Description

Technical Field

[0001] The utility model relates to the technical field of aerator buoy connection, in particular to an aerator connector fixed connection structure. Background Art

[0002] An aerator is a machine commonly used in the fish farming industry. Its main function is to increase the oxygen content in the water to ensure that the fish in the water do not suffer from oxygen deprivation. It can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pond water, which threatens the living environment of the fish. Aerators generally rely on their own air pump to pump air into the water to achieve the purpose of increasing the oxygen content in the water. Aerators usually require floats to provide buoyancy so that the aerator floats on the water surface. In order to prevent the aerator from tipping over, three floats are usually set up and separated. This makes it less likely to tip over, but it will also cause the problem of loose connections. Because aerators are usually outdoors all the time, the environment is relatively harsh. The connecting rod connecting the floats is on the water surface for a long time, especially the connection part, which is very easy to fall off from the outside of the connector. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose an aerator connector fixed connection structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A fixed connection structure of an aerator connector comprises a connector, wherein connecting rods are embedded in the inner and outer sides of the connector, a pin is vertically embedded in the interior of the connector, and a cotter pin is embedded in the top of each pin.

[0006] Preferably, the inner and outer sides of the connector are provided with three connection ports arranged equidistantly in a circular shape, the connecting rod is just embedded in the connection ports of the connector, and the outer wall of the connecting rod is in close contact with the connection ports.

[0007] Preferably, the upper and lower ends of the connecting rod near the middle of the connector are both vertically opened with fixing openings. When the connecting rod is fully embedded in the connecting opening of the connector, the pin shaft is set between the connecting opening of the connector and the fixing opening of the connecting rod.

[0008] Preferably, the cotter pin is embedded in the upper part of the inner portion of the pin shaft in a bent shape, and the bottom end of the cotter pin is in close contact with the upper surface of the cotter pin.

[0009] When the connecting rod is completely embedded in the connecting port of the connector, the pin on the connector can be embedded in the fixing port of the connecting rod to fix the connecting rod, so that the connecting rod is not easily detached from the connecting port of the connector. At the same time, it can also prevent the part of the connecting rod embedded in the connecting port from rusting, making the connecting rod not easy to loosen, thereby making the connection between the connecting rod and the connector more secure.

[0014] LEGEND DESCRIPTION:

[0015] Connector 1, connecting rod 2, pin shaft 3, split pin 301. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Embodiment 1, referring to Figures 1-4 , an oxygenator connector fixed connection structure, including a connector 1, a connecting rod 2 is embedded on the inner and outer sides of the connector 1, a pin shaft 3 is vertically embedded inside the connector 1, and split pins 301 are embedded on the tops of the pin shafts 3.

[0017] There are three connection ports arranged equidistantly in a circular ring shape on the inner and outer sides of the connector 1, and the connecting rod 2 is exactly embedded in the connection port of the connector 1, and the outer wall of the connecting rod 2 is in close contact with the connection port;

[0018] Fixing ports are vertically opened at the upper and lower ends of one side of the connecting rod 2 close to the middle of the connector 1. When the connecting rod 2 is completely embedded in the connection port of the connector 1, the pin shaft 3 is arranged through between the connection port of the connector 1 and the fixing port of the connecting rod 2;

[0019] When the connecting rod 2 is completely embedded in the connection port of the connector 1, the pin shaft 3 on the connector 1 can be exactly embedded in the fixing port of the connecting rod 2 to fix the connecting rod 2, so that the connecting rod 2 is not easily separated from the connection port of the connector 1. At the same time, it can also prevent the part of the connecting rod 2 embedded in the connection port from rusting, making the connecting rod 2 not easily loose, and thus making the connection between the connecting rod 2 and the connector 1 more firm.

[0020] Embodiment 2, the difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the split pin 301 is bent and embedded above the inside of the pin shaft 3, and the bottom end of the split pin 301 is in close contact with the upper surface of the split pin 301;

[0021] When the split pin 301 is embedded in the pin shaft 3, the pin shaft 3 can be fixed to prevent the pin shaft 3 from falling off from the connector 1;

[0022] When the split pin 301 is embedded above the pin shaft 3, the bottom of the split pin 301 is closely attached to the upper surface of the connector 1 to limit and fix the pin shaft 3, so as to avoid the internal wear of the connector 1 and the connecting rod 2 caused by the long-term up and down movement of the pin shaft 3.

[0023] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
