint 1, and a part of the ball 4 abuts against the groove 8. The positioning component 5 is used to press the ball 4 tightly in the receiving cavity 7. In this embodiment, protective layers are coated on the outer surfaces of both the male joint 1 and the female joint 2, and the protective layers can be, but are not limited to, metal layers, non-metal layers and chemical layers. On the one hand, the protective layers can increase the aesthetic degree of the outer surfaces of the male joint 1 and the female joint 2, and on the other hand, they can play a role in anti-corrosion and protection for the whole joint.
[0039] The positioning component 5 includes a slider 51 and a pin 52. The slider 51 is slidably connected to the male joint 1 and is used to press the ball 4 tightly against the female joint 2. The slider 51 is located between the ball 4 and the pin 52. As for the way of sliding of the slider 51, existing conventional structures can be adopted, such as setting a chute, which will not be elaborated here. One end of the pin 52 passes through the male joint 1 and contacts the slider 51. The pin 52 is used to control the slider 51 to move in the direction close to the ball 4.
[0040] During the use process, the end parts of the male joint 1 and the female joint 2 away from each other are respectively screwed to the fluid pipelines to be connected. The ball 4 abuts between the female joint 2 and the male joint 1 through the groove 8 and the slider 51, thereby connecting the end parts of the two fluid pipelines. While the pin 52 plays a role in restricting the position of the slider 51, it also plays a role in connecting the male joint 1 and the female joint 2, realizing the improvement of the connection stability of the male joint 1 and the female joint 2 and enhancing the safety of the quick connector.
[0041] If the pin 52 is pulled out, at this time the pressing force of the slider 51 on the ball 4 disappears, and then the male joint 1 is controlled to move in the direction away from the female joint 2, and the ball 4 will be lifted by the male joint 1, and the end part of the male joint 1 can be separated from the end part of the female joint 2, so that the end parts of the two fluid pipelines are disconnected.
[0042] Among them, an arc surface 9 is provided on one side of the slider 51 close to the ball 4. The arc surface 9 fits with the ball 4 and is in close contact with the ball 4 to increase the contact area between the slider 51 and the ball 4. A wedge-shaped guiding surface 10 is provided on the side of the slider 51 away from the ball 4. During the gradual insertion of the plug pin 52, the end portion will abut against the wedge-shaped guiding surface 10 of the slider 51. At this time, the plug pin 52 will have a horizontal component force acting on the slider 51, causing the slider 51 to move in the direction close to the ball 4 and pressing the ball 4 tightly.
[0043] Specifically, a support ring 11 is connected to one end of the male connector 1 away from the female connector 2. The support ring 11 is hollow. The support ring 11 is locked to the male connector 1 through a fastener 14. The fastener 14 is a common detachable object such as a fastening bolt or a fastening screw. In this embodiment, a support ring 11 is also installed at one end of the female connector 2 away from the male connector 1. The support rings 11 on the male connector 1 and the female connector 2 are both used to connect to an external fluid pipeline.
[0044] In addition, in some embodiments, a spring washer 12 and a gasket 13 are further installed on the support ring 11. The spring washer 12 and the gasket 13 are arranged in sequence along the insertion direction of the fastener 14. One end of the fastener 14 passes through the spring washer 12 and the gasket 13 at the same time and locks the two on the support ring 11. When the fastener 14 is tightened, the elastic part of the spring washer 12 will be compressed, thereby generating a force to resist loosening and preventing the fastener 14 from loosening under vibration or other stresses, improving the reliability and safety of the joint.
[0045] The implementation principle of a pneumatic joint in an embodiment of the present application is as follows: During use, the end portions of the male connector 1 and the female connector 2 away from each other are respectively inserted or screwed to the fluid pipelines to be connected. The ball 4 abuts against the female connector 2 and the male connector 1 through the groove 8 and the slider 51, thereby connecting the end portions of the two fluid pipelines. While the plug pin 52 restricts the position of the slider 51, it also plays a role in connecting the male connector 1 and the female connector 2, realizing the improvement of the connection stability between the male connector 1 and the female connector 2 and enhancing the safety of the quick connector.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
