Description

Technical Field

[0001] The utility model relates to a quick hose connector, belonging to the field of chemical equipment. Background Art

[0002] Existing industrial rubber hose quick connectors have many problems such as leakage and unreliable connection. Since the existing quick connectors are made of cast iron, they cannot be rust-proof and corrosion-resistant, and leakage will occur after a long time; the pins of the quick connectors are prone to failure and looseness after a long time of use. This leads to frequent replacement due to leakage of the quick connectors, and the quick connector hoses are more expensive than ordinary hoses; loosening at the connection of the body or loosening of the pins due to failure is likely to cause medium leakage, increasing the on-site dynamic safety risk and being unsafe. Summary of the Invention

[0003] According to the problems described in the background, the problems to be solved by the utility model are:

[0004] Existing quick connectors are prone to leakage and unreliable connection after long-term use.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A hose quick connector includes a fastening sleeve and an anti-disengagement hook. The fastening sleeve includes a fastening wire sleeve, a threaded hole plate and a fastening screw. A threaded hole is provided at the center of the threaded hole plate, and the fastening screw is connected to the threaded hole plate through the threaded hole. After the two ends of the fastening wire sleeve cross, they are respectively connected to the tail end of the fastening screw and the threaded hole plate; the tail of the anti-disengagement hook is connected to the threaded hole plate, and the anti-disengagement hook hooks the anti-disengagement ring, and the anti-disengagement ring is fixed on the interface flange.

[0007] Preferably, the two ends of the fastening wire sleeve are respectively fixed on both sides of the threaded hole plate, and the middle part is wound and fixed on the tail of the fastening screw.

[0008] Preferably, one or more fastening wire sleeves are provided on the hose quick connector.

[0009] Preferably, the tail of the anti-disengagement hook is connected to the threaded hole plate through a bolt.

[0010] After the fastening wire sleeves cross, they are respectively connected to the tail end of the fastening screw and the threaded hole plate to form a circular sleeve that fits outside the hose; by rotating the fastening screw, the distance between the tail of the screw and the threaded hole plate is adjusted. The farther the distance, the farther the two ends of the fastening wire sleeve are pulled, and the smaller the formed circular sleeve is, making the hose more tightly connected to the interface flange. Hook the anti-disengagement hook on both sides of the valve or fix an anti-disengagement ring on the interface flange for convenient hanging. When the pressure in the pipe is too high and the joint is not fastened properly, it can prevent the hose and the hose quick connector from detaching from the interface flange, causing splashing and injury.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. It is used outside the rubber hose and does not come into contact with the medium transported by the rubber hose, so it will not be corroded; it has a simple and reliable structure and is not prone to leakage during long-term use.

[0013] 2. The material cost is low, and the materials used are mostly common industrial materials, which is convenient for maintenance and replacement of components.

[0014] 3. The anti-disengagement hook is added, improving safety.

[0015] 4. The connection is fast. There is no complex connection relationship between the rubber hose and the rubber hose quick connector. Whether replacing the rubber hose or the rubber hose quick connector, it is very convenient. In the handling of some emergency accidents, it can improve the speed of temporary pipe connection and enhance the handling capacity. Description of the Drawings

[0021] Embodiment 1

[0022] As Figure 1 and Figure 2 shown, a rubber hose quick connector includes a fastening sleeve and an anti-disengagement hook 4. The fastening sleeve includes a fastening wire sleeve 1, a threaded hole plate 2, and a fastening screw 3. A threaded hole 21 is provided at the center of the threaded hole plate 2. The fastening screw 3 is connected to the threaded hole plate 2 through the threaded hole 21. After the two ends of the fastening wire sleeve 1 cross, they are respectively connected to the tail end of the fastening screw 3 and the threaded hole plate 2; the tail of the anti-disengagement hook 4 is connected to the threaded hole plate 2.

[0023] One or more fastening wire sleeves 1 are provided on the rubber hose quick connector.

[0024] The tail of the anti-disengagement hook 4 is connected to the threaded hole plate 2 through a bolt.

[0025] It is used outside the rubber hose and does not come into contact with the medium conveyed by the rubber hose, so it will not be corroded. It has a simple and reliable structure and is not prone to leakage during long-term use. The anti-disengagement hook 4 is added, improving safety; the connection is fast, and there is no complex connection relationship between the rubber hose and the rubber hose quick connector, making it convenient to replace either the rubber hose or the rubber hose quick connector. During the handling of some emergency accidents, it can improve the speed of temporary pipe connection and enhance the handling capacity.
