Description

Technical Field

[0001] This utility model relates to the field of cylinder accessories technology, specifically to a cylinder quick connector. Background Technology

[0002] Cylinder quick-connect plugs are convenient and fast connection devices mainly used in pneumatic systems to connect air hoses and pneumatic components. They allow for quick connection and disconnection of pipelines and equipment, thereby improving work efficiency. Cylinder quick-connect plugs are commonly used in pneumatic systems, especially in situations requiring frequent disassembly and assembly, significantly reducing downtime and increasing production efficiency. Cylinder quick-connect plugs come in various types, commonly including plug-in connectors and male-female connectors. Plug-in connectors are typically used to directly connect two air hoses of the same specification, offering high versatility, easy installation, and suitability for temporary connections and equipment replacement. Male-female connectors, based on different plug and socket designs, provide a more stable connection, especially suitable for equipment operating for extended periods.

[0003] When connecting pneumatic lines to cylinders, quick-connect couplings are required. Quick-connect couplings can be connected with a simple insertion action. However, when using existing quick-connect couplings, external vibrations can cause them to break, resulting in leaks at the joint and affecting subsequent use. When workers use quick-connect couplings in confined spaces, the position of the quick-connect couplings is easily misaligned, making it impossible to quickly align and connect them, resulting in slow installation. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cylinder quick connector, which solves the technical problems of the original quick connector being disconnected due to external vibration during use, causing leakage at the joint and affecting subsequent use, and workers easily misaligning the quick connector when using it in a confined space, resulting in the quick connector not being able to be quickly aligned and connected, causing the joint installation to be slow.

[0005] According to one aspect, at least one embodiment of the present invention provides a cylinder quick connector, comprising: an outer sleeve, a limiting block fixedly installed on the inner side of the outer sleeve, and a spring fixedly installed on the rear end of the limiting block;

[0006] An external connector has an opening on its inner wall, a steel ball is inserted into the opening, a retaining ring is fixedly installed on the outer front end of the opening, and a collar is fixedly installed on the inner rear end of the opening.

[0007] The inner connector is snapped into the inner connector inside the outer connector. The outer wall of the inner connector has a slot. A stop block is fixedly installed at the rear end of the slot. The inner connector has a third inner cavity inside.

[0008] For example, in a cylinder quick connector provided in at least one embodiment of the present invention, a first inner cavity is provided at the front of the outer connector, and a second inner cavity is provided at the rear of the outer connector.

[0009] For example, in at least one embodiment of the present invention, a cylinder quick connector is provided, which further includes a push port fixedly opened at the rear end of the inner connector.

[0010] For example, in at least one embodiment of the present invention, a cylinder quick connector further includes: a mounting shell fixedly connected above the front end of the inner connector, and a telescopic rod fixedly installed inside the mounting shell; a sealing ring fixedly installed at the rear end of the telescopic rod; a first magnetic plate fixedly connected to the inner side of the sealing ring; and a second magnetic plate fixedly installed at the rear end of the first magnetic plate.

[0012] For example, in a cylinder quick connector provided in at least one embodiment of the present invention, the first inner cavity has a larger inner diameter than the second inner cavity, and the cross-section of the first inner cavity and the second inner cavity is T-shaped.

[0013] For example, in a cylinder quick connector provided in at least one embodiment of the present invention, the inner connector has a cross-section of "T" shape, the slot and the steel ball form a snap-fit ​​connection, and the inner diameter of the third inner cavity is the same as the inner diameter of the second inner cavity.

[0014] For example, in a cylinder quick connector provided in at least one embodiment of the present invention, the outer side of the push port is rectangular in shape, and the push port pushes out the steel ball through the rectangular shape.

[0015] For example, in at least one embodiment of the present invention, a cylinder quick connector further includes: the bottom surface of the mounting shell is fitted with the front top surface of the inner connector; the cross-section of the sealing ring is "L" shaped; the first magnetic plate and the second magnetic plate have the same structure; the second magnetic plate is fixedly installed on the front end face of the outer connector; and the mounting shell is symmetrically installed on the upper and lower outer walls of the inner connector with the inner connector as the central reference.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this invention, the inner connector enters the outer connector. The inner connector's rear end pushes out a steel ball from the placement port, pushing it upwards. A groove is provided at the outer end of the inner connector, which engages with the steel ball to fix the inner and outer connectors. This design achieves a sealed connection between the inner and outer connectors, and the outer sleeve locks the connectors together, enabling quick connection between pipes and reducing leakage. Furthermore, an outer sleeve is added to the outer side of the outer connector, and a spring is installed at the rear end of the limiting block.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5As shown, it illustrates a cylinder quick connector in one embodiment of the present invention, comprising: an outer sleeve 1, a limiting block 2 fixedly installed on the inner side of the outer sleeve 1, and a spring 3 fixedly installed on the rear end of the limiting block 2;

[0032] The outer connector 4 has an inner wall with a placement opening 5. A steel ball 6 is inserted into the placement opening 5. A retaining ring 7 is fixedly installed on the outer front end of the placement opening 5. A collar 8 is fixedly installed on the inner rear end of the placement opening 5.

[0033] The inner connector 11 is snapped into the inner connector 4. The outer wall of the inner connector 11 has a slot 12. A stop block 13 is fixedly installed at the rear end of the slot 12. The inner connector 11 has a third inner cavity 14.

[0034] For example, such as Figure 2 As shown, a first inner cavity 9 is provided at the front of the inner side of the external connector 4, and a second inner cavity 10 is provided at the rear of the inner side of the external connector 4.

