Description

Technical Field

[0001] This utility model relates to aquarium aquaculture technology, and in particular to an anti-detachment connecting pipe for aquarium air pumps. Background Technology

[0002] Currently, air pumps are mostly used to provide oxygen for fish kept in aquariums, such as... Figure 8 As shown, the air guide tube 6, made of rubber material, is fitted onto the air pump outlet tube 5 at the air outlet of the air pump 8. The elasticity of the air guide tube 6 is used to connect the air pump outlet tube 5 together. The air guide tube 6 is then connected to the air distribution device such as the air stone in the aquarium. The air pump 8 sends air through the air guide tube 6 to the air stone, where the air is broken up and enters the water. The problem is that the air pump outlet pipe 5 on the air pump 8 is mostly made of smooth, hard plastic, while the air guide pipe 6, although a flexible tube, has a high degree of rigidity to prevent the pipe wall from collapsing and obstructing airflow when bent. This results in low elasticity of the air guide pipe 6 and weak clamping force between it and the air pump outlet pipe 8. After a period of use, the portion of the air guide pipe inserted into the air pump outlet pipe 5 loses elasticity due to prolonged expansion of the air pipe, further weakening the clamping force between the air guide pipe 6 and the air pump outlet pipe 5. When the air pump 8 operates, it vibrates, causing the air guide pipe 6 to slowly slip off the air pump outlet pipe 5, affecting the air supply to the aquarium. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fish tank air pump anti-detachment connection pipe that prevents the air guide tube fitted on the air pump outlet pipe from falling off.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a fish tank air pump anti-detachment connecting pipe, used to connect the air pump outlet pipe, including a connecting hose and a plastic connecting pipe. The outer peripheral surfaces of both ends of the connecting hose are respectively provided with reinforcing ring platforms. The outer peripheral surfaces of both ends of the plastic connecting pipe are respectively provided with at least one anti-detachment ridge protruding from the outer peripheral surface. One end of the plastic connecting pipe is inserted into the connecting hose and tightly connected to the connecting hose.

[0005] As a preferred technical solution, a central ring platform is provided on the outer peripheral wall of the middle part of the plastic connector, and the anti-detachment protrusions at both ends of the plastic connector are located on both sides of the central ring platform and are symmetrically arranged with each other.

[0006] As a preferred technical solution, the connecting hose is a silicone hose, and a reinforcing ring is provided on the outer periphery of the inner end of the reinforcing ring platform.

[0007] As a preferred technical solution, the connecting hose is a straight pipe or an L-shaped pipe; the length of the reinforcing ring at one end of the connecting hose is greater than the length of the reinforcing ring at the other end.

[0008] As a preferred technical solution, one end of the plastic tube inserted into the connecting hose has at least one anti-detachment protrusion located on the outer side of the inner end of the reinforcing ring.

[0009] The aquarium air pump anti-detachment connecting pipe, which adopts the above technical solution, is used to connect the air pump outlet pipe. It includes a connecting hose and a plastic connector. The outer circumferential surfaces of both ends of the connecting hose are respectively provided with reinforcing rings. The outer circumferential surfaces of both ends of the plastic connector are respectively provided with at least one anti-detachment ridge protruding from the outer circumferential surface. One end of the plastic connector is inserted into the connecting hose and is tightly connected to the connecting hose. In use, one end of the plastic connector is tightly connected to the connecting hose, while the other end is inserted into the opening of one end of the air duct. The other end of the air duct is connected to the air stone in the aquarium. The other end of the connecting hose is then fitted onto the air pump outlet pipe. During operation, the connecting hose between the two reinforcing rings can greatly reduce the vibration generated by the air pump, preventing the vibration from being transmitted to the air duct, which is hard but not very elastic, connected to the plastic connector. The anti-detachment protrusions at both ends of the plastic connector are tightly fitted and firmly connected to the air duct and the connecting hose. At the same time, the reinforcing rings at both ends of the connecting hose can greatly improve the clamping force of the connecting hose on the plastic connector and the air pump outlet pipe, ensuring the reliability of the connection and preventing the air duct from falling off at the air pump outlet pipe.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0013] like Figure 1-6 As shown, the aquarium air pump anti-detachment connecting pipe is used to connect the air pump outlet pipe. It includes a connecting hose 1 and a plastic connector 2. The connecting hose 1 has reinforcing rings 3 protruding from the outer circumference of both ends. The plastic connector 2 has at least one anti-detachment ridge 4 protruding from the outer circumference of both ends. Depending on the air pump 8 used, two, three, or four anti-detachment ridges 4 can be used. One end of the plastic connector 2 is inserted into the connecting hose 1 and tightly connected to the connecting hose 1, while the other end is inserted into the air delivery pipe 6 and tightly connected to the air delivery pipe 6. Utilizing the elasticity of the connecting hose 1, after the plastic connector 2 is inserted into the connecting hose 1, the connecting hose 1 hugs the plastic connector 2 tightly. The anti-detachment ridges 4 increase the friction effect of the contact part between the connecting hose 1 and the plastic connector 2, improving the reliability of the connection. The reinforcing rings 3 can greatly improve the gripping force of the connecting hose 1 on the plastic connector 2, ensuring the reliability of the connection. The other end of the connecting hose 1 is fitted onto the air pump outlet pipe 5. The connecting hose 1 is also firmly fitted onto the air pump outlet pipe 5 using its elasticity. The reinforcing ring 3 also increases the clamping force of the connecting hose 1 onto the air pump outlet pipe 5, ensuring the reliability of the connection and preventing the connecting hose 1 from falling off the air pump outlet pipe 5.

