Description

Technical Field

[0001] This utility model relates to the field of hose connector technology, and more specifically, to a rubber hose with a quick-connect fitting. Background Technology

[0002] Hose fittings are components used to connect hoses to hoses or hoses to equipment, serving to transmit fluids or gases or ensure stable system connections. They are widely used in many fields such as chemical, petroleum, natural gas, food, pharmaceutical, and construction.

[0003] Existing conventional hose fittings, such as threaded fittings, require tightening the threads one turn at a time to achieve connection and seal during installation, which is relatively cumbersome and time-consuming. Flange fittings, on the other hand, require tightening multiple bolts during installation, involving numerous steps and also being cumbersome. Therefore, we propose a rubber hose with a quick-connect fitting. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rubber hose with a quick-connect coupling to solve the technical problems of the current conventional hose structure being cumbersome to connect and inconvenient to operate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rubber hose with a quick-connect fitting, comprising an outer fitting and a hose body, wherein both ends of the hose body are fitted with a fitting assembly and an adjusting assembly, the fitting assembly consists of a sleeve and a insert, and the front end of the insert is fixed inside the front end of the sleeve, forming a clamping cavity between the sleeve and the insert, and the insert is inserted and fixed inside the port of the hose body, the adjusting assembly consists of a rotating sleeve and a clamping sleeve, and the rotating sleeve is rotatably installed on the outer side of the rear end of the clamping sleeve, the outer fitting is connected to the outer end of the fitting assembly, the outer fitting has a bucket-shaped design, and several limiting strips are distributed in a ring array on the outer side of the outer fitting.

[0006] In use, the insert is attached to the end of the flexible tube, with a sealing ring at the connection. The flexible tube is positioned between the clamp and the insert. An external connector is installed at the equipment interface. During installation, the connector is directly inserted into the interface. The limiting strip connects to the limiting port for calibration. During insertion, the locking pin enters through the opening of the locking slot, which is angled. The angled surface presses against the locking pin, causing the inner ring to deflect. Once the locking pin is inside the locking slot, it resets, completing the locking and positioning. This structural design allows the connector to be directly inserted... The device employs an internal lateral locking mechanism to prevent traction from causing the connector to separate, ensuring connection stability. During separation, the rotating sleeve is manually rotated, and the sleeve, through a synchronizing plate, synchronously drives the internal ring to rotate. At this point, the locking pin separates from the locking slot, and then the external connector can be pulled out to complete the separation. The rotating sleeve and the clamping cylinder are connected by a coil spring. After the rotating sleeve is released, the coil spring completes the reset. Through the above structural design, this device can synchronously pull the internal locking structure to displace through external rotation, completing the separation of the lateral locking part, reducing the difficulty of operation, and improving the convenience of equipment operation.

[0007] Preferably, the end of the flexible tube is located inside the clamping cavity, and a sealing ring is provided on the outside of the insert.

[0008] Preferably, the front end of the sleeve has a mating interface, and a limit port is formed in a ring array at the opening of the mating interface. The limit strip is connected to the limit port, and the rear end of the sleeve has a through port in a ring array, which is connected to the mating interface.

[0009] Preferably, the inner cavity of the rotating sleeve is provided with a coil spring, and the two ends of the coil spring are fixedly connected to the rotating sleeve and the clamp. The front end of the clamp is inserted and fixed in the clamp cavity, and the clamp is located between the hose body and the sleeve.

[0010] Preferably, the front end of the rotating sleeve is arranged in a ring array with synchronization plates, and the synchronization plates pass through the through-hole. The front end of the synchronization plates is fixed on the inner ring, and the inner ring is located inside the interface. The surface of the inner ring is distributed with several locking posts.

[0011] Preferably, the external connector connection end has a plurality of bayonet slots in a circular array, and after the external connector connection end is inserted into the interface, the bayonet slots engage with the bayonet post, and the opening end of the bayonet slot has an inclined surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a socket assembly to insert the insert into the end of the flexible tube. A sealing ring is provided at the connection. At this time, the flexible tube is located between the clamp and the insert. The external connector is installed at the equipment interface. During installation, it is directly plugged in. The external connector is inserted into the interface. At this time, the limiting strip connects with the limiting port to complete the calibration. During the insertion process, the locking pin enters from the opening of the locking slot. The opening of the locking slot is designed to be inclined. The inclined surface squeezes the locking pin to deflect the internal ring. When the locking pin enters the locking slot, it resets. At this time, the locking and positioning are completed. Through the above structural design, the connector structure is locked by direct plugging and the internal transverse locking method is completed to prevent the connector from separating due to traction and ensure the connection stability.

[0014] 2. This utility model also incorporates an adjustment component. During separation, the rotating sleeve is manually rotated, and the rotating sleeve synchronously drives the inner ring to rotate via a synchronizing plate. At this time, the locking pin separates from the locking slot, and then the outer connector can be separated by pulling it out. The rotating sleeve and the clamping cylinder are connected by a coil spring. After the rotating sleeve is released, the coil spring completes the reset. Through the above structural design, this device synchronously pulls the displacement of the inner locking structure by external rotation to complete the separation of the lateral locking part, reducing the difficulty of operation and improving the convenience of equipment operation.

A coil spring 40 is provided inside the cavity of the rotating sleeve 401. 2. The coil spring 402 is fixedly connected at both ends to the rotating sleeve 401 and the clamp 403. The front end of the clamp 403 is inserted and fixed in the clamp cavity 306, and the clamp 403 is located between the hose body 2 and the sleeve 301. The insert 302 is inserted into the end of the hose body 2, and a sealing ring is provided at the connection. At this time, the hose body 2 is located between the clamp 403 and the insert 302. The external connector 1 is installed at the equipment interface. During installation, it is directly inserted. The external connector 1 is inserted into the interface 304.

The opening of the locking port 101 is designed to be inclined. The inclined surface presses the locking post 406 to deflect the inner ring 404. When the locking post 406 enters the locking port 101, it resets. At this time, the locking and positioning are completed. Through the above structural design, the connector structure is locked by direct plugging. The internal lateral locking method prevents the connector from separating due to traction and ensures the stability of the connection.

[0023] like Figures 2 to 6As shown, this utility model relates to a rubber hose with a quick-connect coupling, including an outer connector 1 and a hose body 2. The outer connector 1 is connected to the outer end of the sleeve assembly 3. The outer connector 1 has a bucket-shaped design, and several limiting strips 102 are distributed in a ring array on the outer side of the outer connector 1. The front end of the rotating sleeve 401 has a ring array of synchronizing plates 405, and the synchronizing plates 405 pass through the through-hole 305.

When the locking post 406 enters the locking slot 101, it resets, thus completing the locking and positioning. When separating, the rotating sleeve 401 is manually rotated. The rotating sleeve 401 drives the inner ring 404 to rotate synchronously through the synchronizing plate 405. At this time, the locking post 406 separates from the locking slot 101. Then, it can be pulled out to complete the separation of the outer connector 1. The rotating sleeve 401 is connected to the clamping cylinder 403 through the coil spring 402. After the rotating sleeve 401 is released, it resets through the coil spring 402.