[0035] For example, such as Figure 3 As shown, the rear end of the inner connector 11 is fixedly provided with a push port 15.

[0036] For example, such as Figure 5 As shown, the cross-section of the outer sleeve 1 and the limiting block 2 is "T" shaped. A retaining ring is fixedly installed at the lower end of the placement port 5. The front end of the outer connector 4 is cylindrical and the rear end is conical. A limiting ring is fixedly installed between the cylinder and the cone. A spring 3 is fixedly installed between the limiting block 2 and the limiting ring. The retaining ring 7 limits the forward position of the limiting block 2. The limiting block 2 presses the steel ball 6 downward.

[0037] For example, such as Figure 2 As shown, the inner diameter of the first inner cavity 9 is larger than the inner diameter of the second inner cavity 10, and the cross-section of the first inner cavity 9 and the second inner cavity 10 is T-shaped.

[0038] For example, such as Figure 3 As shown, the cross-section of the inner connector 11 is "T" shaped, the slot 12 and the steel ball 6 form a snap-fit ​​connection, and the inner diameter of the third inner cavity 14 is the same as the inner diameter of the second inner cavity 10.

[0039] For example, such as Figure 3 As shown, the outer side of the push port 15 is rectangular, and the push port 15 pushes out the steel ball 6 through the rectangular shape.

[0040] In some examples, the outer connector 4 has a first inner cavity 9, with a placement opening 5 at the front end of the inner wall of the first inner cavity 9 and a retaining ring 7 on the outer wall. The retaining ring 7 is fastened to the outer wall of the placement opening 5 by a groove. A steel ball 6 is installed inside the placement opening 5. The rear end of the inner connector 11 is threaded. The outer side of the push opening 15 has a rectangular structure, with a retaining groove 12 and a stop block 13 on the outer front end. The inner side contains a third inner cavity 14. When using the quick connector, the worker pushes the outer retaining sleeve 1 to the rear end, compressing the spring 3 to disengage the limiting block 2 from the placement opening 5, allowing the steel ball 6 to move freely within the placement opening 5. The inner connector 11 is then inserted into the outer connector. The first inner cavity 9 of 4 pushes the rectangular structure of the push port 15 to push the steel ball 6 outward. The front end of the push port 15 is equipped with a slot 12, and a stop block 13 is installed on the rear side of the slot 12. When the push port 15 pushes the steel ball 6 out, the inner connector 11 continues to insert. After the steel ball 6 passes the stop block 13, it is locked into the slot 12, completing the mechanical locking. After installation, the outer sleeve 1 is released, and the spring 3 rebounds to push the limit block 2 forward, so that the limit block 2 covers the placement port 5, restricting the steel ball 6 from falling out. A retaining ring 7 is added to the front end of the placement port 5. The retaining ring 7 prevents the limit block 2 from moving too far forward, ensuring the limiting accuracy.

[0041] For example, such as Figure 4 As shown, a cylinder quick connector is provided in another embodiment of the present invention, including an inner connector 11 with a mounting shell 16 fixedly connected above the front end, a telescopic rod 17 fixedly installed inside the mounting shell 16, a sealing ring 18 fixedly installed at the rear end of the telescopic rod 17, a first magnetic plate 19 fixedly connected to the inner side of the sealing ring 18, and a second magnetic plate 20 fixedly installed at the rear end of the first magnetic plate 19.

[0042] For example, such as Figure 4 As shown, the bottom surface of the mounting shell 16 is in contact with the front top surface of the inner connector 11, the cross-section of the sealing ring 18 is "L" shaped, the first magnetic plate 19 and the second magnetic plate 20 have the same structure, the second magnetic plate 20 is fixedly installed on the front end face of the outer connector 4, and the mounting shell 16 is symmetrically installed on the upper and lower outer walls of the inner connector 11 with the inner connector 11 as the center reference.

[0043] In some examples, the inner connector 11 has a T-shaped cross-section, consisting of an inner tube (front end) and a mounting tube (rear end). A mounting shell 16 is fixed above the mounting tube. A first magnetic plate 19 is embedded at the connection between the inner tube and the mounting tube, used for adsorption and alignment with the second magnetic plate 20 of the outer connector 4. The front end face of the outer connector 4 is embedded with the second magnetic plate 20, which is adsorbed with the first magnetic plate 19 of the inner connector 11 to ensure rapid alignment. Through the magnetic attraction between the first magnetic plate 19 and the second magnetic plate 20, the T-shaped front end of the inner connector 11 is automatically aligned with the first inner cavity 9 of the outer connector 4. The mounting shell 16 is connected by a telescopic rod 17. The sealing ring 18 can be moved axially to achieve sealing adjustment. The connection between the outer connector 4 and the outer sleeve 1 is provided with a double-layer sealing ring 18 (controlled by the telescopic rod 17). When the inner connector 11 is inserted, the push port 15 pushes open the steel ball 6, so that it is locked into the slot 12. The telescopic rod 17 of the mounting shell 16 pushes the sealing ring 18 forward to close the gap between the outer connector 4 and the outer sleeve 1. The double-layer sealing ring 18 is tightly pressed against the gap under the pressure of the telescopic rod 17 and is linked with the internal valve. When the inner connector 11 is pulled out, the magnetic plate separates, the telescopic rod 17 retracts and drives the sealing ring 18 to reset, and the valve closes automatically.