[0014] like Figure 1 and 4 As shown, a central ring platform 9 protrudes from the outer peripheral wall of the middle part of the plastic connector 2, facilitating the insertion of the plastic connector 2 into the connecting hose 1 and the air guide tube 6. Anti-detachment protrusions 4 at both ends of the plastic connector 2 are located on both sides of the central ring platform 9 and are symmetrically arranged. The anti-detachment protrusions 4 are in the shape of annular inverted teeth inclined towards the central ring platform 9, which can improve the reliability of the connection between the plastic connector 2 and the connecting hose 1 and the air guide tube 6.

[0015] like Figure 3 , 5As shown in Figure 6, the connecting hose 1 is a silicone hose. Silicone hoses are soft and highly elastic, and their elasticity does not easily degrade over long-term use. When fitted onto the air pump outlet pipe 5 and the plastic connector 2, they fit tightly and provide good grip. Furthermore, the hose effectively buffers and reduces vibration. A reinforcing ring 7 protrudes from the outer periphery of the inner end of the reinforcing ring 3. The reinforcing ring 7 enhances the pressure and gripping effect of the inner end of the reinforcing ring 3 on the air pump outlet pipe 5 and the plastic connector 2 at that location. The connecting hose 1 can be a straight pipe or an L-shaped pipe, expanding its application range to accommodate air pump outlet pipes 5 or air guide pipes 6 in different directions. The length of the reinforcing ring 3 at one end of the connecting hose 1 is greater than the length of the reinforcing ring 3 at the other end, improving the adaptability of the connecting hose 1 to the specifications and models of the air pump outlet pipe 5 and the plastic connector 2.

[0016] like Figure 2 As shown, at least one anti-detachment ridge 4 is located on the outer side of the inner end of the reinforcing ring 3 at one end of the plastic tube 2 inserted into the connecting hose 1. One or two anti-detachment ridges 4 can be located on the outer side of the inner end of the reinforcing ring 3 to accommodate the length of the connecting hose 1. Because of the presence of the reinforcing ring 3, the wall thickness of the two ends of the connecting hose 1 located on the reinforcing ring 3 is greater than the wall thickness in the middle. Thus, the pressure and the degree of clamping between the two ends of the connecting hose 1 located on the reinforcing ring 3 and the air pump outlet pipe 5 and the plastic tube 2 inserted into the connecting hose 1 are greater than those in the middle part of the connecting hose 1. Therefore, after the plastic tube 2 is inserted into the connecting hose 1, if the anti-detachment ridge 4 is located on the outer side of the inner end of the reinforcing ring 3, that is, at least one anti-detachment ridge 4 is located in the middle part of the connecting hose 1, the inner end of the reinforcing ring 3 will have a blocking effect on the anti-detachment ridge 4 located in the middle part of the connecting hose 1, preventing the plastic tube 2 from coming out of the connecting hose 1.

[0017] During normal use, the anti-detachment ridge 4 of the plastic connector 2 is interference-fitted with the connecting hose 1 and the air guide pipe 6, and the air pump outlet pipe 5 is interference-fitted with the connecting hose 1 to ensure a tight connection. Furthermore, the length of the connecting hose 1 between the two reinforcing rings 3 should be less than the sum of the lengths of the two reinforcing rings 3 to prevent excessive bending between the two reinforcing rings 3.

[0018] like Figure 7 As shown, in use, one end of the plastic connector 2 is inserted into the connecting hose 1, and the other end is inserted into one end of the air guide tube 6. The other end of the air guide tube 6 is connected to the air stone in the aquarium. Then, the other end of the connecting hose 1 is fitted onto the air pump outlet tube 5. The air pump 8 then operates, delivering air through the connecting hose 1, plastic connector 2, and air guide tube 6 to the air stone in the aquarium, where the air stone breaks up the air and releases it into the water. When the air pump 8 is operating, the connecting hose 1 buffers and reduces the vibration generated by the air pump 8, preventing the vibration from being transmitted to the air guide tube 6, which is rigid but not very elastic and is connected to the plastic connector 2. This ensures a secure connection and prevents the air guide tube 6 from falling off at the air pump outlet tube 5.
